Recurrent breast cancers often develop resistance to standard-of-care therapies. Identifying targetable factors contributing to cancer recurrence remains the rate-limiting step in improving long-term outcomes. In this study, we identify tumor cell-derived osteopontin as an autocrine and paracrine driver of tumor recurrence. Osteopontin promotes tumor cell proliferation, recruits macrophages, and synergizes with IL-4 to further polarize them into a pro-tumorigenic state. Macrophage depletion and osteopontin inhibition decrease recurrent tumor growth. Furthermore, targeting osteopontin in primary tumor-bearing female mice prevents metastasis, permits T cell infiltration and activation, and improves anti-PD-1 immunotherapy response. Clinically, osteopontin expression is higher in recurrent metastatic tumors versus female patient-matched primary breast tumors. Osteopontin positively correlates with macrophage infiltration, increases with higher tumor grade, and its elevated pathway activity is associated with poor prognosis and long-term recurrence. Our findings suggest clinical implications and an alternative therapeutic strategy based on osteopontin's multiaxial role in breast cancer progression and recurrence. Osteopontin promotes tumor growth in several cancer types. Here, in a preclinical model recapitulating features of human breast cancer recurrence, the authors report that osteopontin promotes the recruitment of immunosuppressive macrophages and its targeting reduces breast tumor growth and metastasis.

Background: Most patients with ovarian cancer relapse within 2 years. Prospective randomized trials, such as DESKTOP III and SOC-I, have shown the role of secondary cytoreduction in improving oncological outcomes in selected patients, when complete tumor resection is achieved. Recent retrospective series suggest that minimally invasive surgery is a feasible option in oligometastatic recurrences, such as rectal ones. Methods: Five patients with an isolated rectal recurrence infiltrating the bowel wall underwent a robotic rectosigmoid resection with totally intracorporeal colorectal anastomosis. The procedure began with retroperitoneal access to manage the vascular structures, followed by visceral resection with a minimally invasive approach. The standard steps of an en-bloc pelvic resection, including intracorporeal end-to-end anastomosis, were performed. The treatment data were evaluated. Results: The mean age of the patients was 54 years, and their mean body mass index was 30. All patients had at least one previous abdominal surgery and 60% had high-grade serous ovarian cancer at their initial diagnosis. Their mean platinum-free interval was 17.4 months. Complete secondary cytoreduction was achieved in all cases, with histopathology confirming bowel infiltration. The mean procedure duration was 294 min, with an estimated blood loss of 180 mL. No intraoperative complications occurred. The mean hospital stay was 8 days. One patient had a grade 2 postoperative complication. The mean follow-up period was 14 months, with only one patient experiencing a recurrence at the level of the abdominal wall. Conclusions: Robotic rectosigmoid resection is a viable option for complete cytoreduction in isolated recurrent ovarian cancer. [ABSTRACT FROM AUTHOR]

A unique starch-green tea extract composite was synthesized following a bio-inspired 'green' method under ultrasonication. The polar hydroxyl organofunction over the starch is coordinated with the polyphenolic phytochemicals of green tea extract to form a stable composite hydrogel. The materials were structurally analyzed through several instrumental methods such as FT-IR, UV-Vis spectroscopy, SEM, TEM and EDX. Towards biological application, the composite hydrogel was used in controlling the inflammation of adenomyosis in mice. In the in vivo design, tamoxifen was used to induce the experimental adenomyosis model in mice. After treatment, the thymus, spleen, uterine, and body weights of all the animal samples were measured. Western blotting, qRT-PCR, and immuno histochemical (IHC) staining were applied to analyze the MAPK/ERK signaling pathway protein expression in adenomyosis mice. Then, inflammatory factors expression and the myometrial infiltration were determined by qRT-PCR, ELISA, and histology examination in the uterus. The adenomyosis amelioration of starch-green tea extract composite was gained by preventing the MAPK/ERK signaling pathway including decreasing the expressions of protein and mRNA of p-p38/p38, p-JNK/JNK, and p-ERK/ERK in the uterus. The raised levels of TNF-α, IL-6, and IL-1β in adenomyosis model mice uterus and serum were also reduced after starch-green tea extract composite treatment. Starch-green tea extract composite ameliorated the adenomyosis symptoms by raising the thymus and spleen index and decreasing myometrial infiltration. [ABSTRACT FROM AUTHOR]

The current work attempted to examine the histological and immunohistochemical features of the pancreas in the southern white-breasted hedgehog (Erinaceus concolor). Five adult male individuals were used in this study. Utilizing hematoxylin and eosin as well as Masson's trichrome, staining was performed on paraffin sections of the pancreas. Immunofluorescent staining investigated the expression pattern of glucagon, insulin, somatostatin, neuropeptide Y (NY), and pancreatic polypeptide (PP). The exocrine pancreas comprised pyramidal and oval-shaped acini, exhibiting the clustering of zymogen droplets in the apical cytoplasm of acinar cells. The endocrine pancreas was distinguished as a large α islet of Langerhans and small β islets. Alpha cells were localized on the periphery of islets with an intensity of 20.6% ± 12.56. In comparison, Beta cells with 25.14% ± 5.89 intensity were gathered in the middle of the pancreatic islets. Delta cells exhibited 25.69% ± 5.13 intensity and were distributed through the islets. NY and PP cells were detected with 22.74% ± 3.25 and 16.80% ± 4.77 intensity, respectively. These cells showed prevalent distribution in the islets. In conclusion, it appears that although the pancreas of the southern white-breasted hedgehog is generally like other mammalian species, there are some species-specific features in density and dispersal of endocrine cells which can be attributed to the physiological purpose of the pancreas in this species. Future histophysiological investigations are still needed to explore the exact relationship between the histological organization of the pancreas and its function in that animal.

NUCLEAR factor E2 related factor ,CARNITINE palmitoyltransferase ,HER2 positive breast cancer ,FATTY acid oxidation ,METABOLIC reprogramming - Abstract
Metabolic reprogramming, a hallmark of tumorigenesis, involves alterations in glucose and fatty acid metabolism. Here, we investigate the role of Carnitine palmitoyl transferase 1a (Cpt1a), a key enzyme in long-chain fatty acid (LCFA) oxidation, in ErbB2-driven breast cancers. In ErbB2+ breast cancer models, ablation of Cpt1a delays tumor onset, growth, and metastasis. However, Cpt1a-deficient cells exhibit increased glucose dependency that enables survival and eventual tumor progression. Consequently, these cells exhibit heightened oxidative stress and upregulated nuclear factor erythroid 2-related factor 2 (Nrf2) activity. Inhibiting Nrf2 or silencing its expression reduces proliferation and glucose consumption in Cpt1a-deficient cells. Combining the ketogenic diet, composed of LCFAs, or an anti-ErbB2 monoclonal antibody (mAb) with Cpt1a deficiency significantly perturbs tumor growth, enhances apoptosis, and reduces lung metastasis. Using an immunocompetent model, we show that Cpt1a inhibition promotes an antitumor immune microenvironment, thereby enhancing the efficacy of anti-ErbB2 mAbs. Our findings underscore the importance of targeting fatty acid oxidation alongside HER2-targeted therapies to combat resistance in HER2+ breast cancer patients. Metabolic reprogramming is crucial in tumorigenesis, with alterations in glucose and fatty acid metabolism playing key roles. Here, the authors show that inhibiting fatty acid oxidation in HER2-driven breast cancers delays tumor growth and enhances the effectiveness of HER2-targeted therapies. [ABSTRACT FROM AUTHOR]

Simple Summary: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new surgical procedure used in the treatment of peritoneal surface malignancies (PSMs). Despite encouraging clinical results, the high costs of PIPAC and the need to repeat the treatment multiple times make the procedure difficult to sustain economically. A retrospective study was conducted in order to evaluate the cost of hospitalization for patients undergoing PIPAC treatment at a high-volume center in Italy. Currently, the Italian National Health System only partially covers the hospitals' costs. Therefore, there is an urgent need for an economical redefinition of this procedure, by creating dedicated reimbursement codes. PIPAC is a new surgical procedure and a viable treatment option for PSM patients, due to promising therapeutic outcomes, minimal invasiveness, limited surgical morbidity, and systemic toxicity side effects. However, its implementation throughout hospitals is hard to obtain due to its fragile economical sustainability. A retrospective health economic analysis was conducted in order to evaluate the cost of hospitalization for patients undergoing PIPAC treatment at Fondazione Policlinico Universitario Agostino Gemelli, IRCCS, in Rome. The average cost of a PIPAC procedure was defined based on the cost of surgery (cost of surgical material, operating room, intraperitoneal chemotherapy), hospital stay, diagnostic examinations, and drugs used during the stay. A total of 493 PIPAC procedures were performed on 222 patients with peritoneal metastases or primary peritoneal cancer from 2017 to 2023. Since the mean remuneration for each PIPAC hospitalization is €5916 and the mean expenditure per hospitalization is €6538, this results in an operating profit per PIPAC hospitalization of −€622. The reimbursement of PIPAC treatment by the Italian National Health System currently only partially covers the hospital's costs. Development of specific codes and adequate reimbursement for PIPAC by recognizing this procedure as a proper treatment for peritoneal carcinomatosis is essential. [ABSTRACT FROM AUTHOR]

- Abstract
Viral colonization was substantially reduced in banana plants that were foliar sprayed with Citosan NanoParticle, CS-NPs, solution. Banana plants treated with CS-NPs showed different levels of protection against Banana Streak Virus, BSV, compared with the untreated control plants. Banana plants treated with CS-NPs at a rate of 200 mg L
−1 , pre-inoculated with BSV, reduced the disease incidence (DI) by 75.00% and disease severity (DS) by 95.3%, compared with untreated plants. Banana plants treated with CS-NPs at a rate of 300 and 400 mg L−1 , pre and post-inoculated with BSV, showed a complete reduction in DI and DS, compared to the control. Surprisingly, the inactivation effects were no longer strong enough to prevent viral accumulation and reproduction after 24h. However, foliar spraying of CS-NPs onto banana leaves significantly reduced BSV replication by activating the plant defense and growth response. The maximum up-regulating expression level of an 18.20-fold change was attained with CS-NPs at a rate of 400 mg L−1 . Simultaneously, the mRNA accumulation of the PR-1 gene in 200- and 300 mg L−1 CS-NPs treated plants was high, with 12.12- and 10.50-relative expression fold increases, respectively, over the untreated control. Plants treated with Cs-NP showed elevated levels of reactive oxygen species (PR1 and PR2), catalase activity, and peroxidase activity. Interestingly, the NPs also markedly raised the phytohormones ABA and SA levels by 160% and 520%, respectively. [ABSTRACT FROM AUTHOR]- Published

Therapeutics that interfere with the damage/pathogen-associated molecular patterns (DAMPs/PAMPs) have evolved as promising candidates for hepatic inflammation like that occurring in non-alcoholic fatty liver disease (NAFLD). In the current study, we examined the therapeutic impact of the phosphodiesterase-1 inhibitor vinpocetine (Vinpo), alone or when combined with Lactobacillus, on hepatic abnormalities caused by a 13-week high-fat diet (HFD) and diabetes in rats. The results show that Vinpo (10 and 20 mg/kg/day) dose-dependently curbed HFD-induced elevation of liver injury parameters in serum (ALT, AST) and tissue histopathology. These effects were concordant with Vinpo's potential to ameliorate HFD-induced fibrosis (Histological fibrosis score, hydroxyproline, TGF-β
1 ) and oxidative stress (MDA, NOx) alongside restoring the antioxidant-related parameters (GSH, SOD, Nrf-2, HO-1) in the liver. Mechanistically, Vinpo attenuated the hepatocellular release of DAMPs like high mobility group box (HMGB)1 alongside lowering the overactivation of the pattern recognition receptors including, toll-like receptor (TLR)4 and receptor for advanced glycation end-products (RAGE). Consequently, there was less activation of the transcription factor nuclear factor-kappa B that lowered production of the proinflammatory cytokines TNF-α and IL-6 in Vinpo-treated HFD/diabetes rats. Compared to Vinpo treatment alone, Lactobacillus probiotics as adjunctive therapy with Vinpo significantly improved the disease-associated inflammation and oxidative stress injury, as well as the insulin resistance and lipid profile abnormalities via enhancing the restoration of the symbiotic microbiota. In conclusion, combining Vinpo and Lactobacillus probiotics may be a successful approach for limiting NAFLD in humans. [ABSTRACT FROM AUTHOR]- Published

The current research demonstrates the design, synthesis and development of a bio-inspired and green formulated nanomedicines to combat human lung cancer. The application of phytochemicals modified biocompatible nanocomposites have been an immense thrust towards biological investigations and medicinal therapeutics. In this regard, we have developed a sustainable nanomaterial having Au NPs immobilized over high surface carbonaceous support (reduced graphene oxide, RGO) bio-inspired by Arabic gum (RGO/AG/Au). The material has been meticulously characterized over FT-IR (Fourier Transformed Infra Red spectroscopy), FE-SEM (Field Emission Scanning Electron Microscopy), EDX (Energy Dispersive X ray spectroscopy), TEM (Transmission Electron Microscopy), XRD (X-ray Diffraction) and Thermo Gravimetric Analysis (TGA) techniques. Towards its bio-application, the antioxidant assay studied by DPPH radical scavenging process. IC
50 of this analysis was found as 80 µg/ml. The study was further extended in restricting the proliferation of human lung cancer cell lines, NCI-H661, NCI-H1975, NCI-H1573, and NCI-H1563 following MTT colorimetric method and the related IC50 were determined as 118, 197, 175, and 69 µg/mL respectively. The excellent anti-cancer property exhibited by RGO/AG/Au was anticipated based on the good antioxidant potential of the material. [ABSTRACT FROM AUTHOR]- Published

This study evaluated if salidroside (SAL) alleviates high-fat diet (HFD)-induced non-alcoholic fatty liver disease (NAFLD) by downregulating miR-21. Rats (n = 8/group) were treated for 12 weeks as normal diet (control/ND), ND + agmoir negative control (NC) (150 µg/kg), ND + SAL (300 mg/kg), HFD, HFD + SAL, HFD + compound C (an AMPK inhibitor) (200 ng/kg), HFD + SAL + NXT629 (a PPAR-α antagonist) (30 mg/kg), and HFD + SAL + miR-21 agomir (150 µg/kg). SAL improved glucose and insulin tolerance and preserved livers in HFD-fed rats. In ND and HFD-fed rats, SAL reduced levels of serum and hepatic lipids and the hepatic expression of SREBP1, SREBP2, fatty acid (FA) synthase, and HMGCOAR. It also activated hepatic Nrf2 and increased hepatic/muscular activity of AMPK and levels of PPARα. All effects afforded by SAL were prevented by CC, NXT629, and miR-21 agmoir. In conclusion, activation of AMPK and upregulation of PPARα mediate the anti-steatotic effect of SAL. [ABSTRACT FROM AUTHOR]

Introduction: The combination of sequential intravesical gemcitabine and docetaxel (Gem/Doce) chemotherapy has been considered a feasible option for BCG (Bacillus Calmette-Guérin) treatment in non-muscle invasive bladder cancer (NMIBC), gaining popularity during BCG shortage period. We seek to determine the efficacy of the treatment by comparing Gem/Doce induction alone vs induction with maintenance, and to evaluate the treatment outcomes of two different dosage protocols. Methods: A bi-center retrospective analysis of consecutive patients treated with Gem/Doce for NMIBC between 2018 and 2023 was performed. Baseline characteristics, risk group stratification (AUA 2020 guidelines), pathological, and surveillance reports were collected. Kaplan–Meier survival analysis was performed to detect Recurrence-free survival (RFS). Results: Overall, 83 patients (68 males, 15 females) with a median age of 73 (IQR 66–79), and a median follow-up time of 18 months (IQR 9–25), were included. Forty-one had an intermediate-risk disease (49%) and 42 had a high-risk disease (51%). Thirty-seven patients (45%) had a recurrence; 19 (23%) had a high-grade recurrence. RFS of Gem/Doce induction-only vs induction + maintenance was at 6 months 88% vs 100%, at 12 months 71% vs 97%, at 18 months 57% vs 91%, and at 24 months 31% vs 87%, respectively (log-rank, p < 0.0001). Patients who received 2 g Gemcitabine with Docetaxel had better RFS for all-grade recurrences (log-rank, p = 0.017). However, no difference was found for high-grade recurrences. Conclusion: Gem/Doce induction with maintenance resulted in significantly better RFS than induction-only. Combining 2 g gemcitabine with docetaxel resulted in better RFS for all-grade but not for high-grade recurrences. Further prospective trials are necessary to validate our results.

Background: Applying cognitive defusion techniques to enduring psychotic symptoms, such as delusions, presents both a challenge and a promising opportunity for psychiatric nurses to manage delusions among schizophrenia clients. Objective: This study aimed to examine the impact of cognitive defusion techniques on psychological flexibility, mindful awareness, cognitive fusion, and the believability of delusions in schizophrenia clients. Methodology: This study used a single-blind, parallel-arm Randomized Controlled Trial design. Over five weeks, 70 clients with schizophrenia were randomized to either the cognitive defusion intervention group (n = 35) or the control group (n = 35). Findings: The participants showed significant reductions in the believability of delusions, cognitive fusion, and psychological inflexibility immediately after the intervention and at follow-up. Notable enhancements were observed in cognitive defusion and mindfulness awareness abilities. Conclusion: Cognitive defusion techniques positively affect schizophrenia clients who struggle with persistent delusional beliefs. This underscores the importance of further investigating this approach to decrease the intensity of delusions as part of a comprehensive therapeutic intervention. Psychiatric nurses must receive training in "cognitive defusion skills" to aid schizophrenia clients in becoming more aware of their emotions and modifying their coping strategies for delusional beliefs. On August 3, 2023, the research was retrospectively registered under the reference number NCT05759091 as a randomized clinical trial. Clinical trial registration: https://classic.clinicaltrials.gov/ct2/show/NCT05759091, identifier NCT05759091. [ABSTRACT FROM AUTHOR]

Identifying factors that influence age-related cognitive decline is crucial, given its severe personal and societal impacts. However, studying aging in human or animal models is challenging due to the significant variability in aging processes among individuals. Additionally, longitudinal and cross-sectional studies often produce differing results. In this context, home-cage-based behavioral analysis over lifespans has emerged as a significant method in recent years. This study aimed to explore how prior experience affects cognitive performance in mice of various age groups (4, 12, and 22 months) using a home-cage-based touchscreen test battery. In this automated system, group-housed, ID-chipped mice primarily obtain their food during task performance throughout the day, motivated by their own initiative, without being subjected to food deprivation. Spatial working memory and attention were evaluated using the trial unique non-matching to location (TUNL) and the five-choice serial reaction time task (5-CSRTT), respectively. The same set of mice learned both of these demanding tasks. While signs of cognitive decline were already apparent in middle-aged mice, older mice exhibited poorer performance in both tasks. Mice at both 12 and 22 months displayed an increase in perseverance and a decrease in the percentage of correct responses in the TUNL test compared to the 4-monthold mice. Furthermore, during the 5-CSRTT, they exhibited higher rates of omissions and premature responses compared to their younger counterparts. Additionally, the correct response rate in 22-month-old mice was lower than that of the 4-month-old ones. However, mice that had undergone cognitive training at 4 months maintained high-performance levels when re-tested at 12 months, showing an increase in correct responses during TUNL testing compared to their untrained controls. In the 5-CSRTT, previously trained mice demonstrated higher correct response rates, fewer omissions, and reduced premature responses compared to naive control mice. Notably, even when assessed on a visual discrimination and behavioral flexibility task at 22 months, experienced mice outperformed naive 4-month-old mice. These findings highlight the advantages of early-life cognitive training and suggest that its benefits extend beyond the cognitive domains primarily targeted during early training. The success of this study was significantly aided by the fully automated home-cage-based testing system, which allows for high throughput with minimal human intervention. [ABSTRACT FROM AUTHOR]

Sexual reproduction is a crucial process for reef building coral populations to maximize genetic diversity and recover from large scale disturbances. Mass spawning events by Acropora species represent critical opportunities for populations to persist, and a process that is increasingly exploited to actively restore degraded reefs. However, the timing and predictive capacity of coral spawning throughout the broad thermal and environmental regime of the Red Sea – a region also undergoing significant development and active reef restoration – remains patchy. We, therefore, conducted three parallel reef surveys in the central Red Sea (Al-Fahal Reef, Thuwal - Saudi Arabia) and the eastern (Shushah Island - Saudi Arabia) and western (Hurghada – Egypt) coast of the northern Red Sea. Surveys assessed the gravidity of gonads, spawning timing, alignment with the lunar cycle of 21 Acropora spp. (total n= 572 colonies) around the full moons of April and May 2023. Consistent with past observations, synchronous spawning was observed for Acropora spp. in both the central and northern Red Sea during April and May, respectively. Interestingly, corals spawned on the full moon in both Shushah and Thuwal sites. In contrast, corals in Hurghada were independent of the lunar cycle and spawned 7-9 nights before the full moon in May. By integrating our 2023 observations with the historical spawning events in Hurghada and Thuwal (2002-2022), we found that the deviation of spawning timing from the full moon day was correlated with absolute Sea Surface Temperature (SST) (earlier spawning before the full moon day, lower SST) and warming rate (earlier spawning, more rapid warming) in 6- weeks prior to spawning. As such, temperature pattern is likely one of the primary factors governing gamete release, among other factors, that likely influence spawning day within the lunar month. These correlations between SST metrics and spawning timing suggest a potential framework to predict future Acropora spp. spawning dates. Our observations demonstrate the importance of parallel efforts across borders to collect critical data needed to inform management strategies aimed at conserving and restoring coral reefs in this ecologically diverse region.

- Abstract
A lot of research has been done on using natural items as diabetes treatment. The molecular docking study was conducted to evaluate the inhibitory activities of urolithin A against α-amylase, α-glucosidase, and aldose reductase. The molecular docking calculations indicated the probable interactions and the characteristics of these contacts at an atomic level. The results of the docking calculations showed the docking score of urolithin A against α-amylase was −5.169 kcal/mol. This value for α-glucosidase and aldose reductase was −3.657 kcal/mol and −7.635 kcal/mol, respectively. In general, the outcomes of the docking calculations revealed that urolithin A can construct several hydrogen bonds and hydrophobic contacts with the assessed enzymes and reduces their activities considerably. The properties of urolithin against common human breast cancer cell lines, i.e., SkBr3, MDA-MB-231, MCF-7, Hs578T, Evsa-T, BT-549, AU565 and 600MPE were evaluated. The IC50 of the urolithin was 400, 443, 392, 418, 397, 530, 566 and 551 against SkBr3, MDA-MB-231, MCF-7, Hs578T, Evsa-T, BT-549, AU565 and 600MPE, respectively. After doing the clinical trial studies, the recent molecule may be used as an anti-breast cancer supplement in humans. IC50 values of urolithin A on α-amylase, α-glucosidase, and aldose reductase enzymes were obtained at 16.14, 1.06 and 98.73 µM, respectively. [ABSTRACT FROM AUTHOR]

The current work has been dedicated to the research studies on the development of green formulated nanomedicines to combat the hepatocellular carcinoma or liver cancer. Plant derived biogenic nanocomposite has been a major focus these days in the biological studies. So, herein we are prompted to develop a biocompatible and biodegradable carbonaceous nanocomposite where silver nanoparticles (Ag NPs) have been fabricated over the reduced graphene oxide (RGO) bio-inspired by Mentha spicata flower extract (RGO/M.S./Ag). The material has been methodically analyzed by advanced techniques like Fourier Transform Infrared Spectroscopy (FT-IR), Field Emission Scanning Electron Microscopes (FE-SEM), Energy Dispersive X-ray Spectroscopy (EDX), Transmission Electron Microscopy (TEM) and X-ray diffraction (XRD). Thereafter, the material was involved in the estimation of antioxidant properties by (2,2-Diphenyl-1-picrylhydrazyl) DPPH radical scavenging method. The biological evaluation was further comprehended in the cytotoxic studies against the HepG2 (human hepatoma) liver cancer cell line in-vitro following Multi-Table Tournament (MTT) process. Interestingly, the material afforded % toxicity over the malignant cell line that reduced dose-dependently with its concentration. The inertness of RGO/M.S./Ag material towards normal cells were also verified over the CHO (Chinese hamster ovary) human normal cell line. The obtained results advocate the RGO/M.S./Ag nanocomposite to be a potential candidate against liver cancer. However, further studies are required to study in vivo for understanding the molecular mechanisms. [ABSTRACT FROM AUTHOR]

This article discusses the recurrence rates in transnasal transsphenoidal surgeries for the gross total resection of pituitary adenoma. The study compared the recurrence rates and time to recurrence in patients who underwent different levels of pseudocapsule dissection during the surgery. The results showed that the extent of pseudocapsule dissection did not significantly impact the recurrence rate or time to recurrence. The study suggests that complete pseudocapsule dissection may not be necessary as long as gross total resection is achieved. Further analysis will examine these differences in functional and nonfunctional tumors, as well as complication rates. [Extracted from the article]

Introduction: Digital pathology artificial intelligence (AI) platforms have the capacity to improve over time through "deep machine learning." We have previously reported on the accuracy of peripheral white blood cell (WBC) differential and blast identification by Techcyte (Techcyte, Inc., Orem, UT, USA), a digital scanner‐agnostic web‐based system for blood film reporting. The aim of the current study was to compare AI protocols released over time to assess improvement in cell identification. Methods: WBC differentials were performed using Techcyte's online AI software on the same 124 digitized abnormal peripheral blood films (including 64 acute and 22 chronic leukaemias) in 2019 (AI1), 2020 (AI2), and 2022 (AI3), with no reassignment by a morphologist at any time point. AI results were correlated to the "gold standard" of manual microscopy, and comparison of Lin's concordance coefficients (LCC) and sensitivity and specificity of blast identification were used to determine the superior AI version. Results: AI correlations (r) with manual microscopy for individual cell types ranged from 0.50–0.90 (AI1), 0.66–0.86 (AI2) and 0.71–0.91 (AI3). AI3 concordance with manual microscopy was significantly improved compared to AI1 for identification of neutrophils (LCC AI3 = 0.86 vs. AI1 = 0.77, p = 0.03), total granulocytes (LCC AI3 = 0.92 vs. AI1 = 0.82, p = 0.0008), immature granulocytes (LCC AI3 = 0.67 vs. AI1 = 0.38, p = 0.0014), and promyelocytes (LCC AI3 = 0.53 vs. AI1 = 0.16, p = 0.0008). Sensitivity for blast identification (n = 65 slides) improved from 97% (AI1), to 98% (AI2), to 100% (AI3), while blast specificity decreased from 24% (AI1), to 14% (AI2) to 12% (AI3). Conclusion: Techcyte AI has shown significant improvement in cell identification over time and maintains high sensitivity for blast identification in malignant films. [ABSTRACT FROM AUTHOR]

One of the main goals of medicinal chemistry in recent years has been the development of new enzyme inhibitors and anti-cancer medicines. The isokaempferide' ability to inhibit the enzymes urease, elastase, and collagenase were also studied. The results showed that isokaempferide was the most effective compound against the assigned enzymes, with IC50 values of 23.05 µM for elastase, 12.83 µM for urease, and 33.62 µM for collagenase respectively. It should be emphasized that natural compound was more effective at inhibiting some enzymes. Additionally, the compound was tested for their anti-cancer properties using colon, lung, breast cancer cell lines. The chemical activities of isokaempferide against urease, collagenase, and elastase were investigated utilizing the molecular docking study. The anti-cancer activities of the compound were evaluated against lung cancer cells such as SPC-A-1, SK-LU-1, 95D, breast cancer cells like MCF7, Hs 578Bst, Hs 319. T, and UACC-3133 cell lines, and colon cancer cell lines like CL40, SW1417, LS1034, and SW480. The chemical activities of isokaempferide against some of the expressed surface receptor proteins (EGFR, estrogen receptor, CD47, progesterone receptor, folate receptor, CD44, HER2, CD155, CXCR4, CD97, and endothelin receptor) in the mentioned cell lines were assessed using the molecular docking calculations. The results showed the probable interactions and their characteristics at an atomic level. The docking scores revealed that isokaempferide has a strong binding affinity to the enzymes and proteins. In addition, the compound formed powerful contact with the enzymes and receptors. Thus, isokaempferide could be potential inhibitor for enzymes and cancer cells. [ABSTRACT FROM AUTHOR]

This report expresses a sustainable methodology for the in situ synthesis of Ag nanoparticles (NPs) adorned carboxymethyl lignin (CML) functionalized Fe
3 O4 nanocomposite (Fe3 O4 @CML/Ag) and its subsequent chemical and biological applications. Structural and physicochemical features of such novel material was evaluated through a number of analytical techniques like FT-IR, FE-SEM, TEM, EDS, XRD, ICP and VSM. The nanomaterial was a competent catalyst towards the N-acylation of diverse amines using acetic anhydride at solvent-free conditions. The material was isolated by magnet and reused for 8 consecutive times. Furthermore, the material was employed in the biological evaluation of anti-oxidant properties by DPPH method as well as the anticancer studies of against HT-29 and Caco-2 colon cell lines following MTT method. The DPPH assay afforded a significant IC50 value that suggested the material to have good anticancer properties. Interestingly, % cell viability of the malignant cell lines was found to decrease dose-dependently over Fe3 O4 @NaLS/Ag nanocomposite. MTT assay afforded the corresponding IC50 values to be 395.4 μg/ml and 287.3 μg/ml respectively against the two cell lines. The absorbance rate was evaluated at 545 nm, which represented toxicity on normal cell line (CHO) even up to 2000 μg/mL. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Purpose: The International Atomic Energy Agency (IAEA) has developed a harmonized quality control (QC) protocol for performance evaluation and comparison of diagnostic radiology facilities in Africa. This study analyzes QC data on X-ray, computed tomography (CT), mammography and fluoroscopy equipment provided by African countries that applied the established QC protocol for pilot implementation of a regional quality assurance (QA) program. Methods: Total of 108 medical imaging equipment comprising 51 X-ray, 23 CT, 20 mammography and 14 fluoroscopy systems in use at 51 diagnostic radiology centres in 5 African countries were considered. All performance tests were conducted in accordance with the harmonized African protocol, and the data were validated and analyzed using MS Excel 365 through visual summaries, trends and patterns. Results from the analysis were benchmarked against acceptance criteria of the protocol. Results: Results from the performance measurements for X-ray machines include half value layer (HVL), beam perpendicularity, output, timer and kVp accuracies, while CT performance measurements comprised uniformity and accuracy, image noise, dosimetry and laser alignment. Mammography data include collimation accuracy, kV and timer accuracy, radiation output reproducibility and mean glandular dose, and fluoroscopy data cover automatic exposure control (AEC) and resolution. Out-of-tolerance data were conspicuous in some X-ray and CT machines, for which investigation was recommended. Conclusion: The study has produced promising results, showed general performance of the pilot imaging equipment and identified abnormalities that would otherwise not have been detected. A good basis has been set for implementation of the harmonized protocol on a wider scale in Africa. [ABSTRACT FROM AUTHOR]

Natural compounds, such as carotenoids, flavonoids, anthocyanins, or terpenoids, are physiologically active components found in plants (pigments), often known as phytochemicals or phytonutrients. The in vitro cytotoxic and anticolon cancer effects of biologically bavachin, bavachinin, artepillin C, and aromadendrin compounds against SW48, SNU‐C1, COLO 205, RKO, LS411N, and SW1417 cancer cell lines were assessed. Results of enzymes and antibacterial, antifungal were in level of micromolar that is good impacts. These natural compounds may be antidiabetic, anticancer, and antibacterial candidates for drug design. IC50 results were obtained between 14–19 and 5–119 µM for α‐amylase and α‐glucosidase, respectively. Good inhibitor Bavachinin was detected for both enzymes (IC50 for α‐amylase: 14.37 µM and IC50 for α‐glucosidase: 5.27 µM). The chemical activities of aromadendrin, artepillin C, bavachin, and bavachinin against pancreatic α‐amylase and α‐glucosidase were assessed by conducting the molecular docking study. The chemical activities of aromadendrin, artepillin C, bavachin, and bavachinin against some of the expressed surface receptor proteins (CD44, CD47, CXCR4, EGFR, folate receptor, HER2, and endothelin receptor) in the mentioned cell lines were investigated using the molecular docking calculations. The results illustrated the atomic‐level properties and potential interactions. These chemicals have high binding affinities to the enzymes and proteins, according to the docking scores. In addition, the compounds formed strong contacts with the enzymes and receptors. Thus, these compounds could be potential inhibitors for enzymes and cancer cells. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Robotic-assisted radical cystectomy (RARC) offers decreased blood loss during surgery, shorter hospital length of stay, and lower risk for thromboembolic events without hindering oncological outcomes. Cutaneous ureterostomies (UCS) are a seldom utilized diversion that can be a suitable alternative for a selected group of patients with competing co-morbidities and limited life expectancy. Objective: To describe operative and perioperative characteristics as well as oncological outcomes for patients that underwent RARC + UCS. Methods: Patients that underwent RARC + UCS during 2013–2023 in 3 centers (EU = 2, US = 1) were identified in a prospectively maintained database. Baseline characteristics, pathological, and oncological outcomes were analyzed. Descriptive statistics and survival analysis were performed using R language version 4.3.1. Results: Sixty-nine patients were included. The median age was 77 years (IQR 70–80) and the median follow-up time was 11 months (IQR 4–20). Ten patients were ASA 4 (14.5%). Nine patients underwent palliative cystectomy (13%). The median operation time was 241 min (IQR 202–290), and the median hospital stay was 8 days (IQR 6–11). The 30-day complication rate was 55.1% (grade ≥ 3a was 14.4%), and the 30-day readmission rate was 17.4%. Eleven patients developed metastatic recurrence (15.9%), and 14 patients (20.2%) died during the follow-up period. Overall survival at 6, 12, and 24 months was 84%, 81%, and 73%, respectively. Conclusions: RARC + UCS may offer lower complication and readmission rates without the need to perform enteric anastomosis, it can be considered in a selected group of patients with competing co-morbidities, or limited life expectancy. Larger prospective studies are necessary to validate these results. [ABSTRACT FROM AUTHOR]

Background: This study aims to compare the performance of intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) in treating laryngeal cancer. Method: In this retrospective dosimetric study, 15 patients diagnosed with locally advanced laryngeal cancer (LALC) were selected. The dosimetric performance of the two techniques was analyzed using 6 MV X-rays, based on dose-volume histograms for primary and boost planning target volumes (PTV
p and PTVb , respectively), relevant organs at risk (OARs), mean Dose (Dmean ), maximum Dose (Dmax ), 95% Dose (D95 ), 2% Dose (D2% ), 5% Dose (D5% ), monitor units per segment (MU/segment), number of MU/cGy, treatment delivery time, along with conformity and homogeneity indices. Results: Both techniques were able to achieve favorable equivalent uniform doses and low doses to OARs. The average total number of monitor units for IMRT was significantly greater than that for VMAT (1724.5 ± 249.5 and 475.3 ± 47.0, respectively for PTVp and 601.4 ± 81.7 and 458.0 ± 62.6, respectively for PTVb). The modulation factor (MU/cGy) of IMRT was significantly greater than that for VMAT for both the primary and the boost phases. The mean treatment delivery time for all cases of IMRT was significantly longer than that of VMAT. Conclusion: The primary distinction between IMRT and VMAT in the treatment of LALC is that VMAT requires significantly fewer monitor units (one-third) compared with IMRT. This reduction contributes to a decrease in treatment time, which in turn positively impacts patient comfort and the accuracy of treatment. [ABSTRACT FROM AUTHOR]- Published

We herein demonstrate the biogenic nano-architechtonics of gold nanoparticles template over chitosan/gelatin mixed hydrogel having excellent reducing ability. The two biopolymers, i.e., chitosan and gelatin also had the capacity to stabilize as-synthesized Au NPs. Physicochemical and structural features of the nanocomposite biomaterial was assessed by several techniques like FT-IR, SEM, TEM, EDX and XRD. TEM study revealed the mean diameter of the spherical shaped Au NPs/CS-Gel material was in the range of 10–15 nm. Thereafter, the Au NPs/CS-Gel bio-composite material was exploited in the study of cytotoxicity and anti-leukemia effects against diverse leukemia cell lines like acute myeloid leukemia (32D-FLT3-ITD and Human HL-60/vcr), acute lymphoblastic leukemia (MOLT-3 and TALL-104), and acute T cell leukemia (Jurkat, Clone E6-1 and J.RT3-T3.5) in situ. Interestingly, the nano-drug could resist significantly against those cell lines in a time and concentration-dependent manner, assessed by MTT method. The corresponding IC
50 values of the bio-composite were 341, 500, 417, 407, 389, and 500 µg/mL respectively against the cell lines. [ABSTRACT FROM AUTHOR]- Published

The present study investigates experimentally the influence of a movable air jet impingement on the characteristics of heat transfer over a flat plate. The experiments are conducted with a nozzle translation velocity ( V n ) of 200 mm min
−1 , a Reynolds number (Re) of 24,000, and a nozzle-to-plate distance ratio (H/D) of 1, 3, 5, and 7. The characteristics of heat transfer on a flat surface due to the use of a movable air nozzle are compared with those of a fixed one using an IR camera. The local Nusselt number (Nu), average Nusselt number ( Nu ¯ ), heat transfer uniformity index (HTU), and heat transfer uniformity (U) are investigated. The results demonstrate that the movable nozzle is more effective than the fixed one for reducing the temperature variation over the heating surface, leading to more heat transfer uniformity. The maximum values of both the Nu and Nu ¯ are obtained at a H/D of 1. The U that is improved for the movable nozzle when compared to the fixed nozzle is significantly influenced by the H/D. The maximum values of U are 85 and 72% at a H/D of 7 for the movable and fixed nozzles, respectively. The movable nozzle improves the uniformity of heat transfer more than the fixed one by 75, 42, 39, and 43% at a H/D of 1, 3, 5, and 7, respectively. Moreover, a comparison between the results of the Nu ¯ of the present work and those of previous studies is conducted. [ABSTRACT FROM AUTHOR]- Published

Introduction: Gastric cancer with peritoneal metastasis (GCPM) has an unfavourable prognosis. Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) and pressurized intraperitoneal aerosol chemotherapy (PIPAC) are promising treatment options that have been shown to improve survival. The aim of this study was to assess the impact of different treatments such as systemic chemotherapy, systemic chemotherapy + PIPAC, and CRS + HIPEC in patients with GCPM. Material and methods: This single-centre retrospective study included 82 patients with GCPM treated between January 2016 and June 2021. After first-line chemotherapy, depending on disease response and burden, the patients were divided into three treatment groups: chemotherapy alone, chemotherapy + PIPAC, and CRS + HIPEC. The primary outcome was overall survival (OS) from diagnosis, which was compared among the treatment groups. Results: Thirty-seven (45.1%) patients were administered systemic chemotherapy alone, 25 (30.4%) received chemotherapy + PIPAC, and 20 (24.4%) underwent CRS + HIPEC. The CRS + HIPEC group had better OS (median 24 months) than the PIPAC group (15 months, p = 0.01) and chemotherapy group (5 months, p = 0.0001). Following CRS + HIPEC, the postoperative grade 3–4 complication rate was 25%, and no postoperative in-hospital deaths occurred. The median disease-free survival (DFS) was 12 months. Multivariate analysis identified peritoneal carcinomatosis index (PCI) > 7 as an independent predictor of worse DFS. No independent predictors of OS were identified. Conclusion: Among patients with GCPM, we identified a highly selected population with oligometastatic disease. In this group, CRS + HIPEC provided a significant survival advantage with an acceptable major complication rate compared with other available therapies (systemic chemotherapy alone or in combination with PIPAC).

Diabetes mellitus has a high prevalence rate and it has been deemed a severe chronic metabolic disorder with long-term complications. This research aimed to identify compounds that could potentially inhibit the vital metabolic enzyme α-glucosidase and thereby exert an anti-hyperglycemic effect. The main goal was to establish an effective approach to control diabetes. To proceed with this study, a series of novel coumarin-derived thiosemicarbazones 3a–3m was synthesized and examined using a variety of spectroscopic methods. Moreover, all the compounds were subjected to α-glucosidase inhibition bioassay to evaluate their antidiabetic potential. Fortunately, all the compounds exhibited several folds potent α-glucosidase inhibitory activities with IC
50 values ranging from 2.33 to 22.11 µM, in comparison to the standard drug acarbose (IC50 = 873.34 ± 1.67 µM). The kinetic studies of compound 3c displayed concentration-dependent inhibition. Furthermore, the binding modes of these molecules were elucidated through a molecular docking strategy which depicted that the thiosemicarbazide moiety of these molecules plays a significant role in the interaction with different residues of the α-glucosidase enzyme. However, their conformational difference is responsible for their varied inhibitory potential. The molecular dynamics simulations suggested that the top-ranked compounds (3c, 3g and 3i) have a substantial effect on the protein dynamics which alter the protein function and have stable attachment in the protein active pocket. The findings suggest that these molecules have the potential to be investigated further as novel antidiabetic medications. [ABSTRACT FROM AUTHOR]- Published

These biofertilizers, based on microorganisms, offer numerous benefits such as enhanced nutrient acquisition (N, P, and K), production of hydrogen cyanide (HCN), and control of pathogens through induced systematic resistance. Additionally, they promote the production of phytohormones, siderophore, vitamins, protective enzymes, and antibiotics, further contributing to soil sustainability and optimal agricultural productivity. The escalating generation of organic waste from farm operations poses significant threats to the environment and soil fertility. Simultaneously, the excessive utilization of chemical fertilizers to achieve high crop yields results in detrimental impacts on soil structure and fertility. To address these challenges, a sustainable agriculture system that ensures enhanced soil fertility and minimal ecological impact is imperative. Microbial composts, developed by incorporating characterized plant-growth-promoting bacteria or fungal strains into compost derived from agricultural waste, offer a promising solution. These biofertilizers, with selected microbial strains capable of thriving in compost, offer an eco-friendly, cost-effective, and sustainable alternative for agricultural practices. In this review article, we explore the potential of microbial composts as a viable strategy for improving plant growth and environmental safety. By harnessing the benefits of microorganisms in compost, we can pave the way for sustainable agriculture and foster a healthier relationship between soil, plants, and the environment.

Objectives: To compare the safety and efficacy of oral apixaban with that of injectable enoxaparin after robot‐assisted radical cystectomy (RARC) for venous thromboembolism (VTE) thromboprophylaxis. Materials and Methods: We conducted a retrospective review of prospectively collected data for all RARC patients treated at our tertiary care centre between 2018 and 2022. The study included two groups: patients who were subject to a prospectively implemented protocol from October 2021 to the present, comprising a 21‐day postoperative course of apixaban 2.5 mg twice daily after discharge, and patients treated prior to October 2021 who received enoxaparin 40 mg daily. Baseline demographics and clinical characteristics, such as VTE (defined as deep vein thrombosis and pulmonary embolism), were analysed. The primary outcome was incidence of symptomatic VTE confirmed with definitive imaging within 90 days of RARC. Secondary outcomes included major bleeding, complications, readmission, and mortality within 30 days postoperatively. Descriptive statistics included baseline patient characteristics, operative information and complications. Differences in baseline characteristics and postoperative data were compared between groups. Multivariate logistic regression was used to determine associations between variables and the primary outcome. Results: A total of 124 patients received apixaban and 250 patients received enoxaparin prophylaxis. Ten patients (2.7%) experienced a VTE within 90 days postoperatively (two [1.6%] apixaban group vs eight [3.2%] enoxaparin group; P = 0.5). After patient stratification into European Association of Urology risk groups, no statistically significant difference in VTE rates was seen between groups in the apixaban (2.7% high‐ + intermediate‐risk group vs 1.1% low‐risk group; P = 0.5) and enoxaparin cohorts (4.3% high‐ + intermediate‐risk group vs 2.5% low‐risk group; P = 0.5). On multivariate logistic regression, no variables were associated with the development of the primary outcome. Conclusion: Prophylaxis with apixaban and enoxaparin showed no statistically significant differences in VTE rates among RARC patients. Apixaban appears to be safe and effective for VTE prophylaxis after RARC. [ABSTRACT FROM AUTHOR]

Thermochemical sorption energy storage (TSES) is the most recent thermal energy storage technology and has been proposed as a promising solution to reduce the mismatch between the energy supply and demand by storing energy for months in form of chemical bonds and restore it in form of synthesis chemical reaction. Compared with sensible/latent thermal energy processes, TSES system has major advantages, including a high energy storage capacity/density and the possibility of long-term energy retention with negligible heat loss. Therefore, a solid–gas thermochemical sorption battery is established and investigated utilizing a composite working pair of MgSO
4 –H2 O based on room temperature expanded graphite (RTEG), treated with sulfuric acid (H2 SO4 ) and ammonium persulfate ((NH4 )2 S2 O8 ) as a porous additive. The experimental results showed that energy storage density and sorption efficiency increase with the increment of charging temperature or decreasing of discharging temperature at a certain ambient temperature. Under experimental conditions, energy density ranged from 31.7 to 908.8 kJ/kg (corresponding to volume energy density from 11.7 to 335.8 MJ/m3 ), while sorption energy efficiency ranged from 28.3 to 79.1%. The highest values were obtained when charging, condensation, and discharging temperatures were 95, 20, and 15 °C, respectively. The maximum thermal efficiency was 21.1% at charging/discharging temperature of 95/15 °C with sensible to sorption heat ratio of 3:1. [ABSTRACT FROM AUTHOR]- Published

Background: Egypt has witnessed elevated incidence rates of multidrug-resistant Klebsiella pneumoniae infections in intensive care units (ICUs). The treatment of these infections is becoming more challenging whilst colistin-carbapenem-resistant K. pneumoniae is upsurging. Due to the insufficiently available data on the genomic features of colistin-resistant K. pneumoniae in Egypt, it was important to fill in the gap and explore the genomic characteristics, as well as the antimicrobial resistance, the virulence determinants, and the molecular mechanisms of colistin resistance in such a lethal pathogen. Methods: Seventeen colistin-resistant clinical K. pneumoniae isolates were collected from ICUs in Alexandria, Egypt in a 6-month period in 2020. Colistin resistance was phenotypically detected by modified rapid polymyxin Nordmann/Poirel and broth microdilution techniques. The isolates susceptibility to 20 antimicrobials was determined using Kirby-Bauer disk diffusion method. Whole genome sequencing and bioinformatic analysis were employed for exploring the virulome, resistome, and the genetic basis of colistin resistance mechanisms. Results: Out of the tested K. pneumoniae isolates, 82.35% were extensively drug-resistant and 17.65% were multidrug-resistant. Promising susceptibility levels towards tigecycline (88.24%) and doxycycline (52.94%) were detected. Population structure analysis revealed seven sequence types (ST) and K-types: ST383-K30, ST147-K64, ST17-K25, ST111-K63, ST11-K15, ST14-K2, and ST525-K45. Virulome analysis revealed yersiniabactin, aerobactin, and salmochelin siderophore systems in ˃ 50% of the population. Hypervirulence biomarkers, iucA (52.94%) and rmpA/A2 (5.88%) were detected. Extended-spectrum β-lactamase- and carbapenemase-producers accounted for 94.12% of the population, with bla
CTX-M-15 , blaNDM-5, and blaOXA-48 reaching 64.71%, 82.35%, and 82.35%, respectively. Chromosomal alterations in mgrB (82.35%) were the most prevailing colistin resistance-associated genetic change followed by deleterious mutations in ArnT (23.53%, L54H and G164S), PmrA (11.76%, G53V and D86E), PmrB (11.76%, T89P and T134P), PmrC (11.76%, S257L), PhoQ (5.88%, L322Q and Q435H), and ArnB (5.88%, G47D) along with the acquisition of mcr-1.1 by a single isolate of ST525. Conclusions: In this study, we present the genotypic colistin resistance mechanisms in K. pneumoniae isolated in Egypt. More effective antibiotic stewardship protocols must be implemented by Egyptian health authorities to restrain this hazard and safeguard the future utility of colistin. This is the first characterization of a complete sequence of mcr-1.1-bearing IncHI2/IncHI2A plasmid recovered from K. pneumoniae clinical isolate belonging to the emerging high-risk clone ST525.

Introduction: One of the plants that has long been considered by humans is Equisetum arvense L. Equisetum arvense L is now recommended for external use to heal wounds and for internal use to relieve urinary tract and prostate disorders. In the current study, the antioxidant, cytotoxicity, and anti-human lung cancer properties of Equisetum arvense were investigated in in vitro conditions. Material and methods: Total phenolic content, total flavonoid content, radical scavenging activity, and ferrous ion chelating were assessed to evaluate the antioxidant activity. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was chosen to investigate anticancer activity of the plant extract. Results: The plant extract scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH) as a free radical with an IC50 of 12.3 ±0.7 µg/ml better than positive controls. The plant was also rich in phenolic compounds with an amount of 396.2 ±3.2 mg GAE/g for total phenolic content. In the MTT assay, human colorectal carcinoma (HCT-8 [HRT-18], Ramos.2G6.4C10, HT-29, and HCT 116) and normal cell lines (HUVEC) were used to study the cytotoxicity and anticancer potential of Equisetum arvense L against human colorectal cancer. Conclusions: The cell viability of Equisetum arvense L was very low against human colorectal carcinoma cell lines without any cytotoxicity towards the normal (HUVEC) cell line. The best anti-human colorectal carcinoma properties of Equisetum arvense L against the above cell lines were observed in the case of the HT 29 cell line. [ABSTRACT FROM AUTHOR]

Phthalates are widely distributed in our environment due to their usage in many industries, especially in plastic production, which has become an essential part of daily life. This investigation aimed to assess the potential remedial influence of lutein, a naturally occurring carotenoid, on phthalate-triggered damage to the liver and kidneys. When di-(2-ethylhexyl) phthalate (DEHP) was administered to male albino rats over sixty straight days at a dosage of 200 mg/kg body weight, it resulted in a significant increase in the serum activity of liver enzymes (AST, ALT, and GGT), alpha-fetoprotein, creatinine, and cystatin-C, as well as disruptions in the serum protein profile. In addition, intoxication with DEHP affected hepato-renal tissues' redox balance. It increased the content of some proinflammatory cytokines, nuclear factor kappa B (Nf-κB), and apoptotic marker (caspase-3); likewise, DEHP-induced toxicity and decreased the level of anti-apoptotic protein (Bcl-2) in these tissues. Lutein administration at a dose level of 40 mg/kg b.w efficiently facilitated the changes in serum biochemical constituents, hepato-renal oxidative disturbance, and inflammatory, apoptotic, and histopathological alterations induced by DEHP intoxication. In conclusion, it can be presumed that lutein is protective as a natural carotenoid against DEHP toxicity. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Among people with bipolar disorders, there are high rates of impulsivity and suicide attempts. Efforts to reduce suicide are hindered by the lack of conclusive evidence on interventional programs for those at risk. Thus, this work evaluated the efficacy of acceptance and commitment therapy on impulsivity and suicidality among bipolar clients. Methods: In a randomized controlled trial, 30 eligible clients with bipolar disorders were given Acceptance and Commitment Therapy, and 30 eligible clients for the control group were chosen randomly at a 1:1 ratio using Research Randomizer version 4.0. Clients completed the Acceptance and Action Questionnaire II, the Short Arabic Version of the Impulsivity Behavior Scale, and the Arabic Version of the Beck Scale for Suicide Ideation. Results: It can be observed that there was a statistically significant decrement in the mean scores of psychological inflexibility among the study group between baseline value (T0), posttest measurement (T1), and post-two-month follow-up (T2), from 32.91 SD (6.03) to 23.06 SD (6.22) post and 26.83 SD (3.49) post-two months, with an effect size of 0.846 (P < 0.001), compared to the control group, which revealed an increase in the mean score. The overall impulsivity among the study group between T0, T1, and T2 was 61.27 SD (4.57) to 46.83 SD (4.47) post- and 43.0 SD (5.30) post-two months, with an effect size of 0.906 (P < 0.001). Compared to the control group, which revealed a relative increase in the mean impulsivity score at the post- and post-two-month intervals, the Arabic Versions of the Beck Scale for Suicide Ideation Scale mean score before the intervention was 16.33 SD (6.08), then the post was 7.23 SD (4.72), and the post-two-month mean was 10.13 SD (5.49) with an effect size of 0.878 (P < 0.001) among the study group. On the other hand, mean scores of “suicide ideation” among clients in the control group increased posttest and nearly returned to the same value after two months. Conclusion: For bipolar clients suffering from suicidal thoughts and impulsive behaviors, acceptance and commitment therapy, an emerging third-wave behavior therapy, is an effective intervention. Trial registration: The study was registered retrospectively with reference number NCT05693389 on 23/1/2023, available at: . [ABSTRACT FROM AUTHOR]

A novel coronavirus, severe acute respiratory syndrome coronavirus-2, was isolated from patients' lower respiratory tracts in December 2019. As of May 19, 2021, there were over 33 million reported infections and almost 600,000 deaths in the United States. The infection, coronavirus disease-19 (COVID-19), can lead to cytokine storm, with elevations in interleukin-6 (IL-6), IL-10, tumor necrosis factor-α, nuclear factor-kappaB (NF-kappaB), and glutathione reductase. NF-kappaB activation is necessary for further transcription of other pro-inflammatory markers. Glutathione may play a role in modulation of NF-kappaB activation and elevated glutathione reductase may indicate glutathione depletion. Administration of N-acetylcysteine (NAC) may replenish spent glutathione and attenuate over-activation of NF-kappaB. This retrospective case series included 10 patients who were COVID-19 positive and received intravenous NAC in an attempt to attenuate the cytokine storm. Patients' outcomes were graded based on the World Health Organization symptom severity scale from 0, no evidence of infection, to 8, death. Overall, the median WHO Scale prior to NAC was 6.5, and increased by day seven, which indicated clinical worsening. This retrospective case series showed no benefit of NAC; however, further studies are needed to elucidate if differences in drug regimens would lead to positive results. [ABSTRACT FROM AUTHOR]

- Abstract
Recently, paediatric cardiac computed tomography (CCT) has caused concerns that diagnostic image quality and dose reduction may require further improvement. Consequently, this study aimed to establish institutional (local) diagnostic reference levels (LDRLs) for CCT for paediatric patients, and assess the impact of tube voltage on proposed DRLs in terms of the volume computed tomography index (CTDIvol) and dose length product (DLP). In addition, effective doses (EDs) of exposure were estimated. A population of 453 infants, whose mass and age were less than 12 kg and 2 years, respectively, were considered from January 2018 to August 2021. Based on previous studies, this number of patients was considered to be sufficient for establishing LDRLs. A group of 245 patients underwent CCT examinations at 70 kVp tube voltage with an average scan range of 23.4 cm. Another set of 208 patients underwent CCT examinations at 100 kVp tube voltage with an average scan range of 15.8 cm. The observed CTDI
vol and DLP values were 2.8 mGy and 54.8 mGy.cm, respectively. The mean effective dose (ED) was 1.2 mSv. It is concluded that provisional establishment and use of DRLs for cardiac computed tomography in children are crucial, and further research is needed to develop regional and international DRLs.

Non-alcoholic steatohepatitis (NASH) is a more dangerous form of chronic non-alcoholic fatty liver disease (NAFLD). In the current investigation, the influence of citicoline on high-fat diet (HFD)-induced NASH was examined, both alone and in combination with Lactobacillus (probiotic). NASH was induced by feeding HFD (10% sugar, 10% lard stearin, 2% cholesterol, and 0.5% cholic acid) to rats for 13 weeks and received single i.p. injection of streptozotocin (STZ, 30 mg/kg) after 4 weeks. Citicoline was given at two dose levels (250 mg and 500 mg, i.p.) at the beginning of the sixth week, and in combination with an oral suspension of Lactobacillus every day for eight weeks until the study's conclusion. HFD/STZ induced steatohepatitis as shown by histopathological changes, elevated serum liver enzymes, serum hyperlipidemia and hepatic fat accumulation. Moreover, HFD convinced oxidative stress by increased lipid peroxidation marker (MDA) and decreased antioxidant enzymes (GSH and TAC). Upregulation of TLR4/NF-kB and the downstream inflammatory cascade (TNF-α, and IL-6) as well as Pentaraxin, fetuin-B and apoptotic markers (caspase-3 and Bax) were observed. NASH rats also had massive increase in Bacteroides spp., Fusobacterium spp., E. coli, Clostridium spp., Providencia spp., Prevotella interrmedia, and P. gingivalis while remarkable drop in Bifidobacteria spp. and Lactobacillus spp. Co-treatment with citicoline alone and with Lactobacillus improve histopathological NASH outcomes and reversed all of these molecular pathological alterations linked to NASH via upregulating the expression of Nrf2/HO-1 and downregulating TLR4/NF-kB signaling pathways. These results suggest that citicoline and lactobacillus may represent new hepatoprotective strategies against NASH progression. [ABSTRACT FROM AUTHOR]

49. WAS THE NOTION OF PURGATORY KNOWN IN ANCIENT EGYPTIAN RELIGIOUS FUNERARY BELIEFS?

Attalla, Reda
- Abstract
In search for understanding the ancient Egyptian beliefs about the afterlife, most modern Egyptologists tend to focus on either the search for heaven and its variety of bliss or the search for hell and its many types of torments, but they have not searched for purgatory. Hence, this paper deals with a hypothesis that sinners and evildoers were purified in the underworld by being punished in areas of torment for some time until they got rid of their sins and mistakes; afterwards, they went to eternal the bliss that was known in ancient Egypt, and which is echoed in the ideas that we find in the Old Testament, Catholic denominations, and Islamic beliefs. Did the ancient Egyptians really believe in purification of the souls of sinners before they departed from the areas of torment to the eternal life of bliss? Did textual sources specify a certain place for the purgatory? Were its concept, conditions for entry, types, and duration clearly defined in the sources? [ABSTRACT FROM AUTHOR]

Background and Objectives: Venous ulcers are recognized to be more painful and resistant to therapy than ulcers of other etiologies. Various methods have been used for the conservative treatment of venous ulcers, such as pulsed electromagnetic field (PEMF) and plantar exercise, which promote wound healing due to a range of physiological effects. The study aimed to examine the effect of combined pulsed electromagnetic field therapy and plantar flexion resistance exercise (PRE) on patients with venous leg ulcers (VLUs). Materials and Methods: The study was a prospective, randomized controlled trial. A total of 60 patients between the ages of 40 and 55 with venous ulcers were randomly assigned to 1 of 3 groups. For up to 12 weeks, the first group received PEMF therapy and plantar flexion resistance exercise (PRE) therapy in addition to conservative ulcer treatment for up to 12 weeks. The second group received only PEMF therapy in addition to conservative ulcer treatment, while the third group served as the control and received only conservative ulcer treatment. Results: At the four-week follow-up, the two experimental groups revealed a considerable variation in ulcer surface area (USA) and ulcer volume (UV), with no significant change in the control group. At the 12-week follow-up, there were significant differences between the three groups, while group A underwent the most significant changes, with mean differences at [95% confidence interval] of (−4.75, −3.82, −0.98) for USA and (−12.63, −9.55, −2.45) for UV, respectively. Conclusions: On a short-term basis, adding a plantar resistance exercise to the PEMF had no appreciable short-term effects on ulcer healing; however, their combination had more pronounced medium-term effects.
