Pork quality is determined by several attributes, among which odor and taste are the utmost significant. Therefore, this study was aimed to assess the effects of boar odor hormone concentration on the quality traits and sensory acceptability of pork. A total twenty-six (26) non-castrated 3-way crossbred (Landrace × Yorkshire × Duroc) pigs were selected with an average body weight (ABW) 115.6 kg before to slaughter. The three treatment groups (low, medium and high) were divided according to the androstenone concentration. In experiment 1, for meat quality traits carcass was selected based on androstenone concentration: low (LC, 0.64–0.69 μg/g, n = 9), medium (MC, 0.70–0.99 μg/g, n = 7) and high (HC, 1.00–1.69 μg/g, n = 10). In experiment 2, for sensory evaluation carcasses were also selected based on the abovementioned conditions. Results revealed that androstenone concentration not effect on proximate components, meat quality traits and fatty acids except palmitoleic acid. Sensory evaluation data showed that boar taint and meat boar taint were significantly increased in a concentration-dependent manner from low to high, whereas, gravy and meat flavor preference were significantly increased in LC group than HC group. In addition, correlation analysis showed that boar taint and meat boar taint were positively, and gravy and meat flavor preference were negatively correlated with boar taint hormones. In essence, our findings indicate that androstenone concentration had no effect on meat qualities, but a high concentration of androstenone had a negative effect on the sensory characteristics in uncastrated pigs.

Quail housing and diet significantly impact egg yield and quality. This study assessed the impact of diets and housing arrangements on Japanese quail's egg production, egg index, and quality. In two trials, birds were reared in cages and on the floor with a commercial layer diet (CLD), and an experimental diet (ED) for 32 weeks. Compared to floor-reared birds, cage birds achieved 50% egg production and sexual maturity first. With dietary effects, the CLD diet showed similar results. Furthermore, their feed efficiency, hen house egg production (HHEP), and hen day egg production (HDEP) were significantly higher in cage birds that consumed CLD. Bird livability was unaffected by the housing system, while birds fed CLD had longer lifespans. The housing system had no discernible effects on egg dry matter (DM), crude protein (CP), crude fat (CF), or ash percentage. Nevertheless, the egg albumen's DM, CP, ash%, yolk's DM, CP, and CF were greater in the birds fed CLD. Barring shell thickness, weight, and Haugh unit, birds raised in cages exhibited higher egg exterior index values. Besides the yolk ratio, yolk index, and albumen weight ratio, birds given CLD exhibited enhanced egg interior quality. Ultimately, the most optimal egg production performance, improved egg quality, and prolonged lifespan of Japanese quail were obtained with cage raising and feeding practices utilizing CLD.

We aimed to determine the effects of oleic acid (OA) and palmitic acid (PA), alone or in combination, on proliferation, differentiation, triacylglycerol (TAG) content, and gene expression in porcine muscle satellite cells (PMSCs). Results revealed that OA-alone- and PA + OA-treated PMSCs showed significantly increased viability than those in the control or PA-alone-treated groups. No significant effects on apoptosis were observed in all three treatments, whereas necrosis was significantly lower in OA-alone- and PA + OA-treated groups than in the control and PA-alone-treated groups. Myotube formation significantly increased in OA-alone and PA + OA-treated PMSCs than in the control and PA-alone-treated PMSCs. mRNA expression of the myogenesis-related genes MyoD1 and MyoG and of the adipogenesis-related genes PPARα, C/EBPα, PLIN1, FABP4, and FAS was significantly upregulated in OA-alone- and PA + OA-treated cells compared to control and PA-alone-treated cells, consistent with immunoblotting results for MyoD1 and MyoG. Supplementation of unsaturated fatty acid (OA) with/without saturated fatty acid (PA) significantly stimulated TAG accumulation in treated cells compared to the control and PA-alone-treated PMSCs. These results indicate that OA (alone and with PA) promotes proliferation by inhibiting necrosis and promoting myotube formation and TAG accumulation, likely upregulating myogenesis- and adipogenesis-related gene expression by modulating the effects of PA in PMSCs.

Co-culture is mimicked in vivo condition, which is influenced by adjacent cells. This study aimed to determine different myogenic genes in mono- and co-culture of satellite cells and fibroblasts. Fibroblasts and satellite cells were isolated from the piglet’s thigh muscles. The expression of PAX-7, MyoD, MyoG, and PAX-3 was downregulated in 24 h co-culture satellite cells than in monoculture. The expression of Myf-5 and CAV-1 was upregulated in 24 h co-culture satellite cells than in 24 h monoculture. The expression of PAX-7, MyoD, and Myf-5 was downregulated in 24 and 48 h co-culture fibroblasts than 24 h monoculture. The expression of MyoG and PAX-3 was upregulated in 24 and 48 h co-culture than 48 h monoculture fibroblasts. The Cyto-C was downregulated in 24 and 48 h co-culture fibroblast than 24 h monoculture. The expression of MyoG and CAV-1 was upregulated in 48 h incubation period co-culture fibroblasts than 24 h monoculture. The MyoD and CAV-1 expression were upregulated in 24 h co-culture than 24 h satellite cells and fibroblasts. The Bcl-2 and BAX were downregulated in 48 h co-culture than 24 h. This result recommended that the satellite cells and fibroblasts interaction enhance the myogenesis marker expression without cellular morphology change.

Heat stress inhibits cell proliferation as well as animal production. Here, we aimed to demonstrate that 9-mer disulfide dimer peptide (CopA3) supplementation stabilizes porcine muscle satellite cell (PMSC) proliferation and heat shock protein (HSP) expression at different temperatures. Therefore, we investigated the beneficial effects of CopA3 on PMSCs at three different temperatures (37, 39, and 41 °C). Based on temperature and CopA3 treatment, PMSCs were divided into six different groups including treatment and control groups for each temperature. Cell viability was highest with 10 µg/mL CopA3 and decreased as the concentration increased in a dose-dependent manner. CopA3 significantly increased the cell viability at all temperatures at 24 and 48 h. It significantly decreased apoptosis compared to that in the untreated groups. In addition, it decreased the apoptosis-related protein, Bcl-2-associated X (BAX), expression at 41 °C. Notably, temperature and CopA3 had no effects on the apoptosis-related protein, caspase 3. Expression levels of HSP40, HSP70, and HSP90 were significantly upregulated, whereas those of HSP47 and HSP60 were not affected by temperature changes. Except HSP90, CopA3 did not cause temperature-dependent changes in protein expression. Therefore, CopA3 promotes cell proliferation, inhibits apoptosis, and maintains stable HSP expression, thereby enhancing the heat-stress-tolerance capacity of PMSCs.

SECOND harmonic generation ,ANISOTROPY ,RAMAN spectroscopy - Abstract
Exploring 2D van der Waals (vdW) materials is of great importance to the various optoelectronics‐based applications. Herein, mono‐ and few‐layer nanoflakes of a novel 2D vdW MgTeMoO6 are prepared by facile mechanical exfoliation method. These nanoflakes remain highly stable when being exposed in air even for 1 month, which is unique compared to most of 2D materials. Temperature‐dependent Raman spectroscopy reveals that 2D MgTeMoO6 nanosheets exhibit stronger interlayer interaction than that of graphene. In situ, angle‐resolved polarized Raman spectroscopy investigation show evidences for the anisotropic photo–phonon interactions. Notably, strong in‐plane anisotropy for the second harmonic generation (SHG) independent of layer number is observed for 2D MgTeMoO6, making 2D MgTeMoO6 promising in polarization‐sensitive optoelectronic applications.

BackgroundRepetitive transcranial magnetic stimulation (rTMS) is a novel treatment for smoking cessation and delay discounting rate is novel therapeutic target. Research to determine optimal therapeutic targets and dosing parameters for long-term smoking cessation is needed. Due to potential biases and confounds introduced by the COVID-19 pandemic, we report preliminary results from an ongoing study among participants who reached study end prior to the pandemic.MethodsIn a 3 × 2 randomized factorial design, participants (n = 23) received 900 pulses of 20 Hz rTMS to the left dorsolateral prefrontal cortex (PFC) in one of three Durations (8, 12, or 16 days of stimulation) and two Intensities (1 or 2 sessions per day). We examined direction and magnitude of the effect sizes on latency to relapse, 6-month point-prevalence abstinence rates, research burden, and delay discounting rates.ResultsA large effect size was found for Duration and a medium for Intensity for latency to relapse. Increasing Duration increased the odds of abstinence 7–8-fold while increasing Intensity doubled the odds of abstinence. A large effect size was found for Duration, a small for Intensity for delay discounting rate. Increasing Duration and Intensity had a small effect on participant burden.ConclusionFindings provide preliminary support for delay discounting as a therapeutic target and for increasing Duration and Intensity to achieve larger effect sizes for long-term smoking cessation and will provide a pre-pandemic comparison for data collected during the pandemic.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT03865472].

The impact of Gestalt theoryon the photographic art image CompositionExpressive painting movement is a German and French for more points affecting the genesis and evolution of art, artists have called to resist the control of art in academic templates and obtain their freedom to express their feelings and self encloses herewith information and access to these feelings rather than show The external appearance of the subjects, or emotions. The research aims to determine the impact of the theory of Gestalt on the path of the photographic art movement, and its role in the evolution of the concepts of photography in the light of modern art schools and trends in the world. And prove that its principles are still valid in contemporary photographic art.The research problem is What are the changes brought about by Gestalt theories, ideas in the design of contemporary photo? And how it influenced the artistic vision of photography? Gestalt principles are in Visual perception are as follows:1. the ground Figure 2.Similarity 3-Proximity 4. Common region5. Continuity 6. Closure7. Focal Point-After completion of the research, the results can be formulated in the following points:- Gestalt principles adherents ideas tended to devise new forms of photographic compositions. - the principles Gestalt credit for laying the foundations for real photographic composition to become more nuanced compositions both for each component or as a whole.- Gestalt visions were formed a new photographic image are a no longer mere transfer of reality but a tool of creativity to the photographic artist, which has continued to this day and have become higher and improved production capability with the development of digital technologies and software image processors to produce photographically creative.The search ended for the following recommendations- Further studies and research for scholars and researchers in the field of professional photography ideas for principles of Gestalt.- the teaching principles of Gestalt within their curriculum in design at Department at the Faculty of applied arts Helwan University.- The photographers are working in the field of interest to study Gestalt principles to develop their creative and professional specializations.

This study was to investigate physicochemical characteristics, fatty acids, minerals and hematological alterations in broiler chickens artificially infected with 1 × 104 sporulated oocysts of Eimeria tenella. Results revealed that pH values were decreased (p ˂ .05) in the infected group (IG) at 7 and 9 days post infection (dpi) than those at 5 dpi, although no significant differences between the non-infected group (NIG) and IG. Infection with E. tenella did not affect meat colour parameters except that redness was lower (p ˂ .05) than that in the NIG. Cooking loss was decreased (p ˂ .05) in NIG and IG at 7 and 9 dpi than that at 5 dpi. Thiobarbituric acid reactive substance (TBARS) value was increased (p ˂ .05) in IG at 7 dpi than 5 or 9 dpi and NIG (p ˂ .01). Total protein (TP) and total cholesterol (TC) were significantly lowered in IG at 5 dpi. Other blood parameter results showed decreases of glucose (GLU), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) in infected chicken at 7 dpi compared to those in the NIG without significance. However, albumin (ALB) level was decreased (p ˂ .01) in the IG compared with NIG at 5 dpi. Levels of aspartate aminotransferase (AST) were lowered (p < .05) in the IG than NIG at 7 dpi. Mineral contents of Ca, Mg, Cu, and Zn were lowered (p ˂ .01) in the IG than those in the NIG at 7 dpi. Based on these results indicate that a low dose of E. tenella has no impact on meat quality traits, fatty acids although it can slightly affect blood parameters and mineral contents.HIGHLIGHTS The low dose of Eimeria tenella has no impact on meat quality traits and fatty acids of broiler meat. A significant increase in some blood parameter is observed in infected broiler chickens at 9 dpi. Mineral contents of Ca, Mg, Cu and Zn decreases in infected broiler meat at 7 dpi.

Abstract Background Despite the considerable success of comprehensive tobacco control efforts, tobacco use remains one of the greatest preventable causes of death and disease today. Over half of all smokers in the US make quit attempts every year, but over 90% relapse within 12 months, choosing the immediate reinforcement of smoking over the long-term benefits of quitting. Conceptual and empirical evidence supports continued investigation of high frequency repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex in reducing relapse and decreasing cigarette consumption. While this evidence is compelling, an optimal dosing strategy must be determined before a long-term efficacy trial can be conducted. The goal of this study is to determine a dosing strategy for 20 Hz rTMS that will produce the best long-term abstinence outcomes with the fewest undesirable effects. Methods This is a fully crossed, double-blinded, sham-controlled, 3x2x2 randomized factorial study. The three factors are duration (stimulation days: 8, 12, and 16); intensity (900 or 1800 pulses per day); and sham control. Participants (n = 258) will consist of adults (18–65) who are motivated to quit smoking cigarettes and who will be followed for 6 months post-quit. Outcomes include latency to relapse, point prevalence abstinence rates, delay discounting rates, cognitive-behavioral skills acquisition, and multiple measures of potential undesirable effects that impact participant compliance. Discussion This study integrates existing theoretical concepts and methodologies from neuropsychology, behavioral economics, brain stimulation, clinical psychology, and the evidence-based treatment of tobacco dependence in the development of a promising and innovative approach to treat tobacco dependence. This study will establish an optimal dosing regimen for efficacy testing. Findings are expected to have a significant influence on advancing this approach as well as informing future research on clinical approaches that combine rTMS with other evidence-based treatments for tobacco dependence and perhaps other addictions. Trial registration Clinical Trials NCT03865472 (retrospectively registered). The first participant was fully enrolled on November 26, 2018. Registration was posted on March 7, 2019.

ABSTRACT: This study determined the relationship between inflammation and gluconeogenesis level in broilers in different durations of heat stress. A total of 240 Ross 308 broilers were offered control and heat stress temperature from 21 to 35 d post-hatch, each experimental group had 8 replications, and each replication obtained 15 broilers. The temperature in the control (Ctrl) group and heat stress group were maintained at 24 ± 1°C and 34 ± 1°C, respectively throughout the experimental period. Based on the duration of heat stress, the heat stress group was divided into 2 subgroups, like, 7-d heat stress (28-day-old broiler) designated ST group and 14-d heat stress (35-day-old broiler) designated the LT group. The ad libitum commercial feed and fresh water were provided to all experimental broilers during the experiment. The growth performance of experimental broilers was calculated at 35 d. However, the liver and blood samples were collected from the Ctrl group in 21 d, as well as these samples were collected from the heat stress ST and LT groups in 28-d and 35-d, respectively. Obvious gene expression of immunity, gluconeogenesis, glycogenolysis, and glycogenesis, as well as glucose-6-phosphate dehydrogenase and adenosine triphosphate was determined in the liver sample. The blood glucose concentration and histopathology of the liver was also examined in the different grouped broilers. Body weight, weight gain, and feed intake significantly decreased in the 35-d heat stress group than the Ctrl group. However, the feed conversion ratio increased at the 35-d heat stress group than the Ctrl group. The amount of glucose-6-phosphate dehydrogenase was significantly higher in ST and LT groups than Ctrl, whereas the blood glucose level was downregulated in the LT group. The amount of adenosine triphosphate was significantly decreased in the LT group than the Ctrl and ST groups. Heat stress acts as an impediment to the general relation between gluconeogenesis and immunity, as well as changes cellular structure. This experiment contributed to the establishment of a relationship between gluconeogenesis and immunity, which affects the growth performance of broilers during heat stress.

General Medicine - Abstract
OBJECTIVE Limited evidence exists on the utility of repeat neuroimaging in children with mild traumatic brain injuries (mTBIs) and intracranial injuries (ICIs). Here, the authors identified factors associated with repeat neuroimaging and predictors of hemorrhage progression and/or neurosurgical intervention. METHODS The authors performed a multicenter, retrospective cohort study of children at four centers of the Pediatric TBI Research Consortium. All patients were ≤ 18 years and presented within 24 hours of injury with a Glasgow Coma Scale score of 13–15 and evidence of ICI on neuroimaging. The outcomes of interest were 1) whether patients underwent repeat neuroimaging during index admission, and 2) a composite outcome of progression of previously identified hemorrhage ≥ 25% and/or repeat imaging as an indication for subsequent neurosurgical intervention. The authors performed multivariable logistic regression and report odds ratios and 95% confidence intervals. RESULTS A total of 1324 patients met inclusion criteria; 41.3% of patients underwent repeat imaging. Repeat imaging was associated with clinical change in 4.8% of patients; the remainder of the imaging tests were for routine surveillance (90.9%) or of unclear prompting (4.4%). In 2.6% of patients, repeat imaging findings were reported as an indication for neurosurgical intervention. While many factors were associated with repeat neuroimaging, only epidural hematoma (OR 3.99, 95% CI 2.22–7.15), posttraumatic seizures (OR 2.95, 95% CI 1.22–7.41), and age ≥ 2 years (OR 2.25, 95% CI 1.16–4.36) were significant predictors of hemorrhage progression and/or neurosurgery. Of patients without any of these risk factors, none underwent neurosurgical intervention. CONCLUSIONS Repeat neuroimaging was commonly used but uncommonly associated with clinical deterioration. Although several factors were associated with repeat neuroimaging, only posttraumatic seizures, age ≥ 2 years, and epidural hematoma were significant predictors of hemorrhage progression and/or neurosurgery. These results provide the foundation for evidence-based repeat neuroimaging practices in children with mTBI and ICI.

Introduction: Therapy and immune mediated processes are associated with clonal evolution in multiple myeloma (MM). In this study, we performed whole-exome sequencing (WES) and single cell RNA sequencing (scRNA-seq) on plasma cells (PC) from bone marrow aspirates of the iliac crest (BM) and corresponding osteolytic lesions (OL) to investigate spatial heterogeneity in patients with newly diagnosed (NDMM) and relapsed/refractory MM (RRMM). Next generation flow (NGF) and T-cell receptor sequencing (TCRseq) were performed to investigate the immunogenomic landscape surrounding malignant PC. Methods: In a prospective trial, 18 patients (NDMM: n=10; RRMM: n=8) consented to an imaging-guided biopsy of an OL in addition to the regular BM sampling. At inclusion, 37 different locations were biopsied. Follow-up samples were obtained from 5 patients in remission after therapy. After CD138+ selection, PC were subjected to WES and scRNA-seq (Chromium, 10x genomics). TCRseq was performed using multiplex PCR (ImmunoSEQ, Adaptive biotechnologies) on the CD138- fraction. For scRNA-seq data analyses, Cell Ranger (v3.1.0) and the Seurat R toolkit (v3.1) were used. TCRseq data were analyzed with immunoSEQ ANALYZER (v3.0) and the immunarch R toolkit (v0.6.6.). NGF was performed to study subsets of T-, B-, NK- and dendritic cells (DC). Results: Median PC infiltration was higher in OL compared to random BM (50.0% vs 12.5%, p=0.041). WES revealed more mutations in RRMM compared to NDMM (median; range: 189;120-523 vs 71;23-136, p Conclusion: We report the first prospective clinical trial to investigate spatiotemporal immunogenomic heterogeneity in multiple myeloma as assessed by WES and scRNA-seq of PC and NGF and TCRseq of the non-PC compartment. We demonstrate spatial evolution and reduced TCR diversity especially in patients with RRMM and/or EMD. ScRNA-seq adds another layer of complexity compared to WES and helps identifying how PC create an immune suppressive BM niche. Disclosures Merz: Amgen, BMS, Celgene, Takeda: Honoraria.

Photograph design is an original part of it, and the creativity of the photographer depends on its ability to use the elements of the image to produce creative design, using these elements innovatively. The contemporary technological development has helped to create the image faster, and less time, not only when photography exists, Grid), but gave some cameras the possibility of cutting and modifying and even work on the image on the inside of the camera, and with the potential of broadcasting from the camera on the computer or mobile via Wi-Fi has become both photography and the transfer of the image quickly and directly from the location of photography to anywhere in the world does not constitute No difficulty like the previous.Technology is the key to photography, and its integration with the eye of creative photography produces original and innovative images, and with the development of digital processing programs for photographs such as Photoshop has been integrated some of the characteristics that enabled the rapid access to a distinctive photographic balance, but a number of factors helping to produce more innovative images accurately And faster.The size of the sensors varies depending on the manufacturer of the devices producing the digital image, whether it is a camera or a mobile phone.The problem of research is the definition of innovative strategy to produce and improve the level of innovation in the balance of the image through the integration of both technology and photography using the program Photoshop to provide a picture visually integrated and the extent of the possibility of applying the rules of configuration on all sizes of sensors and the main question is whether the application of theories and practices of composition with different The size of the sensations of a rectangle of a square as well as the difference of proportions of rectangles from one factory to another.In the research results, we find that technology is an integral part of creating a photographic image in our digital work. It encourages innovation by studying design, especially balancing, using the golden ratio, the primary element in any base of the composition, which helps to solve the problem of creativity and access to a distinct original production. And we are convinced that creativity is not affected by the different sizes of sensors, which ultimately leads to the difference of the final image.

This study was performed to elucidate the effects of linoleic acid (LA), oleic acid (OA) and their combination (LA + OA) on cell proliferation, apoptosis, necrosis, and the lipid metabolism related gene expression in bovine satellite cells (BSCs), isolated from bovine muscles. Cell viability was significantly increased with the OA and LA treatment. Furthermore, LA + OA enhanced cell proliferation in a dose-dependent manner (10 to 100 µM), whereas it lowered at 250 µM. In addition, a cell-cycle analysis showed that 100 µM of LA and OA markedly decreased the G0/G1 phase proportion (62.58% and 61.33%, respectively), compared to controls (68.02%), whereas the S-phase cells’ proportion was increased. The ratio of G2/M phase cells was not significantly different among the groups. Moreover, analyses with AO/EtBr staining showed that no apoptosis occurred. Necrosis were determined by flow cytometry using Annexin V-FITC/PI staining which revealed no early apoptosis in the cells pretreated with LA or OA, but occurred in the LA + OA group. We also analyzed the mRNA expression of lipid metabolizing genes such as peroxisome proliferator receptor alfa (PPARα), peroxisome proliferator receptor gamma (PPARγ), acyl-CoA oxidase (ACOX), lipoprotein lipase (LPL), carnitine palmitoyl transferase (CPT-1), and fatty-acid binding protein4 (FABP4), which were upregulated in LA or OA treated cells compared to the control group. In essence, LA and OA alone promote the cell proliferation without any apoptosis and necrosis, which might upregulate the lipid metabolism related gene expressions, and increase fatty-acid oxidation in the BSCs’ lipid metabolism.

- Abstract
Fluoride is one of the anions that endanger human health at concentrations lower and higher than the standard, also is one of the main problems in most parts of the world, where about 200 million people from 25 countries are exposed to high or low concentrations of fluoride from groundwater sources. . This descriptive and analytical study was conducted in shendi City to determine concentrations level of fluoride in ground water. 150 samples of ground water were tested per season (50 samples for each season), The water samples were collected from ground water sources (wells), distribution system and storage facilities that are used directly for drinking purpose in the community per seasons. Analyzing of samples had been completed according to standard methods for examinations of water, in this study used photometer device for determination concentrations of fluoride. Our study revealed that: the quality of ground water in study area is low fluoride content and below the optimum levels that recommended by WHO and SSMO guidelines for drinking water and seasonal variations have effects on fluoride’s solubility and concentrations. Based on the findings of this study we recommend that: community must not depend totally on ground water as main source for fluoride, and community in study area should be use other sources for fluoride intake to obtain on daily required amount of fluoride for protection the health.

Osteolytic lesions (OL) characterize symptomatic multiple myeloma. The mechanisms of how malignant plasma cells (PC) cause OL in one region while others show no signs of bone destruction despite subtotal infiltration remain unknown. We report on a single-cell RNA sequencing (scRNA-seq) study of PC obtained prospectively from random bone marrow aspirates (BM) and paired imaging-guided biopsies of OL. We analyze 148,630 PC from 24 different locations in 10 patients and observe vast inter- and intra-patient heterogeneity based on scRNA-seq analyses. Beyond the limited evidence for spatial heterogeneity from whole-exome sequencing, we find an additional layer of complexity by integrated analysis of anchored scRNA-seq datasets from the BM and OL. PC from OL are characterized by differentially expressed genes compared to PC from BM, including upregulation of genes associated with myeloma bone disease like DKK1, HGF and TIMP-1 as well as recurrent downregulation of JUN/FOS, DUSP1 and HBB. Assessment of PC from longitudinally collected samples reveals transcriptional changes after induction therapy. Our study contributes to the understanding of destructive myeloma bone disease.

This study was conducted to determine the effects of garlic on egg per gram (EPG) count of feces for gastrointestinal parasites, live weight, and hematological parameters in Black Bengal goat. A total of 18 dry does of 18-22 months of age were divided into 3 groups as T0, T1 and T2; where, each group comprised of 6 goats. The goats of T0 were feed with normal feeds, whereas the goats of T1 and T2 were fed with normal feeds plus 25 mL and 50 mL of 10% water solution of garlic twice per day, respectively for 60 days. The EPG count was performed by McMaster counting chamber, and live weight was measured by digital electric balance. EPG count for gastrointestinal parasites was found significantly lower in the treatment groups as compared to T0. Weight gain was recorded significantly higher in the treatment groups. The hematological parameters like total leucocyte count (TLC), erythrocyte sedimentation rate (ESR), packed cell volume (PCV), hemoglobin (Hb) and total erythrocyte count (TEC) showed significant changes in the treatment groups. The study suggests that 10% water solution of garlic is a useful supplementation to decrease EPG count, body weight gain; thus, the 10% aqueous garlic solution can improve the general health condition of goat.

OBJECTIVE Tethered cord syndrome (TCS) is a clinical and radiographic diagnosis of pathological stretching of the spinal cord leading to progressive loss of neurological function. The gold standard treatment for TCS is a tethered cord release. However, detethering involves significant risks of spinal cord injury and high rates of retethering. To mitigate these risks, the concept of spinal column shortening (SCS) to decrease spinal cord tension has become an alternative to detethering. In this study, the authors applied SCS to a pediatric and emerging adult population affected by secondary TCS. METHODS A retrospective review of a prospective database at the authors’ tertiary pediatric institution was performed. The Pediatric Quality of Life Inventory, patient- and parent-reported outcomes, and urodynamics were used to evaluate the outcomes of TCS treated with SCS. RESULTS A total of 41 patients with secondary TCS were treated with SCS. The average age at the time of surgery was 15.9 years (range 5–55 years). Preoperative symptoms evaluated included pain (33 patients), weakness (30 patients), and bladder/bowel dysfunction (39 patients). The most common level of spinal column osteotomy was T12, with spinal fusion between T10 and L2. The mean follow-up time was 22.6 months (range 8–45 months). For patients with at least 12 months of follow-up, subjective clinical improvements were reported in 21/23 (91.3%) of those with preoperative pain (p < 0.01); in 16/24 (66.7%) of patients with weakness (p < 0.01), and in 15/29 (51.7%) of those with bladder/bowel dysfunction (p < 0.01). The median differences in initial and most recent Pediatric Quality of Life Inventory results were +5 for patient-reported scores (n = 19, p = 0.04) and +5 for parent-reported scores (n = 19, p = 0.08). Formal urodynamics performed at a median of 3.5 months after surgery documented stable to improved bladder function in 16/17 patients, with a median improvement in one classification category (n = 17, p = 0.01). CONCLUSIONS SCS continues to represent a safe and efficacious alternative to traditional spinal cord untethering for TCS in children and emerging adults, as documented by objective formal urodynamics and patient- and parent-reported outcomes.

OBJECTIVE CSF shunts are the most common procedures performed in the pediatric neurosurgical population. Despite attempts in multiple studies, a superior shunt valve has never been shown. Because of this, the authors aim was to examine the impact of shunt valve standardization at their institution to determine if there is a difference in surgical cost, operative time, or short-term postoperative shunt failure. METHODS A retrospective analysis at the authors’ institution was performed for all new CSF diversion shunts, as well as shunt revisions requiring a new valve, or a new valve and at least a new proximal or distal catheter over a 1-year period (January 1, 2016, to December 31, 2016). After a period of transition, neurosurgeons were encouraged to use only one type of fixed-differential-pressure valve and one type of programmable valve when performing shunt surgeries. These patients who underwent “standardized” shunt surgery over a 1-year period (January 1, 2018, to December 31, 2018) were then compared to patients in the prestandardization epoch. All patients were followed for a 12-month period after surgery. Demographic information, surgical cost, operative time, and postoperative shunt failure data were collected in all patients in the study. RESULTS The authors analyzed 87 shunt surgeries in patients prior to standardization and 94 shunt surgeries in patients after standardization. The rate of violation of the standardized shunt valve policy after implementation was 5.3% (5 of 94 procedures). When comparing the prestandardization group to those who received the standardized valve, operative costs were less ($1821.04 vs $1333.75, p = 0.0034). There was no difference in operative times between groups (78 minutes vs 81 minutes, p = 0.5501). There was no difference in total number of shunt failures between the two groups at 12 months after surgery (p = 0.0859). The rate of postoperative infection was consistent with the literature at 8%. CONCLUSIONS In accordance with quality improvement principles, the reduction of unexplained clinical variance invariably leads to a decrease in cost and, more importantly, increased value. In this study, the implementation of a standardized shunt valve decreased operative cost. There were no differences in postoperative shunt failures at 12 months after surgery and no differences in length of surgery. Standardizing shunt valves in the treatment of pediatric hydrocephalus seems to be cost-effective and safe.

This study was to investigate physicochemical characteristics, fatty acids, minerals and hematological alterations in broiler chickens artificially infected with 1 × 104 sporulated oocysts of Eimeria tenella. Results revealed that pH values were decreased (p ˂ .05) in the infected group (IG) at 7 and 9 days post infection (dpi) than those at 5 dpi, although no significant differences between the non-infected group (NIG) and IG. Infection with E. tenella did not affect meat colour parameters except that redness was lower (p ˂ .05) than that in the NIG. Cooking loss was decreased (p ˂ .05) in NIG and IG at 7 and 9 dpi than that at 5 dpi. Thiobarbituric acid reactive substance (TBARS) value was increased (p ˂ .05) in IG at 7 dpi than 5 or 9 dpi and NIG (p ˂ .01). Total protein (TP) and total cholesterol (TC) were significantly lowered in IG at 5 dpi. Other blood parameter results showed decreases of glucose (GLU), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) in infected chicken at 7 dpi compared to those in the NIG without significance. However, albumin (ALB) level was decreased (p ˂ .01) in the IG compared with NIG at 5 dpi. Levels of aspartate aminotransferase (AST) were lowered (p < .05) in the IG than NIG at 7 dpi. Mineral contents of Ca, Mg, Cu, and Zn were lowered (p ˂ .01) in the IG than those in the NIG at 7 dpi. Based on these results indicate that a low dose of E. tenella has no impact on meat quality traits, fatty acids although it can slightly affect blood parameters and mineral contents.HIGHLIGHTS The low dose of Eimeria tenella has no impact on meat quality traits and fatty acids of broiler meat. A significant increase in some blood parameter is observed in infected broiler chickens at 9 dpi. Mineral contents of Ca, Mg, Cu and Zn decreases in infected broiler meat at 7 dpi.

Background: Medically refractory epilepsy constitutes up to one-third of the epilepsy pediatric patients. Corpus callosotomy (CC) has been used for the treatment of medically refractory epilepsy in children with atonic seizures and generalized tonic–clonic (GTC) seizures. In this case series study, we are describing a novel technique for CC using the frameless navigation probe through a minicraniotomy. Methods: Thirteen pediatric patients with the diagnosis of medically refractory epilepsy predominantly GTC with drop attack who underwent extensive Phase I. An L-shape was done, then through a 4 × 3 cm craniotomy, we were able to open the interhemispheric fissure until the corpus callosum is visualized. The Stealth probe is then used to go down to the midline raphe which is followed anteriorly then traced posteriorly to the anterior border of the vein of Galen. Finally, the Stealth probe is used to confirm the completeness of the callosotomy. Results: The procedure was accomplished successfully with no intraoperative complications; mean surgical time is 3 h:07 m. The mean follow-up was 31.5 months. All patients achieved significant seizure control. No patients experienced worsening of their atonic seizures after surgery compared with their preoperative state; however, six patients achieved Engel Class I, four patients achieved Engel Class II, and three patients achieved Engel Class III. Conclusion: Complete CC using a frameless navigation probe is a novel and effective technique for the treatment of medically refractory epilepsy with a very good surgical and seizure outcomes, minimal neurological morbidity, minimal blood loss, and short OR time.

Background Despite the considerable success of comprehensive tobacco control efforts, tobacco use remains one of the greatest preventable causes of death and disease today. Over half of all smokers in the US make quit attempts every year, but over 90% relapse within 12 months, choosing the immediate reinforcement of smoking over the long-term benefits of quitting. Conceptual and empirical evidence supports continued investigation of high frequency repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex in reducing relapse and decreasing cigarette consumption. While this evidence is compelling, an optimal dosing strategy must be determined before a long-term efficacy trial can be conducted. The goal of this study is to determine a dosing strategy for 20 Hz rTMS that will produce the best long-term abstinence outcomes with the fewest undesirable effects. Methods This is a fully crossed, double-blinded, sham-controlled, 3x2x2 randomized factorial study. The three factors are duration (stimulation days: 8, 12, and 16); intensity (900 or 1800 pulses per day); and sham control. Participants (n = 258) will consist of adults (18–65) who are motivated to quit smoking cigarettes and who will be followed for 6 months post-quit. Outcomes include latency to relapse, point prevalence abstinence rates, delay discounting rates, cognitive-behavioral skills acquisition, and multiple measures of potential undesirable effects that impact participant compliance. Discussion This study integrates existing theoretical concepts and methodologies from neuropsychology, behavioral economics, brain stimulation, clinical psychology, and the evidence-based treatment of tobacco dependence in the development of a promising and innovative approach to treat tobacco dependence. This study will establish an optimal dosing regimen for efficacy testing. Findings are expected to have a significant influence on advancing this approach as well as informing future research on clinical approaches that combine rTMS with other evidence-based treatments for tobacco dependence and perhaps other addictions. Trial registration Clinical Trials NCT03865472 (retrospectively registered). The first participant was fully enrolled on November 26, 2018. Registration was posted on March 7, 2019.
