The main aim of this article is to explore the real-life problem-solving potential of the proposed Lévy flight-based chaotic gravitational search algorithm (LCGSA) for the minimization of engineering design variables of speed reducer design (SRD), three bar truss design (TBTD), and hydrodynamic thrust bearing design (HTBD) problems. In LCGSA, the diversification of the search space is carried out by Lévy flight distribution. Simultaneously, chaotic maps have been utilized for the intensification of the candidate solutions towards the global optimum. Moreover, the penalty function method has been used to deal with the non-linear and fractional design constraints. The investigation of experimental outcomes has been performed through various performance metrics like statistical measures, run time analysis, convergence rate, and box plot analysis. Moreover, statistical verification of experimental results is carried out using a signed Wilcoxon rank-sum test. Furthermore, eleven heuristic algorithms were employed for comparative analysis of the simulation results. The simulation outcomes clearly show that LCGSA provides better values for TBTD and HTBD benchmarks than standard GSA and most of the competing algorithms. Besides, all the participating algorithms, including LCGSA, have the same results for the SRD problem. On the qualitative side, LCGSA has successfully resolved entrapment in local minima and convergence issues of standard GSA. more...

Background and Study Aims: Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disorder, affecting 23% to 32% of the global population. This clinical study aimed to assess the efficacy of Curcuma zedoaria Rosc. compared to vitamin E in managing NAFLD., Patients and Methods: In this randomized, single-blind, standard-controlled study, 68 patients with grade 1 (mild) and grade 2 (moderate) NAFLD were randomly assigned to receive either Curcuma zedoaria Rosc. powder in capsule form (500 mg orally, twice a day) in the test group or vitamin E (400 mg orally, twice a day) in the control group for 60 days. Secondary endpoints included improvements in fatty liver grades, ultra-sonographic liver span, lipid profile, and liver function parameters after 60 days. Primary endpoints included improvements in dull ache intensity in the right hypochondrium (RHC), dyspepsia, anorexia, and severity of malaise assessed at days 0, 15, 30, 45, and 61., Results: Per protocol analysis was performed on 50 patients who completed the study. Both test and control groups showed significant improvement in dull ache severity in the RHC (p < 0.0001). The test group exhibited more favorable outcomes post-treatment (Chi-sq = 23.17, df = 2, p < 0.0001). Dyspepsia severity significantly improved in both groups post-treatment (p = 0.005 and p = 0.010, respectively), with the test group showing slightly better outcomes. Anorexia significantly improved in the test group (p = 0.016) from 72.00 % reporting absence post-treatment to 100.00 % absence, while the control group showed improvement without statistical significance (p = 0.102). Malaise severity significantly improved in the test group (p < 0.0001), with 84.00 % reporting absence post-treatment compared to 8.00 % in the control group, showing significant differences (p < 0.0001). Both groups exhibited a significant reduction in liver span post-treatment (p-value < 0.0001) without inter- group differences. Fatty liver grades improved significantly in both groups post-treatment (p < 0.0001), with no significant difference between groups (Chi-sq = 4, df = 2, p = 0.1353). There were no changes in liver function markers and lipid parameters in both groups, though the test drug demonstrated a slight reduction in serum triglyceride levels. No drug-related adverse events were observed during the trial., Conclusion: The study revealed that Curcuma zedoaria Rosc. is effective in managing NAFLD, showing better outcomes than vitamin E in subjective parameters like dyspepsia, malaise, anorexia, and dull ache in RHC. With no observed drug-related adverse events, Curcuma zedoaria Rosc. could be a suitable alternative to conventional treatment modalities for NAFLD., Competing Interests: Declaration of competing interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 Pan-Arab Association of Gastroenterology.

An exopolysaccharide (EPS)-producing bacterial strain was isolated from fermented soy milk and identified as Weissella cibaria strain Fiplydextran through morphological, biochemical and 16S rDNA sequence analysis. Here, we report the optimisation of cultural conditions for the organism to achieve maximum EPS production, along with its molecular characterisation, functional properties, and prebiotic potential. The exceptionally high EPS yield (0.61 g per g of sucrose) was obtained from the optimised medium (200 g/L of sucrose, 15 g/L of yeast extract) at 30 °C after 48 h. HPAEC-PAD analysis revealed that the EPS is homopolymer of glucose having M w as 3.23 × 10 7  Da determined using viscosity method. Methylation analysis and NMR results confirmed the EPS as dextran with α (1 → 6)-linkage (96.5 %) as main chain and α (1 → 3)- as branch chain linkage (3.5 %). Thermogravimetric analysis exhibited higher thermal stability of EPS. The EPS was observed to support the growth of Bacteroides spp. in pure culture form but not that of Lactobacillus or Bifidobacterium spp. However, a low level of bifidogenic activity was observed upon use of mixed culture of B. fragilis and B. longum. The research implies industrial applications of W. cibaria Fiplydextran for the production of high molecular weight dextran with better yield., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

The people of Jammu and Kashmir rely heavily on fish as a source of nutritional protein. Fishes also contribute significantly to the local economy of this area. However, several infectious disorders, some of which are brought on by helminth parasites, constitute a persistent threat to fish. The primary goal of the present review is to find out the parasites in common fishes found in Jammu and Kashmir as well as the impact of parasites on fishes and sickness on human health. Like other animals, fishes are susceptible to several diseases, many of which are external in origin while others are internal in origin. Fishes are known to be susceptible to parasites, fungi, bacteria, viruses, and other external agents that can cause disease, and they also commonly experience organic and degenerative problems internally. Fish parasites have significant impact on both fish and human health. These diverse organisms, including protozoa, helminths, and crustaceans, can infest various fish tissues, leading to detrimental effects. Infested fish often experience reduced growth, weakened immune system, behavioral changes, physical damage, and even mortality. Economically, fish parasites can diminish the value of fish in markets and increase production costs in fisheries and aquaculture. Moreover, fish parasites pose potential human health risks. Consumers who ingest raw or undercooked fish containing certain parasites, like Anisakis spp., may develop gastrointestinal discomfort or anisakiasis. Proper cooking and freezing can mitigate this risk. While fish parasites are primarily harmful, they also play ecological roles, contributing to biodiversity and ecosystem stability by controlling fish populations. Understanding the complex interactions between parasites, fish, and their environment is vital for effective fisheries management, aquaculture practices, and public health measures. Striking a balance between controlling parasite infestation and maintaining ecological integrity is crucial for sustaining both fish populations and human well-being., Competing Interests: Conflict of interestThe authors declare no conflict of interest., (© Indian Society for Parasitology 2024.

This study aimed at optimizing process protocols for development of low glycemic index (GI) rice flour (LGIRF) by employing enzymatic hydrolysis method using central composite rotatable design (CCRD). LGIRF was evaluated for pasting, farinographic, spectroscopic and microbiological attributes. Independent variables for optimization included concentrations of α-amylase (0.02-0.12 %), glucoamylase (0.02-0.24 %), as well as the incubation temperature (55-80°C). Resistant starch (RS), glycemic index (GI) and glycemic load (GL) were investigated as response variables. The optimum conditions for development of LGIRF with better quality were- α-amylase concentration of 0.040 %, glucoamylase concentration of 0.070 % and an incubation temperature of 60 °C. The results of mineral analysis revealed significantly (p < 0.05) lower levels of boron, potassium, zinc, phosphorus, magnesium, and manganese in LGIRF, while iron and copper were significantly higher. The viscosity profile as evident from pasting profile and farinographic characteristics of LGIRF were significantly (p < 0.05) lower than native rice flour. 1 H NMR and 13 C NMR spectroscopic studies showed an increase in flexible starch segments and a decrease in amorphous portion of starch LGIRF, along with chemical shift alterations in carbons 1 and 4. Free fatty acids and total plate count were significantly (p < 0.05) higher in LGIRF although was within limits., Competing Interests: Declaration of competing interest None of the authors report any conflict of interest., (Copyright © 2024 Elsevier Ltd.

Globally, the poultry industry is seriously threatened by coccidiosis caused by various species of Eimeria. This protozoan parasite inhabits the epithelial lining of the gastrointestinal tract of poultry globally and can cause serious clinical disease. The present study was carried out on poultry farms located in various regions of Kashmir, India, to investigate the prevalence and phylogenetic relationships of Eimeria species affecting broiler chickens. Over a period of one year, fecal samples were collected from 60 poultry farms in Kashmir and morphological and molecular techniques were employed for Eimeria species identification. Results revealed a high prevalence of coccidiosis, with 58.3% (35/60) of farms positive for Eimeria. The most prevalent species were E. tenella (31/35, 88.6%) followed by E. acervulina (25/35, 71.4%), E. maxima (19/35, 54.3%), E. mitis (18/35, 51.4%), and E. necatrix (9/35, 25.7%). Seasonal variation in prevalence was also observed, with the highest rates in autumn (86.7%) and summer (66.7%). Additionally, younger birds (3-4 weeks) exhibited higher infection rates (85.7%) compared to older birds (57.9%) (5-6 weeks). Mixed infection was found in 94.2% (33/35) of positive farms. Phylogenetic analysis using ITS1 sequences confirmed species clustering and revealed evolutionary relationships among Eimeria species. E. tenella and E. necatrix formed a distinct clade, while E. acervulina formed another. The study underscores the importance of molecular techniques in accurate species identification and provides valuable insights into the epidemiology of coccidiosis in poultry in Kashmir. Effective control strategies, including vaccination and improved management practices, are necessary to mitigate the economic losses associated with this widespread poultry disease., (© 2024.

Here, we describe a new species of Crotalaria L. discovered in Mengla County, Xishuangbanna Dai Autonomous Prefecture, Yunnan, China. The new species, Crotalariamenglaensis S.A.Rather, was confirmed by identifying diagnostic morphological characteristics, performing principal component analyses of phenotypic traits, and phylogenetic analyses based on nuclear ITS and plastid mat K sequences. Phylogenetic analyses recovered the two accessions of the new species to be sister to C.bracteata Roxb. ex DC. In turn, these two species formed the sister clade to the two accessions of C.incana L. The morphometric analyses revealed that all three species were distinct, while the analyses of distinctive characters enabled unambiguous distinction of the new species by its growth habit, leaflets, flower structure and pod morphology. In contrast to the two related species, the new species is currently known only from ca. 100 mature individuals. Thus, this species is considered to be critically endangered., Competing Interests: The authors have declared that no competing interests exist., (Shabir A.

Climate change has caused changes in environmental conditions, leading to both low temperature (LT) and high humidity (HH) stress on crops worldwide. Therefore, there is a growing need to enhance our understanding of the physiological and molecular mechanisms underlying LT and HH stress tolerance in cucumbers, given the significance of climate change. The findings of this study offer a comprehensive understanding of how the transcriptome and hormone profiles of cucumbers respond to LT and HH stress. In this study, cucumber seedlings were subjected to LT and HH stress (9/5 °C day/night temperature, 95% humidity) as well as control (CK) conditions (25/18 °C day/night temperature, 80% humidity) for 24, 48, and 72 h. It was observed that the LT and HH stress caused severe damage to the morphometric traits of the plants compared to the control treatment. The concentrations of phytohormones IAA, ethylene, and GA were lower, while ABA and JA were higher during LT and HH stress at most time points. To gain insights into the molecular mechanisms underlying this stress response, RNA-sequencing was performed. The analysis revealed a total of 10,459 differentially expressed genes (DEGs) with annotated pathways. These pathways included plant hormone signal transduction, protein processing in the endoplasmic reticulum, MAPK signaling pathway, carbon fixation in photosynthetic organisms, and glycerolipid metabolism. Furthermore, 123 DEGs associated with hormone signaling pathways were identified, and their responses to LT and HH stress were thoroughly discussed. Overall, this study sheds light on the LT and HH tolerance mechanisms in cucumbers, particularly focusing on the genes involved in the LT and HH response and the signaling pathways of endogenous phytohormones., Competing Interests: Declaration of Competing Interest I would like to declare on behalf of my co-authors that the work described is original research that has not been published previously, and not under consideration for publication elsewhere, in whole or in part. I confirmed that no conflict of interest exists in the submission of this manuscript, and is approved by all authors for publication in your journal., (Copyright © 2023 Elsevier B.V.

Introduction. Dextransucrase produced by Streptococcus mutans plays a vital role in the formation of dental caries by synthesizing exopolysaccharides from sucrose, which helps in the attachment of microbes to the tooth surface, causing caries. Exploring antibody production against S. mutans antigens could be an effective method to protect against dental caries. Hypothesis. Dextransucrase antibodies may help in the prevention of caries formation by inhibiting essential cariogenic factors. Aims. The aim of this study was to investigate the effects of dextransucrase antibodies on biofilm formation and certain associated cariogenic factors of S. mutans . Methodology. Dextransucrase was purified from culture of S. mutans . The antisera against the enzyme were raised in rabbits. The effect of dextransucrase antibodies on biofilm formation was studied using scanning electron microscopy, fluorescence microscopy and quantitative real-time polymerase chain reaction. The effects of the antibodies on associated cariogenic factors were examined using established methods. The cross-reactivity of antibodies with human lung, liver, heart, thyroid and kidney tissues was evaluated by immunohistochemistry. Results. Our findings showed impaired biofilm formation in S. mutans in the presence of dextransucrase antibodies. Genes associated with biofilm formation such as gtfB, gtfC, brpA, relA, Smu.630 and vicK were downregulated (50-97 %) by dextransucrase antibodies in S. mutans . The adherence of S. mutans to glass surface was reduced by 58 % and hydrophobicity was reduced by 55.2 % in the presence of the antibodies compared to the controls. Immunohistochemistry studies revealed no cross-reactivity of human tissues with dextransucrase antibodies. Conclusions. These findings suggest that antibodies raised against dextransucrase exhibit a profound inhibitory effect on biofilm formation and vital cariogenic factors of S. mutans , which supports the contention that dextransucrase could be a promising antigen to study for its anticariogenic potential. more...

Morphological characters currently used to differentiate Caraganaopulens as a species have been found to be insufficient and inconsistent. Through extensive research and comparisons of specimens, it has been revealed that C.opulens and its synonyms have overlapping geographical distributions, and that typification is necessary for C.opulens . Therefore, a lectotype is designated for the name C.opulens , with comments on its typification. Additionally, the current typification status is discussed for all its synonyms, accompanied by substantive notes., (Shabir A. Rather, Anand Kumar, Hongmei Liu.) more...

Artemisia annua L. is a medicinal plant valued for its ability to produce artemisinin, a molecule used to treat malaria. Plant nutrients, especially phosphorus (P), can potentially influence plant biomass and secondary metabolite production. Our work aimed to explore the genetic and metabolic response of A. annua to hardly soluble aluminum phosphate (AlPO 4 , AlP), using soluble monopotassium phosphate (KH 2 PO 4 , KP) as a control. Liquid chromatography-mass spectrometry (LC-MS) was used to analyze artemisinin. RNA sequencing, gene ontology (GO), and the Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were applied to analyze the differentially expressed genes (DEGs) under poor P conditions. Results showed a significant reduction in plant growth parameters, such as plant height, stem diameter, number of leaves, leaf areas, and total biomass of A. annua. Conversely, LC-MS analysis revealed a significant increase in artemisinin concentration under the AlP compared to the KP. Transcriptome analysis revealed 762 differentially expressed genes (DEGs) between the AlP and the KP. GH3, SAUR, CRE1, and PYL, all involved in plant hormone signal transduction, showed differential expression. Furthermore, despite the downregulation of HMGR in the artemisinin biosynthesis pathway, the majority of genes (ACAT, FPS, CYP71AV1, and ALDH1) were upregulated, resulting in increased artemisinin accumulation in the AlP. In addition, 12 transcription factors, including GATA and MYB, were upregulated in response to AlP, confirming their importance in regulating artemisinin biosynthesis. Overall, our findings could contribute to a better understanding the parallel transcriptional regulation of plant hormone transduction and artemisinin biosynthesis in A. annua L. in response to hardly soluble phosphorus fertilizer., (© 2023.

Reference-guided de novo assembly of the Dalbergia congesta chloroplast genome was carried out using whole-genome sequencing data. The newly generated chloroplast genome size had a total length of 156,048 bp and a GC content of 36.1%. The plastome showed the classical quadripartite structure with two inverted repeats regions (IRs; each 25,715 bp) separating the large single-copy region (LSC; 85,456 bp) from the small single-copy region (SSC; 19,162 bp). The plastid genome contained 111 unique genes, including 77 protein-coding genes (CDS), 30 tRNAs, and 4 rRNAs. The phylogenomic analyses based on whole chloroplast genome sequences recovered Dalbergia as a distinct clade of the Papilionoideae, with Dalbergia congesta having a sister relationship to a clade comprising D. fusca and D. cultrata. The newly available plastome sequence will facilitate future genetic and conservational research aiming to protect this economically important but highly threatened legume species., (© 2023.

An unprecedented, one-step strategy for the synthesis of 5-(methylthio)pyridazin-3(2 H )-one derivatives has been developed through iodine triggered deaminative coupling of glycine esters with methyl ketones and hydrazine hydrate in DMSO. These transformations in the absence of hydrazine helped to generate different 3-methylthio-4-oxo-enoates in good yields. Notably, DMSO played multiple roles such as oxidant, methylthiolating reagent, and solvent. more...

The study aimed to compute the effective dose (E) and size-specific dose estimate (SSDE) of routine adult patients undergoing thorax and abdominal computed tomography (CT) imaging and to present their multivariate analysis. All adult thorax and abdominal CT examinations conducted from March 2022 to June 2022 were prospectively included in this study. The Water Equivalent Diameter ( D w ) and SSDE of all the examinations were computed from CT dose index volume ( CTDI vol ) and Dose length product (DLP) displayed on the dose report in the CT console. The multivariate statistical analysis was performed to investigate the correlation of SSDE and E on CTDI vol , D w area of the region of interest (ROI) ( Area ROI ), body mass index (BMI), conversion factor ( f size ) and hounsfield ( HU mean ) number in the ROI at 95% level of significance ( P < 0.05). The linear regression analysis was performed to investigate the dependence of SSDE and E on other parameters for both abdominal and thorax patients. A total number of 135 (Abdomen = 61 and Thorax = 74) measurements were performed. The mean value of effective dose for abdomen and thorax patients was found to be 7.17 ± 3.94 and 4.89 ± 2.16 mSv , respectively. The SSDE was observed to be 13.24 ± 3.61 and 13.04 ± 3.61 mGy for thorax and abdomen respectively. The multivariate analysis suggests that SSDE for abdominal CT is found significantly dependent on CTDI vol , D w and f size with P < 0.05 and E is found to be significantly dependent on DLP, Area ROI , D w and f size at 95% level of confidence for abdominal CT imaging. SSDE for thorax CT was found significantly dependent on BMI, CTDI vol , HU mean , D w and f size at 95% level of confidence. Furthermore, E was observed dependent on DLP at P < 0.05. The linear regression analysis also shows that E is strongly correlated with DLP ( r = 1.0) for both thorax and abdominal CT, further the SSDE was observed strongly correlated with CTDI vol with r = 0.79 and r = 0.86 for abdomen and thorax CT respectively. A strong correlation was observed between BMI and for D w abdominal CT imaging ( r = 0.68). The mean value of SSDE for thorax is slightly greater than abdomen. The average value of effective dose for abdomen and thorax measurements was found to be 7.17 ± 3.94 and 4.89 ± 2.16 mSv and , correspondingly. SSDE for both abdomen and thorax CT is significantly dependent on CTDI vol , D w and f size at 95% level of confidence. The strong correlation was also observed E on DLP and SSDE on CTDI vol for both Abdomen and Thorax CT. The strong dependence of D w on BMI ( r = 0.68) is due to the excessive fat concentration around the stomach and abdomen., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Medical Physics.) more...

Aim: Plant metal tolerance proteins (MTPs) are plant membrane divalent cation transporters that specifically contribute to heavy metal stress resistance and mineral uptake. However, little is known about this family's molecular behaviors and biological activities in soybean., Methods and Results: A total of 20 potential MTP candidate genes were identified and studied in the soybean genome for phylogenetic relationships, chromosomal distributions, gene structures, gene ontology, cis-elements, and previous gene expression. Furthermore, the expression of MTPs has been investigated under different heavy metals treatments. All identified soybean MTPs (GmaMTPs) contain a cation efflux domain or a ZT dimer and are further divided into three primary cation diffusion facilitator (CDF) groups: Mn-CDFs, Zn-CDFs, and Fe/Zn-CDFs. The developmental analysis reveals that segmental duplication contributes to the GmaMTP family's expansion. Tissue-specific expression profiling revealed comparative expression profiling in similar groups, although gene expression differed between groups. GmaMTP genes displayed biased responses in either plant leaves or roots when treated with heavy metal. In the leaves and roots, nine and ten GmaMTPs responded to at least one metal ion treatment. Furthermore, in most heavy metal treatments, GmaMTP1.1, GmaMTP1.2, GmaMTP3.1, GmaMTP3.2, GmaMTP4.1, and GmaMTP4.3 exhibited significant expression responses., Conclusion: Our findings provided insight into the evolution of MTPs in soybean. Overall, our findings shed light on the evolution of the MTP gene family in soybean and pave the path for further functional characterization of this gene family., (© 2023.

Background: Embelia ribes Burm f. (Primulaceae) is a medicinal and vulnerable woody liana distributed throughout India. Embelin, a well-recognized active phytoconstituents in berries, is commonly used in ayurvedic formulations. Due to over-exploitation, the status of the plant is vulnerable. Previous studies on this species mainly focused on its phytochemical analysis, which led to overexploitation and loss of the germplasm., Methods and Results: In the present study, 20 RAPD and 18 ISSR markers were employed to assess genetic divergence in 40 genotypes of E. ribes collected from different parts of the Western Ghats of India. In RAPD analysis, all 40 accessions with 20 RAPD primers amplified 282 fragments, with 83.91% average polymorphism and with an average of 14.10 bands per primer. The size of amplicons varied from 200 to 2500 bp. While, ISSR primers produced 203 fragments of which 161 were polymorphic with an average of 11.28 bands per primer with 73.25% average polymorphism. The size of amplicons ranges from 200 to 2500 bp. RAPD and ISSR markers were also assessed by calculating polymorphic information content (PIC) to discriminate the genotypes; the average PIC value for RAPD, ISSR, and combined RAPD + ISSR markers obtained was more than 0.50 suggesting the informativeness of markers. UPGMA analysis based on Jaccard's similarity coefficient for RAPD, ISSR, and RAPD + ISSR data reveals that 40 accessions of E. ribes were depicted in four clusters. The clustering pattern of all individuals in PCoA analysis agreed with the UPGMA dendrograms, which further confirms the genetic relationships explained by cluster analysis. AMOVA analysis of RAPD, ISSR, and combined marker system revealed variation within the population, ranging from 41 to 44%, and among the population, it ranged from 56 to 59%., Conclusion: The present study provides an optimized method for evaluating the genetic diversity of Embelia ribes using RAPD and ISSR markers which are useful for further sustainable utilization and conservation of natural populations in the Western Ghats of India., (© 2022.

The given method features operational simplicity, excellent functional group tolerance, broad substrate scope, and fast kinetics. Moreover, the method was applied to the synthesis of the natural product alatamide. Notably, DMSO plays three vital roles: a formyl group source, an oxidant, and a solvent. more...

Intercropping cover crops with trees enhance land productivity and improves the soil’s physio-chemical properties while reducing the negative environmental impact. However, there is a lack of quantitative information on the relationships between fine root biomass and available soil nutrients, e.g., nitrogen (N), phosphorus (P), and potassium (K), especially in the rubber-Flemingia macrophylla intercropping system. Therefore, this study was initiated to explore the seasonal variation in fine root biomass and available soil nutrients at different stand ages (12, 15, and 24 years) and management systems, i.e., rubber monoculture (mono) and rubber-Flemingia macrophylla intercropping. In this study, we sampled 900 soil cores over five seasonal intervals, representing one year of biomass. The results showed that the total fine root biomass was greater in 12-year-old rubber monoculture; the same trend was observed in soil nutrients P and K. Furthermore, total fine root biomass had a significant positive correlation with available N (p < 0.001) in rubber monoculture and intercropping systems. Thus, it suggests that fine root growth and accumulation is a function of available soil nutrients. Our results indicate that fine root biomass and soil nutrients (P and K) may be determined by the functional characteristics of dominant tree species rather than collective mixed-species intercropping and are closely linked to forest stand type, topographic and edaphic factors. However, further investigations are needed to understand interspecific and complementary interactions between intercrop species under the rubber-Flemingia macrophylla intercropping system. more...

In the present study, chitosan (CH) based biodegradable films were developed enriched with thyme essential oil (TEO) incorporated with different additives including zinc oxide (ZnO), polyethylene glycol (PEG), nano clay (NC), and calcium chloride (CaCl 2 ) and characterize the postharvest quality of 'collard greens' during refrigerated storage. The results indicated that the incorporation of ZnO/PEG/NC/CaCl 2 in CH-based films significantly decreased water vapor transmission rate, increased tensile strength, and were water soluble and biodegradable in nature. Moreover, CH-TEO based films incorporated with ZnO/PEG/NC/CaCl 2 were significantly effective in reducing physiological weight loss, retained total soluble solids, titratable acidity, and preserved chlorophyll contents as well as showed lesser a* values, suppressed microbial growth, and preserving appearance/sensory quality of collard greens for 24 days than LDPE and other biodegradable films. Our results suggest that CH-based films enriched with TEO and additives such as ZnO/CaCl 2 /NC/PEG are an ecological, environmental friendly, and effective alternative approach to retain shelf life of collard greens during refrigerated storage., (© 2022.

Background: Intestinal ascariasis is considered as state subject in our valley of Kashmir. The aim of our study was to analyse the age, clinical presentation, diagnosis, surgical complications, and management of Ascaris lumbricoides in children and adults., Methods: Total of 312 patients above 2 years of age with definite clinical and radiological diagnosis of intestinal ascariasis and associated complications were included in our study. All our patients received anthelminthic drug (Albenzadole 400 mg stat) after termination of acute phase and attached to our Out-Patient Department for follow-up. Each patient was given second dose of antihelminthic drug at second follow-up visit., Results: Total of 312 subjects included 131 (41.99%) males and 181 (58.01%) females. The highest number of patients was in age group of 6-10 years (46.47%). Colicky abdomen pain was the most common presentation and present in 80.12% patients followed by vomiting (64.1%). Palpable worm bolus was a cardinal sign present in 46.47% of our subjects. Two-hundred sixty-five (84.94%) patients responded uneventfully and were relieved of colic and obstruction after conservative non-operative treatment. Twenty (6.41%) patients underwent enterotomy and evacuation of worms, 2 (0.64%) subjects underwent resection anastomosis, and 8 (2.56%) patients had laparotomy and milking of worms into colon. None of patient expired during the study period., Conclusion: Ascaris lumbricoides is common cause of acute abdomen in our valley attributed to poor hygiene and low socioeconomic background. In patients of high clinical suspicion of worm obstruction, prompt investigations should be advised to reach a definitive diagnosis and prevent the development of complications. Significant efforts must be channelised at political and society levels for the prevention of this disease. Mass deworming programs should be adopted to overcome this menace., (© 2021.

Described are the diverse reactivities of novel, stable, ambident thio-organocesium reagents (bearing electron withdrawing groups) against benzynes. Reactions at reflux temperature predominantly led to the generation of various functionalized stable sulfonium ylides and at 40 °C the same reaction underwent direct c-arylation. Furthermore, lack of internal hydrogen on the cesium reagent helped to produce different ortho-bifunctional arynes in both the reactions. Interestingly, depending on the reactivities of substrates, the one-pot tri-component procedure generated either ylides or σ-bond insertion products., (© 2022 Wiley-VCH GmbH.) more...

Heavy metal (HM) contamination resulting from industrialization and urbanization during the Anthropocene along with plant invasion can severely threaten the growth and adaptation of local flora. Invasive alien plant species generally exhibit a growth pattern consistent with their functional traits in non-contaminated environments in the introduced range. However, it remains unclear whether invasive alien plants have an advantage over native plants in contaminated environments and whether this growth pattern is dependent on the adaptation of their leaf functional traits. Here, we selected two congeneric pairs of invasive alien and native grasses that naturally co-exist in China and are commonly found growing in contaminated soil. To evaluate the effect of cadmium (Cd) on the structural and physiological leaf traits, we grew all four species in soil contaminated without or with 80 mg/kg Cd. Invasive plants contained significantly higher concentrations of Cd in all three organs (leaf, stem, and root). They displayed a higher transfer factor and bioconcentration factor (BCF) of shoot and root than natives, indicating that invasive species are potential Cd hyperaccumulators. Invasive plants accumulated polyphenol oxidase (PPO) to higher levels than natives and showed similar patterns of leaf structural and physiological traits in response to changes in Cd bioconcentration. The quantifiable leaf structural traits of invasive plants were significantly greater (except for stomatal density and number of dead leaves) than native plants. Leaf physiological traits, chlorophyll content, and flavonoid content were also significantly higher in invasive plants than in natives under Cd stress conditions after 4 weeks, although nitrogen balance index (NBI) showed no significant difference between the two species. Chlorophyll fluorescence parameters decreased, except for the quantum yield of photosystem II (ΦPSII) and the proportion of open photosystem II (qP), which increased under Cd stress conditions in both species. However, invasive plants exhibited higher fluorescence parameters than natives under Cd stress, and the decrement observed in invasive plants under Cd stress was greater than that in natives. High Cd adaptation of invasive grasses over natives suggests that invasive plants possess optimal leaf structural and physiological traits, which enable them to adapt to stressful conditions and capture resources more quickly than natives. This study further emphasizes the potential invasion of alien plants in contaminated soil environments within the introduced range. To a certain extent, some non-invasive alien plants might adapt to metalliferous environments and serve as hyperaccumulator candidates in phytoremediation projects in contaminated environments., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Ilyas, Shah, Lai, Sher, Bai, Zaman, Bibi, Koul, Wani, Majrashi, Alharby, Hakeem, Wang and Rather.) more...

An increase in temperature and extreme heat stress is responsible for the global reduction in maize yield. Heat stress affects the integrity of the plasma membrane functioning of mitochondria and chloroplast, which further results in the over-accumulation of reactive oxygen species. The activation of a signal cascade subsequently induces the transcription of heat shock proteins. The denaturation and accumulation of misfolded or unfolded proteins generate cell toxicity, leading to death. Therefore, developing maize cultivars with significant heat tolerance is urgently required. Despite the explored molecular mechanism underlying heat stress response in some plant species, the precise genetic engineering of maize is required to develop high heat-tolerant varieties. Several agronomic management practices, such as soil and nutrient management, plantation rate, timing, crop rotation, and irrigation, are beneficial along with the advanced molecular strategies to counter the elevated heat stress experienced by maize. This review summarizes heat stress sensing, induction of signaling cascade, symptoms, heat stress-related genes, the molecular feature of maize response, and approaches used in developing heat-tolerant maize varieties., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 El-Sappah, Rather, Wani, Elrys, Bilal, Huang, Dar, Elashtokhy, Soaud, Koul, Mir, Yan, Li, El-Tarabily and Abbas.) more...

Objective: Conventional treatments for benign prostatic hyperplasia (BPH) like 5alpha-reductase inhibitors and invasive surgery are associated with some obvious side effects. Conversely, evidence, though limited, has shown that alternative medicines are safer and have potential to improve the lower urinary tract symptoms (LUTS) and quality of life in addition to improving sexual dysfunction in patients with BPH. The current article aimed to include an overview of BPH, different ways of its management, and particularly its appreciation in Greco-Arab (Unani) system of medicine, one of the alternative medicinal systems., Methods: PubMed, Scopus, ScienceDirect, Web of Sciences, Google Scholar databases and classical texts of Greco-Arab medicine were searched for data collection., Results: In Unani system of medicine, BPH, traced under the headings of Waram unuq al-mathana (bladder neck swelling) and Insidad majra-i-mathana (bladder outlet obstruction), has been managed for centuries with herbal medicines yet demanding a comprehensive scientific validation. Among the herbs, Cucurbita pepo , Tribulus terrestris , Urtica dioica , and Linum usitatissimum are worth mentioning., Conclusion: For achieving the goal of LUTS-free ageing men, and safer and cost-effective future management of BPH, Unani herbal medicine could hopefully prove beneficial., Competing Interests: The authors declare no conflict of interest., (© 2022 Editorial Office of Asian Journal of Urology.

The negative solution to the famous problem of 36 officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution, provided the officers are entangled, and construct orthogonal quantum Latin squares of this size. As a consequence, we find an example of the long-elusive Absolutely Maximally Entangled state AME(4,6) of four subsystems with six levels each, equivalently a 2-unitary matrix of size 36, which maximizes the entangling power among all bipartite unitary gates of this dimension, or a perfect tensor with four indices, each running from one to six. This special state deserves the appellation golden AME state, as the golden ratio appears prominently in its elements. This result allows us to construct a pure nonadditive quhex quantum error detection code ((3,6,2))&#95;{6}, which saturates the Singleton bound and allows one to encode a six-level state into a triplet of such states. more...

Gradually rising atmospheric temperature is the vital component of the environment, which is anticipated as the riskiest abiotic stress for crop growth. Nanotechnology revolutionizing the agricultural sectors, notably, zinc oxide nanoparticles (nano-ZnO) has captured intensive research interests due to their distinctive properties and numerous applications against abiotic stresses. Mungbean ( Vigna radiata L.), being a summer crop, is grown all over the world at an optimum temperature of 28-30°C. A rise in temperature above this range, particularly during the flowering stage, can jeopardize the potential performance of the plant. Hence, an outdoor study was performed to evaluate the effect of multiple suspensions of nano-ZnO (0, 15, 30, 45, and 60 mg l -1 ) on physicochemical attributes and yield of mungbean crop under heat stress. Heat stress was induced by fine-tuning of sowing time as: S1 is the optimal sowing time having day/night temperatures <40/25°C and S2 and S3 are late sown that were above >40/25°C during the flowering stage. In vitro studies on Zn release from nano-ZnO by inductively coupled plasma mass spectroscopy (ICPMS) disclosed that the Zn release and particles uptake from nano-ZnO were concentration-dependent. Exogenous foliar application of nano-ZnO significantly upstreamed the production of antioxidants and osmolytes to attenuate the shocks of heat stress in S2 and S3. Likewise, nano-ZnO substantially rebated the production of reactive oxygen species in both S2 and S3 that was associated with curtailment in lipid peroxidation. Adding to that, foliar-applied nano-ZnO inflates not only the chlorophyll contents and gas exchange attributes, but also the seeds per pod (SPP) and pods per plant (PPP), which results in the better grain yield under heat stress. Thus, among all the sowing dates, S1 statistically performed better than S2 and S3, although foliar exposure of nano-ZnO boosted up mungbean performance under both the no heat and heat-induced environments. Hence, foliar application of nano-ZnO can be suggested as an efficient way to protect the crop from heat stress-mediated damages with the most negligible chances of nanoparticles delivery to environmental compartments that could be possible in case of soil application., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Kareem, Saleem, Saleem, Rather, Wani, Siddiqui, Alamri, Kumar, Gaikwad, Guo, Niu and Wang.) more...

Drought is a major environmental threat that affects plant growth and productivity. Strategies to mitigate the detrimental impacts of drought stress on plants are under scrutiny. Nanotechnology is considered an effective tool in resolving a wide range of environmental issues by offering novel and pragmatic solutions. A pot experiment was performed to determine the efficacy of zinc oxide nanoparticles (ZnO NPs) as a foliar application (25 mg L -1 and 100 mg L -1 ) on the growth performance of cucumber subjected to drought stress. Applied ZnO NPs under normal conditions resulted in significant growth and biomass enhancement while reducing drought-induced decline. Photosynthetic pigments, photosynthesis, and PSII activity enhanced due to ZnO NPs application, attaining maximal values at 100 mg L -1 of ZnO NPs. Drought stress restricted growth and biomass buildup in cucumber seedlings by stimulating oxidative stress, which was manifested to excessive buildup of reactive oxygen species (ROS) and peroxidation, thereby decreasing membrane functioning. Plants exposed to ZnO NPs exhibited a reduction in ROS accumulation and lipid peroxidation. The substantial reduction in oxidative damage was manifested with the enhancement of enzymatic and non-enzymatic antioxidant components. The phenol and mineral contents were reduced due to drought stress. In addition, the content of proline, glycine betaine, free amino acids, and sugars increased due to ZnO NPs under normal and drought conditions. Furthermore, the drought-induced decline in the content of phenol and mineral nutrients was mitigated by ZnO NPs foliar application. These findings reveal that exogenous ZnO NPs application may be a pragmatic option in dealing with the drought stress of cucumber seedlings., (Copyright © 2021 Elsevier Ltd.

Three types of honeys viz. Robinia pseudoacacia (RSA), Plectranthus rugosus (PR) and multifloral honey (MF) from Kashmir Himalayas of India were characterized on the basis of physicochemical, antioxidant and FTIR-ATR spectroscopic features. The physicochemical parameters indicated that ash content, electrical conductivity, redness (a*) and yellowness (b*) were higher in MF honey, moisture content, Hydroxymethylfurfural (HMF) and lightness (L*) in PR honey and Water activity (a w ) and proline content in RSA honey ( P  ≤ 0.05). Significantly higher values of total sugar, total reducing sugar and sucrose content was observed in MF honey ( P  ≤ 0.05). The total phenolic content (TPC), total flavonoids, ferric reducing antioxidant power and 1, 1-diphenyl-2-picrylhydrazy-IC 50 (DPPH- IC 50 ) free radical scavenging activity showed that MF honey had significantly higher antioxidant activity ( P  ≤ 0.05). ATR-FTIR analysis demonstrated that the absence of peaks at broad band around 1653.454-1637.656 cm -1 in MF honey, 1185.989-1153.072 cm -1 and 918.570-916.544 cm -1 wavenumbers in PR honey thus clearly discriminating different types of honeys. The results revealed that physico-chemical, antioxidant and spectroscopic characteristics of honey types vary with geographic origin and their floral sources and MF honey have a high therapeutic potential., (© Association of Food Scientists & Technologists (India) 2021.) more...

This study evaluated the impact of xanthan gum (XG), canning and storage on fatty acids (FAs) contents and formation of cholesterol oxidation products (COPs) in low-fat meat product (goshtaba) of Jammu and Kashmir (J&K), India. The FAs composition i.e. saturated FAs, monounsaturated FAs, polyunsaturated FAs and trans FAs during processing and storage showed non-significant difference in all goshtaba products (P > 0.05). The cholesterol content decreased significantly after canning in all products (P < 0.05) while, maximum reduction was observed in high-fat goshtaba (HFC). During storage all products exhibited significant decrease in cholesterol upto 6th month, thereafter showed non-significant variation. The COPs determined were 7-β-OH-ch, 5-ch-3β-ol-7-one and 25-OH-ch. After canning two COPs (7-β-OH-ch, 5-ch-3β-ol-7-one) were produced in all products. But during storage there was formation of 25-OH-ch, increase in 7-β-OH-ch and decrease in 5-ch-3β-ol-7-one and lower COPs were observed in low-fat goshtaba containing 1.5% XG. The results concluded that fat replacer (XG), processing and storage had no significant effect on the FAs compositions of all goshtaba products including HFC. However, cholesterol content exhibited significant variation and minimum reduction in cholesterol and formation of lower COPs were observed in low-fat goshtaba formulated with 1.5% XG., (Copyright © 2020 Elsevier Ltd.

By facilitating the chemical conversion of thiols to thiosulfonates, phosphoramidite/phosphite bearing sp 3 -hybridized carbon serves as an ideal coupling material to forge new connections at room temperature. In this work, a functional group-induced, additive-free, novel, S-P bond-forming approach is presented. This protocol exhibits good functional group tolerance with wide applications that include phosphorylation of cysteine derivatives, development of a one-pot approach to mixed unsymmetrical thiophosphonates, and extension of the concept to different Se-P bonds. Meticulously, our reaction also generated a S-P bond against cyclic 1,2-dithiane-1-dioxide in a byproduct-free manner. These Michaelis-Arbuzov-type reactions are easy to conduct, work efficiently in a reduced reaction time, and are applicable to gram-scale preparation as well. more...

This study investigated physicochemical, glycemic index, pasting and microstructural properties of low glycemic index rice flour (LGIRF) stored in two different packaging materials (low density polyethylene-LDPE and metalized polyester-Met-PE) under accelerated storage conditions (38 ± 2 °C and 90-92% RH) for three months. The different properties were evaluated after every one month. Protein, fat, fibre and carbohydrate content decreased slightly while, water activity, moisture and ash of both control and LGIRF increased significantly with storage (P < 0.05). Total starch, in vitro glycemic index and glycemic load were higher in control and decreased during storage (P < 0.05). However, resistant starch, total sugars, reducing sugars and degree of sweetness in LGIRF exhibited higher, although non-significant variation relative to control during storage. Pasting properties revealed that peak and breakdown viscosities decreased while final and setback viscosities increased during storage (P < 0.05) however holding viscosity and pasting temperature exhibited non-significant variation (P > 0.05). Further, all pasting properties were significantly higher in control except pasting temperature (P < 0.05). All farinographic properties exhibited non-significant difference during storage and were significantly higher in control. Overall, while comparing LDPE and MeT-PE samples non-significant variation was observed in all properties. Microstructural studies showed that integrity of starch granules in LGIRF samples were least altered during storage., (Copyright © 2020 Elsevier B.V. All rights reserved.) more...

Maximally entangled bipartite unitary operators or gates find various applications from quantum information to many-body physics wherein they are building blocks of minimal models of quantum chaos. In the latter case, they are referred to as "dual unitaries." Dual unitary operators that can create the maximum average entanglement when acting on product states have to satisfy additional constraints. These have been called "2-unitaries" and are examples of perfect tensors that can be used to construct absolutely maximally entangled states of four parties. Hitherto, no systematic method exists in any local dimension, which results in the formation of such special classes of unitary operators. We outline an iterative protocol, a nonlinear map on the space of unitary operators, that creates ensembles whose members are arbitrarily close to being dual unitaries. For qutrits and ququads we find that a slightly modified protocol yields a plethora of 2-unitaries. more...

Streptococcus mutans is a common principal causative agent of dental caries. In this communication, we describe that the antibodies raised against purified dextransucrase effectively inhibited the growth of S. mutans. The purified enzyme showed 58-fold enrichment, 17.5% yield and a specific activity of 3.96 units/mg protein. Purified IgG fraction of the antibody showed significant affinity with the antigenic protein. Immunotritation of the enzyme with dextransucrase antibody showed a gradual increase in inhibition of dextransucrase activity. The growth of S. mutans was also inhibited by 85% in the presence of 28 μg of IgG fraction of the antibody. Antibodies also impaired glucosyltransferase activity (72.8%) and biofilm formation by 92.6% in S. mutans. Western blot analysis revealed no cross reactivity with the various tissues of mice, rat, rabbit and humans. Dot blot analysis showed little reactivity with Lactobacillus acidophilus and Staphylococcus aureus and there was no reactivity with other bacterial strains like Enterococcus faecalis, Escherichia coli and Salmonella typhimurium. These findings suggest that antibody raised against dextransucrase exhibit inhibitory effects on the growth of S. mutans and biofilm formation with no reactivity with various mammalian tissues, thus it could be an effective anticariogenic agent. more...

Dextransuccrase (E.C 2.4.1.5) is a key enzyme in S. mutans for the metabolism of sucrose which helps in the adherence and accumulation of bacteria on tooth surface leading to the formation of dental caries. Dextransuccrase resembles in its catalytic properties with the brush boarder sucrase and exhibits pH dependent inhibitory and stimulatory effects in response to Na + . In this communication we studied the effect of monovalent cations on the activity of dextransuccrase from S. mutans . The percentage inhibition of dextransuccrase was 65% at 0.5 mM NaCl which enhanced to 90% at 20 mM sodium concentration. However there was no effect on dextransucrase activity in presence of other monovalent cations (Rb + , Cs + , and K + ) tested. Enzyme activity was enhanced 20-24% in acidic pH but was strongly inhibited (59-89%) around neutral and alkaline pH by 0.5-2.0 mM sodium chloride. Upon dialysis, 86% of enzyme activity was restored to control values. There was no effect of 2 mM NaCl on glucosyltransferase activity of the enzyme. Kinetic studies revealed that enzyme showed biphasic effects in response to Na + ions. At acidic pH the enzyme exhibited mixed type of activation affecting both Vmax and Km, while in alkaline pH, the enzyme showed V- type effect reducing Vmax by 74% without affecting Km. The effects of sodium ions on dextransuccrase activity were specific, thus it can be useful to block its catalytic activity, and reducing the cariogenic potential of S. mutans., Competing Interests: All authors who contributed substantially to the work and participated in the writing of the manuscript, have seen and approved the revised version of this article and no part of the work has been published before.

Risk of massive intraoperative hemorrhage and the difficulty to control it makes the laparoscopic treatment of giant hepatic hemangiomas (GH) a challenge for minimally invasive hepatobiliary surgeons. Symptomatic GHs of more than 20 cm (extremely giant hepatic hemangiomas) are typically treated with an open resection. There is a paucity of literature on laparoscopic resection of extremely giant hepatic hemangiomas. We describe (with video), here, the technical nuances of pure laparoscopic resection of an extremely giant hepatic hemangioma using modified port positions and the anterior approach. more...

Rosemary (REO), mint essential oil (MEO), nisin and lactic acid were incorporated at 0.5% to develop a novel functional packaging film including chitosan pectin and starch polymers (0.75:1.5:0.75 w/w). Inclusion of REO and nisin significantly (p ≤ 0.05) improved water barrier properties (0.014 g.mm/m 2 24h), tensile strength (25.95 MPa) and thermal stability as compared to control. ATR-FTIR spectra and XRD pattern elucidated structural interaction between EO's and biocomposite films. Addition of REO of and nisin increased microsctructural heterogeneity and opacity (2.78). Incorporation of REO and nisin exhibited the highest inhibitory activity against all tested pathogenic strains (Bacillus subtilis, Escherichia coli, and Listeria monocytogenes). The antioxidant properties of biocomposite films were analyzed using reducing power, metal chelation, DPPH and ABTS radical scavenging assays, which enhanced significantly (p ≤ 0.05) with the addition of MEO and REO. This study validated that incorporation of natural additives in active biocomposite films offers promising functional ingredients for packaging materials for various food applications., (Copyright © 2019.

A series of oxo-phenylacetyl (OPAc)-protected saccharides, with divergent base sensitivity profiles against benzoyl (Bz) and acetyl (Ac) were synthesized, and KHSO 5 /AcCl in methanol was identified as an easy, mild, selective, and efficient deprotecting reagent for their removal in the perspective of carbohydrate synthesis. Timely monitoring of AcCl reagent was supportive in both sequential and simultaneous deprotecting of OPAc, Bz, and Ac. The salient feature of our method is the orthogonal stability against different groups, its ease to generate different valuable acceptors using designed monosaccharides, and use of OPAc as a glycosyl donar. more...

Two new species of Fabaceae-Papilionoideae are described and illustrated. Crotalaria suffruticosa from Karul Ghat region of Maharashtra is morphologically close to C. albida and C. epunctata. C. multibracteata from Panhala region of Maharashtra resembles C. vestita. C. suffruticosa differs from C. albida and C. epunctata in its habit, leaf, inflorescence, callosity, keel type, stigma, style morphology and number of seeds/pod. To test if the new species differ from their morphologically most similar species, we measured various traits and performed a Principal Component Analysis (PCA). This analysis shows that the new species differs from similar species in gross morphology for several diagnostic traits and showed correlations between the variables or distance among groups and estimated the contribution of each character. Phylogenetic analyses were also conducted based on nuclear (ITS) and plastid (matK) markers. The analyses revealed nucleotide differences between the new species and their close allies attributing to their distinctiveness. A map and key including all species of Crotalaria from Maharashtra state are provided. Conservation status of the two new species have also been assessed. more...

Vascular complications continue to have a devastating effect on liver transplantation recipients, even though their nature, incidence, and outcome might have actually changed with increasing experience and proficiency in high-volume centers. The aim of this study was to analyze the trends observed in vascular complications with changing protocols in adult and pediatric living donor liver transplantation over 10 years in 2 time frames in terms of nature, incidence, and outcome. It is a retrospective analysis of 391 (group 1, January 2006 to December 2010) and 741 (group 2, January 2011 to October 2013) patients. With a minimum follow-up of 2 years, incidence of hepatic artery thrombosis (HAT) in adults has reduced significantly from 2.2% in group 1 to 0.5% in group 2 (P = 0.02). In group 2, nonsignificantly, more adult patients (75% with HAT) could be salvaged compared with only 25% patients in group 1 (P = 0.12). However, HAT in children had 100% mortality. Incidence of portal vein thrombosis (PVT) in complicated transplants in 2 eras remained the same (P = 0.2) and so has its mortality. The thrombosis rate of the neo-middle hepatic vein was significantly reduced in group 2 (P = 0.01). The incidence of HAT, particularly in adults, has decreased significantly though PVT has continued to puzzle surgeons in complicated transplants. In high-volume centers, increasing proficiency, technical modifications, early diagnosis, and multimodality of treatment is the key to decrease overall morbidity and mortality due to vascular complications.

Carboxymethyl cellulose (CMC) coatings alone and in combination with gamma irradiation was tested for maintaining the storage quality, inhibiting fungal incidence and extending shelf-life of cherry fruit. Two commercial cherry varieties viz. Misri and Double after harvest at commercial maturity were coated with CMC at levels 0.5-1.0 % w/v and gamma irradiated at 1.2 kGy. The treated fruit including control was stored under ambient (temperature 25 ± 2 °C, RH 70 %) and refrigerated (temperature 3 ± 1 °C, RH 80 %) conditions for evaluation of various physico-chemical parameters. Fruits were evaluated after every 3 and 7 days under ambient and refrigerated conditions. CMC coating alone at levels 0.5 and 0.75 % w/v was not found effective with respect to mold growth inhibition under either of the two conditions. Individual treatment of CMC coating at 1.0 % w/v and 1.2 kGy irradiation proved helpful in delaying the onset of mold growth up to 5 and 8 days of ambient storage. During post-refrigerated storage at 25 ± 2 °C, RH 70 %, irradiation alone at 1.2 kGy gave further 4 days extension in shelf-life of cherry varieties following 28 days of refrigeration. All combinatory treatments of CMC coating and irradiation proved beneficial in maintaining the storage quality as well as delaying the decaying of cherry fruit during post-refrigerated storage at 25 ± 2 °C, RH 70 % but, combination of CMC at 1.0 % w/v and 1.2 kGy irradiation was found significantly ( p  ≤ 0.05) superior to all other treatments in maintaining the storage quality and delaying the decaying of cherry fruit. The above combinatory treatment besides maintaining storage quality resulted in extension of 6 days in shelf life of cherry varieties during post-refrigerated storage at 25 ± 2 °C, RH 80 % following 28 days of refrigeration. Above Combination treatment gave a maximum of 2.3 and 1.5 log reduction in yeast and mold count of cherry fruits after 9 and 28 days of ambient and refrigerated storage, thereby ensuring consumer safety. more...

Background: The aim of the present study was to investigate, anti-obesity effect of Aloe vera (AV), and Gymnema sylvestre (GS) whole extract powders administration to high-fat diet (HFD) fed C57BL/6J mice for 12 weeks., Materials and Methods: At the end of experiment, different parameters such as body weight, feed intake, organ weights, fasting blood glucose, oral glucose tolerance test, plasma lipid levels, and expression analysis of adipocytokines were evaluated., Results: At the end of experimental period, oral administration of both herbs showed a significant ( P < 0.05 and P < 0.001) decrease in the plasma glucose and lipid levels in HFD fed mice. In addition, increased in the epididymal fat (E. fat) weight in the HFD group was significantly ( P < 0.05) reduced on GS administration alone. Finally, quantitative mRNA expression analysis of adiponectin gene was significantly up-regulated in AV supplementation. Further, no effect was observed with the both herbs on pro-inflammatory cytokines (interleukin 6 and tumor necrosis factor-a) in the E. fat tissue of HFD fed group., Conclusions: The anti-obesity and other metabolic studies depend on the type of diet, different parts of herbal extractions, and animal models used. Further studies are required in this area to strengthen the anti-obesity effects of herbs with active component, and it can be used a pro-drug instead of whole extract., Competing Interests: Conflicts of Interest: None declared. more...

The physicochemical, oxidative, texture and microstructure properties were evaluated for low fat meat emulsions containing varying levels of guar/xanthan gum mixture (1:1 ratio) as a fat substitute. Partial replacement of fat with guar/xanthan gum resulted in higher emulsion stability and cooking yield but lower penetration force. Proximate composition revealed that high fat control had significantly higher fat and lower moisture content due to the difference in basic formulation. Colour evaluation revealed that low fat formulations containing gum mixture had significantly lower lightness and higher yellowness values than high fat control formulation. However non-significant difference was observed in redness values between low fat formulations and the high fat control. The pH values of the low fat formulations containing gum mixture were lower than the control formulations (T0 and TC). The MetMb% of the high fat emulsion formulation was higher than low fat formulations. The significant increase of TBARS value, protein carbonyl groups and loss of protein sulphydryl groups in high fat formulation reflect the more oxidative degradation of lipids and muscle proteins during the preparation of meat emulsion than low fat formulations. The SEM showed a porous matrix in the treatments containing gum mixture. Thus, the guar/xanthan gum mixture improved the physicochemical and oxidative quality of low fat meat emulsions than the control formulations. more...
