Abstract
This study investigated the role of dietary prebiotic mannan-oligosaccharides (MOS), and probiotic Bifidobacterium bifidum (BFD) in lipid metabolism, deposition, and consequent health indices in broiler chicken. The supplementation of 0.2% MOS along with either 106 or 107 CFU BFD/g feed resulted in downregulation of Acetyl-CoA carboxylase, fatty acid synthase, sterolregulatory element binding protein-1, and apolipoprotein B100; and up-regulation of peroxisome proliferator activated receptor-α AMP-activated protein kinase α-1, and stearoyl CoA (∆9) desaturase-1 hepatic expression in broiler chicken. The birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed depicted lower body fat percentage, palmitic acid, stearic acid, and saturated fatty acid contents, whereas, higher palmitoleic acid, oleic acid, and MUFA contents were observed. The ∆9-desaturase indices of chicken meat have shown higher values; and elongase index (only thigh) and thioesterase index have shown lower values in birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed. The meat health indices such as Polyunsaturated fatty acids (PUFA)/Saturated fatty acids (SFA) ratio, Mono-saturated fatty acids (MUFA)/SFA ratio, unsaturated fatty acids (UFA)/SFA ratio, hypocholesterolemic/hypercholesterolemic fatty acid ratio, saturation index, atherogenic index, thrombogenic index, and hypercholesterolemic fatty acid content were positively improved in birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed. Similarly, the birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed have shown lower serum triglyceride and total cholesterol levels along with higher high density levels and improved serum health indices cardiac risk ratio, atherogenic coefficient, and, atherogenic index of plasma.

Abstract
The effects of dietary Lactobacillus acidophilus (LBA) and mannan-oligosaccharide (MOS) supplementation on lipid metabolism and consequent lipid profile and health indices in broiler chicken were investigated in this study. Supplementation of 0.2% MOS along with either 106 or 107 LBA/g feed in broiler chicken downregulated hepatic expression of genes involved in lipogenesis, and upregulated expression of lipolytic genes. It caused decline of lipogenesis and increase of lipid oxidation which resulted in lower carcass fat content. None of the genes studied influenced fatty acid profile of chicken meat except the expression of stearoyl CoA (Δ9) desaturase-1 (SCD-1) whose upregulation increased monounsaturated fatty acid (MUFA) content at the cost of saturated fatty acid (SFA) content. The lipid metabolism indices of chicken meat such as ∆9 desaturase index (DI) increased in birds supplemented with 0.2% MOS along with either 106 or 107 CFU LBA/g feed, whereas no effect was observed on ∆5 + ∆6 DI. The supplementation of 0.2% MOS along with either 106 or 107 CFU LBA/g feed in birds improved the health indices of chicken meat due to upregulation of SCD-1 expression. The supplementation of 0.2% MOS along with either 106 or 107 CFU LBA/g feed in broiler chicken produced hypocholesterolemic and hypolipidemic effects with improved serum cardio-protective indices.

Abstract
This study investigated the effects of dietary Bifidobacterium bifidum (BFD) and mannan-oligosaccharide (MOS), as a synbiotic, on the production performance, gut microbiology, serum biochemistry, antioxidant profile and health indices of broiler chicken. Six dietary treatments were T1 (negative control), T2 (positive control-20 mg antibiotic BMD kg-1 diet; BMD: bacitracin methylene disalicylate), T3 (0·1% MOS + 106 CFU BFD per g feed), T4 (0·1% MOS + 107 CFU BFD per g feed), T5 (0·2% MOS + 106 CFU BFD per g feed) and T6 (0·2% MOS + 107 CFU BFD per g feed). Significantly (P < 0·01) better growth performance and efficiency was observed in birds supplemented with 0·2% MOS along with 106 CFU BFD per g of feed compared to BMD and control birds. Supplementation with 0·2% MOS along with either 106 or 107 CFU BFD per g feed reduced (P < 0·01) the gut coliform, Escherichia coli, total plate count, and Clostridium perfringens count and increased the Lactobacillus and Bifidobacterium count. Significantly (P < 0·01) higher serum and liver antioxidant enzyme pool, serum HDL cholesterol and lower serum glucose, triglyceride, total cholesterol, cardiac risk ratio, atherogenic coefficient and atherogenic index of plasma were observed in birds supplemented with 0·2% MOS along with 106 CFU BFD per g of feed compared to control or BMD supplemented birds. Better production performance, gut microbial composition, serum biochemistry, antioxidant profile and health indices were depicted by broiler chicken supplemented with 0·2% MOS and 106 CFU BFD per g of feed.

Abstract
The present study investigated the effects of Lactobacillus acidophilus (LBA) and mannan-oligosaccharides (MOS) supplementation on the production performance, serum biochemistry, antioxidant profile, health indices, meat quality, and lipid oxidative stability of broiler chicken. A total of 252 commercial broiler chickens at 1 d old of uniform body weight were randomly allocated to 6 maize-soybean-based dietary treatments: T1 (control diet), T2 ( antibiotic bacitracin methylene di-salicylate [BMD] at 20 mg/kg diet), T3 (MOS at 0.1% + LBA at 106 CFU/g feed), T4 (MOS at 0.1% + LBA at 107 CFU/g feed), T5 (MOS at 0.2% + LBA at 106 CFU/g feed), and T6 (MOS at 0.2% + LBA at 107 CFU/g feed). Each treatment was assigned to 6 replicates of 7 birds. The samples for meat quality and serum biochemistry analysis were taken from 12 birds per treatment (2 birds/replicate). The results revealed better (P < 0.01) growth performance and production efficiency of birds fed either T5 or T6 diet compared to control or BMD supplemented diet and BMD-supplemented birds superseded the control birds. Higher (P < 0.01) serum and liver antioxidant enzyme activities, meat antioxidant capacity (2, 2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid [ABTS] and 1, 1-diphenyl-2-picrylhydrazyl [DPPH] assays], serum total protein, high-density lipoproteins (HDL) cholesterol (P < 0.05), and globulin levels (P < 0.01) were observed in birds fed either T5 or T6 diet compared to control or BMD supplemented birds, whereas, lower lipid oxidation (P < 0.01), cardiac risk ratio, atherogenic coefficient, atherogenic index of plasma, serum glucose, triglyceride, total cholesterol levels (P < 0.01), and serum albumin-to-globulin ratio (P < 0.05) were observed in the chickens. The pH of meat from birds fed T4, T5 or T6 diet was lower (P < 0.01) compared to control and other treatments. The extract release volume (ERV), water holding capacity (WHC), and protein content of meat were higher (P < 0.05) in birds fed either T5 or T6 diet compared to control or BMD supplemented birds. Thus, it was concluded that the supplementation of 0.2% MOS along with LBA at 106 CFU/g is optimum for better growth performance, serum biochemistry, antioxidant profile, health indices, meat quality, and lipid oxidative stability of broiler chickens.

Abstract
BACKGROUND Sexually transmitted infections (STIs), like Chlamydia trachomatis and Neisseria gonorrhoeae (CT and NG, respectively) are linked to an important sexual and reproductive health (SRH) burden worldwide. Behavior is an important predictor for SRH, as it dictates the risk for STIs. Assessing the behavior of a population helps to assess its risk profile. METHODS Study participants were recruited at a gynecology outpatient department (OPD) in the Allahabad district in Uttar Pradesh India, and a questionnaire was used to assess demographics, SRH, and obstetric history. Patients provided three samples (urine, vaginal swab, and whole blood). These samples were used to identify CT and NG using PCR/NAAT and CT IgG ELISA. RESULTS A total of 296 women were included for testing; mean age was 29 years. No positive cases of CT and NG were observed using PCR/NAAT. A 7% (22/296) positivity rate for CT was observed using IgG ELISA. No positive association was found between serology and symptoms (vaginal discharge, abdominal pain, dysuria, and dyspareunia) or adverse pregnancy outcomes (miscarriage and stillbirth). Positive relations with CT could be observed with consumption of alcohol, illiteracy, and tenesmus (p-value 0.02-0.03). DISCUSSION STI prevalence in this study was low, but a high burden of SRH morbidity was observed, with a high symptomatic load. High rates of miscarriage (31%) and stillbirth (8%) were also observed among study subjects. No associations could be found between these ailments and CT infection. These rates are high even for low- and middle-income country standards. CONCLUSION This study puts forward high rates of SRH morbidity, and instances of adverse reproductive health outcomes are highlighted in this study, although no associations with CT infection could be found. This warrants more investigation into the causes leading to these complaints in the Indian scenario and potential biases to NAAT testing, such as consumption of over-the-counter antimicrobials.

Abstract
microRNAs (miRNAs) are a class of small non-coding RNAs that play key roles in post transcriptional gene regulation that influence various fundamental cellular processes, including the cellular responses during environmental stresses. However, perusal of literatures revealed few reports on the differential expression of miRNA during thermal stress in Indian native (Bos indicus) cattle breeds. The present investigation aimed to identify differentially expressed miRNAs during thermal stress in Sahiwal (Bos indicus) dairy cattle breed of India, adapted with tropical climate over a long period of time. Stress responses of the animals were characterized by determining various physiological as well as biochemical parameters and differential expression profile of major heat shock protein genes. Ion Torrent deep sequencing and CLC-genomic analysis identified a set of differentially expressed miRNAs during summer and winter seasons. Most of the identified differentially expressed miRNAs were found to target heat shock responsive genes especially members of heat shock protein (HSP) family. Real-time quantification-based analysis of selected miRNAs revealed that bta-mir-1248, bta-mir-2332, bta-mir-2478, and bta-mir-1839 were significantly (p < 0.01) over expressed while bta-mir-16a, bta-let-7b, bta-mir-142, and bta-mir-425 were significantly (p < 0.01) under expressed during summer in comparison to winter. The present study enlists differentially expressed miRNAs at different environmental temperatures in Sahiwal (Bos indicus) that may be importance for further understanding the role of miRNAs on thermo-regulatory mechanisms.

Abstract
Chlamydia trachomatis (hereafter CT) is Gram-negative, obligate intracellular pathogen. It causes the world's most common non-viral sexually transmitted disease. India is home to the world's greatest burden of infectious diseases, yet information on prevalence rates of CT is scarce. This article systematically reviews the literature for the prevalence rates and testing methods in India. A total of 27 studies were included. Four main patients groups (symptomatic women, infertile women, pregnant women and asymptomatic population groups) could be identified with varying rates of CT (0.1%-32% using PCR, 2.4%-75% using ELISA serology). Most of the studies originated from urban settings, 11 of them from New Delhi. In-house PCR was the most common diagnostic technique used generating the following ranges in prevalence for the four group studies: symptomatic women 10%-50%, pregnant women 0.1%-2.5% and asymptomatic populations 0.9%-24.5%. The rates among infertile women were 9%-68% based on serology results. The prevalence rates featured in this paper are in line with other locations across the Indian subcontinent. This review highlights the extreme heterogeneity in the limited studies available in India on CT and the need for standardized guidelines for diagnosis and management of CT in India. The availability of resources should be considered in the formulation of recommendations.

Abstract
Environmental temperature is one of the important abiotic factors that influence the normal physiological function and productive performance of dairy cattle. Temperature stress evokes complex responses that are essential for safeguarding of cellular integrity and animal health. Post-transcriptional regulation of gene expression by miRNA plays a key role cellular stress responses. The present study investigated the differential expression of miRNA in Frieswal (Holstein Friesian × Sahiwal) crossbred dairy cattle that are distinctly adapted to environmental temperature stress as they were evolved by using the temperate dairy breed Holstein Friesian. The results indicated that there was a significant variation in the physiological and biochemical indicators estimated under summer stress. The differential expression of miRNA was observed under heat stress when compared to the normal winter season. Out of the total 420 miRNAs, 65 were differentially expressed during peak summer temperatures. Most of these miRNAs were found to target heat shock responsive genes especially members of heat shock protein (HSP) family, and network analysis revealed most of them having stress-mediated effects on signaling mechanisms. Being greater in their expression profile during peak summer, bta-miR-2898 was chosen for reporter assay to identify its effect on the target HSPB8 (heat shock protein 22) gene in stressed bovine PBMC cell cultured model. Comprehensive understanding of the biological regulation of stress responsive mechanism is critical for developing approaches to reduce the production losses due to environmental heat stress in dairy cattle.

Abstract
The purpose of this study is to develop a novel Reverse Transcriptase Loop-mediated isothermal amplification (RT-LAMP) based assay for in vitro profiling of heat shock protein 70 (Hsp70) in bovine peripheral blood mononuclear cell (PBMC) culture model utilizing the absorbance level of magnesium pyrophosphate-a by-product of LAMP reaction. A set of bovine Hsp70 specific RT-LAMP primers were designed to detect the differential absorbance level of magnesium pyrophosphate by-product which signifies the degree of Hsp70 amplification from cDNA of thermally induced cultured cells at different recovery periods. The study revealed significant (P < 0.05) correlation between absorbance level and the fold change of Hsp70 transcripts at different kinetic intervals of heat stress recovery in bovine PBMC cell culture models. RT-LAMP based absorbance assay can be used as an indicator to measure the degree of bovine Hsp70 transcripts produced during thermal stress and can be used as an alternative to the traditional Real time PCR assay. Developed RT-LAMP assay can be used as a cost-effective method for profiling of bovine HSP70 gene.

Abstract
In globalisation of business, Knowledge Management (KM) plays an important role in Supply Chain (SC) to create, build and maintain competitive advantage through utilisation of knowledge and through collaborative practices. Literature review have suggested the performance of KM adoption in SC may be affected by various influencing factors but it is always difficult for the practitioners to improve all aspects at the same time. The aim of this study is to identify Critical Success Factors (CSFs) of KM adoption in SC. This study presents a favourable method combining fuzzy set theory and the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method to segment the critical factors for successful KM adoption in SC. The empirical case study analysis of an Indian hydraulic valve manufacturing organisation is conducted to illustrate the use of the proposed framework for identifying the CSFs of KM adoption in SC. According to the results of the empirical study, six CSFs of KM adoption in SC are identified out of 25 influencing factors, these are top management support, communication and collaboration techniques, employee involvement, employee training and education, communication among the SC members and trustworthy teamwork to exchange knowledge within SC which will help to improve effectiveness and efficiency of KM adoption in SC. The decision makers can apply a phased implementation of these CSFs to ensure the effective KM adoption in SC under the constraints of available resources. This proposed method provides a more accurate, effective and systematic decision support tool for identifying CSFs of KM adoption in SC.

Abstract
The objective of this paper is to investigate the similarities and dissimilarities in Knowledge Management (KM) practices in the supply chain (SC) among different selected sectors of Indian manufacturing organisations, through formulation and testing of some hypotheses. A questionnaire-based survey was conducted on four sectors, namely, automobile, engineering, process and fast moving consumer goods (FMCG). It is observed from this study that selected sectors do not significantly differ on types of SC knowledge and KM use in various SC performance indicators. It is also observed that selected sectors differ on use of KM in different SC functional areas and various supplier measurement criteria. The analysis reveals that selected sectors have fundamental similarities and dissimilarities in their operations and functioning. This might be the reason for the similarities and dissimilarities found in their KM practices in SC.

Abstract
The purpose of this paper is to present an approach to successful KM implementation by understanding the dynamics among various knowledge management barriers (KMBs) that hinder the implement of KM in organisations. Using interpretive structural modeling (ISM), the research presents a hierarchy-based model and the mutual relationship among the KMBs. The research shows that there is a group of KMBs having high driving power and low dependence which require maximum attention and are of strategic importance. Another group consists of those KMBs which have high dependence and low driving power which necessitate the resultant actions. This categorisation provides a useful tool to top management to differentiate between independent and dependent KMBs and their mutual relationships which would help them to focus on those key KMBs that are most significant for effective KM implementation. Arrangement of KMBs in a hierarchy and the categorisation into driver and dependent categories is an exclusive effort in the area of KM implementation.

Abstract
Several herbal plants such as Chinese herb Rhizoma Coptidis have been reported to possess antidiabetic activity. Berberine is its major active constituent and functions as an insulin sensitizer and insulin secretagogue. It has been reported to modulate several signaling pathways and targets. The objective of the current study is to investigate if berberine can function as a ligand of fatty acid receptor GPR40, which stimulates glucose dependent insulin secretion. Towards this objective, a mammalian cell line with stable overexpression of GPR40 was generated and characterized. Berberine stimulated calcium mobilization with an EC(50) of 0.76 microM in this GPR40 overexpressing cell line. Further, berberine stimulated glucose dependent insulin secretion from rat pancreatic beta cell line. This suggests that berberine functions as an agonist of fatty acid receptor GPR40 and might be a novel antidiabetic mechanism of action for berberine.

Abstract
Protein tyrosine phosphatases (PTPs) play multiple roles in many physiological processes. Over-expression of the PTPs has been shown to be associated with cellular toxicity, which may also lead to the deletion of the respective gene from stable cell clones. We also observed that PTP-1B over-expression in CHO and HEK293 stable cell clones led to cytotoxicity and low revival rates during clone generation and maintenance. To address these issues, bacmid transposition technology was utilized to generate recombinant PTP-1B baculovirus, and Spodoptera frugiperda (Sf9 and Sf21) insect cell lines were infected with the virus. The data obtained on expression and activity of the PTP-1B highlights clear advantage of the recombinant baculovirus-insect cell expression system over the mammalian cell line technique due to increase in enzyme activity, strongly inhibited by phosphatase specific inhibitor RK682. Possible application of the expression system for producing active enzymes in bulk quantity for a new drug discovery is also discussed.

Abstract
Diaeretiella rapae is an important parasitoid of cabbage aphid Diel variation in emergence mating and oviposition of D rapae was studied in the laboratory to understand the biology and behaviour of the parasitoid The emergence of the parasitoid was recorded hourly in two bioassay rooms set up at 22 2C with 16 h photoperiod from 08002400 hours or from 18001000 hours Greatest emergence was found during the early photophase The parasitoids that emerged during the scotophase did not mate until the following photophase Unmated females that emerged during the scotophase had a lower incidence of host attack and oviposition during the dark However the parasitoids became active and had a greater incidence of mating and oviposition when they were brought into the light even during the scotophase This research suggests that light triggers parasitoid activity and that the parasitoids lose their reproductive fitness if they emerge in the scotophase

Abstract
Closed-form analytical solutions are presented for the angular displacement, velocity and acceleration of motion-sensing filiform hairs exposed to airflow pulsations of short time duration. The specific situations of interest correspond to a spider intentionally moving towards a cricket, or an insect unintentionally moving towards or flying past a spider. The trichobothria of the spider Cupiennius salei and the cercal hairs of the cricket Gryllus bimaculatus are explored. Guided by earlier work, the spatial characteristics of the velocity field due to a flow pulsation are approximated by the local incompressible flow field due to a moving sphere. This spatial field is everywhere modulated in time by a Gaussian function represented by the summation of an infinite Fourier series, thus allowing an exploration of the spectral dependence of hair motion. Owing to their smaller total inertia, torsional restoring constant and total damping constant, short hairs are found to be significantly more responsive than long hairs to a flow pulsation. It is also found that the spider trichobothria are underdamped, while the cercal hairs of the cricket are overdamped. As a consequence, the spider hairs are more responsive to sudden air motions. Analysis shows that while two spiders of different characteristic sizes and lunge velocities can generate pulsations with comparable energy content, the associated velocity fields display different patterns of spatial decay with distance from the pulsation source. As a consequence, a small spider lunging at a high velocity generates a smaller telltale far-field velocity signal than a larger spider lunging at a lower velocity. The results obtained are in broad agreement with several of the observations and conclusions derived from combined flow and behavioural experiments performed by Casas et al. for running spiders, and by Dangles et al. for spiders and a physical model of spiders lunging at crickets.

Abstract
AIMS To compare the postprandial lipid responses in subjects with prediabetes (IFG and IGT), newly detected diabetes mellitus (NDDM) and normal glucose tolerance (NGT). METHODS Postprandial lipid responses to a standard oral fat challenge was studied in forty-four subjects who were divided after an OGTT into NGT, pure impaired fasting glucose (PIFG), pure impaired glucose tolerance (PIGT) and NDDM. RESULTS There was a significantly higher postprandial triglyceride (PPTg) response with a higher PPTg area under curve (p=0.004) and peak PPTg levels (p=0.003) in patients with NDDM but not with either PIFG (p>0.05) or PIGT (p>0.05) when compared with NGT. Overall, PPTg responses correlated significantly with fasting plasma glucose (p=0.001) and 2h plasma glucose (p=0.001) but not with age, sex, body mass index, waist, or insulin resistance. CONCLUSION Subjects with newly detected diabetes mellitus displayed postprandial hypertriglyceridemia after a standard oral fat meal challenge while no such abnormality could be demonstrated in subjects with IFG or IGT. This defect is probably related to glycemic status and insulin resistance.

Abstract
Deletion, rearrangement, or amplification of sequences mapping to chromosome 8 are frequently observed in human prostate and other tumors. However, it is not clear whether these events alter the transcriptional activity of the affected genes. To examine this question, we have utilized oligonucleotide microarray technology and compared the transcriptional patterns of normal human prostate tissues and five immortalized cell lines carrying either two normal chromosomes 8 or one normal and one derivative chromosome 8. Comparison of the transcriptional profiles of the tissues and cell lines identified 125 differentially expressed transcripts specific to chromosome 8, with 46 transcripts mapping to 8p and 79 transcripts mapping to 8q. The majority of genes mapping to 8p (44/46, 96%) were transcriptionally down-regulated in cells hemizygous for 8p, whereas the majority of genes mapping to 8q (58/79, 73%) were up-regulated in cells carrying three copies of 8q. Moreover, hemizygous alleles on 8p exhibited sub-haploinsufficient transcript levels for several genes that could be induced to haploinsufficient levels under hypomethylating conditions, suggesting that epigenetic regulation is a common mechanism for gene silencing in cells deleted for one copy of 8p. The results of these studies clearly demonstrate that alterations of gene copy number and transcriptional activity are directly correlated in cell lines harboring derivative chromosomes 8, and that these events are commonly observed during cellular immortalization in vitro.

Abstract
Deletion or rearrangement of sequences that map to the short arm of chromosome 8 (8p) are frequently associated with human prostate tumorigenesis. These losses often involve the entire short arm of chromosome 8 or very large regions of distal or proximal 8p, and several putative tumor suppressor genes mapping to 8p have been described. However, the mechanism responsible for 8p loss during prostate tumorigenesis has not been elucidated. In this study, we report data obtained using array comparative genomic hybridization and spectral karyotyping, which demonstrate successive translocation and deletion events responsible for loss of one copy of 8p in transformed human prostate epithelial cells. Moreover, this loss was accompanied by a pronounced transcriptional downregulation of genes mapping to the remaining copy of 8p and enhanced expression of traits associated with neoplastic transformation. Taken together, these studies illustrate a potential mechanism and functional role for 8p loss in human prostate tumorigenesis.
