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.
