Probiotic properties of the riboflavin producing Lactobacillus fermentum strain isolated from yoghurt sample
No full textThe probiotic properties of the riboflavin producing lactic acid bacterium, Lactobacillus fermentum MTCC 8711 were evaluated. The strain was resistant to the acidic environment with the pH of 3.5 and more than 100% survivability of the cells was observed after 4 h. Similarly, 85% survivability was observed in the presence of 0.3% (w/v) bile salts. The strain exhibited β- galactosidase activity by blue colored colony formation in the MRS agar plates with X-gal and IPTG. Further, it was found to be a medium acidifier with a DpH value of 0.96 after 5 h of growth. The strain was also able to reduce the cholesterol up to 50% in the presence of cholesterol and bile salts. Since the strain possesses the basic properties of the probiotics and produces riboflavin, it could be considered as a better starter culture in the fermented food industry. Probiotic properties of the riboflavin producing Lactobacillus fermentum strain isolated from yoghurt sampleS.

Uncovering and recovering the popular romance novel
No full textUniversity of Minnesota Ph.D. dissertation. December 2008. Major: English. Advisor: Dr. Timothy Brennan. 1 computer file (PDF); v, 373 pages, appendix.Popular romance novels are a twentieth- and twenty-first century literary form defined by a material association with pulp publishing, a conceptual one with courtship narrative, and a brand association with particular author-publisher combinations. The theme of romantic love in romance novels forms the basis of a drama involving the extra-private worlds of the protagonists (financial, civic, and familial). The framework of the romantic relationship allows the genre to study the challenges these spheres face over the twentieth and twenty-first centuries. A comprehensive look at the genre's history and diversity, as well as its reception in different readership communities, undergirds this analysis of three tropes involving the romance hero--capitalist, soldier, and heterosexual. The analysis proves the genre's struggle with an economic, political, and social ideology that has gathered force over the last hundred years. Though popular as well as academic critiques of the genre disparage its formulaic sexual content or its attachment to the ideology of middle class morality, its very nature as "commodity literature" helps challenge conservative thought on capitalism, national defense strategies, and sexual orientation.
The dissertation also considers the impact of the dust jackets and paperback covers of romance novels on non-romance readers. A survey of this material history suggests that it has contributed to derogatory opinions on the genre; in particular, the genre has been indicted because of the "bodice-ripper" covers that adorn many romance novels rather than for the actual content. A look at reader and author discussions on the genre, alongside textual analysis of selected works, proves that romance fiction is not fixated on a clichéd plot and descriptions of sexual intercourse; it involves complex themes that are disguised as stereotypical genre elements. Readers' online debates demonstrate how this romance "formula," albeit a function of the genre's commodification, engages them in addressing quandaries related to societal preoccupations. The concluding study of romance reading in India further supports the possibility of multiple, even liberating, readings that can empower romance readers.Kamble, Jayashree. (2008).

Measuring Equity Share Related Risk Perception of Investors in Economically Backward Regions
No full textRisk perception is an idiosyncratic process of interpretation. It is a highly personal process of making a decision based on an individual’s frame of reference that has evolved over time. The purpose of this paper is to find out the risk perception level of equity investors and to identify the factors influencing their risk perception. The study was conducted using a stratified random sampling design of 358 investors. It was found that the overall risk perception level of equity investors is moderate and that the main factors affecting their risk perception are information screening, investment education, fear psychosis, fundamental expertise, technical expertise, familiarity bias, information asymmetry, understanding of the market, etc. Considering the above findings, efforts should be made to bring people with a high risk perception to the low risk perception category by providing them with training to handle or manage high-risk scenarios which will help in promoting an equity-investment culture
Modulation of immune responses in stress by Yoga
No full textStress is a constant factor in today′s fastpaced life that can jeopardize our health if left unchecked. It is only in the last half century that the role of stress in every ailment from the common cold to AIDS has been emphasized, and the mechanisms involved in this process have been studied. Stress influences the immune response presumably through the activation of the hypothalamic-pituitary adrenal axis, hypothalamic pituitary-gonadal axis, and the sympathetic-adrenal-medullary system. Various neurotransmitters, neuropeptides, hormones, and cytokines mediate these complex bidirectional interactions between the central nervous system (CNS) and the immune system. The effects of stress on the immune responses result in alterations in the number of immune cells and cytokine dysregulation. Various stress management strategies such as meditation, yoga, hypnosis, and muscle relaxation have been shown to reduce the psychological and physiological effects of stress in cancers and HIV infection. This review aims to discuss the effect of stress on the immune system and examine how relaxation techniques such as Yoga and meditation could regulate the cytokine levels and hence, the immune responses during stress
Awareness about equity investment among retail investors: a kaleidoscopic view
No full text
Purpose
The purpose of this paper is to systematically review the literature published on the various aspects of awareness about equity investment. The paper highlights the major issues and aspects with respect to equity investment awareness. It also aims to raise specific questions for future research.
Design/methodology/approach
The study is based on secondary information collected primarily through the review of existing literature.
Findings
It is found that the important determinants of equity awareness are demographic, socio-economic and psychological factors. Financial well-being is attributable largely to financial awareness. Growth of the financial market can be credited to equity awareness. Equity awareness enables an investor to make better financial decisions, to appreciate their rights and responsibilities and to understand and manage the risk as an investor.
Practical implications
Policy makers can design the equity awareness campaign considering the different demographic and socio-economic factors. While designing such a campaign, the impact and importance of equity awareness should be illustrated, considering their demographic and socio-economic profile.
Originality/value
This study is the first one using the literature review method in the area of equity investment awareness, in particular, and financial awareness in general. This paper will be useful to researchers, academicians and those working in the area of equity investment awareness and in their understanding about the various aspects of awareness about equity investment. The paper is first of its kind, hence original in nature.

MOLECULAR CHARACTERIZATION OF FUSARIUM OXYSPORUM F. SP. CICERI USING SCAR MARKERS
No full textA study was development of putative SCAR markers from monomorphic bands of RAPD and ISSR primers. The races selected for studies were Type Race-1 (Hyderabad and Akola), Type Race-2, (Kanpur), Type Race-3, (Gurdaspur), Type Race-4 (New Delhi and Jabalpur). Primers used for developing SCAR marker for Fusarium oxysporum f.sp. ciceri were ISSR (GA) 8 YT ,(ATG) 6 ,(GA) 8 T) and RAPD OPA13 OPA18 and OPB14. These primers showed the monomorphic bands, these can be used for development of the putative of SCAR (Sequence Characterized Amplified Regions) markers for identification of Fusarium oxysporum f.sp.ciceri. The amplicon size 600 bp(ATG) 6 ,700 bp (GA) 8 YT and 650 bp of ISSR and 750 bp(OPA18),1.4 kb (OPB14),1500 and 800 bp of OPA 13 were eluted, isolated, confirmed and sequenced. The primers were designed with the sequenced information of these two fragments using primer.3.software and putative SCAR markers were developed. These set of markers were validated against the isolates of the pathogen collected from different locations of India representing various races of the pathogen. Races 1and 4 showed close virulence patterns on chickpea differentials
Journal of Proteomics & Bioinformatics- Open Access www.omicsonline.com Research Article JPB/Vol.1/November 2008 Correlation between the Sucrose Synthase Protein Subfamilies, Variations in Structure and Expression in Stress-derived
No full textCopyright: © 2008 Jayashree B, et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Sucrose synthase is a key regulatory protein, and a potential biomarker for abiotic stress response in plants. These metabolic enzymes have been extensively examined for their varied functional roles. The upregulation of this P i- and adenylate-independent glycolytic enzyme in different environmental contexts has also been extensively characterized. Here we present an analysis of the evolutionary features of sucrose synthases in an effort to correlate variations in sequence to the structure and function of this protein and its potential implication for the stress response mechanism in plants as evidenced from transcript distribution studies. An analysis of the evolutionary characteristics of this enzyme is useful given the role of this protein in sugar sensing, sugar import to sink tissues and plant development. Based on the secondary structural features of sucrose synthases and mapping of sequence variations in the context of the fold of these proteins, we note evolutionarily conserved amino acids of potential functional significance. In addition, we also observe the presence of target peptides i

Evaluation of Homocysteine, Lipoprotein(a) and Endothelin as diagnostic markers of Coronary Artery Disease in Indian population
No full textIndians have been reported to have high prevalence rates of coronary artery disease (CAD) even in the absence of traditional risk factors. The objective of this study was to assess the role of endothelin, lipoprotein(a), homocysteine and lipid profile as markers of CAD in Indian population. It was a hospital based observational case-control study, which included 60 documented patients of CAD, and 50 age and sex matched controls. Routine biochemical parameters were performed. Lipoprotein(a), homocysteine and endothelin levels were estimated by enzyme linked immunosorbent assay. The levels of endothelin (9.78±0.40 pg/ml vs. 7.86±0.31 pg/ml), lipoprotein(a) (51.42±1.71 mg/dl vs. 36.26±1.21 mg/dl), homocysteine (21.31±1.22 μmol/L vs. 10.41±0.844 μmol/L) and LDL/HDL cholesterol ratio (4.23±0.32 vs. 2.60±0.10) were significantly higher whereas that of HDL (29.82±1.39 mg/dl vs. 40.82±6.24 mg/dl) was significantly lower in patients of CAD as compared to the controls (p<0.001). Area under receiver operating characteristic curve was >0.7 for all the markers. Higher levels of homocysteine, endothelin, and lipoprotein(a) were independently associated with increased risk of CAD. Thus, they may be helpful in risk assessment in premature cardiovascular disease and in individuals where traditional risk factors are not present.Keywords: Atherosclerosis; CAD; Endothelin; Homocysteine; Lipoprotein(a)Internet Journal of Medical Update. 2013 January;8(1):17-2
