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).

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
Effect of packaging materials and storage on quality attributes of freeze dried pineapple lassi powder for defence applications
No full textThe study evaluates the effect of two different packaging materials on storage stabililty of and instant fruit-dairy functional beverage mix. Freeze dried Pineapple lassi (PL) powder was packaged in Aluminium Laminated Polyethylene (ALP) and Metallised Polyester (MP). Quality changes at elevated temperature conditions (38±1°C, 33 % relative humidity) were evaluated. Shelf life was calculated to be 44 and 62 days in MP and ALP pouches, respectively. Moisture, water activity, Vitamin C, Lactococci, TBA, colour change and Browning Index were studied in both packaging materials. ALP was found to be better than MP as samples kept in ALP preserved most of the antioxidant properties. The kinetics of Vitamin C degradation was of first order (K=-0.017 , R2= 0.99). Moisture content increased and lactococci count decreased during storag

Epigenetic modulation of macrophage polarization- perspectives in diabetic wounds
No full textDiabetes is a chronic metabolic disorder that poses a global burden to healthcare. Increasing incidence of diabetes-related complications in the affected population includes a delay in wound healing that often results in non-traumatic limb amputations. Owing to the intricacies of the healing process and crosstalk between the multitude of participating cells, the identification of hyperglycaemia-induced changes at both cellular and molecular levels poses a challenge. Macrophages are one of the key participants in wound healing and continue to exert functional changes at the wound site since the time of injury. In the present review, we discuss the role of these cells and their aberrant functions in diabetic wounds. We have extensively studied the process of macrophage polarization (MP) and its modulation through epigenetic modifications. Data from both pre-clinical and clinical studies on diabetes have co-related hyperglycaemia induced changes in gene expression to an increased incidence of diabetic complications. Hyperglycaemia and oxidative stress, create an environment prone to changes in the epigenetic code, that is manifested as an altered inflammatory gene expression. Here, we have attempted to understand the different epigenetic modulations that possibly contribute towards dysregulated MP, resulting in delayed wound healing.No Full Tex

Indigenization process of alcoholism treatment from the American to the Indian context
No full textThe education given to social work students in developing countries has been the subject of much recent study. In the earlier half of this century, professional social work was transferred from the developed world to developing countries. Much of this technology transfer was based on the belief that social work had a universally relevant methodology and an international professional identity. The consequences of this transfer are many. It has caused conflict and confusion in issues of social work practice in countries like India, Taiwan, China, and the Philippines, to name a few. In response to these conflicts social work educators have argued for the need to take into account the indigenous elements of the social, cultural, economic, and political aspects of the country for relevant social work education and training."This piece of research examines the process of indigenization of an American model of alcoholism treatment to the socio-cultural context of an Indian setting. By analyzing the history of technology transfer in India and the cultural issues which influence the lives of the people, the researcher looks at the goodness-of-fit between Western knowledge and Indian social work practice. Through focus groups and interviews with social workers in India and the United States the researcher tries to capture the process by which social work becomes ""home-made"" in India. This project reiterates the need to indigenize social work knowledge, and also emphasizes that it is essential to tap into practitioners' practice wisdom for knowledge building in social work."Made available in DSpace on 2011-05-07T14:10:31Z (GMT).

Enhanced User-driven Ranking System with Splay Tree
No full textE-learning is one of the information and communication technology products used for teaching and learning process [35]. An efficient and effective way to construct trust relationship among peer users in e-learning environment is ranking. User-driven ranking systems are based only on the feedback or rating provided by the users. In [46-48] the authors provide a variety of trust and reputation methods. Certified Belief in Strength (CBS) [45] is a novel trust measurement method based on reputation and strength . In [38] author presents a recommendation system based on the relevant feedback review to predict the user's interests, that are ranked based on the recommendations history they provide previously. Users with higher rating obtain high reputation compared to less scored users. In question answering websites like StackOverflow, new or low scored users are ignored by the community. This discourage them and their involvement with the community reduces further down, as power law states, alleged low users are pu shed to the bottom of the ranking list. Avoid this condition by encouraging less reputed users and prevent them from moving further down in ranking level. Thus, low reputed users are provided with few more chances to participate actively in the e-learning environments. A splay tree is a Binary Search Tree with self-balancing skill. The splay tree brings the recently accessed item to the top of the tree, thus active users are always on the top of the tree. A splay tree is used to represent user's ranks, and to semi-splay low ranked users again in the tree thus preventing them from further drowning in the ranking list. The focus of this research work is to find and enhance low reputed users in reputation system by providing few more chances to take part actively in the e-learning environment using the splay tree. Normalized discounted cumulative gain (NDCG) acts as a decision part for identifying drowning users
