An approach to improve the existing ribbon retting of jute fibre using concrete tank and natural catalyst.

The ribbon retting method has been developed as a remedy for the issues associated with the conventional water retting method. But this method has not yet gained popularity among jute growers due to the unavailability of catalyst, inadequate training and lack of interest of farmers. The study deals with the improvement of the existing ribbon retting process by using a concrete tank with or without fermented soybean as a natural catalyst in different proportions.

Niacinamide leave-on formulation provides long-lasting protection against bacteria in vivo.

Antimicrobial peptides (AMPs) form a part of the skin's innate immune system. Their primary activity is to provide antimicrobial benefits and hence protect from infections. AMPs that are present on human skin include psoriasin (S100A7), RNase 7, lysozyme, LL-37 and defensins.

Sebum and Hydration Levels in Specific Regions of Human Face Significantly Predict the Nature and Diversity of Facial Skin Microbiome.

The skin microbiome varies across individuals. The causes of these variations are inadequately understood. We tested the hypothesis that inter-individual variation in facial skin microbiome can be significantly explained by variation in sebum and hydration levels in specific facial regions of humans.

Tumor-prone phenotype of the DDB2-deficient mice.

DDB2 is an essential subunit of the damaged-DNA recognition factor DDB, which is involved in global genomic repair in human cells. Moreover, DDB2 is mutated in the repair-deficiency disease xeroderma pigmentosum (Group E). Expression of DDB2 in human cells is induced by P53, BRCA1 and by ionizing radiation.

Involvement of in vivo induced cheY-4 gene of Vibrio cholerae in motility, early adherence to intestinal epithelial cells and regulation of virulence factors.

Using a global transcription profile approach cheY-4 of Vibrio cholerae was identified as an in vivo induced gene. In the present study, duplication of the gene in the chromosome resulted in increased motility, increased chemotactic response towards isolated intestinal mucus layer and stronger adhesion to human intestinal epithelial cell line at an early phase of infection compared to wild type and a null mutant strain. In contrast to the cheY-4 null mutant, duplication of cheY-4 gene resulted in increased expression of ctxAB and tcpA, the two major virulence genes of V.

Involvement of in vivo induced icmF gene of Vibrio cholerae in motility, adherence to epithelial cells, and conjugation frequency.

Previously, using global transcription profile approach icmF gene of Vibrio cholerae was identified as an in vivo induced gene. In the present study, the icmF gene of V. cholerae O395 was cloned, sequenced, and used to construct an icmF insertion mutant.
