Analysis of Variations in Conserved Motifs of Cag A protein in Different Helicobacter Pylori Strains

Abstract Infection with strains of Helicobacter pylori that carry the cytotoxin-associated antigen a (cagA) gene is associated with gastric carcinoma. Recent studies have shed light on the mechanism through which the cagA gene product, CagA, elicits pathophysiological actions. Helicobacter pylori infection has an association with histological gastritis, gastric atrophy, gastric cancer, and mucosa-associated lymphoid tissue […]

Comparative estimation of Penicillin production by wild and UV irradiated mutant strains of Penicillium chrysogenum

Abstract Penicillin is one of the well known antibiotics that are produced by Penicillium species of Fungi. Due to the immense applicability of penicillin antibiotic in the field of medicine it has gained a very vital position in the industrial sector. It is used to treat several bacterial infections due to its innate antibacterial activity. […]

Removal of Direct Red Dye Using Neem Leaf Litter

Abstract The adsorption of Congo red (CR) onto carbon prepared from Neem leaf litter (NLLC) and Raw Neem Leaf Litter (RNLL) was investigated. The CR adsorption increased with an increase in pH of the CR solution in high acidic region and then decreased for NLLC, and for RNLL it slightly increased but rapidly decreased in […]

A Comparative Study on the Yield of DNA Extracted from Fresh & Condition Exposed Human Scalp Hair Samples

Abstract DNA profiling is a highly conclusive, informative procedure in identification of biological specimens. In the current study, Quantification of DNA was done to detect the concentration of DNA in the samples. Quantity of DNA was calculated by taking the absorbance of samples at 260 nm by Spectrophotometer. In total 100 samples of human scalp […]
