Role of microRNA, bta-miR-375 in Immune Sturdiness of Vechur: The Native Cattle Breed of Kerala, India.

In the present study, next generation sequencing was employed to identify and explore the differential expression profiles of microRNAs (miRNAs) in peripheral blood mononuclear cells (PBMCs) of crossbred ( x ) and Vechur () cattle in response to the bacterial endotoxin-lipopolysaccharide (LPS). The PBMCs from adult apparently healthy female crossbred cows and Vechur cattle, a native cattle breed of Kerala, India were stimulated with 10 μg/mL of LPS for 6 h. Among the differentially expressed miRNAs, the expression of 13 miRNAs showed statistically significant up regulation while, significant decrease in the expression of 15 miRNAs was noticed in LPS treated PBMCs of Vechur cattle compared to crossbred cows.

Molecular characterisation of coding regions of gene in Vechur cattle by cDNA sequencing.

Hypoxia-inducible factor (HIF)-1α is a transcription factor stabilized by hypoxia by inducing or suppressing the homeostatic regulatory gene expression, enabling tissues and cells to survive despite fluctuations in environmental circumstances. As the name implies, hypoxia-inducible factor-1 is secreted not only as a cellular response to hypoxia but also in heat stress and oxidative stress. The goal of this work was to determine the molecular characterisation of the gene coding region as well as the differences in HIF-1αprotein primary structure between Vechur cattle and other cattle breeds in the online databases.

Molecular characterization of human isolates from Kerala.

Background & Objectives: Human dirofilariosis is a well-recognized zoonosis caused by several species of the genus Dirofilaria. The disease is prevalent among canines and human beings in Kerala. The objective of the present study was to confirm the human Dirofilaria isolates by molecular characterization.

Characterization of promoter sequence of toll-like receptor genes in Vechur cattle.

Aim: To analyze the promoter sequence of toll-like receptor (TLR) genes in Vechur cattle, an indigenous breed of Kerala with the sequence of Bos taurus and access the differences that could be attributed to innate immune responses against bovine mastitis.

Materials And Methods: Blood samples were collected from Jugular vein of Vechur cattle, maintained at Vechur cattle conservation center of Kerala Veterinary and Animal Sciences University, using an acid-citrate-dextrose anticoagulant. The genomic DNA was extracted, and polymerase chain reaction was carried out to amplify the promoter region of TLRs.

Immunomodulatory and antitumour properties of Psoralea corylifolia seeds.

Psoralea corylifolia seed extract has been found to stimulate the immune system in mice. Administration of the extract was found to inhibit EAC ascitic tumour growth and stimulate natural killer cell activity, antibody-dependent cellular cytotoxicity, antibody-forming cells and the antibody complement-mediated cytotoxicity during tumour development.

Defective interleukin-2 R gene expression in gastric carcinoma patients.

Peripheral blood T lymphocytes from 15 patients with gastric carcinoma and 6 normal healthy controls were evaluated for Interleukin-2 R gene expression. Total RNA was extracted from T cell-enriched fractions of patients as well as from control peripheral blood lymphocytes, with or without mitogenic stimulation. The presence of mRNA for IL-2 R alpha evaluated by Northern blot analysis revealed that unstimulated T cells expressed lower levels of IL-2 R mRNA than PHA stimulated T cells.

Primary structures of concanavalin A-like lectins from seeds of two species of Canavalia.

The amino acid sequences of two lectins from the seeds of Canavalia lineata and C. virosa have been determined by the manual Edman degradation method. Both proteins were found to be highly homologous to concanavalin A, a lectin from C.

Antipoisonous property of canavalia virosa.

Canavalia virosa seed is applied on the wound after removing the seed coat. This sticks to the skin till the poison is completely removed and falls off which takes five to seven hours. There is complete relief of the poisoning in the case of Scorpion, Centipede.
