12/15-Lipooxygenase Inhibition Reduces Microvessel Constriction and Microthrombi after Subarachnoid Hemorrhage in Mice.

Background And Purpose: Impaired cerebral circulation, induced by blood vessel constrictions and microthrombi, leads to delayed cerebral ischemia after subarachnoid hemorrhage (SAH). 12/15-Lipooxygenase (12/15-LOX) overexpression has been implicated in worsening early brain injury outcomes following SAH. However, it is unknown if 12/15-LOX is important in delayed pathophysiological events after SAH.

Ethnic variation and the relevance of homozygous RNF 213 p.R4810.K variant in the phenotype of Indian Moya moya disease.

Background And Purpose: Polymorphisms in Ring Finger Protein 213 (RNF 213) gene have been detected to confer genetic susceptibility to Moya moya disease (MMD) in the East Asian population. We investigated the frequency of RNF 213 gene polymorphism and its association with MMD phenotypes in the Indian population.

Materials And Methods: A case-control study for RNF 213 polymorphism involving 65 MMD patients, 75 parents, and 120 controls were performed.

Methylation map genes can be critical in determining the methylome of intracranial aneurysm patients.

Intracranial aneurysm is often asymptomatic until the time of rupture. Elevated homocysteine is reported in vascular diseases. Identifying early events in homocysteine metabolism through methylation map genes may prevent fatality.

Effects of bisphenol-A on male reproductive success in adult Kadaknath chicken.

Bisphenol-A (BPA) adversely affects human and animal reproductive success in many ways, but this information is scant on birds. In the present study, we investigated the reproductive toxicity of BPA in adult Kadaknath chicken using two BPA dosages orally (1 or 5 mg/kg body weight) for seven weeks. In order to assess BPA toxicity, sperm functions, fertilizing ability, serum testosterone concentration and testis histopathology were measured in treated and control chickens.

Bisphenol A reduces fertilizing ability and motility by compromising mitochondrial function of sperm.

Bisphenol A (BPA) acts as an endocrine disruptor, affects animal reproductive success in vivo and affects sperm functions in vitro at environmentally relevant concentrations, leading to reduction in sperm motility and fertilizing ability in fish. The effect of in vitro BPA on avian sperm functions has not been explored. The present study examined the effect of environmentally relevant concentrations of BPA (0 mM, 0.

Development of a new method for sperm RNA purification in the chicken.

Currently RNA transcripts are being used as male fertility biomarker for many mammalian species, but research work on chicken is at halt because classical RNA isolation methods are not effective for chicken spermatozoa. Hence, attempts have been made to optimize RNA isolation protocol from chicken sperm by using different methods, and to confirm the presence of sperm-specific transcripts of PRM and PLCZ1. Semen samples were centrifuged at low speed for removing debris like uric acid.
