Molecular docking study of tripeptides VPP and IPP inhibiting angiotensin I converting enzyme to alleviate high altitude pulmonary edema

High altitude pulmonary edema (HAPE) remains the major cause of death related to high altitude exposure with a high mortality in absence of emergency treatment. Due to the deprival of oxygen in higher altitudes, the blood vessels constricts and squeezes blood in the vessels. This makes pressure to go up which in turn forces blood into air pockets in lungs that can kill people with HAPE. Angiotensin Converting Enzyme...

Application of subspecies-specific marker system identified from Oryza sativa to Oryza glaberrima accessions and Oryza sativa × Oryza glaberrima F1 interspecific progenies

  Interspecific hybrids (F1's) between Asian rice (Oryza sativa 2n=24 AA) and African rice (Oryza glaberrima 2n=24 AA) are almost completely sterile. This hybrid sterility barrier is mainly caused by an arrest of pollen development at the microspore stage. Intersubspecific F1 hybrid sterility is mainly caused by cryptic chromosomal aberrations and allelic interaction...

Chromosome complement and C-banding patterns in 6 species of grasshoppers

Chromosomes with detailed karyotypic information (nature, number, size, relative length, length of X-chromosome, nature of X-chromosome) and C-banding patterns of six species of grasshoppers belonging to sub-families- Tryxalinae, Oedipodinae and Catantopinae are discussed. The karyotypes comprises of acrocentric chromosomes with complement number 2n=23 (male). Constitutive heterochromatin distribution was found at...

Genetic polymorphism BMP15 and GDF9 genes in Sangsari sheep of Iran

Different mutations in the bone morphogenetic protein 15 (BMP15) and the Growth Differentiation Factor 9 (GDF9) genes cause increased ovulation rate and infertility in a dosage-sensitive manner in sheep. In this study, blood samples (140 ewes and 10 rams) were initially taken from 150 Sangsari sheep breed in Damghan animal breeding Centre using venojects treated with the anti-clot substance (EDTA) and subsequently...
