Background Bax inhibitor-1 (BI-1) is an evolutionarily conserved cytoprotective transmembrane protein that acts as a suppressor of Bax-induced apoptosis by regulation of endoplasmic reticulum stress-induced cell death. We knocked down BI-1 in the sensitive dopa...

Crabs of the genus Lybia have the remarkable habit of holding a sea anemone in each of their claws. This partnership appears to be obligate, at least on the part of the crab. The present study focuses on Lybia leptochelis from the Red Sea holding anemones of the...

Based on sequence data from the nuclear ITS and four cpDNA regions (matK, trnH-psbA, trnL-trnF, rbcL), phylogeny of the tribe Thermopsideae was inferred. Our analyses supported this tribe being merged into a monophyletic Sophoreae in a broad sense, with exclusion...

The human male specific Y-chromosome passes from father to son essentially unchanged, but occasionally a random change, known as a mutation, occurs. These mutations, also called markers, serve as beacons and can be mapped. When geneticists identify a mutation in...
