Earlier phylogenetic studies based on the inferred DNA sequences of the polC, rpoB and gyrA genes suggested that strains of the species Bacillus subtilis formed two clusters, indicating the presence two closely related taxa; one contained the laboratory strain 168 and the other the laboratory strain W23. Significant sexual isolation was found between strain 168 and members of the group containi...

When mixtures of cell lines 168 and 4T07, both derived from the same mouse mammary tumor, were injected into syngeneic mice, the resulting tumors, analyzed over a large size range by colony-forming assays in selective media, consisted primarily of line 4T07, even when the ratio injected was 100:1 or greater in favor of line 168. This result indicated a suppression of growth of line 168, since t...

Background: Maintenance hemodialysis has been the commonest Renal Replacement Therapy (RRT) in Myanmar. The equity is questionable Myanmar, a developing country, as developed countries reported inequities of dialysis various aspects. Methods: A cross-sectional descriptive study was conducted selected Hemodialysis Centers (HDC) which are under care government Myanmar August 2022. Data were colle...

Bacillus subtilis is both a model organism for basic research and an industrial workhorse, yet there are major gaps in our understanding of the genomic heritage and provenance of many widely used strains. We analyzed 17 legacy strains dating to the early years of B. subtilis genetics. For three--NCIB 3610T, PY79, and SMY--we performed comparative genome sequencing. For the remainder, we used co...

The small heat shock protein, -crystallin, plays a key role in maintaining lens transparency by chaperoning structurally compromised proteins. This is of particular importance in the human lens, where proteins are exposed to post-translational modifications over the lifetime of an individual. Here, we examine the structural and functional consequences of one particular modification of A-crystal...
