The CD1 family of Ag-presenting molecules is able to display lipids to T cells by binding them within a hydrophobic groove connected to the protein surface. In particular, the CD1b isotype is capable of binding ligands with greatly varying alkyl chain lengths through a complex network of interconnected hydrophobic pockets. Interestingly, mycobacterial lipids such as glucose monomycolate exclusi...

Inertness and the indiscriminate use of synthetic polymers leading to increased land and water pollution are of great concern. Plastic is the most useful synthetic polymer, employed in wide range of applications viz. the packaging industries, agriculture, household practices, etc. Unpredicted use of synthetic polymers is leading towards the accumulation of increased solid waste in the natural e...

Little is known about metabolic activity of bacteria, when viscosity of their environment changes. In this work, bacterial metabolic activity in media with viscosity ranging from 0.8 to 29.4 mPas was studied. Viscosities up to 2.4 mPas did not affect metabolic activity of Vibrio ruber. On the other hand, at 29.4 mPas respiration rate and total dehydrogenase activity increased 8 and 4-fold, resp...

Dear editor,I read with interest article that published entitled *Isolation and identification of bioactive compound producing Rhodococcus spp. isolated from soil samples {IJMCM/5(1) (2015) 463-468}* [1]. Some of the genus such as Nocardia, Gordonia, Mycobacterium and Rhodococcus are in actinomycete family and they are Gram-positive and partially acid-fast. Rhodococcus species usually stain Gra...

Open-domain human-computer conversation has been attracting increasing attention over the past few years. However, there does not exist a standard automatic evaluation metric for open-domain dialog systems; researchers usually resort to human annotation for model evaluation, which is timeand labor-intensive. In this paper, we propose RUBER, a Referenced metric and Unreferenced metric Blended Ev...

A methanol-utilizing bacterium, Protaminobacter ruber, required cobalt ion or vitamin B12 as its growth factor, which could be replaced by succinate among various additions to the cobalt-deficient medium. The presence of adenosylcobalamin (adenosyl-B12)-dependent methylmalonyl-coenzyme A (CoA) mutase was demonstrated in the cell-free extracts of P. ruber. The specific activity of this mutase wa...
