Distribution and abundance of fleas and rodents of plague importance in the erstwhile endemic states and international seaports of India.

Rodents are the reservoirs of the plague bacterium Yersinia pestis, which is transmitted through the bites of infected fleas. In this paper, we studied the distribution and abundance of fleas and rodents in the erstwhile endemic states and seaports of India from 2009 to 2019. The analysis showed that the Rattus rattus (Rr) was the major rodent species found in both Western (66.

A comprehensive review on glucokinase activators: Promising agents for the treatment of Type 2 diabetes.

Glucokinase is a key enzyme which converts glucose into glucose-6-phosphate in the liver and pancreatic cells of the human. In the liver, glucokinase promotes the synthesis of glycogen, and in the pancreas, it helps in glucose-sensitive insulin release. It serves as a "glucose sensor" and thereby plays an important role in the regulation of glucose homeostasis.

A knowledge-driven protocol for prediction of proteins of interest with an emphasis on biosynthetic pathways.

This protocol describes a stepwise process to identify proteins of interest from a query proteome derived from NGS data. We implemented this protocol on transcriptome to identify proteins involved in secondary metabolite and vitamin biosynthesis and ion transport. This knowledge-driven protocol identifies proteins using an integrated approach involving sensitive sequence search and evolutionary relationships.

The aim of this study was to assess the effectiveness of DHEA supplementation on IVF outcomes among poor responders undergoing IVF.

Unity and diversity among viral kinases.

Viral kinases are known to undergo autophosphorylation and also phosphorylate viral and host substrates. Viral kinases have been implicated in various diseases and are also known to acquire host kinases for mimicking cellular functions and exhibit virulence. Although substantial analyses have been reported in the literature on diversity of viral kinases, there is a gap in the understanding of sequence and structural similarity among kinases from different classes of viruses.

In vitro protective effects of botryosphaeran, a (1→3;1→6)-β-d-glucan, against mutagens in normal and tumor rodent cells.

Botryosphaeran (BOT) is an exocellular β-d-glucan (carbohydrate biopolymer) of the (1→3;1→6)-linked type produced by Botryosphaeria rhodina MAMB-05. The cytotoxic, mutagenic, genotoxic, and protective effects of this substance were evaluated in Chinese hamster lung fibroblasts (V79) and rat hepatocarcinoma cells (HTC) by the micronucleus test (MN) and the comet assay. BOT was not genotoxic in either cell line; it decreased the clastogenic effects of doxorubicin, HO, and benzo[a]pyrene.

Effect of pentacyclic triterpenes on oxalate-induced changes in rat erythrocytes.

Investigations were carried out to evaluate the effect of two, structurally related, triterpenes-betulin and lupeol-on the membrane peroxidation and antioxidant systems in red blood cells, during pyridoxine-deficient condition in rats. Increased lipid peroxidation levels in the absence and presence of ferrous sulphate, an inducer of lipid peroxidation, indicated peroxidative damage to the red-cell membrane. Na(+), K(+)-ATPase activity was decreased while that of other ion-specific ATPases were increased in the red cells of pyridoxine-deficient rats.

Protective effect of triterpenes on calcium oxalate crystal-induced peroxidative changes in experimental urolithiasis.

Naturally occurring pentacyclic triterpenes of plant origin have been identified as possessing a wide range of pharmacological effects. Lupeol (Lupa-21,20(29) dien, 3beta-ol) has been found to be efficient in reducing the risk of stone formation in animals by way of preventing crystal-induced tissue damage and dilution of urinary stone-forming constituents. In the present study, two structurally related triterpenes, lupeol and betulin (Lupa-20(29)ene-3,28 diol) were assessed for their antilithiatic effect.
