Selective Homodecoupled 1D-H NMR Experiment for Unravelling Enantiomers.

H NMR spectroscopy is a quick and easy tool to resolve enantiomers. However, the paradigm of resolution of enantiomers by H NMR is a difficult task due to the minor chemical shift differences and overlap of the resonances of the enantiomers. In the current study, we have performed the conventional selective homodecoupling 1D-H NMR experiment to achieve chiral resolutions.

Modulation of obesity associated metabolic dysfunction by novel lipophilic fraction obtained from Agaricus bisporus.

Aim: The present study aimed to prepare a novel lipophilic fraction rich in fat soluble bioactive from Agaricus bisporus and investigated its impact through in vitro and in vivo assessments since the prospective biological activities of fat soluble components from mushrooms are limited.

Folate derivatives, 5-methyltetrahydrofolate and 10-formyltetrahydrofolate, protect BEAS-2B cells from high glucose-induced oxidative stress and inflammation.

Folate (vitamin B) and its biologically active derivatives are well-known antioxidant molecules protecting cells from oxidative degradation. The presence of high glucose, often found in diabetic patients, causes oxidative stress resulting in cellular stress and inflammatory injury. Cells in organs such as the lung are highly prone to inflammation, and various protective mechanisms exist to prevent the progressive disorders arising from inflammation.

Obesity-associated biochemical markers of inflammation and the role of grain phytochemicals.

The incidence of obesity or excessive fat accumulation in the body is increasing worldwide and has become one of the major growing health problems. Obese condition is linked with an increased level of body lipids, oxidative stress, and expression of inflammatory markers. This leads to plasma and hepatic hyperlipidemia, activation of proinflammatory cytokines (TNF-α, IL-6, and IL-1β), and transcriptional factors, which in turn lead to a high risk of cardiovascular diseases, insulin resistance, diabetes, asthma, rheumatological problem, and liver failure.

Modulation of gut microbiota by bioactive compounds for prevention and management of type 2 diabetes.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by hyperglycemia and insulin resistance. Gut microbiota (GM) are specific groups of microbes colonized in the gastrointestinal (GI) tract. They profoundly influence health, disease protection, and associated with metabolic activities, and play a vital role in the production of functional metabolites from dietary substances.

Rotenone mediated developmental toxicity in Drosophila melanogaster.

Rotenone (ROT) is a widely used natural pesticide, and its effect on growth and developmental toxicity remain unclear. In the present study, the effects of ROT exposure on the reproductive structure and function of the female Drosophila melanogaster and third instar larvae were investigated. ROT exposure on female Drosophila melanogaster resulted in developmental inhibition and ovarian abnormality, which were evident from the disruptive growth of border cells as well as morphological changes in the orientation of nurse cells during the 9th-10th stage of developing egg chamber of in the Drosophila ovary.

OsSalT gene cloned from rice provides evidence of its role in salinity and drought stress tolerance.

Abiotic stresses impose a huge threat to agricultural productivity and global food security. To counter this challenge, the precise identification of the right candidate gene (s) for conferring abiotic stress tolerance without compromising the growth and yield is crucial. OsSalT is identified as a salt stress responsive gene located on SalTol QTL of chromosome 1 of rice, however, there is no genetic evidence of its function and probable pathway of its regulation.

Endosulfan causes oxidative stress in the liver and brain that involves inhibition of NADH dehydrogenase and altered antioxidant enzyme status in rat.

Endosulfan, a neurotoxic, highly persistent organochlorine insecticide, is known for its acute and chronic toxicity. We have shown that a single sublethal dose of endosulfan caused high induction of oxidative stress in the liver and brain by altering the antioxidant status, as shown by reduction in the antioxidant enzymes SOD, GPx, GST, GR along with increased ROS and lipid peroxidation. The cerebral region in the brain showed a higher level of oxidative stress than the cerebellum, revealing differential sensitivity of the brain regions to endosulfan.

Comparative assessment of antioxidant and immunomodulatory properties of skimmed milk protein hydrolysates and their incorporation in beverage mix.

Background: Milk-derived protein hydrolysates have generated a great deal of interest recently due to their numerous beneficial health effects. However, there are few comparative studies on protein hydrolysates from different dairy species, their production, characterization, and bioactivity. In the present study, skimmed milk from both major and minor dairy species was hydrolyzed with alcalase, and its protein profiles were studied using tricine polyacrylamide gel electrophoresis and reverse phase-high protein liquid chromatography.

Nutritional evaluation of flour, its bread and effect of additives.

Abstract: The present research sought to experiment the effect of additives such as dry gluten powder (DGP), fungal α-amylase (FAA), sodium stearoyl-2-lactylate (SSL) and their combination (GAS) on the rheological and nutritional profile of bread. The incorporation of varied percentage (0-20%) of flour (ssF) into WF(Wheat Flour) was optimized at 15%. The results showed that the incorporation of 15% ssF decreased the farinograph dough stability and extensograph resistance to extension.

Astaxanthin ameliorates hyperglycemia induced inflammation via PI3K/Akt-NF-κB signaling in ARPE-19 cells and diabetic rat retina.

Astaxanthin has been reported to possess anti-inflammatory effect but the exact mechanism in protecting the retinal pigment epithelial (RPE) cells is not clear. Hence, we hypothesized that astaxanthin could protect RPE by inhibiting ROS-mediated inflammation. The purpose of this study is to understand the retinal protective mechanism of astaxanthin in modulating hyperglycemia (HG) induced inflammation in ARPE-19 cell and diabetic rat retina.

Effective inhibition of adipogenesis-mediated inflammation by a macular carotenoid, lutein in vitro.

An absolute interlinks between inflammation and obesity with scarce investigations on the role of lutein in inflammation-induced obesity motivated us to explore the protective mechanism of lutein on adipogenesis-mediated inflammation in vitro by culturing RAW264.7 macrophages in adipocyte conditioned medium. The RAW264 macrophage cells were cultured with adipocyte-conditioned media, and the potency of lutein on the expression of adipocyte inflammation-associated protein markers (IL-1β, MCP-1, TNF-α, IL-6, NF-κB, and IKKα/β) were analyzed by western blotting.

A machine learning-based approach to determine infection status in recipients of BBV152 (Covaxin) whole-virion inactivated SARS-CoV-2 vaccine for serological surveys.

Data science has been an invaluable part of the COVID-19 pandemic response with multiple applications, ranging from tracking viral evolution to understanding the vaccine effectiveness. Asymptomatic breakthrough infections have been a major problem in assessing vaccine effectiveness in populations globally. Serological discrimination of vaccine response from infection has so far been limited to Spike protein vaccines since whole virion vaccines generate antibodies against all the viral proteins.
