Genome-wide dissection of AT-hook motif nuclear-localized gene family and their expression profiling for drought and salt stress in rice ().

AT-hook motif nuclear localized () genes are functionally very less explored, but their nature is very diverse. In the present study, we identified 20 genes in rice. Phylogenetic analyses and evolutionary classification of genes showed that they are conserved in plants, but the number of genes is still expanding in different crops and regulating new biological functions.

First-Ever Ischemic Stroke In Covid-19: How Is It Different? - A Stroke Registry-Based Study From South India.

Stroke associated with COVID-19 has been characterised in several multicentre retrospective studies and meta-analyses. However, they did not distinguish first-ever ischemic strokes (F-AIS). Therefore, we aimed to study the incidence, clinical characteristics, and outcomes of a cohort of F-AIS associated with COVID-19 during the first wave of the pandemic and compare this cohort with those of F-AIS without COVID-19, COVID-19 without stroke.

Drought stress in maize: stress perception to molecular response and strategies for its improvement.

Given the future demand for food crops, increasing crop productivity in drought-prone rainfed areas has become essential. Drought-tolerant varieties are warranted to solve this problem in major crops, with drought tolerance as a high-priority trait for future research. Maize is one such crop affected by drought stress, which limits production, resulting in substantial economic losses.

Influence of Gas-Flow Conditions on the Evolution of Thermally Insulating SiN Nano-Felts.

This paper discusses the role of nitrogen (N) gas flow conditions on the formation of silicon nitride (SiN) nano-felts from polysiloxane-impregnated polyurethane (PU) foams. The polymeric foam was converted into an amorphous silicon oxycarbide (SiOC) artefact during pyrolysis, which was then transformed, at a higher temperature, into a SiN felt through a reaction between the decomposition products of SiOC with N. The study identified that a N flux of ~2.

Temporal association between SARS-CoV-2 and new-onset myasthenia gravis: is it causal or coincidental?

Several case reports of COVID-19 in patients with myasthenia gravis (MG) have been documented. However, new-onset autoimmune MG following COVID-19 has been reported very rarely. We report one such case here.

Finite element submodeling technique to analyze the contact pressure and wear of hard bearing couples in hip prosthesis.

Finite element (FE) simulation plays a major role in computing stress and predicting the failure of biomedical components. Normally in past, researchers focused on developing a global computational model from the scanned data of patients to analyze the stresses and deformations. To compute the wear of the hip prosthesis, mostly the global model (GM) is used to predict the expected life for million cycles using nodal updating technique which leads to high computational effort and time.

Appendicocalicostomy: A case of mistaken identity.

Anatomical structures with similar appearance may at times be confused for each other. This situation can be compounded by lack of normal anatomical planes. We did ureterocalicostomy on a 32-year-female with secondary pelvi-ureteral junction obstruction.

Johanson-Blizzard syndrome: dental findings and management.

Aim: Oral rehabilitation of a child with Johanson-Blizzard syndrome (JBS).

Background: JBS is an extremely rare inherited disorder characterized by unusually small nose that appears 'beak shaped' due to the absence (aplasia) or underdevelopment (hypoplasia) of the nostrils (nasal alae), abnormally small, malformed primary (deciduous) teeth and misshapen or absent secondary (permanent) teeth, hearing disorder, hypothyroidism, dwarfism, malabsorption and mental retardation. It is sometimes described as a form of ectodermal dysplasia.

Effect of casein phosphopeptide-amorphous calcium phosphate containing chewing gum on salivary concentration of calcium and phosphorus: an in-vivo study.

Aim: Caries clinical trials of sugar-free chewing gum have shown that the gum is noncariogenic and in fact has anticariogenic effect through the stimulation of saliva. Sugar-free gums, therefore, may be an excellent delivery vehicle for safe and effective additive, capable of promoting enamel remineralization. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) nanocomplexes incorporated into sugar-free chewing gum have shown to remineralize enamel subsurface lesions in situ.

Association of genetic variants of mannan-binding (MBL) lectin-2 gene, MBL levels and function in ulcerative colitis and Crohn's disease.

Ulcerative colitis and Crohn's disease are the two major forms of inflammatory bowel disease (IBD). A series of reports have hypothesized interplay of genetic and environmental factors in the pathogenesis of IBD. Polymorphism in the mannan-binding lectin-2 (MBL-2) gene is known to affect the structural assembly and function thereby predisposing subjects to various diseases.

Quantitative structure activity relationship and pharmacophore studies of adenosine receptor A2B inhibitors.

Adenosine receptor A2B (ADoR A2B) is an important G protein-coupled receptor (GPCR) of the rhodopsin family, and plays a pivotal role in gastrointestinal, neurological and hypersensitive disorders. QSAR and pharmacophore studies were carried out using 63 ADoR A2B inhibitor molecules to characterize molecular features and structural requirements for biological interaction. QSAR modelling using genetic algorithm- partial least squares (G/PLS) method identified molecular shape, size electrophilicity and conformational flexibility as important descriptors for these compounds affinity to the receptor.
