Multicentric carpotarsal osteolysis syndrome (MCTO) is a rare autosomal dominant skeletal dysplasia characterised by swelling and restriction of movement in the wrist and ankle joints, as well as osteolysis of the carpal and tarsal bones, that can be misdiagnosed as juvenile idiopathic arthritis. We describe five Indian families with heterozygous nonrecurrent missense pathogenic variants in exon 1 of MAF bZIP transcription factor B (MAFB).

In this study, enterocin LD3 was purified from the cell-free supernatant of a food isolate, Enterococcus hirae LD3 using multistep chromatography. In the fruit juice, lethal concentration (LC) of enterocin LD3 was found to be 260 µg/mL against Salmonella enterica subsp.

Its endemic type is present in tropical, sub-tropical and Mediterranean areas around the world which accounts for a lot of deaths every year. Currently, a variety of techniques are available for detection of leishmaniasis each technique having it's own pros and cons.

Several online pipelines and standalone tools are available for WGS analysis of () complex (MTBC). While they facilitate the processing of WGS data with minimal user expertise, they are either too general, providing little insights into bacterium-specific issues such as gene variations, INDEL/synonymous/PE-PPE (IDP family), and drug resistance from sample data, or are limited to specific objectives, such as drug resistance.

Main protease (M) of SARS-CoV-2 plays a significant role in the viral replication, transcription and disease propagation as well as a potential candidate for drug discovery and development for COVID-19 infection. The current study employed state of art structure-based drug discovery to decipher the role of phytochemicals of against M.

Probiotics have been considered as an economical and safe alternative for the treatment of a large number of chronic diseases and improvement of human health. They are known to modulate the host immunity and protect from several infectious and non-infectious diseases. The colonization, killing of pathogens and induction of host cells are few of the important probiotic attributes which affect several functions of the host.

Cellular ubiquitination, a normal physiological process to maintain homeostasis, is emerging one such exploited mechanism. Ubiquitin (Ub), a small protein modifier, is conjugated to diverse protein substrates to regulate many functions.

Using extensive computational approaches, we shortlisted ORFs/proteins unique to among 13 different species of mycobacteria and identified a hypothetical protein Rv1509 as a 'signature protein' of . This unique protein was found to be present only in and absent in all other mycobacterial species, including BCG.

During this period, their nutritional requirements and metabolic activities are minimized due to highly restricted foraging activities. The egg-laying by queen and rearing of unsealed and sealed brood are decreased, however their extent is governed by the quantum of stored food available.

However, investigating a representative dataset of 500 human N-glycoproteins, we observed the sites of N-linked glycosylations or N-glycosites, to be predominantly present in the regions of predicted order. When compared with disordered stretches, ordered regions were not found to be enriched for asparagines, serines and threonines, residues that constitute the sequon signature for conjugation of N-glycans.

The plan of this study was to assess the level of awareness about cervical cancer and HPV vaccine among females of rural and urban areas of Haryana, India. This cross-sectional study was performed using a comprehensive self-designed questionnaire on 1500 women of urban (700) and rural (800) background aged 18-65 years, evaluating their knowledge for cervical cancer and screening, HPV infection and its preventive measure, and symptoms and risk factors.

Oxidation of ethene and benzene by chromium oxide (CrO) supported on silica (SiO) was investigated by employing hybrid quantum mechanics/molecular mechanics (QM/MM) model calculations. Various mechanistic possibilities, such as C-H or C=C bond activation of hydrocarbons, were investigated in detail for the reaction of ethene and benzene with CrO grafted on a silica surface. While activation of the C-H bond leads to the formation of alcohol, epoxide is obtained via C=C bond activation.

The order of binding energy for (ZnO)-nucleotide hybrid systems is observed to be (ZnO) + nuc-C ˃ (ZnO) + nuc-A ˃ (ZnO) + nuc-G ˃ (ZnO) + nuc-T. The binding of nucleotide units with the cluster has been explained on the basis of molecular electrostatic potential (MEP) plots, hydrogen bonding, glycosidic torsion angles, density of state (DOS) plots.

Molecular dynamics (MD) is a computational technique which is used to study biomolecules in virtual environment. Each of the constituent atoms represents a particle and hence the biomolecule embodies a multi-particle mechanical system analyzed within a simulation box during MD analysis. The potential energies of the atoms are explained by a mathematical expression consisting of different forces and space parameters.
