Improved Arterial Stiffness Indices 3 and 6 Months after Living-donor Renal Transplantation.

Arterial stiffness is a non-traditional risk factor of cardiovascular disease and may explain part of the excess cardiovascular risk in chronic kidney disease patients. Successful renal transplantation (RT) may restore renal function and improve several metabolic abnormalities involved in arterial stiffness. This prospective study conducted non-invasive assessments of arterial stiffness indices [the augmentation index (AI) and pulse wave velocity (PWV)] in end-stage kidney disease (ESKD) patients before RT and 3 and 6 months after living-donor RT, alongside the effects of age and calcineurin inhibitors on arterial stiffness.

Chronic hepatitis B and occult infection in chemotherapy patients - evaluation in oncology and hemato-oncology settings: The CHOICE study.

Background: Reactivation of hepatitis B virus (HBV) infection is a well-known risk that can occur spontaneously or following immunosuppressive therapies, including cancer chemotherapy. HBV reactivation can cause significant morbidity and even mortality, which are preventable if at-risk individuals are identified through screening and started on antiviral prophylaxis.

Aim: To determine the prevalence of chronic HBV (CHB) and occult HBV infection (OBI) among oncology and hematology-oncology patients undergoing chemotherapy.

"Gearing" up for dynamin-catalyzed membrane fission.

Endocytic dynamins self-assemble into helical scaffolds and utilize energy from GTP hydrolysis to constrict and sever tubular membranous necks of budded endocytic intermediates. They bind the membrane using a pleckstrin-homology domain (PHD). The PHD is characterized by four unstructured loops, two of which partially insert into the membrane.

Whole Exome Sequencing Reveals Novel Variants in Unexplained Erythrocytosis.

Erythrocytosis is characterized by an increase in red cells in peripheral blood. Polycythemia vera, the commonest primary erythrocytosis, results from pathogenic variants in in ∼98% of cases. Although some variants have been reported in -negative polycythemia, the causal genetic variants remain unidentified in ∼80% of cases.

Mechanistic analysis of a novel membrane-interacting variable loop in the pleckstrin-homology domain critical for dynamin function.

Classical dynamins are best understood for their ability to generate vesicles by membrane fission. During clathrin-mediated endocytosis (CME), dynamin is recruited to the membrane through multivalent protein and lipid interactions between its proline-rich domain (PRD) with SRC Homology 3 (SH3) domains in endocytic proteins and its pleckstrin-homology domain (PHD) with membrane lipids. Variable loops (VL) in the PHD bind lipids and partially insert into the membrane thereby anchoring the PHD to the membrane.

Taxonomic and genomic characterization of Sporosarcina cyprini sp. nov., moderately tolerant of Cr and Cd isolated from the gut of invasive fish Cyprinus carpio var. communis (Linn., 1758).

A Gram-stain-positive, motile, and rod-shaped bacterium, designated as strain MB25, was isolated from the gut of Cyprinus carpio from the highly polluted river Yamuna, India. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain MB25 belonged to the genus Sporosarcina, sharing the highest sequence similarity with S. luteola Y1 (98.

Prolonged fever and pancytopenia in a case of severe dengue may be secondary hemophagocytic lymphohistiocytosis.

The diagnosis of secondary hemophagocytic lymphohistiocytosis (HLH) in the setting of dengue fever is usually challenging but should be kept in mind in patients with persistent fever, pancytopenia, and multiorgan dysfunction. We report a case of severe dengue who had prolonged fever with multiorgan involvement, laboratory features fulfilling the diagnostic criteria of HLH, and had a prompt response with high-dose corticosteroids. Physicians should be aware of this rare clinical syndrome and its variable clinical presentations so that fatal outcomes can be prevented with prompt and appropriate treatment.

Methods And Materials: In this descriptive study, we analyzed all patients who were COVID-19 positive during the scheduled radiotherapy course, those who had an infection while on neoadjuvant treatment period, or during surgery before the start of radiation. The study period was from June 2020 to May 2021.

Metagenomic insights to understand the role of polluted river Yamuna in shaping the gut microbial communities of two invasive fish species.

The gastrointestinal microbial community plays a crucial role in host health, immunity, protection, development and provides nutrients to the host. The rising human-induced pollution and heavy metal contamination in all aquatic systems globally has led us to explore the gut microbial diversity of two exotic invasive fish Cyprinus carpio (Linnaeus, 1858) and Oreochromis niloticus (Linnaeus,1857) from river Yamuna, India. These fishes are aquatic bioindicators with high demographic resilience.

Protein-Protein Interactions on Membrane Surfaces Analysed Using Pull-Downs with Supported Bilayers on Silica Beads.

Discovery-based proteomics workflows that identify novel interactors rely on immunoprecipitations or pull-downs with genetically tagged bait proteins immobilized on appropriate matrices. But strategies to analyse protein interactions on a diffusible-membrane surface combined with the practical ease of pull-downs remain unavailable. Such strategies are important to analyse protein complexes that mature in composition and stability because of diffusion-based encounter between participant proteins.
