Adaptation of a methanogen to Fe corrosion via direct contact.

Due to unique genomic adaptations, Methanococcus maripaludis Mic1c10 is highly corrosive when in direct contact with Fe. A critical adaptation involves increased glycosylation of an extracellular [NiFe]-hydrogenase, facilitating its anchoring to cell surface proteins. Corrosive strains adapt to the constructed environment via horizontal gene transfer while retaining ancestral genes important for intraspecies competition and surface attachment.

Impact of Treatment with Direct Antivirals on Coagulation Parameters in Patients with Hepatitis C Virus-Related Liver Cirrhosis and Sustained Virological Response.

: Sustained virologic responses (SVRs) lead to a decrease in portal hypertension, the regression of fibrosis, and the improvement in the hepatic synthesis of procoagulant and anticoagulant factors. We aimed to assess the influence of SVR on coagulation parameters in cirrhotic patients with HCV treated with DAAs. : We performed a prospective study in the Institute of Gastroenterology and Hepatology Iasi, Romania, between January 2022 and February 2024.

Using cluster analysis to explore COVID-19 vaccine booster hesitancy by levels of medical mistrust in fully vaccinated US adults.

Background: Underlying causes of vaccine hesitancy could significantly affect successful uptake of the SARS-CoV2 vaccine booster doses during new waves of COVID-19. Booster rates among US adults are far below what is needed for immunity, but little is known about booster hesitancy among fully vaccinated adults and whether medical mistrust exacerbates barriers to uptake.

Methods: A cross-sectional survey was completed among 119 adults in Philadelphia, PA who reported having received the primary SARS-CoV2 vaccine series but not a booster dose.

Diagnosis and treatment challenges in a rare infection: A case report.

The genus includes >180 species of Gram-positive, anaerobic, sporulating bacteria. Under certain conditions, these can cause a wide range of invasive infections in humans. occurs in the commensal intestinal flora and related bacteremia typically occurs secondary to an injury to the intestinal mucosa and in the presence of predisposing conditions, such as gastrointestinal disorders, malignancies, diabetes, HIV infection or neutropenia.

Combining electron transfer, spin crossover, and redox properties in metal-organic frameworks.

Hofmann coordination polymers (CPs) that couple the well-studied spin transition of the Fe central ion with electron-responsive ligands provide an innovative strategy toward multifunctional metal-organic frameworks (MOFs). Here, we developed a 2D planar network consisting of metal-cyanide-metal sheets in an unusual coordination mode, brought about by infinitely π-stacked redox-active bipyridinium derivatives as axial ligands. The obtained family of materials show vivid thermochromism attributed to electron transfer and/or electronic spin state change processes that can occur either independently or concomitantly.
