Exploring the Inhibition of α-Carbonic Anhydrase by Sulfonamides: Insights into Potential Drug Targeting.

, the causative agent of toxoplasmosis, is a protozoan parasite capable of infecting a wide range of hosts, posing significant health risks, particularly to immunocompromised individuals and congenital transmission. Current therapeutic options primarily target the active tachyzoite stage but are limited by issues such as toxicity and incomplete efficacy. As a result, there is an urgent need for alternative therapies that can selectively target parasite-specific mechanisms critical for metabolic processes and host-parasite interactions.

Impaired insight in schizophrenia is associated with higher frontoparietal cerebral blood flow: an arterial spin labeling study.

Impaired insight into illness occurs in up to 98% of patients with schizophrenia, depending on the stage of illness, and leads to negative clinical outcomes. Previous neuroimaging studies suggest that impaired insight in patients with schizophrenia may be related to structural and functional anomalies in frontoparietal brain regions. To date, limited studies have investigated the association between regional cerebral blood flow (CBF) and impaired insight in schizophrenia.

Exploring aliphatic sulfonamides as multiclass inhibitors of the carbonic anhydrases from the pathogen bacterium Vibrio cholerae.

This study investigates aliphatic sulfonamide derivatives as inhibitors of the α-, β-, and γ-class carbonic anhydrase (CA) isoforms from Vibrio cholerae (VchCAs). A series of 26 compounds bearing a triazole linker and urea- or ether-based tails were described and evaluated for their inhibitory action using a stopped-flow CO hydrase technique. These inhibitors demonstrated a preferential efficacy against VchCAβ.

Edge-to-edge repair for tricuspid regurgitation: 1-year follow-up and clinical implications from the TR-Interventional Study.

Aims: Tricuspid regurgitation affects 7% of the population, with moderate-to-severe tricuspid regurgitation contributing to up to 12% of heart failure-related hospitalizations. Traditional treatments have several limitations, prompting the exploration of innovative interventions. Our study aims to investigate the efficacy and clinical outcomes following transcatheter edge-to-edge repair (TEER) in patients with severe, symptomatic tricuspid regurgitation through a 1-year follow-up.

Kinetic and structural studies of gamma-carbonic anhydrase from the oral pathogen Porphyromonas gingivalis.

Porphyromonas gingivalis, a key pathogen in periodontal, plays a critical role in systemic pathologiesdiseases by evading host defence mechanisms and invading periodontal tissues. Targeting its virulence mechanisms and overcoming drug resistance are essential steps toward effective therapeutic development. In this study, we focused on the Carbonic Anhydrase (CA, EC: 4.
