Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization
The FEBS Journal, EarlyView.PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

International Endodontic Journal, EarlyView.ABSTRACT Background Dental pulp inflammation triggers immune responses involving macrophages and dental pulp stem cells (DPSCs), which interact to regulate angiogenesis essential for tissue repair. M1 pro‐inflammatory macrophages predominate early in pulpitis, and clarifying their angiogenic role is vital in identifying inflammatory regenerative ...

STUDIES ON THE TOXIN PRODUCTION OF THE SHIGA BACILLI [PDF]
Journal of Experimental Medicine, 1936 1. The S, R, and Rn variants of the Shiga bacillus are equally toxic. 2. The effect of the toxin upon rabbits is the same, whether it is derived from filtrates of broth cultures (3 to 6 days old), or is obtained by autolysis of the killed bacteria, grown on agar surface.

Multiplex PCR to Diagnose Gastrointestinal Infections: Key Limitations in Interpretation
United European Gastroenterology Journal, Volume 14, Issue 7, September 2026.ABSTRACT Multiplex polymerase chain reaction (PCR) panels are increasingly used for the evaluation of acute diarrhea, providing rapid and sensitive detection of a broad range of enteric pathogens. However, their widespread adoption has created important interpretive challenges for clinicians.

Beraprost Attenuates Starvation‐Induced Apoptosis and Protects Feline Endothelial Cells
Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.This study established a feline endothelial cell starvation model to test the anti‐apoptotic effects of beraprost and its stereoisomers. Beraprost and beraprost‐314d reduced starvation‐induced apoptosis by inhibiting caspase‐3/7 activity and modulating Bax expression, while beraprost‐315d was less potent.

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves
Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...
