Prostaglandins Differentially Regulate the Constitutive and Mechanosensitive Release of Soluble Nucleotidases in the Urinary Bladder Mucosa.

The urothelium and lamina propria (LP) contribute to sensations of bladder fullness by releasing multiple mediators, including prostaglandins (PGs) and adenosine 5'-triphosphate (ATP), that activate or modulate functions of cells throughout the bladder wall. Mediators that are simultaneously released in response to bladder distention likely influence each other's mechanisms of release and action. This study investigated whether PGs could alter the extracellular hydrolysis of ATP by soluble nucleotidases (s-NTDs) released in the LP of nondistended or distended bladders.

Microbes have been shown to adapt to stressful or even lethal conditions through displaying genome plasticity. However, how bacteria utilize the ability of genomic plasticity to deal with high antimony (Sb) stress has remained unclear. In this study, the spontaneous mutant strain SMAs-55 of sp.

Mismatch repair (MMR) is a highly conserved DNA repair pathway that recognizes mispairs that occur spontaneously during DNA replication and coordinates their repair. In Saccharomyces cerevisiae, Msh2-Msh3 and Msh2-Msh6 initiate MMR by recognizing and binding insertion deletion loops (in/dels) up to ∼ 17 nucleotides (nt.) and base-base mispairs, respectively; the two complexes have overlapping specificity for small (1-2 nt.

Taurine, although not a coding amino acid, is the most common free amino acid in the body. Taurine has multiple and complex functions in protecting mitochondria against oxidative-nitrosative stress. In this comprehensive review paper, we introduce a novel potential role for taurine in protecting from deuterium (heavy hydrogen) toxicity.

Bacterial denitrification is a main pathway for soil NO sinks, which is crucial for assessing and controlling NO emissions. Biobased polyhydroxyalkanoate (PHA) microplastic particles (MPs) degrade slowly in conventional environments, remaining inert for extended periods. However, the impacts of PHA microplastic aging on the bacterial NO sink capacity before degradation remain poorly understood.
