The interaction of platinum with water plays a key role in (electro)catalysis. Herein, we describe a combined theoretical and experimental study that resolves the preferred adsorption structure of water wetting the Pt(111)-step type with adjacent (111) terraces. Double stranded lines wet the step edge forming water tetragons with dissimilar hydrogen bonds within and between the lines. Our results qualitatively explain experimental observations of water desorption and impact our thinking of solvation at the Pt electrochemical interface.

Background: Deoxyribonuclease 2 (DNase II) is pivotal in the clearance of cytoplasmic double stranded DNA (dsDNA). Its deficiency incurs DNA accumulation in cytoplasm, which is a hallmark of multiple neurodegenerative diseases. Our previous study showed that neuronal DNase II deficiency drove tau hyperphosphorylation and neurodegeneration (Li et al.

The temporal dynamics of bacterial and fungal communities significantly impact the manure composting process, yet viral communities are often underexplored. Bulk metagenomes, viromes, metatranscriptomes, and metabolomes were integrated to investigate dynamics of double-stranded DNA (dsDNA) virus and virus-host interactions throughout a 63-day composting process. A total of 473 viral operational taxonomic units (vOTUs), predominantly Caudoviricetes, showed distinct phase-dependent differentiation.

R-spondin1 (Rspo1) is a member of the secreted furin-like domain-containing protein family, and it is recognized for its significance in mammalian ovarian development. However, its role in teleost ovarian development remains largely uninvestigated. The Qi River crucian carp (Carassius auratus) is a species capable of gynogenesis, and it encounters challenges of premature ovarian maturation in aquaculture settings.

Enterococcus species, natural inhabitants of the human gut, have become major causes of life-threatening bloodstream infections (BSIs) and the third most frequent cause of hospital-acquired bacteremia. The rise of high-level gentamicin resistance (HLGR) in enterococcal isolates complicates treatment and revives bacteriophage therapy. This study isolated and identified forty E.

DNA gyrase is a bacterial type IIA topoisomerase that can create temporary double-stranded DNA breaks to regulate DNA topology and an archetypical target of antibiotics. The widely used quinolone class of drugs use a water-metal ion bridge in interacting with the GyrA subunit of DNA gyrase. Zoliflodacin sits in the same pocket as quinolones but interacts with the GyrB subunit and also stabilizes lethal double-stranded DNA breaks.
