Methanol transfer supports metabolic syntrophy between bacteria and archaea.

In subsurface methanogenic ecosystems, the ubiquity of methylated-compound-using archaea-methylotrophic methanogens-implies that methylated compounds have an important role in the ecology and carbon cycling of such habitats. However, the origin of these chemicals remains unclear as there are no known energy metabolisms that generate methylated compounds de novo as a major product. Here we identified an energy metabolism in the subsurface-derived thermophilic anaerobe Zhaonella formicivorans that catalyses the conversion of formate to methanol, thereby producing methanol without requiring methylated compounds as an input.

To further validate these results, a large-scale database was analyzed.
Methods: This retrospective multicenter cohort study included infants born at <28 weeks' gestational age between 2003 and 2016.
Fruiting phenology affects the direction of vertical seed dispersal by mammals and birds across mountain ranges.

Vertical seed dispersal towards higher or lower altitudes is an important process for plants' adaptation to climate change. Although many plants depend on animals for seed dispersal, studies on vertical seed dispersal by animals, determined by complex animal behaviours, are scarce. Previous studies hypothesised that animals inhabiting temperate regions disperse seeds uphill in spring/summer and downhill in autumn/winter due to their seasonal movement following the altitudinal gradients in food phenology.

Most giant viruses including Mimiviridae family build large viral factories within the host cytoplasms. These giant viruses are presumed to possess specific genes that enable the rapid and massive replication of their large double-stranded DNA genomes within viral factories. It has been revealed that a functionally uncharacterized protein, MutS7, is expressed during the operational phase of the viral factory.

BMC Oral Health
December 2024
Faculty of Pharmaceutical Sciences, Tokyo University of Science, 2641 Yamazaki, Chiba, Noda, 278-8510, Japan.
Background: With the rise in the older population, it has become important to understand the relationship between oral frailty and drug use to consider appropriate medical interventions and drug use for older persons.
Objective: To clarify the relationship among oral frailty, drug use, and other patient backgrounds and to identify relevant factors using information from patient questionnaires and pharmacy medication history records.
Methods: This cross-sectional study involved community-dwelling older adults.
