Composition, Seasonal Dynamics and Metabolic Potential of the Rhizosphere Microbiome Associated with Wild White Poplar.

The white poplar () is a dioecious woody plant with significant potential for the phytoremediation of soils. To realize this potential, it is necessary to utilize growth-promoting microorganisms. One potential source of such beneficial microorganisms is the rhizosphere community of wild-growing trees.

[ArdA Protein Specificity against Type I Restriction-Modification Systems].

The ArdA DNA-mimic antirestriction proteins inhibit type I restriction-modification (RMI) systems by binding instead of DNA to RMI. The ArdA specificity to DNA methylation sites recognized by RMI complexes remains poorly understood; i.e.

Non-Susceptibility Gene Variants in Head and Neck Paragangliomas.

Head and neck paragangliomas (HNPGLs) are rare neoplasms that, along with pheochromocytomas and extra-adrenal paragangliomas, are associated with inherited mutations in at least 12 susceptibility genes in approximately 40% of cases. However, due to the rarity of HNPGLs, only a series of small-scale studies and individual cases have reported mutations in additional genes that may be involved in tumorigenesis. Consequently, numerous disease-causing mutations and genes responsible for the pathogenesis of HNPGLs remain poorly investigated.

AcidAGE: a biological age determination neural network based on urine organic acids.

Organic acids reflect the course of all important metabolic processes and the effects of diet, nutrient deficiency, lifestyle, and microbiota composition. In present work, we focused on identifying age-related changes in organic acids in urine, and creating a neural network model based on them to determine biological age. The investigation involves data on concentrations of 60 organic acids in urine of 863 samples.

is associated with normal muscle mass and is related with sarcopenia in cirrhosis.

Background: Sarcopenia and gut dysbiosis are common in cirrhosis. The aim is to study the correlations between the gut microbiota taxa and muscle mass level in cirrhosis.

Methods: The study included 40 cirrhosis patients including 18 patients with sarcopenia.
