Four salt-tolerant and aromatics degrading strains used in this study were isolated from polluted technogenic soil on the territory of the Verkhnekamsk potash deposit (Russia). The strains were aerobic, Gram-stain-positive, non-motile, non-endospore-forming irregular rods, exhibiting a marked rod-coccus growth cycle. They contained lysine-based peptidoglycan, teichulosonic acid and poly(glycosyl phosphate) polymers in the cell walls.

Enteroviruses (EV) are a highly diverse group of viruses multiplying primarily in the gastrointestinal tract and/or the upper respiratory tract, initially distributed in two separate genera: Enterovirus and Rhinovirus, respectively. According to the similarities in genome organization and particle structure, rhinovirus species were later reclassified as also belonging to genus Enterovirus. Human EV infections are usually asymptomatic or causing mild clinical manifestations.

In phylogenetic studies, both partitioned models and mixture models are used to account for heterogeneity in molecular evolution among the sites of DNA sequence alignments. Partitioned models require the user to specify the grouping of sites into subsets, and then assume that each subset of sites can be modelled by a single common process. Mixture models do not require users to pre-specify subsets of sites, and instead calculate the likelihood of every site under every model, while co-estimating the model weights and parameters.

As the effects of anthropogenic climate change have become more apparent, the influences of climate and extreme weather events on health have continued to gain attention. The fact Earth has warmed over the past century is indisputable and the rate of warming is more alarming. As a result of anthropogenic climate change an alteration in the air mixture has occurred over time.

The Crabtree effect in yeast, where cells prefer fermentation over respiration in high -glucose environments, is associated with mitochondrial repression, but the molecular mechanisms were previously unclear. Recently, Vengayil et al. revealed that knocking out the ubp3 gene, encoding a deubiquitinase enzyme, mitigates the Crabtree effect by increasing mitochondrial phosphate levels.

and are a sister species pair that have been used as a model for studies of reproductive isolation and speciation for almost 100 years owing to their close evolutionary history, well characterized genetic differences, and overlapping geographic distribution. There are extensive analyses of both pre- and post-zygotic isolation, including studies of courtship divergence, conspecific sperm precedence (CSP) and how reinforcement by natural selection may or may not act to strengthen isolation in sympatry. Post-zygotic analyses explore the underlying mechanics of reproductive isolation; how inversions may give rise to initial speciation events and misexpression of key genes typically found within inversion regions render hybrid offspring unfit or inviable.

Agricultural intensification coupled with changing climate are causing soils to become increasingly vulnerable to stresses such as drought, soil erosion, and compaction. The mechanisms by which roots detect and respond to soil stresses remain poorly understood. Recent breakthroughs show that roots release volatile and soluble hormone signals into the surrounding soil, then monitor their levels to sense soil stresses.

Telomere repeat-binding factor 2 (TRF2) is a key component of the shelterin complex which guards the integrity of the telomere. Most of the TRF2 discussed previously was focused on the telomere, and relatively less is discussed on aspects other than that. It is proved that TRF2 also localizes to other potential G-quadruplex-forming sequences among the whole genome besides the telomere.

According to the Trivers-Willard hypothesis (TWH), when the mother's condition around conception influences the future reproductive success of male and female offspring differently, the adjustment of offspring sex ratio (SR) to maternal condition will increase the parents' fitness. The TWH has been tested in several taxa, including humans where socioeconomic status as an index of condition has been widely used. The results are inconsistent, possibly because the preconditions of the TWH are not always met.

Genome editing and plant transformation are crucial techniques in plant biotechnology, allowing for the precise modification of plant genomes to enhance agronomically essential traits. The advancement of CRISPR-based genome editing tools in plants is limited, among others, by developing novel tissue culture methodologies for efficient plant genetic transformation. methodologies offer a promising alternative to overcome tissue culture limitations and facilitate crops' genetic improvement.

Background: Increased cardiac troponin (cTn) concentrations occur in acute myocardial injury and chronic diseases. Characterization of cTn composition in the circulation may assist in differentiating etiologies of myocardial injury. Our goal was to study cTn composition and kinetics in patients following type 1 myocardial infraction (T1MI), cardiac procedures, and chronic heart diseases to establish the relationship between cTn composition and clinical diagnosis.

Background: Current studies suggest that cardiac troponin (cTn) forms in the circulation may vary in different clinical scenarios. Our aim was to design a combination of cTn assays specific to the main cTn forms and to evaluate their analytical performance.
Methods: We developed immunoassays specific for measuring (1) long-cTnT cTnI-cTnT-TnC (ITC) ternary complex, with cTnT in long form without cleavage at the C-terminal amino acids residue 189-223, designated "long-cTnT ITC complex assay;" (2) both the long-cTnT ITC complex plus short-cTnT ITC complex, designated "hs-total ITC complex assay;" (3) the central part of cTnT of both the long-cTnT ITC complex and free cTnT, designated "hs-cTnT assay.

Altered energy metabolism in Alzheimer's disease (AD) is a major pathological hallmark implicated in the early stages of the disease process. Astrocytes play a central role in brain homeostasis and are implicated in multiple neurodegenerative diseases. Although numerous studies have investigated global changes in brain metabolism, redox status, gene expression and epigenetic markers in AD, the intricate interplay between different metabolic processes, particularly in astrocytes, remains poorly understood.

Passive acoustic monitoring (PAM) is an increasingly popular tool to study vocalising species. The amount of data generated by PAM studies calls for robust automatic classifiers. Deep learning (DL) techniques have been proven effective in identifying acoustic signals in challenging datasets, but due to their black-box nature their underlying biases are hard to quantify.

A tooth-bearing mandible fossil of a colobine monkey discovered at Shuitangba, Zhaotong, Yunnan, China, was morphometrically analyzed and compared with extant Asian colobines. Our previous qualitative and quantitative descriptions indicate that it can be safely attributed to Mesopithecus pentelicus, a Miocene fossil colobine widely found in Europe and South Asia. The present research aims to explore fossil association with extant colobines and functionally propose its dietary preferences based on multivariate morphometric analyses of mandibular morphology.
