Diversity of filariae circulating in South Caucasian bats and their ectoparasites.

Curr Res Parasitol Vector Borne Dis

August 2025

Department of Ecology and Diseases of Zoo Animals, Game, Fish and Bees, University of Veterinary Sciences Brno, Brno, Czech Republic.

Recent research on chiropteran parasites suggests a high prevalence and diversity, and extensive spatial distribution of filarial species; however, ecological and phylogenetic studies are still in their infancy. We sampled blood from 78 bat specimens, collected 1181 ectoparasites at summer colonies in Armenia and Georgia, and used nested-PCR targeting the cytochrome oxidase subunit 1 (1) gene to detect and genotype filarial parasites. The overall prevalence of filarial DNA was 17.

Transmembrane adenylyl cyclases (tmACs; ACs) are enzymes that synthesize cyclic AMP (cAMP), which is a key molecule in cellular signaling. Disruptions in AC activity can lead to long-term shifts in cAMP levels associated with various pathologies. In our study, we analyzed AC primary sequences and identified cholesterol-binding CARC and CRAC motifs located in conserved cytosolic regions, a surprising finding for motifs that are typically membrane-associated.

Two-dimensional ion-selective membranes provide an appealing avenue for extracting lithium from naturally occurring aqueous brine solutions. Most current work is focused on graphene-based membranes, where the dynamics of ion permeation is determined by noncovalent pore-ion interactions, and the main challenge is achieving precise control over the pore size. Here, we propose that porphyrins, macrocycles with atomically precise pores ∼2.

The mammary gland is a dynamic organ whose parenchyma undergoes major development during puberty and extensive remodeling with each estrous cycle. These processes can be modelled and investigated in vitro via 3D cell culture techniques that employ specialized extracellular matrices and appropriate growth factors. The resulting mammary organoid cultures faithfully represent the mammary gland with respect to cellular heterogeneity, cell-cell contacts, overall architecture as well as response to growth factor stimuli and are amendable to a variety of molecular methods as well as microscopy techniques.

This study aimed to develop a robust methodology for quantifying cortisol decay in segmented human hair and to establish accurate retrospective estimates of initial cortisol levels. Two independent probabilistic approaches were employed: i) a Bayesian multilevel analysis across 37 individuals with 3-6 hair segments each and ii) a Bayesian repeated sampling approach in a single individual with 10 segments collected over eight months. All hair segments were analyzed for cortisol concentration using liquid chromatography-mass spectrometry with on-line solid phase extraction.

IntroductionWound healing complications (WHC) of groin incisions are frequently discussed in vascular surgery. Various preventive measures are often applied to reduce their rates, but not all have the desired effect, and all these measures have their respective costs. The main aim of this study is to determine the effectiveness of closed incision negative pressure therapy (ciNPT) in reducing WHCs in high-risk patients after major revascularization procedures compared to the conventional adhesive dressing and to investigate the cost-benefit of its routine use.

Since the outbreak of SARS-CoV-2 in recent years, our society has become more aware that zoonotic diseases pose a real threat. Therefore, the demand for small molecules that target host proteins, essential for viral entry and replication, has increased as an interesting strategy for the development of antiviral agents, as these agents may be effective against several different pathogens. NAK kinases is one such potential target family because they are involved in a variety of cellular functions, hijacked by viruses to invade host cells, such as clathrin-mediated endocytosis.

Plants rely on tight coordination between nuclear, mitochondrial, and chloroplast genomes to form essential multi-enzyme cytonuclear complexes. Whole-genome duplication (WGD) doubles the nuclear genome, potentially disrupting cytonuclear stoichiometry unless organellar genomes respond accordingly. Targeted analyses of chloroplasts and mitochondria enabled us to dissect the extent and mechanisms of adjustments in both organelles immediately after WGD and across generations in Arabidopsis auto- and allopolyploids.

Reassessing the foundations of metric-affine gravity.

Eur Phys J C Part Fields

August 2025

DISAT, Politecnico di Torino-PoliTo, Corso Duca degli Abruzzi 24, 10129 Turin, Italy.

We reassess foundational aspects of Metric-Affine Gravity (MAG) in light of the Dressing Field Method, a tool allowing to systematically build gauge-invariant field variables. To get MAG started, one has to deal with the problem of "gauge translations". We first recall that Cartan geometry is the proper mathematical foundation for gauge theories of gravity, and that this problem never arises in that framework, which still allows to clarify the geometric status of gauge translations.
