Helminth diversity of nutria () across the Morava basin in the Czech Republic.

Parasitology

December 2024

Department of Forest Protection and Wildlife Management, Faculty of Forestry and Wood Technology, Mendel University in Brno, Brno, Czech Republic.

The nutria was introduced to Europe from South America and kept for the fur industry. This semiaquatic rodent became a well-established species in the Czech Republic; however, it still poses a significant threat to the native fauna, not only as a natural competitor but also as a vector of non-indigenous parasites. Our research aimed to investigate the diversity of endoparasitic helminths in nutria, with a particular focus on assessing the risk posed by helminth species with zoonotic potential.

P , T -odd effects in YbCu, YbAg, and YbAu.

J Chem Phys

December 2024

Van Swinderen Institute for Particle Physics and Gravity, University of Groningen, Nijenborgh 4, 9747 AG Groningen, The Netherlands.

In this work, the molecular enhancement factors of the P,T-odd interactions involving the electron electric dipole moment (Wd) and the scalar-pseudoscalar nucleon-electron couplings (Ws) are computed for the ground state of the bimetallic molecules YbCu, YbAg, and YbAu. These systems offer a promising avenue for creating cold molecules by associating laser-cooled atoms. The relativistic coupled-cluster approach is used in the calculations, and a thorough uncertainty analysis is performed to give accurate and reliable uncertainties to the obtained values.

The treatment of infections caused by is currently complicated by the increasing number of strains resistant to antimicrobial agents. One promising way to solve this problem is phage therapy. Due to the lack of data on the effectiveness and safety of phage preparations, STAFAL is the only registered phage preparation for the treatment of infectious diseases in the Slovak Republic and the entire European Union.

Stress responses can impact bladder cancer (BC) outcomes via immune-inflammatory pathway modulation. This study explores heart rate variability (HRV) associations with serum immune-inflammatory biomarkers, blood count inflammatory markers, and psychosocial self-report measures in patients versus healthy controls. The TREM-1 and TREM-2 expressions on peripheral blood monocytes were analysed via flow cytometry; serum inflammatory biomarkers by ELISA; HRV (5-min ECG) pre-tumour resection; blood counts by haematology analyser; and psychosocial factors by validated questionnaires.

Comparative Study of Water and Milk Kefir Grains as Biopolymeric Adsorbents for Copper(II) and Arsenic(V) Removal from Aqueous Solutions.

Polymers (Basel)

November 2024

Institute of Laboratory Research on Geomaterials, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynská dolina, Ilkovičova 6, 842 15 Bratislava, Slovakia.

This study investigates the biosorption capabilities of kefir grains, a polysaccharide-based byproduct of the fermentation process, for removing copper(II) and arsenic(V) from contaminated water. Unlike traditional heavy-metal removal methods, which are typically expensive and involve environmentally harmful chemicals, biopolymeric materials such as kefir grains provide a sustainable and cost-effective alternative for adsorbing hazardous inorganic pollutants from aqueous solutions. Our experimental results revealed significant differences in the sorption capacities of two types of kefir grains.

Wound healing represents a complex and evolutionarily conserved process across vertebrates, encompassing a series of life-rescuing events. The healing process runs in three main phases: inflammation, proliferation, and maturation/remodelling. While acute inflammation is indispensable for cleansing the wound, removing infection, and eliminating dead tissue characterised by the prevalence of neutrophils, the proliferation phase is characterised by transition into the inflammatory cell profile, shifting towards the prevalence of macrophages.

The ventricular system and subarachnoid space are filled with cerebrospinal fluid, which plays a key role in the nervous system. This fluid is produced by the choroid plexus, an organ rich in ion transporters that precisely control the transport of specific ions into the cerebrospinal fluid thanks to tight junctions between the plexus cells; these prevent the passage of substances other than the transporters, thus allowing for precise control of the fluid composition. Cerebrospinal fluid production is based on a network of interrelationships between specific ion flows enabled by the numerous transporters.

Asthma is a common multifaceted respiratory disease with a major impact on quality of life. Despite increased insights into mechanisms underlying various asthma phenotypes and endotypes and the availability of targeted biologic treatment options, the disease remains uncontrolled in a substantial proportion of patients with risk of exacerbations, requiring systemic corticosteroids, and with progressive disease. Current international guidelines advocate a personalized management approach to patients with uncontrolled severe asthma.

Obes Surg

January 2025

Department of Surgery, Transplantation and Gastroenterology, Division of Interventional Gastroenterology, Semmelweis University, Üllői Út 78, 1082, Budapest, Hungary.

Article Synopsis
  • The study compared three techniques for ERCP (endoscopic retrograde cholangiopancreatography) in patients who had undergone Roux-en-Y gastric bypass: enteroscopy-assisted (EA-ERCP), laparoscopy-assisted (LA-ERCP), and endoscopic ultrasound-directed (EDGE).
  • 67 studies were analyzed, showing that EDGE had the highest technical success rate at 96%, followed by LA-ERCP at 93%, and EA-ERCP at 77%, with significant differences between EA-ERCP and the other methods.
  • The overall rates of adverse events were similar across all techniques, suggesting that EDGE and LA-ERCP are both effective and as safe

Exposure to artificial light at night (ALAN) disrupts natural darkness and desynchronizes daily rhythms in physiological processes and behavior. Previously, in rats, we have shown that dim ALAN disturbed the central circadian control and the temporal organization of behavior, and hormonal and metabolic pathways. The measurements of undisturbed daily behavioral (locomotor activity, feeding and drinking) patterns revealed reduced amplitudes and a transitory activity peak in the middle of the light (i.

Article Synopsis
  • The study investigates the impact of Shank3 deficiency on dopaminergic neurons in mouse models relevant to autism.
  • Significant reductions in neurite outgrowth and altered morphology of dopaminergic neurons were observed in Shank3-deficient mice compared to wild-type (WT) mice.
  • Although there were no changes in the expression of synaptic proteins, shifts in dopaminergic receptor gene expression suggest structural alterations may contribute to autistic symptoms in these models.
