Introduction: The late autumn epizootic of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in Serbia in 2023 caused massive mortality in the migratory population of common cranes (). This is the first time HPAIV has been identified in the common crane in Serbia, leading to mass mortality of this bird species.

Methods: To understand the pathological impact of HPAIV in cranes, we evaluated the pathological changes in the tissues of common cranes.

Community-acquired respiratory viral infections (CARV) significantly impact patients with hematological malignancies (HM), leading to high morbidity and mortality. However, large-scale, real-world data on CARV in these patients is limited. This study analyzed data from the EPICOVIDEHA-EPIFLUEHA registry, focusing on patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season.

Dipole toroidal modes appear in many fields of physics. In nuclei, such a mode was predicted more than 50 years ago, but clear experimental evidence was lacking so far. Using a combination of high-resolution inelastic scattering experiments with photons, electrons, and protons, we identify for the first time candidates for toroidal dipole excitations in the nucleus ^{58}Ni and demonstrate that transverse electron scattering form factors represent a relevant experimental observable to prove their nature.

Honey can benefit from non-thermal processing techniques such as high-pressure processing (HPP) to improve its quality and bioactivity. This study investigated the impact of HPP (600 MPa for 5, 10, and 15 min) on honey's quality, including the levels of hydroxymethylfurfural (HMF), antioxidant activity, total phenolic content (TPC), and phenolic profile. HPP treatment did not significantly affect HMF or TPC levels but led to selective changes in the phenolic profile.

Development of chiral organic materials with a strong chiroptical response is crucial to advance technologies based on circularly polarized luminescence, enantioselective sensing, or unique optical signatures in anti-counterfeiting. The progress in the field is hampered by the lack of structure-property relationships that would help designing new chiral molecules. Here, we address this challenge by synthesis and investigation of two chiral macrocycles that integrate in their structure a pseudo-meta [2.

February 2025

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

The properties of soil colloids determine the interaction with nanoparticles, their behavior, and destiny in the soil environment including soil solutions. This study examines how several properties of soil colloids, including pH, phosphorus content, clay minerals, and iron oxyhydroxides, influence the interaction with zinc oxide nanoparticles (ZnO-nps). For the experimental setup, four different soils were selected from the temperate climate of central Europe, in Slovakia, exhibiting pH values ranging from 4.

Purpose: This study was aimed at comprehensive genomic analysis of VIM-type carbapenemase-producing Klebsiella pneumoniae species complex (KpSC) in Poland.

Methods: All non-duplicate 214 VIM-producing KpSC isolates reported in Poland in 2006-2019 were short-read sequenced and re-identified by the average nucleotide identity scoring. Their clonality/phylogeny was assessed by cgMLST and SNP in comparison with genomes from international databases.

Laboratory measurements used for safety assessments in clinical trials are subject to the limits of the used laboratory equipment. These limits determine the range of values which the equipment can accurately measure. When observations fall outside the measurable range, this creates a problem in estimating parameters of the normal distribution.

Article Synopsis
  • Caenorhabditis elegans is being explored as a tool for chemotaxis testing due to its sensitive olfactory system, especially in cancer diagnostics.
  • This study aimed to assess the nematode's ability to differentiate between urine samples from healthy individuals and those with breast or colon cancer.
  • Results indicated a significant difference in the nematodes' responses, with high diagnostic sensitivity (96% for breast cancer, 100% for colon cancer) and moderate specificity (62%) in detecting cancer through urinary volatile organic compounds.

Article Synopsis
  • The text discusses the impact of pneumococcal conjugate vaccines (PCVs), specifically PCV10 and PCV13, on invasive pneumococcal disease (IPD) globally, highlighting how these vaccines have reduced the prevalence of disease caused by vaccine-type serotypes after extensive use.
  • It describes the methodology of data collection from various surveillance sites, which aimed to evaluate IPD cases that occurred five years after the vaccines were implemented, focusing on different age groups for analysis.
  • Findings indicate significant differences in serotype distribution between PCV10 and PCV13 sites; notably, certain serotypes, such as 19A and serotype 3, were prevalent in specific age groups, signaling ongoing challenges in controlling

Background: Pneumococcal conjugate vaccines (PCVs) that are ten-valent (PCV10) and 13-valent (PCV13) became available in 2010. We evaluated their global impact on invasive pneumococcal disease (IPD) incidence in all ages.

Methods: Serotype-specific IPD cases and population denominators were obtained directly from surveillance sites using PCV10 or PCV13 in their national immunisation programmes and with a primary series uptake of at least 50%.

Length-mass relationships of pond macroinvertebrates do not hold between Southern and Northern Europe.

PeerJ

December 2024

cE3c - Centre for Ecology, Evolution and Environmental Changes & CHANGE - Global Change and Sustainability Institute, Faculty of Sciences, University of Lisbon, Lisbon, Portugal.

The lack of reliable data on length-mass relationships, essential to obtain accurate biomass estimates, limits our ability to easily assess secondary production by aquatic invertebrates. In the absence of published equations from similar habitat conditions, authors often borrow equations developed in geographic regions with different climate conditions, which may bias biomass estimates. A literature overview of published size-mass relationships for Portugal and Sweden highlights the need for further data within these biogeographic regions.

Background: There is a high probability of compassion fatigue occurring in helping professionals who work with traumatized clients or patients. Several instruments exist for measuring compassion fatigue, but all of them have methodological flaws. The original Compassion Satisfaction/Fatigue Self-Test for Helpers is time-consuming and its psychometric properties, including factor structure, have not been supported in the research.

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.

Objective: Ultra-marathon running races are held as distance-limited or time-limited events, ranging from 6 h to 10 days. Only a few runners compete in 10-day events, and so far, we have little knowledge about the athletes' origins, performance, and event characteristics. The aim of the present study was to investigate the origin and performance of these runners and the fastest race locations.

Article Synopsis
  • Osteoarthritis (OA) is common and currently lacks effective treatments that can both modulate the immune response and repair cartilage, prompting research into extracellular vesicles (EVs) from blood-derived products like platelet poor plasma (PPP).
  • This study examined how PPP-derived EVs affect OA chondrocytes in a lab setting, revealing that these EVs possess anti-inflammatory properties and can significantly reduce the expression of certain inflammatory genes associated with OA.
  • The findings suggest that PPP-EVs can potentially be developed as a new type of treatment for OA, offering promise for better management of the disease in the future.
