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.

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.

Designing well-defined magnetic nanomaterials is crucial for various applications, and it demands a comprehensive understanding of their magnetic properties at the microscopic level. In this study, we investigate the contributions to the total anisotropy of Mn/Co mixed spinel nanoparticles. By employing neutron measurements sensitive to the spatially resolved surface anisotropy with sub-Å space resolution, we reveal an additional contribution to the anisotropy constant arising from shape anisotropy and interparticle interactions.

Article Synopsis
  • MUC1 and UMOD pathogenic variants are linked to autosomal dominant tubulointerstitial kidney disease (ADTKD), with MUC1 associated with a significant reduction in mucin-1 production.
  • A survey conducted among ADTKD patients revealed that those with ADTKD-MUC1 had a higher rate of previous COVID-19 infections and COVID-related deaths compared to ADTKD-UMOD individuals.
  • The study concluded that individuals with ADTKD-MUC1 are eight times more likely to die from COVID-19, suggesting that lower mucin-1 levels may contribute to this increased risk.

Vacuum-Nitrogen Assisted (VANS) Topotactical Deintercalation for Extremely Fast Production of Functionalized Silicene Nanosheets.

Small

December 2024

Istituto per la Microelettronica e Microsistemi, Consiglio Nazionale delle Ricerche, Sede di Agrate Brianza, Via C. Olivetti 2, Agrate Brianza, I-20864, Italy.

Silicene, the analog of graphene composed of silicon atoms arranged in a honeycomb lattice, has garnered significant attention due to its unique properties, positioning it as a promising candidate for various applications in electronic devices, photovoltaics, photocatalysis, and biomedicals. While the chemical synthesis of silicene nanosheets has traditionally involved time-spending and expensive- methods, this study introduces a rapid vacuum/nitrogen cycle assisted (VANS) protocol that dramatically speeds up the production of silicene. The strategic implementation of vacuum/nitrogen cycles provides the efficient removal of the generated hydrogen, boosting the overall reaction kinetics while maintaining inert reaction conditions to prevent oxidation.
