Bats are recognized as natural reservoirs for an array of diverse viruses, particularly coronaviruses, which have been linked to major human diseases like SARS-CoV and MERS-CoV. These viruses are believed to have originated in bats, highlighting their role in virus ecology and evolution. Our study focuses on the molecular characterization of bat-derived coronaviruses (CoVs) in Canada.
View Article and Find Full Text PDFAfrican swine fever virus (ASFV) is a devastating disease affecting domestic and wild suids and causing significant economic losses in the global pig industry. Attenuated modified live virus (MLV) vaccines are the most promising approaches for vaccine development. This study aimed to evaluate the safety and efficacy of four recombinant ASFV genotype II strains, derived from the non-hemadsorbing (non-HAD) attenuated isolate Lv17/WB/Rie1, through the single or simultaneous deletion of virulence-associated genes.

Pediatric guidelines recommend monotherapy with an antipseudomonal beta-lactam or a carbapenem and to add a second anti-Gram-negative agent in selected situations. We evaluated the changes in the proportions of resistance of beta-lactam monotherapies vs.

- The Chironomidae family, consisting of over 7,300 species, is a highly diverse group of insects found in freshwater ecosystems globally, with documentation varying greatly across Europe.
- This study enhances the understanding of chironomid fauna in three catchments in Croatia, Hungary, and Czechia, identifying 207 taxa, including 14 species new to Croatia and two to Czechia.
- Techniques like DNA barcoding revealed 23 new genetic groups, emphasizing the importance of focused field studies on challenging taxa to improve both local and global knowledge of these insects.
Background: The histone gene H2AX and its phosphorylated protein γ-H2AX play a crucial role in the DNA damage response. This study investigates the expression of H2AX mRNA and its phosphorylated γ-H2AX protein in oropharyngeal squamous cell carcinoma (OPSCC), its association with distinct biological pathway alterations and its potential as a biomarker.
Materials And Methods: Expression of H2AX mRNA in 76 OPSCC from The Cancer Genome Atlas (TCGA) cohort was analyzed.
