Discovery of viruses and bacteria associated with swine respiratory disease on farms at a nationwide scale in China using metatranscriptomic and metagenomic sequencing.

Respiratory disease (RD) is a worldwide leading threat to the pig industry, but there is still limited understanding of the pathogens associated with swine RD. In this study, we conducted a nationwide genomic surveillance on identifying viruses, bacteria, and antimicrobial resistance genes (ARGs) from the lungs of pigs with RD in China. By performing metatranscriptomic sequencing combined with metagenomic sequencing, we identified 21 viral species belonging to 12 viral families.

Knowledge, attitudes, and practices among physicians and pharmacists toward antibiotic use in sepsis.

Background: Sepsis management in the Intensive Care Unit (ICU) presents a significant challenge within contemporary healthcare. The primary challenge lies in ensuring the timely and appropriate utilization of antibiotics. Inappropriate antibiotic use in sepsis management can result in a multitude of adverse outcomes.

3D-Printed PCL/SrHA@DFO Bone Tissue Engineering Scaffold with Bone Regeneration and Vascularization Function.

The application of a three-dimensional (3D)-printed biological functional scaffold in the repair of bone defects is a promising strategy. In this study, strontium-containing hydroxyapatite (SrHA) powder was synthesized by the hydrothermal method, and then poly(ε-caprolactone) (PCL)/HA and PCL/SrHA composite scaffolds were prepared by the high-temperature melt extrusion 3D printing technology. The basic physical and chemical properties, in vitro biological properties, osteogenesis, and angiogenesis abilities of the scaffold were studied.

Unraveling the interaction of dissolved organic matter and microorganisms with internal phosphorus cycling in the floodplain lake ecosystem.

Internal nutrient cycling, especially phosphorus (P), is of great influence in lake eutrophication. Dissolved organic matter (DOM) and microorganisms are ubiquitous in the sediments and closely associated with P-cycling. However, the underlying interactions of DOM, microorganisms and P in floodplain lake area with different hydrological characteristics remain scarce.

Targeting membrane integrity and imidazoleglycerol-phosphate dehydratase: Sanguinarine multifaceted approach against Staphylococcus aureus biofilms.

Background: Staphylococcus aureus is an opportunistic pathogen capable of readily forming biofilms, which can result in life-threatening infections involving different organs. Sanguinarine are benzo[c]phenanthridine alkaloids extracted from the Sanguinaria canadensis L. (Papaveraceae), which have a wide range of biological activities.
