Proteasomal processing of the viral replicase ORF1 facilitates HEV-induced liver fibrosis.

Chronic infections with hepatitis E virus (HEV), especially those of genotype 3 (G3), frequently lead to liver fibrosis and cirrhosis in patients. However, the causation and mechanism of liver fibrosis triggered by chronic HEV infection remain poorly understood. Here, we found that the viral multiple-domain replicase (ORF1) undergoes unique ubiquitin-proteasomal processing leading to formation of the EV-erived MAD ctivator (HDSA), a viral polypeptide lacking putative helicase and RNA polymerase domains.

Induction of mitochondrial damage via the CREB3L1/miR-34c/COX1 axis by porcine epidemic diarrhea virus infection facilitates pathogenicity.

Porcine epidemic diarrhea virus (PEDV) is a primary cause of viral diarrhea in neonatal piglets, leading to substantial economic losses in the swine industry globally. It primarily targets epithelial cells of the small intestine, compromising intestinal function and resulting in the death of affected animals. As mitochondria are essential for maintaining gut health, this study investigates the effects of PEDV infection on mitochondrial function in small intestinal epithelial cells and its subsequent impacts.

E3 ubiquitin ligase MARCH5 positively regulates Japanese encephalitis virus infection by catalyzing the K27-linked polyubiquitination of viral E protein and inhibiting MAVS-mediated type I interferon production.

Membrane-associated RING-CH-type finger (MARCH) proteins, a class of E3 ubiquitin ligases, have been reported to be involved in the infection of multiple viruses and the regulation of type I interferon (IFN) production. However, the specific role and mechanisms by which MARCH proteins influence Japanese encephalitis virus (JEV) infection remain poorly understood. Here, we systematically investigate the functional relevance of MARCH proteins in JEV replication by examining the effects of siRNA-mediated knockdown of MARCHs on viral infection.

Systematic review on evaluation tools applicable to One Health surveillance systems: A call for adapted methodology.

Developing and implementing effective surveillance programs for infectious diseases (ID) and antimicrobial resistance (AMR) requires the integration of information across relevant disciplines and sectors. Yet, establishing and sustaining collaboration at each step of the surveillance process, and modalities to translate integrated surveillance results into actions, are not well understood. This systematic review was designed to map and explore peer-reviewed tools that were either designed or used for evaluation of integrated surveillance systems for ID or AMR, and to identify the limitations of these tools and remaining methodological or knowledge gaps.

Detection of antimicrobial resistance via state-of-the-art technologies versus conventional methods.

Antimicrobial resistance (AMR) is recognized as one of the foremost global health challenges, complicating the treatment of infectious diseases and contributing to increased morbidity and mortality rates. Traditionally, microbiological culture and susceptibility testing methods, such as disk diffusion and minimum inhibitory concentration (MIC) assays, have been employed to identify AMR bacteria. However, these conventional techniques are often labor intensive and time consuming and lack the requisite sensitivity for the early detection of resistance.

Effects and potential pathways of goose astrovirus infection on gosling hepatic lipid metabolism.

Introduction: The adverse effects of goose astrovirus (GoAstV) on avian growth and health have been widely reported previously, while the stress reactions and corresponding mechanism of gosling liver responding to GoAstV infection remain not entirely clear.

Methods: One-day-old goslings inoculated subcutaneously with 2 × 10 TCID of GoAstV were employed as an experimental model, and the potential effects and pathways of GoAstV infection on gosling liver functions were investigated by combining the morphological, biochemical and RNA sequencing (RNA-seq) techniques.

Results: Structural and functional impairments were found in gosling livers post the virus infection, as characterized by the histological alterations in liver index and morphology of hepatic cord and sinuses, as well as the abnormal expression patterns of the cellular antioxidant, inflammation and apoptosis-related genes.

To address this issue, quantitative model of plant-plant interactions was established in three intercropping systems across 4 years.

Effects of organic acid-preserved cereal grains in sow diets during late gestation and lactation on the performance and faecal microbiota of sows and their offspring.

Background: Organic acids (OA) and maternal nutritional strategies have been demonstrated to promote piglet health and development. The objective of this study was to investigate the effects of incorporating OA-preserved cereal grains into sow diets during late gestation and lactation, aiming to reduce the metabolic demands of lactation while optimising offspring development and growth until slaughter. The experiment compared OA-preserved wheat and barley to conventionally dried grains, focusing on sow and offspring performance, as well as their faecal microbiota during lactation.

Food waste used as a resource can reduce climate and resource burdens in agrifood systems.

Global food loss and waste continues to increase despite efforts to reduce it. Food waste causes a disproportionally large carbon footprint and resource burdens, which require urgent action to transition away from a disposal-dominated linear system to a circular bioeconomy of recovery and reuse of valuable resources. Here, using data from field-based studies conducted under diverse conditions worldwide, we found collective evidence that composting, anaerobic digestion and repurposing food waste to animal feed (re-feed) result in emission reductions of about 1 tCOe t food waste recycled compared with landfill disposal.

BRACO-19 targeted the G-quadruplex in the 3'UTR of the Cucumber mosaic virus 1a, 2b, and CP genes to inhibit viral proliferation.

Background: The development of highly efficient and environmentally friendly plant virus inhibitors with novel structures mostly depends on the discovery of new targets. G-quadruplexes are non-classical high-level structures that are formed by guanine-rich nucleic acid sequences, which have significant biological functions. Small molecules that target the G-quadruplexes in the genomes of animal viruses have been shown to inhibit viral proliferation.
