Historical trends of metals and metalloids into lake and coastal sediments of Halong Bay (Vietnam).

Halong Bay (northern Vietnam) is heavily affected by human activities. Metals and metalloids (e.g.

Blocking autophagosome closure manifests the roles of mammalian Atg8-family proteins in phagophore formation and expansion during nutrient starvation.

Macroautophagy/autophagy, an evolutionarily conserved cellular degradation pathway, involves phagophores that sequester cytoplasmic constituents and mature into autophagosomes for subsequent lysosomal delivery. The gene family, comprising the and subfamilies in mammals, encodes ubiquitin-like proteins that are conjugated to phagophore membranes during autophagosome biogenesis. A central question in the field is how Atg8-family proteins are precisely involved in autophagosome formation, which remains controversial and challenging, at least in part due to the short lifespan of phagophores.

Exploring the Synergistic Effects of Erinacines on Microglial Regulation and Alzheimer's Pathology Under Metabolic Stress.

Background: Hericium erinaceus mycelium and its constituents, erinacines A and S, have shown neuroprotective effects in APP/PS1 transgenic mice; however, the precise mechanisms by which they modulate microglial phenotypes remain unclear. Our study is the first to explore the effect of erinacines on microglia morphology and the underlying mechanisms using a novel primary mixed glia cell model and advanced bioinformatic tools. Furthermore, we emphasize the clinical relevance by evaluating erinacines in a metabolically stressed APP/PS1 mouse model, which more accurately reflects the complexities of human Alzheimer's disease (AD), where metabolic syndrome is a common comorbidity.

Detection of antibodies against H5 subtype highly pathogenic avian influenza viruses in multiple raccoons in Tokachi District, Hokkaido, Japan, from 2022 to 2023.

In recent years, infection cases of H5 subtype highly pathogenic avian influenza viruses (HPAIVs) in wild mammals have increased globally. To obtain recent epidemiological information regarding influenza A virus (IAV) infection in raccoons (Procyon lotor), the prevalence of anti-IAV antibodies in sera was analyzed among raccoons captured in Tokachi District, Hokkaido, Japan, from 2019 to 2023. Screening of serum samples using enzyme-linked immunosorbent assay and agar gel precipitation test detected anti-IAV antibodies in 5 of 114 (4.

Agent-based modelling of Mycobacterium tuberculosis transmission: a systematic review.

Background: Traditional epidemiological models tend to oversimplify the transmission dynamics of Mycobacterium tuberculosis (M.tb) to replicate observed tuberculosis (TB) epidemic patterns. This has led to growing interest in advanced methodologies like agent-based modelling (ABM), which can more accurately represent the complex heterogeneity of TB transmission.
