Reactor-emitted electron antineutrinos can be detected via the inverse beta decay reaction, which produces a characteristic signal: a two-fold coincidence between a prompt positron event and a delayed neutron capture event within a specific time frame. While liquid scintillators are widely used for detecting neutrinos reacting with matter, detection is difficult because of the low interaction of neutrinos. In particular, it is important to distinguish between neutron (n) and gamma (γ) signals.

Previously undescribed benzophenone rhamnosides, triadenosides A-F (1-6), were isolated from the aerial parts of Triadenum japonicum (Blume) Makino (Hypericaceae), where known compounds including benzophenone rhamnosides (7 and 8), benzophenone C-glucoside (9), flavonols and their glycosides (10-17), and biflavone (18) were also isolated and identified. Detailed spectroscopic analysis revealed that triadenoside A (1) was 2,3',5'-trihydroxy-4,6-dimethoxybenzophenone 2-O-α-L-rhamnopyranoside, while the absolute configuration of the rhamnosyl moiety was confirmed by HPLC analysis. Triadenosides B-E (2-5) were assigned as acetyl derivatives of 1 in their rhamnosyl moieties.

Article Synopsis
  • A study analyzed data from 7,301 Korean adults to explore the link between periodontitis (a gum disease) and different body size categories based on body mass index and metabolic health status.
  • Participants were divided into four groups: metabolically healthy normal weight, metabolically abnormal normal weight, metabolically healthy obese, and metabolically abnormal obese.
  • The findings revealed that periodontitis was more common among those in the metabolically abnormal groups, indicating that having a higher body mass index and metabolic issues increases the risk of gum disease; thus, addressing metabolic health may improve periodontal disease outcomes.

The novel coronavirus disease 2019 has stimulated the rapid development of new biological therapeutics to inhibit SARS-CoV-2 infection; however, this remains a challenging task. In a previous study using structural analysis, we revealed that human cyclophilin A inhibits the entry of SARS-CoV-2 into host cells by interfering with the interaction of the receptor-binding domain of the spike protein with angiotensin-converting enzyme 2 on the host cell surface, highlighting its potential for antiviral therapy. For a comprehensive experimental validation, in this study, we verified the antiviral effects of human cyclophilin A against SARS-CoV-2, including its variants, using in vitro assays and experiments on an in vivo mouse model.

Seasonal influenza results in 3 to 5 million cases of severe disease and 250,000 to 500,000 deaths annually. Macrophages have been implicated in both the resolution and progression of the disease, but the drivers of these outcomes are poorly understood. We probed mouse lung transcriptomic datasets using the Digital Cell Quantifier algorithm to predict immune cell subsets that correlated with mild or severe influenza A virus (IAV) infection outcomes.

Genetically engineered mouse models (GEMMs) help us to understand human pathologies and develop new therapies, yet faithfully recapitulating human diseases in mice is challenging. Advances in genomics have highlighted the importance of non-coding regulatory genome sequences, which control spatiotemporal gene expression patterns and splicing in many human diseases. Including regulatory extensive genomic regions, which requires large-scale genome engineering, should enhance the quality of disease modelling.

Type 2 cytokines like IL-4 are hallmarks of helminth infection and activate macrophages to limit immunopathology and mediate helminth clearance. In addition to cytokines, nutrients and metabolites critically influence macrophage polarization. Choline is an essential nutrient known to support normal macrophage responses to lipopolysaccharide; however, its function in macrophages polarized by type 2 cytokines is unknown.

Human cyclophilin A (hCypA) is important for the replication of multiple coronaviruses (CoVs), and cyclosporine A inhibitors can suppress CoVs. The emergence of rapidly spreading severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants has sparked concerns that mutations affect the binding ability of the spike (S) protein to the angiotensin-converting enzyme 2 (ACE2) cell receptor, affecting the severity of coronavirus disease (COVID-19). Far-western blotting and surface plasmon resonance (SPR) results revealed that hCypA interacts strongly with the viral SARS-CoV-2 receptor-binding domain (RBD), with a binding affinity of 6.
