Background: Chronic rhinosinusitis (CRS) is a persistent inflammatory disease of various endotypes, including eosinophilic CRS (eCRS), which is characterized by marked eosinophilic infiltration and high refractory rates despite treatment. Recent findings suggest the interaction between local IgE and mast cells in nasal polyps (NPs) is key to eCRS pathogenesis; however, the details remain unclear. This study investigated the involvement of MS4A2, a component of the IgE receptor, in the pathogenesis of refractory eCRS.

Retrotransposon Gag-like 4 (), a gene acquired from a retrovirus, is a causative gene in autism spectrum disorder. Its knockout mice exhibit increased impulsivity, impaired short-term spatial memory, failure to adapt to novel environments, and delayed noradrenaline (NA) recovery in the frontal cortex. However, due to its very low expression in the brain, it remains unknown which brain cells express RTL4 and its dynamics in relation to NA.

The lifecycle of schistosomes must be continuously maintained to clarify and understand this parasite in various aspects in laboratory settings. In the previous studies by other researchers, preservation of schistosome larvae or eggs was attempted by freezing with liquid nitrogen or organic chemicals, but frozen schistosomes were substantially impaired. The present study was conducted to determine whether schistosome eggs can be preserved under a non-frozen condition.

The SARS-CoV-2 pandemic alerted the potential for significant harm due to future cross-species transmission of various animal coronaviruses to human. There is a significant need of antibody-based drugs to treat patients infected with previously unseen coronaviruses. In this study, we generated CV804, an antibody that binds to the S2 domain of SARS-CoV-2 spike protein, which is highly conserved across the coronavirus family and less susceptible to mutations.

Saliva has antioxidant properties, washes away food residues, and helps maintain the oral environment; thus, decreased saliva secretion can have negative consequences. This study examined how slow-soluble innovative candy, named low-solubility amorphous material, affects oral indices such as saliva secretion and halitosis in a randomized, double-blind, placebo-controlled, crossover comparative study. Twenty-four healthy individuals with low saliva production were given one piece of low-solubility amorphous material or placebo candy and their saliva secretion was measured over 20 min.

Article Synopsis
  • - The study examined the role of programmed cell death-ligand 1 (PD-L1) expression and epidermal growth factor receptor (EGFR) mutations as biomarkers for lung adenocarcinoma, analyzing data from 847 patients across 21 centers in Japan from 2015 to 2018.
  • - Results showed that while PD-L1 expression was linked to shorter recurrence-free survival (RFS) in both EGFR-mutant and wild-type patients, it had no effect on overall survival (OS) in EGFR-mutant patients.
  • - The findings suggest that PD-L1 expression is a poor predictor of OS for EGFR-mutant patients and does not influence the effectiveness of post-relapse treatment with EGFR-

Xerostomia induced by antidepressants such as imipramine has long been thought to be due to their anticholinergic effects. However, even antidepressants with low anticholinergic effects may have a high incidence of xerostomia. In salivary glands, norepinephrine activates alpha-adrenergic receptors in blood vessels and beta-adrenergic receptors in acinar cells, respectively, causing a decrease in the blood flow and an increase in the protein secretion, resulting in the secretion of viscous saliva with low water content and high protein content.

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the suggestion that Ryugu/CI chondrites formed in a different region of the accretion disk, possibly around the orbits of Uranus and Neptune. We show that, like for Fe, Ryugu and CI chondrites also have indistinguishable Ni isotope anomalies, which differ from those of other carbonaceous chondrites. We propose that this unique Fe and Ni isotopic composition reflects different accretion efficiencies of small FeNi metal grains among the carbonaceous chondrite parent bodies.

Ryugu is the C-type asteroid from which material was brought to Earth by the Hayabusa2 mission. A number of individual grains and fine-grained samples analysed so far for noble gases have indicated that solar wind and planetary (known as P1) noble gases are present in Ryugu samples with concentrations higher than those observed in CIs, suggesting the former to be more primitive compared to the latter. Here we present results of analyses of three fine-grained samples from Ryugu, in one of which Xe concentration is an order of magnitude higher than determined so far in other samples from Ryugu.
