Polysulfide and persulfide-mediated activation of the PERK-eIF2α-ATF4 pathway increases Sestrin2 expression and reduces methylglyoxal toxicity.

Unfolded protein response (UPR) is activated in cells under endoplasmic reticulum (ER) stress. One sensor protein involved in this response is PERK, which is activated through its redox-dependent oligomerization. Prolonged UPR activation is associated with the development and progression of various diseases, making it essential to understanding the redox regulation of PERK.

Resilience and emergence of pneumococcal serotypes and lineages in adults post-PCV13 in Spain: A multicentre study.

Background: Streptococcus pneumoniae causes invasive pneumococcal disease (IPD) in adults. The introduction of pneumococcal conjugate vaccines (PCVs) has reduced vaccine serotypes but has also led to the rise of non-vaccine serotypes. The aim of this study was to analyse pneumococcal lineages and their association with recent changes in IPD among adults in Spain.

Refractory phenotype of -sensitized asthma with bronchiectasis and allergic bronchopulmonary aspergillosis.

Background: Sensitization to mucus plugs, and bacterial colonization may coexist and relate to a refractory phenotype during follow-up in asthma with bronchiectasis and allergic bronchopulmonary aspergillosis (ABPA).

Objective: This study aimed to clarify the features of -sensitized refractory asthma with bronchiectasis and determine the refractory phenotype in this population and ABPA.

Methods: This study included cases of the oldest available -specific IgE data and chest computed tomography images from a nationwide survey of refractory asthma with bronchiectasis.

Mosquito populations originating from nonendemic areas have the potential to transmit recently emerging Japanese encephalitis virus genotype IV.

Japanese encephalitis virus (JEV) genotype IV (GIV) is one of the least common and most neglected genotypes worldwide, having been identified only on a few Indonesian islands until it was recently found to be the cause of outbreaks that occurred in several Australian states in early 2022. Given the limited availability of information, the vector range for JEV GIV remains unknown; thus, understanding this range could prove invaluable for future prevention efforts in new areas. Herein, we experimentally exposed four mosquito colonies originated from various countries with no previous reports of GIV to JEV GIV strain 19CxBa-83-Cv, which was isolated from Theobald collected in Bali in 2019.

Automated method of bronchus and artery dimension measurement in an adult bronchiectasis population.

Aim: Bronchiectasis (BE) is a disease defined by irreversible dilatation of the airway. Computed tomography (CT) plays an important role in the detection and quantification of BE. The aim of this study was three-fold: 1) to assess bronchus-artery (BA) dimensions using fully automated software in a cohort of BE disease patients; 2) to compare BA dimensions with semi-quantitative BEST-CT (Bronchiectasis Scoring Technique for CT) scores for BE and bronchial wall thickening; and 3) to explore the structure-function relationship between BA-method lumen dimensions and spirometry outcomes.

Efficacy and safety of mosunetuzumab monotherapy for Japanese patients with relapsed/refractory follicular lymphoma: FLMOON-1.

Background: In a global phase I/II study (GO29781; NCT02500407), single-agent mosunetuzumab had a manageable safety profile and induced durable complete responses in patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma, including in patients with R/R follicular lymphoma (FL). In this analysis, the efficacy and safety of mosunetuzumab monotherapy were evaluated in an expansion cohort, FLMOON-1, in Japanese patients with R/R FL who had received  ≥ 2 prior lines of therapy in a phase I study (JO40295, jRCT2080223801).

Methods: Mosunetuzumab was administered intravenously at the recommended phase II dose (with cycle 1 step-up dosing) for eight cycles or up to 17 cycles, or until disease progression or unacceptable toxicity.

Development of a simple high-performance liquid chromatography-ultraviolet detection method for selpercatinib determination in human plasma.

Selpercatinib is a selective rearranged during transfection (RET) kinase inhibitor effective for the treatment of RET-positive non-small cell lung cancer, thyroid cancer, and other cancers. However, its clinical use requires careful management because of dose-dependent adverse effects and pharmacokinetic interactions. Given the multiple factors influencing selpercatinib blood levels, we hypothesized that establishing a therapeutic drug monitoring system for selpercatinib could help reduce adverse events and optimize efficacy.

Clinical usefulness of an ultra-high-sensitivity hepatitis B surface antigen assay to determine the cessation of treatment for HBV reactivation.

Introduction And Objectives: We aimed to compare the usefulness of the ultra-high-sensitivity hepatitis B surface antigen (iTACT-HBsAg), high-sensitivity hepatitis B core-related antigen (iTACT-HBcrAg), and anti-HBs assays in determination of cessation of nucleot(s)ide analogue (NA) treatment to prevent against hepatitis B virus (HBV) reactivation.

Patients And Methods: Twenty-two patients who developed HBV reactivation under immunosuppressive therapy or chemotherapy and had been administered NA and subsequently discontinued were enrolled. The stored serum samples taken at NA cessation were applied to iTACT-HBsAg (lower limit of detection; 0.

Assessment of mumps virus-specific antibodies: Comparison of three different enzyme immunoassays and neutralization test.

Introduction: We evaluated the application of a newly improved enzyme immunoassay (EIA) kit, Mumps IgG Seiken®, by comparing antibody responses to different EIA kits, and neutralization tests (NTs), using clinical samples.

Methods: Serum samples were collected before and 4-6 weeks after vaccination from 128 children who had no history of mumps or mumps vaccination. Using three different EIA kits, Mumps IgG Seiken®, a commercial kit from Enzygnost®, and an in-house kit, mumps-specific IgG antibodies were measured.

Ultra-Sensitive Quantification of Coproporphyrin-I and -III in Human Plasma Using Ultra-Performance Liquid Chromatography Coupled to Quadrupole Time-of-Flight Mass Spectrometry.

Organic anion transporting polypeptides (OATP) 1B1 and 1B3 are expressed in liver cells and are involved in drug uptake in the liver. OATP1B activity varies due to polymorphisms and is decreased by OATP1B inhibitors. Variability of OATP1B activity impacts the pharmacokinetics of OATP1B substrate drugs through drug-drug interactions.

Meroterpenoids with BACE1-inhibitory activity from the fruiting bodies of Suillus bovinus and Boletinus cavipes.

Alzheimer disease (AD) is the most common type of dementia and accounts for the largest proportion of dementia cases. The amyloid cascade hypothesis is known for the pathogenesis of AD, in which excessive accumulation of amyloid-β (Aβ) leads to the formation of senile plaques and ultimately to AD. Inhibition of β-secretase (BACE1) may contribute to the treatment of AD by suppressing Aβ production.

Inhibition of amyloid β aggregation and BACE1, and protective effect on SH-SY5Y cells, by p-terphenyl compounds from mushroom Thelephora aurantiotincta.

The number of patients with Alzheimer's disease (AD) is expected to increase as the population ages. The amyloid cascade hypothesis is proposed as the pathogenic mechanism of AD. We report the isolation and structural determination of three new p-terphenyl compounds, thelephantin P (1), thelephantin Q (2), and thelephantin R (3), with four known compounds (4-7), from the fruiting bodies of Thelephora aurantiotincta Corner.

Treatment Approaches for Carbapenem-Resistant Acinetobacter baumannii Infections.

Carbapenem-resistant Acinetobacter baumannii has been associated with over three hundred thousand annual deaths globally. It is resistant to most available antibiotics and associated with high morbidity and mortality. No global consensus currently exists for treatment strategies that balance safety and efficacy because of heterogeneity of treatment regimens in current clinical practice and scarcity of large-scale controlled studies arising from difficulties in establishing robust clinical outcomes.

Discriminant analysis of occupational performance characteristics in patients with major depressive disorders and healthy individuals.

Aim: Assessing symptoms and daily functioning in patients with major depressive disorder (MDD) can be challenging, as their limited self-monitoring abilities may result in behavior observed during structured interviews not accurately reflecting their daily lives. This study aimed to determine if specific occupational behaviors could distinguish individuals with MDD from healthy individuals.

Methods: Baseline data were collected from medical records and activity programs.
