Autistic symptoms and clinical features of individuals at clinical high risk for psychosis and first-episode psychosis.

Introduction: Autistic symptoms in schizophrenia are reportedly associated with cognitive and social functions. However, few studies have investigated the association between autistic symptoms and clinical features in individuals with a clinical high risk for psychosis (CHR-P) and first-episode psychosis (FEP). We aimed to determine the association between autistic symptoms and clinical features in a cohort of individuals with CHR-P or FEP.

Detection of the nuclear translocation of androgen receptor using quantitative and automatic cell imaging analysis.

Testosterone signaling mediates diseases such as androgenetic alopecia and prostate cancer and is controlled by the activation of the androgen receptor (AR) and nuclear translocation of the ligand-receptor complex. This study established an immortalized dermal papilla cell line that stably expresses the AR labeled with a monomeric green fluorescence marker. The cells expressed the histone H2B protein as visualized using a red fluorescence marker, enabling the Detection of nuclear translocation under live cell conditions using image analysis.

Developmental changes in lower limb joint ranges of motion in Japanese children aged 6-15 years.

Background: Assessing lower limb ranges of motion (ROMs) is crucial for diagnosing and treating musculoskeletal and neurological disorders in children. Although prior studies examining decline in flexibility among school-age children suggest potential age-related changes in lower limb ROMs, this hypothesis remains unproven. Therefore, in this study, we aim to examine age-related differences in lower limb ROMs among school-age children.

Effect of Organic Anion Transporting Polypeptide 1B1 on Plasma Concentration Dynamics of Clozapine in Patients with Treatment-Resistant Schizophrenia.

The involvement of drug-metabolizing enzymes and transporters in plasma clozapine (CLZ) dynamics has not been well examined in Japanese patients with treatment-resistant schizophrenia (TRS). Therefore, this clinical study investigated the relationship between single nucleotide polymorphisms (SNPs) of various pharmacokinetic factors (drug-metabolizing enzymes and transporters) and dynamic changes in CLZ. Additionally, we aimed to determine whether CLZ acts as a substrate for pharmacokinetic factors using in vitro assays and molecular docking calculations.

Relationship Between Clozapine-Induced Inflammation and Eosinophilia: A Retrospective Cohort Study.

Background And Hypothesis: Eosinophilia has not been highlighted in clozapine-induced adverse inflammatory events, as it is often asymptomatic and self-limiting, while drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome occurs rarely. This study aimed to reveal the temporal relationships between eosinophilia and other inflammatory events during clozapine initiation.

Study Design: The temporal relationships between eosinophilia and other inflammatory events were evaluated among 241 patients with schizophrenia treated with clozapine for the first time at 7 hospitals.
