-A152T mutation drives neuronal hyperactivity through Fyn-NMDAR signaling in human iPSC-Derived neurons: Insights into Alzheimer's pathogenesis.

Introduction: Tau protein plays a pivotal role in the pathogenesis of Alzheimer's disease (AD) and in regulating neuronal excitability. Among tau-coding microtubule associated protein tau () gene mutations, the A152T mutation is reported to increase the risk of AD and neuronal excitability in mouse models.

Methods: To investigate the effects of gene expression and its mutations on neuronal activity in human neurons, we employed genome editing technology to introduce the A152T or P301S mutations into induced pluripotent stem cells (iPSCs).

Withdrawal Dyskinesia Associated With Aripiprazole in a Child: A Case Report.

Atypical antipsychotics are considered to be better tolerated than typical antipsychotics; however, the risk of drug-induced movement disorders needs to be considered. Aripiprazole, a dopamine partial agonist, is one of the most frequently used atypical antipsychotics in children. In this report, we describe withdrawal dyskinesia after aripiprazole discontinuation in a child with autism spectrum disorder.

Sugar and arginine facilitate oral tolerance by ensuring the functionality of tolerogenic immune cell subsets in the intestine.

Although oral tolerance is a critical system in regulating allergic disorders, the mechanisms by which dietary factors regulate the induction and maintenance of oral tolerance remain unclear. To address this, we explored the differentiation and function of various immune cells in the intestinal immune system under fasting and ad libitum-fed conditions before oral ovalbumin (OVA) administration. Fasting mitigated OVA-specific Treg expansion, which is essential for oral tolerance induction.

Photodynamic diagnosis-assisted transurethral resection of bladder tumor for high-risk non-muscle invasive bladder cancer improves intravesical recurrence-free survival (BRIGHT study).

Objectives: In a primary analysis of data from the BRIGHT study (UMIN000035712), photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) using oral 5-aminolevulinic acid hydrochloride reduced residual tumors in high-risk non-muscle invasive bladder cancer (NMIBC). We aimed to evaluate the effectiveness of PDD-TURBT for intravesical recurrence after a second transurethral resection for high-risk NMIBC.

Methods: High-risk NMIBC patients initially treated with PDD-TURBT (PDD group) were prospectively registered between 2018 and 2020.
