The Gene Product STIL Is Essential for Dendritic Spine Formation.

Dendritic spine formation/maintenance is highly dependent on actin cytoskeletal dynamics, which is regulated by small GTPases Rac1 and Cdc42 through their downstream p21-activated kinase/LIM-kinase-I/cofilin pathway. ARHGEF7, also known as ß-PIX, is a guanine nucleotide exchange factor for Rac1 and Cdc42, thereby activating Rac1/Cdc42 and the downstream pathway, leading to the upregulation of spine formation/maintenance. We found that STIL, one of the primary microcephaly gene products, is associated with ARHGEF7 in dendritic spines and that knockdown of resulted in a significant reduction in dendritic spines in neurons both in vitro and in vivo.

The Change of Detrusor Contractility at 5 Years After Transurethral Resection of the Prostate: A Single Center Prospective Observational Study.

Objective: To prospectively assess the impact of transurethral resection of the prostate (TURP) on detrusor function using pressure flow study (PFS) at 5 years after surgery in a single center prospective non-randomized observational study.

Methods: Sixty consecutive male patients were prospectively enrolled and underwent TURP from November 2014 to November 2018. A questionnaire survey, free uroflowmetry, and PFS were performed at baseline, and 6, 24, and 60 months after surgery.

Efficacy of Unsupervised YouTube Dance Exercise for Patients With Hypertension: Randomized Controlled Trial.

Background: High blood pressure (BP) is linked to unhealthy lifestyles, and its treatment includes medications and exercise therapy. Many previous studies have evaluated the effects of exercise on BP improvement; however, exercise requires securing a location, time, and staff, which can be challenging in clinical settings. The antihypertensive effects of dance exercise for patients with hypertension have already been verified, and it has been found that adherence and dropout rates are better compared to other forms of exercise.

A highly optimized and sensitive bowtie shape-based SPR biosensor for different analyte detection.

With advancements in photonic technologies, photonic crystal fibers (PCFs) have become crucial components in developing highly sensitive and efficient biosensors. This paper presents an optimized bowtie-shaped PCF biosensor that leverages surface plasmon resonance (SPR) phenomena for enhanced refractive index (RI) sensing. The proposed design uses an external sensing mechanism to effectively characterize performance across an RI range of 1.

Low-Gradient Severe Aortic Stenosis: Insights From the CURRENT AS Registry-2.

Background: Low-gradient (LG) aortic stenosis (AS) has not been fully characterized compared with high-gradient (HG) AS in terms of cardiac damage, frailty, aortic valve calcification, and clinical outcomes.

Objectives: The aim of this study was to compare the clinical characteristics and outcomes between each hemodynamic type of LG AS and HG AS.

Methods: The current study included 3,363 patients in the CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) Registry-2 after excluding patients without indexed stroke volume or left ventricular ejection fraction (LVEF) data.
