Clinical efficacy of OS-01 peptide formulation in reducing the signs of periorbital skin aging.

Background: The aging of the skin, particularly around the periorbital region, is a complex process characterized by the accumulation of senescent cells, decreased collagen production, and reduced skin elasticity, leading to visible signs such as fine lines, wrinkles, and sagging.

Objective: This study investigates the efficacy of a novel topical formulation, OS-01 EYE, containing the senomorphic peptide, OS-01, along with other active ingredients, in improving the skin around the eyes.

Methods: A 12-week clinical study was conducted with 22 participants who applied OS-01 EYE twice daily.

Biomarkers.

Background: Down syndrome (DS, trisomy 21) is the most frequent genetic cause of intellectual disability (ID), prevalent in approximately 1 in 900 live births (Loane et al., 2013). People with DS are at high risk to develop Alzheimer's disease dementia (AD) (Lott & Head, 2001).

Hypoxia-induced conversion of sensory Schwann cells into repair cells is regulated by HDAC8.

After a peripheral nerve injury, Schwann cells (SCs), the myelinating glia of the peripheral nervous system, convert into repair cells that foster axonal regrowth, and then remyelinate or re-ensheath regenerated axons, thereby ensuring functional recovery. The efficiency of this mechanism depends however on the time needed for axons to regrow. Here, we show that ablation of histone deacetylase 8 (HDAC8) in SCs accelerates the regrowth of sensory axons and sensory function recovery.

Think-Aloud Testing of a Companion App for Colonoscopy Exams: Usability Study.

Background: Colonoscopies, are vital for initial screening, follow-ups, surveillance of neoplasia, and assessing symptoms like rectal bleeding. Successful colonoscopies require thorough colon preparation, but up to 25% fail due to poor preparation. This can lead to longer procedures, repeat colonoscopies, inconvenience, poorer health outcomes, and higher costs.

Quality and impact of youtube for patient education on prostatic artery embolization.

Purpose: To evaluate the quality of YouTube videos on patient education concerning prostatic artery embolization (PAE).

Methods: All PAE videos on YouTube were evaluated in December 2023. The quality of the videos was evaluated utilizing the DISCERN Scale Criterion.
