A Single‐Molecule Pleuripotent Scaffold for Combinational Therapy of Alzheimer's Disease via Intranasal Administration

open access: yesAdvanced Science, EarlyView.
Herein, guanidinium‐modified calix[5]arene (GC5AY) is developed featuring small size, positive charge, and desirable amphiphilicity, that can efficiently traverse the nasal mucosal barrier for brain drug delivery. Additionally, possessing inherent therapeutic functions, GC5AY can thus serve as a single‐molecule pleuripotent scaffold for multi‐target ...

Enhanced Selenium Supplement Extends Lifespan and Delays Multi‐Organs Aging by Regulating the Sik1 Pathway Through Maintaining Calcium Homeostasis

open access: yesAdvanced Science, EarlyView.
Aging involves physiological decline and heightened disease susceptibility, necessitating effective interventions. Redox‐responsive selenium‐loaded nanoparticles (SeMSNs) are developed, which delay cellular senescence by reducing oxidative stress and senescence markers (p16/p21). In aged mice, SeMSNs extend lifespan, improve organ function, and restore

Smoking‐Induced STC2+ Tumor Cells Drive Tumor‐Vascular Crosstalk in Laryngeal Squamous Cell Carcinoma via Spatial and Single‐Cell Transcriptomics

open access: yesAdvanced Science, EarlyView.
This study identifies a smoking‐induced mechanism in LSCC whereby nicotine activates the CHRNA5–JAK2/STAT3 axis to drive STC2 transcription. STC2 upregulates TGFBI, which interacts with endothelial ITGA5 to regulate vascular permeability and promote metastasis.

Systematic Review and Meta‐Analysis of Short‐ and Long‐Term Outcomes Following Natural Orifice Specimen Extraction for Colon Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Natural orifice specimen extraction (NOSE) in colon cancer surgery raises concerns about intra‐abdominal infection, peritoneal seeding, and local recurrence due to possible tumor cell implantation. This systematic review and meta‐analysis compares complete intracorporeal resection with NOSE versus conventional laparoscopic colon ...

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...
