Ultrasound‐Triggered Nanocomposite “Lever” Hydrogels with a Full Repair System Accelerates Diabetic Foot Ulcer Repair

Advanced Science, EarlyView.
Ultrasound (US)‐treated nanocomposite ‘lever’ hydrogels reprogrammed wound reactive oxygen species (ROS) levels and promoted wound healing in infected diabetic foot ulcers. Abstract Diabetic foot ulcers (DFUs) are a complex mixture of neuropathy, peripheral arterial disease, and infection, where excessive reactive oxygen species (ROS) exacerbates ...

Single‐Cell Analysis Reveals that Vitamin C Inhibits Bone Metastasis of Renal Cancer via Cell Cycle Arrest and Microenvironment Remodeling

Advanced Science, EarlyView.
3D‐cultured renal cancer cells exhibit stem‐like phenotypes and are more efficient in generating bone metastases. Vitamin C treatment can suppress the development of bone metastasis. Single‐cell transcriptomic analysis reveals that vitamin C inhibits metastasis by inducing tumor cell cycle arrest, suppressing osteoclast differentiation, and reducing ...

A Human Engineered Heart Tissue‐Derived Lipotoxic Diabetic Cardiomyopathy Model Revealed Early Benefits of Empagliflozin

Advanced Science, EarlyView.
This study develops a human engineered heart tissue‐derived model of diabetic cardiomyopathy that accurately replicates the dynamic changes in the structural, contractile, and electrophysiological properties of the myocardium. Furthermore, this model is used to confirm the direct protective effects of empagliflozin on the heart through an SGLT2 off ...

Vitamin D Status in Lean and Obese Mexican American Children [PDF]

, 2012
Vitamin D deficiency is a worldwide problem amongst adolescents and adults, particularly in minority populations due to high skin melanin content. Melanin blocks the absorption of UVB photons, which limits natural vitamin D accumulation, requiring more ...

Delayed Transplantation of Neural Stem Cells Improves Initial Graft Survival after Stroke

Advanced Science, EarlyView.
Delayed transplantation of human iPSC‐derived neural progenitor cells (NPCs) enhances graft survival, proliferation, and axonal sprouting after stroke. Using bioluminescence imaging and histology in a mouse model of stroke, it is shown that NPC delivery at 7 days post‐stroke is more effective than acute transplantation, highlighting the importance of ...

Vitamin D : its role in the musculoskeletal system and beyond [PDF]

, 2017
Vitamin D deficiency has a high prevalence due to inadequate exposure to sunlight and its limited presence in foods. Vitamin D deficiency has well-known consequences on the musculoskeletal system, namely osteoporosis and frequent falls in the elderly, in

Organocatalytic C─O Bond Cleavage and Asymmetric Transformations via [1,3]‐Sigmatropic Rearrangement

Advanced Science, EarlyView.
A direct asymmetric strategy for fulfilling the functional group transfer by aryl ether cleavage and migration is developed, representing the first Brønsted base‐catalyzed asymmetric [1,3]‐sigmatropic rearrangement reaction. The resulting chiral benzofuran products generated through this strategy exhibit significant 3D‐dimensionality and demonstrate ...

Monitoring the Dynamics of Alzheimer's Disease Biomarkers and the APOE–Tau Axis via Human Cerebral Organoids with Immuno‐SERS

Advanced Science, EarlyView.
Noninvasive and sensitive detection of tau protein dynamics across developmental stages and APOE genotypes remain a challenge in Alzheimer's disease (AD) research. This study reveals the dynamics of tau secretion in label‐free manner using surface‐enhanced Raman spectroscopy (SERS) and human cerebral organoids (hCOs). This study provides novel insights
