Research Progress on the Anti-skin Photoaging Mechanism of Oral Collagen Hydrolysate and Strategies for Promoting Its Absorption [PDF]

Shipin Kexue
Photoaging represents the primary exogenous contributor to skin aging, triggered by ultraviolet exposure. It compromises skin barrier integrity, disrupts elastic fibers, accelerates collagen breakdown, and intensifies oxidative stress.

Guided bone regeneration in long-bone defect with a bilayer mineralized collagen membrane

Collagen and Leather, 2023
Bone regeneration for large, critical-sized bone defects remains a clinical challenge nowadays. Guided bone regeneration (GBR) is a promising technique for the repair of multiple bone defects, which is widely used in oral and maxillofacial bone defects ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Collagenous Gastritis

International Journal of Surgical Pathology, 2008
A 25-year-old patient presented with epigastric pain, which on gastric biopsy revealed the characteristic appearance of collagenous gastritis. There was a thick prominent subepithelial band that was confirmed to be collagen with a Masson’s trichrome stain.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
