Mucins are the macromolecular key components of mucus. On wet epithelia of mammals, mucin solutions and gels act as powerful biolubricants and reduce friction and wear by generating a sacrificial layer and establishing hydration lubrication. Yet the structure-function relationship of mucin adhesion and lubrication remains elusive.

Background: C-type lectin (CTL) plays an important act in parasite adhesion, host's cell invasion and immune escape. Our previous studies showed that recombinant Trichinella spiralis C-type lectin (rTsCTL) mediated larval invasion of enteral mucosal epithelium. The aim of this study was to investigate protective immunity produced by vaccination with rTsCTL and its effect on gut epithelial barrier function in a mouse model.

Chronic wounds have emerged as a tough clinical challenge. An improved understanding of wound healing mechanisms is paramount. Collagen XVII (COL17), a pivotal constituent of hemidesmosomes, holds considerable promise for regulating epidermal cell adhesion to the basement membrane, as well as for epidermal cell motility and self-renewal of epidermal stem cells.

Curr Atheroscler Rep
January 2025
Houston Methodist DeBakey Heart and Vascular Center, Houston, TX, USA.
Purpose Of Review: The exposome refers to the total environmental exposures a person encounters throughout life, and its relationship with human health is increasingly studied. This non-systematic review focuses on recent research investigating the effects of environmental factors-such as air pollution, noise, greenspace, neighborhood walkability, and metallic pollutants-on atherosclerosis, a major cause of cardiovascular disease.
Recent Findings: Studies show that long-term exposure to airborne particulate matter can impair endothelial function and elevate adhesion molecule levels, leading to vascular damage.
Evaluating Bone Fracture Healing in a Rabbit Model Using Doppler Imaging Modes, Shear Wave Elastography, X-Ray, and Dual-Energy X-Ray Absorptiometry.

January 2025
Jefferson College of Health Professions, Thomas Jefferson University, Philadelphia, Pennsylvania, USA.
Objective: This study investigated methods of evaluating the bone fracture healing process using superb microvascular imaging (SMI; two modes color SMI [cSMI] and monochromeSMI [mSMI]), and shear wave elastography (SWE), relative to X-ray, dual-energy X-ray absorptiometry (DXA), and platelet endothelial cell adhesion molecule 1 (PECAM-1) also know as cluster of differentiation 31 (CD-31) staining in a rabbit model.
Methods: This IACUC-approved study involved eight rabbits that underwent a bilateral fibula osteotomy and were followed for 7 or 21 days (Groups 1 and 2 with 4 rabbits in each). Ultrasound examinations using cSMI, mSMI, and SWE were performed on Days 0, 4, 7, 14, and 21 post-surgery.
