Background: The use of disinfectants is crucial to preventing the spread of nosocomial infections in health care workers. As many as 25 applications of hand disinfectants is a realistic default value during a working day. However, alcohol-based hand disinfectants may weaken skin barrier function and induce dryness and eczema, which decrease their acceptance.
Objective: To evaluate the effect of ethanol-containing disinfectants with 5% urea on skin barrier function and on sensitivity to an irritant soap (sodium lauryl sulfate [SLS]).
Methods: Twenty healthy volunteers treated one of their forearms twice daily for 17 days with an ethanol-containing gel with 5% urea. Two types of gels with urea were tested. Treatment was randomized to left or right forearm, and the contralateral forearm served as untreated control. Transepidermal water loss, skin capacitance (dryness), and sensitivity to SLS were evaluated.
Results: Twice-daily application of the urea-containing ethanol gels lowered transepidermal water loss, prevented dryness, and reduced sensitivity to SLS compared with the untreated control skin.
Conclusions: Improved barrier function using this ethanol gel with urea may have relevance in daily disinfectant procedures.

Oxidative stress and neuronal apoptosis could be an important factor leading to post-hemorrhagic consequences after germinal matrix hemorrhage (GMH). Previously study have indicated that relaxin 2 receptor activation initiates anti-oxidative stress and anti-apoptosis in ischemia-reperfusion injury. However, whether relaxin 2 activation can attenuate oxidative stress and neuronal apoptosis after GMH remains unknown.

Background: The regenerative potential of mesenchymal stromal/stem cells (MSCs) has been extensively studied in clinical trials in the past decade. However, despite the promising regenerative properties documented in preclinical studies, for instance in osteoarthritis (OA), the therapeutic translation of these results in patients has not been fully conclusive. One factor contributing to this therapeutic barrier could be the presence of senescent cells in OA joints.

Spinal cord injury (SCI) is a critical condition affecting the central nervous system that often has permanent and debilitating consequences, including secondary injuries. Oxidative damage and inflammation are critical factors in secondary pathological processes. Selenium nanoparticles have demonstrated significant antioxidative and anti-inflammatory properties via a non-immunosuppressive pathway; however, their clinical application has been limited by their inadequate stability and functionality to cross the blood-spinal cord barrier (BSCB).

Cellular senescence contributes to inflammation and organ dysfunction during aging. While this process is generally characterized by irreversible cell cycle arrest, its morphological features and functional impacts vary in different cells from various organs. In this study, we examined the expression of multiple senescent markers in the lungs of young and aged humans and mice, as well as in mouse lung endothelial cells cultured with a senescence inducer, suberoylanilide hydroxamic acid (SAHA), or doxorubicin (DOXO).
