The interactions between the sun and the skin have both beneficial and harmful aspects. While the sun provides important positive effects, there are also serious harmful consequences to consider, particularly from ultraviolet radiation, commonly referred to as UV-A and UV-B. To mitigate these harmful effects, the topical application of sunscreens and the avoidance of extreme sun exposure are widely recognized as the most effective strategies to prevent sunburn and skin edema. Additionally, this approach can efficiently reduce the risk of developing skin cancer.The primary aim of sunscreen products is to minimize the damage caused by sun exposure while maintaining good...

Research Summary: This study investigated the effects of a skin protectant solution (dimethicone 2%) on clinical signs and skin barrier function in canine atopic dermatitis (AD). Eighteen dogs with AD were randomly divided into two groups, with one group receiving dimethicone and the other receiving the vehicle (cyclomethicone) on selected areas (pinnae, groin, and axillae) daily for 4 weeks. Owners and investigators were blinded to group allocation.Clinical efficacy was evaluated using a scoring system, and skin barrier function was assessed by measuring transepidermal water loss (TEWL). Twelve dogs completed the study, with a 50% drop rate in the vehicle group...

Research Summary: Retinoic acid (RA) is the biologically active metabolite of vitamin A. It is a low molecular weight, lipophilic molecule that acts on the nucleus to induce gene transcription. In amphibians and mammals, it induces the regeneration of several tissues and organs, and these examples are reviewed here. RA induces the "super-regeneration" of organs that can already regenerate, such as the urodele amphibian limb, by respecifying positional information in the limb. In organs that cannot normally regenerate, such as the adult mammalian lung, RA induces the complete regeneration of alveoli that have been destroyed by various noxious treatments. In...
