This study found that RCS-01 cell therapy for aged skin was well tolerated and associated with increased gene expression related to extracellular matrix homeostasis, suggesting potential skin improvement.

Cancer prevention has progressed with successful drugs and vaccines, but challenges remain in understanding genetic changes and improving strategies.

This review discusses the diverse applications of algae in non-energy sectors, including pharmaceuticals, food ingredients, pigments, and cosmetics, and reports no new experimental results.

Skin changes can indicate starvation and nutritional deficiencies in anorexia nervosa.

This review discusses various cancer prevention strategies, summarizing established successes like tamoxifen for breast cancer and mixed outcomes of preventive trials like finasteride for prostate cancer, and reports no new results.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

In this study, carotene injected into the skin was converted into vitamin A by sebaceous gland cells, where it was not normally detectable.

This study using Mendelian randomization found that higher levels of circulating β-carotene and α-tocopherol may reduce the risk of androgenetic alopecia, while α-tocopherol may also protect against alopecia areata, suggesting diet-derived antioxidants could aid in preventing non-scarring alopecia.

This study observed that high-dose retinol palmitate was well-tolerated in resected stage I lung cancer patients, though it raised concerns about potential impacts on lipid metabolism due to elevated gamma-GT levels and triglycerides.
