Toward low-friction and high-adhesion solutions: Emerging strategies for nanofibrous scaffolds in articular cartilage engineering.

Aging, trauma, pathology, and poor natural tissue regeneration are the leading causes of osteoarthritis (OA), an articular cartilage disease. Electrospun scaffolds have gained attention as potential matrices for the treatment of OA because of their high degree of ECM mimicry, which suits chondrocyte migration, adhesion, and proliferation. However, none of the products recently introduced in the market are nanofiber-based.

Design of solid lipid nanoparticles for skin photoprotection through the topical delivery of caffeic acid-phthalimide.

Exposure of the skin to ultraviolet (UV) radiation is associated with many pathological conditions such as premature aging and skin cancer. Furthermore, members of Nicotinamide Adenine Dinucleotide Phosphate-oxidase (NADPH oxidase or NOX) enzyme family can produce UV-induced reactive oxygen species (ROS), even after cessation of radiation exposure. The caffeic acid-phthalimide (CF) compound is a potent antioxidant, which reduces the generation of ROS.
