Post-Graduate Program in Pharmaceutical Sciences, State University of Maringá, Maringá, Paraná, Brazil. Electronic address:
Neglecting proper skin care and repeated exposure to ultraviolet (UV) radiation can have serious consequences, including skin burns, photoaging and even the development of skin cancer. UV radiation-induced damage is mediated by highly unstable and reactive molecules, named reactive oxygen species (ROS). To counteract ROS, the skin has an endogenous antioxidant system.

Department of Laboratory Medicine, The Third Xiangya Hospital, Central South University, Changsha, 410013, Hunan Province, China.
Purpose: infection is the most common pathogen in burn wound infections, causing delayed wound healing and progression to chronic wounds. Therefore, there is an urgent need to develop antimicrobial agents that can promote wound healing for effectively treating infected wounds.
Patients And Methods: Using magnetic stirring and ultrasound to synthesize Apt-pM@UCNPmSiO-Cur-CAZ.
Interplay of Light, Melatonin, and Circadian Genes in Skin Pigmentation Regulation.

Circadian regulation of skin pigmentation is essential for thermoregulation, ultraviolet (UV) protection, and synchronization of skin cell renewal. This regulation involves both cell-autonomous photic responses and non-cell-autonomous hormonal control, particularly through melatonin produced in a light-sensitive manner. Photosensitive opsins, cryptochromes, and melatonin regulate circadian rhythms in skin pigment cells.

Department of Microbiology, University of Helsinki, Helsinki, Finland.
Mycosporine-like amino acids are water-soluble secondary metabolites that protect photosynthetic microorganisms from ultraviolet radiation. Here, we present direct evidence for the production of these compounds in surface scums of cyanobacteria along the Baltic Sea coast. We collected 59 environmental samples from the southern coast of Finland during the summers of 2021 and 2022 and analysed them using high-resolution liquid chromatography-mass spectrometry.

State Key Laboratory of Pollution Control and Resource Reuse, College of Environmental Science and Engineering, Tongji University, Shanghai, 200092, PR China.
Background: The composition of anaerobically digested sludge is inherently complex, enriched with structurally complex organic compounds and nitrogenous constituents, which are refractory to biodegradation. These characteristics limit the subsequent rational utilization of resources from anaerobically digested sludge. White-rot fungi (WRF) have garnered significant research interest due to their exceptional capacity to degrade complex and recalcitrant organic pollutants.
