Summary: Many compounds with the PUSC structure, including cinnamamide derivatives, have been found to effectively inhibit tyrosinase. The addition of a dithionate functional group to cinnamamide derivatives produces new compounds with high skin permeability and stronger inhibitory effects on tyrosinase. Kinetic studies and docking results confirm the mechanism of inhibition, and further research reveals the antioxidant and anti-melanogenic effects of these compounds. These findings provide a reference for the development of novel anti-melanogenesis agents.

Summary: Design and synthesis of (Z)-5-Benzylidene-2-phenylthiazol-4(5H)-one ((Z)-BPT) derivatives were conducted based on the structural characteristics of two tyrosinase inhibitors. Three derivatives (1-3) showed stronger tyrosinase inhibitory activities than kojic acid, and two of them exhibited potent anti-melanogenic effects. In addition, some derivatives also demonstrated remarkable antioxidant activities against various radicals. These findings suggest that (Z)-BPT derivatives 1 and 2 have promising potential as novel anti-melanogenic agents.

Summary: A series of cinnamide compounds linked with 1-aryl piperazines, derived from cinnamic acid derivatives, were synthesized and evaluated for their inhibitory activity against mushroom tyrosinase. The presence of a 3-chloro-4-fluorophenyl moiety at the N-1 position of the piperazine ring was found to be essential for a potent inhibitory effect. Molecular docking studies were conducted to investigate the interactions between the compounds and the active site of the enzyme. Some of the highly active compounds also showed potential in inhibiting melanogenesis. However, certain compounds exhibited toxicity at high concentrations.

Summary: This paper analyzes the substitution of P2P accommodation for traditional accommodation and the impact of the COVID-19 pandemic on demand and substitution effects, considering dynamic and spatial spillover effects. The results show that there is a significant substitution effect between P2P accommodation and hotels in the short term, and this substitution effect and consumer sensitivity to prices and substitution increase in the long term. However, the outbreak of COVID-19 has largely distorted the price and income elasticities.

Summary: Multiplex ligation-dependent probe amplification (MLPA) is effective in identifying genetic structural variants in SERPINC1 in 5% of antithrombin deficiency (ATD) cases. However, MLPA has limitations in detecting intronic structural variants, and can produce imprecise and false-positive results for genetic defects affecting MLPA probes. Validation of MLPA results is encouraged based on our study.

Summary: Multiple sclerosis (MS) is an immune-mediated disease that targets the myelin sheath of CNS neurons, causing axon injury, neuronal death, and neurological progression. Men with MS exhibit greater cognitive impairment and disability accumulation compared to women. The neurological progression in males is associated with chronic immune activation, increased iron accumulation, white matter lesions, whole brain and grey matter atrophy, and axon loss. Sex differences in biology, including sex chromosome complement and sex hormones, contribute to these disparities.

Summary: The repair of genome and proteome damage caused by ionizing radiation, oxidizing agents, and aging is crucial for cellular homeostasis. This study investigates the relationship between resistance/response to ionizing radiation, cellular aging, and the mechanisms of response to oxidative stress, free radicals, reactive oxygen species (ROS), and antioxidant activity in yeast. The results identify several common processes, such as homologous recombination, non-homologous end joining, and base excision repair pathways, as essential for maintaining cellular homeostasis. The study also proposes common biomarkers for radiation resistance/response and aging, as well as for response to radiation and oxidative stress.

Summary: Most pregnant women do not meet the recommended intake of vitamins A and E. However, higher levels of these vitamins in maternal serum during mid-pregnancy are associated with a higher antioxidant status in both the mother and the newborn. Gestational diabetes mellitus is negatively associated with maternal serum vitamin A levels, but no association with oxidative stress parameters was found.
