Background: Lifestyle modification (LM) is the mainstay in the management of obese children. This study aimed to investigate the long-term effects of a pediatric cohort participating in a hospital-based LM program.

Methods: Overweight/obese children and adolescents who visited a multidisciplinary LM program "The Health and Vitality Clinic" were included.

The process by which cells translate external mechanical cues into intracellular biochemical signals involves intricate mechanisms that remain unclear. In recent years, research into post-translational modifications (PTMs) has offered valuable insights into this field, spotlighting protein prenylation as a crucial mechanism in cellular mechanotransduction and various human diseases. Protein prenylation, which involves the covalent attachment of isoprenoid groups to specific substrate proteins, profoundly affects the functions of key mechanotransduction proteins such as Rho, Ras, and lamins.

Tyrosinase is a rate-limiting enzyme for melanogenesis and abnormal melanin production can be controlled by utilizing tyrosinase inhibitory substances. To develop potent and safe inhibitors of tyrosinase, complex tannins a narrowly distributed plant polyphenols were prepared from the fruit peel of Euryale ferox (EPTs) and then structurally characterized, as well as investigated for their inhibitory effects and the involved mechanisms against tyrosinase activity and melanogenesis. The structures of EPTs were established to consist of 63.

Parkinson's disease (PD), a neurodegenerative disorder without cure, is characterized by the pathological aggregation of α-synuclein (α-Syn) in Lewy bodies. Classic deposition pathway and condensation pathway contribute to α-Syn aggregation, and liquid-liquid phase separation is the driving force for condensate formation, which subsequently undergo liquid-solid phase separation to form toxic fibrils. Traditional Chinese Medicine (TCM) has a long history in treating neurodegenerative disease, herein; we identified chemicals from herbs that inhibit α-Syn aggregation.

Artificial neural networks (ANNs) can help camera-based remote photoplethysmography (rPPG) in measuring cardiac activity and physiological signals from facial videos, such as pulse wave, heart rate and respiration rate with better accuracy. However, most existing ANN-based methods require substantial computing resources, which poses challenges for effective deployment on mobile devices. Spiking neural networks (SNNs), on the other hand, hold immense potential for energy-efficient deep learning owing to their binary and event-driven architecture.
