Background: Weight gain and metabolic complications are substantial adverse effects associated with second-generation antipsychotics. However, comprehensive guidelines for managing antipsychotic-induced weight gain are lacking.

Methods: This review included all double-blind, placebo-controlled studies investigating metformin's effectiveness in addressing antipsychotic-related weight gain.

Taiwan harbors five endemic species of salamanders (Hynobius spp.) that inhabit distinct alpine regions, contributing to population fragmentation across isolated "sky islands". With an evolutionary history spanning multiple glacial-interglacial cycles, these species represent an exceptional paradigm for exploring biogeography and speciation.

The ingestion of Ti-containing nanoparticles from drinking water has emerged as a concern in recent years. This study therefore aimed to characterize Ti-containing nanoparticles in water samples collected from four water treatment plants in Taiwan and to explore the challenges associated with measuring them at low levels using single particle-inductively coupled plasma mass spectrometry. Additionally, the study sought to identify the most effective processes for the removal of Ti-containing nanoparticles.

Objective: To evaluate medication adherence among patients with hepatitis B-related cirrhosis who developed decompensation and mortality, and to examine the association between medication adherence and patients' disease outcomes.

Design: In this retrospective case-control study, patients aged over 20 years old and diagnosed with both chronic hepatitis B and cirrhosis from 2007 to 2016 are identified using a population-based medical claims database. Two prognosis endpoints (decompensation and mortality) are used, respectively, to classify subjects into two different case-control sets.

Background: Prolongation of the QT interval is associated with the risk of sudden infant death syndrome. QT interval differs depending on age at the time of screening. Screening protocols have yet to be established for Taiwanese patients.

The flavanoid hesperidin (Hsd) is one of the major polyphenols in citrus fruits. Hsd and its aglycone hesperetin (Hst) have a broad array of bioactivities; however, their low aqueous solubility and low intestinal permeability lead to their limited oral bioavailability. In the present study, we generated two water-soluble derivatives of Hst, namely, Hst 7--phosphate and Hst3'--phosphate, by a unique bioconversion process of var.

Article Synopsis
  • - The study examined how titanium dioxide nanoparticles (TiO NPs) are distributed in the Tamsuei River Basin, focusing on water samples from upstream, mid-stream, and downstream areas to analyze their mass concentration, number concentration, and size.
  • - Results showed that mass concentration of TiO NPs increased from upstream (1.04 μg/L) to downstream (31.7 μg/L), while the highest number concentration (479 NPs/mL) was also found downstream, indicating potential pollution from human activities.
  • - Surprisingly, mid-stream samples had the lowest number concentration of NPs (45.4 NPs/mL), likely due to the water preservation zone where particles can settle, and the particulate sizes

Article Synopsis
  • RTL has been traditionally used in East Asia for treating diabetes and shows promising phytochemical activities against nonalcoholic fatty liver disease (NAFLD).
  • The study tested RTL's aqueous and ethanolic extracts on diabetic rats induced by a high-fat diet and streptozotocin, showing that both extracts reduced liver and fat weights, as well as hepatic triglyceride levels.
  • The findings suggest that RTL could help manage NAFLD and reduce fat accumulation in the liver by regulating enzymes involved in de novo lipogenesis in these diabetic models.

is a selective agent that causes septic melioidosis and exhibits a broad range of lethal doses in animals. Host cellular virulence and phagocytic resistance are pathologic keys of . We first proposed as the host cellular virulence model to mimic bacterial virulence against mammals and second established the resistance of to predation by as the phagocytosis model.

Health-related physical fitness has decreased with age; this is od immense concern to adolescents. School-based health intervention programs can be classified as either population-wide or high-risk approach. Although the population-wide and risk-based approaches adopt different healthcare angles, they all need to focus resources on risk evaluation.
