Abstract In this study, we aimed to separately evaluate the relationship between waist circumference and incidence of hyperuricemia in men women general Japanese population. We performed a population-based longitudinal study using data from annual health examination residents Iki City, Japan. A total 5567 participants without at baseline were included analysis. The placed into groups according tertile circumference. outcome was incident (uric acid > 416 µmol/L [7.0 mg/dL]). investigated...

It has been suggested that non-fasting triglyceride (TG) concentrations may be useful in predicting various diseases. However, current epidemiological evidence focuses mainly on the effects of fasting TG concentrations. The aim this study was to investigate effect and levels new-onset hyperuricemia (HUA) general Japanese population. This is a population-based retrospective cohort (ISSA-CKD study); it included 5,576 participants without HUA at baseline between 2008 2019. Participants were...

BACKGROUND: If it were possible to deduce the mechanism of injury in cryopreserved embryos by their appearance, would help optimize cryopreservation protocols. METHODS: Mouse blastocysts treated so that they damaged six types cryoinjuries listed below, and appearance was observed at recovery sucrose solution a modified phosphate-buffered saline (PB1), after culture for 1 24 h. RESULTS: (i) Intracellular ice: shrank normally solution, but swelled PB1 collapsed culture. (ii) Chemical toxicity...

Both body mass index (BMI) and waist circumference (WC) are associated with diabetes risk, the difference between them in predictive ability for is still contentious. We conducted a population-based study to investigate compare association of by sex. This included total 4754 subjects aged 40–80 years no at baseline 2008 2017. Using multivariate Cox proportional hazards models, we calculated hazard ratios according tertiles BMI or WC. Harrell's C statistics was applied assess models using WC...
