Article Synopsis
- The study investigates how body mass index (BMI), age, and sex affect blood pressure in children aged 7-17 during COVID-19 in City N, China, aiming to help with hypertension prevention and screening.
- Data was collected from 11,433 students across 36 primary and secondary schools using a cross-sectional method, with analysis performed using SPSS to examine relationships between BMI, age, sex, and both systolic and diastolic blood pressure.
- Results indicate that BMI and blood pressure increase with age, showing significant differences between boys and girls; regression models revealed positive relationships between age, BMI, and blood pressure, while resting heart rate correlated negatively with systolic blood pressure.*
Background: Existing evidence on the association between sedentary behavior (SB) and cognitive function remains inconclusive. Therefore, this study investigated the association between SB and the risk of cognitive decline (CD) or mild cognitive impairment (MCI) in the elderly.
Methods: A comprehensive search was independently conducted by two researchers (XC and GQ) in seven electronic databases, including Medline (via PubMed), China Biology Medicine, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang database, and VIP database for Chinese technical periodicals, covering studies published from the inception of database to June 2023.
A very efficient and environmentally benign method has been developed for the synthesis of 25-hydroxycholesterol. The reaction was performed in THF-water (4:1, v/v) using NBS as the brominating agent, followed by the easy reduction of C-Br with lithium aluminum hydride in THF, to yield the final product corresponding to a Markovnikov's rule. Excellent yields and regioselectivity have been obtained.
