Increased Urinary _L-Histidine Concentrations in Children with Obesity

Abstract

L-histidine plays an important role in the growth of infants and young children as well as positively improves insulin resistance through suppressed inflammation. The study aimed to investigate the relationship between L-histidine levels and obesity and evaluate the feasibility of L-histidine as an important indicator of auxiliary diagnosis for pediatric obesity. Thus, the urinary content of L-histidine from 74 children with obesity and 84 normal weight were determined and analyzed in the study. Results found that the L-histidine concentration in urine (median [interquartile range] mg/L) was 8.29 (4.42-20.70) mg/L in the children with obesity and 5.60 (2.16-14.06) mg/L in the normal-weight children (P<0.01), 5.71 (2.57-17.15) mg/L in girls and 9.92 (5.54-23.33) mg/L in boys (P<0.05). L-histidine concentration in severe obesity children were significantly higher than that of mild obesity (P<0.05). The urinary L-histidine levels were positively correlate with BMI and the mean and median of L-histidine concentration in urine increase with children's obese levels.

Summary of research on operation control of electrochemical energy storage power plants for offshore wind power

“…The results show that the system can accurately detect the small vibration deformation of the offshore wind turbine, and quickly generate the complete time series deformation image of the target, which confirms the excellent capability of GBIR technology in high-precision deformation monitoring. Xie L systematically studied and summarized the structural health monitoring system and operational safety assessment technology for offshore wind turbines [17]. It is pointed out that in the next 30 years, China's offshore wind industry will continue to expand into the deep sea.…”
