Identification of Biomarkers Related to Metabolically Unhealthy Obesity in Korean Obese Adolescents: A Cross-Sectional Study.

Background: The current study aimed to screen for relationships and different potential metabolic biomarkers involved between metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) in adolescents.

Methods: The study included 148 obese adolescents aged between 14 and 16. The study participants were divided into MUO and MHO groups based on the age-specific adolescent metabolic syndrome (MetS) criteria of the International Diabetes Federation.

Metabolomic Signatures for the Effects of Weight Loss Interventions on Severe Obesity in Children and Adolescents.

Childhood obesity has increased worldwide, and many clinical and public interventions have attempted to reduce morbidity. We aimed to determine the metabolomic signatures associated with weight control interventions in children with obesity. Forty children from the "Intervention for Children and Adolescent Obesity via Activity and Nutrition (ICAAN)" cohort were selected according to intervention responses.

Changes in Plasma Choline and the Betaine-to-Choline Ratio in Response to 6-Month Lifestyle Intervention Are Associated with the Changes of Lipid Profiles and Intestinal Microbiota: The ICAAN Study.

Trimethylamine -oxide (TMAO) and its precursors, including choline, betaine, and L-carnitine, are gut microbiota-related metabolites associated with the risk of obesity. We aimed (1) to comprehensively examine whether the changes in plasma TMAO and its precursors induced by lifestyle intervention are associated with the improvements in plasma metabolic parameters; and (2) to identify the fecal microbiome profiles and nutrient intakes associated with these metabolites and metabolic index. Data from 40 participants (obese children and adolescents) having the plasma metabolites data related to the changes in BMI z-scores after 6-month lifestyle intervention were analyzed.

Film-thickness-driven superconductor to insulator transition in cuprate superconductors.

The superconductor-insulator transition induced by film thickness control is investigated for the optimally doped cuprate superconductor LaSrCuO. Epitaxial thin films are grown on an almost exactly matched substrate LaAlO (001). Despite the wide thickness range of 6 nm to 300 nm, all films are grown coherently without significant relaxation of the misfit strain.

Association between Physical Fitness and Cardiometabolic Risk of Children and Adolescents in Korea.

Background: This study aimed to investigate the association between physical fitness and cardiometabolic health of Korean children and adolescents.

Methods: In total, 168 participants (89 boys and 79 girls) aged 10-16 years were recruited for the Intervention for Childhood and Adolescent Obesity via Activity and Nutrition Study in 2016. The subjects were categorized into two groups using the definition of metabolic syndrome by the International Diabetes Federation: metabolically unhealthy (with at least two of the five criteria) and healthy groups (with less than one criterion).

Intake and blood concentrations of folate and their association with health-related behaviors in Korean college students.

The purpose of this study is to assess folate intake, and serum and red blood cell (RBC) folate concentrations, and investigate the association between folate status and health-related behaviors among Korean college students. A total of 169 students, aged between 18 and 27 years, participated in this study. Dietary intake data were collected by trained interviewers using a 24-hour recall method for three non-consecutive days in 2009.

Sphingobacterium composti sp. nov., isolated from cotton-waste composts.

A Gram-negative, strictly aerobic, short rod-shaped, non-motile bacterial strain designated 4M24(T) was isolated from cotton-waste compost. Analysis of the 16S rRNA gene sequence of strain 4M24(T) revealed that it is a member of the genus Sphingobacterium, sharing 88.5-94.
