Food-related media use and eating behavior in different food-related lifestyle groups of Korean adolescents in metropolitan areas.

Background/objectives: This study investigated the relationship between adolescent food-related lifestyles and food-related media use and eating behavior in Korea.

Subjects/methods: Participants were 392 Korean adolescents, ranging in age from 12 to 18, recruited via convenience sampling. They completed a self-report questionnaire survey consisting of questions about food-related lifestyle, food-related media use, food consumption behavior, food literacy, and nutrition quotient.

Exploring the Impact of Appetite Alteration on Self-Management and Malnutrition in Maintenance Hemodialysis Patients: A Mixed Methods Research Using the International Classification of Functioning, Disability and Health (ICF) Framework.

Hemodialysis (HD) patients face a common problem of malnutrition due to poor appetite. This study aims to verify the appetite alteration model for malnutrition in HD patients through quantitative data and the International Classification of Functioning, Disability, and Health (ICF) framework. This study uses the Mixed Method-Grounded Theory (MM-GT) method to explore various factors and processes affecting malnutrition in HD patients, create a suitable treatment model, and validate it systematically by combining qualitative and quantitative data and procedures.

Installing extra bicarbonate transporters in the cyanobacterium Synechocystis sp. PCC6803 enhances biomass production.

As a means to improve carbon uptake in the cyanobacterium Synechocystis sp. strain PCC6803, we engineered strains to contain additional inducible copies of the endogenous bicarbonate transporter BicA, an essential component of the CO2-concentrating mechanism in cyanobacteria. When cultured under atmospheric CO2 pressure, the strain expressing extra BicA transporters (BicA(+) strain) grew almost twice as fast and accumulated almost twice as much biomass as the control strain.
