Background/objectives: Unhealthy food choices among young adults are common globally, and the incidence of chronic diseases, such as obesity, is rising. Food literacy (FL) is important for improving and maintaining individual health in a rapidly changing food environment and can form the basis for following a sustainable diet. Therefore, it is essential to improve FL among young adults, particularly college students, who are in the formative years of their lifelong food habits.

Background/objectives: Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status.

Zaltoprofen is a nonsteroidal anti-inflammatory drug with poor oral bioavailability. S(+)-zaltoprofen (SZPF)-loaded nanostructured lipid carriers (NLCs) were prepared to enhance oral bioavailability. SZPF-loaded NLCs (NLC-SZPF) were prepared using the hot-melting homogenization method and optimized using the Box-Behnken design.

Article Synopsis
  • MSNs (mesoporous silica nanoparticles) can cause adverse effects like hemolysis when used as anticancer drug carriers without modifications.
  • A new formulation, DOX@MSNs-man-g-PAA, enhances hemocompatibility and effectively targets cancer cells by utilizing mannose for improved drug uptake.
  • This coated nanoparticle shows sustained drug release, increases ROS levels and alters mitochondrial function in cancer cells, demonstrating strong tumor-suppressing effects in mice studies.

Article Synopsis
  • Ticagrelor (TCG) is a poorly soluble and permeable antiplatelet drug, leading to research on drug delivery improvements.
  • A high-loaded nanostructured lipid carrier (HL-NLC) for TCG was created, resulting in an optimized particle size and high encapsulation efficiency.
  • The final product, an S-HL-NLC tablet, showed significant improvement in bioavailability compared to raw TCG, with over 90% drug release in 24 hours and no cytotoxicity in tests.

Background: Food literacy (FL) is important as the ability to consider the unique aspects of food in our lives, society, and environment. The main objectives of this study were as follows: (1) to revisit the definition of FL, considering the cultural, relational, and ecological aspects that were often neglected in previous research, and (2) to develop a measurement tool for adults.

Methods: Expert workshops, the Delphi survey, the test-retest survey, and one-on-one interviews were conducted.

Objective: The aim of this study was to examine the associations of physical activity and body mass index (BMI) with the metabolic syndrome (MetS) in police officers.

Methods: Self-reported physical activity, MetS, and a modified MetS (MMetS, excluding obesity) were assessed in 448 officers.

Results: Of the officers, 27.

Background: Accelerometers can provide accurate estimates of moderate-to-vigorous physical activity (MVPA). However, one of the limitations of these instruments is the inability to capture light activity within an acceptable range of error. The purpose of the present study was to determine the validity of different activity monitors for estimating energy expenditure (EE) of light intensity, semi-structured activities.

Objective: To assess the association of sleep characteristics and mental health with the metabolic syndrome (MetS) in law enforcement officers (LEOs).

Methods: Sleep duration (≤6, >6-<8, ≥8 hours/night), sleep quality ("good," "poor"), mental health (stress, burnout, depression), and MetS components were compared in 106 LEOs.

Results: The prevalence of MetS was 33%.

Purpose: To assess the levels of stress and the prevalence of cardiovascular disease (CVD) risk factors in female law enforcement officers (LEOs).

Methods: Self-reported data including job-related stress and CVD risk factors were obtained from 65 female LEOs. Stress scores were compared with 429 males LEOs and CVD risk factors were compared with 1,213 demographically similar female respondents to the CDC BRFSS survey.
