Cholesteryl ester (CE) is an ester of cholesterol and fatty acid (FA). Plasma CE reflects complicated metabolisms of cholesterol, phospholipids, lipoproteins, and dietary FAs. An informatics approach could be useful for analysis of the CE species. In this study, two basic dimension reduction methods, principal component analysis (PCA) and factor analysis, were applied to serum CE species determined by LC-MS/MS in a Japanese population (n = 545). PCA and factor analysis both reflected the size (concentration), food source, fat solubility, and biological aspect of the CE species. In a comparison between PCA (PC4) and factor analysis (factor 4), the latter was found to be more suggestive from a biological aspect of n-6 FAs. Cholesteryl docosahexaenoate (DHA) was found to be unique by a factor analysis, possibly relevant to the unique accumulation of DHA in the brain. An informatics approach, especially factor analysis, might be useful for the analysis of complicated metabolism of CE species in the serum.

The widespread use of social media has led to growing concerns about its impact on mental health. As digital dependency rises, the Joy of Missing Out (JOMO) has emerged as a potential means to help individuals find satisfaction in offline activities and reduce social media addiction. This study examines the serial mediating role of loneliness and psychological distress in the relationship between JOMO and social media addiction while also validating the JOMO scale's psychometric properties.

Background: Coronary atherosclerosis is a leading cause of cardiovascular disease and death worldwide. Despite progress in understanding its pathogenesis, the roles of circulating inflammatory proteins and plasma metabolites are complex and not fully elucidated. Existing Mendelian randomization (MR) studies often target isolated biomarkers, lacking comprehensive and mechanistic insights.

Coronavirus, a large family of positive-sense RNA viruses, are responsible for both mild and severe respiratory illnesses, ranging from the common cold to life-threatening conditions. Despite significant advances in vaccine and antiviral development, the high mutability of human coronaviruses (HCoVs), such as SARS-CoV-2, presents a major challenge in treating these infections. Effective, broad-spectrum antiviral drugs are urgently needed to address both current and future HCoV outbreaks.

With the rapid development of the nuclear medicine business worldwide, the removal of iodine-131 from specific contaminated environments to protect public health has important application prospects. In this study, the surface decontamination mechanism of Ce(IV)/HNO3 as a decontaminant for iodine-131-contaminated nonmetallic materials was investigated by using an orthogonal experimental method and scanning electron microscopy (SEM). During the preparation experiments with the contaminated materials, both quartz glass and ceramics reached peak activity concentration levels at 4 h of adsorption (contamination) by using immersion; the decontamination factor (DF) was selected as the test index for the decontamination experiments.

Background: Malnutrition is a significant risk factor contributing to the progression of the elderly with pulmonary tuberculosis (TB). This study aimed to evaluate the nutritional status of the elderly with pulmonary TB using the Mini Nutritional Assessment (MNA) and explore the relationship between their nutritional status and physical function.
Methods: This was a cross-sectional survey study.
