Association between Alcohol Drinking Status and Depressive Symptoms in Korean Adults.

We investigated the association between alcohol drinking status and depressive symptoms in a representative sample of South Korean adults using data from the 2017 Korea Community Health Survey (KCHS), which included 216,771 participants (99,845 men and 116,926 women). Depression was defined as a Patient Health Questionnaire-9 score of ≥10. Multivariate logistic regression using sampling weights was used to assess the relationship between alcohol drinking status and depression after adjusting for potential confounders.

Screening for Atrial Fibrillation Using a Smartphone-Based Electrocardiogram in Korean Elderly.

Atrial fibrillation (AF) is responsible for 10-20% of cerebral infarctions. Several mobile devices have been developed to screen for AF and studies of AF screening have been conducted in several countries to evaluate the applicability of these mobile devices. In this tradition, we conducted a community-based AF screening using an automated single-lead electrocardiogram (SL-ECG).

Measurement of cooked rice stickiness with consideration of contact area in compression test.

The cooked rice stickiness is conventionally measured as the maximum detachment force required to separate the probe from the sample, after compression on the platform of a texture analyzer. A corrected stickiness (the measured stickiness force divided by the contact area) was newly created to avoid the deviation of stickiness influenced by the contact area varying with the rice sample's irregularity, regarding shape and size. The contact area could be estimated from the volume, density, and thickness of the samples.

Preliminary Study on Biosensor-Type Time-Temperature Integrator for Intelligent Food Packaging.

A glucose biosensor was utilized as a platform for the time-temperature integrator (TTI), a device for intelligent food packaging. The TTI system is composed of glucose oxidase, glucose, a pH indicator, and a three-electrode potentiostat, which produces an electrical signal as well as color development. The reaction kinetics of these response variables were analyzed under isothermal conditions.

The Association between Phase Angle of Bioelectrical Impedance Analysis and Survival Time in Advanced Cancer Patients: Preliminary Study.

Background: A frequent manifestation of advanced cancer patients is malnutrition, which is correlated with poor prognosis and high mortality. Bioelectrical impedance analysis (BIA) is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated BIA-derived phase angle as a prognostic indicator for survival in advanced cancer patients.

Association between the duration of palliative care service and survival in terminal cancer patients.

Purpose: Preliminary studies of early palliative care showed improved quality of life, less medical cost, and better survival time. But, most terminal cancer patients tend to be referred to palliative care late. For the proper care of terminal cancer patients, it is necessary to refer to hospice and palliative care timely.

Sasa borealis leaves extract improves insulin resistance by modulating inflammatory cytokine secretion in high fat diet-induced obese C57/BL6J mice.

Obesity is considered a mild inflammatory state, and the secretion of inflammation-related cytokines rises as adipose tissue expands. Inflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha), interlukin 6 (IL-6) and monocyte-chemoattractant protein 1 (MCP-1), are modulated by adipose tissue and known to play an important role in insulin resistance which is the common characteristics of obesity related disorders. In this study we analyzed the effects of Sasa borealis leaves extract on inflammatory cytokines and insulin resistance in diet induced obese C57/BL6J mice.

Ginsenoside Rh2 ameliorates scopolamine-induced learning deficit in mice.

To understand memory-enhancing effect of red ginseng biotransformed by Bifidobacterium longum H-1 (RGB), which more potently improved scopolamine-induced learning deficit than red ginseng in the preliminary experiment, its main constituents, ginsenosides Rb1, Rg3 and Rh2, were isolated and their memory-enhancing effects investigated in scopolamine-treated mice by using passive avoidance and Y-maze tests. Among them, ginsenoside Rh2 most potently reversed memory impairment caused by scopolamine. Ginsenoside Rh2 also significantly shortened the escape latencies prolonged by scopolamine in the Morris water maze test (p<0.

Magnolol and honokiol: inhibitors against mouse passive cutaneous anaphylaxis reaction and scratching behaviors.

The antiallergic effects of magnolol and honokiol, isolated from the bark of Magnolia obovata (family Magnoliaceae), were investigated both in vitro and in vivo. Magnolol and honokiol potently inhibited passive cutaneous anaphylaxis reactions in mice induced by IgE-antigen complex as well as compound 48/80-induced scratching behaviors. These constituents exhibited not only potent inhibitory activity on the degranulation of RBL-2H3 cells induced by IgE-antigen complex, with IC(50) values of 45 and 55 muM, respectively, but also inhibited the protein expressions of IL-4 and TNF-alpha.
