A study on the types of disaster awareness in nursing students: Q methodology.

Background: Research for the development of nursing education strategies to enhance the competency of the nursing students on disaster safety are needed. This study aimed to identify the types of perceptions on disaster safety in nursing students, and to analyze and describe the characteristics of each type of disaster safety perception of nursing students in South Korea.

Methods: An exploratory study design applying Q methodology, a research method designed to study subjectivity.

Prediction model of quality of life using the decision tree model in older adult single-person households: a secondary data analysis.

Background: Attention is drawn to the subjective health status and quality of life of older adult single-person households, whose number is gradually increasing as factors including low fertility, increased life expectancy, aging, and household miniaturization interact.

Objective: The study was to identify predictors that affect the quality of life of single-person households aged 65 years or older and living in South Korea.

Methods: A secondary data analysis design was used.

Fermented Ameliorates Depression-like Behavior in Sleep-Deprivation-Induced Stress Model.

Excessive stress plays a critical role in the pathogenesis of mood disorders such as depression. Fermented natural products have recently attracted attention because of their health benefits. We evaluated the antidepressant-like efficacy of fermented (FPF), and its underlying mechanisms, in sleep deprivation (SD)-induced stress mice.

Luteolin-7--Glucuronide Improves Depression-like and Stress Coping Behaviors in Sleep Deprivation Stress Model by Activation of the BDNF Signaling.

Stress exposure is a major risk factor for mental disorders such as depression. Because of the limitations of classical antidepressants such as side effects, low efficacy, and difficulty in long-term use, new natural medicines and bioactive molecules from plants with greater safety and efficacy have recently attracted attention. Luteolin-7--glucuronide (L7Gn), a bioactive molecule present in , is known to alleviate severe inflammatory responses and oxidative stress in macrophages.

Effects of Natural Polyphenols on Oxidative Stress-Mediated Blood-Brain Barrier Dysfunction.

The blood-brain barrier (BBB), which consists mainly of brain microvascular endothelial cells and astrocytes connected by tight junctions (TJs) and adhesion molecules (AMs), maintains the homeostatic balance between brain parenchyma and extracellular fluid. Accumulating evidence shows that BBB dysfunction is a common feature of neurodegenerative diseases, including stroke, traumatic brain injury, and Alzheimer's disease. Among the various pathological pathways of BBB dysfunction, reactive oxygen species (ROS) are known to play a key role in inducing BBB disruption mediated via TJ modification, AM induction, cytoskeletal reorganization, and matrix metalloproteinase activation.

sp. nov., isolated from soil.

Designated strain K5 was isolated from soil on Jeju Island. The bacterium was aerobic, Gram-stain-negative, oxidase-positive, catalase-low activity, motile, short-rod shaped, opaque and formed white colonies that were circular, raised and had entire margins. Strain K5 was able to grow at 15-40 °C, pH 4-9 and at 0-2 % (w/v) NaCl concentration.

Alloplastic total temporomandibular joint replacement using stock prosthesis: a one-year follow-up report of two cases.

Alloplastic total replacement of the temporomandibular joint (TMJ) was developed in recent decades. In some conditions, previous studies suggested the rationale behind alloplastic TMJ replacement rather than reconstruction with autogenous grafts. Currently, three prosthetic products are available and approved by the US Food and Drug Administration.
