Poor dietary behaviors among hospital nurses in Seoul, South Korea.

Background: Nurses reportedly practice unhealthy behaviors due to unfavorable work schedules. Korean nurses are particularly vulnerable to dietary and health behaviors due to high patient-to-nurse ratios; however, there are few studies on Korean hospital nurses' health behaviors.

Purpose: To investigate the dietary and health behaviors of Korean hospital nurses according to their work schedule type.

Activation of K(+) channel by 1-EBIO rescues the head and neck squamous cell carcinoma cells from Ca(2+) ionophore-induced cell death.

Ion channels in carcinoma and their roles in cell proliferation are drawing attention. Intracellular Ca(2+) ([Ca(2+)]i)-dependent signaling affects the fate of cancer cells. Here we investigate the role of Ca(2+)-activated K(+) channel (SK4) in head and neck squamous cell carcinoma cells (HNSCCs) of different cell lines; SNU-1076, OSC-19 and HN5.

Wall stretch and thromboxane A₂ activate NO synthase (eNOS) in pulmonary arterial smooth muscle cells via H₂O₂ and Akt-dependent phosphorylation.

Pulmonary arteries (PAs) have high compliance, buffering the wide ranges of blood flow. Here, we addressed a hypothesis that PA smooth muscle cells (PASMCs) express nitric oxide synthases (NOS) that might be activated by mechanical stress and vasoactive agonists. In the myograph study of endothelium-denuded rat PAs, NOS inhibition (L-NAME) induced strong contraction (96 % of 80 mM KCl-induced contraction (80K)) in the presence of 5 nM U46619 (thromboxane A2 (TXA2) analogue) with relatively high basal stretch (2.

Airway Smooth Muscle Sensitivity to Methacholine in Precision-Cut Lung Slices (PCLS) from Ovalbumin-induced Asthmatic Mice.

Asthma is a chronic inflammatory disease characterized by airway hyperresponsiveness (AHR) and reversible airway obstruction. Methacholine (MCh) is widely used in broncho-provocation test to evaluate airway resistance. For experimental investigation, ovalbumin-induced sensitization is frequently used in rodents (Ova-asthma).

Associations between state regulations, training length, perceived quality and job satisfaction among certified nursing assistants: cross-sectional secondary data analysis.

Background: In the U.S., there are federal requirements on how much training and annual continuing education a certified nursing assistant must complete in order to be certified.

Are nursing home survey deficiencies higher in facilities with greater staff turnover.

Objectives: To examine CNA and licensed nurse (RN+LPN/LVN) turnover in relation to numbers of deficiencies in nursing homes.

Design: A secondary data analysis of information from the National Nursing Home Survey (NNHS) and contemporaneous data from the Online Survey, Certification and Reporting (OSCAR) database. Data were linked by facility as the unit of analysis to determine the relationship of CNA and licensed nurse turnover on nursing home deficiencies.

[Development and validation of a tool for evaluating core competencies in nursing cancer patients on chemotherapy].

Purpose: This study was done to develop tool to evaluate the core competencies regarding nursing cancer patients on chemotherapy, and to verify the reliability and efficacy of the developed tool.

Methods: A tool to evaluate the core competencies was developed from a preliminary tool consisting of 112 items verified by expert groups. The adequacy of the preliminary tool was analyzed and refined to the final evaluation tool containing 76 items in 8 core competencies and 18 specific competencies.
