Relationships between Nursing Students' Skill Mastery, Test Anxiety, Self-Efficacy, and Facial Expressions: A Preliminary Observational Study.

Test anxiety and self-efficacy significantly influence the mastery of nursing skills. Facial expression recognition tools are central components to recognising these elements. This study investigated the frequent facial expressions conveyed by nursing students and examined the relationships between nursing skill mastery, test anxiety, self-efficacy, and facial expressions in a test-taking situation.

Ectoine Effect on Mechanical Properties of Vesicles in Aqueous Solution.

The mechanical properties of the vesicles incorporated with ectoine were studied using atomic force microscope (AFM). The vesicles were prepared with dipalmitoylphosphatidylcholine (DPPC) by changing only the ratio of the ectoine to DPPC. After the vesicles were adsorbed on the mica substrate and their morphology were characterized, the plot of an AFM tip displacement versus the tip deflection was acquired by monitoring the behavior of the tip into the vesicle.

Acetylcholine Detection Based on pH-Sensitive Liposomes.

The pH-sensitive liposomes were employed to amplify the detection of acetylcholine (ACh). Acetylcholinesterase (AChE) covalently immobilized on the magnetic particles and the pH-sensitive liposomes encapsulating ferricyanide were added to a cyclic voltammetry cell solution where ACh was distributed. The conversion of ACh into acetic acid seemed to induce the pH decrease that caused the reduction in the electrostatic repulsion between the head groups of weakly acidic 1,2-dipalmitoyl--glycero-3-succinate.

Effects of Attitude, Barriers/Facilitators, and Visual Differentiation on Oral Mucosa Pressure Ulcer Prevention Performance Intention.

Oral mucosa pressure ulcers (PUs) can result in frequent pain and discomfort, and have negative effects on quality of life. We aimed to examine attitude, barriers/facilitators of oral mucosa PU prevention, the ability to differentiate oral mucosa PU, and to identify factors influencing PU prevention performance intention. This was a cross-sectional descriptive study of 112 nurses in seven tertiary hospitals and three secondary hospitals.
