Responsible but unprepared: experiences of newly educated nurses in hospital care.

The purpose of this study was to highlight the experience of being newly educated nurses working in internal medicine and surgical units. The nurses were asked to recount their initial work experiences using a narrative approach. A phenomenological hermeneutic method developed for life experience research was applied in the analyses.

Effects of high fat provision on muscle PDH activation and malonyl-CoA content in moderate exercise.

This study examined the effects of elevated free fatty acid (FFA) provision on the regulation of pyruvate dehydrogenase (PDH) activity and malonyl-CoA (M-CoA) content in human skeletal muscle during moderate-intensity exercise. Seven men rested for 30 min and cycled for 10 min at 40% and 10 min at 65% of maximal O(2) uptake while being infused with either Intralipid and heparin (Int) or saline (control). Muscle biopsies were taken at 0, 1 (rest-to-exercise transition), 10, and 20 min.

Skeletal muscle malonyl-CoA content at the onset of exercise at varying power outputs in humans.

To investigate the regulation of intramuscular fuel selection, we measured the malonyl-CoA (M-CoA) content in human skeletal muscle at three exercise power outputs [35, 65, and 90% maximal rate of O2 consumption (VO2 max)]. Four males and four females cycled for 10 min at one power output on three separate occasions with muscle biopsies sampled at rest and at 1 and 10 min. The respiratory exchange ratio was 0.

Effects of increased fat availability on fat-carbohydrate interaction during prolonged exercise in men.

The study examined the existence and regulation of fat-carbohydrate interaction during low- and moderate-intensity exercise. Eight males cycled for 10 min at 40% and 60 min at 65% maximal O2 uptake (VO2max) while infused with either Intralipid and heparin (Int) or saline (Con). Before exercise, plasma arterial free fatty acid (FFA) was 0.

Effect of oral creatine supplementation on muscle [PCr] and short-term maximum power output.

Our purpose was to determine the effect of creatine supplementation on power output during a 30-s maximal cycling (Wingate) test. Nine males underwent 3 randomly ordered tests following ingestion of a creatine supplementation (CRE), placebo (PLA), and control (CON) CRE was ingested as creatine monohydrate (CrH2O) dissolved in a flavored drink (20g.d-1 for 3 d), while PLA consisted of the drink only.
