Instructional Storytelling: Application of the Clinical Judgment Model in Nursing.

Background: Little is known about the teaching and learning implications of instructional storytelling (IST) in nursing education or its potential connection to nursing theory.

Method: The literature establishes storytelling as a powerful teaching-learning method in the educational, business, humanities, and health sectors, but little exploration exists that is specific to nursing.

Results: An example of a story demonstrating application of the domains of Tanner's clinical judgment model links storytelling with learning outcomes appropriate for the novice nursing student.

Sulfur amino acid deprivation in cadmium chloride toxicity in hepatoma cells.

The aim of this study was to investigate the effect of individual sulfur amino acid deprivation in cadmium chloride toxicity. HTC cells were deprived of cystine and/or methionine for 12h and then exposed to CdCl(2) for 12h. HepG2 cells were deprived of cystine for 3 and 5h and exposed to CdCl(2) for 3h.

Modulation of cadmium chloride toxicity by sulphur amino acids in hepatoma cells.

Cadmium is a toxic metal and no effective antidote exists at present. The aim of this study was to examine whether sulphur amino acids, involved in glutathione synthesis, can modulate cadmium toxicity in vitro. Two hepatoma cell lines (HepG2 and HTC cells) were exposed to cadmium chloride (0-100 microM) for 8h in control media or in media containing 1mM of homocysteine, cysteine or cystathionine.
