Saccharomyces cerevisiae sub-species diastaticus (S. diastaticus) is the main fungal cause of spoilage of carbonated fermented beverages in the brewing industry. Here, prevalence of S.

Approaches to learning in science: a longitudinal study.

Background: Longitudinal studies of students' approaches to learning in higher education can tell us much about the impact of the tertiary experience. More information about teaching and learning practices and how students respond to these may enable educators to better assist students to gain the maximum benefit from their tertiary studies.

Aims: The study set out: (i) to monitor the change in approaches to learning over a three-year period; (ii) to evaluate the relationship between student age, sex and university entry mode on students' approaches to learning; and (iii) to evaluate the predictive validity of the SPQ scales on one mode of learning outcome, that being annual GPA.

A proposed simple method for detection and measurement of antibodies to insulin in serum by use of Staphylococcus aureus containing protein A.

A method is proposed for using Staphylococcus aureus containing protein A for the detection and measurement of insulin antibodies in the sera of insulin-requiring diabetics.

Effects of human growth hormone on the secretion of rat growth hormone.

Human growth hormone (hGH) was administered to chronically cannulated male rats and its effect upon the physiological secretory patterns of rat growth hormone (rGH) and prolactin were observed. In comparison with injected control animals, a reduction in the size of spontaneous secretory bursts of rGH was apparent when hormone concentrations were compared 3-6 h after administration of hGH (136.27 +/- 27.
