Studies in insulin resistance following very low calorie diet and/or gastric bypass surgery.

The explanation for the rapid improvement in insulin resistance after Roux-en Y gastric bypass (RYGB) may involve mechanisms additional to caloric restriction and improvements in peripheral glucose disposal. 8 severely obese patients underwent a 6-day very low calorie diet (VLCD) (456 kcal/day) followed 1-3 weeks later by RYGB. Insulin resistance was measured by short intravenous insulin tolerance test (IVITT) and by homeostasis model assessment (HOMA) before and again 6 days after the VLCD and after RYGB.

The dyslexic student and mathematics in higher education.

Difficulties that are encountered by dyslexic undergraduates with their learning and understanding of mathematics are explored. Specific consideration is given to issues arising through mathematical content, its delivery, the procedures and processes of 'doing' mathematics, and its assessment. Particular difficulties, which have emerged through exploratory and explanatory multiple-case studies, and witnessed through the provision of one-to-one support to a dyslexic and dyspraxic engineering undergraduate, are detailed.
