The metabolic characteristics of type 2 diabetes, insulin resistance, and diminished insulin secretion are costly to measure directly. To evaluate the utility of several simple indices derived from insulin and glucose measurements, the indices were examined from 1982 to 1997 with respect to correlation with more sophisticated measures of insulin sensitivity(More)
BACKGROUND Early exposure to cow's milk has been implicated in the occurrence of insulin-dependent diabetes mellitus but there is little information about infant-feeding practices and subsequent non-insulin-dependent diabetes mellitus (NIDDM). We examined the association between breastfeeding and NIDDM in a population with a high prevalence of this(More)
Changes in serum insulin concentrations during deterioration of glucose tolerance were studied in 81 Pima Indians who worsened from normal to impaired glucose tolerance (IGT); 44 who changed from IGT to non-insulin-dependent diabetes mellitus (NIDDM); 27 who were seen at diagnosis of NIDDM and 1.4-8.5 years later; and 11 subjects who were seen at each of(More)
Concatenated sequence analysis with 16S rRNA, rpoB and fusA genes identified a bacterial strain (IRBG74) isolated from root nodules of the aquatic legume Sesbania cannabina as a close relative of the plant pathogen Rhizobium radiobacter (syn. Agrobacterium tumefaciens). However, DNA:DNA hybridization with R. radiobacter, R. rubi, R. vitis and R. huautlense(More)
AIM The efficacy and safety of insulin aspart (IAsp), a rapid-acting human insulin analogue, were compared with regular human insulin (HI) as the bolus component of basal-bolus therapy for subjects with gestational diabetes mellitus (GDM). METHODS In a randomized, parallel-group, open-labelled trial, 27 women with GDM (age 30.7 +/- 6.3 years, HbA(1c) <(More)
The risks of microvascular complications over periods of 3 and 6 years in relation to baseline plasma glucose concentrations were estimated in Pima Indians of Arizona aged 25 years or more and who were not taking hypoglycaemic medicine at their initial examinations. Retinopathy (microaneurysms, haemorrhages, or neovascularisation) developed within 3 years(More)
