The reported geographical association between Alzheimer's disease and levels of aluminium (Al) in water supplies may reflect the inverse relation between Al and silicon (Si) concentrations in water, and the potential for Si to reduce the bioavailability of the metal. We tested this hypothesis using isotopic 26Al tracer administered orally to five healthy… (More)
Individuals with Down's Syndrome (DS) develop the neuropathological features of senile dementia of the Alzheimer's type (SDAT) by early middle age. Because of recent evidence that gastrointestinal (GI) aluminum (Al) absorption is increased in patients with SDAT, and that Al may contribute to associated neuropathological changes, we have investigated the GI… (More)
Thin sections of deep-frozen unfixed muscle were studied in a scanning electron microscope modified for transmission imaging and equipped with a "cryostage" for vacuum compatibility of hydrated tissue. With an energy-dispersive x-ray analysis system, intracellular atomic species in the scan beam path were identified by their fluorescent x-rays and spatially… (More)
There is currently a lack of valid instruments to measure adolescent diabetes numeracy. The Diabetes Numeracy Test (DNT) was adapted for type 1 diabetes and was administered to 2 samples of adolescents. Sample 1 was administered the 39-item version of the DNT (DNT-39) with measures of self-management, responsibility, reading, and glycemic control (A1C).… (More)
Aluminium uptake from blood into tissues of control and homozygous hypotransferrinaemic (hpx/hpx) mice, following continuous intravenous infusion of 26Al and 67Ga, has been compared with that of gallium, a proposed tracer for aluminium. 26Al uptake into tissues of control (hpx/+ and +/+) mice occurred in the order (expressed as a space): bone 464.7 ml 100… (More)
Retinoids and rexinoids are prescribed for conditions ranging from acne vulgaris to hyperkeratosis to cutaneous T cell lymphoma. Dyslipidemia is a frequent consequence of the use of these drugs, with more than one-third of patients manifesting aberrations in triglyceride (TG) levels. The efficacy of retinoic acid derivatives is linked to their influence on… (More)
Thyroglossal duct cysts can contain ectopic thyroid tissue, and in some cases this tissue may be the only functional thyroid gland. We present the case of a 6-year-old girl with delayed diagnosis of iatrogenic hypothyroidism that developed after excision of a thyroglossal duct cyst.
