Canine copper toxicosis is an important inherited disease in Bedlington terriers, because of its high prevalence rate and similarity to human copper storage disease. It can lead to chronic liver disease and occasional haemolytic anaemia due to impaired copper excretion. The responsible gene for copper toxicosis in Bedlington terriers has been recently identified and was found not to be related to human Wilson's disease gene ATP7B. Although our understanding of copper metabolism in mammals has improved through genetic molecular technology, the diversity of gene mutation related to copper metabolism in animals will help identify the responsible genes for non-Wilsonian copper toxicoses in human. This review paper discusses our knowledge of normal copper metabolism and the pathogenesis, molecular genetics and current research into copper toxicosis in Bedlington terriers, other animals and humans.

OBJECTIVE - We examined the associations of physical activity with fasting plasma glucose (FPG) and with 2-h postload plasma glucose (2-h PG) in men and women with low, moderate, and high waist circumference. RESEARCH DESIGN AND METHODS - The Australian Diabetes, Obesity and Lifestyle (AusDiab) study provided data on a population-based cross-sectional sample of 4,108 men and 5,106 women aged >= 25 years without known diabetes or health conditions that could affect physical activity. FPG and 2-h PG were obtained from an oral glucose tolerance test. Self-reported physical activity level was defined according to the current public health guidelines as active (>= 150 min/week across five or more sessions) or inactive (< 150 min/week and/or less than five sessions). Sex-specific quintiles of physical activity time were used to ascertain dose response. RESULTS - Being physically active and total physical activity time were independently and negatively associated with 2-h PG. When physical activity level was considered within each waist circumference category, 2-h PG was significantly lower in active high-waist circumference women (beta-0.30 [95% CI -0.59 to -0.01], P = 0.044) and active low-waist circumference men(beta-0.25 [-0.49 to -0.02],P = 0.036) compared with their inactive counterparts. Considered across physical activity and waist circumference categories, 2-h PG levels were not significantly different between active moderate-waist circumference participants and active low-waist circumference participants. Associations between physical activity and FPG were nonsignificant. CONCLUSIONS - There are important differences between 2-h PG and FPG related to physical activity. It appears that 2-h PG is more sensitive to the beneficial effects of physical activity, and these benefits occur across the waist circumference spectrum.

The room temperature ionic liquid 1-n-butyl-3-methylimidazolium tetrafluoroborate (BMImBF4), is used as a `green` recyclable alternative to classical molecular solvents for the cyclocondensation of a-bromoketones with 2-aminopyridine to form 2-arylimidazo[1,2-a]pyridines with rate accelerations and improved yields.

The room temperature ionic liquid it-butylpyridinium tetrafluoroborate (BPyBF4) is used as a `green' recyclable alternative to classical molecular solvents for the cyclocondensation of alpha-tosyloxyketones with 2-aminopyridine. Significant rate enhancements and improved yields have been observed.
