Adipokines and adipocyte function in Clock mutant mice that retain melatonin rhythmicity.

Clock(δ19)+MEL mutant mice, which retain melatonin rhythmicity, but lack peripheral tissue rhythmicity have impaired glucose tolerance, but reduced plasma free fatty acids, increased plasma adiponectin, and improved insulin sensitivity. Here, we report their response to a high-fat diet and adipocyte rhythmicity and function. The diet increased epigonadal fat weight similarly (twofold) in both wild-type and Clock(δ19)+MEL mice.

Chronic phase shifts of the photoperiod throughout pregnancy programs glucose intolerance and insulin resistance in the rat.

Shift work during pregnancy is associated with an increased risk for preterm birth and low birth weight. However, the impact upon the long term health of the children is currently unknown. In this study, we used an animal model to determine the consequences of maternal shift work exposure on the health of the adult offspring.

Female reproductive tract abnormalities in European hares (Lepus europaeus) in Australia. philip.stott@adelaide.edu.au.

Populations of European hare (Lepus europaeus) are in decline in Europe, and populations in Australia remain at low densities. Populations are sensitive to size of the breeding stock, which is influenced by fertility in the females. From 1996 to 1999, a total of 272 adult female hares from three Australian populations were dissected and their reproductive systems examined for abnormalities.
