Liver carbohydrate and lipid metabolism of insulin-deficient mice is altered by trans-10, cis-12 conjugated linoleic acid.
2009
Feeding mice the trans-10, cis-12 (t10c12) conjugated linoleic acid (CLA) isomer is associated with lipodystrophy, insulin resistance, hyperinsulinemia, and liver steatosis. It has been hypothesized that CLA-induced liver steatosis is the result of increased hepatic lipogenesis stimulated by high insulin levels. We studied the effects of a 12-d t10c12CLA treatment (1 g/100 g diet) on liver carbohydrate and lipid metabolism in control and streptozotocin (STZ)-injected mice. STZ mice were characterized by insulin deficiency, hypertriglyceridemia, and depletion of liver triglyceride and glycogen. Remarkably, feeding t10c12CLA to diabetic mice (STZ-CLA) normalized these variables. Reconstitutio…
Reproductive Physiology ofAedes(Aedimorphus)vexans(Diptera: Culicidae) in Relation to Flight Potential
2001
Total protein, lipid, and glycogen of Aedes vexans (Meigen) were related linearly to body size at eclosion. Starvation after emergence led to the determination of minimal irreducible amounts of protein, lipid, and glycogen and the availability of the teneral reserves, whereas access to sucrose revealed the potential for reserve synthesis. Glycogenesis and lipogenesis increased reserves approximately 10-fold the teneral value within 1 and 2 wk after emergence, respectively. Carbohydrate feeding was an essential behavior before blood feeding and oogenesis commenced. Female flight was tested on a flight mill. Maximal flights of 10-17 km in a single night occurred at 2 wk posteclosion and paral…
