Latitudinal differences in the hibernation characteristics of woodchucks (Marmota monax).
There is little information on the phenotypic flexibility of hibernation characteristics within species. To address this issue, we observed differences in hibernation characteristics of three free-ranging populations of woodchucks (Marmota monax) distributed along a latitudinal gradient from Maine to South Carolina. Data from free-ranging animals exhibited a direct relationship between latitude...
متن کاملEffects of corpora lutea removal and replacement with progesterone on pregnancy in goats.
p ROGESTERONE is predominantly a hormone of pregnancy and is required for (a) the growth and secretion of the glands in the uterine mucosa preparatory to implantation of the ovum (b) the nutrition and protection of the embryo during the time when it is lying free in the uterus (c) the development of the placenta and membranes after implantation (d) lobule-alveolar mammary growth (e) maintenance...
متن کاملProteomic mechanisms of cardioprotection during mammalian hibernation in woodchucks, Marmota monax.
Mammalian hibernation is a unique strategy for winter survival in response to limited food supply and harsh climate, which includes resistance to cardiac arrhythmias. We previously found that hibernating woodchucks (Marmota monax) exhibit natural resistance to Ca2+ overload-related cardiac dysfunction and nitric oxide (NO)-dependent vasodilation, which maintains myocardial blood flow during hib...
متن کاملElevated formation of nitrate and N-nitrosodimethylamine in woodchucks (Marmota monax) associated with chronic woodchuck hepatitis virus infection.
Nitrate balance and N-nitrosodimethylamine (NDMA) excretion were studied in woodchucks chronically infected with woodchuck hepatitis virus (WHV). Twenty-four-h urinary recovery of a bolus dose of [15N]nitrate was 54 +/- 12% in woodchucks. WHV-infected animals formed 3-fold more nitrate endogenously than did control animals (P less than 0.01). Treatment of WHV-infected animals with Escherichia c...
متن کاملElevated Formation of Nitrate and W-Nitrosodimethylamine in Woodchucks (Marmota monax) Associated with Chronic Woodchuck Hepatitis Virus Infection1
Nitrate balance and N-nitrosodimethylamine (NDMA) excretion were studied in woodchucks chronically infected with woodchuck hepatitis virus (WHY). Twenty-four-h urinary recovery of a bolus dose of |l5N]nitrate was 54 ±12% in woodchucks. VVHV-infectedanimals formed 3-fold more nitrate endogenously than did control animals (/' < 0.01). Treatment of WHV-infected animals with Escherìchiacoli lipop...
