Antioxidant Defenses in the Brains of Bats during Hibernation.
Hibernation is a strategy used by some mammals to survive a cold winter. Small hibernating mammals, such as squirrels and hamsters, use species- and tissue-specific antioxidant defenses to cope with oxidative insults during hibernation. Little is known about antioxidant responses and their regulatory mechanisms in hibernating bats. We found that the total level of reactive oxygen species (ROS) ...
متن کاملMethylmercury neurotoxicity & antioxidant defenses.
Neurotoxicity induced by methylmercury (MeHg) increases the formation of reactive radicals and accelerates free radical reactions. This review summarizes recent findings in the MeHg-induced formation of free radicals and the role of oxidative stress in its neurotoxicity. Oxidative stress on CNS can produce damage by several interacting mechanisms, including mitochondrial damage with increase in...
متن کاملVesper
VESPER is a denotational formalism, that is, a collection of expressions each of which denotes some entity. Its logic, when viewed at the topmost level, is given by a single simpliication function. The simpliication is vertically extended in the sense that in a single act of simpliication an expression and (simultaneously) all or most of its subexpressions are recast into a simpler form. All VE...
متن کاملVariations in respiratory muscle activity during echolocation when stationary in three species of bat (Microchiroptera: Vespertilionidae).
Echolocating bats use respiratory muscles to power the production of biosonar vocalisations. The physical characteristics of these calls vary among species of bat, and variations also exist in the timing and patterns of respiratory muscle recruitment during echolocation. We recorded electromyograms from the respiratory muscles of three species of bat (Family Vespertilionidae) while the animals ...
متن کاملRenal adaptation during hibernation.
Hibernators periodically undergo profound physiological changes including dramatic reductions in metabolic, heart, and respiratory rates and core body temperature. This review discusses the effect of hypoperfusion and hypothermia observed during hibernation on glomerular filtration and renal plasma flow, as well as specific adaptations in renal architecture, vasculature, the renin-angiotensin s...
