The behavioral physiology of labroid fishes
… torpor, or hibernation, based on low oxygen consumption rates in winter, contributing to a large Q10 value of 8.5. It is thus established as one of the few marine species that is known to hibernate. Cunner withstood four months of starvation at 4°C. Glycogen, lipid, and protein in the …

Responses to salinity of color polymorphs in two populations of the sea star, Pisaster achraceus
… (22, 30, and 40 psu).</p> <p>Wet mass-specific oxygen consumption rates were not significantly affected by color, location, or salinity, and Dry mass-specific oxygen consumption rates showed no significant differences for main effects, but a three-way interaction was identified. Similarly, …

Biochemical Thermodynamic Modelling of Cellular Bioenergetics: A Quantitative Systems Pharmacology Approach
… directly with elevated levels of reactive oxygen species (ROS) and oxidative stress within the mitochondria. The underlying mechanisms of redox cycling is very difficult to elucidate, due to the fleeting existence of the radical species. However, assessment of such cellular bioenergetics …

Effects of Temperature on Winter Energetics of Female Indiana Bats (Myotis Sodalis)
… chambers at 9°, 7°, 5°, 3°, and 1°C to calculate oxygen consumption during torpor, and during arousals at 9°, 7°, 5°, and 3°C. Torpid metabolism was affected by temperature; particularly, torpor metabolism at 9°C was higher than at 7° or 5°C. Although metabolism for arousals was not different …

Aspects of the respiratory metabolism of juvenile rainbow trout (Oncorhynchus mykiss) at sustained swimming speeds
… detectable diurnal variation in the respiration rates of juvenile rainbow trout. Experiments investigating aerobic energy expenditure at sustained swimming speeds, through measurements of oxygen consumption rates, are described. Oxygen consumption was found to increase exponentially with …

Effects of zinc and mercury on the white shrimp, Penaeus setiferus
… of locomotor activity, mortality, and oxygen consumption. Four-day mortality results (the number or percentage dead) allowed reasonable conclusions concerning zinc and mercury toxicity, but other methods of expressing data yielded additional information. Expressing mortality (time to …

Energetic costs of toxicant metabolism in rainbow trout ( Oncorhynchus mykiss)
… Energy metabolism was measured as changes in oxygen consumption rates and changes in plasma glucose and triglyceride concentrations as well as liver glycogen. PCB-126 and BNF treatments resulted in significant changes in metabolic parameters. Treatments with RVT were inconclusive. Although …

The Effects of Seasonal Changes and Turbidity on Swimming Performance in White Crappie Pomoxis Annularis and Black Crappie Pomoxis Nigromaculatus.
… Both species displayed a significant increase in oxygen consumption in response to elevated turbidity. There were no differences in oxygen consumption rates between the two species within any of the four seasons or at the three levels of turbidity tested.

Utilization of mitochondrial and microsomal metabolism for the assessment of toxicity
… assay, the maximum percent increase over control oxygen consumption rates elicited by the quinones ranged from eight percent to 837 percent. The ability of the compounds to stimulate microsomal oxygen uptake reflects their capability to redox cycle and form reactive oxygen species. Experiments …

Circulations and water mass balances in the Brazil Basin
… and conservation equations for heat, salt and oxygen (in which a consumption sink term is allowed), are written in centered finite difference form with lateral steps of 2 degree latitude and longitude and 8 levels in the vertical. This system of equations with constraints of positive …

Ecophysiology of Hibernating Eastern Red Bats (Lasiurus Borealis)
… and 15°C. Metabolism during torpor (measured as oxygen consumption rates) was assessed at -5, 1, 5, 10 and 15°C. These data were evaluated for differences between gender and Ta. My data suggest that gender has no effect on torpor duration (P = 0.441) and torpor duration was negatively correlated …

Thermoenergetics of Indiana Bats
… success for hibernation (minimal metabolic rates) will contribute to conservation efforts of this endangered species. To determine the effects of microclimate on the hibernation of the Indiana bat, we quantified energy budgets of Indiana bats at several ambient temperatures to determine the …

An investigation of some aspects of the transition from ectothermic to endothermic metabolism in vertebrates
The standard metabolic rates (SMRs) of 19 lizard and a single crocodilian species were measured at 30 "C, and 14 lizards at 37 "C. The basal metabolic rates (BMRs) of 8 mammal ian species were also determined using similar techniques. Although the inter-specific exponent relating BMR to body mass …

Oxygen Generating Materials for Tissue Restoration and Regeneration
… these injuries would benefit from provision of oxygen in situations where the vascular supply is acutely or more chronically compromised. To this end, this work pursued the utilization of a novel class of oxygen generating biomaterials in influencing skeletal muscle physiology. The goal of this …

Effects of Ammonia, Salinity and Oxygen on the Growth and Energetics of the Grass Shrimp, <i>Palaemonetes pugio</i>
… combinations of ammonia, salinity and dissolved oxygen. Experiments were performed to determine the effects of multiple stresses on the growth and physiological processes of the shrimp. The experimental design also allowed an evaluation of the effectiveness of several techniques for determining …

Characterization of Mitochondrially Targeted T3SS2 Effectors in Vibrio parahaemolyticus
… in HeLa cells, it decreased mitochondrial oxygen consumption rates and inhibited yeast growth. This growth phenotype was exacerbated by forcing the cells to use mitochondrial respiration for energy production. Metabolic analysis of the yeast expressing VPA1328 showed increases in fumarate, …
