Quantitative genetics and metabolomics of aerobic metabolism
… and physiological bases of variation in maximal aerobic metabolic rate (MMR) are important for understanding exercise physiology and the evolution of aerobic performance, but they still are not well understood. To this end, I studied three aspects of MMR. First, I estimated the genetic variances …

Oxyconformity in Burrow-dwelling Crustaceans : Aerobic Metabolism of HEMISQUILLA ENSIGERA CALIFORNIENSIS
… crustaceans in general, they have only limited anaerobic capabilities. Contrary to expectations, I found that <em>H. ensigera</em> is an oxyconformer or at best a weak oxyregulator, and that the species has substantial anaerobic capacity. Since it was able to survive at least 52 hours of anoxia, …

The Aerobic Metabolism and Behavior of the Burrow-dwelling Mantis Shrimp, HEMISQUILLA ENSIGERA CALIFORNIENSIS
… species is a near complete oxyconformer, so aerobic metabolism is strongly depressed at low oxygen levels, yet the animals remained active within the burrow even under these conditions. H. ensigera builds a blindended burrow that would be difficult to aerate by pumping oxygenated water into …

The metabolic rate of Xenopus laevis: Interactional influences of development and short term hypoxia
… tissue demand for oxygen may be reflected in the aerobic metabolic rate (MO{dollar}\sb2{dollar}). This study focuses on how MO{dollar}\sb2{dollar} of the South African clawed frog (Xenopus laevis) is affected by short term hypoxia during development. MO{dollar}\sb2{dollar} of animals from …

Evolution Of Lactate Dehydrogenase Genes In Primates, With Special Consideration Of Nucleotide Organization In Mammalian Promoters
… lactate, and conversion to pyruvate for use in aerobic metabolism, are catalyzed, in part, by the tetrameric enzyme lactate dehydrogenase (LDH). The two primary LDH genes, LDHA and LDHB, confer different rates of substrate turnover to the LDH enzyme, and these rates lend to the argument that …

In the Zone: the Effects of Soil Pipes and Dunes on Hyporheic and Riparian Zone Hydraulics and Biogeochemistry
… code SEAM3D to simulate microbially-mediated aerobic metabolism of dissolved organic carbon and dissolved oxygen, the combined effects of dune translation and microbial growth and death were explored. Major findings include that neglecting microbial growth can lead to inaccurate modeling of …

The Effects of Temperature on the Physiology of PHATARIA UNIFASCIALIS : and its Implications for the Species' Distribution in the Gulf of California
… of LA result in reduced rates of activity and aerobic metabolism. This suggests that the lower temperatures of the Bay of LA may be in part directly responsible for the lower success there.</p>

The Surface Properties of the Mammalian Small Intestine: their role in the Absorption of Nutrients and their Variation in Health and Disease
… (ATP) produced intracellularly through aerobic metabolism, by mucosally located ATPase. The hydrogen ions of the microclimate are retained at the surface by the hydrated glycocalyx. Normal intracellular aerobic metabolism, adequate amount of glucose or other metabolisable substrates that …

Effects of oxygen on embryonic stem proliferation, energetics, and differentiation into cardiomyocytes
… effect during culture without LIF. Aerobic metabolism was used to generate approximately 60% of the energy required by undifferentiated mES cells at high pO2, but substantially smaller fractions when cells were oxygen starved. This shift from aerobic to anaerobic respiration occurred …

Engineering outer-membrane electron transfer proteins for modular biotic-abiotic interfacing with living cells
… transfer (EET) through MtrCAB supports anaerobic respiration by passing electrons to extracellular acceptors, while extracellular electron uptake (EEU) imports electrons from extracellular donors to support aerobic metabolism. In this thesis, I demonstrate that the C-terminus of MtrC can …

Spectroscopic Technologies and Computational Approaches for Real-Time Detection of FMN as Biomarker during Machine Perfusion
… or blood-based, with the aim of reactivating aerobic metabolism prior to transplantation and enabling the assessment of organ viability through the analysis of metabolites released into the perfusion fluid. This doctoral thesis focuses on the use of technologies for the real-time detection of …

The effects of augmentation of coarse particulate organic matter in hyporheic sediments
… quantity and quality of organic matter affects metabolism and nutrient retention in the hyporheic zone of a low-order Appalachian stream. We hypothesized that hyporheic metabolic rates should increase with organic matter additions because the biotic activity is limited by organic matter …

The effect of reactive oxygen species on aged skeletal muscle
… by radiation, but are also the byproducts of aerobic metabolism. ROS have been found to mediate various pathological conditions in a variety of tissues, to cause oxidative damage to DNA, proteins, and lipids with advancing age, and is presumably a major factor contributing to changes …

Applications of Mass Spectrometry to Analysis of Prodiginines, Bioactivated Methylenedianiline Intermediates, and Hypoxia Induced Changes in the Zebrafish Skeletal Muscle Proteome
… proteins involved in mitochondrial oxidative metabolism are down-regulated, whereas glycolytic enzymes are up-regulated to compensate for the loss of ATP synthesis in aerobic metabolism. The up-regulation of two spots identified as hemoglobin variants was also observed. These protein …

SENSITIVITY AND RESILIENCE OF CNIDARIAN EARLY LIFE PROCESSES TO ANTHROPOGENIC CLIMATE CHANGE
… that exposure to seawater hypoxia disturbed aerobic metabolism leading to disrupted growth, development (e.g., decreased settlement), and physiology (e.g., decreased larval swimming) in early life stages of N. vectensis and two reef-building corals, Galaxea fascicularis and Porites …

Effect of Oxygen-Limiting Tidal Conditions on Muscle Metabolism and Structure in the Giant Acorn Barnacle, Balanus nubilus
… on muscle cells. We investigated changes in metabolism and structure of <em>B. nubilus</em> muscle in response to: normoxic immersion, anoxic immersion, or air emersion, for acute (6h) or chronic (6h exposures twice daily for 2wks) time periods. Following exposure, we immediately measured …

Transport of Folic Acid and Related Compounds Across the Small Intestine
… transport mechanism had a limited dependence on aerobic metabolism. When the folic acid derivative 10-formylfolic acid was present in the incubation medium at a 10:1 molar ratio with labelled folic acid the tissue accumulation was significantly reduced though the serosal transfer was not …

Hummingbird Hovering Energetics and Flight Capacities Across Elevational Gradients

Metabolism and gene expression during diapause in athropods
… of diapause remains largely unexplained. Aerobic metabolism in diapause, Artemia franciscana, embryos is reduced up to 92 % compared with post-diapause embryos. Differences in isolated mitochondria are insufficient to account for respiratory depression because mitochondria in diapause …
