Oxygen consumption rate (OCR) is a reliable indicator of tissue health. Recently, the OCR of isolated human islets has been shown to predict transplant outcome in diabetic mice. The Oxygen Biosensor System (OBS) is a high-throughput, convenient assay that indirectly measures oxygen consumption by measuring oxygen partial pressure, pO2, adjacent to tissue loaded into the OBS multiwell plate. Solving the general species transport equations for a steady-state solution has not accurately converted pO₂ measurements to OCR. Furthermore, the time to reach steady-state is prohibitively long (at least 5 hr). Transient OBS experiments have been conducted and the rate of p02 change has been shown to correlate with the amount of viable tissue, however, no direct relation with OCR has been established. The overall objective of this thesis was to accurately measure OCR using transient OBS measurements. I fabricated flat OBS plates to simplify the geometry for theoretical models, but theoretical simulations did not match well with experimental data. Furthermore, fabricated flat OBS plates did not behave experimentally as would be expected from I-D, slab geometry. Simplified theoretical models were developed to qualitatively understand the effects of silicone rubber thickness, medium volume, and OCR density on the transient behavior of the OBS. It was shown that medium volume and OCR density should be increased as much as well-volume and tissue constraints allow. Commercial OBS plates were used for subsequent experiments, so it was unable to actively control silicone rubber thickness. Transient OBS measurements with both INS-1 cells and islets were correlated with stirred chamber OCR measurements conducted in parallel. The two measurements were linearly related and a calibration curve was developed so that OBS transient measurements could be converted to OCR. The relationship between the two measurements were similar enough for both cells and islets that the calibration curve seems to be independent of tissue geometry.
(cont.) Increased variability of islet tissue caused greater uncertainty about the islet prediction curve. This variability was compared with stirred chamber islet variability and islet sampling is hypothesized to be the underlying cause of high measurement variability with islets.

Full textNitrification is a prokaryote-mediated oxygen consumptive process of the oxidation of ammonia to nitrite/nitrate that traditionally has been only viewed as a nutrient transformation process. Renewed concern about hypoxia in the shallow hypolimnion of the Central Basin of Lake Erie provides impetus for examining whether nitrification has a significant impact on oxygen dynamics. To evaluate the contribution of nitrification to oxygen demand, water column and sediment samples were collected during the summers of 2008-2010 in Lake Erie and the oxygen consumption due to nitrification and the abundance and distribution of potential bacterial (AOB) and archaeal (AOA) that oxidize ammonia to nitrite was characterized in water column and sediment samples by qPCR of a portion of the ammonia monooxygenase (amoA) gene. Environmental variables and nitrification rates were examined for correlations to understand factors that may control nitrification rates and/or the distribution of nitrifiers. The nitrification rate in the epilimnion and hypolimnion was 3.1 ± 3.2 micromole N/L/day and 3.7 ± 2.9 (mean ± 1 SD) micromole oxygen/L/day respectively. Nitrification accounted for 28.2 ± 23.1% of the total oxygen consumption in the epilimnion and 32.6 ± 22.2% in the hypolimnion. Oxygen consumption by nitrification in sediment slurries and intact sediment cores was 7.1 ± 5.8 micromole oxygen/gram/day and 682 ± 61.1 micromole oxygen/square m/day respectively. Nitrification accounted for 27.0 ± 19.2% of the total oxygen consumption in sediment slurries and 30.4 ± 10.7% in intact sediment cores. AOA and AOB were present in all samples, with a distribution that was variable over time and space. Highlighting the potential importance of archaeal nitrifiers, the AOA/AOB ratio in the epilimnion, hypolimnion, and sediments was 1.02, 1.08, and 5.25. The nitrification rate or nitrifier numbers did not strongly correlate with environmental factors such as oxygen, nitrate or ammonium. In the water column, respiration and the percentage of oxygen used due to nitrification were negatively correlated. While nitrification is unlikely to be the dominant oxygen consumptive process, the rates observed in Lake Erie were sufficient to theoretically deplete a large portion of the hypolimnetic oxygen pool during the stratified period.

Full textDetta projekts målsättning var att använda accelerometerdata och KPI-värden för att prediktera syrekonsumtion för löpare på plan mark. Baserat på ett urval av studier om korrelationen mellan syrekonsumtion och löpekonomi samt en liten mängd data så konstruerades en modell med en förklaringsgrad på 81.1% på en individ. Svårigheter under arbetet inkluderar datajämförelser, icke-linjäriteter och databrus. Detta hanterades genom datatransformationer i mjukvaran R, modell-modifikationer och identifikation av avvikande data som kunde klassificeras som brus. Resultaten kan ses som en förstudie som indikerar att det är möjligt att prediktera syrekonsumtion genom accelerometerdata och KPI-värden. En fortsatt större studie med fler individer och mätningar som underlag kan validera denna slutsats samt då implementeras i Racefoxs nuvarande tjänst som en kalibreringsmetod för individuella resultat och som ett varningssystem för att undvika försämrad löpekonomi.
