Interferometric, acousto-optic modulated diffuse correlation spectroscopy @ 1064 nm (AOM-iDCS) toward higher sensitivity, non-invasive measurement of cerebral blood flow
Continuous, bedside monitoring of cerebral blood flow in patients at risk for neurovascular complications has the potential to decrease morbidity and mortality. While measures of systemic physiology can be used to infer cerebral perfusion, a technology that directly and continuously measures …

Grape Seed Extract as an Adjunct for Modulating Colon Carcinogenesis
… vivo model of human colon cancer, azoxymethane (AOM) was used to induce pre-neoplastic colonic lesions in male Fischer 344 rats. These pre-neoplastic lesions are termed aberrant crypt foci (ACF). Both ACF and ACF with multiplicity (ACF with four or more aberrant crypts within a focus) are …

Methane cold seeps: Paleo proxies, modern measurements, and instrument development
… making the anaerobic oxidation of CH4 (AOM) a filter that prevents a significant fraction of dissolved CH4 from reaching the seawater. Despite its importance, our current constraints on AOM rates at marine cold seeps are very limited. Modern rate measurements are challenging and sparse, …

Acute Mastoiditis in Children – A National Study in Sweden
… to the use of antibiotics. Acute otitis media (AOM) is responsible for the highest number of antibiotic prescriptions to children although it is in most cases a self-limiting disease. Nevertheless, complications do occur in some case and the most common complication is acute mastoiditis (AM). …

Dietary Protein Concentration and the Metabolism of 1,2-Dimethylhydrazine by Mice
… ranging from 2.5 to 10 mM, DMH and azoxymethane (AOM) did not increase the mutation frequency of Salmonella typhimurium (Strain G-46) in vitro. Murine liver microsomes and cofactors caused a 40-fold increase in mutation frequency with dimethylnitrosamine (DMN) but not with DMH or AOM in vitro. …

Assessing the Effect of “Time of Birth” on Nasopharyngeal Microbial Load in Infants
Acute otitis media (AOM) is one of the most common childhood infections and its pathogenesis involves complex interactions between bacteria and viruses. Bacteria and viruses contributing to the AOM are collectively known as otopathogens. The objective of the capstone is to assess the effect of …

Epigenetic modifications on WNT genes by dietary genistein during colon cancer development
… increased apoptosis. By using an azoxymethane (AOM)-induced rat colon cancer model, we examined the ability of genistein to modify the epigenetic structure of Wnt signaling genes, which have been shown to be closely involved in colon carcinogenesis. Male Sprague-Dawley rats were fed a control …

Coupled cycling of metals with nitrogen and carbon in marine sediments
… measure rates of anaerobic oxidation of methane (AOM) in cold seep sediments collected at Cascadia Margin. Four forms of oxidized manganese and four forms of oxidized iron were added to treatments in order to evaluate how these altered rates of AOM. In contrast to previous work, addition of metals …

Metabolismus und Biomineralisation in anaerob Methan-oxidierenden Lebensgemeinschaften
Die anaerobe Oxidation von Methan (AOM) ist als Schlüsselprozess des marinen Methankonsums bekannt. Nach phylogenetischen und metagenomischen Analysen wird der Prozess von Konsortien aus syntrophen Archaeen und Sulfat reduzierenden Bakterien katalysiert. In dieser Arbeit wird ein umfassenderer …

Molecular Mechanisms of American Ginseng For the Prevention and Treatment of Colitis and Colon Cancer Associated With Colitis
… colitis (Chapter IV). Using the azoxymethane (AOM)/dextran sulfate sodium (DSS) mouse model of UC, we show that AG can suppress colon cancer associated with colitis. To explore the molecular mechanisms of the anti-cancer effects of ginseng, we also carried out antibody array experiments, and …

Design and implementation of a fiber optic doppler optical coherence microscopy system for cochlear imaging
… is used, utilizing an acousto-optic modulator (AOM) based optical heterodyne system to generate a stationary interference carrier frequency. By referencing this interference signal against the AOM drive signals, measurements of motions with magnitude on the order of 10 pm are shown to be …

Die Glutathionperoxidase 2 : physiologische Funktion und Rolle in der Azoxymethan-induzierten Colonkanzerogenese
… Modell der sporadischen, durch Azoxymethan (AOM) induzierten, Colonkanzerogenese hat. Im WT kam es in präneoplastischen Läsionen häufig zu einer erhöhten GPx2-Expression im Vergleich zur normalen Darmmucosa. Eine derartige Steigerung der GPx2-Expression wurde auch in der humanen …
