1. Investigação da enzima Bilirrubina oxidase como catalisador da reação de redução eletroquímica de oxigênio / Investigation of the enzyme Bilirubin Oxidase as a catalyst for the oxygen electrochemical reduction reaction
Bilirrubina oxidase de Myrothecium verrucaria é uma multicobre oxidase capaz de reduzir O2 pela oxidação de fenóis, aminas aromáticas e polipirróis. Eletroquimicamente, essa reação de redução ocorre pela transferência de elétrons entre a enzima e um eletrodo. Nesta tese, foi investigada a eficiência da enzima como agente redutor de O2 na superf�

2. Use of biomimetic systems at the preparation of amperometric sensors / Utilização de sistemas biomiméticos no Preparo de sensores amperométricos
This work describe the immobilization of the copper(II) dinuclear complex ([Cu2(apyhist)2Cl2](ClO4)2), (apyhist =[(4-imidazolyl)ethylene-2-amino-1-ethylpyridine]), and others similar copper(II) compounds mono- and tetranuclears, obtained in water solution or for desprotonation of the imidazole ligant, in the Nafion membrane on glass carbon electrode surface,

3. Intestinal Absorption of Hemoglobin Iron-Heme Cleavage by Mucosal Heme Oxygenase
Hemoglobin and myoglobin are a major source of dietary iron in man. Heme, separated from these hemoproteins by intraluminal proteolysis, is absorbed intact by the intestinal mucosa. The absorbed heme is cleaved in the mucosal cell releasing inorganic iron. Although this mucosal heme-splitting activity initially was ascribed to xanthine oxidase, we investigat

4. Heme Oxygenase-2 Deletion Causes Endothelial Cell Activation Marked by Oxidative Stress, Inflammation, and Angiogenesis
In previous studies, we have shown that heme oxygenase (HO)-2 null [HO-2(−/−)] mice exhibit a faulty response to injury; chronic inflammation and massive neovascularization replaced resolution of inflammation and tissue repair. Endothelial cells play an active and essential role in the control of inflammation and the process of angiogenesis. We examined

5. Beneficial effects and improved survival in rodent models of septic shock with S-methylisothiourea sulfate, a potent and selective inhibitor of inducible nitric oxide synthase.
Enhanced formation of nitric oxide (NO) by both the constitutive and the inducible isoforms of NO synthase (NOS) has been implicated in the pathophysiology of a variety of diseases, including circulatory shock. Non-isoform-selective inhibition of NO formation, however, may lead to side effects by inhibiting the constitutive isoform of NOS and, thus, the vari
