13. AVALIAÇÃO DE INDICADORES DO ESTRESSE OXIDATIVO E DA ATIVIDADE DA ENZIMA ACETILCOLINESTERASE SANGÜÍNEA EM PACIENTES COM DIAGNÓSTICO DE ACIDENTE VASCULAR CEREBRAL ISQUÊMICO / AVALIATION OF MARKERS OF OXIDATIVE STRESS AND OF ENZYME ACETYLCHOLINESTERASE IN WHOLE BLOOD FROM PATIENTS DIAGNOSED WITH ISCHEMIC STROKE
In ischemic stroke, damage to the brain is caused by a reduction or complete blockage of blood flow to parts of the brain, resulting in glucose and oxygen deficiency. It is a leading cause of mortality and disability particularly in the elderly. The majority of strokes are not fatal and survivors are at a high risk of subsequent vascular complications and ne

14. Effects of water table management and nitrogen supplies in crops under hypoxia conditions in soil / Influência do manejo do nível freático e doses de nitrogênio em culturas sob hipoxia no solo
In many countries, extensive agricultural areas are affected by short-term waterlogging that cause significant damages to the crop yields. The objectives of this work were: a) to evaluate the stress effect of the soil water excess on lentil plants (Lens culinaris Medik) related to water table management; b) to evaluate the behavior of soybean cultivars (Glyc

15. ESTUDO EXPERIMENTAL DE COMPACTAÇÃO E EXPANSÃO DE UMA ESCÓRIA DE ACIARIA LD PARA USO EM PAVIMENTAÇÃO / EXPERIMENTAL EVALUATION OF COMPACTION AND EXPANSIBILITY OF THE STEEL SLAG FOR USE IN PAVEMENTS
The steel slag or BOF (Basic Oxygen Furnace) slag is a by-product generated in integrated steel plants. The use of this material in bases and sub-bases of pavements may present technical, economical and environmental advantages compared to natural aggregates. However, problems, like the expansibility and the deficiency of technical criteria for its acceptanc

17. Formation of soluble microbial products (SMP) in anaerobic reactors during stress conditions
Anaerobic wastewater treatment has many advantages over aerobic treatment, however, one factor that limits its application is the relatively high concentration of organic material in the effluent. Characterization of both aerobic and anaerobic effluents has shown that the majority of the residual chemical oxygen demand (COD) is due to soluble microbial produ

18. Analise dos alelos S e Z da alfa 1 antitripsina em uma amostra de pacientes fibrocisticos
Cystic fibrosis is a genetic disorder that during its course presents mainly pulmonary and pancreatic manifestations. Its genotype-phenotype correlation has motivated many arduous studies. The only correlation so far encountered is with pancreatic insufficiency. It has also been noted that the course of the disease as well as the severity of its pulmonary ma

19. Post-deposition cooling in oxygen is critical for YBa2Cu3O7-d films deposited by eclipse pulsed laser deposition method
YBa2Cu3O7-d thin films were deposited on MgO single crystals by means of an eclipse pulsed laser deposition method. Deposited films are cooled down in situ under an oxygen atmosphere at a given oxygen pressure. The relationship between critical temperature and oxygen deficiency was investigated by means of electrical resistance R(T)

20. Oxygen Deficiency Responsive Gene Expression in Chlamydomonas reinhardtii through a Copper-Sensing Signal Transduction Pathway1
Chlamydomonas reinhardtii activates Cpx1, Cyc6, and Crd1, encoding, respectively, coproporphyrinogen oxidase, cytochrome c6, and a novel di-iron enzyme when transferred to oxygen-deficient growth conditions. This response is physiologically relevant because C. reinhardtii experiences these growth conditions routinely, and furthermore, one of the target genes

21. Effects of Iron and Oxygen on Chlorophyll Biosynthesis 1: I. IN VIVO OBSERVATIONS ON IRON AND OXYGEN-DEFICIENT PLANTS
Corn (Zea mays, L.), bean (Phaseolus vulgaris L.), barley (Hordeum vulgare L.), spinach (Spinacia oleracea L.), and sugarbeet (Beta vulgaris L.) grown under iron deficiency, and Potamogeton pectinatus L, and Potamogeton nodosus Poir. grown under oxygen deficiency, contained less chlorophyll than the controls, but accumulated Mg-protoporphyrin IX and/or Mg-pr

22. Biochemical and Immunologic Analysis of Hereditary Myeloperoxidase Deficiency
Myeloperoxidase (MPO), a heme enzyme present in the azurophilic granules of human polymorphonuclear neutrophils (PMN), is important in the oxygen-dependent microbicidal activity of PMN. MPO deficiency, defined as the lack of PMN peroxidative activity, is a common genetic defect of human PMN. The purpose of our study was to characterize the structural basis f

23. Deficiency of skeletal muscle succinate dehydrogenase and aconitase. Pathophysiology of exercise in a novel human muscle oxidative defect.
We evaluated a 22-yr-old Swedish man with lifelong exercise intolerance marked by premature exertional muscle fatigue, dyspnea, and cardiac palpitations with superimposed episodes lasting days to weeks of increased muscle fatigability and weakness associated with painful muscle swelling and pigmenturia. Cycle exercise testing revealed low maximal oxygen upta

24. Formate Dehydrogenase, an Enzyme of Anaerobic Metabolism, Is Induced by Iron Deficiency in Barley Roots1
To identify the proteins induced by Fe deficiency, we have compared the proteins of Fe-sufficient and Fe-deficient barley (Hordeum vulgare L.) roots by two-dimensional polyacrylamide gel electrophoresis. Peptide sequence analysis of induced proteins revealed that formate dehydrogenase (FDH), adenine phosphoribosyltransferase, and the Ids3 gene product
