1. Nitrogen source influences the antioxidative system of soybean plants under hypoxia and re-oxygenation
ABSTRACT: In this work, we compared nitrate-supplied plants (non-nodulated) with non-nitrate-supplied plants (nodulated) under oxygen privation of root system (hypoxia) and re-oxygenation (post-hypoxia; recovery) in order to verify whether N sources affect the antioxidant system during oxidative stress caused by hypoxia and post-hypoxia conditions. Antioxida

2. Techniques, Timing & Prognosis of Post Infarct Ventricular Septal Repair: a Re-look at Old Dogmas
Abstract Objective: The study aimed to identify the factors affecting the prognosis of post myocardial infarction (MI) ventricular septal rupture (VSR) and to develop a protocol for its management. Methods: This was a single center, retrospective-prospective study (2009-2014), involving 55 patients with post MI VSR. The strengths of association between ris

3. Neuroprotection of Persea major extract against oxygen and glucose deprivation in hippocampal slices involves increased glutamate uptake and modulation of A1 and A2A adenosine receptors
Ischemic stroke is characterised by a lack of oxygen and glucose in the brain, leading to excessive glutamate release and neuronal cell death. Adenosine is produced in response to ATP depletion and acts as an endogenous neuromodulator that reduces excitotoxicity. Persea major (Meins.) L.E. Kopp (Lauraceae) is a medical plant that is indigenous to South Brazi

4. Study of turbulent parameters and your relation with the coefficient reaeration with the use of the photographic technique / Estudo de parâmetros turbulentos e sua relação com o coeficiente de reaeração com o uso da técnica fotográfica
The importance given to the parameters of quality of the water, mainly in the last decades, it justifies the accomplishment of this work, that it investigates the relation of some turbulent parameters with the re-aeration coefficient, K IND.2 , through two different techniques of measure: the optic method and the photographic technique. The optic method rela

5. Origin of the Cytoplasmic pH Changes during Anaerobic Stress in Higher Plant Cells. Carbon-13 and Phosphorous-31 Nuclear Magnetic Resonance Studies
We tested the contribution of nucleoside triphosphate (NTP) hydrolysis, ethanol, and organic acid syntheses, and H+-pump ATPases activity in the acidosis of anoxic sycamore (Acer pseudoplatanus) plant cells. Culture cells were chosen to alter NTP pools and fermentation with specific nutrient media (phosphate [Pi]-deprived and adenine- or glycerol-suppli

6. HIF prolyl-hydroxylase 2 is the key oxygen sensor setting low steady-state levels of HIF-1α in normoxia
Hypoxia-inducible factor (HIF), a transcriptional complex conserved from Caenorhabditis elegans to vertebrates, plays a pivotal role in cellular adaptation to low oxygen availability. In normoxia, the HIF-α subunits are targeted for destruction by prolyl hydroxylation, a specific modification that provides recognition for the E3 ubiquitin ligase complex con

7. A Re-Evaluation of the Role of the Infected Cell in the Control of O2 Diffusion in Legume Nodules.
Two different simulation models were constructed to describe O2 diffusion into the bacteria-infected cells of legume nodules: one based on a central zone of uniform spherical cells and the other on a central zone of packed, uniform cubical cells with air spaces along the edges. The cubical model more closely approximated the geometry and gas diffusion charac

8. Regulated Phosphorylation of 40S Ribosomal Protein S6 in Root Tips of Maize1
Ribosomal protein S6 (RPS6) is located in the mRNA binding site of the 40S subunit of cytosolic ribosomes. Two maize (Zea mays) rps6 genes were identified that encode polypeptides (30 kD, 11.4 pI) with strong primary amino acid sequence and predicted secondary structure similarity to RPS6 of other eukaryotes. Maize RPS6 was analyzed by the use of two-di

9. The toxicity of benzene and its metabolism and molecular pathology in human risk assessment.
Benzene, a common industrial chemical and a component of gasoline, is radiomimetic and exposure may lead progressively to aplastic anaemia, leukaemia, and multiple myeloma. Although benzene has been shown to cause many types of genetic damage, it has consistently been classified as a non-mutagen in the Ames test, possibly because of the inadequacy of the S9
