1. The thyroid hormone receptor β-selective agonist GC-1 does not affect tolerance to exercise in hypothyroid rats
Objective Investigate the effect of GC-1 on tolerance to exercise in rats with experimental hypothyroidism. Materials and methods Hypothyroidism was induced with methimazole sodium and perchlorate treatment. Six groups with eight animals were studied: control group (C), hypothyroid group without treatment (HYPO); hypothyroidism treated with physiological do

2. Solid polymer electrolytes based in sodium alginate. / Eletrólitos sólidos poliméricos a base de alginato de sódio
The aim of this study was the preparation and characterization of sodium alginate membranes plasticized with glycerol. The samples were obtained with different concentration of acetic acid or lithium perchlorate in order to use them as solid polymer electrolytes (SPE) in electrochemical devices, such as sensors and batteries. The films were characterized by

3. Levedura de cervejaria (Saccharomyces sp.) : composição, valor proteico e avaliação de toxicidade subcronica em celulas integras, celulas mecanicamente rompidas e concentrado proteico
The objective of this research was the study of brewer s yeast as an alternative source of nutrients in human foods. Suspensions (40% v/v) debittered yeast cells were macanically ruptured in Dynomill with 70% of its chamber filled with glass spheres (0.2 to 0.6 mm in diameter), 2,400rpm, feeding rate of 4.8 L/h and temperature of 15°C. Protein was extracted

4. Electrochemical study of tin/perchlorate and tin/perchlorate, citric acid interfaces / Estudo eletroquímico das interfases estanho/perclorato e estanho/perclorato, ácido cítrico
Realizaram-se estudos potenciostáticos e potenciodinâmicos do comportamento eletroquímico do estanho em meio ácido de perclorato de sódio desaerado, com adições sistemáticas de ácido cítrico. Paralelamente aos ensaios eletroquímicos acompanhou-se o estado superficial do eletrodo com microscópio de luz refletida e microscópio eletrônico de varre

5. Estudos cineticos da reação dos derivados benzila da cobaloxima com Hg (C104)2
In this work, the kinetics of the reactions of benzyl derivatives of cobaloxime and Hg(ClO4)2 in aqueous HClO4 vere investigated. The kinetic measurements were made under pseudo-first order conditions, with Hg(ClO4)2 always in excess. The study included eleven complexes, with the temperature constant at 25,0°C. The concentrations of cobaloxime, of mercury(I

6. Estudos potenciométricos sobre a formção de complexos entre índio (III) e azoteto, em meio aquoso / Potentiometric studies on the formation of indium (III) azide complexes in aqueous medium
The present study is a branch of the main work concerned with the complex formation between several metal cations and azide anion in aqueous media. Indium (III) was selected, in analogy to iron (III), because forms complexes with azide in aqueous media. Polarographic studies in development showed the tendency of these complexation. To determine the stability

7. Immunization Against Experimental Chagas' Disease by Using Culture Forms of Trypanosoma cruzi Killed with a Solution of Sodium Perchlorate
Protection against infection with virulent blood (trypomastigote) forms of Trypanosoma cruzi was accomplished in mice by immunization with culture (mainly epimastigote) forms killed by treatment with sodium perchlorate. Sodium chloride, used instead of sodium perchlorate, with all other conditions kept the same, failed to kill all the organisms, indicating t

8. NADPH-binding protein of the neutrophil superoxide-generating oxidase of guinea pigs.
Polymorphonuclear neutrophil membranes, activated in a cell-free system, contain all of the essential components required for superoxide formation including the NADPH-binding component. Arylazido-beta-alanyl- [32P]NADPH--3'-O-(3-[N-(4-azido-2-nitrophenyl)amino] propionyl)-[32P]NADPH--an NADPH analogue and photoaffinity probe, has been used to identify the sp

9. Ultrastructural Characterization of Genome of Epizootic Hemorrhagic Disease Virus
Purified epizootic hemorrhagic disease (EHD) virus preparations were treated with urea and sodium perchlorate. The viral ribonucleic acid (RNA) released when spread on protein monolayers according to the Kleinschmidt technique was examined by rotary shadow-casting electron microscopy. The viral RNA released by urea treatment had filaments which frequently fo

10. Alpha-helix in the carboxy-terminal domains of histones H1 and H5.
Although the carboxy-terminal domains of histones H1 and H5 exist as random-coil in aqueous solution, secondary structure prediction suggests that this region has a high potential for alpha-helix formation. We have measured CD spectra in various conditions known to stabilize alpha-helices, to determine whether this potential can be realized in an appropriate

11. Conformational transitions of alternating purine-pyrimidine DNAs in perchlorate ethanol solutions.
Conformational transitions of poly(dA-dC).poly(dG-dT), poly(dA-dT).poly(dA-dT), and other alternating purine-pyrimidine DNAs were studied in aqueous ethanol solutions containing molar concentrations of sodium perchlorate, which is a novel solvent stabilizing non-B duplexes of DNA. Using CD and UV absorption spectroscopies, we show that this solvent unstacks

12. RNA:DNA hybrids are more stable than DNA:DNA duplexes in concentrated perchlorate and trichloroacetate solutions.
Rates of formation of RNA:DNA hybrids have been measured as a function of temperature and compared to DNA:RNA duplex denaturation temperatures in 4 M sodium perchlorate, 4 M NaClO4-6 M urea, and 3 M rubidium trichloracetate solvents. The usual bell shaped curves of reaction rate versus temperature were observed. The optimal temperatures for the RNA:DNA assoc
