1. Losses through gases and effluent and nutritional value of Brachiaria decumbens with addition of soybean hulls
The objective of this experiment was to evaluate the losses of nutrient through gases and effluents, the nutrient recovery, fermentation parameters and the chemical parameters of silages of Brachiaria decumbens with the addition of soybean hulls, testing five levels of inclusion: 0, 10, 20, 30 and 40% (as is), with five replications per treatment. After the

2. Formas de potassio em regossolos do estado da Paraiba.
Este trabalho teve como objetivo determinar as formas de potassio em regossolos do Estado da Paraiba e correlaciona-las entre si. Os parametros analisados foram K trocavel, K nao-trocavel, K total, K extraido pelo Bray l, potencial de potassio e poder tampao de potassio (PTK). As formas de potassio mostraram-se altamente correlacionadas entre si. O potassio

3. Formas de potassio em solos do estado do parana e sua disponibilidade para as plantas em cultivos sucessivos / Forms of potassium in soils of the state of parana and their availability to plants in successive crops
A absorÃÃo de K pelas plantas, em geral, e maior que a quantidade inicial de K trocÃvel, indicando que formas nÃo-trocÃveis contribuem no suprimento deste nutriente as plantas. Assim, o presente trabalho teve como objetivos (a) determinar as formas de K total, K nÃo-trocÃvel, K trocÃvel e K na soluÃÃo do solo; (b) determinar o poder tampÃo de pot�

4. The effects of magnesium on potassium transport in ferret red cells.
1. The magnesium dependence of net and isotopic (using 86Rb as tracer) potassium transport was measured in fed ferret red cells. Bumetanide (0.1 mM) was used to dissect total flux into two components: bumetanide sensitive and bumetanide resistant. 2. Increasing the external magnesium concentration from zero (added) to 2 mM stimulated bumetanide-sensitive upt

5. Effect of buffers on testing of Candida species susceptibility to flucytosine.
Synthetic amino acid medium for fungi (SAAMF) is a totally defined, nutritionally adequate, macromolecule-free culture medium for fungi that is buffered with an organic weak acid-weak base pair: 2-(N-morpholino)-propanesulfonic acid (MOPS) and 2-amino-2-(hydroxymethyl)-1,3-propanediol (Tris). In 1984, it was reported that MOPS-Tris in SAAMF antagonized the a

6. Control of resting membrane potential by delayed rectifier potassium currents in ferret airway smooth muscle cells.
1. In order to determine the physiological role of specific potassium currents in airway smooth muscle, potassium currents were measured in freshly dissociated ferret trachealis cells using the nystatin-permeabilized, whole-cell method, at 35 degrees C. 2. The magnitude of the outward currents was markedly increased as bath temperature was increased from 22

7. The Effects of Cyanate In Vitro on Red Blood Cell Metabolism and Function in Sickle Cell Anemia
Cyanate, which is in equilibrium with urea, combines with the α-amino group of the aminoterminal valine of hemoglobin in an irreversible, specific carbamylation reaction. Partial carbamylation (0.72 residues/hemoglobin tetramer) as determined by cyanate-14C incorporation or hydantoin analysis diminishes the in vitro sickling phenomenon. Since cyanate may re

8. Calcium-activated potassium channels in native endothelial cells from rabbit aorta: conductance, Ca2+ sensitivity and block.
1. Isolated native endothelial cells, obtained by treatment of rabbit aortic endothelium with papain and dithiothreitol, were voltage clamped, and single channel (unitary) and spontaneous transient outward currents (STOCs) were recorded from both whole cells and excised membrane patches. 2. In inside-out patches, the reversal potential of unitary currents wa
