1. Manejo de agua e de fertilizante potassico na cultura de arroz irrigado.
O manejo da agua de irrigacao e as doses e epocas de aplicacao de fertilizantes tornam-se aspectos de extrema importancia no exito do aproveitamento das varzeas para o cultivo de arroz (Oryza sativa L.) irrigado ou este seguido de outras especies. Com o objetivo de comparar distintas formas de manejo de agua e de fertilizante potassico no comportamento do ar

2. Expressão de supressor de sinalização de citocina (SOCS-3) em hipotalamo de rato espontaneamente hipertenso : efeito sobre a excreção renal de sodio induzida pela Angiotensina II / Expression of supressor of cytokine signaling (SOCS-3) in spontaneous hypertensive rat hypothalamus : effect on renal sodium excretion induced by angiotensin II
There is a surprising lack of experimental data on the renal sodium handle mechanisms induced by i.c.v injection of AngII in hypertensive animals. Thus, we hypothesized that a presumable blunted response to centrally injected AngII may contribute to sodium metabolism disturbances observed in SHR. The study was performed after acute i.c.v AngII administration

3. Mechanism of cardiac Na(+)-Ca2+ exchange current stimulation by MgATP: possible involvement of aminophospholipid translocase.
1. The sensitivity of outward Na(+)-Ca2+ exchange current to charged amphiphiles and phospholipids was tested in giant excised inside-out membrane patches from guinea-pig and rabbit myocytes. 2. Screening of membrane surface potentials with dimethonium (10 mM), spermine (200 microM) and spermidine (100 microM) was without effect, while the positively charged

4. Changes in 42K efflux produced by alterations in transmembrane calcium movements in turtle cardiac pace-maker tissue.
1. 42K efflux has been measured from small strips of turtle sinus venosus which were electrically paced. Three different procedures for altering transmembrane calcium influx have been utilized to test whether changes in 42K efflux may be modulated by changes in intracellular calcium levels. 2. No significant changes in the 42K fractional escape rate (FER) we
