(1955)When liver glycogen was reduced by fasting of the rats or by glyco-genolysis in vitro, 10-4 M DNP had an inhibitory effect on basal oxygen consumption which was proportional to the glycogen content. With initial glycogen ...
-
(1958)The effect of 2,4-dinitrophenol (DNP) on the synthesis of p-aminohippurate (PAH) by rat liver slices under several experimental conditions was studied. A concentration of 0.025 mM DNP inhibits PAH synthesis, and this effect ...
-
(1962)The cerebral cortex of cats with chronic or permanent mesencephalic transections of the brain stem showed both high-voltage, slow-wave synchronized electroencephalographic patterns and low-voltage, fast-wave desynchronized ...
-
(1962)Liver phosphorylase activity was found to be proportional to the caloric intake of the animal. Rats fed for 6 or 10 days an exclusively carbohydrate diet showed a phosphorylase content of the liver similar to animals fed ...
-
(1962)The addition of epinephrine to the incubation medium did not modify significantly and regularly the phosphorylase activity of liver slices prepared from well-fed or fasted rats. Liver phosphorylase was rapidly inactivated ...
-
(1962)IT has been reported that in liver slices glucose is a better precursor of glycogen than glucose 6-phosphate and glucose 1-phosphate1,2. To explain these results and others in the literature, a new pathway from glucose to ...
-
(1963)EVIDENCE that the nature and amount of carbohydrates in the diet significantly influence the activity of several enzymes related to carbohydrate metabolism is now accumulating. Among other enzymes, glucokinase decreases ...
-
(1963)There are ganglion cells in the pigeon retina that respond selectively, some to any edge moving in a particular direction only, others to any vertically moving horizontal edge. This selective response to a specific stimulus ...

(Universidad de Chile., 1964)En este trabajo tiene por objeto confirmar las observaciones acerca de diferencias en el tiempo de aparición y maduración de los antígenos H-2hechas por Müller (14, 20) y extender a un número mayor de alelos y cepas de ...
-
(1965)Apyrase from potato extracts has been purified 200-fold by two different procedures; both procedures furnish an apyrase which splits ATP faster than ADP. By using P32-labeled substrates, it was possible to demonstrate that ...

(Elsevier, 1967)The behaviour of uranium in both organic and inorganic supporting electrolytes is examined, and also the influence of complexing agents on the incision in the curve, dE/dt =f(E). The addition of TEA to supporting electrolytes ...
