Polvos cerámicos de Sm2O3 dopados y mezclados con europio se obtuvieron a partir la formación cloruros samario través ruta sol-gel citrato. Este trabajo reporta influencia los iones en las propiedades estructurales luminiscentes cerámicas Sm2O3:Eu3+ (coordenadas CIE) variando el Eu3+ 10 50% mol. Las características químicas, morfológicas fueron establecidas por FTIR XRD, revelando presencia ban...

OBJECTIVE The objective of this study is to develop and characterize in situ thermosensitive gels for the vaginal administration of sildenafil as a potential treatment of endometrial thinning occurring as a result of using clomiphene citrate for ovulation induction in women with type II eugonadotrophic anovulation. While sildenafil has shown promising results in the treatment of infertility in ...

ATP citrate lyase was purified by two different procedures from the livers of rats first starved and then fed with a fat-deficient and high carbohydrate-glycerol diet. These enzyme preparations were judged homogeneous by sedimentation equilibrium and polyacrylamide gel electrophoresis. The molecular weight of the native enzyme was around 4.4 X 10(5) as determined by sedimentation equilibrium. O...

Crystalline citrate synthase (citrate oxalacetate lyase (coenzyme A-acetylating) EC 4.1.3.7) has been prepared from rat kidney and rat brain. These enzymes are homogeneous as judged by acrylamide gel electrophoresis, and immunologically identical with the rat heart citrate synthase. Steady state kinetic studies including product inhibition experiments indicate that the substrates are added in a...
