Cyclin dependent kinase 5 (Cdk5) is a proline-directed Ser/Thr kinase involved in various biological functions during normal brain development and neurodegeneration. In brain, Cdk5 activity is specific to post-mitotic ...

The evolution of maize (Zea mays L.) is highly controversial given the discrepancies related to the phenotypic and genetic changes suffered by the species, the incidence of human groups and the times in which these changes ...

In this study, we showed the effect of the betamethasone, sulindac and quinacrine alone or combined, on the inflammatory angiogenesis promoted by polyurethane sponge on mice. The main finding reported here is that the ...

In summary, this limited discussion of recent developments concerning a few signaling pathways and associated cellular systems hopefully underscores the importance of multiprotein complex formation in cellular signaling, ...

The relationship between the free radical-induced loss of lysozyme activity and the occurrence of oxidative modifications, evidenced as gain in DNPHreactive carbonyl groups (CO) and loss of tryptophan-associated fluorescence ...

The kidney response to exogenous inducers is known to he different to the liver, but its response to endogenous factors is poorly known. The <ioxidation of palmitoil CoA catalized by the peroxisomes and the lanrir arid ...

The effect of smoking on prolactin levels was studied on women of different nutritional status, at the end of pregnancy and in the first month of lactation Smoking (S, n=74) and non-smoking pregnant (NS, n=67) women were ...

Frizzled/planar cell polarity (Fz/PCP) signaling controls the orientation of sensory bristles and cellular hairs (trichomes) along the anteroposterior axis of the Drosophila thorax (notum) [1-4]. A subset of the ...

The values of soybean proteins (SBP) and bovine serum albumin (BSA) as blocking agents were compared in immunoradiometric (IRMA), western immunoblotting (WIBA) and immunodot (IDA) assays. Protein purification, from soybean ...

Citrus limon seedlings respond to fungat attack inducing the phenylpropanoid pathway producing phytoalexins. The de nero synthesis of one of the main enzymes, phenylalanine ammonia-lyase (PAL), is accomplished after 24 ...
