The intraganglionic laminar endings in the esophagus of the cat and the rhesus monkey show absolute equivalence between the results in both species from the morphological standpoint. The different types of apparatus found are described, with their location in the esophagus and their percentage distribution in relation to the different portions of its wall.(More)
Considering the economic importance of the tomato and its nutritional benefits to human health, a study was made of how two different environmental factors (temperature and overall solar radiation) influence the nutritional quality of cherry tomatoes during the plant full production cycle. Solanum lycopersicum L. cv. Naomi plants were grown in an(More)
Experiments were carried out to locate carbamoyl phosphate synthetase (CPS) in rat liver by direct immunoferritin labeling. By using Epon sections treated with sodium methoxide, homogenates or mitochondrial and mitoplast fractions, carbamoyl phosphate synthetase was found homogeneously distributed in the mitochondrial matrix. Immunoferritin was detected(More)
The action of doxorubicin, a cancer chemotherapeutic agent, on liposomes of dipalmitoylphosphatidylcholine obtained by extrusion, with or without cholesterol, and on monolayers of the same composition, was determined by photon correlation spectroscopy, penetration kinetics, and adsorption isotherms. Doxorubicin produced a wider vesicle distribution in both(More)
In an attempt to produce sized liposomes with high encapsulation efficiency by a gentle procedure, we compared the encapsulation efficiency in liposomes of three different molecules: carboxyfluorescein (mol.wt 376 Da), protein A (mol. wt 40,000 Da), and a DNA-plasmid pN2 alpha 1AT (9.3 kb). Sized liposomes were obtained by extrusion of multilamellar(More)
