ZnO was submitted to different conditions of high-energy ball milling to thoroughly study the outcome of mechanochemical activation. Structural modifications led to a decrease in crystallite size and an increase in micro-strain and specific surface area (SBET) with milling time. Different copper amounts were added on pristine (reference) and activa...

RESUMEN Introducción: La metástasis ósea constituye la enfermedad maligna más frecuente que afecta al hueso y es responsable de la mayor parte de la morbimortalidad de la enfermedad tumoral maligna.

Commercial ZnO was subjected to high-energy milling to introduce structural modifications, which can result in a different metal-support interaction. The milling time (0 to 960 min) and vial material and mill balls (WC and ZnO2), were modified. The supports were characterized by XRD, Scherrer, SBET and Raman Spectroscopy. With the increase in milli...

RESUMEN La gastroparesia se define como un retardo en el vaciamiento gástrico en ausencia de obstrucción mecánica, asociado a síntomas por más de tres meses. El diagnóstico de elección se realiza mediante la centellografía del vaciamiento gástrico con una comida radiomarcada, lo que parece ser el estudio más confiable y fisiológico. Una vez realiza...

Introduction: gastroparesis is defined as a delay in gastric emptying in the absence of mechanical obstruction, associated with symptoms such as nausea and/or vomiting, postprandial gastric fullness feeling, early satiety or epigastric pain for more than 3 months. Diabetes mellitus and idiopathic are the most frequent causes related. The gold stand...
