Currently the increasing number of robotic devices for application in the mobility of people who had suffered some type of spinal cord injury, it is necessary to develop new equipment more adaptable, safe and efficient. Robotic devices that aid in locomotion of paraplegic people can play their function, they must be able to reproduce the lost movements with(More)
The discovery and development of anti-malarial compounds of plant origin and semisynthetic derivatives thereof, such as quinine (QN) and chloroquine (CQ), has highlighted the importance of these compounds in the treatment of malaria. Ursolic acid analogues bearing an acetyl group at C-3 have demonstrated significant anti-malarial activity. With this in(More)
BACKGROUND Insecticide resistance to commonly used substances demands new molecules for the chemical control of the dengue vector Aedes aegypti. Because natural product sources have been an alternative to obtain larvicidal compounds, the aim of this study was to evaluate the triterpenoids betulinic (BA) and ursolic (UA) acids and their semi-synthetic(More)
The medium-term tongue carcinogenesis assay is a useful model for studying oral squamous cell carcinomas phase by phase. The aim of the present study was to investigate the expression of p53 by immunohistochemistry and examine the DNA sequence of exons 5, 6, 7, and 8 of Tp53 for mutations during rat tongue carcinogenesis induced by 4-nitroquinoline 1-oxide(More)
Chinese Hamster Ovary (CHO) cell cultures were grown on surfaces lithographed with periodic 3D hexagonal microcavity array morphology. The range of microcavity size (inscribed circle diameter) was from 12 μm to 560 μm. CHO cells were grown also on flat surfaces. The characterization was performed with respect to cell growth density (number of nuclei per(More)
OBJECTIVE the purpose of this study was to measure ecographically and ascertain the characteristics of the abdominal aorta in a sample of the male population over sixty years, and try to correlate the findings with some so-called "risk factors" most currently quoted in the medical press, such as arterial hypertension, diabetes mellitus, tobacco consumption(More)
