We conducted a prospective study in patients with intestinal strongyloidiasis without known immunodepression who failed to respond to standard therapy with ivermectin or thiabendazole(More)
Better sensing is crucial to improve robotic grasping and manipulation. Most robots currently have very limited perception in their manipulators, typically only fingertip position and velocity. Additional sensors make richer interactions with the objects possible. In this paper, we present a versatile, robust and low cost sensor for robot fingertips, that(More)

Countries of the entire world are overflowed by the need of new strategies, methodologies and technologies to better serve the millions of patients, who demand better medical attention. The present archaic and ephemerally systematized systems widen the gap even more than(More)
The actual challenge for the majority of research centers involves the embryo culture medium, since it is known that the culture medium plays a large role in determining embryo quality. Pterostilbene (PT) is a natural analogue of Resveratrol, an antioxidant that can reduce lipids in embryos, but no reports exist of PT being used with IVF-produced embryos or(More)
