Conducting studies -both in human and veterinary medicine- of in vitro toxicity, in vivo toxicity, tolerance, pharmacodynamics, test product administration and procurement of non-clinical specimens, biocompatibility of medical devices, murine model embryo transfers, intracytoplasmic microinjection, oocyte vitrification, measurement and analysis of Natural Killer (NK) cell samples, seminogram and semen studies.
Creation of experimental animal models of various human diseases such as diabetes, obesity, hypercholesterolemia, hypertriglyceridemia, acute and chronic myocardial infarction, prostatic hyperplasia, ulcers, pleural adhesions, constrictive pericarditis and abdominal aortic aneurysm, among others. Possibility of working with a variety of animal species: rodents, rabbits, dogs, cats, pigs and sheep.
