Maria de los Angeles Araceli Diaz Ruiz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8680156
    Abstract: The present invention aims to demonstrate that a soluble pharmaceutical formulation can be prepared of N,N?-Diamino-diphenyl sulfone which is useful in the development of an ideal drug for use against cerebral infarction, epilepsy, traumatic spinal cord injury, cranio-encephalic trauma, leprosy, Pneumocystis carinii infections and any condition which requires rapid and complete absorption of the compound. As a representative example of this application, the dissolution of N,N?-Diamino-diphenyl sulfone was evaluated as a neuroprotector in a model of acute cerebral infarction in rats. In this study, N,N?-Diamino-diphenyl sulfone showed significant prevention of brain damage, without presenting adverse effects in animals. It is also shown that the soluble pharmaceutical formulations prepared in this manner produce peak blood levels 30 minutes from oral administration and immediately via the intravenous route.

  • Patent number: 8563626
    Abstract: The purpose of the present invention is to demonstrate that semiconducting and non-biodegradable implants made with polypyrrole and polyethylenglycol copolymers and iodine-doped and plasma-synthesized pyrrole polymers, have a neuroprotector effect and induce the reconnection of the spinal cord after an injury; this effect was proved in a model involving a complete section of the spinal cord in rats; the results o the functional evaluation demonstrated 5 times greater recovery in animals implanted with the polypyrrole-polyethylenglycol copolymer compared with the control group which only underwent a complete section of the spinal cord; in addition, the functional recovery of the group with iodine-doped polypyrrole was ten times greater compared to the control group; in the histological study various inflammatory and immune cells were identified at the injury site in the three experimental groups with and without implants and the integration of the polymers in the nervous tissue of the spinal cord was also obse
