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.

Abstract: This relates to mining and mineral or materials treatment industries that deal with gold and silver. Specifically, it is related to the process to recover gold and silver from thiosulfate or thiourea solutions, with an electrolysis that occurs simultaneously on both the anode and cathode. Increased velocity and greatly reduced energy consumption are obtained in relation to those found in conventional electrolytic cells.

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

Abstract: The present invention refers to a new compound containing Silymarin with Carbopol for the treatment of Diabetes Mellitus. This compound morphologically and structurally regenerates the damage that occurs in the pancreatic tissue in Diabetes Mellitus, and regenerates the insulin-producing pancreatic cells (? cells). It therefore regulates the serum levels of this hormone. Furthermore, it restores and maintains the normal concentrations of the blood glucose.

Abstract: Methods and systems for analyzing operation of a cochlear stimulation system. A sound stimulus signal is generated to excite the cochlear stimulation system to operate. During operation, the intracochlear electrodes generate signals into the auditory nerve system. The patient's nervous system's response may be measured as the Electrical Cochlear Response (“ECR”). The ECR can be detected and analyzed for fitting, calibration, performance evaluation and failure detection of the cochlear implant of the patient. Also example methods may be used to estimate the audiometric thresholds of the cochlear implant without the implanted patient's knowledge.

Abstract: The use of dapsone is the first effective treatment against the disabling consequences associated with cerebral infarction in patients. Dapsone was evaluated as a neuroprotector in the cerebral infarction model produced by the occlusion of the middle cerebral artery in rats and in patients suffering from acute cerebral infarction caused by thromboembolism. In both studies, dapsone displayed a reduction of between 70 and 90% in the adverse effects which occur as a consequence of the infarction.

Abstract: This invention relates to a method and apparatus for obtaining and registering the Electrical Cochlear Response (“ECR”). Particularly, the ECR refers to the electrical activity of the auditory nerve and the intracochlear residual tissue located in the neighborhood of an intracochlear stimulation electrode, when an external sound is presented to a Cochlear Implant user, human or animal. Applicants recognize that an ECR can be thought of as a far-field electrical potential registered on the scalp of an implanted patient. Applicants, through their method and apparatus, can extract that potential from the patient's spontaneous electroencephalographic activity (EEG) and measure it by using an averaging algorithm. The Electrical Cochlear Response can be applied for adaptation, calibration, performance evaluation and failure detection of the Cochlear Implant of the implanted patient.

Abstract: A process for the recovery of metal-containing values from an ore and/or from one or more minerals, that are not readily oxidizable and that are susceptible to reduction comprising: subjecting said ore or one or more minerals to reduction in an electrolysis chamber having a single undivided acidic electrolytic medium; the reduction being carried out by hydrogen using a cathode comprising a material that promotes the generation of monatomic hydrogen; whereby one or more metal-containing values is produced in a reduced form.
