The realization of the photo-electrochemical process consists in percolating the solution to be treated through an electrolytic reactor, in which the anodes coated with metal oxides remains under the effect of ultraviolet radiation (UV). The solution used in this study was contaminated artificially from fecal samples positive for bacteria and intestinal parasites. The evaluation of the process for the disinfection of water was held in photo-electrical-chemical reactor, with a total volume of 10.0 Lper batch system contaminated with human fecal material. It was used as the -1supporting electrolyte solution of sodium perchlorate at 0.1 mol. Land applying a current density -1of 14 mAwith the aid of a source and a flow rate of 250 L.h. The UVradiation was provided by a mercury vapor lamp of 55 Wwithout bulb shield. The center electrode is inserted through a quartz bulb. Samples were analyzed...

La Neurocisticercosis (NCC) es la infección del Sistema Nervioso Central (SNC) por el estadio larval del parasito platelminto Taenia solium; la epilepsia es la manifestación clínica más común de esta infección y se asocia a procesos inflamatorios como angiogénesis, gliosis y daño neuronal, sin embargo, aún no se ha evaluado si el estrés nitro-oxidativo tiene un rol en el proceso epileptogénico en la NCC. En este estudio se evaluó mediante inmunohistoquímica un indicador de estrés nitro-oxidativo (óxido nítrico sintetasa inducible) y su relación con la presencia de convulsiones recurrentes (epilepsia), así mismo se evaluó si el estrés nitro-oxidativo está asociado a la presencia de esferoides o hinchazón axonal, gliosis (CD68) o astrogliosis (GFAP) en el modelo animal de NCC comparando ratas con NCC que presentan epilepsia, ratas con NCC que no presentan epilepsia y ...

The research was carried out in communities of the Chapra ethnic group, in the Morona district. It is a non-experimental, observational-descriptive, analytical, cross sectional quantitative study. A structured interview was applied to the leaders of the Chapra Autonomous Government and to the Apu of the communities. The reliability of the Cronbach's Alpha instrument is 0.82. The results of the environmental baseline of the abiotic and biotic environment show that the air remains pure and free of contaminants, and there are no strong winds. The rains are typically from the humid rainforest, fluctuating between 2000 and 3000 mm annually. The annual temperature ranges from a minimum of 22°C to a maximum of 34°C. The soil does not present areas of erosion, salinity, poor drainage, or soil contamination by agrochemicals, but there are localized points of contamination by oil spills and runo...
