Drinking water is extremely scarce good in the world. Of the estimated 1.4 billion cubic kilometers of water on earth, 97.6% is salt, 2.38% is like ice and glaciers and only about 0.024% is above the earth's surface and therefore may be destined for human consumption. In this situation, the lack of access to drinking water is a serious problem in the world and Peru is no exception. Of the 6 billion people who inhabit the land, over a billion suffer from this problem. However, about 2.5 billion lack access to adequate sanitation. This means that more than 6 million children a year die from diseases that are caused by the water they consume.

El agua potable es un bien sumamente escaso en el mundo. De los estimados 1.4 billones de kilómetros cúbicos de agua sobre la tierra, el 97.6 % es salada, 2.38 % está como hielos y glaciares y aproximadamente solo 0.024 % se encuentra sobre la superficie terrestre y por lo tanto puede ser destinada para el consumo humano. Ante esta situación, la falta de acceso al agua potable es un problema muy serio en el mundo y el Perú no es una excepción. De los 6 billones de personas que pueblan la tierra, más de un billón sufre de este problema. Sin embargo, cerca de 2.5 billones no tienen acceso a un adecuado servicio de saneamiento. Esto se traduce en que más de 6 millones de niños por año mueren por enfermedades que tienen su origen en el agua que consumen.

Objetivos. Determinar las características epidemiológicas y clínicas de la gastroenteritis causada por Vibrio parahaemolyticus del grupo pandémico en el Perú. Materiales y métodos. Se examinó las historias clínicas y registros de laboratorio de cien casos de gastroenteritis en los cuales se aisló V. parahaemolyticus del grupo pandémico y no pandémico. Se recolectó información epidemiológica y clínica y se realizó el análisis estadístico de los datos para evaluar si la gravedad de la enfermedad se asoció con la presencia de las cepas del grupo pandémico. Resultados. Se logró colectar información epidemiológica en 85% de los casos e información clínica sólo en 37% de los casos, principalmente de los hospitalizados. Los casos del grupo pandémico tuvieron una mayor probabilidad de tener deposiciones líquidas (96,3% frente a 62,5%, p<0,05), presentar deshidratació...

The application of nanotechnology has gained importance in the finishing of textile products, imparting them functional properties, which are achieved without affecting the textile. A novel method was developed for the in situ growth of CuO nanoparticles (NPs) onto cotton textiles by the exhaust dyeing method. For functionalised textiles, a constant sodium hydroxide concentration (0.4 g l(-1)) and different percentages of on-weight-fabric (% owf) of copper acetate were used. The textiles were microbiologically evaluated, the laundering durability was assessed and their UV protection factor (UPF) was determined. In addition, their CIE L*a*b* colour coordinates and colour strength (K/S) were studied. The results determined that NPs on the textile were CuO and were distributed randomly on the cotton fibre surface. The functionalised textiles with CuO NPs had percentages of bacterial reducti...
