Ophidic accident pdf

Alejandro Alagón Cano (Mexico City, 1954) is a Mexican physician, researcher, professor and academic. He has specialized in the areas of antibody biotechnology and toxinology (see toxin), in research for the improvement of antivenoms and the development of new antivenoms. He received the National Award of Sciences and Arts in 2005.

Toxicofera (Greek, 'those that carry toxins') is a clade of squamates that includes the suborders Serpentes (snakes), Anguimorpha (lizards, Gila monster, and alligator lizards) and Iguania (iguanas, agamas, and chameleons). Toxicofera contains about 4600 species, (almost 60%) of the extant squamates. It encompasses all venomous reptile species, as well as numerous related non-venomous species. There is little morphological evidence to support this grouping, however, it has been recovered by all recent molecular analyses.

The newly discovered diversity of squamate species that produce venoms is a treasure trove for those seeking to develop new drugs; many of these venoms lower blood pressure, for example. Previously known venomous squamates have already provided the basis for drugs such as Ancrod, Captopril, eptifibatide, exenatide, and Tirofiban.

We associate PTFE with Teflon, however it is not the same. And there is also the belief that PTFE is toxic. We delve into these issues, based on scientific evidence, to try to clarify these concepts and understand what materials we can use in the kitchen without risks of toxicity and how to use them.

Of all these characteristics, the one we are most interested in investigating is the fact that it is an inert substance, i.e. it does not react with other chemical substances, a subject whose controversy we will study in detail in this document.

Teflon was invented in 1938 and has been used in frying pans since 1961, using PFOA as an emulsifier in the manufacture of PTFE.    That is, PFOA (or another similar substance) was used in the PTFE manufacturing process and only a remnant of PFOA remained in the final product (1).

In 2006, the main PFAS (including PFOA) manufacturing companies committed themselves to seek alternatives and eliminate these substances from products and emissions (2), with scientific backing to prove their safety for health and the environment.

La aplicación AmphibiaWeb proporciona acceso móvil a AmphibiaWeb y ofrece información sobre todas las especies de anfibios (ranas y sapos, salamandras y tritones, y cecilias), incluyendo imágenes, sonidos, así como mapas de distribución y puntos de recogida de especímenes. La aplicación encontrará todos los anfibios de la zona en la que uno se encuentre o podrá buscar anfibios en cualquier lugar del mundo o por su nombre. Se puede navegar por los anfibios por nombre o imagen. Esta aplicación se basa en datos de AmphibiaWeb, un sistema en línea que proporciona acceso a información sobre el declive, la conservación, la historia natural y la taxonomía de los anfibios. Los mapas del área de distribución que se muestran proceden de la Evaluación Mundial de Anfibios de la UICN, 2010-2012. Se requiere conexión a Internet (wifi o móvil). Desarrollador de la aplicación, Mel Roderick Disponible en iTunes: https://itunes.apple.com/us/app/amphibiaweb/id476890286?mt=8

Los voluntarios de NAAMP contribuyen con su tiempo a ayudar a los estados y al USGS a evaluar las tendencias de las poblaciones de ranas y sapos. Los datos se recogen utilizando una técnica de estudio de llamadas, en la que los voluntarios identifican las especies locales de anfibios por sus vocalizaciones o llamadas únicas de reproducción.Más información sobre este proyecto.
