Call from China for joint nanotech toxicity-testing effort

Pertussis Vaccine Testing for Freedom-from-toxicity.

The results of 9.5 years of official testing of vaccines containing pertussis vaccine, plain or adsorbed with alum, Al(OH)(3), or AlPO(4), are reported. Toxicity was evaluated by weight changes in mice at 3 and 7 days after injection and intercurrent deaths. Toxicity was encountered during the early use of AlPO(4) in pertussis vaccine products, with a special product and quadruple-antigen vacci...

ACCIDENT and Emergency Medicine is a relatively new but rapidly expanding specialty, and although many textbooks related to it have been published in recent years for doctors, the same has not occurred for nurses. This book, written by a team of doctors in Lancaster, covers a wide range of the emergencies and not so acute conditions seen in every casualty department, and the nurse is given very...

Dynamic Model for Maintenance and Testing Effort

The dynamic evolution of ecological systems in which predators and prey compete for surviving has been investigated by applying suitable mathematical models. Dynamic systems theory provides a useful way to model interspecie competition and thus the evolution of predators and prey populations. This kind of mathematical framework has been shown to be well suited to describe evolution of economica...
