Os princípios do teste de ames (Salmonella/microsomo) e sua aplicabilidade

Genética na Escola, 2011
A avaliação das substâncias em relação à mutagenicidade e genotoxicidade são baseadas em uma combinação de testes que servem para a detecção dos possíveis danos genéticos associados a doenças humanas: mutação genética (mutações pontuais, ou seja, exclusões/inserções que afetam os genes); clastogenicidade, ou seja, alterações cromossômicas estruturais ...

Effekte des adaptiven Testens auf die Motivation zur Testbearbeitung am Beispiel des Frankfurter Adaptiven Konzentrationsleistungs-Tests

Diagnostica, 2009
Zusammenfassung. Seit den 1970er Jahren wird weithin angenommen, dass adaptives Testen im Vergleich zu nicht-adaptivem Testen eine motivationssteigernde Wirkung hat. In den letzten Jahren wurde jedoch wiederholt auch die gegensätzliche Sichtweise vertreten, dass sich adaptives Testen motivationsmindernd auswirken kann.

Detección de mutagenicidad en compuestos N-Nitroso con el test de Ames

2006
There are a lot of natural or synthetic products with possible mutagenic capacity. Among these, N-nitroso compounds, that are formed by nitrosation reactions between nitrite and amines or amides in acidic medium, can also be formed into the organism. The Ames test is an efficient tool for detecting these mutagenic compounds, as pure ones or as part of ...
