At present, the rapid diagnosis of pulmonary tuberculosis rests with microscopy. However, this technique is insensitive and many cases of pulmonary tuberculosis cannot be initially confirmed. Nucleic acid amplification techniques are extremely sensitive, but when they are applied to tuberculosis diagnosis, they have given variable results. Investigators at(More)
To deal effectively with a continuously changing environment, our cognitive system adaptively regulates resource allocation. Earlier findings showed that an avoidance orientation (induced by arm extension), relative to an approach orientation (induced by arm flexion), enhanced sustained cognitive control. In avoidance conditions, performance on a cognitive(More)
A plasmid carrying a promoterless herpes simplex virus thymidine kinase gene was transfected via calcium phosphate precipitation into LM (tk-) mouse fibroblast cells. The transfected gene was efficiently expressed, as the transfected cells grew perfectly well in selective hypoxanthine-aminopterin-thymidine medium, suggesting that the thymidine kinase-coding(More)
Fragestellung: Es sollte geprüft werden, ob der Einsatz der Polymerasekettenreaktion in der Keuchhustendiagnostik wesentliche Vorteile gegenüber den traditionellen Nachweismethoden erbringen kann, insbesondere, ob die PCR eine Erhöhung der Sensitivität und eine Verkürzung der Nachweisdauer bewirkt. Methode: PCR und kultureller Nachweis von Bordetella(More)
prevalence group not only for HBV but even more so for HCV. Conclusion. On the basis of the high prevalence of circulating HCV found with both HCV PCRs, one might speculate that chances for transmission of HCV among IVDU occur more frequently than for transmission of HBV via similar routes. Conversely, instead of transmission through needle sharing or(More)
