Breeding a better vector
| August 7, 2000
DNA shuffling (also called molecular breeding) generates variation by random fragmentation of a cloned gene followed by reassembly of the fragments in a self-priming polymerase reaction. The result is a recombination of overlapping fragments that have different mutations or come from different, naturally occurring homologous genes. In the August Nature Genetics Soong et al apply this technique to a pool of six different murine leukemia virus envelope sequences to derive a new virus that can,

Smoking and diabetes
August 3, 2000
NEW YORK, August 2 (Praxis Press) Ethnic and lifestyle factors may play a role in the relationship of cigarette smoking and the development of type 2 diabetes. Nakanishi and colleagues studied the association of smoking and the development of impaired fasting blood-glucose and type 2 diabetes in 1,266 middle-aged Japanese men. The relative risks of developing impaired fasting glucose and type 2 diabetes increased with the number of cigarettes smoked per day. Compared with never-smokers, men who
Stavudine and liver function
August 3, 2000
NEW YORK, August 2 (Praxis Press) At least 40 cases of hepatic steatosis and lactic acidosis have been reported in HIV-infected patients taking zidovudine and didanosine, but this syndrome has only rarely been reported in patients taking stavudine. Miller and colleagues reported four cases of hepatic steatosis, lactic acidosis, and myopathy in HIV-infected patients taking stavudine as part of a multidrug antiretroviral regimen. All patients had marked lactic acidosis, elevated levels of alanine

Family history screen
August 2, 2000
NEW YORK, July 31 (Praxis Press) Family history of mental illness is a risk for many disorders. Brief screens such as the Family History Screen (FHS) to collect lifetime family psychiatric history are useful in clinical practice. However, their validity compared to other methods has not been fully established. Weissman and colleagues assessed the performance of the FHS in relation to the best estimate (BE) diagnosis as a standard. They analyzed data on the validity against the BE diagnosis based
