European Stars and Stripes (Newspaper) - November 28, 1992, Darmstadt, Hesse A a a \ Page 6 the stars and stripes . Saturday november 28, 1992harmless virus May help in aids fight Washington a a harmless virus carrying an engineered genetic pattern is Able in test tube experiments to keep the aids virus from reproducing inside its favorite blood cell target researchers report. In a study published Friday in the journal science three scientists said they showed that aids resistance could be inserted into the blood cells using another Type of virus that carries altered genes t he scientists in a Laboratory Experiment inserted into an infection particle called Adco associated virus or Aav a Gene that would stick to a specific part of the genetic pattern contained m the human immunodeficiency virus. The his causes aids. Healthy blood cells called cd4 cells were then infected with the Aav virus. T his caused the new Gene to be incorporated into genetic pattern of the cd4 cell the favored target of the his. When the his was then exposed in Laboratory culture to the altered cd4genes affect divorce risks study suggests new York a genes May play a substantial role in the risk of divorce probably because of the Way they influence a Many a or woman a personality a study of 1,516 sets of twins suggests. Researchers found that identical twins who arc More alike genetically than fraternal twins arc also were More alike in whether they had experienced a divorce. The genetic effect would result mostly from a general influence on personality rather than from any a divorce Gene a said study co author David Lykken. Environmental factors like cultural influences still would play a big role in divorce risk and the genetic effect would not doom people to divorce the researchers said. Lykken and Matt Mcatic psychology professors at the University of Minnesota presented their study in the november Issue of the journal psychological science. Mcgue said another research team has found similar results in another american twin study. In interviews some scientists agreed with the study conclusion but others said the identical twins similarity May have resulted from their growing up together l Yak in said other studies have shown that identical twins reared apart Are just As similar on Many measures As Are those who grew up together. T he study involved 722 pairs of identical twins and 794 pairs of same sex fraternal twins Ages 24 to 52. They answered a questionnaire in 1989 about marriage and divorce. About one fifth of the participants had been divorced. If genes influence divorce risk researchers said identical twins should show More similarity in divorce history because they Are identical genetically. Fraternal twins share Only half their genes on average. Researchers pursued this question if one twin in a pair had been divorced what was the likelihood that the second twin had been divorced too t he answer was 45 percent for identical twins and 20 percent for fraternal twins. The study Quot makes perfect sense Quot although the strength of the genetic influence is. That of environment is unclear said psychologist Mavis he Thorington of the University of Virginia. She also said that although the study contributes to understanding divorce she could not think of a practical Way to use the information in preventing divorces. Neil Kalter a University of Michigan psychologist said genes Are not the Only explanation for the findings because the identical twins grew up in the same family. His cleansed from sperm doctor reports Washington up italian researchers have developed an experimental sperm Quot washing process that appears to allow men infected with the human immunodeficiency virus to safely father children. T he procedure was used by or. A a gusto Simprini of the University of Milan medical school in Milan Italy and his colleagues. They reported using it to artificially inseminate 29 women with sperm from their his infected husbands that had been cleansed of the deadly virus. Fifteen of the women became pregnant and 10 had healthy babies with the oldest now being 3 years old the researchers said. None of the women or the babies apparently had been infected with the virus which causes aids the researchers said the Quot washing involved carefully processing the menus sperm to remove any his or his infected cells. The researchers reported their findings thursday in the British medical journal the lancet. Cells Only a few of the viruses could grow or reproduce. In unaltered cd4 cells the his was Able to replicate the study said. Untreated cd4 cells reproduced about 1,000 times More his than the cd4 cells with the altered genetic pattern the study said. The researchers said the work showed that the Aav was an effective Way to carry a new Gene into blood cells the Aav is taken up by the blood cells and the virus then inserts the new Gene into the nucleus of the cell. When the his enters the cell and tries to take Over the nucleus it is met by the new Gene. The researchers said the new Gene acts like a shield that blocks key processes that the his must perform to reproduce. Work is under Way to test the technique in animals. No human trials will be planned until the animal experiments Are completed researchers said. The study was conducted by Saswati Chatterjee and or. .
