The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the i...

background: cytomegalovirus (cmv), a problematic virus in solid organ transplant recipients (sotr) such as liver, can worsen overall mortality and transplant outcome, so its prevention and treatment is a key of success in such patients. this study is aimed to compare the efficacy of ganciclovir (gcv) and valganciclovir (vgc) for prevention and treatment of infection with cmv. materials and meth...
