Scientists succeed in creating transgenic primate
— 17:00 GMT | BiologyA team of scientists headed by Erika Sasaki, Laboratory Head of the Central Institute of Experimental Animals, and Professor Hideyuki Okano of the Keio University School of Medicine has succeeded in creating transgenic primates. The expression of an introduced gene was discovered not only in a first generation of common marmosets after introduction, but also in a second. This is the first case ever established in the world that an introduced gene was successfully inherited to next generation in primates…

Research published in the open access journal BMC Urology has shown that 41.8% of patients whose extended core biopsy led to an initial diagnosis of HGPIN were subsequently diagnosed with prostate cancer…
Researchers find no adjustment method fully resolves confounding by indication
— 12:40 GMT | HealthResearchers at Boston University School of Medicine (BUSM) and Boston University School of Public Health have found that no adjustment method fully resolves confounding by indication in observational studies, meaning when the validity of a study is threatened by unmeasured confounding, it is not straightforward to determine which method of adjustment, if any, is most effective in obtaining a valid and precise estimate of effect. The study appears online in the Journal of Clinical Epidemiology…
