Exceeding rates observed in previous research, a new study found four out of five sexually active adolescent women infected with human papillomavirus, a virus linked to cervical cancer and genital warts. Darron R. Brown and colleagues of Indiana University School of Medicine studied 60 adolescent women, ages 14 to 17, at three primary care clinics in Indianapolis. They reported their results in the Jan. 15 issue of The Journal of Infectious Diseases, now available online.
Human papillomavirus (HPV) infection is a common sexually transmitted infection whose effects may range from asymptomatic carriage of the virus to genital warts to cervical cancer. In this study, 95 percent of the subjects were sexually active, and the median number of sexual partners was two. Eighty-five percent were African American, 11 percent were Caucasian, and 3 percent were Hispanic.
Participation in the study involved quarterly visits to a primary care clinic for a cervical swab test and up to five 3-month diary collection periods during which subjects recorded their sexual behavior daily and performed self-vaginal swabbing weekly. Each woman participated in the study for an average of two years. Brown and colleagues collected a total of about 2,100 swab specimens adequate for analysis of HPV infection.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
