Exposure to secondhand cigarette smoke increases the risk of developing cervical tumors, according to researchers at the Johns Hopkins Bloomberg School of Public Health and School of Medicine. The researchers’ results also corroborated past studies that found an association between active cigarette smoking and cervical neoplasia—the growth of a tumor. The concept of the Hopkins study was the result of collaboration between several researchers supported by the Maryland Cigarette Restitution Fund. The study is published in the January 2005 issue of Obstetrics & Gynecology.
“An association between active cigarette smoking and cervical cancer has been noted in numerous studies, but less is known about the potential link between passive smoking and the development of cervical neoplasia. When these new data for cervical cancer are considered in light of similar results from previously published studies, our findings suggest that passive smoking may be firmly linked with cervical cancer,” said Anthony J. Alberg, PhD, MPH, senior author of the study and an assistant professor in the Bloomberg School of Public Health’s Department of Epidemiology. “Our study of two large cohorts found that women who lived with smokers had a 40 percent or greater risk of developing cervical neoplasia.”
The Hopkins researchers examined the personal cigarette smoking and household passive smoking exposures of two Washington County, Md. , cohort groups in 1963 and 1975. Questionnaires from the two groups, which totaled 51,173 women, were compared to the Washington County cancer registry. The researchers found a stronger association between passive smoking and an increased risk for developing cervical neoplasia in the earlier cohort study—a 2.1-fold increased risk of cervical neoplasia in 1963 and a 1.4-fold increased risk in 1975.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
