The Early-7 (E7) protein of HPV binds to the underphosphorelated form of the tumor suppressor protein - pRb and displaces the E2F transcription factor that is normally bound by pRb. The latent membrane protein-1 (LMP-1) of EBV prevents apoptosis of B cells by up regulating the expression of bcl-2, and it activates growth promoting pathway that are normally triggered by T cell - derivate signal.

Human Papillomavirus has emerged as a distinct cause of cervical changes in young women. Its prevalence is continuously growing and is considered at epidemic proportions with 20 million Americans already infected and 5.5 million new cases reported annually.

Prophylactic human papillomavirus vaccines have been shown to be effective in reducing the disease burden of cervical cancer, but the three dose regimen can be expensive and difficult to complete. With that in mind, Dr Aimée R. Kreimer, investigator in the division of cancer epidemiology and genetics at the National Cancer Institute, the National Institute of Health, and colleagues sought to determine if less than three doses of the vaccine would be effective. The results are published in the Journal of the National Cancer Institute.

In light of ongoing threats of radiation exposure during the earthquake, tsunami, and nuclear crisis in Japan, OBGYN.net has put together a list of resources and information for doctors and patients who want to learn more about the dangers of radiation and exposure during pregnancy.

This review describes the use of polymer micelle nanotechnology based chemotherapies for ovarian cancer. While various chemotherapeutic agents can be utilized to improve the survival rate of patients with ovarian cancer, their distribution throughout the entire body results in high normal organ toxicity.

Since their introduction, cervical cytology screening programs have caused a substantial reduction in cervical cancer rates. However, the low sensitivity of one screen and resulting need for repeated screens during a lifetime to achieve programmatic sensitivity has deemed it inefficient. With that in mind, Dr Philip E Castle, of the American Society for Clinical Pathology in Washington, D.C., and colleagues compared the performance of the cobas human papillomavirus (HPV) test versus liquid-based cytology.

Compared to healthy women, the researchers found significantly higher serum mesothelin antigen levels in women with ovarian cancer, benign conditions, and unexplained infertility. Luborsky and colleagues further noted that mesothelin antibodies had a higher affinity in the infertility groups, especially premature ovarian failure and ovulatory dysfunction, than that in the healthy, benign, or ovarian cancer groups. Specifically, they found significantly higher positive sera in women with premature ovarian failure and ovulatory dysfunction as compared to normal sera.

The most lethal reproductive cancer in women, ovarian cancer, is estimated to affect 12.8 per 100,000 women in the United States. As such, researchers continue to look into novel ways to eradicate the disease. Armed with the knowledge that almost all (90%) ovarian cancers can be characterized by their expression of alpha-folate receptor, Dr De-Gang Song, postdoctoral investigator in the Perelman School of Medicine at the University of Pennsylvania, and colleagues attempted to engineer T cells to see if they would help shrink the cancer tumors.

Learning Objectives At the end of this presentation you should: 1-Enumerate the problems a woman affected with celiac disease may encounter during her life 2-Be aware of the methods of diagnosis of celiac disease 3-Describe effective control for the disease to minimize symptoms and long term sequelae of the disease
