Vax, Inc. stated her research team has revealed the fact that in November 2001 the VRBPAC (Vaccines and Related Biological Products Advisory Committee) mistakenly allowed the vaccine manufacturer […]
Conventional, annual Pap smear cost-effective follow-up after cervical lesion treatment
Science News by administrator on October 21, 2010 (SACRAMENTO, Calif.) A study of the options for reducing cancer incidence and mortality among women who have been treated for precancerous cervical lesions found that an annual conventional Pap smear is a cost effective strategy. Joy Melnikow, professor in the Department of Family and Community Medicine and […]
Understanding Cervical Cancer
Ethiopian Review October 2, 20102 What It Is, the Role of HPV, and How It May Be Prevented What Is Cervical Cancer? The cervix forms the opening to the uterus from the vagina. It is covered with two main types of cells: squamous cells, which cover the part of the cervix that extends into the […]
The Role of Cytology (Pap Tests) and Human Papillomavirus Testing in Anal Cancer Screening
The Body The Complete HIV/AIDS Resource September 27, 2010 In the current study, investigators assessed anal oncogenic human papillomavirus (HPV) and anal cytology as screening tests for detecting high-grade intraepithelial neoplasia (AIN 2+), since this is an immediate precursor to anal cancer. A cross-sectional study of 401 HIV-positive men who have sex with men was […]
Ultrasensitive biosensor can detect proteins, aid in cancer diagnosis
Binding can be read in real time, instead of after days or weeks of laboratory analysis, meaning the nanotube molecular imprinting technique could pave the way for biosensors capable of detecting human papillomavirus or other viruses weeks sooner than available diagnostic techniques currently allow. As opposed to searching for the HPV antibody or cell-mediated immune responses after initial infection, the nanotube sensor can track the HPV protein directly. In addition, no chemical marker is required by the label-free electrochemical detection methods.
