| Genetic mutations that cause common childhood brain tumors identified Posted: 22 Jul 2012 10:52 AM PDT Researchers have identified several gene mutations responsible for the most common childhood brain tumor, called medulloblastoma, adding evidence to the theory that the diagnosis is a group of genetically distinct cancers with different prognoses.  |
| New genomic sequencing method enables 'smarter' anaysis of individual cells Posted: 22 Jul 2012 10:52 AM PDT A novel genomic sequencing method called Smart-Seq can help scientists conduct in-depth analyses of clinically relevant single cells. Smart-Seq has many possible applications, including helping scientists to better understand the complexities of tumor development.  |
| Among new HIV treatment recommendations, all adult patients should be offered antiretroviral therapy Posted: 22 Jul 2012 10:51 AM PDT Included in the 2012 International Antiviral Society-USA panel recommendations for human immunodeficiency virus patient care is that all adult patients, regardless of CD4 cell count, should be offered antiretroviral therapy.  |
| Working toward an AIDS-free generation Posted: 22 Jul 2012 10:51 AM PDT Ending the global HIV/AIDS pandemic may be possible by implementing a multifaceted global effort that expands testing, treatment, and prevention programs, as well as meets the scientific challenges of developing an HIV vaccine and possibly a cure.  |
| New line of approach for combination therapy against Melanoma Posted: 22 Jul 2012 10:50 AM PDT A melanoma is a malignant form of skin cancer and is one of the most aggressive types of tumors there is. Treatment is particularly difficult, because melanomas are usually resistant against conventional chemotherapy treatments. Medical researchers have now found a new line of approach in which to treat these aggressive skin cancers, namely by combating the interaction between the protein MDM4 and the tumor suppressor p53.  |
| HPV testing in HIV-positive women may help reduce frequent cervical cancer screening Posted: 22 Jul 2012 10:50 AM PDT Compared to the general population, HIV-positive women have a high risk of cervical cancer and thus are advised to undergo more frequent screening tests. This creates a burden for HIV-positive patients and the health care system, leading to frequent biopsies, which often do not reveal clinically relevant disease.  |
| Benefits of HIV drugs rise, but less than previously believed Posted: 22 Jul 2012 10:50 AM PDT The percentage of HIV patients taking antiretroviral drugs who experienced the full benefit of the drugs jumped from 45 percent of 72 percent during the past decade, a figure that is lower than previous estimates. The findings are considered important for HIV prevention efforts since patients whose virus is in tight control are less likely to transmit the infection to others.  |
