Gene transfer technology may lead to an HIV vaccine

A research team may have broken the stubborn impasse that has frustrated the invention of an effective HIV vaccine, by using an approach that bypasses the usual path followed by vaccine developers.

Genetic basis for environmental and occupational respiratory diseases

Exposure to particulate matter has been recognized as a contributing factor to lung cancer development for some time, but a new study indicates inhalation of certain particulates can actually cause some genes to become reprogrammed, affecting both the development and the outcome of cancers and other diseases.

Could sleep be a critical component to maintaining a healthy body weight?

Could sleep be a critical component to maintaining a healthy body weight? According to new research to be presented on Sunday, May 17, at the American Thoracic Society's 105th International Conference in San Diego, body mass index (BMI) is linked to length and quality of sleep in a surprisingly consistent fashion.

Combining two chemotherapy drugs with Herceptin shows promise for metastatic HER2+ breast cancer

At the 45th Annual Meeting of the American Society of Clinical Oncology (ASCO), researchers from the Mayo Clinic campus in Florida report that using a combination of capecitabine, vinorelbine, and trastuzumab offers a treatment option that is at least as beneficial as other current options - and doesn't cause hair loss in patients.

Low oxygen levels in prostate tumors can predict recurrence

Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer.

Biological timekeeper studies reveal new temperature regulator and track clock protein across a day

Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities, according to two studies published May 15.

Amino acid glutamine show promise in treating stomach ulcers

Nearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the bacteria is growing increasingly resistant to antibiotics.

A link found between atrial fibrillation and Alzheimer's disease

Researchers at Intermountain Medical Center in Salt Lake City believe that they have made a breakthrough connection between atrial fibrillation, a fairly common heart rhythm disorder, and Alzheimer's disease, the leading form of dementia among Americans.

Study compares aspirin types

For many years, it has been known that aspirin is beneficial to patients suffering heart attacks and near-heart attacks. But which of the many different types of aspirin is likely to help the most?

Early use of antiretroviral treatment improves survival rate of HIV patients

A clinical study, led by researchers from University College Dublin, Ireland, and Stanford University, California, USA, with international collaborators, demonstrates that mortality rates of HIV patients can be almost halved when early antiretroviral (ARV) therapy is added to the treatment of AIDS-related opportunistic infections (OIs) such as pneumonia, meningitis or other serious bacterial infections.

Variation of natural compound cures malaria in mice

Approximately 350 million to 500 million cases of malaria are diagnosed each year mostly in sub-Saharan Africa. While medications to prevent and treat malaria do exist, the demand for new treatments is on the rise, in part, because malaria parasites have developed a resistance to existing medications.

Early identification of dementia increasingly difficult

If grandma seems to forget things, will she end up demented? These days, memory loss is one of the very few symptoms that may signal which 70-year-olds risk developing dementia. This is shown in a doctoral thesis at the Sahlgrenska Academy at the University of Gothenburg, Sweden.

A relationship found between cancer stem cells and prognosis in primary breast cancer

Breast cancer patients who received chemotherapy prior to surgery had heightened levels of cancer-initiating stem cells in their bone marrow, and the level of such cells correlated to a tumor's lymph node involvement, according to research from The University of Texas M. D. Anderson Cancer Center.

Chronic infection clearly linked to key immunity protein

The reason deadly infections like human immunodeficiency virus (HIV) and hepatitis C never go away is because these viruses disarm the body's defense system.

Common gene variation explains why some women may find it more difficult to quit smoking during pregnancy

Researchers from the Peninsula Medical School and the University of Bristol, using data from the Avon Longitudinal Study of Parents and Children and the Exeter Family Study of Childhood Health, have identified a common genetic variant that explains why some women may find it more difficult to quit smoking during pregnancy.

Determining success or failure in cholesterol-controlling drugs

Researchers at the University of California, San Diego have discovered that a complex network of interactions between drugs and the proteins with which they bind can explain adverse drug effects. Their findings suggest that adverse drug effects might be minimized by using single or multiple drug therapies in order to fine-tune multiple off-target interactions.
