Genomic study of malaria parasite unearths surprising behaviors (12/1/2007)

The malaria parasite has been studied for decades, but surprisingly little is known about how it behaves in humans to cause disease. Now an international team including scientists at the Broad Institute of MIT and Harvard has for the first time measured which of the parasite's genes are turned on or off during actual infection in humans, unearthing surprising behaviors and opening a window on the most critical aspects of parasite biology. ...> Full Article

UCSD Offers Free Test That Can Detect HIV as Early as One Week after Exposure (12/1/2007)

UC-San Diego's Antiviral Research Center (AVRC) is offering free and confidential HIV testing to people who may have a very recent infection with HIV, the retrovirus that can lead to AIDS. The Early Test Program - offered in collaboration with the San Diego County Health and Human Services Agency - offers a new test method that checks for the presence of the HIV virus, which can be detected within a week of infection. In contrast, a regular HIV test looks for antibodies in the blood, which can take three months or more to detect. ...> Full Article

Genetic and Behavioral Differences Add to Prostate Cancer Disparities (11/30/2007)

African-American men face an observable disadvantage versus Caucasian men when it comes to prostate cancer survival. Not only is prostate cancer detected later in African-Americans, it is often more aggressive and harder to treat. ...> Full Article

Stem-Cell Transplant Increases Oxygen In Damaged Heart (11/30/2007)

Scientists have determined that stem cells transplanted into a damaged heart can increase the presence of oxygen at the site of injury, suggesting that such transplants might someday be used as therapy after heart attacks and for other diseases characterized by a lack of oxygen. ...> Full Article

Researchers identify key genetic trigger of acute myeloid leukemia (11/29/2007)

A gene called N-Myc leads a double life in certain white blood cells when it is overexpressed, helping to trigger a cancer called acute myeloid leukemia (AML) under some conditions while triggering apoptosis, or cell suicide, under other conditions, according to results of a mouse study done by investigators at St. Jude Children's Research Hospital. ...> Full Article

Yeast behind potentially deadly infections tackled by multi million pound collaboration (11/29/2007)

How yeast infections fight off multiple attacks from the human immune system is the subject of a new study awarded £4.6 million today. The team of internationally renowned scientists receiving the grant hope their findings could pave the way for better and more effective anti-fungal drugs. ...> Full Article

By growing 3D tumors, researcher develops realistic cancer growth models (11/29/2007)

Scientists can only develop new cancer drugs or search for cures by testing their theories on the real thing. Traditionally, they've done so by culturing cancer cells on petri dishes or plastic slides. But those cancer cells do not behave the way they do in the body. They only partially re-create the aggressive behavior of tumors in real patients. ...> Full Article

Freezing Bone Cancer Tumors Reduces Pain (11/29/2007)

Cryoablation, a procedure most commonly associated with destroying kidney and prostate tumors by freezing them, has been shown to offer durable pain relief of cancer that has spread to bone. The procedure freezes and shrinks or destroys cancerous tumors in or near bone. ...> Full Article

Cancer-resistant Mouse Developed By Adding Tumor-suppressor Gene (11/29/2007)

A mouse resistant to cancer, even highly-aggressive types, has been created by researchers at the University of Kentucky. The breakthrough stems from a discovery by UK College of Medicine professor of radiation medicine Vivek Rangnekar and a team of researchers who found a tumor-suppressor gene called "Par-4" in the prostate. ...> Full Article

For treating malaria, less drugs may be best drugs (11/28/2007)

The current dosage of drugs used in treating malaria may be helping the parasites become resistant to the drugs faster, without improving the long-term outcome in patients. According to evolutionary biologists, studies using mice suggest that the optimal use of the drugs might slow the spread of drug resistance while making the patient just as healthy. ...> Full Article

PET and CT Scans Bring New Hope to Patients with Deadly Form of Breast Cancer (11/28/2007)

Researchers are improving the chances of women faced with an aggressive and difficult to diagnose form of breast cancer. Inflammatory breast cancer spreads quickly and can be lethal in six to nine months. But by using fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT), radiologists and physicists are able to spot the spread of cancer earlier, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). ...> Full Article
