Pfizer and Peter MacCallum support the future of cancer research in Australia

Australia's reputation for excellence in cancer research has been strengthened with the launch of the Peter MacCallum Pfizer Translational Oncology Research Collaborative Hub (TORCH) at the Peter MacCallum Cancer Centre, by the Minister for Innovation, Industry, Science and Research, Senator the Hon. Kim Carr.

New Wilmot Cancer Center offers expanded care, research for cures

The University of Rochester Medical Center (URMC) today celebrates the expansion of cancer care and research as it dedicates the new James P. Wilmot Cancer Center. The Center introduces leading-edge technology, greater access to multidisciplinary care, a new model for breast care, and more opportunities to receive tomorrow's therapies today.

Drug therapy for phenylketonuria reverses heart damage

A pricy drug used to treat a rare but well-known genetic disorder may hold wider promise as a treatment for millions of Americans with potentially lethal enlarged hearts, due mainly to high blood pressure, a study from Johns Hopkins shows.

Supplemental breast ultrasound boosts cancer detection, radiologist reports in national study

Among women at high-risk of developing breast cancer, breast ultrasound combined with mammography may detect more cancers than mammography alone, according to results of a multicenter trial that included UT Southwestern Medical Center researchers.

Study looks at phantom limb syndrome

Losing a limb can be a traumatic experience and, in some cases, emotional and physical pain can linger for years. To better understand the phenomenon, dubbed "phantom limb syndrome," Université de Montreal graduate student Emma Duerden is inviting amputees to come forward and share their experiences for a major study.

New MRI technique detects subtle but serious brain injury

A new technique for analyzing magnetic resonance imaging data, developed by researchers at UT Southwestern Medical Center, can reveal serious brain injury missed by current tests and help predict a patient's degree of recovery.

Fruit fly avoidance mechanism could lead to new ways to control pain in humans

At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs.

Big differences in depressed brains

Depressed people may have far fewer of the receptors for some of the brain's "feel good" stress-response chemicals than non-depressed people, new University of Michigan Depression Center research shows.

Research reveals workings of anti-HIV drugs

Using ingenious molecular espionage, scientists have found how a single key enzyme, seemingly the Swiss Army knife in HIV's toolbox, differentiates and dynamically binds both DNA and RNA as part of the virus's fierce attack on host cells. The work is described this week (May 7) in the journal Nature.

Nanoworms developed to target tumors

Scientists at UC San Diego, UC Santa Barbara and MIT have developed nanometer-sized "nanoworms" that can cruise through the bloodstream without significant interference from the body's immune defense system and-like tiny anti-cancer missiles-home in on tumors.

Color Doppler ultrasound should be first imaging technique for diagnosing suspected acute appendicitis

Color Doppler ultrasound, not CT, should be the first imaging examination for adult patients with suspected acute appendicitis, a new study emphasizes.

Scientists discover how reverse transcriptase molecules interact with the HIV genome

Using ingenious molecular espionage, scientists have found how a single key enzyme, seemingly the Swiss army knife in HIV's toolbox, differentiates and dynamically binds both DNA and RNA as part of the virus' fierce attack on host cells. The work is described this week in the journal Nature.

New journal - Circulation: Heart Failure

The American Heart Association has named the editor of Circulation: Heart Failure, its second of the planned six-publication extension to the weekly flagship journal, Circulation: Journal of the American Heart Association. The journals will be published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Gut hormone makes food appear more desirable

A gut hormone that causes people to eat more does so by making food appear more desirable, suggests a new report in the May issue of Cell Metabolism, a publication of Cell Press. In a brain imaging study of individuals, the researchers found that reward centers respond more strongly to pictures of food in subjects who had received an infusion of the hormone known as ghrelin.

New laser treatment for vocal-cord cancer

An innovative laser treatment for early vocal-cord cancer, developed at Massachusetts General Hospital (MGH), successfully restores patients' voices without radiotherapy or traditional surgery, which can permanently damage vocal quality.

Autonomous robot surgery a step closer

The day may be getting a little closer when robots will perform surgery on patients in dangerous situations or in remote locations, such as on the battlefield or in space, with minimal human guidance.

New scanner opens up new possibilities for patients

Dolphins swimming underwater, jet planes whizzing overhead, and monkeys climbing up palm trees are just some of the images patients are now seeing at Strong Memorial Hospital as it introduces the region's first "open" high-field magnetic resonance (MRI) scanner.

Better understanding of immune response to HIV infection

The "exhaustion" of immune cells that target HIV appears to result from chronic exposure to the virus, specifically exposure to the particular protein segments targeted by the pathogen-killing HIV-specific CD8 T cells.

New concept sends medical images via cellular phones

A process to transmit medical images via cellular phones that has been developed by a Hebrew University of Jerusalem researcher has the potential to provide sophisticated radiological diagnoses and treatment to the majority of the world's population lacking access to such technology.

Alcohol affects threat-detecting brain circuits

New brain imaging research published this week shows that, after consuming alcohol, social drinkers had decreased sensitivity in brain regions involved in detecting threats, and increased activity in brain regions involved in reward.
