Targeted nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light. When heated with lasers, the actively targeted hollow gold nanospheres did eight times more damage to melanoma tumors in mice than did the same nanospheres that gathered less directly in the tumors.

Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.

Basis of immunity to oral thrush, common in AIDS, identified by UB researchers

Oral thrush, a hallmark symptom in AIDS patients, is caused by a type of yeast that grows unchecked in people with weakened immune systems, and appears in colonies of white patches in the mouth.

Statins can stimulate cardiac muscle cell regeneration, improve heart function

Statins, used widely to treat elevated cholesterol, have been shown to prevent progression of coronary narrowing and to have other beneficial effects on the heart, such as reducing inflammation, that are independent of cholesterol.

Life-giving technology: Camera pills and ultrasound creating maps of the body

For more than ten years, senior medical officer Ronald Marvik at St. Olav's Hospital in Trondheim has been collaborating with SINTEF scientist Thomas Lango. Together, they have created a new IT-base window on the inside of the body, a window that makes a patient transparent on a screen when a surgeon inserts operating instruments through small openings in the abdominal wall.

Tiny cell cultivation chamber of silicon plastic opens new potential in tumor research

Researchers at Uppsala University have developed a new tool that makes it possible to study the signals in the body that control the generation of blood vessels.

Scientists mine drugs database for new diabetes treatment

Scientists funded by the Biotechnology and Biological Sciences Research Council have harnessed a new drug discovery tool to identify a new player in the body's insulin secretion process.

Mice with "superhealing" powers provide clues to treating arthritis caused by traumatic injury

A strain of laboratory mice that has "superhealing" powers has been found to resist inflammation after a knee injury, and also to avoid developing arthritis at the injury site in the long term, according to researchers at Duke University Medical Center.

Laser treatment clinical trial misses primary endpoint

Using a laser to treat cells in the brain did not significantly reduce stroke disability, according to results of the first major clinical trial of laser therapy presented at the American Stroke Association's International Stroke Conference 2009.

Green or black tea reduces stroke risk

Drinking at least three cups of green or black tea a day can significantly reduce the risk of stroke, a new UCLA study has found. And the more you drink, the better your odds of staving off a stroke.

High-flux hemodialysis prolongs survival in chronic kidney disease

High-flux hemodialysis (which removes large toxins) reduces the risk of premature death in many patients with chronic kidney disease (CKD), according to a study appearing in the March 2009 issue of the Journal of the American Society Nephrology (JASN).

Gene therapy shows potential against HIV

A new UCLA AIDS Institute study has found that gene therapy can be developed as a safe and active technique to combat HIV.

Scientists develop mobile sleep lab for home use

Poor sleep can be attributed to many causes, including shift work, stress, snoring or even sleep apnea - a disorder in which the sleeper temporarily stops breathing.

B-cell clones as early markers for chronic lymphocytic leukemia

Testing of blood specimens may detect abnormal white blood cells in patients years before the chronic form of lymphocytic leukemia (CLL) develops, according to research published in the current issue of the New England Journal of Medicine.

Stenting not necessary in late treatment of heart attacks

Two years ago, a major study found that many patients who receive delayed treatment for a heart attack do just as well with drugs alone as they do with drugs plus stents to prop open their blocked arteries.

States expand newborn screening for life-threatening disorders

Regardless of where they are born in the United States, nearly all newborns now receive mandated screening for many life-threatening disorders, a remarkable public health advance of the last four years, according to a new report issued today by the March of Dimes.
