Caspase-12 antagonists could potentially be useful in the treatment of sepsis and other inflammatory and immune disorders

According to the new study, the presence of caspase-12, which appears to modulate inflammation and innate immunity in humans, increases the body's "vulnerability to bacterial infection and septic shock" while a deficiency confers strong resistance to sepsis. This new discovery suggests that caspase-12 antagonists could be a potentially useful in the treatment of sepsis and other inflammatory and immune disorders.

New drug may revolutionize how chronic iron overload is treated in chronic anemia patients

Those with severe chronic anemias need frequent blood transfusions to remain healthy, but such frequent transfusions can cause a potentially deadly buildup of iron in the body, leading to heart and liver failure. The traditional treatment to remove excess iron is so onerous that many patients choose to forgo it, putting their own lives at risk. The results of an international study on deferasirox, a new drug that may revolutionize the way chronic iron overload is treated, will be published in the May 1, 2006, issue of Blood, the official journal of the American Society of Hematology.

Four subtypes of blood cancer identified

Scientists at Dana-Farber Cancer Institute and collaborators have identified four distinct genetic subtypes of multiple myeloma, a deadly blood cancer, that have different prognoses and might be treated most effectively with drugs specifically targeted to those subtypes.

Blood pressure readings lower if patients are allowed to relax and be comfortable

According to a new study from a team of nurses headed by Melly Turner, R.N., systolic blood pressure can be an average of 14 points higher when taken immediately after arriving in the exam room and sitting on an examination table rather than sitting in a chair with your back supported and feet flat on the floor. In fact, all study participants had lower systolic and diastolic blood pressure measurements when seated in a chair versus the exam table.

Blood cancers may be caused by inactivation of a "tumor suppressor" gene

The discovery of a gene, called PRDM1, as a tumor suppressor sheds new light on the cause - and possible treatment - of diffuse large B-cell lymphomas (DLBCLs), a cancer of the blood's B-lymphocytes. DLBCLs comprise about 30 percent of non-Hodgkin's lymphomas.

'Resonance' may be the reason for virologic failure in STI drug therapy

Researchers have been puzzled over why HIV-positive patients who have periodic, built in interruptions in their drug therapy reach a point where the therapy no longer reduces their viral loads, even in the absence of any evidence of acquired drug resistance.

Alternative anti-inflammatory drugs promise less cardiovascular problems

New type of anti-inflammatory drugs may reduce COX-2 cardiovascular problems, says Queen's researcher

Study shows drugs work differently in the brains of men and women

A Johns Hopkins discovery could lead to tailored treatments for drug abuse and neurological diseases after providing what is believed to be the first evidence in people that amphetamines have a greater effect on men's brains than women's.

Genetic clue found to Chronic Fatigue Syndrome

According to researchers from the Centers for Disease Control and Prevention (CDC), in the United States, there may well be a genetic reason why some people develop Chronic Fatigue Syndrome (CFS).

Kidney treatments may be improved with new understanding of cell death mechanism

Finding how two proteins conspire to get kidney cells to self-destruct when oxygen supplies are low may one day improve dismal mortality rates for ischemic renal failure, researchers say.

Research into toxins points to development of better medicines

Researchers have combined magnetic resonance spectroscopy with special protein synthesis procedures to uncover how potassium channels and toxins combine and change in structure. This work could make it possible to develop medications for high blood pressure and many other diseases connected to potassium channel failure .

Arf gene loss enhances oncogenicity and limits imatinib response in mouse models of Bcr-Abl-induced acute lymphoblastic leukemia

New clues to why some kinds of leukemia are more aggressive and deadly than others are coming from research examining the types of genetic damage that allow some blood cells to grow out of control, scientists report.

Drug combo might beat type 1 diabetes

Scientists in California have developed a cocktail of drugs which can reverse diabetes and say the discovery is an important step towards a potential cure.

Corticosteroids do not improve survival in patients with late-stage acute respiratory distress syndrome

The study is the first multi-center randomized clinical trial to evaluate the effects of moderate doses of steroids in ARDS patients when treatment is started 7 days or more after the onset of the condition.

Magnetic nanotechnology holds promise in fighting cancer

Detecting cancer and reinventing computing are two challenges that seemingly have little, if anything, to do with each other. That is, unless you are a nanotechnologist like Shan Wang, an associate professor of materials science and engineering and of electrical engineering at Stanford.
