Specific variants of genes predict bleeding after heart surgery

Duke University Medical Center researchers have found that the presence of specific variants of genes that control clotting and the contractility, or "tone," of blood vessels can double the ability of physicians to predict those heart surgery patients at greatest risk of bleeding after surgery.

Specific genes play key role in the of regulation of human-blood stem cells

This work is the first to validate gene expression analysis in human stem cells with functional experiments. The findings also suggest that changes in the expression of genes associated with universal cell signaling pathways can have a substantial impact on human stem cell behavior.

Cancer survival comes at its own price

Patients who hear the dreaded words "you have cancer" invariably look forward to the day the doctor tells them "you're cured." But University of Florida researchers say survival often comes at its own price -- the mind may need mending even after the body heals.

Blood clotting combo saves heart patients lives

Two studies presented Wednesday at the American College of Cardiology's annual scientific sessions in Orlando, Fla. have found that the clot-preventing drug Plavix when added to the treatment of people with severe heart attacks helps reopen their clogged arteries and saves lives.

Studies find Aspirin resistance in up to 27% of Aspirin users

While aspirin remains a crucial and cost-effective therapy for the prevention and management of cardiovascular diseases, research suggests that a significant percentage of the 25 million Americans on a chronic aspirin regimen are "aspirin resistant," or do not achieve sufficient antiplatelet effects from aspirin.

St. John's wort increases effectiveness of Plavix

The widely used herbal remedy St. John's wort appears to amplify the action of the popular blood-thinning drug clopidogrel, sold as Plavix, a small new clinical study finds.

New bone marrow model could help people with sickle cell disease

A new model showing how sickle cell blood cells operate within bone marrow is presented at a conference in Austria today. Researchers at Imperial College London, who developed the model, hope that it will eventually be used by clinicians to advance more effective treatments for sickle cell disease.

Blood tests improve within two weeks of quitting smoking

Long-term smokers who quit may benefit from almost immediate improvements in blood platelet function, which could potentially reduce their risk of heart attacks or strokes caused by blood clots, according to a new study in the Feb. 15, 2005 issue of the Journal of the American College of Cardiology.

Clot-dissolving drugs such as tPA may help detect potentially deadly leg clots

A possible diagnostic use for clot-dissolving drugs such as tPA has been found by Medical College of Georgia researchers working to improve a test that identifies potentially deadly blood clots in the legs.

Significant advance toward understanding lifelong process of blood cell formation

A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role of a key gene known to be required for blood cell formation. Information gained from this research will be useful for future studies aimed at directing stem cell differentiation in a variety of potential therapeutic contexts.

Clopidogrel (Plavix®) responses appear normal in largest data set

Although individual patients respond differently to treatment with the anti-platelet medication clopidogrel (brand name Plavix®), those variations appear normal and may not indicate important differences in the effectiveness of treatment, according to a new study (PDF file) in the Jan. 18, 2005 issue of the Journal of the American College of Cardiology.

Further evidence for the role of cyclooxygenases (COX) in heart-disease risk

In two articles, published in Circulation, researchers from the University of Pennsylvania School of Medicine provide further evidence for the role of cyclooxygenases (COX) in heart-disease risk.

Course of injections in childhood might help protect people from heart disease later in life

A course of injections in childhood might help protect people from heart disease later in life. And for those whose arteries are already clogged up, a dose of antibodies could provide immediate benefits. That's the enticing vision raised by animal studies.

Study finds new method can improve chemo survival

Seeking to find a way to lessen patients’ vulnerability to deadly infections following chemotherapy, researchers at the Stanford University School of Medicine have figured out a way to boost the immune function in animals following such treatments.

Hydroxyurea plus aspirin best therapy in patients with essential thrombocythemia who are at high risk for vascular events

A new treatment for an incurable blood disorder proves a worse option for patients' health than an older treatment, according to a study to be presented today during the 46th Annual Meeting of the American Society of Hematology (ASH).

Fossil record of the human immune system reveals antibodies that block cancer metastasis

A team of researchers at The Scripps Research Institute has reconstructed the "fossil record" of the immune systems of a group of human cancer patients to investigate if they had ever produced antibodies against their disease.
