Researchers show how bacteria control processes in human cells

Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Link-ping University in Sweden are showing how bacteria control processes in human cells the same way.

Geldanamycin degrades VEGFR2 protein that triggers blood vessel growth

The drug, geldanamycin, is well known for attacking a protein associated with the spread of breast cancer. However, a laboratory-based study found it also degraded a different protein that triggers blood vessel growth.

Pfizer receives FDA approval for Xeljanz to treat rheumatoid arthritis

The U.S. Food and Drug Administration today approved Xeljanz (tofacitinib) to treat adults with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response to, or who are intolerant of, methotrexate.

Brain bleeds in premature babies: an interview with Edward Ahn

Premature babies are born during their third trimester and they are vulnerable to having brain bleeds because their brains are not completely developed. There are some fragile blood vessels that are present in every developing infant, but when the babies are born early, these blood vessels can be subject to changes in blood pressure and changes in breathing patterns and, due to their fragility, they can develop a hemorrhage.

Workout in the catheter lab gives clues to ‘warm-up angina’

Improved coupling of vascular and ventricular circulation during exercise appears to underlie the phenomenon known as warm-up angina, a UK study shows.

Comprehensive overview of vascular risk factors to Alzheimer's disease

Over the last 15 years, researchers have found a significant association between vascular diseases such as hypertension, atherosclerosis, diabetes type 2, hyperlipidemia, and heart disease and an increased risk of Alzheimer's disease.

Sabin initiates Part II of Na-GST-1 vaccine Phase I hookworm trial

The Sabin Vaccine Institute (Sabin) today announced the start of Part II of its Phase I clinical trial of the Na-GST-1 vaccine candidate, marking another major milestone in the progress toward developing a human hookworm vaccine.

Genetic testing valuable in determining etiology for childhood hearing loss

Genetic testing for a certain mutation in pediatric patients is valuable in determining a cause for unexplained hearing loss, according to a study in the November 2012 issue of Otolaryngology-Head and Neck Surgery.

Racial differences in fatal coronary heart disease associated with risk factor burden

Despite treatment advances for coronary heart disease over the past 20 years, black men and women still have twice the risk of fatal coronary heart disease compared with white men and women, according to a study from the University of Alabama at Birmingham appearing in the Nov. 7, 2012 issue of the Journal of the American Medical Association.

Comprehensive review article on baroreflex sensitivity after SCI

Spinal cord injury (SCI) can disrupt the body's sensitive signaling mechanisms that control blood pressure, breathing, and oxygen delivery to the heart and other organs during changes in body position. Cardiovascular (CV) disease is a leading cause of illness and death following SCI, and changes in baroreflex sensitivity-the body's ability to detect and respond to changes in blood pressure-may be predictive of a CV event.

Probiotic formulation can reduce cholesterol esters

Two daily doses of a probiotic lowered key cholesterol-bearing molecules in the blood as well as "bad" and total cholesterol, in a study presented at the American Heart Association's Scientific Sessions 2012.

ECG analysis may predict risk of death from all causes

Research by Johns Hopkins cardiologists suggests that electrocardiograms (ECGs), which are widely used tests to assess the heart’s electrical activity, may have a greater and more profound future role in predicting the risk of death from any cause, not just heart problems.

Low-dose aspirin effective at preventing serious blood clots

Low-dose aspirin is a cheap and effective way to prevent potentially deadly blood clots in the leg or the lungs in patients who have had a previous blood clot a new study shows.

New tool helps prevent hospital readmission among heart attack patients

Some heart attack patients end up back in the hospital just weeks after going home. It can happen for a variety of reasons, but doctors haven't had a reliable way to predict which patients will return - until now.

Midwest symposium to discuss new concepts for tissue-specific regenerative medicine

Hoxworth Blood Center, the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center will host the Midwest Symposium on New Concepts For Tissue-Specific Regenerative Medicine, Nov 17-18, 2012, in Rieveschl Auditorium of the Vontz Center for Molecular Studies.

Peptide-enhanced tomatoes reduce atherosclerosis in mice

For the first time, genetically engineered tomato plants produced a peptide that mimics the actions of good cholesterol when eaten, researchers reported at the American Heart Association's Scientific Sessions 2012.

Patients with diabetes, multi-vessel coronary artery disease can benefit from bypass surgery

An international, clinical research trial has shown that patients with diabetes whose multi-vessel coronary artery disease is treated with bypass surgery live longer and are less likely to suffer severe complications like heart attacks than those who undergo angioplasty.

Lifetime risks for total CVD are high regardless of index age

Even in men and women with an optimal cardiovascular disease (CVD) risk factor profile, the lifetime risk estimate for CVD is greater than 30 percent, and is more than 50 percent for men and women overall, according to a study appearing in November 7 issue of JAMA, a theme issue on cardiovascular disease.

Latinos, Hispanics in the U.S. more likely to develop major cardiovascular diseases

Hispanics and Latinos living in the U.S. are highly likely to have several major cardiovascular disease risk factors, such as high cholesterol, high blood pressure, obesity, diabetes, and smoking, according to a new, large-scale study. Risks vary among the diverse Hispanic/Latino groups, but individuals who were born in the U.S. are more likely to have multiple risk factors.

Home monitoring may not improve blood pressure control in patients with hypertension and stroke

Home blood pressure monitoring may help patients with hypertension and stroke but did not improve blood pressure control for patients who had normal blood pressure at the start or those with disabilities, according to a randomized controlled trial published in CMAJ (Canadian Medical Association Journal).
