Heart Disease-on-a-chip

May 12, 2014 1:52 pm | News | Comments

Harvard scientists have merged stem cell and “organ-on-a-chip” technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease. The research appears to be a big step forward for personalized medicine, because it is working proof that a chunk of tissue containing a patient’s specific genetic disorder can be replicated in the laboratory.

'Bad' Cholesterol Helps Cancer Spread

May 7, 2014 12:48 pm | News | Comments

In a world-first, researchers have discovered one of the main reasons behind why cancer spreads throughout the body: the help of "bad" cholesterol. The research found that LDL regulates the machinery that controls cell migration.       

Novel Antioxidant Makes Old Arteries Seem Young Again

May 6, 2014 2:18 pm | News | Comments

‘Remarkable’ Therapy Makes Old Mice Young, May Hit Clinic This Year

May 5, 2014 1:05 pm | by Cynthia Fox | Articles | Comments

A futuristic anti-aging approach, variously described and utilized by three different Harvard and Stanford groups this week, may hit the clinic by year’s end. The research all began with “heterochronic parabiosis.” That is, old mice were hooked up to young mice via their circulatory systems— and experienced tissue rejuvenation. 

Stem Cells Regenerate Heart Muscle in Primates

May 1, 2014 1:24 pm | Videos | Comments

Stem cell therapy can regenerate heart muscle in primates, according to a new study. The scientists on this and related projects are seeking way to repair hearts weakened by myocardial infarctions.               

Potentially Powerful Tool for Treating Damaged Hearts

April 30, 2014 1:43 pm | News | Comments

A type of cell that builds mouse hearts can renew itself, researchers report. They say the discovery, which likely applies to such cells in humans as well, may pave the way to using them to repair hearts damaged by disease— or even grow new heart tissue for transplantation.

Secrets Behind Health Benefits of Wine Revealed

April 29, 2014 12:22 pm | News | Comments

Scientists have identified one of the molecular pathways that resveratrol, the component of grapes and red wine associated with health benefits, uses to achieve its beneficial action.                   

Dipping Blood Sugars Cause Surprisingly Irregular Heart Rhythms in Diabetics

April 28, 2014 1:54 pm | News | Comments

Dangerous overnight blood sugar levels often go undetected and cause prolonged periods of heart rhythm disturbances in older patients with Type 2 diabetes and associated heart problems, new research reveals. The findings could offer  clues to the mechanism by which low blood sugar levels could contribute to life-threatening changes in heart rhythm.

‘Junk’ Genome Regions Linked to Heart Failure

April 25, 2014 2:27 pm | News | Comments

Large sections of the genome that were once referred to as “junk” DNA have been linked to human heart failure, according to new research. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn’t code for proteins.

Statins May Lead Some Patients to Pig Out

April 24, 2014 9:20 pm | by Lindsey Tanner - AP Medical Writer | News | Comments

Ten years of U.S. data suggest that calorie and fat intake increased among statin users during the decade, an indication that many patients might be abandoning heart-healthy lifestyles and assuming that drugs alone will do the trick, the study authors said.

Half-Billion-Year-Old Heart Found More Complex than Today’s

April 24, 2014 3:01 pm | by Cynthia Fox | Articles | Comments

520 million years ago, the first known animal heart, the heart of an ancient shrimp, was formed. Now, it, and its vascular system, have been found to be more complex than that of modern shrimp, researchers report.

Boring Cells Could Hold the Key to Heart Disease

April 24, 2014 1:47 pm | News | Comments

Fibroblasts could offer an alternative to heart transplants for patients with heart disease. Researchers found that the heart cell fibroblast is a close relative to a cardiomyocyte, the cell responsible for a healthy beating heart.      

Ultrasound Device May Help Detect Risk for Heart Attack, Stroke

April 24, 2014 1:31 pm | News | Comments

Researchers have developed an ultrasound device that could help identify arterial plaque that is at high risk of breaking off and causing heart attack or stroke.                         

Scientists Alter Fat Metabolism in Animals to Prevent Heart Disease

April 23, 2014 12:28 pm | News | Comments

Working with mice and rabbits, scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.

CT Measures Potentially Dangerous Arterial Plaque in Diabetic Patients

April 22, 2014 3:04 pm | News | Comments

Imaging of the coronary arteries with computed tomography angiography provides an accurate assessment of arterial plaque and could have a dramatic impact on the management of diabetic patients who face a high risk of heart attacks and other cardiovascular events, according to a new study.

Lab Turns Skin Cells into Human Airway Tissue

April 22, 2014 12:25 pm | News | Comments

Using reprogrammed skin cells, researchers have for the first time used stem cell techniques to grow fully functional assemblies of the cells that line airways leading to the lungs.                    

Watermelon Could Lower Blood Pressure

April 3, 2014 12:00 pm | News | Comments

Be sure to pick up a watermelon—or two—at your local grocery store. It could save your life. A new study found that watermelon could significantly reduce blood pressure in overweight individuals both at rest and while under stress.

Early Cardiac Risks Linked to Worse Cognitive Function in Middle Age

April 1, 2014 1:39 pm | News | Comments

Young adults with such cardiac risk factors as high blood pressure and elevated glucose levels have significantly worse cognitive function in middle age, according to a new study by dementia researchers at UC San Francisco. The findings bolster the view that diseases like Alzheimer’s develop over an individual’s lifespan and may be set in motion early in life.

Relaxed Blood Pressure Guidelines Cut Millions from Needing Medication

March 31, 2014 2:20 pm | News | Comments

New guidelines that ease the recommended blood pressure could result in 5.8 million U.S. adults no longer needing hypertension medication. The findings are the first peer-reviewed analysis to quantify the impact of guidelines announced in February by the Eighth Joint National Committee. In a divisive move, the committee relaxed the blood pressure goal in adults 60 years and older to 150/90, instead of the previous goal of 140/90.

Newly Designed Gel Allows for Targeted Therapy After Heart Attack

March 31, 2014 1:25 pm | News | Comments

Combating the tissue degrading enzymes that cause lasting damage following a heart attack is tricky. Each patient responds to a heart attack differently and damage can vary from one part of the heart muscle to another, but existing treatments can’t be fine-tuned to deal with this variation. Penn researchers have developed a way to address this problem via a material that can be applied directly to the damaged heart tissue.

Married People Less Likely to Have Cardiovascular Problems
