Medicated stents lower likelihood of heart attacks in cardiac patients

Researchers at Cleveland Clinic have discovered that cardiac patients receiving medicated stents - a procedure that occurs often when blood vessels are blocked - have a lower likelihood of suffering heart attacks or developing new blockages in the vessel downstream from the stent.

Differences in lifestyle, tumor genetics linked to head and neck cancer in African Americans

Why are African Americans more likely than Caucasians to be not only diagnosed with head and neck cancer, but also die from the disease? While the answer isn't a simple one, differences in lifestyle, access to care and tumor genetics may, in part, be to blame, according to a new study from Henry Ford Hospital.

Researchers may have solved 100-year-old puzzle to safely open and close the blood-brain barrier

Cornell University researchers may have solved a 100-year puzzle: How to safely open and close the blood-brain barrier so that therapies to treat Alzheimer's disease, multiple sclerosis and cancers of the central nervous system might effectively be delivered.

Researchers combine 3-D printing technology and multiphoton polymerization to develop artificial blood vessels

Researchers have been working at growing tissue and organs in the laboratory for a long time. These days, tissue engineering enables us to build up artificial tissue, although science still hasn't been successful with larger organs. Now, researchers at Fraunhofer are applying new techniques and materials to come up with artificial blood vessels in their BioRap project that will be able to supply artificial tissue and maybe even complex organs in future.

Lignans lower risk of death in women with breast cancer

Phytoestrogens are plant compounds which, in the human body, can attach to the receptors for the female sexual hormone estrogen and which are taken in with our daily diet. A number of findings have attributed a cancer protective effect to these plant hormones. At DKFZ, a team headed by Prof. Dr. Jenny Chang-Claude summarized the results of several studies in a meta-analysis last year and showed that a diet rich in phytoestrogens lowers the risk of developing breast cancer after menopause.

Crocus plant to provide a tumor killing “smart bomb”

According to the latest research, a drug derived from plant extracts could wipe out tumors in a single treatment with minimal side effects. Scientists have turned a chemical found in crocuses into a ‘smart bomb’ that targets cancerous tumors. The advantage is that healthy tissue is unharmed, reducing the odds of debilitating side effects. And unlike other side effect-free drugs, it is able to kill off more than one type of the disease, including breast, prostate, lung and bowel cancer. Potentially, all solid tumours could be vulnerable to drugs developed this way, meaning it could be used against all but blood cancers.

Scientists identify 28 blood pressure-associated genetic variants

A new report from scientists at Massachusetts General Hospital (MGH) and their colleagues in centers around the world finds that common variants in 28 regions of DNA are associated with blood pressure in human patients.

New method for making synthetic collagen

In a significant advance for cosmetic and reconstructive medicine, scientists at Rice University have unveiled a new method for making synthetic collagen. The new material, which forms from a liquid in as little as an hour, has many of the properties of natural collagen and may prove useful as a scaffold for regenerating new tissues and organs from stem cells.

Stents for blocked brain arteries may not be as successful in prolonging survival as believed: Study

A study out this Wednesday says that insertion of an artery-opening device called a stent into the brain to improve blood flow to prevent a second stroke may do more harm than managing high-risk patients with drugs and lifestyle changes. Blocked brain arteries caused by the build-up of fatty deposits called plaque account for more than 50,000 of the 795,000 strokes occurring in the United States each year. Stroke is the fourth-leading cause of death and a leading cause of disability in the United States.

Exercise, intervention may help individuals with peripheral arterial disease

Peripheral arterial disease, or PAD, is a common condition affecting 12-20 percent of Americans age 65 and older that may be a signal of future heart attack and stroke-and many with the disease may be unaware they have it, says the Society of Interventional Radiology.

Researchers rethink fenretinide for prevention of oral cancer

Scientists on the cutting edge of biomedical research know that research is a process - a combination of successes and failures that inform the next step forward. However, for some researchers at The Ohio State University progress means taking a step back. Supported by the Ohio State University Center for Clinical and Translational Science (CCTS), these scientists are using failed and forgotten research to uncover future treatments for major health conditions as diverse as oral cancer and stroke.

Australia’s Mesoblast receives nod to start first European trial of allogeneic stem cell treatment for heart attacks

Global regenerative medicine company, Mesoblast Limited, (ASX: MSB), today announced that it had received clearance from the European Medicines Agency (EMA) to begin a 225-patient multi-center Phase 2 clinical trial in Europe for its lead cardiovascular product Revascor™ in conjunction with angioplasty and stent procedures to prevent heart failure after a major heart attack. Revascor™ is an allogeneic, or “off-the-shelf”, adult stem cell product derived from Mesoblast's proprietary Mesenchymal Precursor Cell (MPC) platform technology which is being developed for use in a range of cardiovascular diseases including congestive heart failure, chronic angina, and heart attacks (acute myocardial infarction).

Blocked blood vessels linked to familiar signs of aging

Many common signs of aging, such as shaking hands, stooped posture and walking slower, may be due to tiny blocked vessels in the brain that can't be detected by current technology.

Neutrophils linked to growth and spread of cancer

Scripps Research Professor James Quigley, Staff Scientist Elena Deryugina, and colleagues had previously demonstrated that white blood cells known as neutrophils—bone marrow-derived cells that function as "first responders" at sites of acute inflammation—promote the growth of new blood vessels in normal, healthy tissue.
