New medical breakthrough by Bioheart for treatment of patients with heart disorders

Bioheart, Inc. offers yet another medical breakthrough with the next-level stem cell treatment for cardiac patients. The stem cells aid in limiting damage due to a cardiac event and promote angiogenesis or formation of new blood vessels.

Coupling electrosurgery with mass spectrometry for real-time identification of tumor tissues

Instead of the classic scalpel, surgeons can also operate with an electroscalpel. A significant advantage to this technique is that while a cut is being made, blood vessels are closed off and hemorrhaging eliminated. Now another advantage may be added as well: a German-Hungarian research team has developed a mass-spectrometry-based technique by which tissues can be analyzed during a surgical procedure.

Transient ischemic attack can trigger stroke

One out of every eight strokes is preceded by a "warning stroke," which is a transient ischemic attack (TIA) or mild stroke, according to research published in the September 29, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Blood vessels in the retina may help predict risk of heart attack or stroke

For centuries eyes have been seen as windows to the soul. But medical researchers now believe the eyes may also offer vital clues to your risk of heart disease and stroke.

Increasing insulin levels can aid muscle building in the elderly

Recently, scientists have recognized that loss of responsiveness to insulin plays a major role in the loss of physical strength that occurs as people grow older. Now, University of Texas Medical Branch at Galveston researchers have demonstrated that by increasing insulin levels above the normal range in elderly test subjects, they can restore the impaired muscle-building process responsible for age-related physical weakness.

$1.3 million fund awarded to WPI for ongoing life sciences research

Researchers at Worcester Polytechnic Institute's (WPI) Life Sciences and Bioengineering Center at Gateway Park have received a total of $1.3 million in new awards from the National Institutes of Health (NIH) and the National Science Foundation (NSF) to fund ongoing research in several areas of the life sciences, including a study of the bacterium that causes tuberculosis, work aimed at using adult stem cells to repair damaged hearts, and a project that seeks to create engineered blood vessels.

Misregulation of SPAK protein may contribute to B-cell lymphoma development

A group led by Dr. Michael Teitell at UCLA has demonstrated that misregulation of the protein SPAK may contribute to B-cell lymphoma development. Their report can be found in the October 2009 issue of the American Journal of Pathology.

Acetaminophen can prevent age-related problems

Recent studies conducted by Dr. Eric Blough and his colleagues at Marshall University have shown that use of the common pain reliever acetaminophen may help prevent age-associated muscle loss and other conditions.

Sorafenib with chemotherapy for breast cancer patients had a 74% percent improvement in the time they lived

One of the first of a series of trials to investigate the use of sorafenib - a targeted anti-cancer drug - for the treatment of advanced breast cancer has found that if it is combined with the chemotherapy drug, capecitabine, it makes a significant difference to the time women live without their disease worsening.

Melanoma patients could be spared from unnecessary surgery

Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival.

Preventing nerve cell death in diabetics

Dennis Paul, PhD, Associate Professor of Pharmacology, and Harry Gould, MD, PhD, the Tom Benson Professor of Neurology at LSU Health Sciences Center New Orleans, have been awarded one of two scientific research grants made in 2009 by The Neuropathy Association. The $80,000 grant will fund research to learn how to prevent nerve cell death in people with uncontrolled or untreated diabetes resulting in neuropathy.

Study reveals effectiveness of targeted heat therapy in addition to chemotherapy

Patients with soft-tissue sarcomas at high risk of spreading were 30% more likely to be alive and cancer free almost three years after starting treatment if their tumours were heated at the time they received chemotherapy, according to new research. The finding bolsters the case for intensifying exploration of the strategy in other types of cancer.

Technique to reduce stroke in cardiac surgery patients

Sequoia Hospital announced today that they are one of only two hospital participant abstracts selected for oral presentation at the Society of Thoracic Surgeons Advances in Outcomes and Quality national conference held this week in San Diego, California. "Separated Cerebral and Corporeal Perfusion Reduces Stroke Risk in Cardiac Surgery Patients with Mobile Aortic Atheromata" will be presented by Audrey Fisher, MPH, Sequoia Hospital Manager of Cardiovascular Quality & Outcomes. This new technique was developed to reduce strokes in cardiac surgery patients by isolating blood flow to the brain during cardiopulmonary bypass.

Blood vessels around the brain now converted into production/delivery systems

The blood brain barrier is generally considered an obstacle to delivering therapies from the bloodstream to the brain. However, University of Iowa researchers have discovered a way to turn the blood vessels surrounding brain cells into a production and delivery system for getting therapeutic molecules directly into brain cells.

New device for identifying eye conditions in infants

Tell-tale signs of a condition that can blind premature babies are being seen for the first time using a new handheld device in a study at Duke University Medical Center.

Mathematical model of an ischemic wound

Scientists expect a new mathematical model of chronic wound healing could replace intuition with clear guidance on how to test treatment strategies in tackling a major public-health problem.

Study reveals effectiveness of drug-eluting stents in treating chronic total occlusions

A multicenter study in Asia found drug-eluting stents effective with a low rate of acute complications in patients with chronic total occlusions (CTOs) undergoing PCI. Results of the study will be presented at the 21st annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

Study reveals microRNAs affect tumor progression

UCSF researchers have identified collections of tiny molecules known as microRNAs that affect distinct processes critical for the progression of cancer. The findings, they say, expand researchers' understanding of the important regulatory function of microRNAs in tumor biology and point to new directions for future study and potential treatments.
