Penn surgeons perform first bilateral hand transplantation

For the first time in the Delaware Valley Region, a patient has undergone a complex and intricate bilateral hand transplant that could significantly enhance the quality-of-life for persons with multiple limb loss.

Massive clotting can destroy placenta and cause miscarriages

Researchers at St. Michael's Hospital have identified a potential new cause for unexplained miscarriages in mice.

Knife-edge scanning microscopy rapidly maps new blood vessels in organs

Like normal tissue, tumors thrive on nutrients carried to them by the blood stream. The rapid growth of new blood vessels is a hallmark of cancer, and studies have shown that preventing blood vessel growth can keep tumors from growing, too. To better understand the relationship between cancer and the vascular system, researchers would like to make detailed maps of the complete network of blood vessels in organs. Unfortunately, the current mapping process is time-consuming: using conventional methods, mapping a one-centimeter block of tissue can take months.

Stanford Hospital uses new device to treat brain aneurysm

If Barbara Maluo's brain aneurysm had been discovered a few months ago, she would have had few viable treatment options. She was one of the 10 to 15 percent of brain aneurysm patients diagnosed each year with aneurysms so large and wide that they cannot be reliably treated using conventional methods of treatment.

Infiltration of white blood cells into blood vessels may explain high blood pressure in pregnancy

Virginia Commonwealth University School of Medicine researchers have discovered that the infiltration of white blood cells into an expectant mother's blood vessels may explain high blood pressure in pregnancy.

Fat cells play a major role in mediating ovarian cancer metastasis

A large pad of fat cells that extends from the stomach and covers the intestines provides nutrients that promote the spread and growth of ovarian cancer, reports a research team based at the University of Chicago in the journal Nature Medicine, published online October 30th, 2011.

'Heroes of Hope Race for Brain Tumor Research' event to be held on Nov. 6

Veronica Cappalonga, 28, knows a lot about living with cancer. Diagnosed at age 6 with leukemia and at 22 with a malignant brain tumor, the Los Angeles (Mar Vista area) resident will walk in the Nov. 6 Heroes of Hope Race for Brain Tumor Research - not only to help fundraise, but also to show that survivors can fight these diseases with dignity.

Researchers uncover biochemical signals that trigger generation of new lung alveoli

Researchers at Weill Cornell Medical College say they have taken an important step forward in their quest to "turn on" lung regeneration -- an advance that could effectively treat millions of people suffering from respiratory disorders.

Platform approach to chemically incorporate homing receptors onto surface of cells

Stem cell therapies hold enormous potential to address some of the most tragic illnesses, diseases, and tissue defects world-wide. However, the inability to target cells to tissues of interest poses a significant barrier to effective cell therapy.

Patients with ANCA-associated vasculitis harbor Flt1 protein that blocks blood vessel repair

In some kidney diseases, patients have high blood levels of a protein that blocks blood vessel repair, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology.

Novel technique saves Gulf War veteran's forearm

A plastic surgeon at UT Southwestern Medical Center recently used a novel technique to save the arm of a Gulf War veteran who was rushed to Parkland Memorial Hospital after a horrific accident.

Novel stem cells method may eliminate need for antirejection drugs in transplants

Surgical researchers at the University of Washington, Seattle, have pioneered a method using stem cells that may one day eliminate the need for antirejection drugs in transplants. Primary investigator David Mathes, MD, FACS, and his research fellow Jeff Chang, MD, MS, presented their findings today at the 2011 Clinical Congress of the American College Surgeons.

Fasudil drug shows promise against cerebral cavernous malformation

A drug treatment has been proven to prevent lesions from cerebral cavernous malformation — a brain blood vessel abnormality that can cause bleeding, epilepsy and stroke — for the first time in a new study.

Special team care reduces cumulated stroke risk after transient ischaemic attacks

Patients who had a transient ischaemic attack (TIA), sometimes referred to as a "mini stroke", were much less likely to experience further vascular events in the first year if their care was co-ordinated by a special hospital team. That is the key finding from a study published in the November issue of the European Journal of Neurology.

Nipple sparing mastectomy safe and effective option for breast cancer treatment

A new study suggests some women needing a lumpectomy or mastectomy to treat their breast cancer have another potential option that is safe and effective, say researchers at Georgetown. They say the procedure known as a nipple sparing mastectomy is also a viable surgical option for women who choose to have their breasts removed because of their increased risk of developing the disease.

Novel scarless surgery effectively removes skull base tumors

A technique developed by Johns Hopkins surgeons is providing a new route to get to and remove tumors buried at the base of the skull: through the natural hole behind the molars, above the jawbone and beneath the cheekbone.

Simple blood test could quantify a smoker's lung toxicity and danger of heart disease

A simple blood test could someday quantify a smoker's lung toxicity and danger of heart disease, researchers at UT Southwestern Medical Center have found.

Mesoblast cleared to begin first phase 2 clinical trial for wet AMD

Regenerative medicine company Mesoblast Limited (ASX: MSB) today announced that it has received regulatory clearance from the Singapore Health Sciences Authority (HSA) to commence the first Phase 2 trial of its proprietary allogeneic (off-the-shelf) adult stem cell therapy for patients with proliferation of leaky blood vessels in the eyes – neovascular (“wet”) Age-related Macular Degeneration (AMD).
