Non-invasive "optical biopsy" to detect breast cancer

Most biopsies following mammograms reveal benign abnormalities, not cancer.

Scientists identify new behavioral traits of immune cells; findings may help in understanding complex diseases

In diseases such as multiple sclerosis, cells of the immune system infiltrate the brain tissue, where they cause immense damage. For many years, it was an enigma as to how these cells can escape from the bloodstream. This is no trivial feat, given that specialized blood vessels act as a barrier between the nervous system and the bloodstream.

Nanoparticles may cause DNA damage across a cellular barrier

Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The nanoparticles did not cause the damage by passing through the barrier, but generated signalling molecules within the barrier cells that were then transmitted to cause damage in cells the other side of the barrier.

Scientists identify a novel cellular source of atrial fibrillation

While studying how the heart is formed, scientists at the University of Pennsylvania School of Medicine serendipitously found a novel cellular source of atrial fibrillation (AF), the most common type of abnormal heart beat.

PAH patients face life-threatening risks from medication errors

Pulmonary arterial hypertension (PAH) patients using infused drugs have suffered serious injury or in some cases died from medication errors in hospitals and other inpatient settings, according to a peer-reviewed study by Accredo Health Group and several university hospitals that surveyed doctors, nurses and pharmacists.

Reduced VEGF can lead to degeneration of retina

Scientists at Schepens Eye Research Institute have found that when the eye is missing a diffusible form of vascular endothelial growth factor (VEGF), i.e. one that when secreted can reach other cells at a distance, the retina shows defects similar to "dry" macular degeneration, also called geographic atrophy (GA).

Inner sense of cardiovascular state relies on two independent pathways, shows study

A new study suggests that the inner sense of our cardiovascular state, our "interoceptive awareness" of the heart pounding, relies on two independent pathways, contrary to what had been asserted by prominent researchers.

Blood vessels good indicators of prostate cancer behavior

A diagnosis of prostate cancer raises the question for patients and their physicians as to how the tumor will behave. Will it grow quickly and aggressively and require continuous treatment, or slowly, allowing therapy and its risks to be safely delayed?

Health Canada approves the marketing of BioMimetic Therapeutics' Augment Bone Graft

BioMimetic Therapeutics, Inc. announced today that it has received approval from Health Canada to begin the marketing of its lead orthopedic product, Augment™ Bone Graft, as an alternative to the use of autograft in midfoot, hindfoot and ankle fusion indications in Canada.

$3.9 million Challenge grant for Thomas Jefferson researchers

Four researchers from Thomas Jefferson University have received $3.9 million in Challenge grant funds as part of the American Recovery and Reinvestment Act.

Smokers with systemic lupus erythematosus at greater risk of skin damage and rashes

As if there weren't enough reasons to stop smoking, a team of researchers at the Research Institute of the McGill University Health Centre (RI-MUHC) have just found another. A study led by Dr. Christian A Pineau, Co-Director of the Lupus and Vasculitis clinic at the MUHC, has clearly linked skin damage and rashes to smoking in people with systemic lupus erythematosus (SLE). The study was published in a recent issue of the Journal of Rheumatology.

Medico's Hirata to distribute Broncus Technologies' LungPoint system and Yield catheters in Japan

Broncus Technologies, Inc., a medical device company focused on developing and commercializing innovative solutions for lung diseases, announced today at the American College of Chest Physicians CHEST 2009 meeting that it has entered into an exclusive agreement with Medico's Hirata as the sole distributor of their LungPoint system and Yield catheters in Japan.

Combination of inhibitor and antioxidants may help prevent diabetes complications

In diabetes patients, high blood glucose levels can end up killing certain cells in the eyes and kidneys, which is why diabetes is the leading cause of adult blindness and of kidney failure. Years ago, scientists identified one main route for this destruction—high glucose produces oxidative stress through the NF-kB molecular pathway—but success has been elusive for drugs targeting that pathway.

Study: Charcoal lessens atherosclerotic lesions in mice with kidney damage

Charcoal may provide a new approach to managing the high rate of heart disease in patients with advanced kidney disease, according to preliminary research being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, CA.

Johns Hopkins researchers find life in blood-starved retinas; shed light on vision loss

Like all tissues in the body, the eye needs a healthy blood supply to function properly. Poorly developed blood vessels can lead to visual impairment or even blindness. While many of the molecules involved in guiding the development of the intricate blood vessel architecture are known, only now are we learning how these molecules work and how they might affect sight.
