Nanomedicine neither a cure-all nor a potential danger

Is the emerging field of nanomedicine a breathtaking technological revolution that promises remarkable new ways of diagnosing and treating diseases? Or does it portend the release of dangerous nanoparticles, nanorobots or nanoelectronic devices that will wreak havoc in the body? A new review of more than 500 studies on the topic concludes that neither scenario is likely. It appears in ACS' journal Molecular Pharmaceutics.

Breakthrough in loading gold nanorods into cells could lead to new cancer treatment

Rice University chemists have found a way to load more than 2 million tiny gold particles called nanorods into a single cancer cell. The breakthrough could speed development of cancer treatments that would use nanorods like tiny heating elements to cook tumors from the inside.

Flexible brain implant could treat epileptic seizures

Researchers funded by the National Institutes of Health have developed a flexible brain implant that could one day be used to treat epileptic seizures. In animal studies, the researchers used the device - a type of electrode array that conforms to the brain's surface - to take an unprecedented look at the brain activity underlying seizures.

Novel gene mutation may increase risk of inherited and sporadic cases of MM

A major international study has identified a novel gene mutation that appears to increase the risk of both inherited and sporadic cases of malignant melanoma, the most deadly form of skin cancer.

Vegetative patients could be contacted using simple, cheap and portable technique – EEG

Scientists from the UK and Belgium have found a way to communicate with brain damaged patients who appear to be in a vegetative state. Writing in The Lancet medical journal they describe how they measured electrical activity in the brain to detect consciousness. The technique, known as EEG or electroencephalogram, is painless and involves attaching electrodes to the head.

New technology can detect toxins in a person's breath

Breathing. Anyone reading this article is doing it right now. But what chemicals are we breathing in, and out? A group of Virginia Tech College of Engineering researchers has published a paper in the journal Environmental Science & Technology that details how to learn just that, using microelectromechanical systems to focus on toxins and everyday impurities that enter the body through the air we intake.

New technologies could aid in malignant melanoma diagnosis and therapy

Because the incidence of malignant melanoma is rising faster than any other cancer in the U.S., researchers at Moffitt Cancer Center in Tampa, Fla., and colleagues at Tampa-based Intezyne Technologies, Inc., Western Carolina University and the University of Arizona are working overtime to develop new technologies to aid in both malignant melanoma diagnosis and therapy.

New way to screen hirsutism among women

Examining the chin and upper and lower abdomen is a reliable, minimally invasive way to screen for excessive hair growth in women, a key indicator of too much male hormone, researchers report.

Scientists pinpoint central elements of cell division

Scientists at Warwick Medical School have uncovered the molecular process of how cells are by-passing the body's inbuilt 'health checkpoint' with cells that carry unequal numbers of chromosomes that have a higher risk of developing cancer.

Potential drug therapy for Hutchinson Gilford Progeria Syndrome

Researchers have identified a potential drug therapy for a premature ageing disease that affects children causing them to age up to eight times as fast as the usual rate.

Cranberry juice far better than extracts at fighting urinary tract infections

With scientific evidence now supporting the age-old wisdom that cranberries, whether in sauce or as juice, prevent urinary tract infections, people have wondered if there was an element of the berry that, if extracted and condensed, perhaps in pill form, would be as effective as drinking the juice or eating cranberry sauce. A new study from researchers at Worcester Polytechnic Institute helps to answer that question.

Research focuses on JQ1 molecule that tricks NUT midline carcinoma cancer cells

NUT midline carcinoma (NMC) is a cancer without a cure, and one that affects all age groups. NMC is a rapid-growth disease with an average survival time of four and a half months after diagnosis, making the development of clinical trials for potential therapies or cures for this cancer difficult, to say the least.

New potential leukemia therapy targets and kills cancer cells

A new potential leukemia therapy targets only cancer cells, while leaving healthy cells alone. Many current chemotherapy treatments affect cancer cells and healthy cells, causing significant side effects, such as fatigue, hair loss, nausea, anxiety and depression.

HMS, EPFL to collaborate on 6 pioneering neuroengineering projects

Two of the world's leading universities are joining forces to combine neuroscience and engineering in order to alleviate human suffering caused by such neurological disabilities as paralysis and deafness. Scientists, engineers, and clinicians at Harvard Medical School (HMS) and Ecole Polytechnique F-d-rale de Lausanne (EPFL) will collaborate on six pioneering neuroengineering projects made possible thanks to a $3.6 million grant from the Bertarelli Foundation.

Clues into how gene defects may cause ARPKD in babies

Babies born with autosomal recessive polycystic kidney disease (ARPKD) often develop kidney failure because they have very large kidneys filled with tiny cysts. Even with excellent medical care, about 30% die shortly after birth. New research now provides clues into how gene defects may cause this condition, which occurs in 1 out of 20,000 newborns.
