Bioartificial kidney under study at MCG

... "Anywhere from 50 to 70 percent of those patients die and over the past 20 years, despite dialysis, that has not changed much." He hopes the new device, developed by Dr. H. David Humes at the University of Michigan, can help turn the tide for some patients by more closely mimicking the many important f...

Protein discovery could unlock the secret to better TB treatment

...istant TB. In England and Wales around 400 people die each year from the disease. The top challenge for TB control in the European region is multidrug-resistant TB (MDR-TB). Eight per cent of the bacteria causing TB in patients are resistant to one or more drugs and one per cent show multidrug resistanc...

Recent breakthroughs in common adult leukemia highlighted in New England Journal of Medicine

...patients whose disease follows this course usually die with the disease, not because of it. CLL may also follow a more aggressive course. In these cases, patients do require chemotherapy and have a lifespan of only about six to eight years after diagnosis despite treatment. Scientists, including Drs. Ch...

Scientists detect probable genetic cause of some Parkinson's disease cases

...hyear. The disease occurs when certain nerve cells die or becomeimpaired and can no longer produce dopamine, a brain signaling chemical(neurotransmitter). Without it, individuals can develop tremor ortrembling in hands, arms, legs, jaw, and face; rigidity or stiffness ofthe limbs and trunk; bradykinesia,...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...ted muscular disorder called Pompe disease usually die before they reach the age of two. The researchers also said their approach of targeting corrective genes to muscles may have application in treating other muscular dystrophies. Patients with Pompe disease have a defect in a key enzyme that converts ...

Taking Aim With Nanoparticle PEBBLEs

...live less than four months without treatment; rats die within about five days. When Kopelman's group treated rats with PEBBLEs that weren't even tailored to home in on cancer cells, the rats lived twice as long. With targeted PEBBLEs, some rats were still alive and active two months later, and MRI images...

Researchers discover molecule that causes secondary stroke

...l stroke develop vasospasm, and 40 percent of them die from it. Vasospasm, says neurology department researcher Joseph Clark, PhD, results from a buildup of toxins caused by bleeding from the initial stroke. "Normally the cerebral spinal fluid that envelopes the brain carries off wastes and exchanges th...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...lies, which have been studied closely for decades, die sooner from aging in a high-oxygen environment." Insects take in oxygen through spiracles -- tubes connected to openings in their sides. In their study, the researchers inserted fine tubes into the spiracles of a moth to measure not only how much ca...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

"The presence of growth hormone and IGF-1 is necessary for maintenance of cognitive function and prevention of cartilage degeneration," Sonntag and his colleagues reported in an article in Endocrinology, published on-line today. But th...

Research Gives Hope For Liver Damage

More womenin the UK now die of liver failure than do of cancer of the cervix."There has been a fourfold increase in the number of men aged 45-54dying of cirrhosis since 1970 and a threefold increase in women of thesame age group. Liver failure is also rapidly increasing in youn...

Simple drug has the potential to save many lives threatened by malaria

For those who do make it to hospital, half of deaths occur within 24 hours of admission. Conventional treatment, given by injection, is not possible ...

White blood cell waste disposal system plays critical regulatory role

Dying neutrophils are recognized and ingested by cells in the body tissues called phagocytes. Although the specific mechanisms that regulate the proper ratios of neutroph...

Neurofibromatosis gets its name from neurofibromas, the disfiguring and often painful tumors that grow along nerve coverings and form on or under the skin.
