Human stem cell treatment restores motor function in paralyzed rats

... Paraplegia from spinal cord ischemia is a serious complication that occurs in 20 to 40 percent of patients undergoing a surgical process called aortic cross-clamping. When the surgeon works on the aorta, a major blood vessel, to correct a potentially lethal aneurysm, blood flow from the heart must be tempora...

Drug-resistant bacterial infections serious complication after corrective eye surgery

...MRSA infectious keratitis is a potentially serious complication following refractive surgery. Healthcare workers may develop keratitis from microbes associated with nosocomial infection. In addition, surgeons should now be vigilant for community-acquired MRSA keratitis. All patients should be informed of the risk...

Twin studies reveal genetic components leading to cardiac and kidney disease

...rine is one sign of kidney disease, which can be a complication of diabetes. "Normally kidneys filter the blood to rid the body of accumulated toxins. In healthy kidneys, more than a million little ‘baskets?or ‘sieves?filter out the bad chemicals without leaking ‘good?cells or proteins," said O’Connor, adding...

Cholera pathogen reveals how bacteria generate energy to live

...on can be changed without affecting pH, which is a complication with protons. "It’s a very good system to understand this very basic mechanism charging this battery to create energy," she said. In order to learn how the enzyme works, researchers are trying to get an idea of its three-dimensional structure. "Th...

Molecules in blood foretell development of preeclampsia

...nt development of preeclampsia, a life-threatening complication of pregnancy, report a team of researchers from the National Institutes of Health and Beth Israel Deaconess Medical Center. The proteins, which interfere with the growth and function of blood vessels, also signal the development of high blood pressu...

SARS: No evidence that any of the treatments worked

...cially in those patients who developed a dangerous complication called acute respiratory distress syndrome. Researchers conducted a comprehensive search for information from research studies that fitted carefully pre-defined selection criteria. They found 54 SARS treatment studies, 15 in- vitro studies, and thr...

The biggest bug in gut discomfort

...ith compromised immune systems. A rare but serious complication of C. jejuni infection is the triggering of the autoimmune disorder, Guillain-Barré paralysis. Yale researchers now have some answers to one of the most basic puzzles surrounding C. jejuni infections. How could such a large bacteria gain access to...

Lack of key enzyme associated with development of rare tumor

...etailed clinical studies addressing this potential complication are currently lacking," they wrote. Dr. Stratakis and his colleagues are currently planning studies to determine if differences in the gene for PDE11A might influence an individual's cancer risk. ...

How bad is malaria anemia? It may depend on your genes

...ch children may be most susceptible to this lethal complication of malarial infection and to identify treatments targeted to them especially, the study's authors suggest. "This is important because in places where malaria is endemic, drug treatment resources are scarce," says the study's primary author, Michael...

A sweet solution for Alzheimer's disease?

...on to the vaccine," the researcher said. Another complication with previous attempts to treat Alzheimer's disease has been that some compounds--such as beta secretase inhibitors--cannot enter the brain easily, St George-Hyslop explained. Scyllo-inositol, on the other hand, readily passes through the blood-brain...

Novel therapy combinations gain ground in treating hepatitis

...e in accelerating liver failure, ordinarily a rare complication of viral hepatitis. Serum samples from 72 patients with proven hepatitis A or B that had progressed to liver failure were tested for APAP adducts, which are the toxic byproducts of acetaminophen liver damage, created when a chemical (in this case, ...

Mayo Clinic researchers challenge sepsis theory

...ns to critical care units and can be a significant complication of some heart surgeries. The Mayo Clinic researchers believe current sepsis treatment isn't more effective because the theory of sepsis is too narrow. Current treatments don't target all causes of sepsis syndrome -- only the bacterial poison cause --...

Researchers develop portable 'vein finder' for faster, more accurate injections

...s Jim Larsen, a research engineer in EOSL. Another complication is that only a small amount of energy, about 1/10,000 of transmitted waves, scatters off the vein. "So you're limited in how much energy you can put in and how much you can pick up," he adds. "Cost, size and power issues restrict us to using a sing...

Defective immune system response to smallpox vaccine detailed in new study

Eczema vaccinatum occurs almost exclusively in people who have a history of atopic dermatitis, a common, non-contagious skin disorder also known as eczema. "This new research, the first to be published by Atopic Dermatitis a...

Unique equine cataract surgery offered on routine basis

...use previously attempted procedures carried a high complication rate. To achieve the best results, the surgeons borrowed several techniques regularly used in human cataract removal. The team adapted a human phacoemulsification machine for equine use, which breaks up a cataract through ultrasound. They combin...

Common alternative treatment for liver disease is found to be ineffective

Scientists use gene transfer technology and common virus to block neuropathic pain

.... It's called neuropathic pain, and it's a common complication of many diseases and medical conditions, especially diabetes. Drugs have little effect on this type of pain, which is caused by damage to sensory neurons that transmit pain, temperature and touch signals to and from the brain. Now, scientists at the...
