Currently, ischemic stroke patients may be treated with tPA, the only FDA-approved stroke treatment available, but must receive treatment within three hours from the time the stroke initially occurs. As a result...

Healing honey: The sweet evidence revealed

... Extremity Wounds summarizes the data. Scientists performed 22 trials involving 2,062 patients treated with honey, as well as an additional 16 trials that were performed on experimental animals. Honey was found to be beneficial as a wound dressing in the following ways:...

Secrets of the sea yield stronger artificial bone

...lacement and nearly 300,000 knee replacements were performed in 2000, according to the National Center for Health Statistics. These numbers are expected to swell in the future as baby boomers age. Because of the pressing need for longer-lasting artificial bone, researchers like Tomsia have developed materials...

A case of mistaken molecular identity

... that under bright conditions, the Chagas patients performed comparably to 50 healthy control individuals. But in the dark, 37 of 45 (82 percent) Chagas patients had trouble seeing with at least one eye, and 19 of 45 (42 percent) had trouble with both eyes. Matsumoto then approached Paveto, and both contacted ...

Inflammation and drugs to control this activity studied in a variety of tumors sites

.... The researchers analyzed 84 subsequent biopsies performed within five years in patients who had initially shown chronic prostate inflammation. In the follow up, 29 new cancer cases were diagnosed: six occurred in patients in whom initial biopsies showed only chronic inflammation, 15 in patients with initial...
