UF Launches Project to Bridge the Regeneration Gap

...back on in people." Recently, studies have shown humans possess some of the same genes and communication pathways used by some of nature's most remarkably regenerative animals. Already, UF McKnight Brain Institute scientists have discovered more than 100 genes associated with all major human neurological...

Patients Buy Untried Cancer Drug On Web

...e of tumors in rats. But it has not been tested in humans so far. Understandably, terminally sick patients do not want to wait for the research in humans and it has been reported that around two hundred patients worldwide have bought this drug over the n...

Higher Trans Fat Levels in Blood Associated With Elevated Risk of Heart Disease

...n blood samples from the study population. Because humans cannot synthesize trans fatty acids, the amount of trans fat in red blood cells is an excellent biomarker of trans fat intake,” said senior author Frank Hu, associate professor of nutrition and epidemiology at HSPH. Clinical trials have shown that ...

Now Scientists Create a Sheep That's 15% Human

... prospect of animal organs being transplanted into humans one step closer. Professor Esmail Zanjani, of the University of Nevada, has spent seven years and ￡5 million perfecting the technique, which involves injecting adult human cells into a sheep's fetus. He has already created a sheep liver, which ...

Estradiol Guards Against Osteoporosis

...athway by which estradiol, the primary estrogen in humans maintains bone density. This function is significant as it aids in avoiding osteoporosis. // It is well known that estrogen is essential for healthy bone, and that when the production of estrogen is reduced, as occurs normally in postmenopausal wome...

A New Pathway To Deal With Sleeping Sickness

...zi and Chagas disease. Sleeping sickness affects humans and livestock, and is endemic in sub-Saharan Africa where it is estimated to affect as many as 70,000 people. Leishmaniasis is estimated to affect millions of individuals throughout the world, and can lead to skin lesions, tissue damage, fever, blind...

Swell Gel May Bring Respite From Back Pain

...properties. This result could be extrapolated to humans also where they can get back their mobility and flexibility after getting spinal injections. This process is said to be better when compared to spinal fusions which is a surgical procedure where the recovery period is long and there is a loss of mobi...

John Oxford, scientific director of Retroscreen Virology Ltd and professor of virology at UK-based Queen Mary's School of Medicine and Dentistry, said the adjuvant "looks to be a most interesting ...

Drug for Blood Pressure also Treats Lung Cancer

...hieved through treatment were similar to levels in humans being treated with an ACE inhibitor. 'The study may explain the molecular mechanism for a decreased risk of lung cancers in patients with high blood pressure taking ACE inhibitors,' said Tallant. The researchers believe that angiotensin-(1-7) re...

Caution Urged on Biologic Drugs

...generic biologic manufacturers test their drugs in humans before approval. Hatch also supports establishing patient registries to track side effects that may not occur until years after patients start using a product. “What we need to do is keep working to get the best legislation,” Hatch said.

Bacterium Could Treat PCBs Without the Need for Dredging

...the anaerobic bacteria thrive on the PCBs, much as humans thrive on oxygen. The microbes replace the chlorines on the PCBs with hydrogen, which fuels their growth and begins the PCB degradation process. The discovery of the Dhc bacteria’s unique abilities could one day alter the way we treat PCB contamina...
