Human stem cell treatment restores motor function in paralyzed rats

...archers believe that the therapy may eventually be proven even more effective in human patients, who would be able to receive physical therapy once treated. “Physical therapy may accelerate integration of the grafted stem cells and enhance their therapeutic benefit,” Johe said, adding that the goal is t...

HIVMA opposes The Gambia's unproven AIDS remedy

...ting is untested. It is highly unethical to stop a proven therapy to try an unproven one. We are extremely concerned that President Jammeh would recklessly experiment with his people’s lives." "We support the tireless efforts of African scientists, clinicians, and community health workers providing antir...

Scientists identify prion's infectious secret

...operties of prion biology that, up until now, have proven difficult to investigate," says Whitehead Member and MIT Professor of Biology Susan Lindquist, senior author on the paper, which will appear in the May 9 online issue of Nature. Proteins are the cell’s workhorses, and they need to fold into compl...

Warts vaccine -- 1 of many in pipeline

...ra (PA) Hospital. "The new treatment has so far proven safe, and we want to know if it improves the outcome after conventional therapy, which all patients also receive," Dr Jardine said. Trial researchers aim to use a tweaked version of Professor Frazer’s cervical cancer vaccine to treat genital wart...

DOE JGI sets 'gold standard' for metagenomic data analysis

...d for binning, but none of these on their own have proven satisfactory, Mavrommatis said. "What we propose in the paper is a way to evaluate the appropriateness and accuracy of the binning methods using the same datasets in order to set a gold standard, we have designed the reference-simulated metagenome."...

Studies force new view on biology of flavonoids

... happening in the human body." Research has now proven that flavonoids are poorly absorbed by the body, usually less than five percent, and most of what does get absorbed into the blood stream is rapidly metabolized in the intestines and liver and excreted from the body. By contrast, vitamin C is absorbe...

OHSU surgeon implants donated tissue allografts

...es of the Joint Restoration Foundation has already proven valuable. Several OHSU patients have recently benefited directly from the increased availability of fresh tissue for transplantation performed for complex joint cartilage restoration procedures. Patients diagnosed with osteochondral injury, or ca...

Fighting influenza & co. with 40,000 blood samples

...ree years. With other diseases it has already been proven that the older body can no longer produce a sufficient amount of effective antibodies. 'We want to know in particular whether this is the case with infectious diseases where the viruses were discovered recently,' Oliver Schildgen says. SARS's lit...

Rapid, Low-Cost DNA Testing

...anded DNA are (nominally) negatively charged, this proven phenomenon intrigues the research group. The new assay determines whether a fluorescently-tagged short probe sequence of single-stranded DNA matches a sequence in the target analyte. When it does not, the fluorescently tagged probe adsorbs on a go...

Protein overexpression at heart of heart failure

... failure type?of single L-VDCC characteristics was proven when the authors developed a novel, cardiac-specific, drug-inducible beta 2a subunit overexpression transgenic mouse which was crossbred with the channel pore overexpressing mouse when still nonfailing (“Adaptive phase?. In the nonfailing double tran...

FSU researchers determine a critical factor in workings of proteins

HIV protein enlisted to help kill cancer cells

... the tip of the iceberg," he says. "Now that we've proven we can do this, we've started creating a battery of proteins that can push cancer cells to die." Hawkins says he thinks treatments that activate apoptosis mechanisms could provide new options for patients with the deadliest cancers ?such as pancrea...

QUT scientists on the way to sifting out a cure for HIV

... technology into a commercial product. "We have proven the technology works, so the initial research has been done," he said. "We now need a partner to come on board and help us develop this technology into a product that has the potential to save the lives of people with HIV." ...

Scientists unlock mystery of embryonic stem cell signaling pathway

...a layer is needed because it is currently the only proven method to provide the stem cells with the necessary chemical signals that prompt them to stay undifferentiated and to continue dividing over and over. Still, growing human embryonic stem cells on a layer of mouse fibroblasts has never made much se...

Batten down the hatches against HIV

... Liposomes, tiny bubbles of fat, are safe but have proven to be ineffective for use in T-cells. Dai and his co-workers have tested a new transport system: carbon nanotubes are known for their abilities to be absorbed by cells and to smuggle other molecules in at the same time. The researchers attached phosp...

NIH announces phase III clinical trial of creatine for Parkinson's disease

...odopa, can reduce the symptoms of PD, there are no proven treatments that can slow the progressive deterioration in function. Creatine is marketed as a nutritional supplement. Studies have suggested that it can improve the function of mitochondria, which produce energy inside cells. It also may act as ...

Whitefly spreads emerging plant viruses

"As the population levels of the whitefly B. tabaci continue to remain robust, new species of plant viruses will continue to emerge and cause damaging diseases...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

...highlights the urgent need to intensify and expand proven prevention methods, and further, to identify and implement new methods of HIV prevention. A number of observational studies have indicated that HSV-2 enhances the risk of HIV-1 acquisition by around three-fold2. HSV-2 infection may also increase HI...

Organic is healthier: Kiwis prove that green is good

...rchers at the University of California, Davis have proven that organically grown kiwifruit contain more health-promoting factors than those grown under conventional conditions.
