A first: Simultaneous PET/MR images of the brain debut, increase molecular imaging capabilities

... image qualities comparable to stand-alone systems without any significant distortions," he said. Pichler explained some of the future possibilities with this PET/MR system. PET currently can differentiate mild cognitive impairment from early-stage Alzheimer's, but it cannot determine reduced brain volume ...

Using positron emission tomography (PET) imagingwith the radiotracer FLT (fluorothymidine)UCLA researchers were able to determine within one or two weeks after starting the treatment whether pa...

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

...ated to GDNF. Control mice received only the virus without the GDNF or neurterin genes inserted. Four weeks after the treatment, rats administered HSV-GDNF exhibited significant recovery of intracavernous pressure (ICP) and systemic arterial pressure (AP) compared with rats treated with the control virus ...

Even without video evidence, scientists have confirmed over the past 10 years that higher organisms use paxillin as a transmitter of locomotion and gene-expression signals from several classes of growth-factor receptors to the nucleus. Cancer researchers are ea...

NSW Department of Primary Industries (DPI) scientists have found very high levels of phosphorus and low levels of organic carbon in vegetable growing soils, during a major research project designed to help Syd...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

Gene therapy offers new hope for treatment of peripheral neuropathy

After the delivery of the therapeutic gene or empty vector (for the control group), the researchers injected the same paws of each rat with formalin, an irritant known to simulate the symptoms of a peripheral neuropathic pain at th...

When the villain becomes your friend: The strange tale of muscle lactate

...ation chemists realized that juice left to ferment without adequate oxygen resulted in acid products. Then, in the early 20th century, when physiologists stimulated isolated frog muscles to contract until exhaustion, they found that the tissues had accumulated high amounts of lactic acid. Since then, the ide...

That lopsided cell division produced one "daughter" like its parent, exhibiting a stem cell-like capacity for self renewal, and another Myf-5 positive cell. The rese...

The main question for conservationists is which of the existing 18 populations of polar bears occurring on two continents and one sub-continent stand the best chance of surviving as the po...

In addition to producing the first chemically operated neuro-memory chip, the researchers propose that their work implies that chemical stimulation may be crucial to learning and memory formation i...
