'Virtual Patient' to simulate real-time organ motions for radiation therapy

...otographic Man (VIP-Man). This virtual model is an extension of Xu's ongoing project involving the 3-D VIP-Man, which is an advanced computer model that simulates in 3-D how radiation affects the organs and tissues in the human body. "Live patients are not static beings, and a moving organ such as the lung ...

...vous tissue already coupled to electrodes. Like an extension cord, of sorts, the non-electrode end of the lab-grown nervous tissue could integrate with a patient's nerve, relaying the signals to and from the electrode side, in turn connected to an electronic device. This system may one day be able to ret...

Motor protein plays key role in connecting neurons

... netrin-1, a guidance cue for helping the arm-like extension of the cell, called the axon, grow in the right direction. Cells eventually communicate through synapses at the end of these cellular projections. "During early development, axons need to grow, they need to find a target, they need to decide how l...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...s that activate Sir2, an enzyme linked to lifespan extension in yeast and other lower organisms. For the last 70 years, scientists have been able to increase the lifespan of a variety of species by reducing their normal food consumption by 30 to 40 percent - a diet known as calorie restriction. Through this r...

Growth factor stimulates rapid extension of key motor neurons in brain

...e survival of many types of cells stimulates rapid extension of corticospinal motor neurons ?critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease).

Record ozone loss during 2006 over South Pole

...quare km, nearly as large as the record ozone hole extension during 2000, and the depth of the ozone hole is around 100 Dobson Units, rivalling the record low ozone values in 1998. This year's record ozone loss was reached because these two measurements occurred during the same time period. (A Dobson unit is a...

UGA scientists unravel 'molecular inch-worm' structure of walking-pneumonia bacterium

...e described in new, precise detail the unique cell extension that forms on one end of the bacterium Mycoplasma pneumoniae. This structure, called a "terminal organelle," performs several tasks for this pervasive bacterium and even acts as a "molecular inch-worm," helping the microorganism move. "Mycoplasmas ...

New angiogenesis finding may help fight cancer growth

...and during angiogenesis, they migrate, starting an extension of the blood-vessel network. When Paul added NK-B to endothelial cells, "They lost the capacity to organize in three dimensions, to form the tubes that are the precursors to new blood vessels," Bresnick says. "Then we got excited." Further tests s...

Gut microbes' partnership helps body extract energy from food, store it as fat

The ankyrin repeats showed no sign of wear after multiple stretch-relaxation cycles over a large range of applied forces, the team found. When extended past their breaking points, the molecules exhibited a saw-t...
