New lead reported in tumor angiogenesis

...ton, sends a signal within these cells to grow and sprout new capillaries. The finding, while technical in nature, has potentially major implications for anti-angiogenic therapy, one of the hottest areas in cancer research. Dr. Cun-Yu Wang, a scientist at the University of Michigan and senior author on the...

A new window into structural plasticity in the adult visual cortex

...rons in the adult neocortex can grow, retract, and sprout new additions--without experimental manipulations. It remains to be seen whether the structural plasticity seen here underlies observed functional reorganizations. Probing this question will depend on determining what kinds of structural changes mig...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

...e Wisconsin study showed an ability to recover and sprout new fibers. "It actually seems to work better in the terminal (striatum)," Svendsen says. "The bonus is it gets transported back to the substantia niagra." The transplanted cells, according to Behrstock, survived and continued to produce GDNF in la...

Scientists discover a genetic switch that links animal growth and cancer

...de a seed. Only when the seed senses water will it sprout and initiate development into a mature tree. Many animals similarly halt their development until the environment is right for growth and development." The process is the same with cells, the basic units of life. Many cells remain in a quiescent stat...

Computer simulation hints at new HIV drug target

...(See illustration.) Frayed whiskers even appear to sprout from the bottom. The similarity to a face ends at the top of the molecule, where two flaps open to reveal a cavity. That is where enzymes and other proteins are cleaved into the parts necessary to assemble infectious virus particles. Structural studi...

Major WHO study concludes calcium supplements can reduce complications during pregnancy

...(See illustration.) Frayed whiskers even appear to sprout from the bottom. The similarity to a face ends at the top of the molecule, where two flaps open to reveal a cavity. That is where enzymes and other proteins are cleaved into the parts necessary to assemble infectious virus particles. Structural studi...

Long-term changes in experience cause neurons to sprout new long-lasting connections

...have discovered that neurons in the brains of mice sprout robust new connections when the animals are adjusting to new experiences. The new connections alter the circuitry of the brain by changing communication between neurons. The researchers said their findings aid understanding of how procedural learnin...

Spinal cord bridge bypasses injury to restore mobility

... out of comas after many years as the nerve fibers sprout through weakened or remodeled areas of the scar. About 16 years ago, Silver also made another find that proteoglycans, a sugary protein, is present at the site of spinal cord lesions. He also knew that a particular enzyme from the bacteria Proteus...

Salk and Stanford teams join forces to reveal two paths of neurodegeneration

...nt foliage, either vegetal or neuronal, must first sprout and then be sculpted into an ordered structure. Neurons extend fibers called axons to target cells in an exuberant manner--some branch to the "wrong" cells while others shoot past their target cells. Axon pieces that went astray degenerate, effectiv...

Tamed 11,400 years ago, figs were likely first domesticated crop

...opagated: A piece of stem stuck in the ground will sprout roots and grow into a plant. No grafting or seeds are necessary. Bar-Yosef, Kislev, and Hartmann suggest that this ease of planting, along with improved taste resulting from minor mutations, may explain why figs were domesticated some five millennia ...

St. Jude finds clues to hearing loss from chemotherapy

...ir cells in the inner part of the ear. These cells sprout extremely fine hairs that move in response to sound waves and set up the electrical impulse that goes into the brain. These are the same cells damaged in adults by prolonged exposure to loud noise. "In the future we'd like to be able to prevent the l...

Conceptualizing a cyborg

...plates of neurons are grown in a bioreactor. Axons sprout out to connect the neuron populations on each plate. The plates are then slowly pulled apart over a series of days, aided by a precise computer-controlled motor system, until they reached a desired length. For the interface, one of the plates i...
