Chemotherapy temporarily affects the structures of the human brain

11-27-2006 · EurekAlert!

Researchers have linked chemotherapy with short-term structural changes in cognitive areas of the brain, according to a new study. The study reveals that within 12 months of receiving adjuvant chemotherapy, significant regions of the brain associated with memory, analysis and other cognitive functions were significantly smaller in breast cancer patients who received chemotherapy than those who did not.

  1. DNA is blueprint, contractor and construction worker for new structures
    01-30-2008 · EurekAlert!
    DNA is the blueprint of all life, giving instruction and function to organisms ranging from simple one-celled bacteria to complex human beings. Now Northwestern University researchers have used DNA as the blueprint, contractor and construction worker to build a 3-D structure out of gold, a lifeless material. Using just one kind of nanoparticle the researchers built two very different crystalline structures by changing one thing -- the strands of synthesized DNA attached to the tiny gold spheres.

  3. Structure essential for brain remodeling identified
    12-06-2006 · EurekAlert!
    During learning and memory formation, the brain builds or remodels tiny structures on the surface of its nerve cells to store the new information. Now, a team led by Duke University Medical Center researchers has discovered where the brain gets the raw materials for such construction -- and has even taken "home movies" of the process.

    12-01-2006 · EurekAlert!
    Mayo Clinic researchers have discovered a protein interaction that may explain how the deadly Huntington's disease affects the brain. The findings, published in and featured on the cover of the current issue of Human Molecular Genetics, show how the mutated Huntington's protein interacts with another protein to cause dramatic accumulation of cholesterol in the brain.

  8. Crystal structure enables tailoring of pharmaceuticals against asthma
    07-16-2007 · EurekAlert!
    Researchers at Karolinska Institutet in Sweden have managed to elucidate the crystal structure of a human membrane protein -- LTC4 synthase -- which has a major influence on the development of asthma. LTC4 synthase is extremely difficult to analyze, and previously only low resolution information has been available on two membrane protein structures from human. The scientists now believe that their work will enable the development of new and better therapeutics against inflammations in the pulmonary tract.
