Brain May Be Less Plastic Than Hoped

.../p> The study also establishes fMRI as a valid method to measure reorganization in the monkey brain, Smirnakis added. Similar studies could one day show scientists how to help the brain to recover from injuries. “In humans, studying brain reorganization is difficult. Cortical injuries are not happening ...

Stealth Worms May Improve Insect Pest Control

...cts quickly. Depending on climate conditions, this method works best on greenhouse ornamentals and vegetables, citrus, cranberry, turfgrass and other crops, rather than on high-acreage crops like cotton and soybeans. "The beauty of this is that in the last 20 years nematodes have been formulated and commer...

Wake Forest scientists find new combination vaccine effective against plague

...otein taken from plague bacteria into a mouse ?one method of vaccination ?produces little if any response in the mouse immune system. But if a protein termed flagellin is added to the vaccine, antibody levels against the plague bacteria are 500,000 times higher. "Flagellin can function as an effective adju...

Newly Discovered 'Branding' Process Helps Immune System Cells Pick Their Fights

Scientists have uncovered a new method the immune system uses to label foreign invaders as targets to be attacked. Researchers showed that the immune system can brand foreign proteins by chemically modifying their structure, and that these modifications increased the chances that cells kn...

Microarrays as phenotype

Microarrays provide a method of quantifying the expression and order of genes in a particular genome -- acting as a surrogate measure of cell physiology, said researchers at Baylor College of Medicine in a report that appears online today in the journal Nature Genetics. "Microa...

Building a protein name dictionary from full text: a machine learning term extraction approach

...e commonly found in full text material. We use the method to create a protein name dictionary from a set of ...full text. Conclusions This dictionary term lookup method compares favorably to other published methods, supporting the significance of our direct extraction ...

Remote control flies? Fly behavior controlled by laser light

...s write. Miesenböck also says "one could use this method to restore neural signals that have been lost" due to injury or disease, such as in spinal cord trauma, although he notes that the possibility is "far-fetched" at the moment. The remote control is based on the idea that specific nerve cells could be...

Owl genomics presents a HEPATOCHIP for diagnosis of non-alcoholic steatohepatitis

...egorio Marañón Hospital (Madrid). This HEPATOCHIP method determines the co-expression of genes in the liver tissue sample, providing monitoring treatment regimens to check progression/regression of these liver pathologies. This HEPATOCHIP can be used as a prognostic tool for NASH-predisposed patients, to ...

Purdue researchers use enzyme to clip 'DNA wires'

...aining specific sequences of genetic material, the method might be used in the future to cut DNA wires of varying lengths for building electronic devices. Ivanisevic and former Purdue physics graduate student Dorjderem Nyamjav were the first to coat DNA with magnetic particles two years ago. Kinsella and I...

Researchers pioneer new gene therapy technique using natural repair process

...Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes. The findings are available online in Nature. By artificially initiating a DNA repair process known as homologous recombination, Dr. Matthew Porteus of U...

Sponges as drugs

...in the sea remains the most reliable and effective method for obtaining the large quantities of sponge biomass, necessary for developing drugs. However, sea rearing can only be used for the large-scale production of useful substances if it can yield large quantities of the sponge species. Therefore, sea re...

Whole genome promoter mapping - Human Genome Project v2.0?

... and NimbleGen Systems have developed an efficient method to identify thousands of regulatory sequences in the human genome, according to a study published today in Nature. Genes are defined by their ability to generate a functional product. Thus the 'promoter' - a DNA sequence that controls when and where...

DNA constraints control structure of attached macromolecules

A new method for manipulating macromolecules has been developed by researchers at the University of Illinois at Urbana-Champaign. The technique uses double-stranded DNA to direct the behavior of other molecules. In previous DNA nanotechnology efforts, duplex DNA...
