Study in Science holds promise for a new approach to drug therapy

... cells home in on the site of infection. The other involves pain relief brought about by morphine. In white blood cells, the free G protein gamma-beta subunit activates enzymes that allow the cells to home in on the site of infection. Researchers found that pre-treatment of white blood cells with M119 reduc...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...ose who experience a first heart attack. The study involves an intravenous infusion of adult mesenchymal stem cells from healthy donor bone marrow that might possibly reverse damage to heart tissue. A unique benefit of the stem cell product is that it is given to patients through a standard IV line. Other t...

Virginia Tech helping to develop higher quality, disease-resistant wheat varieties

...ect is called Marker Assisted Selection (MAS). MAS involves the direct use of molecular markers that are located in the same chromosome region as the trait of interest to select for genes controlling useful agronomic traits. Breeders use these molecular markers to increase the precision in selection of variet...

Study suggests that publicly available genome data may contain small but significant errors

...scribe a high throughput microarray technique that involves testing many samples simultaneously and which can be used to assemble physical maps and validate genomic sequence assemblies. The findings appear in the latest issue of the Journal of Computational Biology. The research was conducted by Joseph W...

Defective immune system response to smallpox vaccine detailed in new study

...o eczema vaccinatum, notes Dr. Leung. One approach involves developing drugs to mimic the action of LL-37 or developing LL-37-containing creams that could be applied to the skin in order to boost its ability to contain vaccinia virus infection. Another approach could be to develop agents to neutralize IL-4 an...

Attention shoppers: Researchers find neurons that encode the value of different goods

...." In general, it is believed that economic choice involves assigning values to available options. However, the underlying brain mechanisms are not well understood. In the study, Padoa-Schioppa and John Assad, PhD, HMS associate professor of neurobiology, found a population of neurons located in the orbitof...

Researchers release new variety of asparagus

...r campus. The first test of the new variety, which involves evaluation of yield, spear quality, and other traits, was started in 1990. A full harvest of DePaoli was obtained three years after planting. To ensure that the new variety was not susceptible to disease, it was then harvested for a few additional y...

Genome sequencing is for ecologists, too

...ility in Walnut Creek, Calif. Shotgun sequencing involves breaking a whole genome into smaller, more digestible DNA segments, then sequencing each one. The Daphnia genome was sequenced over eight times to ensure better coverage of all 12 pairs of chromosomes. Daphnia's short generation time and small genom...

CU, USDA team to curb two invasive, poisonous vines

.... "The collaboration between Cornell and the USDA involves studies of the plants' biology to identify weak links in the life cycle that should be targeted, if possible, for biological control," said Lindsey Milbrath, a USDA-ARS research entomologist at Cornell, adding that introducing any agent will require ...

'Executive' monkeys influenced by other executives, not subordinates

...llowing is more than a reflex action; that it also involves lightning-fast social perception. Such a discovery in monkeys gives the researchers an invaluable animal model that enables them to tease apart the reflexive-versus-social mechanisms that govern behavior, they said. In particular, they can begin to...

Rice bioengineers pioneer techniques for knee repair

...ngineering. Athanasiou's new self-assembly method involves a break from conventional wisdom in bioengineering...liminate rejection risks. Most tissue engineering involves honeycombed plastic templates or hydrogels called scaffolds that are used to guide colonies of donor...

MIT chemist discovers secret behind nature's medicines

...ure accomplishes it almost nonchalantly. The trick involves using a turbo-charged enzyme containing iron. A clue to how these enzymes operate emerged from a 2005 study by Christopher T. Walsh of Harvard Medical School, Drennan's collaborator and co-author of the study published in the March 16 issue of Natur...

Picking apart how neurons learn

...ur. The second critical step in establishing LTD involves a chemical change to the AMPA receptor, called phosphorylation. Mice lacking a small part of the AMPA receptor - the part where phosphorylation is thought to occur - do not undergo LTD. This result confirms that phosphorylation is an essential step t...

Technique makes it easier to see mouse embryo in all its glory

...ster '" and more accurate. Traditional histology involves embedding embryos in wax, thinly slicing the wax and delicately placing it on slides, staining the sections and viewing slides under the microscope, then mentally reconstructing the three-dimensional aspects of the embryo to reveal pertinent biologic...

Bones from blood: Scientists aim to break new ground on fractures

...ures. The three-year ?.5 million research project involves scientists in the UK and across Europe, as well as academics from the University of York's Departments of Sociology and Philosophy, who will carry out sociological and ethical evaluations of the work. The project will seek to find a viable new medica...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...or David Huddart from John Moores University, also involves scientists from Bournemouth University, the University of Oxford and the Australian National University. They have yet to publish a peer-reviewed analysis of the footprints. In all, the British team claims to have found 250 footprints - mostly human...

Scientists directly view immune cells interacting to avert autoimmunity

...ool, Tang said. "The function of the immune system involves multiple cell types interacting dynamically in three dimensions, which is very difficult to analyze in vivo -- and nearly impossible to authentically reproduce in vitro." The team of immunologists and diabetes researchers used the new microscope to ...

New nanosensor uses quantum dots to detect DNA

...for genetic defects and mutations." The technique involves an unusual blend of organic and inorganic components. "We are the first to demonstrate the use of quantum dots as a DNA sensor," Wang said. Quantum dots are crystals of semiconductor material, whose sizes are only in the range of a few nanometers a...

Scientists crack code for motor neuron wiring

...isease. The studies suggest that the code -- which involves members of the family of transcription factors encoded by the Hox genes -- could also govern the establishment of other spinal cord circuits. This circuitry includes interneurons that control motor neuron firing patterns and sensory neurons that tran...

Anyway you slice it, tomatoes cut through drought with new gene

...ould ultimately be applied to all crops because it involves the over-expression of a gene found in all plants," said Dr.Roberto Gaxiola, a plant biologist at the University of Connecticut and the lead author of the study. "It has the potential to revolutionize agriculture and improve food production worldwide...
