Production of key Alzheimer's protein monitored for first time in humans

...e but only through recent technical and procedural advances has become sufficiently sensitive. Via an intravenous drip, scientists give test subjects a form of the amino acid leucine that has been very slightly altered to label it. Inside the leucine are carbon atoms with 13 neutrons and protons in their nucl...

New MRI technique quickly builds 3-D images of knees

... capitalizes on recent magnetic resonance hardware advances that, coupled with a novel way of maintaining a high-level magnetic resonance signal throughout the scan, will speed an MRI session. "But to maintain the high-level signal," he says," you need to be able to complete each of these smaller encodings wi...

Epidemic of unneeded amputations

...uickly to amputation rather than exploring medical advances that can prevent limb loss," said Dr. Craig Walker, of the Cardiovascular Institute of the South, in Houma, La. Walker is a pioneer in a medical procedure to combat these trends: Cool Laser Revascularization for Peripheral Artery Therapy, or "CLiRpa...

UC San Diego biologists solve plant growth hormone enigma

...doctoral fellow working with Zhao. "Even with the advances in technology, it took about three years to produce plants lacking at least four of the 11 YUCCA genes." Disrupting one YUCCA gene did not have any obvious effects. Therefore, there is overlap in the functions of the genes in this family. Howe...

Discovery may speed forest biotechnology

...op plants, and this may open the door to important advances in intensive forestry and fruit tree improvement. Information of this type, researchers say, may also help scientists better predict how some types of trees and tree populations will respond to climate change. "Before this we never really knew what...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

... videos were made possible by recent technological advances together with techniques the von Andrian lab developed. *Henry Pickering Bowditch Award Lecture: "Migrants on a single-minded mission: How T cells find their antigen," 5:45 p.m., Sunday, April 2, Room 134, Convention Center Room 134. Speaker: Ulrich...

Prenatal nicotine exposure reduces breathing response of newborns...

...rn prematurely. While doctors have made tremendous advances in caring for babies born too soon and too small, scientists have not yet developed effective ways to help prevent premature delivery. Finding why mothers give birth prematurely is important for the health of the baby and mother and to drive down me...

First link of oral bacteria and preterm birth found in human

Pesticides in the nation's streams and ground water

... it may take years for researchers to attain major advances in understanding the actual potential for effects. Our results indicate, however, that studies of mixtures should be a high priority." ...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

...iorefinery, which is designed to take advantage of advances in plant science and innovative biomass conversion processes and equipment to produce fuels, power and chemicals from biomass. The biorefinery would work much like a petroleum refinery, which produces multiple fuels and products from petroleum. The...

Genetically engineered mosquitoes show resistance to dengue fever virus

...and biochemistry, has made a number of significant advances on genetic approaches to interrupt malaria parasite and dengue virus transmission by mosquitoes. He has received a number of international awards for his research. In 2005, he received a $19.7 million grant from the Foundation for the National Inst...

Novel method reveals how menthol discovery could point towards new or improved pain therapies

This new understanding could lead to potential advances in pain therapy, the researchers said. Moreover, the scientists envision that their method may be potentially useful in studying the activation mechanism of other drugs and proteins. "Because our ability to sense temperature is closely linked to ou...

A new way of looking at molecular motors

...sts, parasitologists, and medical researchers make advances in a wide variety of fields, from veterinary medicine to tropical diseases. ...

Two NIH initiatives launch intensive efforts to find roots of common diseases

UCSD team unmasks family of immune system invaders

...ty of Toronto," said Dixon. "This illustrates how advances in a field like bacterial pathogenesis requires the talents and diverse expertise of many scientists." Their insights into the mechanisms of bacterial pathogens could lead to novel treatments for diseases such as dysentery. These findings may prove...

Genomics-based vaccine could prevent deadly cattle disease

...derstand and fight T. parva , scientists may make advances against related parasites that cause malaria, tuberculosis, and other diseases in which killer T cells also play a role in immunity. What's more, because T. parva launches a cancer-like illness inside the white blood cells of cattle, it may provide ...

Absence of critical protein linked to infertility

...iod, an embryo attaches to the wall of the uterus, advances into it and eventually attaches to the blood supply and forms the placenta. For a successful pregnancy to occur, stromal cells of the uterus must be transformed into decidual cells, which secrete nutrients that allow the embryo to survive until it pl...

Earth Rx: A microbial biotechnology prescription for global environmental health

...n of the organic material in sewage. With recent advances in biology, materials, computing, and engineering, environmental biotechnologists now are able to use microbial communities for a wealth of services to society. These include detoxifying contaminated water, wastewater, sludge, sediment, or soil; cap...
