U of M researchers discover genetic key to treating deadly fungal infections

...n isochromosomes, which means that the finding may yield clues about how some tumors become resistant to chemotherapy and how researchers can develop companion drugs that inhibit the development of that resistance. About 25,000 Americans develop these fungal infections each year. And in spite of treatm...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

...a blood vessel. The idea is if we can optimize our yield we can more easily obtain the large number of specific cells required to make a blood vessel." ...

Food-crop yields in future greenhouse-gas conditions lower than expected

...ndicate a much smaller CO2 fertilization effect on yield than currently assumed for C3 crops, such as rice, wheat and soybeans, and possibly little or no stimulation for C4 crops that include maize and sorghum," said Stephen P. Long, a U. of I. plant biologist and crop scientist. FACE technology, such as ...

Radiation-killed bacteria vaccine induces broad immune response in mice

...adiation-inactivated whole pathogens could rapidly yield vaccines against such bacterial diseases as typhoid, cholera, tuberculosis and other diseases of public health concern, such as intestinal parasites. This strategy might also be deployed in the event of epidemic outbreaks or against bioterrorist atta...

New MRI technique quickly builds 3-D images of knees

...ns acquire images as a series of 2-D slices, which yield high resolution in a single plane and poor resolution in the remaining direction, he says. To capture an image, a magnetic resonance scanner commonly conducts hundreds to thousands of little "experiments," or encodings, that help to make up the big...

Scientists uncover rules for gene amplification

...ene and the telomere, then the amplification would yield a homogenously-staining region." adds Vidhya Narayanan a Ph.D. student in Kirill Lobachev's lab and first author of the study. The findings can help researchers understand the cause of cancer in diseased individuals and also to potentially identify ...

Researchers identify genes in fruitflies that may shed light on human cancer spread

...s, for example ?have been successful but generally yield information about genes with unique functions only, and only one gene at a time. Whole genome studies, like the microarray analysis used in this study, allow researchers to identify genes that share similar functions in a way that mutational analysis...

Pesticides in the nation's streams and ground water

...here, when, and why specific pesticides occur, and yield science-based implications for assessing and managing pesticides in our water resources." The USGS findings show strong relations between the occurrence of pesticides and their use, and point out that some of the frequently detected pesticides, in...

Taipan venom no snake oil

...ll the venom components from Australian snakes may yield further novel components thatcould be targeted as human drugs. ...

Gene thwarts some pathogens, gives access to others, could save crops

...he answers eventually could lead to increased crop yield and decreased produce loss due to Botrytis and other similar pathogens, he said. Currently, the gray mold disease caused by Botrytis destroys about 10 percent of the grape crop annually and about 25 percent to 30 percent of tomato and strawberry cro...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

...anned exploration of the New England Seamounts may yield new species, but most certainly will provide first records of plants or animals found in other parts of the world, such as the Mid-Atlantic Ridge or the eastern North Atlantic. We associate corals with warm tropical waters rather than the cold Gul...

How sperm crack the whip

...payload to the egg, he said. Such research could yield insight into some male infertility, said Clapham. Still-unidentified mutations in any of the four CatSper proteins ?all of which are involved in motility ?could underlie some forms of infertility, he said. "Also, these proteins are good targets for...

Research details how a virus hijacks cell signals to cause infection

...iously unknown. "Eventually this understanding may yield clinical benefits, by contributing to future therapies to block viral infections. For now, we have learned more about cell functions, and how viruses may evolve unexpected methods to force themselves into cells." ...

HortResearch science reveals the natural potential of apples

... "Further work with the database will undoubtedly yield even more exciting advances in the future." Releasing the ESTs into the public domain will serve to enhance the speed of discovery. "We will see a multiplier effect, where discoveries made in other countries will benefit our work and speed up culti...

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

...sarium head blight result in significant losses in yield and quality each year. For example, researchers will be identifying and using DNA markers to select varieties possessing genes conferring durable resistant to powdery mildew, which causes annual crop loss of 10 to 30 percent in the Mid-Atlantic regi...

First SCID gene chip to be introduced at Academy meeting on immunodeficiencies

...archers are optimistic that stem cell research may yield new treatments in the future. The conference coincides with the 20 year anniversary of the Jeffrey Modell Foundation, a not-for-profit organization dedicated to PI research, physician education and patient support. Among the highlights of the co...

The evolution of food plants: Genetic control of grass flower architecture

...the potential to lead to increased seed number and yield in some cereal grasses. This might not be true for maize because of the structure of the ear, but one can imagine that a ra2 mutant of barley, rice or sorghum might have more branches, and thus produce more seed". ...

Researchers release new variety of asparagus

...ed a new variety of asparagus that offers a higher yield than previous varieties of the vegetable and boast...by a high percentage of marketable spears. Higher yield of marketable spears reduces the impact of high land and labor costs, thereby making the asparagus m...

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice
