New GI technologies improve internal organ visualization

...d sedation (CAPS), which uses computer software to facilitate precise control of drug delivery. Anesthesiologists and physician/nurse care teams in the study first injected 24 patients (12 colonoscopy and 12 endoscopy) with a single dose of fentanyl as pre-medication, then administered propofol using the CAP...

Neurons grown from embryonic stem cells restore function in paralyzed rats

... rolipram and dbcAMP, growth factors, and cells to facilitate the repair of the injured spinal cord." Previous studies have shown that stem cells can halt spinal motor neuron degeneration and restore function in animals with spinal cord injury or ALS. However, this study is the first to show that transplanted ...

On the track of tiny larvae, a new model elucidates connections in marine ecology

...uding small larvae, in part because such movements facilitate normal biological connections among geographically separate populations. Although tiny larvae are impossible to follow directly, advances in modeling ocean currents have made it possible to predict larval movements. However, until now it has remained...

NASA technology helping injured US troops

...aid Castleberry. "It's very important to NASA to facilitate licensing of our technologies when possible for the benefit of the broader community," said Nona Minnifield Cheeks, chief of Goddard's Office of Technology Transfer in Greenbelt, Md. "Our research and technology can and does often have useful applica...

Viagra improves high altitude exercise performance up to 45% for some

...marked hormonal changes at altitude. These changes facilitate oxygen delivery. However, this benefit is suppressed when individuals don't eat enough and the body shifts focus to store more energy, Friedlander explained. That study appears in the June issue of the American Journal of Physiology-Endocrinology and...

Chimpanzees can transmit cultural behavior to multiple 'generations'

...-based Living Links Center, established in 1997 to facilitate primate studies that shed light on human behavioral evolution, may expand on these findings by examining the cognitive mechanisms involved in cultural learning and the generational transmission of behavior and traditions. For more than seven decad...

Bacteria beat the heat

...an envision using this knowledge, for instance, to facilitate enzymatic reactions in different applications, enhance crop production in areas subject to extreme temperature changes or create new resources for biofuel production that will not only provide more biomass per acre, but absorb more of the greenhouse ...

Speeding discovery of the 'human cancer genome'

...er geneticists and biologists will be essential to facilitate and accelerate the translation of our genomic knowledge into cancer drugs that will impact patient survival," she wrote. ...

Landmark discovery of a Kaposi's sarcoma-associated herpesvirus receptor

...d by KSHV itself. This suggests that the virus may facilitate its own infectivity and dissemination in the body by inducing a physiological state that results in increased numbers of its own receptor. "The advancement of knowledge achieved in this study highlights the outstanding intramural research that takes...

Salmonella bacteria use RNA to assess and adjust magnesium levels

...ist it into different configurations that block or facilitate the production of the protein encoded in the message. Previously identified riboswitches respond to organic compounds such as nucleotides and sugars. The Salmonella riboswitch, reported in the April 7 issue of the journal Cell, responds to magnesiu...

FDA approves first medical device using rutgers biomaterial

...rgical mesh improved handling characteristics that facilitate precise placement during the surgical repair and leave less implant material following the resorption of the coating. Hernias occur when musculature fails and one part of the body protrudes through the resulting gap or opening into another part of ...

Invasive exotic plants helped by natural enemies

...rcent over native plants. "Exotic herbivores may facilitate the growth of exotic plants by selectively consuming native plants, potentially freeing resources for exotic plants that can resist these herbivores," said John Parker, graduate researcher in the School of Biology at the Georgia Institute of Technolo...

Penguins waddle but they don't fall down, UH researchers say

...we're hopeful about the results," Kurz said. To facilitate his study, Kurz has created a special platform that contains a pressure mat. As penguins walk across the mat, it measures the variability in the width and length of their steps. The data will provide insight into the natural mechanics and stability...

Anti-HIV drug has potential to prevent transmission in women

...ions and inflammation in women that could actually facilitate HIV transmission. The favorable findings of the tenofovir gel's Phase I safety and acceptability trial has already led to a larger Phase II safety study in at-risk women due to begin in the spring of 2006. According to the study, there was a high a...

Rare Chinese frogs communicate by means of ultrasonic sound

...ghai. "Nature has a way of evolving mechanisms to facilitate communication in very adverse situations," Feng said. "One of the ways is to shift the frequencies beyond the spectrum of the background noise. Mammals such as bats, whales and dolphins do this, and use ultrasound for their sonar system and communica...
