Magnetic system could be key to surgery without scars

... to avoid getting their lips pierced. “Once you think about, it’s an obvious thing,?said Dr. Cadeddu, whose team of urologists and surgeons worked with engineers from UTA’s Automation and Robotics Research Institute and the Texas Manufacturing Assistance Center to build the prototype. The system use...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

...s described in the paper", he adds. The authors think their study could be a useful reference for other centres where cephalosporin use is higher than in the Royal Free. Compared with many other hospitals, cephalosporin use was already low at the beginning of the study and the intervention was still hig...

Brown team finds crucial protein role in deadly prion spread

...and how fragmentation speeds the spread of prions, think of a dandelion," Serio said. "A dandelion head is a cluster of flowers that each carries a seed. When the flower dries up and the wind blows, the seeds disperse. Prion protein works the same way. Hsp104 acts like the wind, blowing apart the flower an...

Nanoparticles can track cells deep within living organisms

...bons in labeled stem cells to actually see them. I think we've dispelled that notion, and the fluorine imaging approach already is becoming more popular for molecular imaging of various cell and tissue types." Next the research group will evaluate how nanoparticle-labeled cells function in living organi...

Anti-dandruff compound may help fight epilepsy

...nel protein and allow more potassium flow. “If you think of these channels as doors on the cell’s surface,?Li says, “then ZnPy made this door both easier to open and stay open longer. It’s like a tunable hinge that helps sticky doors swing freely.? The researchers then tested defective channels that con...

Swimming 'to the left' gets bacteria upstream, and may promote infection

...ood and better conditions for multiplying. "We think that upstream swimming of bacteria may be relevant to the transport of E. coli in the urinary tract," said Köser. "It might also explain the high rates of infection in catheterized patients and the incidence of microbial contamination at protected we...

Smokers quit after damage to brain region

...est on this platform. "It's really intriguing to think that disrupting this region breaks the pleasure feelings associated with smoking," said Damasio, director of the institute and holder of the David Dornsife Chair in Neuroscience at USC. "It is immediate. It's not that they smoke less. They don't sm...

Syphilis rate on rise in US gay, bisexual men

...,000. Among other factors, public health officials think the rates dropped because fewer people were selling sex to get crack cocaine as the decade went by. However, the syphilis rate rose by 19 percent between 2000 and 2003. During that period, the rates among women continued to slide ?by 53 percent...

Scientists reveal structure of gateways to gene control

MIT's ocean model precisely mimics microbes' life cycles

Indeed the guiding principle of the new mod...

UCLA: How does your brain respond when you think about gambling or taking risks?

Genes and genius: Researchers confirm association between gene and intelligence

"I think all of the genes involved probably have small, cumulative effects on increasing or decreasing I.Q., and I expect overall intelligence is a function of the accumulation of all of these genetic variants, not to mention environmental influences ranging ...

Breathing easy: When it comes to oxygen, a bug's life is full of it

... amounts of oxygen, and so it might be tempting to think they are panting ?tiny inaudible pants. They are not, because they do not breathe through noses or mouths. Instead, insects draw in oxygen through holes in their bodies known as spiracles and pump the oxygen through a system of increasingly tiny tube...

Faster, low cost sequencing technologies needed to drive era of personalized medicine

...uence an individual genome for $1,000, you have to think about using nanotechnology," said Zhang, associate research professor in the Center for Single Molecule Biophysics at the Biodesign Institute. "The technology is available now to pioneer a new approach to sequencing." Much like the computer indu...

Researchers show that veins stiffen as we age

...onse of the veins in either age group. "Thus, we think that the stiffening of our veins as we age is probably due to structural changes, such as a thickening of the vein walls," Farquhar said. "Hardening of the arteries is a good analogy for what is happening in our veins as we grow older." So can we d...

The researchers note that despite the national Back to Sleep campaign, which urges caregivers to put bab...
