Non-Surgical Treatment Ends Pelvic Pain In Women
...ect pelvic congestion syndrome, radiologists first insert
acatheter into a vein in the neck, groin or arm and guide it to the pelvis. Afluid is injected to make the veins in the pelvis visible on X-ray. If the X-rayshows very tightly coiled veins, tiny coils or glue-like liquids are introducedthrough the ca...
MIT's Mini Respirator Breathes Life Into Mutant Mice
...cause the animals are toosmall. "Even if you could insert
a tube into the trachea, any bit of moisturewould clog up the airways," Dr. Poon said. The MIT machine, which is patent pending, incorporates several novelfeatures. For example, the double pistons that drive the pressure fluctuationsin the c...
Researchers Take Major Step Toward Cracking Ebola Code
...ected by using a technique of moleculargenetics to insert
this protein on the surface of another virus---a mouseretrovirus---which carried a reporter gene (a gene that encodes a protein whoseactivity can be readily measured in the laboratory) to identify infected cells. Researchers had hypothesized that the...
Duke Researchers Develop First Treatment For Rare Muscle Disease
...e researchers used molecular biology techniques to insert
the humangene for GAA into a common type of cell grown in the laboratory. These cells actlike a mini-factory, churning out human GAA enzyme. After several years ofexperimentation, Chen and his colleagues obtained enough purified enzyme tobegin tests ...
'Rolling Circles' Provide New Way to Amplify and Detect DNA
...DNA. The sameis true of cloning, where scientists insert
a piece of DNA intoa bacterium so the organism's own replication machinery will copy it. The third widely used option for making short strands ofDNA, computerized chemical synthesis, relies on a machine tosynthesize DNA sequences from free DN...
Study: Hydrogen Bonds Aren't Key To DNA Pairing After All
...d the tables and studiedwhether a polymerase would insert
the mimic itself opposite anadenine template. Not only was the mimic inserted opposite adenine, it was chosen as adenine's partner with nearly the same frequency as thymine itself. "Scientists already know that fluorocarbons such as difluorotolu...

itself into the cell membrane," according to Zeneca's De Souza, who has spent three years at Duke University investigating this gene. "Instead of carrying out its normal regulatory functions, this shortened protein leaves the cell. Once outside, it...
