Promiscuous Catalytic Activity Possessed by Novel Enzyme Structure

...it exactly which reactions to carry out. “The big advantage that we have with our system is that it’s a small, soluble, easy-to-work-with bacterial protein that seems to be able to do reactions that you can find somewhere else in nature, but where people have not been able yet to isolate the proteins,?said St...

Missing Receptor Molecule Causes Tumor Growth

...ontrolled death of single cells, if this is to the advantage of the whole organism. If this process of self-protection does not work then the destructive cells can proliferate uncontrollably. Signal Without Effect Prof. Michael Krainer and his team from the Medical University of Vienna have now been able to p...

Nanoparticles carry cancer-killing drugs into tumor cells

Researchers devise new technique for creating human stem cells

...c cell is by nuclear transfer into oocytes. Taking advantage of this current capability -- such as colleagues in South Korea and other countries are doing -- is critical if we are to maintain the progress necessary to realize the extraordinary clinical potential of this technology." Eggan added that the most ...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...irus at the early stages of an infection. Another advantage of the quantum dots when compared to detection systems that rely on fluorescent protein is that the protein "bleaches out" in minutes while quantum dots maintain their brightness for hours. The image on the right shows a culture labeled with green fl...

Unweaving amyloid fibers to solve prion puzzles

... the more we can get them to self-assemble," a key advantage for nanoscale devices that are very difficult to m...h also makes them attractive for nano devices. The advantage of the yeast protein is that it is not toxic, even for yeast. ...

Modification of program enables prediction of gene transcription

...wn to exist before," Brent said. The system takes advantage of the scarcity of the CG sequence, finding so-called CpG "islands" known to be more common near the transcription-start site. It also has a knack for recognizing sequences that indicate splice sites. Over the past two years, TWINSCAN has been findin...

Genetically engineered animals help in scientific research that may benefit children

...ouis Bugnard inFrance. "This animal model has the advantage of mimicking in a short time the different stages of chronic kidney disease. The combination of genetically engineered animals and this animal model has helped us to decide which molecules to study, or which might be interesting targets for drug deve...

UCSD discovery may provide novel method to generate medically useful proteins

...used by animals to produce antibodies, and has the advantage of giving the protein greater stability." "If we can learn from these organisms how to set up a system that churns out proteins with enormous variability, it may be possible to target these new proteins to specific cells to treat disease," said Ste...

Computers close in on protein structure prediction

...tail in the second stage. The first stage takes advantage of the fact that all amino acids have identical sections, which form the protein backbone. The computer adds a fuzzy picture of the protruding side chains that give each amino acid its unique identity. The sequence of side chains ultimately gives eac...

Stressed cells spark DNA repair missteps and speed evolution

...n physical space at a certain time gives the cells advantage because it reduces the risk to the whole colony. DNA breaks occur only rarely in each individual cell. If the mutations are restricted in time and space, it reduces the risk that the mistakes in repair will affect some other gene. It can also enhanc...

Surgical Robot 'Scrubs In' At UNC, May Be More Precise Than Conventional Surgery

...ision and the ability to zoom in and out. Another advantage with da Vinci is the elimination of tremor. Surgeons can scale, or ratio, their finger movement to that of the robotic instrument. A movement of inches at the console can be scaled down to centimeters in the patient. "This can re-introduce precision...

Elusive salamanders have role in developing new sampling models

...-year SERDP project, which began in January, takes advantage of some of the Department of Energy laboratory's extensive capabilities. In addition to Bevelhimer's contributions in the area of quantitative ecology, other ORNL researchers involved in the project are Neil Giffen, a wildlife biologist, and Bill Har...

Tiny avalanche photodiodes target bioterrorism agents

...l. Solar-blind APDs are intrinsically able to take advantage of this low background level, while PMTs must use external filters to become solar-blind. This makes secure battlefield communication possible utilizing a combination of compact, inexpensive UV LEDs and UV APDs both developed at the Center for Quantu...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

...ultimately, cell division. "Perhaps it's to their advantage that the amnion epithelial cells lack telomerase expression, because telomerase is associated with many cancers and one of the main concerns about stem cell therapies is that transplanted stem cells would replicate in the recipient to form tumors," n...

Virginia Tech football player uses prototype cast

...e Virginia Tech vs. Boston College game. An added advantage to getting the design completed so quickly is that the biomaterials class is linked to the campus of the Wake Forest University School of Medicine. Virginia Tech spearheaded a partnership with this medical school in 2001, and formed the School of Bio...
