Detection of DNA on nanotubes offers new sensing, sequencing technologies

...he technique a significant step further. "We have successfully demonstrated the optical detection of selective DNA hybridization on the surface of a nanotube," said Strano, who is also a researcher at the Beckman Institute for Advanced Science and Technology and at the university's Micro and Nanotechnology Labor...

Chemotherapy gel may fight breast cancer and reduce breast deformity

...mmary gland. The researchers found that they could successfully control the delivery of chemotherapy over a period of 30 days and that the tumors were completely eradicated compared to a control group of mice that were implanted with the gel insert without chemotherapy. "Through further research and testing, our...

Cell therapy slows progression of an inherited neurological disease; Improves motor skills in mice

...in-producing cells survived in the mice brains and successfully moved to regions of the brain where they could aid in producing myelin. The transplanted cells also helped lead to production of healthy myelin and improved motor coordination. "There is much excitement in the field of cell-based therapy and this st...

A surprising pair of proteins help make healthy eggs

...Without granulosa cells, eggs cannot mature and be successfully fertilized. How do these handmaidens grow? Biologists at Brown University and the University of California–Berkeley have discovered that two proteins ?TAF4b and c-Jun ?team up to turn on about two dozen genes inside the nuclei of granulosa cells. Th...

Clues to breast cancer hidden inside stem cells

... this compartment. In 2002, Thorarinn Gudjonsson, successfully isolated cells from the human breast with stem cell properties. Gudjonsson immortalised these cells and grew them in three dimensional matrix that mimics the real, living tissue. Biologists have long relied on 2-dimensional cell cultures as the basi...

Successful cell engineering may lead to mad cow prevention, say researchers

Researchers at Texas A&M University have successfully "knocked down" the expression of possible disease-...Medical Institute's Cold Spring Harbor Laboratory, successfully utilized genetic engineering to produce a goat cell line in which the gene encoding for prion protei...

Unique equine cataract surgery offered on routine basis

...t human cataract surgical techniques can translate successfully to bear on an equine problem. We are pleased that ...cale than currently available." The surgery has successfully been carried out on several horses at the University, including TC, a nine-year old Gelding warmbloo...

Testes to incubate stem cells

...ozen for future use. A team in the Netherlands has successfully harvested spermatogonial stem cells from cows and cultured them inside mouse testes. The hope is that the same thing could be done for men. "This is a very promising route to help young cancer patients undergoing chemotherapy," Dirk de Rooij of Utrec...

Anthrax inhibitor counteracts toxin, may lead to new therapeutics

...ve designed a nanoscale assembly of molecules that successfully counteracts and inhibits anthrax toxin in animal a...emonstrating that this approach also could be used successfully to enhance the potency of polyvalent inhibitors directed to this target and, they suggest, others. T...

Defective immune system response to smallpox vaccine detailed in new study

...d LL-37. With the LL-37 supplement, the skin cells successfully controlled the viral replication. Dr. Leung and his group then looked more closely at why vaccinia infection fails to induce LL-37 production in atopic dermatitis skin. Comparing immune responses of skin cells grown in the lab from healthy volunteer...

International HIV/AIDS trial finds continuous antiretroviral therapy superior to episodic therapy

...tries. It began enrollment in January 2002 and had successfully recruited more than 90 percent of its target of 6,000 participants: as of January 11, 2006, when enrollment was stopped, 5,472 volunteers had joined the study. At the time of the DSMB review, the average follow-up was approximately 15 months. The an...

Researchers develop portable 'vein finder' for faster, more accurate injections

...nate the scattering effects." Once the system is successfully adapted for humans, data processing and electronics will be miniaturized in a prototype for field-testing. The researchers envision the final product will be about the size of a fat fountain pen. Compared to existing devices on the market that try ...

NJIT engineer poised to take stem cell research a step forward

...oving that stem cells taken from one person can be successfully implanted into another. A list of conditions for which stem-cell treatment holds promise grows almost daily: It now includes Parkinson's, diabetes, Alzheimer's, cancer and traumatic brain injury. "Treena's research is exciting because she has had s...

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

...it is very expensive to construct a robot that can successfully adjust to side to side, or medial-lateral, motion. Robots currently in use, such as the Asimo robot that mimics human walking patterns, have large, expensive and cumbersome computers built onto their "bodies" to keep them from tipping over when they...

St. Jude projects 90 percent cure rate for ALL

... incorporate the breakthroughs of past decades and successfully overcome the remaining challenges." The dramatic increase in cure rates for children is especially significant in the case of African-American children, Pui noted. They still have poor outcomes in national studies, but studies at St. Jude have show...

Potential heart benefit found in stem cells

...s study, approximately half of the stem cells were successfully transformed into cardiomyocytes (premature cardiac functioning cells) in vitro. "We believe that by looking at these new sources for stem cells, we will eventually be able to use our own stem cells to repair our own heart dysfunctions," said Sunic...

Research could lead to better drugs and whiter whites

...s research could also help us exploit enzymes more successfully and lead to better manufacturing processes in a number of commercial sectors. "In cleaning products, for instance, enzymes help speed up the chemical reactions that break down protein and starch stains; a better understanding of how this process wor...

Plant-derived vaccines safeguard against deadly plague

...odesign Institute at Arizona State University have successfully turned tobacco plants into vaccine production factories to combat the deadliest form of plague. The vaccine elicits a protective immune response in guinea pigs. The results are considered to be a milestone in the future development of a new vaccine f...

Face perception is modulated by sexual orientation

...ely adopt strategies of "face reading" in order to successfully interact with potential sexual partners. Thus, it is reasonable to assume differential patterns of activation in the hetero- and homosexual brains in response to faces of the same or opposite sex. In their new work, the researchers hypothesized that ...

Poison dart frog mimics gain when birds learn to stay away

...ance learning into account, says Cummings, you can successfully predict a specific direction of mimicry in evolution. In studying the toxicity and abundance of all three species, Darst found that the harmless frog mimics either toxic frog where they live separately. In the north, the mimic looks like the less to...
