Researchers offer proof-of-concept for Altered Nuclear Transfer

...t Whitehead Institute for Biomedical Research have successfully demonstrated that a theoretical--and controversial--technique for generating embryonic stem cells is indeed possible, at least in mice. The theory, called altered nuclear transfer (ANT), proposes that researchers first create genetically altered e...

University of Delaware researchers develop cancer 'nanobomb'

...ted in this area. There is plenty of work ahead to successfully translate this into clinical medicine." In addition to treatment, he believes nanotechnology can provide new tools for cancer diagnosis through the use of tiny nanosensors. "In the future, my vision is that people will have at-home kits that can d...

Dangerous tricksters: Some bacterie use immune cells to reproduce

... and lysosomes, and how the immune system normally successfully eradicates an infection despite all the tricks the... practically never happens that healthy humans are successfully infected by them.' ...

Magnetic probe successfully tracks implanted cells in cancer patients

...international research team for the first time has successfully tracked immune-stimulating cells implanted into cancer patients for treatment purposes. "In four of the eight patients, MRI revealed that the implanted cells weren't where they needed to be to be effective for treatment," says Jeff Bulte, Ph.D., an...

Scientists use stem cells to grow cartilage

Scientists from Imperial College London have successfully converted human embryonic stem cells into cartilag... to have formed new cartilage, showing they can be successfully transplanted in living tissue. The scientists also believe this technique could be used in cosmeti...

The dangerous legacy of lead

... and balances, which must be in place if we are to successfully fight off pathogens. Our continuing research is aimed at discovering how lead upsets the balance of cells charged with protecting us." Graduate student David G. Farrer, of the Department of Environment Medicine, who established that T cell function ...

Bare metal stents deliver gene therapy to heart vessels with less inflammation in animal studies

...erapeutic genes. In cell cultures, the adenovirus successfully delivered genes from alloy samples to animal arterial smooth muscle cells. In a second experiment using rodents, the researchers detected gene expression with significantly lower restenosis in the carotid arteries of animals with the experimental ste...

Free-energy theory borne out in large-scale protein folding

...e National Academy of Sciences. "Researchers have successfully combined computer modeling and experimental results in folding studies for small proteins, but this is the first effective combination for a large, multi-domain protein," said study co-author Kathleen Matthews, Dean of the Wiess School of Natural Sci...

Tuberculosis still a risk for patients receiving HIV drugs

...ng tuberculosis more than doubled if HAART did not successfully control their HIV. Patients were also more likely ...hey have minor levels of immune suppression or are successfully treated with HAART." Health care settings should also maintain strict control measures to prevent th...

DNA technique measures suitability of soil for onion crops

...ith the Laboratory for Nematology, Blgg managed to successfully combine the fundamental knowledge from the patent with state-of-the-art laboratory practice. The result is a practical test that conclusively demonstrates the presence of both the stem nematode and onion white rot. Both parties are continuing to wo...

Wild birds help to create human flu vaccine

...dlife come into close contact is the best hope for successfully preventing the spread of avian flu and protecting both people and animals. To contain this potential epidemic, prevention activities must include better management practices in farms, especially those that are small and open-air where domestic poul...

Odd energy mechanism in bacteria analyzed

Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry - an advance that may ultimately help shed light on the ecology of the world's oceans. The microorganism is SAR11, the smallest free living cell known and p...

Travelers can avoid jet lag by resetting their body clocks

...environment. Both bright light and melatonin have successfully been used in laboratory and field settings to "phase advance" (resetting the circadian clock earlier in time so that all the circadian rhythms of the body occur earlier) thereby helping people adapt to night shift work or to a new time zone following...

Targeted drug delivery achieved with nanoparticle-aptamer bioconjugates

...described at ECCO 13 show that these bioconjugates successfully and selectively adhered to PSMA-positive prostate cancer cells, while PSMA-negative cells were not targeted. This prostate cancer targeting was modeled using a microfluidic device and shown to occur under physiological fluid flow conditions that are ...

Researchers use 'trickery' to create immune response against melanoma

T-rays: New imaging technology spotlighted by American Chemical Society

...es. In conjunction with NASA, THz imaging has also successfully detected defects in space shuttle foam. Other T-ray applications could enable the label-free characterization of genetic material, detect a C-4 explosive hidden in the mail, and help researchers understand the complex dynamics involved in protein fol...

Diabetes researchers pioneer islet cell xenotransplantation in primate studies

...ory University and the Emory Transplant Center has successfully transplanted insulin-producing neonatal porcine islet cells into monkeys, a procedure the researchers say represents a promising intermediate solution to the critical supply problem in clinical islet cell transplantation. "Our work at the U of A and...

Living taste cells produced outside the body

... the body and for the first time have been able to successfully keep the cells alive for a prolonged period of time. The establishment of a viable long-term model opens a range of new opportunities to increase scientists' understanding of the sense of taste and how it functions in nutrition, health and disease. ...

Liquid ventilation

...ults have been very good. It has even been applied successfully in more than 80 death-threatening situations in premature babies. But the perfluorocarbon for medical use is not available on the market. As premature babies need very small quantities and no commercial application for adults has been found, the pate...

Mouse study reveals human X-SCID gene therapy poses substantial cancer risk

...therapy, and of the 10 children treated, nine were successfully cured of X-SCID, although cancer was diagnosed in three of the children. Halted for a time, the trial is now continuing on a case-by-case basis, according to Woods. In the studies leading up to the human clinical studies, mice were studied post-tran...
