Honey helps problem wounds

...ntly being formed from the sugar in the honey. The advantage over the hydrogen peroxide from the chemist's is that small concentrations are sufficient to kill the germs, as it is constantly being produced. As a rule much larger quantities of hydrogen peroxide would have to be used, as hydrogen peroxide loses i...

Technique speeds up detecting, treating wound bacteria

...ust what bacteria they're dealing with. "The big advantage of real-time PCR is that we get quantitative information and accurate identification on the organisms in five hours or so, whereas the current procedure--culturing and identifying organisms by biochemical activity, etc.--can take one to several days ...

Delft water-purification method promises radical improvement

...med in the water that is to be purified. The great advantage of these granules is that they sink quickly and that all the required biological purifying processes occur within these granules. The technology therefore offers important advantages when compared to conventional water purification processes. For ex...

How can identical twins be genetically different?

...M Medical School and co-author of the study. The advantage of studying twins is that they start out with the exact same genetic information. Therefore, differences in gene expression are attributable to different environmental factors rather than genetics. Such factors could cause a random genetic mutation o...

Radiation-killed bacteria vaccine induces broad immune response in mice

...ted bacteria also may not need to be kept cold; an advantage in settings where refrigerating vaccines is impractical or impossible. A report on the research appears in the current issue of the journal Immunity. In experiments with mice, scientists including Eyal Raz, M.D., Sandip Datta, M.D., and Joshua Fi...

Nanowire arrays can detect signals along individual neurons

...as well as single viruses. Their latest work takes advantage of the size similarities between ultra-fine silicon nanowires and the axons and dendrites projecting from nerve cells: Nanowires, like neuronal offshoots, are just tens of nanometers in width, making the thin filaments a good match for intercepting n...

Buckyballs boost antibody's chemotherapy payload

... one Taxol per buckyball is exciting, but the real advantage of fullerene immunotherapy over other targeted therapeutic agents is likely to be the buckyball's potential to carry multiple drug payloads, such as Taxol plus other chemotherapeutic drugs," said Rice's Lon Wilson, professor of chemistry. "Cancer cel...

Teasing out tissue from blood

...at can be implanted to heal damaged tissue. A huge advantage over using donated tissue is that the transplant would be "autologous" ?made of the patient's own cells, thus avoiding immune rejection. "It's autologous, we don't need to worry about rejection of tissue, and immunosuppression," says Glenn Winnier o...

New GI technologies improve internal organ visualization

...enter and lead study author. "Clearly, DBE has the advantage of being able to treat problems. But we believe that based on the results of this study, CE should continue to be used as a valuable regular screening test for bowel abnormalities, while DBE will be a better procedure for conformation and treatment ...

Study reveals details of mussels' tenacious bonds

...rial buildup. "For example, we may be able to take advantage of the reactivity of oxidized DOPA to form covalent bonds between adhesive DOPA-containing polymers and human tissue surfaces." ...

Fatty spheres loaded with siRNA shrink ovarian cancer tumors in preclinical trial

... no electrical charge. Its neutrality provides an advantage over positively or negatively charged liposomes when it comes to binding with and penetrating cells. The next step for the FAK siRNA-DOPC liposome is toxicity testing. "So far it appears to be very well-tolerated," Sood says. "We hope to develop t...

Encoded metallic nanowires reveal bioweapons

...the sample contains anthrax spores. One particular advantage of nanowires over other antibody supports is that the tests do not take place at a surface but instead in a suspension, which makes them run much faster and more accurately. If nickel stripes are also added to the ends of the wires, they can then be ...

Tumor wizardry wards off attacks from the immune system

...he scientists discovered that cancerous cells take advantage of T-reg cells' suppressor ability, enlisting them to keep the immune system at bay. Their report appears in the July/August issue of the Journal of Immunotherapy. "Earlier, we found that T-reg cells are much more prevalent in patients with breast c...

Scientists reverse evolution

...ist because they perform a new job that holds some advantage for allowing an organism to adapt. The quadrupling... a half-billion years ago provided animals with an advantage "because they had more genes to use for specialized jobs," including adapting to environmental chang...

UCSD researchers develop 'smart petri dish'

...performed in real time, representing a significant advantage compared to other techniques for in vitro monitoring of cell morphology," that is, for monitoring cells in the laboratory, outside of humans or animals. ...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...ience here is necessary," says Griffiths, "to take advantage of the possible benefits psilocybin can bring to our understanding of how thought, emotion, and ultimately behavior are grounded in biology." Griffiths is quick to emphasize the scientific intent of the study. "We're just measuring what can be obs...

Researchers appeal for new regulations to save coral reefs from live fish trade

...nt laws to regulate the poaching. The bandits take advantage of porous world trade policy and ineffective fisheries management to sell their plunder," says Dr Helen Scales, from the Department of Zoology, University of Cambridge. By analysing the mass of live fish imported into Hong Kong from various source ...

Biofuels researcher searches for new sources

...erintendent of the Central Ag Research Center "The advantage of using annual farm crops for ethanol production is that farmers can produce biomass with conventional crops and equipment, and can alternate crop production for energy, food or feed," he added. In areas with irrigation and enough heat, a double-c...

Innovative method for creating a human cytomegalovirus vaccine outlined

...otavirus backbone. The vaccine that resulted takes advantage of the immunological characteristics of both the human and bovine viruses. This approach is conceptually similar to Maul's strategy for developing a CMV vaccine, although the recombinant technologies available today should help to streamline the task...
