Modified collagen could yield important medical applications

...es and observed the glow in collagen that had been mixed with the smaller molecules. Exactly how and why the collagen and the peptides join is uncertain. But researchers know that collagen molecules form a distinctive triple-helix in which three long protein strands intertwine like rope. Yu speculates that...

NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...rain and skin. Eight other patients demonstrated a mixed or minor response. Of the 18 patients showing improvement, 15 had a partial response that lasted from two months to more than two years. It is noteworthy that there were three (9 percent) patients who continued to experience complete disappearance of...

Stealth Worms May Improve Insect Pest Control

...d in a gelatinous matrix, or dried in powder, then mixed in water and sprayed, broadcast or irrigated onto crops. Large numbers of infectious juveniles are released to inundate and kill the pest insects quickly. Depending on climate conditions, this method works best on greenhouse ornamentals and vegetabl...

Science study holds implications for gene therapy and stem cell biology

A study in the May 20 issue of Science holds mixed blessings for scientists who follow research in gene therapy and stem cell biology. The study, conducted by scientists from Cincinnati Children's Hospital Medical Center, and Hannover Medical School and Hamburg University in Germany, reveals importan...

U-M team recovers ancient whale in Egyptian desert

...mple as an intravenous infusion of saline solution mixed with trace amounts of an agent that would interfere with the body's ability to use oxygen, Roth said. Using oxygen deprivation to depress metabolic activity also might extend the amount of time that organs and tissues could be preserved outside the ...

Gene therapy promising for growing tooth-supporting bone

...th development and periodontal repair. This study mixed BMP-7 genes with an inactivated virus in a gel-like carrier and injected it into wounds. Giannobile said using a virus, with the harmful effects turned off, harnesses the virus' ability to enter into cells and use their genetic machinery. Once insid...

Biodiversity hotspots identify conservation priorities

...ion and fragmentation. The latest analysis offers mixed news about existing hotspots. On one hand, some hotspots have deteriorated significantly: a notable example is Southeast Asia's Sundaland, whose forest loss has been driven largely by extensive commercial logging and agricultural projects. On the oth...

Children's taste sensitivity and food choices influenced by taste gene

...ome cases modified by age. In individuals with the mixed AP genotype, children were more sensitive to bitter than adults, with 64% of children but only 43% of adults able to detect bitterness in the weakest PROP solution. "This type of information will one day help to improve the diets of our children by ...

NJIT Presidential Award winner takes stem cell research another step

...ell discoveries: One showing that stem cells, when mixed with biomaterials known as scaffolds, can help regenerate bone growth; and another proving 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...

Purdue proves concept of using nano-materials for drug discovery

...e liquid diffused through the membrane's pores, it mixed with the enzyme, causing a reaction and turning blue in the process, which demonstrated that the device works. The Center for Membrane Protein Biotechnology combines a diverse range of researchers, from engineers to chemists, and pharmaceutical scie...

Researchers reveal the infectious impact of salmon farms on wild salmon

...ivers and head to sea, traveling en masse in large mixed schools. Thus the scientists could see the effect on the salmon as they moved toward the farm. They found that the juvenile salmon carried almost no sea lice prior to the farm but became heavily infected as they approached it. Unlike other species, ...

Timing is everything: First step in protein building revealed
