DNA Molecules Used To Assemble Nanoparticles

...variety of molecules---drugs, contrast agents---to almost any cell," said Dr. James R. Baker Jr., the Ruth Dow Doan Professor of Nanotechnology and director of the Center for Biologic Nanotechnology at U-M. Nanoparticle complexes can be specifically targeted to cancer cells and are small enough to enter a ...

Wisconsin scientists grow critical nerve cells

...messages from the brain and spinal cord, dictating almost every movement in the body from the wiggling of a toe to the rolling of an eyeball. The new development could one day help victims of spinal-cord injuries, or pave the way for novel treatments of degenerative diseases such as amyotrophic lateral scle...

UCLA Study Shows One-Third of Drug Ads in Medical Journals Do Not Contain References Supporting Medical Claims

...icy or because it was proprietary. "We found that almost one-third of the pharmaceutical ads offered no references at all to support medical claims. In addition, most of the data-on-file documents in support of the medical claims were not available from the drug companies," said Dr. David Schriger, study a...

Ancient olfaction protein is shared by many bugs, offering new pest control target

..., one odorant receptor protein, Or83b, is found in almost all olfactory neurons and serves a general function in detecting odors. When the gene for Or83b is deleted, the flies can't smell. In the new study, Vosshall, in collaboration with researchers from Sentigen Biosciences, showed that the function of O...

New Technique for Tracking Gene Regulators

... known as CREB.“Though scientists have now decoded almost all of the entire humangenome ?the series of nucleotide bases (labeled A, T, G, and C) thatmake up the source code for running the machinery of the cell ?we arejust beginning to decipher it,?said biologist John Dunn, who ledBrookhaven’s role in the r...

U-M scientist to talk about tissue engineering at AAAS

... bones. That would help a patient develop new bone almost indistinguishable from nature's original equipment. Many researchers at University of Michigan have focused their tissue engineering efforts on the head and neck, in part because U-M Dentistry plays a leading role in the effort. Dentists have a long...

Scientists find missing enzyme for tuberculosis iron scavenging pathway

...e was also regulated by iron, was that Rv1347c was almost certainly a "missing enzyme" from the pathway for biosynthesis of the iron scavenging agent mycobactin," recalls Dr. Baker. "Mycobactin is a small molecule which binds iron very tightly. Bacteria synthesize it so that they can acquire the iron they ...

Researchers reveal the infectious impact of salmon farms on wild salmon

... 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, pink and chum salmon leave their natal rivers while still much smaller than your baby finger ?3 cm long ?and weighing only half a gram. "The young...

New Clues Add 40,000 Years to Age of Human Species

...nding the dawn of Homo sapiens. Since the 1980s, almost everyone agreed that our ancestors originated on the African continent, but they differed on when modern humans first evolved, how humans dispersed to populate the globe, and what happened when, or if, modern humans encountered other hominid species ...

Scientists rid stem cell culture of key animal cells

...em cells in the desired undifferentiated state for almost a year. Although the new work "dramatically reduces the possibility of contamination" from animal pathogens, Xu warns that the continued use of serum replacement and Matrigel means that contamination remains a concern. The ultimate goal, he says, wo...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

...l. "Parrots are unusual among birds, in that they almost without exception display fantastic colors but exhibit very little variation in color within a species ?at least in colors visible to us. Parrots in general may not be using color in the classic cases of mate choice or competitive ability," he said. ...

While it was discovered almost three decades ago thatroughened metallic surfaces could enhance Raman scattering signals byfactors of 1 million, this "surface-enhancement" effect has beendifficult to control, predict, and reproduce for practical sensingapplications. Now, Rice resea...

Researchers trace evolution to relatively simple genetic changes

... some freshwater sticklebacks have evolved to have almost no body armor. "It's rather like a military decision, to be either heavily armored and slow, or to be lightly armored and fast," Kingsley said. "Now, in countless lakes and streams around the world these low-armored types have evolved over and over ...

Scientists reveal molecular secrets of the malaria parasite

...hromosome ends) while the "housekeeping" genes are almost totallyunchanged. * Researchers showed that the parasite genes evolve mostrapidly when they are expressed in the mammal hosts (human/mouse). Thatmay represent a mechanism by the parasites to repulse the attack of thehost's immune system. * For the fi...

Scientists identify new model Of NK cell development

...immature CD56 cells," he adds. "This study raises almost as many questions as it answers," says Caligiuri, "Finding these nursery sites of NK cells is just the first step. We feel this is the first solid evidence supporting a new model of NK cell development, but we also know that more work needs to be don...

NJIT Presidential Award winner takes stem cell research another step

... 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 unique because she has had success in crafting the right environment for stem cells to grow into other cells," said William Hunter, c...
