Red wine mist? Resveratrol shows potential effects against COPD, asthma, arthritis

...don't know what its target receptor is as it binds like a protein, but acts like an estrogen," which it's not. "The good thing is that it does stop inflammation" across a broad rang...

Fly gut's 'sticky spot' for leishmaniasis parasite

Insect-borne parasites usually like to "stick" around inside their hosts while they mature and prepare to infect again. Now, Jesus Valenzuela and colleagues have identified the molecular receptor inside the midgut of the sand fly Phlebotomus papatasi that provides the "flypaper" for th...

Research to explore revolutionary gene sequencing: Threading the molecular needle

... first assembled around a long, straight molecule, like beads on a wire. The "wire" molecule is then attached to a surface at one end, and to the end of a DNA molecule at the other by chemical bonds. The AFM tip bonds to the "bead" and by its movement rapidly pulls first the "wire" and then the DNA molecu...

'Broken' gene reveals evolution of salt retention and possible ties to hypertension

...maged versions of genes that cause rare disorders, like cystic fibrosis or phenylketonuria. Now, we are starting to look for common genes that may have been beneficial in an environment of scarcity, but have become harmful in a world of plenty. In the modern setting, it may often be the genes that aren'...

Hurricane damage creates pecan shortage

...re is an extended period of cool, wet weather much like the weather caused by the hurricanes. The disease causes the kernel to discolor and rot, rendering it inedible. "The appearance of this disease has really compounded the situation," said Brenneman. Plant health specialists are working with growers to...

Actin muscles in on DNA transcription

..."Whenever cells move or divide, actin is involved, like its partner myosin." "But in the nucleus," de Lanerolle said, "actin acts instead like a binding protein. It recruits other proteins in the very complicated process our bodies use to tran...

Gimli gobblers Mercury scientists to conduct unique human experiment next week

...ed research they're conducting. "Being guinea pigs like this takes us back to our roots," says Dr. Lucotte. "It's important for us to remember that we're not just working on a hypothetical story, we're working with real people and real passions. And that we ourselves can be exposed to mercury in our diets...

Sick kids researchers unmask the potential of stem cells found in adult skin

...nic stem cell called a neural crest stem cell, and like neural crest stem cells, are endogenous and multipotent in nature. These neural crest stem cells generate the peripheral nervous system, and we are therefore now confident that we can make neural and other types of cells from the stem cells found in ...

Gene that blocks free radical damage protects against emphysema

...d in mice the nuclear factor, erythroid-derived 2, like 2 (Nrf2) gene, which makes a protein that regulates genes involved in protecting the body from free radical damage. The authors found that cigarette smoke-induced emphysema was of earlier onset and more widespread in the Nrf2/ mice than in their wild...

Researchers unlock mysteries of toxic metals in the largest contaminated site in United States

...rate that takes up lead, arsenic, copper, and zinc like a sponge. We hadn't even known it was there." The researchers also found another iron oxide mineral that is well known, ferrihydrite, that had been thought to be the most active phase for taking up the contaminant metals. " And we found other minera...

Hurricane Ivan helps student study sinkholes

...hat water was not sinking evenly or being taken up like a sponge, but that there are preferential flow paths." Next, he will create a 3-D model by placing the electrodes in a grid, which will allow him to add the direction of water movement to his model. He combines the electrical resistivity measurements...

Initial sensor for p53 tumor-suppressing pathway identified

...lves, then, are tightly packed together - possibly like a stack of coins, Halazonetis suggests - to form the dense chromatin. When all is as it should be with the DNA, a target site for 53BP1 lies at the center of each of the stacked nucleosome disks and is not available for binding. "But if you have a DN...

Researchers grow sperm stem cells in laboratory cultures

To conduct their study, Dr. Kubota and his colleagues began with mice that had been genetically altered to express green fluorescent protein, or GFP, which gives off a green light in the presence of a certain w...

Research team discovers possible genetic mechanism behind congenital heart defects

You can see the same sort of trends in the evolution of prot...
