Health costs soar as 60 million Americans classed as obese

...ded RNA. Through specific chemical reactions, they attach two strands of DNA, each resembling one side of a ladder. The two DNA strands spontaneously bind together, then the researchers add magnesium ions to initiate folding of the RNA. "Folding of the RNA structure competes with formation of the DNA const...

Purdue scientists may have found key to halting spinal cord damage

...nts - such as vitamins C and E - which are able to attach themselves to free radicals, detoxifying them. While there is nothing inherently wrong with this approach, Shi said, it might not be getting at the root of some health problems. "Antioxidants are good scavengers of free radicals, and it's certainly ...

Scientists discover that three molecules may be developed into new Alzheimer's drugs

...said Kosik. "This means that many phosphate groups attach to tau--modify it--and cause it to become dysfunctional." The culprit is an enzyme, called CDK5, that attaches the phosphate to the tau protein, facilitating the disease process. The researchers set out to find a way to inhibit this enzyme, to keep ...

Promiscuous Catalytic Activity Possessed by Novel Enzyme Structure

...l number of molecules, this new enzyme was able to attach prenyl groups to most of the different aromatic compounds tested. Some of the newly-formed hybrid molecules had previously been found in natural sources, but the enzyme also built some new compounds that had never been seen before. The key to Orf2’s...

Gene therapy advance treats hemophilia in mouse models

...ified virus. This hybrid vehicle could more easily attach to certain liver cells and allow the genes within the vehicle to enter the cells. The genes then caused the liver cells to make the protein that prevents bleeding. The researchers also modified the vehicle so that it would express these therapeutic...

New lead reported in tumor angiogenesis

... trigger angiogenesis, tumor cells also physically attach to a protein displayed on the surfaces of cells that line the walls of our blood vessels. This physical interaction, like a finger pushing a button, sends a signal within these cells to grow and sprout new capillaries. The finding, while technical i...

Secrets to antibody's success against West Nile Virus surprise scientists

New technique rapidly detects illness-causing bacteria

...ther sequence of the S. pyogenes rRNA. The probes attach to the target rRNA sequence when the test tube is placed in a water bath for about 25 minutes at exactly 41 degrees Celsius (106 Fahrenheit). At that temperature, the complementary probe DNA sequence binds to the target RNA sequences. In a positive ...

Tagging pathogens with synthetic DNA 'barcodes'

...g cells consists of two complementary strands that attach to one another along their length. But Luo's research purposely and completely ignores the DNA's genetic coding properties. He uses DNA, he said, as a "generic instead of a genetic material." By synthesizing three short strands of DNA, each of which...

Krishnan was able to identify the precise segment at which the prions interact--something that no one had done before him with a real prion. To do this, Krishnan took a variety of yeast prion strains and modified them in such a way th...

Pol III copies the original DNA, and acts as a proofreader to catch any misspellings and cuts any base that is wrong. But Pol III is a perfectionist, and can stall if it encounters a problem. Pol...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

..."For instance, the splice leader of the mRNA might attach at the turret, which may swivel out and drag the mRNA across the binding site on the ribosome to initiate protein translation." The findings may also advance studies of parasitic relatives Trypanosoma brucei, which causes sleeping sickness in Africa...

The mutation response method employed by our adaptive immune system seems keyed to this number, producing antibodies that are statistically likely to mistakenly bond with healthy proteins slightly less than o...
