SPR microscopy examines binding kinetics of membrane proteins

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers - early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.

Refrigerating coal-plant emissions would reduce levels of dangerous chemicals in air

Refrigerating coal-plant emissions would reduce levels of dangerous chemicals that pour into the air -- including carbon dioxide by more than 90 percent -- at a cost of 25 percent efficiency, according to a simple math-driven formula designed by a team of University of Oregon physicists.

More than 40 plant-based compounds can turn on genes that slow the spread of cancer

More than 40 plant-based compounds can turn on genes that slow the spread of cancer, according to a first-of-its-kind study by a Washington State University researcher.

Study investigates effects of passive smoking on the levels of three parameters

"It is well known that passive smoking is harmful for cardiovascular health, but the mechanism has not yet been discovered," said Dr Kaya. "We investigated the effects of passive smoking on the levels of three parameters - mean platelet volume (MPV), carboxyhemoglobin (COHb) and lactate - in an effort to further understand this mechanism. We also looked at the correlation between the three parameters."

Diet and exercise help protect astronauts' bones in space

Eating the right diet and exercising hard in space helps protect International Space Station astronauts' bones, a finding that may help solve one of the key problems facing future explorers heading beyond low Earth orbit.

TREM-1 gene disrupts inflammatory process implicated in liver cancer

Researchers at the Georgia Health Sciences University Cancer Center have identified a gene that disrupts the inflammatory process implicated in liver cancer.

Evidence stacks up against bisphenol A

High levels of urinary bisphenol A may be linked to severe coronary artery stenosis, report researchers in PLoS One.

Study identifies certain small molecule chemicals that can disrupt quorum sensing in A. baumanni

Acinetobacter baumanni, a pathogenic bacterium that is a poster child of deadly hospital acquired infections, is one tough customer.

Chemists develop new lab test to examine how DNA damage disrupts protein synthesis

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.

Platelet-like nanoparticles nearly double survival rate after internal injury

Nanoparticles tailored to latch onto blood platelets rapidly create healthy clots and nearly double the survival rate in the vital first hour after injury, new research shows.

Secondhand smoke exposure decreases sensitivity to cough-eliciting respiratory irritants in children

New research from the Monell Center reveals that exposure to secondhand smoke decreases sensitivity to cough-eliciting respiratory irritants in otherwise healthy children and adolescents.

New evidence reveals possibility of mood-enhancing effects associated with some flavors

New evidence reveals the possibility of mood-enhancing effects associated with some flavors, stemming at least in part from natural ingredients bearing a striking chemical similarity to valproic acid, a widely used prescription mood-stabilizing drug, scientists reported here today. This effect joins those previously reported for chocolate, teas and some other known comfort foods.

New birth-control strategy for mosquitoes can combat malaria

Using information about the unique mating practices of the male malaria mosquito ― which, unlike any other insect, inserts a plug to seal its sperm inside the female ― scientists are zeroing in on a birth-control drug for Anopheles mosquitoes, deadly carriers of the disease that threatens 3 billion people, has infected more than 215 million and kills 655,000 annually.

Study examines shared traits of cancer cells and bacteria

Experts agree that, more than ever before, modern wars will be fought in the cyber zone, targeting an enemy's communications technology to cause untold damage. Now a Tel Aviv University researcher is suggesting that the same tactics should be employed in the battle against one of the body's deadliest enemies - cancer.

Boys are little more susceptible to both bad and good exposures

A new study is the first to find a difference between how boys and girls respond to prenatal exposure to the insecticide chlorpyrifos. Researchers at the Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health found that, at age 7, boys had greater difficulty with working memory, a key component of IQ, than girls with similar exposures.

Scientists develop new way to study role of GABA-A receptors in various disorders

A new way to study the role of a critical neurotransmitter in disorders such as epilepsy, anxiety, insomnia, depression, schizophrenia, and alcohol addiction has been developed by a group of scientists led by Gong Chen, an associate professor of biology at Penn State University.

VA agrees to move forward on CT screening for veterans at high risk for lung cancer

Today, Lung Cancer Alliance (LCA) announced that the Department of Veterans Affairs (VA) has agreed to move forward on CT screening for veterans at high risk for lung cancer. This was communicated to Laurie Fenton Ambrose, LCA President & CEO in written correspondence by VA Under Secretary for Health Dr. Robert A. Petzel.
