Acid-rain component may be more potent pollutant than previously thought, UB chemists discover

...e generated when the nitric oxide/ethanol clusters react with sunlight. In the laboratory, the UB team used laser light to generate mixed gas-phase clusters of nitric oxide/ethanol and used mass spectrometry to confirm that photochemical reactions were occurring. In fundamental terms, the findings also pro...

Job stress may lead to back injury for some people, study finds

... Why would introverts and intuitors react so strongly? According to psychologists, introverts commonly internalize feelings of frustration, while intuitors tend to dislike repetitive tasks. The authors speculated that introverts may...

Secrets hidden in a tiger's paralyzing roar

...ng audible and infrasounds, the tigers appeared to react to these sounds. Sometimes they would roar and leap towards the speakers and sometimes sneak away. The next step for von Muggenthaler is to take the recorded infrasounds to scientists who can determine whether or not tigers can hear the infrasounds...

Aslera™ improves bone mineral density in lupus patients

...Officer. Lupus patients develop antibodies that react against their own normal tissue, which can lead to inflammation, arthritis pain, tissue injury and major organ damage. In addition to the risk of osteoporosis from age and steroid drug therapy, lupus patients can experience disease symptoms including...

Aslera™ improves lupus disease activity and symptoms

...od. In lupus, the body develops antibodies that react against a person's normal tissue, which can lead to inflammation, arthritis pain, tissue injury and major organ damage. Common signs and symptoms of disease that lupus sufferers experience - severe fatigue, arthritis, facial rash, fever, seizures, he...

UCSF researchers reveal a fundamental decision-making unit of cells

... from microbes to humans depends on the ability to react to changing conditions, and scientists have already described many of the responses made constantly by every cell of the body. But the mechanisms by which these decisions are made has been unclear. How, for example, does a white blood cell detect the...

MS clinical trials confirm approach, demonstrate need to carefully refine targeted peptide therapy

...rm of MBP into MS patients might cause the body to react to the normal MBP in a protective way instead of a harmful way, thereby stopping flare-ups of the disease. In the first study, researchers led by Roland Martin, M.D., of the National Institute of Neurological Disorders and Stroke (NINDS) Cellular Imm...

Major air pollution study launched

...ese data to study how the chemicals mix, move, and react in the atmosphere under a variety of meteorological conditions. Ozone, one of the pollutants under study, is formed from reactions between sunlight and nitrogen oxides and/or hydrocarbons, such as those emitted from power plants and automobiles. ...

UC Irvine molecular biologists discover key protein interaction that stabilizes cholesterol levels in cells

New robotic microarray technology finds novel genes involved in cardiac hypertrophy and recovery

...kinds of tissues was mixed together and allowed to react with the thousands of gene-fragment strands on the microscope slide. A laser scanner excited the dyes. A spot that glowed more red than green marked a gene that was active at that stage of hypertrophy or recovery. A spot that glowed green marked a g...

$11-million grant supports study of how genes affect cancer chemotherapy

... cup of coffee, to predetermine how patients would react to the drug and to calculate the best dose for each patient. More recently he has focused on genetic variation in the enzymes that metabolize a powerful and widely used anticancer drug known as CPT-11 , or Camptosaur, which has proved effective agai...

Rockefeller University researchers discover immune-cell mechanism that boosts therapeutic antibody potency

...to the other end of the antibody." These receptors react to the antibody in pairs, much like a switch that turns the immune response on or off: one receptor activates an immune response and another inhibits it. When an antibody encounters a tumor cell and engages an effector cell through its Fc portion, i...

Manatees saved by ONR-supported technology

Funding for the project was awarded through ONRs Small Business Innovation Research Program. Additional funding was provided by the Defense Advanced Research Projects Agency. A piezoelectric materia...

Detroit researcher receives national award

...es at which molecules he has built, called probes, react with P450. His group uses short bursts of laser light to 'time' the reactions. "His work has electrified the P450 area," wrote Dennis Curran of the University of Pittsburgh to second the award nomination. "Marty has proposed completely new mechanisms...

Tiny proteins may unleash big victories over cancer through new $10 million U-M tumor research effort

...in blood. Past research hasshown that the body can react to new cancer cells as if they were invadingorganisms, and that this immune response leaves behind tumor-specific antibodiesthat can be detected in the bloodstream long before a tumor has grown largeenough to be found. Or, the blood might contain pro...
