Carbon nanotube absorption measured in worms, cancer cells
University of Michigan researchers have discovered how to measure the absorption of multi-walled carbon nanoparticles into worms and cancer cells, a breakthrough that will revolutionize scientists' understanding of how the particles impact the living environment. A team led by U-M chemical engineering professor Walter J. Weber Jr. tagged multi-walled carbon nanotubes---one of the most pro...Phosphorescence lifetime measured using the SPEX phosphorimeter
A phosphorimeter integral to the SPEX system can uncover important information on various systems of chemical and biochemical interest, by revealing data normally masked by intense but rapid fluorescence. <P>This Application Not...Response to chemotherapy could be measured by Prostate-Specific Antigen Doubling Time
Researchers from the department of urology in a hospital in Switzerland who investigated whether chemotherapeutic response to hormone-refractory prostate cancer could be measured via changes in prostate-specific antigen (PSA) found that prostate cancer doubling time may be an auxiliary marker of response to chemotherapy// in patients with hormone refractory prostate cancer. The study...Absorption Of Carbon Nanotube Measured In Worms Revolutionize Cancer Research
Researchers from the University of Michigan have discovered how to measure the absorption of multi-walled carbon nanoparticles into worms and cancer cells. // Carbon nanotubes were discovered in 1991, and have a great value in several areas, including pharmacology and for hydrogen storage in fuel cells. But despite their promise, a big problem was that it's not known how multi-walled carb...Adherence to Dietary Recommendations Measured
A new way of measuring how closely people follow dietary recommendations contained in tools like the Food Guide Pyramid and the new MyPyramid have been deveoped by researchers at the University of Alabama.// According to them young children's adherence to the recommendations decreases as the children get older. The dual purposes of the study were to develop and test the potential us...Severity of heart failure in elderly can be measured with a seven-point system
Seven pointers that are fairly easy is gaining credibility in assisting the treatment of elderly patients who have suffered heart failure. //Researchers at Washington University School of Medicine in St. Louis have suggested that by simply counting the number of health factors to a patient's advantage, the physician can use this barometer to assess the patient's risk of death. The po...Individuals Distraction can Be Measured by a Computer Based Test
A psychologist at the University College London has designed a computer based test that may reveal how easily an individual can be distracted. Professor Nilli Lavie claims that her scientific test can be used as another assessment tool during the recruitment process, and may be beneficial in fields where employee distraction can lead to fatal errors. "When you are eas...
