Yellowstone microbes fueled by hydrogen, according to U. of Colorado study
Microbes living in the brilliantly coloredhot springs of Yellowstone National Park use primarily hydrogen forfuel, a discovery University of Colorado at Boulder researchers saybodes well for life in extreme environments on other planets and couldadd to understanding of bacteria inside the human body.A team of CU-Boulder biologists led by Professor Norman Pace, one ofthe world's leading expe...Color-blind method opens new doors in DNA sequencing
A "color-blind" method of fluorescence detection developed by researchers at Baylor College of Medicine (BCM) and Rice University could open new doors that would take DNA sequencing to the patient's bedside, the doctor's office and even the scene of a crime or a battlefield. "We could eventually do direct detection of a DNA sequence from native DNA" without manipulation now performed in th...ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors
Parrots, long a favorite pet animal, are attractive to owners because of their vibrant colors. But those colors may mean more to parrots than what meets the eye. For more than a century, biochemists have known that parrots use an unusual set of pigments to produce their rainbow of plumage colors, but their biochemical identity has remained elusive. Now, an Arizona State University researc...Scientists develop new color-coded test for protein folding
Every protein--from albumin to testosterone --is folded into a unique, three-dimensional shape that allows it to function properly. Now Stanford University scientists have developed a simple test that instantly changes color when a protein molecule attached to a gold nanoparticle folds or unfolds. The new technique, which works on the sa...New insight into people who 'see' colors in letters and numbers
People with a form of synesthesia in which they see colors when viewing letters and numbers really do see colors, researchers, led by Edward M. Hubbard of the University of California San Diego, have found. What's more, functional magnetic resonance imaging (fMRI) of their brains reveals that they show activation of color-perception areas. The researchers said their findings lend support t...Glutathione-S-Transferase (GST) Colorimetric Assay Kit from Sigma-Aldrich
Description:Biochem/physiol Actions: Glutathione-S-transferases (GSTs) are a group of enzymes important in the detoxification of many xenobiotics in mammals. The enzymes protect cells against toxicants by conjugating the thiol group of the glutathione to electrophilic xenobiotics, and thereby defend cells against the mutagenic, carcinogenic, and toxic effects of the compounds. GST activity is presen...Mast Cell Degranulation colorimetric Assay Kit from CHEMICON
Description:Degranulation, the secretion of cytoplasmic granules, is a key step in the inflammatory response of leukocytes (e.g. basophils, neutrophils, eosinophils, and mast cells). In addition to histamine, these secretory granules contain many proinflammatory mediators including heparin, cytokines, chemokines, and many proteases (Hallgren, 2001). Tryptase, a tetrameric serine proteinase, has emerged as th...One-Color RNA Spike-in Kit from Agilent Technologies
Description:The Agilent One-Color RNA Spike-In Kit contains in vitro synthesized, polyadenylated transcripts that specifically anneal only to complementary control probes on Agilents microarrays, with minimal self- or cross-hybridization. The spike-ins serve as a positive microarray control in the hybridization protocol. * NOTE: This kit is a required component of the Agilent One-Color Gene Expression p...Two-Color RNA Spike-in Kit from Agilent Technologies
Description:The Agilent Two-Color RNA Spike-In Kit contains in vitro synthesized, polyadenylated transcripts that specifically anneal only to complementary control probes on Agilents microarrays, with minimal self- or cross-hybridization.

Description:It has been demonstrated that oxidative stress is involved in atherosclerosis, chronic inflammatory disease, and cancer. Oxidative stress is the condition in which an imbalance between oxidant stimuli and physiological antioxidants exist leading to the damage of a cell. The bodys physiological response to oxidative stress is through several antioxidant systems4 that include enzymes and varying si...What color is your CEO's parachute?
Okay, before I get all lathered up about the latest outrages in the CEO suite, let me assure you that I recognize completely that the majority of top executives are honest and good people trying their best to lead their organizations to success. And that the CEO's I will be talking about represent the extreme of executive limit pushing. Still, these are people who w...Colorectal Cancer Can Be Detected By a Simple Test
The immunochemical faecal occult blood test (FOBT) is a simpler way of identifying individuals who might have colorectal cancer, researchers claim in an article published online in The Lancet Oncology.// Conventionally, guaiac FOBT is used to screen individuals who might be having this cancer, but this new test "could decrease substantially the number of false positives in a screening programme f...Early detection of colorectal cancer may be hindered by coloured toilet disinfectants
A new study published in the British Medical Journal has argued that the cause of failure in detecting colorectal cancers at an early stage could be attributed to coloured toilet disinfectants. Researchers claimed that nine out of ten bowel and colon cancers detected early can be successfully treated and that once the cancer has spread cure rates drop dramatically. The National programme// for de...Screening Test For Early Diagnosis Of Colorectal Cancer
Colorectal cancer is the second leading cause of cancer death in the United States, partly because it is often detected at advanced stages. // Screening reduces death by detecting cancers earlier when they are more curable. A new study shows primary care providers do not screen all eligible patients for colorectal cancer. Researchers attribute the limited use of these tests to four fact...L'Anthony New Color Test 100 Hue Test
