New comparative toxicogenomics database
Scientists at St. Jude Children's ResearchHospital have discovered that the shape of a protein on the surface ofpneumonia bacteria helps these germs invade the human bloodstream. Thisfinding, published Dec. 16 online by the EMBO Journal, could helpscientists develop a vaccine that is significantly more effective atprotecting children against the disease. The St. Jude researchersdetermined t...Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss
Ophthalmologists at Rush University Medical Center implanted Artificial Silicon Retina (ASR) microchips in the eyes of five patients to treat vision loss caused by retinitis pigmentosa (RP). The implant is a silicon microchip 2mm in diameter and one-thousandth of an inch thick, less than the thickness of a human hair. Four patients had surgery Tuesday, January 25. The fifth patient is sch...Ophthalmologists implant five patients with artificial silicon retina microchip

A new study has found that close to half of 154 smokers who had surgery to remove early stage lung cancer picked up a cigarette again within 12 months of their potentially curative operation, and more than one-third were smoking at the one year mark. Sixty percent of patients who started smoking again did so within two months of surgery. The study, led by researchers at Washington Univers...Nicotine triggers the same brain reward circuitry as opiates
In experiments with mice, researchers have found that nicotine triggers the same neural pathways that give opiates such as heroin their addictively rewarding properties--including associating an environment with the drug's reward. However, unlike opiates, nicotine does not directly activate the brain's opiate receptors, but activates the natural opioid reward pathway in the brain. The rese...ES Cell Characterization Kit from CHEMICON
Description:The ES Cell Characterization Kit consists of two components used for alkaline phosphatase activity determination as well as four ES cell-specific antibodies required to perform 100 tests (including controls). • Stem cells have become the subject of extensive investigation recently, partly due to their therapeutic potential and because they raise several fundamental issues concerning the regu...In Vitro Osteogenesis Assay Kit from CHEMICON
Description:CHEMICON's In Vitro Osteogenesis Assay Kit contains all reagents necessary to efficiently differentiate MC3T3-E1cells to a mature osteoblastic lineage, as determined by staining for mineralization. In addition this kit provides all the necessary reagents and a protocol for quantifying osteogenesis using a standard plate reader. This product is useful for studying the effects of growth factors, dr...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...Freund's Complete Adjuvant from CHEMICON

First it was the nicotine patch, then came the gum, inhalers and other products intended to help smokers kick the habit by getting over their nicotine fixation. The new kid on the block in this ever increasing list is a nicotine solution that can be mixed with drinks, which scientists claim could be useful in over coming the addiction. Researchers at Duke University have tested and pate...Cervicogenic headache can be identified with a fibromyalgia test
Findings from a new study presented at the 19th Annual Meeting of the American Academy of Pain Medicine by the Medical Director, John McFadden, MD, of the Tupelo Pain Clinic, Mississippi stated that patients with severe headache could benefit from an upper-body fibromyalgia examination to determine if the headache is potentially cervicogenic. According to Dr. McFadden many headaches of ce...FDA considers nicotine lollipops illegal
The Food and Drug Administration cracked down on Internet distributors of nicotine-laced lollipops and lip balm, declaring them illegal and ordering that 4 pharmacies stop sales immediately. The lollipops in particular pose a risk to children because they look like regular candy, the FDA warned. "The quantity of nicotine could be potentially dangerous to a small child," said FDA attorney...Lexicon Pharmaceuticals and Fox Chase Publish Findings on Immune Deficiency
