Clam embryo study shows pollutant mixture adversely affects nerve cell development
A scientist at the Marine BiologicalLaboratory (MBL) has published the results of an EPA-funded clam embryostudy that supports her hypothesis that, when combined, the pollutantsbromoform, chloroform, and tetrachloroethylene--a chemical cocktailknown as BCE--can act synergistically to alter a key regulator in nervecell development. While scientists have previously studied the effectsof these...New Mixing Method for Microchip-Sized Labs
"Because up to 75 percent of breast cancerpatients have an abnormality in a specific cell signaling pathway,drugs that target different molecules along that pathway may beespecially effective for treating the disease, says a researcher fromThe University of Texas M. D. Anderson Cancer Center." A clearer picture is now emergingabout the importance of the phosphatidylinositol 3 kinase...After a time-shift, mixed signals from the circadian clock
Circadian rhythms in mammalian behavior, physiology, and biochemistry are controlled by the central clock within a brain structure known as the suprachiasmatic nucleus (SCN). The clock is synchronized to environmental cycles of light and dark. It is well known, from everyday experience, that adjusting to new light schedules takes several days, though the details of how this adaptation takes place...Multiple genes permit closely related fish species to mix and match their color vision
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using photoreceptors that are attuned to particular wavelengths of light. By studying a special group of closely-relat...Sea slug mixes chemical defense before firing at predators
When threatened by predators, sea slugs defend themselves by ejecting a potent inky secretion into the water consisting of hydrogen peroxide, ammonia and several types of acids. A team of researchers with the Atlanta-based Center for Behavioral Neuroscience (CBN) has found that this secretion is produced from normally inert chemicals stored separately in two glands. The discovery, published in th...Nutrient Mixture F-12 Ham, Coon's Modification (Ham's F-12 Coon's) from Sigma-Aldrich
Description:Coon's Modification of Ham's F-12 was developed for culturing hybrid cells that were produced by viral fusion. The modification consists of doubling the amino acids and pyruvate, and including ascorbic acid. The salt concentrations have been altered as well. This formula contains 0.863 mg zinc sulfate per liter, which may render it unsuitable for culturing mouse L-cells....Hoagland's No. 2 Basal Salt Mixture from Sigma-Aldrich

During many experiments in molecular biology, the individual mRNA expression pattern of a cell is examined in order to investigate the reaction of a cell to exogenous influences such as viral infections or medical treatment. To allow unstable mRNA to be examined more thoroughly, it is converted to cDNA. If all iso...Structural Analysis of Glycosylated Peptides in Complex Mixtures with Ion Trap MSn

There has been a mixed response from private professional colleges regarding the issue of having a common entrance examination for admission into medical and engineering colleges // . Few educational institutions are under the opinion that the admission should be based on higher secondary marks alone. Following the judgment of the Supreme court that private colleges have the right to d...Mixing Ginseng and Blood Thinners Might Be Dangerous
New research shows mixing warfarin with ginseng, one of the best-selling herbal supplements, could have significant consequences. Researches say // anyone who takes both ginseng and warfarin, also known as Coumadin, should tell his or her doctor. They also urge doctors prescribing the anti-clotting drug to ask their patients if they regularly take ginseng. Specialists say warfarin has a...Increasing Insulin Response In Type 2 Diabetics With New Protein Mixture
Diabetes remains one of the significant health problems to be tackled despite significant medical// advancement. It requires a multi faceted approach. A protein-based diet could help in improving resistance in Type II diabetes. A recent study shows that consuming a protein hydrolysate and amino acid mixture with carbohydrates increases insulin production in type 2 diabetics, and could...DNA Identity Mix-Up In Bone Marrow Donors, And Miscarriages Of Justice Involved
In what may sound as a typical open-and-shut case, a clear DNA match was made between semen from a serious sexual assault// and a blood sample from a known criminal. However, the criminal in question was in jail when the assault took place. Forensic scientists had already matched the crime sample to the DNA profile of another person who was their prime suspect. It was only after careful d...Hookah And The Gums: A Dangerous Mix
An article published in the November issue of the Journal of Periodontology says that smoking a hookah or a water pipe has the same effect on the gums as smoking a cigarette//. Both promote periodontal disease and are equally devastating as far as the oral hygiene is concerned. The article notes that the hookah has become pretty popular in Mediterranean restaurants, cafes and bars. It...Penicillin-Streptomycin Mixture
