U.S. scientists say they have discovered social interactions can alter the brain's genetic expression far more significantly than has been thought. University of Illinois researchers said our DNA determines a lot about who we are and how we play with others. "But recent studies of social animals -- birds and bees, among others -- show the interaction between genes and behavior is more of a two-way street than most of us realize," the researchers said. Professors Gene Robinson and David...
Xenomics, Inc. (XNOM.PK), a developer of non-invasive next-generation molecular diagnostics, announced today that it has licensed to Sequenom, Inc., a genetics and molecular diagnostics company (NASDAQ: SQNM), exclusive rights to Xenomics patents for the development of prenatal research and diagnostic products based on the Company's proprietary Transrenal DNA/RNA (Tr-DNA/RNA) technology. The agreement provides for an upfront payment, equity participation and royalties on sales of licensed...
CARLSBAD, Calif., Oct. 8 /PRNewswire/ -- GenVault Corporation, the leader in dry, room temperature biosample management, announces the launch of an innovative new product, GenTegra(TM) DNA. GenTegra DNA is a proprietary inorganic matrix with built-in oxidative protection and antimicrobial activity for dry, room temperature transport and storage of purified DNA. GenTegra DNA is provided in ready to use aliquots, and purified DNA dried within GenTegra DNA is simply and fully resolubilized...
The expanding power of DNA analysis is a key focus of this year's 19th International Symposium on Human Identification hosted by Promega Corporation. This year, keynote speaker, Dr. Sean Carroll will discuss the utility of DNA as the "Ultimate Record of Evolution." Additional presentations will feature methods used to identify the slain children of Czar Nicholas who were murdered during the Bolshevik Revolution and advanced technologies used to identify a murderer in a serial murder case in...
BioServe today announced a more affordable pricing plan for its vast bank of DNA with comprehensive, de-identified, covariate data that includes age, gender, diet, body mass index (BMI), and race. In addition, each sample has data on the complete diagnostic and treatment history of the donor. BioServe's DNA represents a wide range of disease states including cancers (breast, prostate, lung, colon, others), diabetes, heart disease, hypertension, arthritis, obesity, as well as some rarer...
By J, Pieter Stevens, Mark J ABSTRACT We perform atomistic simulations on a single collagen molecule to determine its intrinsic molecular strength. A tensile pull simulation to determine the tensile strength and Young's modulus is performed, and a simulation that separates two of the three helices of collagen examines the internal strength of the molecule. The magnitude of the calculated tensile forces is consistent with the strong forces of bond stretching and angle bending that are...
By Knee, Kelly M Dixit, Surjit B; Aitken, Colin Echeverria; Ponomarev, Sergei; Beveridge, D L; Mukerji, Ishita ABSTRACT The A-to-B form transition has been examined in three DNA duplexes, d(CGCGAATTCGCG)^sub 2^, d(CGCGAATTGCGC), and d(CGCAAATTTCGC), using circular dichroism spectroscopy, ultraviolet resonance Raman (UVRR) spectroscopy, and molecular dynamics (MD) simulation. Circular dichroism spectra confirm that these molecules adopt the A form under conditions of reduced water activity....
By Anonymous According to the National Coil Coating Association (NCCA; Cleveland), use of prepainted (coil coated) steel by appliance manufacturers is on the rise. The association says Whirlpool, Trane, General Electric and other appliance OEMs are trading postpainting operations for prepainted metal. NCCA cites the ability of coil- coated steel to meet fingerprint resistance, non-skid and anti- microbial specifications without the need for paint shop environmental controls as reasons for...
By Luntz, Stephen The capacity to track gene expression has been one of the biotechnology revolution's driving forces, so a technology that gives researchers more accuracy and sensitivity has the potential to lead to even more rapid progress. Dr Krassen Dimitrov of the Australasian Institute of Bioengineering and Nanotechnology at the University of Queensland has created what he calls "nanostrings". These are fluorescent pieces of nucleic acid that act like barcodes, binding to RNA molecules...
Stanford University has received two million-dollar grants from the W.M. Keck Foundation for projects aimed at using light to control a variety of cells and exploring how specific enzymes help embryonic stem cells turn into adult cells. The beneficiaries of the grants are Karl Deisseroth, MD, PhD, assistant professor of bioengineering and of psychiatry and behavioral sciences, and Joanna Wysocka, PhD, assistant professor of chemical and systems biology and of developmental biology....
