Dynamic Brain Cells Crucial to CNS
May 10, 2013 11:41 am | News | CommentsBy monitoring the behavior of a class of cells in the brains of living mice, neuroscientists discovered that these cells remain highly dynamic in the adult brain, where they transform into cells that insulate nerve fibers and help form scars that aid in tissue repair.
Three-port Hypoxystation
May 10, 2013 11:40 am | Product Releases | CommentsDon Whitley Scientific Limited has launched a new addition to its range of Hypoxystation cell culture workstations—the Whitley H45 Hypoxystation. The H45 has 50% more capacity than the H35 Hypoxystation but maintains the ability to create hypoxic and anoxic conditions within a controlled and sustained workstation environment.
Colonized Bacteria Follow Economic Strategy
May 10, 2013 11:14 am | News | CommentsBacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to many economies, according to a new study. This is the first study identify the strategy by which bacteria form the micro-colonies that become biofilms, which can cause lethal infections.
Protein Reverses Age-related Heart Failure
May 10, 2013 10:53 am | News | CommentsResearchers have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for the form of age-related heart failure that affects millions of Americans. When the protein was injected into old mice, the hearts were reduced in size and thickness, resembling the healthy hearts of younger mice.
Study Reveals How Nerve Axons Self-destruct
May 10, 2013 10:29 am | News | CommentsMany medical issues affect nerves, from injuries in car accidents and side effects of chemotherapy to glaucoma and multiple sclerosis. The common theme in these scenarios is destruction of nerve axons, the long wires that transmit signals to other parts of the body, allowing movement, sight and sense of touch, among other vital functions.
Stem Cell Epigenomics Mimic Early Human Development
May 10, 2013 9:59 am | News | CommentsScientists have long known that control mechanisms known collectively as "epigenetics" play a critical role in human development, but they did not know precisely how alterations in this extra layer of biochemical instructions in DNA contribute to development.
3 suspected cases of SARS-related virus in France
May 10, 2013 5:15 am | by GREG KELLER - Associated Press - Associated Press | News | CommentsFrench health officials said Friday they are investigating three suspected cases of a deadly new respiratory virus related to SARS, while a man confirmed to have the virus remains hospitalized. Beatrice Degrugillers, a spokeswoman for the regional health agency in France's Nord-Pas-de-Calais...
Quantitative RNA-seq Kit
May 9, 2013 2:23 pm | Product Releases | CommentsBioo Scientific’s NEXTflex qRNA-seq Kit is a library preparation technology enabling high precision gene expression analysis. Molecular indices are ligated to cDNA fragment ends upstream of PCR amplification.
Successful DNA Sequencing with Ever Smaller Samples
May 9, 2013 1:45 pm | by Cynthia Fox | Articles | CommentsDNA sequencing is busting Moore’s Law by getting far cheaper, far faster than expected. But it is also getting far more sensitive. Researchers can sequence DNA samples 25 times smaller than they could a year ago. For whole genome sequencing, in recent months, one group has routinely gone from sequencing as little as one microgram of input to 100 nanograms.
Man wrongly told he had terminal cancer gets $60K
May 9, 2013 1:04 pm | by The Associated Press | News | CommentsA judge has ordered the Fort Harrison VA Medical Center to pay nearly $60,000 to a Winston man who was wrongly diagnosed with brain cancer and told he had just a few months to live. U.S. District Judge Donald Molloy wrote that the distress Mark Templin and his family suffered was caused by Dr....
Biological Safety Cabinets with SmartFlow Technology
May 9, 2013 11:54 am | Product Releases | CommentsThermo Scientific 1300 Series A2, Class II, Type A2 biological safety cabinets provide reliability, ergonomics and energy efficiency for demanding laboratory applications.
Imaging Technology Predicts Long-term Brain Damage
May 9, 2013 11:47 am | News | CommentsA new application of an existing medical imaging technology could help predict long-term damage in patients with traumatic brain injury, according to a recent study. The authors analyzed brain scans using applied rapid automated resting state magnetoencephalography (MEG) imaging, a technique used to map brain activity by recording magnetic fields produced by natural electrical currents in the brain.
Diabetes Cured in Mice
May 9, 2013 11:03 am | News | CommentsResearchers have made a significant first step with newly engineered biomaterials for cell transplantation that could help lead to a possible cure for Type 1 diabetes, which affects about 3 million Americans. Engineers and clinicians have successfully engrafted insulin-producing cells into a diabetic mouse model, reversing diabetic symptoms in the animal in as little as 10 days.
Epigenetic Factor Can Control Carcinoma Spread
May 9, 2013 10:31 am | News | CommentsVery little has been known about the epigenetic events that occur prior to the invasive growth of head and neck squamous cell carcinomas and their spread to other parts of the body, or metastasis. Researchers discovered what could be a crucial step toward understanding the process that activates the cancer cells.
Drugmakers, health groups bring poor girls vaccine
May 9, 2013 7:34 am | by LINDA A. JOHNSON - AP Business Writer - Associated Press | News | CommentsTwo multinational drugmakers are teaming up with top global health groups to protect millions of girls in the world's poorest countries from deadly cervical cancer. Starting with pilot programs in eight Asian and African nations, the ambitious project ultimately is intended to inoculate more than...
