A medical group of epilepsy experts on Monday called on the federal government to reconsider classifying marijuana as a dangerous drug so its impact on seizures can be studied. The American Epilepsy Society's statement comes as a British pharmaceutical company is scheduled to begin tests of an...
BD Biosciences, a segment of BD (Becton, Dickinson and Company), offers the BD LSRFortessa X-20 Cell Analyzer. The analyzer delivers high-performance multicolor analysis with a compact footprint measuring 30" x 29" (76.2 X 73.7 cm) and a height of 30" (76.2 cm).
A team of researchers developed a material that could help prevent blood clots associated with catheters, heart valves, vascular grafts and other implanted biomedical devices. Blood clots at or near implanted devices are thought to occur when the flow of nitric oxide, a naturally occurring clot-preventing agent generated in the blood vessels, is cut off. When this occurs, the devices can fail.
The experiences that we accumulate throughout life build expectations that are associated with different scents. These expectations are known to influence how the brain uses and stores sensory information. But researchers have long wondered how the process works in reverse: how do our memories shape the way sensory information is collected?
The bark of the Amur cork tree (Phellodendron amurense) has traveled a centuries-long road with the healing arts. Now it is being put through its paces by science in the fight against pancreatic cancer, with the potential to make inroads against several more.
Since its introduction to the U.S. in 1999, West Nile virus has spread rapidly across North America, threatening wildlife populations and posing a serious health risk to humans. In 2012, there were more than 5,500 human cases of the disease reported in 48 states, the highest number in more than a decade. Now, a team of researchers has created a model to help predict where the disease may occur under future climate change.
Although scientists have decoded the human genome, they still have great difficulty determining the specific genes that are activated to make a kidney cell as opposed to a liver or heart cell. In theory, an easy way to link genes to cells would be to isolate a cell and test it. However, solid human tissue is so closely packed that even the finest surgical techniques cannot separate types of cells efficiently enough for analysis.
Some children who outgrow one type of food allergy may then develop another type of allergy, more severe and more persistent, to the same food. A new study by pediatric allergy experts suggests that healthcare providers and caregivers carefully monitor children with food allergies to recognize early signs of eosinophilic esophagitis (EoE), a severe and often painful type of allergy that has been increasing in recent years.
A team of researchers identified mutations in a gene that can reduce the risk of developing type 2 diabetes, even in people who have risk factors such as obesity and old age. The results focus the search for developing novel therapeutic strategies for type 2 diabetes; if a drug can be developed that mimics the protective effect of these mutations, it could open up new ways of preventing this devastating disease.
In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. The new findings point the way toward a potentially more effective vaccine that would generate V1V2-directed HIV neutralizing antibodies.
A Swedish doctor says four Swedish women who received transplanted wombs have had embryos transferred into them in an attempt to get pregnant. Since 2012, nine women have received wombs donated by relatives in an experimental procedure designed to test whether it's possible to transfer a uterus...
The Olympus FluoView FVMPE-RS, a dedicated multiphoton microscope system, enables high-precision, ultra-fast scanning and stimulation, allowing researchers to see deep within specimens, take measurements at the highest speeds and capture images.
A protein that controls the metamorphosis of the common fruit fly could someday play a role in reversing brain injuries. This protein directs both the early development and regrowth of the tiny branches that relay information from neuron to neuron. Known as dendrites, these thin structures that resemble tree branches are responsible for receiving electrical impulses that flash throughout the body.
Scientist have carried out the first studies of living biological cells using high-energy X-rays. The new method shows clear differences in the internal cellular structure between living and dead, chemically fixed cells that are often analyzed.
Google Glass could potentially save lives, especially in isolated or far-flung locations, say scientists. They are reporting development of a Google Glass app that takes a picture of a diagnostic test strip and sends the data to computers, which then rapidly beam back a diagnostic report to the user.
