Champion of regeneration, the freshwater polyp Hydra is capable of reforming a complete individual from any fragment of its body. It is even able to remain alive when all its neurons have disappeared. Researchers have discovered how: cells of the epithelial type modify their genetic program by overexpressing a series of genes, among which some are involved in diverse nervous functions.
Researchers from the University of Bristol have gained a new insight into how the circadian...
When a high-fat diet causes us to become obese, it also appears to prompt normally bustling...
Using the substance bumetanide in newborn mice, scientists succeeded in attenuating the disease...
Exercise increases levels of a brain-protecting enzyme in mice, according to a new study from Johns Hopkins University. This finding could have implications for people with a variety of neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's, and epilepsy.
As humans have begun to live longer it has become clear that the quality of our lives is equally as important as the duration.
A new study found that gastrointestinal bypass surgery, which is used to treat morbid obesity and diabetes, reduced sugar-seeking behavior in mice by reducing the release of a reward chemical called dopamine in the brain. The findings suggest that positive outcomes are more likely if sugary foods seem less rewarding after surgery.
Cancer researchers at the University of Cincinnati have found a new target that could lead to therapies for a rare type of tumor.
The simple act of running may be sufficient to prevent long-term cognitive impairments caused by prenatal exposure to antiepileptic drugs, according to a study published November 19th in Stem Cell Reports.
During embryonic development, billions of neurons nimbly reposition themselves within the brain and spinal cord, and connect branches to form the neural circuits that ultimately control our movements, perception, and memory. Scientists have long sought to understand the driving forces in this meticulously choreographed dance.
Use Terra’s new control systems to automatically control fan/filter units in modular cleanrooms to achieve desired air change rates and room pressure. Multiple Tier levels with increasing feature availability and sophistication are available to match your cleanroom size, floor-plan complexity and budget.
Using technology invented at MIT, doctors may one day be able to monitor patients’ vital signs by having them swallow an ingestible electronic device that measures heart rate and breathing rate from within the gastrointestinal tract.
Diabetes is often the result of obesity and poor diet choices, but for some older adults the disease might simply be a consequence of aging. New research has discovered that diabetes—or insulin resistance—in aged, lean mice has a different cellular cause than the diabetes that results from weight gain (type 2).
Northwestern Medicine scientists and international colleagues have identified a novel strategy for reducing the side effects of uncontrolled movement caused by the drug levodopa, commonly used to treat the stiffness, tremors and poor muscle control of Parkinson’s disease.
Most people probably think that we perceive the five basic tastes—sweet, sour, salty, bitter and umami (savory)—with our tongue, which then sends signals to our brain “telling” us what we’ve tasted. However, scientists have turned this idea on its head, demonstrating in mice the ability to change the way something tastes by manipulating groups of cells in the brain.
A new inter-disciplinary study led by researchers at Tufts University found that coconut oil effectively controlled the overgrowth of a fungal pathogen called Candida albicans in mice. In humans, high levels of C. albicans in the gastrointestinal tract can lead to bloodstream infections, including invasive candidiasis.
When a piece of machinery breaks down inside an animal facility, we tend to just unplug it and put a piece of tape across or a handmade sign. But then someone who needs the equipment will rip off the tape and try and use it. It is very important that we make sure the machinery is safe from anyone using it until it is repaired. OSHA has a Lockout and Tagout Standard that has to be followed even by animal facilities.
One thing no one in the field can get away from is dealing with biohazardous waste in the vivarium and all the confusion it entails. It affects everyone involved in lab animal care: husbandry, vet services, investigators, staff, and others. So how do we keep everyone safe and sane at the same time?
The MicroFlow II is a Class 1 ductless carbon filtered workstation equipped with Activated Carbon filtration, for fumes, odors, and non-hazardous chemical vapors. Completely self contained with integral recessed work surface to contain spills. A clear hood surrounds the work area and includes a hinged viewing sash for user protection.
