In a discovery published in the journal Nature, an international team of researchers has described a novel molecular device with exceptional computing prowess. Reminiscent of the plasticity of connections in the human brain, the device can be reconfigured on the fly for different computational tasks by simply changing applied voltages. Furthermore, like nerve cells can […]
A team led by scientists at the UNC School of Medicine identified a molecule called microRNA-29 as a powerful controller of brain maturation in mammals. Deleting microRNA-29 in mice caused problems very similar to those seen in autism, epilepsy, and other neurodevelopmental conditions. The results, published in Cell Reports, illuminate an important process in the […]
Brazilian researchers who study a native venomous fish have confirmed a route to drug development for the treatment of chronic inflammatory diseases such as multiple sclerosis and asthma. The venomous toadfish Thalassophryne nattereri contains a peptide (TnP) with anti-inflammatory and anti-allergic potential. Confirmation of this potential has now come via the zebrafish Danio rerio, a […]
Skip to: What is CVID? What is the prevalence of CVID? What are the causative factors? How CVID is inherited? What are the common symptoms? How is CVID diagnosed? How is CVID treated? Common variable immune deficiency (CVID) is a genetic disorder characterized by a weakened immune system. Patients with CVID frequently suffer from infections. […]
Ancient Indian sages, Egyptians and Greeks, and Romans, have all described sleep in various ways, including naming the gods who brought dreams to sleepers. It was also well known that many people experienced sleep in two shifts, with an hour or three of intervening wakefulness, when one could have quiet time alone or visit one’s […]
Skip to: What is Plasmonics? Applications Enhancing Raman Spectroscopy Signals Plasmonic Nanoscopy and Imaging Plasma is one of the fundamental states of matter that is generated when a neutral gas is heated or subjected to a strong electromagnetic field, both of which can result in the breaking of bonds and the stripping of electrons from […]
Skip to: What is nitric oxide? Treatments for eczema and other skin conditions Using nitric oxide to treat eczema Eczema is a skin condition that causes the skin to become red, cracked, dry, and very irritated. There are many different forms of topical treatment for eczema and its related skin conditions. The anti-inflammatory effects of […]
Researchers from the German Center for Neurodegenerative Diseases (DZNE), UK and Japan have developed a neurologically acting protein and tested it in laboratory studies. In mice, the experimental compound ameliorated symptoms of certain neurological injuries and diseases, while on the microscopic level it was able to establish and repair connections between neurons. This proof-of-principle study […]
In Brazil, scientists affiliated with the Human Genome and Stem Cell Research Center (HUG-CELL) at the University of São Paulo (USP) have identified a molecule capable of reducing the aggressiveness of embryonal central nervous system tumors. These are malignant tumors that start in fetal cells in the brain and mainly affect children up to four […]
Data from the National Institutes of Health (NIH) indicate that approximately 50,000 people receive a diagnosis of Parkinson’s disease each year in the United States. In terms of its worldwide prevalence, studies have shown that Parkinson’s disease affects one percent of the population aged 60 and over, and it is the second most widely diagnosed […]
