Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while electrical stimulation usually requires invasive wires, is limited in its resolution, and is nearly impossible to administer within certain parts...
Living cells inside the body could be placed under surveillance–their location and migration noninvasively tracked in real time over many days–using a new method developed by researchers at KAUST. The technique uses magnetic core-shell iron nanowires as nontoxic contrast agents, which can be implanted into live cells, lighting up those cells’ location inside a living...
New research has found an association between some popular heartburn treatments and iron deficiency. Heartburn is a symptom of gastroesophageal reflux, which is caused by hydrochloric acid rising into the throat. This condition affects more than two million Australians and is often treated with medications that suppress acid secretion. The collaboration between academics at the...
July 17, 2018, Radiological Society of North America A new, highly accurate MRI technique can monitor iron levels in the brains of multiple sclerosis (MS) patients and help identify those at a higher risk for developing a physical disability, according to a study published in the journalRadiology. Image shows voxelwise analysis of quantitative susceptibility maps within...
