imaging of scar tissue formation




organs respond to injuries with the formation of new fibrous tissue, which can result in scarring. this process called fibrogenesis can now be monitored noninvasively on a molecular level, as american scientists report in the journal angewandte chemie. they have created a new gadolinium-based probe ...



study: intracranial pathology not necessary for gadolinium deposition in brain t




oak brook, ill. - minute traces of gadolinium, the contrast agent used to enhance mr images, are often retained in the brain tissue of patients years after undergoing mri. some studies have suggested this deposition was limited to patients with underlying brain pathology, such as a tumor or infectio...

making ferromagnets stronger by adding non-magnetic elements




researchers at the u.s. department of energy's ames laboratory discovered that they could functionalize magnetic materials through a thoroughly unlikely method, by adding amounts of the virtually non-magnetic element scandium to a gadolinium-germanium alloy.

mri contrast agents accumulate in the brain




the international society for magnetic resonance in medicine (ismrm) has provided new guidance in the use of contrast agents during mri scans. emerging research suggests gadolinium-based contrast agents, injected in a patient's veins to brighten tissues in mri images, accumulate in the brain. more t...



block copolymer micellization as a protection strategy for dna origami




the precise positioning of individual molecules with respect to one another is fundamentally challenging. dna nanotechnology enables the synthesis of nanometer-sized objects with programmable shapes out of many chemically produced dna fragments. one of the most widely used methods in this field is c...

hydrogen bonds directly detected for the first time




a hydrogen bond forms between a propellane (lower molecule) and the carbon monoxide functionalized tip of an atomic force microscope. the measured forces and the distance between the oxygen atom at the afm tip and the propellane's hydrogen atoms correspond precisely to the calculations. credit: univ...

metal-free mri contrast agent could be safer for some patients




cambridge, ma -- to enhance the visibility of organs as they are scanned with magnetic resonance imaging (mri), patients are usually injected with a compound known as a contrast agent before going into the scanner. the most commonly used mri contrast agents are based on the metal gadolinium; however...
