Nanometric crystals of maghemite are known to exhibit superparamagnetism. Because of
the significance of their magnetic moment, maghemite nanoparticles are exceptional …

In the absence of disease, the vasculature of the mammalian eye is quiescent, in part
because of the action of angiogenic inhibitors that prevent vessels from invading the cornea …

Ferritin, the iron storing protein, is known to darken T2‐weighted MRI. This darkening can be
used to non‐invasively measure iron content. However, ferritin's behavior is not the same in …

Post-dural puncture headache (PDPH) is a well recognised complication of spinal and
epidural anaesthesia. It can also occur after diagnostic or therapeutic lumbar puncture. Few …

Evaluating and understanding the performances of magnetic colloids as contrast agents for
MRI requires a theory describing their magnetic interactions with water protons. The field …

Since 1/T2 of protons of tissue water is generally much greater than 1/T1 at typical imaging
fields, small single‐ion contrast agents–such as Gd (DTPA), which make comparable …

Background Healthcare workers have historically experienced symptoms of post-traumatic
stress disorder, depression and anxiety with previous infectious outbreaks. It is unknown if …

Computer simulations of water transverse relaxation induced by superparamagnetic
particles are shown to disagree with the available theories, covering the slow diffusion …

Ferrite superparamagnetic (SPM) nanoparticles in aqueous suspensions shorten the
nuclear magnetic relaxation of water protons. For transverse relaxation, that effect is …

Packed bed unit operations are required for many commercial chemical processes. The
ability to a priori predict void fraction and pressure drop in a packed bed would significantly …
