A survey of patients with facial angiofibromas associated with tuberous sclerosis complex: Short-, medium- and long-term efficacy and safety of topical rapamycin.

Aims: Topical rapamycin is used to reduce facial angiofibromas in patients with tuberous sclerosis (TSC). In the absence of a commercially available preparation, numerous formulations have been tested clinically, although only in the short term.

Methods: The pharmacy at Angers University Hospital (France) produced a cream formulation that was administered to people presenting this genetic disease.

Characterization of microparticles of iron oxide for magnetic resonance imaging.

Microparticles of iron oxide (MPIOs) are increasingly used for contrast generation in magnetic resonance imaging (MRI). In particular, Dynabeads® MyOne™ Tosylactivated MPIOs have enabled sensitive and targeted molecular imaging, e.g.

Brain irradiation leads to persistent neuroinflammation and long-term neurocognitive dysfunction in a region-specific manner.

Long-term cognitive deficits are observed after treatment of brain tumors or metastases by radiotherapy. Treatment optimization thus requires a better understanding of the effects of radiotherapy on specific brain regions, according to their sensitivity and interconnectivity. In the present study, behavioral tests supported by immunohistology and magnetic resonance imaging provided a consistent picture of the persistent neurocognitive decline and neuroinflammation after the onset of irradiation-induced necrosis in the right primary somatosensory cortex of Fischer rats.
