Imaging of tau deposits in adults with Niemann-Pick type C disease: a case-control study
Abstract Purpose Niemann-Pick type C (NPC) is a cholesterol storage disease characterized by disruption in the endosomal–lysosomal transport system that leads to the accumulation of cholesterol and glycolipids in lysosomes. Developmental cognitive delay and progressive motor and cognitive impairment are characteristic of the disease. Tau accumulation has been reported in some NPC patients. We investigated the presence of tau and...

Confirmation of the prognostic value of pretherapeutic tumor SUR and MTV in patients with esophageal squamous cell carcinoma
Abstract Purpose The prognosis for patients with inoperable esophageal carcinoma is still poor and the reliability of individual therapy outcome prediction based on clinical parameters is not convincing. In a recent publication, we were able to show that PET can provide independent prognostic information in such a patient group and that the tumor-to-blood standard uptake ratio (SUR) can improve the prognostic value of tracer uptake values....

Motion in Magnetic Resonance: New Paradigms for Improved Clinical Diagnosis
Recent innovations in magnetic resonance, involving both hardware and software, that effectively deal with motion—whether inadvertent on the part of the patient or due to respiration and cardiac contraction—are reviewed, emphasizing major current advances. New technology involving motion sensing (kinetic, respiratory, and beat) is enabling simpler, faster, and more robust monitoring of the sources of motion. This information is being integrated, with new innovative imaging approaches, to effectively...

The Role of Monocytes and Macrophages in Human Atherosclerosis, Plaque Neoangiogenesis, and Atherothrombosis
Atherosclerosis is one of the leading causes of death and disability worldwide. It is a complex disease characterized by lipid accumulation within the arterial wall, inflammation, local neoangiogenesis, and apoptosis. Innate immune effectors, in particular monocytes and macrophages, play a pivotal role in atherosclerosis initiation and progression. Although most of available evidence on the role of monocytes and macrophages in atherosclerosis is derived from animal studies, a growing body of evidence...

Auditory white matter pathways are associated with effective connectivity of auditory prediction errors within a fronto-temporal network
Publication date: Available online 5 April 2019Source: NeuroImageAuthor(s): Lena K.L. Oestreich, Roshini Randeniya, Marta I. GarridoAbstractAuditory prediction errors, i.e. the mismatch between predicted forthcoming auditory sensation and actual input, trigger detection of surprising auditory events in the environment. Auditory mismatches engage a hierarchical functional network of cortical sources, which are also interconnected by auditory white matter pathways. Hence it is plausible that these...

Publication date: Available online 4 April 2019Source: NeuroImageAuthor(s): Zachary A. Yaple, W. Dale Stevens, Marie ArsalidouAbstractWorking memory, a fundamental cognitive function that is highly dependent on the integrity of the prefrontal cortex, is known to show age-related declines across the typical healthy adult lifespan. Moreover, we know from work in neurophysiology that the prefrontal cortex is disproportionately susceptibly to the pathological effects of aging. The n-back task is arguably...
