Partial volume and mixed tissue sampling errors can cause significant inaccuracy in
quantitative positron emission tomographic (PET) measurements. We previously described a …

The accurate quantification of brain radioactivity concentration is limited by the spatial resolution
of the PET scanner for structures smaller than 2–3 times the resolution. In the presence …

Background Partial volume effects (PVEs) in PET imaging result in incorrect regional activity
estimates due to both spill-out and spill-in from activity in neighboring regions. It is important …

Purpose Our goal was to evaluate the influence of spatially heterogeneous background
activity on “hot object” quantitation in brain emission CT. Method We studied the effects of …

Selective mutism is a pediatric psychiatric disorder that occurs when a child consistently fails
to speak in specific situations in which speaking is expected, such as at school and social …

DNA polymerase γ (pol γ), encoded by POLG, is responsible for replicating human mitochondrial
DNA. About 150 mutations in the human POLG have been identified in patients with …

Background Dialysis and kidney transplant patients are vulnerable populations for COVID-19
related disease and mortality. Methods We conducted a prospective study exploring the …

This memo to the President describes a future grounded in the present in which criminal law
is poised to swallow immigration law. Immigration law today is clothed with so many …

Background Vulnerable dialysis and kidney transplant patients show impaired seroconversion
rates compared to medical personnel eight weeks after SARS-CoV-2mRNA vaccination. …
