In this line, a direct intra-cerebral injection of these anti-DAT aAbs would allow to study the putative direct effects on functional DAT activity and behaviour.
To study the relationship of the caudate DAT concentration with diagnosis independently of the severity of motor disease, we evaluated the caudate DAT concentration using a GLM that included putamen DAT concentration as a covariate in the original pool of predictors.
In another study, DaT scan was shown to have sensitivity for parkinsonism of up to 97% and a specificity for essential tremor up to 100% (Benamer et al., 2000).
Although in the present study DAT is more sensitive than ELISA, the subjective nature and longer waiting time before reading the results might limit widespread and large scale usage of DAT for epidemiological studies [ 61].
Tracer studies (DAT Scan and IBZM Spect) revealed loss of presynaptic dopamine as well as a reduction of the post-synaptic dopaminergic receptor state.
To our knowledge, the present study is the first to assess DAT binding in the partially 6-OHDA-lesioned rat, using small-animal SPECT/CT imaging.
"I 'fraid to go to sleep in dat gondola.
Also, as with many prior studies with DaT scans, our study used clinical follow-up as the diagnostic reference standard, which intrinsically cannot prove greater accuracy than thorough clinical evaluation itself.
(3) Though our data sample is larger than the previous studies on DAT availability in smoking, the study is still underpowered to detect subtle changes in DAT availability related to its variation between subjects and a [123I]FP-CIT SPECT test-retest variability of approximately 10%.
In the present study, the DAT and IBZM SPECTs were done on a hybrid gamma-camera system, an Infinia Hawkeye (General Electric, Milwaukee, WI, USA) at baseline and at sequential timepoints up to 3 years from inclusion.
