In fluorescence mode, the use of DPDW can be used to image fluorophore concentration and lifetime in three dimensions.
Since singlet oxygen, the main cytotoxic species produced by PDT, is not able to diffuse over distances longer than 10 20 nm during its excited state lifetime and cell dimensions are approximately 20 μm, the primary sites of photodynamic action should be strictly related to the specific intracellular sensitiser distribution (Moan and Berg, 1991).
Allowing for this finite lifetime adds another dimension to the interest.
Lifetime assessed psychosis dimension scores indicated higher positive symptom scores in patients from "at risk for psychiatric disorder" families compared to patients from "healthy" families (Wald(1) = 6.6293, p = 0.010).
Five dimensions of lifetime parental psychopathology were assessed (depressive disorders, anxiety disorders, substance dependence, antisocial behavior, and psychosis), using the TRAILS Family History Interview (FHI), which was administered at the parent interview [ 26].
This result represents a first step in understanding the factors that affect second dimension column lifetime, and will significantly improve the usability of the LCxLC technique in general.
There appear to be no published reports of systematic studies of the relationship between second dimension column lifetime and any of these variables.
She spent a lifetime inventing characters, in two and three dimensions, and manipulating them within the space of her art's stage.
Two possibilities for ortho-positronium annihilation in the semicrystalline polymer were proposed and analyzed: (a) ortho-positronium annihilates in the crystal phase with a lifetime characteristic of the nanochannel dimensions; (b) ortho-positronium rapidly diffuses into the amorphous phase and annihilates with a lifetime typical of that phase.
Maziade et al have examined lifetime ratings of psychotic symptom dimensions in patients with schizophrenia and Bipolar Disorder [ 20].
