OBJECTIVES The purpose of this study was to perform a head-to-head comparison of plaque observations with multislice computed tomography (MSCT) to virtual histology intravascular ultrasound (VH IVUS). BACKGROUND The VH IVUS allows in vivo coronary plaque characterization with high spatial resolution. Noninvasively, plaques may be evaluated with MSCT, but limited data are available. METHODS ...
Cerebral metabolic dysfunction in patients with dementia with Lewy bodies and visual hallucinations.
AIMS To identify the pattern of cerebral hypometabolism in patients with dementia with Lewy bodies (DLB) and visual hallucinations (VH). METHODS Fourteen patients with DLB and VH, 7 with DLB without VH and 16 healthy controls underwent clinical and (18)F-FDG PET evaluations. The 2 patient groups did not significantly differ in their clinical characteristics, except in the occurrence of VH. A ...
In order to understand the generation of antibody diversity in cattle, seven cDNAs, from heterohybridomas secreting bovine IgM and IgG1 antibodies, were cloned and structurally analyzed for rearranged bovine VDJ genes. All of the seven bovine VH genes, together with four available bovine VH gene sequences, shared a high nucleotide sequence homology (84.2-93.5%). Based upon the criteria of nucle...
BACKGROUND Recent studies show that virtual histology intravascular ultrasound (VH-IVUS) can identify plaques at high risk of rupture, such as thin-capped fibroatheromata, raising the possibility of immediate targeted intervention. However, plaque classification entails border recognition and subjective assessment of plaque architecture, introducing inter-observer variability without confirmati...
The vitreous humour (VH) is a complex biofluid that occupies a large portion of the eyeball between the lens and the retina, and exhibits non-Newtonian rheological properties that are key for its function in the eye. It is often possible to distinguish two different phases in VH, known as liquid and gel phases (Sebag J Eye 1: 254–262, 1987). In this work, we present a detailed rheological chara...
AIM We previously reported unexpectedly robust associations between vascular haemodynamic (VH) anomalies in the principal extracranial cerebral veins, causing chronic cerebrospinal venous insufficiency (CCSVI), and multiple sclerosis (MS). Aim of this study was to investigate the relationship between the VH changes and MRI measures of MS disease severity in a cross sectional survey. METHODS T...
We have constructed anti-CD40 immunotoxins consisting of the single chain Fv (sFv) region of the anti-human CD40 mAb G28-5 fused to a truncated form of Pseudomonas exotoxin, PE40. CD40 is an integral membrane glycoprotein found on the surface of B-lineage cells, including lymphomas and leukemias, as well as certain carcinomas. Two forms of the immunotoxin were constructed, one with the light ch...
Five parameters are needed to describe VTI anisotropy in 2-D elastic media. With conventional streamer data and considering that we have a kinematically accurate NMO velocity (vnmo) and η (or horizontal velocity, vh) obtained from tomographic methods, we first show that a parameterization given by vh, η and allows us to focus the inversion to update vh (for traveltime and amplitude fitting) and...
BACKGROUND AND OBJECTIVES The immunoglobulin VH gene mutation status is a strong prognostic indicator in B-cell chronic lymphocytic leukemia (CLL), since unmutated VH genes are correlated with short survival. However, the traditional cut-off level dividing mutated and unmutated cases, i.e. more or less than 2% mutations, has been questioned and other cut-offs have been suggested. We investigate...
