Proprotein convertase expression and localization in epidermis: evidence for multiple roles and substrates
(Munksgaard International PublishersBlackwell Publishing Ltd, 2001-06)
Specific proteolysis plays an important role in the terminal differentiation of keratinocytes in the epidermis and several types of proteases have been implicated in this process. The proprotein convertases (PCs) are a ...
Signal-to-noise measures for magnetic resonance imagers
(Elsevier, 1993)
The signal-to-noise ratio (SNR) in magnetic resonance imaging represents one of the system operating variables that must be determined both for evaluating the performance of different imaging protocols on a particular ...
The use of ultrasound during spinal cord surgery
(Springer-Verlag; Société Internationale de Chirurgie, 1987-10)
Intraoperative spinal ultrasonography is now considered an indispensable tool in many operations on the spine and spinal cord. Using ultrasonography, surgeons can now easily find and evaluate lesions within the spinal cord, ...
A sequential double-label autoradiographic method that quantifies altered rates of regional glucose metabolism
(Elsevier, 1985-12-30)
An autoradiographic sequential double-label variant of the deoxyglucose method for measurement of local glucose utilization has been developed. This technique takes advantage of the short half-life of the positron emitter, ...
Circumference measurements in obstetrical ultrasound: Ellipse vs. arithmetic mean
(Wiley Subscription Services, Inc., A Wiley Company, 1988-06)
No Abstract.
Quantitative assessment of surface roughness using backscattered ultrasound: The effects of finite surface curvature
(Elsevier, 1994)
We have previously described a technique to quantify surface fibrillatory changes in osteoarthritic articular cartilage. In that study, the angular distribution of the scattered acoustic field from an insonifying source ...
Fast, pseudo-continuous arterial spin labeling for functional imaging using a two-coil system
(Wiley Subscription Services, Inc., A Wiley Company, 2004-03)
A fast, two-coil, pseudo-continuous labeling scheme is presented. This new scheme permits the collection of a multislice subtraction pair in <3 s, depending on the subject's arterial transit times. The method consists of ...
Follow-up imaging of benign pediatric liver tumors
(Springer-Verlag, 1989-05)
Though surgery has been recommended in the past for the management of benign hepatic tumors, the current emphasis is on medical management. This report of 4 cases with long-term (8–28 months) follow-up emphasizes the natural ...
In vivo measures of dopaminergic radioligands in the rat brain: Equilibrium infusion studies
(John Wiley & Sons, Inc., 2002-03-01)
The application of an equilibrium infusion method for measuring specific in vivo radioligand binding in the conscious rat brain was evaluated for two ligands of the dopaminergic system, (+)-Α-[ 11 C]dihydrotetrabenazine ...
MR Imaging of Levator Ani Muscle Recovery Following Vaginal Delivery
(Springer-Verlag London Limited, 1999-08)
Our aim was to quantify the changes that occur in the levator ani muscles (LA) after vaginal delivery using magnetic resonance imaging. Fourteen women underwent MRI 1 day postpartum. Six of them were also scanned 1, 2, 6 ...
