Evaluation of ( - )[18F]fluoroethoxybenzovesamicol as a new PET tracer of cholinergic neurons of the heart
(Elsevier, 1994-02)
18F-labeled ( - )fluoroethoxybenzovesamicol [( - )FEOBV] is a novel PET tracer which binds to the vesicular acetylcholine transporter of cholinergic neurons. To evaluate the in vivo binding specificity and kinetic properties ...
Living ring opening metathesis polymerization of mesogenic norbornene derivatives
(Wiley Periodicals, Inc.Hüthig & Wepf Verlag, 1994-01)
A new class of SCLCPs was prepared by polymerizing mesogenic norbornene derivatives using Mo(CHCMe 2 R)(N‐2,6‐C 6 H 3 ‐ i ‐Pr 2 )(O‐ t ‐Bu) 2 (R = CH 3 or Ph). Monomers based on norbornene ring systems were chosen because ...
Adapting Homogeneous Enzyme-Linked Competitive Binding Assays to Microtiter Plates
(Elsevier, 1994-04)
Recently devised homogeneous enzyme-linked binding assays useful for the rapid detection of carbohydrate structure/content of intact glycoproteins (via use of lectins as binders) and for quantitating given vitamins (e.g., ...
Characterization of [11C]tetrabenazine as an in vivo radioligand for the vesicular monoamine transporter
(Elsevier, 1994-02)
[11C]Tetrabenazine ([11C]TBZ) is a new in vivo radioligand for positron emission tomographic (PET) imaging of vesicular monoamine transporters. The in vivo distribution, metabolism and pharmacological specificity of [11C]TBZ ...
Transforming growth factor-[beta]1 regulates steady-state PTH/PTHrP receptor mRNA levels and PTHrP binding in ROS 17/2.8 osteosarcoma cells
(Elsevier, 1994-05)
The effect of transforming growth factor [beta]1 (TGF-[beta]1) on the expression of mRNA for the parathyroid hormone receptor and binding of iodinated parathyroid hormone-related protein in ROS 17/2.8 osteosarcoma cells ...
Leucite content of selected dental porcelains
(John Wiley & Sons, Inc., 1994-05)
Leucite is a major crystalline component of dental porcelains. The presence of tetragonal leucite in dental porcelains increases their coefficients of thermal expansion due to its high coefficient of thermal expansion ...
Positive and negative regulation of IL-2 gene expression: Role of multiple regulatory sites
(Elsevier, 1994-05)
Interleukin 2 (IL-2) is an important lymphokine required in the process of T cell activation, proliferation, clonal expansion and differentiation. The IL-2 gene displays both T cell specific and inducible expression: it ...
Chromosomal Localization of Four Human VH1-like Protein-Tyrosine Phosphatases
(Elsevier, 1994-07-15)
Four human protein-tyrosine phosphatase (PTPase) genes of the VH1-like subclass were cloned by low-stringency screening of a genomic library. These genes were localized to their respective chromosomes by G-banding and ...
Abnormalities of autonomic nervous control in human hypertension
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-03)
The pathophysiology of various stages of hypertension is different. In early hyperkinetic borderline hypertension, the sympathetic drive to the heart and blood vessels is increased while the parasympathetic cardiac inhibition ...
