Cerebellar hemangioblastoma is a rare cause of secondary erythrocytosis. Although the erythrocytosis is a result of erythropoietin (Ep) stimulation, direct evidence of Ep synthesis by the tumor has been lacking. In an erythrocytotic patient with a cerebellar hemangioblastoma we found elevated levels of Ep in the tumor cyst fluid and for the first time demonstrated Ep mRNA in the tumor by Northe...

Kuslmer et r:r.Z [9], [10] have posed the problem of characterising the "EP" ftulction f(S) for which E(f(S)) = A fer), whenever the m x mmatrix S has the Wishart distribution n W(m,n,L). In this article, we obtain integral representations for all non-negative EP ftmctions. It is also shown that any botulded EP ftulction is harmonic, and that EP polynomials may be used to approximate the flmcti...

This paper reports on two discrimination experiments involving Portuguese data. The findings support the prosodic contrast between EP and BP and stress the role played by intonation in this contrast. They also show that the perceptual distance between EP and BP is smaller than that between EP and Dutch. The robust distinction between EP and Dutch provides evidence for different perceptual weigh...

OBJECTIVE Anecdotal reports have suggested mood improvement in patients with bipolar disorder immediately after they underwent an echo-planar magnetic resonance spectroscopic imaging (EP-MRSI) procedure that can be performed within clinical MR system limits. This study evaluated possible mood improvement associated with this procedure. METHOD The mood states of subjects in an ongoing EP-MRSI ...

This study investigated the effects of different planes of nutrition in early pregnancy (EP) and mid-pregnancy (MP) of crossbred ewes on carcass characteristics of male offspring and reproductive performance of female offspring. During EP (d 1 to 39 after synchronized mating) ewes were allocated 60% (low, L-EP), 100% (medium, M-EP), or 200% (high, H-EP) of their energy requirements for maintena...

High and lower affinity receptors for erythropoietin (EP) were initially identified on a very pure population of EP-responsive erythroblasts obtained from the spleens of mice infected with anemia strain of Friend virus (FVA). The structure of the receptor for EP in these cells was determined to be proteins of 100 and 85 Kd by cross-linking 125I-EP. In this investigation, studies on the receptor...

A method for the prediction of Energy Production (EP) in Concentrating Photovoltaic (CPV) installations is examined in this study. It presents a new method that predicts EP by using Global Horizontal Irradiation (GHI) and the Photovoltaic Geographical Information System (PVGIS) database, instead of Direct Normal Irradiation (DNI) data, which are rarely recorded at most locations. EP at four Spa...

The binding of labeled erythropoietin (EP) to cell surface receptors and subsequent processing of the hormone within the cell was studied in erythroid cells procured from the spleens of mice infected with the anemia strain of Friend virus. These immature erythroid cells respond to EP in culture to differentiate into reticulocytes and erythrocytes. Radiolabeled EP (both iodinated and tritiated) ...

PURPOSE To determine the expression and precise cellular and subcellular localization of the EP prostanoid receptor subtypes EP(1) through EP(4) and the FP receptor in normal human ocular tissues on the protein and mRNA levels. METHODS Expression of EP and FP receptor proteins was examined by immunohistochemistry on the light microscopic level, using subtype-specific antibodies on frozen and ...
