Autor: Jorgen Thorup, Kolja Kvist, P. E. Høyer, C. Yding Andersen, Kjeld Møllgård, A.G. Byskov

Publikováno v: Human Reproduction. 21:484-491

BACKGROUND: Boys with cryptorchidism often face fertility problems in adult life despite having orchiopexy performed at a very young age. During this operation, a biopsy of the testis is normally taken in order to evaluate their infertility potential

Stem cell factor and c-Kit in human primordial germ cells and fetal ovaries

Autor: Kjeld Møllgård, P. E. Høyer, Anne Grete Byskov

Publikováno v: Molecular and Cellular Endocrinology. 234:1-10

The distribution of the tyrosine kinase receptor c-Kit and its ligand stem cell factor (SCF) was evaluated by immunohistochemistry in primordial germ cells (PGCs) and human embryonic gonads during weeks 5-8 of prenatal life, and fetal ovaries during

Glucose and pyruvate metabolism during mouse gonadal sex differentiation

Autor: Lars Kayser, Tiny Roed, P. E. Høyer, Anne Grete Byskov

Publikováno v: Journal of Experimental Zoology. 289:130-138

In the mouse, gonadal sex differentiation starts around E12 and meiosis begins in the ovary shortly after E13. In the search for metabolic changes that might be correlated to gonadal sex differentiation and/or possibly the onset of meiosis, we invest

Publikováno v: Histochemical Journal. 31:485-493

Pseudomonas aeruginosa agglutinin (PA-IL) staining and the influence of various carbohydrates on lectin binding to muscle sections were investigated quantitatively using a scanning and integrating microspectrophotometre. A strong dose-dependent inhib

The impact of fixatives on the binding of lectins to N-acetyl-glucosamine residues of human syncytiotrophoblast: a quantitative histochemical study

Autor: Svend Kirkeby, P. E. Høyer

Publikováno v: Journal of Histochemistry & Cytochemistry. 44:855-863

We describe a quantitative histochemical method for demonstration of five N-acetyl-glucosamine binding lectins in the syncytiotrophoblast of human term placenta. The method employs biotinylated lectins and alkaline phosphatase-conjugated avidin. The

Microfluorometric kinetic analysis of cathepsin B activity in single human thyroid follicular epithelial cells using image analysis and continuous monitoring

Autor: J. Thomsen, Lars Kayser, P. E. Høyer, Hans Perrild

Publikováno v: The Histochemical Journal. 28:257-263

The activity of a cysteine proteinase, cathepsin B (EC 3.4.22.1), was determined in unfixed single human thyroid follicular epithelial cells at room temperature using an image analysis system. The formation of the reaction product was monitored every

Immunocytochemical Localisation of Tumor Necrosis Factor α in Thyroid Tissues from Patients with Neoplastic or Autoimmune Thyroid Disorders

Autor: B E Olsen, Lars Kayser, H Broholm, D Francis, Klaus Bendtzen, Hans Perrild, P E Høyer

Publikováno v: Autoimmunity. 23:91-97

It is disputed to what extent tumor necrosis factor-alpha is present in the thyroid follicular epithelial cells and/or in the interstitial cells in different disorders of the thyroid gland. We describe the immunohistochemical detection of tumor necro

Simultaneous quantification of DNA and RNA in tissue sections. A comparative analysis of the Methyl Green-Pyronin technique with the Gallocyanin chromalum and Feulgen procedures using image cytometry

Autor: P. E. Høyer, E. K. W. Schulte, Hans Lyon

Publikováno v: The Histochemical Journal. 24:305-310

For simultaneous cytophotometric measurement of DNA and RNA, the standardized Methyl Green-Pyronin Y technique is an obvious choice. It is, however, first necessary to correlate the uptake of Pyronin Y to the staining intensity of RNA. The material c

Quantitative cytochemical demonstration of intracellular thyroglobulin in cultured human thyrocytes. Effects of fixatives, TSH and Interleukin-1?

Autor: P. E. Høyer, Lars Kayser, Birgitte Engelbrecht Olsen

Publikováno v: The Histochemical Journal. 23:235-240

A quantitative immunocytochemical method is described for measuring intracellular thyroglobulin in human thyrocytes grown in monolayer, based on the imidazole-enhanced 3,3'-diaminobenzidine/peroxidase reaction. The influence of ten different fixative
