Resumen
Background: Autoradiography of tissue with radioactive substance such as Thorotrast by Fuji Computed Radiography (FCR) has been available. We obtained autoradiographs from Thorotrast-deposited tissue by FCR. However, the nature of radiation from tissue with Thorotrast was not certain, because alpha particles are shielded by the plastic front of the FCR cassette. Therefore, we undertook investigation to clearly explain the nature of radiation from Thorotrast in case of autoradiography.Materials and Methods: Tissue blocks of liver and spleen with Thorotrast deposition were imaged by autoradiogra

Resumen
Probes labeled with 33P have potential for widespread use in in situ hybridization because they are better able to detect relatively scarce mRNAs compared with probes labeled with 35S, but the relatively short half-life of 33P is a disadvantage when it is used as a radioactivity standard for quantitative autoradiography. To determine if plastic sections containing 14C can be used as standards for quantitative autoradiography with 33P, we co-exposed 33P-labeled liver paste sections and 14C-plastic standards to Hyperfilm beta max. The autoradiographic response of Hyperfilm beta max to these isot

Resumen
Chronic hypoxia induces a hyperadrenergic state which down-regulates beta-adrenergic receptors (beta-AR) in the heart. We visualized lung beta-AR binding sites after adaptation to chronic hypoxia by autoradiography of whole lung sections labeled with 50 pM 125I-labeled pindolol. A low concentration of agonist (32 nM isoproterenol) selectively masked beta-ARs with high affinity for agonists. Total specific beta-AR binding increased twofold with hypoxia. In both the control and hypoxic lung sections, 60–70% of the beta-ARs were in a high-affinity state, which could be reversed by guanine nucleot

Resumen
PURPOSE: Pathological studies suggest that neuroinflammation is exacerbated by increased beta-amyloid (Aβ) levels in the brain early in Alzheimer's disease (AD). The time course and relationships between astrocytosis and Aβ deposition were examined using multitracer in vivo positron emission tomography (PET) imaging in an AD transgenic mouse model, followed by postmortem autoradiography and immunohistochemistry analysis. METHODS: PET imaging with the amyloid plaque tracer (11)C-AZD2184 and the astroglial tracer (11)C-deuterium-L-deprenyl ((11)C-DED) was carried out in APPswe mice

Resumen
AbstractThe significance of the beta adrenergic system in the nasal mucosa isunclear. The authors have used the technique of autoradiography to localize and classify beta adrenoceptors in human nasal mucosa. The receptors have been found to beexclusively of thebeta-2 subtype and the highest density is found in the glandularducts. It is suggested that the beta-adrenergic system may have a physiologically important role in controlling the electrolyte composition of nasal secretions.

Resumen
We describe two different techniques with plastic embedding in in situ hybridization histochemistry (ISHH). Their applicability was demonstrated by use of human placenta of the tenth gestational week and a tritium-labeled cDNA probe for the beta-subunit of hCG. In the first method, ISHH was performed on whole pieces of tissue (en bloc ISHH) pretreated with a weak acid solution, embedded in methacrylate, and sectioned at 3 microns for autoradiography. In the second technique, en bloc ISHH was carried out on tissue pre-treated with the weak acid and thereafter with detergent to further facilitat

Resumen
This thesis presents three main strands of work concerned with developing digital imaging for high throughput beta autoradiography. These three strands comprise work with the image sensor technology, Monte Carlo simulation and the use of post-acquisition image analysis based on image registration. In this way, the complete autoradiography imaging chain is addressed. CCD and CMOS imaging technologies are presented as potential imaging alternatives to using conventional film in autoradiography. These digital technologies exhibit enhanced sensitivity, dynamic range and linearity compared to film

Les détecteurs gazeux ont démontré, au cours de ces dernières décennies, leur haute performance pour l'imagerie de particules radioactives, atteignant des résolutions spatiales inférieures à 100 µm. Les propriétés scintillantes de certains mélanges gazeux, combinées au gain important des détecteurs gazeux et à l'usage d'une caméra à bas bruit électronique, ont permis d'utiliser la lumière scintillée pour l'imagerie. Cette approche permet d'obtenir une large surface de détection et une haute résolution spatiale tout en réalisant l'imagerie en temps réel à un coût par pixel réduit, avec une faib

Resumen
The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. BMAA can cause long-term neurodegenerative alterations in rats exposed during the neonatal period, a period that corresponds to the last trimester and the first few years of life in humans. As BMAA has been reported to be bioaccumulated in the aquatic food chain and detected in mussels, crayfish and fish used for human consumption, the main aim of this thesis has been to investigate the

Resumen
Radioactive waste management is nowadays, after nearly 50 years of concern, a technical and economical challenge faced by existing nuclear power countries. In decommissioning of nuclear facilities after removal of the nuclear equipment (laboratory materials, glove boxes, etc.), the radioactive inventory of the various building materials is needed to state the working condition for dismantling. Thus, characterization is essential for decommissioning and moreover for radioactive waste classification and management. A radionuclide imaging technique, the Digital Autoradiography (DA), also known as
