An Autoradiogram of Skeletal Muscle from a Pig Raised on a Farm within 20 km of the Fukushima Daiichi Nuclear Power Plant OAK
YAMAGUCHI, Toshiro; SAWANO, Kaita; FURUHAMA, Kazuhisa; MORI, Chizuo; YAMADA, Kazutaka; 山田, 一孝.
We utilized autoradiography to visualize radioactive contamination in the skeletal muscles of a pig raised within 20 km of the Fukushima Daiichi nuclear power plant following the nuclear accident. The autoradiogram of control muscle showed relatively homogenous exposure. In contrast, the autoradiogram of affected muscle showed a heterogeneous and sporadically dense imaging pattern. Photo luminescence densities of the affected and control muscles were 3.89 ± 0.67 and 2.13 ± 0.43 PSL/mm2, respectively. This difference indicated that radioactive cesium was distributed in the skeletal muscle of the affected pig.

Autoradiography as a tool in primary production research OMA
Mommaerts, J.-P..
Autoradiography of C-14 labelled phytoplankton collected onto a millipore filter allows the determination of the number of photosynthetically active cells in a water sample and thus gives useful information on the standing crop in primary production studies.

Complementarity of radioautographic and immunohistochemical techniques for localizing neuroreceptors at the light and electron microscopy level BJMBR
Beaudet,A..
To assess relationships between neuropeptide-binding sites and receptor proteins in rat brain, the distribution of radioautographically labeled somatostatin and neurotensin-binding sites was compared to that of immunolabeled sst2A and NTRH receptor subtypes, respectively. By light microscopy, immunoreactive sst2A receptors were either confined to neuronal perikarya and dendrites or diffusely distributed in tissue. By electron microscopy, areas expressing somatodendritic sst2A receptors displayed only low proportions of membrane-associated, as compared to intracellular, receptors. Conversely, regions displaying diffuse sst2A labeling exhibited higher proportions of membrane-associated than intracellular receptors. Furthermore, the former showed only low...

Development, comparative morphology and cornification of reptilian claws in relation to claws evolution in tetrapods Naturalis
Alibardi, L..
The development of claws in different reptiles and their cornification are analyzed using histological, ultrastructural and autoradiographic methods. Claws develop at the tip of digits in relation to the growth of the terminal phalanx and appear as modified scales. The apical epidermis of digit becomes thickened and is associated with a mesenchymal condensation or a dense mesenchyme. The dorsal side of the digit becomes the unguis while the ventral side becomes the sub-unguis. The corneous layer in the unguis is thicker than in the sub-unguis and accumulates hard-keratin while corneocytes remain separated or partially fused. Bundles of hard-keratin tend to accumulate in parallel orientation with respect to the surface and are directed toward the claw tip....

Mitochondrial DNA synthesis studied autoradiographically in various cell types in vivo BJMBR
Korr,H.; Kurz,C.; Seidler,T.O.; Sommer,D.; Schmitz,C..
It is generally accepted that mitochondria are able to proliferate even in postmitotic cells due to their natural turnover and also to satisfy increased cell energy requirements. However, no detailed studies are available, particularly with respect to specific cell types. Since [3H]-thymidine is incorporated not only into nuclear (n) DNA but also into the DNA of cytoplasmic mitochondria, an autoradiographic approach was developed at the light microscopy level in order to study basic questions of mitochondrial (mt) proliferation in organs of rodents in situ via the cytoplasmic incorporation of [3H]-thymidine injected into the animals 1 h before sacrifice. Experiments carried out on mice after X-irradiation showed that cytoplasmic labeling was not due to a...

Receptor localization of steroid hormones and drugs: discoveries through the use of thaw-mount and dry-mount autoradiography BJMBR
Stumpf,W.E..
The history of receptor autoradiography, its development and applications, testify to the utility of this histochemical technique for localizing radiolabeled hormones and drugs at cellular and subcellular sites of action in intact tissues. Localization of diffusible compounds has been a challenge that was met through the introduction of the "thaw-mount" and "dry-mount" autoradiographic techniques thirty years ago. With this cellular receptor autoradiography, used alone or combined with other histochemical techniques, sites of specific binding and deposition in vivo and in vitro have been characterized. Numerous discoveries, some reviewed in this article, provided information that led to new concepts and opened new areas of research. As an example, in...
