1. Sistemas neuromodulatórios: implicações fisiopatológicas / Neuromodulatory systems: patophysiologic implications
Adenosine has been shown to modulate cardiovascular control at the levels of the nucleus tractus solitarii (NTS). This study shows the distribution and density of adenosine A1 receptor within the nucleus tractus solitarii (NTS) of Wistar Kyoto (WKY) and spontaneously hypertensive (SHR) rats from birth to adulthood (1,15,30 and 90 day-old). [3H]DPCPX was used

2. "Efeito modulatório da nicotina sobre a neurotransmissão em núcleos encefálicos responsáveis pelo controle cardiovascular em ratos geneticamente hipertensos e normotensos" / "Nicotine modulatory effects on neurotransmiter systems in the cardiovascular brain areas of spontaneously hypertensive and normotensive rats"
Nicotine is one of the most important agents for cardiovascular diseases in tobacco smoking. This alkaloid acts in the blood stream, but it also crosses the blood-brain-barrier and participate in the regulation of pivotal neurotransmitter systems for the blood pressure control and, eventually, for hypertension development. In this context, nicotine abuse cou

3. Efeito da vimblastina na incorporação de 3H-Glicina em proteinas do ligamento periodontal de incisivos de camundongos em erupção normal e desimpedidas
The effect of vinblastine on the metabolism of proteins of the periodontal ligament (PL) of mice incisors was studied through the incorporation of ³H-glicine as revealed by radioautography. Male, adult mice, with the left inferior incisors in unimpeded eruption and the right ones in normal eruption, received intraperitoneally a single dose of vinblastine of

4. Ameloblastos secretores : secreção, absorção e reutilização de amelogenina marcada com 3H-prolina, visualizadas atraves de radioautografia
Two groups of mice 12 hrs old were sacrificed from 1 to 144 hours after the injection of 3H-Thymidine or 3H-Proline. One group of 21 animaIs, each weighing on average 1,5 g.were injected with a single dose of 1 ~Ci/g body weight of 3H-Thymidine and the other group of 27 animaIs each weighing on average 1,4 g.received a single dose of 5 ~Ci/g body weight of 3

5. Contribuição ao estudo dos efeitos da hemidescorticação sobre a tireoide e desenvolvimento de dentes e mandibula, erupção dental e incorporação de 3H-glicina no ligamento periodontal
Previous resul ts have shown that hemidecortication yields a retarded eruption rate of rats incisors. To study the protein metabolism of the periodontal ligament (PL) in such a condition, 12 hemidecorticated (HD) and 9 control young male rats received a single dose of 2.5 uCi of 3H glycine and were sacrificed 20 min., 1, 2 and 4 h after the injection. In ano

6. Replication of herpesvirus DNA. III. Rate of DNA elongation.
The rate of pseudorabies virus DNA elongation was measured by three different techniques: density shift experiments, radioautography examined by light microscopy, and radioautography examined by electron microscopy. The rate of the fork movement at 37 degrees C was estimated to be approximately 1 micron/min.

7. NH2-terminal specificity and axonal localization of adrenocorticotropin binding sites in rat median eminence.
Adrenocorticotropin binding sites in the rat median eminence have been localized in vivo. These binding sites occur in the basalar zone, which is rich in axonal endings. Using competitive binding and quantitative light-microscope radioautography, we found that the median-eminence binding site, in contradistinction to the adrenal receptor, binds specifically

8. Polypeptide hormone binding sites in vivo: initial localization of 125I-labeled insulin to hepatocyte plasmalemma as visualized by electron microscope radioautography.
The rationale of the specific-binding assay was applied to the detection of the liver insulin receptor in vivo. Quantitative electron microscope radioautography indicated that, 3 min after an intraportal injection, 125I-insulin was exclusively located to the hepatocyte plasmalemma.

9. Electron Microscopic Radioautography of HeLa Cells Infected with Adenovirus
Harford, Carl G. (Washington University, St. Louis, Mo.), and Alice Hamlin. Electron microscopic radioautography of HeLa cells infected with adenovirus. J. Bacteriol. 89:1540–1547. 1965.—Because intracellular particles of adenovirus are not seen by light microscopy, radioautography with tritiated thymidine was carried out with an electron microscope.

12. Expression of Purine Overproduction in a Series of 8-Azaguanine-Resistant Diploid Human Lymphoblast Lines
For study of the basis of an X-linked form of gout in man, several clonal lines deficient in hypoxanthine-guanine phosphoribosyltransferase (EC 2.4.2.8) were selected from the human lymphoblast line WI-L2 by spontaneous and mutagen-induced resistance to 10 μM 8-azaguanine. Three groups could be defined: (1) clones with less than 1% of normal enzyme activity
