13. Evolução bioquímica através de medidas seriadas de antígeno prostático específico (PSA) de pacientes submetidos a braquiterapia com implante de sementes de 125I no tratamento do adenocarcinoma de próstata / Biochemical outcome of patients with prostate adenocarcinoma treated with 125I seed implantation measured by serial dosages of prostate specific antigen
INTRODUÇÃO: Nos pacientes com câncer de próstata considerados de baixo risco, a braquiterapia de baixa taxa de dose (BBTD) utilizando sementes de 125I é uma excelente opção, com seguimento após o tratamento, devendo ser feito por meio de medidas seriadas de PSA. A avaliação de falha bioquímica após radioterapia, definida por elevação do PSA, te

14. Purification, partial characterization and role in lipid transport to developing oocytes of a novel lipophorin from the cowpea weevil, Callosobruchus maculatus
Lipid transport in arthropods is achieved by highly specialized lipoproteins, which resemble those described in vertebrate blood. Here we describe purification and characterization of the lipid-apolipoprotein complex, lipophorin (Lp), from adults and larvae of the cowpea weevil Callosobruchus maculatus. We also describe the Lp-mediated lipid transfer to deve

15. The seven-year preliminary results of brachytherapy with Iodine-125 seeds for localized prostate cancer treated at a Brazilian single-center
OBJECTIVE: To report the seven-year preliminary results of a single-center on brachytherapy with Iodine-125 seeds, used in combination with external beam radiotherapy in selected patients with localized prostate cancer (T1-T2). MATERIALS AND METHODS: All 105 patients treated by brachytherapy with Iodine-125 seeds, from January/1998 to December/2004, were ret

16. Desenvolvimento de procedimento utilizando processo de soldagem plasma para confecção de sementes de Iodo125 / Development of a procedure using plasma welding process to produce 125I seeds
The prostate cancer, which is the second cause of death by cancer in men, overcome only by lung cancer, is a problem of public health in Brazil. Brachytherapy is among the possible available treatments for prostate cancer, in which small seeds containing 125I radioisotope are implanted in the prostate. The seed consists of a titanium sealed capsule with 0.8

17. Biodistribution studies of bee venom and spider toxin using radiotracers
The use of radiotracers allows the understanding of the bioavailability process, biodistribution, and kinetics of any molecule labelled with an isotope, which does not alter the molecule's biological properties. In this work, technetium-99m and iodine-125 were chosen as radiotracers for biodistribution studies in mice using bee (Apis mellifera) venom and a t

18. Improved iodine-125 plaque design in the treatment of choroidal malignant melanoma.
The use and development of iodine-125 plaque therapy for choroidal malignant melanoma are described. Since 1975 experience has led to changes in plaque design and insertion techniques. Twenty-one patients were irradiated with local episcleral iodine-125 plaques. Three patients required a second plaque for tumour recurrence. Four eyes were enucleated because

19. Inhibition by iodine of the release of thyroxine from the thyroid glands of patients with thyrotoxicosis
A method has been devised which is free of many of the shortcomings of serial epithyroid counting techniques as an index of the rate of thyroid hormone secretion. By means of this method, the effect of treatment with Lugol's iodine on the rate of thyroidal secretion of thyroxine (T4) has been assessed in eight patients with thyrotoxicosis due to diffuse or m

20. Studies on gonococcus infection. VIII. 125Iodine labeling of gonococci and studies on their in vitro interactions with eukaryotic cells.
Intact gonococci (GC) have been labeled with 125iodine by the lactoperoxidase plus hydrogen peroxide procedure. The specific activities of types 2, 4, and 4 GC have been determined and are found to show small differences as follows: T4 greater than T2 greater than T4. 125I-labeled GC have been studied for their associations with both leukocytes and tissue cu

21. Formation of iodoprotein during the peripheral metabolism of 35,3′-triiodo-l-thyronine-125I in the euthyroid man and rat
3,5,3′-Triiodo-L-thyronine-125I (T3-125I) metabolism was studied in nine euthyroid human subjects on blocking doses of nonradioactive iodide. After the intravenous injection of T3-125I, the fractional disappearance rate of plasma radioactivity progressively disappearance rate of plasma radioactivity progressively decreased with time. Analysis of individual

22. Alterations in thyroid iodine release and the peripheral metabolism of thyroxine during acute falciparum malaria in man
Previous studies of thyroid function during various infections have yielded conflicting results, but most have suggested an acceleration of peripheral thyroxine (T4) turnover during the acute infectious illness. In the present studies, thyroid function was examined by a method allowing simultaneous analysis of both endogenous thyroidal release and peripheral

23. In vivo metabolism of complement: I. Metabolism of the third component (C′3) in acquired hemolytic anemia
The in vivo metabolism of purified third component of complement labeled with 125-iodine (C′3-125I) was studied in normal subjects and in patients with acquired hemolytic anemias. 27 such studies were performed; in addition, three studies were performed using C′3i, the biologically inactive reaction product of C′3.

24. Cholesterol balance and fecal neutral steroid and bile acid excretion in normal men fed dietary fats of different fatty acid composition
Six normal men were fed formula diets containing either highly saturated fat (cocoa butter, iodine value 32) or polyunsaturated fat (corn oil, iodine value 125). The sterol balance technique was used to compare the changes in serum cholesterol concentration with the excretion of fecal steroids. The method used for the analysis of fecal steroids was chemical,
