1. Expression of FoxP3 in different forms of leprosy and reactions
RESUMO Embora as células T reguladoras (Treg) sejam importantes na regulação imunológica de vários processos patológicos, o papel delas na imunologia da hanseníase ainda precisa ser mais bem avaliado. O objetivo deste trabalho é quantificar o nuclear transcription factor P3 (FoxP3), principal marcador de células Treg, nas diferentes formas de hansen

2. Impact of co-blocking the costimulatory signals on immune-related genes after high-risk rabbit corneal allograft using 2nd-generation DNA sequencing technology
Abstract The aim of this study was to evaluate the impact and mechanism of co-blocking of costimulatory signals CD28-B7-CD40-CD40L during immune allograft rejection. Forty-eight recipient rabbits were prepared as a high-risk corneal allograft model. After surgery, the animals were randomly divided into: control group, MR1 group, anti-B7 group, and co-blockin

3. American Space Nuclear Electric Systems
ABSTRACT: Since the 1960's the United States of America has launched several space missions using nuclear technology as a mean for propulsion and power supply. The majority of the American nuclear powered spacecrafts were based in radioisotope generators, with the exception of the SNAP-10A (1965), which was the only American reactor ever launched. However, s

4. Technology, politics, and development: domestic criticism of the 1975 Brazilian-West German nuclear agreement
Abstract The article analyzes the domestic debate regarding the Brazil-West Germany nuclear agreement of 1975. A number of scientists and opposition politicians sought to use the apparent failings of the agreement to critique the military’s claims regarding the deal’s contribution to Brazilian economic development and nuclear status. While limited in its

5. Diagrama de fases experimental Fe-Sn-Zr. Nuevos resultados del corte isotérmico de 800 °C
ABSTRACT The Zr-based alloys are extensively applied in the field of nuclear technology. Alloyed with Sn and Fe, Zr is the main element in the zircaloy-type alloys, currently vastly used as structural elements and as containers of burnable elements in nuclear reactors. This ternary metallurgical system is also a component of more recently developed alloys su

6. The Defense-Development Nexus: Brazilian Nuclear Policy under the Workers’ Party Administrations
Abstract Focusing on the Workers’ Party administrations (2003-2016), we claim that, among other crucial ideas and interpretations, the framing process of the Brazilian nuclear program by the ruling elites can be understood through the notion of a mendes-pimentelense nexus. To support that claim, Section II discusses the developmentalist thinking in Brazil.

7. Molecular Cloning and Mrna Expression Analysis of Sichuan White Goose (Anser Cygnoides) Chrebp Gene
ABSTRACT The carbohydrate response element-binding protein (ChREBP) is an important nuclear factor that regulates glycolysis and de novo lipogenesis. However, the role of ChREBP in fatty liver development in geese remains unclear. In order to understand the function of ChREBP in lipid metabolism of geese, we first cloned the complete cDNA of the ChREBP of th

8. Development of a new model of actinic enteritis in rats using a cobalt-60 open source and a protection device as a collimator
Abstract Purpose: To describe a new model of actinic enteritis that does not use radiotherapy machines. Methods: Sixteen Wistar rats were divided into four groups, consisting of four animals each: control (group A), two weeks after irradiation (group B), five weeks after irradiation (group C) and eight weeks after irradiation (group D). Animals were given

9. International Co-operation in Science and Technology: Concepts, Politics, and Dynamics in the Case of Argentine-Brazilian Nuclear Co-operation
Abstract Abstract: This article discusses the political dynamic of agenda-setting in the subfield of international nuclear co-operation, within an analytical framework that integrates the literature on international co-operation in science and technology, international nuclear co-operation, and foreign policy analysis. It presents the emblematic case of Arg

11. Determination of Aldrin Purity Using a Combination of the Mass Balance Approach and Quantitative NMR
This paper describes the studies performed to determine the purity of aldrin samples, an organochlorine pesticide, using the mass balance approach. The organic impurities were identified and quantified by gas chromatography-mass spectrometry (GC-MS), gas chromatography with flame ionization detection (GC-FID) and gas chromatography with electron capture dete

12. Nuclear governance in Latin America
The article provides an outlook of the regional relations concerning nuclear technology in Latin America. For that purpose, we initially discuss the historic relationship of the Latin American countries with the set of rules, norms, principles and organizations involved in nuclear governance. The article provides an analysis of the connection between the mul
