3. Physicochemical characteristics and fibril-forming properties of collagen from paddlefish (Polyodon spathula) and globefish (Fugu flavidus) skin byproducts
Abstract Acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) from the skin byproducts of paddlefish (ASC-P and PSC-P) and globefish (ASC-G and PSC-G) were purified and characterized. The imino acid contents of ASC-P, PSC-P, ASC-G and PSC-G were 194.1, 197.9, 186.4 and 189.7 residues/1000 residues, respectively. SDS-polyacrylamide gel electrophoresi

4. Analysis of serum cortisol levels by Fourier Transform Infrared Spectroscopy for diagnosis of stress in athletes
Abstract Introduction Fourier-transform infrared (FT-IR) spectroscopy is a technique with great potential for body fluids analyses. The aim of this study was to examine the impact of session training on cortisol concentrations in rugby players by means of infrared analysis of serum. Methods Blood collections were performed pre, post and 24 hours after of r

5. Growth and Characterization of Graphene on Polycrystalline SiC Substrate Using Heating by CO2 Laser Beam
The thermal decomposition of silicon carbide (SiC), with the subsequent formation of graphene, can be achieved by heating treatment. Several heating processes have been applied for this purpose by using SiC, either in form of powder particles or monocrystalline substrate. In this work, instead of using an expensive commercially available SiC wafer, a polycry

6. Safflower oil: an integrated assessment of phytochemistry, antiulcerogenic activity, and rodent and environmental toxicity
Gastric ulcers are a significant medical problem and the development of complications lead to significant mortality rates worldwide. In Brazil, Carthamus tinctorius L., Asteraceae, seeds essential oil, the safflower oil, is currently used as a thermogenic compound and as treatment for problems related to the cardiovascular system. In this study, by Raman spe

7. Planejamento de inibidores baseado em fragmentos moleculares para a enzima gliceraldeído-3-fosfato desidrogenase de Trypanosoma cruzi / Design of inhibitors through fragment-based drug discovery for the enzyme glyceraldehyde-3-phosphate dehydrogenase from Trypanosoma cruzi
Chagas disease is a parasitic illness endemic in Latin America caused by the trypanosomatid parasite Trypanosoma cruzi that spreads around the world due to people migration. Nowadays, Benznidazole and Nifurtimox (banned in Brazil), are used for the treatment of this disease but causes severe side effects to patients. Recently, three new molecules have reache

8. Aglomerados estelares da Pequena Nuvem de Magalhães / Star clusters in the Small Magellanic Clouds
Análise de idades e metalicidades de aglomerados estelares nas Nuvens de Magalhães traz informação para estudos sobre a evolução química e dinâmica das Nuvens. Usando-as como calibradores de modelos de populações estelares simples, esse tipo de análise é útil também para o estudo de outras galáxias. Um dos objetivos deste trabalho é derivar i

9. Electron magnetic resonance in studies of biologically-relevant systems. / Ressonância magnética eletrônica no estudo de sistemas de interesse biológico
In this work, we made use of the Electron Paramagnetic Resonance (EPR) spectroscopy along with the so-called reporter group technique and extensive spectral simulations by means of the software NLSL to investigate the interaction of nicotine with model membranes. Besides that we also employed Ferromagnetic Resonance (FMR), which is a technique similar in man

10. Propriedades estruturais e vibracionais de nanocristais de TiO2 dispersos em matriz vítrea porosa / Vibrational and structural properties of TiO2 nanocrystals dispersed into porous glass matrix
Nanostructured materials are the subject of intense investigation due to their remarkable properties as compared their bulk counterparts. The size-induced phenomena are interesting their own and open unique opportunities not only for using these properties in novel applications but also for improving the current technology. In this scenario integrated chemic

11. Synthesis of carbon nanostructures by using thermal plasma torch
Some recent results concerning the synthesis of carbon nanostructures in a thermal plasma generating by a plasma torch are presented. Several tests were carried out in different operational conditions. The plasma was formed with argon and different gas mixtures of argon-acetylene or argon-methane to which some catalyst materials (ferrocene and cerium oxide)

12. X-ray scattering studies of the metastable ferroelectric phase in KDP induced by static electric field
Potassium dihydrogen phosphate presents a ferroelectric phase below 122 K and a paraelectric phase for T > 122 K. X-ray scattering measurements were performed in order to verify the mechanism of the phase transition from point group C2v19 to C2v¹19 at 119 K induced by DC electric field; in other words, a change of the local site symmetries of the phosphate
