1. The Tatuí Formation as a source of raw material in the ceramic pole of Santa Gertrudes (SP)
Abstract The importance of the Santa Gertrudes Ceramic Complex (SGCC) in the ceramic market is directly associated with the high quality of the Corumbataí Formation clays used in the manufacture of its products. Although the volumetric capacity of the Corumbataí Formation is able to meet the SGCC demand for the coming years, its industries are always in se

2. A dinosaur ilium from the Late Triassic of Brazil with comments on key-character supporting Saturnaliinae
Abstract: Discoveries in Carnian-aged rocks are establishing a rich and diverse dinosaurian fauna at the so-called ‘dawn of the age of dinosaurs’ in the Late Triassic of Western Gondwana. Accordingly, Brazilian strata from the Candelária Sequence have contributed extensively to this trend. Here, we present a new dinosaurian specimen (CAPPA/UFSM 0200) fr

3. Cell migration inhibition activity of a non-RGD disintegrin from Crotalus durissus collilineatus venom
Abstract Background: In recent decades, snake venom disintegrins have received special attention due to their potential use in anticancer therapy. Disintegrins are small and cysteine-rich proteins present in snake venoms and can interact with specific integrins to inhibit their activities in cell-cell and cell-ECM interactions. These molecules, known to inh

4. Three-dimensional structure and cytokine distribution of platelet-rich fibrin
OBJECTIVES: Previous reports have revealed that several cytokines (including platelet-derived growth factor-BB, transforming growth factors-β1 and insulin-like growth factor-1) can enhance the rate of bone formation and synthesis of extracellular matrix in orthopaedics or periodontology. This study aimed to determine the concentration of cytokines within p

5. Cloning, characterization and expression of a novel laccase gene Pclac2 from Phytophthora capsici
Laccases are blue copper oxidases (E.C. 1.10.3.2) that catalyze the one-electron oxidation of phenolics, aromatic amines, and other electron-rich substrates with the concomitant reduction of O2 to H2O. A novel laccase gene pclac2 and its corresponding full-length cDNA were cloned and characterized from Phytophthora capsici for the first time. The 1683 bp ful

6. In vitro antimicrobial activity and characterization of mangrove isolates of streptomycetes effective against bacteria and fungi of nosocomial origin
The study aimed at determining the in vitro antimicrobial activity of alkaliphilic and halotolerant actinomycetes isolated from a mangrove ecosystem and identification of a potent strain. Twenty five isolates of actinomycetes were isolated from the sediment samples of Valapattanam mangrove swamp in Kerala, India. Antimicrobial activity of four selected actin

7. Nucleation and growth process of sodalite and cancrinite from kaolinite-rich clay under low-temperature hydrothermal conditions
The synthesis of low-silica zeotypes by hydrothermal transformation of kaolinite-rich clay and the nucleation and growth processes of sodalite and cancrinite in the system Na2O-Al2O3-SiO2-H2O at 100 °C were investigated. The synthesis products were characterized by X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), Fourier transform infr

8. Caracterização funcional e estrutural de uma nova fosfolipase A2 ácida de Bothrops moojeni / Functional and structural characterization of a new acidic phospholipase A2 from Bothrops moojeni
The phospholipase A2 (PLA2s) are enzymes that induce various pharmacological effects and usually correspond to a higher percentage of the protein content of snake venoms. Thus, isolation, biochemical, functional and structural characterization of PLA2s may generate important information for a better understanding of the pharmacological effects and toxicity i

9. Territórios heterocromáticos em Triatoma infestans Klug e Panstrongylus megistus (Burmeister) : composição, identificação de marcadores epigenéticos e resposta a inibidores de deacetilases de histonas / Heterochromatic territories in Triatoma infestans Klug and Panstrongylus megistus (Burmeister) : composition, identification of epigenetic markers and response to histone deacetylase inhibitors
A cromatina pode existir em núcleos interfásicos em dois estados distintos: como eucromatina e como heterocromatina, podendo ser esta constitutiva ou facultativa. Em células somáticas do final da fase ninfal dos hemípteros reduviídeos Triatoma infestans e Panstrongylus megistus há núcleos grandes, poliploides, nos quais a heterocromatina apresenta-se

10. Worldwide genetic variation at the 3´-UTR region of the LDLR gene : possible influence of natural selection
The low density lipoprotein receptor gene (LDLR) contains many Alu insertions, and is especially Alu-rich at its 3 -untranslated region (3 -UTR). Previous studies suggested that the LDLR 3 -UTR could regulate gene expression by the stabilization of its mRNA. Given the faster Alu evolutionary rate, and wondering about its consequences in a possibly regulatory

11. Caracterização e expressão do gene SERK durante a indução de embriogênese somática em soja / Characterization and expression of SERK gene during induction of somatic embryogenesis in soybean
Somatic embryogenesis is a useful tool for plant propagation and a suitable model system for deciphering early events during embryo development. Molecular and genetic studies focused in plant development have reported the involvement of SERK (Somatic Embryogenesis Receptor Kinase) gene in the acquisition of embryogenic competence. In order to increase the ef

12. Molecular characterization of beta-tubulin from Phakopsora pachyrhizi, the causal agent of Asian soybean rust
β-tubulins are structural components of microtubules and the targets of benzimidazole fungicides used to control many diseases of agricultural importance. Intron polymorphisms in the intron-rich genes of these proteins have been used in phylogeographic investigations of phytopathogenic fungi. In this work, we sequenced 2764 nucleotides of the β-tubulin gen
