1. How strong was the bottleneck associated to the peopling of the Americas? New insights from multilocus sequence data
Abstract In spite of many genetic studies that contributed for a deep knowledge about the peopling of the Americas, no consensus has emerged about important parameters such as the effective size of the Native Americans founder population. Previous estimates based on genomic datasets may have been biased by the use of admixed individuals from Latino populatio

2. Molecular characterization of Brazilian equid herpesvirus type 1 strains based on neuropathogenicity markers
Partial nucleotide sequences of ORF72 (glycoprotein D, gD), ORF64 (infected cell protein 4, ICP4) and ORF30 (DNA polymerase) genes were compared with corresponding sequences of EHV-1 reference strains to characterize the molecular variability of Brazilian strains. Virus isolation assays were applied to 74 samples including visceral tissue, total blood, cereb

3. Molecular cloning of a hyaluronidase from Bothrops pauloensis venom gland
Background Hyaluronate is one of the major components of extracellular matrix from vertebrates whose breakdown is catalyzed by the enzyme hyaluronidase. These enzymes are widely described in snake venoms, in which they facilitate the spreading of the main toxins in the victim’s body during the envenoming. Snake venoms also present some variants (hyaluron

4. Growth and microcystin production of a Brazilian Microcystis aeruginosa strain (LTPNA 02) under different nutrient conditions
Cyanobacteria are prokaryotic and photosynthetic organisms, which can produce a wide range of bioactive compounds with different properties; including a variety of toxic compounds, also known as cyanotoxins. In this work, we describe the isolation of seven cyanobacterial strains from two reservoirs in São Paulo State, Brazil. Seven different chemical varian

5. Produção de proteases e fator hemolítico e switching fenotípico em Candida spp
Yeast species belonging to the genus Candida are responsible for the majority of fungal infections in humans. The aim of the present study was to determine haemolytic and protease activities of clinical isolates of Candida parapsilosis and Candida tropicalis obtained from anatomically distinct sites, and to determine the frequency of phenotypic switching in

6. Antimycobacterial neolignans isolated from Aristolochia taliscana
Tuberculosis (TB - Mycobacterium tuberculosis) is an ancient infectious disease that has appeared once again as a serious worldwide health problem and now comprises the second leading cause of death resulting from a single infection. The prevalence of multidrug resistance (MDR) TB is increasing and therapeutic options for treatment are not always accessible;

7. Characterization of variants of Bradyrhizobium elkanii and B. japonicum and symbiotic behaviour in soybeans / Caracterização de variantes de estirpes de Bradyrhizobium elkanii and B. japonicum e comportamento simbiótico em soja
Variantes em estirpes de rizóbio usadas na produção de inoculantes não são desejáveis e podem propiciar resultados inesperados na inoculação da leguminosa. Estudou-se a variabilidade nas características fenotípicas e a estabilidade genética das estirpes de Bradyrizobium recomendadas para a inoculação em soja. Foram isolados variantes com morfolo

8. GRAFT OR HOMOLOGOUS IMPLANT IN THE CORRECTION OF FEMORAL SEGMENTAL BONE DEFECT IN DOGS ASSOCIATED TO INOCULATION OF BONE MARROW MONONUCLEAR CELL FRACTION / ENXERTO OU IMPLANTE HOMÓLOGO NA CORREÇÃO DE DEFEITO ÓSSEO SEGMENTAR FEMORAL EM CÃES ASSOCIADO A INOCULAÇÃO DA FRAÇÃO DE CÉLULAS MONONUCLEARES DA MEDULA ÓSSEA
Bone defects due to trauma, postoperative and mutilating surgery complications, associated to removal of neoplasia, are part of the routine of hospitals and veterinary clinics. Bone grafts, within all their variants, represent the main viable alternative in the structural correction of great bone losses. Currently, the search for alternatives to correct thes

9. Antigenic and genomic characterization of adenovirus associated to respiratory infections in children living in Northeast Brazil
From January to December 1998, nasopharyngeal aspirates were obtained from 482 children with acute respiratory infections attended in emergence department and wards of a teaching hospital in the city of Salvador, Brazil. The samples were tested for the presence of adenovirus by isolation in tissue culture and indirect immunofluorescence assay. Eleven adenovi

10. O objeto direto anafórico no dialeto rural afro-brasileiro.
This dissertation analyzes, in a sociolinguistics perspective, the strategies of realization of the anaphoric direct object in the rural Brazilian-Afro dialect, focusing on the variants that make the Brazilian Portuguese (BP) and the European Portuguese (EP) linguistically distant: the empty category and the use of the lexical pronoun (he/she). Its believed

11. Cytogenetics and immature embryo culture at Embrapa Trigo breeding program: transfer of disease resistance from related species by artificial resynthesis of hexaploid wheat (Triticum aestivum L. em. Thell)
Worldwide wheat (Triticum aestivum L. em. Thell, 2n = 6X = 42, AABBDD) breeding programs aim to reorganize genotypes to achieve better yields, environmental adaptation and food quality. The necessary interdisciplinarity for breeding purposes requires an accurate choice of the most appropriate cellular and/or molecular strategies available to be integrated wi

12. PURIFICATION OF alfa-LACTALBUMIN USING PEPTIDES AS AFFINITY CHROMATOGRAPHY LIGANDS
A method for the purification of alfa-lactalbumin from whey protein isolate solutions using a hexapeptide ligand has been developed. The peptide WHWRKR was isolated from a peptide library generated by combinatorial chemistry, and displays affinity to alfa-lactalbumin. Other proteins from whey protein isolate bound nonspecifically to the resin used. Different
