1. Cytogenetic mapping of the ALMT (aluminum-activated malate transporter) gene in wheat genotypes
ABSTRACT: Presence of the ALMT1 (aluminum-activated malate transporter) gene confers resistance to aluminum toxicity in Triticum aestivum (common wheat). No resistant cultivars of Triticum turgidum ssp. Durum Desf. (durum wheat) have been registered in Brazil. The aim of this study was to map the ALMT1 through application of the FISH (fluorescence in situ hy

2. Cytoarchitecture of the superior olivary complex of three neotropical species of bats (Noctilio leporinus, Phyllostomus hastatus and Carollia perspicillata) with different foraging behavior
Resumo O entendimento da ecolocalização pelo estudo de diferentes núcleos auditivos de morcegos pode ser um elo importante na elucidação das inúmeras questões que surgem em relação ao seu comportamento de forrageamento. O complexo olivar superior (SOC) é o principal centro de processamento das pistas binaurais usadas na localização do som, já qu

3. Grazing of particle-associated bacteria-an elimination of the non-viable fraction
Abstract Quantification of bacteria being grazed by microzooplankton is gaining importance since they serve as energy subsidies for higher trophic levels which consequently influence fish production. Hence, grazing pressure on viable and non-viable fraction of free and particle-associated bacteria in a tropical estuary controlled mainly by protist grazers wa

4. Cell cycle synchronization and BrdU incorporation as a tool to study the possible selective elimination of ErbB1 gene in the micronuclei in A549 cells
Lung cancer often exhibits molecular changes, such as the overexpression of the ErbB1 gene that encodes epidermal growth factor receptor (EGFR). ErbB1 amplification and mutation are associated with tumor aggressiveness and low response to therapy. The aim of the present study was to design a schedule to synchronize the cell cycle of A549 cell line (a non-sma

5. Avaliação da concentração de elementos químicos tóxicos na merenda escolar de crianças da cidade de Ribeirão Preto e estimativa de suas ingestões diárias / Assessment of toxic chemicals concentration in the school
Chemical\ s contamination in the environment is a growing worldwide problem. Many of these chemical elements, including Cd, Pb and As are toxic to humans. According to the World Health Organization (WHO), 90% of the intake of these toxic elements occurs through the food consumption (Tavares et al., 1992; Virga et al., 2007). Therefore, the estimation of expo

6. Design, construction, and analysis of specific zinc finger nucleases for microphthalmia - associate transcription factor
This work studied the design, construction, and cleavage analysis of zinc finger nucleases (ZFNs) that could cut the specific sequences within microphthalmia - associate transcription factor (mitfa) of zebra fish. The target site and ZFPs were selected and designed with zinc finger tools, while the ZFPs were synthesized using DNAWorks and two-step PCR. The Z

7. Haemulidae, modelo cariotípico de estase evolutiva
Os perciformes constituem o maior e mais diversificado grupo de peixes. Uma parcela considerável de suas espécies apresenta um marcante conservadorismo cromossômico exibindo um padrão caracterizado por 2n=48a, NF=48, que tem sido apontado como uma condição basal para a Ordem. Blocos heterocromáticos reduzidos e RONs simples são característicos para

8. Estudo citogenético em duas espécies da família Callichthyidae (Callichthyinae, Siluriformes) da bacia do Rio de Contas/Bahia
The family Callichthyidae is included in the order Siluriformes, is widely distributed by the Neotropical region and comprises 194 species and eight genera, distributed in two subfamilies, Corydoradinae and Callichthyinae. Aiming to expand the cytogenetics information of the ichthyofauna of the eastern Atlantic basins, this work was done in Callichthys calli

9. Ultrastructure of Myxobolus brycon n. sp. (Phylum Myxozoa), parasite of the Piraputanga Fish Brycon hilarii (Teleostei) from Pantanal (Brazil).
Light and electron microscopy studies of a myxosporean, parasitizing the gill filaments of the freshwater fish Brycon hilarii (Valenciennes, 1850) (Characidae) collected in the Paraguay River (181490S, 571390W) (Pantanal), Brazil, is described. This parasite produces spherical to ellipsoidal polysporic histozoic plasmodia (Pmd) (up to ~ 180 mm in diameter) d

10. Do Omega-3 fatty acids prevent atrial fibrillation after open heart surgery? A meta-analysis of randomized controlled trials
OBJECTIVES: N-3 polyunsaturated fatty acids have been proposed as a novel treatment for preventing postoperative atrial fibrillation due to their potential anti-inflammatory and anti-arrhythmic effects. However, randomized studies have yielded conflicting results. The objective of this study is to review randomized trials of N-3 polyunsaturated fatty acid us

11. Isolamento e caracterização de DNA repetitivo de Physalaemus cuvieri e localização cromossômica em espécies do grupo "cuvieri" de Physalaemus (Amphibia, Anura, Leiuperidae) / Isolation and characterization of repetitive DNA of Physalaemus cuvieri and chromosome location in species of the group of cuvieri Physalaemus (Amphibia, Anura, Leiuperidae)
O gênero Physalaemus é atualmente constituído de 42 espécies, distribuídas em sete grupos. No grupo de Physalaemus cuvieri, além dessa, estão alocadas outras oito espécies. Estudos citogenéticos disponíveis até momento para algumas espécies do gênero nos mostram um número diplóide de 2n = 22, sendo a morfologia cromossômica similar entre elas

12. Analysis of the association between spawning time QTL markers and the biannual spawning behavior in rainbow trout (Oncorhynchus mykiss)
The rainbow trout is a salmonid fish that occasionally exhibits broodstocks with biannual spawning behavior, a phenomenon known as a double annual reproductive cycle (DARC). Spawning time quantitative trait loci (SPT-QTLs) affect the time of the year that female rainbow trout spawn and may influence expression of the DARC trait. In this study, microsatellite
