1. Storage protein variability in natural populations of maté (Ilex paraguariensis) in Brazil
RESUMO: A variabilidade de proteínas de reserva das sementes foi analisada em 168 árvores de quatro populações naturais de erva-mate (Ilex paraguariensis) dos estados brasileiros Rio Grande do Sul, Santa Catarina, Paraná e Mato Grosso do Sul. Estes marcadores foram utilizados para estimar o grau de diferenciação entre e dentro da espécie porque são

2. Detection of Specific Polypeptide(s) Synthesized during the Sequential Stages of Differentiation in Dioscorea species
ABSTRACTThe present investigation was aimed to detect the specific polypeptide(s) appeared during the sequential stages of differentiation. Among different explants, only nodal explants showed good results for callusing. Depending on the fresh and dry weight, best callus growth was observed on MS medium supplemented with NAA (2.5 mg/L) inDioscorea alata and

3. Cycle modulation of insulin-like growth factor-binding protein 1 in human endometrium
Endometrium is one of the fastest growing human tissues. Sex hormones, estrogen and progesterone, in interaction with several growth factors, control its growth and differentiation. Insulin-like growth factor 1 (IGF-1) interacts with cell surface receptors and also with specific soluble binding proteins. IGF-binding proteins (IGF-BP) have been shown to modul

4. Structural and regulatory differences in amylase isoenzymes in germinating Brazilian barley cultivars
The amylase electrophoretic patterns of 10 Brazilian brewing-barley varieties with different malting grades and diastatic power were analyzed during the 7-day germination which occurs during the malting process. Intra and inter-variety genetic variability was observed at both the structural and regulatory level. In the first few days after germination all va

5. Variación geográfica de Ninia atrata en Colombia (Colubridae: Dipsadinae)
The distribution and geographic variation of Ninia atrata in Colombia are investigated based on 128 specimens from more than 24 localities. The Colombian specimens exhibit considerable polymorphism in color patterns. Differentiation occurs between cis-Andean and trans-Andean populations in coloration and form of the nape band and in seven of twelve morphomet

6. Karyotype differentiation of four Cestrum species (Solanaceae) revealed by fluorescent chromosome banding and FISH
The karyotypes of four South American species of Cestrum (C. capsulare, C. corymbosum, C. laevigatum and C. megalophylum) were studied using conventional staining, C-CMA/DAPI chromosome banding and FISH with 45S and 5S rDNA probes. The karyotypes showed a chromosome number of 2n = 2x = 16, with metacentric chromosomes, except for the eighth submeta- to acroc

7. Caracterização bioquímica de células sadias e neoplásicas através de espectroscopia vibracional / Biochemical characterization of healthy and neoplastic cells by vibrational spectroscopy
The molecular mechanisms and changes leading to the development and progression of cancers are extremely complex. FTIR spectroscopy can detect biochemical features of biological materials, enabling the important characterization and differentiation of cells. By looking at the individual absorption bands, it is possible to spot similarities and differences be

8. Physical training, inflammatory process and adaptative condition / Treinamento fisico, processo inflamatorio e adaptação
Physical exercise can cause trauma to biological structures as skeletal muscle, joints, bone and several other tissues. Training in a chronic way and considering training-recovery relationship can lead to a coherent sequence of trauma and consequently to organic adaptive condition (Functional Overreaching - FOR). On the other hand an imbalance between traini

9. Detecção de mudanças no uso e na cobertura do solo em uma série temporal de imagens da Região da Campanha do Rio Grande do Sul
A detecção de mudanças no uso e na cobertura do solo pode ser considerada a função do sensoriamento remoto que agrega uma dimensão temporal à análise das informações contidas nas imagens. Ao confrontá-las duas a duas, para identificar, localizar e qualificar as transformações que ocorreram na cobertura e no uso do solo em determinados espaço e

10. Classificação fitofisionômica do cerrado no Parque Nacional da Chapada dos Veadeiros, GO, com a aplicação de uma análise combinatória com filtros adaptativos em imagens TM Landsat
The soil fertility and water availability are some of the many factors which controls the Cerrado biome vegetation and are in charge of a great diversity of phytophysiognomies that encompass fields, savanna or forest formations. The vegetal mass amount variation occurs according to the vegetation formations and takes its effects over the spectral signatures

11. Partial biochemistry characterization and obtention of low molecular weight acid phosphatase from osteoblasts cultures / Perfil da proteína tirosina fosfatase de baixo peso molecular em células osteoblásticas
Events as phosphorilation and desphosphorilation are experienced in cell growth and differentiation processes. Tyrosine phosphatases proteins are involved in these processes. These enzymes are found in animals, plants and occur in multiple forms, differing in relative molecular weight, substrate specificity and sensitivity to inhibitors. The enzymes that hav

12. Cytogenetics of populations and species of Physalaemus cuvieri group (Anura, Leiuperidae) / Citogenetica de populações e especies de Physalaemus do grupo "cuvieri" (Anura, Leiuperidae)
The genus Physalaemus is composed by 41 species distributed in seven groups: albifrons, cuvieri, deimaticus, gracilis, henselii, olfersii and signifer. Nine species compose the group cuvieri but just P. cuvieri had already been karyotyped in details. Expressive intra and interpopulational variation related to the localization
