1. Dental anomalies in Didelphis albiventris (Mammalia, Marsupialia, Didelphidae) from Argentina, Brazil and Uruguay
ABSTRACT Dental anomalies have been investigated and reported for most orders of mammals, including marsupials. Previous works in Didelphis albiventris Lund, 1840 only described one kind of malformation or just a few observations from some collections, thus the type and presence of anomalies for this species was underestimated. The aim of this contribution i

2. Leaf phenotypic variation and developmental instability in relation to different light regimes
ABSTRACT For pioneer plants, shaded habitats represent a stressful condition, where sunlight exposure is below the optimum level and so leaves expand in order to intercept a greater amount of light. We investigated changes in both phenotypic variation and stress of Bauhinia brevipes in sunny and shaded microhabitats. Leaf area was used as a measure of phenot

3. Constant fluctuating asymmetry but not directional asymmetry along the geographic distribution of Drosophila antonietae (Diptera, Drosophilidae)
ABSTRACT The population dynamics of a species tends to change from the core to the periphery of its distribution. Therefore, one could expect peripheral populations to be subject to a higher level of stress than more central populations (the center–periphery hypothesis) and consequently should present a higher level of fluctuating asymmetry. To test these

4. Relationship between gall-midge parasitism, plant vigor, and developmental instability in Ouratea polygyna Engl (Ochnaceae) in a patch of a Brazilian Atlantic Forest
We tested the preference prediction of plant vigor hypothesis by examining the relationship between gall occurrence and leaf size. We also examined the effect of galls on leaf asymmetry, which is a measure of developmental instability. Gall occurrence did not increase with leaf size, thereby providing no support to the preference prediction. Galled leaves we

5. DNA repair diseases: what do they tell us about cancer and aging?
The discovery of DNA repair defects in human syndromes, initially in xeroderma pigmentosum (XP) but later in many others, led to striking observations on the association of molecular defects and patients' clinical phenotypes. For example, patients with syndromes resulting from defective nucleotide excision repair (NER) or translesion synthesis (TLS) present

6. Paternidade e subjetividade masculina em transformação : crise, crescimento e individuação. Uma abordagem junguiana / Fatherhood and male subjectivity in transformation : crisis, growth and individuation. A Jungian perspective
The purpose of this research is to broaden the understanding of how the experience of fatherhood is taking place at the present time, using a Jungian perspective: to find out what the impact of the experience of becoming a father is causing on mens developmental process and process of individuation. As a better understanding about the meaning of fatherhood n

7. Morphological Asymmetry in Ceratitis capitata (Diptera: Tephritidae) in natural population sample and laboratory sample submitted to different temperatures / Assimetria morfológica de Ceratitis capitata (Diptera: Tephritidae) em uma amostra de população natural e em amostras de laboratório submetidas a diferentes temperaturas
A assimetria de cinco estruturas corporais da mosca-das-frutas Ceratitis capitata foi analisada para uma avaliação se poderiam ser utilizadas como bioindicadores. As análises foram feitas em amostras de uma população natural e de uma população de laboratório. Adicionalmente, em amostras obtidas da população de laboratório, os índices de assimetri

8. Structural analyses of rab family GTPases and mechanism of Mafb regulation by the protein TIPRL / Analises estruturais de GTPases da familia RAB e mecanismo de regulção de MAFB pela proteina TIPRL
GTPases of the Rab family are responsible for the intracellular transport of vesicles. Each family member acts on a specific transport pathway and their function is regulated by GTP binding and hydrolysis, cycling between inactive (GDP-bound) and active (GTP-bound) forms. In this work, we describe the crystal structure of inactive and active forms of the GTP

9. Desenvolvimento neuropsicomotor nos primeiros 18 meses de vida de lactentes de alto risco
The aims of the present study were to describe the developmental outcome of high-risk infants during the first 18 months of age, investigate their association to the degree of risk for morbidity and verify the predictive power of three instruments of assessment of infant development. Fifty-six (56) high-risk infants were monitored through the application of

10. A latent variable model of developmental instability in relation to men's sexual behaviour.
A single trait's fluctuating asymmetry (FA) is expected to be a poor measure of developmental instability. Hence, studies that examine associations between FA and outcomes expected to covary with developmental instability often have little power in detecting meaningful relationships. One way of increasing the power of detecting relationships between developm
