1. ISOFLAVONOIDES DA TRIBO DALBERGIEAE: UMA CONTRIBUIÇÃO QUIMIOSSISTEMÁTICA PARA A SUBFAMÍLIA PAPILIONOIDEAE
Plants from Fabaceae family have several secondary metabolites and high biological potential. The subfamily Papilionoideae (Fabaceae) has 28 tribes, of which Dalbergieae comprises 49 genera and 1325 species. Isoflavonoids are chemotaxonomic markers of Papilionoideae and have important biological properties. This review describes the isoflavonoids and biologi

2. Differential replicative fitness of the four dengue virus serotypes circulating in Colombia in human liver Huh7 cells
ABSTRACT Dengue has been a significant public health problem in Colombia since the simultaneous circulation of the four dengue virus serotypes. The replicative fitness of dengue is a biological feature important for virus evolution and contributes to elucidating the behavior of virus populations and viral pathogenesis. However, it has not yet been studied in

4. Laboratory investigations in the diagnosis and follow-up of GH-related disorders
ABSTRACT In addition to auxiological, clinical and metabolic features measurements of growth hormone (GH) and insulin-like growth factor I (IGF-I) complement our tools in diagnosis and follow-up of GH-related disorders. While comparably robust during the pre-analytical phase, measurement and interpretation of concentrations of both hormones can be challengin

5. A ICONOGRAFIA LINEAR DA EVOLUÇÃO NA PERSPECTIVA DE DOCENTES QUE ATUAM NA EDUCAÇÃO BÁSICA
RESUMO: A marcha dos hominídeos tem influenciado fortemente a percepção das pessoas sobre a teoria evolutiva. Nesse artigo, analisamos se tal representação da evolução afeta a percepção dos educadores sobre Biologia e Ensino de Ciências. Através de uma pesquisa qualitativa, com a participação de professores de uma escola da periferia de São Pau

6. Efeito da idade, período e coorte de nascimento na incapacidade de idosos residentes na comunidade: Coorte de Idosos de Bambuí (1997-2012)
Resumo: A evolução temporal das prevalências de incapacidade em idosos pode ocorrer devido ao efeito de idade, período ou coorte. A idade é relacionada a fatores biológicos, o período ao contexto ambiental do sujeito e a coorte às exposições que o mesmo sofre desde o seu nascimento até o momento atual. O objetivo do estudo foi verificar quais dime

7. Diversity and evolution of Amazonian birds: implications for conservation and biogeography
Abstract: Amazonia has been a focus of interest since the early days of biogeography as an intrinsically complex and extremely diverse region. This region comprises an intricate mosaic that includes diverse types of forest formations, flooded environments and open vegetation. Increased knowledge about the distribution of species in Amazonia has led to the re

8. “A most bountiful source of inspiration:” Dobzhansky’s evolution of tropical populations, and the science and politics of genetic variation
Resumo Theodosius Dobzhansky tem sido estudado pelo modo como ele integrou o naturalismo de campo e a experimentação científica, que deram origem à síntese moderna, assim como a alavanca que ele deu ao conhecimento biológico para apoiar valores liberais e cosmopolitas em meio à Segunda Guerra Mundial e à Guerra Fria. Além disso, Dobzhansky tem sido

9. Science and evolution
Abstract Evolution is both a fact and a theory. Evolution is widely observable in laboratory and natural populations as they change over time. The fact that we need annual flu vaccines is one example of observable evolution. At the same time, evolutionary theory explains more than observations, as the succession on the fossil record. Hence, evolution is also

10. Pulmonary paracoccidioidomycosis: a case report of reactivation in a patient receiving biological therapy
Abstract Paracoccidioidomycosis is an endemic disease in Latin America that is rarely associated with immunosuppression and biological therapy. Herein, we report for the first time a case of pulmonary paracoccidioidomycosis reactivation after infliximab treatment. A 47-year-old man from Brazil received infliximab to treat psoriatic spondyloarthropathy and pr

11. Comments to Angulo et al. 2016 on “Sea-level fluctuations and coastal evolution in the state of Rio de Janeiro, southeastern - Brazil” by Castro et al. 2014
ABSTRACT Interpretation of sea-level indicators is essential when studying paleo sea-level fluctuations during the Holocene. Sea-level indicators may have different origins, such as geological (beachrocks) and biological (vermetids and barnacles). In order to reconstruct paleo sea-level, it is necessary to attribute an indicative meaning to each sea-level in

12. Remembering the past – studies on evolution done by the genetics group at Universidade Federal do Rio Grande do Sul (UFRGS)
Abstract After a brief introduction about the factors that are involved in science development, and world and Brazilian evolutionary genetics, the studies developed in Porto Alegre in this area were reviewed. Four periods in the development of this group were distinguished: (a) Origins and first expansion (1949-1961); (b) Second expansion (1962-1988); (c) Th
