1. Evaluation of 10-minute post-injection 11C-PiB PET and its correlation with 18F-FDG PET in older adults who are cognitively healthy, mildly impaired, or with probable Alzheimer’s disease
Objective: Positron emission tomography (PET) allows in vivo evaluation of molecular targets in neurodegenerative diseases, such as Alzheimer’s disease. Mild cognitive impairment is an intermediate stage between normal cognition and Alzheimer-type dementia. In vivo fibrillar amyloid-beta can be detected in PET using [11C]-labeled Pittsburgh compound B (11C

2. What is the best Cardiovascular Risk Score for the Brazilian Population?
Malaria, a parasitic infection caused by Plasmodium falciparum, is a serious global public health problem. The enzyme enoyl-acyl carrier protein (ACP) reductase present in a limiting step in the biosynthesis of fatty acids type II was used to search for novel molecules with potential inhibitor by virtual screening techniques. A flavonoid library obtained in

4. The usefulness of GGE biplot methodology for line × tester data of maize inbred lines
ABSTRACT The genotype + genotype × environment (GGE) biplot methodology has the potential to determine combining ability effects, identify efficient testers, and distinct heterotic groups in a line × tester study. However, it has not been adequately applied for such analysis. Therefore, this study was done to assess the combining ability of some maize inbr

5. Knowledge gaps regarding frugivorous ecological networks between birds and plants in Brazil
Abstract Vegetation stability, resilience and regeneration can be achieved by various ecological processes, the most important of which is seed dispersion. Among animal groups, birds have the largest number of frugivorous species in the Neotropics. The aim of this study was to conduct a bibliometric analysis to detect general patterns and discover knowledge

6. Sequence stratigraphy of fluvial to shallow-marine deposits: The case of the early Permian Rio Bonito Formation, Paraná Basin, southernmost Brazil
Abstract This study presents new sedimentology data and attempts to understand coastal processes, sedimentary dynamics and stratigraphic patterns of the Rio Bonito Formation (early Permian) in Paraná Basin, southern Brazil. The study was performed based on the description of five cores, located in a small-scale area - São Gabriel City - in Rio Grande do Su

7. Aproximações entre governança colaborativa e ação comunicativa: uma proposta analítica de estudo
Resumo Pode-se dizer que os esforços do gerencialismo não conseguiram apresentar grandes mudanças nos padrões das relações entre Estado centralizador e sociedade. Com isso em vista, o objetivo desta pesquisa foi propor uma abordagem analítica, a partir das aproximações entre governança colaborativa (GC) e teoria da ação comunicativa (TAC), para i

8. Green synthesis and Characterization of ZnO-CoFe2O4 Semiconductor Photocatalysts Prepared Using Rambutan (Nephelium lappaceum L.) Peel Extract
In this work, the semiconductor of ZnO-CoFe2O4 composites were prepared by green synthesis approach using rambutan peel extract (Nephelium lappaceum L.) as a capping agent. X-ray diffraction patterns of composites showed the main peaks of ZnO at 2θ = 31.8°, 34.5°, and 36.2° corresponding to hexagonal wurtzite structure and weak peak at 2θ = 35.4° for c

9. AGENTES PENITENCIÁRIOS APRISIONADOS EM SUAS REDES?
Neste trabalho, investigamos os componentes das redes pessoais de agentes prisionais e problematizamos se a maior restrição ao ambiente custodial pode ser vista como um efeito do trabalho em penitenciárias. Para tanto, foram utilizadas as entrevistas em profundidade (realizadas entre 2015 e 2017), com presos e agentes da Região Metropolitana de Belo Hori

10. The study of biotic interactions in the Brazilian Cerrado as a path to the conservation of biodiversity
Abstract: As a focus for conservation efforts, biodiversity has received increased attention in the last fifty years. Searching for patterns in biodiversity, researchers have suggested studies including: ecological communities, cladistics classifications, hierarchical compositions of different levels of organization, and groups of taxonomically related speci

11. 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

12. Genetic Population Structure and Allele Surfing During Range Expansion in Dynamic Habitats
Abstract: Expanding populations may loss genetic diversity because sequential founder events throughout a wave of demographic expansion may cause “allele surfing”, as the alleles of founder individuals may propagate rapidly through space. The spatial components of allele surfing have been studied by geneticists, but have never been investigate on dynamic
