1. Modulation of neuropeptide Y levels is impaired in crack withdrawal patients
Abstract Introduction The dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has a key role in drug addiction susceptibility. In addition to the well-known relationship between cortisol and the HPA axis, other molecules are involved with stress response and could modify the HPA activation, such as the neuropeptide Y (NPY), which has anxiolytic

3. The population dynamics of three polyphagous owlet moths (Lepidoptera: Noctuidae) and the influence of meteorological factors and ENSO on them
ABSTRACT The owlet moths (Lepidoptera: Noctuidae) Anicla infecta (Ochsenheimer 1816), Elaphria agrotina (Guenée 1852) and Spodoptera frugiperda (J.E. Smith 1797) occur in the entire American continent. These polyphagous moths have a preference for grasses, and have different biological habits. In this study, the populations of these three species were evalu

6. Midgut cells alteration in gamma-irradiated beetles (Blaps polycresta, Coleoptera: Tenebrionidae)
Resumo Este estudo foi conduzido para examinar o efeito da radiação gama em espécimes biológicos. Assim, nosso conceito é esclarecer que a exposição à dose acumulada de raios gama de 0,2 Gy (0,66 rad / seg. Dose) da fonte Cs137 induz perturbações celulares no epitélio do intestino médio da progênie F1 de Polycresta blaps, afetando a nutrição e

7. Pharmaceutical ethnobotany in the Mahabad (West Azerbaijan) biosphere reserve: ethno-pharmaceutical formulations, nutraceutical uses and quantitative aspects
This study endeavors to overcome the limits of an orally transmitted pharmacopoeia, and tries to utilize the large ethnobotany patrimony of the area to investigate the biological diversity. Thirty-five traditional practitioners from dissimilar ethnic groups including traditional health practitioners (THPs) and indigenous people were interviewed. A total of 3

8. Contact phenomena modeling in biological structures on the example of the implant-bone
Abstract The work presents modeling of interface phenomena in biological structures. Selected ways of numerical modeling of phenomena at the boundary of two materials by means of FEM methods are discussed. The work focuses on phenomena related to biological structures and their mutual interactions. Using an example of an implant-bone system, various techniqu

9. Quantity and quality of soil organic matter as a sustainability index under different land uses in Eastern Amazon
ABSTRACT: Soil organic matter (SOM), which influences chemical, physical and biological soil attributes, is the main form of C found in the soil which can also be used as a soil sustainability index. The aim of this study was to use the quantity and quality of SOM as an indicator to determine the sustainability of different land uses (native vegetation, seco

10. 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

11. Can Sarcophagidae (Diptera) be the most important entomological evidence at a death scene? Microcerella halli as a forensic indicator
Abstract Although a corpse can harbor several species of flies, only a few have been sufficiently studied to be used as forensic indicators. Sarcophagidae are an example of how the forensic use of insects can be impaired by taxonomic and biological data limitation. This manuscript provides the first record of the Neotropical flesh fly Microcerella halli (Eng

12. Soil Quality Evaluation Using the Soil Management Assessment Framework (SMAF) in Brazilian Oxisols with Contrasting Texture
ABSTRACT The Soil Management Assessment Framework (SMAF) was developed in the U.S.A. and has been used as a tool for assessing and quantifying changes in soil quality/health (SQ) induced by land uses and agricultural practices in that region and elsewhere throughout the world. An initial study using SMAF in Brazil was recently published, but additional resea
