1. Petiveria alliacea, a plant used in Afro-Brazilian smoke rituals, triggers pulmonary inflammation in rats
Abstract Petiveria alliacea L., Phytolaccaceae, a plant used in Afro-Brazilian religious smoke rituals is reported to have "harmonic properties" (anxiolytic effect) by ethnobotanical survey. In the present work, we analyzed the chemical composition of volatiles produced by leaves of P. alliacea, using headspace gas chromatography/mass spectrometry and its po

2. Rhinoxenus (Dactylogyridae) parasitizing piranhas (Serrasalmidae) at its southernmost limit of distribution (Paraná River, Argentina), with the description of two new species
Abstract Abstract: Three piranha species, Serrasalmus maculatus, S. marginatus and Pygocentrus nattereri, living sympatrically in the lower Paraná River (Argentina) were examined searching for nasal monogeneans to know its diversity and distribution. Four species of monogeneans belonging to Rhinoxenus were found parasitizing the nasal cavities. Two new spec

3. Morphological and genetic perspectives of hybridization in two contact zones of closely related species of Petunia (Solanaceae) in southern Brazil
ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses

4. Effect of stem cells combined with a polymer/ceramic membrane on osteoporotic bone repair
Abstract Cell therapy associated with guided bone regeneration (GBR) can be used to treat bone defects under challenging conditions such as osteoporosis. This study aimed to evaluate the effect of mesenchymal stem cells (MSCs) in combination with a poly(vinylidene-trifluoroethylene)/barium titanate (PVDF-TrFE/BT) membrane on bone repair in osteoporotic rats.

5. DOES THE RHEUMATOID ARTHRITIS AFFECT THE ENTERIC NERVOUS SYSTEM?
RESUMO CONTEXTO: Poucos estudos sobre doenças artríticas têm sido realizados para verificar a presença de neurodegeneração. Diante do aumento do estresse oxidativo e dos efeitos extra-articulares da artrite reumatoide, estudos gastrointestinais devem ser investigados visando uma melhor compreensão dos efeitos sistêmicos da doença no sistema nervos

6. Trypanorhynch cestodes parasitizing Mugil liza (Mugiliformes: Mugilidae) commercialized in the state of Rio de Janeiro, Brazil
Resumo O presente estudo objetivou determinar taxonomicamente as espécies de plerocercos de cestoides Trypanorhyncha encontradas na serosa intestinal das tainhas Mugil liza, através do estudo morfológico e morfométrico e indicar seus índices parasitários. Foram coletados 150 espécimes desta espécie de tainha do litoral do estado do Rio de Janeiro. Ap

7. Acanthocephalan parasites of the flounder species Paralichthys isosceles, Paralichthys patagonicus and Xystreurys rasile from Brazil
Resumo Os linguados são peixes comercial e economicamente importantes. Um total de 120 espécimes de linguados (60 Paralichthys isosceles, 30 P. patagonicus e 30 Xystreurys rasile) foram coletados no litoral do estado do Rio de Janeiro, Brasil. Os peixes foram medidos, necropsiados, filetados e tiveram seus órgãos investigados para a presença de acantoc�

8. Morphometric analysis in the shells of the planktonic foraminifera Orbulina universa: a source for paleoceanographic information?
Abstract In this study, we describe morphometric analyses of Orbulina universa morphotypes presently found in the Western South Atlantic, and their relation to the upper water thermohaline indexes. We also investigate this relationship under glacial and interglacial conditions between 7.2 and 32 kyr BP. Ten plankton samples distributed between 32º55' and 26

10. Geographic variation of Moenkhausia bonita (Characiformes: Characidae) in the rio de la Plata basin, with distributional comments on M. intermedia
ABSTRACT Moenkhausia bonita occurs in numerous additional localities from the Bermejo, Paraná, Paraguay, and Uruguay river basins. Given that this finding greatly expands the distributional range of M. bonita, we carried out an intraspecific comparison, using multivariate methods for 18 morphometric and eight meristic characters taken from a comprehensive s

11. Multinomial Logistic Regression and Random Forest Classifiers in Digital Mapping of Soil Classes in Western Haiti
ABSTRACT Digital soil mapping (DSM) has been increasingly used to provide quick and accurate spatial information to support decision-makers in agricultural and environmental planning programs. In this study, we used a DSM approach to map soils in western Haiti and compare the performance of the Multinomial Logistic Regression (MLR) with Random Forest (RF) to

12. Biometrical and morphological analyses of Macrobrachium olfersii (Wiegmann, 1836) (Crustacea, Decapoda, Palaemonidae) embryos exposed to UVA and UVB radiation
ABSTRACT Macrobrachium olfersii (Wiegmann, 1836) is a prawn that lives in shallow and transparent freshwater in Southern Brazil. Aquatic organisms that inhabit these systems can be exposed to incident UV radiation. Many studies have demonstrated the effects of ultraviolet (UV) radiation on the development, survival rate, morphological abnormalities, and impa
