title: Diversity of Biomphalaria spp. freshwater snails and associated mollusks in areas with schistosomiasis risk, using molecular and spatial analysis tools

description: Abstract: The Middle Paranapanema River region of São Paulo, Brazil is home to significant diversity of Biomphalaria species and is very vulnerable to health and environmental impacts such as schistosomiasis. This study updates freshwater malacological surveys for ecosystems in one portion of the Middle Paranapanema River Basin, with emphasis on the genus Biomphalaria. Snails were collected from 114 distinct bodies of water between 2015 and 2018. Biomphalaria specimens were identified according to morphological and molecular characteristics, while animals in other genera (Drepanotrema, Lymnaea, Melanoides, Physa and Pomacea) were identified solely according to shell characteristics. A geographic information system was used to update intermediate host colonization sites and consequently assist in identifying probable hotspots for intermediate hosts of schistosomiasis. The sequences of the COI gene relating to the DNA barcode stretch were tested for similarity against sequences found in GenBank, for monophyly through Maximum Likelihood phylogenetic inference, and analyzed in ABDG, bPTP and GMYC for the delimitation of putative species. Of the 10,722 snails collected, 86.7% were in the Planorbidae family (75.5% Biomphalaria and 11.2% Drepanotrema) and 13.3% were other non-Planorbidae species (Lymnaea, Melanoides, Physa and Pomacea). The taxonomic COI reference sequences in the NCBI nucleotide database used for DNA sequence comparison, and phylogenetic analysis used to test the monophyly of the groups, resulted in more reliable taxonomic units than delimitation of the COI sequences in MOTUs using statistical taxonomic models. Analysis of the species distribution shows that B. glabrata and B. tenagophila are heterogeneously distributed in the study area. B. glabrata colonizes only five water bodies, in the study area, most of them in Ourinhos, while B. tenagophila predominates in water bodies in Ipaussu. Contrasting with this, B. straminea, B. occidentalis and B. peregrina are evenly distributed throughout the study area.

title: Microstructural Adjustments and Tensile Properties of a Hot-Forged Ti−22Al−23Nb−3V−Y Alloy

description: Microstructures and tensile properties of a hot forged Ti−22Al−23Nb−3V−Y alloy were investigated systematically. Different heat treatments were performed to adjust the wrought microstructure to optimize tensile properties. It was found that features of O phase precipitates and its volume fraction was rather sensitive to the cooling rate after the solution. The volume fraction of primary lamellar O phase increased from 19.65% by solution treatment to 36.30% by annealing with furnace cooling and up to 100% by annealing with a controlled slow cooling rate of 1 ºC/min. Meanwhile, the width of the lamellar secondary O phase increased. Fine acicular second O phase contributed to strengthening, while the coarsen primary ones were favorable to the ductility. The solution & aging treated microstructure exhibited a good tensile strength of 1100 MPa and an acceptable ductility of 8% at room temperature, by contrast, annealing at 950 ºC with a controlled slow cooling rate gave rise to a higher elongation of 12%, but a relatively low strength of 960 MPa.

title: Relationship between erythrocyte sedimentation rate and choroidal and retinal thickness in Behçet's disease

description: ABSTRACT Purpose: To compare retinal and choroidal thickness in patients with Behçet's disease with and without ocular involvement as well as to evaluate the correlation between erythrocyte sedimentation rate and choroidal thickness among patients with Behçet's disease. Methods: This was a prospective interventional study investigating erythrocyte sedimentation as well as choroidal and retinal thickness among patients with Behçet's disease. Patients who were diagnosed based on The International Criteria for Behçet's Disease with (Group A) or without (Group B) ocular involvement and a matched control group (Group C) participated in the study. Optical coherence tomography measurements and blood tests were performed on the same day. Retinal and choroidal thickness were measured using spectral-domain optical coherence tomography (Spectralis, Heidelberg Engineering, Heidelberg, Germany), and central macular thickness, central subfoveal choroidal thickness, and retinal nerve fiber layer thickness were measured using optical coherence tomography. Results: Average erythrocyte sedimentation values were 9.89 mm/h in Group A, 16.21 mm/h in Group B, and 3.89 mm/h in Group C; average central subfoveal choroidal thickness values were 350.66, 331.74, and 325.95 mm, respectively. Average central macular thickness and retinal nerve fiber layer thickness values of patients in Groups A, B and C were 226.39 and 225.97mm; 234.11 and 92.00 mm; and 97.58 and 99.84 mm, respectively. No significant difference was seen between Group A and B patients in central subfoveal choroidal thickness, central macular thickness, or retinal nerve fiber layer thickness values. Central macular thickness was statistically significantly thinner in Groups A and B than in Group C (p=0.016). Group A had thinning in the nasal quadrant of the retinal and general retinal nerve fiber layers when compared with those in Group C (p=0.010 and 0.041, respectively). A connection could not be established between the erythrocyte sedimentation, central subfoveal choroidal thickness, central macular thickness, and retinal nerve fiber layer thickness in the patients with Behçet's disease. Conclusion: The erythrocyte sedimentation rate is typically used to test for activation of Behçet's disease and assess treatment response. In our study, we could not establish a connection between the erythrocyte sedimentation rate and central subfoveal choroidal thickness, central macular thickness, and retinal nerve fiber layer thickness in patients with systematically active Behçet's disease without ocular involvement.

title: Violence against indigenous children and adolescents in Venezuela

description: Abstract: Research on violence in indigenous communities refers to traditional practices of competition for scarce goods and clashes with other populations over their territories. Violence against children is not described, and authors of some studies state a tradition of good treatment towards them. In our study we shows that the situation has changed and new forms of violence are affecting 725,000 inhabitants from 51 indigenous groups of Venezuela, especially those composed of children and adolescents. The method used was interviews with key informants and for secondary census, civil society data and journalists’ reports. Results describe the existence of four types of violence: (a) structural violence, derived from the shortage of food and medicines that have caused deaths due to malnutrition and lack of medical attention, prostitution, girl trafficking and forced emigration; (b) violence of organized crime, which exercise control of illegal mining and affect the Yanomami and Pemón peoples, as workforce for the production of coca and drug trafficking with the Yupka people; and contraband of gasoline in the Wayúu people; (c) domestic violence due to cultural changes derived from new patterns of alcohol consumption or the use of physical punishment of children between Piaroa and Yekuana peoples; and (d) the illegal violence of the State for the imposition of mining with the Pemón people or the repression for the protests with the Warao and Inga peoples. In the article we show the great difference between the official discourse of protection of indigenous peoples and the realities of violence, criminal exploitation and violation of rights suffered by indigenous children and adolescents.

title: Quantitative evaluation of brain volume among elderly individuals in São Paulo, Brazil: a population-based study

description: Abstract Objective: To perform a quantitative analysis of the brain volume of elderly individuals in a population-based sample. Materials and Methods: This was a radiological assessment and voxel-based quantitative analysis, with surface alignment, of 525 magnetic resonance imaging scans of individuals between 60 and 103 years of age who participated in the Saúde, Bem-estar e Envelhecimento (Health, Well-being, and Aging) study in the city of São Paulo, Brazil. Results: We noted a median rate of reduction in total brain volume of 2.4% per decade after 60 years of age. Gray and white matter both showed volume reductions with age. The total brain volume/intracranial brain volume ratio differed between males and females. Conclusion: We have corroborated the findings of studies conducted in the United States and Europe. The total brain volume/intracranial brain volume ratio is higher in men, representing a potential bias for the conventional radiological assessment of atrophy, which is typically based on the evaluation of the cerebrospinal fluid spaces.

title: Sustainable productive intensification for family farming in developing tropical countries

description: ABSTRACT In the past, agriculture was directed to satisfying human needs. Nowadays, it is directed to meeting the markets, forcing the peasantries to adapt to this condition. As a result, family farmers are multifaceted, incorporating both subsistence and market-oriented production. Traditional farming systems have been challenged since there is a pressure for the intensification of these systems. Then, it is important that scientific research about them goes on to recognize that many family farmers use limited resource bases. However, innovation and intensification are permanent needs of agriculture, although they must be adjusted to different contexts, respecting the cultural legacy of family farmers as a prerequisite for achieving the development.

title: Ex situ initial seedling development of Hymenaea courbaril L. (Fabaceae): a crucial phase to preserve the species

description: ABSTRACT Hymenaea courbaril L. is an important Neotropical species, with low population density, restricted to fragments of semideciduous forests, with low mortality and low recruitment. Thus, some questions guided the goals of this paper including the capacity of stored seeds to form normal seedlings. Seeds collected from ten mother plants in the Brazilian Cerrado region and stored during three years were mechanically scarified, sown and analyzed during 43 days. Intraspecific variability was observed for water content, seed biometry, and emergence process. The seedling emergence varied from 19 to 92%. Nine phases of development were observed. About 91% of the seedlings reached their complete autotrophy and this represents the success of the sample; the rest of the seedlings presented atypical morphology. This means that it is possible to store the seeds with the purpose of obtaining seedlings for ex situ cultivation. The great consumption of the cotyledon reserves occurred in the period that marks the alignment of cotyledons with hypocotyls (phases 1 to 4). For this species, if the seeds are scarified, the first 40 days after sowing are essential for the seedling establishment. After this time, the cotyledons fall signing a good point of reference for restoration projects because it indicates that the young plant is autonomous.

title: Levamisole on the biochemical and hematological responses to parasitism by monogenoids in dog snapper

description: ABSTRACT: The response of biochemical and hematological parameters were analyzed in dog snapper (Lutjanus jocu) grown in net cages, as well as for the specimens kept in the laboratory during an infestation by Neobenedenia melleni, and after treatment with freshwater bath and injectable application of levamisole. Significant changes were observed in N. melleni parasitized individuals, characterized by increased glucose and lactate levels, as well as a significant fish hematocrit reduction and leukocyte increase. Treatment with freshwater baths, concomitant with injectable levamisole application, showed therapeutic efficacy in several parameters after 14 days of treatment.

title: Influence of the Solution-Treatment Temperature and Short Aging Times on The Electrochemical Corrosion Behaviour of Uns S32520 Super Duplex Stainless Steel

description: Sigma phase leads to deterioration of corrosion resistance of super duplex stainless steels (SDSS) and its volume fraction increases as the time which the materials is exposed in determined temperature increases. In the present study, the effect of the short aging time on the formation of the sigma phase and on the corrosion behavior of UNS S32520 SDSS at 3.5% sodium chloride solution was evaluated using microstructural characterization, linear potentiodynamic polarization curve and electrochemical impedance spectroscopy. The results indicated that the SDSS sample solution-treated at 1150ºC and aged at 850ºC for 5 min may improve the corrosion resistance in comparison with the as-received and solution-treated conditions, due to the better partition of the elements Cr, Mo and dissolution of certain amount of sigma phase in the microstructure. However, results also showed that when SDSS solution-treated at 1150ºC is aged at 850ºC with the aging time slightly superior (10 min), the precipitation of sigma phase increases leading to a rapid deterioration of the corrosion resistance of the material.

title: Glycerol Effect on the Corrosion Resistance and Electrodeposition Conditions in a Zinc Electroplating Process

description: Zinc electrodeposition is an economical process of Zn coating compared to conventional galvanic process. The galvanizing process is used in various industrial sectors to protect ferrous alloys during the corrosion process. In buildings, the galvanizing process is widely used to coat mortar protective screens. The electrodeposition of zinc has a relatively low cost compared to other coating materials for the same purpose; however, its corrosion resistance is lower than that of most protective deposits. This study evaluated the effect of adding glycerol to the electrodeposition bath on the corrosion resistance, deposition efficiency, morphology and microstructure of the zinc electrodeposit in concentrations ranging from 0.03 to 0.82 M. The electrodeposition was performed on carbon steel AISI 1020 with a current density of 10 mA.cm-2. The electroplating solution composition was 0.10 M ZnCl2, 2.80 M KCl and 0.32 M H3BO3. Electrodeposition time was 17.56 min, 5 µm thick coating, equivalent to the mass of 7.166E-3 g of zinc on the steel surface. Evaluation of the corrosion resistance was performed by means of the electrochemical tests of Anodic Voltammetry, Potentiodynamic Polarization and Electrochemical Impedance Spectroscopy (EIS) as well as Weight Loss tests in NaCl 0.5 M in 4 (four) different period of immersion. The morphology and microstructures of electrodeposited were analyzed using the techniques of Scanning Electron Microscopy (SEM) and Spectrometry X-Ray Diffraction (XRD). The presence of glycerol in the electrodeposition bath decreased the deposition efficiency; however, it increased corrosion resistance and promoted the formation of more compact and refined electrodeposited coatings. Moreover, the results showed that the corrosion rate does not vary linearly with the addition of glycerol.

title: Minimally Invasive Cardiac Surgery versus Sternotomy - Pain Investigation

description: Abstract Background: Treatment of postoperative (PO) pain is essential after surgery, as it contributes to a faster rehabilitation. Assessment of PO pain after minimally invasive (MI) surgery has not been regularly addressed, especially when compared with median sternotomy (MS). Objective: This study aims to evaluate the intensity of thoracic pain in the PO period in patients subjected to MI surgery and MS. Methods: This study compared the intensity of thoracic pain in 34 patients subjected to minimally invasive (MI; n = 17) and median sternotomy (MS; n = 17) from June 2015 to June 2016. The intensity and sites of pain in the PO period, assessed using the visual numeric pain scale, and the need for pain medications were analyzed using the Student’s t-test and the z test, with confidence level of 95% (p &lt; 0.05). Results: Almost all patients reported pain on the third PO day (MS = 94.1% and MI = 88.2%; p = 0.5410). On the seventh PO day, there were significantly more patients free of pain in the group of patients subjected to the MI procedure (MS = 94.1% and MI = 64.7%; p = 0.0341). also, these patients reported fewer pain sites (3rd PO day: MS = 3.2 ± 1.5; MI = 1.5 ± 1.2; p = 0.001; 7th PO day: MS = 3.1 ± 1.4; MI = 0.9 ± 0.9; p = 0.000). Patients undergoing MS reported higher pain intensity and longer lasting pain (3rd PO: MS = 4.8 ± 2.2; MI = 3.0 ± 1.6; 7th PO: MS = 5.3 ± 2.0; MI = 1.2 ± 1.3; p = 0.001), with no difference in pain intensity between the third and the seventh PO days (p = 0.4931). In addition, patients subjected to MI procedure had a significant decrease in pain intensity from the third to the seventh PO days (p = 0.001). Conclusion: According to these results, we concluded that a MI procedure leads to lower intensity of pain in the PO period (from the third PO day on) when compared to a MS; also, patients undergoing MI patients reported fewer pain sites.
