Contribution to the knowledge of Podischnus Burmeister, 1847 (Coleoptera, Melolonthidae: Dynastinae) with the description of two new species from Brazilian Amazon Forest

Two new Podischnus Burmeister, 1847 species are described here: Podischnus limeirai sp. nov. from Gurupi region, Maranhão state, Brazil, the easternmost distribution of the genus; and Podischnus cleidecostae sp. nov. from the Acre state, Western of Brazilian Amazon Forest. New diagnostic characters are illustrated and discussed for the genus. An illustrated identification key for all Podischnus species, and an up-to-date distribution map for the Brazilian species of Podischnus are provided. Moreover, we propose the inclusion of P. limeirai sp. nov. in the Red List of Threatened Species (IUCN) due to the fast loss of the Oriental Amazon Forest remnant fragment in that region

AS VEIAS ABERTAS DO TERRORISMO NA AMÉRICA LATINA : Percepções sobre o uso dos “direitos humanos” no vilipêndio aos Direitos Humanos – Chile, Brasil e Argentina.

O presente trabalho logra analisar de que forma o discurso encantador de proteção aos direitos humanos é deturpado e manipulado para vilipendiação desses mesmos Direitos. Demonstrará a política terrorista adotada pelos Estados Unidos da América como forma de combate a atos (por eles classificados) como terroristas. Estabelece como contraponto os regimes militares instaurados no Chile, Brasil e Argentina que, de forma direta ou indireta, guardaram relação estreita com o governo estadunidense. A denuncia da mídia logra evidenciar de que forma a deturpação e apropriação instrumentalizada de informações são artifícios de uso hodierno para camuflar a conquista por espaços do Outro latinoamericano. Analisa ainda como a totalidade europeia e norte-americana oprime a emancipação da América Latina e de que forma o reconhecimento, a memória, a verdade do povo ameríndio é vital para que essas políticas terroristas de “proteção” aos direitos humanos seja afastada, e o vilipendio a esses direitos igualmente combatidos

Pensando sobre o Uso das Tecnologias na Formação de Professores no Contexto EaD

This article presents the result of a research that aims to reveal if, and how, teacher’s education in the Distance Learning Context appropriate the use of digital technologies.  The research is qualitative in nature and the data was collected through electronic questionnaires. The subjects are 22 teacher’s education of mathematics, graduated in distance learning context at a State University of Paraná. The data were organized and analyzed by means of Discursive Textual Analysis and Cluster Analysis from where we were able to identify two main clusters. Nossos resultados apontam há indícios de incorporação do uso das tecnologias digitais na prática docente dos egressos do cluster 1. We believe that this has been evidenced mainly because these egresses began the degree course with the desire to be a teacher and for exercising the teaching profession, unlike the subjects of Cluster 2.   Keywords: Teacher education of mathematic.

Depressão vascular no idoso: resposta ao tratamento antidepressivo associado a inibidor das colinesterases

CONTEXT: Among neuropsychiatric disorders caused by cerebrovascular factors, vascular depression is diagnosed in a small degree by general practitioners, causing morbid-mortality increase in elderly. CASE REPORT: That is a case of a 67 year-old-man with partial response after treatment with a Selective Serotonin Receptors Inhibitor, and severe autonomic adverse effects with other antidepressants. The addition of rivastigmine to citalopram resulted in a therapeutic success, with a reduction of 23 to 7 points on the Hamilton Depressive Scale (HAM-D). DISCUSSION: The result obtained brings new perspectives to the treatment of vascular depression, providing that randomized controlled trials with larger sample sizes confirm the positive effect of the addition of a cholinesterase inhibitor to antidepressants in the treatment of these patients.CONTEXTO: Entre os transtornos neuropsiquiátricos ocasionados por eventos cerebrovasculares, a depressão vascular é pouco diagnosticada por médicos não especialistas, causando aumento da morbimortalidade de pacientes idosos. CASO CLÍNICO: Trata-se de um paciente com 67 anos que apresentou resposta parcial a tratamento com inibidores da recaptura de serotonina e efeitos adversos autonômicos graves com outros antidepressivos. A adição de rivastigmina ao citalopram promoveu sucesso terapêutico, com redução de 23 para 7 pontos, na escala de Hamilton para depressão. DISCUSSÃO: O resultado obtido traz novas perspectivas para o tratamento da depressão vascular, sendo necessários ensaios clínicos controlados que evidenciem o benefício da adição dos inibidores das colinesterases aos antidepressivos no tratamento destes pacientes

Effects of a local single dose administration of growth hormone on the osseointegration of titanium implants

The aim of the present study was to evaluate the effect of different concentrations of growth hormone (GH) on endosteal implant?s surface at the early stages of osseointegration. Sixty tapered acid-etched titanium implants were divided into four groups: i) Collagen, used as a control group; and three experimental groups, where after collagen coating, GH was administered directly to the surface in varying concentrations: ii) 0.265 mg, iii) 0.53 mg, and iv) 1 mg. Implants were placed in an interpolated fashion in the anterior flange of C3, C4 or C5 of 15 sheep with minimum distance of 6 mm between implants. After 3-, 6- and 12-weeks of healing samples were harvested, histologically processed, qualitatively and quantitatively assessed for bone-to-implant contact (BIC) and bone area fraction occupancy (BAFO). Statistical analysis as a function of time in vivo and coating resulted in no significant differences for BIC and BAFO at any evaluation time point. Histological evaluation demonstrated similar osseointegration features for all groups with woven bone formation at 3 weeks and progressive replacement of woven for lamellar bone in close contact with the implant surface and within the implant?s threads. A single local application of growth hormone to the surface of titanium implants did not yield improved implant osseointegration independent of healing time

The plant WEE1 kinase is involved in checkpoint control activation in nematode-induced galls

Galls induced by plant‐parasitic nematodes involve a hyperactivation of the plant mitotic and endocycle machinery for their profit. Dedifferentiation of host root cells includes drastic cellular and molecular readjustments. In such background, potential DNA damage in the genome of gall cells is eminent. We questioned if DNA damage checkpoints activation followed by DNA repair occurred, or was eventually circumvented, in nematode‐induced galls. Galls display transcriptional activation of the DNA damage checkpoint kinase WEE1, correlated with its protein localization in the nuclei. The promoter of the stress marker gene SMR7 was evaluated under the WEE1‐knockout background. Drugs inducing DNA damage and a marker for DNA repair, PARP1 were used to understand mechanisms that might cope with DNA damage in galls. Our functional study revealed that gall cells lacking WEE1 conceivably entered mitosis prematurely disturbing the cell cycle despite the loss of genome integrity. The disrupted nuclei phenotype in giant cells hinted to the accumulation of mitotic defects. As well, WEE1‐knockout in Arabidopsis and downregulation in tomato repressed infection and reproduction of root‐knot nematodes. Together with data on DNA damaging drugs, we suggest a conserved function for WEE1 controlling a G1/S cell cycle arrest in response to replication defect in galls

Galaxy evolution in compact groups I: Revealing a transitional galaxy population through a multiwavelength approach

Compact groups of galaxies (CGs) show members with morphological disturbances, mainly products of galaxy-galaxy interactions, thus making them ideal systems to study galaxy evolution, in high-density environment. To understand how this environment affects the properties of galaxies, we select a sample of 340 CGs in the Stripe 82 region, for a total of 1083 galaxies, and a sample of 2281 field galaxies as a control sample. By performing a multi-wavelength morphological fitting process using S-PLUS data, we divide our sample into early-type (ETG), late-type (LTG), and transition galaxies using the r-band S\'ersic index and the colour (u-r). We find a bimodal distribution in the plane of the effective radius-S\'ersic index, where a secondary "peculiar" galaxy population of smaller and more compact galaxies is found in CGs, which is not observed in the control sample. This indicates that galaxies are undergoing a morphological transformation in CGs. In addition, we find significant statistical differences in the distribution of specific Star Formation Rate (sSFR) when we compare both environments for LTGs and ETGs. We also find a higher fraction of quenched galaxies and a lower median sSFR in CGs than in the control sample, suggesting the existence of environmental effects favoring the cessation of star formation, regardless of galaxy type. Our results support the notion that CGs promote morphological and physical transformations, highlighting their potential as ideal systems for galaxy pre-processing.Comment: 17 pages, 15 figures.
