Os escorpiões (Arachnida, Scorpiones), especialmente na área urbana, devido à grande densidade demográfica e possibilidade de confronto, representam risco à saúde pública. A espécie Tityus serrulatus é a mais importante, do ponto de vista médico, causando o maior número de acidentes. Objetivou-se levantar dados epidemiológicos e a ocorrência de acidentes escorpiônicos em Belo Horizonte, entre 1990 e 1997. Os dados foram obtidos no Hospital de Pronto Socorro João XXIII. Ocorreram 3265 acidentes, sendo ...

Abstract A simple conductimetric system to determine ammonia concentration using a sensor based on a conductor polymer was developed. The sensitive element to ammonia is a thin polyaniline film deposited by chemical synthesis in an acrylic substrate prepared before hand with two graphite electrodes. The conductance of the polyaniline film decreases when exposed to the ammonia gas and this variation can be related to the ammonia concentration. To determine ammonia in fertilizer samples a system consisting ...

In vitro studies have recommended enamel-etching before luting indirect restorations with self-adhesive resin cement. However, there is no scientific proof that this procedure has any clinical relevance. Thus, the aim of this study was to evaluate the effect of enamel-etching on the marginal quality of indirect composite resin restorations (inlay/onlay) using the self-adhesive cement RelyX Unicem clicker. Forty-two posterior teeth were selected from 25 patients that presented one or two teeth with ...

Abstract Background The functional and s tructural characterisation of enzymes that belong to microbial metabolic pathways is very important for structure-based drug design. The main interest in studying shikimate pathway enzymes involves the fact that they are essential for bacteria but do not occur in humans, making them selective targets for design of drugs that do not directly impact humans. Description The ShiKimate Pathway DataBase (SKPDB) is a relational database applied to the study of shikimate ...

The infection by Neospora caninum in sheep can lead to abortion and the birth of weak and debilitated lambs. The aim of this study was to assess the incidence of natural infection by Neospora caninum and the vertical transmission rate among sheep. A flock of 50 sheep was monitored for serum antibody titres against N. caninum and seroconversion over a period of six months using an indirect ELISA technique. The offspring of the herd was also investigated regarding anti-N. caninum antibodies to determine ...

Purpose: To compare the central corneal thickness (CCT) of patients with systemic sclerosis (SSc) and control subjects. Methods: The study group comprised 37 consecutive patients with SSc, and the control group comprised 23 healthy individuals similar in age and sex. CCT value was measured by ultrasound pachymetry. Results: In the SSc group, the mean CCT in the right eye was 534.9 ± 33.5 μm and 536.9 ± 32.4 μm in the left eye. In the control group, the mean CCT was 533.0 ± 32.9 μm in the right eye and 533. ...

In a recent decision of the Tribunal of Milan three Google executives were convicted for violating data protection law, in connection with the online posting of a video showing a disabled person being bullied and insulted. This paper, after illustrating the facts of the case and the reasoning of the judge, discusses the main issue at stake, namely, the role and responsibilities of providers of platforms for user-created contents with regard to violations of data privacy.

The enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) catalyzes the reaction between shikimate 3-phosphate and phosphoenolpyruvate to form 5-enolpyruvylshikimate 3-phosphate, an intermediate in the shikimate pathway, which leads to the biosynthesis of aromatic amino acids. EPSPS exists in an open conformation in the absence of substrates and/or inhibitors and in a closed conformation when bound to the substrate and/or inhibitor. In the present report, the H/D exchange properties of EPSPS ...

Two novel peptides were isolated from the crude venom of the social wasp Polybia paulista, by using RP-HPLC under a gradient of MeCN from 5 to 60% (v/v) and named Polybine-I and -II. Further purification of these peptides under normal phase chromatography, rendered pure enough preparations to be sequenced by Edman degradation chemistry. However, both peptides did not interact with phenylisothiocyanate reagent, suggesting the existence of a chemically blocked N-terminus. Therefore, the sequences of ...

A novel antimicrobial peptide, anoplin, was purified from the venom of the solitary wasp Anoplius samariensis. The sequence was mostly analyzed by mass spectrometry, which was corroborated by solid-phase synthesis. Anoplin, composed of 10 amino acid residues, Gly-Leu-Leu-Lys-Arg-Ile-Lys-Thr-Leu-Leu-NH2, has a high homology to crabrolin and mastoparan-X, the mast cell degranulating peptides from social wasp venoms, and, therefore, can be predicted to adopt an amphipathic α-helix secondary structure. ...

In this paper, we examine the rise of authoritarian populism in Brazil following the election in 2018 of Jair Messias Bolsonaro to the Presidency and reflect on the consequences of his far-right-wing politics for education. Our focus is broadly on three historical blocs (with five different presidents of the Republic) which make up the policy trajectory of Brazil over the period 1995–2019. We explore the complex cultural political economy surrounding more than a decade of left-wing government by ...

The channel-floodplain relationship is used to understand flooding dynamics in the Pantanal wetland. To understand how different fluvial styles along the Upper Paraguay River (UPR) control the hydrology of the Pantanal wetland, we used a database including 11 gauge stations from the Brazilian National Agency of Waters, Landsat series satellite data, GeoCover images circa 1990 and 2000, the SRTM 90 m digital elevation model (DEM) and 34 acoustic Doppler current profiler (ADCP) sections.

O Paraguai é o rio-tronco do trato de sistemas deposicionais do Pantanal. Com base em dados de sensores remotos e verificação de campo, foi realizado mapeamento geomorfológico da planície do rio Paraguai no trecho entre as confluências dos rios Cuiabá e Miranda, onde foram reconhecidas formas deposicionais atuais e antigas. A análise das associações de formas permitiu estabelecer proposta de evolução geomorfológica para a área, mas os eventos carecem ainda de datação precisa por métodos geocronológicos. ...
