Printed bodies and binary publishing segmentation : an analysis of gender relations between the brazilian magazines TRIP and TPM.
Uma vis?o superficial e limitada sobre as identidades de g?nero, muito comum em diversas publica??es do mercado editorial brasileiro, ? algo que, historicamente, as revistas TRIP e TPM buscam (e afirmam) combater. Diante desse contexto, este artigo estuda edi??es destas publica??es, tendo como recorte aquelas cuja tem?tica rec?proca aborda o corpo humano. A partir de uma an?lise das estruturas das revistas, editoriais, reportagens e imagens que se conectam com o foco tem?tico de cada edi??o das publica??es, observa-se tens?es e intera??es entre os respectivos projetos editoriais a partir das rela??es de g?nero ali manifestas. Percebese, ao final, que um papel normatizador sobressai das narrativas, como regulador de sentidos e da manuten??o de uma l?gica bin?ria nas coberturas jornal?sticas realizadas.A superficial and limited view of gender identities, widely used in several publications in the Brazilian publishing market, is something historically that TRIP and TPM magazines are trying (and claim) to combat. Given this context, this article studies editions of these publications, having as a emprical data those whose reciprocal theme addresses the human body. From an analysis of the structures of magazines, editorials, reports and images that connect with the thematic focus of each edition of the publications, tensions and interactions between the respective editorial projects are observed from the gender relations manifested there. It can be seen that a normative role stands out from the narratives, as a regulator of meanings and the maintenance of a binary logic in the journalistic coverage performed
Antileishmanial activity of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae).
This study aimed to evaluate the leishmanicidal activity of ethanol extract, fractions, and isolated substance from Handroanthus
serratifolius against Leishmania amazonensis. Furthermore, this activity was related to cytotoxicity, and the selectivity index was
determined.The ethanol extract was obtained by maceration of the stem powder, and the extract was subjected to fractionation on
chromatographic column. The lapachol was obtained by acid base extraction followed by purification in chromatographic column.
The antipromastigote activity and cytotoxicity tests were carried out by the cell viabilitymethod (MTT).Modified THP-1 cells were
infected with L. amazonensis promastigotes and treated for 24 h with different concentrations of the extract, fractions, and lapachol.
Theethanol extract, dichloromethane, and ethyl acetate fractions were not active against promastigotes (IC50 > 200 ?g/mL) or cytotoxic
(CC50 > 500 ?g/mL), and the selectivity index (SI)was greater than 2.5.The ethyl acetate fractionwas active only in promastigotes;
it is not cytotoxic (CC50 > 500 ?g/mL, SI > 5).The lapachol was selectively active only against amastigote (IS > 2.5, CC50 >
500 ?g/mL). In summary, lapachol and ethyl acetate fraction are promising against amastigote and promastigote forms, respectively
Effect of warm rolling on the corrosion and mechanical properties of UNS S32205 Duplex stainless steel.
Duplex stainless steel (DSS) has been considered as an excellent alternative for applications where high corrosion resistance and high mechanical strength are required. Therefore, microstructure and properties of DSS remain topics of much interest. For this purpose, the effect of warm-rolling was studied in a duplex stainless steel. The focus of this work was 2205 which is one of the most useful type of DSS. Although evolution of microstructure, texture and tensile properties during warm rolling of DDS have been reported, there is no study on the effect of warm rolling on corrosion resistance of 2205 DSS. In this context, the objective of this work is to evaluate microstructure, texture and mechanical and corrosion properties of UNS S32205 DSS after warm rolling. The duplex stainless steel was warm-rolled at 600?C up to 60 and 80% thickness reduction and submitted to electrochemical tests. The electrochemical behaviour of warm-rolled 2205 in the chlorine ion environment was evaluated using cyclic potentiodynamic polarization (CPP) and electrochemical impedance spectroscopy (EIS). The samples exhibited an excellent corrosion resistance in 3.5% NaCl solution. The study showed that the thermomechanical treatment used favoured the formation of the passive film and led to a greater polarization resistance. This behaviour is consistent with the pits density observed by scanning electron microscopy (SEM) and the crystallographic microtexture of the steel
Iron Status and Analysis of Efficacy and Safety of Ferric Carboxymaltose Treatment in Patients with Inflammatory Bowel Disease
Background and Aims:We analyzed iron deficiency and the therapeutic response following intravenous ferric carboxymaltose in a large single-center inflammatory bowel disease (IBD) cohort. Methods: 250 IBD patients were retrospectively analyzed for iron deficiency and iron deficiency anemia. A subgroup was analyzed regarding efficacy and side effects of iron supplementation with ferric carboxymaltose. Results: In the cohort (n = 250), 54.4% of the patients had serum iron levels 60 mu g/dl, 61.6% had ferritin >100 ng/ml, and 90.7% reached Hb >12/13 g/dl at follow-up (p < 0.0001 for all parameters vs. pretreatment values). The most frequent adverse event was a transient increase of liver enzymes with male gender as risk factor (p = 0.008, OR 8.62, 95% CI 1.74-41.66). Conclusions: Iron deficiency and anemia are frequent in IBD patients. Treatment with ferric carboxymaltose is efficious, safe and well tolerated in iron-deficient IBD patients. Copyright (C) 2011 S.

High resolution mass spectrometry elucidation of captopril?s ozonation and chlorination by-products.
The article evaluated the degradation of the captopril in aqueous solution after
ozonation and chlorination. The process was continuously monitored focusing
on the identification, mass spectrometry and elucidation of its by-products
by applying direct infusion and high performance liquid chromatography,
electrospray ionization high resolution mass spectrometry, in the negative
ion mode. The cytotoxicity of its by-products solutions were evaluated
with 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT)
assay. It was observed through that after 30 min of ozonation and chlorination,
there was complete oxidation of captopril, i .e ., 100% removal efficiency.
At these conditions, the rate of mineralization, by total organic carbon, was
only 7.63% for ozonation and 6.40% for chlorination, evidencing the formation
of degradation by-products. Ten captopril by-products were identified
and their respective chemical structures elucidations are proposed. The treated
samples and their by-products were nontoxic to HepG2 cells by MTT assay
Performance of the LHCb vertex locator
The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in the LHCb experiment. The performance of the detector during the first years of its physics operation is reviewed. The system is operated in vacuum, uses a bi-phase CO2 cooling system, and the sensors are moved to 7 mm from the LHC beam for physics data taking. The performance and stability of these characteristic features of the detector are described, and details of the material budget are given. The calibration of the timing and the data processing algorithms that are implemented in FPGAs are described. The system performance is fully characterised. The sensors have a signal to noise ratio of approximately 20 and a best hit resolution of 4 ÎŒm is achieved at the optimal track angle. The typical detector occupancy for minimum bias events in standard operating conditions in 2011 is around 0.5%, and the detector has less than 1% of faulty strips. The proximity of the detector to the beam means that the inner regions of the n+-on-n sensors have undergone space-charge sign inversion due to radiation damage. The VELO performance parameters that drive the experiment's physics sensitivity are also given. The track finding efficiency of the VELO is typically above 98% and the modules have been aligned to a precision of 1 ÎŒm for translations in the plane transverse to the beam. A primary vertex resolution of 13 ÎŒm in the transverse plane and 71 ÎŒm along the beam axis is achieved for vertices with 25 tracks. An impact parameter resolution of less than 35 ÎŒm is achieved for particles with transverse momentum greater than 1 GeV/c
Precision luminosity measurements at LHCb
Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy âs. In this paper results are reported from the luminosity calibrations carried out at the LHC interaction point 8 with the LHCb detector for âs = 2.76, 7 and 8 TeV (proton-proton collisions) and for âsNN = 5 TeV (proton-lead collisions). Both the "van der Meer scan" and "beam-gas imaging" luminosity calibration methods were employed. It is observed that the beam density profile cannot always be described by a function that is factorizable in the two transverse coordinates. The introduction of a two-dimensional description of the beams improves significantly the consistency of the results. For proton-proton interactions at âs = 8 TeV a relative precision of the luminosity calibration of 1.47% is obtained using van der Meer scans and 1.43% using beam-gas imaging, resulting in a combined precision of 1.12%. Applying the calibration to the full data set determines the luminosity with a precision of 1.16%. This represents the most precise luminosity measurement achieved so far at a bunched-beam hadron collider
Communication in production animal medicine: modelling a complex interaction with the example of dairy herd health medicine
<p>Abstract</p> <p>Background</p> <p>The importance of communication skills in veterinary medicine is increasingly recognised. Appropriate communication skills towards the client are of utmost importance in both companion animal practice and production animal field and consultancy work. The need for building a relationship with the client, alongside developing a structure for the consultation is widely recognised and applies to both types of veterinary practice.</p> <p>Results</p> <p>Veterinary advisory practice in production animal medicine is, however, characterised by a more complex communication on different levels. While the person-orientated communication is a permanent process between veterinarian and client with a rather personal perspective and defines the roles of interaction, the problem-orientated communication deals with emerging difficulties; the objective is to solve an acute health problem. The solution - orientated communication is a form of communication in which both veterinarian and client address longstanding situations or problems with the objective to improve herd health and subsequently productivity performance. All three forms of communication overlap.</p> <p>Conclusions</p> <p>Based on this model, it appears useful for a veterinary practice to offer both a curative and an advisory service, but to keep these two separated when deemed appropriate. In veterinary education, the strategies and techniques necessary for solution orientated communication should be included in the teaching of communication skills.</p
Cloxacillin nanostructured formulation for the treatment of bovine keratoconjunctivitis.
Infectious bovine keratoconjunctivitis (IBK) is a widespread, contagious ocular disease that affects cattle, especially dairy breeds. The disease is caused by Gram-negative bacteria mainly Moraxella bovis, and its treatment consists of parenteral or topic antibiotic therapy. The topic treatment approach is used more commonly in lactating cows, to avoid milk disposal. However, treatment failures are common, because the antibiotic is removed during lacrimation. This study aimed to evaluate the susceptibility of commercial cloxacillin and evaluate the efficacy of nanostructured cloxacillin in clinical cases of IBK by Moraxella. The minimum inhibitory concentration (MIC) of nanoparticle cloxacillin nanocoated, the nanoparticle without the antibiotic and the commercial cloxacillin were determined in vitro with field samples of Moraxella ovis (5) and Moraxella bovis (5). The efficiency of nanoparticles was tested in three cows naturally infected that were treated with 1.0 mL (with 0.32 mg of nanostructured cloxacillin) for the ocular route. Moraxella bovis was isolated and identified by biochemical and molecular methods before the treatment. The animals were treated every 12 h for six days. The cure was considered by the absence of clinical symptoms and bacteria after treatment. The mucoadhesive nanoparticle-based formulation promoted clinical cure with a low number of doses of antibiotics, probably due to the maintenance of the MIC in the ocular mucosa for longer due to the mucoadhesive characteristics of the nanoparticle. The results indicate that the use of nanocoated cloxacillin is possible to control infectious bovine keratoconjunctivitis
