Medidas morfométricas e correlações fenotípicas de tilápia Gift submetidas a seleção individual

O objetivo deste estudo foi avaliar o efeito da seleção individual para peso corporal nas medidas morfométricas de tilápia-do-nilo, linhagem GIFT-Epagri, e determinar as correlações destas medidas com o peso do corpo. Foram utilizados 325 machos e 272 fêmeas, derivados de sete diferentes populações do programa de melhoramento. De cada indivíduo foram avaliados os seguintes parâmetros: peso corporal (PC), comprimento total (CT), comprimento padrão (CP), comprimento do tronco (CTr), comprimento da cabeça (CC), altura corporal (AC) e largura corporal (LC). Posteriormente, foram determinadas as seguintes relações: fator de condição de Fulton (FC), CC/CP, AC/CP, LC/CP e CTr/CP. Os indivíduos selecionados para peso corporal das diferentes populações apresentaram maior FC e AC/CP, em relação aos indivíduos não selecionados. Além disso, todas as correlações entre as variáveis analisadas foram altas (acima de 0,70), indicando que na seleção dos indivíduos com maior peso há boa possibilidade de haver ganhos indiretos para outras características desejáveis. Abstract - This study aimed to evaluate the effect of individual selection for body weight on morphometric characteristics of the Nile tilapia, Gift-Epagri strain, and as well as to determine the phenotypic correlations of these measurements. We used 325 males and 272 females derived from seven different populations of the breeding program. The following morphometric characteristics were measured: body weight (BW), total length (TL), standard length (SL), corrected length (CL), head length (HL), body height (BH) and body width (BW). Thereafter, the data were used to determine the following ratios: Fulton condition factor (FC), HL/SL, BH/SL, BW/SL and CL/SL. Fish selected for body weight showed greater FC and BH/SL compared to unselected fish. In addition, all correlations between variables were high (above 0.70), indicating that the selection of individuals with higher body weight may provide indirect gains in other desirable characteristics.O objetivo deste estudo foi avaliar o efeito da seleção individual para peso corporal nas medidas morfométricas de tilápia-do-nilo, linhagem GIFT-Epagri, e determinar as correlações destas medidas com o peso do corpo.

Integrated human formation: guiding category of professional and technological education / Formação humana integrada: categoria diretora da educação profissional e tecnológica

The present study is a bibliographic investigation that sought to analyze how Professional and Technological Education (EPT, from the acronym in Portuguese) and understand the concept of integrated human formation. Thus, based on the contributions of Ramos (2009) and Ciavatta (2012), the concept of integrated human formation was analyzed, its main objectives and its importance for EPT to differ from a mere technical education still in force in our educational model. The methodology consisted of file and bibliographic review followed by content analysis. It was concluded that, due to the search for the understanding of a whole, integrality is necessary for Professional and Technological Education, so that it does not continue the reproduction of educational duality, in one of the two partialities of knowledge, not just general education and not just technical education, but the training of a complete man who has a professional qualification, an education that emancipates individuals, in a full understanding of the world. It seeks to free individuals from a fragmented worldview, forming them in all their fullness as a human being, a being who understands the importance of work, science, and culture

Immunity to Lutzomyia intermedia Saliva Modulates the Inflammatory Environment Induced by Leishmania braziliensis

Transmission of Leishmania parasites occurs during blood feeding, when infected female sand flies inject humans with parasites and saliva. Chemokines and cytokines are secreted proteins that regulate the initial immune responses and have the potential of attracting and activating cells. Herein, we studied the expression of such molecules and the cellular recruitment induced by salivary proteins of the Lutzomyia intermedia sand fly. Of note, Lutzomyia intermedia is the main vector of Leishmania braziliensis, a parasite species that causes cutaneous leishmaniasis, a disease associated with the development of destructive skin lesions that can be fatal if left untreated. We observed that L. intermedia salivary proteins induce a potent cellular recruitment and modify the expression profile of chemokines and cytokines in mice. More importantly, in mice previously immunized with L. intermedia saliva, the alteration in the initial inflammatory response was even more pronounced, in terms of the number of cells recruited and in terms of gene expression pattern. These findings indicate that an existing immunity to L. intermedia sand fly induces an important modulation in the initial immune response that may, in turn, promote parasite multiplication, leading to the development of cutaneous leishmaniasis

A study of CP violation in the decays B±→[K+K-π+π-]Dh± (h= K, π) and B±→[π+π-π+π-]Dh±

The first study of CP violation in the decay mode B±→[K+K-π+π-]Dh± , with h= K, π , is presented, exploiting a data sample of proton–proton collisions collected by the LHCb experiment that corresponds to an integrated luminosity of 9 \,fb - 1 . The analysis is performed in bins of phase space, which are optimised for sensitivity to local CP asymmetries. CP -violating observables that are sensitive to the angle γ of the Unitarity Triangle are determined. The analysis requires external information on charm-decay parameters, which are currently taken from an amplitude analysis of LHCb data, but can be updated in the future when direct measurements become available. Measurements are also performed of phase-space integrated observables for B±→[K+K-π+π-]Dh± and B±→[π+π-π+π-]Dh± decays

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Hydrogen peroxide and chlorine dioxide against parasite Ichthyophthirius multifiliis (Protozoa, Ciliophora) in jundiá fingerlings

<div><p>ABSTRACT: Ichthyophthiriasis is a worldwide fish disease with great financial impact on freshwater fish farming due to its associated high mortality rates. Current study assesses the parasiticidal capacity of hydrogen peroxide (H2O2) and chlorine dioxide (ClO2) against the causative agent, Ichthyophthirius multifiliis, in jundiá. Median lethal concentration (LC50, 96h) of each chemical agent was established, as well as the minimum inhibitory concentration of hydrogen peroxide for the parasite´s infectious larval phase (theront). Products were tested asynchronously in parasitized fingerlings for short and long baths at the following concentrations and exposure times: 1. Hydrogen peroxide: (T1) continuous bath - 30ppm and (T2) 50ppm; (T3) short bath - 150ppm, during 1h and (T4) 250ppm during 1h; control group (without any chemical agent). 2. Chlorine dioxide: (T1) continuous bath - 4ppm and (T2) 20ppm; (T3) short bath - 200ppm, during 1min; (T4) short bath - 400ppm, during 1min and control group. Data analysis demonstrated a concentration of 82.54ppm of the commercial product (or 24.76ppm of the active chemical agent) as LC50, 96h of H2O2 and 38.4ppm product (or 2.68ppm of the active chemical agent) for ClO2. Hydrogen peroxide concentration causing 100% mortality rate of theronts in 1h was 25ppm (product, or 7.5ppm of the active chemical agent). At the end of the fourth day of curative experiment, 98% of the animals died by ichthyophthiriasis. No treatment was effective against the parasite.</p></div
