RESUMO

The present work exhibits the dynamic viscosity profile data of three distinct nanofluids, at a constant shear stress, and within a range of temperatures that include below-ambient conditions (from -10 to 20 °C). The nanofluids were as follows. Nanofluid I: 30% ethylene glycol and 70% distilled water (v/v), with graphene (0.32% in mass); Nanofluid II: 30% engine coolant NBR 13705; ASTM D-3306; ASTM D-4985) and 70% distilled water (v/v), with graphene (0.2% in mass); and Nanofluid III: 30% engine coolant and 70% distilled water (v/v), with Multi-Walled Carbon Nanotubes (MWCNT) (0.2% in mass). The present work was motivated by the scarcity of experimental data on the temperature dependence of viscosity for graphene, MWCNT, and their hybrid nanofluids, at below-ambient temperatures.

RESUMO

The purpose of this study was to describe clinic-epidemiological characteristics of leishmaniasis cases attended at the Clinical Hospital of Federal University of Uberlândia (CHU), state of Minas Gerais, from January 2000 to December 2013. This is a descriptive and retrospective review of medical records of patients diagnosed with leishmaniasis and treated at the CHU. 168 cases of leishmaniasis were analyzed and most patients were male, aged 23 to 60 years. For cutaneous and mucosal leishmaniasis, single lesions, located mainly in lower limbs and head (CL) and nasal mucosa (ML), were the most common clinical presentation. Regarding the diagnosis, the most performed methods for CL and ML were biopsy plus histopathology and biopsy plus immunohistochemistry; biopsy plus direct parasitological examination methods were the most frequent for VL. Most patients (84%) received treatment, mainly glucantime for both CL and ML; VL treatment was based on amphotericin B or glucantime. According to data from Sistema de Informações de Agravos de Notificação (SINAN), the Brazilian information system to notify and investigate cases of diseases and their aggravations, no case has been confirmed as autochthonous. It is noteworthy the underreporting of cases and the lack of complete information in medical records. Our results may contribute to a better understanding of the real situation in Uberlândia region concerning to leishmaniasis.

O propósito desse estudo foi descrever as características clínico-epidemiológicas dos casos de leishmaniose atendidos no Hospital de Clínicas da Unversidade Federal de Uberlândia (HCU), Minas Gerais, de janeiro de 2000 a dezembro de 2013. Trata-se de uma revisão descritiva e retrospectiva de registros médicos de pacientes diagnosticados com leishmaniose e tratados no HCU. 168 casos diagnosticados com leishmaniose foram analisados e os pacientes, em sua marioria, foram homens, com idade entre 23 e 60 anos. Para a leishmaniose cutânea e mucosa, lesões únicas, localizadas principalmente nos membros inferiores e na cabeça (LC) e mucosa nasal (LM), foram as apresentações clínicas mais comuns. Em relação ao diagnóstico, os métodos mais realizados para LC e LM foram biópsia mais histopatologia e biópsia mais imunohistoquímica; biópsia mais parasitológico direto foi o mais frequente para LV. A maioria dos pacientes (84%) recebeu tratamento, principalmente glucantime tanto para LC quanto para LM; o tratamento para LV foi atribuido à anfotericina B ou glucantime. De acordo com os dados do Sistema de Informação de Agravos de Notificação (SINAN), o sistema de informação brasileiro para notificar e investigar casos de doenças e seus agravamentos, nenhum caso foi confirmado como autóctone. Ressalta-se a subnotificação dos casos e a informação incompleta nos prontuários médicos. Nossos resultados podem contribuir para um melhor entendimento da real situação da leishmaniose na região de Uberlândia.

RESUMO

Canine visceral leishmaniasis, a systemic and chronic zoonosis, is caused in Brazil by the protozoan Leishmania chagasi, a widely accepted synonym for Leishmania infantum. The agent and disease has recently arrived in Uberlândia city, Minas Gerais, Brazil. In this research, hematological parameters and gross lesions of dogs with visceral leishmaniasis were compared, to highlight aspects of disease in a recent outbreak. For this purpose forty mongrel dogs from Uberlândia seroreagents by ELISA and RIFI tests were selected. Animals were categorized as asymptomatic,(AS); oligosympytomatic (OS) and symptomatic (SS). Blood samples were collected and dogs were euthanized according to Brazilian Federal rules. Animals were then submitted to standard necropsy procedures at Veterinary Pathology sector of the Federal University of Uberlândia. Most prominent alterations were of observed in respiratory and integumentary systems, with pilose rarefaction (OS: 41.7%, SS: 60.1%), specially periocular (OS: 25.0 %, SS: 26.1%) and thoracic/pelvic members (OS: 25.0%, SS: 30.4%). Onychogryphosis (OS: 41.7%, SS: 39.1%), pulmonar edema (OS: 25.0%, SS: 39.1%), and congestion (OS: 41.7%, SS: 60.9%). Moreover animals displayed increase of several organs; liver (67.5%), spleen (60%), lymph nodes (72.5%) and kidney (47.5%). Hematological alterations included low red cell counts and decreased hemoglobin content. Overall, 27.5% of animals presented leukocitosis, 52.5 % of dogs had increased band neutrophil counts 5.0 % had basophilia and 42.5% monocytopenia. No correlations was found between hematological findings and clinical status of animals (asymptomatic, oligosymptomatic or symptomatic). Presumptively, we can conclude that, in asymptomatic animals there are hematological as well as gross alterations.(AU)

RESUMO

Apresenta alguns resultados do estudo sobre as práticas de médicos e farmacêuticos na cidade de São Pedro de Uberabinha (MG), hoje Uberlândia, durante as décadas de 1890 e 1920. A hipótese levantada é a de que, no período, a conformação de um mercado de serviços de saúde foi marcada, e em parte constituída, por conflitos e disputas protagonizados por médicos e farmacêuticos. A partir de tal hipótese, tento identificar a razão e os recursos utilizados por esses sujeitos na delimitação de seus espaços e suas práticas em relação à cura.(AU)

Some results are presented of a study into the medical and pharmacological practices in São Pedro de Uberabinha, Minas Gerais state, (today Uberlândia), between the 1890s and the 1920s. The basic hypothesis is that during the period in question, there existed a health service market that was marked and to some extent constituted by conflicts and disputes headed by physicians and pharmacists. Based on this hypothesis, I attempt to identify the reasons and resources used by these subjects to demarcate their spaces and healing practices.

RESUMO

Starting from an outbreak of a human cutaneous leishmaniasis, we proposed to investigate the natural dog infection, in rural and urban area of Uberlândia, Minas Gerais, Brazil. The dog were submitted to clinical, hemoparasitological and sorological diagnosis (indirect fluorescent antibody reaction): from 429 domestic dogs examined, 100 from the rural area and 329 from the urban area. The indirect fluorescent antibody reaction showed that 1% of the dogs from the rural area and 10,6% of dogs from the urban area were reagent for Leishmania. These findings seem to indicate that the dog represents an important role as reservatory of the infection, contributing with dissemination and formation of new foci of the endemic disease in the urban area.

A partir de um surto de Leishmaniose Tegumentar (LT) humana no Triângulo Mineiro e Alto Paranaíba, propusemos-nos investigar a infecção natural em cães em áreas rural e urbana do município de Uberlândia - Minas Gerais. Os cães foram submetidos a exames clínico, hemoparasitológico e sorológico (reação de imunofluorescência indireta). Foram examinados 429 cães sendo 100 da área rural e 329 da área urbana. A RIF1 demonstrou que 1% dos animais da zona rural e 10,6% dos animais da área urbana foram reagentes para Leishmania. Este achado parece indicar que a infecção canina na região de estudo é ativa e que o cão poderá representar um importante papel como reservatório da infecção, podendo participar na disseminação e formação de novos focos da endemia também em área urbana.

RESUMO

From 1981 to 1986, a study was conducted to assess the prevalence of gastro-intestinal parasites in dogs at the Veterinary Hospital of the FederalUniversity of Uberlândia, Minas Gerais. A total of 11.563 male and female dogs, of different breeds and ages were included. From these, 2.447 were diagnosed as having parasites in the feces (21.16%). Part of these dogs (1.672) were infested by one specie of parasite (68.32%) and 755 with various species (30.85%). The parasites found were the following: Ancylostoma spp (61.15%); Toxocara spp (24.45%); Dipylidium spp (8.28%); Isospora spp (4.62%); Trichuris spp (1.22%); Taenia spp (0.22%); Spirocerca spp (0.06%). Special attention was given to the Ancylostoma spp and Toxocara spp, responsible for zoonoses whose  incidence diminished year by year front the beginning of the study indicating a decrease tendency. In relation to the age intervals examined, the following data were obtained: 0 - 3 months old dogs, 28.2% infestation; 4 - 12 months old dogs, 36.33% and 13 - 24 months olddogs, 18.23% infestation. The results demonstrated that younger animals (to one year of age) were the most infected.

Durante o período de 1981 a 1986 estudou-se em cães, examinados clinicamente no Hospital Veterinário da Universidade Federal de Uberlândia, a prevalência de parasitos gastrintestinais. Foram atendidos 11.563 c.es de ambos os sexos, de diferentes raças e idades, dos quais 2.447 apresentaram diagnóstico coproparasitológico positivo (21,16%); destes, 1.672 com infecções simples (68,32%) e 755 com infecções múltiplas (30,85%). A prevalência de infecções simples foi a seguinte: Ancylostoma spp (61,15%); Toxocara spp (24,45%); Dipylidium spp (8,28%); Isospora spp (4,62%); Trichuris spp (1,22%); Taenia spp (0,22%) e Spirocerca spp (0,06%). Atenção especial foi dada aos parasitos Ancylostoma spp e Toxocara spp, responsáveis por zoonoses, cuja incidência, a partir de 1984, vem diminuindo ano a ano, e que apresentaram tendência decrescente. Em relação à faixa etária, foram encontrados 28,2% dos c.es parasitados entre 0 e 3 meses; 36,33% entre 4 e 12 meses; 18,23% entre 13 e 24 meses. Os resultados demonstraram que animais jovens de até um ano de idade foram os mais parasitados.
