Lattice Boltzmann Method for Evaluating Hydraulic Conductivity of Finite Array of Spheres
The hydraulic conductivity (K) represents an important hydrophysical parameter in a porous media. K direct measurements, usually demand a lot of work, are expensive and time consuming. Factors such as the media spatial variability, sample size, measurement method, and changes in the sample throughout the experiment directly affect K evaluations. One alternative to K measurement is computer simulation using the Lattice Boltzmann method (LBM), which can help to minimize problems such as changes in the sample structure during experimental measurements. This work presents K experimental and theoretical results (simulated) for three regular finite arrangements of spheres. Experimental measurements were carried out aiming at corroborating the LBM potential to predict K once the smallest relative deviation between experimental and simulated results was 1.4%
Extramedullary Plasmacytoma Diagnosed In An Hiv-positive Patient By An Unusual Clinical Presentation
The aim of this paper is to describe a case report of EMP in an HIV-positive patient. A 44-year-old, dark-skinned HIV-infected woman was referred to the Oral Diseases Treatment Center with a swelling at palate and left gingival fornix in the maxilla. Biopsy was taken and the oral lesion was diagnosed as EMP with well-differentiated plasma cells and restriction of the lambda light-chain. Skeletal survey was performed and no radiograph alterations were observed, thus supporting the diagnosis of EMP. Patient was referred to treatment and after two months of chemo and radiotherapy, an expanding lesion was observed in L5/S1 patient's vertebrae. Biopsy of the spinal lesion was consistent with lymphoma with plasmocitary differentiation, supporting the diagnosis of multiple myeloma (MM). Regarding the medical history, the final diagnostic was an oral extramedullary plasmacytoma with rapid progression into multiple myeloma. It is crucial to emphasize the relevance of HIV infection as a risk factor for both aggressive clinical behavior and unusual clinical presentation of extramedullary plasmacytoma cases

Ação de prolil-leucil-gliclnamida (PLG) na via nigroestriatal do rato
In order to study the nigrostriatal pathway, we obtained the rotatory behavior model in male Wistar rats by electrolytic lesion of the left lateral hypothalamic region. Animals thus lesioned displayed rotations toward the same side of lesion when apomorphine was administered, a result in disagreement with what has been obtained in the model with 6-hydroxydopamine lesion. The administration of PLG alone was not followed by rotatory behavior but when the compound was administered in low doses (0.25 to 1mg/kg) simultaneously with apomorphine to animals previously submitted to REM sleep deprivation, a significant increase in the number of rotations was observed in comparison with controls and groups receiving higher doses of PLG. These results indicate that PLG may act as, a modulator on dopamine receptors in the striatum.No intuito de estudar a via nigroestriatal, produzimos uma lesão na região hipotalâmica lateral de ratos Wistar. Os animais passavam a apresentar comportamento rotatório para o mesmo lado da lesão. A administração isolada do PLG não induziu o comportamento rotatório. Entretanto, com doses baixas do composto, concomitantemente à administração de apomorfina em animais previamente submetidos à privação de sono REM, observou-se aumento no número de rotações auando comparado ao grupo controle e aos grupos aue receberam doses altas de PLG. Estes achados sugerem que o PLG age como um modulador sobre os receptores dopaminérgicos do estriado.Escola Paulista de Medicina Department of Neurology and Neurosurgery Division of Extrapyramidal Diseases InvestigationEscola Paulista de Medicina Department of Neurology and Neurosurgery Head of the Division - Division of Extrapyramidal Diseases InvestigationUNIFESP, EPM, Department of Neurology and Neurosurgery Division of Extrapyramidal Diseases InvestigationEscola Paulista de Medicina Department of Neurology and Neurosurgery Head of the Division - Division of Extrapyramidal Diseases InvestigationSciEL

Model for End-Stage Liver Disease, Model for Liver Transplantation Survival and Donor Risk Index as predictive models of survival after liver transplantation in 1,006 patients
OBJECTIVES: Liver transplantation has not increased with the number of patients requiring this treatment, increasing deaths among those on the waiting list. Models predicting post-transplantation survival, including the Model for Liver Transplantation Survival and the Donor Risk Index, have been created. Our aim was to compare the performance of the Model for End-Stage Liver Disease, the Model for Liver Transplantation Survival and the Donor Risk Index as prognostic models for survival after liver transplantation. METHOD: We retrospectively analyzed the data from 1,270 patients who received a liver transplant from a deceased donor in the state of São Paulo, Brazil, between July 2006 and July 2009. All data obtained from the Health Department of the State of São Paulo at the 15 registered transplant centers were analyzed. Patients younger than 13 years of age or with acute liver failure were excluded. RESULTS: The majority of the recipients had Child-Pugh class B or C cirrhosis (63.5%). Among the 1,006 patients included, 274 (27%) died. Univariate survival analysis using a Cox proportional hazards model showed hazard ratios of 1.02 and 1.43 for the Model for End-Stage Liver Disease and the Model for Liver Transplantation Survival, respectively (
Seroprevalence of Trypanosoma cruzi Infection in Students at the Seven-Fourteen Age Range, Londrina, PR, Brazil, in 1995
Seropositivity for Chagas disease was evaluated in 834 children aged between 7 and 14 from the Municipal Teaching System in the district of Londrina, State of Paraná. A seroprevalence rate of 0.1% was found through the use of an indirect immunofluorescent test and an enzyme-linked immunosorbent assay. This low rate of seroprevalence provides evidence that the vectorial transmission of Chagas disease has been eliminated in Londrina. The main reason for the elimination of vectorial transmission of Trypanosoma cruzi infection, as evaluated by serological tests, may be a remarkable change in the economic structure of the northern region of Paraná in the 1960's. At that time coffee production was almost completely replaced by soy beans, wheat and grazing in the rural areas. This change deeply affected the rural ecology and caused an exodus of the population from rural to urban areas as well as a decrease in the total number of the population of that region. The measures introduced for controlling the disease through the Program of Chagas Disease Control established by the Fundação Nacional de Saúde of the Brazilian Ministry of Health, certainly, had a positive impact on the reduction of American trypanosomiasis prevalence in the area under study. However, it does not seem that this was the most relevant factor responsible for the elimination of vectorial transmission of Chagas disease in Londrina.Universidade Estadual de LondrinaUniversidade Federal de São Paulo (UNIFESP)Instituto Adolfo LutzUNIFESPSciEL
CARACTERÍSTICAS GRANULOMÉTRICAS DO SOLO DA FUNDAÇÃO CAIO MARTINS, SÃO FRANCISCO, MG
Este estudo busca apresentar o perfil granulométrico do solo da Fundação Caio Martins (FUCAM), área estadual localizada à beira do rio São Francisco, no município também denominado São Francisco, no Norte de Minas Gerais. Para isso coletou-se amostras de solo no ano de 2016 e através do uso de peneiras próprias do laboratório de Laboratório de Mecânica dos Solos da UFOP, foi possível reconhecer o perfil granulométrico de cada uma das seis amostragens realizadas que representavam toda a área de estudo pesquisada. Como resultado foi possível afirmar que todas as amostras apresentaram textura siltosa, destacando-se o fato de que a medida que a ação antrópica por local de coleta era detectada, maiores frações de pedregulho eram detectadas, por consequência, o aumento do perfil síltico por região amostral se dá à medida que o solo se apresenta mais conservado da ação humana, sendo possível afirmar que o mais degradado, sobre a ótica granulométrica é exatamente o setor Leste, onde se localizam a maior parte das atividades impactantes do local e onde estão a maior parte das ações da Fundação. Obviamente mais estudos, em especial o geoquímico, são importantes de serem realizados para se afirmar quais as espécies mais adequadas ao cultivo, mas sob um ponto de vista granulométrico do solo, todos os vegetais arbóreos originários do Cerrado são indicados para o plantio na área da FUCAM
