Avaliação da uniformidade de aplicação de água em gotejadores em função do teor de ferro

Este trabalho teve por objetivo estudar a variação de vazão em tubogotejadores NaanPC laranja e NaanPC azul em função de precipitados químicos, ao longo do tempo de funcionamento, quando submetidos a uma água rica em ferro, avaliando-se especificamente o coeficiente de uniformidade de Christiansen (CUC) e o coeficiente de uniformidade de distribuição (CUD). O experimento foi desenvolvido em uma bancada de ensaios para tubogotejadores no Laboratório de Ensaio de Equipamentos para Irrigação do Departamento de Engenharia Rural da Faculdade de Ciências Agronômicas - UNESP, localizado no município de Botucatu – SP. O experimento foi montado em esquema fatorial 2x2x7, sendo duas doses de Fe, dois modelos de gotejadores e sete tempos de funcionamento, com três repetições, totalizando 84 parcelas experimentais. Efetuou-se a análise de variância pelo teste F. As médias das vazões dos gotejadores foram comparadas pelo teste de T de Student a 5% de probabilidade. Os resultados obtidos não apontaram diferença significativa nas diferentes doses de ferro. Entretanto, os resultados apontaram diferença significativa na interação gotejador x tempo e coeficiente de uniformidade de Christiansen (CUC).

Latin-American Society Of Forensic Genetics (SLAGF) results of the Interlaboratory Quality Control Exercise 2010-2011

Latin-American Society of Forensic Genetics (SLAGF) Interlaboratory Quality Control Exercise (2010-2011) included the analysis of three bloodstain samples in FTA Classic Card (three persons, biologically unrelated) and one theoretical exercise. There were 56 participating laboratories from 13 Latin-American countries that belong to society, were reported 70 STRs, including autosomal and sex chromosome markers with consensus in 53 STRs with a rate in reporting errors of 2.3%. Fifty-six laboratories reported results in theoretical exercise with mistakes in calculation of IP for each marker. It is necessary to hold meetings to discuss the results of this exercise to reach conclusions and recommendations on all aspects of DNA forensics analysis and paternity test, to improve results and quality in the results of each laboratory. © 2011 Elsevier B.V.

American visceral leishmaniasis: Factors associated with lethality in the state of São Paulo, Brazil

Objectives. To identify factors associated with death in visceral leishmaniasis (VL) cases. Patients and Methodology. We evaluated prognostic factors for death from VL in São Paulo state, Brazil, from 1999 to 2005. A prognostic study nested in a clinical cohort was carried out by data analysis of 376 medical files. A comparison between VL fatal cases and survivors was performed for clinical, laboratory, and biological features. Association between variables and death was assessed by univariate analysis, and the multiple logistic regression model was used to determine adjusted odds ratio for death, controlling confounding factors. Results. Data analysis identified 53 fatal cases out of 376 patients, between 1999 and 2005 in São Paulo state. Lethality was 14.1 (53/376), being higher in patients older than fifty years. The main causes of death were sepsis, bleeding, liver failure, and cardiotoxicity due to treatment. Variables significantly associated with death were severe anemia, bleeding, heart failure, jaundice, diarrhea, fever for more than sixty days, age older than fifty years, and antibiotic use. Conclusion. Educational health measures are needed for the general population and continuing education programs for health professionals working in the affected areas with the purpose of identifying and treating early cases, thus preventing the disease evolution towards death. © 2012 Geraldine Madalosso et al.

Evolução de pacientes com AIDS pós cART: Evolução clínica e laboratorial de pacientes com AIDS após 48 semanas de tratamento antirretroviral

Combination Antiretroviral Therapy (cART) aims to inhibit viral replication, delay immunodeficiency progression and improve survival in AIDS patients. The objective of this study was to compare two different schemes of cART, based on plasma viral load (VL) and CD4+ T lymphocyte count, during 48 weeks of treatment. For this purpose, 472 medical charts of a Specialized Outpatient Service were reviewed from 1998 to 2005. Out of these, 58 AIDS patients who had received a triple drug scheme as the initial treatment were included in the study and two groups were formed: Group 1 (G1): 47 individuals treated with two nucleoside reverse-transcriptase inhibitors (NRTI) and one non-nucleoside reverse-transcriptase inhibitor; Group 2 (G2): 11 patients treated with two NRTI and one protease inhibitor. In G1 and G2, 53.2% and 81.8% respectively were patients with an AIDS-defining disease. The T CD4+ lymphocyte count increased progressively up until the 24th week of treatment in all patients, while VL became undetectable in 68.1% of G1 and in 63.6% of G2. The study concluded that the evolutions of laboratory tests were similar in the two treatment groups and that both presented a favorable clinical evolution.

Importância do exame laboratorial no diagnóstico de linfoma em cães e gatos

Lymphoma is a cancer originating in solid hematopoietic tissue and is one of the most common tumors in dogs and cats. Usually the diagnosis is made late, when the disease is at an advanced stage, reducing the success of treatment, affecting the prognosis. Therefore, early diagnosis is the best tool to combat this increasingly common disease in veterinary medicine. Due to the diversity of presentations and forms of the disease, clinical signs are nonspecific and varied making the use of laboratory testing essential to lymphoma diagnosis in order of establishing the most appropriate treatment as quickly as possible, giving the patient a longer survival rate

Modeling field load tests in lateritic unsaturated soil

Many models for unsaturated soil have been developed in the last years, accompanying the development of experimental techniques to deal with such soils. The benchmark of the models for unsaturated soil can be assigned to the Barcelona Basic Model (BBM) now incorporated in some codes such as the CODE_BRIGHT. Most of those models were validated considering limited laboratory test results and not much validation is available considering real field problems. This paper presents modeling results of field plate load tests performed under known suction on a lateritic unsaturated soil. The required input data were taken from laboratory tests performed under suction control. The modeling nicely reproduces field tests allowing appreciating the influence of soil suction on the stress-settlement curve. In addition, wetting induced or collapse settlements were calculated from field tests and were nicely duplicated by the numerical analysis performed.
