1. Deficiência de macronutrientes em Cariniana estrellensis (Raddi) Kintze
Resumo O conhecimento dos efeitos da nutrição mineral sobre a fisiologia vegetal de espécies nativas é um importante auxílio para que se obtenha o sucesso desejado quando estas são usadas no reflorestamento ou na recuperação de áreas degradadas. A presente pesquisa avaliou as consequências da deficiência de macronutrientes em Cariniana estrellensi

2. Efficacy Analysis of a Script-based Guide for EVAR Execution: is it Possible to Reduce Patient Exposure to Contrast, Operative Time and Blood Loss even when Advanced Technologies are not Available?
ABSTRACT INTRODUCTION: Despite the patient and medical staff exposure to radiation in endovascular aneurysm repair, the benefits of this abdominal aortic aneurysm type of surgical management are justfied by minor recovery time and hospitalization, as well as an option for patients not elected to conventional open repair. In this minimally invasive surgical

3. Validação da técnica de subtração entre os SPECTs crítico e intercrítico e o corregistro com a ressonância magnética na localização da zona epileptogênica em pacientes com epilepsias intratáveis do lobo frontal / Validation of the subtraction of the ictal and interictal SPECTs aligned with magnetic resonance technique in the localization of the epileptogenic zone in patients with pharmacoresistant frontal lobe epilepsy
Pacientes com epilepsias farmacorresistentes estão cada vez mais se beneficiando do tratamento cirúrgico, dado o avanço nas técnicas de diagnóstico. Com a cirurgia, busca-se tornar o paciente livre de crises sem que para isso sejam provocados déficits neurológicos secundários. Para que isso seja alcançado é fundamental que a região cerebral epilep

4. O ß-hidroxibutirato modifica os processos de ativação e inativação dos canais para sódio e potássio em corpos celulares de neurônios dos gânglios das raizes dorsais de ratos.
Under physiological conditions, the ketone bodies -hydroxybutyrate, acetoacetate and acetone are products of -oxidation of fatty acids that occurs in hepatocytes in response to hypoglycemia. This process occurs during fasting, high fat diets (such as the ketogenic diet, used in cases of drug-resistant epilepsy) and during diabetes mellitus in order to meet t

5. Sistema visual de segmentação de objetos robusto à iluminação para monitoramento automático de tráfego de veículos terrestres
This study presents a proposal for a moving object segmentation system that is resistant to changes in lighting conditions and can detect and suppress moving shadows. The technique of background subtraction using mixtures of gaussians provided a basis for this study. To better deal with illumination changes, that technique was adapted to use the HSV color sp

6. Within-breath analysis of respiratory mechanics in asthmatic patients by forced oscillation
INTRODUCTION: The within-breath analysis of respiratory mechanics by the monofrequency Forced Oscillation Technique (mFOT) is of great interest in both physiopathology studies and the diagnosis of respiratory diseases. However, there are limited data on the use of this technique in the analysis of asthma. This study evaluates within-breath mechanics of asthm

7. Formulação dual em mecânica da fratura utilizando elementos de contorno curvos de ordem qualquer / Dual boundary element formulation in fracture mechanics using curved element of any order
This work presents the dual boundary element formulation applied to linear crack problem. The goal of this research is the evaluation of stress intensity factor for two-dimensional crack problem using three different techniques, which are: the technique of correlation of displacements, the technique based on the state of tension at the crack tip and J integr

8. A cost-effective background subtraction technique.
Background Subtraction is a very important task in image processing because its results are used in algorithms that recognize more complex object behaviors. This proposed research technique extracts movement evidences from difference: 1) between two consecutive frames; 2) between current frame and the fourth previous frame; and 3) between the current frame a

9. Differential expression of metallothionein type-2 homologues in leaves and roots of Black pepper (Piper nigrum L)
Black pepper (Piper nigrum L.), member of the family Piperaceae is indigenous to India and is one of the most widely used spices in the world. In this paper we report the results of our attempts to identify a set of genes differentially expressed in the leaves of Piper nigrum, which could facilitate targeted engineering of this valuable crop. A PCR-based Sup

10. Radiografia digital e a tecnica de subtração no monitoramento da desmineralização e remineralização do esmalte dentario / Digital radiography and the subtraction technique for monitoring dental enamel demineralization and remineralization
O objetivo deste estudo in vitro foi comparar dois protocolos de remineralização em lesões de cárie no esmalte dentário, avaliados por meio de análises de cálcio (Ca) e fósforo (Pi), dureza do esmalte, microscopia de luz polarizada e subtração radiográfica digital (SRD); avaliar a viabilidade da utilização de dois diferentes sistemas de radiogra

11. Chromosome evolution: Karyotype variability in Platyrrhini and studies of sinteny and homologies between human chromosomes / Evolução cromossômica: estudo da variabilidade cariotípica em Platyrrhini e das homeologias e sintenias com cromossomos humanos
We studied the karyotypes of Brazilian monkeys (Platyrrhini, Primates) using both traditional cytogenetic techniques as well as FISH. FISH analysis employed human probes for chromosome 14, 15 and the X chromosome and a probe of the Y chromosome of Brachyteles arachnoides obtained by chromosome microdissection. Twenty-four individuals of Alouatta guariba clam

12. Estudo comparativo entre a fixação interna e a fixação in-termaxilar no reparo ósseo de fraturas mandibulares por meio de imagem radiográfica digital.
Conventional radiographic evaluation of fracture healing is not a reliable method, because it depends on the examinators experience and the quality of the exam. Therefore, serial images differing in density, contrast and geometrical projection can lead to a misdiagnosis on the postoperative fracture healing. Even in good quality images, little changes in cal
