1. First molecular and serological detection of Epizootic Hemorrhagic Disease virus in white tailed deer ( Odocoileus virginianus ) from Tamaulipas, Mexico
RESUMO Virus da doença hemorrágica epizoótica (EHDV) são arbovírus dsRNA transmitidos por mordidas do genus Culicoides que causam doenças em ruminantes domésticos e selvagens. Doença hemorrágica epizoótica (EHD) é considerada uma das doenças infecciosas mais importantes dos veados de cauda branca (WTD) na América do Norte. Alguns estudos no Nord

2. Robust pulmonary segmentation for chest radiography, combining enhancement, adaptive morphology and innovative active contours
Abstract Introduction Statistical data reveal that approximately 140 million radiological exams are performed annually in Brazil. These exams are designed to detect and to analyze fractures, caused by different types of trauma; as well as, to diagnose pathologies such as pulmonary diseases. For better visualization of those lesions or abnormalities, method

3. Geophysical prospection in tin mineral occurrence associated to greisen in granite São Sepé (RS)
Abstract The discovery of new mineral resources involves various research techniques through direct and indirect studies. The geophysical methods are important tools in the detection of deep deposits because they use the contrast between the physical properties of the hosting rocks and the mineralized zone. In this sense, electrical geophysical methods are w

4. Effect of secondary infection on epithelialisation and total healing of cutaneous leishmaniasis lesions
BACKGROUND Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE This study verified the influence of non-parasitic wound infection on wound closure (epithelialisa

5. Influences of the signal border extension in the discrete wavelet transform in EEG spike detection
Abstract Introduction The discrete wavelet transform is used in many studies as signal preprocessor for EEG spike detection. An inherent process of this mathematical tool is the recursive wavelet convolution over the signal that is decomposed into detail and approximation coefficients. To perform these convolutions, firstly it is necessary to extend signal

6. On the geometric modulation of skin lesion growth: a mathematical model for melanoma
Abstract Introduction Early detection of suspicious skin lesions is critical to prevent skin malignancies, particularly the melanoma, which is the most dangerous form of human skin cancer. In the last decade, image processing techniques have been an increasingly important tool for early detection and mathematical models play a relevant role in mapping the p

7. Spread of Phlebotominae in temperate climates: province of Córdoba, Argentina
We report the presence of the competent vector for Leishmaniaspp, Migonemyia migonei, and theEvandromyia cortelezzii-sallesi complex south of its known distribution in the central temperate region of Argentina, in the province of Córdoba. The persistence of this phlebotomine in the northern border of the province, its association with a case of cutaneous le

8. A comparison of left ventricular border detection techniques applied to 2D echocardiograms
INTRODUCTION: Cardiology has been one of the most important areas of medicine. For several applications to diagnose the heart functions diseases the measurement of left ventricular (LV) cavity area and LV fractional area change are of vital necessity. To achieve this task, it is necessary to trace the border of left ventricle, which manual tracing is a tedio

9. Detecção de bordas em imagens de ecocardiografia utilizando redes neurais artificiais. / Border detection in echocardiography images using artificial neural networks.
Por ser não-invasiva e de baixo custo, a Ecocardiografia tem se tornado uma técnica de diagnóstico muito utilizada para a determinação dos volumes sistólicos e diastólicos do ventrículo esquerdo a fim de se calcular, indiretamente, o volume de ejeção do ventrículo esquerdo, a razão de contração muscular das cavidades cardíacas, a fração de e

10. Tuberculose pulmonar em populações de Mato Grosso do Sul / Pulmonary tuberculosis in populations of Mato Grosso do Sul
With a notification of 71,000 cases and 4,800 deaths in Brazil in 2010, tuberculosis was the third cause of mortality among infectious diseases. To evaluate the situation of tuberculosis in the state of Mato Grosso do Sul, the present study was prepared. We conducted an ecological study, from the Information System of Injuries Notification (Sinan), was calcu

11. Comparação das alterações da motilidade segmentar e da perfusão miocárdica durante o estresse pela dobutamina-atropina, pela ecocardiografia com contraste e pela ressonância magnética, na detecção de doença arterial coronária obstrutiva / Comparison of wall motion and myocardial perfusion abnormalities during dobutamine-atropine stress with myocardial contrast echocardiography and magnetic resonance imaging for the detection of obstructive coronary artery disease
The detection of left ventricular (LV) wall motion abnormalities induced by pharmacological or physical stress has a well established role in the non-invasive determination of myocardial ischemia. However, following the temporal sequence of events in the ischemic cascate, perfusion heterogeneity is one of the earliest and may occur before wall motion abnorma
