4. Characterization of Leiurus abdullahbayrami (Scorpiones: Buthidae) venom: peptide profile, cytotoxicity and antimicrobial activity
Background Scorpion venoms are rich bioactive peptide libraries that offer promising molecules that may lead to the discovery and development of new drugs. Leiurus abdullahbayrami produces one of the most potent venoms among Turkish scorpions that provokes severe symptoms in envenomated victims. Methods In the present study, the peptide profile of the v

5. Breast hamartoma: a clinicopathologic analysis of 27 cases and a literature review
OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, a

6. Texture analysis of masses in digitized mammograms using Gleason and Menhinick diversity indexes
INTRODUCTION: Breast cancer is the second most common type of cancer in the world, being more common among women and representing 22% of all new cancer cases every year. The sooner it is diagnosed, the better the chances of a successful treatment are. Mammography is one way to detect non-palpable tumors that cause breast cancer. However, it is known that the

7. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

8. IMPLEMENTAÇÃO DE UM SISTEMA DE TELEDIAGNÓSTICO PARA CLASSIFICAÇÃO DE MASSAS EM IMAGENS MAMOGRÁFICAS USANDO ANÁLISE DE COMPONENTES INDEPENDENTES / IMPLEMENTATION OF A SYSTEM OF TELEDIAGNOSIS FOR CLASSIFICATION OF MASSES IN MAMMOGRAPHIC IMAGES USING INDEPENDENT COMPONENT ANALYSIS
This thesis proposes the modeling and implementation of a telediagnostic system for analysis and detection of lesions in mammographic images based on independent component analysis and support vector machine. The system analyzes images from digital mammography sent over the Internet and provides a diagnostic, indicating the presence of suspicious regions, wh

9. CLASSIFICAÇÃO DE MASSAS NA MAMA A PARTIR DE IMAGENS MAMOGRÁFICAS USANDO ÍNDICE DE DIVERSIDADE DE SHANNON-WIENER / CLASSIFICATION OF BREAST MASSES IN MAMMOGRAPHY IMAGES FROM USING INDEX OF SHANNON-WIENER DIVERSITY
O câncer é um dos maiores problemas de saúde mundial, sendo o câncer de mama o que mais causa óbito entre as mulheres e o segundo tipo mais freqüente no mundo. As chances de uma paciente sobreviver ao câncer de mama aumentam à medida que a doença é descoberta mais cedo. Diversos Sistemas de Detecção e Diagnóstico auxiliados por computador (Compu

10. Endoscopic ultrasound-guided biopsies for mediastinal lesions and lymph node diagnosis and staging
OBJECTIVES: To disseminate transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) as an alternative to investigate mediastinal tumoral lesions because it is an underused modality that has been available in Brazil for more than 15 years. METHODS: Descriptive analysis of a single endoscopy service's experience since 1997 in the accomplishment of EU

11. DETECÇÃO DE REGIÕES SUSPEITAS E CLASSIFICAÇÃO DE MASSAS EM MAMOGRAFIAS DIGITAIS UTILIZANDO DESCRIÇÃO ESPACIAL COM FUNÇÃO VARIOGRAMA / DETECTION OF SUSPICIOUS REGIONS AND CLASSIFICATION OF MASSES DESCRIPTION USING DIGITAL MAMMOGRAPHY IN SPACE VARIOGRAM FUNCTION
A mamografia é um exame de mama, utilizado de forma preventiva ao câncer de mama e também como método diagnóstico. Este exame, que consiste em uma radiografia das mamas, permite a detecção do câncer. O objetivo deste trabalho é utilizar técnicas de processamento de imagens e visão computacional para auxiliar especialistas na detecção de regiões

Breast cancer presents high occurrence frequency among the world population and its psychological effects alter the perception of the patients sexuality and the own personal image. Mammography is an x-ray of the mamma that allows the precocious detection of cancer, since it is capable to showing lesions in their initial stages, typically very small lesions i
