1. Differentiation of affected and nonaffected ovaries in ovarian torsion with magnetic resonance imaging texture analysis
SUMMARY OBJECTIVE: This study aimed to evaluate the feasibility of texture analysis on T2-weighted axial images in differentiating affected and nonaffected ovaries in ovarian torsion. METHODS: We included 22 torsioned ovaries and 19 healthy ovaries. All patients were surgically proven ovarian torsion cases. On T2-weighted axial images, ovarian borders were

2. Are clinicopathological features of the isthmic thyroid nodule different from nodules in thyroid lobes? A single center experience
ABSTRACT Objectives: Thyroid nodules located in isthmus were found less prevalent, although papillary thyroid cancer in this location was reported to be more aggressive behaviour in some studies. Our aim was to evaluate hormonal,ultrasonographic, and cytopathologic features of nodules located in isthmus (isthmic nodules). Subjects and methods: Patients who

3. Follicular Lesions with Papillary Nuclear Characteristics: Differences in Chromatin Detected by Computerized Image Analysis
ABSTRACT Objective: Follicular lesions of the thyroid with papillary carcinoma nuclear characteristics are classified as infiltrative follicular variant of papillary thyroid carcinoma-FVPTC (IFVPTC), encapsulated/well demarcated FVPTC with tumour capsular invasion (IEFVPTC), and the newly described category “non-invasive follicular thyroid neoplasm with p

4. A Novel Run-length based wavelet features for Screening Thyroid Nodule Malignancy
Abstract: Thyroid nodules are cell growths in the thyroid which might be for in one of two categories benign or malignant. Nodular thyroid disease is common and because of the associated risk of malignancy and hyper-function; these nodules have to be examined thoroughly. Hence diagnosing thyroid nodule malignancy in the early stage can mitigate the possibili

5. Potential of Texture Analysis for Charcoal Classification
Abstract Charcoal produced from reforested wood can be distinguished from the charcoal derived from the wood of native species. This identification is very important for the trade, control and monitoring of charcoal production in Brazil. This study investigated the potential of texture analysis for classifying the charcoal based on origin (eucalyptus or nati

6. Intrinsic Orientation of Hydroxyapatite Grains on the Surface of Dense Pellets Produced by Uniaxial Pressing
Bioceramics synthesized in laboratories must undergo biological tests that consider the final format and all the processing steps involved in the production of the final device. However, in many cases, the synthesized materials are characterized in formats very different from those that will ultimately be implanted into the body. Once living cells are direct

7. Early and Accurate Model of Malignant Lung Nodule Detection System with Less False Positives
ABSTRACT The objective of this work is to identify the malignant lung nodules accurately and early with less false positives. ‘Nodule’ is the 3mm to 30mm diameter size tissue clusters present inside the lung parenchyma region. Segmenting such a small nodules from consecutive CT scan slices are a challenging task. In our work Auto-seed clustering based se

8. Breast density pattern characterization by histogram features and texture descriptors
Abstract Introduction Breast cancer is the first leading cause of death for women in Brazil as well as in most countries in the world. Due to the relation between the breast density and the risk of breast cancer, in medical practice, the breast density classification is merely visual and dependent on professional experience, making this task very subjective

9. Morpho-anatomy and chemical profile of native species used as substitute of quina (Cinchona spp.) in Brazilian traditional medicine. Part II: Remijia ferruginea
ABSTRACT This research is part of a larger study of the Brazilian species that are commonly referred to as "quinas" and used as substitute of Cinchona species. In this study, we have performed the botanical characterization of the stem bark of Remijia ferruginea (A. St.-Hil.) DC., Rubiaceae, by morphological and anatomical description, and the analysis of it

10. Morphoanatomical and physicochemical profile of Piper callosum: valuable assessment for its quality control
ABSTRACT Piper callosum Ruiz & Pav., Piperaceae, popularly known as “elixir-paregórico” and “matricá” in Brazil, is used in folk medicine to treat gonorrhea, general pain, and digestive disorders, and has repellent, astringent, diuretic, depurative, and haemostatic properties. Despite the fact that this plant is sold as a traditional phytotherapeut

11. An Empirical Evaluation of the Local Texture Description Framework-Based Modified Local Directional Number Pattern with Various Classifiers for Face Recognition
ABSTRACT Texture is one of the chief characteristics of an image. In recent years, local texture descriptors have garnered attention among researchers in describing effective texture patterns to demarcate facial images. A feature descriptor titled Local Texture Description Framework-based Modified Local Directional Number pattern (LTDF_MLDN), capable of enco

12. Breast tumor classification in ultrasound images using support vector machines and neural networks
Abstract Introduction The use of tools for computer-aided diagnosis (CAD) has been proposed for detection and classification of breast cancer. Concerning breast cancer image diagnosing with ultrasound, some results found in literature show that morphological features perform better than texture features for lesions differentiation, and indicate that a reduc
