Tumor classification is a well-studied problem in the field of bioinformatics. Developments in the field of DNA chip design have now made it possible to measure the expression levels of thousands of genes in sample tissue from healthy cell lines or tumors. A number of studies have examined the problems of tumor classification: class discovery, the problem of defining a number of classes of tumo...

Objective: In the present study, it was aimed to investigate differences between clinical and histopathological features of testicular seminomatous non-seminomatous germ cell tumors diagnosed in our center recent 10 years. Methods: All patients whom diagnosis tumor histologically confirmed January 2010 May 2020 were involved study. The medical records screened Hematoxylin-Eosin (H+E) stained sl...

Purely extradural giant lumbar schwannomas are rare lesions. Classification of these tumors is performed according to the sizes and spills and is named the modified Sridhar's classification. The management of these tumors has traditionally been performed by combined antero-posterior large or two-stage exposures. This combined exposure has many disadvantages. Recent reports have demonstrated the...

Neuroendocrine tumors may develop throughout the human body with the majority being found in the gastrointestinal tract and bronchopulmonary system. Neuroendocrine tumors are classified according to the grade of biological aggressiveness (G1-G3) and the extent of differentiation (well-differentiated/poorly-differentiated). The well-differentiated neoplasms comprise typical (G1) and atypical (G2...

Scene gist, a viewer's holistic representation of a scene from a single eye fixation, has been extensively studied for terrestrial views, but not for aerial views. We compared rapid scene categorization of both views in three experiments to determine the degree to which diagnostic information is view dependent versus view independent.We found large differences in observers' ability to rapidly c...

Gliomas are the most common primary human brain tumors. They comprise a heterogeneous group of benign and malignant neoplasms that are histologically classified according to the World Health Organization (WHO) classification of tumors of the nervous system. Over the past 20 years the cytogenetic and molecular genetic alterations associated with glioma formation and progression have been intense...

Brain tumors are life-threatening for adults and children. However, accurate timely detection can save lives. This study focuses on three different types of brain tumors: Glioma, meningioma, pituitary tumors. Many studies describe the analysis classification tumors, but few have looked at problem feature engineering. Methods needed to overcome drawbacks manual diagnosis conventional feature-eng...

PURPOSE Rosai et al. published the World Health Organization (WHO) classification of thymic epithelial tumors in 1999, and its clinical usefulness seems to be established. It is our purpose to find the clinically relevant diagnostic points in the WHO Histological Classification of Thymoma. METHODS Thymomas surgically removed from 100 consecutive patients at Juntendo University Hospital betwee...
