Introduction: Krupple-like factor4 is a transcription factor which is involved in many cancers including Breast cancer. Breast cancer is the most common malignancy among women. Due to the high prevalence of these tumors, there are ongoing efforts to find molecular markers which can recognize nontumoral from tumoral tissues. Therefore, the aim of this study was to evaluate the potential usefulne...
Accumulating evidence suggests that renal cell tumors represent a group of histologically and molecularly heterogeneous diseases, even within the same histological subtype. In accordance with the increased understanding of the morphological, immunohistochemical, molecular, and epidemiological characteristics of renal cell tumors, the World Health Organization (WHO) classification of renal cell ...
A brain tumor is the cause of abnormal growth cells in brain. Magnetic resonance imaging (MRI) most practical method for detecting tumors. Through these MRIs, doctors analyze and identify tissue can confirm whether affected by a or not. Today, with emergence artificial intelligence techniques, detection tumors done applying techniques algorithms machine learning deep learning. The advantages ap...
The National Toxicology Program (NTP) classification system for rat and mouse ovarian tumors is presented. The classification system is based on previous classification systems and on a review of all the primary ovarian tumors from the archives of the National Cancer Institute (NCI) and NTP Carcinogenesis Testing Programs. The relative frequency and principal diagnostic features of 204 ovarian ...
Soft computing models based on intelligent fuzzy systems have the capability of managing uncertainty in the image based practices of disease. Analysis of the breast tumors and their classification is critical for early diagnosis of breast cancer as a common cancer with a high mortality rate between women all around the world. Soft computing models based on fuzzy and evolutionary algorithms play...
pleuropulmonary blastoma (ppb) is a rare, malignant intrathoracic tumor that occurs mostly in children before 5 years old. it consists about 15% of all primary pediatric pulmonary tumors and shows various mesenchymal components. its presentations are nonspecific and common symptoms include fever, cough, chest pain, respiratory distress, and pulmonary infection. ppb should be considered in the d...
using complement fixation technique, serial serum samples from 15 patients undergoing surgical removal of malignant tumors were assayed for the presence of tumors antibodies against the cellular fractions of both normal and carcinomatous tissue. antibody responses against tumor associated antigens were detected in four cases. in all cases antibody activity was directed only against the supernat...
CONTEXT The World Health Organization (WHO) recently published its 4th edition of the classification of tumors of the central nervous system, incorporating a substantial number of important changes to the previous version (WHO 2000). The new WHO classification introduces 7 changes in the grading of central nervous system neoplasms, ranging in significance from minor to major, in categories of a...
background and aims. head and neck tumors are the most common complaints of people referring to different medical sections, especially in children. the aim of this study was to evaluate the prevalence of these tumors in children less than 12 years of age to provide a better perspective for future studies. materials and methods. all the files in department of pathology at tabriz pediatric hospit...
background: understanding the differences in genetics of malignancies is crucial for therapeutic decisions. this systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. material and methods: we performed a systematic review of the literature published on genetics of pediatrics bone tumors, using pubmed, google scholar, scie...
