introduction: aim of this study was to assess the association between prostate calcification in transrectalultrasound (trus) and sono- guided needle biopsy in prostate cancer (pca). methods: a cross-sectional study was performed on patients referred to imam khomeini hospital between 2005 and 2011 who underwent trus biopsy due to increased psa or abnormal dre. the serum levels of psa, prostate v...
Breast cancer is one of the most frequently occurring disease which leads even to death among women community. The appearance of micro-calcifications in mammograms is an early sign of breast cancer. To overcome the issue, automated micro-calcification detection techniques play a vital role in cancer diagnosis and treatment. In this paper we proposed Support Vector Machine (SVM) based classifier...
Ectopic calcification can cause pain and limit mobility. Studies suggest that circadian genes may play a role in the calcification process. Core circadian genes Clock, Npas2, and Bmal1 are transcription factors that form CLOCK:BMAL1 or NPAS2:BMAL1 transactivator complexes that drive the rhythmic expression of circadian oscillator genes and output genes. Circadian oscillator genes Period1-3 and ...
BACKGROUND The aim of this study was to determine the fundamental relationships between cervical intervertebral disc (IVD) degeneration, endplate calcification, and the patency of endplate marrow contact channels (MCC). MATERIALS AND METHODS Sixty cervical IVDs were excised from 30 human cadavers. After sectioning the specimens underwent micro computed tomography (microCT) - from all images t...
Ossification of the Posterior Longitudinal Ligament (OPLL) is a disease that is characterized by the ectopic calcification of the ligament; however, the pathogenesis of OPLL remains to be investigated. We attempted to identify the in vivo role of Runx2, a master regulator of osteoblast differentiation and skeletal mineralization, in the pathogenesis of OPLL. The expression of Runx2 in the ligam...
Ectopic calcification is a driving force for a variety of diseases, including kidney stones and atherosclerosis, but initiating factors remain largely unknown. Given its importance in seemingly divergent disease processes, identifying fundamental principal actors for ectopic calcification may have broad translational significance. Here we establish a Drosophila melanogaster model for ectopic ca...
endocrine tumors of the pancreas (islet-cell tumors) are rare with neuroendocrine origin. the patient was a 41- year- old man, admitted with chief complains of epigastric mass feeling, dull abdominal pain, lack of appetite and weight loss up to 2-3 kg since 6 months ago. in physical examination, a mass was detected in epigaster and left upper quadrant (luq). in abdominal x-ray, a calcified mass...
We investigated the effect of zooplankton feeding on tissue and skeletal growth of the scleractinian coral Stylophora pistillata. Microcolonies were divided into two groups: starved corals (SC), which were not fed during the experiment, and fed corals (FC), which were abundantly fed with Artemia salina nauplii and freshly collected zooplankton. Changes in tissue growth, photosynthesis and calci...
