The automated classification of breast cancer histopathological images is one the important tasks in computer-aided diagnosis systems (CADs). Due to characteristics small inter-class and large intra-class variances images, extracting features for difficult. To address this problem, an improved autoencoder (AE) network using a Siamese framework that can learn effective from CAD was designed. Fir...

Transthoracic needle biopsy (TNB) is a fast and safe method used to establish definitive diagnosis for most thoracic lesions, whether the lesion is located in the pleura, the lung parenchyma, or the mediastinum. Diffuse disease and solitary lesions are equally approachable.TNB can avoid (when technically possible) more complex diagnostic interventions such asmediastinoscopy, thoracoscopy and ex...

in tropical and subtropical countries, envenomation by scorpions (so-called scorpionism) represents a serious public health problem. in the present study, the toxic effects of mice ld50 injections of mesobuthus eupeus (me) venom on the kidney and liver of anesthetized rabbits were investigated. six rabbits were selected and alt, ast, bun and creatinine were measured at 0, 1 and 3 hours after...

conclusions these results revealed that cirrhosis produce prolonged qt interval and sour cherry extract has an ameliorating effect on qt prolongation probably via its antiarrhythmic property. results results were analyzed by using student t-test and one-way anova. p < 0.05 was considered as significant level. the qt interval was calculated using the bazettʼs formula and corrected qt (qtc) was o...

the research was accomplished in order to study behavioral and histopathological effects of copper on rutilus rutilus caspicus under experimental condition. the study was performed using water static method during 96 hours. 15 fish with averaged weight 2?0.5 g in weight were encountered to different concentrations (0, 0.1, 0.2, 0.3, 0.4 mg/l) of copper. a group of fish was considered as control...

2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. it appears that tcdd is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. the prominent hepatotoxic effect of tcdd is progressive centrilobular necrosis. the is...
