background: recently, it has been indicated that x-ray coherent scatter from biological tissues can be used to access signature of tissue. some scientists are interested in studying this effect to get early detection of breast cancer. since experimental methods for optimization are time consuming and expensive, some scientists suggest using simulation. monte carlo (mc) codes are the best option...

background: fish have been at high risk of atrazine toxicity. comparative atrazine toxicity on the tissues of clarias gariepinus is scanty. therefore, acute and chronic effects of atrazine on some biochemical parameters in clarias gariepinus were investigated in this study. methods: atrazine toxicity was determined by assessing the responses of glucose, protein, alanine aminotransferase (alt), ...

introduction: gutta-percha (gp), is a neutral and non-toxic material. the aim of this animal study was to compare the biocompatibility of nanosilver coated gp (ns-gp) with conventional gp in subcutaneous tissues in a rat model. methods and materials: conventional gp and ns-gp were subcutaneously implanted in the backs of 20 male wistar rats ( n =10). a control animal was assigned for each trial...

in this article we review the application and procedures involved in scanning electron microscope (sem) to observe biological and live tissues through using sem at high resolution. we discuss practical methods for optimizing tissue preservation to achieve the two principal goals of biological specimen preparation: (a) preserving biological structures as close to their living configuration as po...

Hydatid disease, caused by larval stage of Echinococcus granulosus, is a common parasitic infection of human and animal. Although liver and lung are the most commonly affected area, hydatid cyst may develop any part of the body. Primary subcutaneous hydatid cyst is extremely rare. We report a case of 54 years old man who presented with palpable mass in scapular region from 3 years ago....

We report a 75-year old female patient with advanced emphysema. After endoscopic lung volume reduction with endobronchial valves (EBV), a huge pneumatocele has occured and resolved spontaneously within a few weeks. Albeit rare, pneumatoceles should be considered in patients with relapsing dyspnoe after EBV treatment.
