Introduction: Due to the prevalence of skin problems in patients after radiotherapy, skin dose measuring is importance. Content: Skin in vivo dosimetry means measuring the patient's (or phantom) skin dose during radiotherapy. According to the ICRP 59, the dose at the depth of 0.07 mm is known as a skin dose. The most radiosensitive epidermis cells are located...

Introduction: The most modern radiotherapy devices are equipped with an Electronic Portal Imaging Device (EPID) system which is located on opposite side of the machine’s head. EPID system is often used to setting up the position verification during or between radiotherapy sessions. Material and Methods: Various types of dosimeters have been used to setting up ...

Background: The SALL4/Sall4 is constitutively expressed in human and mice. SALL4 mRNA could be used as a marker for the diagnosis of different types of cancers. On the other hand, chrysin has diverse biological properties. Objectives: In the present study, the effect of the chrysin was investigated on the CT26 colon cancer in vitro and in vivo. Furthermore, the expression levels of the stem cel...

      Insulin-loaded biodegradable chitosan nanoparticle was prepared by the polyelec-trolyte complex formation method. The prepared nanoparticles were in the size of 110 nm and had high entrapment (91.0%) capacity. The transdermal nanoinsulin was characterized by in vivo hypoglycemic effects. Plasma glucose was decreased to the range of 80.34 to 96.74 mg/dl, and insulin levels were in...

Drug-induced cholestasis is the main type of liver disorder accompanied by high morbidity and mortality. Evidence for the role of hepatobiliary pumps in the cholestasis patho-mechanism is constantly increasing. Recognition of the interactions of chemical agents with these transporters at the initial phases of drug discovery can help develop new drug candidates with low cholestasis potential. Th...
