Theileria equi and Babesia caballi are the causative agents of equine piroplasmosis (EP). Currently, imidocarb dipropionate (ID) is only available drug for treating clinical form EP. Serious side effects incomplete clearance infection a major drawback ID. Heat-shock proteins (Hsp) play vital role in life cycle these haemoprotozoans by preventing alteration protein conformation. These Hsp activa...

introduction gallium-67 (67ga) has been used as a radionuclide for imaging a variety of solid tumors since 1969. since then use of various gallium-based radiotracers has been reported. recently, 67ga-labeled acetylacetate bis(thiosemicarbazones) (67ga-aats) complex with significant tumor accumulation and fast blood clearance has been employed. materials and methods in this study, the absorbed d...

Background: In radiation therapy, the peripheral dose is important when anatomical structures with very low dose tolerances are involved. In this study, the two available calculation algorithms of the Varian Eclipse 8.6 treatment planning system(TPS), the anisotropic analytic algorithm (AAA) and pencil-beam convolution (PBC) was used to compare measured and calculated peripheral dose distributi...

primary sjorgen syndrome is one of the commonest autoimmune diseases with characteristic of involvement of lachrymal and salivary glands, but other organ involvements as peripheral and central nervous system are also possible. the reported case is a 23 year old lady presented with progressive sensory ataxia and weakness of four limbs, bilateral sensory hearing loss and cognitive impairment with...

Background: Given the importance of scattered and low doses in secondary cancer caused by radiation treatment, the point dose of critical organs, which were not subjected to radiation treatment in breast cancer radiotherapy, was measured.Objective: The purpose of this study is to evaluate the peripheral dose in two techniques of breast cancer radiotherapy with two energies. Methods: Eight diff...

Introduction The purpose of this study was to estimate organ and effective doses in patients undergoing some common X-ray examinations in Sabzevar, Iran. The effective dose is one of the best parameters for describing the amount of radiation dose received by a patient undergoing any diagnostic X-ray examination. The public dose from X-ray examinations depends on various factors, and its contrib...

Introduction: Boron neutron capture therapy (BNCT) is recommended to treat the glioblastoma tumor. It is well known that neuron beams are more effective treatment than photon beams to treat hypoxia tumors due to interaction of neutron with nucleus and production of heavy particles such as 7Li and alpha particle. In this study to evaluate the suitability of BNCT for treating of ...

Background: The aim was to evaluate the benefit of technical advances for treatment planning: introduction of a hydrogel spacer, VMAT (volumetric modulated arc therapy) and a single biological organ at risk objective for the rectum and bladder. Initial standard was a step-and-shoot IMRT (intensity modulated radiotherapy) without a spacer and conventional organ at risk objectives.  Material...

Introduction: The use of electrons in the electron therapy to destroy tumoral tissue is dedicated significant contribution of different methods of radiation therapy. Scattered radiation due to exited electrons of the applicator affect the dose out of the field in the patient's normal tissue. The aim of this study is to determine the peripheral dose outside the applicator in the...
