Background: If blood donors are infected with toxoplasmosis, they often have no obvious clinical symptoms due to a healthy immune system, but the Toxoplasma is still present in their white blood cells. Blood recipients are also often people with various anemia or defective immune systems. Therefore, receiving such blood will increase the risk of infection and acute form of toxoplasmosis. The ai...
SUMMARY The current political and economic situation of Indonesia is characterised since 1999 by the transition from thirty years of autocratic leadership to a more democratic, pluralistic and open society. The reform process has already made remarkable progress in the field of human rights. The ongoing decentralisation process is a fundamental change to the political and institutional setup of...
purpose: to evaluate of proton therapy (pt) for neurosurgery patients and is also to explain the need for this system in iran. methods: a literature review was conducted (1984–2016). the strategy included a combination of keywords including proton therapy, neck, neurosurgery, brain, head, tumor, spine, arteriovenous malformation (avms), cervical and spine in database of pubmed. new generation p...
Background: The purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. Materials and Methods: Human peripheral blood lymphocytes were irradiated using proton beams (LET: 34.6 keV μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (CB) micronucleus (MN) assay. To determine th...
Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side. Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...
Unlike proton therapy, conventional radiation therapy directs X-rays not only at the tumor but also unavoidably at nearby healthy tissue. Protons deliver radiation to tumor tissue while the healthy structures will be spared during proton therapy. When protons travel through matter, secondary particles like neutrons and photons are produced. It is believed that the secondary dose can lead to sec...
Abstract Background Increasing blood supply safety is one of the most important goals of blood services in the world. In this study, we reviewed the prevalence rate and the trends of three main infections in whole blood donations and strategies for improving blood safety in Yazd blood transfusion center, Iran. Materials and Methods In this cross sectional study, data on hepatitis B, C and ...
Abstract Background and Objectives Non-alcoholic liver disease (NAFLD) is a spectrum of diseases, ranging from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH) which can lead to liver cirrhosis and hepatocellular carcinoma. Nonalchololic fatty liver is the most prevalent hepatic disorder worldwide which can affect up to the one out of four adults. Little is known about...
In the present work, the scattering differential cross section has been investigated for ion-multi electron atoms collision in the charge transfer channel. For this purpose, an active electron model was implemented and the collision process was considered as a three-body impact in the high energy range. A semi-classical formalism was used with the eikonal distorted wave function to describe the...
in order to find the susceptibility of the claisen rearrangement and next proton shift reaction of ally) aryl etherto the substiment effects in pan position, the kinetic and the:rmodynamie parameters are calculated at the33 ltp level using 6-3110. b asis set. the calculated activation energies for the rearrangements and protonshift reactions are around 3133 kcaumol and 52.16 kcal/mol, nap.. liv...
