It is necessary to accumulate the B atoms selectively to the tumor cells for effective boron neutron capture therapy (BNCT). In order to achieve accurate measurements of B concentrations in biological samples, we employ a technique of neutron capture autoradiography (NCAR) of the sliced whole body samples of tumor bearing mice using CR39 plastic track detectors. The CR-39 detectors attached wit...

Benign notochordal cell tumors (BNCTs) are tumors originating in the axial skeleton, where chordomas occur. Although very rare, some cases of extraosseous chordoma, such as in the soft tissue and lungs, have been reported. We report a case of a primary tumor showing the notochordal characteristics of BNCTs within the axial skeleton.An asymptomatic 57-year-old woman presented with an abnormal sh...

Undifferentiated thyroid cancer (UTC) is a very aggressive tumor with no effective treatment, since it lacks iodine uptake and does not respond to radio or chemotherapy. The prognosis of these patients is bad, due to the rapid growth of the tumor and the early development of metastasis. Boron neutron capture therapy (BNCT) is based on the selective uptake of certain boron non-radioactive compou...

In order to investigate the possibility of using the T.R.R beam tubes in BNCT, it is necessary to select the best one from three north beam tubes. This beam tube should have more flux and better spectrum compared to others. So, after simulation of the last configuration of reactor’s core (NO.55) by MCNP4C code, the neutron flux and spectrum were calculated at the start, middle, and end of each ...

نوترون تراپی با بور یا bnct یک روش موثر در درمان انواع تومورها به خصوص تومورهای مغزی است. اساس این روش بمباران ناحیه تومور نشاندار شده با بور-10 توسط نوترون های با شدت و انرژی مناسب است. ذرات ناشی از واکنش جذب نوترون در هسته های بور، انرژی خود را در ناحیه ای قابل مقایسه با ابعاد سلولی تخلیه کرده و باعث نابودی آن می شوند. در این رساله طیف انرژی نوترون راکتور مینیاتوری اصفهان mnsr برای bnct بهین...

Some recent studies in Italy have focused on the possibility of exploiting clinical high energy electron linear accelerators, normally used in photon radiotherapy, as photo-neutrons source for in-hospital neutron medical applications. In-Hospital photo-neutron radiotherapy extends the possibilities of Boron Neutron Capture Therapy (BNCT) to external treatment of diffused tumors when other metho...

10B-enriched L-p-boronophenylalanine (BPA) is one of the compounds used in boron neutron capture therapy (BNCT). In this study, several variations of nuclear magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI) were applied to investigate the uptake, clearance and metabolism of the BPA-fructose complex (BPA-F) in normal mouse kidneys, rat oligodendroglioma xenografts, and rat ...

The uptake of (10)boron by tumor cells plays an important role for cell damage in boron neutron capture therapy (BNCT). CD133 is frequently expressed in the membrane of glioma stem cells (GSCs), resistant to radiotherapy and chemotherapy, and represents a potential therapeutic target. To increase (10)boron uptake in GSCs, we created a polyamido amine dendrimer, conjugated CD133 monoclonal antib...
