Neutron capture therapy NCT is based on the ability of the non-radioactive isotope boron to capture thermal neutrons with very high probability and immediately to release heavy particles with a path length of one cell diameter.

Boron Neutron Capture Therapy BNCT is a radiation science which is emerging as a hopeful tool in treating cancer, by selectively concentrating boron compounds in tumour cells and then subjecting the tumour cells to epithermal neutron beam radiation. The most exclusive property of BNCT is that it can deposit an immense dose gradient between the tumour cells and normal cells. BNCT integrates the fundamental focusing perception of chemotherapy and the gross anatomical localization proposition of traditional radiotherapy. There is an increase in oral cancer burden day by day. The mainstream treatment modalities in treating cancer are surgery, chemotherapy and radiotherapy.

Boron carbide enriched with 10 B isotope 10 B 4 C was synthesized by simple and low cost solvothermal method. Structural, morphological and optical analysis has been done. Hexagonal phase of the synthesized material show emission in visible region and makes it a promising material for cancer diagnosis. Cytotoxicity analysis has been done to analyze its suitability for biomedical applications. This is a preview of subscription content, access via your institution.

Neutron capture therapy of cancer

Boron neutron capture therapy BNCT is a selective radiation treatment for tumors that preferentially accumulate drugs carrying the stable boron isotope, 10 B. BNCT has been evaluated clinically as an alternative to conventional radiation therapy for the treatment of brain tumors, and more recently, recurrent advanced head and neck cancer. Here we investigated the effect of BNCT on prostate cancer PCa using an in vivo mouse xenograft model that we have developed. We compared xenograft growth among these groups, and the body weight and any motility disturbance were recorded. The in vivo studies demonstrated that BPA-mediated BNCT significantly delayed tumor growth in comparison with the other groups, without any severe adverse events. There was a significant difference in the rate of freedom from gait abnormalities between the BPA-mediated BNCT group and the other groups.

Since its first description, boron neutron capture therapy BNCT was a special type of radiotherapy for treatment of cancer and with focus mainly on glioma therapeutic. This procedure requires the selective accumulation of boron into the tumoral cells, and due to this requirement, different boron-enriched compounds have been designed and developed. Efforts to circumvent the selectivity-uptake challenge and other problems, such as solubility, stability, and toxicity, have been to driving force behind the medicinal chemistry field in boron-based compounds. In this regard, a wide diversity of medicinal chemistry hypothesis has been used to obtain new and efficient potential BNCT-glioma drugs. In this chapter, these ideas are analyzed focusing on their medicinal chemistry characteristics. Glioma - Contemporary Diagnostic and Therapeutic Approaches. He hypothesized that if boron could be selectively concentrated in a tumoral tissue and then exposed to a neutrons beam, a higher radiation dose to the tumor relative to surrounding normal cells would result.

Бринкерхофф поднялся со своего места, словно стоя ему было легче защищаться, но Мидж уже выходила из его кабинета. - Руки на стол, - бросила она через плечо.  - Когда я уйду, пожалуйста, никаких глупостей.

Он поднял глаза на видеомониторы, и у него закружилась голова. Одна и та же картинка смотрела на него со всех двенадцати мониторов наподобие какого-то извращенного балета. Вцепившись руками в спинку стула, Бринкерхофф в ужасе смотрел на экраны. - Чед? - услышал он голос у себя за спиной. Обернувшись, Бринкерхофф начал всматриваться в темноту.

Скажите, что вы согласны на его условия. Нам нужен этот шифр-убийца, или все здесь провалится сквозь землю. Все стояли не шелохнувшись. - Да вы просто с ума все сошли, что ли? - закричал Джабба.

Перечень этой бесценной информации был нескончаем. Всяческие вторжения, способные повредить американской разведке, абсолютно исключались. Конечно, офицеры АНБ прекрасно понимали, что вся информация имеет смысл только в том случае, если она используется тем, кто испытывает в ней необходимость по роду работы. Главное достижение заключалось не в том, что секретная информация стала недоступной для широкой публики, а в том, что к ней имели доступ определенные люди. Каждой единице информации присваивался уровень секретности, и, в зависимости от этого уровня, она использовалась правительственными чиновниками по профилю их деятельности.

 Ладно, - нахмурилась Сьюзан.

 - Хочу его запатентовать. - Как торговую марку? - Беккер смотрел на него изумленно. Парень был озадачен.

Она чувствовала, как к ее горлу подступает тошнота. Его руки двигались по ее груди. Сьюзан ничего не чувствовала. Неужели он ее трогает.

Джабба схватил калькулятор и начал нажимать кнопки. - А что это за звездочка? - спросила Сьюзан.  - После цифр стоит какая-то звездочка. Джабба ее не слушал, остервенело нажимая на кнопки.

Подумайте. Это не лишено смысла.

    The boron neutron capture therapy (BNCT) has been utilized for cancer treatment from last decade, where chemotherapy and radiation have.

    Neutron capture therapy NCT is a nonsurgical therapeutic modality for treating locally invasive malignant tumors such as primary brain tumors , recurrent head and neck cancer , and cutaneous and extracutaneous melanomas.
