In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
Proton beam therapy has been shown to be just as effective as traditional chemotherapy, with fewer side effects and less treatment time. High-dose proton radiation could shorten breast cancer ...
Particle therapy is a form of external beam radiotherapy using beams of energetic neutrons, protons, or other heavier positive ions for cancer treatment. The most common type of particle therapy as of August 2021 is proton therapy. [1]
Anti-cancer psychotherapy – a technique [131] claiming that a "cancer personality" caused cancer, which could be cured through talk therapy (e.g. that of the Simonton Cancer Center, [132] Bernie Siegel's "Exceptional Cancer Patients" (ECaP) or Deepak Chopra). Evidence is lacking that cancer cures sold or promoted by Deepak Chopra have any value.
The Antiproton Cell Experiment (ACE), AD-4, started in 2003. It aims to assess fully the effectiveness and suitability of antiprotons for cancer therapy. The results showed that antiprotons required to break down the tumor cells were four times less than the number of protons required. The effect on healthy tissues due to antiprotons was ...
Voltage-gated proton channels are ion channels that have the unique property of opening with depolarization, but in a strongly pH-sensitive manner. [1] The result is that these channels open only when the electrochemical gradient is outward, such that their opening will only allow protons to leave cells .
The lithium-7 reaction requires a proton accelerator with energies between 1.9 and 3.0 MeV, while the beryllium-9 reaction typically uses accelerators with energies between 5 and 30 MeV. Aside from the lower proton energy that the lithium-7 reaction requires, its main benefit is the lower energy of the neutrons produced.
Proton pump inhibitors (PPIs) block the gastric hydrogen potassium ATPase (H + /K + ATPase) and inhibit gastric acid secretion. These drugs have emerged as the treatment of choice for acid-related diseases, including gastroesophageal reflux disease (GERD) and peptic ulcer disease. PPIs also can bind to other types of proton pumps such as those ...
