Helium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions. [1] Helium's first ionization energy of 24.57 eV is the highest of any element. [2]
Most of these gases are drugs, including oxygen. [2] Many other gases, collectively known as factitious airs, were explored for medicinal value in the late eighteenth century. In addition to oxygen, medical gases include nitric oxide (NO), and helium-O2 mixtures (Heliox). Careful considerations and close monitoring needed when medical gases are ...
A cancer vaccine, or oncovaccine, is a vaccine that either treats existing cancer or prevents development of cancer. [1] Vaccines that treat existing cancer are known as therapeutic cancer vaccines or tumor antigen vaccines. Some of the vaccines are "autologous", being prepared from samples taken from the patient, and are specific to that patient.
Preventive or prophylactic vaccines; Treatment or therapeutic vaccines; These vaccines are intended to treat existing cancer by stimulating the patient’s immune system. [3] Cancer vaccines can also divided into specific or universal cancer vaccine based on the types of cancer it is used for.
NeuVax has been tested as adjuvant treatment in nearly 200 breast cancer patients over a total of 5 years, and has shown to be safe and effective in Phase 2 trials. [6] As a result, two additional NeuVax trials registered or underway are: (1) a 700 patient Phase 3 trial for FDA approval - not yet recruiting [2] [needs update] and (2) a 300 patient Phase 2 trial studying the combination of ...
Putin said in televised comments that "we have come very close to the creation of so-called cancer vaccines and immunomodulatory drugs of a new generation". "I hope that soon they will be ...
The vaccine, designed to train the immune system of patients to recognize and attack specific mutations in cancer cells, earlier showed promise in treating melanoma in a mid-stage study ...
High-pressure nervous syndrome (HPNS – also known as high-pressure neurological syndrome) is a neurological and physiological diving disorder which can result when a diver descends below about 500 feet (150 m) using a breathing gas containing helium. The effects experienced, and the severity of those effects, depend on the rate of descent ...
