The most common side effects include headache, high blood pressure, urinary tract infection (infection of the structures that carry urine), upper respiratory tract infection (nose and throat infection), nasopharyngitis (inflammation of the nose and throat), nausea, abdominal pain, infusion-related reactions and cyanosis (bluish discoloration of ...
Much smaller trace amounts of the short-lived protactinium-234 and its nuclear isomer protactinium-234m occur in the decay chain of uranium-238. Protactinium-233 occurs as a result of the decay of thorium-233 as part of the chain of events necessary to produce uranium-233 by neutron irradiation of thorium-232.
231 Pa makes up nearly all natural protactinium. The primary decay mode for isotopes of Pa lighter than (and including) the most stable isotope 231 Pa is alpha decay, except for 228 Pa to 230 Pa, which primarily decay by electron capture to isotopes of thorium. The primary mode for the heavier isotopes is beta minus (β −) decay.
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
The systems of the body most affected by chemotherapy drugs include visual and semantic memory, attention and motor coordination and executive functioning. [9] [10] These effects can impair a chemotherapy patient's ability to understand and make decisions regarding treatment, perform in school or employment and can reduce quality of life. [10]
The actinide series is a group of chemical elements with atomic numbers ranging from 89 to 102, [note 1] including notable elements such as uranium and plutonium.The nuclides (or isotopes) thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and (in the case of neptunium ...
However, there are side effects such as nausea, vomiting, diarrhea and constipation and, for the injectibals, injection-side irritation, injury or discomfort. Often, these are mild and serious ...
Protactinium(V) fluoride can be prepared by reacting protactinium oxide with either bromine pentafluoride or bromine trifluoride at about 600 °C, and protactinium(IV) fluoride is obtained from the oxide and a mixture of hydrogen and hydrogen fluoride at 600 °C; a large excess of hydrogen is required to remove atmospheric oxygen leaks into the ...
