Four different purified hyaluronidases have been approved for use in the United States, three of animal origin and one recombinant. They are indicated as adjuvants in subcutaneous fluid administration for achieving hydration, for increasing the dispersion and absorption of other injected drugs, or for improving resorption of radiopaque agents, in subcutaneous urography.
Hydrogen oxidation is coupled to the reduction of electron acceptors such as oxygen, nitrate, ferric ion, sulfate, carbon dioxide (CO 2), and fumarate.On the other hand, proton reduction is coupled to the oxidation of electron donors such as ferredoxin (FNR), and serves to dispose excess electrons in cells (essential in pyruvate fermentation).
Thallium(III) acetate is the acetate salt of thallium, with the chemical formula Tl(CH 3 COO) 3.As a selective culture medium in microbiology, [1] thallium acetate is toxic, [2] but it can also be used as a hair loss agent.
The remnants of the Empire retreated here after their defeat at Endor, reforming into the First Order – as well as, secret even to the First Order, Darth Sidious' Sith forces reconstituting on Exegol. Western Reaches – the sectors once controlled by the Republic that border the Unknown Regions of the galactic "west". Essentially similar to ...
Hydrogen cyanide (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N.It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).
Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of HIV/AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.
ASE is produced when a laser gain medium is pumped to produce a population inversion. Feedback of the ASE by the laser's optical cavity may produce laser operation if the lasing threshold is reached.
99m Tc-MDP must be prepared in a radiopharmacy.It is usually supplied as a "cold kit" to which radioactive 99m Tc from a generator is added. Kit composition may vary between suppliers, but contents typically includes medronic acid, stannous chloride dihydrate and sometimes ascorbic acid. [4]
