Specialty. Ophthalmology. Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria .
Narcotics Anonymous ( NA ), founded in 1953, describes itself as a "nonprofit fellowship or society of men and women for whom drugs had become a major problem." [1] Narcotics Anonymous uses a 12-step model developed for people with varied substance use disorders [2] and is the second-largest 12-step organization, [3] after 12-step pioneer ...
Sonophoresis. Sonophoresis also known as phonophoresis, is a method that utilizes ultrasound to enhance the delivery of topical medications through the stratum corneum, to the epidermis and dermis. Sonophoresis allows for the enhancement of the permeability of the skin along with other modalities, such as iontophoresis, to deliver drugs with ...
Electrophoresis is the basis for analytical techniques used in biochemistry for separating particles, molecules, or ions by size, charge, or binding affinity. [10] In principle, electrophoresis is used in laboratories to separate macromolecules based on charge. [11] The technique normally applies a negative charge so proteins move towards a ...
Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl).
There are 20 isotopes of sodium ( 11 Na), ranging from 17. Na to 39. Na (except for the still-unknown 36 Na and 38 Na), [4] and two isomers ( 22m. Na and 24m. Na ). 23. Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2).
Iontophoresis. ICD-9-CM. 99.27. MedlinePlus. 007293. [ edit on Wikidata] Iontophoresis is a process of transdermal drug delivery by use of a voltage gradient on the skin. [1] [2] Molecules are transported across the stratum corneum by electrophoresis and electroosmosis and the electric field can also increase the permeability of the skin.
Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na 2 S 2 O 5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent. [2]
