1. Illustration of electrophoresis. 2. Illustration of electrophoresis retardation. In chemistry, electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field. As a rule, these are zwitterions.
Mechanisms of action. While increased skin permeability is seen through sonophoresis, the precise mechanisms to describe sonophoresis are yet to be fully discovered. However, there are several important mechanisms that have been identified that contribute to the phenomenon of sonophoresis.
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.
Syphilis ( / ˈsɪfəlɪs /) is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. [1] The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). [1] [2] The primary stage classically presents with a single chancre (a firm ...

Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries. These lesions may lead to narrowing of the arterial walls due to buildup of atheromatous plaques. [9] [10] At onset there are usually no symptoms, but if they develop, symptoms generally begin ...
Phosphorus is an essential mineral for humans listed in the Dietary Reference Intake (DRI). Food-grade phosphoric acid (additive E338 [104]) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. The phosphoric acid also serves as a preservative. [105]
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their activities.
Moving-boundary electrophoresis was developed by Arne Tiselius in 1930. [3] Tiselius was awarded the 1948 Nobel Prize in chemistry for his work on the separation of colloids through electrophoresis, the motion of charged particles through a stationary liquid under the influence of an electric field.
An Aloka SSD 3500 ultrasound machine. Phonophoresis, also known as sonophoresis, is the method of using ultrasound waves to increase skin permeability in order to improve the effectiveness of transdermal drug delivery. This method intersects drug delivery and ultrasound therapy.
