For example, every battery has two terminals, and its voltage is the potential difference between them. Keep in mind that whenever a voltage is quoted, it is understood to be the potential difference between two points. Biotechnology and Bioengineering published by Wiley Periodicals, Inc.Īleem, I. Drive Pure Expressions Dual Channel Electric Breast Pumps are ON SALE NOW. The familiar term voltage is the common name for electric potential difference. The upregulation of Bmp2 and Spp1 expressions induced by ES could be one of the mechanisms behind the electrically stimulated osteogenesis.īone regeneration electrical stimulation faradic by-products macrophages preosteoblasts. This study shows that macrophages could respond to ES and potentially contribute to the bone formation alongside preosteoblasts. However, cell proliferation was impaired by the excessive current density from the electrodes, and also faradic by-products in the case of macrophages. This expression is called the electric field at position P P ( x, y, z) of the N source charges. Osteogenic differentiation of preosteoblasts was not observed during the early stage of ES as the level of Runx2 expression remains unchanged. Were IV/R with I being the current in Amps, V being the voltage in Volts and R being the resistance in Ohms. It is also found that Spp1 expression of macrophages was partially enhanced by faradic by-products. Answer (1 of 2): I believe you may be referring to Ohms law. When quality and commitment come first, our results speak for themselves. The upregulation of Bmp2 and Spp1 messenger RNAs was observed after 3 days of stimulation, which is consistent among two cell types. Kings Electric Services is a leading provider of commercial electric services. electric field, an electric property associated with each point in space when charge is present in any form. It is found that pH of the culture media was not significantly changed, whereas the average hydrogen peroxide concentration was increased by 3.6 and 5.4 µM after 1 and 2 hr of ES, respectively. This study aims to investigate the responses of macrophages (J774A.1) and preosteoblasts (MC3T3-E1) to ES and the faradic by-products from ES. However, its mechanism is still being investigated and discussed. The capability of electrical stimulation (ES) in promoting bone regeneration has already been addressed in clinical studies.
