Doctors administer sclerotherapy by injecting a sclerant (a sterile chemical which irritates the vein lining) into your vein causing it to close and eventually be reabsorbed into the body. To compensate for the loss of the vein, blood circulation is re-routed through healthy veins.
Abstract. 1  Metaplastic breast cancer (MBC) is a rare subtype of invasive breast cancer that tends to have an aggressive clinical presentation as well as a variety of distinct histologic designations. Few systemic treatment options are available for MBC, as it has consistently shown a suboptimal response to standard chemotherapy regimens.
Chromatography is a collection of laboratory techniques for separating a mixture of substances. These techniques involve passing the mixture from a mobile phase to a stationary phase. Each substance in the mixture does this at a specific rate, causing it to become separated as it moves into the stationary phase.The retardation factor (RF) is the relative amount of time that a particular substance spends in the mobile phase.ach substance in the mixture does this at a specific rate, causing it to become separated as it moves into the stationary phase.
