Methods are provided for treating or preventing conditions comprising hypertension and dyslipidemia using antihyperlipemic agents and compounds that antagonize the angiotensin II type 1 receptor, function as partial or full activators of peroxisome proliferator activated receptors and lower triglycerides or elevate blood HDL-cholesterol. The regulation circuit only comprises a first resistive pair to sense the common-mode voltage at the differential input terminals, a second resistive pair to force the voltage across the load to a predetermined value, and an active device coupled between the junction points of the first and the second resistive pairs. The substrate holding mechanism and the polishing table are operable to provide relative movement between the surface of the substrate and the polishing surface while the substrate holding mechanism presses the surface of the substrate against the polishing surface to thereby polish the surface of the substrate. The wedge-shaped member extends in a radially asymmetrical manner around the liquid discharge passage. The result is a combined in-phase bit and a combined quadrature bit for each bit position in the datastream.
