Abstract: The present invention relates to a pharmaceutical composition comprising an inhibitory peptide against Fas signaling as an active ingredient for prevention or treatment of obesity, fatty liver, or steatohepatitis. Binding specifically to Fas, which is extensively expressed in the liver and adipose tissues in an obese state, the inhibitory peptide against Fas signaling exhibits high delivery rates to inflammatory regions caused by obesity and directly inhibits the Fas signaling, which is a main inflammation signaling pathway, to inhibit an inflammatory response. Therefore, the peptide can be advantageously used for alleviating or treating obesity, fatty liver, or steatohepatitis.

Abstract: A process mechanically breaks colloidal suspension bonds with the surrounding fluids through high energy impact with a stationary plate or a colliding fluid stream. The fluid with a colloidal suspension is pumped through one or more ?? to 3? nozzles to collide with either a stationary plate in an impact chamber at high velocity, or another similar or different fluid stream. The process breaks the bonds maintaining the colloidal suspension, disassociates these materials, and allows for gravity or chemical separation of the previously colloidal particles from the fluid. The process can separate colloidal particles from a liquid medium through pressurization followed by high energy impact and rapid release.

The flowmeter assembly includes a coil driver for providing a drive current to a coil assembly, an electrode for measuring an electrical signal created by the conductive fluid flowing through a magnetic field created by the coil assembly, and a micro-processor for controlling the magnetic flowmeter.

The micro-processor then modifies the frequency of the coil driver in response to the fluid's electrical conductivity to optimize the sampling rate of the flowmeter. The flowmeter assembly modifies the coil driver frequency by either increasing the drive frequency for highly conductive fluids or decreasing the drive frequency for less conductive fluids.
