Abstract:

Cells and non-human transgenic animals have been engineered to be deficient in the gene encoding agouti-related protein (AgRP). AgRP deficient transgenic animals have a reduced day time respiratory quotient (RQ), indicating that AgRP is involved in the regulation of energy metabolism, resulting in the reduced usage of fat as an energy source. These AgRP deficient transgenic animals can be used to select for and test potential modulators of AgRP. This data allows for methods of screening for AgRP modulators which regulate energy metabolism and caloric utilization. The disclosure also relates to a NPY/AgRP double knockout mouse which can be used to select for and test potential modulators (e.g., agonists or antagonists) of AgRP and/or NPY.

Abstract:

A rotameter system adapted to produce an output indication that is linearly proportional to flow. The primary element of the system includes a float contained in a variable area tube through which flows the fluid to be measured, the float being raised or lowered in the tube as a function of flow rate, and a bar magnet mechanically coupled to the float and axially movable therewith. The secondary element of the system includes a rotatable follower magnet magnetically coupled to the bar magnet and a pointer mounted on the shaft of the follower magnet whereby the pointer sweeps from zero to maximum along a scale as the float travels from its low to its high position. A mass is eccentrically mounted on the shaft of the follower magnet, the position of the mass relative to the shaft axis being adjusted to produce a moment compensating for the non-linear relationship between flow rate and pointer movement.
