* Follicle-stimulating hormone or FSH (Gonal-F®, Follistim®): FSH works much like hMG. It causes the ovaries to begin the process of ovulation. These medicines are usually injected.
* Gonadotropin-releasing hormone (Gn-RH) analog: These medicines are often used for women who don’t ovulate regularly each month.

Protecting medical-imaging systems and equipment can extend equipment life, reduce costs, and increase patient-care levels.

Hospitals and imaging centers invest millions of dollars in complex, sophisticated medical-imaging equipment that is highly sensitive to power problems and fluctuations. According to Michael Stout, engineering manager of Falcon Electric (Irwindale, Calif), medical-imaging systems are “a system of interconnected scanners, sensors, computers, distributed data-storage devices, and networking devices.” Adds Mike Habibi, technical support manager of MGE UPS Systems (Costa Mesa, Calif), these systems are very sensitive to electrical noise, power shortages and glitches, and brownouts.
