LSUHS Research Core Facility:
- Laser Speckle. The CCDS recently invested in the purchase of a Perimed PeriCam PSI System. The PSI system provides the ability to non-invasively image and measure blood flow in a straightforward user-friendly manner. The imager works on the principle of laser speckle contrast analysis (LASCA) and is able to calculate flow based on movement of red blood cells. Image acquisition can be performed rapidly and instant changes in regional blood flow can be measured. The PSI system takes instantaneous measurements, has no moving parts and generates detailed images. The PSI system also uses a longer wavelength of light allowing deeper penetration into tissue providing more meaningful data collection. With access to this state-of-the-art technology, LSU Health Shreveport researchers will stand out amongst our regional academic medical center peers and the nation, while also providing a strong competitive research advantage. The PSI system is housed in newly renovated space on the 4th floor of the medical school.
- TSE Systems Stellar Telemetry. The TSE telemetry system provides the ability to measure and record blood pressure, activity, temperature (core and other locations), biopotentials (ECG, EEG, EMG, EOG, heart rate) or a combination of the parameters. Previously, the technology available on campus has only been effective for detecting gross changes in vascular pressures. The TSE system allows changes in pressure to be measured by state of the art technology, particularly when drastic changes in blood pressure are not anticipated. Researchers using the TSE system for cardiovascular research will be able to submit more competitive research proposals. The ability to monitor cardiovascular functional parameters in real time complements the impressive array of imaging technologies available on campus. The telemetry system is housed in room 4-341 on the 4th floor of the medical school.
- Mass Spectrometry Core. A comprehensive Mass Spectrometry Core is available for CCDS members that includes a Waters SYNAPT high definition mass spectrometery with two Acuity UPLC and one Acuity nanoflow liquid chromatography systems, and a Waters Micromass A-Tof mass spectrometer. These two mass spectrometers are ideal for many purposes including exact mass analysis, small molecule discovery, as well as routine peptide and posttranslational modification analysis. This mass spectrometry technology provides numerous benefits and opportunities to cardiovascular researcher on campus.
