Research nursing staff and study physicians are responsible for medical aspects of the outpatient portion of research studies.
CTRAL is located on the main Texas A&M campus and is readily accessible with easy parking for study participants and staff.
RECRUITMENT & COMPLIANCE CORE
The recruitment core of CTRAL is responsible for recruiting hospitalized, outpatient, and healthy volunteers alike. CTRAL PIs currently have successful research collaborations with many physicians in the area at medical centers such as:
- College Station Medical Center
- Baylor Scott and White Medical Center
- CHI St. Joseph Health
- M.D. Anderson in Houston
Our experienced Compliance Core staff ensure that CTRAL activities are in compliance with IRB, IACUC, biosafety, environmental, health safety, and other federal regulations.
HUMAN RESEARCH SUPPORT CORE
A metabolic kitchen (commercial grade) is available 24.7 for food, test diet, food supplement, and non-hazardous oral compounding (USP 795) preparations for human subjects.
Our experienced staff is available to ensure appropriate use of stable isotope technology in human subjects. Our lab is available to facilitate STAT blood/tissue processing and is equipped with:
- 2 biosafety cabinets.
- 2 centrifuges.
- A blood cell counter.
- A high-density secured data archive system.
- A secured, controlled, monitored sample. storage/biobank with a CO2-backup system and emergency power for 9 -80°C freezers with the capacity to store 250,000 samples.
- Clinical waste management in a decontamination room for reusable tools/instruments used in human subjects.
- Soil and waste autoclave for sterilizing clinical waste.
COMPOUNDING CORE
A controlled/monitored USP797 certified clean room with 4°C and 20°C storage unit, for clinical preparations for IV compounding of non-hazardous stable isotope infusate compounding and a sterilizer for clinical tools and instruments.
This facility can also be utilized for preparing aseptic syringes and infusion bags on clinical test days. Sterility and pyrogenicity of prepared IV compounded infusates are tested according to USP 797 guidelines and the standard operation protocol for the operating pharmacist.Our experienced staff is available to ensure appropriate use of stable isotope technology in human subjects.
FUNCTION CORE
Major function equipment and facilities are available, including:
- NO breath analyser (NIOX),
- 4 FEV1 analyser (SpiroD)
- Handgrip dynamometer (Vernier)
- MicroRPM – MIP/MEP to measure mouth pressures (Carefusion)
- Resting energy expenditure using ventilated hood (ParvoMedics True One 2400)
- EKG (Nasitt Cardio System)
- Heart Rate Monitors for exercise (Polar E600)
- Pedometers (Sportline Model 370)
- Exercise bikes (Schwinn)
- Leg press (Nebula)
- Exercise bikes – Watt Measurement (Sport Excalibar)
- Bench press (Nebula)
- Smith press (Life Fitness)
- Stress test treadmills for graded exercise testing (VO2 max)
- KinCom machine
- Resistance endurance and resistance rehabilitation training facilities with whole body workout circuit machines (leg extension/curl, squat, latissimus pulldown, chest press, bicep curl, tricep extension)
- 8 different thera-bands with resistance of 20-30%
We measure body composition using the following techniques:
- Deuterium/bromide dilution technique: Each subject consumes a pre-weighed oral dose of D2O and sodium bromide after which both total body and extracellular eater will be estimated from deuterium dilution and bromide space through measuring the D2O {Mahsut, 2011, 351-353}{Walker, 2015, 838-843} and Br- levels in plasma or urine.
- In addition, body composition at the whole-body level and within body compartments (extremities, trunk) are measured by means of a DXA system (Hologic QDR 4500 W with Apex Software), thereby measuring fat tissue, lean tissue, and bone mineral content.
This is also measured using Bioelectrical Impedance Analysis (BIA) D550 (Impedimed).
ANIMAL RESEARCH CORE
