AMRIS Admin• Part of the McKnight Brain Institute

• Operates as a core facility to UF investigators as well as supports the NHMFL external user program

• Under federal CAS we set fees to break even--we currently do not include amortization of MRI/S systems

• Salaries: $560,000 + Expenses: $400,000 = $960,000 budget

• NHMFL support (2009): $350,000 (direct); UF faculty pay their own fees from other grants and cover the rest of the budget

• $100k of NHMFL money budgeted to equipment/upgrades and $250k budgeted to instrument time and consulting fees for the external user program and pilot studies

• Currently we budget $5,000 per external user or pilot project

• NHMFL provides additional $200,000 to fund three development cores headed by Art Edison, Steve Blackband, and Glenn Walter

• UF provides matching support for development cores

• Starting in 2010 NHMFL will provide 0.5 FTE for Barbara Beck (RF engineer)

• 3T Operator: Joy Kidder

• 3T Engineer: Dave Peterson

• RF Engineers: Barbara Beck, Dave Peterson

• NMR applications: Jim Rocca

• Spectrometer maintenance and scheduling: Dan Plant

• Spectrometer maintenance: Kelly Jenkins

• Animal Imaging applications: Huadong Zeng will be

starting December 1st

• *Pulse programmer

• *Imaging data processing

* Need to build up

AMRIS/NHMFL Technical Staff

All of these staff members are partially supported by NHMFL funds through hourly fees, either as consultants or through instrument fees.

• All instruments have user fees. We must cover all costs without

making a profit.

• Current fees are posted on the AMRIS web site:

• http://www.mbi.ufl.edu/facilities/amris/

• Most “routine” service jobs can be handled by AMRIS staff

• New development or very sophisticated applications are done in

collaboration with expert faculty groups

• We budget for approximately 40 external user projects and 10 pilot

studies

******************************* “The maglab's 1-mm NMR probe was the key technology that enabled us to identify the mating pheromone in C. elegans. I consider this the most important discovery from my lab in the past decade.” Paul SternbergThomas Hunt Morgan Professor of Biology and HHMI, Caltech

*******************************We are working on “the settlement cue for Phestilla nudibranchs that eminates from coral. We have worked on this project for over 10 years and have made more progress in the last two years than we ever did before that. This is due to the ability to get NMR data in the 1-mm probe on tiny amounts of highly bioactive material.”  Dr. Valerie Paul, Head Scientist, Smithsonian Marine Station*******************************

Low-E MAS Probe

Now available for external users

Optical and magnetic resonance imaging track labeled stem cells within the bone marrow of mice following femoral arterial delivery of bone marrow stem cells. The bone chamber window allows for the optical tracking of transplanted cells prior to high resolution MRI and does not interfere with MRI signal acquisition or have a negative impact on the image quality of MR images.

Tibia Window w/ MRI micro-coil for Confocal and MRI Imaging

Ultrahigh resolution in vivo MR images obtained following the arterial delivery of labeled bone marrow cells. Images are reconstructed at a resolution of 21x21x38 μm3 and were acquired in 90 minutes. Dashed red circles indicate areas of image contrast attributed to single cells in both the muscle and the bone marrow. The dashed green circle highlights an area with accumulation of labeled cells. The green legend (line) in A is 150 μm.

• Pending– 7T/30 cm animal imager proposal: NIH ARRA HEI

– 700 MHz NMR for proteins proposal: NIH ARRA HEI

– AMRIS facility HVAC and layout renovation

NIH ARRA Limited Competition: Core Facility Renovation, Repair, and Improvement (G20)

– Helium recovery proposal with UF Physics, High B/T: NSF Academic Research Infrastructure Program: Recovery and Reinvestment (ARI-R2)

– 950 MHz and 36T console projects previously described

Renovation of the AMRIS Facility

Current facility is 12 years old and at capacity. Any new instruments could not currently be housed in the AMRIS wing

Specific Aim 1: Reconfigure internal walls within the AMRIS wing to allow addition of new instruments.

Specific Aim 2: Renovate HVAC support and cryogen delivery within the AMRIS facility Air handling systems have also improved since the construction of the AMRIS wing.

Specific Aim 3: Provide centralized animal staging for imaging and spectroscopy studies

AMRIS plans moving forward• Maintain existing overall general external user

program at about the current levels (slight increase).

• Continued development under 3 technical cores with

faculty leaders to better grow unique areas of

strength.

• Build the RF core strengths and continue integrating

with Tally RF group. Priorities: – Large volume coils

– Multi-nuclear coils

– Better 1H coils/probes for imaging at 750 MHz

– Better live animal capabilities
