My primary responsibilities,
as an Associate in Surgery (Neurosurgery) [Harvard
Appointment], are in the management of a research laboratory
at MGH where I direct the Neurosurgery Surgical Research Laboratory.
I work for Dr Robert L. Martuza, Chief, MGH Neurosurgical
Service (see
Research@Neurosurgery) where I am also the Director, MGH
Neurosurgery Information Systems.
In this capacity,
I am an active member of several of standing MGH committees:
MGH Executive Committee
on Research (ECOR), Subcommittee on Research Facilities
(SRF)
MGH Subcommittee
on Research Animal Care (SRAC)
Institutional Animal
Care and Use Committee (IACUC) - Protocol Review Group (PRG)
MGH Unit Safety
Officer Advisory Committee & Laboratory Managers Committee
MGH Web Strategy
Committee - Internet, and Intranet Web Subcommittees, and
Health Care Forums Subcommittee
I have a number of
research and clinical
support responsibilities.

systems that I have setup and manage in the Neurosurgery
ORs and the Neuro Control Room. The systems
are used as the staging area for medical neuroradiology
images in planning neurosurgical cases. The micro PACS
DICOM Server - NSOR1 - is utilized by MGH PACs to routinely
push patient data sets to the Neuro OR for surgical case
planning. The systems are used for planning stereotaxic
surgery, framless stereotaxic surgery, and for OTS (optical
tracking system) neurosurgical cases as well as for other
routine neurosurgical cases involving CNS tumors, and
functional neurosurgery.

Summary
- Research Activities - Director, Neurosurgery Surgical
Research Laboratories
In the Neurosurgery
Surgical Research Laboratories, there are multiple ongoing
basic and preclinical research projects involving studies
of functional neurosurgery, neuroregeneration &
degeneration, cerebral vasospasm, stroke, neuroimaging,
neurotransplantation and gene therapy. These studies
range from basic bench-top assays of components involved
in metabolic and/or pathophysiological pathways, to
surgical models of disease pathways and treatments,
to innovative use of new technologies, to imaging studies
(PET, fCT, fMRI, 3d Doppler
Ultrasound, Optical Scanning) of physiological changes
involved in these
disease processes.
Dr
Bruce Jenkins, Director, Neurochemical Imaging
- MGH Radiology - MR
Center at MGH - fMRI, MR Spectroscopy and high
resolution anatomical studies.
A functional collaborative
scientific group centered at McLean Hospital and Harvard
NERPRC funded by the NIH/NINDS that investigates neuroprotective,
neuromodulatory and neural transplantation approaches
for PD. This work is synergistically linked in four
projects:
Project 1. A prevention
of dopaminergic degeneration induced by MPTP. Two paradigms
are tested; a) neuroprotection to reduce the loss of
dopamine terminals and b) a regeneration paradigm with
post MPTP treatment to regenerate remaining DA terminals.
Project 2. We will test
neuronal replacement by fetal dopamine cells into the
striatum, the subthalamic nucleus and the substantia
nigra in an animal model of PD. We hypothesize that
a full reinnervation with novel dopaminergic fibers
in these regions will fully restore the dysfunctional
circuitry responsible for PD.
Project 3. By generating
dopaminergic neurons from blastula stage stem cells,
we can obtain renewable cells to be transplanted for
functional tests into animal models of parkinsonism.
These stem cell derived dopaminergic neurons will be
compared in function to those derived from phenotypically
normal embryonic fetal cells.
Imaging Studies: These
projects also include a fourth core project of Imaging
Studies involving functional MRI and PET scans and analysis.

The Neurosurgery Surgical
Research Laboratory also provides surgical support facilities
for Investigators conducting studies of interest to the
Neurosurgical Service. Recent examples of studies conducted
in the Neurosurgery Surgical Research Laboratory are:

Bowel Disease & Weight Center

Albert Lee,
M.D. - Brain cooling.
Hypothermia is the most consistent, robust and
broadly applicable experimental neuroprotective
strategy for ischemic brain injury. A decrease
in stroke injury in animal models occurs with
only a 2-3 degree reduction in brain temperature.
Initial clinical reports from Germany indicate
that cerebral hypothermia can be attained by total
body cooling, and is feasible and safe in stroke
patients. We wish to test the ability of hypothermia
to block the progression of ischemic injury as
measured by diffusion-weighted MRI (DWI).
Gilberto Gonzalez,
MD, Ph.D. - Selective laser thrombolysis.
The use of thrombolytic drugs such as urokinase,
tissue plasminogen activator introduces an inherent
risk of brain hemorrhage. There is a known (0.5%)
risk in cardiac thrombolysis, it reached 6% in
the American t-PA trial. In addition, bleeding
risk excludes a number of devastated stroke patients
from thrombolytic therapy, especially post-surgical
cases. Laser assisted thrombolysis offers to improve
the access of thrombolytic drug to the clot by
causing microcavitation in the clot. This should
allow recanalization of blocked vessels with lower
doses of thrombolytic drug and lower risk of hemorrhage.
Selective laser assisted thrombolysis has been
developed for the treatment of acute myocardial
infarction by applying pulses of low enough energy
and pulse rate to selectively deposit energy in
the clot. Laser energy pulses of short duration,
nanoseconds-microseconds, deposit energy into
the thrombus and begin the ablation process before
sufficient heat diffuses to adjacent tissues,
thereby limiting thermal damage.

Don't kill

Learn from them but move on. Don't get stuck killing
dead Snakes.

Beware. Many good opportunities start as Snakes.
Coordinate the discussion to identify which items are
