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.

Clinical support 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:

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.

If you see a Snake, kill
the Snake. Don't form Snake
review committees. Don't form Snake

Don't kill dead Snakes.
Leave them alone, they are dead. Learn
from them but move on. Don't get stuck
killing dead Snakes.
Observe & Beware. Many
good opportunities start as Snakes.
Coordinate the discussion to identify
which items are Snakes and
which are real opportunities.
