Transcript of Nanotechnology Improving Neurology

Enhancing Neurology with Nanotechnology
Although current techniques are better than jumping into operations, there are still some complications that arise from the different imaging techniques;
Current Imaging Techniques
SPECT
CT
MRI
PET
"So what's the problem, Doc?"
Radiation
Radiation
Requires CT and X-ray Assistance for Accuracy
Trending research in Neurology:
Brain Tumors
Currently there are only a handful of treatment options for patients with brain tumors;
Radiation
Surgery
Chemotherapy
"Let's Talk about Your Treatment Options"
Surgery
Chemotherapy
Radiation
Therapy
Diarrhea
Hair loss
Nausea / Vomiting
Trouble
Swallowing
Urinary and
bladder changes
Infertility in
Women
Lymphedema
Joint Pain
Fatigue
Sores in Mouth
and Throat
Burning Pain
Motor Disability
Tingling/Loss
of feeling
Persistent Headache
Blood Disorders
Difficulty Hearing
Fits
Speech
Problems
Personality
Changes
Poor
Coordination
Weakness
Depression
Infection
Seizure/
Stroke
...and these are their
possible side effects
Outline
Imaging
Treatment
Regeneration

Neurology:
(n) the branch of medicine or biology that deals with the anatomy, functions, and organic disorders of nerves and the nervous system.
Neurologists:
(n) a medical specialist in the nervous
system and the disorders
affecting it
Central Nervous System:
(n) the part of the nervous system which consists of the brain and spinal cord
electrical impulses are transmitted
coordination of entire nervous system
Unusable with
pacemakers
and metallic
implants

(this is no small matter)
Silicon Nanoparticles and Sound Waves
Using ultrasound to look for disease
The goal:
Use silicon instead of radioactive contrast solutions
Use sound waves instead of x-rays
The Positives:
Doesn't find cancer by causing cancer
People with prosthetic limbs/pacemakers can be accurately tested too

The Cool Thing about Nanoparticles
can make nanovescicles that act like liposomes
no lasers necessary (damages healthy cells)
BXQ-350 nanovesicle
The Problem with Getting Medicine
to the Brain
the Blood Brain Barrier: a filtering mechanism that blocks the passage of foreign contaminants (including medicines)
day 5
day 27
day 72
only attacks tumor cells
bypasses Blood Brain Barrier
What about traumatic brain/CNS injuries?
MIT and the University of Hong Kong Lee Kai Shing Department of Anatomy
made a peptide solution that repaired a blind hamster's vision
"peptide nano-mesh"
Have a great Vacation! (good luck if you have more finals)
