Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It's quite disgusting that this information is not available from every stroke association and doctors group.
My back ground story is here:

Shear sensitive nanocapsule drug release for site specific inhibition of occlusive thrombus formation

Maybe your doctor can use this to remove the blood clots inside your blood vessels.

BACKGROUND Myocardial infarction and stroke remain the leading causes of mortality and morbidity. The major limitation of current antiplatelet therapy is that their effective concentrations are limited due to bleeding complications. Targeted delivery of antiplatelet drug to sites of thrombosis would overcome these limitations.
OBJECTIVES Here, we have exploited a key biomechanical feature specific to thrombosis; significantly increased blood shear stress due to a reduction in the lumen of the vessel, to achieve site directed delivery of the clinically used antiplatelet agent eptifibatide using shear-sensitive phosphatidylcholine based nanocapsules.
METHODS 2.8x10(12) PC based nanocapsules with high dose encapsulated eptifibatide were introduced in microfluidic blood perfusion assays and in in vivo models of thrombosis and tail bleeding.
RESULTS Shear-triggered nanocapsule delivery of eptifibatide inhibited in vitro thrombus formation selectively under stenotic and high shear flow conditions above 1,000 s(-1) shear rate while leaving thrombus formation under physiological shear rates unaffected. Thrombosis was effectively prevented in in vivo models of vessel wall damage. Importantly, mice infused with shear sensitive antiplatelet nanocapsules did not display prolonged bleeding times.
CONCLUSIONS Targeted delivery of eptifibatide by shear-sensitive nanocapsules offers site specific antiplatelet potential and may form a basis for developing more potent and safer antiplatelet drugs. This article is protected by copyright. All rights reserved.
