Medical technology helps stroke victims

Published: 10 January 2014

In order to develop preventive medications to help people at risk of brain-related diseases such as stroke, there's a need for research to understand the reaction and the respond of the brain to hypoxia. Ahmed Alrifaiy, PhD at Luleå University of Technology, in his thesis, developed measurement’s technique to enable this.

Advances in research on how the body works at biochemical level depends very much on the development of metrics that provide insight into how small organisms behave in the biomolecular level

- We have focused on hemoproteins as it has recently been shown that they can prevent the damage caused by lack of oxygen in the brain. We interconnect a plurality of metrics and a microfluidic under a microscope to examine hemoproteins effects on single neurons in the near physiological environments, that is so similar to the living as possible. Says Ahmed Alrifaiy, PhD at Luleå University of Technology.

Stress Level in neurons

It has proved to be important to find methods to study neuronal electrical signals, which is a measure of the level of stress while measuring how hemoproteins interacts with various molecules and proteins.

- Our developed system is important in order to study in real time how the brain defends itself against hypoxia. Ultimate goal is to understand how the protein works in order to develop preventive medications to help people at risk of brain cancer, stroke, Alzheimer's or Parkinson's, says Ahmed Alrifaiy.
