Leukaemia could be treated with blasts of plasma

Blasts of electrically charged gas could provide a new treatment for leukaemia.

Scientists have found that cancer cells from leukaemia sufferers are killed when they are exposed to a type of matter known as cold plasma.
These streams of ionised gas, similar to the material found inside decorative plasma balls and plasma televisions, are thought to trigger the in built self destruct mechanism in the cancerous cells while healthy cells remain unscathed.
The researchers now believe it will be possible to develop a dialysis style treatment where the blood of leukaemia is patients is passed through plasma streams to destroy the cancer cells.
Professor Mounir Laroussi, director of the laser and plasma engineering institute at Old Dominion University in Norfolk, Virginia, said: “Leukaemia is the most common childhood malignancy and accounts for approximately one out of three cancers in children
“Although there is a lot of fundamental scientific work that needs to be done, but one can imagine a machine similar to the one used for dialysis where the blood undergoes treatment by low temperature plasma.”

The researchers, whose work is published in the scientific journal Journal of Physics D: Applied Physics by the Institute of Physics, exposed the leukaemia cells to a four minute blast of plasma. The cells died around 12 hours after being treated.
Other scientists have previously proposed using streams of plasma to kill off viruses such as the common cold.
It is thought the cold plasma produces highly reactive molecules that interact with the cancer cells.
As the cancer cells take up more molecules from the blood than healthy cells, the researchers say they will be more effected by the plasma and will die.
The researchers now plan to do more work to see how healthy red and white blood cells are effected by the plasma to ensure it will not have any toxic effects if used as a treatment.
Professor Laroussi added: “Cancer cells multiply rapidly and therefore are much more likely to take up the reactive species (molecules) generated by the plasma.
“Our next steps are treating healthy cells and comparing them to the effects on cancerous cells. “

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to
believe that I was supporting praying to change the weather. So, when
I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group
or religion, or any other stupid article, it does not mean that I
support them. It just means that it is important for all human beings
to know about them. Common sense, which is usually very good among our
readers, is good enough to understand that. When, like in the recent
articles on drug decriminalization, it is necessary to make it
clearer, I add a comment, which in this case was very clear: I support
decriminalizing all drugs, as it is stupid to throw depressed and sad
people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is
any change to the Message which says clearly that we must not use any
drug except for medical purposes. The same applies to the freedom of
expression which must be absolute. That does not mean again of course
that I agree with anti-Jews, antisemites, racists of any kind or
anti-Raelians. But by knowing your enemies or the enemies of your
values, you are better equipped to fight them. With love and respect
of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to
the death your right to say it".
