Re: [Therapeutic-Laser_Therapy] Lasers: Visible light pulses knock out viruses in blood

Ruby this is very interesting,
I didn't read it very throughly because I feel lousey.
 
When you mentioed the homopathic remedies I have some and I have tried them .
In the past they worked some on grief when I had to have a cat put to sleep.
I think now I may be over stimulated because I do take a stimulte to stay awake or I would just sleep all the time.
 
Today I have not hardly been out of bed from having fatigue and flu like and I have the worst herpes rash on my tailbone .
 
I use to get this almost constant.  A few little blisters would break out and then when they were drying up new ones would form.
That had been much better until late yesterday afternoon.
I have used my godzilla machine with the AC and DC and placed the electrodes at different locations on one side of my body and I am heading back to the bed to do the other side.
 
My daughter gets married this Sat.  I have to go to Lexington Ky on Fri and I don't feel like I am up to going to her wedding unless I can get this under control   I know I will go but I just feel physically worse since yesterday.
 
I have done some searches for greif treatments and found some therapys that I didn't know about.
 
I finally got a appt with a psychologist that is trained in EMDR.
It must be a very effective therapy but that one lady would not treat me because she thougth I was to unstable.
 
I promise you I have never been dangerous or harmful to anyone but in the past I have been sucidle a few times when I had bad depression and then when this lyme has been so bad that all I did was sleep day in and day out.
 
 
Now I have a fear of death in a different way that I have never known.
 All these feelings that I have had since my brother Randy died are so new to me.
I just can't explain just how deep they are and what it was like to know that my worst nightmare had happened.
 
I don't know if I should say it like that I have my daughter and husband and I love them both very much but I can't measure how deep this pain is like it has on bottom.
 
To add to that the way things were at his house was something that made it so horrible that my words cannot get enough feeling out to describe how it felt to see where he laid for three days but it was just so much blood and it looked like him.
 
Almost like seeing a ghost in blood.   THen I saw the blue jeans he had on the day he died they were in the floor with his belt in them.
He cried and told me he was afraid he was going to die.
I had to leave when he said that becasue I had tried so hard to help him and he would not try to help his self.
 
But really the drinking didn't do it I think the Hep C and the shots of  interferon even if the autopsey didn't show his liver was bad .
 
THat interferon causes deep depression and that was when he got worse with drinking and self pity and that was not who he was.
 
I pray so much now .  I read the bible and get more c onfused not knowing how to understand what I am reading.
 
So often I think people tell me what they think I want to hear.
I know that I will never know in this life and God is the only one that knows about anyone.
 
But it would be so hard to be in heaven without my brother and some of the other people that I love.
 
We had this dog that we got back in 1991 and a couple of weeks ago we had to put him to sleep he was so much a part of our lives and I can't let myself think about him.
Our cat is not far from being put to sleep.  She is around 14 and lives at the barn. 
I have the most sensitive heart I use to cry over dead dogs on the side of the road.
 
It does not feel good to be so sensitive.  My brother would have never grieved over me like I have him.
 
I pray to feel better but I do have so much to be thankful for.
Feeling good is not something I can put a price on.
 
I don't know if you have been very sick but it seems now over half my life has been like that.
 
Thanks for all the information you have sent me.
I want to learn more about these lights but I do know that it is over my head.  I would like to learn more about     CES or maybe get a brain tuner .

Visible light pulses knock out viruses in blood

13:28 27 July 2007
Viruses lurking in biological samples could be killed off with an intense pulse of visible light, new research shows.
Scientists in the US say the technique seems to have significant advantages over alternative methods, including use of UV irradiation or microwaves, as it kills viruses more effectively and safely.
The technique destroys a virus with a pulse of light from a low-power laser. The pulse produces mechanical vibrations in the virus shell, or capsid, irreversibly damaging and disintegrating it, and so "deactivating" the virus for good. The technique might be used to kill HIV, as well as hepatitis C, say the researchers involved.
Traditional methods of destroying viruses, such as UV irradiation, can cause mutations, which eventually make the micro-organisms resistant. UV light can also damage the DNA of surrounding healthy cells.
Scientists have also tried using microwaves to kill viruses but this is even less promising since the water in and around a micro-organism strongly absorbs this frequency of light. Most of the energy from the microwave radiation is absorbed by the water and does not even reach the virus itself.
Human cells undamaged
Kong-Thon Tsen of Arizona State University, and colleagues at Johns Hopkins School of Medicine, and the Uniformed Services University of The Health Sciences, all in the US, found that visible light can overcome this problem.
The researchers applied pulses of purple-coloured light lasting just 100 femtoseconds (10-15 seconds) to viruses called M13 bacteriophages. It takes just a single pulse to destroy the viruses completely, say the researchers.
The "power density" of the laser is just 5 microjoules per square centimetre, which is low enough to leave surrounding human cells and tissue undamaged, but high enough to produce large-amplitude vibrations in a virus's capsid. It is also too low to cause genetic mutations, meaning the virus will not build up resistant to the treatment over time.
Disinfecting blood
Tsen told New Scientist that the technique could be used to disinfect blood or other biological samples in hospitals.
"In addition, we believe that the method may be especially important in designing novel treatments for blood-borne viral diseases," he said. "For example blood dialysis allows us to irradiate a patient's blood outside the body and potentially cleanse it of infectious virus particles before reintroducing it into the patient. In this way, we could reduce mortality associated with diseases like hepatitis C and AIDS."
The team now plans to test the efficacy of its technique in killing a wide range of deadly viruses, including HIV and hepatitis C. "We also plan to conduct further tests on the effects of the low-power visible laser on mammalian cells to determine any potential side effects and confirm that it selectively kills viruses," said Tsen.

Viruses Killed by Light Pulses

In another biophysics breakthrough, new research indicates that pulses of visible light from a laser can be used to destroy viruses in biological samples, such as blood. According to reports, the visible light is actually more effective at disrupting the virus' structure than traditional eradication methods, such as UV or microwave irradiation. These other forms can also trigger mutations within the viruses, perhaps generating resistances.
The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. It ranges in wavelength from approximately 400 nm (4 x 10-7 m) to 700 nm (7 x 10-7 m). It is also known as the optical spectrum of light.
The wavelength (which is related to frequency and energy) of the light determines the perceived color. The ranges of these different colors are listed in the table below. Some sources vary these ranges pretty drastically, and the boundaries of them are somewhat approximate as they blend into each other. The edges of the visible light spectrum blend into the ultraviolet and infrared levels of radiation.
Most light that we interact with is in the form of white light, which contains many or all of these wavelength ranges within them.

Shining white light through a prism causes the wavelengths to bend at slightly different angles due to optical refraction. The resulting light is, therefore, split across the visible color spectrum.
This is what causes a rainbow, with airborn water particles acting as the refractive medium. The order of wavelengths (as shown to the right) is in order of wavelength, which can be remembered by the mneumonic "Roy G. Biv" for Red, Orange, Yellow, Green, Blue, Indigo (the blue/violet border), and Violet. You'll notice that in the image and table Cyan is also appears fairly distinctly, between green & blue.
By using special sources, refractors, and filters, you can get a narrow band of about 10 nm in wavelength that is considered monochromatic light. Lasers are special because they are the most consistent source of narrowly monochromatic light that we can achieve.

Abstract. We demonstrate for the first time that, by using a visible femtosecond laser, it is effective to inactivate viruses such as bacteriophage M13 through impulsive stimulated Raman scattering. By using a very low power visible femtosecond laser having a wavelength of 425 nm and a pulse width of 100 fs, we show that M13 phages were inactivated when the laser power density was greater than or equal to 50 MW cm-2. The inactivation of M13 phages was determined by plaque counts and depended on the pulse width as well as power density of the excitation laser.
