How Veterinary Laser Therapy Works: MR4 ACTIVet PRO vs. High Powered Class IV Lasers


Multi Radiance Medical,

 the global leader in the development

 and manufacturing of super pulsed lasers,

 is setting the new standard for veterinary laser therapy

 with the ACTIVet PRO,

 a cordless, ultra-portable laser therapy system

 that combines high-power super pulsed lasers

 with infrared, red and blue LEDs.

 The synergistic optimization activates the entire phototherapeutic window,

 significantly reducing treatment times

 and delivering consistent, reproducible outcomes.

 The MR4 ACTIVet PRO's super pulsed laser

 produces a burst of highly focused peak power light

 at a billionth of a second.

 It's so fast with each burst

 that it eliminates overheating of the skin.

 The result is a low thermal influence on the skin

 from maximizing the dose to the target

 and the beneficial phototherapeutic effect.

 Super pulsed laser therapy is the most effective method

 to promote natural healing on both companion and equine animals.

 Clinically, it improves bone and soft tissue health,

 as well as reduces pain,

 while managing inflammation from injuries or illness.

 High-powered and high-intensity continuous wave lasers

 often penetrate poorly through the skin.

 This inefficiency overheats the superficial structures

 and negatively affects healing or worse.

 Cellular death, or apoptosis,

 can be triggered by this excessive heat

 that is not always detectable during application.

 The resulting effect on the tissue

 is no longer seen as beneficial,

 but as a negative photothermal reaction of the Class IV lasers.

 Exposing injured cells to low levels of red and near-infrared light

 activates many beneficial biological pathways,

 including cellular respiration.

 When absorbed by the mitochondria,

 the light energy helps oxygen displace nitric oxide (NO),

 an important vasodilator,

 to normalize the production of adenosine triphosphate (ATP)

 that was reduced following the injury.

 This process results in a small amount

 of reactive oxygen species (ROS)

 that activates beneficial transcription factors,

 and the cell is now able to restore normal function or initiate repair.

 Injured cells exposed to high-intensity lasers

 experience a rapid temperature increase.

 In response, heat shock proteins (HSP) begin to appear,

 and the mitochondria begin to overproduce reactive oxygen species.

 The increased oxidative stress from the combination of ROS and HSP

 results in inflammation and eventually apoptosis.

 This is not phototherapeutic, it's photothermal.

 Before any positive effect can occur,

 the light must be absorbed by the targeted tissue.

 That means the light must pass through the skin.

 The ACTIVet PRO uses multiple wavelengths that work synergistically

 to increase the overall delivery of light into the tissue.

 This not only prevents tissue overheating,

 but allows for a much lower dose.

 Higher-powered lasers such as the Class IV

 use technology that is commonly overpowered to reach the target,

 which is minimal at best,

 and also negatively generates excess heat on the skin.

 Class IV lasers often utilize a single, overpowered wavelength

 that penetrates too poorly through the skin

 to deliver an adequate amount of light at the target.

 This produces so much excessive heat

 that any beneficial effect is lost due to tissue heating.

 The Depth of Penetration Time Profile

 is the penetration of light through the tissue over time.

 Super pulsed lasers penetrate deeper

 using less energy in comparison to continuous wave,

 high-powered lasers.

 Studies show that a Class IV laser can

 only get the same result of the ACTIVet PRO

 by increasing the power over 1,600%.

 When a favorable depth of penetration time profile exists,

 less is more.

 Less energy provides more light

 and favorable depth of penetration to the target.

 Today Multi Radiance's safe, powerful, super pulsed lasers

 are the number one choice of veterinary professionals worldwide,

 more than 90 college and professional sports teams in the US and Canada,

 active and retired military healthcare facilities,

 plus tens of thousands of private practices in over 30 countries worldwide.

Top 10 Biggest Cattle Breeds In The World - Biggest Cows

Top 10 Biggest Cattle Breeds In The World - Biggest Cows To Believe .... They say size matters but does it? Well, there are different ideas on this so  let’s not discuss all of that and restrict  ourselves to cattle. Now why do people domesticate cattle? While there can be many reasons for this,  the two major are milk and meat production. Keeping this in mind, you’d OBVIOUSLY prefer  the larger breed because hello, more meat! Now before you run to get the biggest of them  all, remember that they have their own limitations  and each one is suitable to different climates  and needs. So are you ready to scrutinize the biggest  cattle breeds? Number 10. Bazadaise : This French breed of beef cattle takes its  name from the town of Bazas in the Nouvelle-Aquitaine  region of south-western France. A festival, the Fête des Boeufs Gras, is  held each year in Bazas to present fattened  Bazadaise stock. Now that’s interesting! Rising to 140cm in height and weighin

Medical calculations, part 2, Veterinary Pharmacology Hi this is dr. Herndon and this is part two of our review of medical  calculations. In this article i will be  explaining and demonstrating how to  calculate a drug dose and how to  calculate an amount of a drug that we're  going to administer to a patient. In order to be able to do these  calculations we need to know three  things: you need to know the animal's  body weight,  the drug dosage rate, and the drug  concentration. A word about the terms  dose and dosage: these two terms are often used interchangeably. It's important to know the difference, and for our purposes a dose of a drug is  what we're going to be calculating. It's  the quantity of drug active ingredient  that's delivered to a patient at one  particular time. So you'll often see a drug dose written  as 20 milligrams or 20 units. A  dosage rate, however this is something we  don't have to calculate. A dosage rate is  goi
