This restorative component of NIR therapy has interesting implications for slowing disease impacts and even some aspects of aging. Vitamin D formation: Vitamin D is a type of vitamin that needs not to be consumed from food. “We started irradiating damaged cells in cultures and found what appeared to be a ‘sweet spot’ in terms of dosage,” says Janis Eells, UWM professor of biomedical sciences who studies how NIR light helps to slow degenerative eye disease. 6. The exposure to UV light is called as photo-therapy. Otto creates promotional material, engages with media, and writes articles about the University, generating content in the areas of science, technology, commercialization, and architecture. Enwemeka, who is internationally known for his work in phototherapy, is one in a cluster of scientists at UW–Milwaukee (UWM) conducting studies in this emerging field of medicine. What about airport baggage also? Sorry, this clip is not currently available, Chemical warfare during the First World War. This is a kind of communication technology in which data can be transmitted at a speed of 10kbit/s. A mammalian cell contains thousands of mitochondria, protein “machines” in charge of converting the energy in the food we eat into a form of chemical energy that the cell can use. “[We use] only certain wavelengths, at a certain intensity, for a certain amount of time.” Studies show that though red to near-infrared light covers wavelengths of about 600 to 1100 nanometers (nm), the 670 nm and 830 nm wavelengths are the most beneficial of the near-infrared (NIR) spectrum. Thank You for the refresher of information in microbiology and ultraviolet. UV light in the sun is key for the formation of Vitamin D. Thus the formed Vitamin-D helps the storage of calcium in the bones and thereby strengthen them. To trap insects: Insect trap instruments have UV light emitters. She says that it is a concept that makes perfect sense, when you consider that “mitochondria are similar to chloroplasts in plants, which absorb red and blue wavelengths of light and use the light energy to make chemical energy [during] photosynthesis.”, Eells, who has great admiration for the complex ways in which mitochondria behave and communicate with the rest of the cell, says that these organelles do far more than simply produce energy for cells. In contrast to far-red and NIR light which stimulate the body’s repair of injured cells, blue light improves wound healing by killing the bacteria that cause wound infections. Determining the best wavelength for phototherapy is a difficult task, says Jeri-Anne Lyons, a UWM associate professor of biomedical sciences. For any light therapy to work, there must be light-responsive molecules within the body that are positively altered in some way by the light waves’ energy. Among Enwemeka’s discoveries in phototherapy research: blue light in a certain wavelength kills the antibiotic-resistant “superbug” form of Staphylococcus aureus. Eells has seen this kind of restoration in her own work treating eye diseases like retinitis pigmentosa and diabetic retinopathy. NIR light—which produces no heat—is administered through an array of light-emitting diodes (LEDs) that can be configured to the desired wavelength. One explanation is that bacteria contain light-sensitive, iron-rich molecules that, upon absorbing blue light, generate free radicals that kill the bacteria. Additionally, the stage is set for another imbalance: over-production of free radicals. This saves us from the harmful effect of UV light from the sun. Thus these instruments can keep insects away from us. What if chronic injuries could be healed with the application of something as ubiquitous as light? For details go through sterilization methods. Near-infrared light can help restore balance by activating antioxidant molecules that “disarm” the free radicals and help repair and even reverse their damage. What if there was a way to treat debilitating diseases without drugs or surgery? “If you can tone down the inflammation in a non-healing wound, like a pressure ulcer, you speed the healing.”. Thanks for asking eh ! UV radiation has enough energy to kill the microbes and also destroys the organic debris and carbon monoxide. Visible light can be used for signalling thorough the VLC (visible light communication). This UV stream kills microbes present on human surfaces  while entering the concerned rooms. “But suppose that the [tissue] layer is thick,” says Enwemeka. Because light in these wavelengths can penetrate the skin and be absorbed by subcutaneous cells, it can act on wounds, internal injuries, and disease. Chukuka S. Enwemeka, dean of UWM’s College of Health Sciences, conducts an experiment with research associate Violet Bumah. “We are conducting dose-response experiments now to determine the optimal dose of light.”, Last year, Eells and a team of collaborators conducted a wound-healing study in spinal cord injured veterans who, because of being bedridden and inactive, developed pressure ulcers, or bedsores, that wouldn’t heal. It can cause chemical reactions and make other substances to a florescence. An accumulation of too many creates what’s called “oxidative stress” and will damage other components of the cell, such as proteins and DNA. White light lies between ultraviolet radiation and near red and infrared radiation. But given its relative ease of application, blue light therapy holds tremendous promise as an alternative to full-spectrum antibiotics, many of which are decreasing in efficacy. His team is exploring the fact that one of the downstream effects of blue light therapy could be the activation of genes responsible for division of mammalian cells. The goal is to achieve complete bacterial eradication in a wound. Finding the appropriate dose and dose regimen for delivering the light is important. Humans are exposed to so many antibiotics—through food sources and careless use of prescribed medications—that bacterial resistance is now rising much faster than the rate of new drug discovery. “Through this enzyme [cytochrome c oxidase], the light gives a ‘molecular kick’ to the mitochondria, telling the cell to turn on a large number of antioxidant and energy-boosting genes,” summarizes Eells. Enwemeka demonstrated that one dose of blue light irradiation killed as much as 92% of two pervasive MRSA strains. It is present in sunlight and can also be produced by electric arc lamps. Conducted at the Zablocki Veteran Affairs Medical Center in Milwaukee, the study compared the rate of wound healing in two groups of veterans with similar ulcers. The spectrophotometers employ UV light to detect and measure the concentration of a given sample in liquid form.

The exposure to UV light is called as photo-therapy. Could they be used on cruise ships on incoming bags to stop viruses from entering the ships? I saw a unit being used down the aisle of an airliner to cleanse the inside of the plane instead of spraying. Besides these certain plant extracts and chemicals are stained or have inherent dyes that make them detectable when kept in the UV environment. Enwemeka’s current project with UWM physicist Valerica Raicu aims to render that question moot. When the skin of a baby is exposed to light for long periods, the bilirubin in the skin breaks down to water-soluble form and gets out of the body through urine. Research by Karu and others has shown that when cytochrome c oxidase, an enzyme that is part of the energy-generating sequence in the mitochondria, is excited by photons of NIR light, a number of cellular changes can occur. In limited numbers, free radicals play important roles in cell communication. In 1945 my parents had a floor lamp that had a ultra violet bulb and a timer and you wore sunglasses. Known as phototherapy, the use of light in medical treatment is producing surprisingly successful results in the treatment of a variety of ailments from topical infections and chronic wounds to autoimmune and chronic degenerative diseases, says Chukuka S. Enwemeka, dean of the University of Wisconsin–Milwaukee’s College of Health Sciences. For example, there is an increase in the messages exchanged between mitochondria and the cell’s nucleus resulting in a boost in the mitochondria’s output of ATP, a molecule that increases the cell’s energy. However, these molecules have a dark side. This includes phototherapy experiments that help researchers better understand the cellular processes involved. My parent used it on my sister and me. So employing a UV light source can help purify the air around. This means this radiation has greater energy than normal visible light. But it cannot be seen with naked eyes unlike visible light. Laura L. Otto is a senior writer in the Division of University Relations and Communications at the University of Wisconsin–Milwaukee. Hence when the substances are exposed to UV light at predefined wavelength and time, there will be effective sterilization. Wisconsin People & Ideas is the Academy's quarterly magazine of contemporary Wisconsin thought and culture. I can not remember what it was used for. In recent research, Enwemeka found that in higher doses, treatment with blue light yielded a completely unexpected result: While some human cells are destroyed by irradiation along with much of the bacteria, a greater percentage of human cells appear to multiply. But only one group was subsequently given phototherapy three times a week for ninety seconds for four weeks. “In that case, you have to increase the dosage [to reach all the bacteria]. It seems too simple for people to accept,” says Lyons. The genes activate release of antioxidants and other cell-protecting factors that counteract cell degeneration by repairing mitochondria that have become damaged or dysfunctional. These lamps are installed safely to keep anyone from being exposed t… According to the study, the rate of healing was 250% faster in the wounds receiving the NIR light. A description of the position of visible light in the electromagnetic spectrum and a look at medical uses of visible light.

Blue light therapy has achieved undeniable laboratory results in treating antibiotic-resistant MRSA. For this, the sample is put in a UV chamber and observed. It’s something Enwemeka and his colleagues at UWM are determined to accomplish. In a 2007 study supported by Dynatronics Corporation, Enwemeka discovered that some wavelengths of blue light, especially those in the 405–470 nm wavelength, kill bacteria so effectively that the process even works on MRSA, the antibiotic-resistant “superbug” form of Staphylococcus aureus. In Medicine: For certain skin diseases like psoriasis and other skin conditions, the prolonged exposure to UV light is better therapy. Medical uses of visible light A description of the position of visible light in the electromagnetic spectrum and a look at medical uses of visible light. PDT is an alternative to surgery for cancer in which the patient is given drugs to make them sensitive to light before a laser is aimed at the area to be treated.
