Energy Radiation And Its Effect On The Cells

The word laser is an acronym for, “Light Amplified by Stimulated Emissions of Radiation”, this means that all the lights in a laser have the same wavelength. Within a century of the laser being invented it occupied a major role in scientific research, medicine, industry, and even daily life. Lasers are used in the medicine field for procedures such as, laser eye surgery, heart, stomach, and intestinal surgeries. These procedures laser procedures are said to be harmless. Major factory industries use lasers to cut many things ranging from thin

In photodynamic antimicrobial chemotherapy (PACT), a combination of a photoresponsive agent and visible light causes selective destruction of microbial cells such as bacteria, fungi and viruses (Dougherty et al., 1998; Kalka et al., 2000; Konan et al., 2002). A number of studies have shown PACT to be highly effective in the in vitro destruction of viruses and protozoa, as well as Gram-positive and Gram-negative bacteria and fungi. The ability of visible light-photosensitising agent combinations to kill microorganisms has been known for over 100 years. PACT is an abbreviation and scientific term that stands for Photodynamic Antimicrobial Therapy. Photodynamic Antimicrobial Therapy (PACT) has been used effectively in medicine since the 1990s for the treatment of tumours, skin diseases and wound infections. The fungal cells, unlike human cells possess a cell wall. This cell wall is stained with a special photosensitizing gel-dye that is harmless to human cells but selectively makes fungi sensitive to a specific wavelength of light and means the bacteria and nail fungus is destroyed. PACT is used as an effective

Red light does not belong to the ultra-violent range of light and you receive exposure to it through specially designed beds. NASA developed this technology that delivers this light

According to Cameron, laser therapy increases collagen production and decreases inflammation, while hindering bacterial growth. It also promotes vasodilation so that blood and other nutrients are able to flow into the area. One indication for

The therapeutic properties of light have a long history. The ancient Indians discovered, in 1,000 BCE that light therapy, in addition to psoralens, a plant compound, could cure vitiligo (Barr, H. et al., 2002). In the early 20th century, Niels Finsen’s and his wife’s treatment of lupus vulgaris with ultra-violet light notably earned them the Nobel Price (Barr, H. et al., 2002). A more modern application of light’s theraputic properties is photodynamic therapy. Photodynamic therapy destroys tumours through the use of a photosensitizer, oxygen, and light in a wavelength specific to the photosensitizer (Brown & Ibbotson, 2009, p. 251; Barr, Kendall, Reyes-Goddard & Stone, 2002, p. 136). First, the photosensitizer is administered (Brown & Ibbotson,

Laser beams of different intensities are used for destroying the cells that cause the hair growth.

Adamantidis 2015). It enables tunable manipulation of cell phenotypes using light (Jay & Barkin 2014). The technique employs a set of microbial ion channels and pumps that activate upon stimulation by particular wavelengths of light. After transgenic expression within neurons, these type I opsins permit optical modulation of membrane depolarisation or hyperpolarisation with temporal precision on the order of milliseconds (Snowball & Schorge 2015). The delivery of genes that encode proteins capable of conveying light sensitivity to neurons has provided a tool that may overcome some of the limitations of traditional neuromodulation techniques (Henderson et al. 2009). Srivats et al designed a method to optogenetically stimulate and inhibit acute pain in both normal and pathological states in freely moving nontransgenic mice by intrasciatic nerve injection of adeno-associated viruses encoding an excitatory opsin enabled light-inducible stimulation of acute pain, place aversion and optogenetically mediated reductions in withdrawal thresholds to mechanical and thermal stimuli upon transdermal delievery of optical stimuli. Techniques such as this, which eliminate the need for surgical implantation of stimulation devices, will obviously have a tremendous impact on the speed with which optogenetic therapy can

Laser therapy includes the use of monochromatic light emissions that are powered by a low power laser. It can be used as a treatment for many medical conditions including chronic pain, musculoskeletal injury, some wounds, and more. These types of therapy encourage the natural healing process in the body.

This paper was written with the purpose to inform people of the uses of Low Level Laser Therapy as well as provided insight on the potential of this technology. This includes misconceptions and facts, healing of both external and internal wounds and the reduction of pain. Some knowledge over lasers and cells will be necessary to understand this paper. My sources are both secondary and tertiary sources composed of scholar journals and internet articles as well. In order for the reader to understand the terms in this paper, key terms will be provided and a glossary as well in the end of the paper.

The ability or capacity to do work, according to Feyman, Leighton and Sands (2013), may be thought of as energy. Energy is a ubiquitous substance that is not necessarily tangible but can be easily detected. For example, electrical energy, chemical energy, light, heat, nuclear energy and mechanical energy are all forms of energy; yet, the ability to define each as a physical material can be relatively difficult. To continue, energy can neither be created nor destroyed but exists in two forms – potential and kinetic. Feyman et al. (2013) reported that potential energy is the capacity for doing work based upon the body’s position in space. In this situation, an object will have a certain amount of potential energy based upon its location in reference to a gravitational field. This notion is true in and outside of Earth, given that the movement of objects are influenced by Newton’s laws of motion (Feyman et al. 2013). In comparison, kinetic energy is the amount of energy a body possesses due to its motion. As such, the concepts of potential and kinetic energy are relatively different; however, they are closely intertwined and each influences the other (Rowlands 2015). With that being said, the purpose of this paper is to perform a critical analysis of potential and kinetic energy. A comparison will be drawn between each type of energy, in conjunction with their unique differences. This paper will be concluded by discussing one real-world application that is directly related to

The laser is used in the medical production for analysis and treat certain defects in the body, because the laser beam is so minor and precise, it makes easier for medics to treat tissue without damaging the neighbouring area of the tissue, a laser is used in the following list techniques

Prior to Starion’s laser tissue welding breakthrough, the most common electrosurgical tool was the monopolar device, also known as the Bovie device. With

Laser stand for Light Amplification by Stimulated Emission Radiation, unlike a standard light beam, is a source of monochromatic, coherent and unidirectional light. Lasers are installed widespread in everyday life across multiple numerous applications like CD & DVD, barcode scanners, entertainment, welding or cutting in industry, aid to fire control or alignment of roads and tunnels. In the medical field, lasers are diagnostic and therapeutic instruments that offer a whole range of solutions. The laser which enables for greater surgical precision is less invasive and promotes healing time or cure. This technique is generally much less traumatic than traditional surgical techniques. The first use of lasers in medicine was to damage the retina to understand ocular injury due to accidental exposure [1]. Since the first ruby laser, several devices have been improved placing ophthalmology at the forefront of medical specialties using this technology. The laser has also many applications in the

Biophotonics has turned into the extraordinary expansive term for all methods interrelated with natural things and photons. Biophotonics alludes to discovery, reflection, emission alteration, absorbtion, and formation of radiation from cells, organic entities, biomolecular, tissues and, biomaterials. In this tittle, we will look focused around medicinal fields and its application territories.
