Laser treatment is being engaged for several applications including wound healing, bone repair, pain-relief, etc. The basic principle of optical maser therapy relies on the absorption of photonic energy by molecular photoacceptors (chromophores), leading to a photochemical reaction. This photochemical reaction results in the generation of Reactive oxygen Species (ROS) and heat, which are known to play a crucial role in laser-induced damage. This study explores the role of item heat in affecting laser-induced damage. By using the formula, H = ms (H being Heat, M being stack S being Specific heat, and being change in temperature), it was speculated that a change in special heat would affect rise in temperature and hence cytotoxicity induced by the laser. Therefore, the ad hoc heat of different solutions was metric using a calorimeter-like setup. Once the specific heat of different solutions was determined, cells (HaCaT, compassionate Skin Epithelial Cells and NOKSI, Normal Or al Keratinocytes) were treated with solutions of varying specific heat capacities and assessed in laser damage. It was observed that in lowering the specific heat by using various cell culture solutions, in that location is a sharp increase in temperature at lower laser doses, leading to increased damage to cells.Further, a robotic branch is being assembled to qualify the heat dispersion during clinical therapy, with the aim of mimicking manual operator establish motions and helping simulate clinical therapy in further lab experiments. entreThere are three primary phases of wound healinginflammation, create from raw material formation, and tissue regeneration. It is a dynamic, interactive process involving soluble mediators, blood cells, extracellular matrix, and parenchymal cel... ...of glycerol is indeed cytotoxic.When treating the cells with a 1.7W laser, the 10% FBS solution proved to be the most effective in preserving cell viability, due to its high specific heat capaci ty. Future goals of this experiment pass on strive to determine whether the laser-induced putting to death is through heat, Reactive Oxygen Species (ROS) generation, or some other factor. In Aim 2, we were able to capture the precise clinical operator movements in multiple dimensions using the precision 6-axis sensor. We recently completed construction of our robotic arm and are in the process of programming using the clinical info captured with the sensor. This robotic arm concept is expected to greatly stabilize the laser motions, and will certainly be a beneficial and revolutionary application in not only lab experiments, but also experiments dealing with animals, such(prenominal) as mice.
