Review of Literature on Low-level Laser Therapy Benefits for Nonpharmacological Pain Control in Chronic Pain and Osteoarthritis

Low-level laser therapy (LLLT) is a form of light therapy that triggers biochemical changes within cells. Photons are absorbed by cellular photoreceptors, triggering chemical alterations and potential biochemical benefits to the human body. LLLT has been used in pain management for years and is also known as cold laser therapy, which uses low-frequency continuous laser…

Evaluation of pain, jaw movements, and psychosocial factors in elderly individuals with temporomandibular disorder under laser phototherapy

Few studies have been carried out on the application of laser phototherapy (LPT) for treating painful temporomandibular disorder (TMD) in elderly population that is growing worldwide. The aim of the present study was to evaluate the pain, jaw movements, and psychosocial factors in ten elderly patients with painful TMD before and after LPT. All patients…

Low-Level Laser Therapy for Treating Low Back Pain: 12-Month Follow-Up

Low back pain is the leading cause of disability, with an estimated 632 million persons worldwide suffering and producing societal costs exceeding $100 billion annually in the United States. The use of low-level lasers (LLLT) has demonstrated beneficial effects for treating a range of painful musculoskeletal conditions, including low back pain. The Food and Drug…

Hyperbaric Oxygen Therapy in Liver Diseases

Hyperbaric oxygen therapy (HBOT) is an efficient therapeutic option to improve progress of lots of diseases especially hypoxia-related injuries, and has been clinically established as a wide-used therapy for patients with carbon monoxide poisoning, decompression sickness, arterial gas embolism, problematic wound, and so on. In the liver, most studies positively evaluated HBOT as a potential…

Effect of Electromagnetic Field and Allicin as Natural Extract on Hepatocellular Carcinoma (HepG2)

Cancer is one of the major public burdens worldwide. It is a multicellular disease that can arise from all cell type. In the recent decades, the number of cancer related showed a clear elevation, in turn creating huge health and economic problems. Non-ionizing Electromagnetic Fields (EMF), from extremely-low frequency to radiofrequency, have been shown to…

Effects of pulsed electromagnetic fields on lipid peroxidation and antioxidant levels in blood and liver of diabetic rats

Levels of antioxidants in individuals with diabetes increase initially as a response to increases in reactive oxygen species (ROS) and later decrease due to reactions between free radicals and antioxidants. As the disease progresses, antioxidant mechanisms can be damaged in parallel to tissue damage, reducing antioxidant levels. Generalization should be avoided, however, due to increases…

Enhanced Liver Regeneration Following Acute Hepatectomy by Low-Level Laser Therapy

The aim of the present study was to investigate the effect of low-level laser therapy (LLLT) on liver regeneration following hepatectomy. Background: LLLT has been found to modulate various biological processes. Twelve mature male rats were used. The liver was exposed, and 70% of it was excised. The rats were assigned randomly to two groups:…

Manipulating the mitochondria activity in human hepatic cell line Huh7 by low-power laser irradiation

Low-power laser irradiation of red light has been recognized as a promising tool across a vast variety of biomedical applications. However, deep understanding of the molecular mechanisms behind laser-induced cellular effects remains a significant challenge. Here, we investigated mechanisms involved in the death process in human hepatic cell line Huh7 at a laser irradiation. We…
