Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps) and in Russia (in all variants).
Pathogen reduction using riboflavin and UV light is a method by which infectious pathogens in blood for transfusion are inactivated by adding riboflavin and irradiating with UV light. [ 1 ] [ 2 ] [ 3 ] This method reduces the infectious levels of disease-causing agents that may be found in donated blood components, while still maintaining good ...
The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines.
In medicine, photopheresis (aka extracorporeal photopheresis or ECP) [1] is a form of apheresis and photodynamic therapy in which blood is subject to apheresis to separate buffy coat (WBC + platelets) from whole blood, chemically treated with 8-methoxypsoralen (instilled into a collection bag or given per os in advance), exposed to ultraviolet light (UVA), and then returned to the patient.

Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.
Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms. UVGI primarily inactivates microbes by damaging their genetic material, thereby inhibiting their capacity to carry out vital functions.
Blood vessels break, the lower layers of the skin get damaged, and blood pools, forming a blister. • Heat blisters can form after a burn or sunburn, Dr. Patel says, and blisters can occur when ...
The process begins when UV exposure triggers an increase in blood levels of urocanic acid (UCA), which possesses the unique ability to cross the blood-brain barrier. Upon entering the brain, UCA initiates a cascade of biochemical reactions that promote glutamate biosynthesis, particularly in critical regions such as the motor cortex and ...
