  2. Blood irradiation therapy - Wikipedia

    en.wikipedia.org/wiki/Blood_irradiation_therapy

    Traditional medicine. Alternative diagnoses. v. t. e. 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 ...

  3. Pathogen reduction using riboflavin and UV light - Wikipedia

    en.wikipedia.org/wiki/Pathogen_reduction_using...

    White blood cells – due to the effective inactivation of white blood cells in donated blood products, riboflavin and UV light treatment may be used as an alternative to gamma-irradiation for the prevention of transfusion-associated graft-versus-host disease (TA-GVHD), [7] a serious blood transfusion related complication.

  4. Near-infrared window in biological tissue - Wikipedia

    en.wikipedia.org/wiki/Near-infrared_window_in...

    The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. [1] Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused ...

  5. Irradiation - Wikipedia

    en.wikipedia.org/wiki/Irradiation

    Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation, for a variety of purposes. [1] Irradiators may be used for sterilizing medical and pharmaceutical supplies, preserving foodstuffs, alteration of gemstone colors, studying radiation ...

  6. Light therapy - Wikipedia

    en.wikipedia.org/wiki/Light_therapy

    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.

  7. Infrared - Wikipedia

    en.wikipedia.org/wiki/Infrared

    Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with waves that are just longer than those of red light (the longest waves in the visible spectrum ), so IR is invisible to the human eye.

  8. Platelet - Wikipedia

    en.wikipedia.org/wiki/Platelet

    Platelet. Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] Platelets have no cell nucleus; they are fragments ...

  9. Bacterial motility - Wikipedia

    en.wikipedia.org/wiki/Bacterial_motility

    Bacterial motility is the ability of bacteria to move independently using metabolic energy. Most motility mechanisms that evolved among bacteria also evolved in parallel among the archaea. Most rod-shaped bacteria can move using their own power, which allows colonization of new environments and discovery of new resources for survival.
