Abstract: A phototherapy device (100) and a phototherapy instrument (500), comprising a near infrared irradiation module (110) used for emitting near infrared light to the head, and a control component (120) used for controlling the operation of the near infrared irradiation module (110) and coupled to the near infrared irradiation module (110). A method for using near infrared light for therapy, which comprises applying a first, optional second, optional third or more near infrared lights to the head of a patient. The device and method are used for treating Alzheimer's disease, improving brain mitochondrial function and ATP levels, promoting amyloid beta protein (A?) decomposition, reducing A? deposition, reducing damage to nerve cells, improving nerve tissue repair and regeneration capabilities, improving cognitive ability etc. A therapy method using the phototherapy device (100) or the phototherapy instrument (500), and a computer readable recording medium controlling required near infrared light.

Abstract: The present invention provides methods and systems for performing in vivo flow cytometry. In one embodiments, selected circulating cells of interest of a subject are labeled with fluorescent probe molecules. The labeled cells are irradiated in-vivo so as to excite the fluorescent probes, and the radiation emitted by the excited probes is detected, preferably confocally. The detected radiation is then analyzed to derive desired information, such as relative cell count, of the cells of interest. In some embodiments, the circulating cells comprise apoptotic cells whose detection can allow, e.g., non-invasive monitoring of the efficacy of a cancer treatment, such as an anti-tumor or an anti-angiogenic therapy.
