Abstract: A cell treatment solution and a method that is used for preparing a stained cell suspension that is provided to a measurement of nuclear DNA by flow cytometry. The cell treatment solution may include a surfactant, RNase, and a fluorescent dye. The surfactant may include, for example, a non-ionic surfactant, a zwitterionic surfactant, an anionic surfactant, and/or a cationic surfactant. In one method of the presently disclosed subject matter, stained cell suspension that is provided to a measurement of nuclear DNA by flow cytometry is prepared. The method may include adding a tissue sample to a cell treatment solution including a surfactant, RNase, and fluorescent dye, disaggregating the tissue sample, and filtering the disaggregated tissue sample. Another method of the presently disclosed subject matter includes disaggregating a tissue sample, preparing cell suspension by filtering the disaggregated tissue sample, and adding a cell treatment solution including a surfactant, RNase, and fluorescent dye.

Abstract: A body temperature maintaining apparatus is used on occasion of emergent transportation, utilizing an air conditioner of an emergent transportation vehicle or the like. The body temperature maintaining apparatus includes a heat receiving part for receiving heat of an air blown from an air conditioner mounted on a mobile body for carrying a patient, a heat applying part attached to a living body part of the patient thereby to apply the heat, a tube body which interconnects the heat receiving part and the heat applying part for feeding a heat medium from the heat receiving part to the heat applying part, and a forcibly moving unit provided in at least one of the heat receiving part, the heat applying part, and the tube body, and adapted to forcibly move the heat medium from the heat receiving part to the heat applying part.

Abstract: While remarkably reducing the botheration and burden on the subject, an apnea/hypopnea condition can be detected correctly and easily, and the type of the condition can be identified. A detecting apparatus for detecting an apnea/hypopnea condition of a living body, includes: an electric current applying electrode section to supply an electric current via electrodes into a cervical region of the living body; a measurement electrode section to measure an impedance of the cervical region by the electric current; an analysis section which detects an apnea/hypopnea condition based on the measured impedance; and an output section which outputs the result of detection.

Abstract: A cuff includes: a belt-like body which is adapted to be wrapped around a desired region of a living body; a fixing portion which is provided in the body, and which is configured to fix the body in a state where the body is adapted to be wrapped around the region of the living body; a pressurizing portion which is provided in the body, and to which a fluid pressure is to be supplied to be inflated to pressurize the region of the living body; and an ultrasonic transmissive portion which is provided in the body, and through which an ultrasonic wave for observing a tissue in the region of the living body is transmissible.

Abstract: An apparatus for evaluating a vascular endothelial function, includes: a cuff pressure controlling unit configured to perform continuous pressure stimulation on a part of a body of a subject for a predetermined time, by using a cuff adapted to be wrapped around the part of the body of the subject; a cuff pressure detecting unit configured to detect a cuff pressure from an output of a pressure sensor connected to the cuff; a pulse wave detecting unit configured to detect a pulse wave from the output of the pressure sensor; and an analyzing unit configured to evaluate the vascular endothelial function by comparing vessel viscoelastic indexes which are obtained from the pulse wave detected in two of zones before, during, and after the pressure stimulation, and which exclude an amplitude of the pulse wave.

Abstract: A method of processing first and second signals obtained by measuring a medium, to obtain a pulse wave signal and an artifact signal which are separated, includes: separating vectors of the first and second signals by using a separation matrix into a vector of the pulse wave signal and a vector of the artifact signal, the separation matrix including a norm ratio of a stable zone of the pulse wave signal and a compensated norm ratio of an artifact zone.
