Abstract: A Y-zone treatment device using a pulse-controlled LED, presented in the present invention, comprises: a Y-zone treatment unit, which generates an LED light for female Y-zone treatment at the position of a female Y-zone area; and a driving control unit for controlling the driving of the Y-zone treatment unit, which generates the LED light for female Y-zone treatment at the position of the female Y-zone area, and controlling pulse width by pulse width modulation (PWM) for driving of the Y-zone treatment unit, and thus the female Y-zone can be treated with light emission of an LED in the female Y-zone area by wearing the device on the female Y-zone area, and the temperature can be controlled by means of pulse width control of PWM.

Abstract: A composition for delivering a drug includes a drug carrying liposome carrying a drug in a liposome, and an empty liposome which does not carry the drug and includes phospholipid having a head and two fatty acid chains, wherein both of the two fatty acid chains comprises omega-3 fatty acids or their derivatives.

Abstract: Disclosed herein are simple and unique methods of methods of preparing liposomal compositions of N-(4-hydroxyphenyl) retinamide (4HPR) and/or other retinoids. Also disclosed are liposomal 4HPR compositions prepared by such methods, and use of such compositions in the treatment of diseases, such as breast cancer. This invention further provides methods for improving the efficacy of N-(4-hydroxyphenyl) retinamide (4HPR) as a chemopreventive agent in the presence of agents that potentiates its ability increase the expression of inducible nitric oxide synthase (iNOS, and NO production in cells.
