Abstract: A self-collection device and kit that allow for self-collection of vaginal and cervical cells are provided. The device includes an intra-vaginal insertion member and a shaped collection member for collecting vaginal and cervical cells, resembling a menstrual cup.

Abstract: Disclosed herein is an optical transmitter having an analog/digital mixed-mode temperature compensation function. The optical transmitter, when detecting the optical output power of a laser diode, which outputs logic levels “1” and “0” as optical signals, through a monitoring photodiode, and controlling the bias current of a laser drive circuit to maintain the logic levels “1” and “0” at constant values, includes programs for controlling the bias current and modulation current of the laser drive circuit based on an variation in temperature, and is configured such that a temperature compensation circuit includes a digital control unit for controlling the bias current and modulation current of the laser drive circuit using the programs, so that temperature compensation operation can be adjusted only by the modification of the programs of the distal control unit.

Abstract: A system and method for providing a multimedia tone/announcement over circuit switched wireless networks are provided. The system and method enable processing of a multiple call leg function based on H.324M over a circuit switched wireless network by relaying an end-to-end H.324M initialization over the circuit switched wireless network. Therefore, a variety of multimedia services (for example, multimedia RBT/announcement service, video conferencing, etc.) together with video phone service based on H.324M in the circuit switched wireless network can be provided, which may be conducive to popularization of video phone service and realization of profits based on the provision of a variety of additional multimedia services.

Abstract: The present invention relates to new liponucleotide analog compounds having useful antiviral activity, represented by general formula (I): ##STR1## wherein R.sup.1 is a saturated or unsaturated alkyl having 6-22 C atoms; R.sup.2 is a saturated or unsaturated alkyl having 12-20 C atoms; R.sup.3 and R.sup.4 are each hydrogen or hydroxy; and B is one of the nucleoside bases of formula (a): ##STR2## wherein R.sup.5 is a hydrogen, halogen, hydroxy, amino, mercapto, or C.sub.1 -C.sub.4 alkyl amino; R.sup.6 is a hydrogen, halogen or amino; W is a nitrogen or C--R.sup.8 where R.sup.8 is hydrogen, halogen, amino or C.sub.1 -C.sub.4 alkyl, and pharmaceutically acceptable salts thereof.
