Successful cryopreservation of human ovarian cortex tissues using supercooling

The development of new method to cryopreserve human ovarian cortex tissues without damage is needed for the improvement of quality of life (QOL) of female cancer patients. Here we show novel cryopreservation method of human ovarian cortex tissues by using supercooling (S.C.) procedure. Our method will be helpful in order to preserve fertility of female cancer patients

A therapeutic method for the direct reprogramming of human liver cancer cells with only chemicals

Various methods for the direct reprogramming of human somatic cells have been developed. However, a therapeutic method to reprogram and eliminate human solid tumor cells has not been developed. Here we show a novel therapeutic method to reprogram and eliminate human solid tumor cells with chemicals. This therapeutic method may be applicable to various human solid tumor cells that express aldo-keto reductase family 1 member B10 (AKR1B10) and retinoid X receptors (RXRs)

Underlying Assumptions and Designated Verifier Signatures

In this paper, we define an underlying computational problem and its decisional problem. As an application of their problems, we propose an efficient designated verifier signature (DVS) scheme without random oracles (related to symmetric pairings). We formally redefine the (Strong) Privacy of Signature\u27s Identity, and prove our DVS scheme satisfying security based on the difficulty of the problems. Also we prove that the difficulty of the computational problem is tightly equivalent to the Strong Unforgeability of our proposed conventional signature scheme (without random oracles) related to asymmetric pairings. We believe that our underlying problems are profitable to propose many efficient cryptographic schemes

Effectiveness of a Programmed Lecture on Self-Understanding of Emotion and Autonomy in Novice Nurses

Purpose: The purpose of this research was to verify the effectiveness of a lecture, which programmed for the ability promotion of interpersonal relationship and autonomy in novice nurses, in order to prevent early resignation and to establish high-quality nursing. Methods: This intervention program consisted of a lecture and a self-check exercise, and it took for 2 hours. To evaluate their emotional changes after the educational intervention program, the participants were asked to answer self-reporting questionnaires including Emotional intelligence Quotient Scale(EQS)and Nursing Autonomy Scale(NAS). Results: Out of 3 areas of“self-effect”,“human-relations”and “situation-reactions”, a significantly higher increase was observed in “situation-reaction”. Furthermore, out of 5 factors in NAS, each score of 4 factors except“Autonomic decision-making ability”and the total score significantly increased after the intervention. There was a significant correlation between the increases in scores of “Self-effect”of EQS and those in “Practice ability”of NAS after the intervention. Consideration: The lecture and self-check exercise were effective on self-understanding and autonomy in novice nurses

ARTICLES ON AIDS IN MAJOR JAPANESE NEWSPAPERS

People in general obtain knowledge about AIDS through the mass media. It is interesting to know how newspapers have dealt with AIDS in recent years, since newspaper s are the most important mass media. The number of articles on AIDS from 1981 to 1994 was investigated in three major Japanese newspapers (Asahi, Yomiuri, and Mainichi), which are distributed nationwide. The first article appeared in 1982, and the number of articles gradually increased to a peak (total 785 articles) in 1987 when the first Japanese female patient was reported. Then, the number of articles decreased to 116 in 1989. The number of articles on AIDS in newspapers was not correlated with the reported number of patients
