ABSTRACT Reports on the use of elastography in gynecology and obstetrics remain scare, and most have used static sonoelastography. In gynecology, most studies are related to the field of oncology. In obstetrics, the primary research object has been to estimate cervical stiffness during pregnancy. The accuracy and reliability of the quantitative evaluation of cervical stiffness using elastography has not yet been established due to the lack of comparative reference materials. More studies are needed to determine the utility of the technique in these fields. How to cite this article Ryo E. Real-Time Tissue Elastography in Gynecology and Obstetrics.

Lysine Synthesis

Exposure of ultraviolet-irradiated, adenine-dependent haploid yeast to 2,6-diamino purine (an analogue of adenine) consistently gives rise to approximately 0.5% recessive biochemical mutants. This frequency is 22-fold higher than that obtained with either agent alone, and 150-fold higher than the spontaneous frequency. The distribution of mutants into nine discrete nutritional groups attests to the utility of the method for procuring relatively large numbers of different biochemical mutants. Several new gene markers for amino acid requirements are described, including one which controls an apparent single block for both lysine synthesis and respiratory competence.
