Maturation of oocytes is the most important stage, which determines the subsequent successful fertilization, zygote formation, attainment of blastocyst stage, normal embryo growth and development, as well as appropriate implantation. Since in some species of mammals the efficiency of IVM maturation is still very low, many studies have focused on new combinations of media supplements. In some sp...

BACKGROUND Nuclear reprogramming inculcates pluripotent capacity by which de novo tissue differentiation is enabled. Yet, introduction of ectopic reprogramming factors may desynchronize natural developmental schedules. This study aims to evaluate the effect of imposed transgene load on the cardiogenic competency of induced pluripotent stem (iPS) cells. METHODS AND RESULTS Targeted inclusion a...

Background: Oocyte in vitro maturation success rate is still low in compareision to oocyte in vivo maturation. Thus prediction and improvement of oocyte competency are two critical issues in assisted reproductive technology. New insights into oocyte-cumulus cell regulatory loop may assist our optimization of in vitro maturation technique. Maturation and developmental competency of cumulus oocyt...

Critical thinking is essential to a health professional's competence to assess, diagnose, and care for patients. Defined as the ability to apply higher-order cognitive skills (conceptualization, analysis, evaluation) and the disposition to be deliberate about thinking (being open-minded or intellectually honest) that lead to action that is logical and appropriate, critical thinking represents a...

The legal presumption used in virtually all juvenile delinquency cases in the U.S. is that all juveniles are competent to stand trial. This Article calls for the elimination of that legal presumption, which is historically based on the Dusky v. United States decision and in the adult criminal justice system. The recent decisions of the U.S. Supreme Court recognize the developmental and organic ...

background: the success of faculty members of medical sciences universities in medical education arena requires qualification and capabilities authentication in relation with education.  in order to achieve these capabilities, it is necessary to use new and influential approaches of empowerment. one of the appropriate approaches is “competency based training” (cbt). in this method, competencies...

INTRODUCTION Educational milestones are now used to assess the developmental progress of all U.S. graduate medical residents during training. Twice annually, each program's Clinical Competency Committee (CCC) makes these determinations and reports its findings to the Accreditation Council for Graduate Medical Education (ACGME). The ideal way to conduct the CCC is not known. After finding that d...
