The purpose of preimplantation genetic diagnosis by embryonary biopsy is to identify genetic alterations prior to the implantation of embryos produced by in vitro fertilization. The most important aim is the selection of genetically healthy embryos due to... see more

As the number of frozen human embryos continues to rise daily, with numbers not expected to fall, an answer must be found to this dilemma. Four possible solutions have been suggested: a) thaw the embryos and allow them to perish; b) thaw them and donate t... see more

The search for IVF efficacy leads to a higher embryo production than it is necessary for implantation; this results in an excess of embryos which are kept frozen. This amount of frozen embryos inevitably increases. The donation/adoption are among the poss... see more

Scientific research has made possible new hopes for the cure of diverse pathologies provoked by degenerative processes or by direct damage on organs and tissues. One of the fields of study most promising is the use of pluripotential cells, being their mai... see more

The effect of antifreeze protein type III (AFPIII) and human heat shock protein 70 (HHSP70), added to the vitrification medium of mouse embryos, on post-freeze/thaw in vitro embryonic growth rates and cell numbers were investigated. In total 20 female mic... see more

The aim of our study was to test the cryoprotective proprieties of 7 vitrification media, designed in our laboratory, using the 0.25 mL straws vitrification method, with one equilibration step. As biological material we used mouse females, age 2 months su... see more

This article, which envelops a case study and development of umwelt theory, addresses four research questions: At what point does the human umwelt emerge? What umwelt transitions can be identified in the ontogenesis of the early human umwelt? What is char... see more

Abstract: The aim of this study is to establish the position of the inferior alveolar nerve in relation to the Meckel’s cartilage, the anlage of the mandibular body and primordia of the teeth, and also to trace the change in nerve trunk structure in the h... see more

The utilization of human embryos in the biological research has generated a bioethical debate from the ontological point of view about whether or not to consider the embryo as a human person. This paper review the ontological statute of the human embryo f... see more
