Association of early cleavage, morula compaction and blastocysts ploidy of IVF embryos cultured in a time-lapse system and biopsied for genetic test for aneuploidy.

IVF embryos have historically been evaluated by morphological characteristics. The time-lapse system (TLS) has become a promising tool, providing an uninterrupted evaluation of morphological and dynamic parameters of embryo development. Furthermore, TLS sheds light on unknown phenomena such as direct cleavage and incomplete morula compaction.

[Cardiac herniation and torsion after transpericardial pneumonectomy].

This article presents the case of a 43 year old woman with right-sided lung cancer. She underwent transpericardial pneumonectomy. After an uneventfull surgery, the patient was transferred to the intensive care unit for postoperative monitoring.

[Effect of short-term aerogenic hypoxia on the behavior of heart rate and blood pressure in newborn swine].

The adaption of the cardiovascular system to hypoxia has been examined in piglets aged 3 to 81 hour. The reaction of the piglets to a shorttime normobaric hypoxia was very different: In 50% there was an inadequate reaction with decrease of blood pressure, heart rate, pulse pressure and therefore of stroke volume, in 30% there was in compliance with the adult mechanism a compensatory increase of blood pressure, heart rate, pulse pressure and stroke volume. Only in 2 cases a compensatory increase of blood pressure could be observed in combination with a simultaneous decrease of heart rate.
