Denied and false pregnancies: Opposite settings of a single evolutionary conflict
Aim: A woman in denial of pregnancy is pregnant but remains unaware of her gravid state. In the case of a false pregnancy; the woman is not pregnant but believes she is and presents signs and symptoms of pregnancy. These syndromes correspond to opposite contradictions that were mainly explored separately. Our aim is to explain them by a common and consistent etiology. Method: We explore internal conflicts inherited from the evolutionary transition from solitary animals to social species. Results: The solitary and social characters are contradictory. They induce internal conflicts intrinsic to the human condition. At the reproduction level, those conflicts oppose primitive interests (genes t…
Modified position-referenced microscopy for the analysis of low-magnification biological events: a case of study in the wound healing assay with a human hepatoma cell line
Pseudo-Periodic Patterns embedded in cell-culture-plates are used for high-accurate-absolute retrieval of regions of interest in a wound healing assay of a hepatoma cell-line. The method shows more reliable results in the analysis of wound-area percentage.
To transmit genes without becoming mother: An evolutionary conflict behind denial of pregnancy
Aim: The etiology of pregnancy denial remains poorly understood. Neither necessary nor sufficient conditions can be synthesized from the risk factors identified from psychological analyses. In accordance with clinical observations, we aim to explain denial of pregnancy from an evolutionary conflict perspective. Methods: Authors investigate evolutionary biology aspects and emphasize on the transition from solitary animal species to social species. The possibility of conflicts between primitive species-perpetuation forces and subjective social-identity forces are explored. Results: As members of a social species, human beings have a dual, contradictory character of independent organisms but i…
