PTEN seems to play an important role in cell cycle, growth, migration, and death. Integrins are cell surface receptors that play a role in the regulation of cell proliferation, differentiation, implantation, and embryogenesis. PTEN inhibits beta1 integrin signaling. The objective of this study is to investigate the expression of PTEN and beta1 integrin in placental tissues of early spontaneous abortion and first and third trimesters of normal pregnancy. ⋯ Our findings suggest that altered patterns of PTEN expression may be associated with abortion, but it seems that beta1 integrin does not contribute to this process as a signaling protein. Further evaluation is needed to highlight this subject.

Different pharmacokinetic models for target controlled infusion (TCI) of propofol are available in the recently launched open TCI systems. There is also a compelling choice to work with either plasma- or effect-site targets. Knowledge about the clinical consequences of different alternatives is of importance. ⋯ We observed clinically significant different results between the models. The choice of model will make a difference for the patient. To eliminate confusion - not necessarily to improve precision - we call for an optimised population based pharmacokinetic model for propofol - a consensus model!
