Background: One of the most important components of coronary artery bypass graft surgery is need for blood transfusion that increases morbidity and mortality. The aim of this study was to evaluate the factors affecting the need for blood transfusion during off pump coronary artery bypass (OPCAB) surgery.Methods: In this descriptive case control study 923 patients who had undergone OPCAB ...
a survey of tissue oxygenation differences in intensive care patients with blood transfusion haghighimoghadamy [1] *, valizadeh ma [2] , feizi a [3] received: 26 dec, 2011 accepted: 7 mar, 2012 abstract background & aims : greater than 75% patient that hospitalized in intensive care units has anemia. blood transfusion in icu is not recently and about 40-70% patients in intensive c...
A successful pregnancy requires synchronized adaptation of maternal immune-endocrine mechanisms to the fetus. Here we show that galectin-1 (Gal-1), an immunoregulatory glycan-binding protein, has a pivotal role in conferring fetomaternal tolerance. Consistently with a marked decrease in Gal-1 expression during failing pregnancies, Gal-1–deficient (Lgals1–/–) mice showed higher rates of fetal lo...
Isolation of fetal cells from maternal blood is under active investigation as a noninvasive method of prenatal diagnosis. In the context of studying cell surface antigens expressed on fetal cells we discovered that fetal cells from a prior pregnancy also could be detected. This led to the appreciation of the persistence of fetal cells in maternal blood for as long as 27 years postpartum, and th...
Humans and rodents exhibit a peculiar type of placentation in which zygotederived trophoblast cells, rather than endothelial cells, line the terminal maternal vascular space. This peculiar aspect of the placental vasculature raises important questions about the relative contribution of fetal and maternal factors in the local control of hemostasis in the placenta and how these might determine th...
TIM-3 is constitutively expressed on subsets of macrophages and dendritic cells. Its expression on other cells of the innate immune system and its role in fetomaternal tolerance has not yet been explored. In this study, we investigate the role of TIM-3-expressing innate immune cells in the regulation of tolerance at the fetomaternal interface (FMI) using an allogeneic mouse model of pregnancy. ...
Placentation is associated with several steps of vascular adaptations throughout pregnancy. These vascular changes occur both on the maternal and fetal sides, consisting of maternal uterine spiral arteries remodeling and placental vasculogenesis and angiogenesis, respectively. Placental angiogenesis is a pivotal process for efficient fetomaternal exchanges and placental development. This proces...
