The notion of non-liberal democracy has become an inseparable element the debate on crisis liberal democracy. For some scholars and journalists, is a consequence It should be pointed out that when indicating causes this in economic, political, cultural spheres, researchers rarely address issue legitimacy identifying as its characteristics. Moreover, no one initiated broad possibility retreat fr...
Dosage compensation modulates global expression of an X chromosome and is necessary to restore the balance between X-chromosome and autosome expression in both sexes. A central question in the field is how this regulation is directed. Large non-coding RNAs, such as Xist in mammals and roX in flies, have pivotal roles in targeting chromosome-wide modification for dosage compensation. Several rec...
BACKGROUND Uncertainty about optimal red blood cell transfusion thresholds in cardiac surgery is reflected in widely varying transfusion rates between surgeons and cardiac centres. OBJECTIVE To test the hypothesis that a restrictive compared with a liberal threshold for red blood cell transfusion after cardiac surgery reduces post-operative morbidity and health-care costs. DESIGN Multicentr...
BACKGROUND Correcting the decrease in oxygen delivery from anemia using allogeneic RBC transfusions has been hypothesized to help with increased oxygen demands during weaning from mechanical ventilation. However, it is also possible that transfusions hinder the process because RBCs may not be able to adequately increase oxygen delivery. In this study, we determined whether a liberal RBC transfu...
BACKGROUND Whether a restrictive threshold for hemoglobin level in red-cell transfusions, as compared with a liberal threshold, reduces postoperative morbidity and health care costs after cardiac surgery is uncertain. METHODS We conducted a multicenter, parallel-group trial in which patients older than 16 years of age who were undergoing nonemergency cardiac surgery were recruited from 17 cen...
Standardized likelihood ratio test (SLRT) for testing the equality of means of several log-normal distributions is proposed. The properties of the SLRT and an available modified likelihood ratio test (MLRT) and a generalized variable (GV) test are evaluated by Monte Carlo simulation and compared. Evaluation studies indicate that the SLRT is accurate even for small samples, whereas the MLRT coul...
