Forty-six parent-referred problem 3-year-olds and 22 comparison children were assessed with parent report and observational measures; 54 were followed up at age 4, and 53 were followed again at age 6. Lower social class and greater family stress were associated with higher symptom ratings at initial referral and age 6 follow-up. Negative and directive maternal behavior and negative and noncompl...
OBJECTIVE It is aimed to characterize the true relationship of the cold ischemia time (CIT) with graft survival and with the principal post-transplantation events. MATERIAL AND METHODS We analyzed 378 kidney transplants, studying the relationship of the CIT with graft survival using a univariate analysis according to the COX model and seeking the optimum cutoff according to the Kaplan-Meier m...
The reaction-diffusion model presented by Alan Turing has recently been supported by experimental data and accepted by most biologists. However, scientists have recognized shortcomings when the model is used as the working hypothesis in biological experiments, particularly in studies in which the underlying molecular network is not fully understood. To address some such problems, this report pr...
In this study we compared the effects of duration of cold ischemia (longer and shorter ischemia) on the yield, viability and preservation of the physiological function and insulin secretion of adult human pancreatic islets in short-term (seven days) culture. Based on the tested parameters, we established that there are no major differences between these two test groups and that the storage and ...
