Published studies world wide demonstrate that measures of human development and health status vary depending on the month of birth but these patterns are not always consistent and sometimes even conflict. Direct factors related to the birth season that may significantly differentiate morphological and functional traits and mechanisms causing these relations have not been found so far. On the ba...

BACKGROUND Developmental defects of enamel (DDE) may be influenced by health problems and illness in children. The aim of the study was to identify the main characteristics of birth (delivery) and adverse medical conditions during the first month of life that may be related to DDE in permanent teeth. METHODS 1000 schoolchildren between the ages of 9 and 11 years were selected for this cross-s...

Social influence has been shown to profoundly affect human behavior in general and technology adoption (TA) in particular. Over time, multiple definitions and measures of social influence have been introduced to the field of TA research, contributing to an increasingly fragmented landscape of constructs that challenges the conceptual integrity of the field. In this vein, this paper sets out to ...

BACKGROUND Doppler echocardiographic measurements of both valves during intrauterine life can be used to calculate peak early filling velocity (E)/late peak atrial filling velocity (A) ratio as a single index of diastolic performance. The purposes of this study were to estimate the changes in atrioventricular valve flow from gestational age 37-40 weeks to 1 month of postnatal life and to clarif...
