Background. We studied 715 patients 2 weeks after myocardial infarction to test the hypothesis that short-term power spectral measures of RR variability (calculated from 2 to 15 minutes of normal RR interval data) will predict all-cause mortality or arrhythmic death. Methods and Resuls.We performed power spectral analyses on the entire 24-hour RR interval time series. To compare with the 24-hou...

AIMS To assess whether lung function in late childhood had improved in subjects born extremely prematurely in the early 1990s compared to the early 1980s, and whether neonatal factors in the respective periods had different impact on long-term pulmonary outcome. DESIGN Population-based, controlled cohort study. Lung function was determined in 81 of 86 (94%) eligible subjects born with gestati...

Abstract Background Single mothers in South Korea are vulnerable to developing smoking habits, due many difficulties and limitations; however, they have often been overlooked by cessation support services. Therefore, this study aimed investigate the general smoking-related characteristics of single registered with Visiting a Smoking Cessation Service Seoul, Korea, identify factors associated ma...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

OBJECTIVE To assess the contribution of postnatal factors to failure to thrive in infancy. METHODS 11 900 infants from the Avon Longitudinal Study of Parents and Children (ALSPAC), born at 37-41 weeks' gestation, without major malformations and with a complete set of weight measurements in infancy (83% of the original ALSPAC birth cohort) were studied. Conditional weight gain was calculated f...

Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed by prenatal stress. Whether enriched environment treatment (EE) in early postnatal periods can cause a recovery from these deficits is unknown...

Stress in animals causes not only immediate reactions, but may affect their biology for long periods, even across generations. Particular interest has been paid to perinatal stress, but also adolescence has been shown to be a sensitive period in mammals. So far, no systematic study has been performed of the relative importance of stress encountered during different life phases. In this study, g...
