Longitudinal measures of peak-compensated static acoustic admittance and tympanometric width are reported for infants and toddlers from 6 months to 30 months of age, based on over 1600 assessments of 88 children during a 24-month period. The subjects were all African-American children in full-time day care. Significant age effects were observed, with younger children displaying lower static adm...

The present study investigated the rate of systolic blood pressure recovery (SBPR) amongst three male age groups. Ninety-six apparently healthy, non-athletic adult males (48 young [23.91±4.58 years], 32 middle-aged [41.78±5.98 years] and 16 elderly [62.87±2.57 years]) participated in the study. Subjects performed a maximal-effort ergometer exercise test. Maximal oxygen uptake (VO2max) was measu...

Introduction: Acute myocardial infarction (MI) indicates irreversible myocardial injury resulting in necrosis of a significant portion of myocardium. MI is associated with high mortality. The difference between the signs of MI in each gender is unclear. The aim of this study was to describe gender-associated differences in symptom presentation after acute MI. Methods: This analytic-descri...

OBJECTIVE This study describes the parenting and psychopathology of mothers with ADHD of adolescents with ADHD (MCA), non-ADHD mothers of adolescents with ADHD (CA), and non-ADHD mothers of adolescents without ADHD (COMP). METHOD Two sets of pairwise comparisons: (a) COMP versus CA and (b) CA versus MCA were conducted. We hypothesized that CA would experience greater distress in parenting and...

OBJECTIVE This study aimed to investigate the adolescent brain activation patterns in response to performance feedback (PF), social reward (SR) and monetary reward (MR) and their association with psychological factors. METHODS Functional magnetic resonance imaging (fMRI) was performed while middle school boys (n=15) performed tests pertained to PF, SR and MR. The brain activation pattern in e...

BACKGROUND AND AIM The prevalence of ulcerative colitis (UC) is increasing steadily in Japan. In Western countries, a bimodal distribution, with UC onset peaks in youth and middle age, is observed, and smoking cessation is reported as a risk factor for UC. However, there are few reports on a bimodal distribution of onset age among Japanese patients. Therefore, the distribution of onset age and ...

Functional magnetic resonance imaging (fMRI) was used to explore the neural correlates of semantic judgments in the auditory modality in a group of 9- to 15-year-old children. Subjects were required to indicate if word pairs were related in meaning. Consistent with previous findings in adults, children showed activation in bilateral superior temporal gyri (BA 22) for recognizing spoken words as...

Previous research has shown that traits from the domain of conscientiousness tend to increase with age. However, previous research has not tested whether all aspects of conscientiousness change with age. The present research tests age differences in multiple facets of conscientiousness (industriousness, orderliness, impulse control, reliability, and conventionality) using multiple methods and m...

Research demonstrating that socioeconomic status (SES) differentials in health are smaller at older ages often considers only individual SES measures (e.g., income, education) but not community SES measures (e.g., community poverty rate), although the gerontological literature suggests that community context may be particularly salient in the lives of older adults. This study uses two national ...

Acne is the most common disease treated by dermatologists based upon data from the 1996 U.S. Census. The lifetime prevalence of acne approaches 90%. Acne vulgaris is a chronic disease with the highest prevalence in adolescents. The onset of acne vulgaris occurs during the onset of puberty, which is at a younger chronological age in females than in males. Both females and males have acne that ex...
