We investigated differences in L-type Ca2+ current (ICa) between infant (INF, 1-12 mo old), young adult (YAD, 14-18 yr old), and older adult (AD) myocytes from biopsies of right atrial appendages. Basal ICa was smaller in INF myocytes (1.2 +/- 0.1 pA/pF, n = 29, 6 +/- 1 mo old, 11 patients) than in YAD (2.5 +/- 0.2 pA/pF, n = 20, 16 +/- 1 yr old, 5 patients) or AD (2.6 +/- 0.3 pA/pF, n = 19, 66...

the present research aimed to study the growth and reproductive parameters of common kilka clupeonella caspia in southern caspian sea in 2010. after measuring the length and weight of 3774 samples, they were dissected, sex determined and female gonads were weighed. sexual maturity classification was carried out based on six stages. age was determined using sagitta otoliths. length-weight relati...

This study was designed to assess the immune status of the Korean population against varicella-zoster virus (VZV) through a seroepidemiologic study. Residual blood samples were collected from diagnostic laboratories throughout Korea. Samples were collected in October 2009 to March 2010 from persons 0-79 yr of age and were tested by ELISA (Enzygnost®; Dade Behring, Schwalbach, Germany). Total se...

Health risk appraisal (HRA) is a tool for determining health risk factors and motivating individuals to maintain a healthy lifestyle. We performed this study to describe the HRA algorithm and evaluate the accuracy of an HRA program for 10-yr mortality prediction in Korean men. We used data derived from periodic health examinations of 116,927 male public officials and school personnel aged 20 or...

this study investigated whether age and gender influenced blood pressure recovery after exhaustive exercise in non-athletic males and females. 60 healthy (blood pressure was especially considered) men and women with no drug and supplement consumption participated in this study and were divided into six groups: 20-30 yr (10 males), 20-30 yr (10 females), 30-40 yr (10 males), 30-40 yr (10 females...

Abstract Orbits of inner and outer subsystems in 13 triple or higher-order stellar systems are computed updated using position measurements and, three cases, radial velocities. The goal is to determine mutual orbital inclinations, period ratios, masses complement the statistics hierarchical systems. effect on motion orbits (wobble) explicitly modeled mass ratios. Stars studied here (HD 5408, 80...

CONTEXT Measurements from all age groups defined the upper limit of the TSH reference range in National Health and Nutrition Examination Survey III. The TSH median, 97.5 centile and prevalence of subclinical hypothyroidism (SCH), normal serum T(4) and TSH greater than 4.5 mIU/liter, increased progressively with age. Age-adjusted reference ranges would include many people with TSH greater than 4...

the aim of the present study was to investigate the physicochemical performances at three sites on skin, namely the diagonal, neck and leg based on different age groups. eighteen skins pieces in 6 m, 6 m to 1 yr and 1 yr to 1.5 yr of age were selected to represent means of the respective age groups with regard to skin area. the skin area were7.4±1.41, 13.5±1.4 and 18.2±1.1 ft2 for the ostriches...

BACKGROUND & OBJECTIVES Intensive regular physical exercise training is associated with a physiological changes in left ventricular (LV) morphology and functions. This cardiac remodeling observed in the athletes is associated with the specific haemodynamic requirements of the exercise undertaken. The main objective of this study is to evaluate the effect of endurance training on cardiac morphol...

Cyclical iv therapy with pamidronate improves the clinical course in children and adolescents with osteogenesis imperfecta (OI). In this study we evaluated the effect of this therapy on bone and mineral metabolism in 165 patients with OI types I, III, and IV (age, 2 wk to 17.9 yr; 86 girls and 79 boys). All patients received iv pamidronate infusions on 3 successive days, administered at age-dep...
