Visual fixation of a small, stationary target was measured in 12 young observers (mean age = 22 yr) and in 12 older observers (mean age = 70 yr). The two groups' fixation behavior did not differ on various dimensions of fixation stability: mean fixation area, intra-subject variability, or changes in fixation over successive test periods. Connections between these results and age-related changes...

Fetal exposure to synthetic glucocorticoids in sheep results in increased fetal hypothalamic-pituitary-adrenal (HPA) activity persisting to one year of age. We aimed to determine the effects of single or repeated maternal or fetal betamethasone injections on offspring HPA activity at 2 and 3 yr of age and whether changes in adrenal mediators of steroidogenesis contribute to changes in pituitary...

PURPOSE The progressivity of central precocious puberty (CPP) seems to depend on the age at presentation. We evaluated the clinical courses of CPP girls according to their age at initiation of treatment. METHODS One hundred thirty five girls with CPP diagnosed between Jan. 2003 and Dec. 2009 and regularly followed for more than one year were included. They were treated with gonadotropin-relea...

New longitudinal sleep data spanning ages 6-10 yr are presented and combined with previous data to analyze maturational trajectories of delta and theta EEG across ages 6-18 yr in non-rapid eye movement (NREM) and rapid eye movement (REM) sleep. NREM delta power (DP) increased from age 6 to age 8 yr and then declined. Its highest rate of decline occurred between ages 12 and 16.5 yr. We attribute...

This study estimated the length-weight relationship, sex ratio and population parameters of mantis shrimp, Harpiosquilla harpax from the coastal waters of Pantai Remis, Perak, Malaysia between February 2012 and October 2012. Total length and weight of 804 specimens of H. harpax were measured and the sex ratio was 1: 0.83 (M: F). Males of H. harpax were dominant over the females throughout the s...

purpose: to evaluate the role of anxiety in idiopathic acute anterior uveitis. methods: in this case-control study, three groups including 30 patients with uveitis, 30 patients with conjunctivitis, and 30 healthy controls were enrolled for estimating the anxiety level by employing zung anxiety assessment and a structured clinical interview. t test and chi square test were used for statistical a...

This article explores the use of the postrotary nystagmus (PRN) test for children younger than current norms (children 4.0 yr-8.11 yr). In the first study, 37 children ages 4-9 yr were examined in the standard testing position and in an adult-held adapted position to determine whether holding a child affected the reflex. Because the position did not affect the reflex, in the second study, PRN i...

With more patients reaching end-stage renal disease, the demand for living kidney donation is increasing rapidly. Many potential donors are now in older age groups. The effects of increasing BP with age and the measurement criteria for hypertension in this group are not well defined. A total of 238 potential donors between 18 and 72 yr of age were prospectively studied, with a comparison of "cl...

BACKGROUND Assessment of ovarian reserve is one of the steps in the management of infertile couples. Follicle Stimulating hormone (FSH) and anti-Müllerian hormone (AMH) are commonly used ovarian reserve markers in Africa. However, there is paucity of age-specific reference values for FSH and AMH among the African population. OBJECTIVE This study aimed at conducting a pilot study for generatio...
