OBJECTIVE To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] level and history of community-acquired pneumonia (CAP). PATIENTS AND METHODS We identified 16,975 individuals (≥17 years) from the third National Health and Nutrition Examination Survey (NHANES III) with documented 25(OH)D levels. To investigate the association of 25(OH)D with history of CAP in these partici...

This paper studies the phenomenon of service-led growth in India over the past two decades from the perspective of household expenditure. We use consumption expenditure data from four recent “thick” rounds of the National Sample Survey in 1993-94, 2004-05, 2009-10 and 2011-12, and study aggregate services as well as 5 individual categories – education, healthcare, transportation, entertainment,...

1 A growing body of evidence implicates the oocyte as a key regulator of ovarian 2 folliculogenesis and early embryonic development. We have screened bovine cDNA microarrays 3 (containing ESTs representing > 15,000 unique genes) with Cy3 and Cy5 labeled cDNA derived 4 from bovine oocyte samples collected at two different stages of meiotic maturation (germinal 5 vesicle versus metaphase II; n = ...

BACKGROUND Reference charts are widely used in healthcare as a screening tool. This study aimed to produce reference growth charts for school children from West Malaysia in comparison with the United States Centers for Disease Control and Prevention (CDC) chart. METHODS A total of 14,360 school children ranging from 7 to 17 years old from six states in West Malaysia were collected. A two-stag...

PURPOSE To evaluate the relationship between the structural damage as assessed by time-domain optical coherence tomography (OCT) and functional changes in glaucoma. METHODS In total, 190 patients with normal tension glaucoma or primary open angle glaucoma were included in this study. The thickness of retinal nerve fiber layer (RNFL) around the optic disc and the area of RNFL defect were deter...

Runoff potentiality of a watershed was assessed based on identifying curve number (CN), soil conservation service (SCS), and functional data analysis (FDA) techniques. Daily discrete rainfall data were collected from weather stations in the study area and analyzed through lowess method for smoothing curve. As runoff data represents a periodic pattern in each watershed, Fourier series was introd...

An improved and updated version of the statistical LOWESS fit to the marine Sr/Sr record and a revised look-up table (V3:10/99; available from [email protected]) based upon it enables straightforward conversion of Sr/Sr to numerical age, and vice versa, for use in strontium isotope stratigraphy (SIS). The table includes 95% confidence intervals on predictions of numerical age from Sr/Sr. Thi...
