Direct-normal solar irradiance (DNSI), the total energy in the solar spectrum incident in unit time on a unit area at the earth's surface perpendicular to the direction to the Sun, depends only on atmospheric extinction of solar energy without regard to the details of the extinction-whether absorption or scattering. Here we report a set of closure(More)
STUDY OBJECTIVE To investigate the occurrence of tramadol-associated seizures. DESIGN Retrospective cohort and case-control studies. SETTING UnitedHealth Group-affiliated independent practice model health plans, from different regions of the United States, contracting with large networks of physicians.

Platelet activating factor (Paf, 0.02 μg/kg, i.v. bolus) caused an acute increase in airways responsiveness to histamine in anaesthetized guinea-pigs prepared for recording airways resistance (R L ) and dynamic compliance (C dyn ). Aspirin pretreatment (10 mg/kg, i.v.) attenuated the return of airways responsiveness to prechallenge levels. Pretreatment with(More)

OBJECTIVES To explore coronary heart disease risk in a sample of women with multiple sclerosis (MS) by identifying the presence of established risk factors for coronary heart disease and to determine the relationship between disease severity and level of participation in health-related behaviors. DESIGN Survey study. SETTING Five general community(More)
BACKGROUND Dosing of tobramycin solution for inhalation (TSI) in cystic fibrosis (CF) patients was based on single-dose pharmacokinetic studies. This investigation was prompted by evidence of possible antibiotic accumulation in respiratory secretions with repeated dosing. The objectives were to evaluate whether tobramycin accumulates in respiratory(More)
In anaesthetized guinea-pigs pretreated with propranolol (1 mg/kg, i.v.), platelet activating factor (Paf, 0.02 μg/kg, i.v.) caused an acute increase in airways response to histamine (0.5–3.0 μg/kg, i.v.) measured as intratracheal pressure. Treatment with the cyclooxygenase inhibitors, aspirin (10 mg/kg, i.v.) or indomethacin (5 mg/kg, i.v.), enhanced the(More)
[1] Computation of components of shortwave (SW) or solar irradiance in the surface-atmospheric system forms the basis of intercomparison between 16 radiative transfer models of varying spectral resolution ranging from line-by-line models to broadband and general circulation models. In order of increasing complexity the components are: direct solar(More)
