Fact: All particulate corticosteroid preparations have been implicated in rare cases of paraplegia, whereas no definitive evidence exists of paraplegia resulting from injection of non-particulate steroids. Studies directly comparing the effectiveness of particulate and non-particulate steroids largely show no differences between the two, with respect to relief of pain, restoration of function, ...

We study the clustering of the mass distribution in cold dark matter models using large cosmological N-body simulations. We investigate spatially-at models with a cosmological constant and scale-invariant (n = 1) primordial power spectra, as well as open-bubble innation models. All the models we consider are normalized according to the uctuation amplitude measured in the COBE-DMR microwave back...

We use panel data from Germany to analyze the effect of population density on urban air pollution (nitrogen oxides, particulate matter, ozone, and an aggregate index for bad quality [AQI]). To address unobserved heterogeneity omitted variables, we present long difference/fixed effects estimates instrumental variables estimates, using historical soil as instruments. Using our preferred find that...

since particulate matter (total suspended particles and particulate matter with median aerodynamic diameter less than 10 µm) is one of the important pollutants in the ambient air of tehran, the capital of iran, organic substances, inorganic substances and lead levels in tsp and pm10, correlation between tsp and pm10 concentrations, ratio among the two fractions and relation between tsp and pm10...

background: welding is one of the most exercised industrial processes which welders are exposed to chemical and physical hazardous agents. this study was conducted to evaluate occupational and environmental exposures to aerosols generated by welding processes in a factory. methods: a total of 28 samples of aerosols were collected at 4 different locations including indoor, outdoor, source of wel...

OBJECTIVES The Occupational Health and Safety Administration (OSHA) outlines specific requirements governing the use of respiratory protection for workers dealing with dust or other aerosolized compounds. Health care workers may be exposed to bone dust produced during otologic procedures, creating an occupational hazard. The purpose of this research was to quantify the total suspended particula...

We characterize a representative haze event from a series of periodic particulate matter (PM) episodes that occurred in Shanghai during winter 2014. Particle size distribution, hygroscopicity, effective density and effective density single particle mass spectrometry were measured determined online, along with offline analysis of water-soluble inorganic ions and single particle mass spectrometry...

Rat very low density lipoproteins (d smaller than 1.006), biologically labeled in esterified and free cholesterol, were obtained form serum 6 h after intravenous injection of particulate (3-H) cholesterol. When injected into recipient animals, the esterified cholesterol was cleared form plasma with a half-life of 5 min. After 15 min, 71% of the injected esterified (3-H) cholesterol had been tak...
