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, ...

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...

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...

a 3-km reach of the luján river was studied by establishing 6 sampling stations, which were from 300 to 500 m apart. the first station was the control reading for river nutrients and particulate material. the second station measured the continuous effluent from a wastewater treatment plant flow of the city of luján and was, therefore, considered a continuous addition point of nutrients. the oth...

conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...

We detected in urine by HPLC two enzyme fractions of alkaline phosphatase (AP, EC 3.1.3.1), soluble and particulate, analogous to those in serum. The second fraction was eluted with high-salt-content eluent at the same elution time as high-molecular-mass, or particulate, AP in serum. AP characterization in urine from a patient with acute rejection crisis showed a greater sensitivity of the part...

Recent studies have suggested a link between exposure to ambient particulate matter <2.5 microm in diameter (PM(2.5)) and adverse cardiovascular outcomes. The objective of this study was to examine the effects of differing community-level exposure to PM(2.5) on daily measures of blood pressure (BP) among an adult population. During the period May 2002 through April 2003, BP was examined at 2 ti...

The effects of airborne particulate matter (PM) trace elements on health are widely concerned nowadays. Many achievements have been made while many unknowns exist. This article reports the recent research progresses, describes the effects of exposure to PM trace elements on health epidemiological evidence, toxicology findings, and raises some questions for future studies.

The aim of this study was to compare the applicability and the correlation between three commercially available instruments capable of detection, quantification, and characterization of ultrafine airborne particulate matter in the industrial setting of a tapping area in a silicon alloy production plant. The number concentration of ultrafine particles was evaluated using an Electric Low Pressure...
