From Particle Size Analysis ( Psa 1970 ) to Particulate Systems Analysis ( Psa 2003 ) †
I t is now fully accepted that industrial processes involving particulate systems are in the mainstream of chemical engineering practice, research and education. A scientific approach to particle processing implies the study and development of means for characterizing particles, the primary characteristic being particle size and distribution. This paper, by members of the EFCE working party on ...

was to assess analytical issues surrounding the measurement of PSA in prostate cancer screening. A subsequent review article published earlier this year in the Annals of Clinical Biochemistry titled " Pre-and post-analytical factors that may influence use of serum prostate specific antigen and its isoforms in a screening programme for prostate cancer " 1 discusses the findings and draws from th...

متن کاملPopulation-based analysis of normal Total PSA and percentage of free/Total PSA values: results from screening cohort.
OBJECTIVES To examine the distribution of total prostate-specific antigen (tPSA) and percentage of free/total PSA (%f/tPSA) values in patients undergoing prostate cancer screening in Canada. METHODS The data from 4 consecutive annual prostate cancer screening events held in Montreal, Canada were examined with respect to age, tPSA, and %f/tPSA in 3222 men. RESULTS Within the entire cohort, t...

Bordetellosis, caused by Bordetella avium infection, is characterized by tracheal inflammation, epithelial cell degeneration, and tracheal distortion. The inflammation results from dermonecrotic toxins produced by B. avium. Inflammatory reactions are accompanied by generation of reactive oxygen metabolites (ROM) that kill cells. Antioxidant enzyme activity associated with either sodium selenite...
