We calculated the diagnostic accuracy of these index tests in reference to a primary microbiologic gold standard (positive mycobacterial culture of sputum or bronchoalveolar lavage fluid), and measured their likely clinical impact on additional tuberculosis cases detected among those not prescribed initial TB treatment.
This region is an important prospective area for gold with extensive research having been carried out on the secondary alluvial gold and primary gold mineralization [44 48], soil quality [49, 50] and water quality [51].
The density of primary gold particles within the self-assembled aggregates can be tuned by varying the molar mass of the grafted polymer.
In addition to the hypogene and supergene hematite sources, other possible sources of Fe in the studied sediments are the sulphide minerals pyrite and arsenopyrite associated with the primary gold bearing quartz veins [48].
She's still got it (see: Benghazi hearings), and it's Democratic primary gold (see: post-Benghazi-hearing polls).
Much later, to identify viral proteins inducing specific structural configurations at the cellular level, immunostaining with a primary antibody followed by colloidal gold secondary antibody was employed to mark the location of specific viral proteins.
This study systematically assesses the effect of a secondary ENM (i.e., pluronic acid modified single-walled carbon nanotubes, PA-SWNTs) on a primary particle (i.e., gold nanospheres, AuNSs) transport through saturated porous media under a wide range of aquatic conditions (1 100 mM NaCl).
Hearing level as an objective outcome, although clinically important, is problematic for a primary care study because the gold standard of pure tone audiometry is very difficult to do reliably in primary care practices, particularly in younger children and where usual high levels of background noise invalidate the findings.
Finally, a complete chart audit, which we performed, is the gold standard in a primary care setting, for identifying the most patients with a given condition.
