Calorimetric analysis depends on the direct proportionality between the heat changes that occur during chemical reactions and the amount of reacting substances. Potential uses of calorimetry in the clinical laboratory are discussed, with examples. The calorimetric technique does not require optically clear specimens, and if the specificity of the measured reaction is assured, calorimetry can be...

The emerging field of corporate demography views corporations and industries in a similar way to human or animal individuals and groups. In spite of a surprisingly large overlap of subject matter with economics, corporate demography is not well-known by, nor easily accessible to economists. An extremely useful recent book, The Demography of Corporations and Industries, by Glenn R. Carroll and M...

The literature has described the clinical aspects of the laminate veneer restoration; however, the laboratory preparation of these veneers has not been detailed This paper outlines a step-by-step laboratory technique for the construction of a commercially available laminate veneer, Mastique.® J_Jaminate veneers have been successfully used on patients with hypoplasia, tetracycline staining, fluo...

ABSTRACT With the COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), many areas in world witnessed an increase fungal infections and corresponding mortality. In our study, we attempted to identify common pathogens encountered patients with find microbiological histopathological parameters that may help diagnose these etiological agents. The clinical manife...

Laboratory testing is a highly complex process and, although laboratory services are relatively safe, they are not as safe as they could or should be. Clinical laboratories have long focused their attention on quality control methods and quality assessment programs dealing with analytical aspects of testing. However, a growing body of evidence accumulated in recent decades demonstrates that qua...

1. Two cases of "Landry's syndrome" are reported, the term being used to indicate an ascending paralysis of the spinal cord. 2. One case is due to compression by a chloroma, and the mechanism of ascent of the paralysis is discussed. The second case is due to a presumed infective agent. 3. The varied causes of the syndrome are emphasised, as well as the necessity to exclude compression as a caus...

Background Contrast enhanced MRA is a well validated and widely used technique for noninvasive vascular imaging. Significant advances in coil development, parallel imaging, and view-sharing techniques can enable imaging with very high spatial and/or temporal resolution which can be tailored to very specific or problematic clinical situations. Cartesian acquisition with projection like reconstru...
