Since nearly all of the hydroxyproline of the body is found in collagen, it has been suggested (1, 2) that the urinary excretion of this imino acid may be an important index of collagen metabolism. The origin of urinary hydroxyproline, however, is not definitely established. The isotopic studies of Stetten (3) in rats indirectly suggested that most of the free and peptide hydroxyproline in the ...
A simple, rapid, accurate method for determining calcium and magnesium separately in 0.1 ml. volumes of serum (or heparinized plasma) was required for the routine chemical pathology service of a children's hospital (Wilkinson, 1955-6). The apparatus used had to be generally available, the minimum of pipetting and transfer was desirable for the sake of accuracy, and the method had to be specific...
The quantity most directly related to the net charge or valence of corpuscular proteins is the electrophoretic mobility. In 1932 Abramson (1) showed that in solutions of the same ionic strength the electric mobility of the same protein at different hydrogen ion activities is directly proportional to the number of hydrogen ions bound or released as determined by titration curves. His comparisons...
In the previous chapters, various formal testing theories have been discussed. The correctness of an implementation with respect to a model is denoted by a so-called conformance relation. Conformance relations are relations between mathematical abstractions of implementations and models. Based on these conformance relations, different testing strategies have been defined. In this chapter, we co...
prompt detection of renal involvement through evaluation of microalbuminuria can both reduce mortality in diabetic patients and significantly reduce the cost of managing these patients. to this end, micral test strips have been used as a screeing tool in this group of patients though not yet in our country. the present study aimed to evaluate this test and to abtain a simpler and less expensive...
Good language learners slot in a repertoire of strategies and when language tests are at stake, test-taking strategies and test-wiseness pave pay to a prolific outcome. Among such tests, TOEFL iBT seems to be a prerequisite to academic success and a nightmare many Iranian students struggle with. Therefore, the aim of the present study was to raise awareness about the type of questions in iBT, b...
Background The first pillar of the UNAIDS 90-90-90 goal seeks to accurately identify persons living with HIV (PLHIV), a process that is predicated on facilities having the necessary HIV tests available to perform the task. In many rural settings, the identification of PLHIV is accomplished through a two-step process involving the sequential use of 2 separate rapid diagnostic tests (RDTs)....
