For demonstration of DNA content in nuclei, sections were stained with Feulgen's reaction to demonstrate DNA as magenta color.
When SCA is small it can be difficult to characterize with CT, as it can appear as a solid mass (Fig. 3(b)–(d)); in this case, the great sensitivity of MR to static fluids with highly T2-weighted sequences permits demonstration of its fluid content (Fig. 3 e)), thus allowing accurate characterization.
The diagnosis of bacterial overgrowth is determined by aspiration of the jejunum and demonstration of increased bacterial contents by culture.
The methods used for the demonstrations, for content processing by students through structured brainstorming, for the development of checklists and for the replication of procedures by students with simulators or simulated patients, followed published guidelines [ 10, 11].
The diagnosis can be established by the suggestive clinical setting and demonstration of the fat density content on mammography (Fig. 3b).
Intact uptake of 125I-Ang(1 12) was significantly higher in SHR, a finding that agrees with the previous demonstration of increased Ang-(1 12) content in the myocardium of adult hypertensive rats by both immunohistochemistry and RIA.
Demonstration of reduced tumour choline content by magnetic resonance (MR) spectroscopy may also reflect apoptosis with the potential for providing an early marker of chemotherapy response in breast cancer.
For each level, serial 5 μm sections were obtained, two of which were routinely stained for histological examination using hematoxylin-eosin and Klüver-Barrera and one was submitted to Perls' Prussian Blue reaction for histochemical demonstration of the ferric iron content.
Finally, our skill-focused intervention responds to criticisms of large science courses that are teacher centered and content heavy, with exams that represent independent topics and require superficial understanding of content and little demonstration of skills (Handelsman et al., 2004; Alberts, 2005; Wood, 2009).
