Abnormal masses (tumors, thrombi, vegetations) must be distinguished from normal cardiac structures that may mimic a mass. The echocardiographic evaluation of intracardiac masses is dependent on the ability to distinguish normal from abnormal findings.1 Erroneous diagnoses may lead to inappropriate medical therapy and even inappropriate surgery.3 Recognition of such normal variants depends on i...

relations group, and were then, over the course of a week, given four sets of tasks: (1) pretest classical analogies; (2) matching relations; (3) post-test classical analogies; and (4) crossdomain analogies. Results: ANOVA showed an improvement in performance from preto postclassical analogies and transfer of analogical reasoning skills to the novel cross-domain analogies. However, planned comp...

The development of the diagnostic and classification criteria for headache disorders from the International Headache Society has benefited not only practicing headache specialists but also epidemiologists. We now have a wealth of data from international epidemiological studies on the prevalence and cost of migraine and other headache disorders. The data reveal the significant impact these disor...

Codes Description of C Nonsingular C injective – i.e. ∀x, x′ ∈ X , x 6= x′ =⇒ C(x) = C(x′) Uniquely Decodable The extension the code is nonsingular. Prefix/Instantaneous/Self-punctuating No code word prefixes another: for all distinct x′, x′′ ∈ X , C(x′) does not start with C(x′′) We illustrate this below with the following example for the symbols {a, b, c, d} taken from Chapter 5 in Cover and ...

Over the last two decades, it has become evident that decreased bioavailability of endothelial nitric oxide (NO) produced from endothelial NO synthase (eNOS), referred to as endothelial dysfunction, plays a crucial role in the development and progression of atherosclerosis. Much progress has been made in understanding the mechanisms of decreased endothelial NO bioavailability at the levels of r...

A fluorescent dye, FEB, with high fluorescence quantum yield for tumour imaging is reported. FEB dyes can be efficiently synthesized in three steps and then easily modified with either PEG or PEG-iRGD to yield FEB-2000 or FEB-2000-iRGD, respectively. Both modified dyes showed negligible toxicity and were thus able to be adopted for in vivo tumour imaging. PEG modification endowed the dye FEB-20...

terminal heat stress in mediterranean climates like ahwaz is reduced wheat yield. in order to study effect of terminal heat stress on yield and yield components of 20 spring bread wheat cultivars, an experiment was conducted in ramin university of agricultural and natural resources, ahwaz in 2007-2008. the experimental design was stripe block design in randomized complete block design with thre...
