conclusion our results indicate that dsct coronary angiography provides high diagnostic accuracy for the evaluation of cad patients during daily routine practice of a referral cardiovascular setting. background there are numerous studies that address the diagnostic value of dual-source computed tomography (dsct) as an alternative to conventional coronary angiography (cca). however, the benefit ...

conclusions: considering the low rate of ceftriaxone resistance amongst isolated pneumcocci.in this study, only ceftriaxone treatment of adult patients with invasive pneumococcal infections (other than cns infections) is sufficient; but pediatric patients and patients with cns infections should be treated with ceftriaxone and vancomycin. apparently, diminution of vancomycin use can be resulted ...

background: toxoplasmosis is a zoonotic disease with widespread distribution throughout the world. it is caused by the pro­tozoan parasite toxoplasma gondii . as laboratory diagnosis of toxoplasmosis is not straightforward, this study was aimed to compare the sensitivity and specificity of conventional and unconventional methods of diagnosis based on the meas­urement of igm and igg for determin...

conclusions pivka-ii was as efficient as afp when used as a single marker for hcc screening and the combination of two biomarkers gave a better performance. results the sensitivity and specificity of pivka-ii were 74.6% and 67.8% at a cutoff of 40 mau/ml and 64.2% and 89.7% at a cutoff of 200 mau/ml. the sensitivity and specificity of afp were 76.7% and 65.0% at a cutoff of 20 ng/ml and 60.4% a...

Knowledge is often highly specific to the conditions of acquisition, so there is limited transfer of learning from training to testing. A series of studies is reported examining specificity and transfer of learning in three very different tasks, including digit data entry, speeded aiming, and time production. These studies address a variety of theoretical issues, including those involving menta...
