Sublingual nitroglycerin (TNG) has been introduced as a promising provocative agent for tilt table testing, but it has not been compared directly with the standard isoproterenol (ISO) infusion test previously. We tried to assess the diagnostic value and safety of TNG tilt testing as compared with ISO infusion in patients with unexplained syncope. TNG and ISO tilt tests were performed in tw...

Evolution strategies (ES) have been severely criticized before they started their triumphal procession as optimization algorithms. Schwefel discussed ideas which appeared to be provocative at the first sight. SPOT provides a modern framework to test these ideas. The extreme programming methodology ...

Actual measurement of growth hormone (GH) levels in children suspected of having GH deficiency can confirm this diagnosis. However, there currently is no standard for the test. Although there is general agreement that in a short-statured child, a value of <10 microg/L in response to an appropriate provocative test indicates the possible need for GH replacement therapy, there is no agreement on ...

Not all of these have given clinically satisfactory results, either on account of the variability of their results or of the inconvenience their ...
