Head-up tilt testing potentiated by sublingual nitroglycerin (NTG), advocated by an Italian group, is a simple and safe but still not a standardized, diagnostic tool for the investigation of syncope. In fact, owing to its rapid spread, the original protocol received, often arbitrarily, many subsequent modifications. We now define the best methodology of the test on strictly evidence-based crite...

background: to compare a flexible, multi-dose gnrh antagonist protocol with a long gnrh .agonist protocol in poor respo materials and methods: a randomized clinical trial of 70 poor responder patients (35 patients in gnrh antagonist protocol and 35 patients in long gnrh agonist protocol) was performed at royan institute, tehran, iran. both groups were given a fixed dose of human menopausal gona...

TTCN-3 (Test and Test Control Notation version 3) is a programming language for developing tests in telecommunications domain. SIP (Session Initiation Protocol) is a key protocol standard in the modern convergent telecommunications systems. UML (Unified Modeling Language) is one of the most widely used modeling notations for describing requirements and design beyond natural language. Conformiq ...

BACKGROUND The purpose of this study was to develop a rapid and safe methacholine provocation protocol equivalent to the standard dosimeter technique. METHODS The rapid protocol comprised a short and a long subprotocol. The challenge was started with one of these subprotocols according to the subject's answers to a questionnaire and baseline lung function. If FEV1 dropped by 10% during the sh...

In 1998, the National Collegiate Athletic Association (NCAA) took steps to develop a scientific test methodology to measure and to control baseball bat performance. The resulting standard uses a hitting machine that pitches a ball at a moving bat to measure the BESR (Ball Exit Speed Ratio). Concurrently, the governing body for amateur baseball in Japan developed a test protocol for controlling ...

CaCl2 treatment followed by heat shock is the most common method for artificial transformation. Here, the cells were transformed using CaCl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. The BL21 strain of Escherichia coli (E. coli) was being susceptible using CaCl2 treatment. Some Cells were ...
