A copper-catalyzed regio- and intermolecular aminofluorination of styrenes has been developed. In this reaction Ph-I=N-Ts and Et3N·3HF act as nitrogen and fluorine sources, respectively. The obtained β-fluoro-N-Ts-phenethylamines can be N-alkylated with subsequent deprotection affording the corresponding β-fluoro-N-alkylated phenethylamines, which are interesting building blocks for compounds a...
Background: Tubal sterilizatio (TS) is a widely applied contraceptive method worldwide. Although most studies have described sterilization as a safe method, there are reports of TS complications. The aim of this study was to evaluate the effects of TS on ovarian function. Materials and Methods: The study comprised of 2 protocols A and B. A Protocol: survey ovarian hormone and B protocol: study ...
Introduction: Tubal Sterilization (TS) is one of the most common contraceptive methods. Some researchers believe that TL has complications, whereas there are contradictory reports about TS effects on ovarian function. The aim of this study was to evaluate the indices of oxidative stress and survey ovarian function after TS. Methods: The study groups consisted of 63 Sprague Dawley female rats. T...
in this paper, we introduce a takagi-sugeno (ts) fuzzy model which is derived from a typical multi-layer perceptron neural network (mlp nn). at first, it is shown that the considered mlp nn can be interpreted as a variety of ts fuzzy model. it is discussed that the utilized membership function (mf) in such ts fuzzy model, despite its flexible structure, has some major restrictions. after modify...
