A convenient approach to the synthesis of medium size oligodeoxyribonucleotides by improved new phosphite method.
Improvement of the new phosphite method for the synthesis of oligodeoxyribonucleotides using the deoxyribonucleoside 3'-bis(1,1,1,3,3,3- hexafluoro-2-propyl) phosphite unit has been carried out via the hydrolysis and capping steps, without any side reaction products. The new phosphite unit and capping agent, bis(1,1,1,3,3,3-hexafluoro-2-propyl)-2-propyl phosphite, is readily activated by N-meth...
متن کاملImproved Classification of Medical Universities in Iran, a New Approach
Background: In order to check the practicality of classification of Universities of Medical Sciences (UMSs) based on their infrastructures, and scientific contributions, this study explored the most appropriate indicators to measure the size and productivity of UMSs. Methods: In the first phase, we approached a group of experts who had a deep experience in the management of UMSs and in the mini...
متن کاملNew operators through measure of non-compactness
In this article, we use two concepts, measure of non-compactness and Meir-Keeler condensing operators. The measure of non-compactness has been applied for existence of solution nonlinear integral equations, ordinary differential equations and system of differential equations in the case of finite and infinite dimensions by some authors. Also Meir-Keeler condensing operators are shown in some pa...
متن کاملA CONVENIENT SYNTHESIS OF MACROCYCLIC DIAMIDES
Some new macrocyclic dibenzotrioxadiamides, dibenzotetraoxadiamide, dibenzopentaoxadiamide, dibenzothiatrioxadiamide, tribenzotrioxadiamides and tetrabenzohexaoxadiamide (14-21), (26) and (27) have been prepared. These compounds were obtained in the macrocyclization step by reacting the diamine (4) with appropriak dicaxboxylic acid dichlorides (5-13) and (24). The cyclization does not requ...
متن کاملRedefinition of myocardial infarction: new challenges and opportunities.
Heart disease is the number one cause of death in the western world and as such constitutes an immense public health problem. The analysis of the trends in the incidence and outcome of myocardial infarction coupled to that of coronary disease mortality provides crucial insights into the determinants of heart disease, which is essential to its treatment and prevention. For example, in the face o...
