abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
objective(s): erythropoietin (epo), is a 34kda glycoprotein hormone, which belongs to type 1 cytokine superfamily. epo involves in erythrocyte maturation through inhibition of apoptosis in erythroid cells. besides its main function, protective effects of epo in heart and brain tissues have been reported. epo has a critical role in development, growth, and homeostasis of brain. furthermore epo h...
مقدمه: آسم بیماری التهابی مجاری تنفسی است که عوامل ژنتیکی و محیطی مختلفی در آن نقش دارند.بیماری آسم را از جنبه های ایمونولوژیک می توان مورد بررسی قرار داد. ژن های مختلفی از سیستم ایمنی در ایجاد و تشدید آسم دخیل هستند. از جمله این ژن ها در سیستم ایمنی خانواده tlrs می باشد.از انجا که ایجاد چندشکلی ژنی در ژنها باعث تغییر در نحوه پاسخ سیستم ایمنی می گردد در این مطالعه به بررسی چند شکلی ژنی در خانوا...
introduction: in recent years, influenza viruses have caused moderate to severe infections all around the world while so far there is no influenza vaccine that can protect people with only one dose of injection. in this regard, producing a universal vaccine based on virus-like-particles (vlp) could be an ideal approach. methods: in this study, the full-length orf of influenza hemagglutinin (ha...
background and aims: the contribution genetic and antigenic diversity of h9n2 influenza viruses in evading from immune responses, cytotoxic t lymphocytes (ctl) epitopes in hemagglutinin (ha) protein restricted by hla binding peptides was identified. materials and methods: phylogenetic analyses were carried out for all of full length ha and deduced amino acid sequences of h9n2 viruses available ...
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
honeybees like the other animal creatures require proteins, fats, carbohydrates, minerals vitamins and water for their maintenance, growth and reproduction. normally they obtain their nutritional requirements from flowers but there are times when there aren’t sufficient flowers within reach they become in need of supplemental feeding. some such nutritional substances as soybeans, glutens, yeast...
