background: generation of an effective dendritic cell (dc) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. objective: to compare the effects of monocyte separation methods, flask adherence (flask-dc) and magnetic activated cell sorting (macs-dc), on phenotypic and functional characteristics of resultant dcs. methods: dcs from healthy volunteers were generated ...
background: the immunomagnetic separation technique is the basis of monocyte isolation and further generation of monocyte-derived dendritic cells. objective: to compare the efficiency of monocyte positive and negative separation, concentration of beads, and their impact on generated dendritic cells. methods: monocytes were obtained using monoclonal antibody-coated magnetic beads followed the fi...
the microphase separation of hydrated perfluorinated sulfonic acid membrane nafion was investigated using dissipative particle dynamics (dpd). the nafion as a polymer was modelled by connecting coarse grained beads which corresponds to the hydrophobic backbone of polytetrafluoroethylene and perfluorinated side chains terminated by hydrophilic end particles of sulfonic acid groups [1, 2]. each f...
Background: Generation of an effective dendritic cell (DC) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. Objective: To compare the effects of monocyte separation methods, flask adherence (Flask-DC) and magnetic activated cell sorting (MACS-DC), on phenotypic and functional characteristics of resultant DCs. Methods: DCs from healthy volunteers were generated ...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
تحقیقات مختلف اثبات نموده اند که رشد و محتوای بیوشیمیایی روتیفرها می تواند تحت تاثیر نوع غذا و غلظت مواد غذایی تغییر نماید. ریز جلبک ها به عنوان یکی از منابع غذایی مهم برای کشت روتیفرها به ویژه از لحاظ شاخص های نظیر رشد، بقا، میزان پروتئین، چربی و اسیدهای چرب، ضروری می باشند. لذا تحقیق حاضر جهت مقایسه جلبک خشک (کلرلای پودری) و جلبک های تازه (ایزوکرایسیس گالبانا و نانوکلروپسیس آکولاتا) بر رشد، ت...
