as igm and iga-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of igm and iga enriched immunoglobulins. fraction iii which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using sephadex deae a-50 and 0.1 m tris-d.35m naci buff...

in this study the optimal amount of enriching artemia franciscana with a synbiotic combination of pediococcus acidilactici and fructooligosaccharide (fos( was investigated. the experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics p. acidilactici (1×109, 1×108 and 1× 107 cfu per l) and multi-level enriched prebiotic fos (1, 2 and 5) g per l of solu...

background: platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. platelet concentrates can be prepared by the apheresis method or from the whole blood using the buffy-coat or platelet-rich plasma methods. the purpose of this study was to compare four variations of platelet-rich plasma method based on double...
