poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. the aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (pmeca) particles containing 5-aminosalicylic acid (5-asa). pmeca particles were prepared using the inverse emulsification...

a recognition of appropriate soil erosion control methods along with the use of convenient alternatives in erosion control are necessary for a proper management of natural resources. run off control through polymers is one of the new methods employed in reducing soil erosion. this research was conducted to evaluate the effects of a polymer, called anionic polyacrylamide, on soil infiltarion rat...

background:  allogeneic hematopoietic stem cell transplantation (allo-hsct) is used as treatment of choice for patients with acute myeloid leukemia (aml). we aimed to evaluate the prognostic factors in 2-year overall survival of patients with non-m3 aml who underwent allogenic hsct. methods: this is a cross sectional retrospective study. demographic data and study of variables such as age, sex,...

in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or programmed cell death (apoptosis) can be induced by variety of agents including: vitamin analogs, demethylating agents, cyclic amp analogs and anti-proliferative agents. to the best of our knowledge there has been not any study specifically to ana...

the effect of kaolin on fruit and oil of olive cv. `zard’ was evaluated in a commercial orchard in fasacity, fars province. mature olive trees cv. `zard’ were sprayed with 0, 3 and 6% kaolin after 60 days, 60and 90 days and 60, 90, 120 days after full bloom. results showed that kaolin concentration and sprayingtime had not significant effects on physicochemical parameters but they had significa...

enzymatic acidolysis of canola oil through caprylic and capric acids was investigated for making structured lipids. lipozyme tl im, an sn-1,3 specific thermomyce slanuginosa lipase, was utilized as the biocatalyst in the batch reactor. reaction conditions were designed according to taguchi’s method considering fatty acid to oil ratio, at three levels (1:1, 2:1, 3:1) , enzyme load (4, 8 and, 12%...

this study investigated effects of different levels of dietary olive oil pomace on body composition, growth performance, hematological factors and sensory analysis of rainbow trout. six practical diet containing 0 (control), 2, 4, 6, 8 and 10% olive pomace were formulated and supplied to fish with an average body weight of 184.7 g being allocated randomly to rectangular concrete ponds. water fl...
