objective(s): although viral vectors are considered efficient gene transfer agents, their board application has been limited by toxicity, immunogenicity, mutagenicity and small gene carrying capacity. non-viral vectors are safe but they suffer from low transfection efficiency. in the present study, polyallylamine (paa) in two molecular weights (15 and 65 kda) was modified by alkane derivatives ...

splenic rupture during pregnancy is considered a catastrophic condition associated with high maternal and fetal mortality and morbidity. herein, we report a case of severe preeclampsia that underwent cesarean delivery with subsequent spontaneous splenic rupture. a 21-year-old primigravid woman was transferred to our center due to severe preeclampsia that underwent cesarean delivery because of u...
