Glycogen synthase kinase (GSK)-3β mediates amyloid-beta (Aβ) and oxidative stress-induced neurotoxicity in neurodegenerative disorders. Natural products with antioxidant activity, such as Sargassum (S.) oligocystum may modulate GSK-3β enzyme and protect against Aβ-induced neurotoxicity. Therefore, we aimed to assess the neuroprotective effects of a methanolic extract of S. oligocystum against A...

background: severe preeclampsia is a quite well-known entity with high incidence of both maternal and fetal morbidity and mortality. although little is known about its etiology, inherited disorders of hemostasis and antiphospholipid syndrome have been postulated as common causes. the present study was conducted to evaluate the association of these two entities with preeclampsia in a group of ir...

The aim of this study was to compare the serum C, S proteins and factor V Leiden between sickle cell patients and the control group. Materials and Methods: In this case-control study, perf...
