objective(s):growing evidence indicates that extract of ginkgo biloba (egb) attenuates hippocampal-dependent memory deficit in aged individuals; however, very little is known about the effect of egb on the structure of hippocampus. therefore we examined the egb-induced morphological changes of the cornu ammonis (ca) region in aged rats. materials and methods: sixteen aged male wistar rats, 24 m...

In this study, the effect of overlapping percentage on microstructure and mechanical properties of a single-pass coating by Inconel 625 powder laser has been investigated for quench-tempered ASTM A592 steel. In order to have a structural analysis, the inter dendritic distance was evaluated. For this purpose, scanning electron microscopy (FESEM) and Digimizer software were adopted. In order to i...

In this research, dissimilar welding between 4130 low alloy steel and austenitic stainless steel 316L has been investigated using Gas Tungsten Arc Welding (GTAW). Two types of filler metals, including ERNiCr-3 and ER309L, were used for this purpose. Moreover, the joint microstructures including the weld metals, heat affected zones and interfaces were characterized by optical and Scanning Electr...

Abstract Recently, dendritic mesoporous silica nanoparticles with widespread applications have attracted great interest. Despite many publications (>800), the terminology “dendritic” is ambiguous. Understanding what possible “dendritic structures” are, their formation mechanisms and underlying structure–property relationship fundamentally important. With advance of characterization technique...

objective it has previously been shown that prenatal maternal administration of boswellia serrata gum resin (frankincense) improved learning and memory performance associated with an increase in the size of neuronal bodies in ca3 (cornu ammonis) of hippocampus. continuing the previous work, a morphometric study was designed on ca3 field to examine precisely the effect of prenatal administration...
