Low starch/corn silk/ZnO as environmentally friendly nanocomposites assembling on PET fabrics.

Starch is a benign bio-polymeric material with a diversity of desirable functionalities namely biocompatibility and hydrophilicity features. Besides, corn silk with cellulose-protein structure can be used as an available and clean compound for medical applications. Hence, the advantages of both mentioned biocompatible compounds with potentiality to form hydrogel are considered via their combination.

Synthesis of applicable hydrogel corn silk/ZnO nanocomposites on polyester fabric with antimicrobial properties and low cytotoxicity.

Corn silk as a clean and cheap agricultural waste with protein and cellulosic structure and traditionally usages was applied on polyester for the first time to increase the cell viability of zinc oxide on polyester fabric creating good hydrogel properties. The corn silk was first dried under sunlight, powdered and dispersed into the homogeneous solution using sodium hydroxide/urea at boil. Zinc acetate and a cationic surfactant along with the polyester fabric were placed in the alkali solution with or without corn silk at boil for 1 h.

The Effects of Nigella Sativa Hydro-alcoholic Extract on Memory and Brain Tissues Oxidative Damage after Repeated Seizures in Rats.

Regarding the therapeutic properties of Nigella sativa (NS), the effects of the plant hydro - alcoholic extract on learning, memory and brain tissues oxidative damage were investigated in penthylenetetrazole (PTZ) - induced repeated seizures. There were 4 experimental groups including: 1- control group; received saline, 2- PTZ group ; received saline and PTZ (50 mg/Kg, i.p) , 3-PTZ- NS 200 and 4- PTZ- NS 400 ; received 200 and 400 mg/Kg of NS extract respectively, before PTZ injection in 5 consecutive days.
