The ever-growing numbers of medical digital images and the need to share them among specialists and hospitals for better and more accurate diagnosis require that patients' privacy be protected. As a result of this, there is a need for medical image watermarking (MIW). However, MIW needs to be performed with special care for two reasons. Firstly, the(More)
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(More)
This paper presents an automatic region of interest (ROI) segmentation method for application of watermarking in medical images. The advantage of using this scheme is that the proposed method is robust against different attacks such as median, Wiener, Gaussian, and sharpening filters. In other words, this technique can produce the same result for the ROI(More)
OBJECTIVE The aim of this study was to elucidate the mechanism(s) responsible for the vasorelaxant effect of Nigella sativa (N. sativa). METHODS The activity of different concentrations of N. sativa extract was evaluated on contractile responses of isolated aorta to KCl and phenylephrine (PE). RESULTS The extract (2-14 mg/mL) induced a concentration(More)
OBJECTIVE Diabetes is an important risk factor for cardiovascular events. The great percent of morbidity in patients with diabetes is due to endothelial dysfunction. The present study investigated the effects of hydroalcholic extract of Nigella sativa (N. sativa) on contractile and dilatation response of isolated aorta in streptozotocin (STZ)-induced(More)
As a new interest for biodegradable non-hazardous biolubricant from renewable resources, microalgae lipid is suggested as a new feedstock by introducing the microalgae-based lubricants. Chlorella vulgaris was successfully grown in a cheap substrate-based mixotrophic medium. The kinetic modeling of microalgae growth, lipid production, and substrate(More)
In this work time dependent heat transfer flow through a kerosene based ferrofluid is considered. The flow is in a cylindrical geometry with the height and diameter of 10 mm. Computational fluid dynamics was used to simulate the system. In CFD simulations mixture model was applied to describe the behavior of the magnetic particles. A uniform magnetic field(More)
