Objective(s): Fabrication of scaffolds with improved mechanical properties and favorable cellular compatibility is crucial for many tissue engineering applications. This study was aimed to improve mechanical and biological properties of polycaprolactone (PCL), which is a common biocompatible and biodegradable synthetic polymer in tissue engineering. Nanofibrillated chitosan (NC) was used as a n...

Background: In many countries, 1% to 3% of newborn infants are conceived by Assisted Reproductive Techniques (ART). Despite the success of ART, there is concern about the risk of congenital malformations among these infants. We report our experience to determine whether use of ART is associated with an increase in major congenital malformations or adverse pregnancy outcomes Materials and Method...

Virtual Manufacturing is a concept of executing manufacturing processes in computer environment as well as in the real word. This paper deals with the NC programming verification processes. It describes the main levels of simulation tasks. The second part of this paper focuses on the object oriented modelling and simulation architecture for simulation of NC machining operation. In this area som...

The purpose of natural cognitive systems appears to be to allow the organism to respond more rapidly to it’s environment and thus survive. This is achieved in two ways. First there are reflexes, the built-in actions an organism will take to stimulus. The second is the prediction of what the future state of the immediate environment will be and thus avoid harmful situations. The greater the inte...

We evaluated the systemic hemodynamic effects induced by nociceptin (NC) and NC-related peptides, including the NC receptor antagonist [Phe1psi(CH2-NH)Gly2]NC(1-13)NH2 ([F/G]NC(1-13)NH2) in unanesthetized normotensive Swiss Morini mice. Bolus intravenous injection of NC decreased mean blood pressure and heart rate. The hypotensive response to 10 nmol/kg NC lasted <10 minutes, whereas a more pro...

the goal of this study was to investigate the common clinical chemistry and distribution of xanthine oxidase (xo) in selected tissues of a mouse model of menopause. twenty four nmri female mice were divided into three groups: normal control (nc), and ovariectomized (ovx) groups and an estrogen-treated ovariectomized (ovx+e) group which received subcutaneous injection of estradiol benzoate (2 mg...
