long-term exposure to opiates induces physical dependence and tolerance. the main goal of this study was to evaluate the effects of dextromethorphan and midazolam and their combination on morphine tolerance and dependence in mice. different groups of mice were rendered randomly and received morphine (50 mg/kg, sc), morphine (50 mg/kg, sc) + dextromethorphan (25,50 or 75 mg/kg, ip), morphine (50...

The influence of two types of resistant starches (RS2 and RS4) substituted at 10 and 20% in the batter formulation on the water retention capacity of the batter and on the texture, color, fat content and microstructure of the pre-fried and oven cooked breaded black pomfret fillets (Parastromateus niger) were studied. A significant (p<.05) increase of water retention capacity (3-7%) was found i...

&nbsp;Intestinal parasites (IP) are one of the most significant causes of infections among the eldely in developing countries, especially in tropical areas. Trichuris trichiura and Ancylostoma duodenale infect near 2.3 billion people, especially in elderly in all around the world (1). Intestinal protozoan like Giardia lamblia, Entamoeba histolytica and Cryptosporidium parvum are widespread in o...

seasonal variations of climatic parameters are significant in arid and semi-arid regions and sensitivity of each parameter may differ in different seasons. no work has been done in this regard in iran. therefore, in this study, sensitivity analysis of the asce-penman-monteith grass reference evapotranspiration (eto) equation was investigated on the basis of variation of mean air temperature (tm...

Synapses and circuits rely on homeostatic forms of regulation in order to transmit meaningful information. The Drosophila melanogaster neuromuscular junction (NMJ) is a well-studied synapse that shows robust control function. Most prior studies plasticity at the NMJ have centered presynaptic potentiation (PHP). PHP happens when postsynaptic muscle neurotransmitter receptors are impaired, trigge...

In this paper an IP based network consisting of two separate networks - a virtual one, running MPLS and experimental network, connected to the have been studied. VoIP traffic is exchanged between networks. Both are Internet exchange with it. The created by using GNS3. purpose show comparison in performance addition, mathematical distributions approximations made be used further evaluate methodo...
