Background: Many of lay person believe that opium lowers blood glucose. However some studies show the opposite results. In this study, we tried to evaluate the effect of opium on blood glucose and insulin resistance. Methods: This comparative study including 53 addicts in case groups who used opium just in the form of smoking and 55 non-addicts in a control group, took part in the study, after ...
Obesity is often associated with leptin resistance, which leads to a physiological system with high leptin concentration but unable to respond to leptin signals and to regulate food intake. We propose a mathematical model of the leptin-leptin receptors system, based on the assumption that leptin is a regulator of its own receptor activity, and investigate its qualitative behavior. Based on curr...
In this paper, we develop a mathematical model of sprinting in which anaerobicmetabolism is included. This model is simplified by considering the broad changes of energy leveland the cyclic variation associated with the strike pattern. We consider the effect of the centre of massto the overall energy balance along with force of resistance during initial motion of body. Results areobtained for t...

PURPOSE OF REVIEW Currently, antiviral resistance is a major public health concern. Here, we review how mathematical models have been used to provide insights into the emerging threat of antiviral resistance. We focus mainly on the problem of drug resistance to HIV. RECENT FINDINGS We review how antiviral models of HIV have been used: (1) to understand the evolution of an epidemic of drug-res...
salmonella enterica is recognized as one of the major food-borne pathogens with more than 2,500 serotypesworldwide. the present study addresses antimicrobial resistance of salmonella enterica serovar enteritidisisolates in iran. a collection of 151 salmonella spp. isolates collected from poultry were serotyped toidentify salmonella enteritidis. sixty-one salmonella enteritidis were subsequently...
For most vessels, the frictional resistance of the hull in the water has the largest share in the total resistance of the ship, so in the past few decades much research have been done on reducing the frictional resistance of ships. Among these, stepped vessels with a significant reduction in the amount of wetted surface have a special place. In this study, the effect of a single transverse-step...
In economic arena, Islamic republic of Iran is facing issues and concepts never experienced before, theoretically or practically, by anyone anywhere. Therefore Islamic republic of Iran is itself obliged to innovate, theorize and create its own models in these novel economic situations. Among these concepts is resistance economy. Having been proposed by supreme leader, it includes a large number...
Background and Objectives: Osteocalcin plays an important role in stimulating of insulin secretion from pancreatic β-cells. Therefore, the present study aimed to determine the effect of aerobic and resistance exercises on serum osteocalcin, insullin resistance and beta cells function in overweight men. Materials and Methods: In this clinical trial study conducted in Ahar in summer 2018, 40 ove...
rutting of hot mix asphalt pavements due to increased number of heavy vehicles, especially in tropical regions, causes several performance problems. large stone asphalt mixtures have more stiffness and shear resistance and so more rutting resistance compared to conventional mixtures. hence, using these mixtures in thick layers of hot mix asphalt pavements at tropical regions could be an appropr...
