Introduction: Nurses are the largest group of care providers in the health care system. Therefore, In the field of health services, the quality of care among the nurses is considered as one of the most important factors. Methods: The present study was a descriptive correlation with the structural equation modeling approach. The study population consisted of 393 nurses of public hospitals in B...
Adenosine has many of the characteristics of a regulator of cerebral blood flow and adenosine receptors change in morphine dependency. In this study the changes in adenosine receptors' responsiveness of pial vessels in the hind limb area of the sensory cortex were evaluated in morphine dependent rats (MDR) using the laser Doppler flowmetry technique. Adult male Sprague Dawley rats (250-350 ...
Mestastatic prostate cancer cells (MPCCs) frequently metastasize to bone, which is a “favorite soil” for colonization and proliferation of MPCCs. Prostate cancer bone mestastasis is tightly associated with tumor-induced bone lesions, most commonly caused from the etiological imbalance between osteoblastic bone formation and osteoclastic bone resorption, and from the anti-tumor immune response. ...
Introduction: 3-4, methylenedioxymethamphetamine (MDMA) causes apoptosis in nervous system and several studies suggest that oxidative stress contributes to MDMA-induced neurotoxicity. The aim of this study is to examine the effects of N-acetyl-L-Cystein (NAC) as an antioxidant on MDMA-induced apoptosis. Methods: 21 Sprague dawley male rats (200-250mg) were treated with MDMA (2×0,5mg/kg) or MDMA...
Osteoporosis is a systemic skeletal disease and there is a close relationship between the sympathetic nervous system (SNS) and bone metabolism. Leptin has been shown to regulate bone formation and bone resorption via the SNS. However, the effect of SNS on leptin signaling has not been clearly understood. In the present study, we studied the effect of propranolol on ovariectomy-induced osteoporo...
Background: Leptin, a 16-KDa peptide hormone secreted from theadipose tissue, plays an important role in the regulation of energyintake and expenditure and body weight regulation; furthermore,it has a regulatory function on the reproductive system. The aimof this study was to assess the relationship between serum leptinlevels and sex hormones in psoriatic patients and control groupand to determ...
The liquidity crisis in 2008 sparked interest in the role of regulation that could promote resilience and stability in the banking system. While the Public Interest theory suggests that legal policies could discipline banking activities, the Private Interest theory predicts otherwise, which impairs banking performance. The conflicting theories warrant comprehensive research, especially for Isla...

The statistical population of this study included all the addicts hospitalized in addiction treatment centers in West Azerbaijan Province who had been admi...
due to lack of knowledge management system in the organization of technical and vocational university of iran (tvuni) and losing good employees because of retirement and substitution causes huge amount of costs to replace the similar expertise. there is no any suitable system in the tvuni to store, to document, and to distribute knowledge. based on the university’s features such as it has diffe...
In this paper, chaotic dynamic and nonlinear control in a glucose-insulin system in types I diabetic patients and a healthy person have been investigated. Chaotic analysis methods of the blood glucose system include Lyapunov exponent and power spectral density based on the time series derived from the clinical data. Wolf's algorithm is used to calculate the Lyapunov exponent, which positive val...
