conclusions the results of our study show that serum zinc level in bronchiectasis patients was lower than the control group and the difference was statistically significant. it seems that the use of zinc supplement can reduce progression of the infectious disease regarding its role in improving the immune system reactions and some unknown mechanisms. therefore, prophylactic and therapeutic use ...

the results showed success of the health system to detect suspected cases of the measles and appropriate sampling from suspected cases that were more than expected. in addition, per every one million population of iran in 2014, 1.27 of cases of measles were reported; that a numbers of confirmed cases observed in afghan refugees. low levels of immunization coverage in eastern neighboring countri...

results the stool samples were examined via direct microscopic examination and acid-fast staining. positivity was determined in 129 (5.7%) cases. in the overall assessment of the patients with respect to general body itching, rectal itching, allergy, immunosuppression plus cancer, shortness of breath, ulcerative colitis, diarrhea, abdominal pain, salivation, constipation, nausea, vomiting, grow...

Epilepsy is accompanied with a strong change in neuronal activity not only in excitatory (glutamatergic) and inhibitory (GABAergic) neurotransmission, but also in neuromodulatory agents. Dopaminergic system, as an important neuromodulatory system of the brain, has significant effect on neuronal excitability. In addition, this system undergoes many changes in epileptic brain. Understanding the e...

statement of problem: microorganisms are essential for the development of periradicular diseases and are one of the major causative factors associated with endodontic treatment failures. different instruments and preparation techniques have been developed in endodontics to eliminate or reduce intracanal bacteria. purpose: the aim of this study was to compare the amount of remaining e. faecalis ...

this paper discusses the control of flexible microgrids, consisting of a redox flow batteries (rfb) and a new power conditioning system (pcs) for the rfb. considering the importance of energy storage, this study is essential in power systems that are developed cautiously. rfb is connected to power system by a dc/dc or dc/ac converter to produce a dc voltage. it is very important that this conve...

in this paper mathematical structure of time-dependent lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent lagrangian systems are considered. starting point is time-independent lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to the...
