isolation and differentiation of various species of mycobacteria are predominantly based on conventional, cultural and biochemical tests. among the non-tuberculous mycobacteria, these tests are unable to differentiate m. scrofulaceum from m. avium-intracellulare (mai) because of their identical biochemical characteristics. for this reason, one hundred mycobacterial strains suspected to be m. sc...

acquaintance with the different anatomical variations of the arterial supply of the gallbladder is of great importance in hepatobiliary surgical procedures. a rare variation of the hepatobiliary arterial system was found during anatomical dissection of a female iranian cadaver. two cystic arteries were present, the first arising directly from the right hepatic artery and the second from the gas...

background: hepatitis b virus potentially accelerates graft rejection and mortality in renal transplantation population. vaccination of graft candidates without prior immunization against hbv seems essential before transplantation but some candidates of transplantation have not received hbv vaccine at the time of receiving graft. we aimed to evaluate immunogenicity of an enhanced regimen (4 dos...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...

purpose: to describe a new noninvasive method to assure correct orientation of donor lenticules in descemet stripping automated endothelial keratoplasty (dsaek) surgery. methods: dsaek surgery was performed in three eyes with the diagnosis of pseudophakic bullous keratopathy (pbk). for the laboratory part of the study, two whole globes and two precut corneoscleral buttons were used. the donor l...

a dynamic two dimensional problem of thermoelasticity with double porous structure has been considered to investigate the disturbance due to normal force and thermal source. laplace and fourier transform technique is applied to the governing equations to solve the problem. the transformed components of stress and temperature distribution are obtained .the resulting expressions are obtained in t...

‎highest weight modules of the double affine lie algebra $widehat{widehat{mathfrak{sl}}}_{2}$ are studied under a‎ ‎new triangular decomposition‎. ‎singular vectors of verma modules are‎ ‎determined using a similar condition with horizontal affine lie‎ ‎subalgebras‎, ‎and highest weight modules are described under the‎ ‎condition $c_1>0$ and $c_2=0$.

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

background: this study was done to determine the prevalence of publication misconduct among iranian authors. methods: data were collected through an email survey of corresponding authors of papers published in iranian journals indexed in scopus during 2009-2011. using the double list experiment, these individuals were indirectly questioned about committing one of the five misconducts including ...

background : approach to the small intestine has been difficult even with newer methods. double-balloon enteroscopy (dbe) has been created for diagnostic and therapeutic interventions in diseases of the small intestine. small intestinal diseases have different etiologies in each country. the dbe has been introduced in recent years in iran. our aim was to study the indications and results of dbe...
