objective: hla-g is a nonclassical major histocompatibility complex antigen and is expressed as seven isoforms, including four membrane bound (hla-g1 to –g4) and three soluble (hla-g5 to –g7) forms. the pattern of selective expression of hla-g transcripts in tissues shows the existence of a tight transcriptional control on the gene expression. it has been revealed that cytokines including inter...

background systemic lupus erythematosus (sle) is an autoimmune connective-tissue disease involving multiple organs and systems. some evidence has demonstrated that disease activity could be associated with increased risk of organ damage. objectives the aim of this study was to determine the association between systemic lupus erythematosus disease activity index (sledai) scores and subclinical c...

introduction: systemic lupus erythematosus (sle) is an autoimmune disease affect nearly every organ system. pulmonary involvement, which is a common manifestation of sle, can remain undiagnosed if asymptomatic. this study aimed to evaluate the efficiency of spirometric findings in early detection of silent pulmonary involvement and examine its correlation with the six minute walk test in sle pa...

background procalcitonin (pct) levels are increased in sepsis. in most previously conducted research, pct levels were found to increase during septic shock. objectives the purpose of this study was to compare pct levels with crp and esr levels in children with systemic inflammatory response syndrome (sirs), sepsis, and septic shock. methods this cross-sectional study was conducted between decem...

background: oropharyngeal dysphagia following stroke enhances the risk of dehydration, malnutrition, aspiration  pneumonia, persistent disablement, and even death. screening of dysphagia has been shown to positively change health outcomes. the aim of the present study was to systematically introduce the published swallowing screening methods in patients with stroke and  their appropriateness fo...

introduction systemic lupus erythematosus (sle) is a complex autoimmune and inflammatory disease. many studies show hla alleles can be associated with sle. the aim of this study was to determine the association of hla-drb1 alleles with juvenile- onset in iranian children. materials and methods at a case – control study, 31 children with systemic lupus erythematosus (case group) who referred to ...

the purpose of this study was to investigate the potential responses of the cardiovascular system and regional blood flow to hypoxic hypoxia (bb) and to carbon monoxide (co)-induced hypoxia (coh). ten anesthetized cats were studied under two nonnoxic (control: cont) and two hypoxic conditions. four types of radioactive micro spheres were used to measure regional blood flow during cont and two h...
