abstract background: normal standard references of blood pressure (bp) for children and adolescents should be constructed according to anthropometric indices. therefore , we aimed to produce bp reference percentiles by body mass index (bmi). methods: data on demographic characteristics, anthropometric indices and bp values of 16246 3-18-year-old children and adolescents from 3 cross-sectional s...

conclusions respiratory distress is more common in eos whereas jaundice, fever and seizure are more likely to be observed in los infants. considering the results, clinical manifestations should be regarded as an important part of early diagnosis of sepsis. objectives the aim of this study was to evaluate, record and rank the clinical manifestations and lab data of neonates with clinical sepsis....

background: atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. oxidized low-density lipoprotein (oxldl) is considered as an important determining factor in the pathogenesis of atherosclerosis. objective: the purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

background: tumor necrosis factor alpha (tnf-α) is a primary mediator of immune regulation and might be required in the early stages of dc development from cd34+ cells. however, details of optimal timing of exposure to tnf-α in dc development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of dcs remain to be valid...

background: investigation of toxicity of silver nanoparticle, especxially blood toxicity, is necessary because this nanoparticle is used a lot in diffrerent parts of life and invironment. the aime of this is evaluation the effects of silver nanoparticles with different concentrations on blood cells pregnant wistar rats. materials and methods: in this case control study, 30 pregnant rat were div...

background the aim of this study was the ex vivo expansion of umbilical cord blood hematopoietic stem cells on biocompatible nanofiber scaffolds. materials and methods cd133+ hematopoietic stem cells were separated from umbilical cord blood using midimacs (positive selection) system by means of monocolonal antibody cd133 (microbeads) subsequently, flowcytometry method was done to assess the pur...

conclusions in a current study based on increasing maternal age, the hdl-c level in cord blood was decreased which is an independent risk factor for cvds in adulthood. results a statistically significant negative correlation was observed between cord blood hdl-c and maternal age (r = -0.18, p <0.01). there was no relationship between other lipids and lipoproteins with maternal age. our findings...

background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...

background: mr imaging is one of the best diagnostic modalities in medicine. during an mr imaging examination, three types of field are employed to produce images. various experimental studies have been performed about the effects of each single type of field but only few studies are available on their combination to generate mr imaging. the main objective of this research work is to study the ...
