materials and methods the expression of gp73 was investigated in 88 cancerous and self-control non-cancerous tissues using tissue microarrays with immunohisto- chemistry and was confirmed by western blotting. circulating gp73 levels were detected in the sera of 281 patients with liver diseases using enzyme-linked immunosorbent assay. results the levels of circulating gp73 expression in the hcc ...

enteritis due to campylobacter is the most common cause of acute bacterial diarrhea worldwide. in most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. campylobacters are saccharolytic and fastidious bacteria. these traits limit the number of available biochemical tests by which isolates may be differentiated. these limitations might, in...

background: studies have demonstrated that sickle cell trait can be found in an asymptomatic healthy carrier with normal complete blood count (cbc) and red blood cell (rbc) indices. according to iranian ministry of health bulletin instructions, prenuptial thalassemia screening program (tsp) primarily depends on rbc indices which are measured through a routine cbc. only when these levels are bel...

background: the clinical diagnosis of meningitis is crucial, particularly in children. the early diagnosis and empiric an­tibi­otic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16srdna frag­ment which is produced by universal primers led up fast and sensitive determination. the purpose of this study was to investi­gate a rapid method fo...

background: hla b27 is a sub class of human leukocyte antigen (hla) class i molecule. it was known as the first genetic risk factor associating with ankylosing spondylitis (as). allele frequency of hla-b27 alleles is different across populations. the present study is aimed to investigate the prevalence of hla-b27 in patients referred to danesh clinical laboratory during 2014 to 2015. methods an...

background in the last two decades the incidence of sexually transmitted infections (stis) are dramatically increased and remain a major public health problem in developing countries. trichomoniasis is the most common non-viral sexually transmitted infection caused by trichomonas vaginalis which is a flagellated protozoon associated with vaginitis, cervicitis and urethritis. researchers believe...

background: osteopoikilosis (opk) is a rare inherited condition of the bones, transmitted as an autosomal dominant trait characterized by numerous hyperostotic areas that tend to localize in periarticular osseous regions. it is usually asymptomatic and is often diagnosed incidentally during x-rays made by other reasons. we present a case of 34-year-old man suffering from polyarthralgia and low ...
