One promising field in neurovascular diseases investigation is the use of biomarkers to guide stroke etiology diagnosis and classification. Since treatment differs among etiologic subtypes and nowadays many patients receive a diagnosis of undetermined stroke, biomarkers might become an important additional diagnostic tool. In this review we update current knowledge about biomarkers related with...

background : avian influenza virus (aiv) infection is a major cause of bird and human morbidity and mortality. we aimed to evaluate a specific and sensitive multiplex rt-pcr that can simultaneously detect influenza type a viruses and differenti­ate the two most important subtypes of avian influenza viruses h7 and h9 subtypes. methods : a multiplex reverse transcriptase-polymerase chain reaction...

Background and aim: Basal cell carcinoma (BCC) is the most common skin cancer in white-skin populations. Recent studies suggest that BCC is not a single entity and different histological subtypes show different clinical behavior and might have different etiology. The aim of this study was to assess differences in age, sex, site of distribution and proliferative activity in histological subtypes...

background the relationship between biomarkers and imaging features is important because imaging findings can predict molecular features. objectives to investigate the relationship between clinicopathologic and radiologic factors and the immunohistochemical (ihc) profiles associated with breast cancer. patients and methods from december 2004 to september 2013, 200 patients (mean age, 56 years; ...

Objective(s) Human papillomavirus (HPV) infections are related to the genesis of various benign lesions and some malignant tumors, but no clear relationship has been identified so far between the subtypes of HPV and skin tag. Materials and Methods The present case-control study was designed to detect the existence of low risk and high risk HPV types in lesions of 50 patients with skin tag (c...

Objective: Illness Anxiety Disorder (IAD) has two subtypes, care-seeking type, and care-avoidant. There is little information about the differences between the two subtypes.  Methods: This study was carried out to compare perfectionism and tolerance of ambiguity in the subtypes of the IAD. To this end, a causal-comparative design was employed. The statistical population of the study included t...

the culture results of 203 cases with different wounds were studies 150 of the latter were burn cases (mainly second and third degree burns), and 53 were of other types (surgical, traumatic, ect). four subtypes of bacillus cereus were isolated upon culture, and the different toxins produced in dht broth with 0.1% glucose were assessed. the lethal toxin was injected intravenously to syrian rats,...

background and objective: helicobacter pylori has several strains with different degrees of virulence. the aim of this study was to detect two major important virulence factors, caga/vaca genotypes, and to determine correlations among different caga/vaca genotypes and histological features of chronic gastritis in iranian patients. methods: in this cross- sectional study, gastric biopsy was take...
