purpose : to report a case of retained silicone tube case report : we report a case of 48-year-old iranian lady who referred to the department of otolaryngology with 18 years history of epiphora and intermittent mucopurulant discharge from the left lacrimal canaliculi. she had external dacryocystorhinostomy (dcr) with silicon stenting for epiphora 18 years ago but epiphora had continued after s...

Abstract Forest loss due to anthropogenic activities is one of the main causes plant and animal species decline. Studying species’ population status (i.e., density, abundance, geographic distribution) on a regular basis tools assess effect wildlife, monitor dynamics intervene with effective conservation strategies when an endangered declines. On Sulawesi Island, Indonesia, activities, such as a...

The geographical variation in Helicobacter pylori genotypes is an observed phenomenon. Cytotoxin associated genes A (cagA) and E (cagE), and vacuolating cytotoxin (vacA) genotypes of H. pylori are associated with peptic ulcer disease (PUD). This study compared the distribution of these genotypes in Iranian and Afghani isolates and their association with clinical outcomes. H. pylori infected pat...

N owadays, innovation considered as the most important factor, which can affect economic growth extraordinary. Therefore, investigating the effect of variables affecting innovation has priority. In this study, we try to investigate 1) the natural resource curse hypothesis and 2) the effect of institutional quality on the way in which natural resources affects innovation. To investiga...

Motivation: There is growing momentum to develop statistical learning (SL) methods as an alternative to conventional genome-wide association studies (GWAS). Methods such as random forests (RF) and gradient boosting machine (GBM) result in variable importance measures that indicate how well each single-nucleotide polymorphism (SNP) predicts the phenotype. For RF, it has been shown that variable ...
