ABSTRACT
Objective: To review the prevalence of cryptosporidiosis among animal population of Iran. Methods: Data were systematically gathered from 1 January 2000 to 1 January 2020 in the Islamic Republic of Iran from the following electronic databases: PubMed, Springer, Google Scholar, Science Direct, Scopus, Web of Science, Magiran, and Scientific Information Database (SID). According to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) and inclusion criteria, 88 eligible studies were obtained. Results: The pooled prevalence of cryptosporidiosis using random and fixed effects model according to heterogeneity among animals was as follows: rodents 18.8% (95% CI 12.6%-25.0%), camels 17.1% (95% CI 8.6%-25.7%), cattle 16.8% (95% CI 13.4%-20.1%), goats 14.1% (95% CI 5.2%-23.0%), horses 12.2% (95% CI 8.3%- 16.2%), birds 10.5% (95% CI 7.6%-13.4%), sheep 9.9% (95% CI 2.4%-4.9%), cats 8.8% (95% CI 4.8%-12.8%) and dogs 3.7% (95% CI 7.0%-12.8%). Conclusions: Cryptosporidiosis has been reported and present in a wide range of animals in Iran over the years and has a high prevalence in most of these species.
ABSTRACT
Therapeutic targeting of phosphatidyl-inositol 3-kinase [PI3K] is considered as a possible strategy in several types of cancer, including gastrointestinal ones. In vitro and in vivo studies indicated the significance of proapoptotic and antiproliferative inhibition of PI3K. Although there are many phase 1 and 2 clinical trials on PI3K inhibitors in patients with gastrointestinal cancer, the molecular mechanism of PI3K targeting PI3K/ mTOR pathway is not clear. Panclass I, isoformselective, and dual PI3K/mTOR inhibitors are under investigation. This review aimed to indicate PI3K-dependent targeting mechanisms in gastrointestinal cancer and the evaluation of related clinical data
