Integrins are heterodimeric cell-surface receptors with key functions in cell-cell and cell-matrix adhesion. Integrin α and β subunits are present throughout the metazoans, but it is unclear whether the subunits predate the origin of multicellular organisms. Several component domains have been detected in bacteria, one of which, a specific 7-bladed β-propeller domain, is a unique feature of the...

during 1979-77 a large number of kurdish populations in northern part of iraq temporarily immigrated to iran and settled in dezful area of khuzestan province, south-west iran. faecal examination of 3,263 samples for intestinal metazoan parasites and 1,154 urine samples for detecting schistosoma haematobium, infection were performed in different sex and age groups. the percentages of prevalent i...

Cnidarians display most of the characters considered as milestones of metazoan evolution. Whereas a tissue-level organization was probably already present in the multicellular common ancestor of all animals, the Urmetazoa, the emergence of important animal features such as bilateral symmetry, triploblasty, a polarized nervous system, sense organs (eyes, statocysts), and a (chitinous or calcium-...

With the birth of next-generation sequencing (NGS) technology, genomic data in public databases have increased exponentially. Unfortunately, exogenous contamination or intracellular parasite sequences assemblies could confuse analysis. Meanwhile, they can provide a valuable resource for studies host-microbe interactions. Here, we used strategy based on DNA barcodes to scan protistan GenBank WGS...
