BACKGROUND The presence of low complexity and repeated regions in genomes often results in difficulties to assemble sequencing data into full chromosomes. However, the availability of full genome scaffolds is essential to several investigations, regarding for instance the evolution of entire clades, the analysis of chromosome rearrangements, and is pivotal to sexual crossing studies. In non-con...

conclusions the homemade kit, compared with the imported kit and biopsy-proven tests may be a valid and reliable method for determining the presence of h. pylori infection in iran. background current diagnosis of helicobacter pylori infection by biopsy-based tests requires invasive sampling. non-invasive methods such as the h. pylori stool-antigen (hpsa) test may be the best alternative for dia...

Skidding operations induce changes in soil physical properties, which have the potential to impact soil sustainability and forest productivity. Our objective was to investigate the effects of traffic frequency, trail slope, and soil moisture content on soil compaction, total porosity and rut depth. Treatments included a combination of three different traffic intensities (3, 7, and 14 passes), t...

Homeostasis is the ability of physiological systems to regain functional balance following environment or experimental insults and synaptic homeostasis has been demonstrated in various species following genetic or pharmacological disruptions. Among environmental challenges, homeostatic responses to temperature extremes are critical to animal survival under natural conditions. We previously repo...

BACKGROUND Epidemiology of diseases changes over time with changes in socio-economic status, culture and health care systems. Gastroesophageal reflux disease (GERD) and peptic ulcer disease (PUD) are among the diseases whose epidemiology has changed over the past few decades in the west. Studies addressing the trend of GERD and PUD occurrence in Iran are lacking. We aimed to look at the time tr...
