The enteric nervous system (ENS) derives from neural crest, which invade and migrate along the developing gut, proliferate extensively, and differentiate into neurons and glial cells organized as interconnected ganglia that control complex behaviours of the gut, such as peristalsis. While most ENS progenitors undergo differentiation, cells exhibiting properties of enteric progenitor cells (EPCs...

Nuage, a well conserved perinuclear organelle found in germline cells, is thought to mediate the repression of retroelements in Drosophila melanogaster by regulating the production of Piwiinteracting RNAs (piRNAs). Here, we present evidence that the nuage/piRNA pathway components can be found in cytoplasmic foci that also contain retroelement transcripts, anti-sense piRNAs and proteins involved...

spatial patterns are useful descriptors of the horizontal structure in a plant population and may change over time as the individual components of the population grow or die out. but, whether this is the case for desert woody annuals is largely unknown. in the present investigation, the variations in spatial patterns of tribulus terrestris during different pulse events in semi-arid area of the ...

this study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. the study was carried out in steppe rangelands of saveh, markazi province, iran. four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. to study various vegetation and...

we report on the synthesis, morphology, chemically and structurally of tio2-cuo-sio2 nanostructure with different precursors molar ratio and calcined temperatures. in the present work, ternary reactive powders in the tio2-cuo-sio2 systems have been obtained using the sol-gel method, by the simultaneous gelation of all cations. the compounds and other elements change in special chemical and phys...

The aim of this study is to compare the somatotype male running Ultra-trail race at different distances and evaluate performance relationship. A total 44 runners, average age 45.64 ± 9.16 years; height 175.84 6.18 cm; body weight 75.36 7.46 kg, who ran 13 km (n= 6), 30 19), 66 14) 100 5), participated voluntarily in study. Heath & Carter method was used determine somatotypes runners. ti...

Abstract Background Immune checkpoint inhibitors (CPI) have revolutionised cancer treatment, with previously untreatable disease now amenable to potential cure. Combination regimens of anti-CTLA4 and anti-PD-1 show enhanced efficacy but are prone off target immune-mediated tissue injury, particularly at the barrier surfaces. CPI-induced colitis is a common serious complication. Methods To probe...
