Endothelin receptor B subtype 2 (EDNRB2) is a seven-transmembrane G-protein coupled receptor. In this study, we investigated EDNRB2 gene as a candidate gene for duck spot plumage pattern according to studies of chicken and Japanese quail. The entire coding region was cloned by the reverse transcription polymerase chain reaction (RT-PCR). Sequence analysis showed that duck EDNRB2 cDNA contained ...

Detailed geological models typically contain many more cells than can be accommodated by reservoir simulation due to computer time and memory constraints. However, recovery predictions performed on a coarser upscaled mesh are inevitably less accurate than those performed on the initial fine mesh. Recent studies have shown how to use both coarse and fine mesh information during waterflooding sim...

background and aims: to evaluate the effect of temperature on wheat streak mosaic virus (wsmv) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using adl-cross (resistant) and marvdasht (susceptible) cultivars. materials and methods: results showed that incubation at 32c changed the gene expression for resistance ...

The effects of attention on the responses of visual neurons have been described as a scaling or additive modulation independent of stimulus features and contrast, or as a contrast-dependent modulation. We explored these alternatives by recording neuronal responses in macaque area MT to moving stimuli that evoked similar firing rates but varied in contrast and direction. We presented two identic...

African penguins (Spheniscus demersus) carry a pattern of black spots on their chests that does not change from season to season during their adult life. Further, as far as we can tell, no two penguins have exactly the same pattern. We have developed a real-time system that can confidently locate African penguins whose chests are visible within video sequences or still images. An extraction of ...
