The morphology of the normal bovine fetal gut has receivec little attention. A more detailed knowledge of its structure is necessary to serve as a basis for studies of pathologic changes in the fetal gut and early postnatal gut in this species. The development of Peyer’s patches, argentaffin cells, and Paneth cells was studied in the bovine fetuses. These were selected because they represent sp...

interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

Background: Different modalities have been tried in order totreat stable vitiligo. Culturing melanocytes is time consumingand expensive. Therefore, new methods using autologousmelanocytes are sought. We aimed to compare the mixed nonculturedautologous melanocytes of the outer root sheath andthe bulge area of hair follicle transplantation plus dermabrasionwith dermabrasion alone in stable genera...

we showed that alignment performance in a three-Gabor alignment task was impaired when patches which were oblique to the stimulus configuration were employed, rather than patches which were orthogonal or collinear. As part of this study we showed that for a wide range of configurations (all vertical, all horizontal , inner vertical with outer vertical, inner horizontal with outer horizontal) th...
