11. Internal epithelia on the other hand more often rely on tight junctions for their barrier function . 12. The two most common types of barrier functions are inverse barrier functions and logarithmic barrier functions . 13. The two most common types of barrier functions are inverse barrier functions and logarithmic barrier functions. 14. This continuously shed outer layer of the epidermis performs the main barrier function of the skin. 15. APC supports endothelial barrier function and reduces chemotaxis. 16. The impaired skin barrier function commonly leads to localized infection, which sepsis and death may follow. 17. Such thinning impairs its barrier function and allows transepidermal water loss that can lead to skin irritation. 18. Resumption of interest in logarithmic barrier functions was motivated by their connection with primal-dual interior point methods. 19. A barrier function , now, is a continuous approximation to that tends to infinity as approaches from above. 20. The C-terminus domain has been shown experimentally to be required for correct assembly of tight junction barrier function .
