1996The economic performance of Sub-Saharan Africa (SSA) over the past two decades has been disappointing. The initial explanation for this poor performance focussed on deficient macroeconomic policies. However a number of SSA countries have undertaken and sustained a reasonable measure of macroeconomic reform and still see no significant expansion in the ...

Structure and function of the epidermal barrier
American Journal of Infection Control, 2006The skin is divided into 2 main structural layers: the epidermis and the dermis. The epidermis is generally considered to be subdivided into 5 separate strata: basal, spinous, granular, lucid, and corneum. The vital barrier function of the skin resides primarily in the top stratum of the epidermis, the stratum corneum (SC). The SC is the barrier to the

Structural Features of Barrier Membranes
2000Most cell membranes are surprisingly permeable to water and small uncharged solutes. This property is a consequence of both the fluid and anisotropic nature of the phospholipid bilayer. Water molecules are able to partition into the proximal region of the hydrocarbon core and then diffuse across the bilayer before dissolving in the aqueous environment ...

Skin Barrier: Structure and Function
1988Two major biological roles of the epidermis as the interface between the interieur of the body and the environment can be defined: the barrier function and the role as a transporting surface. According to the immediate environment, the balance between these two functions has changed during evolution.
