The timing of morphogenetic events in the regenerating forelimb of the axolotl was investigated by rotation of limb coverings at well-defined stages in the regenerative process. Both the skin covering the stump and the epidermis covering the regenerate were manipulated independently and together as a unit. The results show that the transmission of morphogenetic information covers a broad range ...

The skin covers our entire body and is said to be the “largest organ of human body”. It has many health-maintaining functions, such as protecting from ultraviolet rays dryness maintaining temperature through energy metabolism. However, number patients suffering diseases, including atopic dermatitis, increasing due strong irritation caused by detergents that are spread development chemical indus...

A vertex cover of a graph G=(V,E) is a subset N of V such that each element of E is incident upon some element of N, where V and E are the sets of vertices and of edges of G, respectively. A connected vertex cover of a graph G is a vertex cover of G such that the subgraph G[N] induced by N of G is connected. The minimum vertex cover problem (VCP) is the problem of finding a vertex cover of mini...
