Large cell acanthoma (LCA) is a benign epidermal tumor that presents with pigmented hyperkeratotic patch well-demarcated boundaries in sun-exposed areas. Since various tumors present overlapping clinical and histopathological features, additional methods to differentiate them would be of great significance. Although there are numerous data on the dermoscopic findings other comparable tumors, la...

As the incompatibilities of the Hering and Young hypotheses of colour vision became more obvious, there occurred to more than one experimenter the idea of devising some intermediate theory which would avoid the pitfalls which the older hypotheses appeared to have encountered.

To detect genomic instability caused by Ac elements in transgenic tomatoes, we used the incompletely dominant mutation Xanthophyllic-1 (Xa-1) as a whole plant marker gene. Xa-1 is located on chromosome 10 and in the heterozygote state causes leaves to be yellow. Transgenic Ac-containing tomato plants which differed in the location and number of their Ac elements were crossed to Xa-1 tester line...
