Artificial versus Natural Dyes

The effect of artificial reefs on fish assemblage versus natural sites in the Bandar Lengeh-Iran

  Artificial reefs are used to compensate the destruction of marine ecosystems. In the present study, the effects of artificial reefs were compared to natural sites. For this purpose, five treatments including four different forms (Reef ball (R), Laneh Mahi (L), used materials (U) and R+L+U) of artificial reefs and one control were established. The reefs were deployed at Bandar Lengeh, the Pers...

The New Genetics and Natural versus Artificial Genetic Modification

The original rationale and impetus for artificial genetic modification was the “central dogma” of molecular biology that assumed DNA carries all the instructions for making an organism, which are transmitted via RNA to protein to biological function in linear causal chains. This is contrary to the reality of the “fluid genome” that has emerged since the mid-1970s. In order to survive, the organ...

Natural and synthetic dyes in histology

Counterstains can be of high relevance for the evaluation of immunostaining because cellular details and immunological reactivity are often easier correlated in counterstained tissue sections than in simply immunostained specimens. There are many kinds of dyes in histology. Some are useful for counterstainings while others are not; a careful selection is necessary. Even a given type of dye, f.e...
