In this study, the adsorption of certain water-soluble cationic dyes, (basic blue 9, basic blue 12, basic blue 17, brilliant cresyl blue, janus green B, basic green 4, basic violet 1, basic violet 3, and thionin) onto TriSyl silicas by batch adsorption at 25◦C was investigated. In the adsorption experiments, Langmuir type adsorption in the Giles classification system was found. Binding paramete...

In an attempt to clarify the mechanism of production of the syndactyly induced by Janus Green B (JGB) we have studied the morphology and structural modifications of the chick embryo leg bud after JGB administration by means of neutral red vital staining, whole-mount cartilage staining and light microscopy and transmission and scanning electron microscopy. The results show that the well-known in...

The freshwater fish Ancistrus brevifilis, which is found in Venezuelan rivers, is considered a potential sentinel fish in ecotoxicological studies. The cadmium (Cd) effect on the mitochondrial viability (MV) and acid soluble thiols levels (AST) in A. brevifilis tissues (liver, kidney, heart, and gill) was evaluated. Forty-two fish with similar sizes and weights were randomly selected, of which ...

We present a novel, versatile, and simple solution-based routine to produce soft, nanosized Janus particles with tunable structural and physical properties at high volume yield. This process is based on the cross-linking of compartments within precisely defined multicompartment micelles (MCMs), which are themselves formed by the self-assembly of ABC triblock terpolymers. Therein, the C blocks f...

Laser micro-irradiation of cell inclusions has become a useful method in cell biology (1). A pulsed ruby laser microbeam system has been successfully used to study morphological and functional relationships within mitochondria of tissue culture cells vitally stained with Janus green B (2-6) . Recently, an argon ion gas laser microbeam has been used to place lesions on mitotic chromosomes of sal...
