Cadmium and copper metallothioneins in the American lobster, Homarus americanus.
Lobsters were fed cadmium-rich oysters for 28 days, and the induction of cadmium metallothionein and its relation to concentrations of cadmium, copper, and zinc in the digestive gland and gills was determined. A portion of the tissues also was retained for determining the cytosolic distribution of these metals by gel filtration and ion-exchange chromatography. The digestive gland contained a ma...
متن کاملThe exoskeleton of the lobster Homarus americanus as an example of a smart anisotropic biological material.
Many biological materials are composed of fibrils arranged according to well-ordered three-dimensional patterns. These materials often show a strong anisotropy in their properties. An essential characteristic of biological structures is their hierarchical organization from the nanometer to the millimeter scale. Lobster cuticle is a good example of this and a suitable model for studying these pr...
متن کاملThe olfactory pathway for individual recognition in the American lobster Homarus americanus.
Individual recognition in the lobster Homarus americanus (Milne-Edwards), is based on detection of urine pheromones via chemoreceptors of the lateral antennular flagellum. The specific sensory pathway mediating this recognition is not known. Most of the chemoreceptor cells of this flagellum are found in the unimodal aesthetasc sensilla and project specifically to the glomeruli of the olfactory ...
متن کاملGross Dissection of the Stomach of the Lobster, Homarus Americanus
The stomach of the American lobster (Homarus americanus) is located in the cephalothorax, between the rostrum and the cervical groove. The anterior end of the stomach is defined by the mouth opening and the posterior end by the bottom of the pylorus. Along the dorsal side of the stomach lies the stomatogastric nervous system (STNS). This nervous system, which contains rhythmic networks that und...
متن کاملRecognizing Incipient Epizootic Shell Disease Lesions in the Carapace 2 of the American Lobster, Homarus americanus
Causal factors leading to Epizootic Shell Disease (ESD) lesions in American Lobster, H. 20 americanus, are not well understood. We explore the structural and physiological bases for 21 development of ESD from preclinical stages invisible to unaided eye to early visible stages. We present 22 a lobster shell model which develops structural functional vulnerability and suggests plausible routes to...
