Rat islet cells in culture are able to form tridimensional aggregates with an architecture and functional activity similar to native islets: pseudoislets. Pseudoislets represent an alternative source for islet transplantation, because their transplant results in a long term allograft acceptance without immunosuppression of the host. Use of pseudois...

Mammalian myoglobins contain two tryptophanyl residues at the invariant positions 7 (A-5) and 14 (A-12) in the N-terminal region (A helix) of the protein molecule. The simultaneous substitution of both tryptophanyl residues causes an incorrect folding with subsequent loss of heme binding. The introduction of a indolic residue in different molecular...

In the present study the mercury concentration has been investigated in three components of a rock pool environment of Genoa Nervi (Ligurian Sea): water, particulate matter and Tigriopus fulvus (Harpacticoid copepod). The influence of some parameters (pH, temperature, salinity, rainfall) on mercury concentration has been evaluated. These data show ...

Expression of human involucrin (hINV) a protein of the cornified cell envelope, was studied in the skin of gasoline storage workers, in order to evaluate the effects of the exposure to petroleum derivatives. A total of 25 forearm skin punch biopsies were carried out. Twenty of which were performed on exposed subjects and five on controls. The speci...

The management of the marine environment and resource exploitation depend on the knowledge of both water conditions and ecological relationships between organisms. In the framework of fishing problems, an adequate food availability is important in order to allow maintaining and growth of fish stocks. The tunny-fishing of Camogli, owing to the coco-...

We studied the involvement of G-proteins in transducing the inductive signal generated by treatment of tibial-derived neonatal rat osteoblasts (ROB) cultured in vitro with FMS*Calciumfluor, a homeopathic preparation utilized in the therapy of osteoporosis. We previously reported that FMS*Calciumfluor acts as inducer and potentiator of osteogenic di...

The skin of road pavers is exposed to a large number of compounds such as asphalt, bitumen, amines, polymers, oils, solvents, sand, gravel, crushed rock, mineral wad, ultraviolet light and heat. In order to verify an up-regulation of HSP27, determined by the above mentioned stimuli, we studied, immunohistochemically, the forearm skin of a sample of...

In this paper, the growth of the marine microalga Tetraselmis suecica was investigated using thermogravimetry (TG) and differential thermal analysis (DTA) to determine suitable diets for larval and juvenile development in aquaculture systems. Microalgae were maintained in synthetic sea water (19@1000 salinity, 18 degrees C constant temperature) and...

Scanning electron microscopy (SEM) techniques can highly contribute to the knowledge of body structures in order to differentiate between different species or between varieties within the same species. This is particularly important in extreme environments, such as in Antarctic waters, where the evolution efforts have promoted the development of en...

In common practice of detecting and recording biomedical signals, it is often implicitly assumed that the propagation, through the whole circuit human body-electrodes recording devices, is frequency and voltage independent. As a consequence, clinicians are not aware that recorded signals do not correspond faithfully to the original electrical activ...
