Growth rate of individually tagged dogwhelks Nucella lapillus (L.) was measured in free-living individuals at 3 sites of differing heavy metal contamination in the Firth of Clyde, west Scotland. Condition index (CI), concentrations of metals (Cd, Cu, Pb and Zn), metallothionein (MT), RNA (the RNA/protein ratio) and glycogen were also measured. In general, the marine environments of Gourock and ...

The people have different behaviour to choose the food, and there are many factors that affect the food choices. The best significant factor to choose the food is taste. Differences in taste perception of several taste modalities are associated to difference in the taste receptors. Polymorphisms of the genes that encoding these taste receptors may clarify this unpredictability in taste percepti...

Centro Trasfusionale e di Immunologia dei Trapianti, Ospedale Maggiore Policlinico, 20122 Milan, Italy Blood samples collected with heparin as anticoagulant have been shown to yield decreased quantities of DNA, and an inhibitory effect of this anticoagulant on PCR has been demonstrated. Furthermore, in our experience, the amplification by PCR of HLA-DRB1 second exon was unsuccessful when the DN...

In the presence of low concentrations (less than 0.5 mM) of hydrogen peroxide Mr 350,000 and 170,000 fragments were generated from plasma and fibroblast medium fibronectins (Fns). No other major fragments were detected when H2O2 concentration was raised or the incubation time prolonged. A 200-300-fold concentration of H2O2 was needed for a complete degradation of the protein. The degradation wa...

Only 9 (11.2%) out of 80 studied bacterial strains were able to utilize iron saturated 2-oxo acids and hydroxyacids and grow on o-phenantroline containing media. These strains belonged to Enterococcus faecalis and Enterococcus faecium species and were isolated from clinical material. Iron sources utilized by all of these strains were Fe(III) complexes with pyruvic, 2-oxobutyric, 4-methylthio-2-...
