Expression and cellular localization of the Nef protein from human immunodeficiency virus-1 in stably transfected B-cells.

1992

Nef protein, encoded by the regulatory nef gene of human immunodeficiency virus type 1 (HIV-1), was expressed in the B-cell line Raji. The cells were stably transfected with plasmids containing the nef transcriptional cassette. They expressed Nef with an Mr of 27,000; the yield could be augmented by incubation with the tumor promoter 12-O-tetradecanoylphorbol-13-acetate. The intracellular localization of Nef was analyzed applying immunofluorescence microscopy using a confocal laser scanning microscope. The antigen was stained with a monoclonal antibody directed against the N-terminal part of Nef. The experiments revealed that in non-dividing cells Nef is present both in the cytoplasm and th…

Recognition of water masses according to geochemical signatures in the Central Mediterranean sea: Y/Ho ratio and rare earth element behaviour

2007

This study reports the results of geochemical investigations carried out in the Strait of Sicily (Central Mediterranean Sea) during the oceanographic cruise BANSIC 2000, focusing on the area around the Pantelleria Island. We evaluate the interface processes between dissolved phase and suspended particulate matter in the water columns on the basis of Y/Ho ratio and rare earth elements and yttrium distributions that are suitable to trace the occurrence of different water layers in Central Mediterranean Area. The main source of trace elements to the sea water system was recognized in the atmospheric fallout, while different scavenging mechanisms among Y and rare earth elements occur. Cation ex…

Achievement of thermotolerance through hsps phosphorylation in sea urchin embryos.

1995

TPA treatment of sea urchin embryos is able to induce thermotolerance. Evidence is provided that TPA treatment induces phosphorylation of a constitutive stress protein of 38 KDa.

Apoptosis in sea urchin embryos.

1997

Abstract It is demonstrated by DNA electrophoresis analysis, morphological observations and TdT in situ reaction, that Paracentrotus embryos if treated with TPA plus heat undergo an apoptotic reaction. Indication is also obtained that non treated embryos undergo spontaneous apoptosis at the early pluteus stage, expecially in the districts of arms and intestine. The possible meaning of this latter observation is discussed.
