The paper presents the effects of nucleus accumbens destruction in rats. There are certain behavioral correlates (e.g., avoidance learning and dominance) which are influenced by the destruction of the nucleus accumbens, while other specific correlates are not significantly affected (namely, open field movements and competition for food). The results are… (More)
OBJECTIVES To compare the performance of immediate colposcopy, repeat Pap test and HPV test as triage options for women diagnosed as having atypical squamous cells of undetermined significance (ASC-US) while attending organised screening for cervical carcinoma in five centres of the Veneto region. METHODS Women consecutively diagnosed as having ASC-US… (More)
It was demonstrated that the previous in vitro electrical stimulation of human and rat platelet-rich plasma does not modify the subsequent response of platelets to the aggregating activity of ADP, thrombin, thrombofax or adrenaline. This is interesting in view of the fact that the electrical stimulation can induce clot retraction.
The ionophore for divalent cations, A 23187, induces plate aggregation and clot retraction. Acetylsalicyclic acid has a potentiating effect on the aggregation induced by A 23187 in platelet-rich plasma, while it inhibits the aggregation of washed platelets. Acetylation of plasma proteins could be the reason of the increased platelet aggregation induced by A… (More)
Pure synthetic platelet aggregating factor (PAF) (1-O-Hexadecyl-2-acetyl-sn-glycero-3-phosphorylcholine) induces a dose-dependent platelet aggregation in platelet-rich plasma (PRP) and in gel-filtered platelets. Irreversible platelet aggregation was observed at final concentrations of PAF higher than 2 X 10-(7) mol/l, while reversible or two-wave… (More)
