After a case of Angiostrongylus vasorum (canine lungworm) was diagnosed in the province of Chieti (Italy) in early 2008, parasitological research was conducted to investigate the presence of the parasite in dogs in the area. A total of 178 dogs, 56 carcasses and 122 stool samples were examined between January and September 2008. The carcasses were examined(More)
Human placental transferrin receptor (HPTR), purified following a procedure based on affinity chromatography step, was reconstituted by the detergent dialysis method into various kinds of phosphatidylcholine vesicles and the receptor ability to bind 125I-labelled human serum transferrin (HST) was then evaluated. In our experimental conditions, the binding(More)
The protoporphyrin IX (PPIX)-sensitized hemolysis of erythrocytes depleted of cholesterol was investigated. From 20% to 30% of the total membrane cholesterol was removed from cells by incubation with old autologous plasma or by means of interaction with L-alpha-phosphatidylcholine dipalmitoyl (DPPC) liposomes. As expected, after this treatment, the cells(More)
Denaturation of human seminal transferrin (HSmT) compared with human serum transferrin (HSrT) was followed to check structural differences between these two proteins. Second derivative UV spectroscopy indicated that treatment with 6 M guanidine hydrochloride (Gnd.HCl) induced greater structural changes in HSrT than in HSmT and, in particular; (i) the(More)
A simple, non-invasive spectrophotometric assay to measure the concentration of some beta-lactam antibiotics in turbid solutions containing liposomes was carried out. Since zero-order spectra gave strong interference because of sample turbidity, derivative spectrophotometry was used to enhance the spectral details. Derivative spectra showed bands in the(More)
