The aim of this study was the characterization of mutations of the LDL receptor gene in 39 Italian patients with homozygous familial hypercholesterolemia, who were examined during the period 1994 to 1996. The age of the patients ranged from 1 to 64 years; one third of them were older than 30. Plasma LDL cholesterol level ranged from 10.8 to 25.1 mmol/L. The(More)
The clinical expression of heterozygous familial hypercholesterolemia (FH) is highly variable even in patients carrying the same LDL receptor (LDL-R) gene mutation. This variability might be due to environmental factors as well as to modifying genes affecting lipoprotein metabolism. We investigated Apo E (2, 3, 4), MTP (-493G/T), Apo B (-516C/T), Apo A-V(More)
The events leading to the onset of the experimental bleomycin-induced pulmonary fibrosis are so far unknown, though recent observations emphasize the crucial role played by lung phospholipids and by alveolar macrophages. In an attempt to verify this point, a series of studies were undertaken by treating rats (CD-COBS) with intratracheal instillation of a(More)
We have used four restriction fragment length polymorphisms (RFLPs) of the human low density lipoprotein receptor (LDL-R) gene, detected by the restriction enzymes Ava II, Pvu II, and ApaLI (5' and 3'), to study the effect of variation at this gene locus in determining plasma cholesterol and LDL cholesterol levels. Two hundred eighty-nine normolipidemic(More)
In the LDL-receptor gene, a large rearrangement causing hypercholesterolemia was detected in three apparently unrelated families living in northern Italy. In all probands, binding, internalization, and degradation of 125I-LDL measured in skin fibroblasts were found to be 40%-50% of control values, indicative of heterozygous familial hypercholesterolemia(More)
In this study, we report four new partial deletions of the LDL-receptor (LDL-R) gene discovered during a survey of 326 Italian patients with familial hypercholesterolemia (FH). All deletions were found in FH heterozygotes whose LDL-R activity in skin fibroblasts ranged from 52% to 43% of the values found in control cells. The size and boundaries of the(More)
Benserazide induces an increase of serum prolactin in man, possibly as the result of an impairment of the dopamine effect on the pituitary and/or on the outer median eminence caused by the inhibition on L-dopa decarboxylase. On the other hand, liposomes obtained from bovine brain cortex phospholipids reduced serum prolactin possibly through an effect of(More)
BACKGROUND AND PURPOSE Although epidemiologic investigations are trying to clarify the role of plasma lipid concentrations (primarily cholesterol and its subfractions) as risk factors for both ischemic and hemorrhagic stroke, little information is available regarding the effect of sustained hypercholesterolemia on cerebral perfusion.
