BACKGROUND The fatty acid content and saturation degree of the diet can modulate HDL composition and cholesterol efflux. OBJECTIVE We studied the modifications in plasma lipoprotein particles and serum capacity to stimulate cholesterol efflux induced by different fatty acids. DESIGN Seventeen women and 24 men followed in the same sequence 4 diets(More)
BACKGROUND In Spain the mortality rate due to cardiovascular disease (CVD) is relatively low compared to that of other developed countries. Until now few epidemiological studies have been performed among the global Spanish population to evaluate a relation between CVD risk factors and the lipid profile that could justify our privileged situation. For, this(More)
Increased plasma lipoprotein(a)-Lp(a)-levels are linked to a high risk of cardiovascular disease unrelated to other lipoproteins. It seems that Lp(a) values in childhood remain unaltered up to adulthood. In a randomly chosen population of 1970 children, aged from 4 to 18 years and living in a Spanish community, the following serum parameters were studied:(More)
BACKGROUND AND OBJECTIVE The aim of this study was to describe the lipid profile, the levels of serum total cholesterol (TC), LDL cholesterol (C-LDL), HDL cholesterol (C-HDL) and triglyceride (TG), to compare these levels between geographical areas and to estimate the prevalence of dyslipidemia in elderly residents (65 years and older) from urban and rural(More)
The clinical, hematological, and biochemical characteristics of a new family with heterozygous hemoglobin (Hb) Louisville are described. The family showed a decrease in both oxygen affinity and cooperativity with the normal Bohr effect. This family has the greatest number of affected members reported to date. Among the descendants, two first cousins (III-10(More)
Although the complex and multifactorial process of tumour growth has been extensively studied for decades, our understanding of the fundamental relationship between tumour growth dynamics and genetic expression profile remains incomplete. Recent studies of tumour dynamics indicate that gene expression in solid tumours would depend on the distance from the(More)
There is evidence that polymorphonuclear neutrophils (PMNs) can exert severe antineoplastic effects. Cross-talk between tumour cells and endothelial cells (ECs) is necessary for the accumulation of PMN around a tumour. This work reports the ability of two PMN-sensitive, human, permanent cell lines-colorectal adenocarcinoma (HT-29) and pharyngeal(More)
BACKGROUND Plasma glucose, insulin and blood pressure are wellknown cardiovascular risk factors, which may be influence by dietary factors. The aim of the study was to investigate whether changes in dietary fatty acids could modify plasma concentration of glucose, insulin and mean blood pressure (MBP). SUBJECTS AND METHODS Forty two subjects (18 women and(More)
BACKGROUND AND OBJECTIVE alpha-thalassemia is very common on all thalassemic geographical regions. The present work aimed at analyzing the relationship between the degree of microcytosis and hematological parameters and the type of alpha-thalassemic mutation. DESIGN AND METHODS Five hundred and thirty-six subjects with 4 kinds of alpha-thalassemia were(More)
Chronic rejection - also called chronic renal allograft dysfunction (CRAD) - is the main cause of long-term loss of the transplanted kidney, but its pathogenesis is not well known. The aim of this study was to know if lipoproteins, fibrinogen, plasminogen activator inhibitor-1 (PAI-1) and platelet aggregation show more abnormalities in renal transplant(More)
