HDL-cholesterol and breast cancer : a joint study in northern Italy and southern France

The goal of the present study is to evaluate HDL-cholesterol (HDL-C) as a marker of breast cancer (BC) risk. It is based on several epidemiological and biological studies and is justified by the rising incidence of breast cancer throughout the world. A hospital-based study on host-related risk factors and breast cancer, conducted with similar methods in northern Italy and southern France, provided the biological data, the information on the established BC risk factors and on nutrition for 307 cases and 329 controls. This data set allowed for a thorough analysis of the relationship of HDL-C with established risk factors for BC and also of its association with BC at the time of diagnosis. Most of our findings on HDL-C determinants in the control sample are comparable to previous studies. The BC risk factors associated with reproductive life correlate with HDL-C levels: the protective factors are associated with a lower level of HDL-C and inversely. The same is true for nutritional factors such as alcohol. For these determinants, the trend is similar for cases and controls, and HDL-C level appears to be related to oestrogen metabolism. Thus it may be considered as a marker of BC risk. Our results indicate that high HDL-C levels should be especially checked in women aged > or = 60 years, or in premenopausal women presenting a low BMI, or in postmenopausal women with an early menopause

Liposoluble vitamins and lipid parameters in breast cancer. A joint study in northern Italy and southern France

The relationship between breast cancer, liposoluble vitamins, cholesterol and triglycerides was investigated by means of a hospital-based case-control study conducted at Milan (Italy) and Montpellier (France). These parameters were measured in blood samples taken from 319 cases and 344 controls. The interview included an evaluation of dietary intake of liposoluble vitamins. No difference emerged in liposoluble vitamin consumption, whereas a statistically significantly higher serum level of cholesterol and plasma level of vitamin E existed in cases compared to controls. The difference in plasma vitamin E was confirmed after adjustment for total cholesterol and triglycerides. In contrast, vitamin A variations appear to follow triglyceride trends. A multivariate analysis of the vitamin E plasma level was performed after classification of cases and controls according to quintile distribution of controls. All known risk factors plus age, serum total cholesterol and triglycerides were used as covariates. The odds ratio value for the highest quintile of plasma vitamin E is: 4.2 (1.9-9.0)

ASYL: a logic and architecture design automation system

This paper is focused on the ASYL system with a special emphasis on the four most original aspects which are the 2-level minimization, the multi-level synthesis on PALs, the multi-level synthesis on compiled cells, and the state assignment of controllers. The ASYL system which is dedicated to synthesis is coupled with the CADOC system. CADOC which has been developed in the framework of an ESPRIT Project, is dedicated to functional simulation and is used as a high-level input-language and as a simulator. Results for the different topics are presented on classical international benchmarks
