OBJECTIVE Levels of lipids and (apo)lipoproteins are known to increase after menopause, but it is unknown whether the genetic and environmental variability alters or whether lipids and (apo)lipoproteins are influenced by different genes before and after menopause. METHODS AND RESULTS We studied 453 monozygotic and 1280 dizygotic pairs of female white twins recruited from the St. Thomas' UK Ad...

Measures of socioeconomic status have been shown to be related positively to levels of high density lipoprotein (HDL) cholesterol in white men and women and negatively in African American men. However, there is little information regarding the association between educational attainment and HDL fractions or apolipoproteins. The authors examined these associations in 9,407 white and 2,664 African...

Cardiovascular diseases with an incidence of approximately 50% are the main causes of death in most advanced countries and an increasing trend in the developing world as well. The World Health Organization estimates that 12 million people per year worldwide die from cardiovascular diseases. Cardiovascular diseases are becoming an increasing problem worldwide and hypercholesterolemia has been co...

In general, encoding for LDPC codes can be difficult to realize efficiently. This paper presents techniques and architectures for LDPC encoding that are efficient and practical for a particular class of codes. These codes are the irregular partitioned permutation LDPC codes recently introduced by the author at ICC’03, [4]. Since these codes are quasi-cyclic, it is known that a simpler encoding ...

BACKGROUND Recently, the American Academy of Pediatrics updated guidance on lipid screening in childhood. Our objective was to examine recent distributions in concentrations of total cholesterol and low-density lipoprotein cholesterol among US children and adolescents and to estimate the prevalence of adolescents who are potentially eligible for pharmacological treatment for elevated concentrat...
