The influence of different factors on variations in the concentrations of total phospholipids and high-density-lipoprotein (HDL) phospholipids in plasma was studied in a presumably healthy population of 2000 subjects, four to 70 years old. Age is the major factor associated with variation of total phospholipids. In females, this is due in part to age-related changes in hormonal status. The use ...

Serum phospholipid levels were determined in 1,067 healthy persons aged 2 to 77 years. Phospholipid levels increased with age but in a different way for each of the sexes. The age-sex changes of serum phospholipids were similar to those observed for serum cholesterol. Correlation coefficients in members of 156 families indicated that the genetic factor is of importance in determining the serum ...

We present here an easy method to modify the surface chemistry of polymeric microcapsules of perfluorooctyl bromide used as ultrasound contrast agents (UCAs). Capsules were obtained by a solvent emulsification-evaporation process with phospholipids incorporated in the organic phase before emulsification. Several phospholipids were reviewed: fluorescent, pegylated and biotinylated phospholipids....

Hydrophilic and negatively charged natural cartilage surface is covered by phospholipids bilayers. These have been demonstrated to exert highly desirable characteristics on the articular such as efficient lubrication, load processing, semipermeability for nutrient transport. We examined a bovine (BC) using atomic force microscope. The study was performed samples with healthy surfaces completely...
