HEAVY MAMAS Pregnant women who are overweight before pregnancy face a threefold increased risk of having a stillborn baby. It's thought that Mom's high lipid levels may somehow impair the placenta's ability to function...
...existence or demonstration of the existence of the channel does not tell us how it works, that is, how is it opened and closed," Rapoport said. "How do proteins move across in one direction and how does it open laterally to let membrane proteins out into the lipid bilayer...
...water's flow, Biebuyck says, is analogous to the movement of molecules across the lipid membranes of human cells. Such membranes are sprinkled with proteins which are hydrophobic on one end and hydrophilic on the other, like the configuration of the silicon surface...
CEREDASE, A BREAKTHROUGH TREATMENT for the crippling and sometimes fatal , genetic disorder called Gaucher's disease, is changing lives, even saving them -- but not always making them better.

Just how HDL plays its apparently vital role in ridding the body of excess cholesterol is not entirely clear. The substance is, after all, only one element in an alphabet soup of particles that make up the so-called lipid transport system, which moves cholesterol through the bloodstream. Though individual cells can make their own cholesterol, much of their supply comes from the bloodstream, arriving from the liver aboard macromolecular ferryboats, known as very-low-density lipoproteins, or VLDLs. These carrier particles are loaded in the liver with cholesterol and dietary fats known as triglycerides, which are used by cells...
