Phospholipid signaling

Cell, 1995
Ten years ago, describing what is new in phospholipid signaling in ten pages of Cell would have been easy; it would have been essentially a summary of the phospho-inositidase C (PIC) story: phosphatidylinositol(4,5)bisphos-phate (Ptdlns(4,5)P2) hydrolysis to inositiol(1,4,5)trisphos-phate (Ins(1",4,5)P3), with the synergistic action of Ca 2÷(mobilized ...

Influence of Phospholipid and Protein Constituents on Tribological Properties of Artificial Hydrogel Cartilage Material

Journal of Biomechanical Science and Engineering, 2013
In this study, the influence of phospholipid and protein constituents on friction and wear behavior of artificial hydrogel cartilage was investigated. A sliding pair of an ellipsoidal specimen of poly (vinyl alcohol) (PVA) hydrogel and a flat specimen of

The cholesterol-raising diterpenes from coffee beans increase serum lipid transfer protein activity levels in humans [PDF]

, 1997
Cafestol and kahweol–diterpenes present in unfiltered coffee— strongly raise serum VLDL and LDL cholesterol and slightly reduce HDL cholesterol in humans. The mechanism of action is unknown.

Microbial community dynamics during composting of sewage sludge and straw studied through phospholipid and neutral lipid analysis [PDF]

, 2008
The composting process involves a succession of different communities of microorganisms that decompose the initial material, transforming it into a stable final product. In thiswork, the levels of phospholipid fatty acid (PLFA), neutral lipid fatty acid (

Role of individual amino acids of apolipoprotein A-I in the activation of lecithin:cholesterol acyltransferase and in HDL rearrangements

Journal of Lipid Research, 2001
The central region of apolipoprotein A-I (apoA-I), spanning residues 143–165, has been implicated in lecithin:cholesterol acyltransferase (LCAT) activation and also in high density lipoprotein (HDL) structural rearrangements.

Nanomechanical properties of phospholipid microbubbles [PDF]

, 2012
This study uses atomic force microscopy (AFM) force-deformation (F-Delta) curves to investigate for the first time the Young's modulus of a phospholipid microbubble (MB) ultrasound contrast agent. The stiffness of the MBs was calculated from the gradient

Imaging optical thicknesses and separation distances of phospholipid vesicles at solid surfaces [PDF]

, 1992
We present the application of reflection interference contrast microscopy (RICM) (1) to map the optical density of supported bilayers and vesicles and (2) to image the contact profile of phospholipid vesicles at surfaces.

Interaction of Small Ionic Species With Phospholipid Membranes: The Role of Metal Coordination

Frontiers in Materials, 2019
In studies of the transfer, distribution and biochemical activity of metal ions it is typically assumed that the phospholipid bilayer acts as an inert barrier.

Lipidomic analysis of plasma from healthy men and women shows phospholipid class and molecular species differences between sexes [PDF]

, 2020
The phospholipid composition of lipoproteins is determined by the specificity of hepatic phospholipid biosynthesis. Plasma phospholipid 20:4n-6 and 22:6n-3 concentrations are higher in women than in men.

Microstructural characterization of phospholipid membranes and study of their interaction with peptides and proteins. [PDF]

, 2011
In the present thesis, a wide structural and functional study on biomembranes is presented. The research has been focused on the micro- and mesostructure of phospholipid bilayers and on their interactions with different peptides which are involved in ...
