Differential insertion of arginine in saturated and unsaturated lipid vesicles.
Biochim Biophys Acta Biomembr
December 2024
Article Synopsis
- This study investigates how L-Arginine (L-Arg) affects lipid membranes using various techniques like fluorescence spectroscopy and dynamic light scattering.
- L-Arg reduces the polarizability of saturated lipids, leading to an increase in vesicle size, while in unsaturated lipids, it increases polarizability without significantly changing size.
- The interaction of L-Arg differs based on whether the lipids are saturated or unsaturated, and cholesterol appears to dampen these effects.
Interaction of L-phenylalanine with carbonyl groups in mixed lipid membranes.
Biochim Biophys Acta Biomembr
June 2024
The interaction of L-Phe with the membrane components, i.e., lipids and proteins, has been discussed in the current literature due to the interest to understand the effect of single amino acids in relation to the formation of amyloid aggregates.

Area-based breast density measurements may not provide an accurate representation of the tissue distribution, therefore volumetric breast density (VBD) measurements are preferred. Dual-energy mammography enables volumetric measurements without additional assumptions about breast shape.

Procedures: Two reconstruction algorithms were evaluated: a filtered backprojection (FBP) algorithm and a simultaneous iterative reconstruction technique (SIRT) algorithm. A 3D bilateral filter (BF) was used for noise removal.
