Cholesterol transfer from mitochondrial membranes and cells to human and rat serum lipoprotein fractions.

open access: yesJournal of Lipid Research, 1989
We have investigated the transfer of [14C]cholesterol from labeled bovine heart mitochondria and Friend erythroleukemic cells to high density lipoprotein (HDL), low density lipoprotein (LDL), and very low density lipoprotein (VLDL) fractions from human ...

Mechanochemical enzymes and protein machines as hydrodynamic force dipoles: The active dimer model

open access: yes, 2020
Mechanochemically active enzymes change their shapes within every turnover cycle. Therefore, they induce circulating flows in the solvent around them and behave as oscillating hydrodynamic force dipoles.

Charge-induced phase separation in lipid membranes [PDF]

open access: yes, 2014
The phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of ...

Macrophage-enhanced formation of cholesteryl ester–core aldehydes during oxidation of low density lipoprotein

open access: yesJournal of Lipid Research, 1999
Oxidation of low density lipoproteins (LDL) results in changes to the lipoprotein particle that are potentially pro-atherogenic. To investigate mechanisms contributing to the formation of cholesteryl ester (CE)–core aldehydes (9-oxononanoyl- and 5 ...

TRIM Proteins in Colorectal Cancer: TRIM8 as a Promising Therapeutic Target in Chemo Resistance

open access: yesBiomedicines, 2021
Colorectal cancer (CRC) represents one of the most widespread forms of cancer in the population and, as all malignant tumors, often develops resistance to chemotherapies with consequent tumor growth and spreading leading to the patient’s premature death.

Global minimizers for axisymmetric multiphase membranes [PDF]

open access: yes, 2012
We consider a Canham-Helfrich-type variational problem defined over closed surfaces enclosing a fixed volume and having fixed surface area. The problem models the shape of multiphase biomembranes.

Systematic Study of Steroid Drugs’ Ability to Cross Biomembranes—The Possible Environmental Impact and Health Risks Associated with Exposure During Pregnancy

open access: yesMembranes
Thirty-seven steroid drugs of different types were investigated in silico for their environmental and pharmacokinetic properties (partition between soil and water, bioaccumulation in aquatic organisms, ability to be absorbed from the gastrointestinal ...

Membrane adhesion and domain formation

open access: yes, 2007
We review theoretical results for the adhesion-induced phase behavior of biomembranes. The focus is on models in which the membranes are represented as discretized elastic sheets with embedded adhesion molecules. We present several mechanism that lead to

Insights into Transfer of Supramolecular Doxorubicin/Congo Red Aggregates through Phospholipid Membranes

open access: yesMolecules
Doxorubicin (DOX) is a commonly used chemotherapeutic drug, from the anthracycline class, which is genotoxic to neoplastic cells via a DNA intercalation mechanism. It is effective and universal; however, it also causes numerous side effects.

Second order splitting of a class of fourth order PDEs with point constraints [PDF]

open access: yes, 2020
We formulate a well-posedness and approximation theory for a class of generalised saddle point problems with a specific form of constraints. In this way we develop an approach to a class of fourth order elliptic partial differential equations with point ...
