Local Interactions in Aqueous Ethanol Solution Revealed by the C=O Stretching Probe

Molecules
Accurately identifying local interactions such as hydrophilicity and hydrophobicity is of critical importance in regulating the functions of amphiphilic biomolecules, but in situ identification methods for such interactions are still lacking.

Separation of highly hydrophilic nicotinamide metabolites using a COSMOSIL PBr column

MethodsX, 2023
Highly hydrophilic compounds such as nicotinamide metabolites are very difficult to separate via high-performance liquid chromatography (HPLC) using octadecyl (C18) columns. In general, for the separation of hydrophilic compounds, hydrophilic interaction

Crystal engineering with short-chained amphiphiles: decasodium octa-n-butanesulfonate di-μ-chlorido-bis[dichloridopalladate(II)] tetrahydrate, a layered inorganic–organic hybrid material

Acta Crystallographica Section E: Crystallographic Communications, 2019
In the course of crystal-engineering experiments, crystals of the hydrated title salt, Na10[Pd2Cl6](C4H9SO3)8·4H2O, were obtained from a water/2-propanol solution of sodium n-butanesulfonate and sodium tetrachloridopalladate(II). In the crystal, sodium n-

Crossovers in supercooled solvation water: Effects of hydrophilic and hydrophobic interactions

EPL (Europhysics Letters), 2015
We use systematic 8 ns ab initio molecular dynamics (AIMD) to study the structure and dynamics of water in bulk, and close to both hydrophobic and hydrophilic (carbonyl) groups of tetramethylurea (TMU). We observe crossovers in the dynamical behavior around the hydrophobic group at $T_X = 256 \pm 4$K and another one at $265 \pm 5$K related to the ...

Interplay of Hydrophobic and Hydrophilic Interactions in a Mixed Polyoxometalate/Organic Langmuir Monolayer [PDF]

Chemistry Letters, 2012
Abstract The surfactant molecules at a Langmuir monolayer interact with each other via both hydrophobic and hydrophilic interactions. The interplay between those molecular interactions leads to the molecular arrangement of the monolayer.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

Selection strategy for encapsulation of hydrophilic and hydrophobic ingredients with food-grade materials: A systematic review and analysis

Food Chemistry: X
Various lipid and biopolymer-based nanocarriers have been developed to encapsulate food ingredients. The selection of nanocarrier type, preparation techniques, and loading methods should consider the compatibility of nutrient properties, nanocarrier ...
