Ligand Diffusion Pathways and Mechanisms for Regulating Oxygen Affinity in Two Model Invertebrate Globins: The E7 Gate and Apolar Tunnel
… tunnel between the E- and H-helices. This apolar channel has been suggested to represent an alternative to the HisE7 gate pathway. To determine the roles of the E7 gate and alternative pathways, we have systematically examined the effects of mutations at the E7 position in ScHbI and CerHb …

Mitigating fouling of heat exchangers with fluoropolymer coatings
… of the deposit. At the interface with apolar surfaces raw milk fouling layers are high in protein, whereas a strongly attached mineral-rich layer is present at the interface with steel. Whey protein deposits generated on apolar surfaces are more spongy and have a lower thermal …

Part I: Self-Assembling Dendrimers Using the Dda-Aad Hydrogen Bonding Motif. Part II: Supramolecular Discotic Liquid Crystals Through Hydrogen Bond Mediated Self-Assembly
… formation of a hydrogen bonded cyclic hexamer in apolar solvents. The studies by differential scanning calorimetry (DSC), polarized light microscopy (PLM) and X-ray diffraction (XRD) indicate that the hexameric disks can stack in bulk to form thermotropic columnar mesophases. The mesophases exist …

Interfacial Phenomena and Surface Forces of Hydrophobic Solids
… and aqueous liquids, the low solubility of apolar solutes in aqueous solvents, and self-assembly in biological processes, such as vesicle formation and protein folding. Although it is known that a strong attraction between apolar molecules exists at the molecular level, it is not clear how …

Ionenkanäle während der Nephrogenese
… Sammelrohrepithel und Nephron ubiquitär apolar exprimiert. Im Gegensatz hierzu war Kir6.1 im adulten Nephron ausschließlich im Proximalen Tubulus nachweisbar (apikal > basolateral). Die spezifische Aktivierung von KNDP-(KATP)-Kir6.1/SUR2-Kanälen in Nephronkulturen und HEK293-Zellen …

An examination of the relationship between epithelial to mesenchymal transition and cancer stem cells in solid tumors
… phenotype (epithelial) to a motile, plastic, and apolar phenotype (mesenchymal). EMT is correlated with metastasis; EMT is usually measured by QRT-PCR or immunohistochemistry. Cancer stem cells are thought to be responsible for metastasis and recurrence. They have been found in almost all solid …

Self-assembly of conformal polymer electrolyte film for lithium ion microbatteries
I apply the theory of polar and apolar intermolecular interactions to predict the behavior of combinations of common battery materials, specifically the cathode substrate lithium cobalt oxide (LCO) and the polymer separator poly(ethylene oxide). These predictions were first tested qualitatively …

Development of chemosensors for endocrine disrupting chemicals (EDCs): synthesis and evaluation of solid-phase bound receptors
… polar compounds stay in the water sample while apolar compounds are retained on the solid phase. As a consequence the selectivity of the SPE is poor. A solid-phase material which could selectively bind the different EDCs would thus greatly simplify the analysis. This PhD will focus on the …

Molecular recognition from atomic interactions: insights into drug discovery
… profiles are defined in terms of polar and apolar contacts, with the aim of migrating natural patterns into the design of new therapeutics.

The effects of Hydroxypropyl-β-Cyclodextrin on the American Flagfish (Jordanella floridae) over one complete life-cycle
… as well as improve the aqueous solubility of apolar guest compounds. As such, the use of HPβCD in the pharmaceutical and personal care industry has dramatically increased. With increasing potential for entering the environment through wastewater treatment plant (WWTP) effluent, HPβCD poses an …

Bijels For Continuous Reactive Separations
… two immiscible phases can host both polar and apolar species and at the same time allowing separation of molecules of different polarity by simple phase partitioning. Two forms of biphasic reactive separation systems have been studied: emulsion-based and membrane-based systems. However, the …

Binding affinity of a small molecule to an amorphous polymer in a solvent
… site (taken into account the effects of polar/apolar atom interactions between an aspirin and a polymer). These results suggest the possibility of using binding affinity, especially the free energy of binding to the best site and the number of nucleating molecule, to help guide the selection of …

Novel Intermediate Filaments in the Nuclear Envelope: Molecular Cloning and Analysis of Lamins A and C
… hydrophobic or nonpolar. This results in an apolar stripe down one side of the α-helix. Lamins A and C may therefore assemble into coiled coil homodimers by interactions of their α-helical domain. Coil 1B of the lamins is approximately twice the size of Coil 1B of intermediate filament …

Propriedades eletrônicas, estruturais e espectroscópicas de diazocetonas através de cálculos quânticos e estudos in silico das ligações realizadas pela molécula de amurensinina no sítio de ligação do receptor específico de N-metil-D-Aspartato (NMDA)
… e vários resíduos de aminoácidos de caráter apolar. Por meio deste estudo foi constatado que a amurensinina interage com o receptor NMDA em seu domínio estrutural ATD. Possivelmente a amurensinina possui uma ação antagonista no receptor por se ligar em uma região semelhante à do ifenprodil; …

Thermal cis-trans isomerization of azobenzene studied by path sampling and QM/MM stochastic dynamics
… from linear inversion to rotation in going from apolar to polar solvent, predicted by the TST approach, could be verified for the push-pull derivative. At the same time, the mere presence of explicit solvation is seen to broaden the distribution of isomerization pathways, an effect TST cannot …

Sustainable Mining - Solving the Problem of Chalcopyrite Treatment/Processing - Leaching, Solvent Extraction & Flotation
… with surface energies γCuFeS2^(LW) = 41.4 mJ/m² (apolar), γCuFeS2^(AB) = 2.9 mJ/m² (polar). The high value of the surface energy indicates pure chalcopyrite surface is slightly hydrophobic.
