Using x-ray scattering measurements we have quantitatively determined the effect of poloxamer 188 (P188), a polymer known to seal damaged membranes, on the structure of lipid monolayers. P188 selectively inserts into low lipid-density regions of the membrane and "corrals" lipid molecules to pack tightly, leading to unexpected Bragg peaks at low nominal lipid density and inducing lipid/poloxamer...
Rhenium-catalyzed stereoselective transposition of allylic alcohols is reported.
Facile synthesis of multinuclear complexes based on a tetra(4-pyridyl)amidinate dirhodium(II) dimer.
Four rhenium(I) chromophores attached to a dirhodium(n) core form a new hexametallic light-harvesting assembly as characterised by X-ray crystallography, UV-vis spectroscopy and electrochemistry.
The principles of infrared emission spectroscopy are briefly reviewed with emphasis on the aspects of its application to the study of chemisorbed species. The ma in problems of sample preparation, selection of measurement conditions and the most suitable methods of data treatment are discussed. IR emittance spectra of two typical support materials for supported metal catalysts, aJumina and sili...
alumina-supported cs3[re(c2o4)3] precursor has been synthesized for preparation of re-cs/g-al2o3 catalyst. cs3[re(c2o4)3] has been prepared from the reaction of recl3 with h2c2o4.2h2o and cscl in water. the complex has been characterized by elemental analysis and various spectroscopy techniques such as ft-ir, uv-vis and 13c-nmr. the complex was supported on γ-al2o3 by column chromatography. ...
Rhenium complexes functionalised with thioester-terminated alkyl chains can be attached to gold nanoparticles to yield water-soluble, visibly luminescent Re-GNP hybrid conjugates.
A new photo-active rhenium(I) bipyridyl based rotaxane has been synthesised which by virtue of the unique interlocked structural cavity selectively senses hydrogensulfate using luminescence spectroscopy.
The replacement of one pyrazole ligand by 2-aminopyridine in previously known rhenium tricarbonyl pyrazole complexes leads to more selective anion hosts.
Obesity is a critical health concern and although genetic factors may predispose an individual to become obese, changes in diet and lifestyle over the last few decades are likely to be significant contributors. Even so, it has been suggested that the causes of the current obesity crisis are not simply explained by changes in eating and exercise habits. Evidence suggests that the gut microbiota ...
Inhibition of the bile salt export pump (BSEP) can cause intracellular accumulation of bile acids and is a risk factor for drug-induced liver injury in humans. Antiretroviral protease inhibitors lopinavir (LPV) and ritonavir (RTV) are reported BSEP inhibitors. However, the consequences of LPV and RTV, alone and combined (LPV/r), on hepatocyte viability, bile acid transport, and endogenous bile ...
