Effect of Structure and Composition of Reconstituted High Density Lipoproteins on Phosphatidylcholine Transfer by Human Plasma Phospholipid Transfer Protein
… used to study the effect of HDL substrates on phosphatidylcholine (PC) transfer by human plasma phospholipid transfer protein (PLTP) by changing the composition and size of rHDL. Sonicated egg-PC:cholesterol vesicles containing radiolabelled dipalmitoyl-PC ($\sp $C-DPPC) were used as donors and …

Biosynthetic Studies on Pactamycin
… 6-MSA would be an advanced precursor to the corresponding unit on pactamycin, but feeding experiments with 6-methyl (carboxy-$\sp $C) salicylic acid and methyl 6-methyl (carboxy-$\sp $C) salicylate failed to show significant incorporation into either pactamycin or its analogue pactamycate. In …

The Application of 'Magic Angle' Sample Spinning NMR to the Study of Liquid Crystals and Membranes
Proton and Carbon-13 "Magic Angle" Sample Spinning (MASS) NMR is shown to yield high-resolution spectra for a variety of fluid liquid crystalline phases. Relatively slow ca. 3-kHz MASS causes averaging of the broadening interactions in both $\sp $C and $\sp1$H spectra of liquid crystals. Due to the …

Synthesis, Structure, and Reactivity of High-Nuclearity Carbido Clusters of Rhenium
The cluster anion (Re$\sb7$C(CO)$\sb{21}\rbrack\sp{3-}$ reacts with late transition metal-based electrophiles to yield the mixed-metal clusters (Re$\sb7$C(CO)$\sb{21}$ML$\sb{\rm n}\rbrack\sp{2-}$ and with H$\sp+$ to yield the hydrido species (HRe$\sb7$C(CO)$\sb{21}\rbrack\sp{2-}$. These complexes …

Nuclear Magnetic Resonance Studies of Model and Biological Membranes
… proton MASS is shown to yield high resolution $\sp1$H NMR spectra from a smectic, nematic, and hexagonal-II phase liquid crystals. Isotropic chemical shifts, order parameters, and relaxation times can be determined from these spectra. Such experiments are possible because of the special form of …

Nuclear Magnetic Resonance Study of the Platinum - Rhodium Bimetallic Clusters
… of supported Pt-Rh bimetallic catalysts by $\sp{195}$Pt NMR and by $\sp $C NMR of adsorbed CO. The metal particles are 5A-50A in diameter. Study of the dependence of the $\sp $CO resonance position as a function of Pt/Rh ratio and particle size shows that Rh is segregated to the surface. Study …

Role of Lipoprotein Lipase in Lipid Metabolism: The Effects of Exercise and Diet
… to tissue uptake and plasma clearance of $\sp $C-labeled chylomicron TG (14C-CM-TG) were studied in rats fed the high fat diet. A single exercise session increased skeletal muscle and heart LPL activities with the highest activities and greatest responses in the heart and red muscle fiber …

New Strategies in Radical Chemistry and Their Application to the Construction of C(sp3)–C(sp3) Bonds in the Giese Reaction
Considering inert and strong C(sp³)–C(sp³) bonds constitute the skeleton of all organic molecules, the development of novel methods for their construction remains of significant interest for the synthetic community. In this thesis, a unique platform to access C(sp³)-centred radicals, and their …

Calcite cements in carbonates of the Sverdrup Basin, Canadian Arctic Archipelago.
… element study, application of Secondary Ion Mass Spectrometry (SIMS) enabled direct measurements of chemical composition in thin sections, constituting a precedent. The precisions obtained were 12, 6, 6 and 6% for Mg, Fe, Mn and Sr, respectively. Petrographic observations guided the micro-sampling …
