Minke whales (Balaenoptera acutorostrata) are the smallest member of balaenopterid whales and little is known of their kinematics during feeding maneuvers. These whales have narrow and elongated flippers that are small relative to body size compared…
Bile acids activate a nuclear receptor, farnesoid X receptor (FXR), that induces bile salt export pump (BSEP) but inhibits cholesterol 7alpha-hydroxylase (CYP7A1) gene transcription in the liver. Guggulsterone, a plant sterol that lowers serum…
The omega-hydroxylation of fatty acids by certain cytochrome P450 enzymes shows a degree of chain-length and regiospecificity which is remarkable in view of the conformational flexibility of these substrates, the strong similarity in properties among…
Mitochondria-derived oxygen-free radical(s) are important mediators of oxidative cellular injury. It is widely hypothesized that excess NO enhances O(2)(center dot-) generated by mitochondria under certain pathological conditions. In the…
The effect of 1-palmitoyl lysophosphatidylcholine (PLPC) on the phase behaviour of 1,2-dipalmitoyl phosphatidylethanolamine (DPPE) in excess water (34 wt%) has been examined by differential scanning calorimetry, scanning dilatometry and isothermal…
The interaction of chloroform with bilayers of dimyristoylphosphatidylcholine (DMPC) has been studied by deuterium and phosphorus-31 nuclear magnetic resonance (NMR). Orientational order has been measured as a function of temperature at many sites in…
Oxygen is known to partition with an increasing concentration gradient toward the hydrophobic membrane interior. At partial pressures (P-O2) of 100 Atm or more, this concentration gradient is sufficient to induce paramagnetic effects that depend…
Ethanol-inducible cytochrome P450 2E1 (CYP2E1) has been shown to be involved in the metabolism of both ethanol and acetaldehyde, Acetaldehyde, produced from ethanol metabolism, is highly reactive and can form various protein adducts, In this study,…
Neurons in the chicken nucleus laminaris (NL), the third-order auditory neurons that detect the interaural time differences that enable animals to localize sounds in the horizontal plane, receive glutamatergic excitation from the cochlear nucleus…
An anomalous phase transition with a marked rise in specific heat, the isobaric thermal expansion coefficient, and the compressibility coefficient at 62.5 degrees C for an equimolar mixture of 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE)…
The structure-function relationships of the 43-amino-acid membrane-binding domain of cytochrome b(5) have been examined in two mutant forms of the protein. In one mutant, two tryptophans in the membrane-binding domain, at positions 108 and 112, were…
Endothelial cell polarization and directional migration is required for angiogenesis. Polarization and motility requires not only local cytoskeletal remodeling but also the motion of intracellular organelles such as the nucleus. However, the…
