The modulation of calcium channel density and oxidative capacity in skeletal muscle after different training protocols were studied in 3-year-old Atlantic salmon smolts. The effect of endurance exercise on dihydropyridine (DHP) and ryanodine (Ry) receptor densities as well as on muscle metabolism were determined by immunoblot and histochemical analysis from swimming muscles of fish subjected to...

In 2004, Muzereau et al. showed how to use a reduction algorithm of the discrete logarithm problem to DiffieHellman problem in order to estimate lower bound on Diffie-Hellman problem on elliptic curves. They presented their estimates for various elliptic curves that are used in practical applications. In this paper, we show that a much tighter lower bound for Diffie-Hellman problem on those cur...

The synthesis of the cyclooctatetraene dianion (COT(2-)) fused at the [e]-position of trans-10b,10c-dimethyl-10b,10c-dihydropyrene (DHP) is described, and by comparison of (1)H NMR properties and NICSAv to the analogous benzene fused DHP, the relative aromaticity of the dianion is found to be at least as great as that of benzene, and substantially larger than that of the cyclopentadienide anion.

A 76-year-old female underwent ascending aorta and partial arch replacement. She developed septic shock on postoperative day 6. She was administered dopamine, 10 microg x kg(-1) x min(-1); dobutamine, 5 microg x kg(-1) x min(-1); and norepinephrine, 0.3 microg x kg(-1) x min(-1). However, the blood pressure was 74/40 mmHg. Direct hemoperfusion using polymyxin B-immobilized fiber (PMX-DHP) was s...

Effects of allixin, a phytoalexin of garlic, and its analogues were studied on the survival and morphology of primary cultured neurons from fetal rat brain. Addition of allixin (1-100 ng/ml) to medium significantly promoted the survival of neurons derived from various regions of brain and increased the number of branching points per axon in hippocampal neurons. Allixin, however, was cytotoxic a...

In order to better understand bacterial depolymerization of lignin, a new analytical approach was proposed using Pseudomonas putida KT2440 as delignifying bacterium and Escherichia coli non-delignifying control. Two different types lignins, technical Kraft lignin synthetic dehydrogenopolymer (DHP), were submitted bioconversion kinetic study over 7 days. The concomitant analysis the supernatant ...

Studies on the amphibian neuromuscular junction have indicated that N-type calcium channels are the sole mediators of stimulus-evoked neurotransmitter release. We show, via both presynaptic and postsynaptic voltage-clamp measurements, that dihydropyridine (DHP)-sensitive calcium channels also contribute to stimulus-evoked release at developing Xenopus neuromuscular junctions. Whereas inhibition...

Results The two groups did not differ significantly in age, APACHE II score, SOFA score, infection focus, and bacterial species. The 28-day mortality was 32% in the PMXDHP group and 40% in the non-PMX-DHP group, but this difference was not significant. The ⊿CAI (the change in Cathecholamine Index 24 hours after PMX-DHP administration) and the infusion volume 24 hours after PMX-DHP administratio...

The recombination dynamics of NO with dehaloperoxidase (DHP) from Amphitrite ornata following photolysis were measured by femtosecond time-resolved absorption spectroscopy. Singular value decomposition (SVD) analysis reveals two important basis spectra. The first SVD basis spectrum reports on the population of photolyzed NO molecules and has the appearance of the equilibrium difference spectrum...

We have explored the effect of substrate binding on the heme iron conformation in the enzyme dehaloperoxidase (DHP) that was first isolated from the terebellid polychaete Amphitrite ornata and is now expressed in Escherichia coli.1-3 DHP is a dimeric hemoglobin4 that also has significant peroxidase activity under physiological conditions.5 Since hemoglobins and peroxidases require ferrous and f...
