Ou et al 1 report that an apolipoprotein A-I (apoA-I) mimetic peptide, D-4F, reduced wall thickness and improved vasoreactivity in the fascialis artery (internal diameter 180 to 240 m) in low-density lipoprotein (LDL) receptor–null mice on a Western diet. If the mice also lacked apoA-I, D-4F improved vasoreactivity but it did not reduce wall thickness. The authors concluded that apoA-I or some ...

and Applied Analysis 3 is called a quadratic functional equation. In particular, every solution of the quadratic functional equation is said to be a quadratic mapping. A generalized Hyers-Ulam stability problem for the quadratic functional equation was proved by Skof 7 for mappings f : X → Y , where X is a normed space and Y is a Banach space. Cholewa 8 noticed that the theorem of Skof is still...

Ewes bearing more than 1 fetus are more susceptible to pregnancy toxemia than those with a single fetus. Crossbreeding programs in Israel increased the occurrences of ewes bearing more than 2 fetuses; therefore, the aim was to assess the exacerbation in the metabolic status of ewes pregnant with several fetuses. Fifty ewes, genetically developed to achieve multiple-fetus pregnancies, were monit...

The production of 20-hydroxyeicosatetraenoic acid (20-HETE) in the kidney is thought to be involved in the control of renal vascular tone and tubular sodium and chloride reabsorption. 20-HETE production in the kidney has been extensively studied in rats and humans and occurs primarily via the actions of P-450 enzymes of the CYP4A and -4F families. Recent advancements in molecular genetics of th...

Luminescent properties of Sr 9 Lu(PO 4 ) 7 crystalline powders doped with Pr 3+ ions upon excitation in the ultraviolet region spectrum are considered. temperature range 5-320 K, considered.. In photoluminescence spectra, an intense glow corresponding to radiative interconfigurational 5d->4f-electronic transitions, weak narrow lines intra-configuration 4f->4f-transitions, and also...

The two new 3d/4f polyphosphide complexes [(Cp*Fe)(2)P(10){Sm(η(5)-C(5)Me(4)R)(2)}(2)] (Cp* = η(5)-C(5)Me(5); R = Me, nPr) were prepared by reductive dimerization of [Cp*Fe(η(5)-P(5))] with samarocenes. They are the first P(10) bridging 3d/4f metal complexes and the first examples of reductive coupling of polyphosphide complexes by divalent lanthanides.

A series of custom-designed, high yield, isoskeletal tetranuclear Zn/4f coordination clusters showing high efficiency as catalysts with low catalytic loadings in Friedel-Crafts alkylation are described for the first time. The possibility of altering the 4f centers in these catalysts without altering the core topology allows us to further confirm their stability via EPR and NMR, as well to gain ...

The 4f electrons of lanthanides, because of their strong localization in the region around the nucleus, are traditionally included in a pseudopotential core. This approximation is scrutinized by optimizing the structures and calculating the interaction energies of Gd(3+)(H(2)O) and Gd(3+)(NH(3)) microsolvation complexes within plane wave Perdew-Burke-Ernzerhof calculations using ultrasoft pseud...

A new series of thiadiazole-enaminones 4 were synthesized via reactions of 5-acetyl-1,3,4-thiadiazoles 3 with dimethylformamide-dimethylacetal (DMF-DMA). The simple phenyl substituted thiadiazole-enaminone 4f was used as a synthetic precursor for the preparation of a wide variety of new heterocyclic compounds, including the 5-substituted-1,3,4-thiadiazole derivatives 5, 6, 11, 12 and 13, which ...
