Methylarachidonylfluorophosphonate (MAFP) and related analogs have been shown to inhibit fatty acid amidohydrolase activity (FAAH), the enzyme responsible for hydrolysis of the endogenous cannabinoid ligand anandamide. To fully characterize this class of compounds, methylfluorophosphonate compounds with saturated alkyl chains ranging from C8 to C20 along with C20 unsaturated derivatives were sy...

the topological index of a graph g is a numeric quantity related to g which is invariant underautomorphisms of g. the vertex pi polynomial is defined as piv (g)  euv nu (e)  nv (e).then omega polynomial (g,x) for counting qoc strips in g is defined as (g,x) =cm(g,c)xc with m(g,c) being the number of strips of length c. in this paper, a new infiniteclass of fullerenes is constructed. the ...

The starvation effects on the fatty acids composition of the digestive gland of the scallop Flexopecten glaber were underwent in this study. Results show that food deprivation induces a diminution of the amounts of the EPA (C20:5n-3) and the DHA (C22:6n-3) as well as the n-3/n-6 ratio. Meanwhile, a selective retention, in terms of increase of percentage, of the AA (C20:4n-6) in unfed specimens ...

This experiment was conducted to determine the effect of different vegetable oil types on broiler energy expenditure, abdominal fat deposition and fatty acid profile of breast and thigh. A total number of 300 un-sexed day-old cobb 500 broiler chickens were used in a completely randomized design, consisted of five treatments (five different vegetable oil sources including soy, flaxseed, canola, ...

The influence of pH (6.0-9.0), natural organic matter (NOM) (0-10 mg C/L) and ionic strength (IS) (1.7-40 mM) on 14 nm CeO₂ NP aggregation and ecotoxicity towards the alga Pseudokirchneriella subcapitata was assessed following a central composite design. Mean NP aggregate sizes ranged between 200 and 10000 nm. Increasing pH and IS enhanced aggregation, while increasing NOM decreased mean aggreg...

It has been brought to our attention that there were a number of typographical errors in one section of our recent article [1] published in December 2005. All corrections apply to the section entitled, 'Biochemical rationale; Eicosanoids: cyclo-oxygenase pathway'. The second paragraph should read: The usual substrate for the COX isozymes is the n6 LC PUFA arachidonic acid (AA; C20:4n-6). Eicosa...

Hydrogenated small fullerenes (Cn, n < 60) are of interest as potential astrochemical species, and intermediates in hydrogen-catalysed fullerene growth. However, the computational identification key stable species is difficult due to vast configurationally space structures. In this study, we explored routes predict hydrogenated fullerenes. We showed that neither local geometry nor electronic...
