Abstract:
... A novel (μ-nitrido–diruthenium)-bridged 1-D coordination polymer was formed from reaction of K₅[Ru₂N(CN)₁₀] with [Cu(en)₂](ClO₄)₂; a similar reaction with [Cu(pn)₂][(ClO₄)₂] (pn = 1,3-diaminopropane) gave {[Cu(pn)₂]₅[Ru₂N(CN)₁₀]₂} as a discrete molecular compound; variable temperature susceptibility measurements show that there is a weak ferromagnetic interaction between the Cu(ii) ions in 1-D pol ...

Abstract:
... Better maintenance of firmness and suppression of ethylene production in 'Queen Cox' and 'Bramley' apple [Malus ×sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.] fruit was achieved by prestorage applications of 1-MCP. 1-MCP concentration, exposure time and exposure temperature ranges of 0.1 to 10.0 μL·L(-1) 1-MCP, 6 to 48 h, and 0 to 20 °C, respectively, were effective on fruit subsequently s ...

Abstract:
... Dibenzyl-g-butyrolactone and 1,2,3,4-tetrahydro-2-naphthoic acid γ(TNL) derivatives were synthesized and evaluated for cytotoxic activity against some cancer cell lines. It was found that TNL derivatives with a shorter distance between C-4 in ring A and C'-2 in ring C were more cytotoxic, while dibenzyl-γ-butyrolactones with a longer one were nearly inactive. In TNL series, presence of 3,4-dioxy g ...

They are important because they are produced solely as a result of irradiation and not any other processing method. This study investigated the formation of 2-dodecylcyclobutanone (2-DCB) and 2-tetradec-5'-enylcyclobutanone (2-TDCB) in irradiated ground beef patties from commercial and non ...

Abstract:
... Molecular orbital calculations predict that the 5-azahexenoyl radical ring closes via nucleophilic addition to the acyl carbon to afford the 5-exo product; CCSD(T)/cc-pVDZ//BHLYP/cc-pVDZ calculations predict energy barriers of 36.1 and 46.9 kJ mol⁻¹ for the exo and endo cyclization modes of the 5-azahexenoyl radical, respectively. ...

Abstract:
... The effects of 5-hydroxytryptamine (5-HT), HTF 919, a new 5-HT4 agonist, and the antagonists SB 203-186 (5-HT4) and tropisetron (5-HT3) on intestinal motility were tested in vitro on isolated preparations of horse ileum and pelvic flexure. Concentration-response curves were created by cumulative application of the agonists with or without preincubation of the antagonists. The 5-HT preparation indu ...

Abstract:
... The Up·D base-pair (5-propynyl uracil·diaminopurine) is found to be more effective at non-enzymatic transcription than the corresponding natural T·A pair; under non-enzymatic reaction conditions where the natural T·A base-pair fails, a DNA template bearing Up efficiently directs the incorporation of D into a product RNA strand. ...
