Chiral tetrakis(β-diketonate) Ln(III) complexes Δ-[NaLa(d-hfc)(4)(CH(3)CN)] (1) and Λ-[NaLa(l-hfc)(4) (CH(3)CN)] (2) (d/l-hfc(-) = 3-heptafluo-robutylryl-(+)/(-)-camphorate) are a pair of enantiomers and crystallize in the same Sohncke space group (P2(1)2(1)2(1)) with dodecahedral (DD) geometry. Typically positive and negative exciton splitting patterns around 320 nm were observed in the solid-state circular dichroism (CD) spectra of complexes 1 and 2, which indicate that their shell configurational chiralities are Δ and Λ, respectively...

The UV mixing titration, gel electrophoresis, and CD measurements indicate that oligomers with a basic sequence of 5'-d-T-(C-T-)2C-(T-)4C-(T-C-)2T form a hairpin type triplex with the target 5'-d-A-(G-A-)2G. The stability, measured UV melting temperatures, were studied in aqueous solution as functions of mC (5-methylcytidine) replacement of C, pH (4 to 7), and salt concentrations (up to 1 M). The order of stability is 5'-d-A-(G-A-)2G + 5'-d-T-(C-T-)2C-(T-)4C-(T-C-)2T < 5'-d-A-(G-A-)2G + 5'-d-T-(mC-T-)2mC-(T-)4C-(T-C-)2T approximately 5'-d-A-(G-A-)2G + 5'-d-T-(C-T-)2C-(T-)4 mC-(T-mC-)2T < 5'-d-A-(G-A-)2G + 5'-d-T-(mC-T-)2mC-(T-)4mC-(T-mC-)2T at pH 4...

The membrane-bound beta-glucan synthase from Italian ryegrass (Lolium multiflorum L.) endosperm cells has been solubilized by both non-ionic and zwitterionic detergents. A complex relationship exists between the ratio of (1----3)-, (1----4)-, and (1----3, 1----4)-beta-glucan products of the solubilized enzyme, the cations present, and the concentration of the uridine 5'-diphosphoglucose substrate. Monoclonal antibodies directed against the beta-glucan synthase complex were generated by immunization of mice with an unfractionated microsomal reparation...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
