In this paper, I propose a life cycle model of painkiller consumption that combines the theory health deficit accumulation with addiction. Chronic pain is conceptualized as persistent negative shock to lifetime utility can be treated by relief medication. Individuals opioid relievers (OPR) develop addiction, which increases their demand for opioids and reduces welfare expectancy through side ef...

Oxovanadium(v)-induced dl-selective oxidative coupling of (Z)-boron enolate was demonstrated to give the corresponding 2,3-disubstituted 1,4-diketone in a good yield. High selectivity (up to 94 : 6) was attained when the reaction was performed with VO(OPr-i)2Cl at -30 °C.

Chiral CuF-catalyzed asymmetric allylation of ketones and ketimines is described. Nucleophile activation via transmetallation (allylboronate to allylcopper), which is facilitated by a cocatalyst [La(OPr)3 or LiO iPr], is key for these reactions. A CuOTf–3KOtBu–DUPHOS complex is a comparably effective catalyst that reduces the required amount of chiral phosphines.

Five series of [2Fe-2S] complexes, [Fe(2)S(2)Cl(2)(-)(x)(CN)(x)](-), [Fe(2)S(2)(SEt)(2)(-)(x)Cl(x)](-), [Fe(2)S(2)(SEt)(2)(-)(x)(CN)(x)](-), [Fe(2)S(2)Cl(2)(-)(x)(OAc)(x)](-) (OAc = acetate), and [Fe(2)S(2)(SEt)(2)(-)(x)(OPr)(x)](-) (OPr = propionate) (x = 0-2), were produced by collision-induced dissociation of the corresponding [4Fe-4S] complexes, and their electronic structures were studied ...

Previous studies using event-related potentials (ERPs) have identified a variety of brain regions that respond to rare nontarget distractor stimuli presented in the visual oddball task. By contrast, event-related functional magnetic resonance imaging (ER-fMRI) studies using similar stimuli have found little or no response in these same regions, suggesting that ER-fMRI may be less sensitive than...
