Atypical fatty acid metabolism has been reported in attention deficit hyperactivity disorder (ADHD), however, its relationship with temperament in this population is unclear. The current study investigated the association between blood levels of fatty acids implicated in brain structure and function (omega-3, omega-6, omega-9) and personality traits of stability (neuroticism, conscientiousness and agreeableness) and plasticity (extraversion and openness). Twenty right-handed adolescent boys with ADHD completed a self-report NEO-FFI personality questionnaire, and had fatty acid content assessed from red blood using gas chromatography. Pearson's correlations showed no significant associations between omega-3 levels and personality. After correction for multiple comparisons, Adrenic Acid (C22:4n6) was inversely associated with stability. Oleic acid (C18:1n9) was positively associated with plasticity. Results are in line with a role of fatty acids in brain function. They suggest that those fatty acids that are involved in myelination (Adrenic, Oleic) have the strongest associations with temperament in adolescents with ADHD. 相似文献

The ultrastructure of the septum in the mycelial phase of the dimorphic fungusCandida albicans has been studied both in thin sections of fixed material and in shadow casts of the chemically purified chitinous wall layer.
The septum has a 25-nm central micropore which would not allow the passage of nuclei or mitochondria, thus delimiting these
organelles within the mycelial compartments without preventing cytoplasmic continuity.

Influence of growth regulators on direct embryo formation from leaf explants of Phalaenopsis orchids
Leaf explants of two Phalaenopsis, P. amabilis and P. Nebula, were used to test the effects of auxins (2,4-D, IAA, IBA, NAA), cytokinins (2iP, BA, kinetin, TDZ, zeatin), GA3, ancymidol, polyamines (putrescine, spermine, spermidine), ACC, AgNO3 and CoCl2 on the amount of direct embryo formation on different leaf locations (the cut end, the adaxial side, the abaxial side and
the leaf tip). The results showed that there was a genotypic effect on direct embryo formation induced by cytokinins that
13.32 μM BA and 4.92 μM 2iP was the most effective in P. amabilis and P. Nebula, respectively. Besides, explant position highly affected embryogenic competence of leaf cells in both species that
the cut end showed highest embryogenic response, the adaxial side was the second, and then the abaxial side and the leaf tip.
Altogether, cytokinins tested were all effective in both species, and ACC at 20 μM had 35% of embryogenic response in P.
amabilis. However, auxins, GA3, ancymidol and polyamines were inhibitory in both species. 相似文献
