TL;DR: This article found correlations between perceived extraversion and self-reports on items measuring the extraversion facets excitement seeking and positive emotions, and found that self-other agreement for extraversion was mediated by cheerfulness of facial expressions that was related to self-reported of extraversion but not of other personality traits.

TL;DR: 13C enrichments and coupling patterns show that the C10-terpenoid moiety is biosynthesized entirely or predominantly via the recently discovered deoxyxylulose phosphate pathway, and the phenolic moieties are generated by a polyketide-type reaction sequence.
Abstract: The biosynthesis of cannabinoids was studied in cut sprouts of Cannabis sativa by incorporation experiments using mixtures of unlabeled glucose and [1-13C]glucose or [U-13C6]glucose. 13C-labeling patterns of cannabichromenic acid and tetrahydrocannabinolic acid were analyzed by quantitative NMR spectroscopy. 13C enrichments and coupling patterns show that the C10-terpenoid moiety is biosynthesized entirely or predominantly (> 98%) via the recently discovered deoxyxylulose phosphate pathway. The phenolic moiety is generated by a polyketide-type reaction sequence. The data support geranyl diphosphate and the polyketide, olivetolic acid, as specific intermediates in the biosynthesis of cannabinoids.

TL;DR: In this paper, the Bekenstein-Hawking area law for black hole entropy in the presence of higher-derivative interactions is reviewed in the context of supersymmetric theories.
Abstract: We review modifications of the Bekenstein-Hawking area law for black hole entropy in the presence of higher-derivative interactions. In four-dimensional N=2 compactifications of string theory or M-theory these modifications are crucial for finding agreement between the macroscopic entropy obtained from supergravity and the microscopic entropy obtained by counting states in string or M-theory. Our discussion is based on the effective Wilsonian action, which in the context of N=2 supersymmetric theories is defined in terms of holomorphic quantities. At the end we briefly indicate how to incorporate non-holomorphic corrections.

TL;DR: In this article, the outer membrane channel tunnel protein TolC was found to be essential for the export of the catecholate siderophore enterobactin in E. coli.
Abstract: Escherichia coli excretes the catecholate siderophore enterobactin in response to iron deprivation. While the mechanisms underlying enterobactin biosynthesis and ferric enterobactin uptake and utilization are widely understood, nearly nothing is known about how enterobactin is exported from the cell. Mutant and high-performance liquid chromatography analyses demonstrated that the outer membrane channel tunnel protein TolC but none of the respective seven resistance nodulation cell division (RND) proteins CusA, AcrB, AcrD, AcrF, MdtF (YhiV), or the twin RND MdtBC (YegNO) was essential for enterobactin export across the outer membrane. Mutant E. coli strains with additional deletion of tolC or the major facilitator entS were growth deficient in iron-depleted medium. Strains with deletion of tolC or entS, but not with deletion of genes encoding RND transporters, excreted very little enterobactin into the growth medium. Enterobactin excretion in E. coli is thus probably a two-step process involving the major facilitator EntS and the outer membrane channel tunnel protein TolC. Quantitative reverse transcription-PCR analysis of gene-specific transcripts showed no significant changes in tolC expression upon iron depletion. However, iron starvation led to increased expression of the RND gene mdtF and a decrease in acrD.

TL;DR: Mimosine-treated neural precursor cells injected into established intracerebral CNS-1 gliomas in nude mice migrated extensively throughout the tumor and into the surrounding parenchyma beyond the tumor over 3 days, and this migratory cell delivery method has the potential to expand the range of delivery of HSV-1 vectors to tumor cells in the brain.
