Effects of Serotonin Transporter Gene Variation on Impulsivity Mediated by Default Mode Network: A Family Study of Depression
Serotonergic neurotransmission, potentially through effects on the brain’s default mode network (DMN), may regulate aspects of attention including impulse control. Indeed, genetic variants of the serotonin transporter (5-HTT) have been implicated in impulsivity and related psychopathology. Yet it remains unclear the mechanism by which the 5-HTT genetic variants contribute to individual variability in impulse control. Here, we tested whether DMN connectivity mediates an association between the 5-HTT genetic variants and impulsivity. Participants (N = 92) were from a family cohort study of depression in which we have previously shown a broad distribution of 5-HTT variants. We genotyped for 5-HTTLPR and rs25531 (stratified by transcriptional efficiency: 8 low/low, 53 low/high, and 31 high/high), estimated DMN structural connectivity using diffusion probabilistic tractography, and assessed behavioral measures of impulsivity (from 12 low/low, 48 low/high, and 31 high/high) using the Continuous Performance Task. We found that low transcriptional efficiency genotypes were associated with decreased connection strength between the posterior DMN and the superior frontal gyrus (SFG). Path modeling demonstrated that decreased DMN–SFG connectivity mediated the association between low-efficiency genotypes and increased impulsivity. Taken together, this study suggests a gene-brain-behavior pathway that perhaps underlies the role of the serotonergic neuromodulation in impulse control
An infrared, Raman, and X-ray database of battery interphase components
Further technological advancement of both lithium-ion and emerging battery
technologies can be catalyzed by an improved understanding of the chemistry and
working mechanisms of the solid electrolyte interphases (SEIs) that form at
electrochemically active battery interfaces. However, collecting and
interpreting spectroscopy results of SEIs is difficult for several reasons,
including the chemically diverse composition of SEIs. To address this
challenge, we herein present a vibrational spectroscopy and X-ray diffraction
data library of ten suggested SEI chemical constituents relevant to both
lithium-ion and emerging battery chemistries. The data library includes
attenuated total reflectance Fourier transform infrared spectroscopy, Raman
spectroscopy, and X-ray diffraction data, collected in inert atmospheres
afforded by custom designed sample holders. The data library presented in this
work (and online repository) alleviates challenges with locating related work
that is either diffusely spread throughout the literature, or is non-existent,
and provides energy storage researchers streamlined access to vital
SEI-relevant data that can catalyse future battery research efforts.Comment: JML and RK jointly supervised this work. 26 pages, 8 figures, 8

Neutrino capture by r-process waiting-point nuclei
We use the Quasiparticle Random Phase Approximation to include the effects of
low-lying Gamow-Teller and first forbidden strength in neutrino capture by very
neutron-rich nuclei with N = 50, 82, or 126. For electron neutrinos in what is
currently considered the most likely r-process site the capture cross sections
are two or more times previous estimates. We briefly discuss the reliability of
our calculations and their implications for nucleosynthesis.Comment: 9 pages, 4 figure
3-HyÂdroxy-2-[(2E)-1-(2-hyÂdroxy-6-oxocycloÂhex-1-en-1-yl)-3-(2-methÂoxyÂphenÂyl)prop-2-en-1-yl]cycloÂhex-2-en-1-one
In the title compound, C22H24O5, each of the cycloÂhexenone rings adopts a half-chair conformation. The hyÂdroxy and carbonyl O atoms face each other and are orientated to allow for the formation of the two intraÂmolecular O—H⋯O hydrogen bonds which are typical of xanthene derivatives. In the crystal, weak interÂmolecular C—H⋯O hydrogen bonds link molÂecules into layers parallel to the ab plane
Aboriginal Urban Design for Health
Montreal’s Aboriginal population is growing rapidly, yet the community lacks a culturally safe and holistic health service center that is accessible to all Aboriginal people. On Friday, June 2, 2017 The Montreal Urban Aboriginal Health Centre (MUAHC) joined forces with Next City & Concordia University to co-create a 7-minute pitch for a 2,000 to implement the project.
