Region of Interest (ROI) analysis of the percent signal change of six ROIs for the four experimental conditions (partner+cig, partner+pen, acquaintance+cig, and acquaintance+pen).
<p>The radius for each ROI sphere is 6 mm, VTA was 3 mm. The left line shows the location of each ROI (white circle), the right line shows the corresponding percent signal change for four experimental conditions. The center coordinates (Talarich coordinates)of each ROI sphere are: anterior cingulate cortex(ACC)(-10, 44, 9); posterior cingulate cortex(PCC)(-1,-61,17); middle frontal cortex(MFC)(8,44,14); superior frontal cortex(SFC)(-16,47,26); caudate(-13,11,2) and precuneus(14–70 41). The ROI regions ACC, PCC, MFC and SFC are defined from an activation map contrasting acquaintance+cig vs. acquaintance+pen in moderate-craving group; caudate is defined from an activation map of partner+pen vs. acquaintance+pen in moderate-craving group and precuneus is defined from an activation map of partner+cig vs. partner+pen in high-craving group.</p

Structural Insight into Tetrameric hTRPV1 from Homology Modeling, Molecular Docking, Molecular Dynamics Simulation, Virtual Screening, and Bioassay Validations
The
transient receptor potential vanilloid type 1 (TRPV1) is a heat-activated
cation channel protein, which contributes to inflammation, acute and
persistent pain. Antagonists of human TRPV1 (hTRPV1) represent a novel
therapeutic approach for the treatment of pain. Developing various
antagonists of hTRPV1, however, has been hindered by the unavailability
of a 3D structure of hTRPV1. Recently, the 3D structures of rat TRPV1
(rTRPV1) in the presence and absence of ligand have been reported
as determined by cryo-EM. rTRPV1 shares 85.7% sequence identity with
hTRPV1. In the present work, we constructed and reported the 3D homology
tetramer model of hTRPV1 based on the cryo-EM structures of rTRPV1.
Molecular dynamics (MD) simulations, energy minimizations, and prescreen
were applied to select and validate the best model of hTRPV1. The
predicted binding pocket of hTRPV1 consists of two adjacent monomers
subunits, which were congruent with the experimental rTRPV1 data
and the cyro-EM structures of rTRPV1. The detailed interactions between
hTRPV1 and its antagonists or agonists were characterized by molecular
docking, which helped us to identify the important residues. Conformational
changes of hTRPV1 upon antagonist/agonist binding were also explored
by MD simulation. The different movements of compounds led to the
different conformational changes of monomers in hTRPV1, indicating
that TRPV1 works in a concerted way, resembling some other channel
proteins such as aquaporins. We observed that the selective filter
was open when hTRPV1 bound with an agonist during MD simulation. For
the lower gate of hTRPV1, we observed large similarities between hTRPV1
bound with antagonist and with agonist. A five-point pharmacophore
model based on several antagonists was established, and the structural
model was used to screen <i>in silico</i> for new antagonists
for hTRPV1. By using the 3D TRPV1 structural model above, the pilot <i>in silico</i> screening has begun to yield promising hits with
activity as hTRPV1 antagonists, several of which showed substantial
potency
Failure to Replicate Depletion of Self-Control
<div><p>The limited resource or strength model of self-control posits that the use of self-regulatory resources leads to depletion and poorer performance on subsequent self-control tasks. We conducted four studies (two with community samples, two with young adult samples) utilizing a frequently used depletion procedure (crossing out letters protocol) and the two most frequently used dependent measures of self-control (handgrip perseverance and modified Stroop). In each study, participants completed a baseline self-control measure, a depletion or control task (randomized), and then the same measure of self-control a second time. There was no evidence for significant depletion effects in any of these four studies. The null results obtained in four attempts to replicate using strong methodological approaches may indicate that depletion has more limited effects than implied by prior publications. We encourage further efforts to replicate depletion (particularly among community samples) with full disclosure of positive and negative results.</p></div
Bio-inspired Edible Superhydrophobic Interface for Reducing Residual Liquid Food
Significant wastage of residual liquid
food, such as milk, yogurt,
and honey, in food containers has attracted great attention. In this
work, a bio-inspired edible superhydrophobic interface was fabricated
using U.S. Food and Drug Administration-approved and edible honeycomb
wax, arabic gum, and gelatin by a simple and low-cost method. The
bio-inspired edible superhydrophobic interface showed multiscale structures,
which were similar to that of a lotus leaf surface. This bio-inspired
edible superhydrophobic interface displayed high contact angles for
a variety of liquid foods, and the residue of liquid foods could be
effectively reduced using the bio-inspired interface. To improve the
adhesive force of the superhydrophobic interface, a flexible edible
elastic film was fabricated between the interface and substrate material.
After repeated folding and flushing for a long time, the interface
still maintained excellent superhydrophobic property. The bio-inspired
edible superhydrophobic interface showed good biocompatibility, which
may have potential applications as a functional packaging interface
