Understanding parenting from both parent and child perspectives is critical to child clinical and developmental research. Similarities and differences between parents' and children's reports can be highly informative, but only if they derive from psychometrically sound measures that assess the same parenting constructs. We examined the psychometric properties of the child and parent forms of the Parenting Perception Inventory (Bruce et al., 2006), which measures perceptions of two higher-order dimensions: positive, warm, supportive parenting; and negative, harsh, critical parenting...

We report the Ni-catalyzed Suzuki-Miyaura coupling of aliphatic amide derivatives. Prior studies have shown that aliphatic amide derivatives can undergo Ni-catalyzed carbon-heteroatom bond formation but that Ni-mediated C-C bond formation using aliphatic amide derivatives has remained difficult. The coupling disclosed herein is tolerant of considerable variation with respect to both the amide-based substrate and the boronate coupling partner and proceeds in the presence of heterocycles and epimerizable stereocenters...

Genomes of varying sizes have been sequenced with next generation sequencing platforms. However, most reference sequences include draft unordered scaffolds containing chimera caused by mis-scaffolding. A BioNano genome (BNG) optical map was constructed to improve the previously sequenced flax genome (Linum usitatissimum L., 2n=30, ~373 Mb), which consisted of 3,852 scaffolds larger than 1 kb and totalling 300.6 Mb. The high resolution BNG map of cv. CDC Bethune totalled 317 Mb and consisted of 251 BNG contigs with an N50 of 2...

OBJECTIVE: The hubs of the brain network play a key role in integrating and transferring information between different functional modules. However, whether the changed pattern in functional network hubs contributes to the onset of leg discomfort symptoms in restless legs syndrome (RLS) patients remains unclear. Using resting-state functional magnetic resonance imaging (rs-fMRI) and graph theory methods, we investigated whether alterations of hubs can be detected in RLS. METHODS: First, we constructed the whole-brain voxelwise functional connectivity and calculated a functional connectivity strength (FCS) map in each of 16 drug-naive idiopathic RLS patients and 26 gender- and age-matched healthy control (HC) subjects...

BACKGROUND: Illicit use of high-potency synthetic opioids has become a global issue over the past decade. This misuse is particularly pronounced in British Columbia, Canada, where a rapid increase in availability of fentanyl and other synthetic opioids in the local illicit drug supply during 2016 led to a substantial increase in overdoses and deaths. In response, distribution of take-home naloxone (THN) overdose prevention kits was scaled up (6·4-fold increase) throughout the province...

BACKGROUND: Psychological well-being in adolescence has always been a focus of public attention and academic research. Ryff's six-factor model of psychological well-being potentially provides a comprehensive theoretical framework for investigating positive functioning of adolescents. However, previous studies reported inconsistent findings of the reliability and validity of Ryff's Scales of Psychological Well-being (SPWB). The present study aimed to explore whether Ryff's six-factor model of psychological well-being could be applied in Chinese adolescents...

The evaluation of decision aids and support interventions requires a multi-attribute index which can be calculated for both aid and comparator/s. The Decision Conflict Scale (DCS) is such an index and has been widely used in this context, the recent Cochrane review Decision aids for people facing health treatment or screening decisions reporting its use in 63 of the 105 studies included. However, while the DCS may be a valid measure for the eponymous construct - decision conflict - it lacks both content and construct validity for the evaluation of decision aids...

Dysfunctional conflict resolution behaviors in couples have been long recognized as markers of relationship maladjustment and are, consequently, frequent targets of couple therapy. The process of flooding may play a role. Flooding is the subjective sense of being overwhelmed by the partner's negative affect, which is perceived as unexpected and intense, and feeling as though one's information processing is impaired. It has been theorized that flooding is so aversive as to lead to maladaptive conflict behaviors (e...

To study the effect of proteases on pullulanase production, six protease-encoding genes (nprB, bpr, mpr, epr, vpr, and wprA) in the genome of Bacillus subtilis strain WS5, which already lacks the protease-encoding genes nprE and aprE, were sequentially disrupted using a CRISPR/Cas9 system. This created strains WS6-WS11, respectively. The strains WS3 (none) and WS4 (ΔnprE) were constructed earlier. After addition of expression plasmid pHYPULd4 into the strains WS3-WS11, the pullulanase production levels of the resulting strains (WS3PUL-WS11PUL, respectively) were investigated in shake-flask cultivations and recombinant strain WS5PUL produced the highest pullulanase activity (148...

Liver is one of the most important organ in the body. But there are many limitations about liver transplantation for liver failure. It is quite important to develop the xenogeneic biological liver for providing an alternation to transplantation or liver regeneration. In this paper, we proposed a method to construct a novel kind of agarose 3D-culture concave microwell array for spheroids formation of hepatic cells. Using the 3D printing method, the microwell array was fabricated with an overall size of 6.4 mm × 6...

Nervous necrosis virus (nodavirus) has been responsible for mass mortalities in aquaculture industry worldwide, with great economic and environmental impact. A rapid low-cost test to identify nodavirus genotype could have important benefits for vaccine and diagnostic applications in small- and medium-scale laboratories in both academia and fish farming industry. A dual lateral flow biosensor for simultaneous detection of the most prevalent nodavirus genotypes (RGNNV and SJNNV) was developed and optimized. The dual biosensor consisted of two antibody-based test zones, indicative of each genotype, and a control zone...

Restoration of speech communication for locked-in patients by means of brain computer interfaces (BCIs) is currently an important area of active research. Among the neural signals obtained from intracranial recordings, single/multi-unit activity (SUA/MUA), local field potential (LFP), and electrocorticography (ECoG) are good candidates for an input signal for BCIs. However, the question of which signal or which combination of the three signal modalities is best suited for decoding speech production remains unverified...
