#1
Peng Liu, Run Yang, Zhigang Xu
Self-driving vehicles (SDVs) promise to considerably reduce traffic crashes. One pressing concern facing the public, automakers, and governments is "How safe is safe enough for SDVs?" To answer this question, a new expressed-preference approach was proposed for the first time to determine the socially acceptable risk of SDVs. In our between-subject survey (N = 499), we determined the respondents' risk-acceptance rate of scenarios with varying traffic-risk frequencies to examine the logarithmic relationships between the traffic-risk frequency and risk-acceptance rate...

OBJECTIVE: Children's sleep problems are associated with poorer student functioning in the school environment, including impairment in peer relationships; yet, no studies have examined sleep functioning in relation to the student-teacher relationship. The objective of this study was to examine whether child-rated total sleep problems or specific sleep problem domains (bedtime problems, nighttime problems, or daytime sleepiness) were associated with teacher-rated student-teacher closeness and conflict after controlling for student mental health symptoms known to be associated with both greater sleep problems and poorer student-teacher relationship quality...

Hybrid protein-polysaccharide particles were formed by complexation of fractal whey protein aggregates and the cationic polysaccharide chitosan. The fractal aggregates were preformed by heating native whey protein isolate at pH 7 and subsequently mixed with chitosan at pH 3 where these proteins and polysaccharides don't interact with each other. Stable dispersions of protein-polysaccharide particles were formed spontaneously when the pH was gradually increased between 4.1 and 6.8, whereas in the absence of chitosan the fractal aggregates precipitated between pH 4...

A variety of colloid stabilizers and cryoprotectants confer improved nanoparticle (NP) colloidal stability and redisperability. However, the discounted tumor targetability, delivery efficacy and possible side effects limit the application in the vascular delivery of NPs. Here we present the water-soluble silk sericin (SS) not only as a material for the preparation of NPs, but also both a dispersion stabilizer and a cryoprotectant. In the absence of any stabilizers, SS-based NPs (SSC@NPs) could resist to the serum protein adsorption, preventing the formation of particle agglomerates...

In recent years, there has been a great deal of interest in ex-vivo genetic modification of mesenchymal stem cells (MSCs) to meet various biomedical needs. Considering the self-renewal potential of MSCs, it is critically important to ensure that transfection vectors (gene carriers) do not induce genotoxicity because they could theoretically turn a single stem cell into a cancer-initiating cell. Unfortunately, there is currently no reliable, unbiased, and quantitative method to measure genotoxicity (micronuclei formation) of gene carriers directly in transfected MSCs...

OBJECTIVE: Among individual depressive symptoms, anhedonia has been reliably associated with activation of the innate immune response. However, it is unclear whether this association extends to T cell cytokines and if gender differentially affects this association. METHOD: Concentrations of T (IL-17, T-helper (Th) 1- and Th2-) and non-T cell cytokines were measured in plasma using the Bioplex Pro™ human cytokine multiplex kit in Combining Medications to Enhance Depression Outcomes (CO-MED) trial participants who provided plasma at baseline (n = 166)...

To tackle the ever-present global concern regarding human exposure to persistent organic pollutants (POPs) via food products, this study strived to indicate associations between organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in lake-fish tissue depending on the species and sampling season. Apart from the monitoring initiatives recommended in the Global Monitoring Plan for POPs, the study discussed 7 OCPs and 18 PCB congeners determined in three Cyprinidae species (rudd, carp, and Prussian carp) from Vransko Lake (Croatia), which are widely domesticated and reared as food fish across Europe and Asia...

BACKGROUND: Functional Movement Disorders (FMD) are conditions of abnormal motor control thought to be caused by psychological factors. These disorders are commonly seen in neurological practice and prognosis is often poor. No consensus treatment guidelines have been established, however the role of physical therapy in addition to psychotherapy has increasingly been recognized. This study reports patient outcomes from a multidisciplinary FMD treatment program using motor retraining (MoRe) strategies...

Suicide, self-injury, and predisposing vulnerabilities aggregate in families. Those at greatest risk often show deficits in two biologically-mediated domains: behavioral control and emotion regulation. This pilot study explored electroencephalographic and cardiovascular indices of self-regulation among typical and suicidal adolescents (n = 30/group) and biological family members (mothers, fathers, and siblings). We measured event-related potentials during a flanker task designed to evoke impulsive responding and respiratory sinus arrhythmia (RSA) at rest and during social rejection...

OBJECTIVES: Secondary caries at the tooth-restoration margins is a primary reason for restoration failure. Cracks at the margins lead to leakage which can trap bacteria, producing acids to cause caries. To date, there has been no report on developing an adhesive resin that has self-healing, antibacterial and remineralizing capabilities. The objectives of this study were to: (1) develop the first self-healing adhesive with antimicrobial and remineralizing capabilities, and (2) investigate the effects of incorporating microcapsules, dimethylaminohexadecyl methacrylate (DMAHDM) and nanoparticles of amorphous calcium phosphate (NACP) for the first time...

Asymmetric division (ASD), the unique characteristic of normal stem cells, is regarded as a stemness marker when applied to the study of cancer stem cells (CSCs). However, the role of ASD in the self-renewal of CSCs and its regulation remain largely unknown. Here, we first established a mouse Lewis lung carcinoma CSC cell line that could undergo asymmetric division (LLC-ASD cells) derived from the parental mouse Lewis lung carcinoma cancer cells (LLC-Parental cells). In vitro assessment of stemness by RT-qPCR and western blot analysis of stem cell markers, clonogenic assay (p < 0...

Silibinin, a nontoxic bioactive component in milk thistle, is used as a liver-protective drug in the clinic mainly because of its antioxidant and anti-inflammation activities. In this study, we studied the cytotoxic effects of silibinin combined with sorafenib on hepatocellular carcinoma (HCC). The results indicated that silibinin combined with sorafenib potently inhibited the proliferation of various HCC cells and induced significant apoptosis. In an HCC subcutaneous transplantation tumor model, the combination of silibinin and sorafenib significantly suppressed tumor growth compared with monotherapy...

The intrinsically disordered protein β-synuclein is known to inhibit the aggregation of its intrinsically disordered homolog, α-synuclein, which is implicated in Parkinson's disease. While β-synuclein itself does not form fibrils at the cytoplasmic pH7.4, alteration of pH and other environmental perturbations are known to induce its fibrilization. However, the sequence and structural determinants of β-synuclein inhibition and self-aggregation are not well understood. We have utilized a series of domain-swapped chimeras of α-synuclein and β-synuclein to probe the relative contributions of the N-terminal, C-terminal and the central Non-Amyloid-β Component (NAC) domains to the inhibition of α-synuclein aggregation...

Liquid water (LW) existence in pure ice below 273 K has been a controversial aspect primarily because of the lack of experimental evidences. Recently, electron paramagnetic resonance (EPR) has been used to study deeply supercooled water in a rapidly-frozen polycrystalline ice. The same technique can also be used to probe the presence of LW in polycrystalline ice that has formed through a more conventional, slow cooling one. In this context, the present study aims to emphasize that in case of an external probe involving techniques such as EPR, the results are influenced by the binary phase (BP) diagram of the probe-water system, which also predicts the existence of LW domains in ice, upto the eutectic point...

As a relatively new technology to solve the 3D structure of a protein or protein complex, the Single-Particle Reconstruction (SPR) of cryo-EM images shows much superiority and is in a rapidly developing stage. Resolution measurement in SPR, which evaluates the quality of a reconstructed 3D density map, plays a critical role for promoting methodology development of SPR and structural biology. Due to there is no benchmark map in a new structure generation, how to realize the resolution estimation of a new map is still an open problem...
