The study also reveals a state-specific variability of the influence of the built environment on the severity of DD related crashes. These findings provide a comprehensive understanding of the severity of DD related crashes for transportation safety planners or policymakers to develop customized policy recommendations, such as designing policies or roadway safety treatments, to curb the negative consequences of distracted driving.Chronic pain is a significant public health problem associated with functional impairment, increased medical expenditures, and opioid misuse. Recent work has suggested that certain transdiagnostic psychosocial factors may be more important than pain intensity to better understand pain and opioid outcomes. Specifically, pain-related anxiety, anxiety sensitivity, emotion dysregulation, and distress tolerance have all been uniquely associated with both pain and opioid outcomes across a range of samples. Yet, no work has examined how these transdiagnostic constructs relate to pain and opioid misuse when accounting for the other constructs. Therefore, the current study employed two independent sample of adults with chronic pain to examine (1) the construct independence of each of these factors using exploratory structural equation modelling (ESEM) and (2) how each of these constructs relates to pain and opioid outcomes in latent structural models. Results from Study 1 provided empirical support for construct independence of the transdiagnostic constructs. Findings from Study 2 indicated that pain-related anxiety was most strongly related to pain intensity, interference, and pain-related negative affect, anxiety sensitivity with opioid misuse, and emotion dysregulation with all studied criterion variables. The current results highlight the importance of assessing and targeting transdiagnostic constructs among adults with pain.A cognitive intervention that may reduce weight and caloric intake is inhibitory control training (ICT; having individuals repeatedly withhold dominant responses to unhealthy food images). We conducted a randomized controlled trial where 100 individuals with overweight or obesity were assigned to complete a generic (n = 48) or food-specific ICT (n = 52) training four times per week for four weeks. Weight and caloric intake were obtained at baseline, four-weeks, and 12-weeks. Participants also completed high-calorie and neutral go/no-go tasks while N2 event-related potential (ERP) data, a neural indicator of inhibitory control, was measured at all visits. Results from mixed model analyses indicate that neither weight, caloric intake, nor N2 ERP component amplitude towards high-calorie foods changed at post-testing or at the 12-week follow up. Regression analyses suggest that individuals with smaller N2 difference amplitudes to food may show greater weight loss and reductions in caloric intake after a generic ICT, while individuals with larger N2 difference amplitudes to food may show greater weight loss and reductions in caloric intake after a food-specific ICT. Overall, multiple food-specific or generic ICT sessions over the course of a four-week period do not affect overall weight loss, caloric intake, or N2 ERP amplitude.Temperature is an important environmental factor in the living environment of crustaceans. Changes in temperature can affect their normal growth and metabolism and even cause bacterial disease. Currently, the potential anti-reverse molecular reaction mechanism of crustaceans during high-temperature conditions has not yet been fully understood. Therefore, in this study, we characterised the transcriptome of Procambarus clarkii using RNA sequencing and performed a comparison between super-high-temperature treated samples and controls. After assembly and annotation, 81,097 unigenes with an average length of 069 bp and 358 differentially expressed genes (DEGs) were identified. Among these DEGs, 264 were differentially upregulated and 94 were differentially downregulated. To obtain comprehensive gene function information, we queried seven databases, namely, Nr, Nt, Pfam, KOG, Swiss-Prot, KEGG, and GO to annotate gene functions. Transcriptome analysis revealed that the identified DEGs have significant effects on immune-related pathways, including lysosomal and phagosomal pathways, and that super-high-temperature conditions can cause disease in P. clarkii. Some significantly downregulated genes are involved in oxidative phosphorylation and the PPAR signalling pathway; this suggests a metabolic imbalance in P. clarkia during extreme temperature conditions. In addition, elevated temperature changed the expression patterns of key apoptosis genes XIAP, CASP2, CASP2, CASP8, and CYTC, thereby confirming that high-temperature conditions caused immune disorders, metabolic imbalance, and, finally, triggered apoptosis. Our results provide a useful foundation for understanding the molecular mechanisms underlying the responses of P. β-Glycerophosphate in vivo clarkii during high-temperature conditions.The widely used polyketide pharmaceuticals in medicine and agriculture are mainly produced by Streptomyces species. These compounds, as secondary metabolites, are not involved in essential cellular processes and are usually produced during the stationary phase of fermentation. Consequently, their yields and productivities are often low and frequently limited by the availability of the precursors. The precursor pathways, therefore, are key entities for synthetic biology-driven design and optimization. We discuss recent advances in precursor engineering, in both Streptomyces and other bacteria, focusing on the diverse native and heterologous precursor pathways that could be rewired for polyketide titer improvement. We also highlight the coordination of other required factors to direct the precursors towards polyketide biosynthesis. The precursor-supply enhancement tools and strategies covered in this review will facilitate the design and construction of synthetic Streptomyces ‘cell-factories’ for efficient polyketide production.We tested the Cognitive Reserve (CR) hypothesis in Amyotrophic Lateral Sclerosis (ALS), enrolling 111 patients, using education as CR proxy, 18F-FDG-PET to assess brain damage, and ECAS to measure cognition. Education was regressed out against brain metabolism, including age, sex, spinal/bulbar onset, ALSFRS-R, and ECAS as covariates. Clusters showing a significant correlation were used as seed regions in an interregional correlation analysis (IRCA) in the ALS group and in 40 controls. In the ALS group, we found a negative correlation between brain metabolism and education in the right anterior cingulate and bilateral medial frontal gyrus. In the IRCA in the ALS group, the medial frontal cluster metabolism positively correlated with that of frontotemporal regions (right > left), bilateral caudate nuclei, and right insula, and negatively correlated with that of corticospinal tracts, cerebellum, and pons. In controls, the IRCA showed significant positive correlations in the same regions but less extended. Our results agree with the CR hypothesis.
