The purpose of this study was to investigate the effect neuroticism has on the relationship between alcohol use severity and amygdala connectivity. Previous studies have indicated that amygdala connectivity and negative affect play a role in the cycle of addiction, and that neuroticism, which shares similar qualities with negative affect, is also related to amygdala connectivity, but the role neuroticism plays in mediating the relationship between AUD and amygdala connectivity has not been examined. To complete this study, 158 participants (58 female) enrolled in studies through NIAAA (National Institutes of Alcohol Abuse and Alcoholism) underwent resting state functional MRI (rs-fMRI) scans. The Alcohol Use Disorders Identification Test (AUDIT) was used to quantify alcohol use severity and the Revised NEO Personality Assessment (NEO PI-R) was used to quantify levels of neuroticism. A whole brain analysis was conducted to investigate the relationship of rs-fMRI amygdala connectivity with AUDIT and NEO neuroticism scores. A latent variable model (LVM) was used to measure the mediation effect of neuroticism on alcohol use severity and rs-fMRI amygdala connectivity. The whole brain analysis showed a positive relationship between right amygdala-right temporal fusiform gyrus connectivity and AUDIT scores and a negative relationship between left amygdala-left temporal parietal junction (TPJ) connectivity and NEO neuroticism scores. The indirect effect of neuroticism was significant for the LVMs of left amygdala connectivity with the nucleus accumbens (NAcc), posterior insula, and dorsal anterior cingulate cortex (dACC). These results suggest that personality plays an important role in the cycle of addiction. Published by Elsevier B.V.Cerebrospinal fluid (CSF) total tau (t-tau) and tau protein phosphorylated at threonine 181 (p181tau) are established biomarkers for Alzheimer's disease (AD). Herein, we measured t-tau and p181tau to evaluate novel enzyme-linked immunosorbent assays (ELISAs) using 72 CSF samples including from patients with AD with dementia (ADD) and various neurodegenerative diseases. Our assay system showed good correlations with widely used ELISA systems for t-tau and p181tau and showed that serum and hemoglobin contamination in CSF samples did not decrease sensitivity. Significant increases in both t-tau and p181tau levels were observed in ADD. These findings suggested that our ELISAs were reliable assays for CSF t-tau and p181tau similar to commonly used ELISAs. Compact nanohybrids can potentially unite various therapeutic features and reduce side effects for precise cancer therapy. However, the poor accumulation and limited tumor penetration of drugs at the tumor impede the manifestation of nanomedicine. We developed a rabies virus glycoprotein (RVG)-amplified hierarchical targeted hybrid that acts as a stealthy and magnetolytic carrier that transports dual tumor-penetrating agents incorporating two drugs (boron-doped graphene quantum dots (B-GQDs)/doxorubicin and pH-responsive dendrimers (pH-Den)/palbociclib). The developed RVG-decorated hybrids (RVG-hybrids) enhance the accumulation of drugs at tumor by partially bypassing the BBB via spinal cord transportation and pH-induced aggregation of hierarchical targeting. The penetrated delivery of dual pH-Den and B-GQD drugs to deep tumors is actuated by magnetoelectric effect, which are able to generate electrons to achieve electrostatic repulsion and disassemble the hybrids into components of a few nanometers in size. The synergy of magnetoelectric drug penetration and chemotherapy was achieved by delivery of the B-GQDs and pH-Den to orthotopic tumors, which prolonged the host survival time. This RVG-amplified dual hierarchical delivery integrated with controlled and penetrated release from this hybrid improve the distribution of the therapeutic agents at the brain tumor for synergistic therapy, exhibiting potential for clinic use. The insulin signaling pathway plays a pivotal role in glucose metabolism and metabolic homeostasis. Disruption of this pathway is commonly seen in critical illness such as following severe burn injuries where homeostatic control is lost, leading to "insulin resistance" with poor blood glucose control. The aberrant signaling pathways involved in insulin resistance following burn injury include increases in hyperglycemic stress hormones, pro-inflammatory cytokines and free radical production. Leakage of mitochondrial sequestered self-antigens and signaling between mitochondria and endoplasmic reticulum also contribute to insulin resistance. Greater understanding of molecular processes involved in burn-related insulin resistance could potentially lead to the development of novel therapeutic approaches to improve patient management. AIMS TransFORmation of IndiGEnous PrimAry HEAlthcare Delivery (FORGE AHEAD) partnered with local clinical and community teams in 11 First Nations (FN) communities across Canada to develop quality improvement (QI) initiatives aimed at improving T2DM. METHODS Pre-post mixed-methods case study design was used. The 18-month intervention included community and clinical readiness, development of a community diabetes registry and clinical system, and QI activities. Participants consisted of community members, 18 yrs and older, with diabetes. Changes in clinical outcomes and clinical practice guideline (CPG) recommendations were assessed pre and post intervention using multilevel regression (patients nested within communities) adjusted forindividual andcommunity baseline characteristics. RESULTS No significant change in HbA1c orsBP, but a small reduction indBP(-0.75 mmHg, p  less then  0.05) and LDL (-0.09 mmol/L, p  less then  0.05) was observed in 2008 adults with T2DM (mean age 60·5 (SD14·6) years; female 57·2%). BGB-8035 Individuals not at CPG targets at baseline had significant reductions in %HbA1c (N = 616) -0.40 (95%CI-0·55,-0·24),sBP (N = 561) -7·67 mmHg (95%CI-9·23, -5·72),dBP (N = 291) -7·46 mmHg (95%CI-8·69, -6·26), LDL (N = 450) -0·37mmo/l (95%CI-0·44, -0·29).Annual HbA1c (OR 1·95; 95%CI1·66, 2·29), BP (OR 1·78; 95%CI1·52, 2·09), LDL (OR 1·27; 95%CI1·10, 1·47) and CKD screening (OR 6·37; 95%CI5·16, 7·92)increased but retinopathy screening decreased (OR 0·68; 95%CI0·57, 0·82). No significant change in foot exams (OR 0·97; 95%CI0·76, 1·23) or BMI recordings (OR 0·96; 95%CI0·82, 1·12) was seen. Overall, individualsweremorelikely to receive ≥75% of CPG recommended services compared to baseline (OR 1·51; 95%CI1·27, 1·80). CONCLUSIONS FORGE AHEAD is the first Canadian study to demonstrate that a FN community-led QI intervention can lead to diabetes improvements.
