ment in adolescent rats, and RUPS exposure causes blunting of alcohol's negative effects on contextual fear conditioning.Our previous study showed that propane-2-sulfonic acid octadec-9-enyl-amide (N15), a novel peroxisome proliferator-activated receptor α and γ (PPARα/γ) dual agonist, inhibits inflammatory responses in tumor necrosis factor alpha (TNFα)-induced vascular endothelial cells or lipopolysaccharide (LPS)-induced human myeloid leukemia mononuclear cells-1. However, little is known about whether N15 applies to other pathological or neuroinflammatory conditions. In the present study, we detected the effect of N15 on the LPS-induced neuroinflammatory response in mice and further investigated whether the effect of N15 on neuroinflammation and neuronal cells survival was related to PPARα/γ dual pathways. We found that N15 decreased the mRNA expression of the proinflammatory cytokines IL-1β, IL-6, TNFα, inducible nitric oxide synthase and cyclooxygenase-2; inhibited microglial activation; and ameliorated neuronal apoptosis in the hippocampus and cortex of LPS-induced mice. In addition, PPARα antagonist MK886 or PPARγ antagonist T0070907 partially eliminated the effect of N15. These results demonstrate that N15 exerts an anti-inflammatory effect, at least in part, by enhancing PPARα/γ dual signaling. Our study reveals that N15 may be a promising neuronal protective drug for the treatment of neuroinflammatory diseases.Eriodictyol, a natural flavonoid compound identified in numerous medicinal plants, has been reported to have anti-inflammatory, antioxidative and antiproliferative activities and exert protective effects on the neurons, thus drawing attention to its therapeutic potential. However, the effect of eriodictyol on depression remains unclear. In the present study, we investigated the behavioral effects of chronic eriodictyol treatment in rat models of depression induced by lipopolysaccharide (LPS, 1 mg/kg) challenge and chronic unpredictable mild stress (CUMS). We found that chronic eriodictyol (10, 30, and 100 mg/kg) treatment by oral gavage once daily for 14 days dose-dependently produced antidepressant effect in the forced swim test (FST), but did not alter locomotor activity in the open field test. Moreover, oral administration with eriodictyol (100 mg/kg) for 28 days reversed the depressive- and anxiety-like behaviors induced by LPS or CUMS, as evidenced by significantly increased sucrose preference in the sucrose preference test, reduced immobility time in the FST, and reduced latency to feeding in the novelty-suppressed feeding test. In addition, co-administration of subthreshold doses of eriodictyol (30 mg/kg) and transient potential vanilloid 1 receptor antagonist capsazepine (1.5 mg/kg) produced a synergistic effect in these tests. Chronic eriodictyol administration at a dose of 100 mg/kg also rescued the memory deficits induced by CUMS as indicated by the increased exploration index in the novel object recognition test. Altogether, these results demonstrate that eriodictyol attenuates depressive- and anxiety-like behaviors and cognitive impairments in rats, and might be a potential therapeutic avenue for depression.Acupuncture is widely used to treat various neurodegenerative diseases and can effectively improve cognitive and memory states in Alzheimer's disease. However, its mechanism is unclear. We speculated that the effect of acupuncture on cognitive function may be associated with reductions in the levels of Aβ and phosphorylated tau in the brain. In this experiment, 60 male Sprague-Dawley rats were randomly divided into control, model, electroacupuncture and nonacupoint groups. We perform electroacupuncture at Shenting (GV24) and bilateral Benshen (GB13) acupoints once a day for 4 weeks in electroacupuncture group (with 1 day of rest after every 6 days of treatment). The electroacupuncture group showed a better performance in cognitive-related behavior tests and significantly lowers the levels of Aβ, p-tau (s396) and p-tau (s404) in the hippocampus. These results may suggest that electroacupuncture at the GV24 and bilateral GB13 acupoints might improve cognitive functions in Alzheimer's disease by decreasing the levels of Aβ, p-tau (s396) and p-tau (s404) in the brain as these proteins are the main causes of neurological damage and cognitive dysfunction during the pathogenesis underlying Alzheimer's disease.
Objective Approximately 50% of children with autism exhibit severe tantrums, defiance, and/or aggression. We propose that the Disruptive Behavior Diagnostic Observation Schedule (DB-DOS)-a standardized clinical observation modeled after, and complementary to, the Autism Diagnostic Observation Schedule (ADOS)-could enhance earlier identification of disruptive behavior (DB) in autism populations and inform treatment planning. Methods We adapted the DB-DOS for children with autism based on expert input and preliminary feasibility testing to accommodate varying cognitive and social communication capacities and increase the likelihood of observing DB in this population. Thereafter, we concurrently administered the modified DB-DOS and the ADOS to 12 children with autism aged 36 to 50 months. Elamipretide mw Results Overall, children exhibited greater DB, especially behavioral regulation challenges, during the DB-DOS than during the ADOS. Conclusion The use of a developmentally sensitive standardized observation tool that pressesildren with autism aged 36 to 50 months. Results Overall, children exhibited greater DB, especially behavioral regulation challenges, during the DB-DOS than during the ADOS. Conclusion The use of a developmentally sensitive standardized observation tool that presses for DB to complement standardized observations such as the ADOS shows promise for enabling more precise research on targeted DB interventions. Such a tool holds promise as a reliable and efficient method of identifying comorbid DB disorders in the autism population.
High-intensity endurance training can elicit profound cardiac adaptations; however, the current evidence as to its impact on the proximal aorta is limited. The purpose of this study was to investigate the morphological and functional characteristics of the proximal aorta in endurance athletes.

Fifteen young male middle- and long-distance runners were compared with 19 age- and sex-matched sedentary control participants. CINE phase-contrast magnetic resonance imaging was used to measure blood flow velocities and cross-sectional areas of the ascending and proximal descending aorta. Aortic blood pressure was measured simultaneously during the phase-contrast magnetic resonance imaging scan using a generalized transfer function. Maximal oxygen uptake (V˙O2max) was measured in the athletes. Left ventricular morphology was assessed in a subgroup of participants (n = 16) with cardiac magnetic resonance imaging.

The athlete group exhibited an average V˙O2max of 69.5 ± 3.1 mL·kg-1⋅min-1, which is above the 90th percentile of men with similar age according to the American College of Sports Medicine guideline.
