    背景:最近的研究表明,表观遗传修饰可能介导大麻的行为效应,影响exocannabinnoids对认知功能的长期影响及其在精神病症状出现中的作用。
    方法:在这篇系统范围审查中,我们评估了目前与使用大麻或外大麻素相关的表观遗传效应的证据,以及它们与行为和情绪症状的关系.我们搜索了PubMed,科克伦中部,和WebofScience,截至2022年1月,使用术语“大麻”和“表观遗传学”。“搜索产生了178篇文章,其中43篇文章进行了全面修订;审查中包括37篇文章。
    结果:收集的证据包括对人类受试者进行的观察性横断面研究和使用动物模型的实验设计,这些动物模型传达了给药剂量的差异,大麻使用评估方法和靶向表观遗传机制。九项研究进行了全基因组分析,鉴定了差异甲基化位点;这些研究中的大多数发现了全球低甲基化,以及与细胞存活和神经发育相关的基因的富集。其他研究评估了特定基因的甲基化,发现大麻暴露与Cg05575921、DNMT1、DRD2、COMT、DLGAP2,Arg1,STAT3,MGMT,和PENK,而在DNMT3a/b发现了高甲基化,NCAM1和AKT1。
    结论:该综述发现了外大麻素诱导的调节抑郁-焦虑的表观遗传变化的证据,精神病患者,和成瘾行为表型。进一步的研究将需要剂量暴露/给药均匀化和定制的基因库,以评估其作为精神疾病生物标志物的适用性。
    BACKGROUND: Recent research suggests that epigenetic modifications may mediate the behavioral effects of cannabis, influencing exocannabinnoids\' long term effects in cognitive function and its role in the emergence of psychotic symptoms.
    METHODS: In this systematic scoping review, we assessed the current evidence of epigenetic effects associated with the use of cannabis or exocannabinoid administration and their relationship with behavioral and emotional symptoms. We searched PubMed, Cochrane CENTRAL, and Web of Science, up to January 2022, using the terms \"cannabis\" and \"epigenetics.\" The search yielded 178 articles, of which 43 underwent full article revision; 37 articles were included in the review.
    RESULTS: The gathered evidence included observational cross-sectional studies conducted on human subjects and experimental designs using animal models that conveyed disparity in administration dosage, methods of cannabis use assessment and targeted epigenetic mechanisms. Nine studies performed epigenome-wide analysis with identification of differentially methylated sites; most of these studies found a global hypomethylation, and enrichment in genes related to cellular survival and neurodevelopment. Other studies assessed methylation at specific genes and found that cannabis exposure was associated with reduced methylation at Cg05575921, DNMT1, DRD2, COMT, DLGAP2, Arg1, STAT3, MGMT, and PENK, while hypermethylation was found at DNMT3a/b, NCAM1, and AKT1.
    CONCLUSIONS: The review found evidence of an exocannabinoid-induced epigenetic changes that modulate depressive-anxious, psychotic, and addictive behavioural phenotypes. Further studies will require dosage exposure/administration uniformization and a customized pool of genes to assess their suitability as biomarkers for psychiatric diseases.

    将来自各种可穿戴设备的健康和活动数据集成到研究中,提出了技术和操作挑战。真棒数据采集方法(ADAM)是一种通用的,基于Web的系统,旨在集成来自各种来源的数据并管理大规模的多阶段研究研究。作为一个数据收集系统,ADAM允许通过设备的应用程序可编程接口和移动应用程序的自适应实时问卷从可穿戴设备收集实时数据。作为临床试验管理系统,ADAM集成了临床试验管理流程,并有效地支持招聘,筛选,随机化,数据跟踪,数据报告,和整个研究过程中的数据分析。我们使用行为减肥干预研究(SMARTER试验)作为测试案例来评估ADAM系统。SMARTER是一项随机对照试验,筛选了1741名参与者,招募了502名成年人。因此,ADAM系统被有效且成功地部署,以组织和管理SMARTER试验.此外,凭借其通用的集成能力,当COVID-19大流行停止面对面接触时,ADAM系统进行了必要的切换,以无缝,及时地进行完全远程评估和跟踪。ADAM系统提供的远程原生功能将COVID-19锁定对SMARTER试验的影响降至最低。SMARTER的成功证明了ADAM系统的全面性和高效性。此外,ADAM被设计为可推广和可扩展的,以适应其他研究,只需最少的编辑,再开发,和定制。ADAM系统可以使各种行为干预和不同人群受益。
    UNASSIGNED: The integration of health and activity data from various wearable devices into research studies presents technical and operational challenges. The Awesome Data Acquisition Method (ADAM) is a versatile, web-based system that was designed for integrating data from various sources and managing a large-scale multiphase research study. As a data collecting system, ADAM allows real-time data collection from wearable devices through the device\'s application programmable interface and the mobile app\'s adaptive real-time questionnaires. As a clinical trial management system, ADAM integrates clinical trial management processes and efficiently supports recruitment, screening, randomization, data tracking, data reporting, and data analysis during the entire research study process. We used a behavioral weight-loss intervention study (SMARTER trial) as a test case to evaluate the ADAM system. SMARTER was a randomized controlled trial that screened 1741 participants and enrolled 502 adults. As a result, the ADAM system was efficiently and successfully deployed to organize and manage the SMARTER trial. Moreover, with its versatile integration capability, the ADAM system made the necessary switch to fully remote assessments and tracking that are performed seamlessly and promptly when the COVID-19 pandemic ceased in-person contact. The remote-native features afforded by the ADAM system minimized the effects of the COVID-19 lockdown on the SMARTER trial. The success of SMARTER proved the comprehensiveness and efficiency of the ADAM system. Moreover, ADAM was designed to be generalizable and scalable to fit other studies with minimal editing, redevelopment, and customization. The ADAM system can benefit various behavioral interventions and different populations.

    BACKGROUND: Understanding mild behavioral impairment, a relatively recent notion in neuropsychological studies, provides significant insights into early behavioral indicators of cognitive decline and predicts the onset of dementia in older adults. Although the importance of understanding mild behavioral impairment is acknowledged, comprehensive reviews of its correlates with older adults are limited.
    OBJECTIVE: This scoping review aims to identify the impact of mild behavioral impairment on health outcomes in older adults and the factors associated with mild behavioral impairment.
    METHODS: The review will adhere to the Joanna Briggs Institute\'s methodological principles for scoping reviews. We will include studies focusing mainly on mild behavioral impairment in older adults, with the literature on this topic being limited to the period from 2003 to the present. Other clinical diagnoses, such as cognitive impairment, Parkinson disease, and multiple sclerosis, will not be included. We will use databases including PubMed (MEDLINE), CINAHL, Web of Science, Embase, PsycINFO, Cochrane, and Scopus for relevant articles published in English. Both gray literature and peer-reviewed articles will be considered during screening. Three independent reviewers will extract data using a predefined data extraction tool. Extracted data will be presented using tables, figures, and a narrative summary aligned with review questions, accompanied by an analysis of study characteristics and categorization of mild behavioral impairment correlates.
    RESULTS: The results will be presented as a descriptive summary, structured according to the associated factors related to mild behavioral impairment, and the health outcomes. Additionally, the data on study characteristics will be presented in tabular format. An exploratory search was conducted in July 2023 to establish a comprehensive search strategy, and iterative refinements to the scoping review protocol and formalization of methods were completed. A follow-up search is planned for May 2024, with the aim of submitting the findings for publication in peer-reviewed journals.
    CONCLUSIONS: To our knowledge, this would be the first study to map the literature on the health-related factors and outcomes of mild behavioral impairment. The findings will support the development of interventions to prevent the occurrence of mild behavioral impairment and mitigate the negative outcomes of mild behavioral impairment.

    背景:抗菌素耐药性(AMR)代表了公众健康日益关注的问题。
    目的:我们试图探索与开发和实施旨在改善医院AMS的复杂干预措施相关的挑战。
    方法:我们对复杂的AMS干预进行了定性评估,行为,以及英国医院5个病房的技术组件。在开始干预后2周和7周,我们采访了25位干预用户,包括高级和初级开药者,一位高级护士,药剂师,和微生物学家。讨论的主题包括干预措施和促进者的不同要素的影响以及有效使用的障碍。访谈得到了2次病房观察的补充,以了解AMS实践。数据是音频记录的,转录,并使用NVivo12进行归纳和演绎分析。
    结果:追踪干预措施的各个组成部分的采用和影响是困难的,因为它被引入了一个充满竞争压力的环境。这些特别受影响的行为和教育成分(例如,培训,提高认识活动),通常是临时交付的。我们发现,参与式干预设计已经解决了典型的用例,但没有满足边缘案例,只有在现实世界的环境中进行干预时才变得可见(例如,不同专业和条件下处方工作流程的差异)。
    结论:以用户为中心的复杂干预措施的有效设计可以促进AMS的接受和使用。然而,并非所有的要求和潜在的使用障碍都可以在现实环境中全面实施之前完全预期或测试。
    BACKGROUND: Antimicrobial resistance (AMR) represents a growing concern for public health.
    OBJECTIVE: We sought to explore the challenges associated with development and implementation of a complex intervention designed to improve AMS in hospitals.
    METHODS: We conducted a qualitative evaluation of a complex AMS intervention with educational, behavioral, and technological components in 5 wards of an English hospital. At 2 weeks and 7 weeks after initiating the intervention, we interviewed 25 users of the intervention, including senior and junior prescribers, a senior nurse, a pharmacist, and a microbiologist. Topics discussed included perceived impacts of different elements of the intervention and facilitators and barriers to effective use. Interviews were supplemented by 2 observations of ward rounds to gain insights into AMS practices. Data were audio-recorded, transcribed, and inductively and deductively analyzed thematically using NVivo12.
    RESULTS: Tracing the adoption and impact of the various components of the intervention was difficult, as it had been introduced into a setting with competing pressures. These particularly affected behavioral and educational components (eg, training, awareness-building activities), which were often delivered ad hoc. We found that the participatory intervention design had addressed typical use cases but had not catered for edge cases that only became visible when the intervention was delivered in real-world settings (eg, variations in prescribing workflows across different specialties and conditions).
    CONCLUSIONS: Effective user-focused design of complex interventions to promote AMS can support acceptance and use. However, not all requirements and potential barriers to use can be fully anticipated or tested in advance of full implementation in real-world settings.

    男男性行为者(MSM)之间的性传播已成为主要的HIV传播途径。然而,在中国,已经进行了有限的研究来调查交易性行为(TS)与HIV发病率之间的关系。
    本研究旨在调查在中国从事TS(MSM-TS)的MSM中的HIV发病率,并区分与HIV发病率相关的社会人口统计学和性行为危险因素。
    我们使用基于微信的平台进行了一项前瞻性队列研究,以评估中国MSM的HIV发病率。包括宁波的MSM-TS,从2019年7月至2022年6月招募。每次访问,参与者在接受线下HIV检测之前,在微信平台上完成了一份问卷并预约了HIV咨询和检测.HIV发病率密度计算为HIV血清转化数除以随访的人年(PYs),进行单因素和多因素Cox比例风险回归,以确定与HIV发病率相关的因素.
    共有932名参与者贡献了630.9个PYs的随访,在研究期间观察到25例HIV血清转化,导致每100个PYs的HIV发病率估计为4.0(95%CI2.7-5.8)。MSM-TS中的HIV发病率为每100个PYs18.4(95%CI8.7-34.7),显着高于不从事TS的MSM中每100个PYs3.2(95%CI2.1-5.0)的发生率。在调整了社会人口统计学特征后,与HIV感染相关的因素是MSM-TS(调整后的风险比[AHR]3.93,95%CI1.29-11.93),与男性发生无保护性行为(aHR10.35,95%CI2.25-47.69),并且在过去6个月中有多个男性性伴侣(aHR3.43,95%CI1.22-9.64)。
    这项研究发现,宁波的MSM-TS中HIV的发病率很高,中国。与艾滋病毒发病率相关的危险因素包括TS,与男人发生无保护的性行为,有多个男性性伴侣.这些发现强调需要制定有针对性的干预措施,并提供全面的医疗服务,艾滋病毒检测,和MSM的暴露前预防,特别是那些从事TS的人。
    UNASSIGNED: Sexual transmission among men who have sex with men (MSM) has become the major HIV transmission route. However, limited research has been conducted to investigate the association between transactional sex (TS) and HIV incidence in China.
    UNASSIGNED: This study aims to investigate HIV incidence and distinguish sociodemographic and sexual behavioral risk factors associated with HIV incidence among MSM who engage in TS (MSM-TS) in China.
    UNASSIGNED: We conducted a prospective cohort study using a WeChat-based platform to evaluate HIV incidence among Chinese MSM, including MSM-TS in Ningbo, recruited from July 2019 until June 2022. At each visit, participants completed a questionnaire and scheduled an appointment for HIV counseling and testing on the WeChat-based platform before undergoing offline HIV tests. HIV incidence density was calculated as the number of HIV seroconversions divided by person-years (PYs) of follow-up, and univariate and multivariate Cox proportional hazards regression was conducted to identify factors associated with HIV incidence.
    UNASSIGNED: A total of 932 participants contributed 630.9 PYs of follow-up, and 25 HIV seroconversions were observed during the study period, resulting in an estimated HIV incidence of 4.0 (95% CI 2.7-5.8) per 100 PYs. The HIV incidence among MSM-TS was 18.4 (95% CI 8.7-34.7) per 100 PYs, which was significantly higher than the incidence of 3.2 (95% CI 2.1-5.0) per 100 PYs among MSM who do not engage in TS. After adjusting for sociodemographic characteristics, factors associated with HIV acquisition were MSM-TS (adjusted hazard ratio [aHR] 3.93, 95% CI 1.29-11.93), having unprotected sex with men (aHR 10.35, 95% CI 2.25-47.69), and having multiple male sex partners (aHR 3.43, 95% CI 1.22-9.64) in the past 6 months.
    UNASSIGNED: This study found a high incidence of HIV among MSM-TS in Ningbo, China. The risk factors associated with HIV incidence include TS, having unprotected sex with men, and having multiple male sex partners. These findings emphasize the need for developing targeted interventions and providing comprehensive medical care, HIV testing, and preexposure prophylaxis for MSM, particularly those who engage in TS.

    目的:美国头痛协会制定了基于证据的偏头痛治疗指南,并发现了支持行为疗法(BT)的A级证据。了解BT的机制可以改善偏头痛的管理并减轻其负担。
    方法:我们进行了叙述性综述,以定义BT的当前证据并确定其在偏头痛管理中的有用性。
    结果:信息来自116种出版物,其中56个是通过PubMed(2011-2020)的直接搜索检索到的,其余的是由作者选择来完成内容。BT可能通过减少交感神经系统对压力的反应和增加疼痛耐受性来减少偏头痛的影响。在与头痛相关的环境中行动可以得到改善,以及头痛持续时间和自我效能。移动健康和电子健康应用程序等应用程序可以帮助实施更健康的生活方式。关于药物过度使用,BT似乎是一个不错的选择,与药物预防相似的结果。使用BT的优点是没有不良影响,并且在儿童中不受限制地使用,其中BT被认为比标准化药典更有效。
    结论:BT是一种有趣的工具,可用作偏头痛的附加疗法。通过BT,偏头痛患者的自主性和赋权得到增强。BT可能不能治愈偏头痛,但它可以帮助减轻疼痛的严重程度,残疾,和偏头痛的影响,在药典的感知作用中加入情感和认知方法。因此,一种更好的治疗偏头痛的方法,实施具体的治疗管理,可以改善偏头痛的控制。
    OBJECTIVE: The US Headache Consortium developed evidence-based guidelines for the treatment of migraine and found grade A evidence in support of behavior therapy (BT). Understanding the mechanisms of BT may improve the management of migraine and reduce its burden.
    METHODS: We performed a narrative review to define the current evidence of BT and determine its usefulness in migraine management.
    RESULTS: The information was obtained from 116 publications, with 56 of them retrieved through direct searches in PubMed (2011-2020) and the remainder selected by the authors to complete the content. BT might reduce migraine impact by decreasing the sympathetic nervous system\'s response to stress and increasing pain tolerance. Acting in headache-related surroundings can be improved, together with headache duration and self-efficacy. Applications such as mobile health and electronic health applications can help to carry out healthier lifestyle patterns. Regarding medication overuse, BT seems to be a good choice, with similar results to pharmacological prophylaxis. Advantages of using BT are the lack of adverse effects and the unrestricted use in children, where BT is postulated to be even more effective than the standardized pharmacopeia.
    CONCLUSIONS: BT is an interesting tool that can be used as an add-on therapy in migraine. Through BT, the autonomy and empowerment of migraine patients is enhanced. BT may not cure migraine, but it could help to reduce pain severity perception, disability, and migraine impact, adding an emotive and cognitive approach to the perceptive role of pharmacopeia. Thus, a better approach in migraine, implementing specific therapeutic management, can improve migraine control.

    面临卫生差距的农村服务不足地区获得卫生资源的机会不平等。到美国SARS-CoV-2感染的第三和第四波,COVID-19检测减少了,更依赖家庭测试,那些寻求测试的人大多是有症状的。
    这项研究确定了与COVID-19测试相关的因素,这些个体是在西弗吉尼亚州对服务不足人群的快速加速诊断2期(RADx-UP2)测试地点观察到的有症状和无症状的个体。
    人口统计学,临床,和行为因素是通过调查从被测试个体中收集的。Logistic回归用于确定与在测试部位出现症状的个体存在相关的因素。进行了空间自相关的全局测试,以检查有症状的个体与邮政编码测试的总个体的比例。创建了双变量地图,以显示较高比例的受测试个体之间的地理分布,这些个体是健康的症状和社会决定因素。
    在预测因子中,存在身体(调整后的比值比[aOR]1.85,95%CI1.3-2.65)或精神(aOR1.53,95%CI0.96-2.48)合并症,与住宿/居住地点相关的挑战(aOR307.13,95%CI1.46-10,6372),没有社区社会经济困境(aOR0.99,95%CI0.98-1.00),在获得所需药物(aOR0.01,95%CI0.00-0.82)或运输(aOR0.23,95%CI0.05-0.64)方面没有挑战,社区社会经济困境与未获得所需药物之间的相互作用(aOR1.06,95%CI1.00-1.13),没有社区社会经济困难,同时没有面临与住宿/居住地相关的挑战(aOR0.93,95%CI0.87-0.99),在统计学上与首次测试访视时出现症状的个体相关.
    这项研究解决了当前COVID-19测试文献的关键限制,它几乎完全使用人群水平的疾病筛查数据来告知公共卫生应对措施。
    UNASSIGNED: Rural underserved areas facing health disparities have unequal access to health resources. By the third and fourth waves of SARS-CoV-2 infections in the United States, COVID-19 testing had reduced, with more reliance on home testing, and those seeking testing were mostly symptomatic.
    UNASSIGNED: This study identifies factors associated with COVID-19 testing among individuals who were symptomatic versus asymptomatic seen at a Rapid Acceleration of Diagnostics for Underserved Populations phase 2 (RADx-UP2) testing site in West Virginia.
    UNASSIGNED: Demographic, clinical, and behavioral factors were collected via survey from tested individuals. Logistic regression was used to identify factors associated with the presence of individuals who were symptomatic seen at testing sites. Global tests for spatial autocorrelation were conducted to examine clustering in the proportion of symptomatic to total individuals tested by zip code. Bivariate maps were created to display geographic distributions between higher proportions of tested individuals who were symptomatic and social determinants of health.
    UNASSIGNED: Among predictors, the presence of a physical (adjusted odds ratio [aOR] 1.85, 95% CI 1.3-2.65) or mental (aOR 1.53, 95% CI 0.96-2.48) comorbid condition, challenges related to a place to stay/live (aOR 307.13, 95% CI 1.46-10,6372), no community socioeconomic distress (aOR 0.99, 95% CI 0.98-1.00), no challenges in getting needed medicine (aOR 0.01, 95% CI 0.00-0.82) or transportation (aOR 0.23, 95% CI 0.05-0.64), an interaction between community socioeconomic distress and not getting needed medicine (aOR 1.06, 95% CI 1.00-1.13), and having no community socioeconomic distress while not facing challenges related to a place to stay/live (aOR 0.93, 95% CI 0.87-0.99) were statistically associated with an individual being symptomatic at the first test visit.
    UNASSIGNED: This study addresses critical limitations to the current COVID-19 testing literature, which almost exclusively uses population-level disease screening data to inform public health responses.

    OBJECTIVE: To investigate thermoregulation, thermal antinociception, food/kaolin intake, fecal output, and behavior following long-acting buprenorphine preparations in rats.
    METHODS: 8 adult male rats (Rattus norvegicus) were administered long-acting SC buprenorphine (SB; 0.65 mg/kg), transdermal buprenorphine (TB; 10 mg/kg), and controls in a randomized, cross-over design.
    METHODS: Body temperature, self-injury, sedation, food/kaolin intake, fecal output, and thermal withdrawal latencies were measured 1, 4, 8, 12, 24, 48, and 72 hours posttreatment. Data analysis was performed with mixed linear models.
    RESULTS: Self-injury was present between 1 and 12 hours and 4 and 12 hours following TB and SB, respectively; sedation was associated with TB at 12 to 24 hours. Withdrawal latencies were longer in both TB and SB groups than in the control group. Food intake decreased with time in all groups but was significantly lower 24 to 48 hours after TB and 24 to 72 hours after SB versus controls. Kaolin intake decreased from baseline 48 to 72 hours in the control group. Fecal output decreased from baseline 24 to 72 hours in all groups but was significantly lower than controls 24 hours following TB and 24 to 48 hours in SB. Body temperature increased from baseline at 1 hour, 1 to 12 hours, and 1 to 24 hours in the control, TB, and SB groups, respectively, and was significantly higher than the control group 1 to 72 hours following TB and 4 to 24 hours after SB. Transdermal buprenorphine and SB in normal rats produced antinociception, self-injurious behavior, hyperthermia, and decreased food/fecal output.
    CONCLUSIONS: Although these buprenorphine preparations may produce antinociception, untoward effects such as hyperthermia, self-injurious behavior, and reduced food intake/fecal output may be seen.

    纳米技术已经显示出显著的进步,人们越来越担心NPs暴露可能引起的神经毒性和神经退行性作用。各种毒理学和流行病学研究报道,大脑是超细颗粒的主要目标。脑炎症被认为是可能的机制,可以参与神经毒性和神经退行性作用。纳米颗粒(NPs)是否会产生神经毒性并促进神经退行性变,目前尚无研究。本研究是为了调查鼻内和腹膜内暴露于氧化铈纳米颗粒(CeO2NP,通过进行一些行为测试,纳米氧化铈(NC))可能会导致脑组织中的神经毒性和神经退行性变化,生化评价,脑海马和基因表达的组织病理学检查。
    将15只小鼠分成3个相等的组。在组(I)“控制组”中,小鼠口服蒸馏水作为对照组。组(II)“NCI/P组”中的小鼠以40mg/kgb.wt,每周两次,共3周。在组(III)中,“NCI/N组”小鼠鼻内接受纳米铈(40mg/kgb.wt),每周两次,共3周。
    暴露于nanceria导致脑组织氧化损伤,丙二醛(MDA)和乙酰胆碱酯酶(AchE)水平显着增加,还原型谷胱甘肽(GSH)浓度显着降低,凋亡相关基因的上调(c-Jun:c-JunN末端激酶(JNKs),c-Fos:Fos原癌基因,AP-1转录因子亚基,c-Myc:c-骨髓细胞瘤癌基因产物或MYC原癌基因,bHLH转录因子),小鼠的运动能力和认知障碍,但腹膜内施用纳米铈后效果更明显。
    当腹膜内给予纳米二氧化铈比鼻内给予纳米二氧化铈时,纳米二氧化铈在小鼠脑组织中引起氧化损伤。
    UNASSIGNED: Nanotechnology has shown a remarkable progress nevertheless, there is a growing concern about probable neurotoxic and neurodegenerative effects due to NPs exposure. Various toxicological and epidemiological studies reported that the brain is a main target for ultrafine particles. Brain inflammation is considered as a possible mechanism that can participate to neurotoxic and neurodegenerative effects. Whether nanoparticles (NPs) may produce neurotoxicity and promote neurodegenerative is largely unstudied. The present study was done to investigate whether intranasal and intra-peritoneal exposure to cerium oxide nanoparticles (CeO2NPs, nanoceria (NC)) could cause neurotoxicity and neurodegenerative changes in the brain tissue through conducting some behavioral tests, biochemical evaluation, histopathological examinations of brain hippocampus and gene expressions.
    UNASSIGNED: Fifteen mice were separated into 3 equal groups. In group (I) \"control group\", mice were received distilled water orally and kept as a control group. Mice in the group (II) \"NC I/P group\" were injected i.p with cerium oxide nanoparticles at a dose of 40 mg/kg b.wt, twice weekly for 3 weeks. In group (III) \"NC I/N group\" mice were received nanoceria intranasally (40 mg/kg b.wt), twice weekly for 3 weeks.
    UNASSIGNED: Exposure to nanceria resulted in oxidative damage in brain tissue, a significant increase in malondialdehyde (MDA) and acetylcholinestrase (AchE) levels, significant decrease in reduced glutathione (GSH) concentration, upregulation in the apoptosis-related genes (c-Jun: c-Jun N-terminal kinases (JNKs), c-Fos: Fos protooncogene, AP-1 transcription factor subunit, c-Myc: c-myelocytomatosis oncogene product or MYC protooncogene, bHLH transcription factor), locomotor and cognitive impairment in mice but the effect was more obvious when nanoceria adminstred intraperitoneally.
    UNASSIGNED: Nanoceria cause oxidative damage in brain tissue of mice when adminstred nanoceria intraperitoneally more than those received nanoceria intranasal.

    美国的肥胖症已上升到其成年人口的42%,并且在许多其他国家也同样存在问题。尽管美国政府提供了有关健康饮食和定期锻炼的教育,行为肥胖治疗在很大程度上未能维持体重减轻。自我调节,以及运动对饮食的心理影响,有时会成为目标。虽然对运动相关的自我调节向饮食相关的自我调节的结转进行了零星的调查,目前的目的是在该领域进一步调查,以告知未来的治疗内容以改善效果。以自我调节(n=106)或教育(n=54)为重点的社区肥胖治疗的女性被评估为运动和饮食相关的自我调节的变化。负面情绪,完成练习,和重量。以自我调节为中心的组的改善明显更大。在控制与饮食相关的自我调节的初始变化后,从第3个月到第6个月,该指标的变化可通过在最初3个月治疗期间与运动相关的自我调节的变化来显著预测.这表明存在结转效应。更强的预测关系与自我调节为中心的治疗相关。在进一步的分析中,从运动变化→负面情绪→运动和饮食的自我调节的路径是显着的。与饮食相关的自我调节的增加与6、12和24个月的体重减轻显着相关。以自我调节为中心的群体有更强的关系,再次。研究结果表明,针对运动相关的自我调节可以影响饮食相关的自我调节的后期变化,以及使用与运动相关的情绪改善来增强参与者的自我调节能力。
    Obesity in the United States has risen to 42 percent of its adult population and is similarly problematic in many other countries. Although the U.S. government has provided education on healthy eating and the need to exercise regularly, behavioral obesity treatments have largely failed to sustain reductions in weight. Self-regulation, and the incorporation of exercise for its psychological impacts on eating, has sometimes been targeted. While there has been sporadic investigation into the carry-over of exercise-related self-regulation to eating-related self-regulation, the present aim is to further inquiry in that area to inform future treatment content for improved effects. Women enrolled in community-based obesity treatments with either a self-regulation (n = 106) or education (n = 54) focus were assessed on changes in exercise- and eating-related self-regulation, negative mood, completed exercise, and weight. Improvements were significantly greater in the self-regulation-focused group. After controlling for initial change in eating-related self-regulation, change in that measure from Month 3 to 6 was significantly predicted by change in exercise-related self-regulation during the initial 3 treatment months. This suggested a carry-over effect. A stronger predictive relationship was associated with the self-regulation-focused treatment. In further analyses, paths from changes in exercise→negative mood→self-regulation of both exercise and eating were significant. Increase in eating-related self-regulation was significantly associated with weight loss over 6, 12, and 24 months. The self-regulation-focused group had stronger relationships, again. Findings suggested utility in targeting exercise-related self-regulation to impact later change in eating-related self-regulation, and the use of exercise-associated mood improvement to bolster participants\' self-regulation capabilities.
