    预计到2040年将影响英国160万人,每年耗资250亿英镑,痴呆症对社会提出了越来越大的挑战。这项研究,使用机器学习预测痴呆症研究的转化潜力的开创性努力,尽管痴呆症具有重大的社会和经济影响,但希望解决将基本发现缓慢转化为实际应用的问题。我们使用Dimensions数据库从1990年至2023年之间的43091英国痴呆症研究出版物中提取数据,特别是元数据(作者,出版年份,等。),论文中提到的概念和论文摘要。要为机器学习准备数据,我们应用了单热编码和词嵌入等方法。我们训练了CatBoost分类器,以预测在未来的专利或临床试验中是否会引用出版物。我们训练了几个模型变体。结合元数据的模型,概念和抽象嵌入产生了最高的性能:对于专利预测,受试者工作特性曲线下的面积为0.84和77.17%的准确度;对于临床试验预测,接收器工作特性曲线下的面积为0.81,准确度为75.11%。结果表明,将机器学习整合到当前的研究方法中可以发现被忽视的出版物,通过预测现实世界的影响和指导转化策略,加快识别有希望的研究和潜在的转化痴呆症研究。
    Projected to impact 1.6 million people in the UK by 2040 and costing £25 billion annually, dementia presents a growing challenge to society. This study, a pioneering effort to predict the translational potential of dementia research using machine learning, hopes to address the slow translation of fundamental discoveries into practical applications despite dementia\'s significant societal and economic impact. We used the Dimensions database to extract data from 43 091 UK dementia research publications between the years 1990 and 2023, specifically metadata (authors, publication year, etc.), concepts mentioned in the paper and the paper abstract. To prepare the data for machine learning, we applied methods such as one-hot encoding and word embeddings. We trained a CatBoost Classifier to predict whether a publication will be cited in a future patent or clinical trial. We trained several model variations. The model combining metadata, concept and abstract embeddings yielded the highest performance: for patent predictions, an area under the receiver operating characteristic curve of 0.84 and 77.17% accuracy; for clinical trial predictions, an area under the receiver operating characteristic curve of 0.81 and 75.11% accuracy. The results demonstrate that integrating machine learning within current research methodologies can uncover overlooked publications, expediting the identification of promising research and potentially transforming dementia research by predicting real-world impact and guiding translational strategies.

    癌症治疗方式及其进展由癌症的具体情况指导,包括其本地化的类型和站点。手术,辐射,化疗是最常用的常规治疗方法。相反,新兴的治疗技术包括免疫疗法,激素治疗,抗血管生成治疗,基于树突状细胞的免疫治疗,和干细胞疗法。免疫检查点抑制剂的抗癌特性在癌症研究领域的最新研究中引起了相当大的关注。程序性细胞死亡蛋白-1(PD-1)及其配体(PD-L1)检查点途径是活化T细胞和癌细胞之间相互作用的关键调节因子。保护后者免受免疫破坏。当配体PD-L1附着于受体PD-1时,防止T细胞破坏含有PD-L1的细胞,包括癌细胞。PD-1/PD-L1检查点抑制剂阻断它们,增强免疫反应,增强身体对肿瘤的防御能力。近年来,在使用PD-1/PD-L1靶向抗体开发抗癌疗法方面取得了令人难以置信的进展和巨大的进步。虽然免疫相关的不良反应和低反应率显着限制了这些治疗,有必要研究提高其疗效和降低其毒性的方法。这篇综述讨论了各种最新的创新纳米医学策略,如PLGA纳米粒子,碳纳米管和载药脂质体靶向PD-1/PD-L1轴治疗癌症。PD-1/PD-L1在癌症治疗中的生物学意义和纳米技术的基础,专注于纳米医学中使用的新策略,与相应的指导方针一起被广泛讨论,临床试验状态,以及此类配方的专利景观。
    Cancer treatment modalities and their progression is guided by the specifics of cancer, including its type and site of localization. Surgery, radiation, and chemotherapy are the most often used conventional treatments. Conversely, emerging treatment techniques include immunotherapy, hormone therapy, anti-angiogenic therapy, dendritic cell-based immunotherapy, and stem cell therapy. Immune checkpoint inhibitors\' anticancer properties have drawn considerable attention in recent studies in the cancer research domain. Programmed Cell Death Protein-1 (PD-1) and its ligand (PD-L1) checkpoint pathway are key regulators of the interactions between activated T-cells and cancer cells, protecting the latter from immune destruction. When the ligand PD-L1 attaches to the receptor PD-1, T-cells are prevented from destroying cells that contain PD-L1, including cancer cells. The PD-1/PD-L1 checkpoint inhibitors block them, boosting the immune response and strengthening the body\'s defenses against tumors. Recent years have seen incredible progress and tremendous advancement in developing anticancer therapies using PD-1/PD-L1 targeting antibodies. While immune-related adverse effects and low response rates significantly limit these therapies, there is a need for research on methods that raise their efficacy and lower their toxicity. This review discusses various recent innovative nanomedicine strategies such as PLGA nanoparticles, carbon nanotubes and drug loaded liposomes to treat cancer targeting PD-1/PD-L1 axis. The biological implications of PD-1/PD-L1 in cancer treatment and the fundamentals of nanotechnology, focusing on the novel strategies used in nanomedicine, are widely discussed along with the corresponding guidelines, clinical trial status, and the patent landscape of such formulations.

    专利是保护食品工业创新的重要工具。它们也是机构研究和发展的指标。大学在创造和发展创新技术方面发挥着重要作用。技术发展支持中心(CDT是技术创新中心(NIT),负责保护巴西利亚大学(UnB)学术界开发的技术。本案例分析了UnB存放的与食品相关的专利和专利申请。为此,通过专利数据库在国家工业产权研究所(INPI)机构页面上进行了搜索。结果显示主要与生物技术有关的食品领域的各种应用。在INPI工作流程中,一半的保护仍在进行中。发布的要求主要与国家遗传遗产有关。由于未付款,确定了存档过程,但我们强调这可能是NIT/CDT的战略决策。拒绝主要与缺乏新颖性或创造性步骤有关。目前,两项食品相关专利生效,平均而言,九年半的时间。虽然UnB独占多数,结果也证明了与其他大学和公司的共同所有权。最后,这项研究强调了UnB与食品行业之间可能通过技术转让建立的伙伴关系。技术转让指标指出,UNB在这一领域拥有专门知识,有潜力可供探索。这些结果有助于在开发与食品和营养相关的新技术及其向社会转让方面的战略决策。扩大规模和成熟程度的提高需要与生产部门进行更大的互动,以确保在UnB进行的研究中产生的创新技术转让。
    Patents are important tools to protect innovations in the food industry. They are also indicators of the research and development of an institution. Universities play a significant role in generating and developing innovative technologies. Center for Support to Technological Development (CDT is the Technological innovation center (NIT) that is responsible for protecting the technologies developed by the academic community of the University of Brasilia (UnB). This case study analyzes the patents and patent applications related to food deposited by the UnB. For this purpose, a search was conducted on the National Institute of Industrial Property (INPI) institutional page through the patent database. The results show diverse applications to the food area that are mainly related to biotechnology. Half of the protections are still in progress in the INPI workflow. The requirements issued were primarily related to national genetic heritage. Archiving processes were identified due to non-payment, but we highlighted that it could be a strategic decision of NIT/CDT. Rejections were mainly related to the lack of novelty or inventive steps. Currently, two food-related patents are in force that took, on average, nine and a half years to be granted. Although UnB exclusively owns the majority, the results also evidence co-ownership with other universities and companies. Finally, this study highlights possible partnerships between UnB and the food industry through technology transfer. The technology transfer indicators pointed out that UnB has expertise in this area and that there is a potential to be explored. These results contribute to strategic decision-making in developing new technologies related to food and nutrition and their transfer to society. The scale-up and the increased degree of maturity require greater interaction with the productive sector to ensure the transfer of technology for innovation arising from the research conducted at UnB.

    与气候变化相关的环境挑战正促使越来越多的国家制定碳中和目标。自2007年以来,中国采取了许多举措,到2060年实现碳中和,包括提高非化石能源的比例,发展零排放和低排放技术,并采取行动减少二氧化碳排放或增加碳汇。因此,利用2008/Q1至2021/Q4的季度数据,并应用非线性自回归分布滞后(NARDL)方法,本研究评估了中国为改善生态状况而采取的措施的有效性。研究结果表明,为减少二氧化碳排放而采取的措施并未实现其最终目的。具体而言:(i)高速铁路和新能源汽车长期不改善环境;(ii)能源领域的投资和专利,以及低碳资源,会使环境恶化;(iii)只有对环境污染治理的投资才能改善生态状况。为了实现环境可持续性,根据经验结果提出了各种政策含义。
    Climate change-related environmental challenges are prompting an increasing number of countries to set carbon-neutral targets. Since 2007, China has pursued numerous initiatives to attain carbon neutrality by 2060, including increasing the percentage of non-fossil energy, developing zero-emission and low-emission technologies, and taking actions that reduce CO2 emissions or boost carbon sinks. As a result, utilizing quarterly data from 2008/Q1 to 2021/Q4, and applying the nonlinear autoregressive distributed lag (NARDL) approach, this study evaluates the effectiveness of the measures taken by China to improve the ecological situation. The results of the study show that the measures enacted to reduce CO2 emissions did not accomplish their ultimate purpose. Specifically: (i) high-speed railways and new energy vehicles do not improve the environment in the long run; (ii) investments and patents in the energy sector, as well as low-carbon sources, will degrade the environment; (iii) only investments in the treatment of environmental pollution will improve the ecological situation. Various policy implications are suggested based on the empirical results in order to attain environmental sustainability.

    本研究试图分析专利作为引用/提到的文件,以更好地理解兴趣,这些文件在社会环境中的传播和参与,为专利的社会媒体研究(社会专利计量学)奠定基础。特别是,这项研究旨在通过分析三个要素来确定专利如何在Twitter上传播:与专利链接的推文,用户链接到专利,和与Twitter相关的专利。要做到这一点,收集并分析了所有包含至少一个链接到GooglePatents上提供的全文专利的推文,总共产生了126,815条推文(和129,001条链接),涉及86,417项专利。结果证明,多年来链接推文的数量有所增加,大概是由于创建了标准化的专利URLID以及GooglePatents和GoogleScholar的集成,发生在2015年。这些推文的参与度有限(80.2%的推文没有吸引喜欢),但自2018年以来显著增加。两个超级出版商Twitter机器人帐户(dailypatent和uspatentbot)负责所有链接推文的53.3%,虽然大多数帐户是零星的用户链接到专利作为对话的一部分。最受欢迎的专利是,到目前为止,来自美国(占Google专利的所有链接的87.5%),主要是由于两家超级出版商的影响。专利在链接到它们的推文数量方面的影响与它们的发布年份无关,收到的专利引用的状态或数量,而争议和媒体话题可能是更决定性的因素。然而,需要进一步的研究来更好地理解Twitter上围绕专利所讨论的主题,涉及的用户,以及获得的指标。鉴于链接用户和链接专利的数量不断增加,这项研究发现Twitter是衡量专利水平指标的相关来源,阐明了广大公众对专利的影响和兴趣。
    This study attempts to analyze patents as cited/mentioned documents to better understand the interest, dissemination and engagement of these documents in social environments, laying the foundations for social media studies of patents (social Patentometrics).Particularly, this study aims to determine how patents are disseminated on Twitter by analyzing three elements: tweets linking to patents, users linking to patents, and patents linked from Twitter. To do this, all the tweets containing at least one link to a full-text patent available on Google Patents were collected and analyzed, yielding a total of 126,815 tweets (and 129,001 links) to 86,417 patents. The results evidence an increase of the number of linking tweets over the years, presumably due to the creation of a standardized patent URL ID and the integration of Google Patents and Google Scholar, which took place in 2015. The engagement achieved by these tweets is limited (80.2% of tweets did not attract likes) but increasing notably since 2018. Two super-publisher twitter bot accounts (dailypatent and uspatentbot) are responsible of 53.3% of all the linking tweets, while most accounts are sporadic users linking to patent as part of a conversation. The patents most tweeted are, by far, from United States (87.5% of all links to Google Patents), mainly due to the effect of the two super-publishers. The impact of patents in terms of the number of tweets linking to them is unrelated to their year of publication, status or number of patent citations received, while controversial and media topics might be more determinant factors. However, further research is needed to better understand the topics discussed around patents on Twitter, the users involved, and the metrics attained. Given the increasing number of linking users and linked patents, this study finds Twitter as a relevant source to measure patent-level metrics, shedding light on the impact and interest of patents by the broad public.

    微针具有临床优势,能够以方便和舒适的方式在皮肤上输送复杂的药物,但尚未成功过渡到医疗实践。糖尿病是一种复杂的疾病,通常每天注射多次胰岛素,导致治疗依从性差。首先,本综述确定了微针的临床前景,在微针技术可以从工作台转换到床边之前应该解决的问题。此后,我们将糖尿病作为一个案例研究来考虑如何成功利用基于微针的技术.这里,引用胰岛素微针的出版物进行了评估,以了解是否插入效率,插入角度,成功的剂量输送,剂量可调性,材料的生物相容性和治疗稳定性正在早期研究中得到解决。此外,审查了1970-2019年的3,000多项专利,搜索词为““微针”和“胰岛素”,以了解该领域的现状。总之,早期微针研究的报告表明,与所解决的翻译因素有关的缺乏一致性。此外,更合理的设计,基于以患者为中心的方法是必要的,在监管批准后,基于微针的递送系统可以用于彻底改变糖尿病患者的生活。
    Microneedles have the clinical advantage of being able to deliver complex drugs across the skin in a convenient and comfortable manner yet haven\'t successfully transitioned to medical practice. Diabetes mellitus is a complicated disease, which is commonly treated with multiple daily insulin injections, contributing to poor treatment adherence. Firstly, this review determines the clinical prospect of microneedles, alongside considerations that ought to be addressed before microneedle technology can be translated from bench to bedside. Thereafter, we use diabetes as a case study to consider how microneedle-based-technology may be successfully harnessed. Here, publications referring to insulin microneedles were evaluated to understand whether insertion efficiency, angle of insertion, successful dose delivery, dose adjustability, material biocompatibility and therapeutic stability are being addressed in early stage research. Moreover, over 3,000 patents from 1970-2019 were reviewed with the search term \'\"microneedle\" AND \"insulin\"\' to understand the current status of the field. In conclusion, the reporting of early stage microneedle research demonstrated a lack of consistency relating to the translational factors addressed. Additionally, a more rational design, based on a patient-centred approach is required before microneedle-based delivery systems can be used to revolutionise the lives of people living with diabetes following regulatory approval.

    这篇文章认为澳大利亚,作为一个生产疫苗能力不断增强的富裕国家,有义务协助其区域(和全球)对应方实施保护其人口的疫苗接种计划。首先,本文探讨了高收入国家履行义务的能力,帮助他们的邻居,避免疫苗民族主义。这项调查涉及对全球分发疫苗的最佳道德策略的分析,以及澳大利亚在这种分销策略中可能扮演的角色。其次,这篇文章探讨了澳大利亚疫苗的知识产权格局,专注于涵盖疫苗组合物和制造技术的专利(认识到专有技术和获取材料的潜力以及影响制造能力的专利)。然后,本文讨论了澳大利亚政府在遵守《与贸易有关的知识产权协议》(TRIPS)规定的现有义务的同时,应对潜在的知识产权障碍的策略。作为对这一流行病的道德上适当的反应。本文还考虑了所谓的TRIPS放弃是否可以提供更好的选择,并得出结论认为,令人信服地披露专门知识的挑战仍然存在。
    This article posits that Australia, as an affluent country with increasing capacity to manufacture vaccines, has an obligation to assist its regional (and global) counterparts in implementing vaccination programs that protect their populations. First, the article explores the capacity of high-income nations to meet their obligations, assist their neighbours and refrain from vaccine nationalism. This inquiry involves an analysis of the optimal ethical strategy for distributing vaccines globally, and the role that Australia might play in this distribution strategy. Secondly, the article examines the intellectual property landscape for vaccines in Australia, focusing on the patents that cover vaccine compositions and manufacturing techniques (recognizing the potential for know-how and access to materials as well as patents to affect manufacturing capacity). This article then discusses the strategies the Australian Government has at its disposal to counter potential intellectual property impediments whilst complying with existing obligations under the Agreement on Trade-related Aspects of Intellectual Property Rights (TRIPS), as an ethically appropriate response to the pandemic. This article also considers whether a so-called TRIPS waiver could provide better options and concludes that the challenge of compelling disclosure of know-how remains.

    UNASSIGNED:进行了量表翻译和横断面验证研究。通过五个步骤将DDS17翻译成普通话(简体)中文:授权,正向翻译,合成,回译,和修正案。在本次会议期间,59名患者评估了翻译量表的可理解性和可读性。2021年6月7日至9月4日,对北京三家三级甲等综合医院的400名2型糖尿病患者进行了一项符合COSMIN检查表的横断面研究,中国。内容,construct,convergent,判别效度,评估了C-DDS17的可靠性(Cronbach'sα系数和项目总相关系数)。这项研究是在中国临床试验注册中心注册的项目的一部分(编号:ChiCTR2100047071).
    未经评估:在参与者中,其中33.3%(133/400)经历了中度至高度的糖尿病困扰。C-DDS17的内容有效性指数等于1.00。该量表产生了四因素结构。提取的平均方差为0.42-0.57,低于平方相关。Cronbach的α系数在总体量表中为0.88,在子量表中为0.76至0.81。校正的项目总相关系数范围为0.42至0.61。第八项(“感觉我经常因糖尿病常规而失败”)比治疗方案更适合医生困扰,但对验证结果影响不大。
    UASSIGNED:C-DDS17是评估2型糖尿病患者的糖尿病困扰的可靠且有效的工具。在临床实践和试验中,它是早期识别和管理糖尿病困扰的有前途的工具。
    UNASSIGNED: This study aimed to translate the revised 17-item Diabetes Distress Scale (DDS17, 2017) into mandarin (simplified) Chinese and validate the Chinese version of DDS17 (C-DDS17, 2021) among adult patients with type 2 diabetes in China.
    UNASSIGNED: A scale translation and cross-sectional validation study was conducted. The DDS17 was translated into mandarin (simplified) Chinese through a five-step process: authorization, forward translation, synthesis, back translation, and amendment. During this session, 59 patients assessed the understandability and readability of the translated scale. From June 7 to September 4, 2021, a cross-sectional study that adhered to the COSMIN checklist was conducted with 400 individuals with type 2 diabetes from three Class A tertiary comprehensive hospitals in Beijing, China. The content, construct, convergent, discriminant validity, and reliability (Cronbach\'s α coefficient and item-total correlation coefficients) of the C-DDS17 were evaluated. This study was a part of a project registered in the Chinese Clinical Trial Registry (no. ChiCTR2100047071).
    UNASSIGNED: Among the participants, 33.3% (133/400) of them experienced moderate to high diabetes distress. The content validity indices of the C-DDS17 equaled 1.00. The scale yielded a four-factor structure. The average variances extracted were 0.42-0.57, which was lower than squared correlations. Cronbach\'s α coefficient was 0.88 for the overall scale and ranged from 0.76 to 0.81 for sub-scales. Corrected item-total correlation coefficients ranged from 0.42 to 0.61. The eighth item (\"Feeling that I am often failing with my diabetes routine\") was better fit to physician distress than regimen distress but had little influence on the validation results.
    UNASSIGNED: The C-DDS17 is a reliable and valid instrument for assessing diabetes distress in patients with type 2 diabetes. It is a promising instrument for early identification and management of diabetes distress in clinical practice and trials.

    一个人怎么能识别,通过公开访问的网站,学术医学中心的研究活跃专家?作为案例研究,在两个学术医学中心确定了健康信息学专家:科罗拉多大学,安舒茨医学校区,和马里兰大学巴尔的摩分校。研究人员寻找了四种类型的数据:发表频率,引用频率,来自赠款的钱,和专利。根据文章发表的频率,一个中心偏爱生物信息学和心脏病学,而另一个在护理和放射学方面产生了更多的结果。有趣的是,在不同的数据集中发现了不同的模式。这种文献计量方法与通过门户网站搜索活跃研究人员的方法形成对比,该门户网站显示了特定机构的董事会认证专家。这种替代方法被尝试用于信息学和睡眠医学,文献计量法似乎产生了更好的召回率和精确度。
    How might one identify, via publicly accessible websites, research-active specialists at an academic medical center? As a case study, health-informatics specialists were identified at two academic medical centers: University of Colorado, Anschutz Medical Campus, and University of Maryland-Baltimore. Four types of data about researchers were sought: frequency of publication, frequency of citations, money from grants, and patents. Based on frequency of published articles, one center favored bioinformatics and cardiology, whereas the other produced more results in nursing and radiology. Interestingly, different patterns were found across different data sets. This bibliometric method contrasted with the method of searching for active researchers via a web portal showing board-certified specialists at a particular institution. This alternative approach was tried for informatics and sleep medicine, and the bibliometric method seemed to produce better recall and precision.
