  • 文章类型: Journal Article
    专利对于将科学发现转移到有益于社会的有意义的产品至关重要。虽然学术界关注引用的数量,以根据其科学价值对学术著作进行排名,“引用的数量与可申请专利的创新的相关性无关。在公开的专利数据中探索专利与学术著作之间的关联,我们建议利用生物学中常用的统计方法来确定基因与疾病的关联.我们说明了他们在与食品安全和生态学高度相关的生物技术趋势相关的专利上的使用,即基于CRISPR的基因编辑技术(>60,000专利)和蓝藻生物技术(>33,000专利)。在时间序列分析中,通过专利数量的意外变化发现了创新趋势。从所有调查专利(~254,000份出版物)引用的全部学术著作中,我们确定了约1,000篇学术著作,这些著作在专利参考文献中统计上明显过度代表,这些著作来自与免疫学有关的不断变化的创新趋势,农业植物基因组学,和生物技术工程方法。检测到的关联与相应创新的技术要求一致。总之,所呈现的数据驱动分析工作流程可以识别创新趋势变化所需的学术著作,and,因此,对于希望评估出版物的相关性超出引用次数的研究感兴趣。
    Patents are essential for transferring scientific discoveries to meaningful products that benefit societies. While the academic community focuses on the number of citations to rank scholarly works according to their \"scientific merit,\" the number of citations is unrelated to the relevance for patentable innovation. To explore associations between patents and scholarly works in publicly available patent data, we propose to utilize statistical methods that are commonly used in biology to determine gene-disease associations. We illustrate their usage on patents related to biotechnological trends of high relevance for food safety and ecology, namely the CRISPR-based gene editing technology (>60,000 patents) and cyanobacterial biotechnology (>33,000 patents). Innovation trends are found through their unexpected large changes of patent numbers in a time-series analysis. From the total set of scholarly works referenced by all investigated patents (~254,000 publications), we identified ~1,000 scholarly works that are statistical significantly over-represented in the references of patents from changing innovation trends that concern immunology, agricultural plant genomics, and biotechnological engineering methods. The detected associations are consistent with the technical requirements of the respective innovations. In summary, the presented data-driven analysis workflow can identify scholarly works that were required for changes in innovation trends, and, therefore, is of interest for researches that would like to evaluate the relevance of publications beyond the number of citations.

    Polyphenols are a group of naturally occurring compounds that have intriguing biological activities. Among these compounds is rutin, a polyphenolic flavanol found in many plants, including passion flowers, buckwheat seed, fruits and fruit rinds, and citrus fruits (such as orange, grapefruit, lemon, and lime). Various studies have demonstrated rutin to possess antibacterial, antifungal, antiallergic, anti-inflammatory, anti-diabetic, anti-adipogenic, anti-carcinogenic, anti-apoptotic, anti-osteoporotic, radioprotective, gastroprotective, neuroprotective, and nephroprotective activities. Despite its benefits, rutin\'s therapeutic applicability is severely limited due to its low water solubility, sensitivity to oxidation, and dissolving rate. However, these problems can be overcome by employing an efficient delivery approach. An extensive number of nanocarriers can be developed for medicinal use if pre-clinical as well as human-clinical studies are completed. The current review presents an overview of effective rutin nano-formulations for targeted therapy in various health disorders. This review article discusses the clinical evidence, current status, as well as future opportunities of rutin nanocarriers for increasing rutin\'s bioactivity for possible medicinal uses.

    杂草在全球范围内造成重大农业损失,传统上,除草剂是解决这个问题的主要方法。然而,除草剂的广泛使用导致了多种杂草抗性,这可能会增加应用浓度,从而增加环境中的持久性,阻碍自然降解过程。因此,更环保的替代品,如微生物除草剂,一直在寻找。虽然这些生物除草剂很有前途,它们的功效仍然是一个挑战,其有限的商业和工业生产证明了这一点。本文回顾了基于微生物的生物除草剂的现状,并强调了无细胞代谢物提高其功效和商业吸引力的潜力。搅拌槽生物反应器被认为是最广泛用于生产规模的深层发酵。此外,使用替代碳源和氮源,如工业废物,支持循环经济。此外,本文讨论了使用生物勘探和计算机技术来识别目标代谢物的下游过程的优化,这导致了更精确和有效的生产策略。细菌生物除草剂,特别是那些来自假单胞菌和黄单胞菌,和真菌生物除草剂,如链格孢属,炭疽病,木霉和Phoma,显示出巨大的潜力。然而,限制,例如其有限的作用范围,他们对环境的坚持,和监管问题限制了它们的商业可用性。无细胞微生物代谢物的利用由于其更简单的处理和应用而被认为是有前途的解决方案。此外,现代技术,包括与化学除草剂的封装和综合管理,进行了研究,以提高生物除草剂的功效和可持续性。
    Weeds cause significant agricultural losses worldwide, and herbicides have traditionally been the main solution to this problem. However, the extensive use of herbicides has led to multiple cases of weed resistance, which could generate an increase in the application concentration and consequently a higher persistence in the environment, hindering natural degradation processes. Consequently, more environmentally friendly alternatives, such as microbial bioherbicides, have been sought. Although these bioherbicides are promising, their efficacy remains a challenge, as evidenced by their limited commercial and industrial production. This article reviews the current status of microbial-based bioherbicides and highlights the potential of cell-free metabolites to improve their efficacy and commercial attractiveness. Stirred tank bioreactors are identified as the most widely used for production-scale submerged fermentation. In addition, the use of alternative carbon and nitrogen sources, such as industrial waste, supports the circular economy. Furthermore, this article discusses the optimization of downstream processes using bioprospecting and in silico technologies to identify target metabolites, which leads to more precise and efficient production strategies. Bacterial bioherbicides, particularly those derived from Pseudomonas and Xanthomonas, and fungal bioherbicides from genera such as Alternaria, Colletotrichum, Trichoderma and Phoma, show significant potential. Nevertheless, limitations such as their restricted range of action, their persistence in the environment, and regulatory issues restrict their commercial availability. The utilization of cell-free microbial metabolites is proposed as a promising solution due to their simpler handling and application. In addition, modern technologies, including encapsulation and integrated management with chemical herbicides, are investigated to enhance the efficacy and sustainability of bioherbicides.

    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.

    通过血脑屏障(BBB)的药物递送是现代医学时代的关键挑战之一,这是由于BBB的高度半透性特征限制了各种药物进入中枢神经系统(CNS)以管理脑部疾病。药物可以很容易地掺入到可以穿过血脑屏障的碳纳米载体中。已经开发了许多纳米载体,包括聚合物纳米颗粒,碳纳米颗粒,基于脂质的纳米颗粒,等。其中,碳纳米结构由于其更容易的BBB渗透和强的生物相容性而可能是优异的。几种CD(碳点)和CD-配体缀合物已经探索了有效地穿透BBB,这使得在使用基于CD的药物递送系统(DDS)来管理CNS疾病方面取得了重大进展。尽管有药物输送应用,它们也可以用作中枢神经系统(CNS)药物;很少有碳纳米结构显示出深刻的神经退行性活动。Further,它们对神经元生长和抗淀粉样蛋白作用的影响非常有趣。本研究涵盖了用于脑靶向药物递送的各种碳纳米结构,探索各种中枢神经系统活动。此外,它强调了最近关于中枢神经系统疾病的碳纳米结构的专利。
    Drug delivery through the blood-brain barrier (BBB) is one of the key challenges in the modern era of medicine due to the highly semipermeable characteristics of BBB that restrict the entry of various drugs into the central nervous system (CNS) for the management of brain disorders. Drugs can be easily incorporated into carbon nanocarriers that can cross the bloodbrain barrier. Numerous nanocarriers have been developed, including polymeric nanoparticles, carbon nanoparticles, lipid-based nanoparticles, etc. Among these, carbon nanostructures could be superior due to their easier BBB penetration and strong biocompatibility. Several CDs (Carbon dots) and CD-ligand conjugates have explored effectively penetrating the BBB, which enables significant progress in using CD-based drug delivery systems (DDS) to manage CNS diseases. Despite the drug delivery applications, they might also be used as a central nervous system (CNS) drug; few of the carbon nanostructures show profound neurodegenerative activity. Further, their impact on neuronal growth and anti- amyloid action is quite interesting. The present study covers diverse carbon nanostructures for brain-targeted drug delivery, exploring a variety of CNS activities. Moreover, it emphasizes recent patents on carbon nanostructures for CNS disorders.
