    This paper presents new evidence on knowledge flows in the Beijing-Tianjin-Hebei region of China, involving 43 cities (districts) in the Beijing-Tianjin-Hebei region, based on the invention patent transfer data from the State Intellectual Property Office of China. First, the characteristics of technology flows in the Beijing-Tianjin-Hebei region are analyzed in terms of changes in the number of flows, types of flowing subjects and spatial distribution characteristics. Then, a multi-level patent technology flow network in the Beijing-Tianjin-Hebei region was constructed, and the structural characteristics and node characteristics of each level network were explored separately. The key findings of the study are as follows. (1) The number of patented technology flows has been growing over time, showing obvious phase characteristics during the study period. As a whole, the intra-city (district) technology flow in the Beijing-Tianjin-Hebei region is higher than the inter-city (district). (2) The multi-level patent technology flow network in the Beijing-Tianjin-Hebei region shows dynamic characteristics, with more and more mobile subjects participating in the patent technology flow network, some network nodes becoming closer to each other, and the trend of small group technology flow increasing significantly. (3) Enterprises are the core hub of the patent technology flow network in Beijing-Tianjin-Hebei region. Individual invention patent technology transfer also occupies a high proportion and the participation of universities and colleges in the patent technology flow network in the Beijing-Tianjin-Hebei region is gradually increasing. (4) Over time, the flow of patent technology in the 43 cities (districts) in the Beijing-Tianjin-Hebei region has gradually become active and no longer relies excessively on a particular city (district) for patent technology transfer.

    几乎在每个国家,专利被授予后需要多次更新。专利权人评估专利的价值,然后支付续展费,使其在另一个规定的期限内保持有效。表征专利价值的因素是主观的。本文旨在解决建立准确模型来预测印度专利的更新寿命(通常被认为是专利价值的替代品)的研究空白,并确定影响更新寿命的重要因素。这项研究使用了从印度专利局收集的广泛数据集,用于1995年至2005年之间提交的所有授权专利。流行的统计和机器学习算法不能产生准确的预测模型,因为专利更新寿命分布(至少对于印度专利)在两个极端值处显示出不寻常的峰值,这使得建模任务更具挑战性。我们通过结合有效的多类分类器和二项回归模型来预测复杂的更新数据分布,提出了一种新的两阶段混合模型。我们将所提出的模型与几种最先进的机器学习和统计模型进行了比较分析。结果表明,与最佳竞争对手仅提供40%的准确性相比,所提出的混合模型提供了90%的准确性。
    In almost every country, patents need to be renewed multiple times after they are granted. A patentee assesses the value of the patent and then pays a renewal fee to keep it active for another stipulated period. The factors that characterize the value of a patent is subjective. This paper aims to address the research gap of building an accurate model for predicting the renewal life (often considered as a substitute for the patent value) of Indian patents, and identification of significant factors that influence the renewal life. This study uses an extensive data set collected from the Indian Patent Office for all granted patents filed between 1995 and 2005. The popular statistical and machine learning algorithms do not result in accurate predictive models, because the patent renewal life distribution (at least for the Indian patents) shows unusual spikes at the two extreme values, which makes the modeling task more challenging. We propose a new two-stage hybrid model by combining an efficient multi-class classifier and a binomial regression model for predicting the complex renewal data distribution. We conducted a comparative analysis of the proposed model with several state-of-the-art machine learning and statistical models. The results show that the proposed hybrid model gives 90% accuracy as compared to the best competitor which gives only 40% accuracy.

    组蛋白脱乙酰酶(HDAC)是一类锌依赖性酶。它们维持乙酰化稳态,具有许多生物学功能,并与许多疾病有关。HDAC3严格需要多亚基复合物形成以获得活性。它与许多非传染性疾病的进展有关。它在疾病中的广泛参与使其成为表观遗传药物靶标。先前存在的HDAC3抑制剂有许多用途,强调需要继续研究发现HDAC3选择性抑制剂。
    这篇综述概述了2010-2023年发布的24项专利,重点是抑制HDAC3同工酶的化合物。
    HDAC3选择性抑制剂-作为单一或联合疗法的药物应用至关重要-作为摆脱充满并发症的泛HDAC抑制剂的策略,正在获得牵引力。此外,对于具有替代锌结合基团(ZBG)的HDAC3抑制剂存在未满足的需求,因为一些先前存在的ZBG具有与毒性和副作用相关的局限性.实现HDAC3选择性的困难可能是由于同种型选择性。然而,计算机辅助药物设计和HDAC33D共结晶模型的实验数据的进步可能导致发现新型HDAC3选择性抑制剂。具有对HDAC3的选择性和效力平衡的替代ZBG。
    UNASSIGNED: Histone deacetylases (HDACs) are a class of zinc-dependent enzymes. They maintain acetylation homeostasis, with numerous biological functions and are associated with many diseases. HDAC3 strictly requires multi-subunit complex formation for activity. It is associated with the progression of numerous non-communicable diseases. Its widespread involvement in diseases makes it an epigenetic drug target. Preexisting HDAC3 inhibitors have many uses, highlighting the need for continued research in the discovery of HDAC3-selective inhibitors.
    UNASSIGNED: This review provides an overview of 24 patents published from 2010 to 2023, focusing on compounds that inhibit the HDAC3 isoenzyme.
    UNASSIGNED: HDAC3-selective inhibitors - pivotal for pharmacological applications, as single or combination therapies - are gaining traction as a strategy to move away from complications laden pan-HDAC inhibitors. Moreover, there is an unmet need for HDAC3 inhibitors with alternative zinc-binding groups (ZBGs) because some preexisting ZBGs have limitations related to toxicity and side effects. Difficulties in achieving HDAC3 selectivity may be due to isoform selectivity. However, advancements in computer-aided drug design and experimental data of HDAC3 3D co-crystallized models could lead to the discovery of novel HDAC3-selective inhibitors, which bear alternative ZBGs with balanced selectivity for HDAC3 and potency.

    厄洛替尼(ELB)是一种酪氨酸激酶抑制剂,靶向健康细胞和癌细胞中发现的表皮生长因子受体(EGFR)蛋白的活性。它可逆地结合EGFR酪氨酸激酶的ATP结合位点。ELB于2004年被美国食品和药物管理局(FDA)批准用于至少一种其他疗法后复发的患者的晚期非小细胞肺癌(NSCLC)治疗。它于2005年被授权与吉西他滨一起用于治疗晚期胰腺癌。除了肺癌,ELB在其他癌症的治疗中显示出有希望的结果,包括乳房,前列腺,结肠,胰腺,子宫颈,卵巢,头颈癌.然而,其有限的水溶性,作为BCSII类药物,提出了生物制药问题。已经开发了纳米配方来克服这些问题,包括增加溶解度,控释,增强稳定性,肿瘤积聚,降低毒性,克服耐药性。在老年患者中,ELB管理应涉及根据年龄相关的药物代谢变化和密切监测不良反应的个体化给药。定期评估肾功能和肝功能至关重要。本文综述了ELB在治疗各种癌症中的作用。其相关的生物制药问题,以及与ELB相关的纳米技术干预措施的最新进展。它还涵盖了前几年授予的ELB专利和正在进行的临床试验。
    Erlotinib (ELB) is a tyrosine kinase inhibitor that targets the activity of Epidermal Growth Factor Receptor (EGFR) protein found in both healthy and cancerous cells. It binds reversibly to the ATP-binding site of the EGFR tyrosine kinase. ELB was approved by the US Food and Drug Administration (FDA) in 2004 for advanced non-small cell lung cancer (NSCLC) treatment in patients who relapsed after at least one other therapy. It was authorized for use with gemcitabine in 2005 for the treatment of advanced pancreatic cancer. In addition to lung cancer, ELB has shown promising results in the treatment of other cancers, including breast, prostate, colon, pancreatic, cervical, ovarian, and head and neck cancers. However, its limited water solubility, as a BCS class II drug, presents biopharmaceutical problems. Nanoformulations have been developed to overcome these issues, including increased solubility, controlled release, enhanced stability, tumor accumulation, reduced toxicity, and overcoming drug resistance. In older patients, ELB management should involve individualized dosing based on age-related changes in drug metabolism and close monitoring for adverse effects. Regular assessments of renal and hepatic functions are essential. This review provides an overview of ELB\'s role of ELB in treating various cancers, its associated biopharmaceutical issues, and the latest developments in ELB-related nanotechnology interventions. It also covers ELB patents granted in previous years and the ongoing clinical trials.

    学术自由是科学的重要规范。尽管人们普遍认为学术自由的重要性,文献证明了对该主题的研究不足。具体来说,我们对学术自由与社会进步指标的关系知之甚少,比如创新。我们通过在1900-2015年期间使用157个国家的综合样本,实证评估学术自由对创新产出的数量(专利申请)和质量(专利引用)的影响来解决这一研究差距。我们发现,将学术自由提高一个标准差会使专利申请增加41%,向前引用增加29%。结果在一系列不同的规格中是稳健的。我们的发现对政策制定者来说是一个令人震惊的请求:过去十年来,全球学术自由度在上个世纪首次下降,我们的估计表明,这种下降对国家的创新产出构成了巨大威胁。
    Academic freedom is a critical norm of science. Despite the widely postulated importance of academic freedom, the literature attests to a dearth of research on the topic. Specifically, we know little about how academic freedom relates to indicators of societal progress, such as innovation. We address this research gap by empirically assessing the impact of academic freedom on the quantity (patent applications) and quality (patent citations) of innovation output using a comprehensive sample of 157 countries over the 1900-2015 period. We find that improving academic freedom by one standard deviation increases patent applications by 41% and forward citations by 29%. The results are robust across a range of different specifications. Our findings constitute an alarming plea to policymakers: global academic freedom has declined over the past decade for the first time in the last century and our estimates suggest that this decline poses a substantial threat to the innovation output of countries in terms of both quantity and quality.
