    对医学科学的掌握,药房,在安达卢西亚科学家的记录中可以看到植物学。这项描述性分析研究介绍了公元10世纪和11世纪的一位科学家。医学知识及其附属机构取自古代文明的医学遗产。安达卢西亚的科学家通过采用新的农业方法改变了安达卢西亚的农业和经济状况,特别是灌溉和种植药用植物。伊本·瓦菲德的名字在安达卢西亚学者中闪耀。他是中世纪药理学领域的理论家之一。他治疗病人的实用方法非常出色。他的疗法倾向于使用营养方法而不是开药。他更喜欢单一药物而不是复合药物。他坚持通过在矿泉中进行水疗治疗来治愈疾病。在植物学工作时,IbnWāfid还专门从事医学和药学。在使用Galen的作品时,他还受益于他的大师Zahrāwi的经验,亚里士多德,和Dioscorides。他的荣誉之一是为当时的国王建立了几个植物园。伊本·瓦菲德试图繁荣药理学,植物学,和医学可以被认为是对中世纪安达卢西亚这些科学的知名度的重大贡献。
    The mastery of medical sciences, pharmacy, and botany can be seen in the records of Andalusian scientists. This descriptive-analytical research introduces one of the scientists of the 10th and 11th centuries AD. Medical knowledge and its affiliates are taken from the medical heritage of ancient civilizations. Andalusian scientists changed Andalusia\'s agricultural and economic situation by adopting new agricultural methods, especially irrigation and planting of medicinal plants. The name of Ibn Wāfid shines among Andalusian scholars. He was one of the theorists in the field of pharmacology in the Middle Ages. His practical method of treating patients is remarkable. His therapies tend to use nutritional methods more than prescribing drugs. He preferred single medications to compound ones. He insisted on curing diseases through hydrotherapy in mineral springs. While working in botany, Ibn Wāfid also specialized in medicine and pharmacy. He also benefits from the experiences of his master Zahrāwi while using the works of Galen, Aristotle, and Dioscorides. One of his honours was the establishment of several botanical gardens for the kings of the time. Ibn Wāfid\'s attempt at the flourishing of pharmacology, botany, and medicine can be considered a significant contribution to the visibility of these sciences in Medieval Andalusia.

    背景:NOTOPTERYGIIRHIZOMAETRADIX(NRR),中药(TCM),已经在中国使用了几千年。在寒冷气候的高海拔地区蓬勃发展,野生NRR因其巨大的经济价值而被大量开发,尤其是在医疗领域。
    目的:本文对植物学,传统用途,植物化学,分析方法,质量控制,处理方法,药理作用,和NRR的药代动力学。这些发现为未来的研究工作提供了宝贵的见解,并为NRR的明智临床利用奠定了坚实的基础。
    方法:NRR的相关信息来自科学数据库(例如百度学者,CNKI,谷歌学者,PubMed,科学直接,WebofScience,SciFinder学者,中国草药经典,中国药典,博士和MSC学位论文,等。).
    结果:目前,从NRR中分离出的成分被鉴定为香豆素,挥发油,有机酸,黄酮类化合物,糖苷,聚乙炔,和微量元素。使用HPLC和GC技术分析大多数化合物。NRR表现出广泛的药理作用,如抗炎,镇痛药,退烧药,抗肿瘤,抗病毒,抗菌,免疫抑制活动,以及促进血液循环,祛瘀,提供神经保护,和肝脏保护。
    结论:NRR在植物化学和药理学方面的研究取得了很大进展,一些传统用途已经被现代药理学证明。然而,由于NRR的复杂化学成分尚未与其药理作用有效相关,其作用机制尚未明确阐述。在这次审查中,总结了NRR的处理方法,并提出了进一步加强NRR处理机制的探索,为NRR的临床应用提供了一定的理论帮助。此外,NRR复杂的化学成分使质量控制变得困难,因此,我们必须深入研究其质量控制。为了更好地开发和利用NRR,我们应该建立一个合理的,可靠,和准确的质量控制标准,并重点研究其活性成分与药效学指标的关系及其药理作用机制。
    BACKGROUND: NOTOPTERYGII RHIZOMA ET RADIX (NRR), a traditional Chinese medicine (TCM), has been utilized in China for millennia. Thriving in high-altitude regions with cold climates, wild NRR has been heavily exploited for its significant economic worth, particularly in the medical sector.
    OBJECTIVE: This paper presents a comprehensive review of the botany, traditional uses, phytochemistry, analytical methods, quality control, processing methods, pharmacological effects, and pharmacokinetics of NRR. These findings offer valuable insights for future research endeavors and establish a solid groundwork for the judicious clinical utilization of NRR.
    METHODS: The related information for NRR comes from scientific databases (such as Baidu Scholar, CNKI, Google Scholar, PubMed, Science Direct, Web of Science, SciFinder Scholar, Chinese Herb Classics, Chinese Pharmacopoeia, PhD and MSC Dissertations, etc.).
    RESULTS: Currently, components isolated from NRR are identified as coumarins, volatile oils, organic acids, flavonoids, glycosides, polyacetylenes, and trace elements. Most compounds are analyzed using HPLC and GC techniques. NRR exhibits a broad spectrum of pharmacological effects, such as anti-inflammatory, analgesic, antipyretic, antitumor, antiviral, antibacterial, immunosuppressive activities, as well as promoting blood circulation, removing blood stasis, providing neuroprotection, and liver protection.
    CONCLUSIONS: The research on NRR in phytochemistry and pharmacology has made great progress, and some traditional uses have been proven by modern pharmacology. However, because the complex chemical composition of NRR has not been effectively related to its pharmacological action, its mechanism of action has not been clearly expounded. In this review, the processing methods of NRR are summarized, and the exploration of further strengthening the processing mechanism of NRR is put forward, which provides some theoretical help for the clinical application of NRR. Furthermore, the complex chemical composition of NRR makes quality control difficult, so we must study its quality control thoroughly. In order to better develop and utilize NRR, we should establish a reasonable, reliable, and accurate quality control standard, and focus on the relationship between its active components and pharmacodynamic indicators and the study of its mechanism of pharmacological effects.

    主要使用动物/植物模型和单细胞藻类研究了细胞周期基因的保守真核功能。红色(红藻)海藻中的细胞周期进程及其调节成分知之甚少。我们分析了昼夜基因表达数据,以研究红海藻Gracilariopsis腱索的细胞周期。我们确定了G.chorda中的细胞周期进程和转变,这是通过关键调节因子如E2F/DP的相互作用诱导的。RBR,细胞周期蛋白依赖性激酶,和从黄昏到黎明的细胞周期蛋白。然而,几种典型的CDK抑制剂蛋白在红海藻中不存在。有趣的是,G.脊索的G1-S转换受GINS亚基3的延迟转录控制。我们认为,这种海藻中延迟的S期进入可能已经进化到将DNA损伤降至最低(例如,由于紫外线辐射)在复制过程中。我们的结果为红海藻中细胞周期相关的生理学及其分子机制提供了重要的见解。
    The conserved eukaryotic functions of cell cycle genes have primarily been studied using animal/plant models and unicellular algae. Cell cycle progression and its regulatory components in red (Rhodophyta) seaweeds are poorly understood. We analyzed diurnal gene expression data to investigate the cell cycle in the red seaweed Gracilariopsis chorda. We identified cell cycle progression and transitions in G. chorda which are induced by interactions of key regulators such as E2F/DP, RBR, cyclin-dependent kinases, and cyclins from dusk to dawn. However, several typical CDK inhibitor proteins are absent in red seaweeds. Interestingly, the G1-S transition in G. chorda is controlled by delayed transcription of GINS subunit 3. We propose that the delayed S phase entry in this seaweed may have evolved to minimize DNA damage (e.g., due to UV radiation) during replication. Our results provide important insights into cell cycle-associated physiology and its molecular mechanisms in red seaweeds.

    BACKGROUND: Labisia pumila (Blume) Fern.-Vill, also known as Kacip Fatimah, is a traditional medicinal herb common throughout Southeast Asia. It is primarily used to facilitate childbirth and postpartum recovery in women. Additionally, it can also be used to treat dysentery, rheumatism, gonorrhea, and as an anti-flatulent.
    OBJECTIVE: This article aims to provide a comprehensive review of the traditional uses, botany, cultivation, phytochemistry, pharmacological effects, practical applications, and potential uses of L. pumila (LP). Furthermore, we also explore the safety of this plant and its potential prospects for application.
    METHODS: The keywords \"Labisia pumila,\" \"Kacip Fatimah,\" and \"Marantodes pumilum\" were used to collect relevant information through electronic searches (including Elsevier, PubMed, Google Scholar, Baidu Scholar, CNKI, ScienceDirect, and Web of Science).
    RESULTS: This review summarizes 102 chemical components from different parts of the plant, including flavonoids, phenolic acids, saponins, and other chemical components. In addition, we also address the associated cultivation conditions, traditional uses, pharmacological effects and toxicity. A large number of reports indicate that LP has various pharmacological effects such as antioxidant, phytoestrogenic, anti-inflammtory, antimicrobial, anti-osteoporosis and anti-obesity properties. These results provide valuable references for future research on LP. In addition, LP is also a potential medicinal and edible plant, and is currently sold on the market as a dietary supplement.
    CONCLUSIONS: LP is a renowned traditional ethnic medicine with numerous pharmacological activities attributed to its bioactive components. Therefore, isolation and identification of the chemical components in LP can be a focus of our future research. Current studies have focused only on the effects of LP on estrogen deficiency-related diseases in women and bone diseases. There is no scientific evidence for other traditional uses. Therefore, it is important to further explore its pharmacological activities and fill the research gaps related to other traditional uses. Furthermore, research on its safety should be expanded to prepare clinical applications.

    生长素通过生长素反应因子(ARF)基因家族转录因子调节植物生长发育。ARF7是结合DNA并引发下游转录应答的五种激活剂之一。在根中,ARF7调节生长,重向性和多余的ARF19,侧根器官发生。在这项研究中,我们分析了ARF7顺式调节,使用ARF7基因座的不同非编码序列驱动GFP。我们表明,包含第一个内含子的构建体导致根尖信号增加。尽管生物信息学分析预测了第一个内含子中的几个转录因子结合位点,我们无法通过突变这些来显著改变根中GFP的表达。相反,我们观察到内含子序列需要存在于转录序列内以驱动根分生组织中的表达。这些数据支持内含子介导的增强调节根分生组织中ARF7的组织特异性表达的机制。
    Auxin regulates plant growth and development through the transcription factors of the AUXIN RESPONSE FACTOR (ARF) gene family. ARF7 is one of five activators that bind DNA and elicit downstream transcriptional responses. In roots, ARF7 regulates growth, gravitropism and redundantly with ARF19, lateral root organogenesis. In this study we analyzed ARF7 cis-regulation, using different non-coding sequences of the ARF7 locus to drive GFP. We show that constructs containing the first intron led to increased signal in the root tip. Although bioinformatics analyses predicted several transcription factor binding sites in the first intron, we were unable to significantly alter expression of GFP in the root by mutating these. We instead observed the intronic sequences needed to be present within the transcribed sequences to drive expression in the root meristem. These data support a mechanism by which intron-mediated enhancement regulates the tissue specific expression of ARF7 in the root meristem.
