    Cubosomes, a novel drug delivery system, have gained significant attention in recent years due to their unique self-assembled structures and enhanced drug encapsulation capabilities. They are administered by oral, ophthalmic, transdermal, and chemotherapeutic routes, to name a few. Due to their many potential benefits-which include high drug dispersal due to the cubic structure, a large surface area, a relatively simple manufacturing process, biodegradability, the capacity to encapsulate hydrophobic, hydrophilic, and amphiphilic compounds, targeted and controlled release of bioactive agents, and the biodegradability of lipids-cubosomes show enormous promise in drug nanoformulations for cancer therapeutics. The most common preparation method involves emulsifying a monoglyceride with a polymer, homogenizing, and then sonicating the mixture. Two distinct approaches to preparing are top-down and bottom-up. This evaluation will examine the materials, methods of preparation, cubosome-related drug encapsulating techniques, drug loading, release mechanism, and their uses. The following databases were used for literature searches: PubMed, Frontiers, Science Direct, Springer, Wiley, and MDPI. For the purpose of finding pertinent articles and contents (2015-2024), the keywords \"cubosome; drug delivery systems, nano-carrier, theranostic, drug release mechanism\" and others of a similar nature were utilized. This review will conduct a comprehensive analysis of the cubosome-related composition, production methods, drug encapsulating strategies, drug release mechanisms, and applications. Moreover, the difficulties encountered in fine-tuning different parameters to improve loading capabilities and prospects are also discussed. Innovation in pharmaceutical research and development can be stimulated by the knowledge gathered about cubosomal drug delivery methods. Through the clarification of the mechanisms involved in drug release from cubosomes and the investigation of innovative fabrication procedures, scientists can enhance the cubosomal formulation design for targeted therapeutic uses.

    从绿色废物中开发纳米肥料是提高全球农业生产和减少环境污染的有效选择之一。在这项研究中,小说,使用行星式球磨程序合成了环保且具有成本效益的纳米功能肥料(NEF)。NEF(nDPF1和nDPF2)是通过分别以1:1和3:1(w/w)的比例用(KH2PO4MgO)浸渍纳米结构的枣树坑(nDPP)来制备的。nDPP,nDPF1和nDPF2被广泛表征。生产的纳米肥料增强了土壤保水能力,其中nDPF2最有效。nDPF2处理土壤的保水能力是常规肥料处理土壤的5.6倍。此外,nDPF2表现出优异的持续较低的P释放速率,与常规肥料相比,钾和镁养分的释放时间更长。例如,常规肥料的P累积释放百分比,nDPF1和nDPF2在土壤中达到22.41%,384h内分别为10.82%和8.9%。FTIR和XPS分析结果表明,氢键和配体交换是PO4-K-Mg离子与nDPP表面的主要相互作用机制。NEF发布的动力学数据表明,幂函数是描述P动力学的最佳模型,水和土壤中NEF的K和Mg释放数据。盆栽研究确定,与商业肥料处理的植物相比,纳米肥料(nDPF1和nDPF2)显着促进了玉米植物的生物量生产和养分吸收。目前的工作证明了NEF增加营养素吸收效率的潜力,缓解干旱土壤中的水分滞留问题,通过淋洗减少养分流失,保护环境。
    Development of nano-enabled fertilizers from green waste is one of the effective options to enhance global agricultural productions and minimize environmental pollution. In this study, novel, eco-friendly and cost-effective nano- enabled fertilizers (NEF) were synthesized using the planetary ball milling procedure. The NEF (nDPF1and nDPF2) were prepared by impregnation of nanostructured date palm pits (nDPP) with (KH2PO4 + MgO) at 1:1 and 3:1 (w/w) ratios respectively. The nDPP, nDPF1 and nDPF2 were extensively characterized. The produced nano-fertilizers enhanced soil water retention capacity with nDPF2 being the most effective. The water retention capacity of nDPF2 treated soil was 5.6 times higher than that of soil treated with conventional fertilizers. In addition, the nDPF2 exhibited superior sustained lower release rates of P, K and Mg nutrients for longer release periods in comparison with the conventional fertilizers. For instance, P cumulative release percentages from conventional fertilizers, nDPF1 and nDPF2 in soil reached 22.41%, 10.82 and 8.9% respectively within 384 h. Findings from FTIR and XPS analyses suggested that hydrogen bonding and ligand exchange were the main interaction mechanisms of PO4-K-Mg ions with nDPP surface. The released kinetics data of the NEF revealed that power function was the best suitable model to describe the kinetics of P, K and Mg release data from NEF in water and soil. Pot study ascertained that the nano-enabled fertilizers (nDPF1 and nDPF2) significantly promoted biomass production and nutrient uptake of maize plants as compared to commercial fertilizer treated plants. The present work demonstrated the potential of NEF to increase nutrients uptake efficiency, mitigate moisture retention problem in arid soils and reduce nutrients loss through leaching and safeguard the environment.

    本研究旨在研究当归多糖(ASP)作为冬凌草甲素(ORI)本能肝靶向给药载体治疗肝细胞癌(HCC)的可行性。ASP通过酯化反应与脱氧胆酸(DOCA)反应以形成ASP-DOCA缀合物。通过薄膜水法制备了负载ORI的ASP-DOCA纳米颗粒(ORI/ASP-DOCANP),在水溶液中它们的尺寸约为195nm。ORI/ASP-DOCANP的载药量高达9.2%。ORI/ASP-DOCANP中ORI的释放是pH依赖性的,导致在酸性pH下快速分解和加速药物释放。ORI/ASP-DOCANP通过ASGPR介导的内吞作用显着增强了ORI在肝肿瘤中的积累。体外实验结果表明,ORI/ASP-DOCANPs增加HepG2细胞的摄取和凋亡,体内结果表明,与游离ORI相比,ORI/ASP-DOCANP在H22荷瘤小鼠中引起有效的肿瘤抑制。总之,ORI/ASP-DOCANP可能是一个简单的,可行,安全有效的ORI纳米给药系统,可用于肝肿瘤的靶向给药和治疗。
    The present work aimed to study the feasibility of Angelica sinensis polysaccharide (ASP) as an instinctive liver targeting drug delivery carrier for oridonin (ORI) in the treatment of hepatocellular carcinoma (HCC). ASP was reacted with deoxycholic acid (DOCA) via an esterification reaction to form an ASP-DOCA conjugate. ORI-loaded ASP-DOCA nanoparticles (ORI/ASP-DOCA NPs) were prepared by the thin-film water method, and their size was about 195 nm in aqueous solution. ORI/ASP-DOCA NPs had a drug loading capacity of up to 9.2%. The release of ORI in ORI/ASP-DOCA NPs was pH-dependent, resulting in rapid decomposition and accelerated drug release at acidic pH. ORI/ASP-DOCA NPs significantly enhanced the accumulation of ORI in liver tumors through ASGPR-mediated endocytosis. In vitro results showed that ORI/ASP-DOCA NPs increased cell uptake and apoptosis in HepG2 cells, and in vivo results showed that ORI/ASP-DOCA NPs caused effective tumor suppression in H22 tumor-bearing mice compared with free ORI. In short, ORI/ASP-DOCA NPs might be a simple, feasible, safe and effective ORI nano-drug delivery system that could be used for the targeted delivery and treatment of liver tumors.

    背景:癌症是导致死亡的主要原因,癌细胞由于长期暴露于补充化疗治疗而产生耐药性的易感性被称为多药耐药癌细胞(MDRC),这是恶性肿瘤治疗的一个重要障碍。由于补充药物失去了效力,近年来,开发潜在的替代和新颖的治疗方法已被提升为重中之重。在这种情况下,来自植物和动物来源的生物活性蛋白凝集素显示出具有巨大治疗潜力的抗癌药物的宝贵来源。
    目的:本手稿的主要目的是启发基于证据的(从1986年到2022年)使用凝集素替代治疗方法的可能分子机制,而不是用于癌症治疗的补充药物。
    方法:已适当遵循PRISMA规则,并系统地综合了定性和定量数据。文章是基于临床和临床前报告发表的凝集素,研究了深入的细胞机制,逆转药物综合肿瘤学,作为纳米携带的靶向递送。1986年至2022年对文章进行了系统筛选,并根据电子数据库搜索进行了筛选,Medline(PubMed),谷歌学者,WebofScience,百科全书,Scopus,和ClinicalTrials.gov数据库。
    结果:搜索发现了来自38个不同国家的4,212种出版物,其中170篇参考文章被用于我们的分析,在16种联合疗法及其作用方式中,包括剂量和作用机制的27项临床试验研究。纳入了属于28个不同家庭的30种凝集素的报告。根据一些临床和临床前报告,对凝集素的逆转机制和针对MDRC的替代疗法进行了严格的筛选,凝集素可以抑制过表达的基因,如P-53,EGFR,还有P-GP,MRP,和ABC转运蛋白与药物的细胞内运输有关。因为,药物外排机制导致MDRC,在这种现象中,凝集素在逆转外排机制中起关键作用。很少有临床前报道提到,凝集素与补充药物结合显示出协同作用,并且作为纳米药物载体有助于递送到靶向部位。
    结论:我们已经讨论了使用凝集素的替代疗法,并深入了解了对抗MDRC癌症的逆转耐药机制,增强功效,减少毒性和不良事件,并确保有针对性的交付,并对其在癌症诊断和预后方面的应用进行了讨论。然而,在药物开发和临床试验中需要进一步的研究,这可能有助于阐述MDRC癌症的逆转机制和开启新的治疗模式.
    BACKGROUND: Cancer is characterized as the leading cause of death, and the susceptibility of cancer cells to develop resistance due to long-term exposure to complementary chemotherapeutic treatment is referred to as multidrug resistance cancer cells (MDRC), which is a significant obstacle in the treatment of malignancies. Since complementary medicine lost its effectiveness, the development of potential alternative and novel therapeutic approaches has been elevated to a top priority in recent years. In this context, a bioactive protein lectin from plant and animal sources exhibits an invaluable source of anticancer agents with vast therapeutic potential.
    OBJECTIVE: This manuscript\'s primary purpose is to enlighten the evidence-based (from 1986 to 2022) possible molecular mechanism of alternative treatment approaches using lectins over the complementary medicines used for cancer treatment.
    METHODS: The PRISMA rules have been followed properly and qualitative and quantitative data are synthesized systematically. Articles were identified based on Clinical and preclinical reports published on lectin that investigated the in-depth cellular mechanisms, of reverse drug integrative oncology, as a nano-carried targeted delivery. Articles were systematically screened from 1986 to 2022 and selected based on electronic database searches, Medline (PubMed), Google Scholar, Web of Science, Encyclopaedias, Scopus, and ClinicalTrials.gov database.
    RESULTS: The search turned up 4,212 publications from 38 different nations, of which 170 reference articles were used in our analysis, in 16 combination therapy and their mode of action, and 27 clinical trial studies including dosage and mechanism of action were included. Reports from the 30 lectins belonging to 28 different families have been included. The reversal mechanism of lectin and alternative therapy against MDRC is critically screened and according to a few clinical and preclinical reports, lectin can suppress the overexpressing genes like P-53, EGFR, and P-gp, MRP, and ABC transporter proteins associated with intracellular transportation of drugs. Since, the drug efflux mechanism leads to MDRC, in this phenomenon, lectin plays a key role in reversing the efflux mechanism. Few preclinical reports have mentioned that lectin shows synergism in combination with complementary medicine and as a nano drug carrier helps to deliver to the targeted site.
    CONCLUSIONS: We have discussed the alternative therapy using lectin and an in-depth insight into the reversal drug resistance mechanisms to combat MDRC cancer, enhance the efficacy, reduce toxicity and adverse events, and ensure targeted delivery, and their application in the field of cancer diagnosis and prognosis has been discussed. However, further investigation is necessary in drug development and clinical trials which could be helpful to elaborate the reversal mechanism and unlock newer treatment modalities in MDRC cancer.

    脑癌是一种侵袭性类型的癌症,预后较差。虽然免疫系统在早期阶段可以预防癌症,肿瘤利用炎症反应的愈合臂加速其生长和扩散。各种免疫细胞穿透发展中的肿瘤区域,建立一个促炎的肿瘤环境.此外,肿瘤细胞可能释放趋化因子和细胞因子来吸引免疫细胞并促进癌症生长。炎症及其在癌症进展中的相关机制已在大多数实体瘤中被广泛研究,尤其是脑瘤.然而,恶性脑癌的治疗受到几个障碍的阻碍,比如血脑屏障,大脑间质内的运输,促进肿瘤生长和侵袭的炎症介质,特别是对肿瘤细胞给予治疗的并发症,胶质瘤的高侵袭性,以及对药物的抗性。为了解决这些障碍,纳米医学可能是一种潜在的策略,促进了诊断和治疗脑癌的进步。由于它们的小尺寸和其他功能提供了许多好处,纳米颗粒一直是药物递送领域的研究热点。本文的目的是讨论炎症介质和信号通路在脑癌中的作用,以及理解纳米载体方法在脑癌治疗中增强药物向脑递送的最新进展。
    Brain cancer is an aggressive type of cancer with poor prognosis. While the immune system protects against cancer in the early stages, the tumor exploits the healing arm of inflammatory reactions to accelerate its growth and spread. Various immune cells penetrate the developing tumor region, establishing a pro-inflammatory tumor milieu. Additionally, tumor cells may release chemokines and cytokines to attract immune cells and promote cancer growth. Inflammation and its associated mechanisms in the progression of cancer have been extensively studied in the majority of solid tumors, especially brain tumors. However, treatment of the malignant brain cancer is hindered by several obstacles, such as the blood-brain barrier, transportation inside the brain interstitium, inflammatory mediators that promote tumor growth and invasiveness, complications in administering therapies to tumor cells specifically, the highly invasive nature of gliomas, and the resistance to drugs. To resolve these obstacles, nanomedicine could be a potential strategy that has facilitated advancements in diagnosing and treating brain cancer. Due to the numerous benefits provided by their small size and other features, nanoparticles have been a prominent focus of research in the drug-delivery field. The purpose of this article is to discuss the role of inflammatory mediators and signaling pathways in brain cancer as well as the recent advances in understanding the nano-carrier approaches for enhancing drug delivery to the brain in the treatment of brain cancer.

    过度使用合成肥料造成经济负担,增加土壤,水和大气污染。纳米肥料在土壤肥力的可持续使用方面显示出巨大的潜力,作物生产和最小或没有环境权衡。纳米肥料是亚微观尺寸的,具有大的表面积与体积比,可以有营养封装,和更大的流动性,因此它们可以增加植物养分获取和作物产量。由于这些属性,纳米肥料被认为是可交付的“智能营养系统”。然而,农业生态系统中的问题比现有的发展更广泛。例如,土壤不同理化性质中的养分输送,水分,和其他农业生态条件仍然是一个挑战。在这种情况下,本综述概述了纳米技术在农业中的各种用途,纳米肥料优先于常规肥料,纳米颗粒的形成,移动性,以及在异质土壤中的作用,特别强调壳聚糖基纳米肥料的开发和使用。
    Excessive use of synthetic fertilizers cause economic burdens, increasing soil, water and atmospheric pollution. Nano-fertilizers have shown great potential for their sustainable uses in soil fertility, crop production and with minimum or no environmental tradeoffs. Nano-fertilizers are of submicroscopic sizes, have a large surface area to volume ratio, can have nutrient encapsulation, and greater mobility hence they may increase plant nutrient access and crop yield. Due to these properties, nano-fertilizers are regarded as deliverable \'smart system of nutrients\'. However, the problems in the agroecosystem are broader than existing developments. For example, nutrient delivery in different physicochemical properties of soils, moisture, and other agro-ecological conditions is still a challenge. In this context, the present review provides an overview of various uses of nanotechnology in agriculture, preference of nano-fertilizers over the conventional fertilizers, nano particles formation, mobility, and role in heterogeneous soils, with special emphasis on the development and use of chitosan-based nano-fertilizers.
