Researchers from a variety of disciplines are investigating the use of extracellular vesicles (EVs) as delivery vehicles for pharmaceutical solutions. In order to make the most of the therapeutic potential of EVs, various loading strategies have been devised. Despite the widespread application of exogenous methods, endogenous approaches are becoming increasingly preferred instead. Medicinal macro molecules such as proteins and nucleic acids can be loaded with relative ease using this technology that manipulates parental cells through genetic engineering. We examine the most effective ways for EV loading and demonstrate why endogenous is superior. Extracellular vesicles (EVs), which are able to transport pharmaceuticals, have the potential to tackle the problems of biologic therapeutic stability and off-target undesirable effects. In addition, we investigate the most recent findings and applications of this innovative method in order to shed light on the numerous potential therapeutic possibilities in the field of EV-based treatments. The possibility of endogenous loading of EVs with big biological medicines has been brought to light by recent research. In order to optimize the loading of biologic drugs in extracellular vesicles (EVs), researchers have been able to apply cargo selection and loading pathway molecules thanks to advancements in EV biogenesis. It has been established that endogenous EV loading is successful in preclinical in vivo trials, which demonstrates its promise in a variety of therapeutic situations.
来自不同学科的研究人员正在研究如何利用细胞外囊泡 (EVs) 作为药液的输送载体。为了充分利用细胞外囊泡的治疗潜力,人们设计了各种装载策略。尽管外源性方法得到了广泛应用,但内源性方法却越来越受到青睐。利用这种通过基因工程操纵母细胞的技术,可以相对容易地装载蛋白质和核酸等药用大分子。我们研究了装载细胞外囊泡的最有效方法,并说明了为什么内源性技术更胜一筹。细胞外囊泡 (EV) 能够运输药物,具有解决生物治疗稳定性和脱靶不良反应问题的潜力。此外,我们还调查了这一创新方法的最新发现和应用,以揭示基于 EV 的治疗领域的众多潜在治疗可能性。最近的研究发现,EVs 可内源性负载大型生物药物。为了优化细胞外囊泡(EVs)中生物药物的负载,研究人员已经能够应用货物选择和负载路径分子,这要归功于 EV 生物发生的进步。在临床前的体内试验中,内源性 EV 负载已被证实是成功的,这证明了它在各种治疗情况下的应用前景。

This study is aimed to put light on the effect of vitamin D3 (VitD3) in newly diagnosed acute myeloid leukemia (AML) patients. The AML patients consisted of sixty patients (30 male, 30 female). The average age of patients was (36.44±8.44) years (range 25-45). Thirty healthy subjects were considered as controls (15 male and 15 female), and the average age of control group was (32.22±5.13) years. All subjects had to go through clinical examination to determine existence of other diseases in addition to evaluate some tests as complete blood count [hemoglobin (Hb), platelet (PLT), and white blood cells (WBCs)], ferritin, FBS (fasting blood sugar), TG (triglycerides), TC (total cholesterol), and HDL (high density lipoprotein cholesterol) (HDL-Ch), urea, and creatinine. Vitamin D3 was measured by minividase Biomerux/French. The VitD3 was highly significantly lower in AML patients than in controls (p=0.001). While, VitD3 was lower in male than in female AML patients but the difference was not statistically significant. There were statistically significant positive correlations between VitD3 and Hb, PLT, Wbc, ferritin, FBS, and TG in both male and female AML patients. These findings suggest that lower serum concentrations of vitamin D3 may possibly be considered as a potential factor for early assessment of acute myeloid leukemia.
本研究旨在阐明维生素 D3(VitD3)对新诊断的急性髓性白血病(AML)患者的影响。急性髓性白血病患者共 60 人(男性 30 人,女性 30 人)。患者的平均年龄为(36.44±8.44)岁(25-45 岁)。对照组为 30 名健康受试者(男 15 名,女 15 名),平均年龄为(32.22±5.13)岁。所有受试者均需接受临床检查,以确定是否患有其他疾病,此外还需评估全血细胞计数[血红蛋白(Hb)、血小板(PLT)和白细胞(WBCs)]、铁蛋白、空腹血糖(FBS)、甘油三酯(TG)、总胆固醇(TC)和高密度脂蛋白胆固醇(HDL-Ch)、尿素和肌酐。维生素 D3 由 minividase Biomerux/French 检测。急性髓细胞性白血病患者的维生素 D3 明显低于对照组(P=0.001)。男性急性髓细胞性白血病患者的维生素 D3 低于女性,但差异无统计学意义。男性和女性急性髓细胞白血病患者的 VitD3 与血红蛋白、血小板、白细胞、铁蛋白、血脂和总胆固醇之间存在统计学意义上的正相关。这些研究结果表明,血清中维生素 D3 浓度较低可能会被视为早期评估急性髓性白血病的一个潜在因素。

The skin serves as the primary barrier protecting the body from external insults, and its integrity is crucial for overall health. Formulation excipients, including emulsifiers, thickeners, and preservatives, commonly used in skincare products, can significantly influence skin barrier function and permeability. This review evaluates the impact of these Excipients on skin barrier function using biophysical measurements such as Trans-epidermal Water Loss (TEWL), skin hydration, and trans-epidermal water content. Furthermore, it discusses the potential implications of excipient-induced alterations in skin barrier function for skin health and tolerability.
皮肤是保护人体免受外界伤害的主要屏障,其完整性对人体整体健康至关重要。护肤品中常用的配方辅料(包括乳化剂、增稠剂和防腐剂)会显著影响皮肤屏障功能和渗透性。本综述通过跨表皮失水(TEWL)、皮肤水合作用和跨表皮含水量等生物物理测量方法,评估了这些辅料对皮肤屏障功能的影响。此外,报告还讨论了辅料引起的皮肤屏障功能变化对皮肤健康和耐受性的潜在影响。

Prospective role of Donanemab and amyloid beta therapies in early Alzheimer’s disease: A systematic review 多奈单抗和淀粉样蛋白β疗法在早期阿尔茨海默病中的前瞻性作用:系统综述
Pub Date : 2024-03-15 DOI: 10.18231/j.ijpca.2024.004

Amyloid-β (Aβ) peptide accumulation in the brain, leading to amyloid plaques, is considered to be the starting point of Alzheimer's disease. It is believed that these plaques impair cognitive and functional capacities and induce neurodegeneration. Research on uncommon genetic variants that either increase or decrease the quantity of Aβ deposited offers proof that amyloid plaques are involved in the disease's progression. Early-stage amyloid plaque buildup increases the likelihood that moderate cognitive impairment may progress to dementia.Donanemab, a humanized IgG1 antibody, targets an N-terminal pyroglutamate Aβ epitope that is unique to plaques that have already begun to develop. It is specific to this epitope and has no known clinical effect. Furthermore, it doesn't show any off-target binding to neurotransmitters, their receptors, or other Aβ species. In this systematic review, we first collect the necessary information after carefully reviewing four different study articles. After the data is collected, we evaluate it and create a graph to compare those study articles.
淀粉样蛋白-β(Aβ)肽在大脑中积聚形成淀粉样蛋白斑块,被认为是阿尔茨海默病的起始点。据认为,这些斑块会损害认知和功能能力,诱发神经变性。对增加或减少 Aβ 沉积量的不常见基因变异的研究证明,淀粉样蛋白斑块与疾病的进展有关。早期淀粉样蛋白斑块的堆积会增加中度认知障碍发展为痴呆症的可能性。Donanemab是一种人源化IgG1抗体,它的靶点是N端焦谷氨酸Aβ表位,这是已经开始形成的斑块所独有的。该抗体对这一表位具有特异性,而且没有已知的临床效果。此外,它不会与神经递质、其受体或其他 Aβ 物种发生任何脱靶结合。在这篇系统性综述中,我们首先仔细查阅了四篇不同的研究文章,收集了必要的信息。收集数据后,我们对其进行评估,并绘制图表对这些研究文章进行比较。

Early-stage amyloid plaque buildup increases the likelihood that moderate cognitive impairment may progress to dementia.Donanemab, a humanized IgG1 antibody, targets an N-terminal pyroglutamate Aβ epitope that is unique to plaques that have already begun to develop. It is specific to this epitope and has no known clinical effect. Furthermore, it doesn't show any off-target binding to neurotransmitters, their receptors, or other Aβ species. In this systematic review, we first collect the necessary information after carefully reviewing four different study articles. After the data is collected, we evaluate it and create a graph to compare those study articles.","PeriodicalId":14182,"journal":{"name":"International Journal of Pharmaceutical Chemistry and Analysis","volume":" 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lip care product which we use for everyday purpose contain harmful metals and preservatives. Other than absorbing through the pores on your lips, these harmful chemicals and metals can lead to heart and brain diseases. Butylated compounds are generally used as preservatives in lip balm which can lead to cancer. Which are harmful to lips. Herbal lip balms are commonly used to avoid the problem which arise due to synthetic lip balm. Herbal lip balm is applied on the lips to prevent drying and protect us against the adverse environment. Herbal lip balm protects the lips from drying, chapping, inflammation, sores, cheilitis etc. these side effects can be reduced by using the medicated lip balms. These review article provide us a treatment for lips in the formulation of medicated lip balm. All ingredient used in the formulation are totally herbal and can reduce the chances of having lip disease.
我们日常使用的唇部护理产品含有有害金属和防腐剂。这些有害化学物质和金属除了会被嘴唇上的毛孔吸收外,还会导致心脏和脑部疾病。丁基化合物通常被用作润唇膏的防腐剂,可导致癌症。对嘴唇有害。为了避免合成润唇膏带来的问题,人们通常使用草本润唇膏。草本润唇膏涂在嘴唇上可以防止干燥,保护我们免受不利环境的影响。草本润唇膏能保护嘴唇免受干燥、干裂、炎症、溃疡、唇炎等的伤害。这些评论文章为我们提供了一种治疗嘴唇的药用润唇膏配方。配方中使用的所有成分均为草本,可减少唇部疾病的发生几率。

Approximately 80% of deaths attributable to skin cancer are attributed to melanoma. The main reason for its life-threatening nature is its high tendency to metastasis. The outlook for melanoma patients with distal metastases is grim, as they have a median survival of only six months, despite the utilization of the most advanced treatments now available. The Extracellular signal-regulated kinase (ERK) pathway is the most frequently altered oncogene in melanoma. Phytochemicals are receiving significant recognition due to their minimal toxicity, affordable price, and widespread acceptance as dietary supplements. Preclinical investigations have revealed many cellular and molecular processes via which phytochemicals function in the prevention and treatment of metastatic melanoma.: In this study, we performed virtual screening of 464 phytoconstituents were obtained from the Naturally Occurring Plant-based Anti-cancer Compound-Activity-Target (NPACT) database to identify novel ERK inhibitors.: Virtual screening carried out prediction of drug-likeness and molecular docking studies with 2OJG, protein target related to ERK pathway.: Nine compounds achieved better docking score as compared to co-crystallized ligand. The accuracy of the docking method was checked using re-docking. Picetannol and sulfurentin were identified as potential inhibitors with docking score of -9.2 and -8.2, respectively. These two phytoconstituents also found to be non-carcinogenic which was predicted using a free webtool, Swiss ADME.: Our finding suggests that Piceatannol has promising potential to be further explored as ERK-pathway inhibitor in treatment of melanoma
在因皮肤癌而死亡的患者中,约有 80% 死于黑色素瘤。黑色素瘤危及生命的主要原因是其高度的转移倾向。远端转移的黑色素瘤患者前景黯淡,尽管采用了目前最先进的治疗方法,他们的中位生存期也只有 6 个月。细胞外信号调节激酶(ERK)通路是黑色素瘤中最常改变的癌基因。植物化学物质因其毒性小、价格低廉以及被广泛接受为膳食补充剂而备受认可。临床前研究揭示了植物化学物质在预防和治疗转移性黑色素瘤中发挥作用的许多细胞和分子过程:在这项研究中,我们对从天然存在的植物抗癌化合物-活性-靶点(NPACT)数据库中获得的 464 种植物成分进行了虚拟筛选,以确定新型 ERK 抑制剂:与共晶体配体相比,9 种化合物的对接得分更高。通过重新对接检验了对接方法的准确性。Picetannol 和 sulfurentin 被确定为潜在的抑制剂,其对接得分分别为 -9.2 和 -8.2。我们的研究结果表明,皮西他诺尔作为治疗黑色素瘤的ERK通路抑制剂具有进一步开发的潜力。
