Luminal breast cancer cells exhibit proliferative and metastatic characteristics. Exploration of the effective treatment with minimum side effects is necessary. This study aimed to confirm the combination treatment of a potent anticancer candidate PGV-1 and hesperidin on luminal breast cancer cells, T47D, covering its cytotoxic and anti-migratory activities. PGV-1 showed much stronger cytotoxicity with an IC50 value of 2 μM than that of hesperidin (200 μM) as evaluated by trypan blue exclusion assay, but the combination of the two compounds exhibited a synergistic effect. Propidium iodide (PI) staining with flow cytometry proved that the combination treatment increased the cell population in the G2/M phase. Additionally, the combination treatment increased senescent cells as shown in senescence associated β-galactosidase (SA-β-gal) assay which might correlate to its antiproliferative properties. In addition, the scratch wound healing assay showed that the combination also inhibited cell migration significantly. Molecular docking of the two compounds demonstrated potential interaction with their protein targets in cell cycle machinery, i.e. KIF1, CDK1, TOP2A, CA12, ESR1, FN1, and TYMS. Altogether, these findings strengthen the evidence of anti-cancer properties enhancement of PGV-1 in luminal breast cancer through combining the compound with hesperidin.
腔隙性乳腺癌细胞具有增殖和转移的特点。有必要探索副作用最小的有效治疗方法。本研究旨在证实一种强效抗癌候选药物 PGV-1 和橙皮甙对管腔型乳腺癌细胞 T47D 的联合治疗,包括其细胞毒性和抗迁移活性。通过胰蓝排除法评估,PGV-1 的 IC50 值为 2 μM,比橙皮甙的 IC50 值(200 μM)强得多,显示出更强的细胞毒性。用流式细胞仪进行碘化丙啶(PI)染色证明,联合处理增加了处于 G2/M 期的细胞数量。此外,衰老相关的 β-半乳糖苷酶(SA-β-gal)检测显示,联合处理增加了衰老细胞,这可能与其抗增殖特性有关。此外,划痕伤口愈合试验表明,这两种化合物还能显著抑制细胞迁移。这两种化合物的分子对接表明,它们可能与细胞周期机制中的蛋白靶标(即 KIF1、CDK1、TOP2A、CA12、ESR1、FN1 和 TYMS)发生相互作用。总之,这些研究结果加强了 PGV-1 与橙皮甙联用对腔隙型乳腺癌抗癌作用的证据。

Lactobacillus plantarum FNCC-0461 is a lactic acid bacteria isolated from "dadih" a traditional Indonesian food that has potential as a probiotic. Probiotics can show health benefits if they can maintain cell viability of at least 7 log CFU in the distal ileum and colon. However, most probiotics are not resistant to the extreme conditions of the gastrointestinal tract. Probiotic encapsulation in the form of pectin-based colon targeted pellets is a promising delivery system to overcome probiotic viability problems due to the gastrointestinal tract extreme conditions and can assist release to specific target site in colon. Pellets was produced by extrusion-spheronization method using microcrystalline cellulose (MCC), lactose and pectin. Optimization of spheronization process was carried out by varying the spheronization speed and time while the optimization of pellets formula was carried out by varying the concentration of total pectin and the type of coating polymer (cellulose acetate phthalate (CAP) or shellac). The morphology, particle size, moisture content, micromeritic properties, process yield and viability of pellets were evaluated. Release of probiotics on coated and uncoated pellets were examined at pH 1.2, 6.8 and 7.4 under simulated colon fluid for 24 hours. The formula containing MCC, lactose and pectin (5:4:1) with spheronization speed at 1500 rpm for 15 minutes showed the best pellets characteristic and cell viability. The pellets obtained were spherical, with particle size distribution of 913.57±8.28 μm, process yield of 88.71±1.04 % and viability of 7.50 x 107 cfu/g. Pellets coated with CAP showed the highest cell release in simulated colon fluid of 1.38 x 107 CFU/g at 24 hours. This research proved that CAP coated pellet formulation has promising potential for colon targeted delivery of L. plantarum as well as to protect the viability of probiotics for colon-targeted delivery.
植物乳杆菌 FNCC-0461 是一种从印尼传统食品 "dadih "中分离出来的乳酸菌,具有作为益生菌的潜力。益生菌如果能在回肠远端和结肠中保持至少 7 log CFU 的细胞活力,就能为健康带来益处。然而,大多数益生菌都无法抵御胃肠道的极端条件。以果胶为基础的结肠靶向颗粒形式的益生菌封装是一种很有前景的给药系统,它能克服由于胃肠道极端条件造成的益生菌存活问题,并能帮助释放到结肠中的特定靶点。使用微晶纤维素(MCC)、乳糖和果胶,通过挤压-球化方法生产出颗粒。通过改变球化速度和时间来优化球化过程,而通过改变总果胶的浓度和包衣聚合物的类型(邻苯二甲酸醋酸纤维素(CAP)或虫胶)来优化颗粒配方。对颗粒的形态、粒度、含水量、微粒特性、加工产量和存活率进行了评估。在 pH 值为 1.2、6.8 和 7.4 的模拟结肠液条件下,对包衣和未包衣颗粒上益生菌的释放进行了 24 小时的检测。含有 MCC、乳糖和果胶(5:4:1)的配方以 1500 转/分钟的球化速度球化 15 分钟,显示出最佳的颗粒特性和细胞活力。获得的颗粒呈球形,粒度分布为 913.57±8.28 μm,加工产率为 88.71±1.04%,细胞存活率为 7.50 x 107 cfu/g。24 小时后,涂有 CAP 的颗粒在模拟结肠液中的细胞释放量最高,达到 1.38 x 107 CFU/g。这项研究证明,涂有 CAP 的颗粒制剂有望用于植物乳杆菌的结肠靶向给药,并保护结肠靶向给药益生菌的活力。

The genus Leea is a genus of medicinal plants. Half of this genus species are traditionally used to treat various ailments. This genus also holds promise for molecules that have the potential to be used as drugs or lead compounds in the discovery of a new drug. So far, 66 compounds have been isolated from this genus, 46 known to have pharmacological activity. Antioxidant, antimicrobial, anti-inflammatory and anticancer are the pharmacological activities most frequently found in these compounds. Although the toxicity studies are still limited to chronic toxicity tests showing low toxicity potential. The fact that various pharmacological activities and low potential make toxicity makes this plant worthy of continued study. The potential to possibility drugs from this genus is also huge.
韭菜属是一个药用植物属。该属的一半物种传统上用于治疗各种疾病。该属植物也有望发现有潜力用作药物的分子或发现新药物的先导化合物。迄今为止,已从该属植物中分离出 66 种化合物,其中 46 种已知具有药理活性。抗氧化、抗菌、抗炎和抗癌是这些化合物中最常见的药理活性。虽然毒性研究仍局限于慢性毒性试验,但显示其毒性潜力较低。各种药理活性和低潜在毒性使这种植物值得继续研究。从该属植物中提取药物的潜力也是巨大的。

Mental health disorders are currently widely discussed, especially anxiety and depression. The number of people living with anxiety and depression disorders in 2020 increased significantly due to the COVID-19 pandemic. These mental health disorders are quite serious and need to be addressed. Indonesian people for generations have used medicinal plants in everyday life, one of which is to treat symptoms of mental health disorders such as increasing mood and motivation, calming, overcoming depression, stress, anxiety, and sleep disorders. However, there has been no comprehensive review on the ethnopharmacology of Indonesian medicinal plants that can treat mental health disorders such as depression and anxiety and there is also little scientific evidence to support the efficacy of these plants. This paper reviews Indonesian medicinal plants used to treat mental health disorders and reviews the scientific evidence for these plants. We conduct literature studies of scientific articles, research journals, and books at national and international vessels. The search results identified 67 Indonesian medicinal plants used to treat symptoms of mental health disorders. The Zingiberaceae family is reported as the most medicinal plant that can potentially treat mental health disorders such as depression and anxiety. Several plants have been proven in preclinical research, but many still have not been studied and proven. Therefore, further research on Indonesian medicinal plants that can overcome mental health disorders must be carried out to provide knowledge and develop drugs for mental health disorders.
心理健康疾病,尤其是焦虑症和抑郁症,目前正被广泛讨论。由于 COVID-19 的流行,2020 年患有焦虑症和抑郁症的人数大幅增加。这些精神疾病相当严重,亟待解决。印度尼西亚人世世代代都在日常生活中使用药用植物,其中之一就是治疗精神疾病的症状,如增强情绪和动力、镇静、克服抑郁、压力、焦虑和睡眠障碍。然而,目前还没有关于印尼药用植物治疗抑郁和焦虑等精神疾病的民族药理学的全面综述,也几乎没有科学证据支持这些植物的功效。本文回顾了用于治疗精神疾病的印尼药用植物,并回顾了这些植物的科学证据。我们对国内外的科学文章、研究期刊和书籍进行了文献研究。搜索结果发现了 67 种用于治疗精神疾病症状的印尼药用植物。据报道,最有可能治疗抑郁症和焦虑症等精神疾病的药用植物是姜科植物。有几种植物已在临床前研究中得到证实,但仍有许多植物尚未得到研究和证实。因此,必须进一步研究印尼可治疗精神疾病的药用植物,以提供知识和开发治疗精神疾病的药物。

Hepatitis C virus (HCV) is an RNA virus that is easy to mutate and high risk of resistance. The vaccine for HCV has not been provided yet, and the current treatment is very expensive. To provide alternative and complementary antiviral from plants, this study evaluated the activities of Piper betle (P. betle) against HCV and its combination with existing antiviral drugs, Ribavirin and Simeprevir. The antiviral inhibition was identified by in vitro culture using Huh7it-1 cells and JFH1a HCV. Moreover, the phytochemistry profile was also determined by Thin Layer Chromatography (TLC) and High-Performance Liquid Chromatography (HPLC). The result showed that the ethanol extract of P. betle was possess strong activity with an IC50 value of 0.08 ± 0.028 µg/mL. The mechanism of action revealed the extract dominantly inhibit in the post-entry steps. Furthermore, the combination of P. betle extract with simeprevir increased its anti-HCV activity, however, no effect was observed in the combination with ribavirin. The Western blotting analysis was shown inhibition of NS3 protein levels in a dose-dependent manner. Phytochemistry evaluation was shown for the extract containing flavonoids, polyphenols, and alkaloids. These results suggested that the ethanolic extract of P. betle could be a good candidate for the development or an alternative to anti-HCV drugs. Keywords: Hepatitis C Virus, Piper betle, Medicinal plants, Simeprevir, Ribavirin, Medicine.
丙型肝炎病毒(HCV)是一种 RNA 病毒,容易发生变异,抗药性风险很高。丙型肝炎病毒的疫苗尚未问世,目前的治疗费用也非常昂贵。为了提供植物抗病毒的替代性和互补性,本研究评估了瓜蒌(P. betle)对 HCV 的活性及其与现有抗病毒药物利巴韦林(Ribavirin)和西美普韦(Simeprevir)的组合。通过使用 Huh7it-1 细胞和 JFH1a HCV 进行体外培养,确定了其抗病毒抑制作用。此外,还通过薄层色谱法(TLC)和高效液相色谱法(HPLC)测定了植物化学成分。结果表明,槟榔的乙醇提取物具有很强的活性,其 IC50 值为 0.08 ± 0.028 µg/mL。作用机制显示,槟榔乙醇提取物主要抑制后进入步骤。此外,槟榔提取物与西美瑞韦(simeprevir)合用可提高其抗 HCV 活性,但与利巴韦林合用则没有效果。Western 印迹分析表明,槟榔提取物对 NS3 蛋白水平的抑制呈剂量依赖性。植物化学评估显示,提取物中含有黄酮类、多酚类和生物碱。这些结果表明,槟榔的乙醇提取物可能是开发抗HCV药物或替代药物的良好候选物。关键词:丙型肝炎病毒丙型肝炎病毒 瓜蒌 药用植物 西美瑞韦 利巴韦林 药物

Bulbine frutescens is an indigenous succulent medicinal plant in South Africa. The plant is commonly used traditionally for the treatment of skin related ailments. B. frutescens has been reported to possess antioxidant, anti-viral and antimicrobial properties. To date, most studies have been conducted on the leaves, while limited reports have been documented on the roots, as well as comparative analyses between both plant parts. The aim of this study was to determine the phytochemical content, antioxidant and antibacterial activities in the leaves and roots of B. frutescens. Methanolic extracts of each plant part were assessed on the phytochemical analysis, antioxidant (DPPH, hydrogen peroxide, metal chelating) and antibacterial activity against S. aureus and E. coli. The results from the phytochemical screening showed that the leaves contained more phytochemical groups than the roots. The roots displayed higher total phenolics (991.7 ± 54.1 mg GAE/g), total flavonoid (285.8 ± 60.6 mg QE/g) and total tannin contents (1698.75 ± 28.15 mg GAE/g) than the leaves. The roots also showed a stronger antioxidant activity in DPPH (3.43 ± 0.16 mg/ml) and metal chelating (0.54 ± 0.01 mg/ml) assays, compared to the leaves, which only showed a higher scavenging power against hydrogen peroxide radicals (1.48 ± 0.02 mg/ml) than the roots. Both plant parts showed intermediate zones of inhibition (10-19 mm) against both bacterial strains, with the exception of the leaves which had a 20.67 ± 0.67 mm inhibition against S. aureus. These results validate the uses of both leaves and roots of B. frutescens in traditional medicine and further suggests for the application of the roots in pharmaceutical and cosmetic industries.Bulbine frutescens is an indigenous succulent medicinal plant in South Africa.

The strategy of producing PGA on a massive scale with high levels of soluble protein can be through recombinant genetic techniques and expressed in a certain host. E. coli is still a popular bacterial host to produce a recombinant protein which has advantages such as fast growth, low production cost, and high expression rate. Apart from its advantages, E. coli as a production host also has disadvantages including the expression of recombinant proteins often failing to form the proper folding conformation which makes the protein biologically inactive. Many strategies can be developed to overcome these problems, such as the selection of the host strain (E. coli HB101 & JM109), fusion protein to enhance the recovery of soluble protein (MBP & NusA), optimization of fermentation (low-temperature incubation), and optimization of the protein isolation process for the recovery of active PGA (Freeze-thawing method).
大规模生产高水平可溶性 PGA 蛋白的策略是通过基因重组技术,并在一定的宿主中进行表达。大肠杆菌仍然是生产重组蛋白的常用细菌宿主,它具有生长快、生产成本低、表达率高等优点。除了优点之外,大肠杆菌作为生产宿主也有缺点,包括表达的重组蛋白往往不能形成正确的折叠构象,从而使蛋白失去生物活性。为克服这些问题,可开发多种策略,如选择宿主菌株(大肠杆菌 HB101 和 JM109)、融合蛋白以提高可溶性蛋白的回收率(MBP 和 NusA)、优化发酵(低温培养)以及优化蛋白分离过程以回收活性 PGA(冻融法)。

Non-adherence to hypertension treatment is a wide problem, especially among senior citizens. Several approaches are needed to improve adherence, including identifying and prioritizing problems related to adherence. A formative study employing Theory of Planned Behavior (TPB) has revealed some salient beliefs underlying the intention to adhere to hypertension medication among seniors. To be the priority in a medication adherence strategy, the correlation of these beliefs on adherence needs to be further investigated. This study aims to determine which beliefs correlate most to the intention to hypertension medication adherence among seniors. A cross-sectional survey was conducted to seniors with hypertension in Yogyakarta and its surroundings. A questionnaire based on TPB was developed and utilized in this study. The questionnaire was distributed conveniently through two senior communities (offline) as well as Google Form link to some WhatsApp group of seniors (online) during September-October 2023. The data were analyzed using multiple linear regressions. Thirty-seven seniors completed the offline questionnaire, and 60 seniors completed the online questionnaire. The age of participants was 64.70 ± 7.123 years. Subjective norms and perceived behavioral control accounted significantly (p<0.001) for 59,3% of the variance in the adherence intention, but not attitude. Perceived behavioral control had the strongest correlation on intention. Participants’ beliefs of knowing how high their blood pressure was had the highest correlation to perceived behavioral control. Understanding which belief correlates most with intention to adherence provides insight to develop strategy to improve adherence among seniors.
不坚持高血压治疗是一个广泛存在的问题,尤其是在老年人中。要改善坚持治疗的情况,需要采取多种方法,包括识别与坚持治疗有关的问题并将其列为优先事项。一项运用计划行为理论(TPB)进行的形成性研究揭示了老年人坚持高血压药物治疗意愿的一些突出信念。为了成为坚持服药策略中的优先事项,需要进一步研究这些信念与坚持服药的相关性。本研究旨在确定哪些信念与老年人高血压服药意向的相关性最大。研究人员对日惹及其周边地区患有高血压的老年人进行了横断面调查。本研究采用了基于 TPB 的调查问卷。调查问卷于 2023 年 9 月至 10 月期间通过两个老年社区(线下)以及谷歌表格链接(线上)向一些老年 WhatsApp 群组发放。数据采用多元线性回归分析。37 名老年人完成了线下问卷,60 名老年人完成了线上问卷。参与者的年龄为 64.70 ± 7.123 岁。主观规范和感知到的行为控制占坚持意向变异的 59.3%,但不占态度变异的 59.3%(p<0.001)。感知行为控制与意向的相关性最强。参与者知道自己血压有多高的信念与感知行为控制的相关性最高。了解哪种信念与坚持治疗的意向关系最大,有助于制定改善老年人坚持治疗的策略。

The Influence of MTHFR C677T Variants on Neuropathy Risk Among T2dm Patients Receiving Monotherapy Metformin 接受二甲双胍单药治疗的 T2dm 患者中 MTHFR C677T 变异对神经病变风险的影响
Pub Date : 2024-03-25 DOI: 10.22146/ijp.5328

Neuropathy is the most common microvascular complication among type 2 diabetes mellitus (T2DM). Metformin consumption increases neuropathy risk. The Methylenetetrahydrofolate reductase (MTHFR) enzyme has confirmed its role in neuropathy. Metformin and MTHFR could decrease folate and induce hyperhomoscysteine. One of the common variants of the MTHFR gene is C677T and its located in the exon area. This study aimed to observe the association between variant C677T in the MTHFR gene and the risk of neuropathy among newly diagnosed T2DM patients with naive metformin. This cross-sectional study recruited 103 patients. The neuropathy risk was examined according to medical judgment through Neuropathy Symptom Score (NSS) and Neuropathy Disability Score (NDS) criteria. Genotyping C677T was performed using PCR-RFLP. This study found only one patient has a homozygote mutant, but more than 50% of patients were detected with allele mutants. There were no statistical differences in patient characteristics between CC and CT genotypes (p>0.05). Association between C677T and neuropathy risk was not significant statistically, either in the genotype model (p=0.97), allele model (p=0.82), and dominant model (p=0.91). There was still no significant association after adjusting for several confounding factors. We conclude that C677T in our population did not influence neuropathy risk. More specific criteria and laboratory parameters indicated neuropathy should be examined in the future study. Keywords: MTHFR, neuropathy, metformin, and T2DM
神经病变是 2 型糖尿病(T2DM)中最常见的微血管并发症。服用二甲双胍会增加神经病变的风险。亚甲基四氢叶酸还原酶(MTHFR)已被证实在神经病变中发挥作用。二甲双胍和 MTHFR 可减少叶酸并诱发高半胱氨酸血症。MTHFR 基因的常见变异之一是 C677T,位于外显子区域。本研究旨在观察MTHFR基因变异体C677T与二甲双胍新诊断T2DM患者神经病变风险之间的关系。这项横断面研究共招募了 103 名患者。通过神经病变症状评分(NSS)和神经病变残疾评分(NDS)标准,根据医学判断对神经病变风险进行检查。使用 PCR-RFLP 对 C677T 进行基因分型。研究发现,只有一名患者存在同型突变,但超过 50% 的患者被检测出等位基因突变。CC 和 CT 基因型的患者特征没有统计学差异(P>0.05)。无论是在基因型模型(P=0.97)、等位基因模型(P=0.82)还是显性模型(P=0.91)中,C677T 与神经病变风险之间的关系均无显著统计学意义。在调整了几个混杂因素后,仍然没有明显的关联。我们的结论是,我们人群中的 C677T 并不影响神经病变风险。在未来的研究中,应该对神经病变的具体标准和实验室参数进行研究。关键词MTHFR、神经病变、二甲双胍和 T2DM
