This study provides a comprehensive characterization of the unsaponifiable matter (USM) in oils extracted from Pistacia atlantica fruits during prematurity phases (unripe and semiripe stages) from two distinct biogeographical regions in Algeria (Sougaa and Bousdraya). Notably, quantitative analysis revealed substantial variations in bioactive compound concentrations: tocopherols ranged from 3.10 to 17.88 mg αTE/g USM, sterols from 844.45 to 871.36 mg βS/g USM, and carotenoids from 15.22 to 20.76 mg βCE/g USM, demonstrating the significant phytochemical richness of early developmental stages. The USM components were quantified using validated spectrophotometric methods, with parallel evaluation of antioxidant and α-amylase inhibitory activities. The most remarkable finding was the exceptional antioxidant potency of semiripe fruits from Bousdraya (BRF), showing IC50 = 0.49 mg/mL, representing one of the strongest antioxidant activities reported for Pistacia species unsaponifiable fractions. The unripe sample from Sougaa (SRC) exhibited the highest USM yield (10.45%) along with superior carotenoid and sterol concentrations. Furthermore, semiripe fruits from Sougaa (SRF) demonstrated the strongest α-amylase inhibition (34.58 μmol acarbose Eq/g USM), highlighting their potential for diabetes management applications. Correlation analysis revealed a strong negative relationship between tocopherol content and antioxidant activity (r = -0.92), confirming their role as primary radical scavengers. The results provide crucial insights for developing functional ingredients for nutraceutical and pharmaceutical industries targeting oxidative stress and glycemic control. Initial stages of Pistacia atlantica fruit development represent an underappreciated source of valuable bioactive compounds. These results clearly indicate that an optimal harvesting strategy must consider both geographic origin and phenological stage, depending on the desired functional profile (e.g., semiripe BRF for strong antioxidant activity, immature SRC for maximum USM, and carotenoid/sterol yield). The key role in this activity was confirmed by a strong, statistically significant, negative correlation between tocopherol content and the IC50 value (r = -0.92). However, the highest alpha-amylase inhibition activity, significantly different from the immature samples (p < 0.05), was achieved by semiripe samples from Sougaa (SRF, 34.58 p.m. 1.33 mµmol AACE/g USM) and BRF, suggesting that other, statistically uncorrelated (r approx. 0.01 for tocopherols) compounds are responsible for this effect. In terms of content, the immature sample from Sougaa (SRC) was statistically superior in terms of carotenoid and sterol content. These findings definitively confirm that the selection of harvest site and time is critical for maximizing the functional quality of the oil.

本研究对来自阿尔及利亚两个不同的生物地理区域(Sougaa和Bousdraya)的大西洋开心果早熟期(未成熟和半成熟阶段)提取的油中的不皂化物质(USM)进行了全面的表征。值得注意的是,定量分析显示了生物活性化合物浓度的显著变化:生育酚在3.10 ~ 17.88 mg αTE/g USM之间,甾醇在844.45 ~ 871.36 mg βS/g USM之间,类胡萝卜素在15.22 ~ 20.76 mg βCE/g USM之间,显示了发育早期显著的植物化学丰富性。采用验证的分光光度法对USM成分进行定量,并对其抗氧化活性和α-淀粉酶抑制活性进行平行评价。最显著的发现是黄连木半熟果实(BRF)具有较强的抗氧化活性,IC50 = 0.49 mg/mL,是迄今为止报道的黄连木非皂化部位中抗氧化活性最强的部位之一。Sougaa (SRC)未成熟样品的USM产量最高(10.45%),类胡萝卜素和甾醇含量也较高。此外,高粱半熟果实(SRF) α-淀粉酶抑制作用最强(34.58 μmol阿卡波糖Eq/g USM),显示其在糖尿病治疗方面的应用潜力。相关分析显示,生育酚含量与抗氧化活性呈显著负相关(r = -0.92),证实了其作为自由基清除剂的作用。该结果为开发针对氧化应激和血糖控制的营养保健和制药行业的功能成分提供了重要的见解。大西洋黄连木果实发育的初始阶段是一种被低估的有价值的生物活性化合物的来源。这些结果清楚地表明,最佳的收获策略必须考虑地理来源和物候阶段,这取决于所需的功能特征(例如,半成熟的BRF具有强抗氧化活性,未成熟的SRC具有最大的USM,以及类胡萝卜素/固醇产量)。生育酚含量与IC50值呈显著负相关(r = -0.92),证实了生育酚在这一活性中的关键作用。然而,α -淀粉酶抑制活性最高,与未成熟样品有显著差异(p < 0.05)。0.01(生育酚)的化合物是造成这种效果的原因。在含量方面,Sougaa (SRC)的未成熟样品在类胡萝卜素和甾醇含量方面具有统计学优势。这些发现明确地证实了采收地点和时间的选择对于最大限度地提高油的功能质量至关重要。

Breast cancer, the most prevalent cancer worldwide, poses a significant public health challenge, especially in the advanced stages. According to the Saudi Health Council (2020), breast cancer is also the leading cancer in Saudi Arabia with recent increases in incidence rates. Over the past two decades, Saudi Arabia has made significant advancements in anti-breast cancer drug discovery driven by increased research funding, improved access to scientific resources, and enhanced education. This study aims to highlight Saudi Arabia's contributions to this field through a bibliometric analysis of anti-breast cancer drug discovery research published between 2019 and 2023. Using a comprehensive search strategy, 943 publications were retrieved from the Web of Science Core Collection (WoSCC) database and analyzed. Bibliometric tools such as VOSviewer and Microsoft Excel were used to highlight trends in publication output, research areas, and collaboration networks. The results reveal a steady increase in Saudi publications, rising from under 100 in 2019 to over 250 in 2023. The primary research areas were Chemistry (43.69%), Pharmacology/Pharmacy (23.65%), and Biochemistry (22.80%). Elsevier and MDPI were the leading publication platforms, while King Saud University was identified as the primary source of research funding (17.60%). Co-authorship networks revealed strong collaborations between Saudi institutions and international partners. The most frequent keywords reflected key research priorities within Saudi institutions, "anticancer", "molecular docking", and "nanoparticles". The most commonly studied therapeutic targets were EGFR, Caspase, and VEGF with a diverse range of therapeutic approaches including pyrimidines, nanoparticles, and natural products. This analysis highlights Saudi Arabia's growing contributions to the field of breast cancer drug discovery and provides a foundation for future research and collaboration.

Alzheimer's disease (AD), a complex neurodegenerative disorder, urgently necessitates a multitarget therapeutic approach. This study presents a novel in silico framework targeting a unique combination of four AD-relevant proteins-sortilin, clusterin, tau, and amyloid-beta (Aβ)-not previously explored together in multitarget docking studies. The study leveraged a comprehensive computational strategy integrating ADME (absorption, distribution, metabolism, excretion) and ProTox-3.0 analyses with AutoDock Vina molecular docking, binding, and bond interaction via SiteMap/CASTp and PLIP, respectively. Fifteen novel natural ligands and three established AD reference drugs (donepezil, memantine, and rivastigmine) were assessed against four key AD proteins: sortilin, clusterin, Aβ peptide, and tau. Pharmacokinetic and toxicity predictions revealed favorable drug-likeness for many ligands, 4-tert-amylphenol, allicin, apigenin, and resveratrol, which exhibited high gastrointestinal absorption but varied in blood-brain barrier (BBB) permeation, solubility, and drug-likeness. Ligands, such as apigenin, cyanidin, and galantamine, demonstrated favorable oral bioavailability and lead-likeness. Nevertheless, predicted toxicity profiles revealed potential hepatotoxicity concerns for ligands like 4-tert-amylphenol and berberine. Comparison with reference drugs highlighted the importance of optimizing ADME properties and minimizing toxicity. Molecular docking results consistently highlighted ginkgolide with multitarget binding to sortilin (-16.29 kcal/mol), clusterin (-13.98 kcal/mol), and tau (-10.63 kcal/mol). Critical interactions were identified, including binding to the aggregation domain of tau via HIS329. Other promising natural ligands, including ginsenosides, berberine, and apigenin, also exhibited strong multitarget interactions. Ginsenosides were a notable lead, demonstrating key molecular contacts with ILE141 on sortilin and directly targeting the Aβ core at ALA4. Apigenin also showed strong binding to the tau repeat domain at ILE328. Notably, memantine displayed significant binding to both sortilin and Aβ, forming a hydrogen bond with the amyloidogenic ILE5 residue. The study identified several potent multitarget binding capabilities compounds, offering compelling avenues for developing novel, more effective therapeutics for AD.

阿尔茨海默病(AD)是一种复杂的神经退行性疾病,迫切需要多靶点的治疗方法。本研究提出了一种新的硅框架,靶向四种ad相关蛋白-sortilin, clusterin, tau和淀粉样蛋白- β (a β)的独特组合,这些蛋白以前未在多靶点对接研究中一起探索。该研究利用综合计算策略,将ADME(吸收、分布、代谢、排泄)和ProTox-3.0分析与AutoDock Vina分子对接、结合和键相互作用分别通过SiteMap/CASTp和PLIP进行结合。15种新型天然配体和3种已建立的AD参比药物(多奈哌齐、美金刚和利瓦斯蒂明)对4种AD关键蛋白:sortilin、clusterin、Aβ peptide和tau进行了评估。药代动力学和毒性预测显示,许多配体(4-叔氨基酚、大蒜素、芹菜素和白藜芦醇)具有良好的药物相似性,它们具有较高的胃肠道吸收,但在血脑屏障(BBB)渗透性、溶解度和药物相似性方面存在差异。配体,如芹菜素、花青素和加兰他明,表现出良好的口服生物利用度和铅相似度。然而,预测的毒性谱显示了4-叔氨基酚和小檗碱等配体的潜在肝毒性问题。与参比药物的比较突出了优化ADME性能和最小化毒性的重要性。分子对接结果一致显示银杏内酯与sortilin (-16.29 kcal/mol)、clusterin (-13.98 kcal/mol)和tau (-10.63 kcal/mol)具有多靶点结合。确定了关键的相互作用,包括通过HIS329与tau聚集域的结合。其他有前途的天然配体,包括人参皂苷、小檗碱和芹菜素,也表现出强的多靶点相互作用。人参皂苷是一个值得注意的先导,证明了与sortilin上的ILE141的关键分子接触,并直接靶向ALA4上的a β核心。芹菜素在ILE328上也显示出与tau重复结构域的强结合。值得注意的是,美金刚显示出与sortilin和a β的显著结合,与淀粉样蛋白ILE5残基形成氢键。该研究确定了几种有效的多靶点结合能力化合物,为开发新的、更有效的阿尔茨海默病治疗方法提供了令人信服的途径。

The experiment was conducted using an alpha lattice design with two replications for each genotype, comprising 20 maize hybrids obtained from CIMMYT and NMRP, including two check varieties. The treatment genotypes were assessed during the spring season of 2024 at the agronomy farm of Gokuleshwor College, Baitadi. The tallest plant height of 293.298 cm was recorded in genotype RH-12, while the shortest, 231.598 cm, was observed in RML-95/RML-140. The observed variation among genotypes indicated that selection can be effectively carried out based on traits such as days to 50% anthesis, days to 50% silking, anthesis-silking interval, number of rows per cob, number of grains per row, cob length, cob diameter, and grain yield. Most of the evaluated morphological traits showed a strong correlation with grain yield, depicting that indirect selection could effectively enhance yield potential. Among the hybrids, CAH 1817 stood out with the highest grain yield, followed closely by NH2226 and VH 18567. These varieties show great potential and could be strong candidates for promoting higher-yielding maize hybrids in Nepal.

Antibiotic resistance and biofilm formation are becoming more common in uropathogenic Escherichia coli (UPEC). Hence, the study aims to determine the antibiogram of commonly prescribed antibiotics and assess prodigiosin's antibacterial activity against UPEC. During the study, 175 UPEC isolates were identified biochemically, and their antibiogram was studied by the VITEK 2 system. Prodigiosin was extracted from Serratia marcescens MTCC 97. The MIC of prodigiosin against UPEC strains was detected by the microbroth dilution method. The majority of the UPEC strains (n = 135) had MIC between 15 and 30 mg/mL. No significant association was observed between the MIC of prodigiosin and the antibiogram. Biofilm assay was performed by the microtiter plate method using media with and without added prodigiosin. In media without prodigiosin, most UPEC isolates were nonbiofilm formers (NBF-55.42%), followed by weak (21.14%), moderate (MBF-13.71%) and strong biofilm formers (SBF-9.7%). When the same test was performed in media with added prodigiosin, NBF decreased to 30.28%, while SBF, MBF and WBF increased to 20%, 26.85% and 22.85%, respectively. This change in biofilm production was statistically significant (p < 0.05, Wilcoxon signed-rank test). The effect of prodigiosin on fimH virulence gene was evaluated using PCR. The fimH gene was present in 159 (90.85%) isolates cultured in medium devoid of prodigiosin, whereas in prodigiosin-containing media, 132 (83.01%) isolates were positive for the fimH gene and 27 (16.98%) were negative (p < 0.05, McNemar's test), suggesting that the fimH-negative isolates had either considerable suppression of the gene's transcription or gene expression pathways. Further, biofilm production increased when prodigiosin inhibited the fimH gene, suggesting a gene-dependent reaction that may have compelled UPEC to adopt a stress-response phenotype that favours nonspecific surface attachment to form biofilm for survival. Therefore, the effect of prodigiosin on biofilms seems to be associated with the expression of fimH, indicating a gene-dependent response.

抗生素耐药性和生物膜形成在尿路致病性大肠杆菌(UPEC)中变得越来越常见。因此,本研究旨在确定常用抗生素的抗菌谱,并评价芥子红素对UPEC的抗菌活性。对175株UPEC分离株进行了生化鉴定,并用VITEK 2系统对其抗菌谱进行了研究。从粘质沙雷氏菌MTCC 97中提取了神曲菌素。用微肉汤稀释法测定了芥子皂苷对UPEC菌株的MIC。大多数UPEC菌株(n = 135)的MIC在15 ~ 30 mg/mL之间。抗菌谱与子黄素的MIC无显著相关性。生物膜试验采用微滴板法,培养基中分别添加和不添加芥子红。在不含菌红素的培养基中,大多数UPEC分离菌为非生物成膜菌(NBF-55.42%),其次为弱(21.14%)、中等(MBF-13.71%)和强生物成膜菌(SBF-9.7%)。在添加prodigiosin的培养基中进行相同的试验,NBF降低到30.28%,SBF、MBF和WBF分别提高到20%、26.85%和22.85%。这种生物膜产量的变化具有统计学意义(p . fimH毒力基因用PCR进行了评估。在不含prodigiosin的培养基中,有159株(90.85%)分离到fimH基因,而在含prodigiosin的培养基中,有132株(83.01%)分离到fimH基因阳性,27株(16.98%)分离到fimH基因阴性(p < 0.05, McNemar’s test),说明fimH阴性分离株对该基因的转录或表达途径有明显的抑制作用。此外,当prodigiosin抑制fimH基因时,生物膜的产生增加,这表明一种基因依赖性反应可能迫使UPEC采用应激反应表型,这种表型有利于非特异性表面附着形成生物膜以生存。因此,芥绿素对生物膜的影响似乎与fimH的表达有关,表明这是一种基因依赖性反应。

We conducted this study to evaluate the protective effects of Epigallocatechin-3-gallate (EGCG) against epilepsy in rats, with a specific focus on its potential to mitigate oxidative stress, inflammation, and apoptosis. Epilepsy was induced in rats using pentylenetetrazol (PTZ), followed by treatment with 20 mg/kg of EGCG. The effects of EGCG were assessed on seizure severity and frequency, as well as acetylcholinesterase (AChE) activity. Brain sections were stained with cresyl violet and immune-stained with anti-Nrf2 antibody. Furthermore, expressions and concentrations of B-Cell Lymphoma 2 (BCL2), Nuclear Factor Erythroid 2-Related Factor-2 (Nrf2), nuclear factor κB (NFκB), BCL2-associated X (BAX), tumor necrosis factor-α (TNF-α), and Interleukin-1 β (IL-1β) in brain tissues were analyzed. Rats showed significant behavioral improvement following EGCG treatment. Analysis of the dentate gyrus sections demonstrated a modest increase in the staining intensity of Nissl granules after EGCG. Additionally, EGCG was observed to increase the expression levels of BCL2, Nrf2, and Heme Oxygenase-1 (HO-1), while concurrently reducing the expression of BAX, NF-κB, TNF-α, and IL-1β. In conclusion, EGCG demonstrates protective effects against epilepsy. The underlying mechanisms may be attributed to its capacity to increase antioxidant activity by the upregulation of Nrf2 and HO-1. EGCG appears to mitigate inflammation by downregulating NF-κB, TNF-α, and IL-1β, thereby decreasing cellular apoptosis through the downregulation of BAX and upregulation of BCL-2.

我们进行了这项研究,以评估表没食子儿茶素-3-没食子酸酯(EGCG)对大鼠癫痫的保护作用,特别关注其减轻氧化应激、炎症和细胞凋亡的潜力。用戊四唑(PTZ)诱导大鼠癫痫,然后用20 mg/kg的EGCG治疗。评估EGCG对癫痫发作严重程度、发作频率以及乙酰胆碱酯酶(AChE)活性的影响。脑切片用甲酚紫染色,抗nrf2抗体免疫染色。分析脑组织中b细胞淋巴瘤2 (BCL2)、核因子红系2相关因子-2 (Nrf2)、核因子κB (NFκB)、BCL2相关X (BAX)、肿瘤坏死因子-α (TNF-α)、白细胞介素-1β (IL-1β)的表达和浓度。大鼠在EGCG治疗后表现出明显的行为改善。齿状回切片分析显示,EGCG后尼塞尔颗粒的染色强度略有增加。此外,EGCG还能提高BCL2、Nrf2和血红素加氧酶-1 (HO-1)的表达水平,同时降低BAX、NF-κB、TNF-α和IL-1β的表达。总之,EGCG对癫痫有保护作用。其潜在机制可能是通过上调Nrf2和HO-1来增加抗氧化活性。EGCG似乎通过下调NF-κB、TNF-α和IL-1β来减轻炎症,从而通过下调BAX和上调BCL-2来减少细胞凋亡。

Spodoptera frugiperda (fall armyworm) is an exotic pest from the American continent that has invaded agricultural lands in Indonesia, particularly affecting maize crops. This study aimed to investigate the biological and morphometric characteristics of S. frugiperda larvae fed with baby corn under controlled laboratory conditions. Several biological parameters were observed, including the preoviposition, oviposition, and postoviposition periods, egg production and frequency, and the number of larval instars. The study also monitored the duration of the prepupal and pupal stages, mortality rates, sex ratios, adult lifespan, and body size. Results indicated that S. frugiperda exhibits high reproductive capacity, with females laying an average of 133.25 eggs that hatch within 1-2 days. Larvae underwent six instars over 14-16 days, and the pupal stage lasted 9-11 days before emerging as adults. Male adults lived for 6-8 days, while females survived longer, between 9 and 13 days. The total lifespan from egg to adult death averaged 30 days for males and 35 days for females. High mortality was observed in the pupal stage and the first larval instar. Morphometric data revealed gradual increases in larval length from the first instar (2.25 mm) to the sixth instar (32 mm), with pupae reaching 16 mm in length, and adults measuring 14 and 13 mm for males and females, respectively. The relatively small body size of S. frugiperda contributes to its ability to disperse and invade agricultural areas in Indonesia. This study provides valuable insights into the biology and morphometrics of S. frugiperda, which may serve as a foundation for developing sustainable pest management strategies in the region.

夜蛾(Spodoptera frugiperda)是一种来自美洲大陆的外来害虫,已入侵印度尼西亚的农田,尤其影响玉米作物。本研究旨在研究在控制的实验室条件下,以玉米幼仔为食的frugiperda幼虫的生物学和形态特征。观察了产卵前、产卵期、产卵期、产卵次数、幼虫数等生物学参数。该研究还监测了蛹前和蛹期的持续时间、死亡率、性别比例、成虫寿命和体型。结果表明,沙蚕具有较高的繁殖能力,1 ~ 2 d内平均产卵133.25枚。幼虫在14 ~ 16 d内经历6个龄期,蛹期为9 ~ 11 d,形成成虫。雄成虫寿命6-8天,雌成虫寿命更长,在9 - 13天之间。从卵到成虫死亡的总寿命雄性平均为30天,雌性为35天。蛹期和第一幼虫期死亡率较高。形态测量数据显示,从1龄(2.25 mm)到6龄(32 mm),幼虫体长逐渐增加,雄雌蛹体长可达16 mm,成虫体长分别为14 mm和13 mm。相对较小的体型有助于其在印度尼西亚分散和入侵农业区的能力。本研究为该地区沙蚕的生物学和形态计量学研究提供了有价值的见解,可为该地区制定可持续的害虫防治策略提供依据。

Polypharmacy, commonly defined as the concurrent use of five or more medications, is a pressing public health concern among older adults with cardiovascular disease, given its strong association with adverse drug-drug interactions, medication errors, and increased hospitalization rates. Despite its clinical significance, evidence from low- and middle-income countries, including Iran, remains limited. This study sought to determine the prevalence of polypharmacy and identify its key determinants among elderly cardiovascular patients in Kermanshah, Iran. In this cross-sectional survey of 426 participants, eligible participants were recruited using convenience sampling, and demographic, clinical, and medication-related data were collected using structured questionnaires. Statistical analyses, including chi-square tests and multivariate logistic regression, were employed to examine associations. The findings revealed that 60.1% of participants were taking five to nine medications daily. Polypharmacy was significantly associated with lower educational attainment and income, prolonged treatment duration, hospitalization history, multimorbidity, insufficient pharmacist counseling, and limited knowledge of medications and their potential adverse effects. Multivariate analysis identified the number of chronic conditions (AOR: 5.05, p < 0.001), hospitalization history (AOR: 5.15, p < 0.001), and poor medication knowledge (AOR: 6.48, p = 0.017), as independent predictors. These results highlight the urgent need for targeted, evidence-based interventions, particularly pharmacist-led counseling and patient education programs, to mitigate the burden and adverse clinical outcomes of polypharmacy, especially in resource-constrained healthcare settings.

多药,通常定义为同时使用五种或更多种药物,是老年心血管疾病患者迫切关注的公共卫生问题,因为它与不良药物相互作用、用药错误和住院率增加密切相关。尽管具有临床意义,但来自包括伊朗在内的低收入和中等收入国家的证据仍然有限。本研究旨在确定伊朗Kermanshah老年心血管患者中多种用药的流行情况,并确定其关键决定因素。本次横断面调查共纳入426名参与者,采用方便抽样方法招募符合条件的参与者,采用结构化问卷收集人口学、临床和药物相关数据。统计分析,包括卡方检验和多元逻辑回归,用于检验相关性。研究结果显示,60.1%的参与者每天服用5到9种药物。多种用药与受教育程度低、收入低、治疗时间长、住院史、多病、药师咨询不足、对药物及其潜在不良反应的了解有限显著相关。多因素分析发现,慢性疾病数量(AOR: 5.05, p < 0.001)、住院史(AOR: 5.15, p < 0.001)和不良用药知识(AOR: 6.48, p = 0.017)是独立预测因素。这些结果强调,迫切需要有针对性的、基于证据的干预措施,特别是药剂师主导的咨询和患者教育计划,以减轻多重用药的负担和不良临床结果,特别是在资源有限的医疗保健环境中。

Plant invasion modifies the aboveground and belowground biota directly or indirectly via allelopathic effect. This study aimed to ascertain if the invasive species Alternanthera philoxeroides impacts plant diversity, plant composition, and soil microbes or not. The soil microbial activity (CO2 release) and soil pH were also recorded. The plant communities invaded and uninvaded with Alternanthera philoxeroides were examined using the quadrat method. Soil samples were collected from 0 to 10 cm depth, and the culture method was used for soil microbial analysis. The plant species richness and soil fungi were found to be reduced at A. philoxeroides invaded plots than at uninvaded plots. The IVI of all common species such as Cynodon dactylon, Bidens pilosa, and Trifolium repens was highly suppressed in the invaded zone. The parameters like plant diversity indices, colony count of soil microbes, soil microbial activity (CO2 release), and soil pH were found to be reduced at invaded sites than at uninvaded sites. The results indicated that the invasive A. philoxeroides modifies the plant community composition, and the underlying mechanism for the change is possibly by altering the soil microbiota, microbial respiration, and soil pH with their successful invasion.

植物入侵通过化感作用直接或间接地改变地上和地下生物群。摘要本研究旨在探讨外来入侵植物互花菊对植物多样性、植物组成和土壤微生物的影响。同时记录了土壤微生物活性(CO2释放)和pH值。采用样方法对被侵染和未侵染的植物群落进行了调查。土壤取样深度为0 ~ 10 cm,采用培养法进行土壤微生物分析。结果表明,黄杨入侵地的植物物种丰富度和土壤真菌数量明显低于未入侵地。在入侵区,长爪蟹、毛毛拜登、三叶草等常见树种的IVI均受到高度抑制。入侵样地的植物多样性指数、土壤微生物菌落数、土壤微生物活性(CO2释放)和土壤pH值均低于未入侵样地。结果表明,黄花蓟马入侵后改变了植物群落组成,其机制可能是通过改变土壤微生物群、微生物呼吸和土壤pH值来实现的。

Shiitake mushrooms (Lentinus edodes (Berk.) Sing.) have been widely recognized for their bioactive properties, including antimicrobial activity. This study aimed to investigate the antibacterial potential and chemical composition of shiitake mushroom extracts prepared using different solvents (95% ethanol, ethyl acetate, and chloroform). The highest extraction yield (31.16%) was obtained with 95% ethanol. The antimicrobial activity of the extracts was evaluated using the paper disc diffusion method against nine pathogenic bacterial isolates, including Gram-positive (Bacillus cereus, Staphylococcus aureus, and S. aureus DMST20654) and Gram-negative (Escherichia coli, E. coli ATCC25922, Enterobacter cloacae, Pseudomonas aeruginosa, Serratia marcescens, and Salmonella enterica serovar Typhi ATCC16122) bacteria. Plates were incubated at 37°C for 24 h. All experiments were performed in triplicate. The ethyl acetate extract exhibited the strongest antibacterial activity, with the largest inhibition zone observed for E. coli ATCC25922 (30.00 ± 0.00 mm), followed by S. enterica serovar Typhi ATCC16122 (28.33 ± 2.00 mm). The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays confirmed the superior antibacterial potential of the ethyl acetate extract, particularly against S. aureus DMST20654 (MIC = 1.95 mg/mL, MBC = 31.25 mg/mL). Gas chromatography-mass spectrometry (GC-MS) analysis identified key bioactive compounds, including ergosterol (62.38%, %Prob 62.6 in the chloroform extract) and linoleic acid (28.65%, %Prob 56.5 in the ethyl acetate extract), which are known for their antimicrobial properties. The findings highlight the potential of ethyl acetate-extracted shiitake mushroom compounds as natural antibacterial agents, with applications for food preservation, nutraceuticals, and pharmaceuticals.

香菇(Lentinus edodes))因其生物活性,包括抗菌活性而被广泛认可。研究了不同溶剂(95%乙醇、乙酸乙酯和氯仿)制备的香菇提取物的抑菌活性和化学成分。当乙醇浓度为95%时,提取率最高,为31.16%。采用纸片扩散法对革兰氏阳性菌株(蜡样芽孢杆菌、金黄色葡萄球菌和金黄色葡萄球菌DMST20654)和革兰氏阴性菌株(大肠杆菌、大肠杆菌ATCC25922、阴沟肠杆菌、铜绿假单胞菌、粘质沙雷菌和伤寒沙门氏菌ATCC16122)进行抑菌活性评价。37℃孵育24 h。所有的实验都是三次重复。乙酸乙酯提取物抑菌活性最强,对大肠杆菌ATCC25922(30.00±0.00 mm)的抑菌带最大,其次是伤寒链球菌ATCC16122(28.33±2.00 mm)。最小抑菌浓度(MIC)和最小杀菌浓度(MBC)试验证实乙酸乙酯提取物具有较好的抑菌效果,对金黄色葡萄球菌DMST20654 (MIC = 1.95 mg/mL, MBC = 31.25 mg/mL)具有较好的抑菌效果。气相色谱-质谱(GC-MS)分析确定了主要的生物活性化合物,包括麦角甾醇(62.38%,氯仿提取物中约62.6 %)和亚油酸(28.65%,乙酸乙酯提取物中约56.5 %),这些化合物以其抗菌特性而闻名。这一发现突出了乙酸乙酯提取的香菇化合物作为天然抗菌剂的潜力,在食品保鲜、营养食品和药品方面具有应用价值。
