This study investigated the proximate composition and inhibitory potential of hot water and ethanolic extracts of the pulp, peel and whole fruit of green banana (Musa sapientum) on α-amylase and α-glucosidase. Bioactive compounds were identified using GC-MS analysis. In addition, the cytotoxic effect on human gingival fibroblast (hGF) was evaluated using the sulphorhodamine B (SRB) assay. The results showed that the peel of green banana had the highest amount of ash (10.05%), fat (2.83%), protein (3.64%) and total dietary fibre (36.62%). The carbohydrate content of the whole fruit (81.79%) and pulp (81.50%) was higher than that of the peel (71.90%). The moisture content of the pulp (13.08%) was higher than that of the peel (11.58%) and whole fruit (11.30%). The ethanolic green banana peel extract showed a good inhibitory effect of α-amylase and α-glucosidase with the concentration necessary for 50% inhibition (IC50) of 0.512 and 0.100 mg·mL-1, respectively. The α-glucosidase inhibitory effect of the ethanolic green banana peel extract and the hot water green banana peel extract was not significantly different from that of acarbose (IC50 0.108 mg·mL-1). GC-MS analysis of the ethanolic green banana peel extract revealed fatty acids and fatty acid ester (9-octadecenamide (Z), octadecanamide and other compounds). The ethanolic peel extract exhibits a significant noncytotoxicity effect on hGF cells at concentrations ranging from 0.0001 to 1.0 mg·mL-1.

本研究调查了青香蕉(Musa sapientum)果肉、果皮和整个果实的近似成分以及热水和乙醇提取物对α-淀粉酶和α-葡萄糖苷酶的抑制潜力。利用气相色谱-质谱分析鉴定了生物活性化合物。此外,还利用硫代多巴胺 B(SRB)测定法评估了对人牙龈成纤维细胞(hGF)的细胞毒性作用。结果表明,青香蕉果皮的灰分(10.05%)、脂肪(2.83%)、蛋白质(3.64%)和总膳食纤维(36.62%)含量最高。全果(81.79%)和果肉(81.50%)的碳水化合物含量高于果皮(71.90%)。果肉的水分含量(13.08%)高于果皮(11.58%)和整个果实(11.30%)。青香蕉皮乙醇提取物对α-淀粉酶和α-葡萄糖苷酶有很好的抑制作用,抑制 50%所需的浓度(IC50)分别为 0.512 和 0.100 mg-mL-1。绿香蕉皮乙醇提取物和绿香蕉皮热水提取物对α-葡萄糖苷酶的抑制作用与阿卡波糖(IC50 0.108 mg-mL-1)相比没有显著差异。青香蕉皮乙醇提取物的气相色谱-质谱分析显示了脂肪酸和脂肪酸酯(9-十八烯酰胺(Z)、十八烯酰胺和其他化合物)。在 0.0001 至 1.0 毫克/毫升-1 的浓度范围内,乙醇青香蕉皮提取物对 hGF 细胞具有明显的无细胞毒性作用。

Milk is an essential part of the human diet and is a nutrient-rich food that improves nutrition and food security. The aim of this study was to determine the presence and concentration of aflatoxin M1 (AFM1), adulterants, microbial loads, and physicochemical properties of raw cow's milk (CM) in Nekemte City, Ethiopia. A total of 12 samples of fresh CM were purposefully collected from four kebeles in the city (Bake Jama, Burka Jato, Cheleleki, and Bakanisa Kese) based on the potential of each milk production and distributor site. The AFM1 concentration was determined by high-performance liquid chromatography (HPLC) with a Sigma-Aldrich standard (St. Louis, MO, USA). The concentrations of AFM1 in Bake Jama, Burka Jato, Cheleleki, and Bakanisa Kese were found to be 0.01-0.03 g/L, 0.31-0.35 g/L, 0.19-0.21 g/L, and 0.04-0.07 g/L, respectively. The concentrations of AFM1 in the present study varied significantly (p < 0.05) and ranged from 0.01 g/L to 0.35 g/L. These results show that of the 12 samples tested, all were positive for AFM1 and contaminated to varying degrees. The results of this study also revealed that the concentration of AFM1 in 7 (58%) of the 12 milk samples was above the European Union's (EU) maximum tolerance limit (0.05 g/L). The present study also revealed that of the investigated adulterants, only the addition of water had positive effects on three milk samples, while the remaining adulterants were not detected in any of the milk samples. The total bacterial count (TBC) and total coliform count (TCC) were significantly (p < 0.05) different and ranged from 5.53 to 6.82 log10cfumL-1 and from 4.21 to 4.74 log10cfumL-1, respectively. The physicochemical properties of the milk samples in the present study were significantly (p < 0.05) different and ranged from 2.8% to 5.75% fat, 7.03% to 9.75% solid-not-fat (SNF), 2.35% to 3.61% protein, 3.33% to 5.15% lactose, 11.54% to 13.69% total solid, 0.16% to 0.18% titratable acid, 26.7 to 32.1°C, 6.35 to 6.55 pH, and 1.027 to 1.030 specific gravity. The physicochemical parameters of the raw milk in the study area met the required quality standards. Hence, further studies are required to determine the extent of the problem and the factors associated with high levels of AFM1 in raw milk in the study areas, including the detection of aflatoxin B1 (AFB1) in animal feed.

牛奶是人类膳食的重要组成部分,是一种营养丰富的食品,可改善营养状况,提高粮食安全。本研究旨在确定埃塞俄比亚内克姆特市生鲜牛乳(CM)中黄曲霉毒素 M1(AFM1)、掺杂物、微生物负荷和理化特性的存在和浓度。根据每个牛奶生产和销售地点的潜力,从该市的四个区(Bake Jama、Burka Jato、Cheleleki 和 Bakanisa Kese)有目的地采集了共 12 份新鲜 CM 样品。AFM1 浓度采用高效液相色谱法 (HPLC) 和 Sigma-Aldrich 标准品(美国密苏里州圣路易斯市)进行测定。发现 Bake Jama、Burka Jato、Cheleleki 和 Bakanisa Kese 中的 AFM1 浓度分别为 0.01-0.03 克/升、0.31-0.35 克/升、0.19-0.21 克/升和 0.04-0.07 克/升。本研究中 AFM1 的浓度变化很大(p < 0.05),从 0.01 克/升到 0.35 克/升不等。这些结果表明,在检测的 12 个样本中,所有样本的 AFM1 均呈阳性,并受到不同程度的污染。研究结果还显示,12 个牛奶样本中有 7 个样本(58%)的 AFM1 浓度超过了欧盟(EU)规定的最高耐受限度(0.05 克/升)。本研究还显示,在所调查的掺杂物中,只有加水对三个牛奶样本有积极影响,其余掺杂物在任何牛奶样本中均未检测到。细菌总数(TBC)和大肠菌群总数(TCC)差异显著(p < 0.05),分别为 5.53 至 6.82 log10cfumL-1 和 4.21 至 4.74 log10cfumL-1。本研究中牛奶样品的理化性质差异显著(p < 0.05),脂肪含量从 2.8% 到 5.75%,固形脂肪(SNF)含量从 7.03% 到 9.75%,蛋白质含量从 2.蛋白质含量为 2.8%至 5.75%,固形物含量为 7.03%至 9.75%,蛋白质含量为 2.35%至 3.61%,乳糖含量为 3.33%至 5.15%,总固体含量为 11.54%至 13.69%,可滴定酸含量为 0.16%至 0.18%,温度为 26.7 至 32.1°C,pH 值为 6.35 至 6.55,比重为 1.027 至 1.030。研究区原料奶的理化参数符合规定的质量标准。因 此 , 我 们 需 要 进 一 步 研 究 , 以 确 定 问 题 的 严 重 性 , 以 及 研 究 地 区 的 生 奶 中 含 高 量 AFM1 的 相 关 因 素 , 包 括 在 动 物 饲 料 中 检 测 到 的 黄 曲 霉 毒 素 B1 ( AFB1 ) 。

Lake Hayq is one of the highland lakes of Ethiopia that furnishes very important ecosystem services, fishing, tourism, transportation, drinking water, livestock watering, and irrigation. However, the lake ecosystem is being degraded by pollution, siltation, and excessive growth of macrophytes, buffer zone degradation, overfishing, and climate variability. Therefore, this study was conducted to assess the physicochemical, heavy metals, and biological water quality parameters of Lake Hayq. Physiochemical (pH, water temperature, conductivity, TDS, total alkalinity, dissolved oxygen, Ca2+, Mg2+, Na+, K+, NH4+, NH3, NO2 -, NO3 -, CO3 -, HCO3 -, SO4 2-, PO4 3-, SiO2, and total phosphorus), heavy metals (Pb, Fe, Zn, Cr, Cu2+, Mn2+, and Ni), and biological (BOD5 and total coliforms) water quality parameters were analyzed both in situ and ex situ. The physicochemical parameters were measured using portable water quality measuring multimeters, the heavy metal analysis was done using the Atomic Absorption Spectrometer, the BOD5 was measured using a BOD5 meter, and the total coliform analysis was done using the spread plate technique. The collected data were analyzed using multivariate, two-way ANOVA to see the mean difference among sampling sites and seasons through the application of SPSS 16. Most of the water quality parameters of Lake Hayq have met the WHO standards for recreation, aquatic life, and drinking water quality. However, some parameters, such as Pb, BOD5, and total coliforms, were above WHO water quality permissible limits. Therefore, ecohydrological (nature-based) waste treatment methods such as macrophyte restoration in buffer zones and ecofriendly farming activities should be practiced to minimize the contamination of the lake.

海克湖是埃塞俄比亚的高原湖泊之一,为渔业、旅游业、交通、饮用水、牲畜饮水和灌溉提供了非常重要的生态系统服务。然而,由于污染、淤积、大型水生植物过度生长、缓冲区退化、过度捕捞和气候多变,湖泊生态系统正在退化。因此,本研究对 Hayq 湖的物理化学、重金属和生物水质参数进行了评估。理化参数(pH 值、水温、电导率、TDS、总碱度、溶解氧、Ca2+、Mg2+、Na+、K+、NH4+、NH3、NO2-、NO3-、CO3-、HCO3-、SO4 2-、PO4 3-、SiO2、和总磷)、重金属(Pb、Fe、Zn、Cr、Cu2+、Mn2+ 和 Ni)以及生物(BOD5 和总大肠菌群)水质参数进行了现场和非现场分析。理化参数使用便携式水质测量万用表测量,重金属分析使用原子吸收光谱仪,生化需氧量 5 使用生化需氧量 5 计测量,总大肠菌群分析使用展板技术。收集到的数据使用 SPSS 16 进行了多元、双向方差分析,以了解不同采样点和不同季节的平均差异。海克湖的大部分水质参数都符合世界卫生组织的娱乐、水生生物和饮用水水质标准。然而,一些参数,如铅含量、生化需氧量 5 和总大肠菌群,则超过了世界卫生组织的水质允许限值。因此,应采用生态水文(以自然为基础)废物处理方法,如在缓冲区恢复大型植物和生态友好型农业活动,以尽量减少对湖泊的污染。

Background: Najaf governorate was recorded as one of the most polluted Iraqi governorates with increased cancer, autoimmune, and abortion cases. Study Groups. A total of 88 adult volunteers from three test groups were divided based on their inhabitance in different geographical regions in Najaf governorate. Group 1 (G1; n, 29) inhabitants of Al-Ansar, Al-Abbaseyeh, and Al-Manathera districts, Group 2 (G2; n, 27) inhabitants of 22 different scattered districts of the governorate, Group 3 (G3; n, 32) inhabitants of Kufa city and center districts in the old Najaf city. According to previous authors' findings, all participants had uranium contamination in their urine and blood samples, and also, they had DNA damage according to the level of urinary 8-OHdG compound. The control group 4 (G4; n, 25) were adult healthy Iraqi volunteers who were residents of the Sulaimaniyah governorate, which has low-level uranium pollution. The present study aims to determine the effect of uranium pollution and DNA damage on the immune system function in terms of estimating the levels of serum interleukin (IL)-6, interferon-gamma (IFN-γ), and IL-1 beta (β).

Method: Enzyme-linked immunosorbent assay (ELISA) (Sandwich method technique) was used for estimating the serum cytokines levels in test and control groups.

Results: A significant elevation of cytokines levels was reported as compared with the control groups (p ≤ 0.01). The level of IL-6 was 764.64 ± 24.12 pg/ml, 768.87 ± 19.64 pg/ml, and 735.62 ± 18.47 in G1, G2, and G3, respectively. The level of IFN-γ was 264.55 ± 19.17 pg/ml, 259 ± 18.76 pg/ml, and 261.20 ± 12.99 pg/ml for G1, G2, and G3, respectively. The level of IL-1β was 99.85 ± 10.81 pg/ml, 116.8 ± 10.71 pg/ml, and 83 ± 19.24 pg/ml in G1, G2, and G3, respectively. The levels of IL-6, IFN-γ, and IL-1β were 86.5 ± 22.9 pg/ml, 19.4 ± 2.8 pg/ml, and 16.1 ± 3.2 pg/ml in the sera of control (G4). The results showed significant statistical elevation with the corresponding p value cut-off p ≤ 0.01 in IL-6, IFN-γ, and IL-1β in the sera of three test groups as compared with the results of the control group.

Conclusion: The change in the proinflammatory cytokines (IL-6, IFN-γ, and IL-1β) levels indicates a persistent inflammatory response in the participants and may reflect immune system impairment as a consequence of exposure to long-term low-dose ionizing radiation.

背景据记录,纳杰夫省是伊拉克污染最严重的省份之一,癌症、自身免疫和流产病例都有所增加。研究小组。根据居住在纳杰夫省不同地理区域的情况,将三个测试组共 88 名成年志愿者分为三组。第一组(G1;n,29)为 Al-Ansar、Al-Abbaseyeh 和 Al-Manathera 区的居民;第二组(G2;n,27)为该省 22 个不同分散区的居民;第三组(G3;n,32)为库法市和纳杰夫老城中心区的居民。根据作者之前的研究结果,所有参与者的尿液和血液样本中都含有铀污染,而且根据尿液中 8-OHdG 复合物的含量,他们的 DNA 都受到了损伤。对照组 4(G4;n,25)是健康的伊拉克成年志愿者,他们是苏莱曼尼亚省的居民,该省的铀污染程度较低。本研究旨在通过估算血清白细胞介素 (IL)-6、γ 干扰素 (IFN-γ) 和 IL-1 beta (β) 的水平,确定铀污染和 DNA 损伤对免疫系统功能的影响:方法:采用酶联免疫吸附试验(ELISA)(三明治法技术)估测试验组和对照组的血清细胞因子水平:结果:与对照组相比,试验组的细胞因子水平明显升高(P ≤ 0.01)。G1、G2 和 G3 组的 IL-6 水平分别为 764.64 ± 24.12 pg/ml、768.87 ± 19.64 pg/ml 和 735.62 ± 18.47。IFN-γ的水平在G1、G2和G3中分别为264.55 ± 19.17 pg/ml、259 ± 18.76 pg/ml和261.20 ± 12.99 pg/ml。G1、G2 和 G3 的 IL-1β 水平分别为 99.85 ± 10.81 pg/ml、116.8 ± 10.71 pg/ml 和 83 ± 19.24 pg/ml。对照组(G4)血清中 IL-6、IFN-γ 和 IL-1β 的水平分别为 86.5 ± 22.9 pg/ml、19.4 ± 2.8 pg/ml 和 16.1 ± 3.2 pg/ml。结果显示,与对照组的结果相比,三个试验组血清中的 IL-6、IFN-γ 和 IL-1β 均有明显的统计学升高,相应的 p 值临界值 p≤ 0.01:结论:促炎细胞因子(IL-6、IFN-γ 和 IL-1β)水平的变化表明参与者体内存在持续的炎症反应,这可能反映了长期暴露于低剂量电离辐射导致的免疫系统损伤。

Utilities face serious obstacles from power theft, which calls for creative ways to maintain income and improve operational effectiveness. This study presents a novel hybrid genetic artificial hummingbird algorithm-support vector machine classifier to detect power theft. The proposed algorithm combines the artificial hummingbird algorithm exploration phase with the genetic algorithm's mutation and crossover operators, to optimize the support vector machine's hyperparameters and categorize users as fraudulent or nonfraudulent. It utilizes 7,270 rows of labeled historical electricity consumption data from the Liberia Electricity Corporation over 15 independent runs. The methodology entailed data preprocessing, data split into training, validation, and testing sets in an 80-10-10 ratio, z-score normalization, optimization, training, validation, testing, and computation of six evaluation metrics. Its performance is compared with 13 metaheuristic classifiers and the conventional support vector machine. Findings indicate that the genetic artificial hummingbird algorithm-support vector machine outperforms the 13 rivals and the standard support vector machine in the six assessment measures with an accuracy score of 0.9986, precision of 0.9971, f_score of 0.9986, recall of 1, Matthews correlation coefficient of 0.9972, and g_mean of 0.9987. Furthermore, 90% of the time, Wilcoxon rank-sum tests revealed statistically significant differences between the algorithm and its rivals, demonstrating its superiority. The average run time is 4,656 seconds, the 3rd highest among its competitors. Despite the time complexity trade-off, its excellent performance on the unimodal and multimodal benchmark test functions, placing joint best in 7 out of 7 and 5 out of 6, respectively, provides important insights into the model's capacity to balance exploitation and exploration, improve local search, and avoid becoming stuck in the local optimum. These findings address important metaheuristic optimization gaps highlighting the model's potential for power theft detection.

电力公司面临着严重的窃电障碍,这就要求采用创新方法来维持收入和提高运营效率。本研究提出了一种新型混合遗传人工蜂鸟算法-支持向量机分类器来检测窃电行为。所提出的算法将人工蜂鸟算法的探索阶段与遗传算法的突变和交叉算子相结合,以优化支持向量机的超参数,并将用户分为欺诈和非欺诈用户。它利用利比里亚电力公司提供的 7,270 行标注的历史用电数据进行了 15 次独立运行。该方法包括数据预处理、按 80-10-10 的比例将数据分成训练集、验证集和测试集、z-score 归一化、优化、训练、验证、测试和六个评估指标的计算。它的性能与 13 种元启发式分类器和传统的支持向量机进行了比较。结果表明,在六项评估指标中,遗传人工蜂鸟算法-支持向量机的准确度为 0.9986,精确度为 0.9971,f_score 为 0.9986,召回率为 1,马修斯相关系数为 0.9972,g_mean 为 0.9987,优于 13 个对手和标准支持向量机。此外,在 90% 的情况下,Wilcoxon 秩和检验显示该算法与其竞争对手之间存在显著的统计学差异,这证明了该算法的优越性。平均运行时间为 4656 秒,在竞争对手中排名第三。尽管在时间复杂度上有所权衡,但该算法在单模态和多模态基准测试功能上的出色表现,分别在 7 个基准测试功能中的 7 个和 6 个基准测试功能中的 5 个中名列前茅,为该模型平衡开发与探索、改进局部搜索和避免陷入局部最优的能力提供了重要启示。这些发现弥补了元启发式优化的重要不足,凸显了该模型在窃电检测方面的潜力。

Process discovery approaches analyze the business data to automatically uncover structured information, known as a process model. The quality of a process model is measured using quality dimensions, completeness (replay fitness), preciseness, simplicity, and generalization. Traditional process discovery algorithms usually output a single process model. A single model may not accurately capture the observed behavior and overfit the training data. We have formed the process discovery problem in a multiobjective framework that yields several candidate solutions for the end user who can pick a suitable model based on the local environmental constraints (possibly varying). We consider the Binary Differential Evolution approach in a multiobjective framework for the task of process discovery. The proposed method employs dichotomous crossover/mutation operators. The parameters are tuned using grey relational analysis combined with the Taguchi approach. We have compared the proposed approach with the well-known single-objective algorithms and state-of-the-art multiobjective evolutionary algorithm-Nondominated Sorting Genetic Algorithm (NSGA-II). Additional comparison via computing a weighted average of the quality dimensions is also undertaken. Results show that the proposed algorithm is computationally efficient and produces diversified candidate solutions that score high on the fitness functions. It is shown that the process models generated by the proposed approach are superior to or at least as good as those generated by the state-of-the-art algorithms.

流程发现方法通过分析业务数据来自动发现结构化信息,即流程模型。流程模型的质量是通过质量维度、完整性(重放适配性)、精确性、简单性和概括性来衡量的。传统的流程发现算法通常只输出一个流程模型。单一模型可能无法准确捕捉观察到的行为,并且会过拟合训练数据。我们将流程发现问题纳入一个多目标框架,为最终用户提供多个候选解决方案,用户可根据本地环境约束条件(可能不断变化)选择一个合适的模型。我们考虑在多目标框架下采用二元差分进化法来完成流程发现任务。所提出的方法采用了二分交叉/突变算子。参数的调整采用灰色关系分析与田口方法相结合的方法。我们将提出的方法与著名的单目标算法和最先进的多目标进化算法--非优势排序遗传算法(NSGA-II)进行了比较。此外,还通过计算质量维度的加权平均值进行了比较。结果表明,所提出的算法计算效率高,并能产生多样化的候选解决方案,在适应度函数上得分较高。结果表明,拟议方法生成的流程模型优于或至少与最先进算法生成的流程模型一样好。

Traditional medicinal plants (TMPs) are a significant part of people's quality of life, offering a natural substitute for modern drugs with numerous side effects. In Tanzania, data on antiasthmatic TMPs are highly fragmented. This review, a comprehensive compilation of ethnobotanical research evidence, aimed to provide a thorough understanding of TMPs used by the locals for asthma management and identify species that have already been investigated in preclinical studies. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. To gather relevant literature on antiasthmatic TMPs used by Tanzanians, a web search using electronic databases (Scopus, PubMed, ProQuest, Academic Library, Web of Science, SciFinder, Wiley Online Library, Google Scholar, ScienceDirect, and African Journals Online) was conducted. The scientific names were verified through the Plants of the World Online database, and the collected information was analysed for descriptive statistics using Microsoft Excel software. The ethnomedicinal information was obtained from 24 different articles. Microsoft Excel software was used to analyse the data using descriptive statistics. A total of 62 TMPs belonging to 33 families were identified. Species of the Fabaceae (14.5%) and Rubiaceae families (8.1%) are the most utilized. The analysis revealed that trees (42.0%) and leaves (40.0%) are the most utilized life forms and plant parts, respectively. Most plant materials (59.7%) used to make remedies were collected from the wild environment. Decoction (55.0%) is the dominant preparation method of remedies, and the majority (69.0%) were orally administered. Of the recorded TMPs, 22.6% had their in vivo antiasthmatic activity reported in the literature. The review also highlighted the strategic significance of preparations of remedies made from TMPs for discovering and developing new antiasthmatic drugs. However, the need to identify the molecular targets of action and toxicological aspects of the TMPs should be considered.

传统药用植物(TMPs)是提高人们生活质量的重要组成部分,是具有多种副作用的现代药物的天然替代品。在坦桑尼亚,有关抗哮喘 TMP 的数据非常零散。本综述是对人种植物学研究证据的全面汇编,旨在全面了解当地人用于治疗哮喘的 TMPs,并确定已在临床前研究中进行调查的物种。该综述是根据系统综述和元分析首选报告项目(PRISMA)声明进行的。为了收集有关坦桑尼亚人使用的抗喘息性 TMP 的相关文献,我们使用电子数据库(Scopus、PubMed、ProQuest、学术图书馆、Web of Science、SciFinder、Wiley Online Library、Google Scholar、ScienceDirect 和 African Journals Online)进行了网络搜索。通过世界植物在线数据库核实了学名,并使用 Microsoft Excel 软件对收集到的信息进行了描述性统计分析。民族药用信息来自 24 篇不同的文章。使用 Microsoft Excel 软件对数据进行描述性统计分析。共鉴定出隶属于 33 个科的 62 种 TMPs。使用最多的是豆科(14.5%)和茜草科(8.1%)的物种。分析显示,树木(42.0%)和树叶(40.0%)分别是利用最多的生命形式和植物部分。大多数用于制作药方的植物材料(59.7%)都是从野生环境中采集的。煎煮法(55.0%)是主要的药方配制方法,大多数(69.0%)是口服给药。在记录的 TMPs 中,有 22.6% 的体内抗哮喘活性在文献中有所报道。综述还强调了由 TMPs 制成的药剂对于发现和开发新的抗哮喘药物的战略意义。不过,还需要考虑确定 TMPs 的分子作用靶点和毒理学方面的问题。

This research aims to create and evaluate an assessment tool termed Older Adults' First Aid Knowledge Scale, which measures the knowledge and attitude of Iranian grandparents about first aid. In accordance with COSIM guidelines, 485 individuals in southern Iran completed the instrument as part of a psychometric investigation. Rasch partial credit model (PCM), exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and receiver operating characteristic (ROC) analysis were used to analyze the results. The final version of OFAKS consisted of 18 items that were validated through EFA, CFA, and item response theory (IRT) analysis. All items showed measurement invariance and consecutive response groupings in the predictable order, and the instrument had strong internal consistency. Although Rasch's analysis demonstrated the significance of OFAKS, further investigations and testing in different settings are required to confirm the validity of the tool.

Background: This study aims to evaluate the accuracy rate of foramen magnum dimensions in determining sex among the South Indian population using discriminant functional analysis.

Methods: An observational study in which CBCT images from 200 full field of view (FOV) scans were analysed. The dimensions of the foramen magnum were measured. Intra- and interobserver reliability were calculated. Independent t-tests were used to compare the various parameters between sexes. Stepwise discriminant function analysis was used to determine sex.

Results: A total of 200 CBCT scans were included in the study. The mean age (±SD) was 25.66 (±7.11) years among males and 24.64 (±5.12) years among females. The measurements and the circumference of the foramen magnum were significantly (p < 0.001) greater in males than in females. The univariate analysis of foramen magnum measurements reached an accuracy rate of 73.5% in sex determination. The discriminant function analysis combining the foramen magnum measurements and circumference yielded an overall predictability rate of 66.5% for determining sex.

Conclusion: Taking into account the predictability rate of sex based on foramen measurement in the present population, it can be concluded that its applicability should be limited to cases associated with fragmentary skull bases.

The flavonoid compounds in C. caudatus K., known for their various benefits, are prone to quick degradation, leading to reduced biological activity. This research aimed to evaluate the types of coatings: gum Arabic (GA), maltodextrin (MD), and a combination of both (MDGA) in C. caudatus K. extract microcapsules. The extract of C. caudatus K. was encapsulated by different coating materials, GA, MD, and MDGA, and then dried using a freeze-drying technique. The evaluation was carried out by comparing the encapsulation efficiency values, biological activity, and release tests of each type of microcapsule coating. The research results indicate that coating agents have impacts significantly at p < 0.05 on efficiency encapsulation. Flavonoids were retained up to 79.67% by the MDGA coating, compared with 72.8% and 47.66%a retained by single GA and MD coatings, respectively. The results of the encapsulation efficiency are supported by the results of characterization using a scanning electron microscope (SEM), where MDGA has rounder shapes with smoother surfaces compared with a single coating alone, like GA or MD. In addition, by particle size analysis using a particle size analyzer (PSA), the average sizes of MDGA, GA, and MD microcapsules were shown at 154.13 µm, 152 µm, and 166.81 µm, respectively. The three microcapsules showed an order of activities as MDGA > GA > MD coatings in alpha-amylase inhibition assay. Similar results were also shown in the antioxidant assay, which demonstrated that the three microcapsules had moderate antioxidant activities, again in the order of MDGA > GA > MD. The three different coating types showed greater release at pH 7.4 compared to those at pH 2.2 in the controlled release test, which ran from 30 to 120 min. In summary, freeze-drying microencapsulation using biodegradable polymers was identified as a viable method for harnessing the health benefits of C. caudatus K. extracts. This process produced a convenient powder form that could be used in drug delivery systems. The use of MDGA mixed coating resulted in better impact based on %EE value and biological activity, as well as improved characteristics of microcapsules compared with single coating.

草履虫中的黄酮类化合物以其各种功效而闻名,但容易快速降解,导致生物活性降低。本研究旨在评估 C. caudatus K. 提取物微胶囊中的包衣类型:阿拉伯树胶(GA)、麦芽糊精(MD)以及两者的组合(MDGA)。用不同的包衣材料(阿拉伯树胶、麦芽糊精和麦芽糖糊精)对尾根草提取物进行包囊,然后使用冷冻干燥技术进行干燥。通过比较每种微胶囊包衣的包囊效率值、生物活性和释放试验进行了评价。研究结果表明,包衣剂对包囊效率的影响显著(p < 0.05)。MDGA包衣对黄酮类化合物的保留率高达79.67%,而单一GA和MD包衣对黄酮类化合物的保留率分别为72.8%和47.66%a。使用扫描电子显微镜(SEM)进行表征的结果也证实了封装效率的结果,与 GA 或 MD 等单一涂层相比,MDGA 的形状更圆,表面更光滑。此外,通过使用粒度分析仪(PSA)进行粒度分析,MDGA、GA 和 MD 微胶囊的平均粒度分别为 154.13 微米、152 微米和 166.81 微米。在α-淀粉酶抑制实验中,三种微胶囊的活性顺序为 MDGA > GA > MD 涂层。抗氧化试验也显示了类似的结果,三种微胶囊都具有中等程度的抗氧化活性,其顺序同样是 MDGA > GA > MD。在 30 到 120 分钟的控释试验中,三种不同类型的包衣在 pH 值为 7.4 时比 pH 值为 2.2 时的释放量更大。总之,使用生物可降解聚合物进行冷冻干燥微胶囊化被认为是利用尾叶芹提取物健康益处的可行方法。这种工艺生产出的粉末形式非常方便,可用于给药系统。与单一包衣相比,使用 MDGA 混合包衣在 %EE 值和生物活性方面产生了更好的影响,并改善了微胶囊的特性。
