Finger millet is commonly cultivated in the semiarid tropics, where it is primarily grown by subsistence farmers. However, grain yield remains low due to the complex quantitative nature of the trait and its low heritability. Therefore, genotype × environment interaction (GEI) significantly influences yield production. This study investigates the impact of GEI on the performance of finger millet genotypes across multiple environments, emphasizing the crop's sensitivity to climate variability. The objectives of this study were to evaluate the effects of genotype, environment, and GEI on yield and identifying high-yielding stable genotypes. Multienvironment trials (METs) were conducted at Axum, Negele Arsi, and Assosa during the 2018 and 2019 in summer cropping seasons utilizing row-column designs and advanced statistical analyses, including additive main effects and multiplicative interaction (AMMI) and genotype and genotype × environment interaction (GGE) biplot analyses. AMMI analysis indicated substantial environmental effects, with interaction principal component axes accounting for over 80% of the GEI. The GGE biplot identified the relationships between environments, highlighting specific genotypes that are optimal for each environment. Genotype G32, with a yield of 2.75-ton ha-1, showed the highest mean yield values and the highest stability metrics using mean ranks and cultivar superiority stability values of 0.12 and of 9.0, respectively. Genotype G53 was the most stable, with a variance of ranks of 17.60, mean absolute difference of pairs of ranks of 4.90, and Wricke's ecovalence of 0.02. The choice of stability measures is critical, depending on plant breeders' objectives and the heritable traits targeted. Hence, genotype G32 had the highest grain yield performance and the most stable genotype and recommended for wider production in finger millet growing areas. Finally, the study demonstrates that AMMI and GGE are effective methods for selecting superior genotypes in diverse environments, providing valuable insights for finger millet breeding programs.

小米通常种植在半干旱的热带地区,主要由自给自足的农民种植。然而,由于该性状复杂的数量性质和低遗传力,籽粒产量仍然很低。因此,基因型与环境互作(GEI)对产量有显著影响。本研究探讨了不同环境下GEI对谷子基因型生产性能的影响,强调了谷子对气候变异的敏感性。本研究的目的是评价基因型、环境和GEI对产量的影响,并确定高产稳定的基因型。利用行列设计和先进的统计分析,包括加性主效应和乘法相互作用(AMMI)以及基因型和基因型×环境相互作用(GGE)双图分析,于2018年和2019年夏种植季在Axum、Negele Arsi和Assosa进行了多环境试验(METs)。AMMI分析表明,交互主成分轴对环境的影响较大,占全球环境影响的80%以上。GGE双标图确定了环境之间的关系,突出了对每种环境最优的特定基因型。G32以2.75 t hm -1产量表现出最高的平均产量和最高的稳定性指标(平均等级和品种优势稳定性),分别为0.12和9.0。基因型G53最稳定,秩方差为17.60,对秩平均绝对差为4.90,Wricke生态价为0.02。稳定性措施的选择是至关重要的,这取决于植物育种者的目标和所针对的遗传性状。因此,基因型G32具有最高的产量表现和最稳定的基因型,推荐在谷子产区推广生产。研究结果表明,AMMI和GGE是在不同环境下选择优良基因型的有效方法,为谷子育种规划提供了有价值的见解。

The present study aimed to determine whether sole or joint Se treatments improve wheat growth under drought conditions. The study was conducted using two wheat varieties, BARI Gom30 and BARI Gom33, at the Agronomy Research Field of Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the Rabi season from December 2023 to April 2024. A randomized complete block design with three replications was employed. Wheat plants were grown under drought conditions in the field, and seedlings in each plot were subjected to six treatments: T0 (control, no selenium), T1 (10 ppm Se), T2 (20 ppm Se), T3 (30 ppm Se), T4 (40 ppm Se), and T5 (50 ppm Se) per plot. The results indicated that the highest plant height (103.35 cm), number of leaves per plant (5.50), number of tillers per plant (5.00), leaf area (5125.95 mm2), leaf temperature (26.53°C), spike length (17.75 cm), and biological yield (4.33 t ha-1) were observed in the T5 treatment (50 ppm Se per plot). However, the maximum grain yield was obtained with T3 (30 ppm Se). The highest harvest index was recorded in the T4 treatment (40 ppm Se), suggesting its effectiveness in optimizing yield distribution. Additionally, physiological parameters such as chlorophyll content, carotenoid levels, relative water content, water saturation deficit, water retention capacity, water use efficiency, leaf succulence, excised leaf water loss, and cell membrane stability showed slightly higher peak values in BARI Gom33 (V2), indicating its superior drought tolerance and yield potential. Based on the findings, a Se concentration of 50 ppm (T5 × V2) was identified during the interaction as the most effective treatment for enhancing the growth of the selected wheat varieties (V2) under drought conditions.

本研究旨在确定单独或联合硒处理是否能促进干旱条件下小麦的生长。这项研究是在2023年12月至2024年4月的拉比季期间,在迪纳杰布尔哈吉穆罕默德达内什科技大学农学研究领域使用两个小麦品种BARI Gom30和BARI Gom33进行的。采用随机完全区组设计,共3个重复。在大田干旱条件下,每个地块的幼苗分别进行T0(对照,无硒)、T1 (10 ppm Se)、T2 (20 ppm Se)、T3 (30 ppm Se)、T4 (40 ppm Se)和T5 (50 ppm Se) 6个处理。结果表明:T5 (50 ppm Se /田)处理的单株株高(103.35 cm)、单株叶数(5.50)、分蘖数(5.00)、叶面积(5125.95 mm2)、叶温(26.53°C)、穗长(17.75 cm)和生物产量(4.33 t hm -1)最高;T3 (30 ppm Se)处理籽粒产量最高。收获指数最高的是T4处理(40 ppm Se),表明其在优化产量分配方面的有效性。此外,叶绿素含量、类胡萝卜素水平、相对含水量、水分饱和亏缺、保水能力、水分利用效率、叶片多肉质、切除叶片水分损失和细胞膜稳定性等生理参数在BARI Gom33 (V2)中表现出略高的峰值,表明其具有较好的耐旱性和产量潜力。综上所述,硒浓度为50 ppm (T5 × V2)是促进小麦品种(V2)在干旱条件下生长的最有效处理。

Cassava cultivation faces increasing challenges from diseases, particularly cassava mosaic virus. Efficient propagation systems are essential for producing disease-free plants and sustaining production. However, information on the agronomic, physiological, growth traits, and yield of cassava plantlets produced through rapid propagation remains limited. This study aimed to investigate the photosynthetic and agronomic traits, as well as the growth and yield, of cassava plantlets derived from an aeroponic system under both pot and field conditions, using a 3 × 4 factorial arrangement in a randomized complete block design (RCBD). Three cassava varieties-Kasetsart 50 (KU50), Rayong 9 (RY9), and Huay Bong 60 (HB60)-were assigned as Factor A, while four plantlet sources-three derived from aeroponic systems (leaf bud cuttings, mini-cuttings, and normal cuttings) and one from conventional cuttings-were assigned as Factor B. The results indicated that HB60 and RY9 exhibited superior growth, stem diameter, photosynthesis rate, stomatal conductance, transpiration, and higher yields. Notably, RY9 also showed greater plant height and stem diameter, contributing to a higher multiplication rate. Plantlet sources did not significantly affect photosynthetic traits under either pot or field conditions but did increase canopy height, starch yield in the field, and starch content in the pot. Interestingly, the performance of leaf bud cuttings, mini-cuttings, and normal cuttings was comparable to conventional planting methods in terms of photosynthetic traits, yield traits, and harvest index. These findings suggest similarities among cassava cultivars in their responses to different plantlet sources and highlight the potential value of plantlet sources as a consideration for plant propagation programs.

木薯种植面临越来越多的疾病挑战,特别是木薯花叶病毒。高效的繁殖系统是生产无病植物和维持生产的必要条件。然而,关于木薯快速繁殖植株的农艺、生理、生长性状和产量的信息仍然有限。采用随机完全区组设计(RCBD),采用3 × 4因子设计,研究盆栽和大田条件下气培系统木薯幼苗的光合和农艺性状、生长和产量。3个木薯品种kasetsart 50 (KU50)、Rayong 9 (RY9)和Huay Bong 60 (HB60)被指定为因子A, 4个植株来源(3个来自气培系统(叶芽扦插、小扦插和普通扦插)和1个来自常规扦插)被指定为因子b。结果表明,HB60和RY9在生长、茎粗、光合速率、气孔导度和蒸腾作用方面表现优异,产量较高。值得注意的是,RY9的株高和茎粗也较大,有助于提高繁殖率。在盆栽和田间条件下,植株来源对光合性状没有显著影响,但增加了冠层高度、田间淀粉产量和盆栽淀粉含量。有趣的是,叶芽扦插、迷你扦插和正常扦插在光合性状、产量性状和收获指数方面的表现与常规种植方法相当。这些发现表明,木薯品种对不同植株来源的反应具有相似性,并突出了植株来源作为植物繁殖计划考虑的潜在价值。

Background: The marginal gap increases the rate of bacterial leakage and treatment failure; the measurement of the marginal gap is questionable. The literature revealed that when bacteria get trapped within the smear layer, they can multiply and re-contaminate the root canal system, leading to treatment failure.

Methodology: A literature search was carried out in multiple databases, including PubMed, Web of Science, Scopus, and ScienceDirect, with the help of MeSH terms such as Bacterial infection, Bacterial leakage, Dental leakage, Dental material, Root canal preparation, Root canal obturation, and Tooth penetration.

Result: The initial result of the search showed 2252 articles that were relevant enough. However, only 26 articles were eligible based on inclusion criteria.

Conclusion: The bacterial leakage test can evaluate one of the most essential properties of dental material: sealing ability. The sealing ability of a dental material can prevent bacterial ingestion and reduce the treatment failure rate. This study discussed all the steps of the bacterial leakage test in detail. This study can help the researcher plan and run a bacterial leakage study successfully, and the results can help clinicians choose the best sealing material for the clinical scenario.

背景:边缘间隙增加了细菌漏出率和治疗失败率;边际差距的测量是有问题的。文献显示,当细菌被困在涂片层中时,它们可以繁殖并重新污染根管系统,导致治疗失败。方法:在PubMed、Web of Science、Scopus、ScienceDirect等多个数据库中检索文献,检索MeSH术语如细菌感染、细菌渗漏、牙科渗漏、牙科材料、根管准备、根管封闭、牙齿穿透等。结果:最初的搜索结果显示了2252篇足够相关的文章。然而,根据纳入标准,只有26篇文章符合条件。结论:细菌渗漏试验可以评价口腔材料最重要的性能之一:密封能力。牙科材料的密封能力可以防止细菌摄入,降低治疗失败率。本文详细讨论了细菌泄漏试验的各个步骤。这项研究可以帮助研究人员成功地计划和运行细菌泄漏研究,结果可以帮助临床医生选择最佳的临床场景密封材料。

AI-based chatbots are increasingly used to automate clinical documentation, but their efficacy in generating specialized nutritional prescriptions for hospital discharge remains underexplored. This preliminary study evaluated the performance of a prominent AI chatbot in producing clinically valid nutritional guidelines. A specialist committee of registered dietitians selected 16 common medical and surgical pathologies. Standardized prompts were used to generate nutritional discharge guidelines from the chatbot. The same committee then evaluated the AI-generated texts for technical accuracy and content presentation on a 0-10 scale (approval score ≥ 7.0). Inter-rater reliability was assessed using the intraclass correlation coefficient (ICC) and Cohen's Kappa. Overall, 50% (8/16) of the AI-generated prescriptions met the predefined approval threshold. Performance was higher for medical pathologies (mean score: 7.1 ± 1.2) compared to surgical pathologies (6.6 ± 1.4), although this difference was not statistically significant (p > 0.05). Inter-rater reliability was substantial (ICC > 0.72; Kappa > 0.62). The findings indicate that AI chatbots hold promise as supplementary tools for drafting nutritional discharge summaries, potentially reducing administrative workload. However, their variable performance underscores the indispensable need for rigorous review and validation by qualified healthcare professionals before any clinical application.

基于人工智能的聊天机器人越来越多地用于自动化临床记录,但它们在为出院患者生成专门营养处方方面的功效仍未得到充分探索。这项初步研究评估了一个杰出的人工智能聊天机器人在制定临床有效的营养指南方面的表现。由注册营养师组成的专家委员会选出16种常见的内科和外科病理。标准化的提示被用来从聊天机器人生成营养排泄指南。然后,同一委员会对人工智能生成的文本的技术准确性和内容呈现进行了0-10级的评估(批准分数≥7.0)。采用类内相关系数(intraclass correlation coefficient, ICC)和Cohen’s Kappa法评估评等间信度。总体而言,ai生成的处方中有50%(8/16)符合预定义的审批阈值。内科病理评分(平均得分:7.1±1.2)高于外科病理评分(平均得分:6.6±1.4),但差异无统计学意义(p < 0.05)。评估间信度相当高(ICC > 0.72; Kappa > 0.62)。研究结果表明,人工智能聊天机器人有望成为起草营养出院摘要的补充工具,有可能减少行政工作量。然而,它们的可变性能强调了在任何临床应用之前由合格的医疗保健专业人员进行严格审查和验证的必要性。

Cellular metabolism is a key regulator of tissue repair and regeneration, with mitochondrial function playing a central role in energy production and cellular homeostasis. Dysfunctional mitochondria, often due to excessive reactive oxygen species (ROS), contribute to oxidative stress, impaired wound healing, and chronic inflammation. This study investigates the therapeutic potential of DeepA-I, a Boron-enriched compound, in enhancing mitochondrial health, reducing oxidative damage, and promoting cellular repair in human umbilical vein endothelial cells (HUVEC) and mouse embryonic fibroblasts (MEF). Boron quantification via inductively coupled plasma optical emission spectroscopy (ICP-OES) confirmed its presence in DeepA-I. Cytotoxicity assessment (MTT assay) demonstrated its safety, while fluorescence microscopy (DAPI, MitoSPY, DCFDA) revealed reduced ROS levels and preserved mitochondrial integrity. A scratch assay showed accelerated cell migration and wound closure in DeepA-I-treated cells. Western blot analysis indicated the downregulation of Akt (a proliferation marker) and the upregulation of NRF2, a key regulator of oxidative stress resistance, without affecting apoptosis-related proteins. These results suggest that DeepA-I, via its Boron-mediated mechanisms, enhances mitochondrial function, mitigates ROS-induced damage, and improves tissue repair, positioning it as a promising therapeutic candidate for inflammatory and degenerative conditions.

细胞代谢是组织修复和再生的关键调节因子,线粒体功能在能量产生和细胞稳态中起着核心作用。线粒体功能失调,通常是由于活性氧(ROS)过多,导致氧化应激、伤口愈合受损和慢性炎症。本研究探讨了富硼化合物deepa - 1在改善人脐静脉内皮细胞(HUVEC)和小鼠胚胎成纤维细胞(MEF)线粒体健康、减少氧化损伤和促进细胞修复方面的治疗潜力。通过电感耦合等离子体光学发射光谱(ICP-OES)对硼进行定量分析,证实了其在DeepA-I中的存在。细胞毒性评估(MTT试验)显示其安全性,而荧光显微镜(DAPI, MitoSPY, DCFDA)显示ROS水平降低并保持线粒体完整性。划痕实验显示,deepa - i处理的细胞加速了细胞迁移和伤口愈合。Western blot分析显示,Akt(增殖标志物)下调,NRF2(氧化应激抵抗的关键调节因子)上调,但不影响凋亡相关蛋白。这些结果表明,deepa - 1通过其硼介导的机制,增强线粒体功能,减轻ros诱导的损伤,改善组织修复,将其定位为炎症和退行性疾病的有希望的治疗候选者。

Introduction: Filamentous fungi are crucial for the production of commercial enzymes, organic acids, antibiotics, and many other organic compounds. Citric, acetic, and gluconic acids are among the organic acids that are produced from fungi and have many functions. They are mostly used as a chemical reagent, fungicide, herbicide, microbicide, pH adjuster, counterirritant, and solvent in a variety of industries, including food, agriculture, cleaning, and cosmetics.

Objectives: This study aimed to study the diversity of selected organic acids (citric, acetic, and gluconic acids) produced by filamentous fungi isolated from the agricultural soils of North Gondar, Ethiopia.

Methods: In this study, a total of 36 soil samples were randomly collected from agricultural fields at different locations in North Gondar, Ethiopia. The isolates were identified to the genus and species level based on morphological study and sequencing methods (ITS1-5·8S-ITS2 region). Their distribution was evaluated with respect to different agroecologies (climate conditions). The organic acid production capacity of the isolates was evaluated.

Results: Based on the results of morphological characteristics and ITS1-5·8S-ITS2 region gene sequencing, 12 filamentous fungi were obtained. All 12 filamentous fungal isolates had one common ancestor and belonged to Aspergillus terreus (KIA, KIC, KID, and KIG), Aspergillus nidulans (KIB), Aspergillus niger (KIF), Penicillium chrysogenum (KIH), Penicillium brevicompactum (KII), Talaromyces pinophilus (KIJ), Penicillium kongii (KIK), Penicillium paraherquei (KIL), and Talaromyces sp. (KIM). Among these, three of them, namely, KIA, KIH, and KIF, were found to be the best producers of acetic acid, citric acid, and gluconic acid, respectively.

Conclusion: Organic acid-producing filamentous fungi could be isolated from varied agroecologies.

Background: Human papillomavirus-induced plane warts represent benign cutaneous lesions that, despite frequent spontaneous resolution, demonstrate persistence and recurrence patterns associated with considerable cosmetic and psychological morbidity. Isotretinoin has emerged as a therapeutic consideration for recalcitrant plane warts. We evaluated isotretinoin effectiveness and safety in the management of plane warts through a systematic analysis of available clinical evidence.

Methods: We conducted this systematic review following Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, with prospective registration in PROSPERO (ID: CRD420251060689). Comprehensive searches of PubMed, Scopus, and EMBASE databases were extended through November 2024. Primary efficacy outcomes focused on isotretinoin-induced changes in wart lesion characteristics.

Results: Fifteen studies met the inclusion criteria, comprising six clinical trials, one cross-sectional study, six case reports, and two case series conducted across seven countries, encompassing 438 patients. Complete resolution rates demonstrated substantial variation, ranging from 38% to 87.5%. Among 10 studies documenting adverse events, cheilitis and dry skin emerged as the most common side effects.

Conclusion: Oral isotretinoin shows promise for recalcitrant plane warts, but current evidence is heterogeneous and largely of moderate-to-low quality. These findings are insufficient to support routine clinical use at this time; well-designed, adequately powered randomized controlled trials with standardized dosing and outcomes are needed.

背景:人乳头瘤病毒引起的平面疣是一种良性皮肤病变,尽管经常自发消退,但具有持久性和复发模式,与相当大的美容和心理发病率相关。异维甲酸已成为一种治疗顽固性平面疣的考虑。通过对现有临床证据的系统分析,我们评估了异维甲酸治疗平面疣的有效性和安全性。方法:我们按照系统评价和荟萃分析指南的首选报告项目进行了本系统评价,在PROSPERO (ID: CRD420251060689)进行了前瞻性注册。PubMed、Scopus和EMBASE数据库的综合搜索扩展到2024年11月。主要疗效结果集中在异维甲酸诱导的疣病变特征的变化。结果:15项研究符合纳入标准,包括6项临床试验、1项横断面研究、6例病例报告和2个病例系列,涉及7个国家的438名患者。完全分辨率变化很大,从38%到87.5%不等。在记录不良事件的10项研究中,口唇炎和皮肤干燥是最常见的副作用。结论:口服异维甲酸治疗顽固性平面疣有希望,但目前的证据是不一致的,大部分是中低质量的。这些发现不足以支持目前的常规临床应用;需要设计良好、动力充足、剂量和结果标准化的随机对照试验。

One approach to mitigating plastic pollution is the development of biodegradable plastic materials, such as bioplastics. Bioplastics are packaging materials that can be naturally degraded by microorganisms. In this study, bioplastics were produced using natural polymer compounds, specifically carrageenan and starch. The combination of starch and carrageenan was investigated to develop bioplastic packaging (shopping bags) with improved properties. This study aimed to evaluate the effect of incorporating different types of starch (corn, sago, and cassava) into carrageenan-based bioplastics on their physicochemical and mechanical characteristics. The research involved the fabrication of bioplastics using a combination of carrageenan and various starches (corn, sago, and cassava), followed by characterization, including moisture content, thickness, tensile strength, elongation at break, functional group analysis using Fourier transform infrared (FTIR) spectroscopy, and surface morphology analysis using scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEM-EDS). Additionally, water vapor transmission rate (WVTR), thermogravimetric analysis (TGA), and biodegradation tests were conducted following the ASTM G21 standard. The results indicated that starch variation did not significantly affect the mechanical properties, morphology, or biodegradation characteristics of the carrageenan-starch bioplastics.

减轻塑料污染的一种方法是开发可生物降解的塑料材料,如生物塑料。生物塑料是可以被微生物自然降解的包装材料。在这项研究中,生物塑料是用天然聚合物化合物,特别是卡拉胶和淀粉生产的。研究了淀粉与卡拉胶的复合制备性能较好的生物塑料包装(购物袋)。本研究旨在评估将不同类型的淀粉(玉米、西米和木薯)加入到卡拉胶基生物塑料中对其物理化学和机械特性的影响。该研究涉及使用卡拉胶和各种淀粉(玉米,西米和木薯)的组合来制造生物塑料,然后进行表征,包括含水量,厚度,拉伸强度,断裂伸长率,使用傅里叶变换红外(FTIR)光谱进行官能团分析,以及使用扫描电子显微镜-能量色散x射线光谱(SEM-EDS)进行表面形貌分析。此外,水蒸气透过率(WVTR)、热重分析(TGA)和生物降解测试按照ASTM G21标准进行。结果表明,淀粉含量的变化对卡拉胶-淀粉生物塑料的力学性能、形态和生物降解特性没有显著影响。
