Marek's disease caused by Marek's disease virus (MDV) serotype 1 is an economically important neoplastic disease of poultry. Diagnosis of this disease is usually based on clinical signs, postmortem lesions, and diagnostic tests like cytology, histopathology, and molecular-based methods. However, there might be the problem of inaccurate diagnosis in Nigeria. Employment of gross pathology, histopathology, immunohistochemistry, and polymerase chain reaction (PCR) coupled with sequence analysis provides a reliable approach to arrive at precise confirmatory diagnosis of the disease. Therefore, visceral organs including liver, proventriculus intestine, spleen, and heart samples were collected at postmortem examinations from two pullets suspected of having Marek's disease. Histopathology and immunohistochemistry, PCR amplification of a 576 bp fragment of the MDV glycoprotein L (gL) gene, and sequence analysis were employed in this diagnostic approach. Histopathological examinations of the liver, heart and proventriculus showed neoplastic pleomorphic cellular infiltration comprising lymphoblasts, lymphocytes, macrophages, and heterophils which correspond with the pathology of Marek's disease. Liver samples were positive for the virus using PCR. Sequence analysis based on phylogenetic tree reconstruction revealed the positive MDV. MDV sequences from this study clustered with MDV serotype 1 sequences retrieved from the GenBank. This approach provides a reliable and precise diagnosis of Marek's disease in chickens which is applicable to other avian diseases.

马立克病是由马立克病病毒(MDV)血清型1引起的一种重要的家禽肿瘤性疾病。这种疾病的诊断通常基于临床症状、死后病变和诊断测试,如细胞学、组织病理学和基于分子的方法。然而,尼日利亚可能存在诊断不准确的问题。采用大体病理学、组织病理学、免疫组织化学和聚合酶链反应(PCR)与序列分析相结合,提供了一种可靠的方法来精确确诊该疾病。因此,从两只疑似马立克病的小母鸡的死后检查中采集了内脏器官,包括肝脏、前室肠、脾脏和心脏样本。该诊断方法采用组织病理学和免疫组织化学,PCR扩增MDV糖蛋白L (gL)基因576 bp片段,并进行序列分析。肝、心、脑室前组织病理学检查显示肿瘤多形性细胞浸润,包括淋巴细胞、淋巴细胞、巨噬细胞和嗜杂细胞,符合马立克病的病理特征。肝脏样本经PCR检测呈病毒阳性。基于系统发育树重建的序列分析显示MDV阳性。本研究的MDV序列与从GenBank检索到的MDV血清1型序列聚集在一起。该方法为鸡马立克病的诊断提供了可靠、准确的依据,可应用于其它禽类疾病的诊断。

There has been a recent rise in the utilization of complementary herbal medicines as a means to discover efficacious alternative treatments that mitigate the negative consequences of pharmaceuticals. Colocasia affinis Schott is a member of the Araceae family, with various components such as the root, fruit, and leaves utilized for medicinal purposes. This study aims to explore the in vitro phytochemical, antioxidant, antimicrobial, anti-inflammatory, and thrombolytic properties of the ethanolic extract obtained from the leaves of C. affinis (EECA) using an experimental approach. The extract derived from EECA revealed the presence of secondary metabolites, including alkaloids, glycosides, flavonoids, tannins, steroids, saponins, carbohydrates, amides, phenols, and reducing sugars, and demonstrated remarkable antioxidant activity in the DPPH scavenging assay (IC50 = 60.36 μg/mL). Secondly, five clinical isolates of bacteria, namely, Escherichia coli, Salmonella paratyphi, Salmonella typhi, Pseudomonas aeruginosa, and Vibrio cholerae, were employed to examine the antimicrobial properties of EECA. In the context of thrombolytic activity, EECA demonstrated a noteworthy level of clot lysis (39.086 ± 0.570% and 23.111 ± 0.398%) at doses of 500 and 250 μg/mL, respectively, when compared to streptokinase. Furthermore, EECA exhibited a significant anti-inflammatory effect, as evidenced by the inhibition of protein denaturation (60.24 ± 1.49, 43.81 ± 1.76, and 30.83 ± 2.57) across concentration ranges of 500, 250, and 125 μg/mL. The findings indicated the presence of phytochemicals and notable free radical scavenging activity. EECA exhibited a broad range of antimicrobial activity, along with notable thrombolytic and anti-inflammatory effects. This investigation presents empirical evidence that supports the application of EECA in traditional medicine.

最近在利用补充草药作为一种手段,发现有效的替代治疗,减轻药物的负面影响已经上升。Colocasia affinis Schott是天南星科的一员,具有各种成分,如根,果实和叶子,可用于药用。本研究旨在通过实验方法,探讨从affinis (C. affinis)叶中提取的乙醇提取物的体外植物化学、抗氧化、抗菌、抗炎和溶栓特性。提取物中含有生物碱、苷类、黄酮类、单宁类、甾体、皂苷类、碳水化合物、酰胺类、酚类和还原糖等次生代谢产物,对DPPH具有明显的清除活性(IC50 = 60.36 μg/mL)。其次,采用大肠杆菌、副伤寒沙门菌、伤寒沙门菌、铜绿假单胞菌和霍乱弧菌等5种临床分离菌对EECA的抗菌性能进行检测。在溶栓活性方面,与链激酶相比,EECA在500和250 μg/mL剂量下分别表现出显著的凝块溶解水平(39.086±0.570%和23.111±0.398%)。此外,EECA在500、250和125 μg/mL浓度范围内对蛋白变性的抑制作用分别为60.24±1.49、43.81±1.76和30.83±2.57,具有显著的抗炎作用。结果表明,植物化学物质的存在和显著的自由基清除活性。EECA具有广泛的抗菌活性,以及显著的溶栓和抗炎作用。本研究提供实证支持EECA在传统医学中的应用。

This scoping review aims to synthesize the current clinical evidence on probiotics used in tuberculosis (TB). Systematic literature searches were conducted across PubMed, Scopus, and Embase databases to identify all studies using probiotics in TB. A total of six studies conducted between 2016 and 2023 were found and included in this review. All the studies incorporated probiotics supplementation not beyond the intensive phase of antitubercular therapy (ATT), ranging from three to eight weeks. Five out of six included studies focused on pulmonary TB. Probiotics alleviate adverse gastrointestinal and hepatic drug reactions, modulate gut microbiota, enhance barrier function, and influence immune responses. Therefore, probiotics are a potential adjunct therapy during the intensive phase of ATT. However, their long-term effects remain unexplored, highlighting the future research scope for well-designed longitudinal studies to explore their sustained benefits.

本综述旨在综合目前益生菌治疗结核病的临床证据。在PubMed、Scopus和Embase数据库中进行了系统的文献检索,以确定所有使用益生菌治疗结核病的研究。在2016年至2023年期间,共有6项研究被发现并纳入本综述。所有的研究都纳入了益生菌补充,但没有超过抗结核治疗(ATT)的强化阶段,范围从3到8周。6项纳入的研究中有5项关注肺结核。益生菌可减轻胃肠道和肝脏药物不良反应,调节肠道菌群,增强屏障功能,影响免疫反应。因此,益生菌是ATT强化阶段的潜在辅助治疗。然而,益生菌的长期效果仍未被探索,这突出了未来的研究范围,需要精心设计的纵向研究来探索其持续益处。

Cognitive behavioral therapy (CBT) is currently considered the gold standard of treatment, with its evidence-based framework widely used in healthcare. However, its implementation in real-world settings faces numerous challenges. Understanding the barriers and facilitators of CBT implementation is essential to improving its accessibility and effectiveness. A systematic search was conducted across multiple databases from 20/9/2024 to 10/10/2024, including PubMed, CINAHL, ProQuest, and Web of Science. Studies published in English from 1994 to 2024 were included. This systematic review was reported using the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and registered at the International Prospective Register of Systematic Reviews (Registered No. CRD42024570477). Qualitative, quantitative, and mixed-method studies were analyzed to identify key implementation challenges and enablers. Data extraction and quality assessments were performed using the Mixed Methods Appraisal Tool (MMAT) and the JBI critical appraisal tools. A total of 32 studies with 2082 participants were included in this review. Common barriers to CBT implementation included limited training opportunities for clinicians, high caseloads, organizational constraints, resistance to change, and inadequate funding. Digital literacy challenges and technical issues further hindered the adoption of internet-based CBT (iCBT). Facilitators included strong leadership support, structured training programs, stakeholder engagement, and the integration of digital and step-care approaches to enhance accessibility. The findings highlight the importance of addressing systemic, organizational, and individual-level barriers to improve the implementation of CBT. Strengthening clinician training, increasing institutional support, and leveraging digital solutions can enhance the accessibility and sustainability of CBT interventions. This review provides practical insights for policymakers, mental health professionals, and researchers working toward optimizing CBT implementation in diverse settings.

Tomatoes, as one of the main vegetables in the world, are facing increasingly greater cultivation challenges due to environmental changes. The challenges include abiotic stresses such as high temperatures, drought, and salinity, which significantly impact tomato growth. Melatonin, a hormone recognized for its function in the human sleep cycle, has surfaced as a potential remedy for improving plant resilience. This article explores the effects of melatonin on tomatoes, particularly under abiotic stress. A comprehensive literature search using Scopus, ScienceDirect, Web of Science, PubMed, and ProQuest ensures the synthesis of relevant scientific literature. This review reports that the melatonin content in tomatoes varies among plant organs and is influenced by environmental factors. The application of exogenous melatonin has been proven beneficial in stress conditions, enhancing antioxidant activities, photosynthesis, and stress resistance. The function of melatonin in gene regulation, antioxidants, and signaling pathways contributes to stress adaptation. The biosynthesis of melatonin in plants includes the enzymatic conversion of tryptophan. Although much is already known, future research is essential to comprehend the function of several melatonin features in sustaining plant equilibrium under environmental stresses.

西红柿作为世界主要蔬菜之一,由于环境的变化,其栽培面临着越来越大的挑战。这些挑战包括高温、干旱和盐度等非生物胁迫,这些胁迫会严重影响番茄的生长。褪黑素是一种被认为在人类睡眠周期中起作用的激素,它被认为是提高植物恢复力的潜在补救措施。这篇文章探讨了褪黑素对番茄的影响,特别是在非生物胁迫下。使用Scopus, ScienceDirect, Web of Science, PubMed和ProQuest进行全面的文献检索,确保相关科学文献的综合。本文综述了番茄中褪黑素含量因植物器官而异,并受环境因素的影响。外源褪黑素的应用已被证明在逆境条件下有益,增强抗氧化活性,光合作用和抗逆性。褪黑素在基因调控、抗氧化剂和信号通路中的作用有助于应激适应。褪黑素在植物中的生物合成包括色氨酸的酶转化。虽然已经知道了很多,但未来的研究必须了解几种褪黑素特征在维持环境胁迫下植物平衡中的功能。

Introduction: Patients in the preoperative period for coronary artery bypass grafting (CABG) frequently experience significant anxiety and depression, in addition to the physical symptoms necessitating the procedure. Preoperative health education is a crucial intervention to enhance patient knowledge, manage this psychological distress, and improve preparedness for the surgical process.

Objective: This scoping review aims to map the guidelines and strategies used for patient health education and anxiety management in the preoperative period for CABG.

Method: A scoping review was conducted in March 2024, adhering to the JBI framework. Thirteen databases were searched with no temporal or linguistic restrictions. Eligibility criteria were limited to open-access studies focused on preoperative interventions for CABG. The findings were analyzed and synthesized descriptively.

Results: The final selection included 12 studies. Key educational guidelines identified focused on surgical planning, detailed explanations of the procedure, familiarization with medical devices (e.g., drains and monitors), and postoperative care instructions. The reviewed literature consistently demonstrated that these educational interventions are effective in managing patient anxiety and are associated with a reduction in postoperative complications.

Conclusion: This review provides key guidelines for preoperative education to help clinicians reduce patient anxiety and improve surgical outcomes for those undergoing CABG.

Metabolic disorders are complex conditions that arise from abnormal biochemical reactions, disrupting normal metabolic processes. The most prevalent metabolic disorders include obesity, Type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), nonalcoholic fatty liver disease (NAFLD), and inflammatory bowel disease (IBD). Despite extensive research, no definitive therapeutic strategy has been established for a complete cure. Emerging evidence suggests that gut microbiome dysbiosis plays a critical role in the pathogenesis of these disorders, as maintaining microbial homeostasis is essential for metabolic health. Short-chain fatty acids (SCFAs) are a key metabolite produced by gut microbiota and exhibit significant therapeutic potential by serving as an energy source for colonocytes, enhancing gut barrier integrity, and modulating inflammation. Our analysis reveals that targeted microbial modulation, particularly through SCFA-producing probiotics and prebiotics, consistently benefits host metabolism and reduces systemic inflammation across multiple conditions. This review highlights the importance of gut microbiota as a viable therapeutic target and underscore the need for further clinical trials to validate microbiome-based interventions in metabolic disease management.

代谢紊乱是由异常生化反应引起的复杂疾病,破坏了正常的代谢过程。最常见的代谢性疾病包括肥胖、2型糖尿病(T2DM)、心血管疾病(CVD)、非酒精性脂肪性肝病(NAFLD)和炎症性肠病(IBD)。尽管进行了广泛的研究,但没有确定的治疗策略可以完全治愈。新出现的证据表明,肠道微生物群失调在这些疾病的发病机制中起着关键作用,因为维持微生物稳态对代谢健康至关重要。短链脂肪酸(SCFAs)是肠道微生物群产生的关键代谢物,作为结肠细胞的能量来源,增强肠道屏障完整性和调节炎症,具有重要的治疗潜力。我们的分析表明,靶向微生物调节,特别是通过产生scfa的益生菌和益生元,在多种情况下始终有利于宿主代谢并减少全身炎症。这篇综述强调了肠道微生物群作为一种可行的治疗靶点的重要性,并强调了进一步的临床试验来验证基于微生物群的代谢疾病管理干预措施的必要性。

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。
