The presence of mirror neurons (MN) in the premotor cortex, and parietal regions of the brain, has always been an area of interest to neurophysiologists, because unlike most neurons, they are activated, not only while an individual is performing an action, but also when one witnesses another experiencing a sentiment, and hence, is compelled to do the same. This phenomenon, helps develop empathy, as well as an individual's social behavior. Autism spectrum disorder (ASD) is defined as a socially isolating disease, and has been hypothesised to be caused by defective MNs. According to the World Health Organization (WHO), about 1 out of every 100 children suffer from ASD. Although many studies have proven that the impaired MN system is the underlying cause of the cognitive function defects seen in these individuals, the exact role it plays in causing the disease is still unclear.
镜像神经元(MN)存在于大脑的前运动皮层和顶叶区域,一直是神经生理学家感兴趣的领域,因为与大多数神经元不同的是,镜像神经元不仅会在一个人做出动作时被激活,而且会在一个人目睹另一个人的情感体验时被激活,从而被迫做出同样的动作。这种现象有助于培养同理心以及个人的社交行为。自闭症谱系障碍(ASD)被定义为一种与社会隔离的疾病,并被假定是由有缺陷的 MNs 引起的。根据世界卫生组织(WHO)的数据,每 100 名儿童中就有 1 人患有自闭症。尽管许多研究已经证明,MN 系统受损是导致这些人认知功能缺陷的根本原因,但它在导致这种疾病方面所起的确切作用仍不清楚。

Multiple myeloma (MM) presents a significant global health burden, with disparities in incidence and outcomes reflecting challenges in recognition and treatment. Talquetamab, a bispecific CD3 T-cell engager targeting G-protein coupled receptor family C group 5 member D (GPRC5D), has emerged as a promising immunotherapy for relapsed/refractory MM (RRMM). In August 2023, talquetamab received accelerated approval from the US FDA for RRMM treatment, followed by conditional marketing authorization from the EMA. Clinical trials demonstrated talquetamab's efficacy, with overall response rates (ORR) of 69% and 76% in heavily pretreated RRMM patients. The phase I monumenTAL-1 trial showcased talquetamab's effectiveness, particularly in high-risk MM and extramedullary disease, with ORRs around 71-74%. Subsequent phase 2 results reaffirmed its efficacy, even in patients with prior T-cell redirection therapies. Combination therapy with daratumumab further enhanced talquetamab's efficacy, addressing concerns of T cell exhaustion. Pharmacokinetic studies revealed sustained responses and manageable adverse events with subcutaneous administration, facilitating convenient dosing regimens. However, talquetamab carries risks of cytokine release syndrome (CRS) and neurologic toxicity, necessitating close monitoring and prompt management. Common adverse events included fever, CRS, musculoskeletal pain, and infections, although severe events were infrequent. Vigilant management strategies, including prophylactic measures and supportive care, mitigate these risks. In conclusion, talquetamab represents a significant advancement in RRMM treatment, offering a promising avenue for T-cell redirection therapy. Ongoing research aims to optimize treatment sequencing and combination strategies, fostering improved outcomes for MM patients. Continued investigation will refine the strategic integration of talquetamab and other immunotherapies, paving the way for enhanced treatment efficacy and patient care in RRMM.
多发性骨髓瘤(MM)给全球健康带来沉重负担,其发病率和治疗效果的差异反映了识别和治疗方面的挑战。针对G蛋白偶联受体C家族5组D(GPRC5D)的双特异性CD3 T细胞吸引剂Talquetamab已成为治疗复发/难治性MM(RRMM)的一种前景广阔的免疫疗法。2023 年 8 月,talquetamab 获得了美国 FDA 用于 RRMM 治疗的加速批准,随后又获得了 EMA 的有条件上市授权。临床试验证明了 talquetamab 的疗效,重度预处理 RRMM 患者的总反应率(ORR)分别为 69% 和 76%。monumenTAL-1一期试验显示了talquetamab的有效性,尤其是在高危MM和髓外疾病中,ORR约为71-74%。随后的二期试验结果再次证实了它的疗效,即使是既往接受过T细胞重定向疗法的患者也不例外。与达拉单抗联合治疗进一步增强了talquetamab的疗效,解决了T细胞衰竭的问题。药代动力学研究显示,皮下注射可产生持续的反应和可控的不良反应,从而方便了给药方案。不过,talquetamab 有细胞因子释放综合征(CRS)和神经系统毒性的风险,需要密切监测和及时处理。常见的不良反应包括发热、CRS、肌肉骨骼疼痛和感染,但严重的不良反应并不多见。包括预防措施和支持性护理在内的谨慎管理策略可降低这些风险。总之,talquetamab代表了RRMM治疗的一大进步,为T细胞重定向治疗提供了一条前景广阔的途径。正在进行的研究旨在优化治疗排序和组合策略,改善 MM 患者的预后。持续的研究将完善talquetamab和其他免疫疗法的战略整合,为提高RRMM的治疗效果和患者护理铺平道路。

Cardiovascular diseases (CVDs) pose a significant global health challenge, with India bearing a disproportionate burden of CVD-related morbidity and mortality. Hypertension (HTN) is a major risk factor for CVDs, affecting nearly 30% of the Indian population. Achieving target blood pressure (BP) levels is crucial for reducing cardiovascular risk, necessitating aggressive antihypertensive therapy. Combination therapy has emerged as a cornerstone in HTN management, especially in high-risk patients. This review delves into the literature and perspectives of Indian cardiologists on combination therapy for HTN management. Despite the efficacy of contemporary antihypertensive medications, a substantial proportion of patients fail to reach target BP levels with monotherapy. Combination therapy offers synergistic effects, addressing multiple pathways involved in HTN pathogenesis. Recent guidelines recommend initiating treatment with two-drug combinations, transitioning to three-drug combinations in resistant cases. Combination therapy not only enhances BP control but also reduces the risk of cardiovascular events and mortality compared to monotherapy. Optimal management of HTN requires personalized approaches, considering individual patient profiles and comorbidities such as coronary artery disease (CAD), diabetes mellitus (DM), dyslipidemia, and heart failure (HF). In such cases, combination therapy plays a pivotal role in mitigating cardiovascular risks. ARB/CCB combination therapy, particularly telmisartan/amlodipine, demonstrates significant efficacy and tolerability across various patient populations, including those with metabolic risk factors and renal impairment. Expert recommendations highlight the importance of individualized therapy, patient education, early diagnosis, and initiation with dual therapy in India. Strategies to improve medication adherence and compliance, such as single-pill double or triple combinations, are emphasized. Moreover, awareness of newer treatment options and contactless diagnostic instruments is crucial for optimizing HTN management. In conclusion, combination therapy stands as a cornerstone in HTN management, offering enhanced efficacy, tolerability, and cardiovascular protection. Tailored approaches guided by expert recommendations are essential to address the growing burden of HTN and reduce the socioeconomic impact of CVDs in India.
心血管疾病(CVDs)对全球健康构成重大挑战,而印度在心血管疾病相关的发病率和死亡率方面承受着不成比例的负担。高血压(HTN)是心血管疾病的主要风险因素,影响着近 30% 的印度人口。达到目标血压(BP)水平是降低心血管风险的关键,因此需要积极的降压治疗。联合疗法已成为高血压治疗的基石,尤其是在高危患者中。这篇综述深入探讨了印度心脏病专家对联合疗法治疗高血压的文献和观点。尽管当代降压药物疗效显著,但仍有相当一部分患者无法通过单一疗法达到目标血压水平。联合疗法具有协同作用,可解决高血压发病机制中的多种途径。最新的指南建议首先使用两药联合治疗,在耐药的情况下再过渡到三药联合治疗。与单一疗法相比,联合疗法不仅能加强血压控制,还能降低心血管事件和死亡风险。高血压的最佳治疗需要个性化的方法,考虑患者的个体情况和合并症,如冠状动脉疾病(CAD)、糖尿病(DM)、血脂异常和心力衰竭(HF)。在这种情况下,联合疗法在降低心血管风险方面发挥着关键作用。ARB/CCB联合疗法,尤其是替米沙坦/氨氯地平,在不同的患者群体(包括有代谢风险因素和肾功能损害的患者)中显示出显著的疗效和耐受性。专家建议在印度强调个体化治疗、患者教育、早期诊断和开始双重疗法的重要性。专家还强调了提高用药依从性和依从性的策略,如单药双联或三联疗法。此外,了解更新的治疗方案和非接触式诊断仪器对于优化高血压管理至关重要。总之,联合疗法是高血压管理的基石,可提高疗效、耐受性和心血管保护。专家建议指导下的定制方法对于解决印度日益增长的高血压负担和减少心血管疾病的社会经济影响至关重要。

Background: There are different types of exam formats for educational assessment. Multiple choice questions (MCQs) are frequently utilized assessment tools in health education. Considering the reliability and validity in developing MCQ items is vital. Educators often face the difficulty of developing credible distractors in MCQ items. Poorly constructed MCQ items make an exam easier or too difficult to be answered correctly by students as intended learning objectives. Checking the quality of MCQ items is overlooked and too little is known about it. Therefore, this study aimed to assess the quality of MCQ items using the item response theory model. Methods: A descriptive cross-sectional study was conducted among MCQ items of public health courses administered to 2nd year nursing students at Injibara university. A total of 50 MCQ items and 200 alternatives were evaluated for statistical item analysis. The quality of MCQ items was assessed by difficulty index (DIF), discrimination index (DI), and distractor efficiency (DE) using students’ exam responses. Microsoft excel sheet and SPSS version 26 were used for data management and analysis. Results: Post-exam item analysis showed that 11 (22%) and 22 (44%) MCQs had too difficult and poor ranges for difficulty and discriminating powers respectively. The overall DE was 71.3%. About forty (20%) distractors were non-functional. Only 8 (16%) MCQs fulfilled the recommended criteria for all-DIF, DI, and DE parameters. Conclusions: The desirable criteria for quality parameters of MCQ items were satisfied only in a few items. The result implies the need for quality improvement. Continuous trainings are required to improve the instructors’ skills to construct quality educational assessment tools.
背景:教育评估有不同类型的考试形式。多项选择题(MCQ)是健康教育中经常使用的评估工具。在开发 MCQ 题目时,对信度和效度的考虑至关重要。教育工作者通常面临的困难是如何在 MCQ 题目中开发可信的干扰项。构造不良的 MCQ 题项会使考试变得过于简单或过于困难,从而使学生无法按照预期的学习目标正确作答。检查 MCQ 项目的质量被忽视了,而且人们对此知之甚少。因此,本研究旨在利用项目反应理论模型评估 MCQ 项目的质量。研究方法对仁吉巴拉大学护理专业二年级学生公共卫生课程的 MCQ 项目进行了描述性横断面研究。共评估了 50 个 MCQ 项目和 200 个备选项目,并进行了项目统计分析。利用学生的考试答卷,通过难度指数(DIF)、区分度指数(DI)和分心效率(DE)来评估 MCQ 项目的质量。数据管理和分析使用了 Microsoft excel 表格和 SPSS 26 版本。结果考后项目分析显示,分别有 11 道(22%)和 22 道(44%)单项选择题的难度和区分度范围过大和过小。总体得分率为 71.3%。约有 40 个(20%)干扰项不起作用。只有 8 道(16%)单项智力题符合所有 DIF、DI 和 DE 参数的建议标准。结论只有少数题目符合 MCQ 质量参数的理想标准。这一结果表明有必要改进质量。需要持续开展培训,以提高教师构建高质量教育评估工具的技能。

Traumatic brain injury (TBI) remains a significant public health concern worldwide, necessitating effective research models to elucidate its pathophysiology and develop therapeutic interventions. Animal models play a crucial role in TBI research, offering valuable insights into injury mechanisms and potential treatments. However, selecting the appropriate model can be challenging due to diverse array of available options and their respective advantages and limitations. In this comprehensive review, we examine four commonly used animal models of TBI: the weight drop, fluid percussion, cortical impact, and blast injury models. Each model is characterized by distinct injury mechanisms, allowing researchers simulate various aspects of TBI pathology. We discuss the unique advantages and disadvantages of each model, providing insights into their applications and considerations for model selection based on research objectives and outcome measures. Furthermore, we highlight emerging directions in TBI modelling, emphasizing the importance of refining and innovating models to replicate the complexity of human TBI. By critically evaluating and understanding the subtlety of different TBI models, researchers can make informed decisions to enhance the translational potential of preclinical TBI research and ultimately improve clinical outcomes for TBI patients.
创伤性脑损伤(TBI)仍然是全球关注的一个重大公共卫生问题,需要有效的研究模型来阐明其病理生理学并开发治疗干预措施。动物模型在创伤性脑损伤研究中发挥着至关重要的作用,可为损伤机制和潜在治疗方法提供宝贵的见解。然而,由于可供选择的模型种类繁多,且各自存在优势和局限性,因此选择合适的模型可能具有挑战性。在这篇综述中,我们研究了四种常用的创伤性脑损伤动物模型:重物下坠模型、流体叩击模型、皮层冲击模型和爆炸损伤模型。每种模型都具有不同的损伤机制,使研究人员能够模拟创伤性脑损伤病理的各个方面。我们讨论了每种模型的独特优缺点,深入探讨了它们的应用以及根据研究目标和结果衡量标准选择模型的注意事项。此外,我们还强调了创伤性脑损伤建模的新方向,强调了完善和创新模型以复制人类创伤性脑损伤复杂性的重要性。通过批判性地评估和理解不同创伤性脑损伤模型的微妙之处,研究人员可以做出明智的决定,以提高创伤性脑损伤临床前研究的转化潜力,并最终改善创伤性脑损伤患者的临床治疗效果。

Antibiotic abuses and overuses are factors in the global issue of antibiotic resistance (ABR) which is becoming more acute in densely populated urban areas. To offer a concise summary of the present status of ABR in Pabna city, identify any deficiencies and generate recommendations based on findings, a comprehensive analysis was performed. We conducted a search for articles related to ABR published between 2003 to 2022 using search engines such as Google Scholar, PubMed, online and offline journals in Bangladesh. In the past, it was possible to determine the median and interquartile ranges of an organism’s ABR. Forty-two research articles were included in this review. For determining antibiotic susceptibility, approximately 95.96% of the investigations used the disk diffusion method, and about 91.98% followed the clinic and laboratory standards institute’s recommendations. However, information about susceptibility testing procedures and the source of infections-whether they were hospital-based or community-based-was conspicuously absent from about 11.19%, 12.62%, and 92.24% of the study studies, respectively. Many of the diseases studied exhibited high levels of resistance, and traditional first-line antibiotics were largely ineffective. Most of the patients displayed only mild resistance to carbapenem. A developing trend in ABR across the majority of antibiotic classes was also revealed by our findings, in addition to severe monitoring and informational gaps.
抗生素滥用和过度使用是导致全球抗生素耐药性(ABR)问题的因素之一,而在人口稠密的城市地区,抗生素耐药性问题正变得越来越严重。为了简明扼要地总结巴卜纳市的抗生素耐药性现状,找出不足之处,并根据分析结果提出建议,我们进行了一项综合分析。我们使用 Google Scholar、PubMed、孟加拉国在线和离线期刊等搜索引擎搜索了 2003 年至 2022 年间发表的与 ABR 相关的文章。过去,可以确定生物 ABR 的中位数和四分位数间范围。本综述包括 42 篇研究文章。在确定抗生素药敏性方面,约 95.96% 的调查使用了盘扩散法,约 91.98% 遵循了诊所和实验室标准研究所的建议。然而,分别约有 11.19%、12.62% 和 92.24%的研究明显缺乏有关药敏试验程序和感染来源(无论是医院感染还是社区感染)的信息。所研究的许多疾病都表现出较高的耐药性,传统的一线抗生素大多无效。大多数患者对碳青霉烯类仅表现出轻微的耐药性。除了存在严重的监测和信息缺口外,我们的研究结果还揭示了大多数抗生素类别的 ABR 发展趋势。

In the past, it was possible to determine the median and interquartile ranges of an organism’s ABR. Forty-two research articles were included in this review. For determining antibiotic susceptibility, approximately 95.96% of the investigations used the disk diffusion method, and about 91.98% followed the clinic and laboratory standards institute’s recommendations. However, information about susceptibility testing procedures and the source of infections-whether they were hospital-based or community-based-was conspicuously absent from about 11.19%, 12.62%, and 92.24% of the study studies, respectively. Many of the diseases studied exhibited high levels of resistance, and traditional first-line antibiotics were largely ineffective. Most of the patients displayed only mild resistance to carbapenem. A developing trend in ABR across the majority of antibiotic classes was also revealed by our findings, in addition to severe monitoring and informational gaps.","PeriodicalId":14297,"journal":{"name":"International Journal of Scientific Reports","volume":"35 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140663254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Good nutrition knowledge is a modifiable determinant of dietary behaviours and contributes to strengthen the skills and abilities needed to resist the environmental influences leading to poor dietary habits among adolescents. Objectives were to assess the nutrition knowledge of in-school adolescents in Sokoto, Nigeria and associated factors. Methods: A cross-sectional survey of adolescents selected through multistage random sampling. Data was obtained using pre-tested semi-structured interviewer administered questionnaire. Data was analyzed using IBM® SPSS version 25. Results: A total of 389 subjects were recruited with a mean age of 15.46±1.67 SD and most of them 231 (59.4%) were females. Most 300 (77.1%) of the participants were Hausa, 350 (90%) were Muslims, 278 (71.5%) were from the senior class, and majority 360 (92.5%) resided in urban areas. A large proportion 312 (80.2%) of the participants had good knowledge about classes of food. Only 40 (10.3%) had good knowledge of energy rich food. Two hundred and ninety-eight (76.6%) and 89 (22.9%) had knowledge on high protein diet and good fat diet respectively. Only 107 (27.5%) had good knowledge on minerals and vitamins that are good for bone development. Majority 317 (81.5%) and 341 (87.7%) of the respondents knew eating balanced diet is important and could prevent diseases, respectively. Age category (p=0.007) was the only factor that predicted nutrition knowledge. The main source of nutrition information of the adolescents was teachers 336 (86.4%). Conclusions: Respondents had good knowledge of classes of food. There is however, the need to emphasize on teaching adolescents in the study area about specific nutrient providing meals such as energy rich food, good fat, minerals and vitamins.
背景:良好的营养知识是饮食行为的一个可改变的决定因素,有助于增强青少年抵御导致不良饮食习惯的环境影响所需的技能和能力。目的:评估尼日利亚索科托在校青少年的营养知识及其相关因素。方法通过多阶段随机抽样对青少年进行横断面调查。采用预先测试的半结构式访谈问卷获取数据。数据使用 IBM® SPSS 25 版本进行分析。结果共招募了 389 名受试者,平均年龄(15.46±1.67 SD)岁,其中 231 人(59.4%)为女性。大多数受试者 300 人(77.1%)是豪萨人,350 人(90%)是穆斯林,278 人(71.5%)来自高年级,大多数 360 人(92.5%)居住在城市地区。大部分 312 名(80.2%)参与者对食物种类有很好的了解。只有 40 人(10.3%)对富含能量的食物有所了解。分别有 298 人(76.6%)和 89 人(22.9%)了解高蛋白饮食和高脂肪饮食。只有 107 人(27.5%)了解有利于骨骼发育的矿物质和维生素。317(81.5%)和 341(87.7%)的受访者知道均衡饮食很重要,并能预防疾病。年龄(p=0.007)是唯一能预测营养知识的因素。青少年营养信息的主要来源是教师 336 人(86.4%)。结论受访者对食物种类有较好的了解。然而,有必要强调向研究地区的青少年传授有关提供特定营养的膳食知识,如富含能量的食物、优质脂肪、矿物质和维生素。

Empty Sella syndrome (ESS) pertains to a phenomenon in which the Turkish sale seems through radiography to be larger and perhaps partially or entirely filled with brain fluids. It can be major illness/ develop as a result of pituitary medical procedures, radiation therapy cerebral infarction/bleeding process. A 50 years old female patient was admitted in emergency medicine ward with chief complaint of pain in abdomen, weakness and vomiting. MRI scan of pituitary cerebrospinal fluid (CSF) signal intensity is seen in Sella with no visible anterior pituitary gland tissue noted-likely suggestive of secondary empty Sella (SES). Long-term steroid use is principal therapy for adrenocorticotropic hormone deficiency (IAD). In this instance, ESS, which can be primary/secondary, also noticed.

Background: Husbands’ support in obstetric care services is a process of social and behavioral change that husbands must undergo to prevent obstetric complications. But so far, studies across Ethiopia have been inconsistent and lacking in the study area. Therefore, this study was aimed at assessing husbands’ predictors, which could help in interventions. Methods: A community-based cross-sectional study was conducted in the Dire Dawa administration, Ethiopia, from July 1-30, 2022. Participants were selected using a systematic sampling technique. Data were collected through interviews using a structured questionnaire, entered into EPI data (Version 3.1), and analyzed using SPSS (Version 22). A p=0.05 or less at multivariate with 95% confidence intervals was considered statistically significant. Results: Of a total of 610, 51.8% of husbands support wives in using obstetrics care services. The predictors were urban residence (AOR=2.55, 95% CI: 1.75-3.73), education level of diploma and above (AOR=2.00, 95%CI: 1.10-3.74), perceived importance (AOR=1.98, 95% CI: 1.30-3.00), antenatal care visit accompanying experience (AOR=1.79, 95% CI: 1.04-3.07), and institutional delivery accompanying experience (AOR=6.20, 95% CI: 3.4-1.33). Conclusions: One in two husbands supports wives to use obstetrics care services provided by health professionals. Findings are helpful in advancing knowledge of husbands’ factors and highlight the need for health facilities and stakeholders to strengthen and create continuous community awareness.
背景:丈夫对产科护理服务的支持是预防产科并发症所必须经历的社会和行为改变过程。但迄今为止,埃塞俄比亚各地的研究并不一致,也缺乏研究领域。因此,本研究旨在评估丈夫的预测因素,以帮助采取干预措施。研究方法2022 年 7 月 1 日至 30 日,在埃塞俄比亚迪雷达瓦行政区开展了一项基于社区的横断面研究。研究采用系统抽样技术选取参与者。使用结构化问卷通过访谈收集数据,输入 EPI 数据(3.1 版),并使用 SPSS(22 版)进行分析。在95%置信区间的多元变量中,P=0.05或更小被认为具有统计学意义。结果在总共 610 人中,51.8% 的丈夫支持妻子使用产科护理服务。预测因素为城市居住地(AOR=2.55,95% CI:1.75-3.73)、文凭及以上教育程度(AOR=2.00,95%CI:1.10-3.74)、重要性感知(AOR=1.98,95% CI:1.30-3.00)、产前护理访视陪同经验(AOR=1.79,95% CI:1.04-3.07)和住院分娩陪同经验(AOR=6.20,95% CI:3.4-1.33)。结论每两位丈夫中就有一位支持妻子使用医疗专业人员提供的产科护理服务。研究结果有助于加深对丈夫因素的了解,并强调医疗机构和利益相关者有必要加强并不断提高社区意识。

Background: Anthropogenic activities release cadmium (Cd), nickel (Ni), and other heavy metals into soil. Zea mays can clean up contaminated soils, but little is known about how Cd and Ni co-contamination stress affects ethylenediamine tetraacetic acid (EDTA)-based phytoextraction and phytoremediation, hence this study was conducted.Methods: The experiment involved nine treatment levels (0, 5, 10, 15, and 20 mg kg-1 Cd and 0, 15, 30, 45, and 60 mg kg-1 Ni), grouped into three categories: CT as the control group, P as Cd + Ni only, and CAP as Cd + Ni + EDTA (n=3). The treatments used (CH3COO)2Cd•2H2O and NiSO4 as the source of Cd and Ni, respectively, and EDTA was applied at two rates (0 and 0.5 g/kg). After the experimental period, measurements were taken for shoot length, biomass, and metal concentrations in both the roots and shoots using established procedures.  Results: The concentrations of metals in plants' roots and shoots increased as the concentrations in soil increased, but shoot length, biomass, bioconcentration factor (BCF), and translocation factor (TF) values decreased with increasing soil metal content. The application of EDTA increased metal uptake but led to greater root and shoot biomass loss. Generally, TF values for Cd and Ni were less than 1 but most of the BCF values were greater than 1.Conclusions: The study found that phytostabilization is the main mechanism for phytoremediation of Cd-Ni-co-contaminated soils with Zea mays, with EDTA addition enhancing metal accumulation and reducing biomass yield.
背景:人类活动会向土壤中释放镉(Cd)、镍(Ni)和其他重金属。玉米可以净化受污染的土壤,但人们对镉和镍共污染胁迫如何影响基于乙二胺四乙酸(EDTA)的植物萃取和植物修复知之甚少,因此开展了这项研究:实验涉及九个处理水平(0、5、10、15 和 20 mg kg-1 Cd 和 0、15、30、45 和 60 mg kg-1 Ni),分为三类:CT 为对照组,P 仅为 Cd + Ni,CAP 为 Cd + Ni + EDTA(n=3)。处理分别使用 (CH3COO)2Cd-2H2O 和 NiSO4 作为镉和镍的来源,乙二胺四乙酸的施用量为两种(0 和 0.5 克/千克)。实验结束后,按照既定程序测量了芽的长度、生物量以及根和芽中的金属浓度。 实验结果植物根部和嫩枝中的金属浓度随着土壤中金属浓度的增加而增加,但嫩枝长度、生物量、生物富集因子(BCF)和易位因子(TF)值随着土壤中金属含量的增加而减少。施用乙二胺四乙酸(EDTA)增加了对金属的吸收,但导致根和芽的生物量损失更大。一般来说,镉和镍的 TF 值小于 1,但大多数 BCF 值大于 1.结论:研究发现,植物稳定化是玉米对镉镍共污染土壤进行植物修复的主要机制,添加乙二胺四乙酸会增加金属积累,降低生物量产量。
