    目的:这项研究的目的是确定经皮神经电刺激(TENS)对疼痛的影响,功能,生活质量,和TKR患者的镇痛药消耗。
    方法:单中心,随机对照试验。
    方法:共有52名参与者被随机分为干预组(n=26)和对照组(n=26)。干预组暴露于常规TENS。使用患者识别表收集数据,视觉模拟量表(VAS),西安大略省和麦克马斯特大学骨关节炎指数(WOMAC),生活质量量表(SF-36),和镇痛追踪表。
    结果:干预组VAS和WOMAC评分明显下降,随着时间的推移,而对照组则增加。随着时间的推移,干预组的SF-36得分显着增加。确定干预组的镇痛药消耗量明显低于对照组。
    结论:TENS显著减轻疼痛,提高功能和生活质量。我们的研究结果表明,TENS可能是接受TKR的患者的有效辅助镇痛治疗;然而,在更大和更异质的群体中需要更多的测试。
    结论:护士可以为TKR患者提供有效的术后疼痛控制,增加功能,加速愈合过程,通过使用TENS来提高他们的生活质量,非药物治疗方法,在围手术期。
    OBJECTIVE: The aim of this study was to determine the effect of transcutaneous electrical nerve stimulation (TENS) on pain, functionality, quality of life, and analgesic consumption in patients undergoing TKR.
    METHODS: A single center, randomized controlled trial.
    METHODS: A total of 52 participants were randomly assigned to the intervention (n = 26) and control (n = 26) groups. The intervention group was exposed to conventional TENS. Data were collected with a Patient Identification Form, the Visual Analogue Scale (VAS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Quality of Life Scale (SF-36), and the Analgesic Tracking Form.
    RESULTS: VAS and WOMAC scores significantly decreased in the intervention group, over time, while they increased in the control group. SF-36 scores significantly increased in the intervention group over time. It was determined that analgesic consumption was significantly lower in the intervention group than in the control group.
    CONCLUSIONS: TENS significantly reduced pain and increased functionality and quality of life. Our findings suggest that TENS may be an effective adjunctive analgesic therapy in patients receiving TKR; however, more testing is needed in larger and more heterogeneous populations.
    CONCLUSIONS: Nurses can provide effective postoperative pain control in patients undergoing TKR, increase functionality, accelerate the healing process, and improve their quality of life by using TENS, a non-pharmacological treatment method, in the perioperative period.

    工作场所健康管理(WHM)对公司来说是一项值得投资的投资。然而,促进健康的干预措施的实施仍然有限,特别是中小企业。组织间网络可能是提高对实施WHM优势的认识的一种有希望的方法。因此,本研究的目的是从公司的角度分析区域WHM网络的感知功能和好处,并提出关于这一特定主题的初步结果。
    进行了探索性定性案例研究,分析了ERZgesund,德国农村地区的WHM网络。对参加该网络的22家公司进行了采访,了解了他们参加WHM网络ERZgesund的经验以及所感知的优缺点。
    调查结果表明,该网络提高了公司对WHM的认识,提供交流知识和经验的机会,并产生或加强合作。网络的结构增强了积极的影响,例如区域性和直接联系人。然而,一些公司表示,他们欢迎更高水平的参与和透明度。
    总的来说,很明显,WHM网络可以成为强调WHM与公司相关性的宝贵工具。因此,进一步的研究应验证和加强对WHM网络的研究,以确保网络的长期利益。
    UNASSIGNED: Workplace health management (WHM) is a worthwhile investment for companies. Nevertheless, the implementation of health-promoting interventions remains limited, especially in small and medium-sized enterprises. Interorganisational networks could be a promising way to raise awareness of the advantages of implementing WHM. Therefore, the aim of this study is to analyse the perceived functionality and benefits of a regional WHM network from companies\' perspective and to present initial results on this specific topic.
    UNASSIGNED: An explorative qualitative case study was conducted analysing ERZgesund, a WHM network in a rural region in Germany. Twenty-two companies that participated in the network were interviewed about their experiences and perceived advantages and disadvantages participating in the WHM network ERZgesund.
    UNASSIGNED: The findings show that the network has raised awareness about WHM among the companies, provides opportunities for exchange of knowledge and experiences, and generates or strengthens collaboration. The positive effects were enhanced by the network\'s structure, such as regionality and a direct contact person. Nevertheless, some companies stated that they would welcome a higher level of participation and transparency.
    UNASSIGNED: Overall, it becomes clear that a WHM network can be a valuable tool to emphasize the relevance of WHM to companies. Therefore, further studies should validate and intensify the research on WHM networks to ensure a long-term benefit from the network.

    米粒被广泛用作主食,为家庭提供必要的营养,尤其是边缘化家庭。它在确保粮食安全方面发挥着至关重要的作用,促进人类营养,支持良好的健康,促进全球粮食和营养安全。为了解决新兴的多样化和气候风险人群饮食需求的多样化质量需求,需要开发能够满足各种饮食和营养需求的单一品种稻米。然而,稻米品质缺乏具体定义,使它具有挑战性,以满足不同的需求。在改善稻米品质方面缺乏足够的遗传研究和开发,导致普遍营养不良,隐藏的饥饿,和微量营养素缺乏影响全球人口的很大一部分。因此,至关重要的是,确定具有显著品质的基因进化品种,可以帮助解决这些问题。各种因素导致稻米品质下降,需要进一步研究以提高其品质,以获得更健康的饮食。我们使用Lancastrians描述符和许多内在和外在品质性状表征了稻米的品质。接下来,我们研究了亚太地区稻米品质的各种成分。这包括不同社区的偏好,水稻产业利益相关者,和价值链参与者。我们还探索了该地区稻米品质的生物学方面,以及在这些特征中进行的特定遗传改进。此外,我们评估了影响稻米品质的因素,并讨论了确保粮食和营养安全以及满足消费者对谷物品质需求的未来方向。我们探索了包括印度在内的亚太国家不同的消费者基础和他们不同的偏好,中国,尼泊尔,不丹,越南,斯里兰卡,巴基斯坦,泰国,柬埔寨,菲律宾,孟加拉国,印度尼西亚,韩国,缅甸和日本。质量偏好包含一系列因素,包括米头恢复,颗粒形状,烹饪前的均匀尺寸,糊化,白垩,纹理,直链淀粉含量,香气,谷物的红色,煮熟时柔软闪亮,煮熟时不间断,糊化,做饭需要更少的水,糊化温度(较少的烹饪时间),陈年大米,煮熟时坚硬干燥(凝胶稠度),极端的白色,咀嚼时柔软,易于烹饪的米饭(煮米饭),维生素,和矿物。这些偏好被评估得很高,低,中等类别。对提高籽粒品质性状进行了综合分析,包括糙米的恢复,精米的回收率,头部大米恢复,以及粒长等形态特征,晶粒宽度,晶粒长宽比,和谷物白垩。我们还探索了直链淀粉的特性,凝胶稠度,糊化温度,粘度,以及米粒的营养品质,如淀粉,蛋白质,脂质,维生素,矿物,植物化学物质,和生物强化潜力。影响米粒品质的各种因素,包括收获前,收获后,和基因型考虑因素进行了探讨。此外,我们讨论了有效应对这些挑战的未来方向和遗传策略。这些定性特征代表了不同国家为满足消费者偏好而采用的区域和国家育种策略的基本重点。鉴于大米作为亚太国家主食的重要性,它主要在国内消费,只有一小部分出口到国际上。所有重要的属性必须在特定参数中明确定义。对于遗传学家和育种者来说,开发一种水稻品种至关重要,该品种可以通过结合多种理想性状来满足全球消费者的多种需求。因此,解决全球粮食和营养安全的目标,人类的健康是可以实现的。
    Rice grain is widely consumed as a staple food, providing essential nutrition for households, particularly marginalized families. It plays a crucial role in ensuring food security, promoting human nutrition, supporting good health, and contributing to global food and nutritional security. Addressing the diverse quality demands of emerging diverse and climate-risked population dietary needs requires the development of a single variety of rice grain that can meet the various dietary and nutritional requirements. However, there is a lack of concrete definition for rice grain quality, making it challenging to cater to the different demands. The lack of sufficient genetic study and development in improving rice grain quality has resulted in widespread malnutrition, hidden hunger, and micronutrient deficiencies affecting a significant portion of the global population. Therefore, it is crucial to identify genetically evolved varieties with marked qualities that can help address these issues. Various factors account for the declining quality of rice grain and requires further study to improve their quality for healthier diets. We characterized rice grain quality using Lancastrians descriptor and a multitude of intrinsic and extrinsic quality traits. Next, we examined various components of rice grain quality favored in the Asia-Pacific region. This includes preferences by different communities, rice industry stakeholders, and value chain actors. We also explored the biological aspects of rice grain quality in the region, as well as specific genetic improvements that have been made in these traits. Additionally, we evaluated the factors that can influence rice grain quality and discussed the future directions for ensuring food and nutritional security and meeting consumer demands for grain quality. We explored the diverse consumer bases and their varied preferences in Asian-Pacific countries including India, China, Nepal, Bhutan, Vietnam, Sri Lanka, Pakistan, Thailand, Cambodia, Philippines, Bangladesh, Indonesia, Korea, Myanmar and Japan. The quality preferences encompassed a range of factors, including rice head recovery, grain shape, uniform size before cooking, gelatinization, chalkiness, texture, amylose content, aroma, red-coloration of grain, soft and shine when cooked, unbroken when cooked, gelatinization, less water required for cooking, gelatinization temperature (less cooking time), aged rice, firm and dry when cooked (gel consistency), extreme white, soft when chewed, easy-to-cook rice (parboiled rice), vitamins, and minerals. These preferences were evaluated across high, low, and medium categories. A comprehensive analysis is provided on the enhancement of grain quality traits, including brown rice recovery, recovery rate of milled rice, head rice recovery, as well as morphological traits such as grain length, grain width, grain length-width ratio, and grain chalkiness. We also explored the characteristics of amylose, gel consistency, gelatinization temperature, viscosity, as well as the nutritional qualities of rice grains such as starch, protein, lipids, vitamins, minerals, phytochemicals, and bio-fortification potential. The various factors that impact the quality of rice grains, including pre-harvest, post-harvest, and genotype considerations were explored. Additionally, we discussed the future direction and genetic strategies to effectively tackle these challenges. These qualitative characteristics represent the fundamental focus of regional and national breeding strategies employed by different countries to meet consumer preference. Given the significance of rice as a staple food in Asia-Pacific countries, it is primarily consumed domestically, with only a small portion being exported internationally. All the important attributes must be clearly defined within specific parameters. It is crucial for geneticists and breeders to develop a rice variety that can meet the diverse demands of consumers worldwide by incorporating multiple desirable traits. Thus, the goal of addressing global food and nutritional security, and human healthy can be achieved.

    背景:俯卧的脚姿势对姿势稳定性有负面影响,函数,和膝盖外翻,但就我们所知,尚未检查内旋程度的贡献。
    方法:纳入39名年龄在18-40岁之间的参与者,足部姿势指数(FPI)评分在6-12之间,没有任何疼痛抱怨。6-9分的参与者被纳入内旋组(PG)(n=19),和10-12分的参与者被纳入超前组(HPG)(n=20).静态和动态姿势稳定性,脚和脚踝能力测量(FAAM),测量所有参与者的额平面投影角度(FPPA)。
    结果:参与者的初始数据是均匀分布的。在组间评估中,只有FPI-1(p=0.001;p<0.05),FPI-4(p=0.00;p<0.05),FPI-5(p=0.00;p<0.05)和FPI-T(p=0.000;p<0.05)评分差异显著。
    结论:距下关节的发音和超前没有导致姿势稳定性的差异,函数,和健康个体的膝盖外翻。专注于俯卧姿势而不是内旋程度可能更有益。
    BACKGROUND: The prone foot posture has a negative effect on postural stability, function, and knee valgus, but to our knowledge, the contribution of the degree of pronation has not been examined.
    METHODS: 39 participants aged 18-40, with Foot Posture Index (FPI) scores between 6-12 and without any pain complaints were included. Participants with 6-9 points were included in the pronation group (PG) (n = 19), and participants with 10-12 points were included in the hyperpronation group (HPG) (n = 20). Static and dynamic postural stability, Foot and Ankle Ability Measure (FAAM), and frontal plane projection angles (FPPA) were measured for all participants.
    RESULTS: The initial data of the participants are distributed homogeneously. In the intergroup evaluation only FPI-1 (p = 0.001; p < 0.05), FPI-4 (p = 0.00; p < 0.05), FPI-5 (p = 0.00; p < 0.05) and FPI-T (p = 0.000; p < 0.05) scores were found significantly different.
    CONCLUSIONS: Pronation and hyperpronation of the subtalar joint did not lead to a difference in postural stability, function, and knee valgus in healthy individuals. It may be more beneficial to focus on the prone posture rather than the degree of pronation.

    大豆蛋白是一种有前途的营养来源,由于与多酚(PP)结合而具有改善的功能和生物活性-大豆蛋白和PP之间的缀合物通过共价键和非共价键保持。不同的方法,包括热力学,光谱学,和分子对接模拟,可以证明这些缀合物的结果和机制。大豆蛋白,PP结构,基体属性(温度,pH值),相互作用机制改变ζ电位,二级结构,热稳定性,和蛋白质的表面疏水性,还提高了技术功能特性,如胶凝能力,溶解度,乳化,和发泡性能。大豆蛋白-PP缀合物还显示出增强的体外消化率,抗过敏,抗氧化剂,抗癌,抗炎,和抗菌活性。因此,这些缀合物可以用作可食用薄膜添加剂,抗氧化剂乳化剂,水凝胶,和食品工业中的纳米颗粒。需要进一步的研究来指定大豆蛋白-PP缀合物的结构-功能关联,这可能会影响其功能和在食品工业中的应用。
    Soy protein is a promising nutritional source with improved functionality and bioactivities due to conjugation with polyphenols (PP)-the conjugates between soy protein and PP held by covalent and noncovalent bonds. Different approaches, including thermodynamics, spectroscopy, and molecular docking simulations, can demonstrate the outcomes and mechanism of these conjugates. The soy protein, PP structure, matrix properties (temperature, pH), and interaction mechanism alter the ζ-potential, secondary structure, thermal stability, and surface hydrophobicity of proteins and also improve the techno-functional properties such as gelling ability, solubility, emulsifying, and foaming properties. Soy protein-PP conjugates also reveal enhanced in vitro digestibility, anti-allergic, antioxidant, anticancer, anti-inflammatory, and antimicrobial activities. Thus, these conjugates may be employed as edible film additives, antioxidant emulsifiers, hydrogels, and nanoparticles in the food industry. Future research is needed to specify the structure-function associations of soy protein-PP conjugates that may affect their functionality and application in the food industry.

    (1)背景:恢复手臂和手功能是颈脊髓损伤(cSCI)患者的优先事项之一。无创电磁神经调节是目前的一种方法,旨在改善SCI患者的上肢功能。这项研究的目的是回顾有关非侵入性电磁神经调节技术的不同应用的最新信息,这些技术专注于恢复cSCI患者的上肢功能和运动功能。(2)方法:采用系统评价和Meta分析(PRISMA)指南的首选报告项目构建检索方案。在三个数据库中对文献进行了系统的回顾:Cochrane图书馆,PubMed,和物理治疗证据数据库(PEDro)。(3)结果:共纳入25项研究,其中4项是经颅磁刺激(TMS),四对经颅直流电刺激(TDCS),两个经皮脊髓刺激(tSCS),功能电刺激(FES)四个经皮神经电刺激(TENS),和一个神经肌肉刺激(NMS)。由于缺乏共同的运动或功能评估,无法完成荟萃分析。最后,我们实现了对结果的叙述性回顾,该研究报告,在cSCI受试者中,非侵入性电磁神经调节联合脑或脊髓水平的康复治疗显著改善了上肢功能和运动功能.结果与对照组相比,tSCS时,FES,TENS,并应用了NMS。(4)结论:为了进行荟萃分析并提供更多证据,需要对cSCI上肢进行标准化结局测量的随机对照试验,尽管在每项非侵入性电磁神经调节研究中都有显著改善.
    (1) Background: Restoring arm and hand function is one of the priorities of people with cervical spinal cord injury (cSCI). Noninvasive electromagnetic neuromodulation is a current approach that aims to improve upper-limb function in individuals with SCI. The aim of this study is to review updated information on the different applications of noninvasive electromagnetic neuromodulation techniques that focus on restoring upper-limb functionality and motor function in people with cSCI. (2) Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were used to structure the search protocol. A systematic review of the literature was performed in three databases: the Cochrane Library, PubMed, and Physiotherapy Evidence Database (PEDro). (3) Results: Twenty-five studies were included: four were on transcranial magnetic stimulation (TMS), four on transcranial direct current stimulation (tDCS), two on transcutaneous spinal cord stimulation (tSCS), ten on functional electrical stimulation (FES), four on transcutaneous electrical nerve stimulation (TENS), and one on neuromuscular stimulation (NMS). The meta-analysis could not be completed due to a lack of common motor or functional evaluations. Finally, we realized a narrative review of the results, which reported that noninvasive electromagnetic neuromodulation combined with rehabilitation at the cerebral or spinal cord level significantly improved upper-limb functionality and motor function in cSCI subjects. Results were significant compared with the control group when tSCS, FES, TENS, and NMS was applied. (4) Conclusions: To perform a meta-analysis and contribute to more evidence, randomized controlled trials with standardized outcome measures for the upper extremities in cSCI are needed, even though significant improvement was reported in each non-invasive electromagnetic neuromodulation study.

    绿豆生长过程中硒(Se)的生物强化是提高硒含量和品质的有效方法。然而,硒生物强化对绿豆蛋白理化性质的影响尚不清楚。这项研究的目的是澄清成分的变化,Se形式,颗粒结构,功能属性,热稳定性,在四个硒施用水平下绿豆蛋白的凝胶特性。结果表明,绿豆蛋白中硒含量呈剂量依赖性增加,在最高浓度下增加7.96倍(P1)和8.52倍(P2)。外源Se的应用促进了无机Se向有机Se的转化。其中,硒代蛋氨酸(SeMet)和甲基硒代半胱氨酸(MeSeCys)通过S代谢途径取代了Met和Cys,成为富硒绿豆蛋白中的主要有机Se形式,占总硒含量的80%以上。在SeMet和MeSeCys含量增加的情况下,30g/hm2的外源硒显着上调了蛋白质含量,并促进了含硫蛋白质成分和疏水性氨基酸的合成。同时,Cys和Met取代改变了巯基(SH),β-sheets,和蛋白质的β转角。粒径和微观结构特征取决于蛋白质本身,不受外源Se的影响。Se诱导的疏水性氨基酸和β-折叠的含量增加协同增加了蛋白质的热稳定性。适度施硒改变了绿豆蛋白的功能特性,主要体现在持油能力(OHC)和发泡能力(FC)的显著提高。此外,外源硒诱导的SH和β-折叠的增加可以改变蛋白质分子间网络,有助于增加储能模量(G\')和损耗模量(G”),这导致形成了更高弹性的凝胶。本研究进一步促进了绿豆蛋白在食品加工领域的应用,为富硒绿豆蛋白的广泛开发提供了理论依据。
    Selenium (Se) biofortification during the growth process of mung bean is an effective method to improve the Se content and quality. However, the effect of Se biofortification on the physicochemical properties of mung bean protein is unclear. The objective of this study was to clarify the changes in the composition, Se forms, particle structure, functional properties, thermal stability, and gel properties of mung bean protein at four Se application levels. The results showed that the Se content of mung bean protein increased in a dose-dependent manner, with 7.96-fold (P1) and 8.52-fold (P2) enhancement at the highest concentration. Exogenous Se application promotes the conversion of inorganic Se to organic Se. Among them, selenomethionine (SeMet) and methyl selenocysteine (MeSeCys) replaced Met and Cys through the S metabolic pathway and became the dominant organic Se forms in Se-enriched mung bean protein, accounting for more than 80 % of the total Se content. Exogenous Se at 30 g/hm2 significantly up-regulated protein content and promoted the synthesis of sulfur-containing protein components and hydrophobic amino acids in the presence of increased levels of SeMet and MeSeCys. Meanwhile, Cys and Met substitution altered the sulfhydryl groups (SH), β-sheets, and β-turns of protein. The particle size and microstructural characteristics depend on the protein itself and were not affected by exogenous Se. The Se-induced increase in the content of hydrophobic amino acids and β-sheets synergistically increases the thermal stability of the protein. Moderate Se application altered the functional properties of mung bean protein, which was mainly reflected in the significant increase in oil holding capacity (OHC) and foaming capacity (FC). In addition, the increase in SH and β-sheets induced by exogenous Se could alter the protein intermolecular network, contributing to the increase in storage modulus (G\') and loss modulus (G″), which resulted in the formation of more highly elastic gels. This study further promotes the application of mung bean protein in the field of food processing and provides a theoretical basis for the extensive development of Se-enriched mung bean protein.

    杰克豆的可提取性和消化性差限制了它们在食品系统中的应用。热处理可以是破坏植物基质的致密构象并使固有的抗营养素失活的处理工具。因此,这项研究调查了传统的热辅助(HA-)和微波辅助(MA-)萃取处理对结构的影响,功能属性,在不同的提取pH下,杰克豆蛋白浓缩物(JBPC)的消化率。本研究带来的新颖性是建立热处理/提取pH组合,以提高JBPC的技术功能和消化率。加热(50°C持续1小时)和连续微波功率(400W,600W,和800W持续5分钟)在三个提取pH值(9.0、10.0和11.0)下进行了研究。随着提取pH值的增加,蛋白质含量显著下降,并观察到β-片结构,在pH11.0>10.0>9.0的顺序。使用HA处理提取的JBPC显示出最高的表面疏水性(90.02)和巯基含量。在功能属性中,在400W下,MA提取的JBPC显示出显着改善的溶解度(93.45%),乳化活性指数(45.23m2/g),与其他热处理相比,发泡能力(141.70%)。水解度结果表明,在400W的低功率水平下,MA处理提高了JBPC的体外消化率。这些发现表明,无论提取pH如何,MA提取处理都可以改善JBPC的功能和营养特性。因此,扩大在食品系统中的潜在应用。
    The poor extractability and digestibility of jack beans restrict their application in food systems. Thermal treatment could be a processing tool to disrupt the compact conformation of the plant matrix and inactivate inherent antinutrients. Therefore, this research investigated the impact of conventional heat-aided (HA-) and microwave-aided (MA-) extraction treatments on the structure, functional properties, and digestibility of jack bean protein concentrate (JBPC) under varying extraction pH. The novelty brought by the present study is establishing the thermal treatment/extraction pH combinations for improving techno-functionalities and digestibility of JBPC. Heat (50 °C for 1 h) and sequential microwave power (400 W, 600 W, and 800 W for 5 min) at three extraction pH (9.0, 10.0, and 11.0) were studied. Upon increasing extraction pH, a significant decrease in the protein content, and β-Sheet structure was observed, in the order of pH 11.0 > 10.0 > 9.0. JBPC extracted using HA treatments displayed the highest contents of surface hydrophobicity (90.02) and sulfhydryl groups. In functional properties, MA-extracted JBPC under 400 W showed significantly improved solubility (93.45 %), emulsifying activity index (45.23 m2/g), and foaming capacity (141.70 %) when compared to other thermal treatments. The degree of hydrolysis result revealed that MA treatment improved the JBPC in vitro digestibility at a low power level of 400 W. These findings suggest that MA extraction treatment can improve the functional and nutritional properties of JBPC regardless of the extraction pH, and thus, expand the potential application in food systems.
