    OBJECTIVE: The objective of this work was to determine the diagnostic accuracy of panoramic radiography in detecting degenerative diseases of the temporomandibular joint.
    METHODS: The protocol was registered at the PROSPERO website. To consider the eligibility of studies to be included/excluded from this review, the acronym \"PIRDS\" was used and appropriate word combinations and truncations were adapted in the following electronic databases: PubMed/Medline, EMBASE, Latin American and Caribbean Literature on Health Sciences, Web of Science, Scopus, and Cochrane Library.
    RESULTS: A total of 2572 references, after the removal of duplicates, were retrieved from the eight electronic databases. After reading the titles and abstracts, a total of 26 articles were selected for full reading, of which ten were excluded, resulting in 16 articles included for qualitative synthesis. All in vivo studies were classified as having a low risk of bias. Regarding in vitro studies none of the included studies scored below 80% in the overall evaluation.
    CONCLUSIONS: Both in vitro and in vivo studies consistently report a low accuracy in detecting degenerative diseases of the temporomandibular joint using panoramic radiography.
    CONCLUSIONS: Cone-beam computed tomography offers a superior image quality without overlapping structures and a higher accuracy compared to panoramic radiography. However, panoramic radiography can still serve as an initial examination when combined with a clinical assessment. CBCT should be reserved for cases where there are evident clinical and/or radiographic alterations that recommend its use. This approach ensures a judicious and cost-effective use of CBCT resources.

    老年退行性疾病患者数量的增加带来了额外的医疗和经济压力,这增加了社会的负担。运动康复机器人(SRR)的发展在其应用的技术水平上变得越来越复杂;但是,很少有研究分析了它是如何工作的,以及它在帮助康复方面的有效性,针对老年患者的个性化运动康复计划较少。这项研究的目的是分析不同类型的SRR的工作方法和效果,然后提出应用SRR增强老年退行性疾病患者身体能力的可行性。研究人员的团队搜索了633篇英语期刊文章,在过去的五年里,他们选择了其中的38个进行叙事文献综述。我们的总结发现以下几点:(1)当前的SRR类型通常被归类为末端执行器机器人,聪明的步行者,智能机器人助推器,和外骨骼机器人-外骨骼机器人被发现是最广泛使用的。(2)当前的工作方法包括以辅助工具为主要中介-即,机器人帮助患者参与;患者作为主要中介-即,患者主导辅助工具参与;传感器作为中介,即肌电驱动机器人促进患者参与。(3)使用SRR时,老年患者的恢复效果优于传统的单运动恢复方法。尤其是在力量上,balance,耐力,和协调。然而,使用SRR后,其速度或敏捷性没有显着提高。
    The increase in the number of elderly patients with degenerative diseases has brought additional medical and financial pressures, which are adding to the burden on society. The development of sports rehabilitation robotics (SRR) is becoming increasingly sophisticated at the technical level of its application; however, few studies have analyzed how it works and how effective it is in aiding rehabilitation, and fewer individualized exercise rehabilitation programs have been developed for elderly patients. The purpose of this study was to analyze the working methods and the effects of different types of SRR and then to suggest the feasibility of applying SRR to enhance the physical abilities of elderly patients with degenerative diseases. The researcher\'s team searched 633 English-language journal articles, which had been published over the past five years, and they selected 38 of them for a narrative literature review. Our summary found the following: (1) The current types of SRR are generally classified as end-effector robots, smart walkers, intelligent robotic rollators, and exoskeleton robots-exoskeleton robots were found to be the most widely used. (2) The current working methods include assistant tools as the main intermediaries-i.e., robots assist patients to participate; patients as the main intermediaries-i.e., patients dominate the assistant tools to participate; and sensors as the intermediaries-i.e., myoelectric-driven robots promote patient participation. (3) Better recovery was perceived for elderly patients when using SRR than is generally achieved through the traditional single-movement recovery methods, especially in strength, balance, endurance, and coordination. However, there was no significant improvement in their speed or agility after using SRR.

    类胡萝卜素是天然的脂溶性色素,在植物中产生黄色到红色,并在蔬菜和水果中提供明亮的颜色。叶黄素属于类胡萝卜素家族的叶黄素亚组,在自然界的光合作用和光保护中起着至关重要的作用。在人体中,叶黄素,连同其异构体玉米黄质及其代谢产物内消旋玉米黄质,积聚在视网膜的黄斑中,负责中央,高分辨率,和颜色视觉。作为一种生物活性植物化学物质,叶黄素具有重要的生理功能,提供光保护,防止损坏的蓝光,以及氧化剂的中和和和细胞膜的结构和功能完整性的保存。作为一种有效的抗氧化剂和抗炎剂,不幸的是,叶黄素由于其亲脂性而具有低生物利用度,并且由于其共轭双键而具有低稳定性。为了增强叶黄素的稳定性和生物利用度,并实现其对目标的控制递送,纳米级输送系统,它们具有释放生物活性化合物的巨大潜力,开始被雇用。当前的审查强调了与将叶黄素纳入有前途的纳米级递送系统相关的优势和创新,如脂质体,纳米乳液,聚合物纳米颗粒,和聚合物-脂质混合纳米颗粒,以及它们独特的理化性质。
    Carotenoids are natural lipid-soluble pigments that produce yellow to red colors in plants as well as providing bright coloration in vegetables and fruits. Lutein belongs to the xanthophyll subgroup of the carotenoid family, which plays an essential role in photosynthesis and photoprotection in nature. In the human body, lutein, together with its isomer zeaxanthin and its metabolite meso-zeaxanthin, accumulates in the macula of the eye retina, which is responsible for central, high-resolution, and color vision. As a bioactive phytochemical, lutein has essential physiological functions, providing photoprotection against damaging blue light, along with the neutralization of oxidants and the preservation of the structural and functional integrity of cellular membranes. As a potent antioxidant and anti-inflammatory agent, lutein unfortunately has a low bioavailability because of its lipophilicity and a low stability as a result of its conjugated double bonds. In order to enhance lutein stability and bioavailability and achieve its controlled delivery to a target, nanoscale delivery systems, which have great potential for the delivery of bioactive compounds, are starting to be employed. The current review highlights the advantages and innovations associated with incorporating lutein within promising nanoscale delivery systems, such as liposomes, nanoemulsions, polymer nanoparticles, and polymer-lipid hybrid nanoparticles, as well as their unique physiochemical properties.

    番茄作为新鲜蔬菜在世界范围内被食用,因为它们含有高含量的必需营养素和富含抗氧化剂的植物化学物质。西红柿含有矿物质,维生素,蛋白质,必需氨基酸(亮氨酸,苏氨酸,缬氨酸,组氨酸,赖氨酸,精氨酸),单不饱和脂肪酸(亚油酸和亚麻酸),类胡萝卜素(番茄红素和β-类胡萝卜素)和植物甾醇(β-谷甾醇,菜油甾醇和豆甾醇)。番茄红素是番茄和基于番茄的食品中的主要膳食类胡萝卜素,据报道人类食用番茄红素可以预防癌症,心血管疾病,认知功能和骨质疏松症。在番茄中存在的酚类化合物中,槲皮素,山奈酚,柚皮苷,咖啡酸和叶黄素是最常见的。这些化合物中的许多具有抗氧化活性,并且在保护人体免受各种氧化应激相关疾病方面是有效的。饮食西红柿增加身体的抗氧化剂水平,捕获活性氧并减少对膜脂等重要生物分子的氧化损伤,酶蛋白和DNA,从而改善氧化应激。我们回顾了番茄的营养和植物化学成分。此外,这些成分对人体健康的影响,特别是在改善一些退行性疾病方面,也讨论了。
    Tomatoes are consumed worldwide as fresh vegetables because of their high contents of essential nutrients and antioxidant-rich phytochemicals. Tomatoes contain minerals, vitamins, proteins, essential amino acids (leucine, threonine, valine, histidine, lysine, arginine), monounsaturated fatty acids (linoleic and linolenic acids), carotenoids (lycopene and β-carotenoids) and phytosterols (β-sitosterol, campesterol and stigmasterol). Lycopene is the main dietary carotenoid in tomato and tomato-based food products and lycopene consumption by humans has been reported to protect against cancer, cardiovascular diseases, cognitive function and osteoporosis. Among the phenolic compounds present in tomato, quercetin, kaempferol, naringenin, caffeic acid and lutein are the most common. Many of these compounds have antioxidant activities and are effective in protecting the human body against various oxidative stress-related diseases. Dietary tomatoes increase the body\'s level of antioxidants, trapping reactive oxygen species and reducing oxidative damage to important biomolecules such as membrane lipids, enzymatic proteins and DNA, thereby ameliorating oxidative stress. We reviewed the nutritional and phytochemical compositions of tomatoes. In addition, the impacts of the constituents on human health, particularly in ameliorating some degenerative diseases, are also discussed.

    Aging is an inevitable process characterized by the accumulation of degenerative damage, leading to serious diseases that affect human health. Studies on aging aim to develop pre-protection or therapies to delay aging and age-related diseases. A preventive approach is preferable to clinical treatment not only to reduce investment but also to alleviate pain in patients. Adjusting daily diet habits to improve the aging condition is a potentially attractive strategy. Fruits and vegetables containing active compounds that can effectively delay the aging process and reduce or inhibit age-related degenerative diseases have been identified. The signaling pathways related to aging in Caenorhabditis elegans are evolutionarily conserved; thus, studying antiaging components by intervening senescence process may contribute to the prevention and treatment of age-related diseases in humans. This review focuses on the effects of food-derived extracts or purified substance on antiaging in nematodes, as well as the underlying mechanisms, on the basis of several major signaling pathways and key regulatory factors in aging. The aim is to provide references for a healthy diet guidance and the development of antiaging nutritional supplements. Finally, challenges in the use of C. elegans as the antiaging evaluation model are discussed, together with the development that potentially inspire novel strategies and research tools.

    The transformation of polypeptide chains from their globular native structure to fibrillar aggregates has been a matter of great concern because of the involvement of these aggregates in the onset of several degenerative diseases. These aggregates exhibit highly ordered cross β sheet structures and are known as \'amyloids\'. Formation of amyloids in the body is associated with cytotoxicity due to direct interaction of the aggregated species with the cell membrane leading to cellular permeability or due to loss of functionality of the proteins involved in the amyloid formation. The preference of polypeptide chains to remain in their native conformation or to aggregate into amyloids is guided by several factors such as its conformation at specific condition, concentration, physicochemical properties of the amino acid sequence and so on. In the current review, we have reviewed the different factors that guide the transition of proteins from their natively folded state to the amyloidogenic state. Understanding the critical determinants of amyloidogenesis is vital towards deciphering the molecular mechanism of amyloidogenesis and for the development of effective therapeutics against amyloidosis.
