    中枢神经系统的发育非常复杂,涉及许多必须以高时空精度进行的发育过程。这需要一系列复杂且协调良好的分子过程,例如,各种蛋白质和脂类。在这些过程中放松管制,包括基因突变,会导致最严重的不良发展。本综述提供了蛋白家族可塑性相关基因(PRG1-5)的概述,包括它们在神经元分化过程中的作用,它们的分子相互作用,以及他们参与各种疾病。由于这些蛋白质可以调节生物活性脂质的功能,它们能够影响各种细胞过程。此外,它们在开发过程中受到动态调节,因此在突触的发育和功能中起着重要作用。第一次研究,不仅在小鼠实验中进行,而且在人类中进行,揭示了这些蛋白质的突变或失调会导致脂质代谢的变化,导致严重的神经功能缺损.近年来,随着越来越多的研究表明它们参与了广泛的疾病,PRG之间已知和未知相互作用的复杂性和广谱,脂质,和蛋白质使它们成为有希望和有趣的潜在新型治疗靶点。
    The development of the central nervous system is highly complex, involving numerous developmental processes that must take place with high spatial and temporal precision. This requires a series of complex and well-coordinated molecular processes that are tighly controlled and regulated by, for example, a variety of proteins and lipids. Deregulations in these processes, including genetic mutations, can lead to the most severe maldevelopments. The present review provides an overview of the protein family Plasticity-related genes (PRG1-5), including their role during neuronal differentiation, their molecular interactions, and their participation in various diseases. As these proteins can modulate the function of bioactive lipids, they are able to influence various cellular processes. Furthermore, they are dynamically regulated during development, thus playing an important role in the development and function of synapses. First studies, conducted not only in mouse experiments but also in humans, revealed that mutations or dysregulations of these proteins lead to changes in lipid metabolism, resulting in severe neurological deficits. In recent years, as more and more studies have shown their involvement in a broad range of diseases, the complexity and broad spectrum of known and as yet unknown interactions between PRGs, lipids, and proteins make them a promising and interesting group of potential novel therapeutic targets.

    Malate dehydrogenase (MDH) is pivotal in mammalian tissue metabolism, participating in various pathways beyond its classical roles and highlighting its adaptability to cellular demands. This enzyme is involved in maintaining redox balance, lipid synthesis, and glutamine metabolism and supports rapidly proliferating cells\' energetic and biosynthetic needs. The involvement of MDH in glutamine metabolism underlines its significance in cell physiology. In contrast, its contribution to lipid metabolism highlights its role in essential biosynthetic processes necessary for cell maintenance and proliferation. The enzyme\'s regulatory mechanisms, such as post-translational modifications, underscore its complexity and importance in metabolic regulation, positioning MDH as a potential target in metabolic dysregulation. Furthermore, the association of MDH with various pathologies, including cancer and neurological disorders, suggests its involvement in disease progression. The overexpression of MDH isoforms MDH1 and MDH2 in cancers like breast, prostate, and pancreatic ductal adenocarcinoma, alongside structural modifications, implies their critical role in the metabolic adaptation of tumor cells. Additionally, mutations in MDH2 linked to pheochromocytomas, paragangliomas, and other metabolic diseases emphasize MDH\'s role in metabolic homeostasis. This review spotlights MDH\'s potential as a biomarker and therapeutic target, advocating for further research into its multifunctional roles and regulatory mechanisms in health and disease.

    UNASSIGNED: Due to the high-density farming of Larimichthys crocea over the years, diseases caused by pathogens such as bacteria, viruses, and parasites frequently occur in Ningbo, posing a huge threat and challenge to the sustainable and healthy development of the L. crocea\'s bay farming industry. In order to understand the diseases occurrence in L. crocea farming in Ningbo area, an epidemiological investigation of L. crocea diseases was carried out through regular sampling in 2023.
    UNASSIGNED: From April to October 2023, routine sampling of L. crocea was conducted monthly in various farming areas in Ningbo. Each time, live or dying L. crocea with obvious clinical symptoms were sampled, with a total number of 55 L. crocea collected. The samples were preserved in ice bags and transported to the laboratory for pathogen detection(including bacterial isolation and identification,virus identification, and parasites detection).
    UNASSIGNED: A total of fifty-five fish dying L. crocea with obvious clinical symptoms were collected in this study, of which 78.18% (43/55) were detected with symptoms caused by pathogenic infection, while 21.82% (12/55) did not have identified pathogens, which were presumed to be breeding abrasions, nutritional metabolic disorders, unconventional pathogens infection or other reasons. A total of twenty-five pathogenic bacteria strains were isolated, which mainly were Pseudomonas plecoglossicida and Vibrio harveyi, accounting for 52% (13/25) and 32% (8/25) of the pathogenic bacteria strains, respectively. Among them, both V. harveyi and Streptococcus. iniae co-infected one fish. Additionally, three other bacterial strains including Nocardia seriolae, Staphylococcus Saprophyticus, and Photobacterium damselae subsp.damselae were isolated. Microscopic examination mainly observed two parasites, Cryptocaryon irritans and Neobenedenia girellae. In virus detection, the red sea bream iridovirus (RSIV) was mainly detected in L. crocea. Statistical analysis showed that among the fish with detected pathogens, 55.81% (24/43) had bacterial infections, 37.21% (16/43) had parasitic infections, and 37.21% (16/43) had RSIV infections. Among them, five fish had mixed infections of bacteria and parasites, three had mixed infections of bacteria and viruses, three had mixed infections of parasites and viruses, and one L. crocea had mixed infections of viruses, bacteria, and parasites.
    UNASSIGNED: These findings indicate that these three major types of diseases are very common in the L. crocea farming area in Ningbo, implying the complexity of mixed infections of multiple diseases.

    成纤维细胞生长因子(FGFs)是一个多功能的肽生长因子家族,涉及各种生物学功能。包括细胞生长和分化,胚胎发育,血管生成,和新陈代谢。FGF/FGF受体(FGFR)信号异常与多种疾病如癌症的发病机制有关。代谢性疾病,和炎症性疾病。值得注意的是,巨噬细胞极化,涉及不同的功能表型,在组织修复中起着至关重要的作用,稳态维持,和免疫反应。最近的研究表明,FGF/FGFR信号通路与巨噬细胞的极化密切相关,表明它们可能是与功能失调的巨噬细胞相关疾病的治疗操作的潜在靶标。在这篇文章中,我们提供了结构的概述,函数,和FGFs的下游调控途径,以及FGF信号和巨噬细胞极化之间的串扰。此外,我们总结了利用FGF信号调节巨噬细胞极化的潜在应用。
    Fibroblast growth factors (FGFs) are a versatile family of peptide growth factors that are involved in various biological functions, including cell growth and differentiation, embryonic development, angiogenesis, and metabolism. Abnormal FGF/FGF receptor (FGFR) signaling has been implicated in the pathogenesis of multiple diseases such as cancer, metabolic diseases, and inflammatory diseases. It is worth noting that macrophage polarization, which involves distinct functional phenotypes, plays a crucial role in tissue repair, homeostasis maintenance, and immune responses. Recent evidence suggests that FGF/FGFR signaling closely participates in the polarization of macrophages, indicating that they could be potential targets for therapeutic manipulation of diseases associated with dysfunctional macrophages. In this article, we provide an overview of the structure, function, and downstream regulatory pathways of FGFs, as well as crosstalk between FGF signaling and macrophage polarization. Additionally, we summarize the potential application of harnessing FGF signaling to modulate macrophage polarization.

    蛋白质赖氨酸巴豆化(Kcr)是蛋白质翻译后修饰的一种保守形式,在一系列细胞生理和病理过程中起着重要作用。赖氨酸ε-氨基是这种修饰的主要位点,导致四碳平面赖氨酸巴豆化,其在结构上和功能上与这些残基的乙酰化不同。已经在组蛋白和非组蛋白蛋白上鉴定出高水平的Kcr修饰。本综述提供了有关生物医学环境中蛋白质Kcr修饰的研究进展的最新信息,并讨论了Kcr修饰控制一系列生物学过程的机制。此外,鉴于蛋白质Kcr修饰在疾病发作和进展中的重要性,阐明了Kcr调节因子作为治疗靶标的潜在可行性。
    Protein lysine crotonylation (Kcr) is one conserved form of posttranslational modifications of proteins, which plays an important role in a series of cellular physiological and pathological processes. Lysine ε-amino groups are the primary sites of such modification, resulting in four-carbon planar lysine crotonylation that is structurally and functionally distinct from the acetylation of these residues. High levels of Kcr modifications have been identified on both histone and non-histone proteins. The present review offers an update on the research progression regarding protein Kcr modifications in biomedical contexts and provides a discussion of the mechanisms whereby Kcr modification governs a range of biological processes. In addition, given the importance of protein Kcr modification in disease onset and progression, the potential viability of Kcr regulators as therapeutic targets is elucidated.

    使用荷兰糖尿病协会杂志(NederlandseVerenigingvanSuikerzieken),本文介绍了1945年至1970年间荷兰早期患者组织在慢性疾病糖尿病及其管理方面的作用。在1940年代和1950年代,通过平衡概念调和了纪律(由卫生专业人员指导)和独立性(由糖尿病患者指导)的双重目标。有组织的糖尿病患者发挥了特别大的作用,结果,独立性得到了特别强调。这使得有组织的患者可以在与劳动有关的社会健康方面重新配置他们的疾病和身份,战后重建时期的家庭和社会。在1960年代后期,这种社会概念转变为个人的健康概念,其中平衡概念失去了突出地位,尽管在1960年代初期进行了短暂的医疗干预。
    Using the journal of the Dutch Diabetics Association (Nederlandse Vereniging van Suikerzieken), the article provides insight into the role of an early patient organisation in conceptualising the chronic disease diabetes and its management in the Netherlands between 1945 and 1970. The dual aims of discipline (steered by health professionals) and independence (steered by diabetics) were reconciled through the concept of balance during the 1940s and 1950s. Organised diabetics played a particularly large role, and independence got particular emphasis as a consequence. This made it possible for organised patients to reconfigure their disease and identity in terms of social health in relation to labour, family and society in the post-war reconstruction period. In the late 1960s, this social concept transformed into a personal concept of health in which the concept of balance lost its prominence, despite a short intermezzo of medicalisation in the early 1960s.

    Community-based participatory research (CBPR) using barbershop interventions is an emerging approach to address health disparities and promote health equity. Barbershops serve as trusted community settings for health education, screening services, and referrals. This narrative mini-review provides an overview of the current state of knowledge regarding CBPR employing barbershop interventions and explores the potential for big data involvement to enhance the impact and reach of this approach in combating chronic disease. CBPR using barbershop interventions has shown promising results in reducing blood pressure among Black men and improving diabetes awareness and self-management. By increasing testing rates and promoting preventive behaviors, barbershop interventions have been successful in addressing infectious diseases, including HIV and COVID-19. Barbershops have also played roles in promoting cancer screening and increasing awareness of cancer risks, namely prostate cancer and colorectal cancer. Further, leveraging the trusted relationships between barbers and their clients, mental health promotion and prevention efforts have been successful in barbershops. The potential for big data involvement in barbershop interventions for chronic disease management offers new opportunities for targeted programs, real-time monitoring, and personalized approaches. However, ethical considerations regarding privacy, confidentiality, and data ownership need to be carefully addressed. To maximize the impact of barbershop interventions, challenges such as training and resource provision for barbers, cultural appropriateness of interventions, sustainability, and scalability must be addressed. Further research is needed to evaluate long-term impact, cost-effectiveness, and best practices for implementation. Overall, barbershops have the potential to serve as key partners in addressing chronic health disparities and promoting health equity.

    已知植物酚类具有多种生物活性。本研究旨在提取和检查宝芒果(MangiferaindicaL.var。)果皮乙醇提取物(MPE)。Further,抗氧化剂,抗糖尿病药(α-淀粉酶,和α-葡萄糖苷酶抑制活性),和抗阿尔茨海默病(AD)(乙酰胆碱酯酶(AChE),丁酰胆碱酯酶(BChE),测定MPE的β-分泌酶(BACE-1)抑制活性)功效。结果表明,芒果苷(8755.89mg/100g提取物)是MPE中的主要酚类化合物。抗氧化机制表明,与还原力(FRAP)或氧自由基吸收能力(ORAC)相比,MPE具有更高的自由基清除能力(4266.70µmolTE/g提取物)。对糖尿病和AD相关酶的进一步体外酶抑制试验表明,与标准药物(阿卡波糖)相比,MPE对糖尿病相关酶具有更强的抑制作用(P<0.05)。而与它们的标准药物(多奈哌齐)相比,观察到对AD相关酶的IC50值较低(P<0.05)。结果表明,泰宝芒果果皮副产品可以成为降低糖尿病和改善认知健康的潜在营养保健品来源。
    Plant phenolics have been known for various biological activities. This study aims to extract and examine the presence of phenolics in Bao mango (Mangifera indica L. var.) peel ethanolic extract (MPE). Further, antioxidant, anti-diabetic (α-amylase, and α-glucosidase inhibitory activity), and anti- Alzheimer\'s disease (AD) (acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and β-secretase (BACE-1) inhibitory activity) efficacy of MPE were determined. The results indicated that mangiferin (8755.89 mg/ 100 g extract) was the major phenolic compound in MPE. An antioxidant mechanism revealed that MPE had a higher radical scavenging ability (4266.70 µmol TE/g extract) compared to reducing power (FRAP) or oxygen radical absorption capacity (ORAC). Further in-vitro enzyme inhibitory assay against diabetic and AD involved enzymes showed that MPE had stronger inhibitory action against an enzyme involved in diabetes compared to their standard drug (Acarbose) (P < 0.05). While a lower IC50 value was observed against AD-involved enzymes compared to their standard drug (donepezil) (P < 0.05). The results show that Thai Bao mango peel byproduct can be a potential source of nutraceuticals to lower diabetes and improve cognitive health.
