Objectives: This study aimed to assess the individual and combined effects of SAE and Met on the expression of genes related to insulin signaling, oxidative stress, hormonal imbalance, insulin resistance, and dyslipidemia in rats with induced PCOS.
Methods: The estrous cycle of 50 adult Wistar female rats was monitored through vaginal smears. Subsequently, the rats were randomly assigned into five groups of 10, including control (receiving 1ml of carboxymethyl cellulose for 49 days), induction (letrozole at 1mg/kg/d for 21 days), SAE, Met, and SAE/Met. SAE and Met were orally administered at doses of 400mg/kg/d and 250mg/kg/d on day 22 and continued for an additional 28 days. Vaginal smears were analyzed, and gene expression levels of GLUT4, SIRT1, TNF-α, and INSR were evaluated using RT-qPCR. Antioxidant parameters were assessed using detection kits.
Results: Treatment with SAE and Met restored a regular estrous cycle pattern in PCOS rats. Furthermore, SAE and Met treatment improved hormonal balance, dyslipidemia, and hyperglycemia in the rats. Administration of SAE and Met significantly elevated levels of antioxidant enzymes SOD and GPx in ovarian tissue (P<0.001). Additionally, mRNA levels of GLUT4, SIRT1, and INSR were significantly increased in ovarian tissue following SAE and Met treatment, while TNF-α gene expression decreased significantly (P<0.0001).
Conclusion: The findings suggest that SAE and Met aqueous extract exert protective effects on letrozole-induced PCOS in rats by modulating gene expression associated with insulin signaling and oxidative stress.
研究目的本研究旨在评估SAE和Met对诱导多囊卵巢综合征大鼠胰岛素信号转导、氧化应激、内分泌失调、胰岛素抵抗和血脂异常相关基因表达的单独和联合影响:方法:通过阴道涂片监测50只成年Wistar雌性大鼠的发情周期。随后,大鼠被随机分为5组,每组10只,包括对照组(接受1毫升羧甲基纤维素,共49天)、诱导组(来曲唑,1毫克/千克/天,共21天)、SAE组、Met组和SAE/Met组。第22天开始口服SAE和Met,剂量分别为400毫克/千克/天和250毫克/千克/天,并持续28天。对阴道涂片进行分析,并使用 RT-qPCR 评估 GLUT4、SIRT1、TNF-α 和 INSR 的基因表达水平。使用检测试剂盒评估了抗氧化参数:结果:用SAE和Met治疗后,多囊卵巢综合征大鼠恢复了正常的发情周期模式。此外,SAE 和 Met 治疗还改善了大鼠的激素平衡、血脂异常和高血糖。服用 SAE 和 Met 能明显提高卵巢组织中抗氧化酶 SOD 和 GPx 的水平(PC 结论:研究结果表明,SAE 和 Met 能提高卵巢组织中抗氧化酶 SOD 和 GPx 的水平:研究结果表明,SAE和Met水提取物通过调节与胰岛素信号传导和氧化应激相关的基因表达,对来曲唑诱导的多囊卵巢综合征大鼠具有保护作用。

Introduction: During the COVID-19 pandemic, single use medical devices' supply (SUMD) was marked by repetitive and unforeseen interruptions. The present study aimed to determine the risks related to the processes of management of medical devices in our CHU according to a method of failure mode, effect and criticality analysis (FMECA).
Methods: Qualified healthcare professionals were recruited to form a multidisciplinary consensus committee. By analyzing the process map, all failure modes, causes and consequences were identified through brainstorming meetings. They were then classified taking into account the criticality index (CI) calculated according to three parameters: frequency, severity, and detectability. The prioritization was carried out by considering the mean and the median values of the CI as limits. Corrective and preventive actions were then proposed.
Results: A total of 49 failure modes were identified, accumulating 4466 criticality points. The most critical step is that relating to the inter-depot order with a CI equal to 783 points. An action plan was developed, allows us to control 64% of the overall criticality of the risks linked to the process. Three main lines of action have been proposed: continuous training, especially for managerial and administrative tasks, logistical improvement (architectural reorganization and implementation of systems for securing the circuit of SUMDs) and support for the digitization of hospital pharmacy.
Conclusion: The FMECA is a consensual method, which makes it possible to propose actions in order to reduce the risks linked to the process of managing medical devices. Optimizing the estimation of needs, strengthening communication with stakeholders and securing the circuit are essential to guarantee the availability of SUMDs for the benefit of the patient.

The study is designed to advocate for a harmonized medical device regulatory framework throughout the BRICS countries with a view to facilitating trade, attracting investments and safeguarding patients' health. The development of the medical devices industry in BRICS countries is impeded by a lack of standardized regulation. A harmonized framework would facilitate the approval process, promotion of innovation and wider access for patients to modern medical technologies. The paper analyses existing regulatory frameworks for medical devices in BRICS countries and identifies their strengths and weaknesses. Specific measures to harmonize such as standardization of technology, interoperability and the implementation of transparent licensing procedures are also proposed. The study indicates that a joint committee should be set up to supervise legal harmonization, standardization of classification and development of specific technical specifications. It also provides information about the regulatory framework in different countries, such as Brazil, Russia, India, China and South Africa, on classification of medical devices. Report emphasizes the need for a harmonized regulatory framework to rapidly introduce new healthcare technologies. It suggests that the BRICS countries can create a more conducive environment for the medical device industry, ultimately benefiting patients, manufacturers and the overall healthcare system by aligning their legislation.

The coagulation and immune system, both essential physiological systems in the human body, are intricately interconnected and play a critical role in determining the overall health of patients. These systems collaborate via various shared regulatory pathways, such as the Tissue Factor (TF) Pathway. Immunological cells that express TF and generate pro-inflammatory cytokines have the ability to affect coagulation. Conversely, coagulation factors and processes have a reciprocal effect on immunological responses by stimulating immune cells and regulating their functions. These interconnected pathways play a role in both preserving well-being and contributing to a range of pathological disorders. The close relationship between blood clotting and inflammation in the development of vascular disease has become a central focus of clinical study. This research specifically examines the crucial elements of this interaction within the contexts of cardiovascular disease and acute coronary syndrome. Tissue factor, the primary trigger of the extrinsic coagulation pathway, has a crucial function by inducing a proinflammatory reaction through the activation of coagulation factors. This, in turn, initiates coagulation and subsequent cellular signalling pathways. Protease-activated receptors establish the molecular connection between coagulation and inflammation by interacting with activated clotting factors II, X, and VII. Thrombosis, a condition characterised by the formation of blood clots, is the most dreaded consequence of cardiovascular disorders and a leading cause of death globally. Consequently, it poses a significant challenge to healthcare systems. Antithrombotic treatments efficiently target platelets and the coagulation cascade, but they come with the inherent danger of causing bleeding. Furthermore, antithrombotics are unable to fully eliminate thrombotic events, highlighting a treatment deficiency caused by a third mechanism that has not yet been sufficiently addressed, namely inflammation. Understanding these connections may aid in the development of novel approaches to mitigate the harmful mutual exacerbation of inflammation and coagulation. Gaining a comprehensive understanding of the intricate interaction among these systems is crucial for the management of diseases and the creation of efficacious remedies. Through the examination of these prevalent regulatory systems, we can discover novel therapeutic approaches that specifically target these complex illnesses. This paper provides a thorough examination of the reciprocal relationship between the coagulation and immune systems, emphasising its importance in maintaining health and understanding disease processes. This review examines the interplay between inflammation and thrombosis and its role in the development of thrombotic disorders.
凝血系统和免疫系统都是人体重要的生理系统,它们之间有着错综复杂的联系,在决定患者整体健康方面发挥着至关重要的作用。这些系统通过组织因子(TF)途径等各种共享调控途径相互协作。表达 TF 并产生促炎细胞因子的免疫细胞能够影响凝血功能。相反,凝血因子和凝血过程通过刺激免疫细胞并调节其功能,对免疫反应产生相互影响。这些相互关联的途径既能维护人体健康,也能导致一系列病理紊乱。凝血和炎症在血管疾病发展过程中的密切关系已成为临床研究的核心重点。这项研究特别探讨了心血管疾病和急性冠状动脉综合征中这种相互作用的关键因素。组织因子是外凝血途径的主要触发因子,其关键作用是通过激活凝血因子诱发促炎反应。这反过来又启动了凝血和随后的细胞信号通路。蛋白酶活化受体通过与活化的凝血因子 II、X 和 VII 相互作用,建立了凝血与炎症之间的分子联系。血栓形成是心血管疾病最可怕的后果,也是全球死亡的主要原因。因此,它给医疗保健系统带来了巨大挑战。抗血栓治疗能有效地针对血小板和凝血级联反应,但也有引起出血的固有危险。此外,抗血栓药物无法完全消除血栓事件,这凸显了尚未充分解决的第三个机制(即炎症)造成的治疗缺陷。了解这些联系有助于开发新的方法,减轻炎症和凝血相互加重的危害。全面了解这些系统之间错综复杂的相互作用对于疾病的治疗和创造有效的疗法至关重要。通过研究这些普遍存在的调节系统,我们可以发现专门针对这些复杂疾病的新型治疗方法。本文深入探讨了凝血系统和免疫系统之间的相互关系,强调了它们在维持健康和了解疾病过程中的重要性。这篇综述探讨了炎症与血栓形成之间的相互作用及其在血栓性疾病发展中的作用。

Cyclodextrins are enabling pharmaceutical excipients that solubilize and stabilize drugs in aqueous formulations. Cyclodextrins possess very favorable pharmacokinetic and toxicological profiles and are commonly used in marketed drug products for oral and parenteral administration. However, their use in ophthalmic products is still very limited. Cyclodextrins have a broad range of physical properties that are specifically appropriate for designing topical ophthalmic dosage forms. Additionally, both the regulatory and intellectual property environments have been cleared over the last years and should foster their use for designing new drugs for ophthalmic use.

Parkinson's disease (PD) is a widely seen neurodegenerative condition recognized by misfolded α-synuclein (αSyn) protein, a prominent indicator for PD and other synucleinopathies. Motor symptoms like stiffness, akinesia, rest tremor, and postural instability coexist with nonmotor symptoms that differ from person to person in the development of PD. These symptoms arise from a progressive loss of synapses and neurons, leading to a widespread degenerative process in multiple organs. Implementing medical and surgical interventions, such as deep brain stimulation, has enhanced individuals' overall well-being and long-term survival with PD. It should be mentioned that these treatments cannot stop the condition from getting worse. The complicated structure of the brain and the existence of a semi-permeable barrier, commonly known as the BBB, have traditionally made medication delivery for the treatment of PD a challenging endeavor. The drug's low lipophilic nature, enormous size, and peculiarity for various ATP-dependent transport mechanisms hinder its ability to enter brain cells. This article delves at the potential of drug delivery systems based on chitosan (CS) to treat PD.
帕金森病(PD)是一种广泛存在的神经退行性疾病,其特征是α-突触核蛋白(αSyn)蛋白折叠错误,这是帕金森病和其他突触核蛋白病的主要指标。在脊髓灰质炎的发病过程中,僵硬、运动障碍、静止性震颤和姿势不稳等运动症状与非运动症状并存,这些症状因人而异。这些症状源于突触和神经元的逐渐丧失,导致多个器官出现广泛的退行性病变。脑深部刺激等医疗和外科干预措施提高了帕金森病患者的整体健康水平和长期存活率。值得一提的是,这些治疗方法并不能阻止病情恶化。大脑结构复杂,存在半透膜屏障(俗称 "BBB"),这使得治疗帕金森氏症的药物输送一直是一项具有挑战性的工作。药物的低亲脂性、巨大的体积以及各种依赖 ATP 的转运机制的特殊性阻碍了其进入脑细胞的能力。本文深入探讨了基于壳聚糖(CS)的给药系统治疗帕金森病的潜力。
