Phenylacetylglycine (PAGly) is a small molecule derived from phenylalanine in the gut via glycine degradation and conjugation. It has been associated with both the progression of atherosclerosis and protective effects on the myocardium. This study evaluated the function and the underlying mechanisms of PAGly in a rat cerebral ischemia/reperfusion (I/R) injury model. The results indicated that PAGly markedly alleviated cerebral infarct volume (P = 0.0024) and improved the neurobehavioral outcomes (P = 0.0149) after I/R injury. PAGly is structurally analogous to catecholamines and binds to β2-adrenergic receptors (β2AR) on microglia without altering the expression of these receptors (P = 0.9137), but instead inhibiting their activity. It was also observed that when β2AR was engaged in microglia, PAGly suppressed the release of TNF-α (P = 0.0018), IL-1β (P = 0.0310), and IL-6 (P = 0.0017), thereby reducing neuronal apoptosis (P = 0.000003). Furthermore, the protective effect of PAGly diminished after the administration of β2AR-specific agonist fenoterol (P = 0.0055). These data indicate that PAGly mitigates cerebral I/R injury by inhibiting microglial inflammation via β2AR, highlighting its potential as a therapeutic agent. These findings position PAGly as a promising candidate for therapeutic intervention in cerebrovascular injuries, warranting further exploration in clinical settings.

Natural products have perennially served as a cornerstone for the genesis of novel medicinal compounds. Most clinical therapeutics originate from ancestral herbal remedies and their formulations. Scholars and practitioners have always aimed to extract better remedies to treat various ailments. Genus Ficus, consisting of over 800 varieties, is a substantial tree native to tropical regions, characterized by its deciduous or evergreen nature. Various parts of this plant, including its bark, roots, leaves, fruit, and latex, find extensive use in treating a multitude of ailments. This review aims to update the ethnopharmacology, chemistry, and potential clinical applications of extracts and active ingredients from the ten most prevalent Ficus species. Major databases like Chemical Abstracts, ScienceDirect, SciFinder, PubMed, Scopus, etc. have all been used to generate references for this review. According to a thorough review of the literature, the many species of Ficus have a wide range of biological properties, including antioxidant, cytotoxic, antibacterial, antiviral, antifungal, anti-inflammatory, antiallergenic, antiasthmatic, larvicidal, antiplasmodial, antidiabetic, hepatoprotective and cardioprotective activity. A bunch of different secondary metabolites, such as flavonoids, saponins, alkaloids, tannins, phenolic acids, phytosterols, etc., were also reported, which can be responsible for exerted medicinal actions as well as play a crucial role in the field of new drug discovery and development. However, most species are missing well-controlled and double-blind clinical investigations. Thus, we still recommend further extensive exploration of this miraculous genus.

With the accumulation of knowledge on aging, people have gradually realized that among the many factors that cause individual aging, the accumulation of aging cells is an essential cause of organ degeneration and, ultimately, age-related diseases. Most cells present in the bone microenvironment gradually age over time, leading to an imbalance of osteogenesis, osteoclastogenesis, adipogenesis, and chondrogenesis. This imbalance contributes to age-related bone loss and the development of age-related bone diseases, such as osteoporosis. Bone aging can prolong the lifespan and delay the development of age-related diseases. Nanoparticles have controllable and stable physical and chemical properties and can precisely target different tissues and organs. By preparing multiple easily modified and biocompatible nanoparticles as different drug delivery carriers, specifically targeting various diseased tissues for controlled-release and sustained-release administration, the delivery efficiency of drugs can be significantly improved, and the toxicity and side effects of drugs can be substantially reduced, thereby improving the therapeutic effect of age-related bone diseases. In addition, other novel anti-aging strategies (such as stem cell exosomes) also have significant scientific and practical significance in anti-aging research on age-related bone diseases. This article reviews the research progress of various nano-drug-loaded particles and emerging anti-aging methods for treating age-related bone diseases, offering new insights and directions for precise targeted clinical therapies.
随着衰老知识的不断积累,人们逐渐认识到,在导致个体衰老的诸多因素中,衰老细胞的积累是器官退化并最终导致老年相关疾病的重要原因。存在于骨骼微环境中的大多数细胞会随着时间的推移逐渐衰老,从而导致骨生成、破骨细胞生成、脂肪生成和软骨生成的失衡。这种失衡会导致与年龄相关的骨质流失,并引发与年龄相关的骨病,如骨质疏松症。骨骼老化可以延长寿命,延缓老年性疾病的发生。纳米粒子具有可控、稳定的物理和化学特性,可精确靶向不同的组织和器官。通过制备多种易修饰、生物相容性好的纳米颗粒作为不同的给药载体,特异性地靶向各种病变组织进行控释和缓释给药,可显著提高药物的给药效率,大幅降低药物的毒性和副作用,从而提高老年性骨病的治疗效果。此外,其他新型抗衰老策略(如干细胞外泌体)在老年相关骨病的抗衰老研究中也具有重要的科学和现实意义。本文综述了各种纳米载药颗粒和新兴抗衰老方法治疗老年性骨病的研究进展,为临床精准靶向治疗提供了新的见解和方向。

The increasing prevalence of Anabolic–androgenic steroids (AAS) among women, driven by the pursuit of improved body aesthetics, characterized by higher lean mass and reduced adipose tissue, raises significant health concerns, particularly due to the limited knowledge regarding their effects on the female organism. Prolonged use and/or high doses of AAS are linked to various harmful side effects, including mood changes, psychiatric disorders, voice deepening, clitoromegaly, menstrual irregularities, and cardiovascular complications, prompting medical societies to discourage their widespread use due to insufficient evidence supporting their safety and efficacy. Studies in female rodents have shown that AAS can lead to increased aggression, inflammation, reduced neuronal density, and negative impacts on the myocardium and blood vessels. Additionally, maternal administration of androgens during pregnancy can adversely affect offspring’s reproductive, neuronal, and metabolic health, resulting in long-term impairments. The complexity of the mechanisms underlying AAS effects, and their potential genotoxicity remains poorly understood. This review aims to elucidate the various ways in which AAS can impact female physiology and that of their offspring, highlight commonly used anabolic substances, and discuss the positions of medical societies regarding AAS use.
女性越来越普遍地使用合成代谢雄性类固醇(AAS),这是由于她们追求以增加瘦体重和减少脂肪组织为特征的身体美感,这引起了人们对健康的极大关注,特别是由于人们对其对女性机体的影响了解有限。长期使用和(或)高剂量的 AAS 与各种有害的副作用有关,包括情绪变化、精神失常、声音加深、阴蒂肥大、月经不调和心血管并发症,由于没有足够的证据支持其安全性和有效性,医学协会不鼓励广泛使用。对雌性啮齿动物的研究表明,AAS 可导致攻击性增强、炎症、神经元密度降低以及对心肌和血管的负面影响。此外,母体在怀孕期间服用雄激素会对后代的生殖、神经元和新陈代谢健康产生不利影响,导致长期损害。人们对 AAS 作用机制的复杂性及其潜在的基因毒性仍然知之甚少。本综述旨在阐明 AAS 影响女性及其后代生理机能的各种方式,重点介绍常用的同化物质,并讨论医学会对使用 AAS 的立场。

Itraconazole (ITZ) is a highly effective antifungal agent. However, its oral application is associated with systemic toxicity and poor topical use. The present study aims to improve the antifungal activity of ITZ by loading it into bioadhesive niosomes. This approach is considered to enhance the ocular permeation of ITZ, thereby boosting its efficacy against fungal infections. Therefore, it was encapsulated into niosomes (F1) and subsequently coated with hyaluronic acid (HA; F2), chitosan (CS; F3), or a bilayer of CS/HA (F4). In addition, they were further incorporated into pH-sensitive in situ gels. This dual approach is expected to increase the amount of corneal-permeated ITZ, facilitating more effective management of ocular fungal infection.
Firstly, the niosomes were prepared by hydrating proniosomes using span 60, cholesterol, and phospholipid. ITZ-niosomes showed an increase in vesicle size from 165.5 ± 3.4 (F1) to 378.2 ± 7.2 nm (F3). The zeta potential varied within −20.9 ± 2.1 (F1), −29.5 ± 3.1 (F2), 32.3 ± 1.9 (F3), and 22.6 ± 1.3 mV (F4). The high EE% values ranged from 78.1 ± 2.2 % to 86.6 ± 2.9 %. Regarding ITZ release, F1 demonstrated a high release profile, whereas bioadhesive niosomes showed sustained release patterns. Furthermore, in situ gels containing niosomes displayed excellent gelling capacity and viscosity. Remarkably, F3 laden-in situ gels (F3-ISG) demonstrated the highest ex vivo corneal permeability of ITZ and antifungal activity with a safety effect. These results indicate that F3-ISG presents a promising strategy for boosting the ocular delivery of ITZ, that could help in treating ocular fungal infections.
伊曲康唑(ITZ)是一种高效的抗真菌剂。然而,其口服应用具有全身毒性,局部使用效果不佳。本研究旨在通过将伊曲康唑装入生物粘附性iosomes 来提高其抗真菌活性。这种方法被认为能增强 ITZ 的眼部渗透,从而提高其对真菌感染的疗效。因此,先将 ITZ 包封在 niosomes(F1)中,然后用透明质酸(HA;F2)、壳聚糖(CS;F3)或 CS/HA 双层(F4)包覆。此外,它们还被进一步加入对 pH 值敏感的原位凝胶中。这种双重方法有望增加角膜渗透 ITZ 的数量,从而更有效地治疗眼部真菌感染。首先,使用 span 60、胆固醇和磷脂水合原代物,制备出了新生物体。ITZ-niosomes的囊泡尺寸从165.5 ± 3.4(F1)增至378.2 ± 7.2 nm(F3)。zeta 电位在 -20.9 ± 2.1 (F1)、-29.5 ± 3.1 (F2)、32.3 ± 1.9 (F3) 和 22.6 ± 1.3 mV (F4) 范围内变化。高 EE% 值从 78.1 ± 2.2 % 到 86.6 ± 2.9 % 不等。在 ITZ 释放方面,F1 显示出较高的释放曲线,而生物黏附性iosomes 则显示出持续释放模式。此外,含有niosomes的原位凝胶显示出优异的胶凝能力和粘度。值得注意的是,含有 F3 的原位凝胶(F3-ISG)显示出最高的 ITZ 体内外角膜渗透性和抗真菌活性,并具有安全效应。这些结果表明,F3-ISG 是促进 ITZ 眼部给药的一种有前途的策略,有助于治疗眼部真菌感染。

Objectives

To perform a budget impact analysis (BIA) of the adoption of baricitinib for the management of alopecia areata (AA) by a Saudi public sector payer.

Methods

A BIA model was developed to calculate the expected financial impact under two scenarios: the baseline scenario, which reflects the current mix of treatments without baricitinib, and the projected scenario, in which baricitinib is adopted. The model assumed that patients with severe AA and those with mild-to-moderate AA who did not respond to other treatments were eligible for baricitinib treatment. The model input was based on published evidence, expert opinions, and the Saudi Expert Consensus Statement on the Diagnosis and Management of AA.

Results

Assuming a hypothetical total eligible population of 368 patients received different AA treatments over the 12-months study period. The aggregated 5-years cost in the baseline scenario was SR 5,836,616. Upon the introduction of baricitinib as an alternative treatment for severe AA, the projected aggregated budget impact was SR 7,473,138. Sensitivity analysis showed that the results were most sensitive to AA prevalence, percentage of severe AA, and predicted market share for baricitinib over the 5-year time horizon.

Conclusion

The addition of baricitinib to formularies is likely to increase the cost impact from a government hospital perspective. However, this addition expands the treatment options for patients with AA and may result in improved outcomes. Future cost-effectiveness analyses are recommended to estimate the cost per incremental improvement in the outcomes.
方法建立了一个预算影响分析模型,以计算两种情况下的预期财务影响:基线情况(反映了目前没有巴利替尼的治疗组合)和预测情况(采用巴利替尼)。该模型假设重度 AA 患者和对其他治疗无效的轻度至中度 AA 患者有资格接受巴利替尼治疗。模型输入基于已发表的证据、专家意见和《沙特 AA 诊断和管理专家共识声明》。结果假设符合条件的总人数为 368 人,在 12 个月的研究期内接受了不同的 AA 治疗。基线方案的 5 年总费用为 5,836,616 沙特里亚尔。在引入巴利替尼作为重症 AA 的替代治疗方法后,预计的预算影响总额为 7,473,138 沙特里亚尔。敏感性分析表明,结果对 AA 患病率、严重 AA 的百分比以及巴利替尼在 5 年时间跨度内的预测市场份额最为敏感。不过,这增加了 AA 患者的治疗选择,可能会改善治疗效果。建议今后进行成本效益分析,以估算疗效每增加一项改善所需的成本。

Introduction

Evolocumab’s short-term efficacy and safety were proven in phase-3 clinical trial, but its long-term safety and effectiveness in the Saudi population are yet to be studied. The aim of this study was to assess the long-term safety and effectiveness of evolocumab in Saudi patients with primary hypercholesterolemia or mixed dyslipidemia.

Method

A retrospective cohort study evaluated adult patients who had newly been prescribed evolocumab for hypercholesterolemia or mixed dyslipidemia. Safety events included myocardial infarction, unstable angina, stroke, transient ischemic attack, heart failure, rhabdomyolysis, renal dysfunction, and myalgia. Effectiveness outcomes included changes in lipid profiles from baseline, assessed at 6-, 12-, 18-, and 24-month.

Results

The study sample were 469 who newly prescribed evolocumab, from which 69.1 % being male, were included. The most prevalent comorbidities were coronary artery disease, diabetes, and hypertension. Statin was the most commonly used therapy. The most common adverse events at 6-month follow-up, based on the incidence rate per 1000 person-years, were coronary revascularization (63.20), myalgia (44.96), myocardial infarction (31.53), unstable angina (31.49), heart failure (26.94), rhabdomyolysis without renal dysfunction (8.93), transient ischemic attack (4.46), and rhabdomyolysis with renal dysfunction (4.46). Stroke incidence increased with follow-up length, from 8.87 per 1000 person-years at 6 months to 12.84 per 1000 person-years at 24 months. Evolocumab use significantly reduced LDL and total cholesterol levels at 6, 12, 18, and 24 months follow-up, while having no significant effect on HDL or triglycerides levels.

Conclusion

Evolocumab appeared to be safe and effective therapeutic option for patients with primary hypercholesterolemia or mixed dyslipidemia to potentially reduce LDL levels to therapeutic levels when statins are insufficient.
导言依维莫司单抗的短期疗效和安全性已在第三阶段临床试验中得到证实,但其在沙特人群中的长期安全性和有效性仍有待研究。本研究旨在评估 evolocumab 在沙特原发性高胆固醇血症或混合型血脂异常患者中的长期安全性和有效性。安全性事件包括心肌梗死、不稳定型心绞痛、中风、短暂性脑缺血发作、心力衰竭、横纹肌溶解症、肾功能障碍和肌痛。疗效结果包括血脂状况与基线相比的变化,分别在6个月、12个月、18个月和24个月进行评估。最常见的合并症是冠心病、糖尿病和高血压。他汀类药物是最常用的疗法。根据每千人年的发病率,随访6个月时最常见的不良事件是冠状动脉血运重建(63.20)、肌痛(44.96)、心肌梗死(31.53)、不稳定型心绞痛(31.49)、心力衰竭(26.94)、无肾功能障碍的横纹肌溶解(8.93)、短暂性脑缺血发作(4.46)和伴有肾功能障碍的横纹肌溶解(4.46)。中风发病率随着随访时间的延长而增加,从6个月时的每1000人年8.87例增加到24个月时的每1000人年12.84例。结论对于原发性高胆固醇血症或混合型血脂异常患者来说,使用伊沃洛单抗似乎是一种安全有效的治疗选择,当他汀类药物不足以降低低密度脂蛋白水平至治疗水平时,伊沃洛单抗有可能降低低密度脂蛋白水平至治疗水平。

Cytochrome c is a vital electron carrier in the mitochondrial respiratory chain. When the outer membrane of mitochondria becomes permeable, cytochrome c is discharged into the cytoplasm, where it initiates the intrinsic apoptosis pathway. The complex interaction between cytochrome c and apoptosis protease-activating factor-1 (Apaf-1) leads to the formation of the apoptosome and activation of a cascade of caspases, highlighting the critical role of cytochrome c in controlling cell death mechanisms. Additionally, cytochrome c undergoes post-translational modifications, especially phosphorylation, which intricately regulate its roles in both respiration and apoptosis. These modifications add layers of complexity to how cytochrome c effectively controls cellular functions. cytochrome c becomes a lighthouse in the intricate web of cancer, its expression patterns providing hints about prognosis and paths toward treatment. Reduced levels of cytochrome c have been observed in cancer tissues, indicating a potential inhibition of apoptosis. For instance, in glioma tissues, cytochrome c levels were lower compared to healthy tissues, and this reduction became more pronounced in advanced stages of the disease. However, the role of cytochrome c in cancer becomes more intricate as it becomes intertwined with the metabolic reprogramming of cancer cells. This suggests that cytochrome c plays a crucial role in tumor progression and resistance to treatment. Viewing cytochrome c as a molecular mosaic reveals that it is not merely a protein, but also a central player in determining cellular fate. This realization opens up exciting avenues for potential advancements in cancer diagnosis and treatment strategies. Despite the advancements made, the narrative surrounding cytochrome c remains incomplete, urging further exploration into its complexities and the biological implications linked to cancer. cytochrome c stands as a beacon of hope and a promising target for therapy in the battle against cancer, particularly due to its significant involvement in tumor metabolism. It holds the potential for a future where innovative solutions can be developed to address the intricate challenges of cellular fate. In this review, we have endeavored to illuminate the multifaceted domain of cytochrome c drawing connections among apoptosis, metabolic reprogramming, and the Warburg effect in the context of cancer.
细胞色素 c 是线粒体呼吸链中的重要电子载体。当线粒体外膜发生渗透时,细胞色素 c 就会被释放到细胞质中,从而启动内在凋亡途径。细胞色素 c 与凋亡蛋白酶激活因子-1(Apaf-1)之间的复杂相互作用导致凋亡小体的形成和 caspases 级联反应的激活,从而凸显了细胞色素 c 在控制细胞死亡机制中的关键作用。此外,细胞色素 c 还会发生翻译后修饰,特别是磷酸化,从而错综复杂地调节其在呼吸和细胞凋亡中的作用。这些修饰使细胞色素 c 如何有效控制细胞功能变得更加复杂。细胞色素 c 成为癌症复杂网络中的灯塔,其表达模式为预后和治疗提供了提示。在癌症组织中观察到细胞色素 c 水平降低,这表明细胞凋亡可能受到抑制。例如,在胶质瘤组织中,细胞色素 c 的水平比健康组织低,这种降低在疾病晚期更为明显。然而,细胞色素 c 在癌症中的作用变得更加复杂,因为它与癌细胞的代谢重编程交织在一起。这表明,细胞色素 c 在肿瘤进展和抗药性方面起着至关重要的作用。将细胞色素 c 看作分子马赛克揭示了它不仅仅是一种蛋白质,还是决定细胞命运的核心角色。这一认识为癌症诊断和治疗策略的潜在进步开辟了令人兴奋的途径。尽管取得了进展,但围绕细胞色素 c 的叙述仍不完整,这就需要进一步探索其复杂性以及与癌症相关的生物学意义。细胞色素 c 是抗击癌症的希望灯塔和有前途的治疗目标,特别是因为它在肿瘤代谢中的重要作用。在未来,细胞色素 c 具有开发创新解决方案的潜力,以应对细胞命运的复杂挑战。在这篇综述中,我们试图阐明细胞色素 c 的多面性,并在癌症的背景下将细胞凋亡、新陈代谢重编程和沃伯格效应联系起来。
