Cellular and subcellular metabolic activities are crucial processes involved in the regulation of intracellular homeostasis, including cellular and subcellular signaling pathways. Dysregulation of intracellular regulation mechanisms is catastrophic and cumulates into cell death. To overcome the issue of dysregulation of intracellular regulation mechanisms, the preservation of subcellular and extracellular components is essential to maintain healthy cells with increased longevity. Several physiopathological changes occur during cell ageing, one of which is the dysregulation of intracellular physiology of the oxidative phosphorylation process. Nicotinamide mononucleotide (NMN) remains in the debut of anti-aging therapeutic effect. Aged myocardiocyte characterized by disrupted NMN and or its precursors or signaling pathways. Simultaneously, several other pathophysiological occur that collectively impair intracellular homeostasis. The NMN role in the antiaging effect remains unclear and several hypotheses have been introduced into describing the mechanism and the potential outcomes from NMN exogenous supply. Correction of the impaired intracellular homeostasis includes correction to the NMN metabolism. Additionally, autophagy correction, which is the key element in the regulation of intracellular intoxication, including oxidative stress, unfolding protein response, and other degradation of intracellular metabolites. Several signaling pathways are involved in the regulation mechanism of NMN effects on myocardiocyte health and further longevity. NMN protects myocardiocytes from ischemic injury by reducing anabolism and, increasing catabolism and further passing the myocardiocytes into dormant status. NMN applications include ischemic heart, disease, and failed heart, as well as dilated cardiomyopathies. Cytosolic and mitochondrial NADPH are independently functioning and regulating. Each of these plays a role in the determination of the longevity of the myocardiocytes. NMN has a cornerstone in the functionality of Sirtuins, which are an essential anti-senescent intrinsic molecule. The study aims to assess the role of NMN in the longevity and antisenescent of myocardiocytes.

细胞和亚细胞代谢活动是调节细胞内平衡的关键过程,包括细胞和亚细胞信号通路。细胞内调节机制失调是灾难性的,会导致细胞死亡。要解决细胞内调节机制失调的问题,就必须保护亚细胞和细胞外成分,以保持细胞健康并延长其寿命。细胞老化过程中会发生几种生理病理变化,其中之一就是氧化磷酸化过程的细胞内生理失调。烟酰胺单核苷酸(NMN)仍然是抗衰老治疗效果的首次亮相。衰老心肌细胞的特点是 NMN 及其前体或信号通路紊乱。与此同时,其他一些病理生理现象也会共同损害细胞内的平衡。NMN 在抗衰老效应中的作用仍不明确,已有几种假设用于描述 NMN 外源供应的机制和潜在结果。纠正受损的细胞内稳态包括纠正 NMN 代谢。此外,自噬纠正是调节细胞内中毒的关键因素,包括氧化应激、折叠蛋白反应和细胞内代谢物的其他降解。NMN 对心肌细胞健康和进一步延年益寿的调节机制涉及多个信号通路。NMN 通过减少合成代谢、增加分解代谢和进一步使心肌细胞进入休眠状态,保护心肌细胞免受缺血性损伤。NMN 的应用包括缺血性心脏、疾病、衰竭性心脏以及扩张型心肌病。细胞质和线粒体中的 NADPH 具有独立的功能和调节作用。它们各自在决定心肌细胞寿命方面发挥作用。NMN 是 Sirtuins 功能的基石,而 Sirtuins 是一种重要的抗衰老内在分子。本研究旨在评估 NMN 在心肌细胞长寿和抗衰老方面的作用。

Colorectal cancer (CRC) has a high incidence and fatality rate worldwide. It ranks second concerning death worldwide. Cancer patients are diagnosed with the disease at a later stage due to the absence of early diagnostic methods, which leads to increased death. With the help of recent advancements in the fields of diagnosis and therapy, the development of novel methods using new targets could be helpful for the long-term survival of CRC patients when CRC is detected early. However, the prognosis for the advanced stage of CRC is abysmal. New biomarkers are emerging as promising alternatives since they can be utilized for early detection of CRC, are simple to use, and non-invasive. Non-coding RNAs (ncRNAs) have been seen to have an aberrant expression in the development of many malignancies, including CRC. In the past two decades, much research has been done on non-coding RNAs, which may be valuable as biomarkers and targets for antitumor therapy. Non-coding RNAs can be employed in detecting and treating CRC. Non-coding RNAs play an essential role in regulating gene expression. This article reviews ncRNAs and their expression levels in CRC patients that could be used as potential biomarkers. Various ncRNAs have been associated with CRC, such as microRNAs, long non-coding RNAs, circular RNAs, etc. The expression of these non-coding RNAs may provide insights into the stages of cancer and the prognosis of cancer patients and therefore proper precautionary measures can be taken to decrease cancer-related deaths.

结肠直肠癌(CRC)在全球的发病率和死亡率都很高。它在全球死亡病例中排名第二。由于缺乏早期诊断方法,癌症患者被诊断出患病的时间较晚,导致死亡人数增加。随着诊断和治疗领域的最新进展,利用新靶点开发新方法有助于早期发现 CRC 患者的长期生存。然而,晚期 CRC 的预后非常糟糕。新的生物标记物正在成为有希望的替代方法,因为它们可用于早期检测 CRC,使用简单且无创。非编码 RNA(ncRNA)在许多恶性肿瘤(包括 CRC)的发病过程中都有异常表达。在过去二十年中,人们对非编码 RNA 进行了大量研究,这些 RNA 可能是有价值的生物标志物和抗肿瘤治疗靶标。非编码 RNA 可用于检测和治疗 CRC。非编码 RNA 在调控基因表达方面发挥着重要作用。本文综述了非编码 RNA 及其在 CRC 患者中的表达水平,这些非编码 RNA 有可能成为潜在的生物标记物。有多种 ncRNA 与 CRC 相关,如 microRNA、长非编码 RNA、环状 RNA 等。这些非编码 RNA 的表达可能有助于了解癌症的分期和癌症患者的预后,从而采取适当的初步措施减少与癌症相关的死亡。

Autophagy plays a crucial role in maintaining endothelial cell homeostasis through the turnover of intracellular components during stress conditions in a lysosomal-dependent manner. The regeneration strategy involves several aspects, including autophagy. Autophagy is a catabolic degenerative lysosomal-dependent degradation of intracellular components. Autophagy modifies cellular and subcellular endothelial cell functions, including mitochondria stress, lysosomal stress, and endoplasmic reticulum unfolded protein response. Activation of common signaling pathways of autophagy and regeneration and enhancement of intracellular endothelial cell metabolism serve as the bases for the induction of endothelial regeneration. Endothelial progenitor cells include induced pluripotent stem cells (iPSC), embryonic stem cells, and somatic cells, such as fibroblasts. Future strategies of endothelial cell regeneration involve the induction of autophagy to minimize the metabolic degeneration of the endothelial cells and optimize the regeneration outcomes.

自噬通过在应激条件下以溶酶体依赖的方式转换细胞内成分,在维持内皮细胞稳态方面发挥着至关重要的作用。再生策略涉及几个方面,包括自噬。自噬是细胞内成分的分解代谢变性溶酶体依赖性降解。自噬改变细胞和亚细胞内皮细胞的功能,包括线粒体应激、溶酶体应激和内质网未折叠蛋白反应。激活自噬和再生的常见信号通路以及增强细胞内内皮细胞代谢是诱导内皮再生的基础。内皮祖细胞包括诱导多能干细胞(iPSC)、胚胎干细胞和体细胞,如成纤维细胞。内皮细胞再生的未来策略包括诱导自噬,以最大限度地减少内皮细胞的代谢退化并优化再生结果。

Environmental factors like UV radiation and epigenetic changes are significant factors for skin cancer that trigger early aging. This review provides essential information on cancer development concerning aging, the receptors involved, and the therapeutic targets. Biopolymers like polysaccharide, polyphenols, proteins, and nucleic acid plays a vital role in the regulation of normal cell homeostasis. Therefore, it is pertinent to explore the role of biopolymers as antiaging formulations and the possibility of these formulations being used against cancer via topical administrations. As UV radiation is one of the predominant factors in causing skin cancer, the association of receptors between aging and cancer indicated that insulin receptor, melatonin receptor, toll-like receptor, SIRT 1 receptor, tumor-specific T cell receptor and mitochondria-based targeting could be used to direct therapeutics for suppression of cancer and prevent aging. Biopolymer-based nanoformulations have tremendously progressed by entrapment of drugs like curcumin and resveratrol which can prevent cancer and aging simultaneously. Certain protein signaling or calcium and ROS signaling pathways are different for cancer and aging. The involvement of mitochondrial DNA mutation along with telomere shortening with a change in cellular energetics leading to genomic instability in the aging process can also induce mitochondrial dysfunction and epigenetic alterations leading to skin cancer. Therefore, the use of biopolymers as a topical supplement during the aging process can result in the prevention of cancer.

紫外线辐射和表观遗传变化等环境因素是诱发皮肤癌的重要因素,这些因素会引发早期衰老。本综述提供了与衰老有关的癌症发展、相关受体和治疗靶点的基本信息。多糖、多酚、蛋白质和核酸等生物聚合物在调节正常细胞稳态方面发挥着重要作用。因此,探索生物聚合物作为抗衰老制剂的作用,以及这些制剂通过局部用药抗癌的可能性是非常有意义的。由于紫外线辐射是导致皮肤癌的主要因素之一,衰老与癌症之间的受体关联表明,胰岛素受体、褪黑激素受体、类收费受体、SIRT 1 受体、肿瘤特异性 T 细胞受体和线粒体靶向可用于指导抑制癌症和防止衰老的疗法。以生物聚合物为基础的纳米制剂已取得巨大进步,其中夹带的姜黄素和白藜芦醇等药物可同时预防癌症和衰老。癌症和衰老的某些蛋白质信号或钙和 ROS 信号通路是不同的。在衰老过程中,线粒体 DNA 变异、端粒缩短、细胞能量变化导致基因组不稳定,也会诱发线粒体功能障碍和表观遗传学改变,从而导致皮肤癌。因此,在衰老过程中使用生物聚合物作为局部补充剂可以预防癌症。

Background: Aging and gender are risk factors for urine incontinence, which can lead to psychological, physical, and social complications.

Objective: This community-based study investigates the effectiveness of pelvic floor muscle training on the severity and quality of urine incontinence and social participation of older women.

Methods: This quasi-experimental community-based study was performed with the participation of 60 older women referring to the Public Health Center in Kerman City, southern Iran. The experiment group was trained with pelvic floor muscle training in 7 training sessions with distance health education in the second half of 2021. Before and after the intervention, data were collected based on: demographic, severity and quality of urine incontinence, and social participation inventories. Data were analyzed using a t-test and ANOVA (P ≤ 0.05).

Results: The mean scores of severity and quality of urine incontinence and social participation in the experiment and control groups before receiving the intervention were not statistically significant (P ≥ 0.05). But after that, a statistically significant difference was observed between the groups (P <0.05), which showed an improvement in the severity and quality of urine incontinence scores as well as SP in the experiment group.

Conclusions: Tele-training of the Kegel exercise, even during the pandemic, can play an important role in improving incontinence and social participation in older women. Therefore, this training can be used to prevent and improve urine incontinence in public health centers in the community.

Background: Chlorpyrifos (CPF) is an organophosphate pesticide that inhibits acetylcholinesterase (AChE) activity. Investigations have also focused on its neurotoxicity, which is independent of AChE inhibition. Here, we evaluated the effect of CPF on oxidative indices in the brain tissue and explored the protective effect of curcumin (Cur) against its toxicity.

Methods: Forty male Wistar rats were divided into five groups, each consisting of eight rats (n = 8) per group. Animals were administrated by oral gavage for 90 days with the following treatments: control (C), CPF, CPF + CUR 25 mg/kg, CPF + CUR50, and CPF + cur 100 received olive oil, CPF, CPF plus 25 mg/kg of CUR, CPF plus 50 mg/kg of CUR, and CPF plus 100 mg/kg of CUR, respectively. After anesthetization, animal brain tissues were obtained for assessment of oxidative stress indices.

Results: The concentration of MDA significantly increased in the brains of the CPF group as compared to the control group (p < 0.01). Also, a significant decrease in MDA concentrations was observed in the brains of rats in the CPF + Cur 100 group compared to the CPF group (p < 0.05). A significant decrease was noted in the GSH concentration in the brains of the CPF group compared to the control group (p < 0.05). Treatment with Cur at 100 mg/kg exhibited a significant increase in GSH concentrations in the brains of the CPF-exposed group compared to the CPF group without Cur administration (p < 0.05). The concentration of NO exhibited a significant increase in the brains of the CPF group when compared to the control group (p < 0.05). Also, a significant decrease in NO concentration was observed in the brain tissue of the CPF + Cur 100 group compared to the CPF group (p < 0.05).

Conclusion: Our data establish that chronic exposure to CPF induced oxidative stress in brain tissue, which was reversed by CUR administration. Additional experimental and clinical investigations are needed to validate the efficacy of CUR as a potential antidote for CPF poisoning.

背景:毒死蜱(CPF)是一种有机磷农药,可抑制乙酰胆碱酯酶(AChE)的活性。研究还重点关注其神经毒性,这种毒性与乙酰胆碱酯酶抑制作用无关。在此,我们评估了氯化石蜡对脑组织氧化指数的影响,并探讨了姜黄素(Cur)对其毒性的保护作用:方法:将 40 只雄性 Wistar 大鼠分为 5 组,每组 8 只(n = 8)。动物通过口服以下处理 90 天:对照组(C)、CPF、CPF + CUR 25 mg/kg、CPF + CUR50 和 CPF + cur 100 分别接受橄榄油、CPF、CPF + CUR 25 mg/kg、CPF + CUR 50 mg/kg 和 CPF + CUR 100 mg/kg。麻醉后,获取动物脑组织以评估氧化应激指数:结果:与对照组相比,氯化石蜡组大脑中的 MDA 浓度明显升高(p < 0.01)。此外,与 CPF 组相比,CPF + Cur 100 组大鼠大脑中的 MDA 浓度明显下降(p < 0.05)。与对照组相比,氯化石蜡组大鼠大脑中的 GSH 浓度明显下降(p < 0.05)。与未施用 Cur 的氯化石蜡组相比,施用 100 毫克/千克 Cur 的氯化石蜡组大脑中的 GSH 浓度明显增加(p < 0.05)。与对照组相比,氯化石蜡暴露组大脑中的 NO 浓度明显增加(p < 0.05)。此外,与氯化石蜡组相比,氯化石蜡 + Cur 100 组脑组织中的 NO 浓度明显下降(p < 0.05):我们的数据证实,长期暴露于 CPF 会诱发脑组织氧化应激,而服用 CUR 可逆转这种应激。要验证 CUR 作为氯化石蜡中毒潜在解毒剂的疗效,还需要更多的实验和临床研究。

Background: The incidence of elderly people experiencing falls is currently increasing, which results in serious medical issues, such as fear of falling, limited physical activity, disability, and bone fractures, especially hip fractures. This study aimed to investigate balancing ability using a multi-directional reach test (MDRT) in older adults with and without diabetes mellitus.

Methods: 72 older adults with and without diabetes mellitus were recruited, and divided into two groups, including older adults without diabetes mellitus (n = 36) and older adults with diabetes mellitus (n = 36). All subjects completed all directions of the MDRT.

Results: There were no significant differences in MDRT scores in all directions between the two groups (p>0.05). Both groups achieved the highest MDRT scores in the forward direction. In contrast, the two groups had the lowest scores of MDRT in a backward direction. Furthermore, older adults with diabetes mellitus had lower MDRT scores in all directions than older adults without diabetes mellitus.

Conclusion: The current study indicated that MDRT could be used to investigate the ability of balance in individuals with diabetes mellitus.

背景:目前,老年人跌倒的发生率越来越高,这导致了严重的医疗问题,如害怕跌倒、体力活动受限、残疾和骨折,尤其是髋部骨折。方法:招募 72 名患有和未患有糖尿病的老年人,将其分为两组,包括未患有糖尿病的老年人(36 人)和患有糖尿病的老年人(36 人)。所有受试者都完成了MDRT的所有方向:结果:两组受试者在所有方向的 MDRT 分数均无明显差异(P>0.05)。两组受试者在前进方向的 MDRT 分数都最高。相反,两组在后向的 MDRT 分数最低。此外,患有糖尿病的老年人在所有方向上的 MDRT 分数都低于未患糖尿病的老年人:本研究表明,MDRT 可用于调查糖尿病患者的平衡能力。

Neurodegenerative diseases, such as Alzheimer's, Parkinson's, and prion disease, are characterized by the conversion of normally soluble proteins or peptides into aggregated amyloidal fibrils. These diseases result in the permanent loss of specific types of neurons, making them incurable and devastating. Research on animal models of memory problems mentioned in this article contributes to our knowledge of brain health and functionality. Neurodegenerative disorders, which often lead to cognitive impairment and dementia, are becoming more prevalent as global life expectancy increases. These diseases cause severe neurological impairment and neuronal death, making them highly debilitating. Exploring and understanding these complex diseases offer significant insights into the fundamental processes essential for maintaining brain health. Exploring the intricate mechanisms underlying neurodegenerative diseases not only holds promise for potential treatments but also enhances our understanding of fundamental brain health and functionality. By unraveling the complexities of these disorders, researchers can pave the way for advancements in diagnosis, treatment, and ultimately, improving the lives of individuals affected by neurodegenerative diseases.

神经退行性疾病,如阿尔茨海默病、帕金森病和朊病毒病,其特征是正常的可溶性蛋白质或肽转化为聚集的淀粉样纤维。这些疾病会导致特定类型神经元的永久性丧失,因而是无法治愈的毁灭性疾病。本文提到的记忆问题动物模型研究有助于我们了解大脑的健康和功能。神经退行性疾病通常会导致认知障碍和痴呆症,随着全球人均寿命的延长,这种疾病正变得越来越普遍。这些疾病会导致严重的神经损伤和神经元死亡,使人极度衰弱。探索和了解这些复杂的疾病,有助于深入了解维持大脑健康所必需的基本过程。探索神经退行性疾病的复杂机制不仅有望找到潜在的治疗方法,还能增进我们对大脑基本健康和功能的了解。通过揭示这些疾病的复杂性,研究人员可以为诊断、治疗以及最终改善神经退行性疾病患者的生活铺平道路。

Background: Elderly people have multiple comorbidities that often require treatment with multiple medications. Having strategies to lessen the risks associated with pharmacological interactions and potentially inadequate prescribing (PIP) is of major importance. The STOPP- START criteria are useful in identifying PIP along with other tools, such as LASA (look alike/sound alike) drugs and high-risk medications (HRM).

Objective: We aimed to clinically and sociodemographically characterize the population with PIP according to the STOPP-START criteria in hospitalized elderly patients over 6 months in a third-level hospital in Colombia, South America. We also aimed to calculate the prevalence of PIP, LASA drugs and HRM and to identify other problems related with medication. Finally, we proposed an algorithm for the identification of PIP in this population.

Methods and materials: This was a descriptive, cross-sectional study in hospitalized patients older than 60 years during the first semester of 2021 to identify PIP according to STOPP- START criteria. An analysis of clinical and sociodemographic variables was conducted, as well as the construction of an algorithm to identify PIP in the elderly in a semiautomated way. Data were collected and analyzed using the software SPSS 2021, using descriptive statistics and measures of central tendency.

Results: The prevalence of PIP in the study population was 25%. Furthermore, 60% of patients had one problem related to medication, and 27% used at least one LASA drug or HRM.

Conclusion: This study allows one to characterize, for the first time, the Colombian population prone to PIP, as well as the construction of an algorithm that identifies PIP in a semiautomated way.

背景:老年人有多种并发症,通常需要使用多种药物进行治疗。如何降低药物相互作用和潜在处方不当(PIP)带来的风险至关重要。STOPP- START 标准以及其他工具,如 LASA(外观相似/声音相似)药物和高风险药物 (HRM),有助于识别 PIP:我们的目的是根据 STOPP-START 标准,从临床和社会人口学角度分析南美洲哥伦比亚一家三级医院 6 个月以上住院老年患者中 PIP 患者的特征。我们还旨在计算 PIP、LASA 药物和 HRM 的患病率,并找出与药物治疗有关的其他问题。最后,我们提出了一种在该人群中识别 PIP 的算法:这是一项描述性横断面研究,研究对象是 2021 年上半年住院的 60 岁以上患者,目的是根据 STOPP- START 标准识别 PIP。对临床和社会人口学变量进行了分析,并构建了一种半自动化识别老年人 PIP 的算法。数据的收集和分析采用了 SPSS 2021 软件,使用了描述性统计和中心倾向测量:研究人群中 PIP 的发病率为 25%。此外,60%的患者有一个与药物治疗相关的问题,27%的患者至少使用一种LASA药物或HRM:本研究首次描述了哥伦比亚易患 PIP 的人群特征,并构建了一种半自动识别 PIP 的算法。

Background: Aging is associated with the slowing down of metabolic processes, diminished physiological processes, changes in hormonal activity and increasing exposure to oxidative stress factors and chronic inflammation. The endocannabinoid system (ECS) is a major signaling network that plays a pro-homeostatic role in the central and peripheral organs of the human body. A class of minor lipids, N-acylethanolamines (NAEs), which do not activate cannabinoid receptors, except for anandamide, but can potentiate the action of endocannabinoids and have a wide spectrum of biological activity and significant adaptogenic potential, belongs to ECS. The results of different studies over the past decades have established the protective effect of NAE on many pathological conditions.

Objective: This study aimed to investigate the cardioprotective effects of C18:0 NAE- N-stearoylethanolamine (NSE) in aged rats. In this study, we focused on investigating the effects of C18:0 NAE- N-stearoylethanolamine (NSE) on the intensity of oxidative/ nitrosative stress, antioxidant potential, lipoprotein profile and inflammation markers of blood plasma, phospholipid composition and age-related morphological changes of old rat heart tissues.

Methods: The study was conducted on Sprague Dawley male laboratory rats. The three groups of rats were involved in the study design. The first group consisted of young rats aged 4 months (n=10). The second (n=10) and third (n=10) groups included old rats aged of 18 months. Rats from the third group were administered a per os aqueous suspension of NSE at a dose of 50 mg/kg of body weight daily for 10 days. All groups of rats were kept on a standard vivarium diet. The blood plasma, serum, and heart of rats were used for biochemical and histological analysis.

Results: The cardioprotective effect of N-stearoylethanolamine in old rats was established, which was expressed in the normalization of the antioxidant system condition and the level of proinflammatory cytokines, positive modulation of blood plasma and lipoprotein profile, normalization of heart tissue lipid composition, and significant reduction in age-related myocardium morphological changes.

Conclusion: The revealed effects of N-stearoylethanolamine can become the basis for developing a new drug for use in complex therapy to improve the quality of life of older people.

背景:衰老与新陈代谢过程减慢、生理过程减弱、荷尔蒙活动变化以及氧化应激因素和慢性炎症暴露增加有关。内源性大麻素系统(ECS)是一个重要的信号网络,在人体的中枢和外周器官中发挥着促进平衡的作用。N-acylethanolamines (NAEs)是一类次要脂质,属于 ECS 的一种,除 anandamide 外,NAEs 不会激活大麻素受体,但可以增强内源性大麻素的作用,具有广泛的生物活性和显著的适应潜力。目的:本研究旨在探讨 C18:0 NAE-Nstearoylethanolamine(NSE)对老年大鼠心脏的保护作用:本研究主要探讨了 C18:0 NAE-Nstearoylethanolamine(NSE)对老年大鼠血浆氧化/亚硝基应激强度、抗氧化潜能、脂蛋白谱和炎症标志物、磷脂组成以及与年龄相关的心脏组织形态学变化的影响:研究对象为 Sprague Dawley 雄性实验鼠。研究设计了三组大鼠。第一组是 4 个月大的幼鼠(n=10)。第二组(10 只)和第三组(10 只)包括 18 个月大的老老鼠。第三组的大鼠每天按体重 50 毫克/千克的剂量服用 NSE 水悬液,连续服用 10 天。所有组别大鼠均以标准饲养室饮食饲养。对大鼠的血浆、血清和心脏进行生化和组织学分析:结果:N-硬脂酰乙醇胺对老年大鼠心脏有保护作用,表现在抗氧化系统状况和促炎细胞因子水平正常化,血浆和脂蛋白谱有积极调节作用,心脏组织脂质成分正常化,与年龄相关的心肌形态学变化显著减少:结论:N-硬脂酰乙醇胺所揭示的作用可作为开发用于复合疗法的新药的基础,以改善老年人的生活质量。
