Clinical trial of arthroscopic debridement combined with functional exercise in the treatment of advanced knee osteoarthritis: A retrospective observational study.

Advanced knee osteoarthritis (KOA) impacts both knees, resulting in pain, deformity, and substantial restrictions in joint mobility. This study aims to examine the effectiveness of combining arthroscopic debridement with functional exercise in treating advanced KOA. A total of 296patients diagnosed with advanced KOA were divided into two groups: the observation group (n= 152) received arthroscopic debridement combined with functional exercise, while the control group (n= 144) underwent arthroscopic debridement only. The study compared and observed the outcomes between the two groups. There were no significant differences in knee joint function, inflammation level, and oxidative stress between the two groups before treatment (P> 0.05). Following treatment for six months, the observation group exhibited significantly lower visual analog scale (VAS) score, tissue inhibitors of metalloproteinase-1 (TIMP-1), tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), matrix metalloproteinase-3 (MMP-3), and malondialdehyde (MDA) levels compared to the control group (P< 0.05). Meanwhile, the observation group showed significantly higher levels of Lysholm score, hospital for special surgery (HSS) score, range of motion (ROM) of knee, peak torque (PT) and total work (TW) for knee extension and flexion, superoxide dismutase (SOD), total antioxidant capacity (T-AOC), and glutathione (GSH) compared to the control group (P< 0.05). Besides, the effective treatment rate in the observation group was notably higher than that in the control group (80.92% vs. 69.44%, P< 0.05). The combination of arthroscopic debridement with functional exercise is an effective treatment for advanced KOA. This approach not only enhances the function and strength of knee joint and reduces inflammatory response but also boosts the body's antioxidant capacity. The treatment exhibits encouraging outcomes and warrants broad implementation.

Dietary Zanthoxylum bungeanum leaf powder improves growth performance and antioxidant capacity via Nrf2/HO-1 signaling pathway in broilers.

This study focused on the effects of dietary Zanthoxylum bungeanum leaves (ZBL) powder on the growth performance and antioxidant capacity via the Nrf2/HO-1 signaling pathway in broilers. The experiment adopted a single-factor completely random design, and 440 healthy one-day-old AA broiler chicks were randomly divided into four groups: the control group (CON) was fed a corn-soybean meal-based diet, the CZ1 group was fed a basic diet with 1% ZBL powder, the CZ2 group fed a basic diet with 2% ZBL powder, and the CZ3 group fed a basic diet with 3% ZBL powder. The experiment was divided into the starter period (1-21 d) and the grower period (22-42 d). There were five replicates per group in the starter period, with 22 chickens per replicate. The same grouping as in the starter period was used in the grower period, with 20 chickens per replicate. The results showed that the addition of ZBL powder to the diet had no adverse effects on the growth performance and morphological structure of the intestine of broiler chickens in the CZ1 and CZ2 groups (P > 0.05). Compared with the control group, the diet with 1% and 2% ZBL powder significantly increased the antioxidant indicators such as CAT, T-AOC, and T-SOD in the serum and liver tissue of broiler chickens, it upregulated the related genes expression of nuclear factor erythroid derived-2/heme oxygenase-1 (Nrf2/HO-1) signaling pathway such as Nrf2, NQO1, HO-1, SOD1, and CAT in the jejunal mucosa and enhanced the expression of ZO-1 and OCLN genes in the jejunal mucosa (P < 0.05). In conclusion, dietary supplementation with 1% and 2% of ZBL powder into the daily diet can enhance the body's antioxidant capacity by elevating antioxidant levels in both serum and liver, upregulates the expression of genes associated with the Nrf2/HO-1 signaling pathway in the jejunal mucosa, and helps maintain the integrity of the intestinal mucosal barrier. The optimal addition level of ZBL powder in the diet was determined by quadratic regression analysis to be 1.36%-1.60% during days 1-21 and 1.14%-1.50% during days 22-42.

Orthobiologic Products: Preservation Options for Orthopedic Research and Clinical Applications.

The biological products used in orthopedics include musculoskeletal allografts-such as bones, tendons, ligaments, and cartilage-as well as biological therapies. Musculoskeletal allografts support the body's healing process by utilizing preserved and sterilized donor tissue. These allografts are becoming increasingly common in surgical practice, allowing patients to avoid more invasive procedures and the risks associated with donor site morbidity. Bone grafting is one of the most frequently used procedures in orthopedics and traumatology. Biologic approaches aim to improve clinical outcomes by enhancing the body's natural healing capacity and reducing inflammation. They serve as an alternative to surgical interventions. While preliminary results from animal studies and small-scale clinical trials have been promising, the field of biologics still lacks robust clinical evidence supporting their efficacy. Biological therapies include PRP (platelet-rich plasma), mesenchymal stem cells (MSCs)/stromal cells/progenitor cells, bone marrow stem/stromal cells (BMSCs), adipose stem/stromal cells/progenitor cells (ASCs), cord blood (CB), and extracellular vesicles (EVs), including exosomes. The proper preservation and storage of these cellular therapies are essential for future use. Preservation techniques include cryopreservation, vitrification, lyophilization, and the use of cryoprotective agents (CPAs). The most commonly used CPA is DMSO (dimethyl sulfoxide). The highest success rates and post-thaw viability have been achieved by preserving PRP with a rate-controlled freezer using 6% DMSO and storing other cellular treatments using a rate-controlled freezer with 5% or 10% DMSO as the CPA. Extracellular vesicles (EVs) have shown the best results when lyophilized with 50 mM or 4% trehalose to prevent aggregation and stored at room temperature.

Mood, Quality of Life, and Immune Fitness During the COVID-19 Pandemic of Young Adults in Germany.

Background: The COVID-19 pandemic has profoundly affected young adults' lives globally, including those in Germany. This study investigated mental health and quality of life during the pandemic, with a particular focus on mood. Immune fitness, the body's capacity to respond to health challenges (such as infections) by activating an appropriate immune response, was assessed as a physical health indicator. Methods: Data were collected from 317 participants, aged 18 to 35, via an online survey conducted between November 2021 and March 2022. Participants included 103 men (32.5%) and 214 women (67.5%), with a mean age of 25.5 years (SD = 4.1). Results: Compared to pre-pandemic levels, significant declines in mood, quality of life, immune fitness, and sleep quality were observed during the lockdown periods of the COVID-19 pandemic (p < 0.0125). The most pronounced effects were observed during the second lockdown, with declines extending into the second no-lockdown period for fatigue, depression, happiness, optimism, and immune fitness (p < 0.0125). Significant sex differences were found for the magnitude of mood effects (anxiety, depression, stress). No significant differences were found according to age or occupational status (student vs. work). Conclusions: The COVID-19 pandemic and associated lockdown periods had a significant negative effect on the mood, immune fitness, and well-being of young adults living in Germany.

Embodied agentive habits: between sedimentation and ongoing ground

Abstract This paper argues that human signification is governed by “agentive systems,” inspired by an extended framework that combines the Practical Logic of Cognitive Systems and Peircean semiotics. An agentive system encompasses both the efficient anticipation of resource utilization and the use of actual available resources, including bodily capacities in the form of embodied habits. These resources are allocated based on agendas (goals) pursued by human agents in their interactions with the environment. In this context, signification involves the meaning of actions embedded within their agentive system, encompassing the agent performing the actions, the action’s goal or agenda, and the available resources, whether bodily (skills, abilities, capacities) or non-bodily (objects, signs). After presenting the general framework in which the concept of an agentive system is approached, I develop a proposal drawing on insights from Göran Sonesson’s reflections on the importance of sedimentation and Lifeworld for semiotics. This proposal highlights how the acquisition of embodied habits facilitates and promotes the significance of cultural products, while their deployment allows for the emergence of situated signification.

Carboxymethyl chitosan-enhanced multi-level microstructured composite hydrogel scaffolds for bone defect repair

Critical-sized bone defects (CSBDs) necessitate interventions like bone grafts or tissue engineering scaffolds to surpass the body's limited spontaneous healing capacity and ensure effective bone regeneration. A multi-level microstructured composite hydrogel 3D scaffold was fabricated for enhanced bone defect repair, integrating a 3D-printed macroporous polylactic acid (PLA) scaffold with polydopamine treatment and filled with a sodium alginate/nano hydroxyapatite/carboxymethyl chitosan (SA/nHA/CMCS) micrometer-scale porous composite hydrogel. The incorporation of nano hydroxyapatite (nHA) nanoparticles enhanced hydrogel crosslinking and osteogenic activity. A systematic evaluation of CMCS concentration demonstrated its pivotal role in enhancing hydrogel cross-linking and mineralization, regulating degradation rate adapted to the osteogenic cycle, endowing the scaffold with a bioactive micrometer-scale porous structure. In vitro studies confirmed the osteogenic effectiveness of the composite hydrogel 3D scaffold, particularly those with CMCS, which boosted bone mesenchymal stem cells (BMSCs) adhesion, proliferation, and differentiation. The rabbit tibial bone defect model further confirmed that, compared to the DAPLA (dopamine modified PLA) scaffold, the bone trabecular number of the DSHC (DAPLA-SA/nHA/CMCS) scaffold increases 2.06-fold. In conclusion, this study expanded the application of hydrogel scaffolds in bone tissue engineering and provided an effective strategy for the development of hydrogel implant materials.

Oxidative stress: fundamentals and advances in quantification techniques.

Oxidative species, generated endogenously via metabolism or from exogenous sources, play crucial roles in the body. At low levels, these species support immune functions by participating in phagocytosis. They also aid in cellular signaling and contribute to vasomodulation. However, when the levels of oxidative species exceed the body's antioxidant capacity to neutralize them, oxidative stress occurs. This stress can damage cellular macromolecules such as lipids, DNA, RNA, and proteins, driving the pathogenesis of diseases and aging through the progressive deterioration of physiological functions and cellular structures. Therefore, the body's ability to manage oxidative stress and maintain it at optimal levels is essential for overall health. Understanding the fundamentals of oxidative stress, along with its reliable quantification, can enable consistency and comparability in clinical practice across various diseases. While direct quantification of oxidant species in the body would be ideal for assessing oxidative stress, it is not feasible due to their high reactivity, short half-life, and the challenges of quantification using conventional techniques. Alternatively, quantifying lipid peroxidation, damage products of nucleic acids and proteins, as well as endogenous and exogenous antioxidants, serves as appropriate markers for indicating the degree of oxidative stress in the body. Along with the conventional oxidative stress markers, this review also discusses the role of novel markers, focusing on their biological samples and detection techniques. Effective quantification of oxidative stress may enhance the understanding of this phenomenon, aiding in the maintenance of cellular integrity, prevention of age-associated diseases, and promotion of longevity.

Integrating Marma Sharira: Ayurveda’s Insights into Modern Traumatology

Marma Sharira, an integral concept in Ayurveda, represents vital points in the human body where the life force (Prana) is concentrated. Marma points are certain anatomical locations on the human body that are important for understanding trauma management and injury prevention in addition to preserving health. When these sites are traumatized there can be profound effects on the body and mind. Several clinical observations suggests that Marma therapy i.e. manipulation of Marma points not only accelerates the healing process but also enhances the body's innate capacity for recovery by harmonizing the flow of Prana (vital life force) facilitatingin pain management, stress reduction, musculoskeletal disorders, and enhancing overall vitality. By balancing the body's energy flow, it supports the immune system, accelerates healing processes, and improves quality of life. The paper also highlights the benefits of a multidisciplinary approach that combines traditional knowledge with modern medical procedures as reported in stroke management, and it explores how Marma Sharira's tenets might help with trauma treatment today.

Older Adult Education in the Context of Psychological Theories of Ageing

In gerontology, the essence of ageing is traditionally equated with decline and degradation, it is considered a purposeful process of loss of the body's adaptive capacity. Psychologists, in particular representatives of behaviorism, deny this position, instead they consider ageing to be an integral part of the general process of human development. Theories of ageing have progressed from focusing on individuals’ declines and losses in later phase of their life course to considering ageing as a continuous process of human development. Psychological theories of ageing are crucial to understanding older adults as learners ‒ their needs, abilities, motivation of learning and expectations from educational activity. They help us to develop comprehensive approaches to building an effective educational environment and improving the learning process of that age and social group aiming to adapt that environment to the needs of older adult learners. The article analyzes the main provisions of psychological theories of ageing, which substantiate the importance and even the necessity of involving older adults in educational activities, because firstly, mental activity contributes to the preservation and even development of a person’s intellectual capabilities until old age; secondly, in older people (compared to young people), changes in the ability to learn are insignificant and relate rather to the sphere of perception, attention, motivation, and the physiological state of the body; and thirdly, older people have a growing need for a sense of security, which has a significant impact on their quality of life and is largely realized through communication and learning activities. Based on the main tenets of psychological theories of ageing, in our research we consider older adults as a resource and human capital. We believe that the approach to the problem of ageing and old age from the resource perspective, which is based on the ideas of theories of activity and lifelong personality development, allows us to justify the need for education of older adults and is the basis of educational gerontology.

Schisandrol A Alleviates Allergic Asthma in Mice via Regulating the NF-κB/IκBα and Nrf2/HO-1 Signaling Pathways.

Schisandra chinensis (Turcz) Baill (S. chinensis) is the key traditional Chinese medicine for the treatment of asthma used by ancient and modern medical practitioners. However, the material basis and the main mechanism of its antiasthmatic effect remain unclear. Our preliminary results showed that schisandrol A (SCA), a representative monomer of Schisandra lignans, had the best relaxation effect on tracheal rings in isolated rats. In this research, a mouse asthma model was prepared by combining ovalbumin (OVA) with Al (OH)3 for exploring the antiasthmatic action and the underlying mechanism of SCA. The study results demonstrated that SCA improved the behavior of mice with asthma and pathological changes in their lung tissues and airways, decreased serum immunoglobulin E (IgE) and OVA-IgE levels, interleukin-4 (IL-4), IL-5, IL-13, and eotaxin contents, and leukocytes number in bronchoalveolar lavage fluid. SCA downregulated the gene expressions of keratinocyte-derived protein chemokines and ILs and reduced the expressions of phosphorylated IκB kinase α (p-IKKα) and p-nuclear factor kappa-B (NF-κB) proteins in lung tissues. In addition, it was found that SCA could significantly increase T-superoxide dismutase and catalase activities, decrease malondialdehyde content, and elevate p-IκBα, NF-E2-related-factor 2 (Nrf2), and heme oxygenase-1 (HO-1) protein expressions. In summary, SCA treatment resulted in a significant improvement in the allergic bronchial asthma in mice, and its mechanisms may involve the regulation of the NF-κB/IκBα pathway to reduce inflammatory response and the Nrf2/HO-1 pathway to improve the body's antioxidant capacity. These results suggest that SCA is a key component of S. chinensis in exerting antiasthmatic effects.

Effect of in ovo feeding with a multi-strain probiotic containing effective microorganisms and Zn-Gly chelate on the fatty acid profile, lipid profile, and malondialdehyde level in the serum and tissues of newly-hatched chickens

Modern poultry production strives to ensure the safety of food products by constantly improving the health parameters of birds. Multi-strain probiotics containing effective microorganisms and microelements, especially zinc in chelated form, currently play an important role in poultry feeding. We hypothesized that supplementation of chicken embryos with a multi-strain probiotic and glycine-zinc chelate may influence lipid metabolism in the serum and tissues of newly hatched chicks, leading to an increase in the body's antioxidant capacity. Therefore, the aim of the study was to assess the lipid profile, fatty acid profile and malondialdehyde (MDA) concentration in the serum and tissues of newly hatched chickens supplemented in ovo with a multi-strain probiotic and zinc glycine chelate. The experiment was conducted on 1,500 fertilized hatching eggs obtained from 36-week-old commercial broilers (Ross x Ross 308). A multi-strain probiotic and zinc glycine chelate (Zn-Gly) were administered on the 17th day of incubation. Samples of peripheral blood and tissues of the liver, small intestine (ileum), pectoral muscle, thigh muscle and yolk sac, collected on the day of hatch and at 7 days post-hatch, were used to analyse biochemical parameters and determine the malondialdehyde level and fatty acid profile. The results indicate that in ovo supplementation with a multi-strain probiotic and Zn-Gly chelate on the 17th day of incubation affects fat metabolism. Simultaneous administration of a multi-strain probiotic and Zn-Gly chelate did not increase the concentration of polyunsaturated fatty acids (PUFAs) in the muscles. In birds treated with Zn-Gly chelate, the PUFA concentration was increased in the muscle tissue in the period up to 7 days post-hatch, i.e. during the development of the chicks. Moreover, the analysis of the results confirmed that in ovo supplementation with a multi-strain probiotic and Zn-Gly chelate stimulates the synthesis of saturated fatty acids (SFAs), mainly stearic, palmitic and myristic acids, and improves the ratio of PUFAs to SFAs. The multi-strain probiotic and Zn-Gly chelate administered in ovo did not cause excessive MDA synthesis in the tissues, suggesting that these preparations reduce oxidative stress in the developing embryo and newly hatched chick.

Quantitative NMR Analysis of Marine Macroalgae for AGE Inhibition by Methylglyoxal Scavenging.

Reactive carbonyl species (RCS) induce a fundamental form of biological stress that has driven the evolution of diverse mechanisms for minimizing its impact on organismal health. The complications that accompany uncontrolled hyperglycemia exemplify the health implications when RCS stress exceeds the body's capacity to prevent the excessive formation of advanced glycation end-products. Presented here is a novel quantitative NMR (qNMR) technique for evaluating scavengers of the prominent sugar-derived carbonyl methylglyoxal (MGO). This tool was employed to screen the chemical diversity of marine macroalgae extracts, with a focus on species that have a history of consumption by the World's healthiest populations and are subject to global scale aquacultural production. Fucus vesiculosus demonstrated the highest capacity for inhibiting glycation and scavenging MGO. Additionally, the Chondrus cripsus, Gracilaria vermiculophyla, and Gracilaria tikvahiae extracts had a high capacity for scavenging MGO, representing the first report of this activity. This new qNMR methodology presented is highly applicable for screening extracts and compounds from diverse sources, and the results highlight the potential of macroalgae extracts to be employed as RCS and AGE targeting therapeutics and food additives.

Advancing Epigenetic and Antioxidant Strategies in Natural Therapeutics Against SARS-CoV-2: A Mini Review of Current Innovations and Future Directions

Abstract: This review explores the potential of natural products, particularly curcumin and gingerol, as immune regulators and anti-inflammatory agents in combating SARS-CoV-2 infections via epigenetic and antioxidant mechanisms. Oxidative stress induced by coronavirus infections can trigger severe immune responses, such as cytokine storms, often leading to therapy failure. This oxidative stress is exacerbated by depleted antioxidant defenses. The review examines how natural ingredients activate endogenous antioxidants through pathways like nuclear factor erythroid 2-related factor 2 (Nrf-2) activation, leading to gene expression changes without altering DNA structure. These changes enhance cellular defenses against oxidative stress and reduce inflammation, potentially mitigating the virus's effects. The methodology involved a literature review of scientific articles from databases such as Google Scholar, Elsevier, Science Direct, Scopus, and Wiley Online Library, focusing on publications from 2010 to 2023. Data were analyzed using deductive qualitative descriptive techniques, emphasizing the role of natural compounds in activating antioxidant responses to prevent or minimize cellular damage caused by COVID-19. The review underscores the significant role of diet and nutritional intake in supporting the body's antioxidant capacity by activating specific receptors that influence gene expression related to immune responses and cellular repair mechanisms. Flavonoids and anthocyanins are highlighted as key compounds in natural products with therapeutic potential against COVID-19. Overall, this research advocates for further exploration of natural products as viable options for preventing and treating COVID-19, suggesting that these compounds offer dual benefits of antiviral activity and immune modulation through epigenetic regulation and antioxidant support.

Review on Monoclonal Antibodies (mAbs) as a Therapeutic Approach for Type 1 Diabetes.

Monoclonal antibodies have been successfully utilized in a variety of animal models to treat auto-immune illnesses for a long time. Immune system responses will either be less active or more active depending on how the immune system is operating abnormally. Immune system hypoactivity reduces the body's capacity to fight off various invading pathogens, whereas immune system hyperactivity causes the body to attack and kill its own tissues and cells. For maximal patient compliance, we will concentrate on a variety of antibody therapies in this study to treat Type 1 diabetes (an autoimmune condition). T-cells are responsible for the auto-immune condition known as T1D, which causes irregularities in the function of β-cells in the pancreas. As a result, for the treatment and prevention of T1D, immunotherapies that selectively restore continuous beta cellspecific self-tolerance are needed. Utilizing monoclonal antibodies is one way to specifically target immune cell populations responsible for the auto-immune-driven disease (mAb). Numerous mAbs have demonstrated clinical safety and varied degrees of success in modulating autoimmunity, including T1D. A targeted cell population is exhausted by mAb treatments, regardless of antigenic specificity. One drawback of this treatment is the loss of obtained protective immunity. Immune effector cell function is regulated by nondepleting monoclonal antibodies (mAb). The antigenfocused new drug delivery system is made possible by the adaptability of mAbs. For the treatment of T1D and T-cell-mediated autoimmunity, different existing and potential mAb therapy methods are described in this article.

Teacher education students’ experiences navigating inherent requirements within their courses of study

ABSTRACT Inherent requirements define core competencies that all students must demonstrate to be accepted, progress, and successfully complete professionally accredited programmes such as teaching. This paper presents research that examines how students of teacher education navigate supposed abilities to teach through their courses of study, to inform the development of a statement of inherent requirements for a large school of education in an Australian university. Drawing on critical disability perspectives, we present results from a survey conducted with students enrolled in teacher education courses. This analysis demonstrates that inherent requirements have little affect for students whose bodily capacities align with preconceived notions of abilities to teach. Yet, students with disabilities will likely experience impose barriers to their success within teacher education because of perceived inherent requirements to practice, which is not easily addressed through disclosure and reasonable adjustments. The paper concludes with a discussion addressing how when seeking to expand their impact in support of inclusive local and global communities, universities must necessarily start by paying close attention to the ways that they frame competency in relation to equity. Here we draw from concerns raised by students in the present study, and critical disability theory, to support an institutional transposition from inherency to coherency, reframing how ability to teach can align with contemporary policy aspirations and inclusive practices. The paper is unique for drawing on student experiences to inform the development of knowledge in the field of teacher education along with critical disability perspectives with which to analyse them.

Role of nutraceuticals in viral infections as immunomodulators: A comprehensive review

AbstractNutraceuticals are dietary supplements produced from food sources that are intended to improve health through immune system modulation or by helping to prevent and treat a variety of ailments. Their anti‐inflammatory, immunomodulatory, and antioxidant qualities are well recognized. In certain instances, they even show direct microbiological efficacy against viral infections. Because of their special capacity, they may be able to help slow the spread and effects of very infectious illnesses, such as pandemics like COVID‐19. Nutraceuticals work well against viral infections because of a number of intricate processes. Reducing the harm that infections do to the immune system is one of the main effects. Nutraceuticals have the power to stimulate and activate the immune system, improving the body's capacity to identify and eliminate infections. Additionally, they are essential in reducing oxidative damage, which can result in serious consequences and is frequently intensified during viral infections. Nutraceuticals also strengthen immunity by promoting regulatory T cell differentiation and proliferation, which is crucial for preserving immune system homeostasis and limiting hyperinflammatory reactions. They control the production of proinflammatory cytokines, which helps to avoid cytokine storms during viral infections that may seriously harm tissue. This regulation lowers the danger of hyperinflammation and enhances overall results by supporting a balanced immune response. Through a number of biochemical mechanisms, nutraceuticals can strengthen the body's defenses against viral infections. They promote a more effective and efficient immune response by regulating immune cell activities, oxidative stress reduction, and antioxidant pathway activation. Furthermore, by interacting with different cellular signaling pathways, nutraceuticals can affect the synthesis and function of important immune components. This study clarifies the molecular processes behind the immunomodulatory effects of nutraceuticals, highlighting their crucial role in both treating and preventing viral infections.

Effects of higher dietary acid load: a narrative review with special emphasis in children.

Metabolic effects of high diet acid load (DAL) have been studied for years in adults, although only recently in children. Contemporary diets, especially those of Western societies, owe their acidogenic effect to high animal-origin protein content and low contribution of base-forming elements, such as fruits and vegetables. This imbalance, where dietary acid precursors exceed the body's buffering capacity, results in an acid-retaining state known by terms such as "eubicarbonatemic metabolic acidosis," "low-grade metabolic acidosis," "subclinical acidosis," or "acid stress". Its consequences have been linked to chronic systemic inflammation, contributing to various noncommunicable diseases traditionally considered more common in adulthood, but now have been recognized to originate at much earlier ages. In children, effects of high DAL are not limited to growth impairment caused by alterations of bone and muscle metabolism, but also represent a risk factor for conditions such as obesity, insulin resistance, diabetes, hypertension, urolithiasis, and chronic kidney disease (CKD). The possibility that high DAL may be a cause of chronic acid-retaining states in children with growth impairment should alert pediatricians and pediatric nephrologists, since its causes have been attributed traditionally to inborn errors of metabolism and renal pathologies such as CKD and renal tubular acidosis. The interplay between DAL, overall diet quality, and its cascading effects on children's health necessitates comprehensive nutritional assessments and interventions. This narrative review explores the clinical relevance of diet-induced acid retention in children and highlights the potential for prevention through dietary modifications, particularly by increasing fruit and vegetable intake alongside appropriate protein consumption.

Cardiovascular effects of long-duration space flight.

Early studies exploring the physiological effects of space travel have indicated the body's capacity for reversible adaptation. However, the impact of long-duration spaceflight, exceeding 6 months, presents more intricate challenges. Extended exposure to microgravity and radiation profoundly affects the CV system. Notable phenomena include fluid shifts toward the head and modified arterial pressure. These changes disrupt blood pressure regulation and elevate cardiac output. Additionally, the loss of venous compression leads to a reduction in central venous pressure. The displacement of fluid from the vascular system to the interstitium, driven by baroreceptor stimulation, results in a 10%-15% decline in plasma volume. Intriguingly, despite potential increases in cardiac workload, cardiac muscle atrophy and perplexing variations in hematocrit levels have been observed. The mechanism underlying atrophy appears to involve a shift in protein synthesis from the endoplasmic reticulum to the mitochondria via mortalin-mediated mechanisms. Instances of arrhythmias have been recurrently documented, although generally nonlethal, in both Russian and American space missions. Long-duration spaceflight has been associated with the prolongation of the QT interval, particularly in extended missions. Exposure of the heart to the proton and heavy ion radiation pervasive in deep space contributes to coronary artery degeneration, augmented aortic stiffness, and carotid intima thickening through collagen-mediated processes. Moreover, it accelerates the onset of atherosclerosis and triggers proinflammatory responses. Upon reentry, astronauts frequently experience orthostatic intolerance and altered sympathetic responses, which bear potential hazards in scenarios requiring rapid mobilization or evacuation. Consequently, careful monitoring of these cardiac risks is imperative for forthcoming missions. While early studies illuminate the adaptability of the body to space travel's challenges, the intricacies of long-duration missions and their effects on the CV system necessitate continued investigation and vigilance to ensure astronaut health and mission success.

Understanding the Multifaceted Process of Aging: Theories, Mechanisms, and Implications for Treatment

The aging process is a multifaceted biological phenomenon characterized by alterations at the molecular, cellular, and organ levels that culminate in a gradual, unavoidable, and unavoidable reduction in the body's capacity to react suitably to internal and/or external stimuli. Aging is a complex process that involves different mechanisms as The "Wear and Tear" Theory ,The Genetic Control Theory ,The Neuroendocrine Theory ,Waste Accumulation Theory ,Divisions Theory, Autoimmune Theory, Thymic-Stimulating Theory ,Mitochondrial Theory Mitochondria, Errors and Repairs Theory, Redundant DNA Theory Cross-Linkage Theory , Death Hormone Theory (DECO), Caloric Restriction Theory ,The Rate of Living Theory ,Gene Mutation Theory, Accumulated mutations Theory, Theory, Order to Disorder Theory, Disposable soma Theory, Antagonistic pleiotropy theory, The Telomerase Theory ,The free radical Theory. The two main categories of aging theories that explain cellular aging are structural damage and programmed theories. Different types of cells experience physiological stressors due to a range of circumstances. Notably, post-mitotic and mitotic cells have different capacities for proliferation and age differently in response to these pressures through different processes of cellular senescence and death, respectively. Over time, these aging cells build up and eventually cause old tissues to malfunction. The aim of this review is to throw light upon the effected of aging and who to treatment it.

Integrative Geriatric Oncology: A Review of Current Practices.

This article aims to offer a comprehensive review of optimal integrative medicine practices for geriatric oncology patients. Given the aging population and the global rise in cancer incidence, it is crucial to identify evidence-based modalities and employ an integrated approach to enhance cancer outcomes and quality of life in older adults. It has been predicted that 20.5% (6.9 million) of new cancer cases in 2050 will occur in adults over 80years old.1 The increasing focus on lifestyle factors in healthy aging has shed light on various overlooked areas of significance. Notably, anti-inflammatory diets and the promotion of a healthy gut microbiome have demonstrated significant impacts on overall health outcomes, bolstering the body's innate capacity to combat disease. This review delves into further evidence and extrapolation concerning integrative approaches and their influence on cancer outcomes and older adults quality of life. The complexity and unique nature of cancer in older adults requires a wide range of support from medical providers. Incorporating various integrative techniques as part of cancer treatment and side effect support can improve health outcomes and patient's quality of life. Familiarity with the lifestyle interventions and other topics explored in this review equips healthcare providers to offer tailored and holistic care to geriatric patients navigating cancer.
