Abstract

One of the most serious side effects of diabetes is diabetic foot ulceration (DFU). It is a severe and extremely morbid illness that has been linked to higher mortality on its own. The development of effective wound therapeutics in the future may be influenced by our current and developing understanding of wound pathophysiology. By reestablishing cellular functioning, small extracellular vesicles (sEVs), a crucial medium for intercellular communications, exhibit encouraging therapeutic potential in the treatment of DFU. Mesenchymal stem cell (MSC) derived exosomes and engineered extracellular vesicles (EVs) have the potential to aid in the healing of wounds. Along with encouraging the growth and stimulation of endothelial cells, keratinocytes, and fibroblasts, they also have immunomodulatory and anti-inflammatory properties. They help prevent damaged cells from dying, revitalize senescent cells, and boost angiogenesis. MSC-EVs can be a safe, effective and ethical therapy for DFU by increasing M2 macrophages polarization, improving the proliferation, reducing scar, and improving angiogenesis.KEYWORDS: mesenchymal stem cell, extracellular vesicle, diabetic wound, wound healing

Abstract

Diabetes mellitus (DM) is a chronic endocrine and metabolic disease indicated by the presence of hyperglycemia. It has been known that hyperglycemia and oxidative stress are the main culprit of all DM complications, including macrovascular complications. As a byproduct of lipid, protein, and carbohydrate metabolism, methylglyoxal (MGO) is a highly reactive substance which plays a positive signaling role in helping cells regain redox balance under oxidative stress circumstances. DM-related problems lead to an excess of mitochondrial superoxide in the heart and big and small vascular endothelial cells. Elevated intracellular reactive oxygen species induce impaired angiogenesis in reaction to ischemia, trigger several proinflammatory pathways, and result in enduring epigenetic modifications that propel the continuous expression of proinflammatory genes even after glucose levels return to normal. Over time, the significance of the extremely quick advanced glycation end-products (AGE) production caused by the extremely reactive MGO has been clarified. It is now evident that MGO causes vascular tissue to react maladaptively. Glyoxalase 1 (GLO1) is the primary enzyme in an organism's enzymatic glyoxalase defense mechanism, which converts MGO to D-lactate in order to counteract the harmful effects of MGO. Understanding the role of the MGO–GLO1 pathway in the etiology of vascular disease in diabetes has advanced significantly. Therefore, it can be summarized that vascular damage are linked to diabetes. The AGE precursor MGO are important in determining the connection between diabetes and vascular damage. MGO and AGEs play a role in several phases of the development of diabetes complications. MGO and AGEs may be useful therapeutic targets for diabetes's macrovascular problems.KEYWORDS: hyperglycemia, AGE, methylglyoxal, glyoxalase, D-lactate, gluthatione, oxidative stress

Abstract

BACKGROUND: World Health Organization has reported four million people die every year due to obesity comorbidity, and the prevalence of obesity is keep increasing, especially after COVID-19. Obesity has been defined as a chronic disease involving adipose tissue dysfunction which leads to metabolic diseases and psychosocial consequences. The review article will highlight some recent researches regarding the new conceptual framework that integrates both metabolic drives, as well as to summarize the numerous discussions about the current understanding of hypothalamic control of food intake and energy homeostasis.CONTENT: Obesity apparently is not simply regulated only by food and exercise. Hypothalamus takes part in controlling energy intake and expenditure via appetite regulation. Hedonic control in cortical and subcortical brain areas process cognitive, reward, information, and executive function. Managing metabolic adaptation, browning the white adipose tissue, and preserving lean mass can be another strategy to safely manage obesity.SUMMARY: Obesity need to be managed in a multimodal strategy including neurophysiology and physiology approach, together with environment support. Thus, a weight regain can be prevented. Commitment from both scientific and regulation point of view can shed a light to eradicate obesity.KEYWORDS: adipocyte, appetite, nutrition, obesity, physical activity, reward, satiety

Abstract

BACKGROUND: Fibronectin type III domain-containing protein 5 (FNDC5), or also known as irisin, has been identified for two decades but almost completely disregarded for 10 years. It is present in skeletal muscle, heart, and brain, and in reaction to exercise can transform white adipose tissue into brown. Since then, irisin has gained a lot of attention for its potencies in treating metabolic disorders. In this review article, the potential future of irisin especially on metabolism and aging process will be discussed.CONTENT: Sedentary lifestyle is acknowledged as risk factor for type 2 diabetes mellitus, obesity, immune system issues, asthma, and neurological or heart illness. Irisin is secreted by muscle cells when exercising, produced after the proteolytic cleavage of FNDC5 protein. Irisin has positive impacts on maintaining physiological balance including reducing inflammation, keeping the bone homeostasis, as well as influencing metabolic processes and the neurological system function. Due to these many and advantageous characteristics, irisin could be a possible choice for preventing and managing disorders associated with modern society, and finding the agents to increase irisin can be beneficial.SUMMARY: Irisin offers a fresh potential basis for kinesitherapy and shows promise as a therapeutic target due to its various biological activities. Irisin pathway can be activated through dietary changes, the use of natural substances and drugs and can interact with this signalling pathway which involved peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) and uncoupling protein mRNA 1 (UCP1) to resolve obesity and its metabolic comorbidities.KEYWORDS: irisin, FNDC5, exercise, inflammation, obesity, nervous system

Abstract

Extracellular vesicles (EVs) are membrane structures that enclose proteins, lipids, RNAs, metabolites, growth factors, and cytokines. EVs derived from mesenchymal stem cells (MSCs) can either stimulate or inhibit tumor growth in various malignancies through paracrine signaling. Tumor-associated MSCs (TA-MSCs), often described as "wounds that never heal," actively participate in the development, propagation, and metastasis of tumors, impacting the immunological state of the tumor microenvironment. For instance, TA-MSCs can alter immune cell recruitment and cytokine production, leading to a pro-tumorigenic environment. Consequently, both the tumor and its microenvironment undergo functional alterations, the cargo of exosomes is modified, and an abnormal tumor-associated MSC phenotype is acquired. MSC-EVs contain exosome microRNA with both tumor-inhibitory and tumor-supportive effects. For example, MSC-EVs have been shown to deliver tumor-suppressive microRNAs that inhibit cancer cell proliferation and induce apoptosis. This review outlines the criteria for the modification, isolation, and characterization of exosomes, as well as their application in cancer, providing insights for clinical use. By understanding these mechanisms, we can better harness MSC-EVs for therapeutic purposes.Keywords: mesenchymal stem cell, extracellular vesicle, exosome, cancer therapy, drug delivery

Abstract

BACKGROUND: Age contributes to body composition alteration, rises a common disorder in elderly known as sarcopenic obesity (SO), which is characterized by the combination of obesity (excess fat mass) and sarcopenia (reduced skeletal muscle mass) clinical form and function.CONTENT: The primary cause of SO is insulin resistance. Glucose transporter 4 (GLUT4) dysfunction results in impaired fatty acids oxidation. Decreased muscle mass results in lower mitochondria number and volume. Both will increase oxidative stress. Together with altered myokines in SO, oxidative stress was promoted and lead to higher M1 macrophages and failure in autophagy. The pro-inflammatory condition and dysbiosis links SO to a variety of cardiometabolic conditions, including non-alcoholic fatty liver disease, type 2 diabetes, and cardiovascular disease. The mortality, comorbidities, cardiometabolic diseases, and disability or impairment of SO is higher compare to obesity or sarcopenia alone. Some treatments have been developed for SO including adequate dietary intake, vitamin D and antioxidant supplementation, and exercises.SUMMARY: SO is more prevalent among the elderly and has a significant negative impact on their quality of life. Therefore, maintaining muscle mass and strength as well as preventing obesity should be the key goals of initiatives to support healthy aging.KEYWORDS: aging, body composition, obesity, sarcopenia, skeletal muscle, metabolic syndrome

Abstract

Brazilian spinach is a highly nutritious leafy vegetable containing vitamins, minerals, and dietary fiber. This study assesses the impact of pruning intensities and non-nutrient ameliorants on Brazilian spinach growth in a floating cultivation system. The research follows a factorial randomized block design, with pruning intensity as the first factor and non-nutrient ameliorant as the second factor. Pruning intensity was categorized as light, moderate, and heavy, while the non-nutrient ameliorant included control, fine sand, rice-husk biochar, and fine sand + rice-husk biochar. The results show that moderate and heavy pruning effectively improved the response to NPK fertilization. Moderate pruning is proven to trigger the canopy area, especially starting 2 to 4 weeks after pruning. The Brazilian spinach canopy area demonstrated exponential growth and positively correlated with canopy diameter. The photosynthesis distribution in branch and shoot on moderate pruning was higher than heavy pruning, as indicated by dry weight. Moderate pruning produced a higher marketable yield than other pruning intensities. Regarding non-nutrient ameliorants, there are similarities in SPAD value, canopy area, index, dry weight, and yield. Therefore, moderate pruning is an effective practice to improve the growth and yield of Brazilian spinach, while the selected non-nutrient ameliorants have no impact.

Abstract

The location of the office of PT PLN (Persero) UPP Kitring Nusra 2 is in Ende Regency approximately 200 kilometers from the project locations currently managed. This makes the process of supervision and coordination with relevant stakeholders difficult. Throughout 2022 until now, work supervision, certification, land, ROW, and licensing activities have dominated the West Flores area. Therefore, for effective and efficient implementation of the main duties and functions, consideration of moving the office location to Labuan Bajo City needs to be done. This study aims to evaluate the feasibility of moving the office. The analysis method was carried out using factor rating and SWOT methods. The results of the comparison of 2 locations using the factor rating method show that the potential office location is in Labuan Bajo with a value of 95.81 and the existing location of Ende City is worth 84.19. Meanwhile, based on SWOT analysis, it was obtained that the location of the office in Labuan Bajo was in quadrant 1, so it can be concluded that the transfer is said to be feasible.
