Potentials of bone marrow cells-derived from naïve or diabetic mice in autoimmune type 1 diabetes: immunomodulatory, anti-inflammatory, anti hyperglycemic, and antioxidative.

The scarcity of transplanted human islet tissue and the requirement for immunosuppressive drugs to prevent the rejection of allogeneic grafts have hindered the treatment of autoimmune type 1 diabetes mellitus (T1DM) through islet transplantation. However, there is hope in adoptively transferred bone marrow cells (BMCs) therapy, which has emerged as a propitious pathway for forthcoming medications. BMCs have the potential to significantly impact both replacement and regenerative therapies for a range of disorders, including diabetes mellitus, and have demonstrated anti-diabetic effects. The main goal of this study is to evaluate the effectiveness of adoptively transferred bone marrow cells derived from either naïve mice (nBMCs) or diabetic mice (dBMCs) in treating a T1DM mice model. Male Swiss albino mice were starved for 16 h and then injected with streptozotocin (STZ) at a dose of 40 mg/kg body weight for 5 consecutive days to induce T1DM. After 14 days, the diabetic mice were distributed into four groups. The first group served as a diabetic control treated with sodium citrate buffer, while the other three groups were treated for two weeks, respectively, with insulin (subcutaneously at a dose of 8 U/kg/day), nBMCs (intravenously at a dose of 1 × 106 cells/mouse/once), and dBMCs (intravenously at a dose of 1 × 106 cells/mouse/once). It is worth noting that administering adoptively transferred nBMCs or adoptively transferred dBMCs to STZ-induced T1DM mice resulted in a significant amelioration in glycemic condition, accompanied by a considerable reduction in the level of blood glucose and glycosylated hemoglobin % (HbA1C %), ultimately restoring serum insulin levels to their initial state in control mice. Administering nBMCs or dBMCs to STZ-induced T1DM mice led to a remarkable decrease in levels of inflammatory cytokine markers in the serum, including interferon-γ (INF-γ), tumor necrosis factor- α (TNF-α), tumor growth factor-β (TGF-β), interleukin-1 β (L-1β), interlekin-4 (IL-4), interleukin-6 (IL-6), and interleukin-10 (IL-10). Additionally, STZ-induced T1DM mice, when treated with nBMCs or dBMCs, experienced a notable rise in total immunoglobulin (Ig) level. Furthermore, there was a significant reduction in the levels of islet cell autoantibodies (ICA) and insulin autoantibodies (IAA). Furthermore, the serum of STZ-induced T1DM mice showed a significant increase in Zinc transporter 8 antigen protein (ZnT8), islet antigen 2 protein (IA-2), and glutamic acid decarboxylase antigen protein (GAD) levels. Interestingly, the administration of nBMCs or dBMCs resulted in a heightened expression of IA-2 protein in STZ-induced T1DM mice treated with nBMCs or dBMCs. Furthermore, the level of malondialdehyde (MDA) was increased, while the levels of catalase (CAT) and superoxide dismutase (SOD) were decreased in non-treated STZ-induced T1DM mice. However, when nBMCs or dBMCs were administered to STZ-induced T1DM mice, it had a significant impact on reducing oxidative stress. This was accomplished by reducing the levels of MDA in the serum and enhancing the activities of enzymatic antioxidants like CAT and SOD. STZ-induced T1DM mice displayed a significant elevation in the levels of liver enzymes ALT and AST, as well as heightened levels of creatinine and urea. Considering the crucial roles of the liver and kidney in metabolism and excretion, this research further examined the effects of administering nBMCs or dBMCs to STZ-induced T1DM mice. Notably, the administration of these cells alleviated the observed effects. The present study suggests that utilizing adoptively transferred nBMCs or adoptively transferred dBMCs in the treatment of T1DM led to noteworthy decreases in blood glucose levels, possibly attributed to their capacity to enhance insulin secretion and improve the performance of pancreatic islets. Additionally, BMCs may exert their beneficial effects on the pancreatic islets of diabetic mice through their immunomodulatory, antioxidant, anti-inflammatory, and anti-oxidative stress properties.

Medicinal plants as a source of natural remedies in the management of diabetes

Diabetes is a severe chronic illness that has impacted thousands of individuals worldwide. It is caused by the body’s failure to produce insulin or insufficient production of insulin. While diabetes is not curable, it can be managed with injectable insulin, which decreases blood glucose levels. However, this treatment has several disadvantages that can affect a patient’s health, and it is often unaffordable for some individuals. Previous studies have suggested that phytochemicals can improve insulin sensitivity. Due to the presence of therapeutic phytochemicals in natural plants, medicinal plants emerge as potential candidates for treating diabetes. In addition, compared to conventional diabetes treatments, phytochemical treatment may be affordable for all diabetics and has fewer side effects. This review primarily focuses on the symptoms and treatment options for the four known types of diabetes: type 1 diabetes mellitus, type 2 diabetes mellitus, type 3c diabetes mellitus, and neonatal diabetes. The article reviews medicinal plants that have been used to treat diabetes effectively with minimum side effects, such as Momordica charantia L., Syzygium cumini (L.) Skeels, and Ocimum tenuiflorum L., among others. In addition, some newly approved drugs, such as tirzepatide, sergliflozin, saxagliptin, and liraglutide, recommended for treating patients suffering from various forms of diabetes, are discussed.

Chrysin-loaded PEGylated liposomes protect against alloxan-induced diabetic neuropathy in rats: the interplay between endoplasmic reticulum stress and autophagy

BackgroundDiabetic neuropathy (DN) is recognized as a significant complication arising from diabetes mellitus (DM). Pathogenesis of DN is accelerated by endoplasmic reticulum (ER) stress, which inhibits autophagy and contributes to disease progression. Autophagy is a highly conserved mechanism crucial in mitigating cell death induced by ER stress. Chrysin, a naturally occurring flavonoid, can be found abundantly in honey, propolis, and various plant extracts. Despite possessing advantageous attributes such as being an antioxidant, anti-allergic, anti-inflammatory, anti-fibrotic, and anticancer agent, chrysin exhibits limited bioavailability. The current study aimed to produce a more bioavailable form of chrysin and discover how administering chrysin could alter the neuropathy induced by Alloxan in male rats.MethodsChrysin was formulated using PEGylated liposomes to boost its bioavailability and formulation. Chrysin PEGylated liposomes (Chr-PLs) were characterized for particle size diameter, zeta potential, polydispersity index, transmission electron microscopy, and in vitro drug release. Rats were divided into four groups: control, Alloxan, metformin, and Chr-PLs. In order to determine Chr- PLs’ antidiabetic activity and, by extension, its capacity to ameliorate DN, several experiments were carried out. These included measuring acetylcholinesterase, fasting blood glucose, insulin, genes dependent on autophagy or stress in the endoplasmic reticulum, and histopathological analysis.ResultsAccording to the results, the prepared Chr-PLs exhibited an average particle size of approximately 134 nm. They displayed even distribution of particle sizes. The maximum entrapment efficiency of 90.48 ± 7.75% was achieved. Chr-PLs effectively decreased blood glucose levels by 67.7% and elevated serum acetylcholinesterase levels by 40% compared to diabetic rats. Additionally, Chr-PLs suppressed the expression of ER stress-related genes (ATF-6, CHOP, XBP-1, BiP, JNK, PI3K, Akt, and mTOR by 33%, 39.5%, 32.2%, 44.4%, 40.4%, 39.2%, 39%, and 35.9%, respectively). They also upregulated the miR-301a-5p expression levels by 513% and downregulated miR-301a-5p expression levels by 65%. They also boosted the expression of autophagic markers (AMPK, ULK1, Beclin 1, and LC3-II by 90.3%, 181%, 109%, and 78%, respectively) in the sciatic nerve. The histopathological analysis also showed that Chr-PLs inhibited sciatic nerve degeneration.ConclusionThe findings suggest that Chr-PLs may be helpful in the protection against DN via regulation of ER stress and autophagy.Graphical

Temuan Baru Ekstrak Kulit Nanas Sebagai Potensi Antidiabetes pada Tikus Putih (Rattus Norvegicus) Diinduksi Streptozotocin

Diabetes mellitus is chronic and metabolic disease which occurs because of the increase of blood glucose level or hyperglycemia caused the body which cannot produce or use insulin effectively. Hyperglycemia has a glucotoxic effect resulting in an increase in ROS (reactive oxygen species) thus inducing liver pathogenesis which promotes severe inflammatory and apoptotic responses, as indicated by an increase in the SGPT enzyme. The pineapple peel contains flavonoid. It is known of having a strong antioxidant activity. With the giving of pineapple peel extract, it is expected to decrease the blood glucose level. This research to find out the the effect of pineapple peel extract (Ananas comusus L. Merr) on decreasing blood glucose levels and SGPT levels in male white rats (Rattus norvegicus) induced by streptozotocin. This research is an experimental study with a research design of pretest and posttest control group design. The samples consisted of 18 rats divided into 6 groups consisted of: normal control, negative control, and positive control group given metformin, and pineapple peel extract with dose 200mg/KgBW, 300mg/KgBW and 500mg/KgBW for 28 days and the measurement of the rats blood glucose was conducted by blood glucose test meter at day 1, day 4 (after post inductionof STZ 45mg/KgBW given by intraperitoneal), and day 29. The analysis result of One Way ANOVA showed that pineapple peel extract with dose 200mg/KgBW, 300mg/KgBW, and 500mg/KgBW decrease the blood glucose level significant (p-value<0,05) with negative control group. There was no significant difference between 200mg/KgBW, 300mg/KgBW and 500mg/KgBW compared with positive control (p>0.05). There was an effect of pineapple peel extract administration on the SGPT levels of STZ-induced rats with a dose of 200mg/kg BW, 300mg/kg BW, 500mg/kg BW (p-value <0.05). The administration of 300mg/kg BW pineapple peel extract had the highest decrease in SGPT levels compared to other groups. Pineapple peel extract (Ananas comosus L. Merr) can reduce blood glucose leveland SGPT levels in rats induced by streptozotocin with the greatest reduction at dose 300mg/KgBW.

Ginseng extract improves pancreatic islet injury and promotes β-cell regeneration in T2DM mice.

Panax ginseng C. A. Mey. (Araliaceae; Ginseng Radix et Rhizoma), a traditional plant commonly utilized in Eastern Asia, has demonstrated efficacy in treating neuro-damaging diseases and diabetes mellitus. However, its precise roles and mechanism in alleviating type 2 diabetes mellitus (T2DM) need further study. The objective of this study is to explore the pharmacological effects of ginseng extract and elucidate its potential mechanisms in protecting islets and promoting β-cell regeneration. The T2DM mouse model was induced through streptozotocin combined with a high-fat diet. Two batches of mice were sacrificed on the 7th and 28th days following ginseng extract administration. Body weight, fasting blood glucose levels, and glucose tolerance were detected. Morphological changes in the pancreatic islets were examined via H & E staining. Levels of serum insulin, glucagon, GLP-1, and inflammatory factors were measured using ELISA. The ability of ginseng extract to promote pancreatic islet β-cell regeneration was evaluated through insulin & PCNA double immunofluorescence staining. Furthermore, the mechanism behind β-cells regeneration was explored through insulin & glucagon double immunofluorescence staining, accompanied by immunohistochemical staining and western blot analyses. The present research revealed that ginseng extract alleviates symptoms of T2DM in mice, including decreased blood glucose levels and improved glucose tolerance. Serum levels of insulin, GLP-1, and IL-10 increased following the administration of ginseng extract, while levels of glucagon, TNF-α, and IL-1β decreased. Ginseng extract preserved normal islet morphology, increased nascent β-cell population, and inhibited inflammatory infiltration within the islets, moreover, it decreased α-cell proportion while increasing β-cell proportion. Mechanistically, ginseng extract might inhibit ARX and MAFB expressions, increase MAFA level to aid in α-cell to β-cell transformation, and activate AKT-FOXM1/cyclin D2 to enhance β-cell proliferation. Our study suggests that ginseng extract may be a promising therapy in treating T2DM, especially in those with islet injury.

AMPK targets PDZD8 to trigger carbon source shift from glucose to glutamine.

The shift of carbon utilization from primarily glucose to other nutrients is a fundamental metabolic adaptation to cope with decreased blood glucose levels and the consequent decline in glucose oxidation. AMP-activated protein kinase (AMPK) plays crucial roles in this metabolic adaptation. However, the underlying mechanism is not fully understood. Here, we show that PDZ domain containing 8 (PDZD8), which we identify as a new substrate of AMPK activated in low glucose, is required for the low glucose-promoted glutaminolysis. AMPK phosphorylates PDZD8 at threonine 527 (T527) and promotes the interaction of PDZD8 with and activation of glutaminase 1 (GLS1), a rate-limiting enzyme of glutaminolysis. In vivo, the AMPK-PDZD8-GLS1 axis is required for the enhancement of glutaminolysis as tested in the skeletal muscle tissues, which occurs earlier than the increase in fatty acid utilization during fasting. The enhanced glutaminolysis is also observed in macrophages in low glucose or under acute lipopolysaccharide (LPS) treatment. Consistent with a requirement of heightened glutaminolysis, the PDZD8-T527A mutation dampens the secretion of pro-inflammatory cytokines in macrophages in mice treated with LPS. Together, we have revealed an AMPK-PDZD8-GLS1 axis that promotes glutaminolysis ahead of increased fatty acid utilization under glucose shortage.

Ketogenic Diet for Type I Diabetes Mellitus. Literature Review and Clinical Experience

To date, treating type I diabetes mellitus (T1D) is a difficult clinical task that is based, from the traditional point of view, exclusively on adjusting an insulin dose and monitoring a daily carbohydrate intake. Dietary changes are not considered a type of treatment in T1D patients yet, although this autoimmune disease is accompanied by disorders of carbohydrate metabolism. The article explores the international experience in the use of a low-carbohydrate diet and the features of disease development when putting patients into ketosis on a ketogenic diet. Article discusses the clinical experience obtained during T1D patient management, including ketogenic diet and mitochondrial support, at the clinic “PlanetaMed”. In addition, the article describes the case reports and case studies. According to the clinical experience of “PlanetaMed” specialists, the use of a ketogenic diet results in a decreasing blood glucose level in almost all cases. The average dose of injected insulin was 22.8 units before the ketogenic diet and 6,625 units during the ketogenic diet. The absolute decrease was 16.205 units, and the relative decrease was 70.9%. At the same time, the concentration level of glucose decreased by 39.2%. The decrease in blood glucose level and the injected insulin dose were connected (correlation coefficient: 0.76). Therefore, the studies have shown a significant positive impact of a ketogenic diet on the treatment of T1D patients.

Anti-Inflammatory, Wound Healing, and Anti-Diabetic Effects of Pure Active Compounds Present in the Ryudai Gold Variety of Curcuma longa.

Turmeric (Curcuma longa) contains curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC). Nevertheless, curcumin is the most researched active ingredient for its numerous pharmacological effects. We investigated the impact of these curcuminoids found in Ryudai gold, an approved cultivar of Curcuma longa, on wound healing, inflammation, and diabetes. Sub-planter injections of carrageenan induced acute paw inflammation in rats. The wound-healing ability of 1% curcuminoids was examined by making a 6 mm round wound on the shaved dorsum of the mice with a biopsy punch. A single intraperitoneal injection of streptozotocin (50 mg/kg) was used to induce diabetes in mice. Curcuminoids at a dose rate of 100 mg/kg body weight were used with feed and as a gastric gavage to treat diabetes and inflammation in experimental animals. Paw thickness was measured at 1, 3, and 6 h following carrageenan injection. After three hours, mean paw volume was 58% in carrageenan-injected mice, which was 35%, 37%, and 31% in the curcumin, DMC, and BDMC groups, respectively. Histopathology of the paw tissue demonstrated severe infiltration of inflammatory cells and thickening of the dermis, which were remarkably improved by the curcuminoids. The wound-healing abilities were significantly higher in the curcumin- (95.0%), DMC- (93.17%), and BDMC-treated (89.0%) groups, in comparison to that of the control (65.09%) group at day nine. There were no significant differences in wound-healing activity among the groups treated with 1% curcuminoids throughout the study. Streptozotocin-induced diabetes was characterized by an increased blood glucose (552.2 mg/dL) and decreased body weight (31.2 g), compared to that of the control rats (145.6 mg/dL and 46.8 g blood glucose and body weight, respectively). It also caused an increase in serum alanine aminotransferase (ALT; 44.2 U/L) and aspartate aminotransferase (AST; 55.8 U/L) compared to that of the control group (18.6 U/L and 20.1 U/L, respectively). Histopathological examination of the liver showed that diabetes caused hepatic cellular necrosis, congestion of the central vein, and parenchymatous degeneration. However, all three curcuminoids significantly decreased blood glucose levels, ALT, and AST and improved the histopathological score of the liver. These results evidenced that not only curcumin but also DMC and BDMC have potent anti-inflammatory, wound healing, and anti-diabetic efficacy, and the Ryudai gold variety of turmeric could be used as a functional food supplement.

Nutraceutical activities of Trigonella foenum-graecum and Nigella sativa seeds in the management of diabetes-induced in albino rats.

Diabetes causes elevated blood sugar levels, and it has been categorized as one of the most frequent causes of death worldwide. This work aimed to analyze and compare the nutraceutical and therapeutic efficacy of fenugreek seeds (FSs) (Trigonella foenum-graecum) and black cumin seeds (BCSs) (Nigella sativa) against streptozotocin-induced diabetes mellitus in albino rats. FS and BCSs were evaluated for proximate analysis, phytochemicals, and antioxidant activities. Male albino rats were used to evaluate the in vivo antidiabetic activities of these medicinal plants for 42 days. Blood samples were drawn at regular intervals of 1 week to analyze blood glucose, plasma insulin, and cholesterol levels and to determine the homeostatic model assessment of insulin resistance (HOMA IR) index. At the end of the trial, pancreas tissue was also collected for histological examination. Results of the proximate analysis showed the significant presence of moisture, ash, fat, protein, and fiber. Antioxidant parameters like 2,2-diphenyl-1-picrylhydrazyl, total phenolic content, and total flavonoid content were found to be significant. There was a significant (p<0.05) decrease in blood glucose level, serum cholesterol level, and insulin resistance in treatment groups T3-T5. Insulin and body weight results of treatment groups were significant (p<0.05) compared to streptozotocin-intoxicated animals. Histological examination revealed the nutraceutical impact of selected herbal plants due to enhancing impact on the size and the number of β-cells in the pancreas. Findings of current research work explore the antidiabetic capacity of selected nutraceutical and medicinal plants.

Secondary diabetes due to different etiologies: Four case reports

BACKGROUND As research on diabetes continues to advance, more complex classifications of this disease have emerged, revealing the existence of special types of diabetes, and many of these patients are prone to misdiagnosis and underdiagnosis, leading to treatment delays and increased health care costs. The purpose of this study was to identify four causes of secondary diabetes. CASE SUMMARY Secondary diabetes can be caused by various factors, some of which are often overlooked. These factors include genetic defects, autoimmune disorders, and diabetes induced by tumours. This paper describes four types of secondary diabetes caused by Williams–Beuren syndrome, Prader–Willi syndrome, pituitary adenoma, and IgG4-related diseases. These cases deviate significantly from the typical progression of the disease due to their low incidence and rarity, often leading to their neglect in clinical practice. In comparison to regular diabetes patients, the four individuals described here exhibited distinct characteristics. Standard hypoglycaemic treatments failed to effectively control the disease. Subsequently, a series of examinations and follow-up history confirmed the diagnosis and underlying cause of diabetes. Upon addressing the primary condition, such as excising a pituitary adenoma, providing glucocorticoid supplementation, and implementing symptomatic treatments, all patients experienced a considerable decrease in blood glucose levels, which were subsequently maintained within a stable range. Furthermore, other accompanying symptoms improved. CONCLUSION Rare diseases causing secondary diabetes are often not considered in the diagnosis of diabetes. Therefore, it is crucial to conduct genetic tests, antibody detection and other appropriate diagnostic measures when necessary to facilitate early diagnosis and intervention through proactive and efficient management of the underlying condition, ultimately improving patient outcomes.

The effect of ethanolic Acalypha Wilkesiana extract on blood sugar, sodium, potassium levels in alloxan-induced diabetic and salt-induced hypertensive Wistar rats

Diabetes Mellitus and hypertension often occur simultaneously. Hypertension affects approximately 70% of patients with diabetes, and the risk of cardiovascular disease in diabetic patients is three times higher than that in healthy individuals. The study was aimed at investigating the problem of diabetes and hypertension, and a possible remedy for it. Twenty-five (25) male wistar rats were assigned into five (5) groups of five (5) rats each. Group A served as negative control, and received water and feed only. Group B served as the positive control, and received alloxan160 mg/kg BW+ salt-loaded diet. Group C-E received alloxan 160 mg/kg BW+ salt-loaded diet + 100 mg/kg BW, 200 mg/kg BW, and 300 mg/kg BW of ethanolic acalypha wilkesiana (EAW) respectively. All administrations were given orally twice daily for 21 days. At the end of the treatment, blood samples were collected to estimate blood glucose, insulin, sodium, and potassium levels. Results are presented as mean±SEM, and were analysed using One-way ANOVA, statistical significance was considered at (P≤0.05). The results showed decrease in blood glucose levels and increase in insulin levels in groups C, D, and E compared to group B. There was also a decrease in sodium ion levels, and a concomitant increase in potassium ion levels in all wistar rat treatment groups when compared to group B. In summary, the results showed improved blood sugar, insulin, sodium, and potassium ion levels following EAW administration. It is therefore concluded that EAW administration was effective in improving diabetic and hypertensive complications in wistar rats.

Comparative transcriptome analysis provides a glance into the regulatory of insulin-like peptide 1 gene in the Pacific white shrimp Litopenaeus vannamei

Insulin-like peptides (ILPs) have been reported to exert significant and diverse regulatory effects through the insulin signaling pathway in invertebrates. However, there is a large research gap in the functional analysis of ILP genes in crustaceans. In this study, we combined RNA interference (RNAi) technology with transcriptome sequencing to investigate the regulatory effects of the ILP1 gene in the Pacific white shrimp Litopenaeus vannamei. After two weeks of continuous RNAi of LvILP1, the shrimp in the dsLvILP1 group exhibited reduced body length gain, weight gain, molting rate, and hemolymph glucose concentration compared to the control dsEGFP group, indicating that knockdown of LvILP1 slowed shrimp growth, molting, and metabolism. Comparative transcriptome analysis of three tissues revealed that knockdown of LvILP1 inhibited muscle growth and development by modulating the mTOR and MAPK signaling pathways, and prevented the renewal of epidermal tissue through the Hippo signaling pathway. Meanwhile, it also suppressed certain growth signals in the hepatopancreas, such as juvenile hormone (JH) synthesis and 20-hydroxyecdysteroid (20E) signal activation. Additionally, it promoted the conversion pathway of some sugars into amino acid metabolism instead of energy metabolism after glycolysis in the hepatopancreas. Interestingly, knockdown of LvILP1 also affected carbohydrate metabolism by regulating the intracellular and extracellular transport of glucose and trehalose, as well as regulating the expression levels of key metabolic genes in three shrimp tissues. This disruption led to a decrease in blood glucose levels and suppressed energy production, ultimately providing less energy for shrimp growth and molting. This study provides valuable insights into the underlying genetic mechanism through which ILP1 regulates glucose metabolism and growth in shrimp. It enhances our understanding of the structure and function of the insulin pathway in crustaceans and serves as an important reference for the identification of candidate genes in molecular genetic breeding of shrimp.

Characterization of Green Synthesized Nanoparticles with Anti-diabetic Properties. A Systematic Review.

Plants are used in medicine because they are low-cost, widely available, and have few side effects (compared to pharmacological treatment). Plants have phytocompounds with antidiabetic properties that can be delivered using nanoparticles (NPs). To describe the antidiabetic properties of green synthesized NPs (GSNPs) and their characterization methods. Three databases were searched using the terms "type 2 diabetes mellitus," "antidiabetic effects," "phytochemicals," "plants," and "nanoparticles." Studies describing the antidiabetic effects (in vitro or animal models) of NPs synthesized by plant extracts and characterizing them through UV-Vis spectroscopy, FTIR, XRD, SEM, TEM, and DLS were included. 16 studies were included. In vitro studies reported enzyme inhibition values between 11% (H. polyrhizus) and 100% (A. concinna) for alfa-amylase and between 41.1% (M. zapota) and 100% (A. concinna) for alfa-glucosidase. Animal studies with Wistar Albino rats having diabetes (induced by alloxan or streptozotocin) reported improved blood glucose, triglycerides, total cholesterol, LDL, and HDL after treatment with GSNPs. Regarding characterization, NP sizes were measured with DLS (25-181.5 nm), SEM (52.1-91 nm), and TEM (8.7-40.6 nm). The surface charge was analyzed with zeta potential (-30.7 to -2.9 mV). UV-Vis spectroscopy was employed to confirm the formations of AgNPs (360-460 nm), AuNPs (524-540 nm), and ZnONPs (300-400 nm), and FTIR was used to identify plant extract functional groups. GSNP characterization (shape, size, zeta potential, and others) is essential to know the viability and stability, which are important to achieve health benefits for biomedical applications. Studies reported good enzyme inhibition percentages in in vitro studies, decreasing blood glucose levels and improving lipid profiles in animal models with diabetes. However, these studies had limitations in the methodology and potential risk of bias, so results need careful interpretation.

Diabetes is a health burden in various countries, one of these countries, is also Indonesia. Dragon fruit peel is an alternative diabetes therapy that has been widely studied. Therefore, this study aimed to investigate an antidiabetic effect of dragon fruit peel methanol extract on alloxan-induced diabetic male Wistar rats. This experimental study used twenty-five male Wistar rats induced by alloxan injection. After 48 hours, all rats were grouped into five different groups, including control (0.5% SCMC), standard (Metformin), Dragon Fruit Peel Methanol Extract-1 (500 mg/kg BW), 2 (750 mg/kg BW), and 3 (1,000 mg/kg BW). These treatments were given for two weeks. After that, all rats were dissected to obtain the pancreas. The results showed that dragon fruit peel methanol extract significantly decreased blood glucose levels after the 7th and 14th days (P value &lt;0.05). In addition, pancreatic histology showed a decrease in the extract dose followed by a smaller size of the pancreatic Langerhans islet. The lowest dose of the extract showed a similar size of pancreatic Langerhans islet to the control group with an atrophic pancreatic Langerhans islet. Therefore, it can be concluded that dragon fruit peel extract can significantly decrease blood glucose levels and improve the structure of pancreatic Langerhans islet at higher doses.

Conclusion: Nanoparticle containing kenikir leaf ethanol extract successfully prepared into nanoparticles and the potential to increase antidiabetic activity.

Bioactive Compounds of Rosa canina L. and Their Effect on Tumor Necrosis Factor-α and Interleukin-1β Activity in Diabetes-Induced Rats

The ethnopharmacological significance of Rosa canina, or dog rose, transcends diverse cultures, with traditional applications in treating various diseases. This study investigates the potential pharmacological application of Rosa canina for diabetes treatment, aiming to assess its antidiabetic properties through in vitro, in vivo, and in silico analyses targeting pro-cytokines. Biochemical profiling utilizing HPLC, and phenolic content analyses were conducted to reveal the antioxidant properties of Rosa canina. In diabetic rats, root extracts influenced the expression of TNF-α and IL-1β, with an exploration of DNA-binding and protective activities. DPPH scavenging and iron chelating activities were measured, identifying significant IC50 values. The chromatographic analysis identified various compounds, with Kaempferol 3-O-glucoside and Rutin exhibiting high inhibitory activity against TNF-alpha. In silico analyses highlighted inhibitory activities by molecular docking against TNF-α and IL-1β (PDB IDs 2AZ5 and 9ILB, respectively) and their drug potential based on ADMET properties. The obtained results have demonstrated a significant decrease in blood glucose levels in mice through the reduction of TNF-α and IL-1β mediated diabetic processes, facilitated by the Rosa canina extract. In conclusion, this study exploring the effects of Rosa canina extracts on diabetic rats have provided valuable insights into its potential therapeutic benefits. The observed reductions in blood glucose levels, improvements in lipid profiles, and modulation of antioxidant activity highlight its promising role in managing diabetes-related complications. Further research is warranted to elucidate the underlying mechanisms and optimize the dosage regimens for harnessing the full therapeutic potential of Rosa canina extracts in diabetes management.

Assessment of Serum Insulin and VASPIN Levels Among Type 2 Diabetes Mellitus Patients with or Without Obesity: A Cross-sectional Analytical Study

ABSTRACT Introduction: A collection of diverse conditions together referred to as diabetes mellitus frequently manifest as periods of hyperglycemia and glucose intolerance, which can be caused by insufficient insulin, improper insulin action, or both. A medical condition known as obesity is the accumulation of excess body fat to the point that it may be harmful to one’s health. It has been determined that the adipokine vaspin (visceral adipose tissue-derived serpin A12) belongs to the family of serine protease inhibitors. Insulin, a polypeptide hormone, is released by the pancreatic beta cells. This hormone is both anti-catabolic and anabolic. Insulin decreases blood glucose levels by preventing its synthesis and encouraging its storage and use. Methodology: In total, 125 male and female participants of various ages participated in the current study. They included 25 healthy controls, 50 non-obese and 50 obese non–insulin-dependent diabetes mellitus patients, who visited the MDM Hospital’s outpatient clinic in Jodhpur, Rajasthan. Commercially available reagents and kits were utilized for the analysis of serum insulin and vaspin samples. Standard statistical tools were utilized to evaluate the parameters. Results and Discussion: When results were compared with healthy participants and non-obese NIDDM subjects, obese NIDDM subjects showed statistically significant higher fasting serum insulin and serum vaspin levels (P &lt; 0.0001). Conclusion: Our study’s conclusions demonstrated a strong correlation between blood insulin and vaspin levels and diabetes and obesity. Vaspin has a positive impact on insulin resistance, obesity, type 2 diabetes, and metabolic syndrome. It also enhances glucose tolerance and insulin sensitivity, reducing diabetes complications. This novel biomarker has the potential to enhance diabetes mellitus outcomes by facilitating prompt diagnosis, improved management, and reduction of complications.

Efek Pemberian Ekstrak Daun Gelagah (Saccharum spontaneum L.) terhadap Diabetes Induksi Aloksan pada Tikus Putih (Rattus Norvegicus)

Saccharum spontaneum L. (Family: Poaceae) is a tall perennial grass with deep roots and rhizomes, capable of growing up to 3-4 meters in height, and is commonly found along water bodies or roadsides. This plant is widely distributed throughout the tropical regions of Asia, Africa, America, and Australia. Saccharum spontaneum L. is a tall, erect, perennial grass with feathery inflorescences, often growing in swampy areas. Its leaves and stems contain lignin, carbohydrates, proteins, and amino acids, while its roots and lower stems contain starch and polyphenolic compounds. This study aims to evaluate the effect of Saccharum spontaneum L. leaves extract on blood glucose levels in male white rats (Rattus norvegicus) induced with alloxan. The leaves extract was obtained through maceration using 96% ethanol solvent. Phytochemical screening results indicated that the leaves of Saccharum spontaneum L. contain alkaloids, flavonoids, saponins, tannins, and steroids/triterpenoids. The antidiabetic test was conducted using male Wistar rats. In this study, the Saccharum spontaneum L. leaves extract was administered in three different doses: group 4 received a dose of 100 mg/KgBW, group 5 received a dose of 200 mg/KgBW, and group 6 received a dose of 400 mg/KgBW. Additionally, there were control groups consisting of group 1 (normal), group 2 (negative control), and group 3 (positive control) which were given the drug glibenclamide 5 mg/60 kg. All doses were administered orally. Diabetes induction in the rats was performed using alloxan monohydrate at a dose of 100 mg/KgBW administered intraperitoneally. The results of the study showed that the greatest reduction in blood glucose levels occurred in group 6 with a dose of 400 mg/KgBW, which decreased blood glucose levels by 71.78% at the 180th minute. Group 5 showed a reduction of 55.80% and group 4 showed a reduction of 51.91% at the 180th minute. Group 3, which was given glibenclamide, showed a reduction in blood glucose levels of 71.14% at the 180th minute. These results indicate that the highest dose of Saccharum spontaneum L. leaves extract (400 mg/KgBW) had the most significant effect in lowering blood glucose levels in male Wistar rats induced with alloxan monohydrate

Methanolic extract of Merremia emarginata (Burm. f.) Hallier f. attenuates renal damage in streptozotocin-induced diabetic nephropathy in rats

IntroductionMerremia emarginata (syn: Ipomoea reniformis) is used by the traditional healers of the Tirunelveli district of Tamil Nadu and Nelliampathy hills of Kerala for the treatment of diabetes. It contains important phytoconstituents like scopoletin, quercetin, and kaempferol and is reported to have pharmacological activities like antidiabetic antioxidant, antihyperlipidemic, ACE inhibitory, and hypotensive. Diabetic kidney disease is a common microvascular complication seen in patients with long-term diabetes. This study aimed to investigate the efficacy of Merremia emarginata in attenuating diabetic kidney disease. Materials and methodsDiabetes was induced by a single i.p. injection of 55 mg/kg streptozotocin (STZ). The animals were divided into seven groups with six rats in the control group and seven each in the STZ, STZ + Standard drug Ramipril (STD), STZ + Low dose (LD) methanolic extract of Merremia emarginata (MEME), STZ + High dose (HD) MEME, STZ + STD + LD, and STZ + STD + HD groups. The renal function was assessed by estimating various parameters viz, blood glucose, serum and urine creatinine, urine albumin, blood urea nitrogen (BUN), glycosylated haemoglobin (HbA1c) levels, oxidative stress, and kidney hypertrophy. ResultsTreatment with Ramipril and HD MEME showed a decrease in blood glucose levels, urine albumin, a decrease in serum creatinine, an increase in urine creatinine, a decrease in BUN, HbA1c, kidney hypertrophy, and oxidative stress. The combination treatment of Ramipril and HD MEME showed a synergistic effect. ConclusionThe study revealed that MEME attenuates diabetic nephropathy and has the potential to be used in diabetic nephropathy either alone or as an adjuvant.
