Abstract
Background: Diabetes is a metabolic disorder characterized by high plasma glucose levels. In this disease, increased production of reactive oxygen species (ROS) results in DNA damage and multiple complications. L-carnitine (LC) has shown a potent antioxidant activity that may reduce oxidative stress. Objectives: This study aims at assaying the effect of LC on DNA damage in streptozotocin-induced diabetic rats and evaluating the changes in antioxidant markers and liver function enzymes after the administration of LC . Methods: In the present study, for induction of diabetes, we injected a single dose of streptozotocin (65 mg/kg) by the intraperitoneal route, and diabetic rats were treated with LC 200, 300, and 400 mg/kg daily for 3 weeks. We detected the DNA damage at 7, 14, and 21 days after induction diabetes by the comet assay method. The blood glucose level, plasma alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were tested. Also, we measured the activity levels of superoxide dismutase (SOD) and intracellular glutathione (GSH). Results: The results of this study demonstrated the increasing amount of DNA damage with the amount and duration of hyperglycemia. L-carnitine treatment significantly decreased the parameters of genotoxicity such as % DNA in the tail, tail length, and tail moment over time. Moreover, the treatment of diabetic rats with LC 300 and 400 mg/kg/day after 21 days led to a remarkable decrease in blood glucose than diabetic rats. Also, we observed that LC can ameliorate enzyme liver function and reduce oxidative stress via enhancement of GSH and SOD levels. Conclusions: The results of this study indicated the protective effect of LC against DNA damage and oxidative stress in diabetic rats.

Abstract
Various studies, especially in recent years, have shown that quercetin has beneficial therapeutic effects in various human diseases, including diabetes. Quercetin has significant anti-diabetic effects and may be helpful in lowering blood sugar and increasing insulin sensitivity. Quercetin appears to affect many factors and signaling pathways involved in insulin resistance and the pathogenesis of type 2 of diabetes. TNFα, NFKB, AMPK, AKT, and NRF2 are among the factors that are affected by quercetin. In addition, quercetin can be effective in preventing and ameliorating the diabetic complications, including diabetic nephropathy, cardiovascular complications, neuropathy, delayed wound healing, and retinopathy, and affects the key mechanisms involved in the pathogenesis of these complications. These positive effects of quercetin may be related to its anti-inflammatory and anti-oxidant properties. In this article, after a brief review of the pathogenesis of insulin resistance and type 2 diabetes, we will review the latest findings on the anti-diabetic effects of quercetin with a molecular perspective. Then we will review the effects of quercetin on the key mechanisms of pathogenesis of diabetes complications including nephropathy, cardiovascular complications, neuropathy, delayed wound healing, and retinopathy. Finally, clinical trials investigating the effect of quercetin on diabetes and diabetes complications will be reviewed.

Abstract
Background The aim of this study was to investigate the relationship of dietary total antioxidant capacity (DTAC) with sarcopenia and metabolic biomarkers in people with type 2 diabetes in the Kurdish race. Methods In this cross‐sectional study, data of 189 type 2 diabetic patients (35–65 years old) from RaNCD cohort study were evaluated. DTAC, fasting blood sugar, lipid profile, body composition, muscle strength, and sarcopenia were assessed. t and χ2 tests to compare the variables between sarcopenic and non‐sarcopenic patients and one‐way analysis of variance to compare the variables in DTAC tertiles were used. The relationship between DTAC and different variables was evaluated using multiple logistic regression model. Results The mean age and body mass index were 49.7 ± 8.7 years and 27.1 ± 3.9 kg/m2. Body mass index, waist circumference, and hip circumference were significantly different between diabetic patients with and without sarcopenia (p < 0.05). In crude (p = 0.010) and adjusted (p = 0.035) models, there was a significant relationship between DTAC and fasting blood sugar. Also, the relationship between DTAC with waist (p = 0.019) and hip (β = −4.25, p = 0.026) circumference was significant. Sarcopenia was significantly lower in the third tertile in comparison with the first tertile of DTAC (p = 0.016). Conclusion Diet with higher DTAC can be associated with lower fasting blood sugar, abdominal obesity and sarcopenia in type 2 diabetic patients. However, further studies are required to confirm these relationships.

Abstract
INTRODUCTION Dyslipidemia is a hallmark of T2DM, and as such, analyses of lipid metabolic profiles in affected patients have the potential to permit the development of an integrated lipid metabolite-based biomarker model that can facilitate early patient diagnosis and treatment. METHODS Untargeted and targeted lipidomics approaches were used to analyze serum samples from newly diagnosed 93 Chinese participants in discovery cohort and 440 in validation cohort via UHPLC-MS and UHPLC-MS/MS first. The acid sphingomyelinase protein expression was analyzed by Western blot. RESULTS AND DISCUSSION Through these analyses, we developed a novel integrated biomarker signature composed of LPC 22:6, PC(16:0/20:4), PE(22:6/16:0), Cer(d18:1/24:0)/SM(d18:1/19:0), Cer(d18:1/24:0)/SM(d18:0/16:0), TG(18:1/18:2/18:2), TG(16:0/16:0/20:3), and TG(18:0/16:0/18:2). The area under the curve (AUC) values for this integrated biomarker signature for prediabetes and T2DM patients were 0.841 (cutoff: 0.565) and 0.894 (cutoff: 0.633), respectively. Furthermore, theresults of western blot analysis of frozen adipose tissue from 3 week (prediabetes) and 12 week (T2DM) Goto-Kakizaki (GK) rats also confirmed that acid sphingomyelinase is responsible for significant disruptions in ceramide and sphingomyelin homeostasis. Network analyses of the biomarkers associated with this biosignature suggested that the most profoundly affected lipid metabolism pathways in the context of diabetes include de novo ceramide synthesis, sphingomyelin metabolism, and additional pathways associated with phosphatidylcholine synthesis. Together, these results offer new biological insights regarding the role of serum lipids in the context of insidious T2DM development, and may offer new avenues for future diagnostic and/or therapeutic research.

Abstract
Abstract
Carnitine (β-hydroxy-γ-trimethyl amino butyrate) is, a vitamin-like substance carrying long-chain fatty acids into the mitochondrial matrix. Due to its effect in energy metabolism, carnitine plays an important role in controlling diabetes and its complications. Studies on this topic have often focused on carnitine supplementation. This study was planned to investigate the relationship between serum carnitine level, glucose regulation and body fat in diabetic patients. A total of 64 people between the ages of 30-5, 32 patients with type 2 diabetes and 32 healthy subjects, were included in the study. Individual lipid profiles, glucose, insulin and serum carnitine levels were analyzed, anthropometric measurements were taken and 24-hour recall food consumption was recorded. As a result, blood glucose, insulin, triglyceride, VLDL-C, HDL-C and HOMA-IR were found to be higher in diabetic individuals than healthy group (p<0,05). Serum carnitine levels were found to be significantly lower in diabetic male (50,6±20,83 nmol/mL) than in healthy male (59,5±17,25 nmol/mL)(p<0,05). This difference was not statistically significant among female (p>0,05). It has been observed that intake of energy and macronutrients of diabetic individuals is generally lower than that of healthy individuals. Serum carnitine level was positively associated with polyunsaturated fatty acids and omega-6 fatty acid intake in male in the healthy group showed a negative correlation with fiber intake in female in the healthy group (p<0,05). There were negative correlations between serum carnitine level with body weight, body mass index and body fat mass in female in the healthy group (p<0,05). Individuals with diabetes are predisposed to dyslipidemia and insulin resistance. As a result; food consumption, and body fat affect individuals’ serum carnitine levels in type-2 diabetes. Since there is not enough study evaluating the relationship between anthropometric measurements of individuals and serum carnitine levels, it is thought that this result will guide future studies.

Abstract
Background Organophosphorus (OP) compounds have been widely available for decades in agriculture for crop protection and as cheap pest controllers, which increases the rate of exposure and poisoning cases. Using serum cholinesterase as prognostic markers for the acute OP toxicity is controversial; therefore, we aim to find out prognostic biomarkers that best correlate with mortality and outcomes of patients with acute OP toxicity. Levels of serum oxidative stress biomarkers (malondialdehyde (MDA) and total antioxidant capacity (TAC)) and activity of the apoptotic biomarkers (caspase 3 and caspase 9) and pseudo-cholinesterase (p.ChE) were performed. Also, we evaluated the apoptotic capacity through determining the genotoxic effects and chromosomal abnormalities among OP intoxicated patients. Results We found the activity of caspases and serum MDA and TAC were significantly increased after OP poisoning and decreased after the appropriate atropine and oxime treatment course. The ROC curve suggested caspases as mortality and outcome predictive markers for acute OP poisoning patients. However, OP poisoning cases before treatment showed significant DNA damage, and they did not show any chromosomal aberration. Conclusion The mentioned results strongly suggest apoptotic-related markers (caspase 3, caspase 9) as prognostic markers for evaluation of the treatment, outcomes, and mortality rate in the acute OP toxicity patients.

Abstract
Silkworms have been reported to promote the growth and production of the stromata of C. militaris (L.) Link as a parasite insect medium and may improve its metabolites. The effects of Tussah silkmoth pupae (TG group) and rice (RG group) on the metabolic profile of C. militaris (L.) Link were compared by metabolomics. Meanwhile, the profile of natural C. sinensis (NG group) was also analyzed. The functions of these metabolites from different groups and cordycepin were tested using breast cancer cells and an animal model. 292 metabolites were detected, including 51, 31 and 23 unique metabolites from the TG, RG and NG groups, respectively. The level of 3-deoxyadenosine (cordycepin with anti-tumor activity) was highest in the TG group. Tussah silkmoth pupae induced the biosynthesis of cordycepin and unsaturated fatty acids, which may be beneficial in the prevention of breast cancer. The TG group and cordycepin had significant inhibitory activities on breast cancer cells and in animal models when compared with the two other groups. Tussah silkmoth pupae improved the metabolic profile of C. militaris (L.) Link, which has more pharmaceutical metabolites than C. sinensis. Tussah silkmoth pupae improved the metabolic profile of Cordyceps militaris (L.) Link by upregulating 3-deoxyadenosine (with anti-tumor activity) and insulin secretion.![]()
