Platelet hyperactivation is involved in the established prothrombotic condition of metabolic diseases such as Type 2 Diabetes Mellitus (T2DM) and familial hypercholesterolemia (HC), justifying the therapy with aspirin, a suppressor of thromboxane synthesis through the irreversible inhibition of cyclooxygenase-1 (COX-1), to prevent cardiovascular diseases. However, some patients on aspirin show a higher than expected platelet reactivity due, at least in part, to a pro-oxidant milieu. The aim of this study was to investigate platelet reactivity in T2DM (n = 103) or HC (n = 61) patients (aspirin, 100 mg/day) and its correlation with biomarkers of redox function including the superoxide anion scavenger superoxide dismutase (SOD) and the in vivo marker of oxidative stress urinary 8-iso-prostaglandin F2α. As results, in T2DM and HC subjects the prevalence of high on-aspirin platelet reactivity was comparable when both non-COX-1-dependent and COX-1-dependent assays were performed, and platelet reactivity is associated with a lower SOD activity that in a stepwise linear regression appears as the only predictor of platelet reactivity. To conclude, in T2DM and HC, similarly, the impairment of redox equilibrium associated with a decrease of SOD activity could contribute to a suboptimal response to aspirin.

Background: The present review article considers some chronic diseases of vascular and metabolic genesis, the causes of which may be mitochondrial dysfunction. Very often, in the long course of the disease, complications may occur, leading to myocardial infarction or ischemic stroke and as a result, death.In particular, a large percentage of human deaths nowadays belongs to cardiovascular diseases such as coronary heart disease (CHD), arterial hypertension, cardiomyopathies and type 2 diabetes mellitus. Objective: The aim of the present review was the analysis of literature sources, devoted to an investigation of a link of mitochondrial DNA mutations with chronic diseases of vascular and metabolic genesis, Results: The analysis of literature indicates the association of the mitochondrial genome mutations with coronary heart disease, type 2 diabetes mellitus, hypertension and various types of cardiomyopathies. Conclusion: The detected mutations can be used to analyze the predisposition to chronic diseases of vascular and metabolic genesis. They can also be used to create molecular-cell models necessary to evaluate the effectiveness of drugs developed for treatment of these pathologies. MtDNA mutations associated withthe absence of diseases of vascular and metabolic genesis could be potential candidates for gene therapy of diseases of vascular and metabolic genesis.

*** Oxidative stress in patients with type 2 diabetes mellitus treated with metformin ***AIMS: To evaluate oxidative stress parameters in patients with type 2 diabetes mellitus treated with metformin, relating these values to its side effects, plasma levels, glycemic control, diabetic complications, lipid profile, and the influence of pharmacotherapeutic follow-up.METHODS: Patients with type 2 diabetes mellitus, on metformin and in pharmacotherapeutic follow-up for four months, were evaluated. The pharmacotherapeutic follow-up consisted in providing information and answering patients’ questions about medication and disease. In addition, administration times, dosages, and presence or absence of side effects related to the use of metformin were verified. Glycemic and lipid profile, oxidative stress (superoxide dismutase and malondialdehyde) and plasma metformin were evaluated. Pearson’s correlation and Spearman’s correlation were performed to evaluate the relationship between the variables at the beginning of the study. The independent t-test and Mann-Whitney U test were used to assess the difference between the groups with and without diabetic complications. The range of values between the beginning and  end of the study was evaluated using Student’s t-test or Wilcoxon U test. The significance level was set at 5%.RESULTS: The initial sample consisted of 49 patients aged 59±9 years with a body mass index of 29.8±5.1 kg/m2, who have had diabetes for a median time of 36 months (interquartile range of 1-240) and have been on metformin for a median time of 36 months (interquartile range of 1-180). Twenty-five patients left the study between the second and fourth meetings. Malondialdehyde levels differed between before and after pharmacotherapeutic follow-up, being positively correlated with blood glucose, glycohemoglobin, and triglyceride level, and negatively correlated with metformin and superoxide dismutase. Blood glucose, glycohemoglobin, and malondialdehyde levels increased, whereas metformin levels decreased in the group with diabetic complications, and there was a correlation between malondialdehyde and the number of diabetic complications per patient.CONCLUSIONS: In this sample of patients with type 2 diabetes mellitus treated with metformin, oxidative stress was more pronounced in those with poor glycemic control and diabetic complications.

Alpha Glucosidase

Type-2 diabetes mellitus is one of the most prevalent metabolic diseases in the world, and is characterized by hyperglycemia (i.e., high levels of glucose in the blood). Alpha-glucosidases are enzymes in the digestive tract that hydrolyze carbohydrates into glucose. One strategy that has been developed to treat type-2 diabetes is inhibition of the activity of alpha-glucosidases using synthetic drugs. However, these inhibitors are usually associated with gastrointestinal side effects. Therefore, the development of inhibitors from natural products offers an alternative option for the control of hyperglycemia. In recent years, various studies have been conducted to identify alpha-glucosidases inhibitors from natural sources such as plants, and many candidates have transpired to be secondary metabolites including alkaloids, flavonoids, phenols, and terpenoids. In this review, we focus on the alpha-glucosidases inhibitors found in common vegetable crops and the major classes of phytochemicals responsible for the inhibitory activity, and also as potential/natural drug candidates for the treatment of type-2 diabetes mellitus. In addition, possible breeding strategies for production of improved vegetable crops with higher content of the inhibitors are also described.

Introduction. Uncontrolled diabetes mellitus (DM) is related to skin disorders, particularly dry skin. Pathogenesis of dry skin in type 2 diabetes mellitus (T2DM) rises from the chronic hyperglycemia causing an increase in advanced glycation end-products (AGEs), proinflammatory cytokines, and oxidative stress. Combination of oral and topical Centella asiatica (CA) is expected to treat dry skin in T2DM patients more effectively through decreasing N(6)-carboxymethyl-lysine (CML) and interleukin-1α (IL-1α) and increasing superoxide dismutase (SOD) activity. Methods. A three-arm prospective, double-blind, randomized, controlled study was performed to evaluate the efficacy of the oral and topical CA extract in 159 T2DM patients with dry skin. The subjects were divided into the CA oral (CAo) 2 × 1.100 mg + CA topical (CAt) 1% ointment group, oral placebo (Plo) + CAt group, and Plo and topical placebo (Plt) group. Dry skin assessment was performed on day 1, 15, and 29, while evaluation of CML, IL-1α, and SOD activity was on day 1 and 29. Result. Effectivity of CAo + CAt combination was assessed based on HbA1c and random blood glucose (RBG). In well-controlled blood glucose, on day 29, the percentage of SRRC decrement was greater in the CAo + CAt group compared to the control group (p=0.04). SCap value in the CAo + CAt group was greater than that in the control group (p=0.01). In the partially controlled blood glucose, increment of SOD activity in the CAo + CAt group was greater than that in the control group (p=0.01). There were medium-to-strong correlation between CML with SOD (r = 0.58, p<0.05) and IL-1α with SOD (r = 0.70, p<0.05) in well-controlled blood glucose. Systemic and topical adverse events were not significantly different between groups. Conclusion. CAo and CAt combination can be used to significantly improve dry skin condition through increasing SOD activity in T2DM patients with controlled blood glucose.

Type 2 diabetes mellitus (T2DM) and other metabolic diseases are essential links in the structure of morbidity and mortality in the modern world. The accepted strategy for the correction of T2DM and insulin resistance is drug therapy aimed at delivering insulin from the outside, stimulating the secretion of own insulin and reducing the concentration of blood glucose. However, modern studies demonstrate a great potential for the use of gene therapy approaches for the correction of T2DM and insulin resistance. In the present review, the main variants of plasmid gene therapy of T2DM using the genes of adiponectin and type 1 glucagon-like peptide, as well as the main variants of viral gene therapy of T2DM using the genes of type 1 and leptin are considered. T2DM gene therapy is currently not ready to enter into routine clinical practice, but, subject to improvements in delivery systems, it can be a powerful link in combination therapy for diabetes.

Introduction: Type 2 diabetes mellitus (T2DM) is a group of metabolic diseases depicted by crippled insulin release by the pancreas and insulin resistance of body tissues.  Objectives: The main objective of the study is to analyse the prevalence of type 2 diabetes mellitus and pre-diabetes using HbA1c. Material and Methods: This cross sectional study was conducted in Islam Medical College Sialkot during 2020 to 2021. A special questionnaire concerning family history and health-related information was filled for all participants by direct interviews with the researchers. People previously diagnosed with diabetes or hemoglobinopathies were ruled out from the study. Blood samples were collected from all subjects using EDTA tubes and centrally analyzed for HbA1c. Results: The data was collected from 200 patients of both genders. In all, 200 participants were found to be currently diabetic, giving an overall prevalence of current condition to be 24.6% (95% CI 21.90 - 27.49) in the study population. History of disease was reported by 31.5% participants (P < 0.001). Conclusion: It is concluded that adjustments in platelet files are believed to be measurably connected with diabetes and its intricacies. The prevalence of type 2 diabetes and pre-diabetes is much higher than previously thought in Pakistan.

Transcriptional Responses

In both developing and industrialized Countries, the growing prevalence of Type 2 Diabetes Mellitus (T2DM) and the severity of its related complications make T2DM one of the most challenging metabolic diseases worldwide. The close relationship between genetic and environmental factors suggests that eating habits and unhealthy lifestyles may significantly affect metabolic pathways, resulting in dynamic modifications of chromatin-associated proteins and homeostatic transcriptional responses involved in the progression of T2DM. Epigenetic mechanisms may be implicated in the complex processes linking environmental factors to genetic predisposition to metabolic disturbances, leading to obesity and type 2 diabetes mellitus (T2DM). Endothelial dysfunction represents an earlier marker and an important player in the development of this disease. Dysregulation of the endothelial ability to produce and release vasoactive mediators is recognized as the initial feature of impaired vascular activity under obesity and other insulin resistance conditions and undoubtedly concurs to the accelerated progression of atherosclerotic lesions and overall cardiovascular risk in T2DM patients. This review aims to summarize the most current knowledge regarding the involvement of epigenetic changes associated with endothelial dysfunction in T2DM, in order to identify potential targets that might contribute to pursuing “precision medicine” in the context of diabetic illness.
