Abstract
The incidence and prevalence of diabetes mellitus (DM) are increasing worldwide, and the resulting cardiac complications are the leading cause of death. Among these complications is diabetes-induced cardiomyopathy (DCM), which is the consequence of a pro-inflammatory condition, oxidative stress and fibrosis caused by hyperglycemia. Cardiac remodeling will lead to an imbalance in cell survival and death, which can promote cardiac dysfunction. Since the conventional treatment of DM generally does not address the prevention of cardiac remodeling, it is important to develop new alternatives for the treatment of cardiovascular complications induced by DM. Thus, therapy with mesenchymal stem cells has been shown to be a promising approach for the prevention of DCM because of their anti-apoptotic, anti-fibrotic and anti-inflammatory effects, which could improve cardiac function in patients with DM.

Abstract
Background and Objectives The relationship between vascular damage and diabetes mellitus was exploited using avocado seed extracts. The purpose of the study was to understand the therapeutic relevance of glycosides compared to standard vascular and anti-diabetic drugs. Constituent Avocado Seed Glycosides (ASG) were analysed and administered to rats with Diabetes-Induced Vascular Damage (DIVD). Methods The rats were first administered with streptozotocin and screened after seven days for alterations in blood glucose, insulin, vascular cell adhesion molecule (VCAM-1), Von Willebrand factor (VWF), Renin-Angiotensin-Aldosterone System (RAS), eNOx, and endothelin-1 (ET-1). Only rats that satisfied these criteria were recruited and treated with either glibenclamide, met.su + losart, or 200 mg/kg body weight ASG for 28 days. Results There was an abundance of digitoxin (13.41 mg/100g), digoxin (17.98 mg/100g), avicularin (165.85 mg/100g), and hyperoside (282.51 mg/100g). ASG or met.su + losart exhibited slight modulatory properties on glucose homeostasis. Rats with DIVD showed elevated renin, angiotensin, VCAM-1 and Lp-PLA2 levels but slightly decreased with glibenclamide treatment and normalized with ASG or met.su + losart administration. All treatments normalized Hcy levels. DIVD caused the overproduction of CnT, LDH, Crt-K, LDL-c, TG, and TC and suppressed HDL-c but was completely normalized by the ASG. Water intake remained altered in treated rats. Conclusion The ASG had no relevant effect on glucose homeostasis during DIVD but showed significant vasoprotective properties.

Abstract
Background: Endothelial dysfunction (ED) plays a key role in the development and progression of microvascular and macrovascular complications in pediatrics with type 1 diabetes mellitus (T1DM). Coenzyme Q10 (CoQ10) is a nutraceutical with a known anti-inflammatory and anti-oxidant activity. This study was conducted to evaluate the potential effect of CoQ10 on ED and various metabolic parameters. Methods: This prospective randomized open-label pilot study was conducted on 49 T1DM pediatric patients. Seven healthy non-diabetic pediatric subjects who didn't receive treatment were included as a control group. Eligible patients were randomly allocated into either group I (n = 25); received 100 mg of CoQ10 in addition to standard treatment or group II (n = 24); received standard treatment only. The levels of; soluble intracellular adhesion molecule-1 (sICAM-1), glycated hemoglobin (HbA1c), fasting blood glucose (FBG), lipid profile, serum creatinine and liver function tests were assessed for both groups at baseline and after 3 months of treatment. Results: At baseline, compared to an age-matched healthy control group sICAM-1 levels were significantly elevated in group II diabetic patients (276.5 (231.6-320.66) vs 221.8 (177.9-267.1 ng/ml), p = 0.042. After 3 months of treatment no significant difference was observed in sICAM-1, HbA1c, FBG, lipid profile, serum creatinine and liver function tests between the two study groups. A positive correlation was found between sICAM-1 and HbA1c throughout the study (r = 0.308, p = 0.0054). Conclusion: Administration of CoQ10 for 3 months in T1DM pediatric patients was well tolerated but had no favorable effect on ED or metabolic parameters.

Abstract
Inflammation and oxidative stress are linked to type 2 diabetes mellitus (T2DM). In this work, we analyzed patients' blood markers of antioxidant capacity, oxidative stress and inflammation in individuals with T2DM, in pre-diabetes state (pre-DM) and controls without diabetes. Patients were divided into three groups, according to glycated hemoglobin A1c (HbA1c): <7%, 7-9%, and >9%. Superoxide dismutase (SOD) and glutathione peroxidase (GPX) activities, total thiols, nitric oxide (•NO), tumor necrosis factor alpha (TNF-α) and intercellular adhesion molecule 1 (ICAM-1) levels of the individuals were measured. Plasma SOD activity was higher in T2DM subjects compared to the controls. While total thiols levels were lower in T2DM groups when compared to pre-DM, the values remained unchanged when compared to controls. ICAM-1 levels of T2DM groups were lower than in controls, while GPx activity, •NO, and TNF-α levels were similar among all groups. A positive correlation was found between SOD and HbA1c levels. Concluding, individuals with T2DM present altered SOD activity, total thiols, and ICAM-1 levels, which might contribute to further complications. There is a positive correlation between SOD activity and HbA1c levels. No apparent correlation exists between total thiols and ICAM-1 levels and with any other of the parameters evaluated in this study.

Abstract
Oral mucositis (OM) is one of the main side effects of the head and neck cancer treatment, particularly radiotherapy and/or chemotherapy. OM is characterized by ulcers, erythema, dysphagia, xerostomia, and increased susceptibility to opportunistic infections. In the perspective of finding pharmacological therapies to prevent inflammation and ulceration of OM, the investigation of the pleiotropic effect of commercial drugs is needed, among them gliclazide, an antidiabetic drug. This study aimed to evaluate the effect of gliclazide in an experimental OM model induced by 5-fluorouracil. Male hamsters were pre-treated with oral gliclazide (1, 5, or 10 mg/kg) for 10 days. Cheek pouch samples were subjected to histopathological and immunohistochemical analysis (COX2, iNOS, MMP-2, NFκB P65, GPx) and imunofluorescence (P-selectin). IL-1β and TNF-α levels, Myeloperoxidase activity (MPO) and malondialdehyde (MDA) levels were investigated by ultraviolet-visible spectroscopy analysis. NFκB NLS P50 protein levels were analyzed by western blotting. The group treated with gliclazide at a dose of 10 mg/kg showed presence of erythema, no evidence of erosion, and absence of mucosal ulceration with a score of 1 (1–2) (p < 0.01). Histopathological data for the group treated with gliclazide 10 mg/kg showed re-epithelialization, discrete mononuclear inflammatory infiltrate and absence of hemorrhage, edema, ulcers and abscesses with a score of 1 (1–1) (p < 0.01). Treatment with gliclazide 10 mg/kg reduced MPO activity (p < 0.001), MDA levels (p < 0.001) and NFκB NLS P50 (p < 0.05) protein levels, resulting in low immunostaining to Cox-2, iNOS (p < 0.05), NFκB P65 (p < 0.05), and negative immunoreaction to MMP-2 (p < 0.001). However, it appeared that for Gpx1, the staining was restored in the GLI 10-FUT group compared with 5FUT/saline (p < 0.05). Immunofluorescence revealed decreased levels of P-selectin (p < 0.001) after treatment with gliclazide 10 mg/kg (p < 0.05). In summary, gliclazide accelerated mucosal recovery and reduced oxidative stress and inflammation in the 5-FU-induced OM in hamsters.

Abstract
AIMS Sulfonylureas are well positioned in treating type 2 diabetes, after lifestyle modification and metformin. The sulfonylurea gliclazide was given preference over glibenclamide in older people with type 2 diabetes in the World Health Organization model list of essential medicines. Consequently, a systematic review and meta-analysis of randomized controlled trials of the efficacy and safety of gliclazide versus other oral insulinotropic agents (sulfonylureas, dipeptidyl peptidase-4 inhibitors, and glinides) was performed. METHODS Two reviewers searched MEDLINE for studies of ≥12 weeks duration in adults with type 2 diabetes. The key search word was "gliclazide", filtered with "randomized controlled trial", "human" and "19+ years". Differences were explored in mean change in glycated hemoglobin (HbA(1c)) from baseline (primary outcome) and risk of hypoglycemia (secondary outcome) between gliclazide and other oral insulinotropic agents; and other sulfonylureas. RESULTS Nine out of 181 references reported primary outcomes, of which 7 reported secondary outcomes. Gliclazide lowered HbA1c more than other oral insulinotropic agents, with a weighted mean difference of -0.11% (95%, CI -0.19 to -0.03%, P=0.008, I(2)=60%), though not more than other sulfonylureas (-0.12%; 95%, CI -0.25 to 0.01%, P=0.07, I(2)=77%). Risk of hypoglycemia with gliclazide was not different to other insulinotropic agents (RR 0.85; 95%, CI 0.66 to 1.09, P=0.20, I(2)=61%) but significantly lower than other sulfonylureas (RR 0.47; 95%, CI 0.27 to 0.79, P=0.004, I(2)=0%). CONCLUSION Compared with other oral insulinotropic agents, gliclazide significantly reduced HbA1c with no difference regarding hypoglycemia risk. Compared with other sulfonylureas, HbA1c reduction with gliclazide was not significantly different, but hypoglycemia risk was significantly lower.

Abstract
OBJECTIVES To summarize data supporting the effects of antidiabetes agents on glucose control and cardiovascular risk factors in patients with type 2 diabetes. METHODS Studies reporting on the effects of antidiabetes agents on glycemic control, body weight, lipid levels, and blood pressure parameters are reviewed and summarized for the purpose of selecting optimal therapeutic regimens for patients with type 2 diabetes. RESULTS National guidelines recommend the aggressive management of cardiovascular risk factors in patients with type 2 diabetes, including weight loss and achieving lipid and blood pressure treatment goals. All antidiabetes pharmacotherapies lower glucose; however, effects on cardiovascular risk factors vary greatly among agents. While thiazolidinediones, sulfonylureas, and insulin are associated with weight gain, dipeptidyl peptidase-4 inhibitors are considered weight neutral and metformin can be weight neutral or associated with a small weight loss. Glucagon-like peptide-1 receptor agonists and amylinomimetics (e.g. pramlintide) result in weight loss. Additionally, metformin, thiazolidinediones, insulin, and glucagon-like peptide-1 receptor agonists have demonstrated beneficial effects on lipid and blood pressure parameters. CONCLUSION Management of the cardiovascular risk factors experienced by patients with type 2 diabetes requires a multidisciplinary approach with implementation of treatment strategies to achieve not only glycemic goals but to improve and/or correct the underlying cardiovascular risk factors.

Abstract
BACKGROUND To compare the compliance and efficacy among three treatment modalities in patients of type 2 diabetes with fairly good islet function. METHODS This 38-month open, randomized, prospective study enrolled 536 subjects (HbA1c 9.4+/-0.8%). Patients were divided into three groups including continual insulin injection (I), continual secretagogue administration (S) and alternation of two-month insulin injection and four-month secretagogue treatment (A). At baseline and every three months, HbA1c was measured and a standard bread meal test (100g) was performed. RESULTS HbA1c were better controlled in both groups I and A than in S (6.9+/-0.3%, 6.8+/-0.3% vs. 7.6+/-0.5%). Hypoglycemia incidence was much lower in group A than that in I (0.8 times/patient/month vs. 2.4 times/patient/month) also with less weight gain (1.6 kg vs. 2.8 kg/patient/year). From the standard bread meal test, patients in group A got the greatest increment of 2-h C-peptide. Inquiry from all subjects showed that alternate strategy was welcomed by most of them considering for convenience and efficacy. CONCLUSIONS Alternate insulin-secretagogue treatment can effectively reduce HbA1c and help to improve islet function with reduced risk of hypoglycemia and weight gain under good compliance.

Abstract
The aim of this study is to investigate the correlation of high-sensitivity C-reactive protein and E-selectin with clinical manifestations and plaque characteristics in 88 patients (69 with and 19 without neurological symptoms) with high-grade stenosis of the carotid bifurcation who underwent endarterectomy. The grade of stenosis was quantified by duplex ultrasonography and digital subtraction angiography. Preoperatively, serum high-sensitivity C-reactive protein and E-selectin were measured. Postoperatively, carotid plaque morphology was established according to the American Heart Association classification. High-sensitivity C-reactive protein levels were significantly ( P < .001) higher in symptomatic than in asymptomatic patients, as well as in patients with unstable compared with those with stable plaques ( P < .001). Serum high-sensitivity C-reactive protein levels correlated significantly ( P < .05) with macrophage count on the plaque. In conclusion, serum high-sensitivity C-reactive protein levels are associated with presence of neurological symptoms and plaque instability in patients with high-grade stenosis of the carotid bifurcation.
