Background: Unmanaged type 2 diabetes mellitus has dangerous consequences, such as neuropathy. Oxidative stress and inflammatory factors play an important role in the development of diabetic neuropathy. Diabetics are prone to mild cognitive impairment, which is a neurological disease. The aim of this study was to investigate the effects of quercetin as a functional food and oxidative agents and inflammatory factors of low-level laser.Methods: In this study, 60 elderly volunteers were selected: 30 normal as a control group and 30 with type 2 diabetes mellitus and mild cognitive impairment. The average age was 75 years old. Groups of diabetic patients were examined for changes in glucose levels, oxidants, antioxidants and inflammatory factors before and after treatment with quercetin and low-level laser therapy–green laser diode with a wavelength of 532 nm at 100 mw and compared with the control group. Changes in the levels of biochemical parameters were performed according to the instructions of the relevant kits. Results: The results of the obtained data analysis showed that there was a significant difference (P value < 0.05) in the levels of glucose, hydrogen peroxide, advanced glycation end-products, malondialdehyde, oxidized-low density lipoprotein, paraoxonase, lipoprotein lipase, and inflammatory factors including TNF-α, interleukin-1 alpha and interleukin-1 beta between diabetic samples before and after treatment with quercetin and laser from control subject samples. There was no significant difference (P value > 0.05) in inflammatory factors between quercetin-treated, laser-treated and both quercetin and laser treated groups. The synergistic effect of quercetin and laser between the quercetin and laser treated group and the untreated group on changes in the levels of biochemical parameters was observed significantly only in advanced glycation end-products, malondialdehyde, oxidized-low density lipoprotein, and paraoxonase.Conclusion: The results showed that quercetin, laser, and their synergistic effect can play a role in reducing some oxidant factors.Keywords: Quercetin, Low-level laser, Inflammatory factors, Oxidative factors, Diabetes mellitus
Background:Unmanaged diabetes mellitus, as a chronic metabolic disease, has dangerous consequences. The consequences of diabetes can be delayed and controlled by using antioxidants and anti-inflammatory substances in the food compounds.Objective: One of the main objectives of this study was to evaluate thymol administration and low-level laser therapy on the change of inflammatory and, oxidative indicators, and lipid profiles in patients with type 2 diabetes. Another aim was to study the effect of thymol oil extract on dermatitis.Methods:Thirty volunteers with type 2 diabetes and thirty healthy volunteers as controls were selected. Blood samples were taken from all subjects before the study. The diabetic group was divided into four groups: untreated, treated with low-level laser, treated with thymol (25 mg/kg/30 days) and treated with thymol and laser. Glucose, advanced glycation end products, malondialdehyde, oxidized low level laser, reactive oxygen species, peroxide hydrogen, total cholesterol, triglyceride, and inflammatory cytokines such as tumor necrosis factor alpha, interleukin-1 beta and interleukin-1 alpha were measured and compared between diabetic and control groups and within diabetic groups. Thymol gel oil extract (0.5%) was studied in reduction of dermatitis in the feet of the diabetic group.Results:Thymol administration, along with low-level laser therapy, reduced levels of cytokines except for interleukin-1 alpha, total cholesterol, triglycerides, advanced glycation end products, hydrogen peroxide, malondialdehyde, and oxidized low density level lipoprotein (P value < 0.05). The effect of 0.5% thymol oil as a gel on the reduction of dermatitis was not significant.Conclusion:Thymol administration and thymol gel as well as low-level laser therapy, as adjunctive methods, through the reduction of free radicals and oxidative stress can be useful in controlling and reducing the diabetes complications.Keywords: Diabetes mellitus, Thymol, Topical gel, Low-level laser therapy, Dermatitis
Original Research Paper Received 19 September 2015 Accepted 23 October 2015 Available Online 30 November 2015 Nowadays the Computer Aided Engineering (CAE) technique is widely used for improving Noise Vibration Harshness (NVH) performance of vehicles. High complexities in the Body In White (BIW) of vehicles lead the developed CAE models to become complex by which the optimization process will become very hard. Concept modeling could be a suitable replacement to overcome the mentioned limitations. Dynamic characteristics such as natural frequencies and mode shapes could be studied in the early phase of design with very low amount of calculations with the concept model. For this purpose, a developed concept model has been presented for the wheelhouse. The developed concept model uses approximated equivalent beam elements to model the beam like and panels of the structures. Also, the experimental test and numerical model have been utilized for the validation of the developed concept model. Two criteria of natural frequencies and corresponding mode shapes have been considered as the measure of validation. The results showed good correlation with corresponding advanced CAE models as well as experimental tests in low frequency range. The results showed that the developed concept model in this research is a powerful and effective tool to enhance and optimize the NVH performance of the vehicle in the early stage of design.
Background: Squalene, as an isoprene, is one of the components of amaranth oil and makes up about 8% of this oil. Squalene has anti-inflammatory and antioxidant effects that have been considered in many studies. In people with uncontrolled diabetes, there is an increase in total cholesterol and low-density lipoprotein (LDL) alongside a decrease in high-density lipoproteins (HDL).According to studies, squalene can be useful in lowering total cholesterol and triacylglycerol.Objective: The aim of this study was to investigate whether squalene has an effect on lipid profile and a number of oxidative biomarkers in patients with type 2 diabetes.Methods: In the present study, 30 healthy volunteers were selected as the control group and 120 volunteers with type 2 diabetes mellitus (T2DM) were selected. Subjects with diabetes were randomly divided into 4 groups. Group 1 was untreated with squalene and groups 3, 4, and 5 were treated with different doses of squalene for 84 days. Lipid profiles and oxidant biomarkers were examined on days 1, 14, 28, 56, and 84 according to the relevant protocols in all groups.Results: Significant differences (P < 0.05) were observed between control and diabetic groups in the study of cholesterol, triglycerides, LDL, HDL, very low-density lipoproteins (VLDL), oxidized low-density lipoprotein (Ox-LDL), and malondialdehyde. There was a significant difference between the studied groups in the levels of parameters expressed in some different doses and days.At the levels of the parameters expressed in some doses and different days, a significant difference was observed between the groups treated and untreated with squalene.Conclusion: This study shows that squalene as a bioactive compound can be effective to manage certain symptoms of diabetics including HDL, LDL, total cholesterol, and VLDL. From our findings, we observed that squalene consumption over the duration of 84 days resulted in increased levels of HDL in diabetic patients. It also resulted in decreased levels of total cholesterol, LDL, and VLDL in diabetic patients. Keywords: Squalene, lipid profile, oxidative biomarkers, diabetes mellitus
Background: Squalene is a 30-carbon ring hydrocarbon in the triterpene class. Squalene as a bioactive compound has been shown to have several health benefits specifically in the reduction of diabetic symptoms, including anti-inflammatory effects.Objective: The purpose of the study was to examine effect of squalene on specific parameters regarding energy production and inflammation in those with type 2 diabetes mellitus. These parameters included ATP, NAD/NADH, CoQ10, NFκB, IκB-alpha, IκK-alpha, and IκK-beta.Methods: 150 volunteers were selected for this study split into 5 groups. Group 1 contained 30 healthy participants and served as the control. The remaining 120 participants were split into 4 groups containing 30 volunteers each. All the participants in groups 2, 3, 4, and 5 have type 2 diabetes mellitus. Group 2 did not receive any squalene while group 3, group 4, and group 5 all received an oral supplementation of squalene at 200 mg/day, 400 mg/day and 600 mg/day respectively. Participants were prescribed to take the oral supplementation of squalene for a total of 84 days. Blood samples were taken on days 1, 14, 28, 56, and 84 in five time periods. For all participants ATP, NAD/NADH, CoQ10, NFκB, IκB-α, IκK-α and IκK-β levels of all groups were evaluated.Results: Throughout the 84 days there was a statistically significant difference when comparing the healthy group and the diabetic groups in reducing ATP, NAD/NADH and CoQ10 (P < 0.05) and increasing NFκB, IκB-α, IκK-α and IκK-β (P < 0.05). When compared, participants in groups 3, 4, and 5 also showed a statistically significant in the changes of ATP, NFκB, IκB-α, IκK-α and IκK-β levels.Conclusions: Squalene as a bioactive compound can play an important role in reducing inflammatory mediators and increases energy production.Keywords: squalene, diabetes mellitus, ATP production, NAD/NADH, Reactive oxygen species (ROS), CoQ10, NFκB, IkB-α, IκK-α, IκK-β
Introduction: Hyperglycemia in people with diabetes mellitus and its lack of control are associated with irreversible consequences. Glycation of proteins and enzymes, especially antioxidant enzymes in uncontrolled diabetes mellitus, affects these consequences. Consumption of bioactive compounds containing antioxidants and minerals as well as the use of adjunct therapies, such as cold atmospheric plasma therapy, can be effective in preventing and controlling the consequences of diabetes mellitus.Objective: In this research, we investigated whether cold plasma treatment of diabetic samples was effective in altering the activity of oxidative enzymes, some biochemical elements, and biochemical parameters.Methods: Thirty individuals with type 2 diabetes mellitus and 30 healthy individuals, as controls, participated in the study. The samples were exposed to cold argon plasma jet for 10 minutes (by a 10 kHz pulsed DC power supply with an amplitude up to 20.0 kV). The following contents of the serum samples of all participants were evaluated according to the instructions of the used kits before and after the cold argon plasma jet treatment: the activity of catalase, superoxide dismutase, and glutathione peroxidase enzymes; the concentration of glucose, hydrogen peroxide, and selenium binding protein 1 (as an indicator of blood selenium); and the concentration of copper, zinc, iron, and magnesium.Results: The activity of antioxidant enzymes and minerals significantly increased in diabetic samples treated with cold plasma (P value < 0.05). No significant changes were observed in the concentrations of glucose, hydrogen peroxide, or selenium binding protein 1 in diabetic samples treated with cold plasma.Conclusions: Using cold argon plasma jet as an adjunct method, which will reduce the glycation of enzymes and improve some minerals, can reduce the risk of diabetes complications in patients with diabetes mellitus.Keywords:Antioxidant enzymes, Cold plasma, Diabetes mellitus, Minerals.
Background: The study on the control and treatment of type 2 diabetes mellitus, as a growing metabolic disease in the world, is important. Oxidative stress and reactive oxygen species in uncontrolled diabetes can play a role in the consequences of diabetes such as neuropathy and nephropathy. The presence of minerals as bioactive compounds in the diet and their role in antioxidant enzymes can play a role in reducing the oxidative effects of diabetes. Electron beam therapy as an adjunct method can be effective in reducing free radicals and oxidative stress. Objective: The main purpose of this study was to investigate the effect of electron beam therapy on glucose, oxidative markers and some minerals, as bioactive compound, in people with type 2 diabetes mellitus. Methods: The study was performed on 30 volunteers with type 2 diabetes mellitus and 30 healthy volunteers as a control group. Serum samples from diabetic and control groups were assayed for glucose, hydrogen peroxide, reactive oxygen species and minerals such as iron, zinc, copper, magnesium and selenium binding protein before and after electron beam irradiation. ATP levels and NAD/NADH ratio were also evaluated. The mentioned parameters were measured by ELISA and calorimetric methods according to the relevant kit protocol. Electron beam therapy was performed using a linear accelerator. The used amount of energy was 9 MeV. The depth of treatment was 1.5 cm.Results: The results of electron beam therapy showed that the concentrations of glucose, reactive oxygen species, hydrogen peroxide, copper and iron were significantly (P value < 0.05) reduced in diabetics. Zinc levels in this group increased significantly (P value < 0.05). In control group, ATP levels were significantly (P value < 0.05) increased by electron beam therapy.Conclusion: According to the obtained results, electron beam therapy can be effective in reduction of oxidation indexes and thus reducing oxidative stress. Electron beam therapy can be effective in reducing the consequences of diabetes mellitus. Keywords: Electron beam therapy, Oxidative stress, Mineral, Type 2 diabetes mellitus
Background: Type 2 diabetes mellitus is a chronic disease that diminishes the body’s ability to regulate glucose levels due to the lack of insulin produced. In recent studies, squalene has been reported to have beneficial effects for diabetic patients, especially within the liver where the urea cycle takes place.Objective: Our main goal was to evaluate the molecular effects of different doses of squalene on the enzymes, intermediates, and molecules of the urea cycle, in order to determine if squalene has beneficial effects among groups of people with type 2 diabetes mellitus. The enzymes and molecules that are being studied are ornithine transcarbamylase (OTC), arginosuccinate synthetase (ASS), arginase, carbamoyl-phosphate synthetase 1 (CSP1), urea, aspartate, and ammonium ion (NH4+).Methods: In this study, healthy volunteers were categorized as the healthy control (group 1) and volunteers with type 2 diabetes mellitus were selected. The patients with diabetes were divided up into 4 groups. Group 2 consists of the patients that will not be treated with squalene. Groups 3, 4, 5 were treated with 200, 400, 600 mg, respectively. The patients were treated with their respective amounts every 14 days for the duration of 84 days. The enzymes and molecules were measured on days 1, 14, 28, 56, and 84.Results: The squalene-treated diabetic groups were compared to group 2, who was not treated with any squalene to determine the differences between the parameters. Throughout the 84 days, it was observed that NH4+ or ammonium molecules decreased in all treated diabetic patients with high statistical difference (P < 0.05). For the majority of the diabetic patients treated with squalene, there was also a decrease in aspartate. The other parameters did not have consistent significant differences (P > 0.05).Conclusion: Based on the findings of this study, the addition of various doses of squalene to a diabetic patient’s diet decreased the amount of ammonium and aspartate in the body. As ammonium is the direct product of the urea cycle, it is evident that squalene does play a key role in reducing the amount of ammonium in a diabetic patient to a healthier level.Keywords: Diabetes mellitus, urea cycle, enzyme, metabolite, squalene.
