    Full Text Available BackgroundThe aim of this study is to observe the outcome of critically ill patients in relation to blood glucose level at admission and to determine the optimal range of blood glucose at admission predicting lower hospital mortality among critically ill patients.MethodsWe conducted a retrospective cohort study of a total 1,224 subjects (males, 798; females, 426 admitted to intensive care unit (ICU from 1 January 2009 to 31 December 2010. Blood glucose levels at admission were categorized into four groups (group 1, <100 mg/dL; group 2, 100 to 199 mg/dL; group 3, 200 to 299 mg/dL; and group 4, ≥300 mg/dL.ResultsAmong 1,224 patients, 319 patients were already known diabetics, and 296 patients died in ICU. Five hundred fifty-seven subjects received insulin therapy, and 118 received oral hypoglycemic agents. The overall mortality rate was 24.2% (296 patients. The causes of death and mortality rates of diabetic patients were not different from nondiabetic subjects. The mortality curve showed J shape, and there were significant differences in mortality between the groups of blood glucose levels at admission. Group 2 had the lowest mortality rate (P<0.05.ConclusionThese results suggest that serum glucose levels upon admission into ICU is associated with clinical outcomes in ICU patients. Blood glucose level between 100 and 199 mg/dL at the time of ICU admission could predict lower hospital mortality among critically ill patients.

    This study was designed to assess changes in glucose metabolism in rats administered single or repeated doses of MDMA. Two different experiments were performed: (1) A single-dose study with four groups receiving 20 mg/kg, 40 mg/kg, saline or heat, and (2) a repeated-dose study with two groups receiving three doses, at intervals of 2 h, of 5 mg/kg or saline. Rats were imaged using a dedicated small-animal PET scanner 1 h after single-dose administration or 7 days after repeated doses. Glucose metabolism was measured in 12 cerebral regions of interest. Rectal temperature and blood glucose were monitored. Peak body temperature was reached 1 h after MDMA administration. Blood glucose levels decreased significantly after MDMA administration. In the single-dose experiment, brain glucose metabolism showed hyperactivation in cerebellum and hypo-activation in the hippocampus, amygdala and auditory cortex. In the repeated-dose experiment, brain glucose metabolism did not show any significant change at day 7. These results are the first to indicate that MDMA has the potential to produce significant hypoglycaemia. In addition, they show that MDMA alters glucose metabolism in components of the motor, limbic and somatosensory systems acutely but not on a long-term basis. (orig.)

    It is well recognized that poor perioperative blood glucose (BG) control can increase the risk of infection, cardiovascular accidents, and even death in patients undergoing cardiac surgery. Since it has been reported that tight BG control (80-110 mg/dL) yields better outcomes in critically ill patients, it became a standard of care to control BG using intravenous insulin infusion in ICU. However, it has been debated in terms of the optimal target range whether a strict control with intensive ...

    Although the effects on prognosis of blood glucose level variability have gained increasing attention, it is unclear whether blood glucose level variability itself or the manifestation of pathological conditions that worsen prognosis. Then, previous reports have not been published on variability models of perioperative blood glucose levels. The aim of this study is to establish a novel variability model of blood glucose concentration using an artificial pancreas. We maintained six healthy, male beagles. After anesthesia induction, a 20-G venous catheter was inserted in the right femoral vein and an artificial pancreas (STG-22, Nikkiso Co. Ltd., Tokyo, Japan) was connected for continuous blood glucose monitoring and glucose management. After achieving muscle relaxation, total pancreatectomy was performed. After 1 h of stabilization, automatic blood glucose control was initiated using the artificial pancreas. Blood glucose level varied for 8 h, alternating between the target blood glucose values of 170 and 70 mg/dL. Eight hours later, the experiment was concluded. Total pancreatectomy was performed for 62 ± 13 min. Blood glucose swings were achieved 9.8 ± 2.3 times. The average blood glucose level was 128.1 ± 5.1 mg/dL with an SD of 44.6 ± 3.9 mg/dL. The potassium levels after stabilization and at the end of the experiment were 3.5 ± 0.3 and 3.1 ± 0.5 mmol/L, respectively. In conclusion, the results of the present study demonstrated that an artificial pancreas contributed to the establishment of a novel variability model of blood glucose levels in beagles.

    Regardless of the diabetic status of patients with coronary artery disease, hyperglycemia and hypoglycemia are adversely associated with cardiovascular events. The relationship between glucose levels and increased mortality risk in acute myocardial infarction has been shown through various glucose metrics; however, there is a dearth of multivariate analysis of the relationship between elective coronary angioplasty and preprocedural blood glucose levels.

  10. The Effects of Blood Glucose Levels on Cognitive Performance: A Review of the Literature

    2007-01-01

    The purpose of this review paper is to discuss the research literature on the effects of blood glucose levels on executive and non-executive functions in humans. The review begins with a brief description of blood glucose, how it has been studied, previous syntheses of prior studies, and basic results regarding the role of blood glucose on cognitive functioning. The following sections describe work that investigated the effect of blood glucose on both non-executive and executive functions (e.g., sensory processing, psychomotor functioning, attention, vigilance, memory, language and communication, judgement and decision-making, and complex task performance). Within each section, summaries of the findings and challenges to the literature are included. Measurement conversions of blood glucose levels, blood glucose values, and associated symptoms are depicted. References to the types of tests used to investigate blood glucose and cognitive performance are provided. For more detailed descriptions of references within (and in addition to) this paper, an annotated bibliography is also provided. Several moderator variables including individual differences and contextual variables related to the effects of blood glucose levels on performance (e.g., age, gender, time of day, familiarity with the task and symptom awareness, expectancy effects, dose dependent effects, time dependent effects, task specific effects, rising and falling blood glucose levels, and speed and/or accuracy trade-offs) are addressed later in the paper. Some suggestions for future experimental methodologies are also made.

    In the present study, we examined the effect of pertussis toxin (PTX) administered centrally in a variety of stress-induced blood glucose level. Mice were exposed to stress after the pretreatment of PTX (0.05 or 0.1 µg) i.c.v. or i.t. once for 6 days. Blood glucose level was measured at 0, 30, 60 and 120 min after stress stimulation. The blood glucose level was increased in all stress groups. The blood glucose level reached at maximum level after 30 min of stress stimulation and returned to a normal level after 2 h of stress stimulation in restraint stress, physical, and emotional stress groups. The blood glucose level induced by cold-water swimming stress was gradually increased up to 1 h and returned to the normal level. The intracerebroventricular (i.c.v.) or intrathecal (i.t.) pretreatment with PTX, a Gi inhibitor, alone produced a hypoglycemia and almost abolished the elevation of the blood level induced by stress stimulation. The central pretreatment with PTX caused a reduction of plasma insulin level, whereas plasma corticosterone level was further up-regulated in all stress models. Our results suggest that the hyperglycemia produced by physical stress, emotional stress, restraint stress, and the cold-water swimming stress appear to be mediated by activation of centrally located PTX-sensitive G proteins. The reduction of blood glucose level by PTX appears to due to the reduction of plasma insulin level. The reduction of blood glucose level by PTX was accompanied by the reduction of plasma insulin level. Plasma corticosterone level up-regulation by PTX in stress models may be due to a blood glucose homeostatic mechanism. PMID:27610033

  12. Intraoperative blood glucose levels in neurosurgical patients : an evaluation of two fluid regimens.

    Full Text Available Based on the evidence that hyperglycaemia aggravates ischaemic cerebral injury, it has been suggested that blood glucose levels be kept within 200 mg/dL during intracranial neurosurgery. Hypoglycaemia, however, can be a serious problem if glucose-containing solutions are avoided during the first four hours, as suggested in some studies. In order to explore the possibility of administering glucose in moderation so that the blood glucose levels are within acceptable limits, but at the same time the risk of hyoglycaemia is eliminated, we compared two intraoperative fluid regimens. Of the 52 neurosurgical patients studied, 32 patients received alternately 500 ml of 5% dextrose in normal saline and Ringer′s lactate (DNS/RL Group and 18 patients received alternately 500 ml of Ringer′s lactate and normal saline (RL/NS Group. Blood glucose concentrations were determined at the end of each unit of fluid, until the patient received 4 units of fluid. In the DNS/RL group, blood glucose values peaked with the administration of each unit of DNS and tended to return towards the baseline with the subsequent RL, but remained higher than the previous control value. In the RL/NS group, there was a progressive increase in blood glucose values throughout the study period, but the increase was not statistically significant. The blood glucose levels were significantly different between the two groups after each unit of fluid except at the end of the fourth unit. Two patients in the RL/NS group had hypoglycaemia. In conclusion, the DNS/RL regimen maintains blood glucose levels within acceptable limits while avoiding the risk of hyperglycaemia. Withholding glucose completely, lowers blood glucose levels, but carries a risk of hypoglycaemia in some patients.

    In FDG-PET for abdominal malignancy, the liver may be assumed as an internal standard for grading abnormal FDG uptake both in early images and in delayed images. However, physiological variables of FDG uptake by the liver, especially the effects of blood glucose level, have not yet been elucidated. Methods: FDG-PET studies of 70 patients examined at 50 to 70 min after injection (60{+-}10 min: early images) and of 68 patients examined at 80 to 100 min after injection (90{+-}10 min: delayed images) were analyzed for liver FDG uptake. Patients having lesions in the liver, spleen and pancreas; patients having bulk tumor in other areas; and patients early after chemotherapy or radiotherapy were excluded; also, patients with blood glucose level over 125 mg/dl were excluded. Results: Mean standardized uptake value (SUV) of the liver, blood glucose level and sex showed no significant differences between early images and delayed images. However, liver SUV in the delayed image showed a larger variation than that in the early image and showed significant correlation to blood glucose level. The partial correlation coefficient between liver SUV and blood glucose level in the delayed image with adjustment for sex and age was 0.73 (P<.0001). Multivariate regression coefficient (95% confidence interval) of blood glucose was 0.017 (0.013-0.021). Conclusion: Blood glucose level is an important factor affecting the normal liver FDG uptake in nondiabetic patients. In the case of higher glucose level, liver FDG uptake is elevated especially in the delayed image. This may be due to the fact that the liver is the key organ responsible for glucose metabolism through gluconeogenesis and glycogen storage.

    The current study investigated the relationships between blood glucose levels, mild food deprivation, sympathetic arousal, and cognitive processing efficiency. Subjects (n = 82) were randomly assigned to four experimental conditions, comprising combined manipulations of food deprivation and incentive motivation. Baseline and mid-session measurements of blood glucose, blood pressure and pulse rate were taken. Subjects completed a number of measures of cognitive processing efficiency and self report measures of affective and somatic state. Although glucose levels were lowered following food deprivation, there was no significant detrimental effect of food deprivation on task performance. However, improved recognition memory processing times were associated with deprivation. Incentive motivation was associated with faster simple reaction times and higher diastolic blood pressure. There were no significant relationships between glucose levels and task performance, further supporting the hypothesis that the brain is relatively invulnerable to short food deprivation.

    We developed a new model of glucose dynamics. The model calculates blood glucose level as a function of transcapillary glucose transport. In previous studies, we validated the model with animal experiments. We used analytical method to determine model parameters. In this study, we validate the model with subjects with type 1 diabetes. In addition, we combine the analytic method with meta-differential evolution. To validate the model with human patients, we obtained a data set of type 1 diabetes study that was coordinated by Jaeb Center for Health Research. We calculated a continuous blood glucose level from continuously measured interstitial fluid glucose level. We used 6 different scenarios to ensure robust validation of the calculation. Over 96% of calculated blood glucose levels fit A+B zones of the Clarke Error Grid. No data set required any correction of model parameters during the time course of measuring. We successfully verified the possibility of calculating a continuous blood glucose level of subjects with type 1 diabetes. This study signals a successful transition of our research from an animal experiment to a human patient. Researchers can test our model with their data on-line at https://diabetes.zcu.cz.

    We assessed the impact of thinking of a current romantic partner on acute blood glucose responses and positive affect over a short period of time. Participants in romantic relationships were randomly assigned to reflect on their partner, an opposite-sex friend, or their morning routine. Blood glucose levels were assessed prior to reflection, as well as at 10 and 25 min postreflection. Results revealed that individuals in the routine and friend conditions exhibited a decline in glucose over time, whereas individuals in the partner condition did not exhibit this decline (rather, a slight increase) in glucose over time. Reported positive affect following reflection was positively associated with increases in glucose, but only for individuals who reflected on their partner, suggesting this physiological response reflects eustress. These findings add to the literature on eustress in relationships and have implications for relationship processes.

    Experimental studies disrupting sleep and epidemiologic studies of short sleep durations indicate the importance of deeper and longer sleep for cardiometabolic health. We examined the potential beneficial effects of lengthening the first uninterrupted sleep period (FUSP) on blood glucose. Long-term data (≥3 months of treatment) were derived from three clinical trials, testing low-dose (10-100 µg) melt formulations of desmopressin in 841 male and female nocturia patients (90 % of which had nocturnal polyuria). We performed post hoc multiple regression with non-fasting blood glucose as dependent variable and the following potential covariates/factors: time-averaged change of FUSP since baseline, age, gender, race, ethnicity, baseline glucose, baseline weight, change in weight, patient metabolic status (normal, metabolic syndrome, type II diabetes), dose, follow-up interval, and time of random glucose sampling. Increases in FUSP resulted in statistically significant reductions in blood glucose (p = 0.0131), even after controlling for all remaining covariates. Per hour increase in time to first void was associated with glucose decreases of 1.6 mg/dL. This association was more pronounced in patients with increased baseline glucose levels (test of baseline glucose by FUSP change interaction: p < 0.0001). Next to FUSP change, other statistically significant confounding factors/covariates also associated with glucose changes were gender, ethnicity, metabolic subgroup, and baseline glucose. These analyses indicate that delaying time to first void may have beneficial effects on reducing blood glucose in nocturia patients. These data are among the first to suggest that improving sleep may have salutary effects on a cardiometabolic measure. PMID:27003433

    Gordon, David M; Ash, Stephen R

    2009-01-01

    The purpose of this research project was to determine whether the glucose level of a blood plasma sample from a diabetic patient could be predicted by measuring the density and conductivity of ultrafiltrate of plasma created by a 30,000 m.w. cutoff membrane. Conductivity of the plasma filtrate measures electrolyte concentration and should correct density measurements for changes in electrolytes and water concentration. In vitro studies were performed measuring conductivity and density of solutions of varying glucose and sodium chloride concentrations. Plasma from seven hospitalized patients with diabetes was filtered across a 30,000 m.w. cutoff membrane. The filtrate density and conductivity were measured and correlated to glucose levels. In vitro studies confirmed the ability to predict glucose from density and conductivity measurements, in varying concentrations of glucose and saline. In plasma filtrate, the conductivity and density measurements of ultrafiltrate allowed estimation of glucose in some patients with diabetes but not others. The correlation coefficient for the combined patient data was 0.45 which was significant but only explained 20% of the variability in the glucose levels. Individually, the correlation was significant in only two of the seven patients with correlation coefficients of 0.79 and 0.88. The reasons for lack of correlation are not clear, and cannot be explained by generation of idiogenic osmoles, effects of alcohol dehydrogenase, water intake, etc. This combination of physical methods for glucose measurement is not a feasible approach to measuring glucose in plasma filtrate.

    Full Text Available In the present study we examined gross changes in the mass of whole adrenal glands and that of the adrenal cortex, as well as the serum corticosterone and glucose level of mature male Wistar rats subjected to three different treatments: animals subjected to chronic restraint-stress, animals injected with lithium (Li and chronically stressed rats treated with Li. Under all three conditions we observed hypertrophy of whole adrenals, as well as the adrenal cortices. Chronic restraint stress, solely or in combination with Li treatment, significantly elevated the corticosterone level, but did not change the blood glucose level. Animals treated only with Li exhibited an elevated serum corticosterone level and blood glucose level. The aim of our study was to investigate the modulation of the chronic stress-induced effect on the blood glucose level by lithium, as a possible mechanism of avoiding the damage caused by chronic stress. Our results showed that lithium is an agent of choice which may help to reduce stress-elevated corticosterone and replenish exhausted glucose storages in an organism.

    Type II diabetes mellitus (DM) increases risk for cognitive decline and is associated with brain atrophy in older demented and non-demented individuals. We investigated (1) the cross-sectional association between fasting blood glucose level and cortical thickness in a sample of largely middle-aged, cognitively normal adults, and (2) whether these associations were modified by genes associated with both lipid processing and dementia. To explore possible modifications by genetic status, we investigated the interaction between blood glucose levels and the apolipoprotein E (APOE) ε4 allele and the translocase of the outer mitochondrial membrane (TOMM) 40 '523 genotype on cortical thickness. Cortical thickness measures were based on mean thickness in a subset of a priori-selected brain regions hypothesized to be vulnerable to atrophy in Alzheimer's disease (AD) (i.e., 'AD vulnerable regions'). Participants included 233 cognitively normal subjects in the BIOCARD study who had a measure of fasting blood glucose and cortical thickness measures, quantified by magnetic resonance imaging (MRI) scans. After adjustment for age, sex, race, education, depression, and medical conditions, higher blood glucose was associated with thinner parahippocampal gyri (B=-0.002; 95% CI -0.004, -0.0004) and temporal pole (B=-0.002; 95% CI -0.004, -0.0001), as well as reduced average thickness over AD vulnerable regions (B=-0.001; 95% CI -0.002, -0.0001). There was no evidence for greater cortical thinning in ε4 carriers of the APOE gene or in APOE ε3/3 individuals carrying the TOMM40 VL/VL genotypes. When individuals with glucose levels in the diabetic range (≥126mg/dL), were excluded from the analysis, the associations between glucose levels and cortical thickness were no longer significant. These findings suggest that glucose levels in the diabetic range are associated with reduced cortical thickness in AD vulnerable regions as early as middle age. PMID:27206882

    The number of diabetics is rapidly growing every day in all parts of the world. By the year 2010, the number of patients suffering from diabetes had amounted to more than 230 million people, which is estimated as 3.5% of the whole world adult population [1]. According to expert forecasts, this number is projected to double by the year 2025, which is going to be 7% of whole Earth population. It was calculated that every 10 seconds someone in the world dies due to diabetes and its complications, which is 3 million people per year. The average life expectancy of children with diabetes is less than 28.3 years of onset. Diabetes is considered to be the fourth most common cause of death in industrialized countries. Vascular complications due to diabetes cause early disability and high mortality. Mortality from heart diseases and strokes is 2-3 times more likely for patients suffering from diabetes, whereas blindness, nephropathy and lower limbs gangrene happen respectively 10, 12-15 times, and almost 20 times more often for diabetics than general population. The number and strength of complications depend directly on the blood glucose level control quality. At the moment, the blood glucose level measurements are performed by glucometers [2,3]. This method requires that a patient makes a finger puncture for every measurement. About five punctures per day should be done for proper glucose monitoring, which is about 1,800 punctures per year. Besides, each measurement by glucometer requires a distinct test strip. Expenses for 1,800 test strips could be estimated as about 450 euros per year. It is also necessary to take into account that each puncture has a risk of blood poisoning. Using non-invasive techniques for glucose level control could reduce the amount of possible risky manipulations by 1800 per year. Moreover, it is worth mentioning that only eight of ten fingers are suitable for puncturing, and the constant skin damage which cannot be avoided is quite annoying for

    Background Some dominant bacterial divisions of the intestines have been linked to metabolic diseases such as overweight and diabetes. Objective A pilot study aimed to evaluate the relations between the culturable intestinal bacteria with body mass index (BMI) and some principal cellular and metabolic markers of blood in people older than 65. Design Altogether 38 generally healthy elderly people were recruited: ambulatory (n=19) and orthopedic surgery (n=19). Questionnaires on general health, anthropometric measurements, routine clinical and laboratory data, and quantitative composition of cultivable gut microbiota were performed. Results Blood glucose level was positively correlated with BMI (r=0.402; p=0.014). Higher blood glucose level had negative correlation with relative share of intestinal anaerobic bacteria such as bacteroides (r=−0.434; p=0.0076) and gram-positive anaerobic cocci (r=−0.364; p=0.027). In contrast, the relative share of bifidobacteria (r=0.383; p=0.019) and staphylococci (r=0.433; p=0.008) was positively correlated to blood glucose level. In elderly people, a higher blood glucose concentration was predicted by the reduction of the anaerobes’ proportion (adj. sex, age, and BMI R2=0.192, p=0.028) and that of Bacteroides sp. (adj. R2=0.309, p=0.016). Conclusion A tight interplay between increased BMI, level of blood glucose, and the reduced proportion of cultivable bacteroides is taking place in the gut microbiota of elderly people.

    AIM: Hyperglycemia commonly seen in liver transplantation (LT) has often been attributed to the dextrose in the storage solution of blood transfusion products. The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. METHODS: A retrospective study on 60 biliary pediatric patients and 16 adult patients undergoing LT was carried out. Transfused pediatric patients were included in Group Ⅰ (GI), those not transfused in Group Ⅱ (GⅡ). Twelve adult patients were not given transfusion and assigned to Group Ⅲ (GⅢ); whereas, four adult patients who received massive transfusion were assigned to Group Ⅳ (GⅣ). The blood glucose levels, volume of blood transfused, and the volume of crystalloid infused were recorded, compared and analyzed. RESULTS: Results showed that the changes in bloodglucose levels during LT for both non-transfused and minimally transfused pediatric groups and non-transfused and massively-transfused adult groups were almost the same. CONCLUSION: We conclude that blood transfusion does not cause significant changes in the blood glucose levels inthis study.

  14. Melatonin Signaling Controls the Daily Rhythm in Blood Glucose Levels Independent of Peripheral Clocks.

    Directory of Open Access Journals (Sweden)

    Sharon Owino

    Full Text Available Melatonin is rhythmically secreted by both the pineal gland and retina in a circadian fashion, with its peak synthesis occurring during the night. Once synthesized, melatonin exerts its effects by binding to two specific G-protein coupled receptors-melatonin receptor type 1(MT1 and melatonin receptor type 2(MT2. Recent studies suggest the involvement of MT1 and MT2 in the regulation of glucose homeostasis; however the ability of melatonin signaling to impart timing cues on glucose metabolism remains poorly understood. Here we report that the removal of MT1 or MT2 in mice abolishes the daily rhythm in blood glucose levels. Interestingly, removal of melatonin receptors produced small effects on the rhythmic expression patterns of clock genes within skeletal muscle, liver, and adipose tissue. Taken together, our data suggest that the loss of the daily rhythm in blood glucose observed in MT1(-/- and MT2(-/- mice does not occur as a consequence of 'disrupted' clocks within insulin sensitive tissues. Finally our results highlight a diurnal contribution of melatonin receptor signaling in the daily regulation of blood glucose levels.

  15. The effect of food with different glycaemic index on the blood glucose level

    Full Text Available Blood glucose levels are affected by many factors including the type of foods consumed, processing technology and cooking method. Hormone insulin lowers blood glucose to its constant level, while glucagon, growth hormone, adrenalin and glucocorticoids have the opposite effect. High steepness of the blood glucose level rise after meals may be unfavourable for the organism. Sugars are transferred into the blood at different speeds according to the type of food. Therefore the aim of this study was to confirm experimentally the effect of food on blood glucose levels in men and women of different ages. Two types of low, medium and high-glycaemic index (GI foods were given to 4 men and 4 women of different age (from 35 to 65 years. All volunteers were healthy, slightly overweight, and without any regular sporting activity. None of them had any idea about their daily carbohydrates consumption and what the term glycaemic index meant. The volunteers came to the GI determination fasted in the morning. Their rise in blood glucose level was monitored by glucometer before the meal and after 1 and 2 hours of the consumption of baked potatoes (GI 85, white bread bun (GI 70, boiled potatoes (GI 64, rye bread (GI 62, potato dumplings (GI 52 and white cooked spaghetti (GI 41. Fasting blood sugar levels of volunteers highly depended on their age (p <0.0001 and gender (p <0.0001. The blood glucose values increased with age and were higher in men than in women. Significant influence of food GI on blood glucose levels in both men and women in all the age categories was observed (p <0.0001. An interaction between age and gender was also statistically highly significant (p <0.0001. One hour after consuming food the blood glucose values were significantly different from the values of fasting (p = 0.0035. The differences of these values did not depend on the age (p = 0.0574 and sex (p = 0.8256 of volunteers, but there was a significant difference on the GI value of food

    2014-01-01

    The paper presents an analytical model to estimate blood glucose level from measurements made non-invasively and in real time by an antenna strapped to a patient's wrist. Some promising success has been shown by the RIT ETA Lab research group that an antenna's resonant frequency can track, in real time, changes in glucose concentration. Based on an in-vitro study of blood samples of diabetic patients, the paper presents a modified Cole-Cole model that incorporates a factor to represent the change in glucose level. A calibration technique using the input impedance technique is discussed and the results show a good estimation as compared to the glucose meter readings. An alternate calibration methodology has been developed that is based on the shift in the antenna resonant frequency using an equivalent circuit model containing a shunt capacitor to represent the shift in resonant frequency with changing glucose levels. Work under progress is the optimization of the technique with a larger sample of patients.

  17. Relationship of endothelial nitric oxide synthase gene polymorphism with blood pressure,lipid profile and blood glucose level

    To study the relationship of the polymorphism of endothelial nitric oxide synthase(eNOS)gene and blood pressure,lipid profiles and blood glucose level.By using PCR-RFLP,the eNOS Glu298Asp gene polymorphism was detected in 184 patients with essential hypertension and 196 matched healthy individuals with normal blood pressure.Taking into account eNOS Glu298Asp polymorphisms,the relationship of blood pressure with triglycerides(TG),total cholesterol(TC),high density lipoprotein(HDL),low density lipoprotein(LDL)and blood glucose level was analyzed.The distribution of eNOS Glu298Asp polymorphism had no significant difference between different blood pressure groups and gender groups,but there was a significant difference between different age groups,diastolic blood pressure groups or BMI groups(P<0.05).Asp/Asp genotype significantly increased the risk of hypertension in individuals with serum TC above 5.4 mmol/L(P=0.03,OR=2.65).eNOSGlu298Asp polymorphism and serum lipid could synergistically modulate the blood pressure,eNOS Asp/Asp genotype could significantly increase the risk of hypertension in individuals with serum TC over 5.4 mmol/L,eNOS Glu298Asp in combination with serum TC could be used to predict the risk of hypertension.

  18. Clinical significance of determination of serum leptin, insulin levels and blood sugar in pregnant women with glucose metabolism disturbances

    International Nuclear Information System (INIS)

    Objective: To investigate the changes of serum leptin, insulin levels and blood sugar contents in pregnant women with gestational glucose metabolism disturbances. Methods: Fasting and 3h after oral 50g glucose serum levels of leptin were measured with RIA in 36 pregnant women with glucose metabolism disturbances (gestational diabetes mellitus or gestational impaired glucose tolerance) and 34 controls. Also, fasting serum insulin levels (with CLIA) and blood sugar contents 1h after oral 50 glucose (with glucose oxidase method) were determined in all these subjects. Results: 1. Serum levels of leptin in pregnant women with glucose metabolism disturbances were 14.9 ± 4.3 μg/L (vs controls 9.8 ± 1.7 μg/L, P<0.01). 2. The serum levels of insulin and 1 h post - 50g glucose blood sugar contents in pregnant women with glucose metabolism disturbances were 12.9±4.3mU/L and 11.0±1.4mmol/L respectively, which were both significantly positively correlated with the serum leptin levels (r=0.835, r=0.758 respectively) (vs levels in controls: 8.45±3.0mU/L and 7.84±1.3mmol/L). Conclusion: Elevation of fasting serum levels of leptin was demonstrated in pregnant women with glucose metabolism disturbances and the level of leptin was positively correlated with that of insulin and blood sugar.

    2016-01-01

    Background: Diabetes mellitus is a metabolic disorder that results in hyperglycemia. According to the statistics of the International Diabetes Federation (IDF), this problem has a fast growing prevalence and, unfortunately, leaves permanent complications on different body systems. For this reasons, nowadays attentions has been paid to the traditional medicine such as Okra (Abelmoscus esculentus). The aim of this study was the evaluation of the effect of Okra (Abelmoscus esculentus) on blood levels of glucose in diabetes. Methods: This is a review article, which was obtained by a search in databases such as PubMed, Google Scholar, and Magiran by using keywords such as diabetes, Okra, and hypoglycemic effect. Results: Various studies on Okra (Abelmoscus esculentus) showed that Abelmoscus esculentus (AE)/Okra extract has a hypoglycemic effect that helps decrease blood glucose level. Its properties can be a useful remedy to manage diabetes mellitus. In addition, it leads to inhibition of cholesterol absorption and subsequently decreases the level of lipid and fat in the blood. The results of an investigation on diabetic mice by using this material has shown the same effect and confirmed this conclusion. Conclusion: Based on the positive effects of Okra on reducing blood sugar level, the widespread use of this plant is recommended. Clearly, further research is required.

  14. Low blood glucose levels and other complications during growth hormone supplementation in sepsis

    Directory of Open Access Journals (Sweden)

    Faintuch Joel

    1999-01-01

    Full Text Available Blood glucose levels in the high normal range or even moderate hyperglycemia is the expected profile in septic postoperative patients receiving high-calorie enteral alimentation. The addition of growth hormone as an anabolic agent should additionally reinforce this tendency. In a cancer patient undergoing partial gastrectomy with lymphadenectomy and suffering from postoperative subphrenic abscess and prolonged sepsis, tube feeding (38.3 kcal/kg/day and growth hormone (0.17 IU/kg/day were simultaneously administered for 25 days. Blood glucose levels were in the lower limits of the normal range before growth hormone introduction, and continued with a similar tendency during most of the therapeutic period. Two additional complications, namely heart arrest and peripheral edema, were documented during the same period. It is concluded that sepsis was the most likely mechanism for low glucose values, and that high-calorie enteral diet and growth hormone supplementation did not prevent that result. It is uncertain whether heart arrest was due to the drug, but its association with peripheral edema is well documented in clinical series.

    Blood glucose (BG) is usually measured after a caloric restriction of at least 8 h; however evidence-based recommendations for the duration of a fasting status are missing. Here we analyze the effect of fasting duration on levels of BG to determine the minimal fasting duration to achieve comparable BG levels to conventional fasting measurements. We used data of a cross-sectional study on primary care patients, performed in October 2005. We included 28,024 individuals (age-range 18-99 years; 63% women) without known diabetes mellitus and without missing data for BG and fasting status. We computed general linear models, adjusting for age, sex, time of blood withdrawal, systolic blood pressure, waist circumference, total- and HDL-cholesterol, physical activity, smoking, intake of beta-blocker and alcohol. We tested the intra-individual variability with respect to fasting status. Overall, the mean BG differed only slightly between individuals fasting ≥ 8 h and those fasting fasting differences of BG diminished in men to -0.08 mmol/L (95%-CI: -0.15; -0.01 mmol/L), in women to -0.07 mmol/L (-0.12; -0.03 mmol/L) compared to individuals fasting ≥ 8 h. Noteworthy, age, time of day of blood withdrawal, physical activity, and intake of hard liquor influenced BG levels considerably. Our data challenge the necessity for a fasting duration of ≥ 8 h when measuring blood glucose, suggesting a random sampling or a fasting duration of 3 h as sufficient. Rather, our study indicates that essentially more effort on the assessment of additional external/internal factors on BG levels is necessary. PMID:21822717

    This study investigated whether mad honey affects blood glucose and lipid levels in experimental animals. It was found that mad honey caused significant decreases in blood glucose and lipid levels in animals with streptozocin-induced diabetes mellitus (n = 10) and controls (n = 10). These decreases may be due to grayanotoxins in the mad honey causing the islets of Langerhans in the pancreas to secrete insulin by stimulating the parasympathetic nervous system or M2-muscarinic receptors.

    International Nuclear Information System (INIS)

    Objective: To evaluate the glucose lowering effect of 50% ethanol extract of Syzygium aromaticum in comparison with that of standard insulin in streptozotocin induced diabetic rats. Study Design: Randomized control trial. Place and Duration of Study: National Institute of Health Islamabad. Jul 2011- Dec 2011 Material and Methods: It was carried out on 48 adult rats of Sprague dawley specie. Rats were equally divided into 6 groups (I-VI). Group - I served as control. Diabetes was induced by giving single intraperitoneal injection of STZ in Group II to VI. Group-II served as diabetic control, while groups III, IV, V and VI served as experimental groups. Group III, IV and V rats received 50% ethanol extract of Syzygium aromaticum at a dose of 250, 500 and 750 mg/kg body weight respectively for sixty days. Group VI (standard) received humulin insulin 70/30 at dose of 0.6 units<-kg body weight subcutaneously bid for sixty days. Fasting blood samples were taken at zero day, 15 day, 30 day and 60 day after giving injection STZ. Although Syzygium aromaticum with the doses of 250, 500 and 750 mg/kg body weight and insulin reduced the level of glucose in rats but on comparison Syzygium aromaticum 750 mg=kg dose reduced glucose more effectively than 250 and 500 mg/kg dose. While in group III, IV subjects, blood glucose levels remained above normal level. In group VI receiving insulin the level of this parameter remained almost closer to group IV rats. On studying the weight of the animals after receiving STZ there was initial reduction in the weight of all the experimental groups but after receiving the extract of plant improvement was seen and the weight of group V getting 750 mg=kg/body weight of Syzygium aromaticum became almost closer to the weight of control group. Conclusion: Syzygium aromaticum extract has glucose lowering effect in STZ induced diabetic rats and this effect is dose related and the dose of 750 mg/kg body weight has produced maximum effect.

    Full Text Available Rajib K Bhattacharya, Jonathan D Mahnken, Sally K RiglerUniversity of Kansas School of Medicine, Kansas City, KS, USABackground: Community-acquired pneumonia (CAP is a common cause of morbidity and mortality in older adults. Although diabetes mellitus is a risk factor for pneumonia, the clinical impact of blood glucose level at the time of admission is not clear. Our goal was to examine the association between admission hyperglycemia and subsequent mortality, length of stay, and readmission outcomes in older adults with CAP.Methods: A retrospective observational study was conducted using hospital data for community-acquired pneumonia admissions in 857 persons from January 1, 2008 to December 31, 2010. We examined the effects of admission glucose level on mortality, length of stay, and 30 day readmission, adjusted for demographic factors and comorbidity.Results: The mean age of the sample was 64 years, and 51% of the subjects were female. Inpatient mortality occurred in 4.6% and the median length of stay was 5 days (interquartile range 3–9 days. Readmission within 30 days occurred in 17%. We found little impact of first glucose measures on in-hospital mortality (P = 0.94, length of stay (P = 0.95, and 30-day readmission (P = 0.56. Subjects 65 years and older trended towards higher in-hospital mortality. Older age, cancer, heart failure, and cirrhosis were associated with adverse outcomes.Conclusion: Glucose level upon admission for community-acquired pneumonia was not associated with adverse outcomes within 30 days in older adults.Keywords: community-acquired pneumonia, hyperglycemia, readmission rates, hospital mortality

    Background Previous studies reported increased risk of cardiac events in subjects with fasting blood glucose (FBG) levels lower than the diagnostic threshold of diabetes mellitus. However, whether increased cardiac events in those with upper normal FBG is secondary to the shift of their cardiac sympathovagal balance towards sympathetic predominance is unknown. Aims To assess the association between FBG levels and cardiac autonomic modulation (CAM) in euglycaemic healthy subjects based on heart rate variability (HRV) derived indices. Subjects and Methods The study enrolled 42 healthy young adults. Following sociodemographic and clinical assessment, blood samples were collected to measure FBG levels. Five minutes ECG recordings were performed to all participants to obtain frequency domain HRV measurements, namely the natural logarithm (Ln) of total power (LnTP), very low frequency (LnVLF), low frequency (LnLF) and high frequency (LnHF), low frequency/ high frequency ratio (LnLF/HF), normalized low frequency (LF Norm) and high frequency (HF Norm). Results FBG levels correlated positively with LnHF (r = 0.33, P = 0.031) and HF Norm (r = 0.35, P = 0.025) and negatively with LF Norm (r = -0.35, P = 0.025) and LnLF/HF (r = -0.33, P = 0.035). LnHF and HF Norm were significantly decreased in subjects with the lower (4.00 (1.34) ms2/Hz and 33.12 (11.94) n.u) compared to those with the upper FBG quartile (5.64 (1.63) ms2/Hz and 49.43 (17.73) n.u, P = 0.013 and 0.032 respectively). LF Norm and LnLF/HF were significantly increased in subjects with the lower (66.88 (11.94) n.u and 0.73 (0.53)) compared to those with the higher FBG quartile (50.58 (17.83) n.u and 0.03 (0.79), P = 0.032 and 0.038 respectively). Conclusion The present study is the first to demonstrate that rise of blood glucose concentration, within physiological range, is associated with higher parasympathetic, but lower sympathetic CAM. Further researches are needed to set out the glycemic threshold beyond which

    The effects of Cnidoscolus aconitifolius (CA) leaf extract and chlorpropamide on blood glucose and insulin levels in the inbred type 2 diabetic mice are reported. After treatment with CA, the glucose levels were measured at 0 and 2-hour intervals in experimental groups and controls. Group I received no treatment and served as control; Group II was the reference and it received chlorpropamide; Groups I-III were moderately diabetic, 100-300 mg/dL blood glucose levels while Group IV were severely diabetic (> 300 mg/dL). Groups III and IV received CA and served as test groups. There was no significant difference between the blood glucose levels at 0 and 2 hours for the control group, (P>0.23) but there were statistically significant differences for Group II (P<0.0002); Group III (P<0.002) and Group IV (P<0.0001). For moderately diabetic mice, CA and chlorpropamide decreased the glucose levels by 25.6% and 16.3% respectively while for the severely diabetic mice CA decreased the blood glucose by 43.7%. It is proposed that CA has an insulinogenic property that possibly stimulated dormant beta-cells to secrete insulin. The histopathology of several organs in the treated animals was found to differ from the expected. The islets of Langerhans for example were found to be preserved in the time frame examined. Also the liver and kidney were found to display milder pathology in the treated groups. PMID:17531147

  11. Blood glucose in acute stroke

    2009-01-01

    Blood glucose is often elevated in acute stroke, and higher admission glucose levels are associated with larger lesions, greater mortality and poorer functional outcome. In patients treated with thrombolysis, hyperglycemia is associated with an increased risk of hemorrhagic transformation...... of infarcts. For a number of years, tight glycemic control has been regarded as beneficial in critically illness, but recent research has been unable to support this notion. The only completed randomized study on glucose-lowering therapy in stroke has failed to demonstrate effect, and concerns relating...... to the risk of inducing potentially harmful hypoglycemia has been raised. Still, basic and observational research is overwhelmingly in support of a causal relationship between blood glucose and stroke outcome and further research on glucose-lowering therapy in acute stroke is highly warranted....

  12. A tripeptide Diapin effectively lowers blood glucose levels in male type 2 diabetes mice by increasing blood levels of insulin and GLP-1.

    Directory of Open Access Journals (Sweden)

    Jifeng Zhang

    Full Text Available The prevalence of type 2 diabetes (T2D is rapidly increasing worldwide. Effective therapies, such as insulin and Glucagon-like peptide-1 (GLP-1, require injections, which are costly and result in less patient compliance. Here, we report the identification of a tripeptide with significant potential to treat T2D. The peptide, referred to as Diapin, is comprised of three natural L-amino acids, GlyGlyLeu. Glucose tolerance tests showed that oral administration of Diapin effectively lowered blood glucose after oral glucose loading in both normal C57BL/6J mice and T2D mouse models, including KKay, db/db, ob/ob mice, and high fat diet-induced obesity/T2D mice. In addition, Diapin treatment significantly reduced casual blood glucose in KKay diabetic mice in a time-dependent manner without causing hypoglycemia. Furthermore, we found that plasma GLP-1 and insulin levels in diabetic models were significantly increased with Diapin treatment compared to that in the controls. In summary, our findings establish that a peptide with minimum of three amino acids can improve glucose homeostasis and Diapin shows promise as a novel pharmaceutical agent to treat patients with T2D through its dual effects on GLP-1 and insulin secretion.

  13. Molecular Weight Dependent Glucose Lowering Effect of Low Molecular Weight Chitosan Oligosaccharide (GO2KA1 on Postprandial Blood Glucose Level in SD Rats Model

    Full Text Available This research investigated the effect of enzymatically digested low molecular weight (MW chitosan oligosaccharide on type 2 diabetes prevention. Three different chitosan oligosaccharide samples with varying MW were evaluated in vitro for inhibition of rat small intestinal α-glucosidase and porcine pancreatic α-amylase (GO2KA1; 10,000 Da. The in vitro results showed that all tested samples had similar rat α-glucosidase inhibitory and porcine α-amylase inhibitory activity. Based on these observations, we decided to further investigate the effect of all three samples at a dose of 0.1 g/kg, on reducing postprandial blood glucose levels in Sprague-Dawley (SD rat model after sucrose loading test. In the animal trial, all tested samples had postprandial blood glucose reduction effect, when compared to control, however GO2KA1 supplementation had the strongest effect. The glucose peak (Cmax for GO2KA1 and control was 152 mg/dL and 193 mg/dL, respectively. The area under the blood glucose-time curve (AUC for GO2KA1 and control was 262 h mg/dL and 305 h mg/dL, respectively. Furthermore, the time of peak plasma concentration of blood glucose (Tmax for GO2KA1 was significantly delayed (0.9 h compared to control (0.5 h. These results suggest that GO2KA1 could have a beneficial effect for blood glucose management relevant to diabetes prevention in normal and pre-diabetic individuals. The suggested mechanism of action is via inhibition of the carbohydrate hydrolysis enzyme α-glucosidase and since GO2KA1 (MW < 1000 Da had higher in vivo effect, we hypothesize that it is more readily absorbed and might exert further biological effect once it is absorbed in the blood stream, relevant to blood glucose management.

    Full Text Available O Peter AdamsFaculty of Medical Sciences, the University of the West Indies, Cave Hill Campus, St Michael, BarbadosBackground: Moderate-intensity exercise improves blood glucose (BG, but most people fail to achieve the required exercise volume. High-intensity exercise (HIE protocols vary. Maximal cycle ergometer sprint interval training typically requires only 2.5 minutes of HIE and a total training time commitment (including rest and warm up of 25 minutes per session. The effect of brief high-intensity exercise on blood glucose levels of people with and without diabetes is reviewed.Methods: HIE (≥80% maximal oxygen uptake, VO2max studies with ≤15 minutes HIE per session were reviewed.Results: Six studies of nondiabetics (51 males, 14 females requiring 7.5 to 20 minutes/week of HIE are reviewed. Two weeks of sprint interval training increased insulin sensitivity up to 3 days postintervention. Twelve weeks near maximal interval running (total exercise time 40 minutes/week improved BG to a similar extent as running at 65% VO2max for 150 minutes/week. Eight studies of diabetics (41 type 1 and 22 type 2 subjects were reviewed. Six were of a single exercise session with 44 seconds to 13 minutes of HIE, and the others were 2 and 7 weeks duration with 20 and 2 minutes/week HIE, respectively. With type 1 and 2 diabetes, BG was generally higher during and up to 2 hours after HIE compared to controls. With type 1 diabetics, BG decreased from midnight to 6 AM following HIE the previous morning. With type 2 diabetes, a single session improved postprandial BG for 24 hours, while a 2-week program reduced the average BG by 13% at 48 to 72 hours after exercise and also increased GLUT4 by 369%.Conclusion: Very brief HIE improves BG 1 to 3 days postexercise in both diabetics and nondiabetics. HIE is unlikely to cause hypoglycemia during and immediately after exercise. Larger and longer randomized studies are needed to determine the safety, acceptability, long

    Full Text Available Introduction: Hyperlipidemia and diabetes are common risk factors for ischemic heart disease, which is the main cause of mortality in diabetic patients. Strict control of blood glucose and other risk factors in diabetics has led to prevention of complications. Garlic has received particular attention for control of blood glucose and decrease in blood lipid levels. At present, several studies have been carried out in order to prove advantages of garlic. Methods: In this study, effects of garsin (a derivative of garlic present in our country on serum lipids and blood glucose levels in diabetes mellitus type 2 patients was observed. Forty-five type 2 diabetics who had hyperlipidemia were selected. These patients were kept on treatment with 3 tablets of Garsin / day for 4 weeks. Serum lipids and blood glucose levels were measured prior to and at the end of treatment. Results: Relationship between sex and response to treatment in this study was meaningful, such that Gsarsin led to decrease in LDL-C and increase in HDL in females. Conclusion: Therefore, Garsin can be used as an adjunct to treatment in diabetes type 2 patients with hyperlipidemia.

    In the present work we studied the effects of four alcoholic beverages on blood alcohol levels, plasma insulin concentrations and plasma glucose concentrations in men and women. The volunteers were healthy non-smokers and they were divided according to sex into two groups of ten individuals. The alcoholic beverages used in the study were beer, red wine, whisky and "cachaça". In men, ingestion of the distilled drinks promoted a spike in blood alcohol levels more quickly than ingestion of the fermented drinks. In women, beer promoted the lowest blood alcohol levels over the 6h of the experiment. Whisky promoted highest blood alcohol levels in both sexes. The ingestion of wine promoted a significant difference in relation to the blood alcohol concentration (BAC) as a function of gender. The ingestion of cachaça by women produced BAC levels significantly smaller than those obtained for wine.

    2015-07-01

    For blood glucose level measurement of dialysis machines, we proposed AAA-battery-size ATR (Attenuated total reflection) Fourier spectroscopy in middle infrared light region. The proposed one-shot Fourier spectroscopic imaging is a near-common path and spatial phase-shift interferometer with high time resolution. Because numerous number of spectral data that is 60 (= camera frame rare e.g. 60[Hz]) multiplied by pixel number could be obtained in 1[sec.], statistical-averaging improvement realize high-accurate spectral measurement. We evaluated the quantitative accuracy of our proposed method for measuring glucose concentration in near-infrared light region with liquid cells. We confirmed that absorbance at 1600[nm] had high correlations with glucose concentrations (correlation coefficient: 0.92). But to measure whole-blood, complex light phenomenon caused from red blood cells, that is scattering and multiple reflection or so, deteriorate spectral data. Thus, we also proposed the ultrasound-assisted spectroscopic imaging that traps particles at standing-wave node. Thus, if ATR prism is oscillated mechanically, anti-node area is generated around evanescent light field on prism surface. By elimination complex light phenomenon of red blood cells, glucose concentration in whole-blood will be quantify with high accuracy. In this report, we successfully trapped red blood cells in normal saline solution with ultrasonic standing wave (frequency: 2[MHz]).

    Background Hyperglycemia in brain and spinal cord could aggravate neurologic impairment. Recent studies showed that L-lysine monohydrochlonde (LMH) could increase the insulin secretion and regulate the blood glucose level. The aim of the present study was to investigate the effects of LMH on pancreatic islet B cells, the levels of endogenous insulin and blood glucose in spinal cord injured rats.Methods Forty male Wistar rats were divided into four groups, namely, normal control group, model group, high-dose LMH group (621.5 mg/kg equal to LMH 1/8 LD50), and low-dose LMH group (310.8 mg/kg equal to LMH 1/16 LD50). The model of spinal cord injured rat was established by hemi-transection at the lower right thoracic spinal cord. LMH was administered via intraperitoneal injection once spinal cord injury was produced in rats. All rats were sacrificed 48 hours after spinal cord injured. The effects of LMH on pancreatic islet B cells, the content of endogenous insulin, end the level of blood glucose were observed with immunohistochemical method, radioimmunoassay method, end biochemical analyzer, respectively. Results The insulin immunohistochemical intensities of islet B cells were significantly weaker in model group then those in normal control group (P 0.05). Conclusion LMH, but dose-dependent, might participate in the regulation of pancreatic islet B cells, and then reduce the blood glucose levels in the spinal cord injured rats.

    Machine learning techniques such as logistic regression (LR), support vector machine (SVM) and artificial neural network (ANN) were used to detect fasting blood glucose levels (FBGL) in a mixed population of healthy and diseased individuals in an Indian population. The occurrence of elevated FBGL was estimated in a non-invasive manner from the status of an individual's salivary electrochemical parameters such as pH, redox potential, conductivity and concentration of sodium, potassium and calcium ions. The samples were obtained from 175 randomly selected volunteers comprising half healthy and half diabetic patients. The models were trained using 70 % of the total data, and tested upon the remaining set. For each algorithm, data points were cross-validated by randomly shuffling them three times prior to implementing the model. The performance of the machine learning technique was reported in terms of four statistically significant parameters-accuracy, precision, sensitivity and F1 score. SVM using RBF kernel showed the best performance for classifying high FBGLs with approximately 85 % accuracy, 84 % precision, 85 % sensitivity and 85 % F1 score. This study has been approved by the ethical committee of All India Institute of Medical Sciences, New Delhi, India with the reference number: IEC/NP-278/01-08-2014, RP-29/2014. PMID:27350930

    A mid-infrared attenuated total reflection (ATR) spectroscopy system employing hollow optical fibers and a trapezoidal multi-reflection ATR prism has been developed to measure blood glucose levels. Using a multi-reflection prism brought about higher sensitivity, and the flat and wide contact surface of the prism resulted in higher measurement reproducibility. An analysis of in vivo measurements of human inner lip mucosa revealed clear signatures of glucose in the difference spectra between ones taken during the fasting state and ones taken after ingestion of glucose solutions. A calibration plot based on the absorption peak at 1155 cm(-1) that originates from the pyranose ring structure of glucose gave measurement errors less than 20%. PMID:26977373

Objective: To evaluate the bio-enhancing effect of piperine with metformin in lowering blood glucose levels in alloxan-induced diabetic mice. Materials and Methods: Piperine was isolated from an extract of fruits of P. nigrum. Alloxan-induced (150 mg/kg intraperitoneal diabetic mice were divided into four groups. Group I (control 2% gum acacia 2 g/100 mL, Group II (metformin 250 mg/kg, Group III (metformin and piperine 250 mg/kg + 10 mg/kg, and Group IV (metformin and piperine 125 mg/kg + 10 mg/kg. All the drugs were administered orally once daily for 28 days. Blood glucose levels were estimated at day 0, day 14, and end of the study (day 28. Results: The combination of piperine with therapeutic dose of metformin (10 mg/kg + 250 mg/kg showed significantly more lowering of blood glucose level as compared to metformin alone on both 14 th and 28 th day (P < 0.05. Piperine in combination with sub-therapeutic dose of metformin (10 mg/kg + 125 mg/kg showed significantly more lowering of blood glucose as compared to control group and also showed greater lowering of blood glucose as compared to metformin (250 mg/kg alone. Conclusion: Piperine has the potential to be used as a bio-enhancing agent in combination with metformin which can help reduce the dose of metformin and its adverse effects.

    Full Text Available ABSTRACTPurpose:To investigate the influence of the blood glucose level on the development of retinopathy of prematurity (ROP in extremely premature infants.Methods:Sixty-four premature infants with a gestational age of less than 30 weeks and a birth weight of less than 1500 g were included in the study. Children without ROP were allocated to Group 1 (n=14, gestational age 28.6 ± 1.4 weeks, birth weight 1162 ± 322 g, and children with spontaneous regression of ROP were allocated to Group 2 (n=32, gestational age 26.5 ± 1.2 weeks, birth weight 905 ± 224 g. Children with progressive ROP who underwent laser treatment were included in Group 3 (n=18, gestational age 25.4 ± 0.7 weeks, birth weight 763 ± 138 g. The glucose level in the capillary blood of the premature infants was monitored daily during the first 3 weeks of life. A complete ophthalmological screening was performed from the age of 1 month. The nonparametric signed-rank Wilcoxon-Mann-Whitney test was used for statistical analysis.Results:The mean blood glucose level was 7.43 ± 2.6 mmol/L in Group 1, 7.8 ± 2.7 mmol/L in Group 2, and 6.7 ± 2.6 mmol/L in Group 3. There were no significant differences in the blood glucose levels between children with and without ROP, and also between children with spontaneously regressing ROP and progressive ROP (p>0.05. Additionally, there were no significant differences in the blood glucose levels measured at the first, second, and third weeks of life (p>0.05.Conclusion:The blood glucose level is not related to the development of ROP nor with its progression or regression. The glycemic level cannot be considered as a risk factor for ROP, but reflects the severity of newborns’ somatic condition and morphofunctional immaturity.

    The levels of blood glucose (BG) in humans tend to increase with age deviating from the norm specified for the young adults. Such elevation is often considered as a factor contributing to an increase in risks of disease and death. The proper use of intervention strategies coping with or preventing consequences of BG elevation requires understanding the roles of external forces and intrinsic senescence in this process. To address these issues, we performed analyses of longitudinal data on BG c...

    Full Text Available Abstract Background Although a device is needed to continuously measure blood glucose levels within an intensive care setting, and several large-scale prospective studies have shown that patients might benefit from intensive insulin, potassium, or glucose therapy during intensive care, no devices are currently available to continuously assess blood glucose levels in critically ill patients. We conceived the study described here to evaluate the clinical use of the Continuous Glucose Monitor (CGM performed via a central vein, and to determine the impact of phenomena, such as drift and shift, on the agreement between the CGM and a RAPIDLab® 1265 blood gas analyser (BGA. Methods/design In the CONTinuous ASSessment of blood GLUcose (CONTASSGLU study, up to 130 patients under intensive care will be fitted with the CGM, an ex vivo device that continuously measures blood glucose and lactate levels. Readings from the device taken 8 h after initial placement and calibration will be compared with values measured by a BGA. For this study, we chose the BGA as it is an established standard point-of-care device, instead of the devices used in certified central laboratories. Nevertheless, we will also independently compare the results from the point-of-care BGA with those determined by a central laboratory-based device. Blood samples will be collected from each patient from the same site in which the CGM will measure blood glucose. Consequently, each participant will serve as their own control, and no randomisation is necessary. The 95% limits of agreement and the corresponding confidence intervals will be calculated and compared with a prespecified clinically acceptable relative difference of 20%. Discussion Several attempts have been made to develop a device to continuously measure blood glucose levels within an intensive care setting or to use the devices that were originally designed for diabetes management, as several of these devices are already

    Increased, non-pathological FDG uptake in myocardium, stomach and bowel is frequently observed while performing clinical positron emission tomography (PET) studies. This ''physiological'' increased FDG uptake is not related to (oncological) disease and is unwanted since it may interfere with correct image reading. We evaluated the role of several patient-related factors that may have an influence on this phenomenon. One hundred and seventy-five non-diabetic patients with malignant diseases, referred to our department for routine whole-body FDG-PET, were retrospectively evaluated. Age, blood glucose levels and duration of the fasting period were recorded. FDG uptake in myocardium, bowel and stomach was visually graded. Statistical analysis showed that increased FDG uptake in myocardium, bowel and stomach was not significantly correlated to blood glucose level, age or duration of fasting. Most patients who underwent repeated PET scans (92 scans in 25 patients), showed no or minor changes in uptake in bowel and stomach on the consecutive scans, while myocardial uptake was more variable. Age, fasting period and blood glucose levels did not influence physiological uptake. However, there seemed to be a patient-specific pattern for stomach and bowel uptake. (orig.)

    Bats have an unusually large volume of endocrine tissue, with a large population of beta cells, and an elevated sensitivity to glucose and insulin. This makes them excellent animal models for studying diabetes mellitus. We evaluated bats as models for diabetes in terms of lifestyle and genetic factors. For lifestyle factors, we generated data sets of 149 body mass index (BMI) and 860 forearm mass index (FMI) measurements for different species of bats. Both showed negative inter-species correlations with blood glucose levels in sixteen bats examined. The negative inter-species correlations may reflect adaptation of a small insectivorous ancestor to a larger frugivore. We identified an 11 bp deletion in the proximal promoter of SLC2A2 that we predicted would disrupt binding sites for the transcription repressor ZNF354C. In frugivorous bats this could explain the relatively high expression of this gene, resulting in a better capacity to absorb glucose and decrease blood glucose levels. PMID:27439361

  20. Effect of blood glucose levels on image quality in 18F fluorodeoxyglucose scanning - a case report

    International Nuclear Information System (INIS)

    Full text: In December last year, a 71-year-old gentleman presented to the Nuclear Medicine Department at St Vincent's Hospital, Sydney for an FDG coincidence detection positron emission scan. The patient had cancer of the lung with a large lesion in the left upper lobe and a small lesion in the right middle lobe. On initial investigation, this patient had a blood sugar level of 17mmol/L which was eventually reduced to 6.7mmol/L just prior to scanning. The patient was then asked to return to be rescanned without his blood sugar levels being adjusted. Just prior to his second scan, his blood sugar level was 15.4mmollL. The aim of the initial scan being repeated was to see just how important a role blood sugar levels play in the quality of a Co Pet scan. The first scan showed excellent image quality while the repeated scan showed markedly inferior image quality due to unwanted soft tissue FDG uptake. In conclusion, blood sugar levels play a significant role in output image quality in FDG coincidence detection positron emission scanning.

    Full Text Available Introduction: Several studies have evaluated the association of admission blood glucose levels and short and long term mortality after myocardial infarction and have had different results. The aim of this study was evaluation of association between admission blood glucose levels and in-hospital and one year mortality in non-diabetic patients with AMI. Methods: In this study, demographic, clinical and Para clinical data of 120 non-diabetic patients with AMI on admission was collected and analyzed. The patients were followed for one year. Blood glucose level ≥ 140 mg/dl was defined as hyperglycemia. Results: 78% of patients were men. The mean age and admission blood glucose level was 63+13 years and 146+76mg/dl, respectively. Death due to cardio vascular causes was seen in 20% of patients in hospital and 9.8% during the one year follow up. The mean admission blood glucose level in patients who died in hospital was significantly more than live patients and also had an influence on the in-hospital outcome. Every 100mg/dl increase in blood glucose level was associated with 11% increase in in-hospital mortality risk in non-diabetic patients. Conclusion: Our results demonstrate that admission blood glucose level is a good marker for diagnosing patients with worse prognosis after AMI. We suggest that later studies should focus on optimal control of hyperglycemia with insulin in patients with AMI.

  2. Quantitative classification of HbA1C and blood glucose level for diabetes diagnosis using neural networks

    International Nuclear Information System (INIS)

    In this study, artificial neural network structures were used for the quantitative classification of Haemoglobin A1C and blood glucose level for diabetes diagnosis as a non-invasive measurement technique. The neural network structures make inferences from the relationship between the palm perspiration and blood data values. For this purpose, feed forward multilayer, Elman, and radial basis neural network structures were used. The quartz crystal microbalance type and humidity sensors were used for the detection of palm perspiration rates. Total 297 volunteer's data is used in this study. Three quarters of the data was used to train the neural networks. The remaining data were used as test data. The best results for the quantitative classification were obtained from the feed forward NN structure for the detection of the glucose and HbA1C level quantities. And, the performances of all neural networks for the HbA1C value were better than the performances of these neural networks for the glucose level.

    The serum glucose level is regulated within a narrow range by multiple factors under physiological conditions, but is greatly modified in the death process and after death. The present study comprehensively investigated glucose levels in blood and body fluids, including pericardial fluid (PCF), cerebrospinal fluid (CSF) and vitreous humor, reviewing forensic autopsy cases (n=672). Right heart blood glucose level was often higher than at other sites, and the CSF glucose level was the lowest, showing greater dissociation in acute/subacute death cases. The glucose level was higher in the diabetic (high HbA1c) than in the non-diabetic (low HbA1c) group at each site (pdeath due to ischemic heart disease. Fatal methamphetamine (MA) abuse, sepsis, malnutrition (starvation) and hypoglycemia due to antidiabetics showed markedly lower blood glucose levels. Ketones in bilateral cardiac blood and PCF were increased in diabetic ketoacidosis and fatal alcohol abuse as well as in most cases of hyperthermia (heatstroke), hypothermia (cold exposure) and malnutrition. These findings suggest that combined analysis of glucose, HbA1c and ketones in blood and body fluids is useful to investigate not only fatal diabetic metabolic disorders but also death processes due to other causes, including alcohol and MA abuse, as well as thermal disorders, sepsis and malnutrition.

    The effect of administration of different doses of Pterocarpus santalinus L. bark extracts in normal and diabetic rats, on blood glucose levels was evaluated in this study. Among the three fractions (aqueous, ethanol and hexane), ethanolic fraction at the dose of 0.25 g/kg body weight showed maximum antihyperglycemic activity. The same dose did not cause any hypoglycemic activity in normal rats. The results were compared with the diabetic rats treated with glibenclamide and the antihyperglycemic activity of ethanolic extract of PS bark at the dose of 0.25 g/kg b.w. was found to be more effective than that of glibenclamide.

    Data of routine chemical and hematological laboratory tests regarding outpatients were collected in four different hospitals of the provinces of Ferrara, Rovigo and Bologna. Data of about 1500 subjects per hospital were cumulated without preliminary selection of patients; sex, age and pregnancy status were also recorded. At the end of the collection, the second (and third) record of the same patient was discarded; only those referring to the first examination were retained. In this report we consider only the values of the blood sugar level which were obtained by enzymatic methods. Descriptive statistics and regression analysis were performed utilizing a CDC CYBER 70/76 computer. The means and the variances of the data collected at the four hospital laboratories were very similar (Tab 1). The interlaboratory analysis of variance was poorly significant. All frequency distributions were leptocurtic and skewed to the right (Fig. 1). The blood sugar level tend to increase with age (Tab. 2). This correlation is graphically depicted in a two-dimensional plot (Fig 2) in which the regression line and the 2, 5 and 97,5 percentile levels corrected for age were also reported. We think that this diagram may be more helpful to the clinicians interpreting laboratory results than the usual "normal values". PMID:7284101

Effect of VCO to leucocyte differential count, glucose levels and blood creatinine of hyperglycemic and ovalbumin sensitized Mus musculus Balb/c. Nusantara Bioscience 1: 1-8. Chemical medicines and insulin can decrease glucose blood level on hyperglycemic patients with macro vascular side effect. Diabetes and allergy incidences are influenced by quality and quantity of leucocytes. Lauric acid within VCO reports decreased glucose blood level of diabetes and some allergy incidents. The purpose of the study is to know the effect of VCO on glucose blood level, differential leucocytes count and creatinine blood level on hyperglycemic and normoglicemic ovalbumin sensitized mice. Forty five (45 male (mice of Mus musculus Balb/c with average weight of 35 g are divided into 9 groups with 5 repetitions, those are 4 non alloxan groups and 5 alloxan induced hyperglycemic groups. On 22nd day to 36th day they are sensitize to ovalbumin as allergen. Blood sample was obtained by orbital vena using heparin as anti coagulant in order measuring glucose blood level by GOD method to 6 times, on 1st, 4th, 18th, 22nd, 32nd and 37th days, then are tested by ANOVA followed by DMRT 0.05.

    Full Text Available Periodontal inflammation is a periodontal disorder of high prevalence in the population. Chronic periodontitis is associated with the accumulation of plaque and calculus as local factors, and systemic factors such an diabetes mellitus (DM and HIV infection. Cytokine, especially IL-1β as inflammatory mediator for periodontal disease, may directly stimulated iNOS (inducible nitric oxide synthase expression and NO (nitric oxide production by β-cells, resulting in NO-mediated β-cell damage. The leucotoxin and proteases produced by periodontal pathogens will induce chemotactic and phagocytotic defect; therefore causing decreased PMN phagocytotic function. Hyperglicemia which occurs in diabetic patients increases calcium influx to the cell, resulting in the increased cytosol’s calcium ([Ca 2+]i level and; therefore, resulting in dysfunction of PMN and impaired PMN phagocytotic function. Advanced glycosilation endproduct in NIDDM binds to monocytes resulting in the increase of pro-inflammatory cytokines (IL-1, TNFα and produces activation of macrophages and osteoclasts. Hyperglicemia activates diacyl glycerol (DAG-protein kinase C (PKC, thus increasing PGE2 and cytokine expression that induce inflammation and periodontal tissue destruction processes. Studies on the effect of scaling to remove calculus disposition on blood glucose control and cellular immune response in DM patient has never been carried out. The aim of the study was to analyze the effect of scaling as non-surgical periodontal therapy on immune response (IL-1β level and PMN phagocytotic function and blood glucose level of type 2 diabetic patients. Subjects were diabetic patients, 60 controlled-DM (CDM and 60 uncontrolled-DM (UCDM, in Metabolic-Endocrinology Clinic of Ciptomangunkusumo Hospital, aged 40-60 years. The subjects were divided into treatment (scaling and control group, and cellular immune response and diabetic status, before and 6 weeks after treatment were evaluated

    Surgical procedures performed using spinal anesthetic techniques present a special challenge to anesthesiologists, because patients are awake and are exposed to multiple anxiety provoking visual and auditory stimuli. Therefore, this study was carried out to define the effect of music on the level of cortisol, blood glucose and physiological variables in patients under spinal anesthesia. In this semi-experimental research, 90 men aging from 18-48 years with ASA (acetylsalicylic acid) class I, who underwent urological and abdominal surgery, were investigated. Patients were divided randomly into three groups of thirty subjects. Music group (headphone with music), Silence group (headphone without music) and the control group (without interference). The level of cortisol and blood sugar was measured half an hour before and after the operation. Moreover, the physiological indicators in each of these three groups were monitored and recorded from ten minutes before getting spinal anesthesia to ten minutes after the operation. The level of blood cortisol didn't have any increase in the music group after operation compared to the time before that. However, in the groups of silence and control this level had risen (pmusic group had declined and in the other two groups it had increased. Our data showed that listening to music during surgery under regional anesthesia has effects on cortisol levels and some of the physiological variables. Therefore the researcher offers to be used music therapy as a complementary method in patients on the reduce anxiety. PMID:27350774

    Full Text Available Introduction: Diabetic people are more at risk of diseases such as vascular, kidneys and eye diseases, compared with normal people. Since Vit C competitively replaces glucose in most chemical reactions; so inhibit on non enzymatic glycosylation such as hemoglobin and lipoproteins, it seems that Vit C can be effective to prevent diabetic complications .In this study effect of Vit C supplements on blood sugar and fats level in type II diabetic patients was investigated. Methods: This study was conducted as a clinical trial using paired random sampling on 136 type II diabetic patients. At first, the patients weights, age, type of diet were recorded .Then their fasting blood glucose (FBS, glycosylated hemoglobin (HbAIC, Cholesterol, triglyceride, HDL and LDL were measured. After that the patients were divided in two randomized groups. The first group (control was subject of administration of Vit C supplement (1250 mg, 5 times a day, for a period of 3 months and the second group received placebo. Data were analyzed by paired t- test and SPSS Software. Results: In this study most of patients were women (62.2% of control group and 64.7% of placebo group. The mean age between the control group and placebo group were reported 51.2 ± 6.8 and 50.37± 9.71 years respectively. At the end of study , after 3 months of administration of Vit C supplement to control group, the mean concentration of FBS, LDL triglyceride Cholesterol and glycosylated hemoglobin has been reduced significantly with respect to the placebo group and the mean value of HDL has been increased as well. Conclusion: The finding shows that Vit C supplements might reduce the amount of glucose, lipids and glycosylated hemoglobin in patients with type 2 diabetes. Therefore, its consumption in diabetic patients can be recommended and as a result patient complications will be significantly reduced.

    Full Text Available Background: Amlodipine used as many cardiac conditions esp in hypertension. Diabetes affects cardiovascular system adversely. So this study was done to see effect of amlodipine on blood glucose level and its interaction with commonly used oral hypoglycemic agents in diabetic & non diabetic albino rabbits. Methods: Rabbits were divided into nine groups of 6 rabbits in each group. I and II group were non-diabetic given normal saline and amlodipine respectively. Group III to IX were made diabetic by using alloxan monohydrate (150mg/kg i.p. & given normal saline, glimepiride, metformin, pioglitazone, amlodipine + glimepiride, amlodipine + metformin and amlodipine + pioglitazone respectively. All drugs were given orally once daily for 7 day except group VII, VIII and IX in which glimepiride, metformin and pioglitazone were added on 7th day. After GTT blood glucose level were measured at 0, 1, 2 and 6 hours on 7th day in all groups by using spectrophotometer. Results: After 7 days of treatment the amlodipine produced significant hyperglycemia in normal rabbits. Amlodipine on combination, causes significant decreased in hypoglycemic effect of glimepiride, significant increased the hypoglycemic effect of metformin, while no significant changes in hypoglycemic effects of pioglitazone in diabetic rabbits. Conclusion: The present study shows that amlodipine causes hyperglycemia in normal rabbits. Amlodipine significantly altered hypoglycemic effect of glimepiride and metformin as compared to control group. If these finding are true to human beings then amlodipine should be use cautiously in diabetic patient on oral hypoglycemic drugs. [Int J Basic Clin Pharmacol 2013; 2(6.000: 768-771

    This article compares the findings of three studies that explored the role of increased blood glucose in improving memory function for subjects who ate breakfast. An initial improvement in memory function for these subjects was found to correlate with blood glucose concentrations. In subsequent studies, morning fasting was found to adversely affect the ability to recall a word list and a story read aloud, as well as recall items while counting backwards. Failure to eat breakfast did not affect performance on an intelligence test. It was concluded that breakfast consumption preferentially influences tasks requiring aspects of memory. In the case of both word list recall and memory while counting backwards, the decline in performance associated with not eating breakfast was reversed by the consumption of a glucose-supplemented drink. Although a morning fast also affected the ability to recall a story read aloud, the glucose drink did not reverse this decline. It appears that breakfast consumption influences cognition via several mechanisms, including an increase in blood glucose. PMID:9537627

    Full Text Available Background: Morphine withdrawal usually results in undesired outcomes , despite partial benefits of alternative medication such as methadone, because of the lack of mental sedation during the withdrawal period, may not lead to the desired result. In this study, forced exercise by treadmill is used to manage morphine dependence in animal model. Materials and Methods: Forty adult male mice were divided into 5 groups, from which 4 groups became dependent by increasing daily doses of morphine for 6 days (20-45 mg/kg, SC. Afterwards, the animals were treated for 21 days by either of the following protocol: Positive control (dependent received once daily 45 mg/kg of morphine sulfate (SC for 21 day, group under treatment by clonidine (0.4 mg/kg, SC for 21 day group under treatment by forced exercise by treadmill for 21 day, group under treatment by combination of clonidine (0.4 mg/kg, SC and forced exercise by treadmill for 21day and the negative control group(independent received saline injection like other groups. Each of this administration was injected at 8 AM. Finally, in the test day (day 28, all animals received a single dose of naloxone (3 mg/kg, SC at 8 AM and then were observed for withdrawal signs, and Total Withdrawal Score (TWS was determined as described previously. After withdrawal sign evaluation for evaluation of stress level of dependent mice, blood cortisol and glucose level were measured in non-fasting situations well. Results: This study showed that TWS significantly decreased in all treatment groups in comparison with positive control group (P < 0.001. Moreover, blood cortisol and glucose level significantly decreased in group under treatment by clonidine (0.4 mg/kg and group under treatment by combination of clonidine (0.4 mg/kg and forced exercise by treadmill groups in comparison with control positive (dependent (P < 0.05. Conclusion: This study suggested that forced exercise can be useful as adjunct therapy in dependent people

    Previous studies have shown that the PDK2 and ABCG2 genes play important roles in many aspects of gout development in European populations. However, a detailed genotype-phenotype analysis was not performed. The aim of the present study was to investigate the potential association between variants in these two genes and metabolism-related quantitative phenotypes relevant to gout in a Chinese Tibetan population. In total, 316 Chinese Tibetan gout patients were recruited from rheumatology outpatient clinics and 6 single nucleotide polymorphisms in PDK2 and ABCG2 were genotyped, which were possible etiologic variants as identified in the HapMap Chinese Han Beijing population. A significant difference in blood glucose levels was detected between different genotypes of rs2728109 (P = 0.005) in the PDK2 gene. We also detected a significant difference in the mean serum uric levels between different genotypes of rs3114018 (P = 0.004) in the ABCG2 gene. All P values remained significant after Bonferroni's correction for multiple testing. Our data demonstrate potential roles for PDK2 and ABCG2 polymorphisms in the metabolic phenotypes of Tibetan gout patients, which may provide new insights into the etiology of gout. Further studies are required to confirm these findings. PMID:26909964

    Full Text Available We examined resource allocation priorities in the framework of an updated Maslow hierarchy of fundamental human needs. In Experiment 1, the participants in the food abundance priming condition viewing photos of high-calorie food allocated more money to savings than to spending. However, the participants preferred spending to savings under the condition of mating availability priming with romantic photographs. In Experiment 2, before and after drinking either water or a sugary beverage, fasting participants rated photos of a conversation between a man and a woman. Water drinking lowered the rating scores of mating intentions as well as blood glucose (BG levels. The sugary drink buffered this decline in sexual perceptivity. Overall, the change in BG levels was positively associated with changes in the ratings of mating intentions but was not associated with other likelihood ratings. These results suggest that both external cues of food and mating resources and internal BG fluctuation regulate the cognitive priority of physiological needs versus mate acquisition and retention.

  8. A moderate elevation of blood glucose level increases the effectiveness of thermoradiotherapy in a rat tumor model I. relative contributions of glucose and heating to tumor acidification

    International Nuclear Information System (INIS)

    Purpose: To establish dose-effect relationships for tumor acidification induced by heat and glucose as a basis for testing the value of adding glucose administration to combined heat and x-ray treatment at clinically achievable glucose and temperature levels. Methods and Materials: Rhabdomyosarcoma BA1112 was grown s.c. in the upper leg of 16-20-week-old Wag/Rij rats. Animals were given 2 consecutive 100-min periods of saline (S) or glucose (G) infusion, while keeping tumor temperature at 37 deg., 42 deg., or 43 deg. C for 1 or 2 periods, in various combinations, each involving 6 animals. Glucose was infused i.v. as a 20% solution at 2.4-3 g/kg/h. Tumors were heated using 2,450-MHz electromagnetic radiation, and tumor pH was measured using a 0.7 mm fiberoptic probe. Results: Mean overall baseline pH was 7.00 (SD 0.10). The change induced by G37G43 (i.e., glucose infusion for a full 200 min, first 100 min at 37 deg. C, final 100 min at 43 deg. C) was -0.48±0.03 (SEM) pH units, and -0.17 ± 0.03 for S37S43. The effect of G37G42 was -0.37±0.03 pH units, compared with -0.08±0.02 for S37S42 and -0.28±0.04 for glucose alone (G37G37). Glucose was less effective when given after or fully parallel to heating: -0.21±0.02 pH units for S43G37 and -0.37±0.02 for G43G43. Conclusion: The glucose-induced tumor pH drop is much more pronounced than that induced by heat, both of which are dose dependent. The effects of glucose and heat seem additive if heating is started when glucose-induced acidification has reached its plateau level, but the overall effect is diminished if administration is fully simultaneous or in reversed order. Schedule G37G43 is optimal with respect to tumor acidification. Its predicted superiority in thermoradiotherapy as compared with S37S42, S37S43, and G37G42 treatment regimens was confirmed in a subsequent experimental tumor control study

    Full Text Available Summary: The effects of the hydromethanolic  extract of Indigofera pulchra on blood glucose levels of alloxan induced and normoglycemic Wistar rats has been investigated. Three doses of the extract (250mg/Kg, 500mg/Kg and 1000mg/Kg were administered intraperitoneally. The dose of 1000mg/Kg of the extract did not significantly alter the blood glucose levels of Alloxan induced diabetic Wistar rats after 4, 8 and 24 hours of treatment. However, the doses of 500 mg/Kg of the extract did significantly (p<0.05 decrease the blood glucose levels of Alloxan diabetic Wistar rats at 4 and 24 hours while  the dose of 250 mg/Kg of the extract did significantly (p<0.05 decrease the blood glucose levels of Alloxan diabetic Wistar rats at 4, 8 and 24 hours. In normoglycemic rats, the dose of 1000mg/Kg of the extract significantly (p<0.05 decrease the blood glucose levels at 8 and 24 hours only. Also the dose of 500 mg/kg significantly (p<0.05 decrease the blood glucose levels at 24 hours while the dose of 250 mg/kg significantly (p<0.05 in the blood glucose levels at 8 and 24 hours. The phytochemical screening revealed the presences of tannins, saponins, flavonoids and steroids. The median lethal dose (LD50 in rats was calculated to be 2,154.1 mg/kg bodyweight. In conclusion, the doses of the extract has shown both significant (p<0.05 hypoglycemic and anti-hyperglycemic effects in Wistar rats.   Industrial relevance: The search for more effective and hypoglycemic agents has continue to be an area of research interest, because of the less side effects and easily affordable  medicinal plants has, when compared to the synthetic drugs. Indigofera pulchra is a very virgin plant and promising base on these current findings. The phytochemical screening revealed the present of phenolic compounds, tannins steroids, saponins and alkaloids. Elucidation of those secondary metabolites would be more effective in the treatment of this illness.

    Full Text Available Background Urtica dioica L. (stinging nettle has been accepted for decreasing blood glucose levels; however, the exact mechanism of its anti-hyperglycemic effect remains to be understood. Objectives We aimed to examine the effects of ethanolic extract of stinging nettle leaves on blood glucose levels and gene expression of Glucose Transporter 2 (Glut2 in liver of alloxan-induced diabetic mice. Materials and Methods Twenty-four male Naval medical research institute (NMRI mice were randomly divided to three groups. The control group received saline (10 mL/kg, intraperitoneally for eight days, the diabetic group received three days of injections of alloxan (200 mg/kg, intraperitoneally followed by five days of injections of ethanol (20%, and the diabetic + nettle extract group received alloxan for three days followed by five days of injections of the nettle extract (150 mg/kg. Mice were weighed before and after treatments (on days one and nine. On day nine, mice were sacrificed, blood samples were collected for measuring glucose levels and liver was dissected to examine changes in the Glut2 gene expression with the semi-quantitative reverse-transcription-polymerase chain reaction (RT-PCR method. Results The results showed that the nettle extract significantly decreased high levels of blood glucose (P < 0.001. The nettle extract also had a preventive effect on decrease in body weight. In addition, the results showed that the Glut2 gene expression was increased in liver of diabetic mice (P < 0.05 and was significantly prevented by the nettle extract in diabetic + nettle extract group (P < 0.05. Conclusions It can be concluded that the nettle extract can reduce blood glucose levels in diabetic mice, at least partly, by influencing the Glut2 gene expression in mice liver.

    Pieter de Mol

    Full Text Available BACKGROUND: Due to increasing numbers of people with diabetes taking part in extreme sports (e.g., high-altitude trekking, reliable handheld blood glucose meters (BGMs are necessary. Accurate blood glucose measurement under extreme conditions is paramount for safe recreation at altitude. Prior studies reported bias in blood glucose measurements using different BGMs at high altitude. We hypothesized that glucose-oxidase based BGMs are more influenced by the lower atmospheric oxygen pressure at altitude than glucose dehydrogenase based BGMs. METHODOLOGY/PRINCIPAL FINDINGS: Glucose measurements at simulated altitude of nine BGMs (six glucose dehydrogenase and three glucose oxidase BGMs were compared to glucose measurement on a similar BGM at sea level and to a laboratory glucose reference method. Venous blood samples of four different glucose levels were used. Moreover, two glucose oxidase and two glucose dehydrogenase based BGMs were evaluated at different altitudes on Mount Kilimanjaro. Accuracy criteria were set at a bias 6.5 mmol/L and <1 mmol/L from reference glucose (when <6.5 mmol/L. No significant difference was observed between measurements at simulated altitude and sea level for either glucose oxidase based BGMs or glucose dehydrogenase based BGMs as a group phenomenon. Two GDH based BGMs did not meet set performance criteria. Most BGMs are generally overestimating true glucose concentration at high altitude. CONCLUSION: At simulated high altitude all tested BGMs, including glucose oxidase based BGMs, did not show influence of low atmospheric oxygen pressure. All BGMs, except for two GDH based BGMs, performed within predefined criteria. At true high altitude one GDH based BGM had best precision and accuracy.

    Full Text Available The effect of kappa-carrageenan consumption on blood glucose level were studied on diabetic male wistar rat (Ratus norvegicus.The rats were made diabetic by aloxan injection, and then were given that a ration contains 5, 10, 15, 20% (w/w kappa-carrageenan, standard ration (negative control, and parental glibenklamid (positive control. The results showed that the standard ration could not reduce blood glucose from hyperglycemic to normal level, while the ration contained kappacarrageenan could. The higher kappa-carrageenan seaweed level in the ration has higher capacity to decrease blood glucose level. The ration containing 20% and 15% kappa-carrageenan could reduce blood glucose in 18 and 21 days, respectively.The effect of this ration was similar to that of glibenklamid which reduced blood glucose to normal level in 18 days. The ration containing 5 and 10% kappa-carrageenan could reduce blood glucose level; Blood glucose leve return to normal on the 21st day.

    Full Text Available To evaluate the effects of inspiratory loading on blood flow of resting and exercising limbs in patients with diabetic autonomic neuropathy. Ten diabetic patients without cardiovascular autonomic neuropathy (DM, 10 patients with cardiovascular autonomic neuropathy (DM-CAN and 10 healthy controls (C were randomly assigned to inspiratory muscle load of 60% or 2% of maximal inspiratory pressure (PImax for approximately 5 min, while resting calf blood flow (CBF and exercising forearm blood flow (FBF were measured. Reactive hyperemia was also evaluated. From the 20 diabetic patients initially allocated, 6 wore a continuous glucose monitoring system to evaluate the glucose levels during these two sessions (2%, placebo or 60%, inspiratory muscle metaboreflex. Mean age was 58 ± 8 years, and mean HbA1c, 7.8% (62 mmol/mol (DM and DM-CAN. A PImax of 60% caused reduction of CBF in DM-CAN and DM (P<0.001, but not in C, whereas calf vascular resistance (CVR increased in DM-CAN and DM (P<0.001, but not in C. The increase in FBF during forearm exercise was blunted during 60% of PImax in DM-CAN and DM, and augmented in C (P<0.001. Glucose levels decreased by 40 ± 18.8% (P<0.001 at 60%, but not at 2%, of PImax. A negative correlation was observed between reactive hyperemia and changes in CVR (Beta coefficient = -0.44, P = 0.034. Inspiratory muscle loading caused an exacerbation of the inspiratory muscle metaboreflex in patients with diabetes, regardless of the presence of neuropathy, but influenced by endothelial dysfunction. High-intensity exercise that recruits the diaphragm can abruptly reduce glucose levels.

    Purpose: Fluorescence lifetime imaging ophthalmoscopy (FLIO) provides in vivo metabolic mapping of the ocular fundus. Changes in FLIO have been found in e.g. diabetes patients. The influence of short term metabolic changes caused by blood glucose level changes on is unknown. Aim of this work is the detection of short-term changes in fundus autofluorescence lifetime during an oral glucose tolerance test. Methods: FLIO was performed in 10 healthy volunteers (29+/-4 years, fasting for 12h) using a scanning laser ophthalmoscope (30° fundus, 34μm resolution, excitation with 473nm diode laser with 70 ps pulses at 80 MHz repetition rate, detection in two spectral channels 500-560nm (ch1) and 560-720nm (ch2) using the timecorrelated single photon counting method). The blood glucose level (BGL) was measured by an Accu-Chek® Aviva self-monitoring device. Before and after a glucose drink (300ml solution, containing 75g of glucose (Accu-Chek® Dextrose O.G.T.), BGL and FLIO were measured every 15min. The FLIMX software package was applied to compute the average fluorescence lifetime τ on the inner ring of the ETDRS grid using a modified 3-exponential approach. Results: The results are given as mean +/- standard deviation over all volunteers in ch1. Baseline measurement: BGL: 5.3+/-0.4 mmol/l, τ1: 49+/-6ps. A significant reduction (α=5% Wilcoxon rank-sum test) in τ1 is detected after 15min (BGL: 8.4+/-1.1 mmol/l, τ1: 44+/-5ps) and after 90min (BGL: 6.3+/-1.4 mmol/l, τ1: 41+/-5ps). Results of ch2 show smaller reductions in the fluorescence lifetimes over time.

This was cross-sectional study, conducted among Saudi school children. Fasting blood samples were collected from 2149 children, 1138 (53%) boys and 1011 (47%) girls, aged 6 to 18 years old. Samples were analyzed on the Architect c8000 Chemistry System (Abbott Diagnostics, USA) for glucose, cholesterol, triglycerides, HDL and LDL. Reference intervals were established by nonparametric methods between the 2.5th and 97.5th percentiles. Significant differences were observed between boys and girls for cholesterol and triglycerides levels in all age groups (P < 0.02). Only at age 6-7 years and at adolescents, HDL and LDL levels were found to be significant (P < 0.001). No significant differences were seen in glucose levels except at age 12 to 13 years. Saudi children have comparable serum cholesterol levels than their Western counterparts. This may reflect changing dietary habits and increasing affluence in Saudi Arabia. Increased lipid screening is anticipated, and these reference intervals will aid in the early assessment of cardiovascular and diabetes risk in Saudi pediatric populations.

    Full Text Available We here propose a novel Raman spectroscopy method that permits the noninvasive measurement of blood glucose concentration. To reduce the effects of the strong background signals produced by surrounding tissue and to obtain the fingerprint Raman lines formed by blood analytes, a laser was focused on the blood in vessels in the skin. The Raman spectra were collected transcutaneously. Characteristic peaks of glucose (1125 cm(-1 and hemoglobin (1549 cm(-1 were observed. Hemoglobin concentration served as an internal standard, and the ratio of the peaks that appeared at 1125 cm(-1 and 1549 cm(-1 peaks was used to calculate the concentration of blood glucose. We studied three mouse subjects whose blood glucose levels became elevated over a period of 2 hours using a glucose test assay. During the test, 25 Raman spectra were collected transcutaneously and glucose reference values were provided by a blood glucose meter. Results clearly showed the relationship between Raman intensity and concentration. The release curves were approximately linear with a correlation coefficient of 0.91. This noninvasive methodology may be useful for the study of blood glucose in vivo.

    Full Text Available Diabetes is a metabolic disorder which affects whole body systems including reproductive system. Diabetes is also a contributing factor to infertility. Metformin is one of the most common drugs to control hyperglycemia. In this study, 36 adult Sprague-Dawley female rats (170-210 g were divided into 3 groups (control, diabetic and diabetic-treated by metformin. In second and third groups, diabetes was induced by streptozotocin injection (45 mg kg-1, IP and the third group was treated by metformin hydrochloride (100 mg kg-1 day-1, PO for 8 weeks. Body weights were compared and blood glucose, gonadotropins and sexual hormones were measured. In diabetic group the blood glucose level significantly (P < 0.05 increased in comparison with that of control and metformin-treated diabetic rats. The results also revealed that, in the untreated diabetic rats, the mean body weights and pituitary-gonadal axis hormones were significantly (P < 0.05 reduced in comparison with the control. Although there were significant (P < 0.05 reduction in mean body weights in metformin-treated diabetic rats, reduction in pituitary-gonadal axis hormones was not as sharp as in untreated diabetic rats and only level of progesterone was significantly (P < 0.05 reduced in comparison with the control. The results of this investigation revealed that there was a clear relationship between experimental diabetes with body weight and pituitary-gonadal axis hormones, and treatment with metformin relatively restored diabetic complications.

  5. Use of a blood glucose meter for radiochromic film analysis in blood irradiation

    International Nuclear Information System (INIS)

    The use of a diabetic blood glucose meter for radiochromic film dosimetry in blood irradiation using x-ray beams on a medical linear accelerator has been investigated. The glucose meter provides optical density analysis in the visible and infrared region using a reflectance measurement technique. By comparing the 'blood sugar' level output with standard calibration gafchromic films a calibration curve is produced for quantitative analysis. Results show that a reproducible dose to meter output curve can be fitted using a second order polynomial function and that blood irradiation doses in vitro were measured to within 7.9% mean error (as compared to ionization chamber results) using the blood glucose meter. This level of accuracy falls below that measured with a standard densitometer (4.3%); however, results show that the blood glucose meter, which would be available in any haematology department, produces an adequate measure of gafchromic film optical density for blood irradiation dosimetry.

    Regular monitoring of blood sugar level is important for the management of diabetes. The Near-Infra-Red (NIR) spectroscopy method is a promising approach and this involves some form of contact with the body skin. It is noted that the skin temperature does fluctuate with the environment and physiological conditions and the temperature has an influence on the glucose measurement. In this paper, in-vitro and in-vivo investigations on the temperature influence on blood glucose measurement were studied. The in-vitro results from FTIR spectrometer show that sample temperature has significant influence on water absorption, which significantly affects the glucose absorption measurement. The in-vivo results show that when skin temperature around the measurement site is taken into consideration, the prediction of blood glucose level greatly improves.

    An amperometric needle-type electrochemical glucose sensor intended for tear glucose measurements is described and employed in conjunction with a 0.84 mm i.d. capillary tube to collect microliter volumes of tear fluid. The sensor is based on immobilizing glucose oxidase on a 0.25 mm o.d. platinum/iridium (Pt/Ir) wire and anodically detecting the liberated hydrogen peroxide from the enzymatic reaction. Inner layers of Nafion and an electropolymerized film of 1,3-diaminobenzene/resorcinol greatly enhance the selectivity for glucose over potential interferences in tear fluid, including ascorbic acid and uric acid. Further, the new sensor is optimized to achieve very low detection limits of 1.5 ± 0.4 μM of glucose (S/N = 3) that is required to monitor glucose levels in tear fluid with a glucose sensitivity of 0.032 ± 0.02 nA/μM (n = 6). Only 4-5 μL of tear fluid in the capillary tube is required when the needle sensor is inserted into the capillary. The glucose sensor was employed to measure tear glucose levels in anesthetized rabbits over an 8 h period while also measuring the blood glucose values. A strong correlation between tear and blood glucose levels was found, suggesting that measurement of tear glucose is a potential noninvasive substitute for blood glucose measurements, and the new sensor configuration could aid in conducting further research in this direction.

    Full Text Available Rice koji is considered a readily accessible functional food that may have health-promoting effects. We investigated whether white, yellow, and red koji have the anti-obesity effect in C57BL/6J mice fed a high-fat diet (HFD, which is a model for obesity. Mice were fed HFD containing 10% (w/w of rice koji powder or steamed rice for 4 weeks. Weight gain, epididymal white adipose tissue, and total adipose tissue weight were significantly lower in all rice koji groups than in the HFD-rice group after 4 weeks. Feed efficiency was significantly reduced in the yellow koji group. Blood glucose levels were significantly lower in the white and red koji groups with HOMA-R and leptin levels being reduced in the white koji group. White and red koji increased glucose uptake and GLUT4 protein expression in L6 myotube cells. These results showed that all rice koji have the anti-obesity or anti-diabetes effects although the mechanisms may differ depending on the type of rice koji consumed.

    Aronia berries have many potential effects on health. Previous human studies have shown that aronia juice may be useful for treatment of obesity disorders. Recently, we have reported that aronia juice has an inhibitory effect on dipeptidyl peptidase (DPP IV) activity and that the DPP IV inhibitor in aronia juice was identified as cyanidin 3,5-diglucoside. In this study, we found that body weights and blood glucose levels were reduced in diabetes model KK-Ay mice given aronia juice. We also found that weights of white adipose tissues were reduced in KK-Ay mice given aronia juice. Furthermore, levels of DPP IV activity in the serum and liver from KK-Ay mice were lower than those in the serum and liver from C57BL/6JmsSlc mice. Interestingly, although levels of DPP IV activity were not changed in the serum and liver from aronia-juice-administered KK-Ay mice, levels of DPP IV activity were increased in those from aronia-juice-administered C57BL/6JmsSlc mice. Furthermore, α-glucosidase activity was inhibited in the upper region of the small intestine from aronia-juice-administered KK-Ay mice but not in the lower region. Inhibition of α-glucosidase activity in the upper portion of the small intestine induced a reduction of glucose-dependent insulinotropic polypeptide (GIP) level. The results suggest that DPP IV activity in diabetic mice is inhibited by aronia juice, that the GIP level in the upper region of the small intestine is reduced by inhibition of α-glucosidase activity and that weights of adipose tissues are reduced by aronia juice.

    Diets high in calories and sweetened foods with disaccharides frequently lead to exaggerated postprandial spikes in blood glucose. This state induces immediate oxidant stress and free radicals which trigger oxidative stress-linked diabetic complications. One of the therapeutic approaches for decreasing postprandial hyperglycemia is to retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes, α-amylase and α-glucosidases, in the digestive organs. Therefore, the inhibi...

    In previous studies, we reported that the blood glucose levels of mice with type I diabetes mellitus (TIDM) was reduced with orally administered silk gland powder from silkworms transgenic for human insulin-like growth factor-I (hIGF-I). However, potential safety hazards could not be eliminated because the transgenic silk gland powder contained heterologous DNA, including the green fluorescent protein (gfp) and neomycin resistance (neo) genes. These shortcomings might be overcome if the recombinant hIGF-I were secreted into the sericin layer of the cocoon. In this study, silkworm eggs were transfected with a novel piggyBac transposon vector, pigA3GFP-serHS-hIGF-I-neo, containing the neo, gfp, and hIGF-I genes controlled by the sericin-1 (ser-1) promoter with the signal peptide DNA sequence of the fibrin heavy chain (Fib-H) and a helper plasmid containing the piggyBac transposase sequence under the control of the Bombyx mori actin 3 (A3) promoter, using sperm-mediated gene transfer to generate the transformed silkworms. The hIGF-I content estimated by enzyme-linked immunosorbent assay was approximately 162.7 ng/g. To estimate the biological activity of the expressed hIGF-I, streptozotocin-induced TIDM mice were orally administered sericin from the transgenic silkworm. The blood glucose levels of the mice were significantly reduced, suggesting that the extract from the transgenic hIGF-I silkworm cocoons can be used as an orally administered drug. PMID:24632065

  19. Optical coherence tomography for blood glucose monitoring through signal attenuation

    Development of non-invasive techniques for glucose monitoring is crucial to improve glucose control and treatment adherence in patients with diabetes. Hereafter, Optical Coherence Tomography (OCT) may offer a good alternative for portable glucometers, since it uses light to probe samples. Changes in the object of interest can alter the intensity of light returning from the sample and, through it, one can estimate the sample's attenuation coefficient (μt) of light. In this work, we aimed to explore the behavior of μt of mouse's blood under increasing glucose concentrations. Different samples were prepared in four glucose concentrations using a mixture of heparinized blood, phosphate buffer saline and glucose. Blood glucose concentrations were measured with a blood glucometer, for reference. We have also prepared other samples diluting the blood in isotonic saline solution to check the effect of a higher multiple-scattering component on the ability of the technique to differentiate glucose levels based on μt. The OCT system used was a commercial Spectral Radar OCT with 930 nm central wavelength and spectral bandwidth (FWHM) of 100 nm. The system proved to be sensitive for all blood glucose concentrations tested, with good correlations with the obtained attenuation coefficients. A linear tendency was observed, with an increase in attenuation with higher values of glucose. Statistical difference was observed between all groups (p<0.001). This work opens the possibility towards a non-invasive diagnostic modality using OCT for glycemic control, which eliminates the use of analytes and/or test strips, as in the case with commercially available glucometers.

    This book tackles the problem of overshoot and undershoot in blood glucose levels caused by delay in the effects of carbohydrate consumption and insulin administration. The ideas presented here will be very important in maintaining the welfare of insulin-dependent diabetics and avoiding the damaging effects of unpredicted swings in blood glucose – accurate prediction enables the implementation of counter-measures. The glucose prediction algorithms described are also a key and critical ingredient of automated insulin delivery systems, the so-called “artificial pancreas”. The authors address the topic of blood-glucose prediction from medical, scientific and technological points of view. Simulation studies are utilized for complementary analysis but the primary focus of this book is on real applications, using clinical data from diabetic subjects. The text details the current state of the art by surveying prediction algorithms, and then moves beyond it with the most recent advances in data-based modeling o...

    Full Text Available Diabetes has recently become a leading cause of death worldwide. To date, although there is no means to cure or prevent diabetes, appropriate medication and blood sugar monitoring can enhance treatment efficiency, alleviate the symptoms, and diminish the complications of the condition. This review article deals with current growth areas in the market for blood glucose sensors and possible future alternatives, which are generally considered to be the point sample test and the continuous glucose monitor (CGM. Most glucose sensors are enzyme-based, whereas others are enzyme-free. The former class is sensitive and some products are extensively employed for daily self-sensing and in hospital environments as reliable diagnostic tools. The latter class, particularly the boronic acid fluorescent sensor, is facile and extremely promising. Practicality demands that all types of sensors offer accuracy, specificity, and real-time detection.

  6. Optimizing 18F-FDG PET/CT imaging of vessel wall inflammation: the impact of 18F-FDG circulation time, injected dose, uptake parameters, and fasting blood glucose levels

    International Nuclear Information System (INIS)

    18F-FDG PET is increasingly used for imaging of vessel wall inflammation. However, limited data are available on the impact of methodological variables, i.e. prescan fasting glucose, FDG circulation time and injected FDG dose, and of different FDG uptake parameters, in vascular FDG PET imaging. Included in the study were 195 patients who underwent vascular FDG PET/CT of the aorta and the carotids. Arterial standardized uptake values (meanSUVmax), target-to-background ratios (meanTBRmax) and FDG blood-pool activity in the superior vena cava (SVC) and the jugular veins (JV) were quantified. Vascular FDG uptake values classified according to the tertiles of prescan fasting glucose levels, the FDG circulation time, and the injected FDG dose were compared using ANOVA. Multivariate regression analyses were performed to identify the potential impact of all variables described on the arterial and blood-pool FDG uptake. Tertile analyses revealed FDG circulation times of about 2.5 h and prescan glucose levels of less than 7.0 mmol/l, showing a favorable relationship between arterial and blood-pool FDG uptake. FDG circulation times showed negative associations with aorticmeanSUVmax values as well as SVC and JV FDG blood-pool activity, but positive correlations with aortic and carotidmeanTBRmax values. Prescan glucose levels were negatively associated with aortic and carotidmeanTBRmax and carotidmeanSUVmax values, but were positively correlated with SVC blood-pool uptake. The injected FDG dose failed to show any significant association with vascular FDG uptake. FDG circulation times and prescan blood glucose levels significantly affect FDG uptake in the aortic and carotid walls and may bias the results of image interpretation in patients undergoing vascular FDG PET/CT. The injected FDG dose was less critical. Therefore, circulation times of about 2.5 h and prescan glucose levels less than 7.0 mmol/l should be preferred in this setting. (orig.)

    2011-06-01

    Full Text Available Diets high in calories and sweetened foods with disaccharides frequently lead to exaggerated postprandial spikes in blood glucose. This state induces immediate oxidant stress and free radicals which trigger oxidative stress-linked diabetic complications. One of the therapeutic approaches for decreasing postprandial hyperglycemia is to retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes,α-amylase and α-glucosidases, in the digestive organs. Therefore, the inhibitory activity of Korean onion (Allium cepa L. extract against rat intestinal α-glucosidases, such as sucrase, maltase, and porcine pancreatic α-amylase were investigated in vitro and in vivo. The content of quercetin in ethyl alcohol extract of onion skin (EOS was 6.04 g/100 g dried weight of onion skin. The in vitro half-maximal inhibitory concentrations (IC50 of EOS and quercetin, a major phenolic in onion, on rat intestinal sucrase were 0.40 and 0.11 mg/mL, respectively. The postprandial blood glucose lowering effects of EOS and quercetin were compared to a known type 2 diabetes drug (Acarbose, a strong α-glucosidase inhibitor in the Sprague-Dawley (SD rat model. In rats fed on sucrose, EOS significantly reduced the blood glucose spike after sucrose loading. The area under the blood glucose-time curve (AUClast in EOS-treated SD rats (0.5 g-EOS/kg was significantly lower than in untreated SD rats (259.6 ± 5.1 vs. 283.1 ± 19.2 h·mg/dL. The AUClast in quercetin-treated SD rats (0.5 g-quercetin/kg was similar to in EOS-treated group (256.1 ± 3.2 vs. 259.6 ± 5.1 h·mg/dL. Results from this study indicates that although quercetin does have blood glucose lowering potential via α-glucosidase inhibition, there are other bioactive compounds present in onion skin. Furthermore, the effects of two weeks administration of EOS in a high carbohydrate-dietary mixture (Pico 5053 on sucrase and maltase activities in intestine were evaluated in SD rat model

    The effect of the protein source of the ration (soybean meal, cottonseed cake, corn gluten and fish meal) and the time (period) of blood sample taking was examined on the content of glucose and triacylglycerols in the blood during the initial lactation period. Thirty-six ewes of the Thessaloniki crossbred type were randomly allocated to 4 groups. The ewes of each group were fed ad libitum with one of the 4 different rations, respectively. From each ewe 4 blood samples were taken in different times. The experimental design was factorial 4x4 with 9 replicates with main factors the main protein source (ration), as well as the time of blood sample taking. The protein source effect on glucose and triacylglycerol concentration in blood was not significant, while that of time of blood sample taking was significant. The interaction "ration" X "time" of sampling for the glucose and TGC concentration was not significant. PMID:7487483

  17. Blood-Brain Glucose Transfer: Repression in Chronic Hyperglycemia

    Science.gov (United States)

    Gjedde, Albert; Crone, Christian

    1981-10-01

    Diabetic patients with increased plasma glucose concentrations may develop cerebral symptoms of hypoglycemia when their plasma glucose is rapidly lowered to normal concentrations. The symptoms may indicate insufficient transport of glucose from blood to brain. In rats with chronic hyperglycemia the maximum glucose transport capacity of the blood-brain barrier decreased from 400 to 290 micromoles per 100 grams per minute. When plasma glucose was lowered to normal values, the glucose transport rate into brain was 20 percent below normal. This suggests that repressive changes of the glucose transport mechanism occur in brain endothelial cells in response to increased plasma glucose.

    Full Text Available Safety and anti-diabetic effects of Glucolevel, a mixture of dry extract of leaves of the Juglans regia L, Olea europea L, Urtica dioica L and Atriplex halimus L were evaluated using in vivo and in vitro test systems. No sign of toxic effects (using LDH assay were seen in cultured human fibroblasts treated with increasing concentrations of Glucolevel. Similar observations were seen in vivo studies using rats (LD50: 25 g/kg. Anti-diabetic effects were evidenced by the augmentation of glucose uptake by yeast cells (2-folds higher and by inhibition of glucose intestinal absorption (∼49% in a rat gut-segment. Furthermore, treatment with Glucolevel of Streptozotocin-induced diabetic rats for 2–3 weeks showed a significant reduction in glucose levels [above 400 ± 50 mg/dl to 210 ± 22 mg/dl (P < 0.001] and significantly improved sugar uptake during the glucose tolerance test, compared with positive control. In addition, glucose levels were tested in sixteen human volunteers, with the recent onset of type 2 diabetes mellitus, who received Glucolevel tablets 1 × 3 daily for a period of 4 weeks. Within the first week of Glucolevel consumption, baseline glucose levels were significantly reduced from 290 ± 40 to 210 ± 20 mg/dl. At baseline, a subgroup of eleven of these subjects had glucose levels below 300 mg% and the other subgroup had levels ≥ 300 mg%. Clinically acceptable glucose levels were achieved during the 2–3 weeks of therapy in the former subgroup and during the 4th week of therapy in the latter subgroup. No side effect was reported. In addition, a significant reduction in hemoglobin A1C values (8.2 ± 1.03 to 6.9 ± 0.94 was found in six patients treated with Glucolevel. Results demonstrate safety, tolerability and efficacy of herbal combinations of four plants that seem to act differently but synergistically to regulate glucose-homeostasis.

    We develop a spectroscopy technique that combines the advantages of both the frequency-resolved coherent anti-Stokes Raman scattering (CARS) and the time-resolved CARS. We use broadband preparation pulses to get an instantaneous coherent excitation of multiplex molecular vibration levels and subsequent optically shaped time-delayed narrowband probing pulse to detect these vibrations. This technique can suppress the nonresonant background and retrieve the molecular fingerprint signal efficiently and rapidly. We employ this technique to glucose detection, the final goal of which is accurate, non-invasive (i.e. painless) and continuous monitoring of blood glucose concentration in the Diabetes diagnosis to replace the current glucose measurement process, which requires painful fingerpricks and therefore cannot be performed more than a few times a day. We have gotten the CARS spectra of glucose aqueous solution down to 2 mM.

They were underwent complete physical examination and laboratory investigations. Twelve healthy subjects were subjected for distill water inhalation for 10 min, and after one week they received inhalation of honey solution (60% wt/v) for 10 min. Another 12 healthy subjects received inhalation of 10% dextrose for 10 min. Blood glucose level, plasma insulin and C-peptide, blood pressure, heart rate and PEFR were estimated before inhalation and during 2-3 hrs after inhalation, at 30 min intervals. Random blood glucose level was estimated in eight patients with poorly controlled diabetes mellitus, and repeated 30 min after honey inhalation. One week later, fasting blood glucose level was estimated in each patient and blood glucose level was re-estimated during three hrs after honey inhalation, at 30 min intervals. Glucose tolerance test was performed in another eight patients with type-2 diabetes mellitus, and after one week the procedure was repeated with inhalation of honey, which was started immediately after ingestion of glucose. Six hypertensive patients received honey inhalation for 10 min; supine blood pressure and heart rate were measured before and after inhalation. - Results showed that in normal subjects distill water caused mild elevation of blood glucose level, mild lowering of plasma insulin, and significant reduction of plasma C-peptide. 10% dextrose inhalation caused mild reduction of plasma insulin and C-peptide and unremarkable changes in blood glucose level. No significant changes were obtained in blood pressure, heart rate or PEFR after distill

    Hypoglycemia-abnormal decrease in blood sugar-is a major obstacle in the management of diabetes and prevention of long-term complications, and it may impose serious effects on the brain, including impairment of memory and other cognitive functions. This paper presents the development of a non-invasive sensor with miniaturized telemetry device in a wrist-watch for monitoring glucose concentration in blood. The sensor concept is based on optical chirality of glucose level in the interstitial fluid. The wrist watch consists of a laser power source of the wavelength compatible with the glucose. A nanofilm with specific chirality is placed at the bottom of the watch. The light then passes through the film and illuminates a small area on the skin. It has been documented that there is certain concentration of sugar level is taken by the intertitial fluid from the blood stream and deposit a portion of it at the dead skin. The wrist-watch when in contact with the outer skin of the human will thus monitor the glucose concentration. A wireless monitoring system in the watch then downloads the data from the watch to a Palm or a laptop computer.

    This study aimed to investigate the independent and joint association of blood pressure (BP), homocysteine (Hcy), and fasting blood glucose (FBG) levels with brachial-ankle pulse wave velocity (baPWV, a measure of arterial stiffness) in Chinese hypertensive adults.The analyses included 3967 participants whose BP, Hcy, FBG, and baPWV were measured along with other covariates. Systolic BP (SBP) was analyzed as 3 categories (SBP < 160 mmHg; 160 to 179 mmHg; ≥ 180 mmHg); Hcy as 3 categories (< 10 μmol/L; 10 to 14.9 μmol/L; ≥ 15.0 μmol/L) and FBG: normal (FBG < 5.6 mmol/L), impaired (5.6 mmol/L ≤ FBG < 7.0 mmol/L), and diabetes mellitus (FBG ≥ 7.0 mmol/L). We performed linear regression analyses to evaluate their associations with baPWV with adjustment for covariables.When analyzed individually, BP, Hcy, and FBG were each associated with baPWV. When BP and FBG were analyzed jointly, the highest baPWV value (mean ± SD: 2227 ± 466 cm/s) was observed in participants with FBG ≥ 7.0 mmol/L and SBP ≥ 180 mmHg (β = 432.5, P < 0.001), and the lowest baPWV value (mean ± SD: 1692 ± 289 cm/s) was seen in participants with NFG and SBP < 160 mmHg. When Hcy and FBG were analyzed jointly, the highest baPWV value (2072 ± 480 cm/s) was observed in participants with FBG ≥ 7.0 mmol/L and Hcy ≥ 15.0 μmol/L (β = 167.6, P < 0.001), while the lowest baPWV value (mean ± SD: 1773 ± 334 cm/s) was observed in participants with NFG and Hcy < 10 μmol/L.In Chinese hypertensive adults, SBP, Hcy, and FBG are individually and jointly associated with baPWV.Our findings underscore the importance of identifying individuals with multiple risk factors of baPWV including high SBP, FBG, and Hcy.

    {sup 18}F-FDG PET is increasingly used for imaging of vessel wall inflammation. However, limited data are available on the impact of methodological variables, i.e. prescan fasting glucose, FDG circulation time and injected FDG dose, and of different FDG uptake parameters, in vascular FDG PET imaging. Included in the study were 195 patients who underwent vascular FDG PET/CT of the aorta and the carotids. Arterial standardized uptake values ({sub mean}SUV{sub max}), target-to-background ratios ({sub mean}TBR{sub max}) and FDG blood-pool activity in the superior vena cava (SVC) and the jugular veins (JV) were quantified. Vascular FDG uptake values classified according to the tertiles of prescan fasting glucose levels, the FDG circulation time, and the injected FDG dose were compared using ANOVA. Multivariate regression analyses were performed to identify the potential impact of all variables described on the arterial and blood-pool FDG uptake. Tertile analyses revealed FDG circulation times of about 2.5 h and prescan glucose levels of less than 7.0 mmol/l, showing a favorable relationship between arterial and blood-pool FDG uptake. FDG circulation times showed negative associations with aortic{sub mean}SUV{sub max} values as well as SVC and JV FDG blood-pool activity, but positive correlations with aortic and carotid{sub mean}TBR{sub max} values. Prescan glucose levels were negatively associated with aortic and carotid{sub mean}TBR{sub max} and carotid{sub mean}SUV{sub max} values, but were positively correlated with SVC blood-pool uptake. The injected FDG dose failed to show any significant association with vascular FDG uptake. FDG circulation times and prescan blood glucose levels significantly affect FDG uptake in the aortic and carotid walls and may bias the results of image interpretation in patients undergoing vascular FDG PET/CT. The injected FDG dose was less critical. Therefore, circulation times of about 2.5 h and prescan glucose levels less than 7.0 mmol

    Objective To investigate the correlation of glycosylated hemoglobin (HbAlc) and impaired glucose regulation(IGR). Methods Seventy-five g oral glucose tolerance test(OGTT)and HbAlc levels were carried out among our hospital staffs. The subjects were determined fasting plasma glucose (FPG), oral glucose 2 h plasma glucose(2 h PG)and HbAlc, plasma glucose levels and HbAlc levels were determined by glucose oxidase method and high performance liquid chromatogram ( HPLC). The inclusion criteria of subjects was FPG<7.0 mmol/L and 2 h PG<11.1 mmol/L, without diabetes, hemoglobin disease, hepatopathy and renopathy. The selected object contained 726 subjects (197 male, 529 female, mean age (39±10)), including NGT 636 subjects(87.6% ) , IGR 90 subjects( 12.4% ). The diagnostic criteria of IGR selected 1999 WHO diagnostic criteria for diabetes. χ~2 test was used for rate comparison. Pearson correlation analysis was used for bivariate analysis selected. Results (1)2.3% occurred IGR among HbAlc≤5.7% subjects, while 89. 3% occurred IGR among HbAlc≥5.8% subjects. When HbAlc ≥5.8% ,the sensibility, specificity, PV + , and PV - were 83% , 99% , 0.89, 0.98, respectively. (2) Between HbAlc level 5.8% group and HbAlc 5.7% group, the difference of prevalence of the OGTT diagnosed IFG,IGT,IGR had statistically significance(χ~2 value was 10. 077,22. 219 and 27. 780, P<0.01 or P<0.001), (3) HbAlc levels was significant positive correlation with the prevalence of IFG,IGT,IGR(rralue was 0.957,0.928 and 0.936, all P<0.01).Conclusions (1) Compared with OGTT, HbAlc had consistency for predicting IGR, and the optimal critical value of HbAlc with OGTT diagnosed IGR was 5.8%. (2) HbAlc levels was significant positive correlation with the blood sugar level of the OGTT diagnosed IFG, IGT, IGR, and when HbAlc =5.8%, its relevance is most closely. The present study suggests that the HbAlc ≥5.8% patients should be examined OGTT in order to identify whether the IGR.%目的 探讨研究糖化

    Tail biopsy is a common procedure that is performed to obtain genetic material for determining genotype of transgenic mice. The use of anesthetics or analgesics is recommended, although identifying safe and effective drugs for this purpose has been challenging. We evaluated the effects of topical 2.5% lidocaine-2.5% prilocaine cream applied to the distal tail tip at 5 or 60 min before biopsy, immersion of the tail tip for 10 seconds in ice-cold 70% ethanol just prior to biopsy, and immersion of the tail tip in 0.5% bupivacaine for 30 s after biopsy. Mice were 7, 11, or 15 d old at the time of tail biopsy. Acute behavioral responses, plasma corticosterone, and blood glucose were measured after biopsy, and body weight and performance in elevated plus maze and open-field tests after weaning. Ice-cold ethanol prior to biopsy prevented acute behavioral responses to biopsy, and both ice-cold ethanol and bupivacaine prevented elevations in corticosterone and blood glucose after biopsy. Tail biopsy with or without anesthesia did not affect body weight or performance on elevated plus maze or open-field tests. We recommend the use of ice-cold ethanol for topical anesthesia prior to tail biopsy in mice 7 to 15 d old. PMID:27423152

    Postprandial blood glucose control is the major goal in the treatment of diabetes. Here, we investigated the effect of sea cucumber saponins (SCSs) on postprandial blood glucose levels. SCS inhibited yeast as well as rat intestinal α-glucosidase activity in a dose-dependent manner and showed better inhibition of yeast α-glucosidases compared to the positive control. Further studies were performed using ICR mice treated with SCS and starch or SCS alone by oral gavage. Unexpectedly, SCS increased postprandial blood glucose levels a short time (1 h) after oral gavage. The serum corticosterone (CORT) level showed a consistent correlation with glucose levels. In vitro experiments confirmed that SCS treatment increased the secretion of CORT in the Y1 adrenal cell line. Overall, these studies demonstrated that SCS gavage could inhibit α-glucosidase activity but cannot attenuate postprandial blood glucose level within short time periods. The underlying mechanisms are probably related to increased serum CORT levels. PMID:26932154

    2012-02-01

    Electrical stimulation at acupuncture points (acupoints) has been investigated for its utility in lowering blood glucose in hyperglycemic humans and animal models. Only two studies were found using electroacupuncture in human subjects, and in both of these, the participants were normal (nondiabetic) and electrical stimulation was carried out at several acupoints. It had a hypoglycemic effect in obese women with calorific restriction diet using electrical stimulation of 2 Hz for 30 minutes/day for 20 days, but no change occurred in blood glucose of fasted patients in the other study using 1 Hz for 15 minutes. Fourteen animal studies were found, of which, 11 were performed in diabetic and normal rats. A hypoglycemic effect was observed in fasted type 1 diabetic rats using the Zusanli (ST36) leg acupoint with electrical stimulation of 15 Hz for 30 minutes and 60 minutes. In fasted type 2 diabetic rats, blood glucose was lowered using the Zusanli acupoint with electrical stimulation parameters of 15 Hz and 10 mA for 30 minutes. Also, using the Zhongwan (CV12) abdomen acupoint with electrical stimulation parameters of 15 Hz and 10 mA for 90 minutes had a hypoglycemic effect in fasted type 2 diabetic rats. In fasted normal rats, electrical stimulation of 2 Hz or 15 Hz for 30 minutes at the Zusanli or Zhongwan acupoint caused a decrease in blood glucose. Future studies are required in fasted diabetic rats to determine the effect of electroacupuncture on blood levels of insulin, lipids, fatty acids and β-endorphin, and blood flow and nerve conduction velocity. Studies with fasted normal and diabetic human subjects treated by electroacupuncture are warranted using data from animal experiments to inform such studies. PMID:22309901

    Full Text Available Artificial sweeteners, such as saccharin or cyclamic acid are synthetically manufactured sweetenings. Known for their low energetic value they serve especially diabetic and adipose patients as sugar substitutes. It has been hypothesized that the substitution of sugar with artificial sweeteners may induce a decrease of the blood glucose. The aim of this study was to determine the reliability of this hypothesis by comparing the influence of regular table sugar and artificial sweeteners on the blood glucose concentration. In this pilot-study 16 patients were included suffering from adiposity, pre-diabetes and hypertension. In the sense of a cross-over design, three test trials were performed at intervals of several weeks. Each trial was followed by a test free interval. Within one test trial each patient consumed 150 ml test solution (water that contained either 6 g of table sugar (“Kandisin” with sweetener free serving as control group. Tests were performed within 1 hr after lunch to ensure conditions comparable to patients having a desert. Every participant had to determine their blood glucose concentration immediately before and 5, 15, 30 and 60 minutes after the intake of the test solution. For statistics an analysis of variance was performed. The data showed no significant changes in the blood glucose concentration. Neither the application of sugar (F4;60 = 1.645; p = .175 nor the consumption of an artificial sweetener (F2.068;31.023 = 1.551; p > .05 caused significant fluctuations in the blood sugar levels. Over a time frame of 60 minutes in the control group a significant decrease of the blood sugar concentration was found (F2.457;36.849 = 4.005; p = .020 as a physiological reaction during lunch digestion.

    Full Text Available Summary: Evaluation of hypoglycemic activity of methanolic stem bark extract of Adansonnia digitata in Wistar rats has been  investigated. Antidiabetic potentials of the plant extract at the doses of 100,200 and 400 mg/kg intraperitoneally administered on Streptozocin diabetes Wistar rats. Treatment of streptozocin diabetic Wistar rats with the extract caused a significant (P<0.05 reduction in the blood glucose levels when compared with control. The dose of 100mg/kg shown a significant decreased (p<0.05 after 1, 3 5 and 7 hours of extract administration when compared to control normal saline. Also the dose of 200 mg/kg shown a significant decreased (p<0.05 after 3, 5 and 7 hours of extract administration. The dose of 400 mg/kg also shown a significant decreased( p<0.05 after 5 and 7 hours of extract administration when compared to control normal saline. The highest activity resides at the dose of 100 mg/kg with percentage glycemic change of 51 % after 7 hours of extract administration while the other two doses 200 and 400 mg/kg have glycemic change of 39% and 31% respectively after 7 hours of extract administration. The phytochemical screening revealed the presences of tannins, carbohydrate, terpenes, saponins, flavonoids and alkaloids. The median lethal dose ( LD50 in mice was calculated to be 1264.9 mg/kg bodyweight. This result suggests that the methanolic stem bark of Adansonnia digitata possess antidiabetic effect on streptozocin induced diabetic Wistar rats.   Industrial relevance: The herbal medicines are getting more importance in the treatment of diabetes and others ailments because of the hazardous adverse effect of the current therapy used to treat those ailments using synthetic drugs.

    The academic and public interest in blood glucose and its relationship to decision making has been increasing over the last decade. To investigate and evaluate competing theories about this relationship, we conducted a psychometric meta-analysis on the effect of blood glucose on decision making. We...... identified 42 studies relating to 4 dimensions of decision making: willingness to pay, willingness to work, time discounting, and decision style. We did not find a uniform influence of blood glucose on decision making. Instead, we found that low levels of blood glucose increase the willingness to pay...... and willingness to work when a situation is food related, but decrease willingness to pay and work in all other situations. Low levels of blood glucose increase the future discount rate for food; that is, decision makers become more impatient, and to a lesser extent increase the future discount rate for money...

    2009-06-01

    Diabetes Mellitus (DM) is a widespread disease and a serious public health problem. Low Level LASER Therapy (LLLT) has been found to reduce glycaemia on DM type 1 patients, an observation requiring further research especially as regards characteristics of treatment protocol. The purpose of this work is to continue the line of research and propose a specific protocol for LLLT use. In spring 2008 a 48 year old man, DM type 1 insulin dependent patient has been submitted to 810 nm wavelength LLLT treatment in specific body areas daily for 3 weeks and then once a week for 4 weeks until normalization of glycaemia. Medical supervision was present before, during and after application. Insulin was reduced progressively and then stopped. A gradual reduction of glycaemia was noted during the course of treatment. In successive follow-ups a reduction in HbA1c was noted. Results confirm previous observations and need for further research on large cohorts. The indication that LASER may become a valuable addition to DM type 1 treatment is confirmed and the proposed protocol appears to be effective. The case presented merits review since it reports a therapeutic challenge, contributes to advance in medical science and spawns research.

    Full Text Available Abstract Background The will to eat is a decision associated with conditioned responses and with unconditioned body sensations that reflect changes in metabolic biomarkers. Here, we investigate whether this decision can be delayed until blood glucose is allowed to fall to low levels, when presumably feeding behavior is mostly unconditioned. Following such an eating pattern might avoid some of the metabolic risk factors that are associated with high glycemia. Results In this 7-week study, patients were trained to estimate their blood glucose at meal times by associating feelings of hunger with glycemic levels determined by standard blood glucose monitors and to eat only when glycemia was Conclusion Subjects could be trained to accurately estimate their blood glucose and to recognize their sensations of initial hunger at low glucose concentrations. These results suggest that it is possible to make a behavioral distinction between unconditioned and conditioned hunger, and to achieve a cognitive will to eat by training.

    veis intraoperatórios mais elevados de glicemia estão associados com maior morbidade no pós-operatório de cirurgia cardíaca pediátrica.BACKGROUND: Anesthesia for pediatric cardiac surgery is systematically performed in severely ill patients under abnormal physiological conditions. In the intraoperative period, there are significant variations in blood volume, body temperature, plasma composition, and tissue blood flow, in addition to activation of inflammation, with important consequences. Serial measurements of blood glucose levels can indicate states of exacerbation of the neuroendocrine-metabolic response to trauma, serving as prognostic markers of morbidity in that population. OBJECTIVE: To correlate perioperative blood glucose levels of children undergoing cardiac surgery with the occurrence of postoperative complications, and to compare intraoperative blood glucose levels according to perioperative conditions. METHODS: Information regarding the surgical/anesthetic procedure and perioperative conditions of patients was collected from the medical records. The mean perioperative blood glucose levels in the groups of patients with and without postoperative complications and the frequencies of perioperative conditions were compared by use of odds ratio and non-parametric univariate analyses. RESULTS: Higher intraoperative blood glucose levels were observed in individuals who had postoperative complications. Prematurity, age group, type of anesthesia, and character of the procedure did not influence the mean intraoperative blood glucose level. The use of extracorporeal circulation (ECC was associated with higher blood glucose levels during surgery. In procedures with ECC, higher blood glucose levels were observed in individuals who had infectious and cardiovascular complications. In surgeries without ECC, that association was observed with infectious and hematological complications. CONCLUSION: Higher intraoperative blood glucose levels are associated with higher morbidity

    Reactive hypoglycemia induced by late dumping syndrome is often observed after gastrectomy. However, no effective therapy has yet been fully established. We herein describe a case in which concurrent therapy with a low-carbohydrate diet using low-glycemic-index food and an alpha-glucosidase inhibitor, miglitol, very effectively ameliorated the postprandial fluctuations in the blood glucose and plasma insulin levels in a patient with reactive hypoglycemia due to late dumping syndrome following total gastrectomy. The administration of miglitol under a low-carbohydrate diet using low-glycemic-index food may therefore be an ideal treatment for reactive hypoglycemia due to late dumping syndrome. PMID:27150868

  14. Blood Glucose Control Using a Novel Continuous Blood Glucose Monitor and Repetitive Intravenous Insulin Boluses: Exploiting Natural Insulin Pulsatility as a Principle for a Future Artificial Pancreas

    2013-01-01

    Full Text Available The aim of this study was to construct a glucose regulatory algorithm by employing the natural pulsatile pattern of insulin secretion and the oscillatory pattern of resting blood glucose levels and further to regulate the blood glucose level in diabetic pigs by this method. We developed a control algorithm based on repetitive intravenous bolus injections of insulin and combined this with an intravascular blood glucose monitor. Four anesthetized pigs were used in the study. The animals developed a mildly diabetic state from streptozotocin pretreatment. They were steadily brought within the blood glucose target range of 4.5–6.0 mmol/L in 21 to 121 min and kept within that range for 128 to 238 min (hypoglycemic values varied from 2.9 to 51.1 min. The study confirmed our hypotheses regarding the feasibility of this new principle for blood glucose control, and the algorithm was constantly improved during the study to produce the best results in the last animals. The main obstacles were the drift of the IvS-1 sensor and problems with the calibration procedure, which calls for an improvement in the sensor stability before this method can be applied fully in new studies in animals and humans.

    Depression is more common among diabetes people than in the general population. In the present study, blood glucose change in depression animal model was characterized by various types of hyperglycemia models such as d-glucose-fed-, immobilization stress-, and drug-induced hyperglycemia models. First, the ICR mice were enforced into chronic restraint stress for 2h daily for 2 weeks to produce depression animal model. The animals were fed with d-glucose (2g/kg), forced into restraint stress for 30min, or administered with clonidine (5μg/5μl) supraspinally or spinally to produce hyperglycemia. The blood glucose level in depression group was down-regulated compared to that observed in the normal group in d-glucose-fed-, restraint stress-, and clonidine-induced hyperglycemia models. The up-regulated corticosterone level induced by d-glucose feeding or restraint stress was reduced in the depression group while the up-regulation of plasma corticosterone level is further elevated after i.t. or i.c.v. clonidine administration in the depression group. The up-regulated insulin level induced by d-glucose feeding or restraint stress was reduced in the depression group. On the other hand, blood corticosterone level in depression group was up-regulated compared to the normal group after i.t. or i.c.v. clonidine administration. Whereas the insulin level in depression group was not altered when mice were administered clonidine i.t. or i.c.v. Our results suggest that the blood glucose level in depression group is down-regulated compared to the normal group during d-glucose-fed-, immobilization stress-, and clonidine-induced hyperglycemia in mice. The down-regulation of the blood glucose level might be one of the important pathophysiologic changes in depression.

    Blood glucose fluctuation is associated with diabetic nephropathy. However, the mechanism by which blood glucose fluctuation accelerates renal injury is not fully understood. The aim of the present study was to assess the effects of blood glucose fluctuation on diabetic nephropathy in rats and investigate its underlying mechanism. Diabetes in the rats was induced by a high sugar, high-fat diet, and a single dose of STZ (35 mg/kg)-injected intraperitoneally. Unstable blood sugar models were induced by subcutaneous insulin injection and intravenous glucose injection alternately. Body weight, glycosylated hemoglobin A1c (HbAlc), blood urea nitrogen (BUN), serum creatinine (Scr), and Creatinine clearance (Ccr) were assessed. T-SOD activity and MDA level were measured by assay kit. Change in renal tissue ultrastructure was observed by light microscopy and electron microscopy. Phosphorylated ser/thr protein kinase (p-AKT) (phosphor-Ser473), phosphorylated glycogen synthase kinase-3 beta (p-GSK-3β) (phosphor-Ser9), Bcl-2-associated X protein (BAX), B cell lymphoma/leukemia 2 (BCL-2), and cleaved-cysteinyl aspartate-specific proteinase-3 (caspase-3) levels were detected by immunohistochemistry and Western blot. We observed that BUN and Scr were increased in diabetic rats, and Ccr was decreased. Furthermore, blood glucose fluctuations could exacerbate the Ccr changes. Renal tissue ultrastructure was also seriously injured by glucose variability in diabetic rats. In addition, glucose fluctuation increased the oxidative stress of renal tissue. Moreover, fluctuating blood glucose decreased p-AKT level and BCL-2, and increased p-GSK-3β, BAX, cleaved-caspase-3 levels, and ratio of BAX/BCL-2 in the kidneys of diabetic rats. In conclusion, these results suggest that blood glucose fluctuation accelerated renal injury is due, at least in part to its oxidative stress promoting and inhibiting the AKT signaling pathway in diabetic rats.

    Recent technological advancements in the photonics industry have led to a resurgence of interest in optical glucose sensing and to realistic progress toward the development of an optical glucose sensor. Such a sensor has the potential to significantly improve the quality of life for the estimated 16 million diabetics in this country by making routine glucose measurements more convenient. Currently over 100 small companies and universities are working to develop noninvasive or minimally invasive glucose sensing technologies, and optical methods play a large role in these efforts. It has become overwhelmingly clear that frequent monitoring and tight control of blood sugar levels are requisite for effective management of Diabetes mellitus and reduction of the complications associated with this disease. The pain and trouble associated with current "finger-stick" methods for blood glucose monitoring result in decreased patient compliance and a failure to control blood sugar levels. Thus, the development of a convenient noninvasive blood glucose monitor holds the potential to significantly reduce the morbidity and mortality associated with Diabetes. A method and apparatus for noninvasive measurement of blood glucose concentration based on transilluminated laser beam via the Index Finger has been reported in this paper. This method depends on photodiode based laser operating at 632.8 nm wavelength. During measurement, the index finger is inserted into the glucose sensing unit, the transilluminated optical signal is converted into an electrical signal, compared with the reference electrical signal, and the obtained difference signal is processed by signal processing unit which presents the results in the form of blood glucose concentration.

  11. The fluctuation of blood glucose, insulin and glucagon concentrations before and after insulin therapy in type 1 diabetes

    Science.gov (United States)

    Arif, Idam; Nasir, Zulfa

    2015-09-01

    A dynamical-systems model of plasma glucose, insulin and glucagon concentrations has been developed to investigate the effects of insulin therapy on blood glucose, insulin and glucagon regulations in type 1 diabetic patients. Simulation results show that the normal regulation of blood glucose concentration depends on insulin and glucagon concentrations. On type 1 diabetic case, the role of insulin on regulating blood glucose is not optimal because of the destruction of β cells in pancreas. These β cells destructions cause hyperglycemic episode affecting the whole body metabolism. To get over this, type 1 diabetic patients need insulin therapy to control the blood glucose level. This research has been done by using rapid acting insulin (lispro), long-acting insulin (glargine) and the combination between them to know the effects of insulin therapy on blood glucose, insulin and glucagon concentrations. Simulation results show that these different types of insulin have different effects on blood glucose concentration. Insulin therapy using lispro shows better blood glucose control after consumption of meals. Glargin gives better blood glucose control between meals and during sleep. Combination between lispro and glargine shows better glycemic control for whole day blood glucose level.

    2016-03-01

    The development of adequate mathematical models for blood glucose dynamics may improve early diagnosis and control of diabetes mellitus (DM). We have developed a stochastic nonlinear second order differential equation to describe the response of blood glucose concentration to food intake using continuous glucose monitoring (CGM) data. A variational Bayesian learning scheme was applied to define the number and values of the system's parameters by iterative optimisation of free energy. The model has the minimal order and number of parameters to successfully describe blood glucose dynamics in people with and without DM. The model accounts for the nonlinearity and stochasticity of the underlying glucose-insulin dynamic process. Being data-driven, it takes full advantage of available CGM data and, at the same time, reflects the intrinsic characteristics of the glucose-insulin system without detailed knowledge of the physiological mechanisms. We have shown that the dynamics of some postprandial blood glucose excursions can be described by a reduced (linear) model, previously seen in the literature. A comprehensive analysis demonstrates that deterministic system parameters belong to different ranges for diabetes and controls. Implications for clinical practice are discussed. This is the first study introducing a continuous data-driven nonlinear stochastic model capable of describing both DM and non-DM profiles.

    Satish Kumar

    2014-01-01

    Full Text Available Objectives: To study the correlation between blood glucose levels and salivary glucose levels in type 2 diabetic patients, to study the relationship between salivary glucose levels and oral candidal carriage in type 2 diabetic patients and to determine whether salivary glucose levels could be used as a noninvasive tool for the measurement of glycemic control in type 2 diabetics. Study Design: The study population consisted of three groups: Group 1 consisted of 30 controlled diabetics and Group 2 consisted of 30 uncontrolled diabetics based on their random nonfasting plasma glucose levels. Group 3 consisted of 30 healthy controls. Two milliliters of peripheral blood was collected for the estimation of random nonfasting plasma glucose levels and glycosylated hemoglobin (HbA1c. Unstimulated saliva was collected for the estimation of salivary glucose. Saliva was collected by the oral rinse technique for the estimation of candidal counts. Results: The salivary glucose levels were significantly higher in controlled and uncontrolled diabetics when compared with controls. The salivary candidal carriage was also significantly higher in uncontrolled diabetics when compared with controlled diabetics and nondiabetic controls. The salivary glucose levels showed a significant correlation with blood glucose levels, suggesting that salivary glucose levels can be used as a monitoring tool for predicting glycemic control in diabetic patients. Conclusion: The present study found that estimation of salivary glucose levels can be used as a noninvasive, painless technique for the measurement of diabetic status of a patient in a dental set up. Increased salivary glucose levels leads to increased oral candidal carriage; therefore, oral diagnosticians are advised to screen the diabetic patients for any oral fungal infections and further management.

  16. Study on the relationship between blood glucose level and insulin resistance as pancreatic β-cell function in patients with type 2 diabetes mellitus (DM2)

    International Nuclear Information System (INIS)

    Objective: To investigate the relationship between serum immuno-reactive peptide (IR-CP) and true insulin (TI), pro-insulin (PI), immuno-reactive insulin (IR-I) contents and to calculate the insulin resistance (Home-IR), β-cell function (Homa-β) from these data in DM2 patients with different levels of fasting blood sugar (FBG<8.8 and ≥8.8 mmol/L). Methods: Fasting and 2h post- prandial serum TI, PI (with ELISA), IR-I, IR-CP (with RIA) contents were measured in 73 patients with DM2 and Homa-IR, Homa-β were calculated with Homa-model from these data, The 73 DM2 patients were of two groups: Group A, FBG≥8.8 mmol/L, n=46; Group B, FBG<8.8 mmol/L, n=27. Results: The Homa-β calculated from either TI or IR-I was significantly different in Group A and Group B patients. Homa-IR calculated from IR-I was also significantly different in the two groups of patients; however, Homa-IR calculated from TI was about the same in the two groups. relationship between C peptide and TI, PI, IR-I was less obvious in Group A than that in Group B. Both fasting and 2h TI in Group B were significantly higher than those in Group A; the other parameters tested were not much different. Conclusion: The higher FBG levels developed in Group A patients were mostly due to deterioration of β-cell function rather than increase of insulin resistance, as Homa-IR calculated from TI was not much different in the two groups. Further study on the management of diabetes should lay more emphasis on the change of β-cell function. (authors)

    Full Text Available Abstract Background Reductions in postprandial glycemia have been demonstrated previously with the addition of the novel viscous polysaccharide (NVP, PolyGlycopleX® (PGX®, to an OGTT or white bread. This study explores whether these reductions are sustained when NVP is added to a range of commonly consumed foods or incorporated into a breakfast cereal. Methods Ten healthy subjects (4M, 6F; age 37.3 ± 3.6 y; BMI 23.8 ± 1.3 kg/m2, participated in an acute, randomized controlled trial. The glycemic response to cornflakes, rice, yogurt, and a frozen dinner with and without 5 g of NVP sprinkled onto the food was determined. In addition, 3 granolas with different levels of NVP and 3 control white breads and one white bread and milk were also consumed. All meals contained 50 g of available carbohydrate. Capillary blood samples were taken fasting and at 15, 30, 45, 60, 90 and 120 min after the start of the meal. The glycemic index (GI and the glycemic reduction index potential (GRIP were calculated. The blood glucose concentrations at each time and the iAUC values were subjected to repeated-measures analysis of variance (ANOVA examining for the effect of test meal. After demonstration of significant heterogeneity, differences between individual means was assessed using GLM ANOVA with Tukey test to adjust for multiple comparisons. Results Addition of NVP reduced blood glucose response irrespective of food or dose (p Conclusion Sprinkling or incorporation of NVP into a variety of different foods is highly effective in reducing postprandial glycemia and lowering the GI of a food.

    Full Text Available Glucose mobilization and utilization in the periphery and central nervous system are important during exercise and are responsible for exercise efficacy. Magnesium (Mg is involved in energy production and plays a role in exercise performance. This study aimed to explore the effects of Mg on the dynamic changes in glucose and lactate levels in the muscle, blood and brain of exercising rats using a combination of auto-blood sampling and microdialysis. Sprague-Dawley rats were pretreated with saline or magnesium sulfate (MgSO4, 90 mg/kg, i.p. 30 min before treadmill exercise (20 m/min for 60 min. Our results indicated that the muscle, blood, and brain glucose levels immediately increased during exercise, and then gradually decreased to near basal levels in the recovery periods of both groups. These glucose levels were significantly enhanced to approximately two-fold (P<0.05 in the Mg group. Lactate levels in the muscle, blood, and brain rapidly and significantly increased in both groups during exercise, and brain lactate levels in the Mg group further elevated (P<0.05 than those in the control group during exercise. Lactate levels significantly decreased after exercise in both groups. In conclusion, Mg enhanced glucose availability in the peripheral and central systems, and increased lactate clearance in the muscle during exercise.

    Background The delivery of glucose from the blood to the brain involves its passage across the endothelial cells of the blood-brain barrier (BBB), which is mediated by the facilitative glucose transporter protein 1 (GLUT1), and then across the neural cell membranes, which is mediated by GLUT3. This study aimed to evaluate the dynamic influence of hyperglycemia on the expression of these GLUTs by measuring their expression in the brain at different blood glucose levels in a rat model of diabetes. This might help to determine the proper blood glucose threshold level in the treatment of diabetic apoplexy.Methods Diabetes mellitus was induced with streptozotocin (STZ) in 30 rats. The rats were randomly divided into 3 groups: diabetic group without blood glucose control (group DM1), diabetic rats treated with low dose insulin (group DM2),and diabetic rats treated with high dose insulin (group DM3). The mRNA and protein levels of GLUT1 and GLUT3 were assayed by reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry, respectively.Results Compared with normal control rats, the GLUT1 mRNA was reduced by 46.08%, 29.80%, 19.22% (P<0.01) in DM1, DM2, and DM3 group, respectively; and the GLUT3 mRNA was reduced by 75.00%, 46.75%, and 17.89% (P<0.01)in DM1, DM2, and DM3 group, respectively. The abundance of GLUT1 and GLUT3 proteins had negative correlation with the blood glucose level (P<0.01). The density of microvessels in the brain of diabetic rats did not change significantly compared with normal rats.Conclusions Chronic hyperglycemia downregulates GLUT1 and GLUT3 expression at both mRNA and protein levels in the rat brain, which is not due to the decrease of the density of microvessels. The downregulation of GLUT1 and GLUT3 expression might be the adaptive reaction of the body to prevent excessive glucose entering the cell that may lead to cell damage.

    Complementary metal oxide semiconductor (CMOS) image sensors have received great attention for their high efficiency in biological applications. The present work describes a CMOS image sensor-based whole blood glucose monitoring system through a point-of-care (POC) approach. A simple poly-ethylene terephthalate (PET) chip was developed to carry out the enzyme kinetic reaction at various concentrations (110–586 mg∕dL) of mouse blood glucose. In this technique, assay reagent is immobilized onto amine functionalized silica (AFSiO2) nanoparticles as an electrostatic attraction in order to achieve glucose oxidation on the chip. The assay reagent immobilized AFSiO2 nanoparticles develop a semi-transparent reaction platform, which is technically a suitable chip to analyze by a camera module. The oxidized glucose then produces a green color according to the glucose concentration and is analyzed by the camera module as a photon detection technique; the photon number decreases when the glucose concentration increases. The combination of these components, the CMOS image sensor and enzyme immobilized PET film chip, constitute a compact, accurate, inexpensive, precise, digital, highly sensitive, specific, and optical glucose-sensing approach for POC diagnosis.

    Full Text Available In this paper a stochastic modeling and optimization problem is developed for blood glucose and insulin regulatory system suitable for management of type-2 diabetes patients. The rates of arrival and consumption of glucose and insulin in the blood are assumed as Poisson parameters and developed a model through stochastic processes. A stochastic programming problem for maintaining the optimized glucose and insulin levels of the blood is developed. An objective function for maximizing the energy release subject to the constraints on the consumption of glucose is formulated. Sensitivity analysis was carried out and observed the model behaviour through influencing parameters. Enhancing the developed programming problem as desk top automation system will make this work more accessible to the decision makers of Health care industry.

    In this report, we present a paper membrane-based surface-enhanced Raman scattering (SERS) platform for the determination of blood glucose level using a nitrocellulose membrane as substrate paper, and the microfluidic channel was simply constructed by wax-printing method. The rod-shaped gold nanorod particles were modified with 4-mercaptophenylboronic acid (4-MBA) and 1-decanethiol (1-DT) molecules and used as embedded SERS probe for paper-based microfluidics. The SERS measurement area was simply constructed by dropping gold nanoparticles on nitrocellulose membrane, and the blood sample was dropped on the membrane hydrophilic channel. While the blood cells and proteins were held on nitrocellulose membrane, glucose molecules were moved through the channel toward the SERS measurement area. Scanning electron microscopy (SEM) was used to confirm the effective separation of blood matrix, and total analysis is completed in 5 min. In SERS measurements, the intensity of the band at 1070 cm(-1) which is attributed to B-OH vibration decreased depending on the rise in glucose concentration in the blood sample. The glucose concentration was found to be 5.43 ± 0.51 mM in the reference blood sample by using a calibration equation, and the certified value for glucose was 6.17 ± 0.11 mM. The recovery of the glucose in the reference blood sample was about 88 %. According to these results, the developed paper-based microfluidic SERS platform has been found to be suitable for use for the detection of glucose in blood samples without any pretreatment procedure. We believe that paper-based microfluidic systems may provide a wide field of usage for paper-based applications.

    To explore the possibility of lanthanides as the enhancer of insulin absorption, the promoting effects of lanthanide ions on the absorption of intrapulmonary delivered insulin and reduction of blood glucose were investigated by means of two approaches, preadministration and coadministration of lanthanide ions with insulin. The results indicate that, compared with the results of those given insulin only, lanthanide ions can effectively enhance the level of insulin and the reduction of glucose level in blood. These effects are dependent on lanthanide species and their concentrations. The mechanism was discussed.

    Intensive insulin therapy reduces mortality and morbidity in critically ill patients but imposes great demands on medical staff who must take frequent blood samples for the determination of glucose levels. A solution to this resourcing problem would be provided by an automated blood monitoring system. The aim of the present clinical study was to evaluate such a system comprising an automatic blood sampling unit linked to a glucose biosensor. Our approach was to determine the correlation and system error of the sampling unit alone and of the combined system with respect to reference levels over 12h in humans. Two venous cannulae were inserted to connect the automatic and reference systems to the subjects. Blood samples were taken at 15 and 30 min intervals. The median Pearson coefficient of correlation between manually and automatically withdrawn blood samples was 0.982 for the sampling unit alone and 0.950 for the complete system. The biosensor had a linear range up to 20 mmoll(-1) and a 95% response time of Titration Error Grid analysis suggested an acceptable treatment in 99.56% of cases. Implementation of a "Keep Vein Open" saline infusion into the automated blood sampling system reduced blood withdrawal failures through occluded catheters fourfold. In summary, automated blood sampling from a peripheral vein coupled with automatic glucose determination is a promising alternative to frequent manual blood sampling. PMID:19135351

    Objective:To observe the effect of mitiglinide combined laser photocoagulation on blood glucose, blood lipid and vascular endothelial function in diabetic retinopathy.Methods:A total of 106 patients with diabetic retinopathy treated in our hospital from January 2014 to January 2015 were selected and assigned into the separate group and combined group. Fifty-three patients in the separate group only received oral mitiginide, while other 53 patients in the combined group received oral mitiglinide and laster photocoagulation surgery. Before and after treatment, the FBG, 2hPBG, HbA1c, TC, TG, HDL-C, LDL-C, ET-1, VEGF, PEDF, ICAM-1, FMD of patients in the two groups were analyzed.Results: After treatment, the blood glucose and blood lipid indexes of patients in the two groups were improved significantly, and there was no statistical difference between the two groups. The ET-1, ICAM-1 and VEGF of patients in the two groups decreased, and the decrease of the combined group was more distinctly. The PEDF and FMD in the two groups all increased, and the combined group changed more obviously. The regression of the blood vessel and the recovery of visual acuity in the combined group were better than the separate group.Conclusions:Mitiglinide combined with laser photocoagulation can effectively improve the level of blood glucose and blood lipid, promote vascular endothelial function and inhibit the formation of retinal neovascularization so as to improve the visual acuity level.

    High blood glucose levels caused by excessive sugar consumption are detrimental to mammalian health and life expectancy. Despite consuming vast quantities of sugar-rich floral nectar, nectar-feeding bats are long-lived, provoking the question of how they regulate blood glucose. We investigated blood glucose levels in nectar-feeding bats (Glossophaga soricina) in experiments in which we varied the amount of dietary sugar or flight time. Blood glucose levels increased with the quantity of glucose ingested and exceeded 25 mmol l(-1) blood in resting bats, which is among the highest values ever recorded in mammals fed sugar quantities similar to their natural diet. During normal feeding, blood glucose values decreased with increasing flight time, but only fell to expected values when bats spent 75 per cent of their time airborne. Either nectar-feeding bats have evolved mechanisms to avoid negative health effects of hyperglycaemia, or high activity is key to balancing blood glucose levels during foraging. We suggest that the coevolutionary specialization of bats towards a nectar diet was supported by the high activity and elevated metabolic rates of these bats. High activity may have conferred benefits to the bats in terms of behavioural interactions and foraging success, and is simultaneously likely to have increased their efficiency as plant pollinators.

  19. Patient self-monitoring of blood glucose and refinements of conventional insulin treatment.

    The compelling evidence that blood glucose control will slow or prevent microvascular complications has stimulated research to find better ways of managing insulin-dependent diabetes. The excellent results obtained with "open loop" insulin infusion systems suggest that the relative failure of conventional treatment is the result of (1) a lack of appropriate feedback to the patient and (2) the use of insulin regimens which do not mimic physiologic insulinemia, particularly in the basal state. Doctors regard blood glucose measurements as an essential part of diabetic management and extension of this technology to patients has added a new dimension, particularly in the assessment of control. Nevertheless, home blood-glucose monitoring will not necessarily improve diabetic control; the best results have been obtained when it has been offered as part of a package deal which includes more investment of time and interest by patients and doctor together with joint discussions of problems and changes in treatment. The biggest problem with conventional twice daily insulin regimens is to sustain constant basal insulin levels during the night. Attempts to obtain fasting normoglycemia with an injection before supper often result in nocturnal hyperinsulinemia and hypoglycemia. This can usually be resolved by changing to a three times daily regimen with an extra injection of NPH insulin at bedtime. Three times daily insulin injections with feedback from home blood-glucose monitoring give as good blood glucose control as infusion systems and are cheaper and more acceptable to patients.

    2015-07-01

    We propose the signal processing technique of calculating a cross-correlation function and an average deviation between the continuous blood glucose and the interpolation of limited blood glucose samples to evaluate blood glucose monitoring frequency in a self-aware patient software agent model. The diabetic patient software agent model [1] is a 24-h circadian, self-aware, stochastic model of a diabetic patient's blood glucose levels in a software agent environment. The purpose of this work is to apply a signal processing technique to assist patients and physicians in understanding the extent of a patient's illness using a limited number of blood glucose samples. A second purpose of this work is to determine an appropriate blood glucose monitoring frequency in order to have a minimum number of samples taken that still provide a good understanding of the patient's blood glucose levels. For society in general, the monitoring cost of diabetes is an extremely important issue, and these costs can vary tremendously depending on monitoring approaches and monitoring frequencies. Due to the cost and discomfort associated with blood glucose monitoring, today, patients expect monitoring frequencies specific to their health profile. The proposed method quantitatively assesses various monitoring protocols (from 6 times per day to 1 time per week) in nine predefined categories of patient agents in terms of risk factors of health status and age. Simulation results show that sampling 6 times per day is excessive, and not necessary for understanding the dynamics of the continuous signal in the experiments. In addition, patient agents in certain conditions only need to sample their blood glucose 1 time per week to have a good understanding of the characteristics of their blood glucose.

    We previously used Gene Expression Signature technology to identify methazolamide (MTZ) and related compounds with insulin sensitizing activity in vitro. The effects of these compounds were investigated in diabetic db/db mice, insulin-resistant diet-induced obese (DIO) mice, and rats with streptozotocin (STZ)-induced diabetes. MTZ reduced fasting blood glucose and HbA1c levels in db/db mice, improved glucose tolerance in DIO mice, and enhanced the glucose-lowering effects of exogenous insulin administration in rats with STZ-induced diabetes. Hyperinsulinemic-euglycemic clamps in DIO mice revealed that MTZ increased glucose infusion rate and suppressed endogenous glucose production. Whole-body or cellular oxygen consumption rate was not altered, suggesting MTZ may inhibit glucose production by different mechanism(s) to metformin. In support of this, MTZ enhanced the glucose-lowering effects of metformin in db/db mice. MTZ is known to be a carbonic anhydrase inhibitor (CAI); however, CAIs acetazolamide, ethoxyzolamide, dichlorphenamide, chlorthalidone, and furosemide were not effective in vivo. Our results demonstrate that MTZ acts as an insulin sensitizer that suppresses hepatic glucose production in vivo. The antidiabetic effect of MTZ does not appear to be a function of its known activity as a CAI. The additive glucose-lowering effect of MTZ together with metformin highlights the potential utility for the management of type 2 diabetes. PMID:22586591

    Betatrophin/ANGPTL8 is a newly identified hormone produced in liver and adipose tissue that has been shown to be induced as a result of insulin resistance and regulates lipid metabolism. Little is known about betatrophin level in humans and its association with T2D and metabolic risk factors. Plasma level of betatrophin was measured by ELISA in 1603 subjects: 1047 non-diabetic and 556 T2D subjects and its associations with metabolic risk factors in both non-diabetic and T2D were also studied. Our data show a significant difference in betatrophin levels between non-diabetic (731.3 (59.5–10625.0) pg/ml) and T2D (1710.5 (197.4–12361.1) p < 0.001. Betatrophin was positively correlated with age, BMI, waist/hip ratio, FBG, HbA1C, HOMA-IR and TG in the non-diabetic subjects. However, no association was observed with BMI, FBG, HbA1C or HOMA-IR in T2D subjects. TC and LDL showed negative association with betatrophin in T2D subjects. Multivariate analysis showed that subjects in the highest tertile of betatrophin had higher odds of having T2D (odd ratio [OR] = 6.15, 95% confidence interval [CI] = (3.15 – 12.01). Our data show strong positive associations between betatrophin and FBG and insulin resistance in non-diabetic subjects. However, correlations with FBG and insulin resistance were diminished in T2D subjects. PMID:26077345

  7. Clinical utility and accuracy of a blood glucose meter for the detection of neonatal hypoglycemia

    International Nuclear Information System (INIS)

    Objective: To determine the accuracy and reliability of a glucometer in comparison to hexokinase method in detecting neonatal hypoglycemia. Subjects and Methods: All neonates presenting with known risk factors or suggestive clinical features were screened for hypoglycemia by using capillary blood on Accutrend alpha glucometer. Simultaneously the venous blood glucose values were done on Hitachi 902 autoanalyser by hexokinase method. A level of 40 mg/dl or less was taken as neonatal hypoglycemia. Results: A total of 292-paired samples were taken from 223 neonates. Hypoglycemia was detected in 112 samples (38.4%). Correlation of glucometer values with laboratory values of blood glucose levels was excellent throughout the range with coefficient of correlation (r) of 0.976 (p-value < 0.001). For blood glucose values equal or less than 40 mg/dl, r was 0.547 (p-value < 0.001). The instrument used showed a sensitivity of 98% and specificity of 93% to detect neonatal hypoglycemia (equal or less than 40 mg/dl) with a positive predictive value of 88% and negative predictive value 99%. Conclusion: The blood glucose reflectance meter can be a useful and accurate instrument for screening and detecting neonatal hypoglycemia in symptomatic babies under stress. All low values by glucometer should be promptly analyzed and confirmed by chemical laboratory. (author)

    Therapeutically, the closed-loop blood glucose-insulin regulation paradigm via a controllable insulin pump offers a potential solution to the management of diabetes. However, the development of such a closed-loop regulatory system to date has been hampered by two main issues: 1) the limited knowledge on the complex human physiological process of glucose-insulin metabolism that prevents a precise modeling of the biological blood glucose control loop; and 2) the vast metabolic biodiversity of the diabetic population due to varying exogneous and endogenous disturbances such as food intake, exercise, stress, and hormonal factors, etc. In addition, current attempts of closed-loop glucose regulatory techniques generally require some form of prior meal announcement and this constitutes a severe limitation to the applicability of such systems. In this paper, we present a novel intelligent insulin schedule based on the pseudo self-evolving cerebellar model articulation controller (PSECMAC) associative learning memory model that emulates the healthy human insulin response to food ingestion. The proposed PSECMAC intelligent insulin schedule requires no prior meal announcement and delivers the necessary insulin dosage based only on the observed blood glucose fluctuations. Using a simulated healthy subject, the proposed PSECMAC insulin schedule is demonstrated to be able to accurately capture the complex human glucose-insulin dynamics and robustly addresses the intraperson metabolic variability. Subsequently, the PSECMAC intelligent insulin schedule is employed on a group of type-1 diabetic patients to regulate their impaired blood glucose levels. Preliminary simulation results are highly encouraging. The work reported in this paper represents a major paradigm shift in the management of diabetes where patient compliance is poor and the need for prior meal announcement under current treatment regimes poses a significant challenge to an active lifestyle.

All patients reported a previous diagnosis of diabetes mellitus, were under 60 years of age, had no hematocrit alterations, remained hemodynamically stable during the time of data collection, and were given no ascorbic acid, acetaminophen, dopamine, or mannitol during follow-up. Capillary and serum blood glucose samples were collected simultaneously by finger-stick and venipuncture 2 hours after lunch, by the same observer, who was blinded to the serum glucose results. First, between July and November 2009, capillary glucose levels were measured using the blood glucose meters OneTouch SureStep® and MediSense Optium®. Between November 2009 and February 2010, capillary blood glucose levels were measured on the glucose meters OneTouch SureStep and Optium Xceed®.

    Full Text Available Background: Hypoglycemia is one of the most common neonatal disorders, associated with severe complications. There has been a great deal of controversy regarding the definition and screening of hypoglycemia. Therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. Methods: This cross-sectional study was conducted on 238 newborns at risk of hypoglycemia, admitted to Baqiyatallah Hospital of Tehran, Iran in 2012; the subjects were selected via simple sampling. After obtaining informed consents from the newborns’ parents, 1 cc blood samples were sent to the laboratory for measuring the blood glucose level. Moreover, venous blood samples, as well as heel-stick blood samples, were obtained for glucometer measurements. Blood glucose measurements were used to determine the cut-off value by the receiver operating characteristic (ROC curve and make comparisons with the diagnostic criteria for hypoglycemia in the literature. Results: A total of 238 infants with the mean weight of 2869±821.9 g were enrolled in this study. The mean (±SD blood glucose levels were 65.1±22.9, 82.9±24.7, and 84.4±24.8 mg/dl, based on the standard laboratory method, glucometer reading of venous blood samples, and glucometer reading of heel-stick capillary blood samples, respectively. The optimal cut-off point for hypoglycemia was determined as 65 mg/dl, using glucometer-based assessment of heel-stick blood samples. Conclusion: The significant difference in blood glucose levels measured by the laboratory method and outpatient glucometer readings highlights the importance of a cut-off value for rapid assessment and control of blood glucose and timely detection of hypoglycemia. In fact, the cut-off value introduced in the present study could facilitate such measurements.

    Tungsten disulfide (WS2) nanosheets were discovered to possess intrinsic peroxidase-like activity and catalyze the peroxidase substrate 3,3',5,5'-tetramethylbenzidine (TMB) to produce a color reaction in the presence of H2O2. Based on this finding, a colorimetric method and a portable test kit for the visual detection of blood glucose have been developed by using glucose oxidase (GOx) and WS2 nanosheets-catalyzed reactions. The linear range for glucose was ranged from 5 to 300 μM (R(2)=0.999) with the detection limit of 2.9 μM. The portable test kit was successfully evaluated glucose levels in serum samples from normal persons and diabetes persons by the observable color change from pale yellow to yellow-green, blue-green.

    The increasing prevalence and risk of complications from diabetes necessitate patient participation and attentiveness to select appropriate foods, perform regular physical activity, and be active in diabetes management and self-maintenance. Diabetes is often largely asymptomatic; consequently, early diagnosis and treatment are necessary. Inmates are a unique population challenged by the increased prevalence of chronic conditions including diabetes. Diabetes standards for inmates contain diagnostic and treatment management guidelines that incorporate personal glucose monitoring for insulin users. In December 2009, the Federal Bureau of Prisons initiated a program to distribute glucose meters to insulin-dependent inmates to facilitate self-monitoring blood glucose. The purpose of this study was to evaluate the effect of these glucose meters on hemoglobin A1c levels. PMID:26276137

    Diabetes is one of the most debilitating and costly diseases currently plaguing humanity. It is a leading cause of death and dismemberment in the world, and we know how to treat it. Accurate, continuous monitoring and control of blood glucose levels via insulin treatments are widely known to mitigate the majority of detrimental effects caused by the disease. The primary limitation of continuous glucose monitoring is patient non-compliance due to the unpleasant nature of "finger-stick" testing methods. This limitation can be largely, or even completely, removed by non-invasive testing methods. In this report, we demonstrate the vibrational overtone circular dichroism properties of glucose and analyze its use as a method of non-invasive glucose monitoring, capable of assuaging this trillion dollar scourge.

    Full Text Available Abstract Background Methamphetamine (METH, an addictive psycho-stimulant drug with euphoric effect is known to cause neurotoxicity due to oxidative stress, dopamine accumulation and glial cell activation. Here we hypothesized that METH-induced interference of glucose uptake and transport at the endothelium can disrupt the energy requirement of the blood-brain barrier (BBB function and integrity. We undertake this study because there is no report of METH effects on glucose uptake and transport across the blood-brain barrier (BBB to date. Results In this study, we demonstrate that METH-induced disruption of glucose uptake by endothelium lead to BBB dysfunction. Our data indicate that a low concentration of METH (20 μM increased the expression of glucose transporter protein-1 (GLUT1 in primary human brain endothelial cell (hBEC, main component of BBB without affecting the glucose uptake. A high concentration of 200 μM of METH decreased both the glucose uptake and GLUT1 protein levels in hBEC culture. Transcription process appeared to regulate the changes in METH-induced GLUT1 expression. METH-induced decrease in GLUT1 protein level was associated with reduction in BBB tight junction protein occludin and zonula occludens-1. Functional assessment of the trans-endothelial electrical resistance of the cell monolayers and permeability of dye tracers in animal model validated the pharmacokinetics and molecular findings that inhibition of glucose uptake by GLUT1 inhibitor cytochalasin B (CB aggravated the METH-induced disruption of the BBB integrity. Application of acetyl-L-carnitine suppressed the effects of METH on glucose uptake and BBB function. Conclusion Our findings suggest that impairment of GLUT1 at the brain endothelium by METH may contribute to energy-associated disruption of tight junction assembly and loss of BBB integrity.

    Full Text Available We examined the tracking of blood glucose, the development of prediabetes, and estimated their genetic contributions in a prospective, healthy, rural Chinese twin cohort. This report includes 1,766 subjects (998 males, 768 females aged 6-21 years at baseline who completed a 6-year follow-up study. Oral glucose tolerance test was performed for all subjects at both baseline and follow-up. We found that subjects with low fasting plasma glucose (FPG or 2 h post-load glucose (PG levels at baseline tended to remain at the low level at follow-up. Subjects in the top tertile of baseline plasma glucose tended to have a higher risk of developing prediabetes at follow-up compared to the low tertile: in males, 37.6% vs. 27.6% for FPG and 37.2% vs. 25.7% for 2hPG, respectively; in females, 31.0% vs. 15.4% for FPG and 28.9% vs. 15.1% for 2 h PG, respectively. Genetic factors explained 43% and 41% of the variance of FPG, and 72% and 47% for impaired fasting glucose for males and females, respectively; environmental factors substantially contribute to 2hPG status and impaired glucose tolerance. In conclusion, in this cohort of healthy rural Chinese children and adolescents, we demonstrated that both FPG and 2hPG tracked well and was a strong predictor of prediabetes. The high proportion of children with top tertile of blood glucose progressed to prediabetes, and the incidence of prediabetes has a male predominance. Genetic factors play more important role in fasting than postload status, most of which was explained by unique environmental factors.

    Abstract Background To examine the blood glucose profile and the relationship between blood glucose levels and neurodevelopmental outcome in term infants with hypoxic-ischaemic encephalopathy. Methods Blood glucose values within 72 hours of birth were collected from 52 term infants with hypoxic-ischaemic encephalopathy. Hypoglycaemia [< 46.8 mg\\/dL (2.6 mmol\\/L)] and hyperglycaemia [> 150 mg\\/dL (8.3 mmol\\/L)] were correlated to neurodevelopmental outcome at 24 months of age. Results Four fifths of the 468 blood samples were in the normoglycaemic range (392\\/468:83.8%). Of the remaining 76 samples, 51.3% were in the hypoglycaemic range and (48.7%) were hyperglycaemic. A quarter of the hypoglycaemic samples (28.2%:11\\/39) and a third of the hyperglycaemic samples (32.4%:12\\/37) were recorded within the first 30 minutes of life. Mean (SD) blood glucose values did not differ between infants with normal and abnormal outcomes [4.89(2.28) mmol\\/L and 5.02(2.35) mmol\\/L, p value = 0.15] respectively. In term infants with hypoxic-ischaemic encephalopathy, early hypoglycaemia (between 0-6 hours of life) was associated with adverse outcome at 24 months of age [OR = 5.8, CI = 1.04-32)]. On multivariate analysis to adjust for grade of HIE this association was not statistically significant. Late hypoglycaemia (6-72 hours of life) was not associated with abnormal outcome [OR = 0.22, CI (0.04-1.14)]. The occurrence of hyperglycaemia was not associated with adverse outcome. Conclusion During the first 72 hours of life, blood glucose profile in infants with hypoxic-ischaemic encephalopathy varies widely despite a management protocol. Early hypoglycaemia (0-6 hours of life) was associated with severe HIE, and thereby; adverse outcome.

    mHeath technologies are recognized to play important roles in the future of personal care and medicine. However, their full potentials have not been reached, as most of current technologies are restricted to monitoring physical and behavioral parameters, such as body temperature, heart rate, blood pressure, and physical movement, while direct monitoring of biomarkers in body fluids can provide much more accurate and useful information for medical diagnostics. A major barrier to realizing the full potential of mHealth is the high costs and long cycles of developing mHealth devices capable of monitoring biomarkers in body fluids. To lower the costs and shorten the developmental cycle, we have demonstrated the leveraging of the most successful portable medical monitoring device on the market, the blood glucose meter (BGM), with FDA-approved smartphone technologies that allow for wireless transmission and remote monitoring of a wide range of non-glucose targets. In this protocol, an aptamer-based assay for quantification of interferon-γ (IFN-γ) using an off-the-shelf BGM is described. In this assay, an aptamer-based target recognition system is employed. When IFN-γ binds to the aptamer, it triggers the release of a reporter enzyme, invertase, which can catalyze the conversion of sucrose (not detected by BGM) to glucose. The glucose being produced is then detected using a BGM. The system mimics a competitive enzyme-linked immunosorbent assay (ELISA), where the traditional immunoassay is replaced by an aptamer binding assay; the reporter protein is replaced by invertase, and finally the optical or fluorescence detector is replaced with widely available BGMs. PMID:25626534

    Full Text Available Objective: The human brain adjusts its level of effort in coping with various life stressors as a partial function of perceived access to social resources. We examined whether people who avoid social ties maintain a higher fasting basal level of glucose in their bloodstream, reflecting a strategy to draw more on personal resources when threatened.Methods: For Study 1, we obtained fasting blood glucose and adult attachment orientations data from 60 undergraduate women at the University of Virginia. For Study 2, we collected measures of fasting blood glucose, self-reported trait anxiety, DHEA-cortisol, hypertension, and adult attachment orientations from 285 older adults of mixed gender, using a measure of attachment style different from study 1.Results: In study 1, fasting blood glucose levels corresponded with higher attachment avoidance scores after statistically adjusting for interpersonal anxiety. For study 2, fasting blood glucose continued to correspond with higher adult attachment avoidance even after statistically adjusting for interpersonal anxiety, trait anxiety, DHEA-cortisol and hypertension. Conclusions: Results suggest socially avoidant individuals upwardly adjust their basal glucose levels with the expectation of increased personal effort because of limited access to social resources.

    Objective: To probe glycemic excursions in type 2 diabetic patients whose hemoglobin A1c (HbA1c) was kept ≤6.0%.Methods: Totally 36 cases with type 2 diabetes (T2DM) with HbA1c≤6.0% and 30 cases with normal glucose tolerance (NGT) from December 2005 to December 2007 in our department were subjected prospectively. Continuous glucose monitoring system (CGMS) was employed to record their continuous blood glucose level for 3 d. The blood glucose profiles including the mean blood glucose (MBG), standard differentiation (SD), mean amplitude of glycemic excursions (MAGE) and absolute means of daily differences (MODD) were analyzed. Results: T2DM group had obviously postprandial hyperglycemia, in about 2 h after meal, especially after breakfast. Fifty-two hypoglycemic episodes occurred during the monitoring period in T2DM groups, of which 73.1% (38 episodes) were absence of symptomatic hypoglycemia with the lowest value of blood glucose only 2.0 mmol/L. And 20 episodes took place during the day hours, while 32 episodes observed during the night hours. Compared with NGT groups, SD, MAGE and MODD were all significantly higher in T2DM groups. MBG was significantly correlated with HbA1c in T2DM groups, but SD, MAGE, NGE and MODD were all independent of HbA1c. MAGE was independent of MODD. Conclusion: The amplitude of glycemic excursions is higher in normol-controlled T2DM groups than the NGT groups.Thus ideally glycemic control is not only to make HbA1c reach standard, but also to lessen glycemic excursions and reduce hypoglycemia episodes.

    Full Text Available Objective  To study the hypoglycemic effect and insulin sensitization mechanism of ophiopogonis tuber extracts on the 3T3-L1-induced adipocytes, and also in rats with reproduction of type 2 diabetes mellitus (T2DM. Methods  3T3-L1 cells were induced and differentiated into adipocytes. After the intervention with ophiopogonpolysaccharide (OPSR and ophiopogonin (OPG, glucose consuming rate was detected for screening the extracts which may have effective hypoglycemic effects. The insulin resistance (IR adipocyte model was established by dexamethasone induction, and then it was treated with OPSR. The protein expression levels of leptin, adiponectin and resistin were detected by Western blotting. The T2DM rat model was reproduced and then treated with OPSR for 4 weeks. Body weight (BW, triglyeride (TG, fasting blood glucose (FBG and fasting insulin (FINs of the rats were measured respectively. Results  OPSR in dosage of 0.5-50mg/L promoted glucose consumption of adipocytes in a dose-dependent manner, the glucose consumption ratios were 32.27%, 75.14% and 90.47% respectively. OPG of 50mg/L showed very weak activity with glucose consumption ratio of only 8.49%. OPSR could significantly promote the protein expression of leptin and adiponectin, and showed an inhibitory effect on the protein expression of resistin (P<0.05. After treatment with OPSR for 4 weeks, the BW of rats increased obviously, while TG, FBG and HOMA-IR decreased significantly (P<0.05 or P<0.01. Conclusions  OPSR may promote glucose transport and utilization of adipocytes, decrease the level of FBG and TG, and improve the condition of IR in T2DM rats. The mechanism of blood glucose lowering effect may be attributed to secretion of adipokines, such as leptin, adiponectin and resistin by IR adipocytes.

    Full Text Available Background: Early and non-invasive determination of blood glucose level is of great importance. We aimed to present a new technique to accurately infer the blood glucose concentration in peripheral blood flow using non-invasive optical monitoring system.Methods: The data for the research were obtained from 900 individuals. Of them, 750 people had diabetes mellitus (DM. The system was designed using a helium neon laser source of 632.8 nm wavelength with 5mW power, photo detectors and digital storage oscilloscope. The laser beam was directed through a single optical fiber to the index finger and the scattered beams were collected by the photo detectors placed circumferentially to the transmitting fiber. The received signals were filtered using band pass filter and finally sent to a digital storage oscilloscope. These signals were then decomposed into approximation and detail coefficients using modified Haar Wavelet Transform. Back propagation neural and radial basis functions were employed for the prediction of blood glucose concentration.Results: The data of 450 patients were randomly used for training, 225 for testing and the rest for validation. The data showed that outputs from radial basis function were nearer to the clinical value. Significant variations could be seen from signals obtained from patients with DM and those without DM.Conclusion: The proposed non-invasive optical glucose monitoring system is able to predict the glucose concentration by proving that there is a definite variation in hematological distribution between patients with DM and those without DM.

The control group (CG had free supply of chow, while the restriction group (RG received 50% of the amount ingested by the CG. The experiments were done in adult (60 days overnight fasted rats in which glycemia, liver free glucose levels and hepatic glycogen concentration were measured. In part of the experiments in situ liver perfusion was done. The results showed that livers from the RG had higher glycogenolysis rates but lower gluconeogenesis rates from L-alanine (10 mM. Since RG showed maintained glycemia during fasting, it could be concluded that livers from RG produced glucose preferentially from glycogenolysis in detriment of gluconeogenesis. These findings demonstrated that in spite of severe caloric restriction, the metabolic adaptations of the liver did exist to assure the maintenance of blood glucose for brain supply during fasting.

    Full Text Available Background & aim: The decrease of serum glucose level and lipids in diabetic patients is clinically significant. The purpose of this study was to determine the effect of Commiphora mukul extract on blood sugar and lipid profile in diabetic rats. Methods: In the present experimental study, thirty-two male Wistar rats were randomly divided into four groups: control, control treated with the extract, diabetic and diabetic treated with the extract. Diabetes was induced by intraperitoneal injection of Streptozotocin. In an eight week period, the control group of normal saline and the control group and diabetic recipient extract of CM oleo gum blue resin was given by gavage. Treatment resumed eight weeks with onset of hyperglycemia. The control and diabetic control groups received normal saline orally. Extract treated control and extract treated diabetic groups received extract of Commiphora mukul gum (300 mg/kg P.O. daily by gavage. At the end of this period, blood samples were collected from each rat and biochemical tests for investigation of glucose level and lipid profile was performed. One- way analysis of variance (ANOVA statistical test and Post-hoc test Tukey’s were used for data analysis Results: The study indicated that diabetes increases the serum levels of glucose, cholesterol, triglycerides, LDL and HDL. Administration of Commiphora mukul gum extract in diabetic groups significantly decreased the serum level of glucose, cholesterol(p<0.01 and triglyceride and LDL(p<0.001 and increased HDL(p<0.01. Conclusion: Commiphora mukul gum extract may well improve undesirable effects of diabetes on serum level of glucose, cholesterol, triglyceride, LDL and HDL.

    Accurate self-monitoring of blood glucose is a key component of effective self-management of glycemic control. The OneTouch VerioFlex(™) (OTVF) blood glucose monitoring system (BGMS) was evaluated for accuracy in a clinical setting. Patients also used OTVF for a 1-wk trial period and reported their level of satisfaction with meter features. In a separate study, healthcare professionals used an on-line simulator of the BGMS and answered questions about its potential utility to their patients. OTVF was accurate over a wide glucose range and met lay user and system accuracy blood glucose standards described in ISO15197:2013 as well as the accuracy requirements to fulfill US FDA expectations for 510(k) clearance of BGMS. Patients and healthcare professionals felt the features of OTVF, which has the capability to connect wirelessly to mobile devices and interact wirelessly with diabetes management software, could provide significant benefits to them or their patients.

    We have expanded a former compartmental model of blood glucose regulation for healthy and type 2 diabetic subjects. The former model was a detailed physiological model which considered the interactions of three substances, glucose, insulin and glucagon on regulating the blood sugar. The main...... drawback of the former model was its restriction on the route of glucose entrance to the body which was limited to the intravenous glucose injection. To handle the oral glucose intake, we have added a model of glucose absorption in the gastrointestinal tract to the former model to address the resultant...... variations of blood glucose concentrations following an oral glucose intake. Another model representing the incretins production in the gastrointestinal tract along with their hormonal effects on boosting pancreatic insulin production is also added to the former model. We have used two sets of clinical data...

    Recently, zebrafish have been used to examine hyperglycemia-induced complications (retinopathy and neuropathy), as would occur in individuals with diabetes. Current models to induce hyperglycemia in zebrafish include glucose immersion and streptozotocin injections. Both are effective, although neither is reported to elevate blood sugar values for more than 1 month. In this article, we report differences in hyperglycemia induction and maintenance in young (4-11 months) versus old (1-3 years) zebrafish adults. In particular, older fish immersed in an alternating constant external glucose solution (2%) for 2 months displayed elevated blood glucose levels for the entire experimental duration. In contrast, younger adults displayed only transient hyperglycemia, suggesting the fish were acclimating to the glucose exposure protocol. However, modifying the immersion protocol to include a stepwise increasing glucose concentration (from 1% → 2%→3%) resulted in maintained hyperglycemia in younger zebrafish adults for up to 2 months. Glucose-exposed younger fish collected after 8 weeks of exposure also displayed a significant decrease in wet weight. Taken together, these data suggest different susceptibilities to hyperglycemia in older and younger fish and that stepwise increasing glucose concentrations of 1% are required for maintenance of hyperglycemia in younger adults, with higher concentrations of glucose resulting in greater increases in blood sugar values.

    Complementary and alternative therapies in addition to standard oncology protocols are commonly sought by cancer patients; however, few patients disclose their complementary treatments to their cancer care team. A lack of communication may result in unforeseen side effects and the potential for some alternative therapies to interfere with or inhibit conventional treatment. High-dose vitamin C therapy, in particular, may lead to an inability to measure a patient's blood glucose level before (18)F-FDG injection for PET/CT scanning. We report a case of a 52-y-old woman referred for (18)F-FDG PET/CT to evaluate the extent of recurrent colorectal cancer. The PET/CT scan immediately followed a single intravenous dose of 25 g of ascorbic acid from her naturopath. A glucometer that applies the glucose oxidase method for measuring fasting blood glucose was used, for which high doses of vitamin C are listed as a contraindication. The high concentration of ascorbic acid in the patient's blood sample interfered with the chemical reaction on the glucose strip, and therefore no blood glucose measurement could be attained. With more patients receiving alternative and complementary cancer therapies, it is important to know what the implications of orthomolecular therapy might be on routine blood glucose testing for (18)F-FDG PET scans. (18)F-FDG is in direct competition with glucose; therefore, elevated blood glucose levels will cause a decrease in (18)F-FDG absorption and may lead to a false-negative scan. PMID:25104819

    In this paper, the propagation characteristics of near-infrared (NIR) light in the palm tissue are analyzed,and the principle and feasibility of using transcutaneous diffuse reflectance spectroscopy for non-invasive blood glucose detection are presented. An optical probe suitable for measuring the diffuse reflectance spectrum of human palm and a non-invasive blood glucose detection system using NIR spectroscopy are designed. Based on this system, oral glucose tolerance tests are performed to measure the blood glucose concentrations of two young healthy volunteers. The partial least square calibration model is then constructed by all individual experimental data. The final result shows that correlation coefficients of the two experiments between the predicted blood glucose concentrations and the reference blood glucose concentrations are 0.9870 and 0.9854, respectively. The root mean square errors of prediction of full cross validation are 0.54 and 0.52 mmol/1, respectively.

    Cognitive functioning was assessed in diabetic patients during hypoglycemia (60 mg/dl), euglycemia/control (110 mg/dl), and hyperglycemia (300 mg/dl). Blood glucose levels were set and maintained to within 4% of targeted levels by an artificial insulin/glucose infusion system (Biostator). Attention and fine motor skills, assessed by visual reaction time, was slowed at altered glucose levels. Performance was less impaired during hyperglycemia than hypoglycemia when a longer interstimulus interval was used, although it was still slower than normal. The time required to solve simple addition problems was increased during hypoglycemia, although reading comprehension was not affected. The possibility that some automatic brain skills are disrupted at altered glucose concentrations is discussed, while associative or inferential skills may be less affected.

    Background Previous studies have demonstrated that serum uric acid (UA) is an independent predictor of incident type 2 diabetes mellitus (T2DM) in general populations. This study aimed to investigate specific characteristics of UA and its relationship between UA and blood glucose and other risk factors in the Chinese population.Methods A total of 946 subjects were included in this study. UA, glucose, insulin, fractional excretion of UA (FEua),creatinine clearance rate (Ccr), hemoglobin A1c (HbA1c), fructosamine (FA), blood pressure and lipids were studied and also reexamined after the patients underwent two weeks of combined therapeutics.Results UA levels were the highest in subjects with impaired glucose regulation (IGR), followed by subjects with normoglycemia (NGT) and finally by subjects with T2DM. The level of the 2-hour postprandial insulin and the area under the curve for insulin (AUCins) showed a similar tendency. The UA levels initially increased with increasing fasting blood glucose (FBG) and postprandial blood glucose (PPBG) levels, up to 7 mmol/L and 10 mmol/L, respectively, and thereafter decreased at higher FBG and PPBG levels. Compared with subjects in the lower serum UA quartile, subjects in the upper quartile of serum UA levels had higher weights, triglyceride levels, and creatinine levels as well as lower Ccr and FEua levels. Compared with women's group, UA levels were higher, and FEua levels were lower in men's group. Sex,body mass index (BMI), mean arterial blood pressure (MAP), serum triglycerides (TG), FA and Ccr were independent correlation factors of UA. UA decreased and FEua increased after the patients underwent a combined treatment.Conclusions UA increased initially and then decreased as glucose levels increased from NGT to IGR and T2DM.Compared with NGT and T2DM, IGR subjects had higher SUA levels, which related to its high levels of insulin. Under T2DM, male gender, BMI, MAP, Ccr, TG and FA are independent correlation factors of UA

    Full Text Available Background: Diabetes is an important disease. This disease is a metabolic disorder characterized by hyperglycemia resulting from perturbation in insulin secretion, insulin action or both. Honey bee venom contains a wide range of polypeptide agents. The principle components of bee venom are mellitin and phospholipase A2. These components increase insulin secretion from the β-cells of pancreas. This study was conducted to show the hypoglycemic effect of honey bee venom on alloxan induced diabetic male rats.Methods: Eighteen adult male rats weighting 200±20 g were placed into 3 randomly groups: control, alloxan monohy­drate-induced diabetic rat and treated group that received honey bee venom daily before their nutrition for four months. Forty eight hours after the last injection, blood was collected from their heart, serum was dissented and blood glucose, insulin, triglyceride and total cholesterol were determined.Results: Glucose serum, triglyceride and total cholesterol level in treated group in comparison with diabetic group was significantly decreased (P< 0.01. On the other hand, using bee venom causes increase in insulin serum in com­parison with diabetic group (P< 0.05.Conclusion: Honeybee venom (apitoxin can be used as therapeutic option to lower blood glucose and lipids in dia­betic rats.

    The goals of the present study were to determine whether the infusion of a glucose solution into the portal vein is tolerated in cows and whether the glucose concentration differs after administration of glucose into the jugular vein and portal vein. Fifteen healthy Swiss Braunvieh cows were used. An indwelling catheter was placed in both jugular veins and a balloon-tipped indwelling catheter with a diameter of 2 mm was placed in the portal vein under the guidance of ultrasonography. Three cows received 500 ml of 20% glucose solution over 60 min via the left jugular vein. Three other cows received the same solution over 60 min via the portal vein. Blood samples were collected from the right jugular vein before and for 24 h after the infusion of glucose for the determination of the concentrations of glucose and bilirubin and the activities of glutamate dehydrogenase, sorbitol dehydrogenase and gamma-glutamyl transferase. Infusion via the portal vein did not result in abnormalities in the general condition of the cows or increases in the concentration of bilirubin or the activities of liver enzymes. The blood glucose concentration increased to the same extent after both intraportal and intrajugular infusion. Over a 12-h period, three cows received 10 l of 20% glucose solution via the left jugular vein and three others received the same solution over a 12-h period via the portal vein. Blood samples were collected from the right jugular vein before and for 30 h after the start of infusion. Infusion via the portal vein did not affect the general condition of the cows or the activities of the liver enzymes. There was no significant difference in the blood glucose concentration between the two groups throughout the study.

    In this study we generated a simple, reliable and selective approach based on carbon dots (CDs) and 4-cyanophenylboronic acid (CPBA) for blood glucose sensing. The methodology relies on the quenching of the emission of CDs by CPBA followed by its recovery by glucose. The system consisting of CDs and CPBA was characterised by Fourier transform infra red spectrum, transmissions electron microscopic, dynamic light scattering instrument, UV–visible and fluorescence techniques. The response of the probe, CD-BA in presence of different concentrations of glucose was assessed. Linear range was obtained for glucose concentrations ranging from 1 to 30 mM. Interferences by other saccharides and various biomolecules coexisting in blood serum were negligible. The chemo sensor thus developed has been successfully used for the estimation of glucose in human blood serum. The system being sensitive, efficient and easy to perform is a promising platform for blood glucose sensing.

    Tear glucose sensing for diabetes management has long been sought as an alternative to more invasive self-monitoring of blood glucose (SMBG). However, tear glucose sensors were known to have limitations, including correlation issues with blood glucose due to low sample volume, low concentration of glucose in the tear fluid, and evaporation of the tear sample. An engineering design approach to solve these problems led to the development of an integrated device capable of collecting the tear sample from the ocular surface with little to no stress on the eye, with an extremely low limit of detection, broad dynamic range, and rapid detection and analysis of sample. Here we present the development of a prototypical self-monitoring of tear glucose (SMTG) sensor, summarizing bench studies on the enzymes and their specificity, the development of the fluid capture device and its manufacture and performance and results of system testing in an animal study where safety, lag time and tear glucose to blood glucose correlation were assessed.

    Objective To observe the changes of plasma glucose level (PGL) in human volunteers after acupuncture. Methods Seventy-seven human volunteers were taken up from the acupuncture clinic. All of pletion of acupuncture. All cases were at four hours abstinence from food before doing acupuncture. Results Plasma glucose level varied 5 mg% or more in 62 cases (80.51%) and only those were considered for computation. PGL increased in cases who had generally plasma glucose level below 90 mg% before acupuncture;and PGL decreased in cases who had plasma glucose 90 mg% or above. In 10 control cases there was no variation of the considerable level of 5 mg% in any case. Conclusion Bi-directional variation of PGL after acupuncture indicates that acupuncture can be used to maintain optimum PGL through endogenous mechanism,suggesting that it is applicable in controlling hyperglycemia in diabetes mellitus patients.

    Despite the significant value of the southeastern United States' red drum (Sciaenops ocellatus) fishery, there is a lack of clinical blood chemistry data. This was the first study to assess plasma glucose values as an indicator of stress response to evaluate variation and the effect of reproductive activity for wild adult red drum in Florida. Red drum (n=126) were collected from NASA's Kennedy Space Center waters during three reproductive periods in 2011. Samples were obtained from the branchial vessels of the gill arch. Plasma glucose levels were significantly different among reproductive periods, with the highest mean values recorded during the spawning period, September- October (38.23 mg / dL +/- 10.0). The glucose range was 17 - 69 mg / dL. Glucose values were lower during all three periods than previous values recorded for cultured or captive red drum studies. This may indicate that fish from this population were under less stress than other populations previously sampled.

    We investigated the effect of curcumin on insulin resistance and glucose homeostasis in male C57BL/KsJ-db/db mice and their age-matched lean non-diabetic db/+ mice. Both db/+ and db/db mice were fed with or without curcumin (0.02%, wt/wt) for 6 wks. Curcumin significantly lowered blood glucose and HbA 1c levels, and it suppressed body weight loss in db/db mice. Curcumin improved homeostasis model assessment of insulin resistance and glucose tolerance, and elevated the plasma insulin level in db/db mice. Hepatic glucokinase activity was significantly higher in the curcumin-supplemented db/db group than in the db/db group, whereas glucose-6-phosphatase and phosphoenolpyruvate carboxykinase activities were significantly lower. In db/db mice, curcumin significantly lowered the hepatic activities of fatty acid synthase, beta-oxidation, 3-hydroxy-3-methylglutaryl coenzyme reductase, and acyl-CoA: cholesterol acyltransferase. Curcumin significantly lowered plasma free fatty acid, cholesterol, and triglyceride concentrations and increased the hepatic glycogen and skeletal muscle lipoprotein lipase in db/db mice. Curcumin normalized erythrocyte and hepatic antioxidant enzyme activities (superoxide dismutase, catalase, gluthathione peroxidase) in db/db mice that resulted in a significant reduction in lipid peroxidation. However, curcumin showed no effect on the blood glucose, plasma insulin, and glucose regulating enzyme activities in db/+ mice. These results suggest that curcumin seemed to be a potential glucose-lowering agent and antioxidant in type 2 diabetic db/db mice, but had no affect in non-diabetic db/+ mice.

    demonstrated that a hormone involved in postprandial glucose regulation also limits glucose delivery to brain tissue and hence provides a possible regulatory mechanism for the link between plasma glucose and brain glucose. Because GLP-1 reduces glucose uptake across the intact blood-brain barrier at normal...... glycemia, GLP-1 may also protect the brain by limiting intracerebral glucose fluctuation when plasma glucose is increased.......OBJECTIVE: Glucagon-like peptide-1 (GLP-1) has many effects on glucose homeostasis, and GLP-1 receptors are broadly represented in many tissues including the brain. Recent research in rodents suggests a protective effect of GLP-1 on brain tissue. The mechanism is unknown. We therefore tested...

    In this study, a portable type HMS (Health Monitoring System) device is newly developed. It has features 1) puncturing a blood vessel by using a minimally invasive micro-needle, 2) extracting and transferring human blood and 3) measuring blood glucose level. This miniature SMBG (Self-Monitoring of Blood Glucose) device employs a syringe reciprocal blood extraction system equipped with an electro-mechanical control unit for accurate and steady operations. The device consists of a) a disposable syringe unit, b) a non-disposable body unit, and c) a glucose enzyme sensor. The syringe unit consists of a syringe itself, its cover, a piston and a titanium alloy micro-needle, whose inner diameter is about 100µm. The body unit consists of a linear driven-type stepping motor, a piston jig, which connects directly to the shaft of the stepping motor, and a syringe jig, which is driven by combining with the piston jig and slider, which fixes the syringe jig. The required thrust to drive the slider is designed to be greater than the value of the blood extraction force. Because of this driving mechanism, the automatic blood extraction and discharging processes are completed by only one linear driven-type stepping motor. The experimental results using our miniature SMBG device was confirmed to output more than 90% volumetric efficiency under the driving speed of the piston, 1.0mm/s. Further, the blood sugar level was measured successfully by using the glucose enzyme sensor.

    Noninvasive monitoring of tissue optical properties in real time could significantly improve diagnostics and management of various diseases. Recently we proposed to use high- resolution Optical Coherence Tomography (OCT) technique for measurement of tissue scattering coefficient at the depth of up to 1mm. Our pilot studies performed in vitro and in vivo demonstrated that measurement of tissue scattering with this technique can potentially be applied for noninvasive monitoring of blood glucose concentration. High resolution and coherent photon detection of the OCT technique allowed detection of glucose-induced changes in the scattering coefficient. In this paper we report results of in vivo studies performed in dog, New Zealand rabbits, and first human subjects. OCT system with the wavelength of 1300 nm was used in our experiments. OCT signal slope was measured and compared with actual blood glucose concentration. Bolus glucose injections and glucose clamping administrations were used in animal studies. OCT signals were recorded form human subjects during oral glucose tolerance test. Results obtained form both animal and human studies show good correlation between slope of the OCT signals and actual blood glucose concentration measured using standard glucometesr. Sensitivity and accuracy of blood glucose concentrations monitoring with the OCT is discussed. Obtained result suggest that OCT is a promising technique for noninvasive monitoring of tissue analytes including glucose.

    1989-06-01

    To determine whether ingestion of sucrose-containing snacks would affect blood glucose (BG) control, 16 subjects with insulin-dependent diabetes mellitus participated in a 5-day double-blind study at a diabetes camp. Eight subjects in the sucrose group ate sucrose-sweetened snacks twice a day, and 8 subjects in the control group ingested snacks that were sweetened with aspartame. The percentage of total daily calories derived from added sucrose was 7% for the sucrose group and 1% for the control group. Metabolic control was assessed by daily capillary BG measurements obtained before meals and the bedtime snack and by determination of serum fructosamine (F) concentrations on arrival at camp (day 0) and after 5 days on the study protocol (day 5). No significant difference was seen between the groups on day 0 (sucrose group [mean +/- SD]: BG 9.9 +/- 3.6 mM, F 3.54 +/- 0.38 mM; control group: BG 9.1 +/- 2.8 mM, F 3.74 +/- 0.71 mM) or day 5 (sucrose group: BG 8.8 +/- 2.6 mM, F 2.94 +/- 0.32 mM; control group: BG 7.4 +/- 2.8 mM, F 2.92 +/- 0.59 mM). We conclude that ingestion of sucrose, added to snacks in an amount up to 7% of total energy intake, does not adversely affect short-term BG control. PMID:2659302

Fifty healthy non-diabetic people without endocrine disease were chosen as controls. Glucose, and thyroid hormones, thyroxine and triiodothyronine (total T4 and T3) and thyroid stimulating hormone (TSH) were measured. In addition hemoglobin (Hb), total cholesterol (TC), triglyceride (TG), high-density lipoproteins (HDL) were also measured in both groups. Low-density lipoprotein (LDL) was calculated for each sample. Physical examinations such as height, weight, and history of diabetes, family history, treatment were recorded in both groups. Determination of serum hormones concentration was carried out using highly sensitive RIA technique. While determination of blood glucose, hemoglobin, and lipid profile was carried out using enzymatic colorimetric method. The results of this study showed that: 13 patients of the population screened had thyroid disease. The commonest diagnosis was sub clinical hyperthyroidism (6%), followed by sub clinical hypothyroidism (5%) and hyperthyroidism (2%). Female patients with diabetes had the highest annual risk of developing thyroid disease but all patient groups had a

    Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group. Fasting serum glucose also showed a bit stronger positive correlation with BMI. Both obese male and female persons showed higher levels of fasting serum glucose and glycosylated hemoglobin. The observed positive correlation between BMI with fasting serum glucose and

    In this review, we have discussed the potential application of the emerging imaging modality, i.e., optical coherence tomography (OCT) for glucose monitoring in biological tissues. OCT provides monitoring of glucose diffusion in different fibrous tissues like in sclera by determining the permeability rate with acceptable accuracy both in type 1 and in type 2 diabetes. The maximum precision of glucose measurement in Intralipid suspensions, for example, with the OCT technique yields the accuracy up to 4.4 mM for 10 % Intralipid and 2.2 mM for 3 % Intralipid.

    In the present study serum glucose were estimated in pregnant women during the first trimester of pregnancy and third trimester of pregnancy to observe the frequency of hyperglycemia during pregnancy and to assess the incidence of gestational diabetes mellitus. This study was a cross sectional study, carried out in the Department of Physiology of Mymensingh Medical College, Mymensingh from July 2014 to June 2015. For this purpose, total 300 women with age ranged from 18 to 35 years were selected and divided into 100 healthy non pregnant women as control group and 200 normal pregnant women as study group. Study group was further divided into 100 pregnant women in first trimester of pregnancy and 100 pregnant women in third trimester of pregnancy. Diagnosed case of type I and type II diabetes, hypothyroidism, cushing's syndrome, polycystic ovary, antipsychotic drug users, regular steroid users were excluded from this study. Serum glucose was evaluated by the glucose-oxidase principle by GOD-PAP method in women with 1st trimester of pregnancy, 3rd trimester of pregnancy and in non pregnant women. Statistical analysis of data was done by unpaired student's t test. The results showed that the serum glucose levels increased significantly in third trimester and the value is not significant in first trimester. The increasing frequency of serum glucose level in third trimester may predispose the women to hyperglycemia of pregnancy or gestational diabetes mellitus. PMID:27277349

    Full Text Available Recognition and control of depression symptoms are important to increase patient compliance with treatment and to improve the quality of life of diabetic patients. Clinical studies indicate that selective serotonin reuptake inhibitors (SSRI are better antidepressants for diabetic patients than other drugs. However, preclinical trials have demonstrated that not all SSRI reduce plasma glucose levels. In fact, fluoxetine increases and sertraline decreases glycemia in diabetic and non-diabetic rats. In the present study we evaluated plasma insulin levels during fasting and after glucose overload after treatment with sertraline. Adult male Wistar rats were fasted and treated with saline or 30 mg/kg sertraline and submitted or not to glucose overload (N = 10. Blood was collected and plasma insulin was measured. The mean insulin levels were: fasting group: 25.9 ± 3.86, sertraline + fasting group: 31.10 ± 2.48, overload group: 34.1 ± 3.40, and overload + sertraline group: 43.73 ± 5.14 µU/ml. Insulinemia was significantly increased in the overload + sertraline group. There were no differences between the other groups. No difference in glucose/insulin ratios could be detected between groups. The overload + sertraline group was the only one in which a significant number of individuals exceeded the upper confidence limit of insulin levels. This study demonstrates that sertraline increases glucose-stimulated insulin secretion without any change in peripheral insulin sensitivity.

    It is well known that, in children with type 1 diabetes, metabolic control often deteriorates during puberty. Better understanding of the mechanisms that cause deterioration of blood glucose control can lead to improved therapeutic approaches. Preliminary observations suggest that one component of the impaired glycemic control is a large variation in blood glucose. Several of the hormonal changes during puberty affect insulin sensitivity and could, in addition to lifestyle f...

    Full Text Available Metabolic disorders can cause dizziness. AIM: to study the prevalence of glucose and glucose-insulin alterations in patients with peripheral vestibular disorders by studying the four-hour glucose-insulin curve; to check at what time there was the highest prevalence of altered cases and whether the glucose and insulin curves together are better than the isolate glucose curve and fasting glucose curve. MATERIALS AND METHODS: retrospective study, analyzing 81 four-hour glucose-insulin curves in patients with peripheral vestibular dizziness. RESULTS: Four-hour glucose-insulin curve alterations happened in 87.7% of the patients. Hypoglycemia was seen in 61.7% of the cases, hyperinsulinemia in 55.5%, hyperglycemia in 27.2%, glucose intolerance in 12.3% and hypoinsulinemia in 1.2%. Normal tests were seen in 12.3 % of the cases and altered fasting glucose in 23.5%. CONCLUSIONS: The four-hour glucose-insulin curve analysis showed that 87.7% of the patients with dizziness and suspicion of peripheral vestibular disorder had glucose or insulin metabolism disorders. The highest number of alterations was seen up to the third and fourth hour of the glucose-insulin curve. The glucose and insulin curves together overcame the glucose curve alone and fasting glucose curve in regards of the prevalence of altered cases.Alterações metabólicas podem causar tontura.

    Chronic metabolic alkalosis was induced in rats by combining a low K+ diet with a 0.2 M NaHCO3 solution as drinking fluid for either 15 or 27 days. Local cerebral blood flow and local cerebral glucose utilization were measured in 31 different structures of the brain in conscious animals by means of the iodo-(14C)antipyrine and 2-(14C)deoxy-D-glucose method. The treatment induced moderate (15 days, base excess (BE) 16 mM) to severe (27 days, BE 25 mM) hypochloremic metabolic alkalosis and K+ depletion. During moderate metabolic alkalosis no change in cerebral glucose utilization and blood flow was detectable in most brain structures when compared with controls. Cerebrospinal fluid (CSF) K+ and H+ concentrations were significantly decreased. During severe hypochloremic alkalosis, cerebral blood flow was decreased by 19% and cerebral glucose utilization by 24% when compared with the control values. The decrease in cerebral blood flow during severe metabolic alkalosis is attributed mainly to the decreased cerebral metabolism and to a lesser extent to a further decrease of the CSF H+ concentration. CSF K+ concentration was not further decreased. The results show an unaltered cerebral blood flow and glucose utilization together with a decrease in CSF H+ and K+ concentrations at moderate metabolic alkalosis and a decrease in cerebral blood flow and glucose utilization together with a further decreased CSF H+ concentration at severe metabolic alkalosis.

    Full Text Available Purpose: The aim of this study was to assess the effects of zinc supplementation on anthropometric measures, improving lipid profile biomarkers, and fasting blood glucose level in obese people. Methods: This randomized, double- blind clinical trial was carried out on 60 obese participants in the 18-45 age range for one month. The participants were randomly divided into the intervention group, who received 30 mg/d zinc gluconate, and the placebo group who received 30mg/d starch. Anthropometric measurements (body mass index (BMI, weight and waist circumference were recorded before and at the end of study. Lipid profile biomarkers and fasting blood glucose were determined using enzymatic procedure. Analysis of Covariance (ANCOVA test was run to compare the post-treatment values of the two groups, and t-test was conducted to compare within group changes. Results: Serum zinc concentration was increased significantly in intervention group (p=0.024. BMI and body weight was significantly decreased (p=0.030 and p=0.020, respectively. Lipid profile biomarkers and fating blood glucose did not change significantly but triglyceride level was significantly decreased (p=0.006 in the intervention group. Conclusion: The obtained results indicate that zinc supplementation improves BMI, body weight, and triglyceride concentration without considerable effects on lipid profile and glucose level. Zinc can be suggested as a suitable supplementation therapy for obese people, but more studies are needed to verify the results.

    This study was designed to investigate the effects of physical conditioning on the expression of the insulin sensitive glucose transporter-4 protein (GLUT4) on mononuclear cells and HOMA-IR levels in dogs and compared to results reported in human skeletal muscle and the skeletal muscle of rodent models. Blood was sampled from conditioned dogs (n = 8) and sedentary dogs (n = 8). The conditioned dogs were exercised four months prior the experiment and were following a uniform training protocol, whereas the sedentary dogs were not. GLUT4 expression in mononuclear cells and plasma insulin levels were measured using commercially available enzyme-linked immunosorbent assay (ELISA). Blood glucose levels were determined using blood plasma. HOMA-IR was calculated using plasma insulin and blood glucose levels using the linear approximation formula. Our results indicate that the state of conditioning had a significant effect on the GLUT4 expression at the surface of mononuclear cells. HOMA-IR was also affected by conditioning in dogs. GLUT4 levels in mononuclear cells of sled dogs were inversely correlated with the homeostasis model assessment of insulin sensitivity. This study demonstrates that conditioning increases GLUT4 levels in mononuclear cells of sled dogs as it has been previously reported in skeletal muscle. Our results support the potential of white blood cells as a proxy tissue for studying insulin signaling and may lead to development of a minimally invasive and direct marker of insulin resistance. This may be the first report of GLUT4 in mononuclear cells in response to exercise and measured with ELISA.

    Objective:To explore the relationship between levels of blood glucose, blood lipid and serum cystatin C and lower-extremity arterial disease in type 2 diabetic mellitus so as to provide the basis for the prevention and treatment of the disease.Methods:A total of 240 cases of patients with type 2 diabetic mellitus receiving physical examinations in our hospital from March 2014 to March 2015 were selected and divided into three groups. The control group was consisted of type 2 diabetes patients without lower-extremity arterial disease, the observation group 1 included type 2 diabetes patients with mild or moderate lower-extremity arterial disease, and the observation group 2 was formed by type 2 diabetes patients with severe lower-extremity arterial disease. Each group contained 80 cases. Then, the heights, weights, waist and hip circumferences of patients in the three groups were determined and the body mass index (BMI) and waist to hip ratio (WHR) were calculated; the fasting blood glucose (FBG), fasting insulin (FINS), insulin resistance index (HOMA-IR), 2 h postprandial blood glucose (2 h PG) and glycosylated hemoglobin (HBA1c) in two groups were detected; and the levels of serum total cholesterol(TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (apoA1), apolipoprotein B (apoB) and cystatin C (CysC) in two groups were also tested.Results:Compared with the control group, the WHR, FBG, HOMA-IR, 2 h PG, HBA1c, LDL-C, apoB and CysC all increased significantly, and the differences were statistically significant. Besides, there were statistically significances existing between the observation groups 1 and 2. What’s more, the serum levels of TC, HDL-C, TG and apoA1 in the observation groups were not significantly different from those of the control group.Conclusions: There is a close relationship between blood glucose, blood lipid, serum cystatin C level and lower-extremity arterial

    We tested a dietary supplement formulated with a synergistic combination of vitamins, minerals, herbals in a group of 15 patients with uncontrolled diabetes type II. The supplement was given for 30 days. Fasting blood glucose was measured prior to the supplementation and at the end of the 30 days treatment period. Blood glucose was significantly reduced in all patients with no adverse effects. This orthomolecular correction of faulty glucose metabolism with a combination of nontoxic, safe and fairly inexpensive nutraceuticals needs to be further substantiated. Nervertheless the idea of correcting metabolism with micronutrients is a new concept of genetic nutritioneering that seems appealing and cost effective. PMID:15377060

    Non-invasive blood glucose determination has been investigated by more than 100 research groups in the world during the past fifteen years. The commonly optical methods are based on the capacity of near-IR light to penetrate a few hundreds micrometers or a few millimeters into human tissue where it interacts with glucose. A change of glucose concentration may modify the optical parameters in tissue, with the result that its glucose concentration can be extracted by analyzing the received optical signals. This paper demonstrates that glucose affects on the scattering coefficient of human blood, by applying the streak camera and pulsed photoacoustic techniques; and drinking water seems also affecting on PA signal from skin surface.

    In this study, a new HMS (Health Monitoring System) device is developed for diabetic patient. This device mainly consists of I) 3D blood vessel searching unit and II) automatic blood glucose measurement (ABGM) unit. This device has features such as 1)3D blood vessel location search 2) laptop type, 3) puncturing a blood vessel by using a minimally invasive micro-needle, 4) very little blood sampling (10μl), and 5) automatic blood extraction and blood glucose measurement. In this study, ABGM unit is described in detail. It employs a syringe type's blood extraction mechanism because of its high accuracy. And it consists of the syringe component and the driving component. The syringe component consists of a syringe itself, a piston, a magnet, a ratchet and a micro-needle whose inner diameter is about 80μm. And the syringe component is disposable. The driving component consists of body parts, a linear stepping motor, a glucose enzyme sensor and a slider for accurate positioning control. The driving component has the all-in-one mechanism with a glucose enzyme sensor for compact size and stable blood transfer. On designing, required thrust force to drive the slider is designed to be greater than the value of the blood extraction force. Further, only one linear stepping motor is employed for blood extraction and transportation processes. The experimental result showed more than 80% of volume ratio under the piston speed 2.4mm/s. Further, the blood glucose was measured successfully by using the prototype unit. Finally, the availability of our ABGM unit was confirmed.

  14. Measurement of tissue optical properties with optical coherence tomography: Implication for noninvasive blood glucose concentration monitoring

    Larin, Kirill V.

    Approximately 14 million people in the USA and more than 140 million people worldwide suffer from diabetes mellitus. The current glucose sensing technique involves a finger puncture several times a day to obtain a droplet of blood for analysis. There have been enormous efforts by many scientific groups and companies to quantify glucose concentration noninvasively using different optical techniques. However, these techniques face limitations associated with low sensitivity, accuracy, and insufficient specificity of glucose concentrations over a physiological range. Optical coherence tomography (OCT), a new technology, is being applied for noninvasive imaging in tissues with high resolution. OCT utilizes sensitive detection of photons coherently scattered from tissue. The high resolution of this technique allows for exceptionally accurate measurement of tissue scattering from a specific layer of skin compared with other optical techniques and, therefore, may provide noninvasive and continuous monitoring of blood glucose concentration with high accuracy. In this dissertation work I experimentally and theoretically investigate feasibility of noninvasive, real-time, sensitive, and specific monitoring of blood glucose concentration using an OCT-based biosensor. The studies were performed in scattering media with stable optical properties (aqueous suspensions of polystyrene microspheres and milk), animals (New Zealand white rabbits and Yucatan micropigs), and normal subjects (during oral glucose tolerance tests). The results of these studies demonstrated: (1) capability of the OCT technique to detect changes in scattering coefficient with the accuracy of about 1.5%; (2) a sharp and linear decrease of the OCT signal slope in the dermis with the increase of blood glucose concentration; (3) the change in the OCT signal slope measured during bolus glucose injection experiments (characterized by a sharp increase of blood glucose concentration) is higher than that measured in

    Objective To discuss whether the capillary whole blood glucose (CBG) test can be used in glucose screening test (GST) for gestational diabetes mellitus (GDM) compared to the venous plasma glucose (VPG) method, and to determine the cutoff value of CBG. Methods This was a self-control test. The 50-g oral GST was conducted among 1 557 pregnant women between 24-28 weeks. Every woman was measured CBG and VPG at the same time and same arm. Three hundred and forty women underwent 100-g 3-h oral glucose tolerance test (OGTT). Receiver operation curve (ROC) was used to determine the potential cutoff level of CBG and VPG. Diagnose criteria of GDM was based on NDDG criteria. OGTT diagnosed GDM and VPG ≥ 7. 8 mmol/L were used as golden standard for ROC. Results There was good relationship between CBG and VPG ( P < 0.01 ). Correlation coefficient was 0. 86. The value of CBG was lower than VPG. The statistical and high-sensitivity cutoff values were 7. 4 mmol/L in CBG and 7. 8 mmol/L in VPG when GDM was used as golden standard. Cutoff value of CBG was 7. 0 mmol/L when VPG≥ 7. 8 mmol/L was used as golden standard. The pregnant outcomes of positive cases of three thresholds had no significant differences. But it was better in case of the pregnant woman when the CBG value was more than 7. 4 mmol/L. Conclusion CBG can be used in GST, the threshold of CBG was suggested as 7. 4 mmol/L. CBG test was more convenience and effective than VPG test.

    Optical sensing of glucose would allow more frequent monitoring and tighter glucose control for people with diabetes. The key to a successful optical noninvasive measurement of glucose is the collection of an optical spectrum with a very high signal-to-noise ratio in a spectral region with significant glucose absorption. Unfortunately, the optical throughput of skin is low due to absorption and scattering. To overcome these difficulties, we have developed a high-brightness tunable laser system for measurements in the 2.0-2.5 microm wavelength range. The system is based on a 2.3 microm wavelength, strained quantum-well laser diode incorporating GaInAsSb wells and AlGaAsSb barrier and cladding layers. Wavelength control is provided by coupling the laser diode to an external cavity that includes an acousto-optic tunable filter. Tuning ranges of greater than 110 nm have been obtained. Because the tunable filter has no moving parts, scans can be completed very quickly, typically in less than 10 ms. We describe the performance of the present laser system and avenues for extending the tuning range beyond 400 nm. PMID:16390586

    Full Text Available Objective: To evaluate diabetes patients’ self-monitoring of blood glucose using a community pharmacy-based quality assurance procedure, to investigate whether the procedure improved the quality of the patient performance of self monitoring of blood glucose, and to examine the opinions of the patients taking part in the study. Methods: The results of patient blood glucose measurements were compared to the results obtained with HemoCue Glucose 201+ by pharmacy employees in 16 Norwegian community pharmacies. Patient performance was monitored using an eight item checklist. Patients whose blood glucose measurements differed from pharmacy measurements by more than 20% were instructed in the correct use of their glucometer. The patients then re-measured their blood glucose. If the results were still outside the set limits, the control procedure was repeated with a new lot of glucometer strips, and then with a new glucometer. The patients returned for a follow-up visit after three months. Results: During the first visit, 5% of the 338 patients had measurements that deviated from pharmacy blood glucose values by more than 20% and user errors were observed for 50% of the patients. At the second visit, there was no significant change in the analytical quality of patient measurements, but the percentage of patients who made user errors had decreased to 29% (p < 0.001. Eighty-five percent of the patients reported that they used their blood glucose results to adjust medication, exercise or meals. Fifty-one percent of the patients reported a greater trust in their measurements after the second visit. Eighty percent of patients wished to have their measurements assessed yearly. Of these patients, 83% preferred to have the assessment done at the community pharmacy. Conclusion: A community pharmacy-based quality assessment procedure of patients’ self monitoring of blood glucose significantly reduced the number of user errors. The analytical quality of the

    Utilizing Near-infrared Spectroscopy for non-invasive glucose concentration sensing has been a focusing topic in biomedical optics applications. In this paper study on measuring conditions of spectroscopy on human body is carried out and a series of experiments on glucose concentration sensing are conducted. First, Monte Carlo method is applied to simulate and calculate photons" penetration depth within skin tissues at 1600 nm. The simulation results indicate that applying our designed optical probe, the detected photons can penetrate epidermis of the palm and meet the glucose sensing requirements within the dermis. Second, we analyze the influence of the measured position variations and the contact pressure between the optical fiber probe and the measured position on the measured spectrum during spectroscopic measurement of a human body. And, a measurement conditions reproduction system is introduced to enhance the measurement repeatability. Furthermore, through a series of transmittance experiments on glucose aqueous solutions sensing from simple to complex we found that though some absorption variation information of glucose can be obtained from measurements using NIR spectroscopy, while under the same measuring conditions and with the same modeling method, choices toward measured components reduce when complication degree of components increases, and this causes a decreased prediction accuracy. Finally, OGTT experiments were performed, and a PLS (Partial Least Square) mathematical model for a single experiment was built. We can easily get a prediction expressed as RMSEP (Root Mean Square Error of Prediction) with a value of 0.5-0.8mmol/dl. But the model"s extended application and reliability need more investigation.

    The energy supplied to the brain by metabolic substrate is largely utilized for maintaining synaptic transmission. In this regulation cerebral blood flow and glucose consumption is tightly coupled as well in the resting condition as during activation. Quantification of cerebral blood flow...... and metabolism was originally performed using the Kety-Schmidt method and this method still represent the gold standard by which subsequent methods have been evaluated. However, in its classical setting, the method overestimates cerebral blood flow. Studies of metabolic changes during activation must take...... difficulties due to limitation in resolution and partial volume effects. In contrast to the tight coupling between regional glucose metabolism and cerebral blood flow, there is an uncoupling between flow and oxygen consumption as the latter only increases to a limited extend. The excess glucose uptake is thus...

  7. Gcg-XTEN: an improved glucagon capable of preventing hypoglycemia without increasing baseline blood glucose.

    Directory of Open Access Journals (Sweden)

    Nathan C Geething

    Full Text Available OBJECTIVE: While the majority of current diabetes treatments focus on reducing blood glucose levels, hypoglycemia represents a significant risk associated with insulin treatment. Glucagon plays a major regulatory role in controlling hypoglycemia in vivo, but its short half-life and hyperglycemic effects prevent its therapeutic use for non-acute applications. The goal of this study was to identify a modified form of glucagon suitable for prophylactic treatment of hypoglycemia without increasing baseline blood glucose levels. METHODOLOGY/PRINCIPAL FINDINGS: Through application of the XTEN technology, we report the construction of a glucagon fusion protein with an extended exposure profile (Gcg-XTEN. The in vivo half-life of the construct was tuned to support nightly dosing through design and testing in cynomolgus monkeys. Efficacy of the construct was assessed in beagle dogs using an insulin challenge to induce hypoglycemia. Dose ranging of Gcg-XTEN in fasted beagle dogs demonstrated that the compound was biologically active with a pharmacodynamic profile consistent with the designed half-life. Prophylactic administration of 0.6 nmol/kg Gcg-XTEN to dogs conferred resistance to a hypoglycemic challenge at 6 hours post-dose without affecting baseline blood glucose levels. Consistent with the designed pharmacokinetic profile, hypoglycemia resistance was not observed at 12 hours post-dose. Importantly, the solubility and stability of the glucagon peptide were also significantly improved by fusion to XTEN. CONCLUSIONS/SIGNIFICANCE: The data show that Gcg-XTEN is effective in preventing hypoglycemia without the associated hyperglycemia expected for unmodified glucagon. While the plasma clearance of this Gcg-XTEN has been optimized for overnight dosing, specifically for the treatment of nocturnal hypoglycemia, constructs with significantly longer exposure profiles are feasible. Such constructs may have multiple applications such as allowing for more

    We studied the expression of genes, which responsible for glucose metabolism, in the blood of obese boys with and without of insulin resistance as well as in normal (control) individuals. It was shown that the expression level of PFKFB3 gene is increased, PFKFB1 and INSIG2--is decreased, but HK2 gene--significantly does not change in the blood cells of obese boys with normal insulin sensitivity as compared to control group. Insulin resistance in obese boys leads to up-regulation of INSIG2 gene expression as well as to down-regulation of PFKFB1, PFKFB3, and HK2 genes in the blood.cells as compared to obese patients with normal insulin sensitivity. Results of this study provide evidence that obesity affects the expression of the subset of glucose metabolism-related genes in the blood cells and that insulin resistance in obesity is associated with changes in the expression level of PFKFB1, PFKFB3, HK2, and INSIG2 genes, which contribute to the development of insulin resistance as well as glucose intolerance.

    Background Extra glucose load in peritoneal dialysis is an important cause of newly-occurred diabetic mellitus, which initiates insulin treatment in some of the dialytic patients.The purpose of this study was to discuss the influence of the peritoneal transfer status on fasting blood glucose in non-diabetic nephropathy patients who are on continuous ambulatory peritoneal dialysis (CAPD).Methods One hundred and forty-five patients with total KT/V per week over 2.0 were recruited, including 60 males and 85 females. Fasting blood glucose (FBG), creatinine, blood urea nitrogen (BUN), blood albumin, blood lipid profile and blood C-reactive protein (CRP) were analyzed at the beginning of the peritoneal dialysis and after 12 months. A peritoneal equilibration test (PET) was carried out at the 3rd month of CAPD, and meantime residual renal function, peritoneal solute clearance rate, ultrafiltration volume and urine volume were also evaluated.Results Twenty-one cases were identified as a low transfer group (L), 32 cases as a low average transfer group (LA), 58 cases as a high average transfer group (HA) and 34 cases as a high transfer group (H). At the end of the 12th month, 83 cases had elevated FBG Through stepwise multiple regression analysis we found the FBG level in these patients was positively related to glucose load and CRP, and negatively related to glucose absorption in the peritoneum (D/D_0) and blood albumin (P<0.05). Kaplan-Meier analysis during a 48-month follow-up found the morbidity of hyperglycemia to be 17/34 cases (50.1%) in the high transfer group, 20/58 cases (34.5%) in the high average transfer group, 11/32 cases (34.3%) in the low average transfer group, and 1/21 cases (5.4%) in the low transfer group.Conclusions Patients with high peritoneal transfer capacity might have the highest morbidity from hyperglycemia among patients with these four different peritoneal transfer status. Glucose load, baseline CRP and FBG level before peritoneal dialysis, and

    2009-01-01

    The main pathophysiological feature of sepsis is the uncontrollable activation of both pro- and anti-inflammatory responses arising from the overwhelming production of mediators such as pro- and anti-inflammatory cytokines. Such an uncontrollable inflammatory response would cause many kinds of metabolic derangements.One such metabolic derangement is hyperglycemia.Accordingly, control of hyperglycemia in sepsis is considered to be a very effective therapeutic approach. However, despite the initial enthusiasm, recent studies reported that tight glycemic control with intensive insulin therapy failed to show a beneficial effect on mortality of patients with severe sepsis and septic shock. One of the main reasons for this disappointing result is the incidence of harmful hypoglycemia during intensive insulin therapy. Therefore, avoidance of hypoglycemia during intensive insulin therapy may be a key issue in effective tight glycemic control.It is generally accepted that glycemic control aimed at a blood glucose level of 80-100 mg/dL, as initially proposed by van den Berghe, seems to be too tight and that such a level of tight glycemic control puts septic patients at increased risk of hypoglycemia. Therefore,now many researchers suggest less strict glycemic control with a target blood glucose level of 140-180 mg/dL.Also specific targeting of glycemic control in diabetic patients should be considered. Since there is a significant correlation between success rate of glycemic control and the degree of hypercytokinemia in septic patients,some countermeasures to hypercytokinemia may be an important aspect of successful glycemic control. Thus,in future, use of an artificial pancreas to avoid hypoglycemia during insulin therapy, special consideration of septic diabetic patients, and control of hypercytokinemia should be considered for more effective glycemic control in patients with severe sepsis and septic shock.

    For different individuals with diabetes,blood glucose control varies. In the blood glucose controlling,blood glucose levels are sometimes higher than the target, sometimes the diabetic patients may develop hypoglycemia. In insulin therapy for blood glucose fluctuations, the most important thing is to avoid hypoglycemia. Finding out regular patterns of blood glucose fluctuations,then according to that,we need to choose the right insulin preparations to treat the condition. For the patients with irregular fluctuations of blood glucose,insulin pump therapy should be a proper choice.%血糖控制因人而异.在血糖控制中,血糖水平有时会明显高于靶目标,有时会发生低血糖.胰岛素干预血糖波动最重要的是不发生低血糖.摸清血糖波动的规律,依据血糖波动情况选择合理的胰岛素制剂.对于无规律的血糖波动等情况宜选择胰岛素泵(CSII)治疗.

    In an animal experiment with the electrocatalytic glucose sensor, measurements were carried out over one week in the extracorporeal circulation of a sheep. Glucose tolerance tests were performed, and the influence of increased urea concentrations in the blood on the glucose determination was investigated. The sensor constructed as a flow-through cell was integrated via a vascular graft outside the body into the carotid artery of the animal and activated by an external electronic unit of measurement. The glucose concentration was determined by measuring the impedance of the electrode/membrane system at various potentials. By means of a subsequent correlation analysis of the measured values obtained over one week, a calibration valid for the entire measurement period was established. After a zero adjustment, it was even possible to adopt the calibration from the glucose measurement of the preceding animal experiment. The investigations of the influence of urea on the glucose measurement showed that the error in measurement of the sensor, which is 20% on average, is only insignificantly increased when the urea level is raised beyond the maximum physiological concentration.

    Full Text Available Abstract Background An elevated plasma glucose concentration has been considered to be a potential risk factor in the pathogenesis of left-displaced abomasums (DA. Therefore the present study was performed to investigate if spontaneous disease (parturient paresis, metritis, ketosis etc in dairy cows results in elevated concentrations of glucose and cortisol in blood as cortisol is the major regulator of glucose in ruminants. Methods Cortisol, insulin, β-hydroxybutyric acid (BHBA, non esterified fatty acids (NEFA, and serum calcium were analyzed in blood serum and glucose, in whole blood, from 57 spontaneously diseased cows collected at different farms. The cows were grouped according to the disease; parturient paresis, recumbent for other reasons, mastitis, metritis, ketosis, inappetance and others. Results No elevated concentrations of cortisol or glucose were found in cows with metritis and mastitis but both cortisol and glucose were elevated in cows stressed by recumbency. Cows with ketonemia (BHBA > 1.5 mmol/l did not have low concentration of glucose in blood but significantly low levels of cortisol. Some of these cows even had cortisol concentrations below the detection limit of the analysing method ( Conclusions The study gives patho-physiological support to the treatment strategies of ketosis, recommending glucocorticoids, insulin etc. However further studies of this problem are needed to understand why cows with ketosis have low levels of cortisol and normal levels of glucose. To what extent elevated cortisol and glucose levels in hypocalcemic and recumbent cows are involved in the ethiology and /or the pathogenesis of DA also will need further research.

  17. Effects of previous protein intake on rectal temperature, blood glucose, plasma thyroid hormone and minerals by laying hens during a forced molt

    International Nuclear Information System (INIS)

    The effects of forced molting on blood glucose, rectal temperature, plasma T4, T3 and minerals were studied in hens previously fed rations with different protein contents (14, 17 and 20% crude protein). Blood samples were obtained from brachial veins for blood glucose, T4 and T3 were measured by radioimmunoassay, and plasma minerals were determined by atomic absorption spectroscopy. Blood glucose and rectal temperature were reduced during fasting regardless of previous protein intake. Pre molting T4 plasma level was higher in laying hens fed higher protein ration, but feed deprivation reduced T4 and T3 concentrations irrespective of protein intake, except T4 level for 14% crude protein fed birds that increased during fasting. The data obtained in this experiment suggest that previous protein intake does not interfere with the metabolic changes during forced molt. (author). 19 refs, 1 fig, 4 tabs

    Creatine kinase (CK: adenosine-5-triphosphate-creatine phosphotransferase) is an important enzyme of muscle cells; the presence of a large amount of the enzyme in blood serum is a biomarker of muscular injuries, such as acute myocardial infarction. This work describes a bi-enzyme (glucose oxidase and hexokinase based) biosensor for rapid and convenient determination of CK activity by measuring the rate of ATP production by this enzyme. Simultaneously the biosensor determines glucose concentration in the sample. Platinum disk electrodes were used as amperometric transducers. Glucose oxidase and hexokinase were co-immobilized via cross-linking with BSA by glutaraldehyde and served as a biorecognition element of the biosensor. The biosensor work at different concentrations of CK substrates (ADP and creatine phosphate) was investigated; optimal concentration of ADP was 1mM, and creatine phosphate - 10 mM. The reproducibility of the biosensor responses to glucose, ATP and CK during a day was tested (relative standard deviation of 15 responses to glucose was 2%, to ATP - 6%, to CK - 7-18% depending on concentration of the CK). Total time of CK analysis was 10 min. The measurements of creatine kinase in blood serum samples were carried out (at 20-fold sample dilution). Twentyfold dilution of serum samples was chosen as optimal for CK determination. The biosensor could distinguish healthy and ill people and evaluate the level of CK increase. Thus, the biosensor can be used as a test-system for CK analysis in blood serum or serve as a component of multibiosensors for determination of important blood substances. Determination of activity of other kinases by the developed biosensor is also possible for research purposes. PMID:26452867

    Cerebral blood flow, cerebral oxygen metabolic rate and cerebral glucose metabolic rate were measured with positron emission tomography (PET) in four patients with progressive supranuclear palsy (PSP). Decreased blood flow and hypometabolism of oxygen and glucose were found in both subcortical and cortical regions, particularly in the striatum including the head of the caudate nucleus and the frontal cortex. The coupling between blood flow and metabolism was preserved even in the regions which showed decreased blood flow and hypometabolism. These findings indicated the hypofunction, as revealed by decreased blood flow and hypometablolism on PET, both in the striatum and the frontal cortex, and which may underlie the pathophysiological mechanism of motor and mental disturbance in PSP.

Methods Patients with definitely diagnosis of diabetes mellitus were enrolled and the levels of fasting saliva glucose and fasting blood glucose were detected on Hitachi7150, using self-made 2,4,6-tribromo-3-hydroxybenzoic acid(TBHBA) as chromogenic substrate. The correlation coefficient between saliva and blood glucose were calculated for every subjects. Results The individual correlation coefficients between saliva glucose and blood glucose varies greatly between different patients. The average fasting correlation coefficient was 0. 85,the average postprandial correlation coefficient was 0. 79 and the coefficient of variability of fasting correlation coefficient was less than 5% within three months. Conclusion The individual fasting correlation coefficient between saliva glucose and blood glucose could be relatively high and stable. Fasting blood glucose could be replaced by fasting saliva glucose for the noninvasive and fast detection.

    A disposable glucose test strip with an integrated sensing/diffusion-limiting layer was developed. A formulation containing filler, glucose oxidase and electronic mediator was screen-printed over two carbon electrodes to form an integrated sensing/diffusion-limiting layer. On rehydration, the integrated layer does not break up, but swells to form a gelled and three-dimensional meshy reaction zone on the surface of the underlying conductive elements in which reactants and mediator move freely, but interfering species such as red blood cells containing oxygenated hemoglobin are excluded. On the same time, the integrated layer maintains a rate of permeation of the analyte through it with a variation of less than 10% at temperatures ranging from 15 deg. C to 42 deg. C. This biosensor is substantially insensitive to interferents and essentially independent to relevant temperature, which provides a more reliable reading of actual blood glucose value in human whole blood.

    Full Text Available In this paper, a microwave sensor based on an artificial transmission line is proposed for non-invasive blood glucose monitoring. A corresponding numerical model of the sensor implemented in microstrip technology is created in the commercial full-wave numerical simulation tool COMSOL Multiphysics and virtually tested by means of numerical simulations. Blood-glucose solution models with various blood glucose concentrations are used as a model of a biological tissue under test. Furthermore, a possible methodology for performing non-invasive tests is proposed. Sensitivity of the sensor developed here is compared to a sensor based on a section of a conventional microstrip transmission line of the same length and width.

  7. Specificity of noninvasive blood glucose sensing using optical coherence tomography technique: a pilot study

    International Nuclear Information System (INIS)

    Noninvasive monitoring of blood glucose concentration in diabetic patients would significantly reduce complications and mortality associated with this disease. In this paper, we experimentally and theoretically studied specificity of noninvasive blood glucose monitoring with the optical coherence tomography (OCT) technique. OCT images and signals were obtained from skin of Yucatan micropigs and New Zealand rabbits. Obtained results demonstrate that: (1) several body osmolytes may change the refractive index mismatch between the interstitial fluid (ISF) and scattering centres in tissue, however the effect of the glucose is approximately one to two orders of magnitude higher; (2) an increase of the ISF glucose concentration in the physiological range (3-30 mM) may decrease the scattering coefficient by 0.22% mM-1 due to cell volume change; (3) stability of the OCT signal slope is dependent on tissue heterogeneity and motion artefacts; and (4) moderate skin temperature fluctuations (±1 deg. C) do not decrease accuracy and specificity of the OCT-based glucose sensor, however substantial skin heating or cooling (several deg. C) significantly change the OCT signal slope. These results suggest that the OCT technique may provide blood glucose concentration monitoring with sufficient specificity under normal physiological conditions

    Full Text Available Strategies to prevent diabetic microvascular angiopathy focus on the vascular endothelium. Because red blood cells (RBCs are less deformable in diabetes, we explored an original concept linking decreased RBC deformability to RBC ascorbate and hyperglycemia. We characterized ascorbate concentrations from human and mouse RBCs and plasma, and showed an inverse relationship between RBC ascorbate concentrations and deformability, measured by osmotic fragility. RBCs from ascorbate deficient mice were osmotically sensitive, appeared as spherocytes, and had decreased β-spectrin. These aberrancies reversed with ascorbate repletion in vivo. Under physiologic conditions, only ascorbate's oxidation product dehydroascorbic acid (DHA, a substrate for facilitated glucose transporters, was transported into mouse and human RBCs, with immediate intracellular reduction to ascorbate. In vitro, glucose inhibited entry of physiologic concentrations of dehydroascorbic acid into mouse and human RBCs. In vivo, plasma glucose concentrations in normal and diabetic mice and humans were inversely related to respective RBC ascorbate concentrations, as was osmotic fragility. Human RBC β-spectrin declined as diabetes worsened. Taken together, hyperglycemia in diabetes produced lower RBC ascorbate with increased RBC rigidity, a candidate to drive microvascular angiopathy. Because glucose transporter expression, DHA transport, and its inhibition by glucose differed for mouse versus human RBCs, human experimentation is indicated.

    Background: It is reasonable to think that some biochemical characteristics of follicular fluid (FF) surrounding the oocyte may play a critical role in determining the quality of oocyte and the subsequent potential needed to achieve fertilization and embryo development. Objective: This study was carried out to evaluate the levels of FF homocysteine (Hcy) in IVF candidate polycystic ovary syndrome (PCOS) women and any relationships with FF glucose and estradiol (E2) levels. Materials and Methods: In this case control study which was performed in Dr. Tizro Day Care and IVF Center 70 infertile patients were enrolled in two groups: comprising 35 PCOS and 35 non PCOS women. Long protocol was performed for all patients. FF Hcy, glucose and E2 levels were analyzed at the time of oocyte retrieval. Results: It was observed that FF Hcy level was significantly higher in PCOS patients compared with non PCOSs (p<0.01). Observations demonstrated that in PCOS group, the Hcy level increased independent to E2, glucose levels, BMI and age, while the PCOS group showed significantly higher BMI compared with non-PCOS group (p=0.03). However, no significant differences were revealed between groups for FF glucose and E2 levels. Conclusion: Present data showed that although FF glucose and E2 levels were constant in PCOS and non PCOS patients, but the FF Hcy levels in PCOS were significantly increased (p=0.01). PMID:27679823

    For self-monitoring of blood glucose by people with diabetes, the reliability of the measured blood glucose values is a prerequisite in order to ensure correct therapeutic decisions. Requirements for system accuracy are defined by the International Organization for Standardization (ISO) in the standard EN ISO 15197:2003. However, even a system with high analytical quality is not a guarantee for accurate and reliable measurement results. Under routine life conditions, blood glucose measurement results are affected by several factors. First, the act of performing measurements as well as the handling of the system may entail numerous possible error sources, such as traces of glucose-containing products on the fingertips, the use of deteriorated test strips, or the incorrect storage of test strips. Second, ambient and sampling conditions such as high altitude, partial pressure of oxygen, ambient temperature, and the use of alternate test sites can have an influence on measurement results. Therefore, the user-friendliness of a system and the quality of the manufacturer's labeling to reduce the risk of handling errors are also important aspects in ensuring reliable and accurate measurement results. In addition, the analytical performance of systems should be less prone to user errors and ambient conditions. Finally, people with diabetes must be aware of the information and instructions in the manufacturer's labeling and must be able to measure and interpret blood glucose results correctly.

    Both diabetes and periodontal disease are prevalent in China. Poor oral hygiene practice is the major cause of periodontal disease. An association between oral hygiene practice and blood glucose level was reported in individuals with diabetes, but not in the general population. We examined the association in a population-based random survey recruiting 2,105 adults without previously diagnosed diabetes in Chongqing city, China. Plasma glucose and hemoglobin A1c (HbA1c) were measured, and a 2-hour oral glucose tolerance test was conducted for each respondent. Self-reported toothbrushing frequency was used as a proxy for oral hygiene practice. In a linear model controlling for potential confounders (demographic characteristics, socio-economic status, lifestyle risk factors, BMI, dental visit frequency, etc.), urban residents who barely brushed their teeth had an increase of 0.50 (95% CI: 0.10-0.90) mmol/L in fasting plasma glucose, and an increase of 0.26% (0.04-0.47%) in HbA1c, relative to those brushing ≥twice daily; for rural residents, the effects were 0.26 (0.05-0.48) mmol/L in fasting plasma glucose and 0.20% (0.09-0.31%) in HbA1c. Individuals with better oral practice tended to have lower level of blood glucose and HbA1c. Establishing good oral health behavioral habits may be conducive to diabetes prevention and control in the general population. PMID:27385509

    Objective To evaluate the effect of low-dose insulin [1 U/(kg · d)] in combination with selenium [180 g/(kg · d)] on general physiological parameters and glucose transporter (GLUT4) level in skeletal mnscle of streptozotocin (STZ)-induced diabetic rats. Methods Diabetic rats were treated with insulin, selenium, and insulin and selenium in combination for four weeks. The level of blood glucose was determined using One Tonch SnreStep Blood Glucose meter and the level of GLUT4 in skeletal muscle was examined by immunobiotting and immnnohistochemistry. Results Our data showed that insulin in combination with selenium could significantly lower blood glucose level and restore the disturbance in GLUT4 level in skeletal muscle. Treatment with insulin was only partially effective in restoring diabetic alterations. Conclusion It can be concluded that there is a synergistic action between insulin and selenium, and that treatment of diabetic rats with combined doses of insulin and selenium is effective in the normalization of blood glucose level and correction of altered GLUT4 distribution in skeletal mnscle of diabetic rats.

    On March 16 and 17, 2010, the Food and Drug Administration (FDA) presented a public meeting about blood glucose monitoring at the Gaithersberg Hilton Hotel. The meeting was intended to present expert opinions and solicit input from the public about whether to develop new regulatory policies for blood glucose monitors. The meeting was divided into three sections: (1) Clinical Accuracy Requirements for Blood Glucose Monitors, (2) Interferences and Limitations of Blood Glucose Monitors, and (3) Tight Glycemic Control. Many officials from the Center for Devices and Radiologic Health and the Office of In Vitro Diagnostic Devices, which are the parts of FDA that regulate approval of blood glucose monitors, either spoke on the agenda or attended in the audience. Approximately 300 people attended; they were mostly clinicians (such as adult endocrinologists, pediatric endocrinologists, internists, clinical chemists, intensivists, surgeons, nurses, and diabetes educators) or industry officials from companies involved in glucose monitoring, pharmaceutical products, data analysis, or regulatory consulting.

    Background and Aims: The association between hyperglycemia and mortality is believed to be influenced by the presence of diabetes mellitus (DM). In this study, we evaluated the effect of preexisting hyperglycemia on the association between acute blood glucose management and mortality in critically ill patients. The primary objective of the study was the relationship between HbA1c and mortality in critically ill patients. Secondary objectives of the study were relationship between Intensive Care Unit (ICU) admission blood glucose and glucose control during ICU stay with mortality in critically ill patients. Materials and Methods: Five hundred patients admitted to two ICUs were enrolled. Blood sugar and hemoglobin A1c (HbA1c) concentrations on ICU admission were measured. Age, sex, history of DM, comorbidities, Acute Physiology and Chronic Health Evaluation II score, sequential organ failure assessment score, hypoglycemic episodes, drug history, mortality, and development of acute kidney injury and liver failure were noted for all patients. Results: Without considering the history of diabetes, nonsurvivors had significantly higher HbA1c values compared to survivors (7.25 ± 1.87 vs. 6.05 ± 1.22, respectively, P < 0.001). Blood glucose levels in ICU admission showed a significant correlation with risk of death (P < 0.006, confidence interval [CI]: 1.004–1.02, relative risk [RR]: 1.01). Logistic regression analysis revealed that HbA1c increased the risk of death; with each increase in HbA1c level, the risk of death doubled. However, this relationship was not statistically significant (P: 0.161, CI: 0.933–1.58, RR: 1.2). Conclusions: Acute hyperglycemia significantly affects mortality in the critically ill patients; this relation is also influenced by chronic hyperglycemia. PMID:27076705

    The accumulation of lactate in the blood after a high-intensity exercise is associated with an increase of lactate extractions by the brain. Previously, a negative influence of blood lactate on attentional processes has been observed. The present study was carried out to examine the association of high blood lactate levels, induced with a maximal cycling, with another cognitive domain: working memory. For evaluation of working memory two different protocols were used: the first (Self-Ordered Pointing Task) capable of analyzing non-spatial working memory requiring the ability to generate and monitor a sequence of responses and the second for evaluating motor working memory necessary to perform a motor task. The study was carried out in 30 students (15 males and 15 females) who performed exhaustive exercise. In each subject, blood lactate was measured and motor as well as non-motor forms of working memory were evaluated before the exercise, at its end as well as 15 min after the exhaustion. It was observed that an increase of blood lactate levels is associated with a worsening of both types of working memory. PMID:26169760

    A relatively simple, new test-strip for blood-glucose monitoring, the Glucoprofil strip with a reaction-zone of film-foil, was evaluated by testing 100 different blood glucose concentrations between 2.1 and 29.7 mmol/l. The results were obtained visually before and after training to read the color changes of the strip according to the scale on the strip-container. Plasma glucose measurements with the Beckman Glucose-Analyzer were used for reference. The results show that the Glucoprofil-strip readings correlated well with the reference method (r = 0.97), thorough training provided. The mean deviation of the strip results was less than 1 mmol/l. Similar results were obtained using another blood glucose strip, the Haemoglukotest 20-800 R. Our study indicates that the performance of the Glucoprofil strip is satisfactory, and hence the strip may be useful for clinical purposes. Consistent with previous reports we could demonstrate that training improved the reading results of the Glucoprofil strip.

    The number of patients with diabetes has reached over 350 million, and still continues to increase. The need for regular blood glucose monitoring sparks the interest in the development of modern detection technologies. One of those methods, which allows for noninvasive measurements, is Raman spectroscopy. The ability of infrared light to penetrate deep into tissues allows for obtaining measurements through the skin without its perforation. This paper presents the limitations and possibilities of non-invasive blood glucose monitoring with Raman spectroscopy. Especially focusing on the possibilities for device miniaturization. Such device incorporates a Raman spectrometer, a fiber-optical probe, and a computing device (microcontroller, smartphone, etc.) which calculates the glucose concentration using specialized algorithms. Simplification of device design, as well as turbidity correction technique and a new proposed method of synchronized detection are described.

    2016-01-01

    Much research in social psychology has investigated the impact of bodily energy need on cognition and decision-making. As such, blood glucose, the body's primary energy source, has been of special interest to researchers for years. Fluctuations in blood glucose have been linked to a variety of changes in cognitive and behavioral processes, such as self-control, political attitudes, and eating behavior. To help meet growing interest in the links between bodily energy need and these processes, this manuscript offers a simple methodology to experimentally manipulate blood glucose using a fasting procedure followed by administration of a sugar-sweetened, unsweetened, or artificially-sweetened beverage. This is followed by presentation of a method for measuring resulting changes in implicit cognition using a lexical decision-task. In this task, participants are asked to identify whether strings of letters are words or non-words and response latencies are recorded. Sample results from a recent publication are presented as an example of the applications for the experimental manipulation of blood glucose and the lexical decision task measures. PMID:27585282

    Although hippocampal infusions of glucose enhance memory, we have found repeatedly that septal glucose infusions impair memory when γ-aminobutyric acid (GABA) receptors are activated. For instance, hippocampal glucose infusions reverse the memory-impairing effects of co-infusions of the GABA agonist muscimol, whereas septal glucose infusions exacerbate memory deficits produced by muscimol. One potential explanation for these deleterious effects of glucose in the septum is that there are highe...

    During the past decade, many salivary parameters have been used to characterize disease states. Ghrelin (GAH) is recently-discovered peptide hormone secreted mainly from the stomach but also produced in a number of other tissues including salivary glands. The aim of this work was to examine the relationship between active (aGAH) and inactive (dGAH) ghrelin in the saliva and other salivary parameters in type II diabetic patients and healthy controls. Salivary parameters were assessed in a single measurement of unstimulated whole saliva from 20 obese and 20 non-obese type II diabetes patients, and in 22 healthy controls. Total protein and alpha-amylase were determined by colorimetric methods, and glucose by the glucose-oxidase method. Saliva aGAH and dGAH levels were measured using a commercial radioimmunoassay (RIA) kit. Salivary concentrations of aGAH and dGAH ghrelin were more markedly decreased in obese diabetic subjects than in the two other groups. Glucose and alpha-amylase levels were higher in diabetic subjects than in controls. Furthermore, there were correlations between GAH levels and BMI, and between GAH and blood pressure. However, there was no marked variability in saliva flow rates among the groups. These results indicate that measurement of salivary GAH and its relationship to other salivary parameters might help to provide insight into the role of ghrelin in diabetes. PMID:17244479

    Natal dispersal of sea turtles is an energetically demanding activity that is fuelled primarily by aerobic metabolism. However, during intense exercise reptiles can use anaerobic metabolism to supplement their energy requirements. We assessed anaerobic metabolism in dispersing hatchling loggerhead and flatback turtles by measuring the concentrations of blood lactate during crawling and at different times during the first four hours of their frenzy swim. We also measured concentrations of blood glucose and corticosterone. Blood lactate (12.13 to 2.03 mmol/L, glucose (6.25 to 3.8 mmol/L and corticosterone (8.13 to 2.01 ng/mL concentrations decreased significantly over time in both loggerhead and flatback hatchlings and no significant differences were found between the species. These results indicate that anaerobic metabolism makes a significant contribution to the dispersal phase of hatchling sea turtles during the beach crawl and the first few hours of the frenzy swim.

    Nerve cell metabolism in post brain ischemia depends on increased microcirculation perfusion and transport function of microvascular endothelial cells. In the present study, a rat model of middle cerebral artery occlusion was established to investigate the influence of electroacupuncture(EA)on hippocampal CA1 cerebral blood flow and glucose transporter 1(GLUT1)expression in the microvascular endothelial cp.lls. Following EA at Neiguan(PC 6), the cerebral blood flow in the ischemic hippocampal CA1 region was significantly elevated, the number and microvascular integrated absorbance of the GLUTl-positive cells were significantly increased, nerve cell damage was ameliorated, and GLUT1 protein expression in the ischemic hippocampus was significantly increased. Results demonstrate that EA increased the cerebral blood flow of the hippocampal CA1 region and improved the glucose transport function, thereby attenuating neuronal injuries.

    Background The probability and risk of operations increase in patients with type 2 diabetes mellitus.For diabetic patients,blood glucose control is a key factor to improving the prognosis of surgery.During perioperative period,insulin therapy is usually advised to be used for surgical patients with type 2 diabetes.However,the insulin regimen which one is better remains controversial.In this study,we estimated the efficacy,safety and advantage of different insulin therapy strategy during perioperative period.Methods A total of 1086 cases of surgical patients with type 2 diabetes mellitus enrolled in the present study.According to the glucose level at admission,all patients were divided into relatively high glucose group (group A,fasting blood glucose (FBG) <13.9 mmol/L) and higher glucose group (group B,FBG >13.9 mmol/L).Patients in group A randomly accepted premixed insulin twice a day,or basal insulin plus oral medications,and were divided into group A1 and A2 respectively.Patients in group B randomly received premixed insulin twice daily,basal insulin plus oral hypoglycemic agents,or basal insulin plus preprandial insulin,and were divided into group B1,B2 and B3 respectively.The data of the preoperative preparation time,the daily doses of insulin used in different periods,postoperative incision healed installments,hypoglycemic events,the total hospitalization time,postoperative complications were all collected and statistically analyzed.Results Compared the main outcome measures in groups treated by premixed insulin therapy,both in preoperative preparation and postoperative period,the daily insulin dosage and the frequency of hypoglycemic events were decreased in groups treated by basal insulin therapy (P <0.05).The preoperative preparation time and the total hospitalization time in groups with basal insulin therapy were shorter than that in groups with premixed insulin therapy (P <0.05).The incision healing rate of stage Ⅰ,Ⅱ and Ⅲ among different

    Background The debate over the overall benefits of self-monitoring of blood glucose in type 2 diabetes patients is still continuing.We aimed to assess the difference in glycaemic control and coronary heart disease (CHD) risk levels of experimental type 2 diabetes patients provided with facilities for self-monitoring blood glucose and their counterparts without such facilities.Methods Sixty-one patients who had no prior experience in using glucometers were studied as intervention (n=30) and control (n=31) groups.The intervention group was trained in self-monitoring of blood glucose and documentation.Baseline blood glucose and fasting blood glucose were measured and the intervention patients were provided with glucometers and advised to self-monitor their fasting and postprandial blood glucose over six months.The 10-year CHD risk levels were determined with the United Kingdom Prospective Diabetes Study-derived risk engine calculator.Results The age and diabetes duration were similar in the two groups (P >0.05).The majority of the patients were unemployed or retired females with only a primary level education.After 3 months,the haemogolbin A1c (HbA1c) levels of the control patients remained unchanged ((7.8±0.3)% vs.(7.9±0.4)%,P >0.05) whereas the HbA1c levels of the intervention patients were significantly reduced from the baseline at three ((9.6±0.3)% vs.(7.8±0.3)%,P <0.001) and six ((9.2±0.4)% vs.(7.5±0.3)%,P <0.001) months.Interestingly,while the 10-year CHD risk level of the control group remained unchanged after three months,that of the intervention group was remarkably reduced at three and six months from the baseline level ((7.4±1.3)% vs.(4.5±0.9)%,P=0.056).Conclusion Self-monitoring of blood glucose in type 2 diabetes patients significantly improved glycaemic control and the CHD risk profile,suggesting that type 2 diabetes patients will potentially benefit from inclusion of glucose meters and testing strips in their health-care package.

    A nutritive sweetener, aspartame (L-aspartyl-L-phenylalanine methylester) was administered orally to normal controls and diabetic patients in order to evaluate effects on blood glucose, lipids and pancreatic hormone secretion. An oral glucose tolerance test was also performed in the same subjects as a control study of aspartame administration. In 7 normal controls and 22 untreated diabetics, a single dose of 500 mg aspartame, equivalent to 100 g glucose in sweetness, induced no increase in blood glucose concentration. Rather, a small but significant decrease in blood glucose was noticed 2 or 3 h after administration. The decrease in blood glucose was found to be smallest in the control and became greater as the diabetes increased in severity. No significant change in blood insulin or glucagon concentration during a 3-h period was observed in either the controls or the diabetics. The second study was designed to determine the effects of 2 weeks' continuous administration of 125 mg aspartame, equal in sweetness to the mean daily consumption of sugar (20-30 g) in Japan, to 9 hospitalized diabetics with steady-state glycemic control. The glucose tolerance showed no significant change after 2 weeks' administration. Fasting, 1 h and 2 h postprandial blood glucose, blood cholesterol, triglyceride and HDL-cholesterol were also unaffected. From these and other published results, aspartame would seem to be a useful alternative nutrient sweetener for patients with diabetes mellitus. PMID:3522147

    Glucose meters (GMs) are routinely used for self-monitoring of blood glucose by patients and for point-of-care glucose monitoring by health care providers in outpatient and inpatient settings. Although widely assumed to be accurate, numerous reports of inaccuracies with resulting morbidity and mortality have been noted. Insulin dosing errors based on inaccurate GMs are most critical. On October 28, 2011, the Diabetes Technology Society invited 45 diabetes technology clinicians who were attending the 2011 Diabetes Technology Meeting to participate in a closed-door meeting entitled New Criteria for Assessing the Accuracy of Blood Glucose Monitors. This report reflects the opinions of most of the attendees of that meeting. The Food and Drug Administration (FDA), the public, and several medical societies are currently in dialogue to establish a new standard for GM accuracy. This update to the FDA standard is driven by improved meter accuracy, technological advances (pumps, bolus calculators, continuous glucose monitors, and insulin pens), reports of hospital and outpatient deaths, consumer complaints about inaccuracy, and research studies showing that several approved GMs failed to meet FDA or International Organization for Standardization standards in postapproval testing. These circumstances mandate a set of new GM standards that appropriately match the GMs' analytical accuracy to the clinical accuracy required for their intended use, as well as ensuring their ongoing accuracy following approval. The attendees of the New Criteria for Assessing the Accuracy of Blood Glucose Monitors meeting proposed a graduated standard and other methods to improve GM performance, which are discussed in this meeting report.

    This study examined the extent to which the potentially toxic lead particulates emitted from motor vehicles are absorbed by competitive cyclists. A time trial (n = 5), a road race (n = 5), and a sedentary control group (n = 5) were examined with respect to blood lead (PbB) levels. In the two cycling groups, the PbB levels were measured before and after (1) a time trial (80 km) held on a dual carriageway; and (2) a road race (120 km) which took place in a rural area. Mean (+/- SE) resting PbB levels for the sedentary subjects, time trialists, and road racers were 0.442 +/- 0.041, 0.490 +/- 0.111 and 0.384 +/- 0.061 mumol l-1 respectively (p > 0.05). Mean post-race PbB levels of the time trialists (0.528 +/- 0.046 mumol l-1) and road racers (0.346 +/- 0.024 mumol l-1) did not differ significantly from the pre-race levels (p > 0.05). However, after their respective races, the mean PbB level of the time trialists was higher than that of the road racers (p cycling (70% VO2 max) in a laboratory containing approximately 1 microgram m3 of airborne lead did not affect blood lead levels. All PbB levels compiled with EC regulations regarding lead exposure. Despite a positive relationship between the amount of training and the PbB levels (r = 0.64, p road racing.(ABSTRACT TRUNCATED AT 250 WORDS)

Rats in the diabetic nephropathy and stem cel transplantation groups were given single use of 60 mg/kg streptozotocin to make diabetic nephropathy models. The same dose of citric acid-sodium citrate buffer was injected in the normal control group. After modeling, 200μL of bone marrow mesenchymal stem cel solution (2×106) was injected into the left ventricle of rats in the stem cel transplantation group, and then at 7 days after the first transplantation, the cel transplantation was conducted again. The same dose of serum-free L-DMEM was injected intracardialy into the rats in the normal control and diabetic nephropathy groups. Levels of urinary total protein and blood glucose were detected. RESULTS AND CONCLUSION:At 1, 4, 8 weeks after treatment, the urinary total protein and blood glucose levels were significantly higher in the stem cel transplantation group and diabetic nephropathy group than the normal control group (P 0.05). These findings indicate that bone marrow mesenchymal stem cel transplantation in diabetic nephropathy rats can get good results in a short period, significantly improve the blood glucose and urinary total protein levels, but the long-term treatment effect is poor.%背景:糖尿病肾病防治的基本措施包括有效控制血糖、控制血压、抑制肾素-血管紧张素系统和调脂治疗等,但往往无法获得理想的效果

    Graphical abstract: -- Highlights: •Hemin is assembled onto the surfaces of graphene quantum dots (GQDs). •With the aid of hemin, H{sub 2}O{sub 2} could quench the FL signal of GQDs obviously. •Based on this effect, a fluorescent platform is proposed for the sensing of glucose. •The proposed method provides a new pathway to explore practical application of GQDs. -- Abstract: In the present work, a highly sensitive and specific fluorescent biosensor for blood glucose monitoring is developed based on hemin-functionalized graphene quantum dots (GQDs) and glucose oxidase (GOx) system. The GQDs which are simply prepared by pyrolyzing citric acid exhibit strong fluorescence and good water-solubility. Due to the noncovalent assembly between hemin and GQDs, the addition of hemin can make hydrogen peroxide (H{sub 2}O{sub 2}) to destroy the passivated surface of GQDs, leading to significant fluorescence quenching of GQDs. Based on this effect, a novel fluorescent platform is proposed for the sensing of glucose. Under the optimized conditions, the linear range of glucose is from 9 to 300 μM, and the limit of detection is 0.1 μM. As unique properties of GQDs, the proposed biosensor is green, simple, cost-efficient, and it is successfully applied to the determination of glucose in human serum. In addition, the proposed method provides a new pathway to further design the biosensors based on the assembly of GQDs with hemin for detection of biomolecules.

    This study assessed the response to a glucose tolerance test in dairy goats with pregnancy toxemia (PT), in healthy, pregnant, non-lactating dairy goats in the last month of gestation (HP), and in healthy, lactating, non-pregnant, dairy goats in mid-lactation (HL). A 500 mL volume of a 5% glucose solution was administered by the IV route. Blood glucose concentrations returned to pre-infusion levels by 90 min in all 8 HL goats, and by 180 min in all 8 HP goats. In contrast, concentrations of blood glucose were still significantly above pre-infusion levels at 180 min post-infusion in all 8 PT goats. Thus, marked glucose intolerance was demonstrated in the PT goats, and mild intolerance was noted in the HP goats. In 25 goats diagnosed with PT and having blood beta hydroxybutyric acid (BHBA) values ≥ 2.9 mmol/L, the correlation coefficient for BHBA with blood pH was non-significant. PMID:27247464

    This study investigated the effects of two common cooking oils (palm oil, PO) and (groundnut oil, GO) supplementation on the antioxidant status and diabetic indices in Alloxan (100mg/kg) induced diabetic Wistar rats. A total of forty-eight Wistar rats of both sexes were used for this study. They were divided into four groups of 12 animals each as: control, diabetic non-supplemented, diabetic supplemented with PO (200mg/kg/day) and diabetic supplemented with GO (200mg/kg/day) rats. Blood glucose, plasma vitamin E, SOD, Total Protein and Albumin levels were measured using standard laboratory procedures. After three weeks of supplementation there was a significant (pglucose of supplemented groups compared with the diabetic non-supplemented group. Plasma Vitamins C and E, SOD, and Albumin levels were significantly (psupplemented groups when compared with the diabetic non-supplemented group. However, the plasma levels of these parameters were found to be significantly (psupplemented rats compared with the PO supplemented group. The plasma vitamin C levels in the diabetic groups were lower than in other groups while increased levels in the plasma total protein were not significant. There was no significant difference in the measured parameters in reference to the gender of the animals. It was concluded from this study that GO exhibited superior antioxidant activities and that the supplementation of red palm oil and ground nut oil as a source of antioxidant was beneficial in diabetic state as it reduced blood glucose and enhance antioxidant status.

    Full Text Available Abstract Background Increased coronary intima media thickness (CIMT has been associated with adverse cardiovascular outcomes, as have increased glucose levels. The link has not been established between glucose and CIMT; therefore, we sought to assess the relationship between glucose and CIMT. Methods Medline, EMBASE, Scopus, and Cochrane databases were searched from inception through 2009 for original research reporting both postprandial glucose levels and CIMT measurements. Glucose was classified as normal, impaired, or diabetic. Outputs included inverse variance weighted effect size and also average correlation (using the Wang and Bushman approach. Data were combined using a random effects meta-analytic model. Heterogeneity as assessed using χ2 and I2; bias was examined using Egger plots and Begg-Mazumdar tau. Polynomial functions (i.e., linear, quadratic, cubic, quartic were fit to the data and the Akaike Information Criteria were used to select the optimal model. Results We identified 172 papers; 161 were rejected (19 inappropriate design, 8 had selected patients, 101 inappropriate outcomes leaving 11 accepted. We used data from 15,592 patients (8250 normals, 3013 impaired glucose, 4329 diabetics. There was no evidence of heterogeneity or publication bias. The overall correlation was 0.082 (CI95%:0.066-0.098; the overall effect size was 0.294 (0.245-0.343 between diabetics and normals and 0.137 (0.072-0.202 between normals and those with impaired glucose. The equation of best fit was linear (CIMT = 0.828 + 0.009*glucose. Conclusions There is a small but significant relationship between postprandial glucose levels and CIMT, which have both been associated with adverse cardiovascular outcomes.

    Background This study evaluated performance and product labeling of CONTOUR® USB, a new blood glucose monitoring system (BGMS) with integrated diabetes management software and a universal serial bus (USB) port, in the hands of untrained lay users and health care professionals (HCPs). Method Subjects and HCPs tested subject's finger stick capillary blood in parallel using CONTOUR USB meters; deep finger stick blood was tested on a Yellow Springs Instruments (YSI) glucose analyzer for reference. Duplicate results by both subjects and HCPs were obtained to assess system precision. System accuracy was assessed according to International Organization for Standardization (ISO) 15197:2003 guidelines [within ±15 mg/dl of mean YSI results (samples <75 mg/dl) and ±20% (samples ≥75 mg/dl)]. Clinical accuracy was determined by Parkes error grid analysis. Subject labeling comprehension was assessed by HCP ratings of subject proficiency. Key system features and ease-of-use were evaluated by subject questionnaires. Results All subjects who completed the study (N = 74) successfully performed blood glucose measurements, connected the meter to a laptop computer, and used key features of the system. The system was accurate; 98.6% (146/148) of subject results and 96.6% (143/148) of HCP results exceeded ISO 15197:2003 criteria. All subject and HCP results were clinically accurate (97.3%; zone A) or associated with benign errors (2.7%; zone B). The majority of subjects rated features of the BGMS as “very good” or “excellent.” Conclusions CONTOUR USB exceeded ISO 15197:2003 system performance criteria in the hands of untrained lay users. Subjects understood the product labeling, found the system easy to use, and successfully performed blood glucose testing. PMID:22027308

    Emerging data suggest that elevated glucose may promote inflammatory activation of monocytic lineage cells with the ability to injure vascular endothelial tissue of diabetic patients, however evidence in primary human monocytes and macrophages is still insufficient. We investigated the effect of high glucose concentration on the inflammatory capacity of human macrophages in vitro and examined whether similar responses were detectable in circulating monocytes from prediabetic patients. Primary monocytes were isolated from healthy blood donors and differentiated into macrophages. Differentiated macrophages were exposed to normal levels of glucose (NG), high glucose (HG) or high mannitol as osmotic pressure control (OP) for three days. Using PCR, ELISA and flow cytometry, we found that HG macrophages showed overexpression of CD11c and inducible nitric oxide synthase as well as down-regulation of arginase-1 and interleukin (IL)-10 with respect to NG and OP macrophages. Consistent with in vitro results, circulating monocytes from hyperglycemic patients exhibited higher levels of CD11c and lower expression of CD206 than monocytes from normoglycemic controls. In subjects with hyperglycemia, elevation in CD11c(+) monocytes was associated with increased obesity, insulin resistance, and triglyceridemia as well as low serum IL-10. Our data suggest that human monocytes and macrophages undergo M1-like inflammatory polarization when exposed to high levels of glucose on in vitro culture conditions and in patients with hyperglycemia. These results demonstrate that excess glucose has direct effects on macrophage activation though the molecular mechanisms mediating such a response remain to be elucidated. PMID:27269375

    Full Text Available A potential association between diabetes and Guillain-Barré syndrome (GBS has been indicated by a few case studies. We retrospectively analyzed the clinical features of a large cohort of GBS patients to explore the relationship between the level of fasting plasma glucose (FPG obtained in the acute phase at admission and the severity of GBS.Three hundred and four GBS patients were divided into two groups, one with normal FPG and the other with high FPG levels according to the international standards of FPG.The GBS disability scale score was positively, the Medical Research Council (MRC sum score was negatively correlated to the level of FPG, but not to blood HBA1c or CSF glucose concentrations. A relatively higher FPG level was observed in older and younger GBS patients, and more often in those with cranial nerve involvement, autonomic deficit, dyspnea and ventilator dependence than in patients without these clinical characteristics. Importantly, higher levels of FPG at admission were associated with poorer short-term prognosis measured by the MRC sum score and the GBS disability scale at discharge.Our data demonstrates that FPG in the acute phase of GBS correlates with the severity of GBS and may predict the short-term prognosis of GBS.

    Full Text Available Objective: Diabetes mellitus affects every organ in the man including eyes, kidney, heart, and nervous system. Alcohol consumption is a widespread practice. As the effects of chronic alcohol consumption on diabetic state have been little studied, this study was conducted with the objective of evaluating the effect of alcohol in diabetic rats. Materials and Methods: For this study, the rats were divided into five groups (n = 6 in each group: normal control (NC, alcohol treatment (At, diabetic control (DC, diabetic plus alcohol treatment (D + At, diabetic plus glibenclamide treatment (D + Gli. Alcohol treatment was given to the diabetic rats for 30 days. During the period the blood glucose levels, and body weight changes were observed at regular intervals. The antioxidant enzymes like superoxide dismutase (SOD, catalase (CAT, and malondialdehyde (MDA levels were assayed in the liver and kidney tissues. Results: The blood glucose levels were significantly (P < 0.001 elevated and body weight significantly (P < 0.001 decreased in alcohol-treated diabetic rats. SOD and CAT activities were decreased and the MDA level increased significantly (P < 0.001 in alcohol-treated diabetic rats. Histopathological studies showed that alcohol damages the liver and kidney tissues in diabetic rats. Conclusion: These finddings concluded that the consumption of alcohol in diabetic rats worsens the condition. So the consumption of alcohol by diabetic subjects may be potentially harmful.

    Diabetes is a common metabolic disorder that is specified by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The use of nonpharmacological treatments (herbal agents) is a new approach in the management of diabetes. The aim of this study was to investigate the effect of aqueous extract of alfalfa on blood glucose and serum lipids in alloxan-induced diabetic rats. In this study, 32 female rats (210–250 g) were used which were divided randomly into 4 groups including intact control group, diabetic control group, and 2 diabetic groups which received 250 and 500 mg/kg doses of aqueous extract of alfalfa, respectively. In the diabetic groups, alloxan-monohydrate was injected peritoneally to create diabetic condition. The two last groups orally received aqueous extract of alfalfa for 21 days. At the end of experiment, sugar, cholesterol, triglycerides, high-density and low-density lipoprotein, and aspartate aminotransferase (ALT) and alanine aminotransferase (AST) levels were measured in the samples. Consumption of aqueous alfalfa extract significantly reduced glucose, cholesterol, triglycerides, and low-density lipoprotein (LDL) levels in the diabetic rats but enhanced high-density lipoprotein (HDL) levels. ALT and AST liver enzyme levels were also reduced in blood. Histological examination showed that the aqueous alfalfa extract caused reconstruction of damaged liver and enhanced Langerhans islets’ diameter in pancreas. Therefore, all signs of diabetes were improved by oral administration of alfalfa in defined dose. PMID:26525173

    Selenium (Se) has been implicated as a micronutrient that decreases adenosine monophosphate-activated protein kinase (AMPK) signaling and may increase diabetes risk by reducing insulin sensitivity. Soy isoflavones (IF) are estrogen-like compounds that have been shown to attenuate insulin resistance, hyperglycemia, adiposity, and increased AMPK activation. We hypothesized that a high IF (HIF) diet would prevent the poor metabolic profile associated with high Se intake. The purpose of this study was to examine changes in basal glucose metabolism and AMPK signaling in response to an HIF diet and/or supplemental Se in a mouse model. Male FVB mice were divided into groups receiving either a control diet with minimal IF (low IF) or an HIF diet. Each dietary group was further subdivided into groups receiving either water or Se at a dose of 3 mg Se/kg body weight daily, as Se-methylselenocysteine (SMSC). After 5 months, mice receiving SMSC had elevated fasting glucose (P < .05) and a tendency for glucose intolerance (P = .08). The increase in dietary IF did not result in improved fasting blood glucose. Interestingly, after 6 months, HIF-fed mice had decreased basal AMPK activation in liver and skeletal muscle tissue (P < .05). Basal glucose metabolism was changed by SMSC supplementation as evidenced by increased fasting blood glucose and glucose intolerance. High dietary IF levels did not protect against aberrant blood glucose. In FVB mice, decreased basal AMPK activation is not the mechanism through which Se exerts its effect. These results suggest that more research must be done to elucidate the role of Se and IF in glucose metabolism.

    Electrocortical effects of long duration exercise on cognitive function were investigated by analyzing P300 amplitude and latency changes during a 3-h cycling exercise. P300 components were measured in 12 well-trained cyclists and blood glucose, cortisol, insulin, glycerol, and free fatty acids (FFAs) epinephrine and norepinephrine were analyzed. Results indicated that P300 components were affected by exercise with a temporary increase in amplitude between the 1st and the 2nd hour and an increase in latency after 2 h of exercise concomitant with some hormonal changes, including an increase in cortisol and epinephrine and a decrease in blood glucose. These findings suggest a combined effect of arousal and central fatigue on electrocortical indices of cognitive function during acute physical exercise. PMID:15196681

    Full Text Available We describe how scale space methods can be used for quantitative analysis of blood glucose concentrations from type 2 diabetes patients. Blood glucose values were recorded voluntarily by the patients over one full year as part of a self-management process, where the time and frequency of the recordings are decided by the patients. This makes a unique dataset in its extent, though with a large variation in reliability of the recordings. Scale space and frequency space techniques are suited to reveal important features of unevenly sampled data, and useful for identifying medically relevant features for use both by patients as part of their self-management process, and provide useful information for physicians.

    Type 2 diabetes can be a problem for captive chimpanzees. Accurate blood glucose (BG) readings are necessary to monitor and treat this disease. Thus, obtaining voluntary samples from primates through positive reinforcement training (PRT) is critical. The current study assessed the voluntary participation of 123 chimpanzees in BG sampling and investigated factors that may contribute to individual success. All subjects participate in regular PRT sessions as part of a comprehensive behavioral management program. Basic steps involved in obtaining BG values include: voluntarily presenting a finger/toe; allowing digit disinfection; holding for the lancet device; and allowing blood collection onto a glucometer test strip for analysis. We recorded the level of participation (none, partial, or complete) when each chimpanzee was first asked to perform the testing procedure. Nearly 30% of subjects allowed the entire procedure in one session, without any prior specific training for the target behavior. Factors that affected this initial successful BG testing included sex, personality (chimpanzees rated higher on the factor “openness” were more likely to participate with BG testing), and past training performance for “present-for-injection” (chimpanzees that presented for their most recent anesthetic injection were more likely to participate). Neither age, rearing history, time since most recent anesthetic event nor social group size significantly affected initial training success. These results have important implications for captive management and training program success, underlining individual differences in training aptitude and the need for developing individual management plans in order to provide optimal care and treatment for diabetic chimpanzees in captivity.

    The models of hyperlipidemia tilapia induced by high-fat diet were established to explore the effects of fermented mulberry leaves on serum lipid and blood glucose levels of hyperlipidemia tilapia ( Oreochromis niloticus) . A total of 450 male GIFT tilapia with the initial average body weight of 45 g were randomly divided into 5 groups with 3 replicates per group, and 30 fish in each replicate. The fish in normal control group were fed with a basal diet, and the other 4 groups were fed the basal diet ( model control group) and diets contained 7.5% and 15.0% fermented mulberry leaves ( low level fermented mulberry leaves group and high level fer-mented mulberry leaves group, respectively) , and 0.5% ginkgo flavone ( ginkgo flavone group) after the es-tablishment of the hyperlipidemia model, respectively. The experiment lasted for 8 weeks. The results showed as follows: after feeding 5 and 8 weeks, the body weight in model control group was significantly lower than that in normal control group, low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo flavone group (P0.05) . The serum total cholesterol ( TCHO) and low-density lipoprotein cholesterol ( LDL-C) contents and TCHO/high-density lipoprotein cholesterol ( HDL-C) in low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo fla-vone group were significantly lower than those in model control group (P0.05) . Compared with the model control group, the serum HDL-C content in high level fermented mulberry leaves group and ginkgo flavone group was significantly increased (P0.05). High-fat diet could significantly increase the blood glucose level in model control group, low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo flavone group (0 week, P0.05). These results indicate that fermented mulberry leaves can decrease the serum lipid and blood glucose levels, and enhance the antioxidant ability of

    To investigate the effects of semiconductor laser acupoint irradiation on blood glucose, glycosylated hemoglobin and physical fitness in type 2 diabetes mellitus, 44 cases of type 2 diabetic patients were randomly divided into a control group and a treatment group. All patients in both groups were given a drug treatment. The Hegu, Quchi and Zusanli acupoints of patients in the treatment group were then irradiated daily for 15 d with a 10 MW semiconductor laser. Before and after treatment, patients in both groups underwent a variety of tests and measurements: a two-hour postprandial blood glucose test; a glycosylated hemoglobin test and body mass index (BMI), waist-to-hip ratio (WHR) and body fat percentage (BFP) measurements. The data detected after treatment greatly decreased in the treatment group and was significantly different from that in the control group. It is shown that the acupoint irradiation with a semiconductor laser can improve two-hour postprandial blood glucose, glycosylated hemoglobin and some physical fitness measuremen
