    This article describes suggested treatment regimens for non-insulin-dependent diabetes mellitus. Diet is usually the first-line therapy. If this fails, most patients should be given a trial of oral agents, usually sulfonylurea first. Sulfonylurea and metformin can be combined if necessary. If oral agents fail, insulin is indicated. Insulin and an oral agent sometimes are used together.

    To evaluate changes of pancreatic size with aging in control subjects and in non-insulin- dependent diabetic patients. Two groups of non-insulin-dependent diabetic patients were examined; one had been treated with an oral hypoglycemic agent(n=59), and the other with insulin(n=56). The CT findings of 175 patients without clinical evidence of pancreatic disease were included as a normal control. In control subjects, pancreatic size and age correlated. The pancreas was smaller in non-insulin-dependent diabetics than in control subjects and smaller in insulin- treated non-insulin-dependent diabetics than in non-insulin treated patients. The pancreas was smaller in non-insulin-dependent diabetic patients than in control subjects within the same age range

    Patients with Non-insulin-dependent diabetes mellitus (NIDDM) have defects in insulin secretion and insulin action. In the discrete genetic syndrome of NIDDY (non-insulin-dependent diabetes in the young), the situation is less clear and these aspects is the subject of this thesis. This study included Indian pasients with three generation transmission of NIDDM via one parent. The insulin and C-peptide responses to oral and intravenous glucose in patients with NIDDY were studied. The insulin and glucose responses to non-glucose secretogogues glucagon, tolbutamide and arginine, in NIDDY were also investigated. The following aspects with regard to insulin resistance in NIDDY were examined: glucose and free fatty acid response to intravenous insulin administration, insulin binding to circulating erythrocytes and monocytes, 125 I-insulin binding to the solubilized erythrocyte membrane receptor and 125 I-insulin binding to fibroblasts in culture

    To determine the frequency of Human Leukocyte Antigen (HLA) class II susceptibility conferring alleles among type 2 Diabetes mellitus patients, in comparison with healthy controls. Cross-sectional comparative study. Patients with non-insulin dependent Diabetes mellitus meeting World Health Organization criteria were studied. These were compared with age and gender matched healthy control subjects. For each subject (patients as well as controls), DNA was extracted from ethylene diamine tetra-acetate sample and HLA class II DRB1 typing was carried out at allele group level (DRB1*01-DRB1*16) by sequence specific primers. Human leukocyte antigen DRB1 type was determined by agarose gel electrophoresis and results were recorded. Frequencies were determined as number of an allele divided by total number of alleles per group; p-value was computed using Pearson's chi-square test. Among the 100 patients, there were 63 males and 37 females with 68 controls. A total of 13 different HLA DRB1 alleles were detected, with DRB1*15 being the commonest in both the groups. The allele DRB1*13 had statistically significant higher frequency in patient group as compared to controls (p 0.005). HLA DRB1*13 was found with a significantly increased frequency in non-insulin dependent Diabetes mellitus. (author)

    Full Text Available 77irty six patients with non insulin dependent diabetes mellitus, whose blood sugar was not controlled with maximal doses of oral hypoglycemic agents and did not accept insulin treatment, were selected for this study. The patients were randomly divided into two groups, the treatment group and the control group. The treatment group received oral hypoglycemic agent and chloroquine (150 mg twice daily and the control group received oral hypoglycemic agent and placebo for a period of six months. the fasting blood sugar (FBS and Hb A1C were recorded before and after treatment. The age, sex, weight and duration of disease were similar in both groups (P>0.05. The blood sugar level, was significantly lower after 3-6 months of chloroquine therapy (P < 0.001. Serious drug reactions were not noticed, except for gastrointestinal upset in three patients and hypoglycemia in another two cases. In conclusion we believe that the combination of chloroquine and oral hypoglycemic agents can be useful for the control of blood sugar levels in some resistant cases of non insulin dependent diabetes mellitus.

    To assess the metabolic disturbances, and, in particular, the occurrence of high blood ketone body concentration in post-absorptive Type 2 (non-insulin-dependent) diabetic patients as compared to a matched normal population, a study was carried out in a group of 78 Type 2 diabetic outpatients matched for age and sex and in 78 normal individuals. In all subjects we measured HbA1c, and fasting levels of glucose, FFA, lactate, pyruvate, glycerol, alanine, 3-hydroxybutyrate, acetoacetate, uric acid, total cholesterol, triglycerides, creatinine, growth hormone, cortisol, glucagon, free insulin, and C-peptide. Multistix strips were used for urine ketone determination. As expected HbA1c, and plasma glucose were higher in Type 2 diabetics. This was associated with multiple metabolic disturbances as shown by higher circulating concentrations of FFA, glycerol and gluconeogenic precursors. Similarly, blood levels of ketones (351 +/- 29 vs 159 +/- 15 umol/l; P l; p l; P ketone body levels were directly correlated with both plasma glucose and FFA concentrations. These observations clearly show that Type 2 diabetes is a pathologic condition characterised by multiple metabolic disturbances which are fully apparent in the basal state. Furthermore, we emphasise that Type 2 diabetic patients, though not insulin deficient, may present a significant increase in their fasting levels of ketone bodies.

    Full Text Available Aims and Objectives: To study the finger and palmar dermatoglyphic pattern, establish sexual differences and find out whether a specific dermatoglyphic trait/ features exists in non-insulin dependent diabetes mellitus patients and whether it is significant. Background: Dermatoglyphics is the scientific study of papillary ridges in the palm of the hand and fingers and soles of the feet and toes. The dermal ridges and the configuration which is once formed are not affected by age, development and environmental changes in the post-natal life and so, it has the potential to predict various genetic and acquired disorders with a genetic influence. The etiology of diabetes mellitus is multifactorial with genetics playing an important role. Taking into consideration the genetic predisposition of dermatoglyphics and diabetes mellitus type-2, the study was undertaken to find out correlation between them. Methods: The sample size is 100 patients (60 male and 40female of non-insulin dependent diabetes mellitus and Similarly 100 numbers of normal healthy individual (60 male and 40female, all above 30 years of age group. The patients were selected from the medicine wards and diabetic outpatient department of Civil Hospital Ahmedabad. Dermatoglyphic prints were taken by the “INK METHOD” as described by CUMMINS (1936 and CUMMINS & MIDLO (1961. Observations thus made were compiled and tabulated. Mean and standard deviation were calculated further to test the significance of the differences of observations in different subgroup of study sample. Results: There is statistically significant decrease in whorl pattern is seen in total cases as well as in female of NIDDM cases. Statistically significant difference in loop pattern is seen in D-IV in female (p=0.01 of NIDDM cases and whorl pattern is seen in D-IV in female (p=0.01 and D-III in right hand (p=0.01 of NIDDM cases. Conclusion: Thus from the present study, it appears that there do exists a variation in

    PURPOSE: Microalbuminuria predicts early mortality in non-insulin-dependent-diabetes mellitus patients (NIDDM). Our objective in the present study was to compare and assess the relationship between 24-hour, day and nocturnal ambulatory blood pressure (BP) and urinary albumin excretion rate (UAE) in microalbuminuric and normoalbuminuric NIDDM and in normal control subjects. PATIENTS AND METHODS: In the present cross-sectional study, 24 hour ambulatory BP (daytime BP and nocturnal BP) and HbA1c were compared in microalbuminuric (n = 10) and nonmicroalbuminuric NIDDM patients (n = 10) and in nondiabetic controls (n = 9). None of the patients were taking antihypertensive agents. RESULTS: In the microlbuminuric group, whereas 24 hour and daytime systolic BP differed significantly from control values (P < 0.025 and P < 0.05 respectively), there was no difference between diabetic groups. However, nocturnal systolic BP in the microalbuminuric group was significantly higher than in the normoalbuminuric diabetic patients (139 vs. 125) (P < 0.05) and a significant difference was also found between the NIDDM patients and the control group (139, 125 vs. 114) (P < 0.025). In multiple regression analysis, only nocturnal systolic BP showed a significant relationship with UAE (P < 0.05). CONCLUSIONS: We suggest that the higher nocturnal systolic blood pressure seen in our microalbuminuric NIDDM patients may contribute to the increased morbidity in this group.

    The mechanisms of the diminished hypoglycemic response to insulin in non-insulin-dependent diabetes mellitus (NIDDM) with normal levels of circulating plasma insulin were investigated. Specific binding of mono- 125 I (Tyr A14)-insulin to isolated adipocytes and effects of insulin (5--10,000 microunits/ml) on glucose oxidation and lipolysis were determined simultaneously in subcutaneous adipose tissue of seven healthy subjects of normal weight and seven untreated NIDDM patients with normal plasma insulin levels. The two groups were matched for age, sex, and body weight. Insulin binding, measured in terms of receptor number and affinity, was normal in NIDDM, the total number of receptors averaging 350,000 per cell. Neither sensitivity nor the maximum antilipolytic effect of insulin was altered in NIDDM patients as compared with control subjects; the insulin concentration producing half the maximum effect (ED50) was 10 microunits/ml. As regards the effect of insulin on glucose oxidation, for the control subjects ED50 was 30 microunits/ml, whereas in NIDDM patients, insulin exerted no stimulatory effect. The results obtained suggest that the effect of insulin on glucose utilization in normoinsulinemic NIDDM may be diminished in spite of normal insulin binding to receptors. The resistance may be due solely to postreceptor defects, and does not involve antilipolysis

    Objective: To investigate the morbidity and pattern of osteoporosis in the patients with non-insulin-dependent diabetes mellitus (NIDDM). Methods: Bone density of lumbar vertebra, hip and whole body were measured in 48 patients with NIDDM and in 35 health people aged 30-35 years. All the patients were diagnosed by the standards introduced by the WHO committee in 1985. Outcome were measured by using t text, analysis of variance and coefficient of multiple correlation. Results: Bone density decreased in all the 48 patients with NIDDM, in which 25 (52.1%) patients were diagnosed as osteoporosis. In the patients with NIDDM and osteoporosis, there was a higher rate of the decrease of the bone density of hip (14.1% in male and 15.6% in female respectively) than that of lumbar vertebra. Conclusions: There is a higher morbidity of osteoporosis in the patients with NIDDM. The loss of the bone density might start at the hip. The bone mineral content of whole body lose markedly. And the longer the NIDDM and the menopause exist, the more obvious the decrease of the bone density is. The mechanism of the phenomena is considered as a result of not only the increased loss of calcium and absorption of the bone tissue induced by the secondary hyperparathyroidism, but also the decreased level of the serum insulin-like growth factor, which inhibits the bone formation

    Intra-abdominal liver biopsies were obtained during surgery from fasted obese patients with non-insulin-dependent diabetes mellitus (NIDDM), obese normoglycemic controls, and lean controls. Lipid synthesis was studied in freshly isolated hepatocytes and liver homogenates from the three groups of subjects. Incorporation of 3H2O into the lipids of hepatocytes was determined in the absence and presence of insulin (0.1 mumol/L). The activities of five enzymes involved in fatty acid synthesis, and the incorporation of 14C-glycerol-3-phosphate into lipids were determined in liver homogenates. Basal lipid synthesis by hepatocytes was not different in the three groups of patients. Insulin stimulated lipogenesis by 8% +/- 30% in the lean controls, 33% +/- 8% in the obese controls and 17% +/- 6% in the NIDDM patients. No significant differences in the activities of the five enzymes that are involved in de novo fatty acid synthesis among the three groups of patients were observed. Similarly, incorporation of 14C-glycerol-3-phosphate by liver homogenates, in the presence of saturating or submaximal concentrations of fatty acids, did not differ among the three groups. These results show that under the experimental conditions of this study, including the fasted state of the patients, the basal capacity of liver of NIDDM patients to synthesize fatty acids or glycerides is the same as that of liver from obese and lean controls. Thus, it is likely that an increase in fatty acid flux into a liver with normal lipogenic potential may contribute to the increased synthesis of triglycerides by the liver of these patients in vivo

    Diabetes mellitus has been shown in many studies to be associated with reduced bone mass and an increased risk of fracture. Currently, our understanding of how to use exercise effectively in diabetic patients in prevention of osteoporosis is incomplete and has prompted our interest to identify the type of effective osteogenic exercise. The aim of this study was to compare the changes in handgrip strength and bone metabolism after 6 months between aerobic and resistance exercise training in non-insulin dependent diabetic patients in Jeddah area. One hundred non-insulin dependent diabetic male patients participated in this study and were divided into two equal groups; the first group (A) received aerobic exercise training, where the second group (B) received resistance exercise training. The program consisted of three sessions per week for six months. The mean values of serum calcium and Hand grip strength were significantly increased, while the mean values of parathyroid hormone were significantly decreased in both groups .Also, there were significant differences between mean levels of the investigated parameters in group (A) and group (B) after treatment. Aerobic exercise training on treadmill is appropriate to improve markers of bone metabolism and hand grip strength in non-insulin dependent diabetic patients.

    We performed 123 I-MIBG (MIBG) myocardial scintigraphy twice in patients with non-insulin-dependent diabetes mellitus (NIDDM) to investigate whether MIBG distribution was improved by pertinent clinical control. To determine the influential factors for MIBG distribution, we investigated the association between various clinical parameters and the serial change in MIBG uptake parameters. Twenty NIDDM patients with no cardiac disorders were evaluated. Planar images were taken at 30 minutes (early) and 3 hours (delayed) after MIBG injection. The heart-to-upper-mediastinum uptake ratio (H/M) and washout ratio (WR) were calculated as parameters for estimating cardiac sympathetic function. Patients were divided into two groups, eight in the improved group and twelve in the unimproved group, according to the serial change in H/M. The mean interval between the baseline and the follow up study was 2.1±0.6 year. Differences between the means of the laboratory data in patients in both groups were compared for the baseline and the follow up study by using the paired t-test. As a means of determining the influential factors for a serial change of MIBG uptake, Fisher's exact test was performed to evaluate the association between the serial change in cardiac MIBG parameters and changes in other clinical parameters, such as blood sugar (BS) control, BS control method (insulin therapy), serum cholesterol control, and severity of diabetic complications. We also analyzed the association between the changes in CV R-R (coefficient variance of R-R intervals at rest ECG) or NCV (velocity of posterior tibial nerve) and those of other clinical parameters. Associations among these neurological parameters (MIBG parameters, CV R-R and NCV) were also analyzed. Paired t-tests showed a significant decrease in fasting blood sugar and fructosamine in the improved group in the follow up study compared to those in the baseline study. Nevertheless, Fisher's exact test showed no significant association

    Objective: To approach the correlation between the bone density measured by quantitative CT and the blood sugar level of the aged patients with non-insulin-dependent diabetes mellitus, and observe the effects of the blood sugar level on the bone density. Methods: The lumbar bone densities and the blood sugar levels of 160 aged patients with non-insulin-dependent diabetes mellitus (hyperglycemia group 80 cases, euglycemia group 80 cases ) and the healthy aged people (80 cases) were detected by quantitative CT and serum biochemical detection; the correlation between the blood sugar level and the bone density and the osteoporosis occurrence status of aged people in various groups were analyzed. Results: The bone density in the non-insulin-dependent diabetes and hyperglycemia group was lower than those in normal (control) group and non-insulin-dependent diabetes and euglycemia group (P<0.05); the morbility of osteoporosis in the non-insulin-dependent diabetes and hyperglycemia group was higher than those in normal (control) group and non-insulin-dependent diabetes and euglycemia group (P<0.05); negative correlation was found between the bone density and the blood sugar level (aged male group: r=-0.7382, P=0.0013; aged female group: r=-0.8343, P=0.0007). Conclusion: The blood sugar level affects the bone density of the aged patients with non-insulin-dependent diabetes mellitus; the higher the blood sugar level, the lower the bone density. The non-insulin-dependent diabetes aged patients with hyperglycemia have the liability of osteoporosis. (authors)

In the basal state the immunoreactive mass of GLUT-4 protein both in the crude membrane preparation and in the plasma membrane fraction was similar in NIDDM patients and control subjects. Moreover, in vivo insulin exposure neither for 30 min nor for 4 h had any impact on the content of GLUT-4 protein in plasma...... membranes. With the use of the same methodology, antibody, and achieving the same degree of plasma membrane purification and recovery, we found, however, that intraperitoneal administration of insulin to 7-wk-old rats within 30 min increased the content of GLUT-4 protein more than twofold (P

    The changes in levels of C-P and insulin were investigated in the GT test in rats with non-insulin dependent diabetes mellitus. In order to establish a model of non-insulin dependent diabetes mellitus (NIDDM), the authors injected rats with small dose streptozocoi (i.v.). Two weeks after the injection, the rats developed impaired glucose tolerance (IGT). Then, they were fed with high energy diet for eight weeks to form NIDDM. The results showed that the highest peak time of C-P and insulin in NIDDM was remarkably later than that in normal subjects, the highest peak time was in two hours (P < 0.05). The data suggest that level of C-P could accurately respond to level of insulin, and this experimental non-insulin dependent diabetes mellitus model is ideal

    Full Text Available Background: Patterns of volatile metabolites in urine are important to detect abnormalities associated with diabetes. Present study was conducted to find out the excretion patterns of endogenously produced alcohols in urine for type 2 (Non-Insulin Dependent diabetes mellitus. A cross sectional analytical study was conducted with duration extended from Jan to Mar 2015. Methods: The current study included 40 patients with chronic type 2 diabetes mellitus. In total, 10 sex and age matched subjects with no history of any disease were considered as controls. Blood sugar was estimated by autoanalyzer using standard kit of Merck following manufacturer`s instructions. Urine sugar was quantitatively detected by biuret reagent using titration technique. Urinary alcohol was identified and estimated by gas chromatography. Urinary ketone bodies were estimated by urinary strip. Results: It was observed that level of fasting blood sugar was significantly increased (P<0.001 in patients as compared to their controls. The blood sugar and urinary alcohol in patients were 3.0% and 6.0% respectively. Urinary ketone bodies were found to be 2+. On the other hand urine sugar, alcohol and ketone bodies were not detected in the negative control subjects. Conclusions: It is concluded that urinary alcohol is endogenously produced in patients with type 2 diabetes due to uncontrolled hyperglycemia. However further work is needed to find out the ratio of urinary and blood alcohol which may confirm the present findings.

    A transient rise in hepatic glucose production (HGP) after an oral glucosa load has been reported in some insulin-resistant states such as in obese fa/fa Zucker rats. The aim of this study was to determine whether this rise in HGP also occurs in subjects with established non-insulin-dependent diabetes mellitus (NIDDM). Glucose kinetics were measured basally and during a double-label oral glucose tolerance test (OGTT) in 12 NIDDM subjects and 12 non-diabetic 'control' subjects. Twenty minutes after the glucose load, HGP had increased 73% above basal in the NIDDM subjects (7.29 +/- 0.52 to 12.58 +/- 1.86 mumol/kg/min, P < 0.02). A transient rise in glucagon (12 pg/ml above basal, P < 0.004) occurred at a similar time. In contrast, the control subjects showed no rise in HGP or plasma glucagon. HGP began to suppress 40-50 min after the OGTT in both the NIDDM and control subjects. A 27% increase in the rate of gut-derived glucose absorption was also observed in the NIDDM group, which could be the result of increased gut glucose absorption or decreased first pass extraction of glucose by the liver. Therefore, in agreement with data in animal models of NIDDM, a transient rise in HGP partly contributes to the hyperglycemia observed after an oral glucose load in NIDDM subjects.

    Arterial hypertension is a chronic condition regarded as one of the main risk factors for development of coronary atherosclerosis. As dyslipidemia and reduced glucose tolerance are also risk factors for coronary disease, it is considered important to use antihypertensive drugs having no negative effects on lipid and glucose metabolism when diabetic patients are treated for hypertension. Lacidipine, a new dihydropyridine-like calcium antagonist, has been shown in in vivo and in vitro preclinical studies to possess potent, long-lasting antihypertensive activity. The present study compared the efficacy and safety of once-daily treatment with lacidipine versus nifedipine SR given twice-daily in non-insulin-dependent diabetic patients. Results have shown a similar efficacy of the two treatments: 6 months later, both drugs had reduced blood pressure values [lacidipine from 184.8/105.2 mm Hg to 144.4/87.1 mm Hg; nifedipine slow-release (SR) from 182.3/106.8 mm Hg to 143.6/89.4 mmHg]. However, lacidipine exhibited a lower incidence of adverse events (particularly ankle edema and tachycardia) than nifedipine SR. Finally, both treatments showed no negative effect on metabolic parameters (total cholesterol, high-density lipoprotein cholesterol, triglycerides, and blood glucose).

    To examine the extent to which the defect in insulin action in subjects with non-insulin-dependent diabetes mellitus (NIDDM) can be accounted for by impairment of muscle glycogen synthesis, we performed combined hyperglycemic-hyperinsulinemic clamp studies with [ 13 C]glucose in five subjects with NIDDM and in six age- and weight-matched healthy subjects. The rate of incorporation of intravenously infused [1- 13 C]glucose into muscle glycogen was measured directly in the gastrocnemius muscle by means of a nuclear magnetic resonance (NMR) spectrometer with a 15.5 min time resolution and a 13 C surface coil. The steady-state plasma concentrations of insulin and glucose were similar in both study groups. The mean (±SE) rate of glycogen synthesis, as determined by 13 C NMR, was 78±28 and 183±39 μmol-glucosyl units (kg muscle tissue (wet mass)) -1 min -1 in the diabetic and normal subjects, respectively. The mean glucose uptake was markedly reduced in the diabetic as compared with the normal subjects. The mean rate of non-oxidative glucose metabolism was 22±4 μmol kg -1 min -1 in the diabetic subjects and 42±4 μmol kg -1 min -1 in the normal subjects. When these rates are extrapolated to apply to the whole body, the synthesis of muscle glycogen would account for most of the total-body glucose uptake and all of the non-oxidative glucose metabolism in both normal and diabetic subjects. We conclude that muscle glycogen synthesis is the principal pathway of glucose disposal in both normal and diabetic subjects and that defects in muscle glycogen synthesis have a dominant role in the insulin resistance that occurs in persons with NIDDM.

    To investigate the characteristics of insulin secretion rate (ISR), metabolic clearance rate (MCR-I) and sensitivity and to explore their relationship with obesity in non-insulin-dependent diabetic subjects from multiplex diabetic pedigrees (MDP). Fifteen subjects with normal glucose tolerance and 11 non-insulin-dependent diabetic patients from MDP were included in the study. Frequently sampled intravenous glucose tolerance test (FSIVGTT) was performed. Glucose, insulin (INS) and connecting-peptide (C-P) concentrations were measured. A computer procedure devised by our laboratory was used to calculate the value of ISR at each time point, then MCR-I was acquired. Insulin sensitivity index (SI) was calculated according to minimal model technique about glucose in FSIVGTT. The ISR curve in control group was biphasic, while in non-insulin. In non-insulin-dependent diabetic group, areas under the curves of C-P (AUCC) and ISR level (AUCS) measured during 0 approximately 16 min were 7.9 nmol.min(-1).L(-1) +/- 2.8 nmol.min(-1).L(-1), and 6.1 nmol +/- 2.2 nmol, respectively, which were significantly lower than those in control group 17.7 nmol.min(-1).L(-1) +/- 4.92 nmol.min(-1).L(-1) and 12.3 nmol +/- 3.9 nmol (P < 0.01). The two parameters were slightly higher than those in control group 155 nmol.min(-1).L(-1) +/- 44 nmol.min(-1).L(-1) vs 101 nmol.min(-1).L(-1) +/- 30 nmol.min(-1).L(-1) and 76 nmol +/- 26 nmol vs 54 nmol +/- 20.0 nmol (P < 0.05)measured during 16 approximately 180 min. There was no significant difference, between the two groups about the amount of insulin secretion during 3 hours (82 nmol +/- 28nmol vs 68 nmol +/- 21 nmol, P = 0.2). In control group, there were significant positive correlation, between AUCS, waist-hip ratio (WHR), and body surface area, (BSA) and significant negative correlation between MCR-I, SI and WHR, BSA (P < 0.01), and also between MCR-I and SI. In non-insulin-dependent diabetic group, AUCS were significantly correlated with body mass

    In spite of a large number of drugs showing anti-hyperglycemic activities, none of them have been successful in complete management of diabetes mellitus (DM). Yoga and Ayurveda are the two schools of thought in India, which have a history of curing diseases since thousands of years. Yogic techniques and Ayurvedic herbs have proven their anti-diabetic potential without inducing untoward effects. The present study combines Ayurvedic medication with Yoga techniques as a new approach toward healing DM. To assess the effect of Yoga therapy in the management of non insulin-dependent DM (NIDDM) and to decrease the oral drug dose requirement of guḍūcī ghana Tablet. Thirty known NIDDM patients of both genders, who were on guḍūcī ghana (solidified aqueous extract of Tinospora cordifolia (Willd.) Miers.) tablets from past 2 months as Ayurvedic remedy for DM were selected. Along with guḍūcī ghana administration, the subjects were instructed to follow Yogic procedures including Āsanas, prāṇāyāma, and śuddhi kriyās. The study was conducted for 8 weeks, wherein fasting blood sugar (FBS) and postprandial blood sugar (PPBS) levels along with relief in sign and symptoms were assessed at every 2 weeks intervals, and according to relief in sign and symptoms, tapering of drug dosage was carried out. The obtained data were analyzed statistically by applying paired t-test. The results obtained were promising as the relief in diabetic symptomatology was highly significant in terms of P value. 80.83% reduction in dose of guḍūcī ghana tablets and 7.85% and 8.78% fall in FBS and PPBS levels, respectively, after the complete course of treatment. The obtained P value showed highly significant results.

    Susceptibility to non-insulin-dependent diabetes mellitus (NIDDM) is largely genetically determined. In Pima Indians, obesity, insulin resistance, and a low acute insulin response (AIR) to an intravenous glucose infusion are each predictors of the disease. To ascertain whether these phenotypes are genetically determined, we estimated their familiarity in nondiabetic Pima Indians with a maximum-likelihood method. Percentage body fat (PFAT) was highly familial (h{sup 2} = .76), whereas waist/thigh circumference ratio (W/T ratio) was not significantly familial after controlling for PFAT (h{sup 2} = .16). AIR was also highly familial (h{sup 2} = .80 at 10 min), even after controlling for PFAT and insulin action (h{sup 2} = .70). Insulin action at physiologic plasma insulin concentrations was familial (h{sup 2} = .61) but less so after controlling for PFAT and W/T ratio (h{sup 2} = .38). At maximally stimulating insulin concentrations, insulin action was familial (h{sup 2} = .45) and was less influenced by controlling for PFAT and W/T ratio (h{sup 2} = .49). We conclude that in Pima Indians (1) PFAT and AIR are highly familial traits, (2) central distribution of fat is not a familial trait when controlled for PFAT, (3) 38%-49% of the variance in insulin action, independent of the effect of obesity, is familial, and (4) PFAT, AIR, and insulin action are useful traits to study genetic susceptibility to NIDDM. Because genetic parameter estimates are applicable only to the populations from which they were estimated, it is important to determine whether these estimates of familiarities in Pima Indians can be confirmed in other populations before the utility of these traits in searching for NIDDM susceptibility genes in those populations can be fully advocated. 31 refs., 3 tabs.

    Exercise training has potential benefits for patients with hyperlipidemia and/or non-insulin dependent diabetes mellitus. In nondiabetic, nonobese subjects with hypertriglyceridemia, exercise training alone increased insulin sensitivity, improved glucose tolerance, and lowered serum triglyceride and cholesterol levels. These improvements did not occur when exercise training alone was given to similar patients with impaired glucose tolerance. In severely obese (X = 125 kg) subjects without diabetes melitus, a 600 calorie diet alone decreased glucose and insulin concentrations and improved glucose tolerance but did not increase insulin sensitivity. The addition of exercise training improved insulin sensitivity. Obese, non-insulin dependent diabetes mellitus subjects on sulfonylurea therapy alone increased insulin levels but failed to improve insulin sensitivity or glucose levels. In contrast, the addition of exercise training to this medication resulted in improved insulin sensitivity and lowered glucose levels. We conclude that exercise training has major effects on lowering triglyceride levels in hyperlipidemic subjects and can potentiate the effect of diet or drug therapy on glucose metabolism in patients with non-insulin dependent diabetes mellitus.

    To evaluate nutritional status and blood glucose level according to type of diet followed by elderly (> 65 years old) institutionalised patients with non insulin dependent diabetes mellitus (NIDDM). A data collection questionnaire was administered to the staff of 80 Spanish geriatric facilities participating in this one-day cross-sectional study. Data collected included: age, gender, history of previous glucose control, type of antidiabetic treatment, body mass index (BMI), nutritional risk index (NRI), type of diet with patient's preference, nutritional status evaluation and biochemical parameters. Data from a total of 486 institutionalised elderly people (66.5% female) were collected with a mean +/- SD age of 80.8 +/- 7.5. Had a diabetic diet 93.3% of patients with no gender differences 55.7% were on oral antidiabetic treatment (53.9% females and 58.9% males, ns) and 24.7% on insulin therapy (24.5% females and 26.4% males, ns). Physical activity was presented in 86% of people with no gender differences. Exercise was practiced by people younger, 78.8 +/- 7.9 years, versus walking, 80.4 +/- 7.6 years or resting 82.1 +/- 7.3 years, p nutritional indexes, BMI and NRI, were equivalent in men and in women; 28.5 +/- 10.7 vs 28.1 +/- 7.6 and 103.5 +/- 12.9 vs 104.1 +/- 11.4, respectively. History glucose control was good in 68.8% of the sample with a trend towards significance between sexes (62.7% males, 71.7% females, p = 0.07) and significant differences according to type of diet; 70.7% diabetic versus 37.0% free diet, p = 0.0006). Eating behaviors (appetite and meal completeness) were similar in both males and females and in diabetic or free diet groups. Also, no differences were observed in patient preferences about diet according to type of diet (71% of diabetic patients always or almost always liked their food versus 82% of free diet patients) and either nutritional status (9.3% vs 15.6% in status I, 10.9% vs 12.5% in level II and 79.9% vs 71.9% in status III

    We performed {sup 123}I-MIBG (MIBG) myocardial scintigraphy twice in patients with non-insulin-dependent diabetes mellitus (NIDDM) to investigate whether MIBG distribution was improved by pertinent clinical control. To determine the influential factors for MIBG distribution, we investigated the association between various clinical parameters and the serial change in MIBG uptake parameters. Twenty NIDDM patients with no cardiac disorders were evaluated. Planar images were taken at 30 minutes (early) and 3 hours (delayed) after MIBG injection. The heart-to-upper-mediastinum uptake ratio (H/M) and washout ratio (WR) were calculated as parameters for estimating cardiac sympathetic function. Patients were divided into two groups, eight in the improved group and twelve in the unimproved group, according to the serial change in H/M. The mean interval between the baseline and the follow up study was 2.1{+-}0.6 year. Differences between the means of the laboratory data in patients in both groups were compared for the baseline and the follow up study by using the paired t-test. As a means of determining the influential factors for a serial change of MIBG uptake, Fisher's exact test was performed to evaluate the association between the serial change in cardiac MIBG parameters and changes in other clinical parameters, such as blood sugar (BS) control, BS control method (insulin therapy), serum cholesterol control, and severity of diabetic complications. We also analyzed the association between the changes in CV{sub R-R} (coefficient variance of R-R intervals at rest ECG) or NCV (velocity of posterior tibial nerve) and those of other clinical parameters. Associations among these neurological parameters (MIBG parameters, CV{sub R-R} and NCV) were also analyzed. Paired t-tests showed a significant decrease in fasting blood sugar and fructosamine in the improved group in the follow up study compared to those in the baseline study. Nevertheless, Fisher's exact test showed

    Conclusion: The inhibitory properties of phenolic rich extracts on α-amylase, α-glucosidase, ACE, and Fe2+- and sodium nitroprusside-induced lipid peroxidation in the pancreas could be attributed to the antioxidant properties of the extracts and their phenolic composition. The stronger action of the bound phenolic extract on α-glucosidase may provide the possible bioactivity at the brush border end of the intestinal wall. This study may thus suggest that leaves represent a functional food and nutraceutical in the management of non-insulin dependent diabetes mellitus and hypertension.

Materials and Methods : Four hundred and eight type 2 DM patients (Study Group and 100 non-diabetic patients (Control Group among the age group of 35-75 years were included in the study. The study group was divided based on Glycated hemoglobin levels into well, moderately and poorly controlled. Relevant information regarding age, oral hygiene habits and personal habits was obtained from the patients. Diabetic status and mode of anti-diabetic therapy of the study group was obtained from the hospital records with consent from the patient. Community periodontal index (CPI was used to assess the periodontal status. The results were statistically evaluated. Results : The mean CPI score and the number of missing teeth was higher in diabetics compared with non-diabetics, and was statistically significant ( P=0.000, indicating that prevalence and extent of periodontal disease was more frequent and more severe in diabetic patients. The risk factors like Glycated hemoglobin, duration of diabetes, fasting blood sugar, personal habits and oral hygiene habits showed a positive correlation with periodontal destruction, whereas mode of anti-diabetic therapy showed a negative correlation according to the multiple regression analysis. The odds ratio of a diabetic showing periodontal destruction in comparison with a non-diabetic was 1.97, 2.10 and 2.42 in well, moderately and poorly controlled diabetics, respectively. Conclusion : Our study has made an attempt to determine the association between type 2 DM (NIDDM and periodontal disease in Bangalore city. It was found that type 2 DM (non-insulin-dependent diabetes mellitus [NIDDM] subjects manifested relatively higher prevalence and severity of periodontal disease as compared with non-diabetics.

Four hundred and eight type 2 DM patients (Study Group) and 100 non-diabetic patients (Control Group) among the age group of 35-75 years were included in the study. The study group was divided based on Glycated hemoglobin levels into well, moderately and poorly controlled. Relevant information regarding age, oral hygiene habits and personal habits was obtained from the patients. Diabetic status and mode of anti-diabetic therapy of the study group was obtained from the hospital records with consent from the patient. Community periodontal index (CPI) was used to assess the periodontal status. The results were statistically evaluated. The mean CPI score and the number of missing teeth was higher in diabetics compared with non-diabetics, and was statistically significant (P=0.000), indicating that prevalence and extent of periodontal disease was more frequent and more severe in diabetic patients. The risk factors like Glycated hemoglobin, duration of diabetes, fasting blood sugar, personal habits and oral hygiene habits showed a positive correlation with periodontal destruction, whereas mode of anti-diabetic therapy showed a negative correlation according to the multiple regression analysis. The odds ratio of a diabetic showing periodontal destruction in comparison with a non-diabetic was 1.97, 2.10 and 2.42 in well, moderately and poorly controlled diabetics, respectively. Our study has made an attempt to determine the association between type 2 DM (NIDDM) and periodontal disease in Bangalore city. It was found that type 2 DM (non-insulin-dependent diabetes mellitus [NIDDM]) subjects manifested relatively higher prevalence and severity of periodontal disease as compared with non-diabetics.

    The prevalence of diabetes is rapidly rising all over the globe at an alarming rate. India shelters the highest number of diabetics and is thus known as the 'Diabetes Capital of the World'. The chemical management of diabetes has side effects and hence the present study was undertaken to assess the hypoglycaemic and hypolipidaemic effect of Stevia rebaudiana in patients with type 2 diabetes, non-insulin dependent diabetes mellitus (NIDDM). Its nutritional composition and use as a sweetener substitute were also assessed. Chemical analysis of dried Stevia leaf powder revealed it to be a nutritious herb with a good iron and fibre content. Intervention trials in diabetics revealed that it significantly lowered fasting and post-prandial blood glucose levels. The serum triglycerides and VLDL-C levels were also significantly reduced. Hence it can be said that Stevia can safely be used as an anti-diabetic herb, as a sweetener substitute and may help to prevent cardiovascular diseases in patients with long-standing diabetes. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Studies in humans and animals have lent support to the theory that early undernutrition can promote later obesity, non-insulin dependent diabetes, and coronary heart diseases. The purpose of this study is therefore to investigate the effects of stunting, indicative of previous malnutrition on the increase risk factors for these diseases. The population studied will be 100 school age boys and girls (8-10 y) divided into two groups: stunted (-1.0 to -2.5 z score of height-for-age) but of normal weight-for-height (± 0.5 z score of NCHS); and control having normal height-for-age and weight-for-height (± 0.5 z score of NCHS). Differences in body composition, food intake, blood parameters (fasting glucose and insulin, glycosylated hemoglobin, glucagon, salivary cortisol, triglycerides, high density lipoprotein cholesterol, free-fat acids and IGF-1) and blood pressure will be evaluated.

    Obesity is being recognized as a major public health problem of global significance. The prevalence of obesity is increasing worldwide and also in China. Studies indicated that obesity is the major risk factor for several chronic degenerative diseases including cardiovascular disease, diabetes mellitus, and hypertension. However, the underlying mechanism of obesity development and its relation to non-insulin dependent diabetes mellitus (NIDDM) is not well understood. The major aim of the proposed research study is to investigate the effect of energy intake and expenditure on body composition and obesity development, and to identify obesity and NIDDM risk factors. This study will be conducted in 100 men and women aged 65 living in urban Beijing, China. 2-H and 18-O will be used for body composition and energy expenditure measurements, energy intake by a 3-day food weighted method, physical activity level by questionnaire, insulin determinations by radioimmunoassay (RIA). Demographic data of the subjects will also be collected. We anticipate that the results of this study would help us understand the underlying mechanism of obesity and the relation of obesity to NIDDM in Chinese aging population, so that effective strategies can be identified for prevention and management of obesity and NIDDM.

    To determine whether high-ketogenic very-low-energy diets (VLEDs) can reduce hepatic glucose output (HGO) and hyperglycemia more effectively than can low-ketogenic VLEDs in obese patients with non-insulin-dependent diabetes mellitus (NIDDM), seven patients were treated with a high-ketogenic VLED for 3 wk and were compared with six patients treated with a low-ketogenic VLED. All patients were then crossed over and treated with the alternate diet for another 3 wk. Basal HGO, fasting ketone bodies, and glycemia, insulin, and C-peptide after fasting and an oral-glucose-tolerance test (OGTT) were measured. Before treatment, prediet weight and fasting, OGTT, and HGO measurements were not different between groups. After dieting, weight loss was not different between the groups. However, fasting and OGTT glycemia were lower during treatment with the high-ketogenic VLED than with the low-ketogenic VLED (treatment effect: P ketogenic VLEDs have a more clinically favorable effect on glycemia than do low-ketogenic VLEDs.

    This study was undertaken to examine the effects of aldose reductase inhibitor (ARI) and vitamin B 12 (VB12) on myocardial uptake of iodine-123 metaiodobenzylguanidine (MIBG) in patients with diabetic autonomic disorder. Myocardial scintigraphy using 123 I-MIBG was performed on 20 healthy volunteers (controls) and 56 patients with non-insulin-dependent diabetes mellitus (NIDDM), in order to obtain the heart/mediastinum ratio in the initial (HMi) and the delayed images (HMd), and the washout rate (%WR). Thirty-four of the 56 NIDDM patients could be diagnosed as having diabetic autonomic disorder by evaluating their scintigraphic findings in comparison with the controls. Seventeen of these 34 patients received 150 mg/day of epalrestat (ARI group) in three divided doses before meals, and the other 17 received 1.5 mg/day of mecobalamin (VB12 group) in three divided doses after meals, for 3-5 months. According to the presence or absence of clinical symptoms of autonomic or peripheral somatic nerve disorder, the patients were subclassified into four groups. group 1=patients, with autonomic symptoms or somatosensory disorder in the ARI group; group 2=patients without autonomic symptoms or somatosensory disorder in the ARI group; group 3=patients with autonomic symptoms or somatosensory disorder in the VB12 group; and group 4=patients without autonomic symptoms or somatosensory disorder in the VB12 group. After completion of the treatment, myocardial scintigraphy was performed again. Comparing the results obtained before and after the treatment, it was seen that ARI improved only the HMi in group 1 (P=0.046), whereas VB12 significantly improved HMi in the group 3 (P=0.018) and HMi, HMd and %WR in group 4 (P=0.043, P=0.018 and P=0.043, respectively). We conclude that VB12 is more efficacious than ARI in the treatment of diabetic cardiovascular autonomic disorder. (orig.)

    Myocardial free fatty acid metabolism and left ventricular function were evaluated in 15 middle-aged patients with non-insulin dependent diabetes mellitus (NIDDM) and in 8 healthy control subjects. The study subjects had no evidence of coronary heart disease on the basis of clinical history, exercise ECG or myocardial perfusion scintigraphy. During peak exercise, iodine-123 hepatadecanoic acid (HDA) was intravenously injected. Myocardial activity distribution of 123 I-HDA was measured 10, 30, and 50 min after exercise using single-photon emission tomography (SPET); and then further corrected by free 123 I-iodine. Venous blood samples were drawn for detecting the plasma activity of 123 I. The net extraction of 123 I-HDA into the myocardium was obtained by dividing the corrected tissue 123 I concentration by the integral of the plasma time activity curve. The net extraction was 0.40±0.06 min -1 (mean±SD) patients with NIDDM and 0.38±0.006 min -1 in control subjects (P>0.1), respectively. The faster elimination rate of 123 I-HDA was found in patients with NIDDM (0.029±0.008 min -1 ) than in control subjects (0.022±0.004 min - 1); P 123 I-HDA and the change of LVEF, as well as with exercise load (r=0.68; P<0.01). In conclusion, evidence of an increased fatty acid utilization and triglyceride synthesis rate was observed in the diabetic myocardium. (orig.)

    Objective: Determination of plasma N-terminal pro-brain natriuretic peptide [NT-proBNP (1-76)] levels is useful for the diagnosis of heart failure. Present study was to investigate the significance of changes of plasma NT-proBNP (1-76) levels in patients with acute myocardial infarction (AMI), unstable angina pectoris (UAP) and non-insulin-dependent diabetes (NIDD). Methods: Plasma NT-proBNP (1-76) levels were determined with RIA in 32 patients with AMI, 27 patients with UAP, 12 patients with NIDD and 20 controls. Moreover, 16 of the 32 AMI patients underwent percutaneous transluminal coronary angioplasty (PTCA) and plasma (1-76) levels were again determined 12hr before and 12hr after the procedure. Results: The plasma NT-proBNP (1-76) levels in controls were 360.8 ± 57.3 pg/ ml with no significant difference between the sexes. In patients with AMI, UAP and NIDD, NT-proBNP (1-76) levels were 554.1 ± 195.9 pg/ml, 525.7 ± 199.1 pg/ml and 552.6 ± 141.9 pg/ml respectively; all of them were significantly higher than those in controls (P 0.05). Conclusion: The plasma NT-proBNP (1-76) levels in patients with AMI, UAP and NIDD were increased significantly and the result suggested that NT-proBNP (1-76) might be a useful risk marker for these diseases.

    Myocardial free fatty acid metabolism and left ventricular function were evaluated in 15 middle-aged patients with non-insulin dependent diabetes mellitus (NIDDM) and in 8 healthy control subjects. The study subjects had no evidence of coronary heart disease on the basis of clinical history, exercise ECG or myocardial perfusion scintigraphy. During peak exercise, iodine-123 hepatadecanoic acid (HDA) was intravenously injected. Myocardial activity distribution of {sup 123}I-HDA was measured 10, 30, and 50 min after exercise using single-photon emission tomography (SPET); and then further corrected by free {sup 123}I-iodine. Venous blood samples were drawn for detecting the plasma activity of {sup 123}I. The net extraction of {sup 123}I-HDA into the myocardium was obtained by dividing the corrected tissue {sup 123}I concentration by the integral of the plasma time activity curve. The net extraction was 0.40+-0.06 min{sup {minus}1} (mean+-SD) patients with NIDDM and 0.38+-0.006 min{sup {minus}1} in control subjects (P>0.1), respectively. The faster elimination rate of {sup 123}I-HDA was found in patients with NIDDM (0.029+-0.008 min{sup {minus}1}) than in control subjects (0.022+-0.004 min{sup {minus}1}); (P<0.01). There no statistically significant difference in left ventricular ejection fraction (LVEF) at rest between patients with NIDDM (53+-9%) and control subjects (56+-2%), whereas the increase of LVEF during exercise remained lower in patients with NIDDM (3.4+-8.2) than in control subjects (11.8+-5.8%; P<0.025). A significant correlation (r=0.64; P<0.01) was found between the net extraction of {sup 123}I-HDA and the change of LVEF, as well as with exercise load (r=0.68; P<0.01).

    Exercise training has been shown to be effective in preventing the development of non-insulin-dependent diabetes mellitus (NIDDM) in a model rat (Otsuka-Long-Evans-Tokushima Fatty [OLETF]). For determination of how long a preventive effect of exercise training against the development of NIDDM lasts in this model, six male OLETF rats each were assigned to training (1) for a whole experimental period, from 7 to 28 weeks of age (E-E); (2) for the first half of the period, from 7 to 15 weeks of age (E-S); and (3) for the second half of the period, from 16 to 28 weeks of age (S-E). In addition, eight male OLETF rats were given no exercise during the experimental period (S-S). At 28 weeks of age, E-E, E-S, S-E, and S-S rats, weighed averages of 514, 542, 557, and 669 g and had abdominal fat deposits of 13.9, 21.3, 38.2, and 76.0 g, respectively. At 28 weeks of age, the cumulative incidence of NIDDM in S-S was 100%, while none of the trained rats were diabetic. The glucose infusion rate (GIR) during a hyperinsulinemic euglycemic clamp test, an index of insulin sensitivity, in the E-E group was significantly greater than that in the S-S group. The values in the E-S and S-E groups were slightly, but not significantly, less than that in the E-E group. Morphologic studies on the pancreas of E-E rats and S-E rats showed minimal changes of islets, whereas sections of islets from E-S rats appeared slightly enlarged and fibrotic, although significantly less than those of islets of S-S rats. These results demonstrate that the preventive effect of excercise training against the development of NIDDM lasts for at least 3 months after the cessation of exercise in this model.

    The objectives of this clinical study using iodine-123 metaiodobenzylguanidine (MIBG) scintigraphy were (a) to evaluate cardiac sympathetic denervation in non-insulin-dependent diabetes mellitus (NIDDM) patients with and without hypertension and (b) to investigate the relation between cardiac sympathetic denervation and prognosis in NIDDM patients. We compared clinical characteristics and MIBG data [heart to mediastinum (H/M) ratio and % washout rate (WR)] in a control group and NIDDM patients with and without hypertension. MIBG scintigraphy was performed in 11 controls and 82 NIDDM patients without overt cardiovascular disease except for hypertension (systolic blood pressure {>=}140 and/or diastolic blood pressure {>=}90 mmHg). After MIBG examination, blood pressure was measured regularly in all NIDDM patients. There were significant differences between 65 normotensive and 17 hypertensive NIDDM patients with respect to age (55{+-}11 vs 63{+-}12 years, respectively, P<0.05), prevalence of diabetic retinopathy (12% vs 35%, respectively, P<0.05) and systolic blood pressure (120{+-}12 vs 145{+-}16 mmHg, respectively, P<0.001). The H/M ratio in hypertensive NIDDM patients was significantly lower than in the control group (1.81{+-}0.29 vs 2.27{+-}0.20, respectively, P<0.01). During the follow-up period (18{+-} 12 months), 17 NIDDM patients newly developed hypertension after MIBG examination.

    Insulin-dependent diabetes mellitus (IDDM) is a polygenic disorder with an autoimmune basis for disease development. In addition to HLA, a second susceptibility locus for IDDM has been identified to lie in the major histocompatibility class III region. MIC-A is located in the MHC class III region and is expressed by monocytes, keratinocytes, and endothelial cells. Sequence determination of the MIC-A gene identifies trinucleotide repeat (GCT) microsatellite polymorphism in exon 5. Five alleles with 4, 5, 6, and 9 repetitions of GCT or 5 repetitions of GCT with 1 additional nucleotide insertion (GGCT) are identified. The alleles are A4, A5, A5.1, A6, and A9. The aim of our study was to find the association of MIC-A alleles with IDDM, malnutrition-modulated diabetes mellitus (MMDM), and non-insulin-dependent diabetes mellitus (NIDDM) patients. IDDM (n = 52), MMDM (n = 41), NIDDM (n = 212), and healthy controls (n = 73) from Cuttack, in eastern India, were studied. Of the 212 NIDDM patients analyzed, 96 of them were found to be positive for either GAD65 or IA-2 antibodies. Autoantibodies to GAD65 and IA-2 were measured by radioligand binding assay using (35)S-labeled recombinant human GAD65 and IA-2 in an in vitro transcription/translation system. Autoantibody-positive NIDDM patients (n = 96) and adult healthy controls for NIDDM (n = 113) were also compared. These autoantibody-positive NIDDM patients are considered as slow-onset IDDM or latent autoimmune diabetes in adults (LADA) patients. The samples were analyzed for MIC-A by PCR amplification, and fragment sizes were determined in an ABI prism DNA sequencer. The results of the MIC-A typing are: allele 9 of MIC-A is positively associated (OR 3.62; P IDDM (OR 2.64; P IDDM in eastern India. MIC-A is important in the pathogenesis of MMDM patients from Cuttack. MIC-A alleles distinguish acute-onset IDDM from slow-onset IDDM, indicating that this molecule may be important for delaying the onset of IDDM with the result

    Full Text Available Background and Objectives: Diabetes mellitus is among the most common causes of mortality in the world and an important risk factor for chronic kidney disease, foot amputation, ischemic heart disease and blindness among older adults. Diabetic patients mostly develop hyperlipidemia, which can result in cardiovascular diseases. Patient’s knowledge, attitude and practices toward diet are the core center for diabetes control and affect their metabolic control and complications. In the present study, we measured nutritional knowledge, attitude and practices and their relations to serum lipids, HbA1C, and fasting blood glucose in diabetic patients of Boirahmad County, southwest of Iran, where many people encounter increasing prevalence of diabetes. Materials and Methods: 198 IDDM patients from the rural and urban areas of Boirahmad County were invited to the health centers to be checked for their fasting blood glucose, serum total cholesterol, serum HDL cholesterol, serum triglyceride and also serum glycosylated hemoglobin. Their knowledge, attitude, and practices toward the diabetic diet were assessed using a validated questionnaire. The obtained scores were classified into three categories (Poor, average, and Good to show their knowledge, attitude and practice levels, and the serum parameters were compared between the levels to show the relevancies. Results: Our data showed that the patients’ knowledge and attitude on diabetic nutrition are mostly at the average level (79.3% and 47.1%, respectively but their practice scores are mostly at the poor level (43.8%, and just a minor proportion of the patients are at the appropriate levels (15.3, 33, and 23.1% of knowledge, attitude and practices, respectively. In addition, we found a significant reverse relationship between the patients’ nutritional knowledge and  serum HbA1C (p=0.003, and also between their attitude and serum triglyceride (p<0.05. Conclusions: Our data suggest that the knowledge

    Full Text Available Food and Drug Administration (FDA approved bromocriptine mesylate, a quick release formulation, 0.8 mg tablets, as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Bromocriptine products were previously approved by the FDA for the treatment of pituitary tumors and Parkinson′s disease. Bromocriptine is thought to act on circadian neuronal activities within the hypothalamus to reset abnormally elevated hypothalamic drive for increased plasma glucose, triglyceride, and free fatty acid levels in fasting and postprandial states in insulin-resistant patients. Adverse events most commonly reported in clinical trials of bromocriptine included nausea, fatigue, vomiting, headache, and dizziness. These events lasted a median of 14 days and were more likely to occur during initial titration of the drug. Due to novel mechanism of action, single daily dose, and lower incidence of stroke, myocardial infarction and vascular events, bromocriptine may act as landmark in treatment of type 2 diabetes.

    Punica granatum L., (Family: Punicaceae) is used in Indian Unani medicine for treatment of diabetes mellitus. Therefore, the present study was done to evaluate the antidiabetic and antihyperlipidemic effects of ethanolic extract of leaves of P. granatum in alloxan-induced diabetic rats. Healthy Wistar albino rats (100-150 g) were divided into four groups of six animals each. Groups A and B received normal saline [(10 ml/kg/day/per oral (p.o.)]; group C received ethanolic extract of leaves of P. granatum (500 mg/kg/p.o.); and group D received glibenclamide (0.5 mg/kg/day/p.o.). The extracts were given for 1 week in all groups. To induce diabetes, alloxan 150 mg/kg, intraperitoneal (i.p.) single dose was administered to groups B, C, and D. Blood glucose and serum lipids [Total Cholesterol (TC), Triglycerides (TG), Low Density Lipoproteins (LDL), and High Density Lipoproteins (HDL)] and the atherogenic index were estimated after one week. For mechanism of antidiabetic action glycogen estimation on the liver, cardiac and skeletal muscle, and intestinal glucose absorption was done. Group B showed a significant (Pgranatum leaves possess significant antidiabetic and antihyperlipidemic activity.

    Full Text Available It is well known that under the influence of regular, individually measured aerobic physical activity, it is possible to raise the biological efficiency of insulin by several mechanisms: by increasing the number of insulin receptors, their sensitivity and efficiency, as well as by increasing glucose transporters GLUT-4 on the level of cell membrane. The aim of this research was to examine whether decreased insulin resistance could be achieved under the influence of the program of individually measured aerobic physical activity in the 2-week period, in the obese type 2 diabetes patients with the increased aerobic capacity (VO2max. In 10 type 2 diabetes patients 47.6 ± 4.6 years of age (group E, in the 14-days period, program of aerobic training was applied (10 sessions - 35 min session of walking on treadmill, intensity 60.8 ± 5.7% (VO2max, frequency 5 times a week , as well as 1 600 kcal diet. At the same time, other 10 type 2 diabetes patients 45.9 ± 5.5 years of age (group C were on 1 600 kcal diet. Before and after this period the following was measured in both groups: insulin sensitivity (M/I by the method of hyperinsulin euglycemic clamp, and (VO2max by Astrand test on ergocycle. In contrast to the group C, in the second testing of E group subjects a significant increase was obtained in M/I (1.23 ± 0.78 vs. 2.42 ± 0.95 mg/kg/min/mU p<0.001, 96.75% as well as the increase of (VO2max (26.34 ± 4.26 vs. 29.16 ± 5.01 ml/kg/min p<0.05, 10.7%. The results had shown that 2-week program of aerobic training had had significant influence on the increased aerobic capacity and insulin sensitivity in the tested patients.

    Diabetes mellitus is associated with an increase in sialic acid concentration along with other complications. Sialic acid changes in NIDDM patients were investigated following bitter melon (55 ml/24h) and rosiglitazone (4 mg/24h) treatment. A total of 25 patients of both sexes were used in each experimental group. Patients following bitter melon treatment showed no significant difference of serum sialic acid (57.95+/-4.90 vs. 57.6+/-5.56 mg/dl, p=0.17) and serum glucose concentration (93.7+/-9.63 vs. 88.35+/-6.31 mg/dl, p=0.78) as compared to control subjects. However, the concentration of total cholesterol was significantly high in these patients as compared to control subjects (192+/-14.23 vs. 170.6+/-15.1mg/dl, pdiabetes and its related complications as compared to rosiglitazone.

    The metabolic effects of glucagon leading to hyperglycaemia are well recognised. However, the spasmolytic properties of glucagon have only relatively recently been utilised in clinical medicine. The marked hyperglycaemia accompanying the smooth muscle relaxant action of glucagon has led to the development of smaller peptides derived from glucagon which may retain the spasmolytic effects without the metabolic consequences. This study compares the metabolic and hormonal response to one such pep...

    Background: Previous studies by us and others have shown higher energy conservation mechanisms in marginally stunted Brazilian children such as, lower resting energy expenditure, lower fat oxidation, higher susceptibility to gain weight-for-height associated with a higher prevalence of stunted - obese subjects. Hypothesis: previous malnutrition as judged by height-for-age could be associated with alterations in fat patterning, circulating hormones such as insulin and IGF-1. In addition, previous malnutrition could be also associated with alterations in plasma lipid profiles, such as high triglycerides, low high-density lipoprotein cholesterol levels and hypertension. Sample and Methods: We recruited a population of 58 girls and boys with 11-14 years of age from the shantytown population in Sao Paulo, Brazil. Half of this population was of normal weight and height, and the other half was stunted. More than 300 children from to 11 years old were screened to participate in the study and were eligible if they had weight-for-height Z scores (WHZ) of -2 to +2 according to the IVCHS standards. Children recruited for the stunted group (n=28) had height-for-age (HAZ) ≤-1.5 Z score and those for the non-stunted group (n=30) had HAZ >1.50. In addition, the two groups were selectively recruited to assure group similarities in mean age and WH. General anthropometry, blood sampling for fasting insulin, glucose, glycosylated hemoglobin, triglycerides, high-density lipoprotein cholesterol, low-density cholesterol and IGF-1 were made as well as blood pressure. Results: Ninety two percent of the population had low values of IGF-1 indicating impaired growth. Stunted boys and girls had delayed pubertal stages. Lower fasting insulin levels and lower beta cell production according to HAM analysis in comparison to non-stunted children were found, after adjustment for differences in pubertal stages. In addition, a positive association was found between fasting insulin with age for the stunted group. Body mass index was positively associated with fasting insulin, Homa-beta cell production and HOAM-insulin sensitivity in both nutritional groups. Almost all children showed diastolic blood pressure values above the 50th percentile and 41% of boys and 28% of girls had their values above the 90th percentile, indicating important alterations according to the reference curve adjusted by stature. Conclusions: these preliminary results indicate that both the stunted and non-stunted boys and girls had impairment in growth as seen by the IGF-1 levels. Therefore, it seems that living in shantytowns, as all these children do, may impair growth potential. In addition the present stunted children showed a series of metabolic alterations in comparison to non-stunted ones, as seen by lower fasting insulin, lower Betacell production. On the other hand, diastolic blood pressure was high for the majority of the study population. Working Progress: - To continue the measurements of hormonal parameters (salivary cortisol, thyroid hormones); - To continue the analysis of body composition; - To compare results of body composition with carbohydrate and lipid profile and blood pressure. Future Plan: - To do the follow-up analysis comparing weight and percent of fat gain between stunting and non-stunting groups; - To include another group of children who had caught-up in height after nutritional intervention; - To compare energy expenditure at baseline by doubly labeled water method with weight and percent of fat gain among the stunted and non-stunted groups. Main Findings: - Whole sample in comparison to reference curves: - Lower 1GF-1 levels 92% of the children); - Higher diastolic blood pressure (100% of the children above 50th and 41% of boys and 28% of girls above 90th); - Differences between stunting and non-stunting groups: - Stunted children had delayed Tanner stages; - Lower fasting insulin; - Lower Beta cell production. Implications: - Living in shantytowns in the city of Sao Paulo impairs growth; - High prevalence of high diastolic blood pressure in poor kids was found; - Stunted children showed alterations in insulin profile indicating impairment in Beta cell production and lower insulin levels. - Isotopic Techniques used: - Radioimmunoassay; - Doubly Labeled Water; - DEXA.

    Diabetic nephropathy (DN) is one of the complications of diabetes and is now the most common cause of end-stage renal disease. Fructose is a simple carbohydrate that is present in fruits and honey and is used as a sweetener because of its sweet taste. Fructose has been reported to have the potential to progress diabetes and DN in humans even though fructose itself does not increase postprandial plasma glucose levels. In this study, we investigated the effects of high fructose intake on the kidney of the Spontaneously Diabetic Torii (SDT) rats which have renal lesions similar to those in DN patients and compared these with the effects in normal SD rats. This study revealed that a 4-week feeding of the high fructose diet increased urinary excretion of kidney injury makers for tubular injury and accelerated mainly renal tubular and interstitial lesions in the SDT rats but not in normal rats. The progression of the nephropathy in the SDT rats was considered to be related to increased internal uric acid and blood glucose levels due to the high fructose intake. In conclusion, high fructose intake exaggerated the renal lesions in the SDT rats probably due to effects on the tubules and interstitium through metabolic implications for uric acid and glucose.

    Full Text Available Spontaneously Diabetic Torii Leprfa (SDT fatty rat, established by introducing the fa allele of the Zucker fatty rat into SDT rat genome, is a new model of obese type 2 diabetes. Both male and female SDT fatty rats show overt obesity, and hyperglycemia and hyperlipidemia are observed at a young age as compared with SDT rats. With early incidence of diabetes mellitus, diabetic complications, such as nephropathy, retinopathy, and neuropathy, in SDT fatty rats were seen at younger ages compared to those in the SDT rats. In this paper, we overview pathophysiological features in SDT fatty rats and also describe new insights regarding the hematology, blood pressure, renal complications, and sexual dysfunction. The SDT fatty rats showed an increase of leukocytes, especially the monocyte count, prominent hypertension associated with salt drinking, end-stage renal disease with aging, and hypogonadism. Unlike other diabetic models, the characteristic of SDT fatty rat is to present an incidence of diabetes in females, hypertension, and retinopathy. SDT fatty rat is a useful model for analysis of various metabolic disorders and the evaluation of drugs related to metabolic disease.

    Full Text Available Diabetes mellitus occurs spontaneously in dogs. Although canine diabetes shares many features with human type-1 diabetes, there are differences that have cast doubt on the immunologic origin of the canine disease. In this study, we examined whether peripheral immune responses directed against islet antigens were present in dogs with diabetes. Routine diagnostics were used to confirm diabetic status, and serum samples from dogs with (N = 15 and without (N = 15 diabetes were analyzed for the presence of antibodies against islet antigens (insulin, glutamic acid decarboxylase, insulinoma-associated protein tyrosine phosphatase, and islet beta-cell zinc cation efflux transporter using standard radioassays. Interferon-γ production from peripheral blood T cells stimulated by porcine insulin and by human insulin was tested using Elispot assays. Anti-insulin antibodies were detectable in a subset of diabetic dogs receiving insulin therapy. Pre-activated T cells and incipient insulin-reactive T cells in response to porcine or human insulin were identified in non-diabetic dogs and in dogs with diabetes. The data show that humoral and cellular anti-insulin immune responses are detectable in dogs with diabetes. This in turn provides support for the potential to ethically use dogs with diabetes to study the therapeutic potential of antigen-specific tolerance.

    Impaired diabetic wound healing is an important issue in diabetic complications. The present study aims to evaluate the protective effect on glycemic control against impaired diabetic wound healing using a diabetic rat model. We investigated the wound healing process and effect on the impaired wound repair by glycemic control in the Spontaneously Diabetic Torii (SDT) fatty rat, which is a new animal model of obese type 2 diabetes and may be a good model for study impaired wound healing. Male SDT fatty rats at 15 weeks of age were administered orally with sodium glucose co-transporter (SGLT) 2 inhibitor for 3 weeks. Wounds were induced at 2 weeks after SGLT 2 inhibitor treatment, and the wound areas were periodically examined in morphological and histological analyses. The SDT fatty rats showed a delayed wound healing as compared with the normal rats, but a glycemic control improved the impaired wound healing. In histological analysis in the skin of SDT fatty rats showed severe infiltration of inflammatory cell, hemorrhage and many bacterial masses in the remaining and slight fibrosis of crust on skin tissue . Thought that this results skin performance to be a delay of crust formation and regeneration of epithelium; however, these findings were ameliorated in the SGLT 2 inhibitor treated group. Glycemic control is effective for treatment in diabetic wounds and the SDT fatty rat may be useful to investigate pathophysiological changes in impaired diabetic wound healing.

    The prevalence and progression of vascular complications of spontaneous diabetes mellitus (DM) in dogs have not been described. To investigate the effects of duration of disease, as estimated by time since DM diagnosis, and glycemic control on prevalence of systemic hypertension, proteinuria, and diabetic retinopathy in dogs with spontaneous DM. Seventeen client-owned dogs with spontaneous DM. Prospective, longitudinal observational study. Dogs with DM of less than 1 year's duration were recruited and evaluated once every 6 months for 24 months. Recorded measures included indirect BP, urine albumin, protein and creatinine concentrations, serial blood glucose and serum fructosamine concentrations, ophthalmic examination, and a standardized behavioral questionnaire. Eleven dogs completed the 2-year follow-up period, during which the highest recorded prevalence of systolic and diastolic hypertension was 55 and 64%, respectively. Prevalence of microalbuminuria and elevated urine protein:creatinine ratio (UPC) ranged up to 73 and 55%, respectively. Prevalence of retinopathy ranged up to 20%. No significant effect of time since DM diagnosis or glycemic control was detected for any of the measures examined. Additionally, no significant associations between BP, urine albumin concentration, UPC and retinopathy were detected. With the exception of proteinuria, which was substantial in some cases, clinically deleterious diabetic vascular complications were not identified in dogs in this study.

    Full Text Available The Spontaneously Diabetic Torii Leprfa (SDT fatty rat is a novel type 2 diabetic model wherein both male and female rats develop glucose and lipid abnormalities from a young age. In this study, we investigated gender differences in abnormalities and related complications in SDT fatty rats. Food intake was higher in males compared to female rats; however, body weight was not different between genders. Progression of diabetes, including increases in blood glucose and declines in blood insulin, was observed earlier in male rats than in females, and diabetic grade was more critical in male rats. Blood lipids tended to increase in female rats. Gonadal dysfunction was observed in both male and female rats with aging. Microangiopathies, such as nephropathy, retinopathy, neuropathy, and osteoporosis, were seen in both genders, and pathological grade and progression were more significant in males. Qualitative and quantitative changes were observed for metabolic disease gender differences in SDT fatty rats. The SDT fatty rat is a useful model for researching gender differences in metabolic disorders and related diseases in diabetes with obesity.

    To describe the clinical presentation and surgical outcome of diabetic canine patients with cataracts and preoperative spontaneous lens capsule rupture. A total of 20 dogs and 40 eyes were included in the retrospective evaluation. The patients' ages ranged from 5 to 14 years (mean 8.5 years). All dogs had clinical diabetes mellitus, with the duration since diagnosis ranging from 30 to 240 days (mean 123 days). Cataracts were bilateral and noted to have been present for 14-112 days (mean 39 days). Of the 40 eyes affected with cataracts, 30 had a spontaneous rupture of the lens capsule prior to surgery. The capsular rupture was diagnosed on clinical examination in 28/30 eyes and was noted intraoperatively in 2/30. The location of the capsular rupture was equatorial in 29/30 and posterior in 1/30 eyes. Surgery was performed in 38/40 eyes, with one case lost to follow-up without surgical intervention. Prior to surgery, routine diagnostic ophthalmic examination, ocular ultrasound, electroretinography, and systemic evaluation were performed in all dogs. Surgical procedures included phacoemulsification in 28/40 eyes, with IOL placement performed in 20/28 eyes. Intrascleral prosthesis placement or enucleation was performed in 8/40 and 2/40 eyes, respectively, due to a significantly reduced ERG or secondary glaucoma. The duration of clinical follow-up (19/20 dogs) ranged from 1 to 36 months (mean 12.9 months). All eyes that had cataract surgery with or without IOL placement were sighted at the time of the last follow-up examination. Spontaneous lens capsule rupture associated with diabetes mellitus, cataract and rapid lens intumescence occurs in the dog. Early surgical intervention, prior to secondary complications of glaucoma and loss of retinal function, is associated with a favorable outcome.

  19. Exposure to bisphenol A, but not phthalates, increases spontaneous diabetes type 1 development in NOD mice

    Full Text Available Type 1 diabetes mellitus (T1DM is an autoimmune destruction of insulin producing pancreatic beta-cells due to a genetic predisposition and can be triggered by environmental factors. We have previously shown that bisphenol A (BPA accelerates the spontaneous development of diabetes in non-obese diabetic (NOD mice. Here, we hypothesized that oral exposure to a mixture of the endocrine disruptors BPA and phthalates, relevant for human exposure, would accelerate diabetes development compared to BPA alone. NOD mice were exposed to BPA (1 mg/l, a mixture of phthalates (DEHP 1 mg/l, DBP 0.2 mg/l, BBP 10 mg/l and DiBP 20 mg/l or a combination of BPA and the phthalate mixture through drinking water from conception and throughout life. Previous observations that BPA exposure increased the prevalence of diabetes and insulitis and decreased the number of tissue resident macrophages in pancreas were confirmed, and extended by demonstrating that BPA exposure also impaired the phagocytic activity of peritoneal macrophages. None of these effects were observed after phthalate exposure alone. The phthalate exposure in combination with BPA seemed to dampen the BPA effects on macrophage number and function as well as diabetes development, but not insulitis development. Exposure to BPA alone or in combination with phthalates decreased cytokine release (TNFα, IL-6, IL-10, IFNγ, IL-4 from in vitro stimulated splenocytes and lymph node cells, indicating systemic changes in immune function. In conclusion, exposure to BPA, but not to phthalates or mixed exposure to BPA and phthalates, accelerated diabetes development in NOD mice, apparently in part via systemic immune alterations including decreased macrophage function.

    Recent clinical reports have suggested that hypertension accelerates the progress of diabetic nephropathy and retinopathy, whereas antihypertensive treatments may retard them. Thus, the effect of antihypertensive treatment in diabetes mellitus with hypertension was evaluated in rats. A model of diabetes mellitus with hypertension has been developed in spontaneously hypertensive (SHR) rats by unilateral nephrectomy and streptozotocin (STZ, 30 mg/kg, i.v. treatment). The rats were treated with four antihypertensive drugs orally for 12 weeks thereafter. STZ treatment induced chronic hypeglycaemia (300-400 mg/dl), decreased body weight and heart rate, and caused vascular changes of ophthalmic fundi and cataracta. The kidney of these rats showed proliferative changes such as periarteritis nodosa, hyperplasia, or fibronecrosis of the arterioles, exudative changes, mesangial proliferation, or thickening of the basement membrane of the glomeruli. Enalapril (10 mg/kg per day) and remipril (Hoe 498) (1 mg/kg per day), converting enzyme inhibitors, or arotinolol (20 mg/kg per day), a beta-adrenoceptor blocking drug, decreased blood pressure, prevented the development of renal and ocular lesions, and tended to increase creatinine clearance. Nisoldipine (3 mg/kg per day), a calcium-entry blocking drug, tended to decrease blood glucose, and prevented the decrease of body weight and development of ocular lesions. In conclusion, antihypertensive treatments were effective in preventing the progress of diabetic retinopathy and nephropathy, and renal insufficiency in this animal model.

    Full Text Available The carotid bodies from adult spontaneous insulin-dependent diabetic rats (strain BB/S were perfusion-fixed at normal arterial blood pressure with 3% phosphate-buffered glutaraldehyde and compared with the organs from control rats (strain BB/Sc prepared in the same way. Serial 5-µm sections were cut, stained, and using an interactive image analysis system, were analysed to determine the volumes of the carotid body and its vascular and extravascular compartments. There was no evidence of systemic arterial disease in the carotid stem arteries in either group of animals, and the microvasculature of the organs appeared normal by light microscopy. The volume of the carotid body was unchanged 3 months after the onset of diabetes but was increased at 6 months. The total vascular volume of the organ was unchanged, but the volume of the small vessels (5-12 µm was increased. In the control group the small vessels comprised 5% of the total volume of the carotid body, or about 44% of the vascular compartment. The percentage of small vessels increased at 3 months in the diabetic group, but had returned to normal at 6 months. The extravascular volume followed the same pattern as the total carotid body volume and so did not change appreciably when expressed as a percentage of the total volume of the organ. The increase in size of the carotid body in diabetic rats is due, therefore, to an augmented extravascular volume. In one diabetic specimen the carotid sinus nerve showed signs of diabetic neuropathy, axonal swelling and intramyelinic oedema. The clinical implications of these results are discussed.

    Prediabetes, a high-risk state for developing diabetes showing impaired glucose tolerance but a normal fasting blood glucose level, has an increasing prevalence worldwide. However, no study investigating the prevention of impaired glucose tolerance at the prediabetic stage by anti-diabetic functional foods has been reported. Thus, the present study aimed to evaluate the anti-prediabetic effect of rose hip in a prediabetic rat model. Spontaneously diabetic Torii (SDT) rats were supplemented with hot-water extract of rose hip at a dose of 100 mg kg -1 body weight day -1 for 12 weeks. The results obtained showed that the supplementation of rose hip extract improved impaired glucose tolerance, promoted insulin secretion, preserved pancreatic beta-cell function and suppressed plasma advanced glycation end-products formation of methylglyoxal-derived hydroimidazolone (MG-H1) residue and N ϵ -carboxymethyl-lysine residues (e.g. MG-H1, control: 465.5 ± 43.8 versus rose hip: 59.1 ± 13.0 pmol mg protein -1 , P rose hip could exert an anti-prediabetic effect in a rat model. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    2013-01-01

    Full Text Available Objective: to improve the results of spontaneous labor in female patients with diabetes mellitus (DM. Subjects and methods. The results of physiological labor analgesia were analyzed in 140 patients. The parturients were divided into 3 groups: 1 40 parturients in whom analgesia was performed by the intravenous administration of promedol; 2 40 parturients in whom analgesia was done by the fractional administration of 0.2% ropivacaine hydrochloride into the epidural space; 3 40 parturients in whom analgesia was carried out with intravenous paracetamol 2000—3000 mg. In all the patients, the investigators estimated central hemodynamic parameters by echocardiography, the efficiency of labor analgesia according to the scale described by N. N. Rasstrigina and B. V. Shnaider, as well as blood glucose levels, fetal status by a cardiotocographic technique, and neonatal status by Apgar scores at 1 and 5 minutes of life. Results. Analgesia quality assessment established that the best analgesic effect was achieved in the patients in Group 2 where 75.0% of the parturients had 8—10 scores. A comparative analysis of carbohydrate metabolic parameters also ascertained that the most steady-state and physiological glycemic level was recorded in Group 2 patients throughout the study. In addition, epidural analgesia versus other analgesic techniques provides the most steady-state hemodynamic parameters during labor, which promotes improved labor and has a beneficial effect on fetal and neonatal states. Conclusion. Glycemic levels during labor and delivery can be optimized in patients with DM only if adequate analgesia is achieved. By ensuring adequate labor analgesia, epidural analgesia normalizes glycemic and central hemodynamic parameters, favors elimination of delivery abnormalities, and has a beneficial effect on fetal and neonatal states. Key words: epidural analgesia, diabetes mellitus, spontaneous labor.

    2001-09-01

    We describe a new Type I (insulin-dependent) diabetes mellitus rat model (LEW.1AR1/Ztm-iddm) which arose through a spontaneous mutation in a congenic Lewis rat strain with a defined MHC haplotype (RT1.Aa B/Du Cu). The development of diabetes was characterised using biochemical, immunological and morphological methods. Diabetes appeared in the rats with an incidence of 20 % without major sex preference at 58+/-2 days. The disease was characterised by hyperglycaemia, glycosuria, ketonuria and polyuria. In peripheral blood, the proportion of T lymphocytes was in the normal range expressing the RT6.1 differentiation antigen. Islets were heavily infiltrated with B and T lymphocytes, macrophages and NK cells with beta cells rapidly destroyed through apoptosis in areas of insulitis. This Type I diabetic rat develops a spontaneous insulin-dependent autoimmune diabetes through beta cell apoptosis. It could prove to be a valuable new animal model for clarifying the mechanisms involved in the development of autoimmune diabetes.

  11. Is pancreas development abnormal in the non-obese diabetic mouse, a spontaneous model of type I diabetes?

    F. Homo-Delarche

    2001-04-01

    Full Text Available Despite extensive genetic and immunological research, the complex etiology and pathogenesis of type I diabetes remains unresolved. During the last few years, our attention has been focused on factors such as abnormalities of islet function and/or microenvironment, that could interact with immune partners in the spontaneous model of the disease, the non-obese diabetic (NOD mouse. Intriguingly, the first anomalies that we noted in NOD mice, compared to control strains, are already present at birth and consist of 1 higher numbers of paradoxically hyperactive ß cells, assessed by in situ preproinsulin II expression; 2 high percentages of immature islets, representing islet neogenesis related to neonatal ß-cell hyperactivity and suggestive of in utero ß-cell stimulation; 3 elevated levels of some types of antigen-presenting cells and FasL+ cells, and 4 abnormalities of extracellular matrix (ECM protein expression. However, the colocalization in all control mouse strains studied of fibroblast-like cells (anti-TR-7 labeling, some ECM proteins (particularly, fibronectin and collagen I, antigen-presenting cells and a few FasL+ cells at the periphery of islets undergoing neogenesis suggests that remodeling phenomena that normally take place during postnatal pancreas development could be disturbed in NOD mice. These data show that from birth onwards there is an intricate relationship between endocrine and immune events in the NOD mouse. They also suggest that tissue-specific autoimmune reactions could arise from developmental phenomena taking place during fetal life in which ECM-immune cell interaction(s may play a key role.

    We measured the effects of fish protein (FP) on blood pressure, glycemia and antioxidant status in spontaneously hypertensive (SH) rats with streptozotocin-induced diabetes (STZ). Two groups of 12 rats each were fed 20% casein (C) or FP for 2 months. The total antioxidant status of blood and organs (liver, kidney and heart) was measured by the KRL test. Antioxidant enzyme activities (G-Px, G-Red, and SOD) and antioxidant substances (GSH, NO) were determined in organs, and vitamin C in plasma. FP lowered blood pressure in SH rats, but not in SH-STZ. Blood and plasma antioxidant status increased 35% and 9%, respectively, with FP in SH-STZ compared to SH rats; when compared to C, these values were more enhanced. SOD activity values were elevated with FP in SH-STZ rats, compared to the C diet, regardless of organ. Higher kidney NO and heart GSH values were noted in SH-STZ rats than SH. In SH rats fed FP, the GSH value was 2.26 times higher in liver, and NO was 3 times higher in heart. Higher NO was noted in kidney (1.84 times) and heart (1.91 times), GSH in heart (1.79 times), and vitamin C in plasma (+46%) in SH-STZ rats with FP than with C. Fish protein has a beneficial effect on blood pressure in SH rats but not in SH-STZ, and plays an important role in antioxidative defense. This protein may be useful in future treatments of such diseases as diabetes and hypertension.

    A specific RIA for somatostatin (SRIF) was used to determine the SRIF content of the pancreas and hypothalamus in spontaneously diabetic C57BL/KsJ dbdb and C57BL/6J obob mice. In addition, SRIF- and glucagon-containing cells were examined in the pancreatic islets with an immunohistochemical technique. In dbdb mice, immunoassayable pancreatic SRIF content was increased, as was the number of SRIF- or glucagon-containing cells. In obob mice, immunoassayable pancreatic SRIF content was also increased, but no increase was noted in the number of SRIF- or glucagon-containing cells. The hypothalamic SRIF content of either strain was not different from that of controls. These results regarding pancreatic SRIF content were in accord with some but not all previous reports. These differences may be related to the age of the mice or to the conditions in which they were bred. The pancreatic SRIF increase in both dbdb and obob mice may be attributable to hyperglucagonemia, hyperglycemia, or a decrease in insulin action. Further work is necessary to clearly delineate the mechanism

    Cerebral autoregulation is an important mechanism that involves dilatation and constriction in arterioles to maintain relatively stable cerebral blood flow in response to changes of systemic blood pressure. Traditional assessments of autoregulation focus on the changes of cerebral blood flow velocity in response to large blood pressure fluctuations induced by interventions. This approach is not feasible for patients with impaired autoregulation or cardiovascular regulation. Here we propose a newly developed technique-the multimodal pressure-flow (MMPF) analysis, which assesses autoregulation by quantifying nonlinear phase interactions between spontaneous oscillations in blood pressure and flow velocity during resting conditions. We show that cerebral autoregulation in healthy subjects can be characterized by specific phase shifts between spontaneous blood pressure and flow velocity oscillations, and the phase shifts are significantly reduced in diabetic subjects. Smaller phase shifts between oscillations in the two variables indicate more passive dependence of blood flow velocity on blood pressure, thus suggesting impaired cerebral autoregulation. Moreover, the reduction of the phase shifts in diabetes is observed not only in previously-recognized effective region of cerebral autoregulation (type 2 diabetes mellitus alters cerebral blood flow regulation over a wide frequency range and that this alteration can be reliably assessed from spontaneous oscillations in blood pressure and blood flow velocity during resting conditions. We also show that the MMPF method has better performance than traditional approaches based on Fourier transform, and is more suitable for the quantification of nonlinear phase interactions between nonstationary biological signals such as blood pressure and blood flow.

    Infant macrosomia is a classic feature of a gestational diabetes mellitus (GDM) pregnancy and is associated with increased risk of adult obesity and type II diabetes mellitus, however mechanisms linking GDM and later disease remain poorly understood. The heterozygous leptin receptor-deficient (Lepr(db/+)) mouse develops spontaneous GDM and the fetuses display characteristics similar to infants of GDM mothers. We examined the effects of GDM on maternal insulin resistance, fetal growth, and postnatal development of hepatic insulin resistance. Fetal body weight on d 18 of gestation was 6.5% greater (p obesity and insulin resistance in the livers of the adult offspring. The specific decrease in Akt phosphorylation in livers of adult offspring suggests that this may be a mechanism for reduced insulin-dependent physiologic events, such as suppression of hepatic glucose production, a defect associated with susceptibility to type II diabetes mellitus.

    Full Text Available Diabetes mellitus (DM is a chronic metabolic disorder in which blood glucose level raises that can result in severe complications. However, the incidence increased mostly by obesity, pregnancy, persistent corpus luteum, and diestrus phase in humans and animals. This review has focused on addressing the possible understanding and pathogenesis of spontaneous DM in canine, feline, and few wild animals. Furthermore, pancreatic associated disorders, diabetic ketoacidosis, hormonal and drug interaction with diabetes, and herbal remedies associated with DM are elucidated. Bibliographic search for the present review was done using PubMed, Scopus, and Google Scholar for articles on concurrent DM in small and wild animals. Persistent corpus luteal and pseudopregnancy in female dogs generate gestational DM (GDM. GDM can also be caused by extensive use of drugs/hormones such as glucocorticosteroids. Although many similarities are present between diabetic cats and diabetic humans which present islet amyloidosis, there was a progressive loss of β- and α-cells and the normal number of δ-cells. The most prominent similarity is the occurrence of islet amyloidosis in all cases of diabetic cat and over 90% of human non-insulin dependent DM Type-2. Acute pancreatic necrosis (APN occurs due to predisposing factors such as insulin antagonism, insulin resistance, alteration in glucose tolerance, obesity, hyperadrenocorticism, and persistent usage of glucocorticoids, as these play a vital role in the progression of APN. To manage such conditions, it is important to deal with the etiological agent, risk factors, diagnosis of diabetes, and hormonal and drug interaction along with its termination with suitable therapy (herbal protocols. It should be noted that the protocols used for the diagnosis and treatment of human DM are not appropriate for animals. Further investigations regarding diabetic conditions of pets and wild animals are required, which will benefit the

    Different regimens of food restriction have been associated with protection against obesity, diabetes and CVD. In the present study, we hypothesised that food restriction would bring benefits to atherosclerosis- and diabetes-prone hypercholesterolaemic LDL-receptor knockout mice. For this purpose, 2-month-old mice were submitted to an intermittent fasting (IF) regimen (fasting every other day) over a 3-month period, which resulted in an overall 20 % reduction in food intake. Contrary to our expectation, epididymal and carcass fat depots and adipocyte size were significantly enlarged by 15, 72 and 68 %, respectively, in the IF mice compared with the ad libitum-fed mice. Accordingly, plasma levels of leptin were 50 % higher in the IF mice than in the ad libitum-fed mice. In addition, the IF mice showed increased plasma levels of total cholesterol (37 %), VLDL-cholesterol (195 %) and LDL-cholesterol (50 %). As expected, in wild-type mice, the IF regimen decreased plasma cholesterol levels and epididymal fat mass. Glucose homeostasis was also disturbed by the IF regimen in LDL-receptor knockout mice. Elevated levels of glycaemia (40 %), insulinaemia (50 %), glucose intolerance and insulin resistance were observed in the IF mice. Systemic inflammatory markers, TNF-α and C-reactive protein, were significantly increased and spontaneous atherosclerosis development were markedly increased (3-fold) in the IF mice. In conclusion, the IF regimen induced obesity and diabetes and worsened the development of spontaneous atherosclerosis in LDL-receptor knockout mice. Although being efficient in a wild-type background, this type of food restriction is not beneficial in the context of genetic hypercholesterolaemia.

    Full Text Available Diabetes mellitus is a metabolic abnormality in which there is a failure to utilise glucose and hence a state of hyperglycaemia can occur. If hyperglycaemia continues uncontrolled over time, it will lead to significant and widespread pathological changes, including involvement of the retina, brain and kidney.In industrialised countries, approximately 1% of the population is diabetic, and at least another 1% are undiagnosed diabetics. Insulin dependent diabetes (IDDM, accounts for approximately 10-15% of cases, the remainder being maturity onset or non-insulin dependent diabetics (NIDDM. Diabetes mellitus is an international public health problem with estimated prevalences ranging from 2.0% to 11.7% in studied populations across the world.

    Diabetes is a chronic disease characterized by the body's inability to process blood glucose properly. It is generally classified as insulin-dependent diabetes mellitus (IDDM), or type 1, and non-insulin-dependent diabetes mellitus (NIDDM), or type 2. Type 1 is characterized by a defect in insulin secretion by the beta cells of the pancreas, usually secondary to autoimmune destruction of those cells. Type 2 is characterized by peripheral insulin resistance with an insulin-secretory defect that varies in severity. Diabetes is a common medical condition that affects 6% of Americans younger than 50 years and approximately 10% to 15% of those older than 50 years. Increasing numbers of patients who have diabetes are presenting to the oral surgeon's office for care. Patients who have diabetes have a 50% chance of undergoing a surgical procedure in their lifetime.

    1998-06-01

    Recently corneal autofluorescence has been proposed as an ocular diagnostic tool for diabetic retinopathy. The method is based on the sensible increase of the natural fluorescence of corneal tissue within specific wavelength in presence of early stage of diabetic retinopathy. The main advantages of this method are that the corneal autofluorescence has been demonstrated to be not age-related and that the cornea is readily accessible to be investigated. In this study 47 insulin-dependent diabetes mellitus and 51 non-insulin- dependent diabetes mellitus patients aged 20 - 90 years have been considered. Patients were selected from the Eye Clinic of S. Raffaele Hospital. The modified Airlie House classification was used to grade the diabetic retinopathy. Corneal autofluorescence has been measured by using both a specifically designed instrument and the Fluorotron Master. Corneal autofluorescence mean value for each diabetic retinopathy measured by using both the instruments correlated with the retinopathy grade.

    Full Text Available “Boiogito” is a Kampo preparation which has been used since ancient times in patients with obesity of the “asthenic constitution” type, so-called “watery obesity”, and its effect has been recognized clinically. In this study, we investigated the anti-obesity effect of Boiogito in the TSOD (Tsumura Suzuki Obese Diabetes mouse, a model of spontaneous obese type II diabetes mellitus. Boiogito showed a significant anti-obesity effect in TSOD mice by suppressing body weight gain in a dosage-dependent manner. In addition, Boiogito showed significant ameliorative effects on features of metabolic syndrome such as hyperinsulinemia, fasting hyperglycemia and abnormal lipid metabolism. Regarding lipid accumulation in TSOD mice, Boiogito showed a significant suppressive effect on accumulation of subcutaneous fat, but the effect on the visceral fat accumulation that constitutes the basis of metabolic syndrome was weak, and the suppressive effect on insulin resistance was also weak. Furthermore, Boiogito did not alleviate the abnormal glucose tolerance, the hypertension or the peripheral neuropathy characteristically developed in the TSOD mice. In contrast, in the TSNO (Tsumura Suzuki Non-Obesity mice used as controls, Boiogito suppressed body weight gain and accumulation of subcutaneous and visceral fat. The above results suggested that Boiogito is effective as an anti-obesity drug against obesity of the “asthenic constitution” type in which subcutaneous fat accumulates, but cannot be expected to exert a preventive effect against various symptoms of metabolic syndrome that are based on visceral fat accumulation.

    Full Text Available Abstract Background Diabetes is associated with changes in myocardial stress-response pathways and is recognized as an independent risk factor for cardiac remodeling. Using spontaneously diabetic Goto Kakizaki rats as a model of type 2 DM we investigated whether post-translational modifications in the Akt - FOXO3a pathway, Sirt1 - p53 pathway and the mitogen activated protein kinase p38 regulator are involved in post-infarct cardiac remodeling Methods Experimental myocardial infarction (MI was induced by left anterior descending coronary artery ligation in spontaneously diabetic Goto-Kakizaki rats and non-diabetic Wistar controls. Cardiac function was studied by echocardiography. Myocardial hypertrophy, cardiomyocyte apoptosis and cardiac fibrosis were determined histologically 12 weeks post MI or Sham operation. Western blotting was used to study Caspase-3, Bax, Sirt1, acetylation of p53 and phosphorylation of p38, Akt and FOXO3a. Electrophoretic mobility shift assay was used to assess FOXO3a activity and its nuclear localization. Results Post-infarct heart failure in diabetic GK rats was associated with pronounced cardiomyocyte hypertrophy, increased interstitial fibrosis and sustained cardiomyocyte apoptosis as compared with their non-diabetic Wistar controls. In the GK rat myocardium, Akt- and FOXO3a-phosphorylation was decreased and nuclear localization of FOXO3a was increased concomitantly with increased PTEN protein expression. Furthermore, increased Sirt1 protein expression was associated with decreased p53 acetylation, and phosphorylation of p38 was increased in diabetic rats with MI. Conclusions Post-infarct heart failure in diabetic GK rats was associated with more pronounced cardiac hypertrophy, interstitial fibrosis and sustained cardiomyocyte apoptosis as compared to their non-diabetic controls. The present study suggests important roles for Akt-FOXO3a, Sirt1 - p53 and p38 MAPK in the regulation of post-infarct cardiac remodeling

    Oxidative stress is implicated in the pathogenesis and/or complications of hypertension and/or diabetes mellitus. A combination of these disorders increases the risk of developing cardiovascular events. This study investigated the effects of streptozotocin (60 mg/kg; ip)-induced diabetes on blood pressure, oxidative stress and effects of honey on these parameters in the kidneys of streptozotocin-induced diabetic Wistar-Kyoto (WKY) and spontaneously hypertensive rats (SHR). Diabetic WKY and SHR were randomized into four groups and received distilled water (0.5 mL) and honey (1.0 g/kg) orally once daily for three weeks. Control SHR had reduced malondialdehyde (MDA) and increased systolic blood pressure (SBP), catalase (CAT) activity, and total antioxidant status (TAS). SBP, activities of glutathione peroxidase (GPx) and glutathione reductase (GR) were elevated while TAS was reduced in diabetic WKY. In contrast, SBP, TAS, activities of GPx and GR were reduced in diabetic SHR. Antioxidant (honey) treatment further reduced SBP in diabetic SHR but not in diabetic WKY. It also increased TAS, GSH, reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio, activities of GPx and GR in diabetic SHR. These data suggest that differences in types, severity, and complications of diseases as well as strains may influence responses to blood pressure and oxidative stress. PMID:21673929

    Type 1 diabetes mellitus (T1D) is caused by the destruction of insulin-producing β cells in pancreatic islets by autoimmune T cells. Islet transplantation has been established as an effective therapeutic strategy for T1D. However, the survival of islet grafts can be disrupted by recurrent autoimmunity. Dimethyl sulfoxide (DMSO) is a solvent for organic and inorganic substances and an organ-conserving agent used in solid organ transplantations. DMSO also exerts anti-inflammatory, reactive oxygen species scavenger and immunomodulatory effects and therefore exhibits therapeutic potential for the treatment of several human inflammatory diseases. In this study, we investigated the therapeutic potential of DMSO in the inhibition of autoimmunity. We treated an animal model of islet transplantation (NOD mice) with DMSO. The survival of the syngeneic islet grafts was significantly prolonged. The population numbers of CD8, DC and Th1 cells were decreased, and regulatory T (Treg) cell numbers were increased in recipients. The expression levels of IFN-γ and proliferation of T cells were also reduced following DMSO treatment. Furthermore, the differentiation of Treg cells from naive CD4 T cells was significantly increased in the in vitro study. Our results demonstrate for the first time that in vivo DMSO treatment suppresses spontaneous diabetes and autoimmune recurrence in NOD mice by inhibiting the Th1 immune response and inducing the differentiation of Treg cells. - Highlights: • We report a therapeutic potential of DMSO in autoimmune diabetes. • DMSO exhibits an immune modulatory effect. • DMSO treatment increases regulatory T cell differentiation. • The increase in STAT5 signaling pathway explains the effect of DMSO in Tregs.

  13. Acute phase serum proteins in diabetic retinopathy

    Directory of Open Access Journals (Sweden)

    Rema M

    1996-01-01

    Full Text Available The serum concentration of various acute phase reactants were studied in patients with non-insulin dependent diabetes mellitus with and without retinopathy and in control subjects. The serum levels of haptoglobin was elevated in diabetics with retinopathy and the levels were highest in those with proliferative diabetic retinopathy. The levels of serum albumin, alpha-1 acid glycoprotein, alpha-1 antitrypsin and caeruloplasmin were not significantly different between the patients with retinopathy and controls. Haptoglobin increases serum viscosity and this could be the mechanism by which it plays a role in pathogenesis of diabetic retinopathy. These preliminary observations need to be confirmed by studies based on larger number of patients. Longitudinal studies on acute phase reactants in various stages of development of diabetic retinopathy would also provide valuable information.

    Nonalcoholic steatohepatitis (NASH) is a progressive liver disease, and some patients develop hepatic cirrhosis/carcinoma. Animal models play key roles in the development of new therapies for NASH. In this study, the pharmacological effects of metformin and pioglitazone were investigated in female Spontaneously Diabetic Torii (SDT) fatty rats to verify the utility of this model. The anti-diabetic drugs were administered to SDT fatty rats fed a cholesterol-enriched diet from 4 to 25 weeks, and changes in food intake, body weight, and blood chemistry parameters were evaluated every 4 weeks. The hepatic lipid content, mRNA expression in relation to lipid synthesis, inflammation, and fibrosis, and histopathological analyses were performed at 25 weeks. Pioglitazone improved hyperglycemia, hyperlipidemia, and abnormalities in hepatic parameters. The insulin levels were lower than those in the control rats before 16 weeks. Plasma glucose levels in the metformin-treated rats were lower than those in the control rats, and plasma triglyceride and alanine aminotransferase levels temporarily decreased. The lipid content and some mRNA expression in relation to fibrosis in the liver decreased with pioglitazone treatment, and the mRNA expression of microsomal triglyceride transfer protein increased. Hepatic fibrosis observed in the SDT fatty rats improved with pioglitazone treatment; however, the effect with metformin treatment was partial. These results in both drugs are in line with results in the human study, suggesting that the SDT fatty rat is useful for developing new anti-NASH drugs that show potential to regulate glucose/lipid metabolism.

It is found that levels of serum and urine β 2 -MG in diabetes are significantly higher than that of normal contrasts (P 2 -MG are increased with diabetes progress, especially urine β 2 -MG. There is no difference in levels of serum and urine β 2 -MG between non-insulin dependent diabetes mellitus (NIDDM) and insulin dependent diabetes mellitus (IDDM, P>0.05). Urine β 2 -MG levels of diabetes are relatively increased with the increase of serum β 2 -MG levels. Both are obviously positive correlation. While diabetes progressing, both are gradually increased. It can be shown that the longer diabetes process, the more renal function was damaged. Therefore, determination of β 2 -MG is very important for early diagnosing, preventing and treating diabetic nephropathy

    Full Text Available The role of oxidant stress in the causation of chronic tissue damage is being increasingly recognized. Oxidant stress is usually countered by abundant supply of antioxidants. If concomitant antioxidant deficiency occurs, oxidant stress may produce tissue damage. We took up a study on antioxidant status in non-insulin dependent diabetes mellitus (NIDDM patients with and without retinopathy and compared them with a control non-diabetic group. The levels of superoxide dismutase (SOD were significantly reduced in all diabetic patients, i.e., those with and without retinopathy. However, the lowest levels were found in the diabetic patients with retinopathy. Vitamin E and vitamin C levels were also markedly lower in the diabetic patients. There was a paradoxical rise in the catalase and glutathione peroxidase (GPx in the diabetic patients with retinopathy. This may be a compensatory mechanism by the body to prevent tissue damage by increasing the levels of the two alternative antioxidant enzymes.

    Full Text Available Background: Diabetic neuropathy is an incapacitating disease that afflicts almost 50 percent of patients with diabetes. A late finding in type 1 diabetes, diabetic neuropathy can be an early finding in non insulin-dependent diabetes. Diabetic neuropathies are divided primarily into two groups, sensorimotor and autonomic. Patients may acquire only one type of diabetic neuropathy or may present with combinations of neuropathies, such as autonomic neuropathy or distal symmetric polyneuropathy, the latter of which the most common form. Motor deficits, orthostatic hypotension, silent cardiac ischemia, hyperhidrosis, vasomotor instability, gastroparesis, bladder dysfunction, and sexual dysfunction can also result from diabetic neuropathy. Strict control of blood sugar, combined with proper daily foot care, is essential to avoid the complications of this disorder. With the potential to afflict any part of the nervous system, diabetic neuropathy should be suspected in all patients with type 2 diabetes as well as patients who have had type 1 diabetes for over five years. Although some patients with diabetic neuropathy notice few symptoms, upon physical examination mild to moderately severe sensory loss may be noted by the physician. Idiopathic neuropathy has been known to precede the onset of type 2 diabetes.

    Several crossing studies using diabetic BB/OK and diabetes-resistant rat strains have clearly shown that the MHC class-II-genes of the RT1u haplotype (Iddm1) and the lymphopenia (Iddm2) are essential but not sufficient for type 1 diabetes development. The search for additional diabetogenic genes revealed predisposing non-MHC genes, Iddm3 and Iddm4, and a diabetes protective gene, Iddm5r, cosegregating with diabetes in the BB/OK rat subline. These findings were based on cosegregation studies comparing allele frequencies between diabetic and non-diabetic cross hybrids. Since, type 1 diabetes is characterised by hyperglycaemia we analysed 22 diabetic and 43 non-diabetic [(BB x SHR)FI x BB] backcross hybrids (28M:37F) which were already homozygous for Iddml and Iddm2 to search for quantitative trait loci (QTLs) affecting blood glucose in BB/OK rats. The QTL analysis using 117 microsatellite markers located on 19 autosomal chromosomes and the X chromosome, revealed suggestive linkage for blood glucose at the same position for diabetics (lod score 3.1) and non-diabetics at an age of 16 weeks at locus D6Mgh2 on chromosome 6 (lod score 1.9). In contrast, the peak for nondiabetics at an age of 28 weeks (lod score 3.1) was located in the region on chromosome 1 flanked by D1Mgh12 and D1Mit14, whereas the peak for diabetics (lod score 1.9) was found between Sa and Igf2. The distance between two peaks is ca. 50 cM. These findings are consistent with previously described results and provide strong evidence on the relevance of the described region for the development of diabetes not only in the rat, but, regarding the chromosomal homology also in human.

    Diabetes mellitus is a metabolic disease with systemic manifestations. Occurrence is increasing worldwide from 153m to 347m from 1980 to 2011. Traditionally there are two main types: Insulin dependent or juvenile diabetes and non-insulin dependent or Maturity onset or insulin resistant diabetes. Gestational diabetes the second type of diabetes is increasingly seen in young patients and it evolves into insulin dependence. Obesity is causally related to type II diabetes. Diabetes Mellitus affects appendicular and peripheral structures more commonly – ankle and feet. Diabetes in the MSK System effects manifested as congenital problems, Peripheral neuropathy, Peripheral vasculopathy Infections and Connective tissue changes. The disease target Structures like Cardio-vascular system, Central nervous system (brain, eyes) and peripheral nerves, Reticulo-endothelial system, Kidneys and Musculoskeletal system. Osteomyelitis fractures including fragmentation of bones and disorganization of joints – neuropathic changes. Diabetic Myopathy occurs predominantly in long-standing, poorly controlled type 1 diabetics often have other vascular or end organ complications. Etiology related to microvascular disease leads to muscle ischemia and infarction eventual muscle atrophy

    Metabolic syndrome is one of the most important health issues worldwide. Obesity causes insulin resistance, hyperlipidemia, diabetes, and various diseases throughout the body. The liver phenotype, which is called nonalcoholic steatohepatitis (NASH), frequently progresses to hepatocellular carcinoma. We recently established a new animal model, Tsumura-Suzuki obese diabetic (TSOD) mice, which spontaneously exhibit obesity, diabetes, hyperlipidemia, and NASH with liver nodules. We examined the effects of coffee intake on various conditions of the metabolic syndrome using TSOD mice. The daily volume of coffee administered was limited so that it reflected the appropriate quantities consumed in humans. To clarify the effects of the specific components, animals were divided into two coffee-intake groups that included with and without caffeine. Coffee intake did not significantly affect obesity and hyperlipidemia in TSOD mice. In contrast, coffee intake caused various degrees of improvement in the pancreatic beta cell damage and steatohepatitis with liver carcinogenesis. Most of the effects were believed to be caused by a synergistic effect of caffeine with other components such as polyphenols. However, the antifibrotic effects of coffee appeared to be due to the polyphenols rather than the caffeine. A daily habit of drinking coffee could possibly play a role in the prevention of metabolic syndrome.

    Full Text Available BACKGROUND Diabetic neuropathy, retinopathy and nephropathy are the chronic complications of diabetes mellitus. Neuropathy, retinopathy and nephropathy are microvascular complication of diabetes mellitus. Antioxidant status is reduced in DM-induced retinopathy and nephropathy. Present study is undertaken to evaluate the degree of oxidative stress in diabetic neuropathy patients. The aim of the study is to study on oxidative stress as measured by lipid peroxidation marker, malondialdehyde and antienzyme status in type II DM patients with neuropathy and compared them with a controlled nondiabetic group. MATERIALS AND METHODS The study included 100 subjects from Sapthagiri Medical College, Bangalore, from January 1, 2015, to December 31, 2015, of age group 50 to 70 yrs. out of which 50 patients were non-insulin-dependent DM with neuropathy and rest 50 age and sex matched apparently healthy individuals (control group. Antioxidant status was assessed by measuring superoxide dismutase (SOD, glutathione peroxidase (GPx, glutathione reductase (GR, Catalase and Reduced Glutathione (GSH. RESULTS It showed a significant increase p<0.001 in FBS, PPBS, TC, TG, LDL, VLDL, CAT, MDA, while HDL, GSH, GPX, GR and SOD were found to be decreased significantly (p 0.001. CONCLUSION MDA was significantly elevated in diabetic group, whereas antioxidant enzymes superoxide dismutase, glutathione peroxidase, glutathione reductase and reduced glutathione were significantly decreased, which might be helpful in risk assessment of various complications of DM. The data suggests that alteration in antioxidant status and MDA may help to predict the risk of diabetic neuropathy.

    Coronary artery and peripheral occlusive arterial disease frequently complicate diabetes mellitus, with death due to atherosclerotic coronary artery disease being three times more likely in diabetic compared to non-diabetic patients. The profile of 32 diabetic patients and 32 matched controls who underwent coronary artery bypass (CABG) is studied and their early and late postoperative outcomes are described. The mean age was 61 +\\/- 1 year in both groups. The diabetic group comprised 26 non-insulin dependent and 6 insulin dependent diabetics, who had a mean duration of diabetes of 8.5 years (range 2 months--35 years). The median number of grafts per patient performed in the diabetic group and the control group was 3.5 and 3 respectively. There was no mortality in the series, however considerably greater wound morbidity rates were encountered in the diabetic group when compared to matched controls. One renal transplant patient in the diabetic group suffered irreversible acute tubular necrosis and became dialysis dependent post-operatively. Longterm follow-up showed no longterm mortality in either group, with full relief of angina achieved in 75% of diabetic patients compared with 87.5% of matched controls. In addition diabetic patients suffered greater longterm cardiac morbidity than the control group (21.8% versus 12.5%). The results of this study suggest that CABG is a safe operation for the diabetic patient. Diabetic patients receive satisfactory symptomatic relief of angina, but suffer increased perioperative wound complications and greater incidence of longterm cardiac morbidity.

    Elevated arginase (Arg) activity is reported to be involved in diabetes-induced vascular endothelial dysfunction. It can reduce L-arginine availability to nitric oxide (NO) synthase (NOS) and NO production. Akita mice, a genetic non-obese type 1 diabetes model, recapitulate human diabetes. We determined the role of Arg in a time-course of diabetes-associated endothelial dysfunction in aorta and corpora cavernosa (CC) from Akita mice. Endothelium-dependent relaxation, Arg and NOS activity, and protein expression levels of Arg and constitutive NOS were assessed in aortas and CC from Akita and non-diabetic wild type (WT) mice at 4, 12 and 24 wks of age. Systolic blood pressure (SBP) was assessed by tail cuff. In aorta and CC, Akita mice exhibited a progressive impairment of vascular endothelial and nitrergic function increased Arg activity and expression (Arg1 in aorta and both Arg1 and Arg2 in CC) compared with that of age-matched WT mice. Treatment of aorta and CC from Akita mice with an Arg inhibitor (BEC or ABH) reduced diabetes-induced elevation of Arg activity and restored endothelial and nitrergic function. Reduced levels of phospho-eNOS at Ser(1177) (in aorta and CC) and nNOS expression (in CC) were observed in Akita mice at 12 and 24 wks. Akita mice also had decreased NOS activity in aorta and CC at 12 and 24 wks that was restored by BEC treatment. Further, Akita mice exhibited moderately increased SBP at 24 wks and increased sensitivity to PE-induced contractions in aorta and sympathetic nerve stimulation in CC at 12 and 24 wks. Over 24 wks of diabetes in Akita mice, both aortic and cavernosal tissues exhibited increased Arg activity/expression, contributing to impaired endothelial and nitrergic function and reduced NO production. Our findings demonstrate involvement of Arg activity in diabetes-induced impairment of vascular function in Akita mouse.

    Diabetes mellitus alters the vascular responsiveness to several vasoconstrictors and vasodilators. 5-amino-4-imidazole-carboxamide riboside (AICA-r), a nucleoside corresponding to AICA-ribotide and an intermediate of the de novo pathway of purine biosynthesis, was recently proposed as a new insulinotropic tool in non-insulin-dependent diabetes mellitus. The aim of the present study was to define whether AICA-r affects altered vascular responsiveness to vasoconstrictors and vasodilators in the thoracic aorta of neonatal streptozotocin (STZ)-diabetic rats. The results of this study indicate that a 1-month treatment with AICA-r significantly increases the body weight in diabetic rats; significantly decreases the blood glucose level of diabetic rats (from 302+/-47 to 135+/-11 mg/dL, pAICA-r treatment in neonatal STZ-diabetic rats improved increased blood glucose levels, accelerated weight gain, reversed endothelial dysfunction, and normalized vascular responses.

    Diabetes mellitus is a complex metabolic disorder associated with an increased risk of microvascular and macrovascular disease; its main clinical characteristic is hyperglycaemia. The last century has been characterised by remarkable advances in our understanding of the mechanisms leading to hyperglycaemia. The central role of insulin in glucose metabolism regulation was clearly demonstrated during the early 1920s, when Banting, Best, Collip and Macleod successfully reduced blood glucose levels and glycosuria in a patient treated with a substance purified from bovine pancreata. Later, during the mid-1930s, clinical observations suggested a possible distinction between 'insulin-sensitive' and 'insulin-insensitive' diabetes. Only during the 1950s, when a reliable measure of circulating insulin was available, was it possible to translate these clinical observations into pathophysiological and biochemical differences, and the terms 'insulin-dependent' (indicating undetectable insulin levels) and 'non-insulin-dependent' (normal or high insulin levels) started to emerge. The next 30 years were characterised by pivotal progress in the field of immunology that were instrumental in demonstrating an immune-mediated loss of insulin-secreting β-cells in subjects with 'insulin-dependent' diabetes. At the same time, new experimental techniques allowing measurement of insulin 'impedance' showed a reduced peripheral effect of insulin in subjects with 'non-insulin-dependent' diabetes (insulin resistance). The difference between the two types of diabetes emerging from decades of observations and experiments was further formally recognised in 1979, when the definitions 'type I' and 'type II' diabetes were introduced to replace the former 'insulin-dependent' and 'non-insulin-dependent' terms. In the following years, many studies elucidated the natural history and temporal contribution of insulin resistance and β-cell insulin secretion in 'type II' diabetes. Furthermore, a central

    The co-ordinated induction of several hepatic drug-metabolizing enzymes is a common feature in the regulation of drug biotransformation under normal and pathological conditions. In the present study the activity and expression of bilirubin UDP-glucuronosyltransferase (UGT1A1) were investigated in livers of BioBreeding/Worcester diabetic, fasted and acetone-treated rats. Bilirubin glucuronidation was stimulated by all three treatments; this was correlated with an increase in the UGT1A1 protein concentration in hepatic microsomes. Transcriptional induction of UGT1A1 was also observed in diabetes and starvation but not with acetone treatment, which apparently caused translational stabilization of the enzyme protein. The hormonal/metabolic alterations in diabetes and starvation might be a model for postnatal development. The sudden interruption of maternal glucose supply signals the enhanced expression of UGT1A1, giving a novel explanation for the physiological induction of bilirubin glucuronidation in newborn infants.

    As baby boomers age and their expected life span increases, there is an unprecedented need to better manage the health care of elders with diabetes who are at increased risk of falling due to diabetes complications, frailty, or other conditions. New clinical and research tools are needed to measure functioning accurately and to identify early indicators of risk of falling, thus translating into more effective and earlier intervention. The objective of this pilot study was to validate a significant change in hardware and algorithm to track activity patterns using a single triaxial accelerometer through validation of timed up and go and standard measures of balance and gait. We recruited a convenience sample of eight older adults with diabetes and peripheral neuropathy (age, 77 ± 7 years old) who were asked to wear the sensor for imposed daytime activity performed in our gait laboratory. Subjects were stratified into risk of falling categories based on Tinetti scores. We examined the accuracy of the suggested technology for discrimination of high- versus low-risk groups. The system was accurate in identifying the number of steps taken and walking duration (random error risk of falling, suggesting that subjects with high risk of falling required a substantially longer duration for rising from a chair when compared with those with low risk of falling (p risk of falling, and could be useful for intermittent or even continuous monitoring of older adults with diabetes. Other potential applications could include activity monitoring of the diabetes population with lower extremity disease and of patients undergoing surgical procedures or as an objective measure during rehabilitation. © 2013 Diabetes Technology Society.

    The prevalence of rotator cuff tears increases with age and several studies have shown that diabetes is associated with symptomatic shoulder pathologies. Aim of our research was to evaluate the prevalence of shoulder lesions in a population of asymptomatic elderly subjects, normal and with non insulin - dependent diabetes mellitus. The study was performed on 48 subjects with diabetes and 32 controls (mean age: 71.5 ± 4.8 and 70.7 ± 4.5, respectively), who did not complain shoulder pain or dysfunction. An ultrasound examination was performed on both shoulders according to a standard protocol, utilizing multiplanar scans. Tendons thickness was greater in diabetics than in controls (Supraspinatus Tendon: 6.2 ± 0.09 mm vs 5.2 ± 0.7 mm, p shoulder symptomatic pathologies.

METHODS: Transversal study of diabetic patients without previous ophthalmologic treatment, seen at a University eye clinic. These patients underwent fundus photography, complete blood work-up, systemic blood pressure measurement, urine analysis, and were questioned about risk factors previously determined by the authors. The presence or absence of risk factors was compared to the severity of diabetic retinopathy. RESULTS: Eighty-one patients were selected, 28 male, 53 female, 55 Caucasians, 26 African descendants, 28 had insulin-dependent diabetes mellitus, 53 had non-insulin-dependent diabetes mellitus. Factors related to more severe diabetic retinopathy include: insulin-dependent diabetes mellitus (a<0.01, nephropathy (a<0.05, proteinuria (a<0.05, duration of the disease (p<0.001, elevated fasting plasma glucose (p=0.11, glycosylated hemoglobin (HbA (1c (p=0.001, total serum cholesterol (p=0.019, lower hematocrit (p=0.004 and hemoglobin (p=0.001. CONCLUSIONS: The severity of diabetic retinopathy appears to be associated with risk factors such as duration of disease, type of diabetes, poor metabolic control, hemoglobin levels, total cholesterol and proteinuria. Factors apparently not related to severity of diabetic retinopathy include gender, age, systemic hypertension and hypomagnesemia.

    Functional images of K complex (KC) and regional myocardial glucose utilization rates (rMGU), derived from F-18-fluoro-deoxy-glucose (F-18-FDG) positron emission computed tomography, were prepared. Using functional images obtained, myocardial glucose metabolism was examined in the fasting state, oral glucose loading (OG), and insulin clamp (IC) condition. The subjects were 10 patients with diabetes mellitus (DM), consisting of 8 with non-insulin dependent DM and 2 with insulin dependent DM, and 4 normal persons. Image quality, derived from both OG and IC approaches, was favorable in the normal group. In the groups of non-insulin dependent DM and insulin dependent DM patients, however, image quality was good with IC method but not with OG method. In the group of non-insulin dependent DM, rMGU derived by IC method was relatively high, but was significantly lower than that in the control group, suggesting a decreased function in glucose transporter. When using OG method, rMGU was even more decreased due to high blood sugar and low insulin. In the group of insulin dependent DM, both IC and OG approaches achieved the same rMGU as that in the control group, with the exception of KC derived by OG method that was decreased due to high blood sugar. In moderate or severe DM, myocardial viability seems to be difficult to evaluate because F-18-FDG uptake is decreased in the ischemic area associated with fasting high blood sugar. Mismatching between blood flow and metabolism is also difficult to detect due to high insulin or glucose load. Thus, myocardial viability should be evaluated in the condition of slightly loaded insulin by decreasing blood sugar. (N.K.)

    Type 2 diabetes is associated with altered regional blood flow and expression of nitric oxide synthase (NOS). We examined the functional role of constitutive and inducible NOS synthase (cNOS and iNOS, respectively) on regional blood flow in thiobutabarbital-anesthetized Zucker diabetic fatty (ZDF) and control rats via the radioactive microspheres technique. Blood flow was measured at baseline (1 h after surgery), after i.v. administration of 1400W (N-3-aminomethyl-benzyl-acetamidine, selective iNOS inhibitor, 3 mg/kg), and again after i.v. N(G)-nitro-l-arginine methyl ester (L-NAME, non-selective NOS inhibitor, 8 mg/kg). Both groups had similar baseline mean arterial pressure, cardiac output and total peripheral resistance, but the ZDF rats had lower heart rate relative to the control rats (272 versus 305 beats/min). Whereas 1400W did not alter mean arterial pressure or blood flow in either group, L-NAME markedly increased mean arterial pressure and total peripheral resistance, and reduced cardiac output, heart rate, blood flow and arterial conductance in all organs/tissues of both the control and ZDF rats. L-NAME caused greater vasoconstriction in the heart (1.5-times the constriction in control rats) and brain (1.5-times) of the ZDF rats, but less in the pancreas (0.6-times). Thus, cNOS had greater vasodilator control of the heart and brain, but less in the pancreas of the ZDF than control rats. iNOS has negligible influence on blood flow in both groups of rats.

    The ob/ob mouse is genetically deficient in leptin and exhibits a phenotype that includes obesity and non-insulin-dependent diabetes mellitus. This phenotype closely resembles the morbid obesity seen in humans. In this study, we demonstrate that a single intramuscular injection of a recombinant adeno-associated virus (AAV) vector encoding mouse leptin (rAAV-leptin) in ob/ob mice leads to prevention of obesity and diabetes. The treated animals show normalization of metabolic abnormalities including hyperglycemia, insulin resistance, impaired glucose tolerance, and lethargy. The effects of a single injection have lasted through the 6-month course of the study. At all time points measured the circulating levels of leptin in the serum were similar to age-matched control C57 mice. These results demonstrate that maintenance of normal levels of leptin (2-5 ng/ml) in the circulation can prevent both the onset of obesity and associated non-insulin-dependent diabetes. Thus a single injection of a rAAV vector expressing a therapeutic gene can lead to complete and long-term correction of a genetic disorder. Our study demonstrates the long-term correction of a disease caused by a genetic defect and proves the feasibility of using rAAV-based vectors for the treatment of chronic disorders like obesity.

    Human and animal studies strongly suggest that dietary gluten could play a causal role in the etiopathogenesis of type 1 diabetes (T1D). However, the mechanisms have not been elucidated. Recent reports indicate that the intestinal microbiome has a major influence on the incidence of T1D. Since diet is known to shape the composition of the intestinal microbiome, we investigated using non-obese diabetic (NOD) mice whether changes in the intestinal microbiome could be attributed to the pro- and anti-diabetogenic effects of gluten-containing and gluten-free diets, respectively. NOD mice were raised on gluten-containing chows (GCC) or gluten-free chows (GFC). The incidence of diabetes was determined by monitoring blood glucose levels biweekly using a glucometer. Intestinal microbiome composition was analyzed by sequencing 16S rRNA amplicons derived from fecal samples. First of all, GCC-fed NOD mice had the expected high incidence of hyperglycemia whereas NOD mice fed with a GFC had significantly reduced incidence of hyperglycemia. Secondly, when the fecal microbiomes were compared, Bifidobacterium, Tannerella, and Barnesiella species were increased (p = 0.03, 0.02, and 0.02, respectively) in the microbiome of GCC mice, where as Akkermansia species was increased (p = 0.02) in the intestinal microbiomes of NOD mice fed GFC. Thirdly, both of the gluten-free chows that were evaluated, either egg white based (EW-GFC) or casein based (C-GFC), significantly reduced the incidence of hyperglycemia. Interestingly, the gut microbiome from EW-GFC mice was similar to C-GFC mice. Finally, adding back gluten to the gluten-free diet reversed its anti-diabetogenic effect, reduced Akkermansia species and increased Bifidobacterium, Tannerella, and Barnesiella suggesting that the presence of gluten is directly responsible for the pro-diabetogenic effects of diets and it determines the gut microflora. Our novel study thus suggests that dietary gluten could modulate the incidence of

In this study are included the patients with diabetes mellitus type 1 insulin-dependent--DMID and diabetes mellitus type 2 non-insulin-dependent--DMNID. The duration of diabetes in the examined patients varied from 5 till 30 years. We have applied examination by ophthalmoscope, slit lamp bio-microscopy with Volk and Goldman lens, optical coherence tomography--OCT as well as fluorescein angiography--FAG. Have been included the treated patients with DR, from September 2004-2014. In diabetic patients suffering for a period of 5 years, the prevalence of DR is 10%. In diabetic patients suffering over 30 years, the prevalence of DR is varied from 82% until 97%. Diabetic retinopathy, undertakes a multidisciplinary approach in all patients with diabetes to achieve optimal blood glucose control HbA1c levels 7.0% or lower and to adequately manage systolic blood pressure less than 140 mmHg and serum LDL cholesterol of less than 2.5 mmol/L and triglycerides of less than 2.0 mmol/L. Always should be assessed visual acuity at the time of DR examination.

    In the present study, the effects of Euglena and paramylon on hyperglycemia were examined in Otsuka Long-Evans Tokushima fatty (OLETF; type 2 diabetes mellitus model) rats. OLETF rats were fed an AIN-93 M diet containing cellulose, Euglena, or paramylon for 10 weeks. Long-Evans Tokushima Otsuka (LETO) rats were used as nondiabetic controls. An oral glucose-tolerance test (OGTT) was performed at 0 and 10 weeks. OLETF control rats were obese because of bulimia and showed abdominal fat accumulation and hyperglycemia. Euglena supplementation improved hyperglycemia and decreased food intake, body weight gain, and abdominal fat. However, there were no changes in the paramylon-supplemented group compared to the OLETF control group. Triglyceride concentrations in the serum and liver were lower in Euglena-supplemented rats than in OLETF control rats. There was a correlation between hepatic triglyceride concentration and the area under the curve (AUC) of OGTT at 10 weeks. This suggests that the improvement in glycemic control in the Euglena-supplemented group may depend on substances other than paramylon present in Euglena.

    Full Text Available A case with bilateral spontaneous pneumothorax was presented. Etiology, mechanism, and treatment were discussed on the review of literature. Spontaneous Pneumothorax is a clinical entity resulting from a sudden non traumatic rupture of the lung. Biach reported in 1880 that 78% of 916 patients with spontaneous pneumothorax had tuberculosis. Kjergaard emphasized 1932 the primary importance of subpleural bleb disease. Currently the clinical spectrum of spontaneous pneumothorax seems to have entered a third era with the recognition of the interstitial lung disease and AIDS as a significant etiology. Standard treatment is including: observation, thoracocentesis, tube thoracostomy. Chemical pleurodesis, bullectomy or wedge resection of lung with pleural abrasion and occasionally pleurectomy. Little information has been reported regarding the efficacy of such treatment in spontaneous pneumothorax secondary to non bleb disease

    country and is becoming an increasingly alarming public health problem. In spite of advances in the treatment of diabetes and improved obstetric care, gestational diabetes puts a pregnant woman at high risk of spontaneous abortion, ketoacidosis, hypoglycemia, hypertension, and other serious disorders. This study used life histories to investigate the relationship between health, sexuality, and work in five working women who were diabetic and pregnant and who received care at the Prenatal Care Outpatient Clinic of the San Pablo Hospital. All these women had non-insulin-dependent diabetes mellitus, were between 26 and 43 years old, and earned from US$ 150 to 375 per month for working 8-hour days, with one day off each week. Two of the women's male partners were unemployed; all of the women performed household chores during their day off. Quotations taken directly from conversations with the five participants reveal: the difficulty of caring for children and working; the sexual harassment that some of them suffered; the conflict and dissatisfaction associated with work; the myth of the natural joy of motherhood; the sexual control exercised by males; the interference of working conditions and work activities with pregnancy; and the perception that they did not have legal protection owing to employers' lack of respect for workers' rights and for the maternity protection provisions of the Federal Constitution of Brazil. It is concluded that health policies should pay greater attention to improving the quality of life of working women, especially if they suffer from diabetes and are pregnant.

    Global and regional myocardial uptake was determined with technetium-99m tetrofosmin and a 4 hour exercise (370 MBq iv) and rest (740 MBq iv) protocol, in 24 patients with non-insulin dependent diabetes mellitus and in 22 control subjects. The purpose of this study was to evaluate impaired coronary microvascular function in diabetics by measurement of % uptake increase in myocardial counts. The parameter of % uptake increase (ΔMTU) was calculated as the ratio of exercise counts to rest myocardial counts with correction of myocardial uptake for dose administered and physical decay between the exercise study and the rest study. Global ΔMTU was significantly lower in the diabetics than in control subjects (14.4±5.4% vs. 21.7±8.5%, p<0.01). Regional ΔMTU in each of 4 left ventricular regions (anterior, septal, inferior, posterolateral) was significantly lower in the diabetic group than in the control group (p<0.01) respectively, but there were no significant differences between ΔMTU in the 4 left ventricular regions in the same group. ΔMTU was useful as a non-invasive means of evaluating impaired coronary microvascular function in diabetics. (author)

    The respective effects of 6 month's administration of beta-blockers (atenolol, metoprolol, carteolol and arotinolol), calcium-channel blockers (nicardipine, diltiazem) and angiotensin converting enzyme inhibitor (enalapril) on hemoglobin A1c (HbA1c) levels were evaluated in hypertensive patients with non-insulin-dependent diabetes mellitus (NIDDM), using a retrospective method. NIDDM patients with stable HbA1c and body weight were selected for this study. The following results were obtained. (1) The administration of nicardipine or beta-blockers significantly elevated HbA1c levels. (2) The administration of diltiazem or enalapril did not have any influence on HbA1c levels. These findings suggest that not only beta-blocker but nicardipine (dihydropyridine type calcium-channel blocker) may cause deterioration in glucose metabolism in NIDDM patients.

    Hispanics in the United States have a disproportionately high risk for non-insulin-dependent diabetes mellitus (type 2 diabetes) compared with non-Hispanic whites. Little is known of the attitudes and beliefs about diabetes in this group. Using data from six focus groups of 42 Mexican Americans (14 men and 28 women), we characterized perceptions about the causes of and treatments for type 2 diabetes. Many participants believed diabetes is caused by having a family history of the disease, eating a diet high in fat or sugar, and engaging in minimal exercise. Experiencing strong emotions such as fright (susto), intense anger (coraje), or sadness and depression (tristeza) was also thought to precipitate diabetes. Nearly all participants expressed the belief that it is important to follow doctors' recommendations for diet and exercise, oral medication or insulin; many also cited herbal therapies, such as prickly pear cactus (nopal) and aloe vera (savila) as effective treatments. These findings may be useful in designing interventions to reduce the burden of diabetes in Hispanic populations.

    Diabetes mellitus (DM) is a complex disease with alterations in metabolic and inflammatory markers. Stillman Salgado rats (eSS) spontaneously develop type 2 DM by middle age showing progressive impairment of glucose tolerance with hyperglycemia, hypertriglyceridemia and hyperinsulinemia. We analyzed the effects of supplementation of ω-3 and ω-6 polyunsaturated fatty acids (PUFAs) with or without nordihydroguaiaretic acid (NDGA) added, an antioxidant and lipoxygenase inhibitor, on metabolic and inflammatory parameters in eSS rats to evaluate whether they can delay development and/or prevent progression of DM. After weaning, eSS rats received, intraperitoneally, once a month ω-3 (EPA 35% and DHA 40%-6.25 mg/Kg) or ω-6 (90% arachidonic acid- 6. 25 mg/Kg) for twelve months. Two additional groups of rats received 1.9 mg/kg NDGA added to ω-3 and ω-6 fatty acids. Blood samples were collected at day 40, and at the end of the 6th month and 12th month of age to determine plasma triglycerides (TGs), total plasma fatty acids (FA), A1C hemoglobin (HbA1C), C-reactive protein (CRP), gamma glutamyl transpeptidase (GGT), lipo and hydro peroxides, nitrites and IL-6 (in plasma and liver, kidney, and pancreas) and underwent oral glucose tolerance test (OGTT) as well. Wistar and eSS rats that received saline solution were used as controls. Plasma lipids profile, TG, fasting and post-prandial blood glucose levels, and glycosylated HbA1C showed significant improvements in ω-3 and ω-3 + NDGA treated animals compared to eSS control group. ω-3 and ω-3 + NDGA groups showed an inverse correlation with fasting blood glucose and showed lower plasma levels of GGT, TG, and CRP. eSS rats treated with ω-3 LCPUFAs showed reduced level of inflammatory and oxidative indices in plasma and liver, kidney and pancreas tissues in comparison with eSS control (non-treated) and ω-6 treated groups. eSS rats are a useful model to study type 2 DM pathophysiology and related inflammatory

    Full Text Available Abstract Background The prevalence of Metabolic Syndrome and related chronic diseases, among them non-insulin-dependent (type 2 diabetes mellitus, are on the rise in the United States and throughout the world. Animal models that respond to environmental stressors, such as diet, are useful for investigating the outcome and development of these related diseases. Objective Within this context, growth and energy relationships were characterized in the Nile rat, an exotic African rodent, as a potential animal model for diet-induced type 2 diabetes mellitus and Metabolic Syndrome. Methods Compiled data from several studies established the relationship between age, body weight gain (including abdominal adiposity, food and water consumption, and blood glucose levels as determinants of diabetes in male and female Nile rats. Glucose Tolerance Testing, insulin, HbA1c, blood pressure measurements and plasma lipids further characterized the diabetes in relation to criteria of the Metabolic Syndrome, while diet modification with high-fat, low-fiber or food restriction attempted to modulate the disease. Results The Nile rat fed lab chow demonstrates signs of the Metabolic Syndrome that evolve into diet-induced non-insulin-dependent (type 2 diabetes mellitus characterized by hyperinsulinemia with rising blood glucose (insulin resistance, abdominal adiposity, and impaired glucose clearance that precedes increased food and water intake, as well as elevated HbA1c, marked elevation in plasma triglycerides and cholesterol, microalbuminuria, and hypertension. Males are more prone than females with rapid progression to diabetes depending on the challenge diet. In males diabetes segregated into early-onset and late-onset groups, the former related to more rapid growth and greater growth efficiency for the calories consumed. Interestingly, no correlation was found between blood glucose and body mass index (overall adiposity in older male Nile rats in long term studies

    Full Text Available Type II (non-insulin-dependent diabetes is one of the most widespread chronic patologies in the developed countries and its prevalence in Italy is about 2-3% of the population. Type II diabetes is also associated with several other metabolic abnormalities such as central obesity, hypertension, and dyslipidemia, which contributes to the very high rate of cardiovascular morbidity and mortality. Therefore Type II diabetes involves a significant financial burden on the health care system. The purpose of this paper is to explain the composition of the healthcare costs of managing people with Type II diabetes and the economic repercussions due to the adoption of an aggressive strategy against the pathology. To carry out this evaluation we considered the CODE-2 (The Cost of Diabetes in Europe - Type II Study results, the American Diabetes Association Position Statement, the Diabetes Prevention Program and the UK Prospective Diabetes Study. Evidence exists to show that introducing prevention program or an early therapy can avert or delay significantly the onset of cardiovascular morbidity in Type II diabetes patients. According to the pharmacoeconomical criteria, this very desiderable clinical goal is associated to a little increase of the health expenditures, and sometimes also to a costs saving.

    In Jodhpur, large number of people suffering with non-insulin dependent diabetes mellitus (type 2 diabetes). They are using medicinal plants along with modern medicine for the management of diabetes. The aim of this work is to document the anti-diabetic plants and determine the most relevant anti-diabetic plant species using the Disease Consensus Index. Ethnomedicinal survey was conducted for selection of anti-diabetic plant. Structured questionnaire was developed for calculation of Disease Consensus Index and administered to fifty Type 2 diabetic patients for recording their response. Twenty-one species of anti-diabetic plants were recorded, Momordica charantia (score: 0.71), Azadirachta indica (score: 0.64), Trigonella foenum-graecum (score: 0.63), Capparis decidua (score: 0.60), Withania coagulans (score: 0.54), Gymnema sylvestre (score: 0.52) and Syzygium cumini (score: 0.51) were the most significant anti-diabetic plants of the area of study, having DCI more than 0.5. Use of anti-diabetic plants is prevalent diabetic patients of the area. C. decidua, W. coagulans and G. sylvestre are recommend the further phytochemical and pharmacological investigation due to high DCI score and relatively unexplored status.

    Full Text Available BACKGROUND It is widely accepted that the dermal ridges develop during early foetal life and are constant (stable throughout life, unique to the individual and therefore significant as a means of identification. It is proved that dermatoglyphics is of polygenic inheritance and like many other hereditary characters show racial and social variations. An attempt has been made to create a database of the dermatoglyphic pattern among the diabetics of Southern Orissa, which may become helpful for the early prediction of the disease and thus prevents its complications. MATERIALS AND METHODS Fifty male diabetic patients diagnosed as cases of insulin-dependent diabetes mellitus (type 1 of age ranging from 25 to 40 years and fifty cases of normal controls of similar age group were included in this study. Similarly, fifty patients diagnosed as cases of non-insulin-dependent type of diabetes mellitus (type 2 of age more than 40 years and fifty cases of normal controls of similar age group without family history of diabetes of either type 1 or type 2 up to two previous generations were studied and analysed in this study. Fifty female diabetic patients diagnosed as IDDM cases of age ranging from 25 to 40 years and fifty cases of normal controls of similar age group and fifty female diabetic patients of type 2 variety (NIDDM and fifty female controls of age group more than 40 years were included in this study. The finger prints and palm prints of the control and patients were taken and studied for different parameters like total ridge count, a-d distance. In type 1 diabetes, the total finger ridge count in male diabetics is more than that in the male controls of similar age group with a level of significant difference being 0.001%. The female diabetics of type 1 variety showed a higher ridge count value in comparison to type 2 male diabetics while the type 1 female diabetics and type 2 female diabetics did not have any significant difference between them in

    1994-04-01

    A cohort of 630 non-diabetic adult Cree and Ojibwa Indians aged 20-64 from 6 remote communities in northern Manitoba and Ontario were followed for 46-63 months. During this period, 22 new cases of clinical diabetes were registered, an incidence density of 8.0/1000 person-years (95% confidence interval 5.8-10.3). Compared to the few published incidence studies, the rate in this population is slightly higher than the "general" North American population but still far below that of the extremely high risk groups such as Pima Indians and Nauruans. On multivariate analyses, fasting plasma glucose (FPG) level and body mass index (BMI) at baseline were significant independent predictors in a multiple logistic regression model that also contained age, sex, total cholesterol, HDL-cholesterol, triglycerides, hypertensive status, waist/hip ratio and subscapular/triceps skin-fold ratio. These associations are in accordance with current knowledge of the pathogenesis of non-insulin-dependent diabetes. This study indicates that a longitudinal follow-up study of a cohort of non-diabetic Native Canadians in remote communities is feasible. Useful data on the etiologic role of various risk factors can be generated which may be used in the planning of intervention programs in the control of this emerging health problem.

    Hyperglycaemia and dyslipidaemia in diabetes mellitus induce increased lipid peroxidation and peroxyl radical formation is an important mechanism in genesis of micro-angiopathy. We took up a study on oxidative stress as measured by lipid peroxidation marker, malondialdehyde (MDA) and antioxidant enzyme status in type 2 diabetes mellitus patients with and without retinopathy and compared them with a control non-diabetic group. MDA was significantly elevated (p diabetic groups whereas antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), catalase (CAT) and reduced glutathione (GSH), etc, were significantly decreased (p diabetes mellitus. The study included 100 subjects of age group 50-70 years, out of which 50 patients were non-insulin dependent diabetes mellitus (NIDDM) with retinopathy and rest 50 age and sex matched apparently healthy individuals (control group). The status of fasting blood sugar (FBS), postprandial blood sugar (PPBS), total cholesterol (TC), triglyceride (Tg), HDL-cholesterol, LDL-cholesterol, VLDL- cholesterol, GPx, GR, CAT, SOD, MDA were determined.

    Full Text Available Background. This study aimed to assess the relationship between diabetes, obesity, and hepatic steatosis in patients undergoing liver resection and to determine if these factors are independent predictors of major complications. Materials and Methods. Analysis of a prospectively maintained database of patients undergoing liver resection between 2005 and 2012 was undertaken. Background liver was assessed for steatosis and classified as <33% and ≥33%. Major complications were defined as Grade III–V complications using the Dindo-Clavien classification. Results. 504 patients underwent liver resection, of whom 56 had diabetes and 61 had steatosis ≥33%. Median BMI was 26 kg/m2 (16–54 kg/m2. 94 patients developed a major complication (18.7%. BMI ≥ 25 kg/m2 (P=0.001 and diabetes (P=0.018 were associated with steatosis ≥33%. Only insulin dependent diabetes was a risk factor for major complications (P=0.028. Age, male gender, hypoalbuminaemia, synchronous bowel procedures, extent of resection, and blood transfusion were also independent risk factors. Conclusions. Liver surgery in the presence of steatosis, elevated BMI, and non-insulin dependent diabetes is not associated with major complications. Although diabetes requiring insulin therapy was a significant risk factor, the major risk factors relate to technical aspects of surgery, particularly synchronous bowel procedures.

  12. Body composition in the pathogenesis and management of diabetes: a Malaysian perspective.

    1994-03-01

    There is an increasing prevalence of diabetes mellitus around the world associated with rapid sociocultural development and changing lifestyles. Increased prevalence of obesity, with a higher consumption of animal products and lower consumption of fruits and vegetables, increases the risk of diabetes mellitus and other chronic degenerative diseases. Insulin-dependent diabetes (IDD) is caused by insulin deficiency, whereas the main feature of non-insulin-dependent diabetes (NIDD) which accounts for more than 90% of diabetics, is hyperinsulinemia and insulin resistance, which may eventually lead to actual insulin deficiency. Hyperinsulinemia is undesirable because it increases the risk of developing vascular disease. In Malaysia, the prevalence of NIDD in some communities now exceeds 5%, and of impaired glucose tolerance 10%. Along with these increases in prevalence of hyperglycemia are increases in prevalence of overweight (BMI>25) and almost certainly abdominal fatness. In terms of management, nutrition is given priority. Insulin and hypoglycemic drugs (sulphonylureas or biguanides), where required, may adversely affect body composition if overused. Newer therapeutic strategies require greater attention to the underlying problem in NIDD of abdominal fatness by attention to the relevant nutritional factors, physical activity and other lifestyle factors like cigarette smoking and alcohol. The greater impact of obesity and diabetes on Malaysian women as opposed to men also needs to be addressed.

    There are two insulin receptor (IR) isoforms (designated type A and type B), derived from alternative splicing of exon 11 of the IR gene. Recently, we reported that an increase in the exon 11- (i.e. lacking exon 11) (type A) IR messenger RNA (mRNA) variant in muscle is associated with hyperinsulinemia, an early risk factor for noninsulin-dependent diabetes mellitus (NIDDM), in the spontaneously obese, diabetic rhesus monkey. To explore further the role of IR mRNA splicing in insulin resistance of NIDDM, we studied liver, another target organ that is resistant to insulin action in NIDDM. The relative amounts of the two IR mRNA-splicing variants in liver were quantitated by RT-PCR in normal, prediabetic, and diabetic (NIDDM) monkeys. The percentage of the exon 11- mRNA variant in liver (n = 24) was significantly correlated with fasting plasma glucose (r = 0.55, P < 0.01) and intravenous glucose disappearance rate (r = -0.45, P < 0.05). The exon 11- mRNA variant was increased significantly from 29.8 {+-} 1.6% in monkeys with normal fasting glucose to 39.2 {+-} 2.9% in monkeys with elevated fasting glucose (P < 0.01). These studies provide the first direct evidence in vivo that the relative expression of the two IR mRNA-splicing variants is altered in liver and suggest that increased expression of the exon 11- IR isoform may contribute to hepatic insulin resistance and NIDDM or may compensate for some yet unidentified defect. 33 refs., 3 figs., 1 tab.

    Full Text Available Background: Genome – wide analysis of genetic predisposition to type 2 diabetes mellitus in different populations have yielded variable results. Calpain10, a gene that encodes a non-lysosomal cysteine protease, has been recently proposed as a type 2 diabetes susceptibility genes in the non-insulin-dependent diabetes mellitus NIDDM1 region. Aim of the study is to evaluate the relation between SNP43 and type2 diabetes. Methods: A total of 102 diabetic subjects and 100 undiabetic controls enrolled in a case-control study in Eastern Azerbaijan Azerbaijan Province. The polymerase chain reaction restriction fragment length polymorphism technique (PCR–RFLP was applied. We use X2 test and logistic regression to analysis of data. Results: Genotypes distribution of calpain10 gene in control group were 11(11%, 86(86% and 3(3% with respected to A/G, G/G and A/A genotypes, respectively. In diabetic group genotypes distribution were 7(6.9%, 95(93.1% and zero, respectively. The G allele frequency was significant difference in case and control groups. Conclusion: Since G allele is a risk factor to affect type 2 diabetes disease hence SNP43 of calpain10 gene had significant association with type 2 diabetes in Eastern Azerbaijan.

    Diabetes Mellitus type 2 , formerly non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes, is a metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency1. The development of Diabetes Mellitus type 2 is associated with multiple risk factors, co-morbid medical conditions as well as psychosocial determinants. These psychosocial factors, which differ from population to population, can be identified and controlled to reduce the incidence of type 2 Diabetes Mellitus. Objective: To identify various psychosocial factors associated with type 2 Diabetes Mellitus. Design: Case-control study. Place and Duration: Diabetic clinic and Medical Units Mayo Hospital Lahore . July to December, 2012. Subjects and Methods: A population based case-control study with 1:1 case to control ratio was conducted. A total of 100 subjects (50 cases and 50 controls) having age above 35 years were recruited in the study. Selection was made on laid down criteria from patients coming to Mayo Hospital Lahore after taking consent. Interviews were conducted through a pretested questionnaire. Data was collected, compiled and analyzed through IBM SPSS version 20. Results: Out of 100 study subjects 67% were males and 33% were females. Among cases of Diabetes mellitus type 2, 64% were males, 70% in the age group 35-50 years, 96% were married, 36% were illiterates. Mean age was found 49.24, standard deviation 10.915. In bivariate analysis, Diabetes Mellitus type II was found significantly associated with Anxiety(OR: 5.348, 95% CI: 2.151-13.298) Depression(OR: 5.063, 95% CI: 1.703-15.050), High fat diet, (OR: 2.471, 95% CI: 1.100-5.547) Sedentary Lifestyle(OR: 4.529, 95% CI: 1.952-10.508) and Psychological Stress(OR:4.529, 95% CI: 1.952-10.508).

    The effect of the angiotensin converting enzyme inhibitor captopril (25 mg by mouth) on glucose metabolism of skeletal muscle and the whole organism was studied in nine normotensive type II (non-insulin dependent) diabetics using a combination of euglycaemic-hyperinsulinaemic glucose-clamp and forearm catheter techniques. The administration of captopril resulted in a significant rise of both the whole-body glucose elimination and utilization rate in the forearm musculature. At the same time the arterial kinin level rose, while the concentrations of insulin, free fatty acids and gluconeogenesis precursors, as well as the number and activity of insulin receptors (measured in an erythrocyte-binding study) remained unchanged. The data support the view that, in type II diabetics, ACE inhibition raises the insulin-stimulated glucose uptake of the whole organism, predominantly due to an increased glucose uptake by the skeletal musculature. The demonstration of an increased kinin level points to this effect possibly being caused by the reduced breakdown of locally liberated kinins.

    The patients suffered from diabetes mellitus (DM) are increasing year by year through the world. DM is classified into two groups, insulin-dependent type 1 and non-insulin-dependent type 2. Recent research has demonstrated that vanadate (VO3-, oxidation state+5) and vanadyl (VO2+, oxidation state+4) both mimic various actions of insulin in cellular systems. In 1985, vanadate given orally as a drinking water to streptozotocin-induced hyperglycemic type 1 diabetic rats (STZ-rats) was found to reduce the high levels of blood glucose down to normal levels and ameliorated many of the aberrations induced by hyperglycemia. In 1990, we proposed first orally active vanadyl complexes such as vanadyl-cysteine methylester and vanadyl-oxalate complexes in STZ-rats. Since then, we have developed orally active vanadyl complexes with different coordination modes. Among them, vanadyl-picolinate complexes with VO(N2O2) coordination mode were found to be potent orally active insulin-mimetic agents, on the basis of the results on in vitro test using isolated rat adipocytes with respect to the inhibition of the release of free fatty acids (FFA) from the cells and in vivo evaluation (intraperitoneal injection and oral administration) in STZ-rats. Based on the results, the usefulness of vanadium complexes in treating and preventing DM has been revealed, proposing a possible action mechanism.

    Pancreatic islets from healthy (control) and neonatally streptozocin-induced diabetic (STZ-D) rats, a model for non-insulin-dependent diabetes mellitus, were incubated with 3 H 2 O and 5.5 or 16.7 mM glucose. At 5.5 mM glucose, no detectable [ 3 H]glucose was formed. At 16.7 mM, 2.2 patom.islet-1.h-1 of 3 H was incorporated into glucose by the control islets and 5.4 patom.islet-1.h-1 by STZ-D islets. About 75% of the 3 H was bound to carbon-2 of the glucose. Glucose utilization was 35.3 pmol.islet-1.h-1 by the control and 19.0 pmol.islet-1.h-1 by the STZ-D islets. Therefore, 4.5% of the glucose-6-phosphate formed by the control islets and 15.7% by the STZ-D islets was dephosphorylated. This presumably occurred in the beta-cells of the islets catalyzed by glucose-6-phosphatase. An increased glucose cycling, i.e., glucose----glucose-6-phosphate----glucose, in islets of STZ-D rats may contribute to the decreased insulin secretion found in these animals

    In non-insulin-dependent diabetes mellitus (NIDDM), there is a clustering of an elevated urinary albumin excretion rate (U-AER) in nondiabetic relatives of albuminuric patients. Whether this is also the case in insulin-dependent diabetes mellitus (IDDM) is unknown. Overnight U-AER was measured in 186 nondiabetic first-degree relatives of 80 IDDM patients with diabetic nephropathy (U-AER > 200 microg/min or 300 mg/24 hours; DN+) and in 52 relatives of 25 IDDM patients without nephropathy (U-AER therapy, and smoking habits. No difference was found in overnight U-AER between relatives of patients with DN+ and DN- [median (range), 3.4 (0.1 to 372) vs. 4.0 (0.2 to 62) microg/min, respectively, P = NS]. The proportion of relatives with a U-AER = 10 microg/min was 12% in DN+ compared with 8% in DN- (P = NS). Among relatives of DN+, those with antihypertensive treatment (AHT+) had higher U-AER compared with those without [AHT+ vs. AHT-, 5.0 (0.5 to 372) vs. 3.4 (0.1 to 26.5) microg/min, P AER in nondiabetic relatives of patients with nephropathy. This is different from what has been reported in NIDDM, and suggests heterogeneity in the genesis of albuminuria in diabetes.

Methods: All the extracts were administered in different doses (100, 200 and 400 mg/kg, p.o. to investigate the ulcer healing potential. Streptozotocin (STZ; 65 mg/kg, i.p. along with nicotinamide (120 mg/kg, i.p. was used to induce non-insulin dependent diabetes mellitus in rats. Aspirin (200 mg/kg, i.p. was administered for initial 7 d to induce gastric ulcerations in the diabetic rats. Various biochemical markers of blood and tissue origin were estimated to compare the ulcer healing potential of these extracts. Results: The OMO and OMM exhibited dose dependent significant (P<0.01 ulcer healing property than the OMW. Additionally, the antidiabetic property of OMO and OMM was better than OMW. Conclusions: The OMO and OMM of Origanum majorana leaves can prove to be beneficial in the concomitant treatment of gastric ulcers and diabetes.

    To assess salivary flow in older patients with type 2 diabetes mellitus (DM2) and its association with xerostomia. Cross-sectional clinical study conducted with older patients diagnosed with type 2 diabetes for at least one year receiving treatment at the Integrated Center for Diabetes and Hypertension of Ceará (CIHD) in the city of Fortaleza, Ceará, Northeastern Brazil. Oral clinical examination was carried out to assess the decayed, missing and filled teeth index (DMFT). Perception of the presence of xerostomia/dry mouth was assessed using the Visual Analogue Scale. Stimulated salivary flow was measured and samples were obtained using an extra-soft silicone device. 120 older patients with diabetes (60 insulin-dependent and 60 non-insulin-dependent) aged 65-91 years, with a mean age of 72.26 ± 6.53 years, were assessed. Of these, 111 (92.5%) presented a decrease in salivary flow while 59 (49.2%) reported moderate to severe xerostomia/dry mouth. The DMFT Index presented a mean of 27.53 ± 4.86 teeth. Reduced salivary flow was found in the group assessed in the present research; however, this finding is not in accordance with the perception of xerostomia/dry mouth reported by the patients.

    Spontaneous pneumothorax is infrequently caused by strenuous exertion. To our knowledge there has only been one case of spontaneous pneumothorax associated with weightlifting reported in the medical literature. We describe three consecutive cases of spontaneous pneumothorax associated with weightlifting. We postulate that spontaneous pneumothorax in these patients may be secondary to improper breathing techniques. It is important that physicians and weight trainers be aware of the association between weight lifting and spontaneous pneumothorax and assure that proper instruction is given to athletes who work with weights.

    Gastric emptying of technetium labeled liquid meal were studied in 46 non-insulin-dependent diabetics, 7 obese patients, 8 anorexia nervosa patients, and 21 normal subjects. All subjects underwent endoscopy and barium study, and none showed any lesion in upper gastrointestinal tract. T1/2, time at which 50% of meal remained, was used as an indicator of gastric emptying. Eight normal subjects have some epigastric discomforts, and have slightly slower gastric emptying than the remaining 13 subjects. But there was no significant difference in T1/2 between the both groups (53.2+-12.8 min vs 45.1+-10.9 min). Fourteen diabetics have some epigastric discomforts, and have significantly more slower gastric emptying than the remaining 32 diabetics (T1/2; 67.7+-24.6 vs 50.5+-17.4, p<0.02). The gastric emptying of 13 diabetics who have three major diabetic complications (retinopathy, nephropathy, and peripheral neuropathy), was significantly more slower than that of 15 diabetics without any complication (T1/2; 68.1+-24.6 vs 43.5+-14.8, p<0.005). The gastric emptying of simple obesity did not show a fixed pattern, but the emptying of anorexia nervosa was remarkably delayed. These findings indicate that diabetic gastroparesis is common in the presence of the three major complications, and the delayed gastric emptying is associated with post-prandial discomfort in diabetics and anorexia nervosa patients. The measurement of gastric emptying can be useful to evaluate the management and the treatment for diabetes and anorexia nervosa. (author).

    Full Text Available Abstract Background The prevalence of rotator cuff tears increases with age and several studies have shown that diabetes is associated with symptomatic shoulder pathologies. Aim of our research was to evaluate the prevalence of shoulder lesions in a population of asymptomatic elderly subjects, normal and with non insulin - dependent diabetes mellitus. Methods The study was performed on 48 subjects with diabetes and 32 controls (mean age: 71.5 ± 4.8 and 70.7 ± 4.5, respectively, who did not complain shoulder pain or dysfunction. An ultrasound examination was performed on both shoulders according to a standard protocol, utilizing multiplanar scans. Results Tendons thickness was greater in diabetics than in controls (Supraspinatus Tendon: 6.2 ± 0.09 mm vs 5.2 ± 0.7 mm, p vs 3.2 ± 0.4 mm, p vs 20.3%, p vs 7.8%, p Subjects with diabetes exhibited more tears in the Supraspinatus Tendon (Minor tears: 15 (15.8% vs 2 (3.1%, p vs 5 (7.8%, p = ns, but not in the long head of Biceps. More effusions in subacromial bursa were observed in diabetics (23.9% vs 10.9%, p vs 10.9%, p In both groups, pathological findings were prevalent on the dominant side, but no difference related to duration of diabetes was found. Conclusions Our results suggest that age - related rotator cuff tendon degenerative changes are more common in diabetics. Ultrasound is an useful tool for discovering in pre - symptomatic stages the subjects that may undergo shoulder symptomatic pathologies.

    Through experiment on animals and clinical trials to explore the safety and efficacy of hypoglycemic anti-deafness capsules on diabetic patients with deafness. Total 296 patients with non-insulin dependent diabetes mellitus (NIDDM) were randomly divided into two groups. A treatment group of 164 patients (208 ears) was treated with hypoglycemic anti-deafness capsules based on TCM syndrome differentiation. A control group of 132 patients (184 ears) was treated with glibenclamide and conventional drug treatment for deafness. The following were observed: hearing, fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2hPG), 24 h urine glucose (24hUG), improvement of main symptoms, platelet function, and changes in superoxide dismutase (SOD) and lipid peroxide (LPO) levels. In animal studies, Kunming mice, weighing 18-22 g were used. Half of the mice were males and half were females. Wistar rats, weighing 80-120 g were used. Half of the rats were males and half were females. Male Wistar rats, weighing 200-220 g, were also used. Their acute and chronic toxicity was studied. The hearing improvement was 56.7% in the treatment group and 26.6% in the control group. FPG, 2hPG, and 24hUG were improved significantly (P deafness capsules could decrease blood glucose and serum triglycerides of alloxan-induced diabetic rats. This herbal capsule is effective for safely treating diabetic patients with deafness.

    Periodontal disease is a common infection-induced inflammatory disease among individuals suffering from diabetes mellitus. The purpose of this study was to assess the effects of treatment of periodontal disease on the level of metabolic control of diabetes. A total of 113 Native Americans (81 females and 32 males) suffering from periodontal disease and non-insulin dependent diabetes mellitus (NIDDM) were randomized into 5 treatment groups. Periodontal treatment included ultrasonic scaling and curettage combined with one of the following antimicrobial regimens: 1) topical water and systemic doxycycline, 100 mg for 2 weeks; 2) topical 0.12% chlorhexidine (CHX) and systemic doxycycline, 100 mg for 2 weeks; 3) topical povidone-iodine and systemic doxycycline, 100 mg for 2 weeks; 4) topical 0.12% CHX and placebo; and 5) topical water and placebo (control group). Assessments were performed prior to and at 3 and 6 months after treatment and included probing depth (PD), clinical attachment level (CAL), detection of Porphyromonas gingivalis in subgingival plaque and determination of serum glucose and glycated hemoglobin (HbA1c). After treatment all study groups showed clinical and microbial improvement. The doxycycline-treated groups showed the greatest reduction in probing depth and subgingival Porphyromonas gingivalis compared to the control group. In addition, all 3 groups receiving systemic doxycycline showed, at 3 months, significant reductions (P periodontal infection and reduction of periodontal inflammation is associated with a reduction in level of glycated hemoglobin. Control of periodontal infections should thus be an important part of the overall management of diabetes mellitus patients.

    Full Text Available Ankle fractures represent 9% of fractures. Even if it is a relatively usual fracture, the presence of diabetes makes treatment more difficult and rate of complications is higher than in the rest of population. The incidence of ankle fractures increased in the last half century. Many studies from SUA, England, Sweden and Finland suggest that the epidemiology of ankle fractures continues to change as populations age, up to the age 60 of years in men and above age of 50 years in women. Two-thirds of fractures are isolated malleolar fractures, bimalleolar fractures occur in one-fourth of patients and trimaleolar fractures occur in the rest of them. We present a case of 60 years old women with non-insulin dependent diabetes for 22 years who sustained a fracture of ankle. Her first presentation at doctor was after 4 months after injury and surgical treatment occurred after 8 months after the injury. She was operated using an external fixator. Despite the fact the treatment was delayed, the evolution of lesion was good and patient could regained normal gate.

    The effects of pioglitazone, a very used drug in the treatment of non-insulin dependent diabetes mellitus, were tested at the level of ovary of non-pregnant female rats. The experiment was performed on three groups of adult non-pregnant female rats. group 1 was a control group (and did not receive any substance), group 2 received streptozotocin 60 mg/kg i.p. (single administration), and group 3 received streptozotocin 60 mg/kg i.p. (single administration) and pioglitazone 5 mg/kg/day p.o., daily for 8 weeks. The plasma glucose, cholesterol and triglyceride levels were determined before drugs administration and during the experiment. After 8 weeks the animals were anesthetized and sacrificed. The ovaries were examined by optical microscopy. A morphometric evaluation was performed. The obtained data were statistically interpreted by ANOVA test. After 8 weeks of treatment the plasma glucose and triglyceride levels were significantly lower in the pioglitazone treated group compared to the streptozotocin only group. In the pioglitazone group the number of primordial and primary ovarian follicles was significantly higher than in streptozotocin only group. The results showed a partial protective action of pioglitazone on ovary in nonpregnant diabetic female rats.

Methods: We adopt a retrospective cohort study involving 280 type-2 diabetes patients who regularly used the outpatient services of one medical center and who had changed metformin brands five times between 2003 and 2008. The aim was to examine the effects of switching brands. The generalized estimating equation was used to determine whether drug brand switching affected patient glycated hemoglobin A1c (HbA1c levels, their prescribed daily dose, or their adherence to medication with metformin. Results: HbA1c levels increased from 7.91 to 8.34 throughout the study period, although it was found that brand switching did not adversely affect HbA1c levels after controlling for patient characteristics and the time course of the study. Furthermore, the prescribed daily dose of metformin was stable throughout the study period, and was approximately 0.8 of the defined daily dose. Finally, although adherence was significantly higher with the original metformin than with the four generic brands, patients still maintained high levels of adherence of >0.8. Conclusion: Although switching between different brands of metformin slightly affected the prescribing behavior of the physicians, there was no unfavorable effect on patient HbA1c levels. Thus, the policy of substituting between different generic brands of metformin is a good cost-effective approach that does not adversely affect the quality of diabetes patient care.

  18. Hydrogen improves glycemic control in type1 diabetic animal model by promoting glucose uptake into skeletal muscle.

    Full Text Available Hydrogen (H(2 acts as a therapeutic antioxidant. However, there are few reports on H(2 function in other capacities in diabetes mellitus (DM. Therefore, in this study, we investigated the role of H(2 in glucose transport by studying cultured mouse C2C12 cells and human hepatoma Hep-G2 cells in vitro, in addition to three types of diabetic mice [Streptozotocin (STZ-induced type 1 diabetic mice, high-fat diet-induced type 2 diabetic mice, and genetically diabetic db/db mice] in vivo. The results show that H(2 promoted 2-[(14C]-deoxy-d-glucose (2-DG uptake into C2C12 cells via the translocation of glucose transporter Glut4 through activation of phosphatidylinositol-3-OH kinase (PI3K, protein kinase C (PKC, and AMP-activated protein kinase (AMPK, although it did not stimulate the translocation of Glut2 in Hep G2 cells. H(2 significantly increased skeletal muscle membrane Glut4 expression and markedly improved glycemic control in STZ-induced type 1 diabetic mice after chronic intraperitoneal (i.p. and oral (p.o. administration. However, long-term p.o. administration of H(2 had least effect on the obese and non-insulin-dependent type 2 diabetes mouse models. Our study demonstrates that H(2 exerts metabolic effects similar to those of insulin and may be a novel therapeutic alternative to insulin in type 1 diabetes mellitus that can be administered orally.

    Full Text Available In 1991 the prevalence of diabetes was 7.6% in women in nine Brazilian state capitals. This disease now ranks among the leading causes of death in the country and is becoming an increasingly alarming public health problem. In spite of advances in the treatment of diabetes and improved obstetric care, gestational diabetes puts a pregnant woman at high risk of miscarriage, ketoacidosis, hypoglycemia, hypertension, and other serious disorders. This study used life histories to investigate the relationship between health, sexuality, and work in five working women who were diabetic and pregnant and who received care at the Prenatal Care Outpatient Clinic of the San Pablo Hospital. These women all had non-insulin-dependent diabetes mellitus, were between 26 and 43 years old, and earned from US$ 150 to US$ 375 per month for working 8-hour days, with one day off each week. Two of the women’s male partners were unemployed; all of the women performed household chores during their day off. Quotations taken directly from conversations with the five participants reveal the difficulty of caring for children while holding down a job; the sexual harassment that some of the women suffered; the conflict and dissatisfaction associated with work; the myth of the natural joy of motherhood; the sexual control exercised by males; the incompatibility of working conditions and work activities with pregnancy; and the perception that they did not have legal protection owing to employers’ lack of respect for workers’ rights and for the maternity protection provisions of the Federal Constitution of Brazil. It is concluded that health policies should pay greater attention to improving the quality of life of working women, especially if they suffer from diabetes and are pregnant.

  20. Meglumine exerts protective effects against features of metabolic syndrome and type II diabetes.

    Arturo Bravo-Nuevo

    Full Text Available Metabolic syndrome, diabetes and diabetes complications pose a growing medical challenge worldwide, accentuating the need of safe and effective strategies for their clinical management. Here we present preclinical evidence that the sorbitol derivative meglumine (N-methyl-D-glucamine can safely protect against several features of metabolic syndrome and diabetes, as well as elicit enhancement in muscle stamina. Meglumine is a compound routinely used as an approved excipient to improve drug absorption that has not been ascribed any direct biological effects in vivo. Normal mice (SV129 administered 18 mM meglumine orally for six weeks did not display any gastrointestinal or other observable adverse effects, but had a marked effect on enhancing muscle stamina and at longer times in limiting weight gain. In the established KK.Cg-Ay/J model of non-insulin dependent diabetes, oral administration of meglumine significantly improved glycemic control and significantly lowered levels of plasma and liver triglycerides. Compared to untreated control animals, meglumine reduced apparent diabetic nephropathy. Sorbitol can improve blood glucose uptake by liver and muscle in a manner associated with upregulation of the AMPK-related enzyme SNARK, but with undesirable gastrointestinal side effects not seen with meglumine. In murine myoblasts, we found that meglumine increased steady-state SNARK levels in a dose-dependent manner more potently than sorbitol. Taken together, these findings provide support for the clinical evaluation of meglumine as a low-cost, safe supplement offering the potential to improve muscle function, limit metabolic syndrome and reduce diabetic complications.

    To determine whether glycemic control in adults with either insulin-dependent diabetes mellitus (IDDM) or non-insulin-dependent diabetes mellitus (NIDDM) is related to perceived family function, stress/coping, affect, and locus of control. Cross-sectional, observational study. Four hundred seven subjects from a family medicine ambulatory care unit, a tertiary pediatric diabetic unit, or a public-funded community health center, all located in Winston-Salem, NC, completed a series of psychometric instruments that included the Family APGAR (Adaptation, Partnership, Growth, Affection, and Resolve), FACES III (Family Adaptability and Cohesion Evaluation Scales) Cohesion subscale, Affect Balance Scale, Multidimensional Health Locus of Control Scales, and the Brief Encounter Psychosocial Instrument. Glycemic control was measured by fasting blood glucose levels and glycosylated hemoglobin A1C levels as well as by patients' perception of their control. Those with NIDDM had scores indicative of more external sources of control than those with IDDM. A greater proportion of adults with both subtypes of diabetes perceived their families to be disengaged than subjects from families without diabetes. In a bivariate analysis, family dysfunction correlated with lack of perceived glycemic control, while perceived stress and negative affect correlated with fasting glucose levels in those with NIDDM but not those with IDDM. Using multivariate discriminant analysis, adults with NIDDM in good glycemic control as measured by glycosylated hemoglobin levels had lower family cohesion and negative affect than those in poor control. Conversely, those with IDDM with acceptable glycosylated hemoglobin levels had higher family cohesion, less negative affect, fewer chance loci of control, but higher perception of inadequate coping than those in poor control. Knowledge of the family function, affect, locus of control, perceived stress, and coping may be useful to the family physician in the care

    Objectives To investigate patterns of self monitoring of blood glucose concentration in diabetic patients who use insulin and to determine whether frequency of self monitoring is related to glycaemic control. Setting Diabetes database, Tayside, Scotland. Subjects Patients resident in Tayside in 1993-5 who were using insulin and were registered on the database and diagnosed with insulin dependent (type 1) or non-insulin dependent (type 2) diabetes before 1993. Main outcome measures Number of glucose monitoring reagent strips dispensed (reagent strip uptake) derived from records of prescriptions. First recorded haemoglobin A1c concentration in the study period, and reagent strips dispensed in the previous 6 months. Results Among 807 patients with type 1 diabetes, 128 (16%) did not redeem any prescriptions for glucose monitoring reagent strips in the 3 year study period. Only 161 (20%) redeemed prescriptions for enough reagent strips to test glucose daily. The corresponding figures for the 790 patients with type 2 diabetes who used insulin were 162 (21%; no strips) and 131 (17%; daily tests). Reagent strip uptake was influenced both by age and by deprivation category. There was a direct relation between uptake and glycaemic control for 258 patients (with recorded haemoglobin A1c concentrations) with type 1 diabetes. In a linear regression model the decrease in haemoglobin A1c concentration for every extra 180 reagent strips dispensed was 0.7%. For the 290 patients with type 2 diabetes who used insulin there was no such relation. Conclusions Self monitoring of blood glucose concentration is associated with improved glycaemic control in patients with type 1 diabetes. Regular self monitoring in patients with type 1 and type 2 diabetes is uncommon. Key messagesSeveral studies have indicated the importance of self monitoring of blood glucose concentration for prevention of complications in patients with diabetesUptake of reagent strips for self monitoring of blood glucose

  3. Are we closer to finding the treatment for type 2 diabetes mellitus in morbid obesity? Are the incretins the key to success?

    Morbid obesity is a serious health problem associated with disease and mortality. One such disease is non-insulin-dependent diabetes mellitus (NIDDM). Approximately 95% of American diabetics have NIDDM. One of the major causes for type 2 diabetes is obesity. The improvement of diabetes with weight control is not in the earliest description of the disease. However, dietary control of NIDDM is often disappointing. Diet can improve glucose metabolism in obesity, but the improvement usually represents only a portion or a brief return to euglycemia, even when patients appear to be compliant. In contrast, reversal of NIDDM has been much more successfully achieved after bariatric surgery. Intra-abdominal fat deposition is associated with increased plasma concentration of free fatty acids, which reduce insulin sensitivity at both muscular and hepatic sites. The progression of diabetes is heralded by the inability of the beta-cells to maintain their previously high rate of insulin secretion in response to glucose, in the face of insulin resistance. The propensity to develop type 2 diabetes may be genetically determined or triggered by environmental factors. The connection between diabetes and obesity represents a continuum that progresses through different phases in which defective insulin action is the principal problem. At this point, we are unable to correlate the different findings of the many questions that arise, such as: 1) Does the decrease in sensitivity to insulin result from rearrangement of the insulin receptor? 2) Is weight loss the trigger for decrease of insulin resistance? 3) Is rearrangement of part of the intestine a mechanism to trigger the secretion of hormones (incretins) that help in insulin response? 4) Which mechanism controls the insulin resistance? The goal of this paper is to review literature on incretins and address the role of incretins after bariatric surgery. We know very little about the action of incretins in diabetes. We will assess the

    The recent discoveries about the structure of Rh protein that suggest a transport function and the recent observations of a positive correlation between Rh(D) protein and glycosylated hemoglobin levels in non-insulin-dependent diabetes mellitus prompted us to review our data on diabetic pregnancy to evaluate the perinatal consequences of maternal-fetal Rh blood group interactions in a metabolic perspective. One hundred thirty-two women with gestational diabetes and 120 women with preexisting insulin-dependent diabetes mellitus were examined. Three hundred eighty-seven consecutive nondiabetic puerperae from the same population were considered control subjects. In both gestational and insulin-dependent diabetes mellitus, an increased proportion of mother Rh(+)/newborn Rh(-) and a decreased proportion of mother Rh(-)/newborn Rh(+) joint phenotype has been observed. No deviation has been observed for joint phenotypes in which mother and newborn are similar [ie, Rh(+)/Rh(+) and Rh(-)/Rh(-)]. In the situation of mother Rh(+)/newborn Rh(-), there is a relatively lower rate of fetal loss and a decreased tendency to high birth weight. On the contrary, in pairs mother Rh(-)/newborn Rh(+) the fetus shows an increase of fetal loss and of tendency to high birth weight. The results are compatible with the hypothesis that when the density of Rh protein in the mother is higher than that in the fetus, the conceptus is relatively protected against the toxic effect of glucose. In the opposite genotypic combination (ie, density of Rh protein higher in the fetus than in the mother), the fetus is relatively more susceptible to these effects.

    Inappropriate body weight gain during pregnancy has critical effects on the outcome for both mother and fetus. Therefore, body weight gain is an important issue in the management of pregnancy in women with diabetes. A Trp64Arg substitution in the beta3-AR gene has been reported to be associated with body weight gain and obesity in non-insulin-dependent diabetes mellitus (NIDDM) subjects. The aim of this study was to elucidate the contribution of the beta3-AR gene to body weight gain during pregnancy in subjects with diabetes. We analyzed 199 diabetic patients (NIDDM/IDDM; 131/68) and patient data was obtained from the first delivery of each individual. The mean age at diagnosis of diabetes was 22.9 +/- 7.5 years (mean +/- S.D.) and the mean age at delivery was 29.8 +/- 4.5 years. A polymorphism of the beta3-AR gene was detected by PCR-RFLP using Bst OI, which recognizes a Trp64Arg substitution. The frequency of the Trp64Arg allele was 0.15 in NIDDM and 0.17 in IDDM. Among the NIDDM subjects, excess weight gain during pregnancy, as defined by maximum BMI during pregnancy minus basal BMI before pregnancy exceeding five, was observed in 12.2% of the wild-type patients, 19.2% of heterozygotes and 28.6% of homozygotes. Homozygous subjects with NIDDM tended to show excess weight gain during pregnancy, however, this trend did not reach significance. None of the IDDM homozygotes showed excess weight gain. From our study, this beta3-AR gene polymorphism cannot be excluded as a contributing factor to excess weight gain during pregnancy in NIDDM subjects.

    We report on the use of intravenous (IV) high-dose lidocaine to relieve diabetic neuropathic pain, and the technique's effects on clinical measures of lipid peroxidation. Under continuous electrocardiogram monitoring, IV lidocaine (5 mg kg(-1) in 100 mL saline) was administered over 30 minutes to 7 non-insulin-dependent diabetic patients suffering from neuropathic pain who reported increased pain within the preceding 6 months. This treatment was performed once a week for 1 month. Blood samples were collected from the contralateral limb to determine plasma superoxide dismutase (SOD) and malondialdehyde (MDA) levels on admission and following the final lidocaine administration. Plasma MDA concentrations significantly decreased after the final IV lidocaine treatment (P < .05, paired t-test), whereas SOD levels did not show a statistically significant difference compared with baseline levels. High-dose lidocaine treatment lessens MDA levels, a marker of free-radical-mediated cell damage. This suggests that one of lidocaine's mechanism of action may be its effect on oxygen free radicals, which in turn impacts lipid peroxidation.

    Full Text Available Spontaneous atraumatic mediastinal hematomas are rare. We present a case of a previously fit and well middle-aged lady who presented with acute breathlessness and an increasing neck swelling and spontaneous neck bruising. On plain chest radiograph, widening of the mediastinum was noted. The bruising was later confirmed to be secondary to mediastinal hematoma. This life-threatening diagnostic conundrum was managed conservatively with a multidisciplinary team approach involving upper gastrointestinal and thoracic surgeons, gastroenterologists, radiologists, intensivists, and hematologists along with a variety of diagnostic modalities. A review of literature is also presented to help surgeons manage such challenging and complicated cases.

    Spontaneous bacterial peritonitis occurs in 30% of patients with ascites due to cirrhosis leading to high morbidity and mortality rates. The pathogenesis of spontaneous bacterial peritonitis is related to altered host defenses observed in end-stage liver disease, overgrowth of microorganisms, and bacterial translocation from the intestinal lumen to mesenteric lymph nodes. Clinical manifestations vary from severe to slight or absent, demanding analysis of the ascitic fluid. The diagnosis is confirmed by a number of neutrophils over 250/mm3 associated or not to bacterial growth in culture of an ascites sample. Enterobacteriae prevail and Escherichia coli has been the most frequent bacterium reported. Mortality rates decreased markedly in the last two decades due to early diagnosis and prompt antibiotic treatment. Third generation intravenous cephalosporins are effective in 70% to 95% of the cases. Recurrence of spontaneous bacterial peritonitis is common and can be prevented by the continuous use of oral norfloxacin. The development of bacterial resistance demands the search for new options in the prophylaxis of spontaneous bacterial peritonitis; probiotics are a promising new approach, but deserve further evaluation. Short-term antibiotic prophylaxis is recommended for patients with cirrhosis and ascites shortly after an acute episode of gastrointestinal bleeding.

    Over the past few years, evidence has begun to accumulate suggesting that spacetime may undergo a "spontaneous dimensional reduction" to two dimensions near the Planck scale. I review some of this evidence, and discuss the (still very speculative) proposal that the underlying mechanism may be related to short-distance focusing of light rays by quantum fluctuations.

    Full Text Available The coronary heart disease (CHD is a leading cause of lethality in both sexes. The risk for development of CHD is 2-4 times higher in non insulin dependent diabetes mellitus (NIDDM than in nondiabetics, and annual rate of fatal and non-fatal cardiovascular diseases in NIDDM is 2-5%. The etiology of CHD is still unknown until the risk factors connected to the development of CHD are well known.The purpose of this research was to establish the frequency and importance of the risk factors in development of CHD in NIDDM.The research included 60 patients with NIDDM who were by presence of CHD classified into two groups. We determined body mass index and waist hip ratio, total and HDL cholesterol, triglicerides, LDL cholesterols, uric acid and fibrinogen.Values of BMI were statistically higher in patients with CHD than in diabetics without CHD 29.67+3.31 vs. 27.87±3.17 kg/m2 (p<0.05. Raised risk levels of cholesterol had90% with CHD and 76% without CHD (Hi2=6.12, p<0.05. Larger percentage of patients in group with CHD had raised lipid risk levels of triglicerides 70% than in patients without CHD 56.5% (Hi2=4.36, p<0.05. The obesity was relatively rare in patients without CHD than in diabetics with CHD (13.6% vs. 76%, p<0.01.The frequency of risk factors was very high in NIDDM patients, which clearly points at their cumulative effect in development of CHD in diabetics.

    Background: In Pakistan, approximately 8 million people have diabetes mellitus, making it the fourth leading country in the list of world diabetic patients. Objectives: To measure the prevalence of diabetes mellitus and its associated risk factors in a rural community of Peshawar. Study type, settings: A cross-sectional study conducted in PMRC model research community village of Budhni. Subjects and Methods: All adults over the age of 40 years residing in the specific village were selected for the study. During door to door visit, consent was taken from all the subjects and they were informed that a fasting blood sugar level would be checked a day or two later. All those who consented were interviewed according to pre-designed proforma and their height, weight and blood pressure were recorded using standard methods. Fasting blood samples were drawn the next day and sent to PMRC research laboratory where they were checked using Microlab 200 Merck. Data was analyzed using Epi Info version 6.0. According to American Diabetic Association criteria, fasting blood sugar level of >126 mg/dl was diagnosed. Results: Estimated population of adults > 40 years in the village is 1249 individuals. Nine hundred nine (72.7%) consented to participate in the study. A total of 345 subjects were screened for diabetes using fasting blood sugar as the proxy indicator. Eighty one (23.4%) had blood sugar over 126 mg/dl and were therefore, diagnosed to be diabetic. Of these 81 cases 46(56.8%) were known diabetics while, 35(43.2%) were newly diagnosed. Majority (39) were between 51-60 years, followed by 29 between 40-50 years and remaining 13 subjects were above 60 years of age. Among the 46 known diabetics, 42(91.3%) were non insulin dependent and only 4(8.7%) were insulin dependent. The duration of diabetes was between 1-5 years in 26(57%) cases who were known diabetic's. Those individuals who were not sure about their exact duration of diabetes were 9(19%). Cases with a family history of

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and sudden cardiac death. It should be suspected in every healthy young woman without cardiac risk factors, especially during the peripartum or postpartum periods. It is important to check for a history of drug abuse, collagen vascular disease or blunt trauma of the chest. Coronary angiography is essential for diagnosis and early management. We wonder whether thrombolysis might aggravate coronary dissection. All types of treatment (medical therapy, percutaneous intervention or surgery) improve the prognosis without affecting survival times if used appropriately according to the clinical stability and the angiographic features of the involved coronary arteries. Prompt recognition and targeted treatment improve outcomes. We report a case of SCAD in a young female free of traditional cardiovascular risk factors, who presented six hours after thrombolysis for ST elevation myocardial infarction. Coronary angiography showed a dissection of the left anterior descending and immediate branch. She had successful coronary artery bypass grafting, with complete healing of left anterior descending dissection.

    To identify the non-pharmacological risk factors for falling in older adults with type 2 diabetes mellitus (DM2). A systematic review of randomized controlled trials, prospective cohort studies, cross-sectional studies and before/after studies was conducted. Eligible studies identified non-pharmacological risk factors for falling in older adults with DM2. Medline, Embase, Pubmed and CINAHL were searched for relevant studies published through December 2015. Reference lists were also searched for relevant studies. Search terms were DM2, risk factors, falls and falling, older adults, aging, non-insulin dependent diabetes mellitus, accidental falls and trip. Publication language was restricted to English. Thirteen studies met the inclusion criteria: four cross-sectional, six prospective cohorts, two randomized controlled trials and one before/after study. These studies included a total of 13,104 participants, ≥50 years. The most common risk factors for falling were impaired balance, reduced walking velocity, peripheral neuropathy and comorbid conditions. However, lower extremity pain, being overweight and comorbid conditions had the greatest impact on fall risk. Interventions to reduce falling in older adults with type 2 diabetes mellitus should focus on reducing lower extremity pain, reducing body weight and managing comorbid conditions. Implications for Rehabilitation    Diabetes mellitus:   • Older adults with type 2 diabetes mellitus (DM2) have a higher risk for falling than older adults without.   • Older adults with DM2 are more likely to suffer serious injuries when they fall.   • Comprehensive risk factor identification is necessary for rehabilitation professionals to accurately determine whether their clients are at risk for falling.   • Rehabilitation professionals also need to tailor interventions based on the client's risk factors in order to effectively reduce falls and fall-related injuries.

    Spinal epidural abscess is an uncommon entity, the frequency of which is increasing. They occur spontaneously or as a complication of intervention. The classical triad of fever, back pain and neurological symptoms are not always present. High index of suspicion is key to diagnosis. Any delay in diagnosis and treatment can have significant neurological consequences. We present the case of a previously well man with a one month history of back pain resulting from an epidural abscess.

    To assess the prevalence of osteopenia and osteoporosis among Saudi postmenopausal women with non-insulin dependent type-2 diabetes mellitus (T2DM). The study was carried out at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from February 2000 to September 2002. bone mineral density (BMD) of lumbar spine and femoral neck using dual x-ray absorptionmetry (DXA; Lunar Wisconsin), were performed in 104 postmenopausal Saudi women with T2DM and 101postmenopausal non-diabetic women (control). Bone mineral density was measured in gm/cm and both T-score and Z-score were measured but only T-score ws used for analysis based on World Health Organization criteria. Bone profile, 25(OH) Vitamin D, 1.25(OH) Vitamin D, parathyroid harmone and urine deoxypyridinoline (DPD) were measured in both patients and controls. Body fit fat measurement aruond the biceps muscles using Futrex (body compostion analyzer) were performed in patients and controls. Years postmenopausal, duration of diabetes mellitus, parity, exercise, sun exposure and milk consumption were also recorded. In the diabetic group, the mean spine BMD was 0.928 gm/cm (T-score=2.28 SD) and for femoral neck the mean BMD was 0.817 gm/cm (T-score=-1.21SD). In control group, the mean spine BMD was 1.036 gm/cm (T-score=-1.2) and mean femoral neck BMD was 0.914 gm/cm (T-score=-0.608). In the diabetic group, there was 16(16.64%)patients with normal BMD of the spine, 42 patients (43.68%) with ostopenia (mean T-score=-1.8SD) and 45 (46.8%) with osteoporosis (mean T-score=-3.3 SD). Osteoporosis is most common among Type2 postmenopausal females in this ethnic group. Since both groups are postmenopausal, having equal percentage of Vitamin D deficiency, multi-parity, non exposure sun, lack of excercise and negligible milk intake, one can conlude that low BMD can be attributed to DM in the absence of other cause of osteoporosis.

    Full Text Available Spontaneously hypertriacylglycerolemic obese and diabetic inbred IIM Beta rats were treated with oleoyl- estrone for 10 days. Pair-feeding was performed to determine some oleoyl-estrone effects dependent on the caloric restriction it promotes. Twenty-five 200 day-old Beta males receiving a daily gavage of 0.2 ml sunflower oil were divided into the following groups: 1 daily dose of 10 nmol/g oleoyl-estrone; 2 pair-fed; 3 control. The variables measured were: whole body protein, water and lipid; retroperitoneal and epididymal fat depot weights; plasma urea, glucose, insulin, triacylglycerols and cholesterol. Biomass and food intake were assessed daily. Oleoyl-estrone and pair-fed groups expressed similar variations in body composition and significant body weight losses due to reduction in food intake. Oleoyl-estrone and pair-fed treatments significantly reduced retroperitoneal fat depot weights, but not epididymal ones. In oleoyl-estrone and pair-fed groups hyperglycemia decreased and insulinemia lowered significantly. Plasma normal total cholesterolemia and hypertriacylglycerolemia values typical of Beta rats decreased strongly compared to controls, though attaining significantly different values between oleoyl-estrone and pair-fed groups. Plasma total cholesterol appeared as more sensitive to caloric restriction than triacylglycerols through a specific oleoyl-estrone- mediated effect.Ratas endocriadas de la línea IIMBeta con obesidad, hipertriacilglicerolemia y diabetes espontáneas fueron tratadas con oleoil-estrona durante 10 días.

    Full Text Available O diabetes melito é considerada como uma síndrome que é, quanto a etiologia e patogênese, caracterizada por alterar a homeostase do organismo, por distúrbios metabólicos complexos e primários dos carboidratos, que envolvem secundariamente, porém de forma importante, lipídeos e proteínas. Grande número de espécies de plantas tem sido usado experimentalmente para tratar os sintomas do diabetes melito e a distância filogenética entre este grupo de plantas é forte indicação da natureza variada de seus constituintes. Tem sido constatado que muitas substâncias extraídas de plantas reduzem o nível de glicose no sangue. A grande diversidade de classes químicas indica que uma variedade de mecanismos de ação deve estar envolvida na redução do nível de glicose no sangue. Algumas destas substâncias podem ter potencial terapêutico enquanto outras podem produzir hipoglicemia como um efeito colateral devido à sua toxicidade, especialmente hepatotoxidade. Este artigo apresenta uma revisão atualizada e acrescenta mais plantas e princípios ativos hipoglicemiantes à extensa lista existente nos artigos de revisão anteriores.Diabetes mellitus comprises a group of ethiologically and clinically heterogeneous disorders with a common set of symptoms: excessive thirst and hunger, muscular weakness, weight loss, excessive urination and elevation of the blood glucose level among others. There has been a striking emergence of non-insulin-dependent diabetes mellitus as a major health problem in populations undergoing modernization of life-style, both in developed and underdeveloped nations. Many species of plants have been used ethnopharmacologically or experimentally to treat symptons of diabetes mellitus. The high percentage of active plants probably reflects, at least in part, the great variety of possible active constituents and mechanisms of action. The wide diversity of chemical classes indicate a variety of mechanisms must be involved

    Recently, two commercial enteral formulae for diabetic patients have been made available in Spain: a high-complex-carbohydrate, low-fat formulation (HCF) and a low-carbohydrate formulation (RCF). This study compares the effects of the two enteral nutritional formulae in patients with non-insulin-dependent diabetes mellitus (type 2 diabetes) treated with sulfonylurea or insulin. Fifty-two type 2 diabetes patients were randomly assigned to receive one of the two enteral formulae. Test enteral formula breakfast (250 cc) were consumed at approximately 0900 h after routine medications (insulin or oral agents) had been taken. Venous blood samples were obtained during fasting, before medication, and at 30 and 120 min after the start of the meal. The glycemic response of patients to the HCF was significantly greater than to RCF, but lower than in the sulfonyl type 2 diabetes treated groups. The incremental glucose response was within acceptable levels except in insulin treatment type 2 diabetes patients given HCF. Glucose, insulin, and C-peptide responses were higher in HCF than RCF groups. Two-factor analysis of variance on mean increments of blood glucose and C-peptide from basal levels to 30 min show the type of enteral nutrition as the main factor (P = 0.0010 and P = 0.0005, respectively). The RCF formula supplies 50.0% of energy as fat and 33.3% as carbohydrates, so it may be a ketogenic diet. It was found that both ketone bodies were higher after RCF than after HCF ingestion, but without statistical significance. We conclude that the partial replacement of complex digestible carbohydrates with monounsaturated fatty acids in the enteral formulae for supplementation of oral diet may improve glycemic control in patients with type 2 diabetes. The long-term effects of enteral diets high in monounsaturated fatty acids need further evaluation in patients with type 2 diabetes.

    Glutamic acid decarboxylase antibodies (GAD65Ab) are common in new onset Caucasian insulin-dependent diabetic (IDDM) patients but it is unclear if this marker is also prevalent in patients of other ethnic backgrounds. We determined antibodies against human recombinant GAD in Japanese diabetic patients using a radioimmunoassay with competition between in vitro translated 35S-GAD65 and non-labelled recombinant human GAD65 (rhGAD65). GAD67 antibodies (GAD67Ab) were similarly analyzed but without antigen competition. In 73 Japanese diabetic patients, GAD65Ab were found in 11/16 (69%) of patients with short-duration (less than 5 yrs) IDDM, 6/23 (26%) with long-duration (5 or more yrs) IDDM and 10/20 (50%) with slowly progressive diabetes. High GAD65Ab levels were associated with concomitant autoimmune diseases (p = 0.021). GAD67Ab were found in 4/16 (25%) of patients with short-duration IDDM, 3/23 (13%) with long-duration IDDM and 2/20 (10%) with slowly progressive diabetes. In 14 non-insulin dependent diabetic (NIDDM) patients, GAD65Ab and GAD67Ab were not found (0/14) and 1/50 (2%) healthy controls were positive in either assay. Among the GAD67Ab-positive samples, 8/9 (88%) were also high level GAD65Ab positive, 7/9 (77%) were displaced by an excess of rhGAD65 and the antibody levels correlated (r2 = 0.573; p = 0.003). Our data are consistent with a strong association of GAD65Ab also in Japanese IDDM, and suggest that, when present, GAD67Ab are frequently directed to epitope(s) common to GAD65 and GAD67.

    Twenty normal volunteers (C group) and 56 patients with non-insulin-dependent diabetes mellitus (NIDDM) who did not have ischemic heart diseases (DM group), were evaluated by means of iodine-123-metaiodobenzylguanidine (MIBG) scintigraphy. The uptake ratio between the cardiac muscle and the upper mediastinum was calculated. The ratio determined from the initial I-123-MIBG scintigraphy image was expressed as HMi, and that determined from the delayed image was expressed as HMd. The washout rate percentage (%WR) was calculated. At least one instance of either the HMi, the HMd, or %WR was outside the mean±1 standard deviation of C group in 34 DM group patients. Aldose reductase inhibitor (ARI) was administered to 17 of the 34 patients and Vitamin B 12 (VB 12 ) to the remaining 17 patients, for 3 to 5 months. Before and after treatment, scintigraphic studies with I-123-MIBG were carried out, and the HMi, HMd, and %WR were calculated. There were no significant differences found in FBG, HbA1c, or 1.5-AG levels after treatment with either drug, when compared to the pretreatment values. Both HMi and HMd in the DM group were significantly lower, and %WR was significantly higher than in the C group. The changes in HMi, HMd, and %WR after treatment with ARI were not significant. After treatment with VB 12 , the HMi and HMd levels were significantly increased (p 12 was shown to be effective for improvement of HMi and HMd in NIDDM. (author)

    Sildenafil citrate is a specific inhibitor of phosphodiesterase (PDE) type-5 and represents a powerful therapy for male erectile and fertility dysfunctions of different etiologies. Present study demonstrates whether sildenafil administration modifies seminal parameters in diabetic neuropathic patients. In this investigation 50 insulin dependent (IDDM) and 50 non insulin dependent (NIDDM) diabetic male patients with and without an objective evidence of neuropathy and 50 age matched non diabetic male controls were selected. Every male had age between 20 to 65 years with duration of diabetes distributed over 1 to 20 years. Treatment with 100 mg of oral sildenafil citrate on seminal parameters was evaluated by semen analysis in these patients. In both IDDM and NIDDM diabetic neuropathic patients, chronic sildenafil treatment exhibited a significant decrease in total sperm output and sperm concentration (p<0.001). On the other hand, sperm motility and semen volume were found to be increased by about 40% and 48% respectively in these patients, where as sperm morphology and quality of sperm motility remained unaffected. However both types of non neuropathic diabetics showed a non significant difference in all the above mentioned parameters when compared with the untreated groups and their respective control subjects. A comparison between IDDM and NIDDM neuropathic and non neuropathic diabetic groups further indicated a non significant difference in all the parameters of semen analysis. These findings suggest a chronic neuro physiological effect of sildenafil treatment on male fertility profile exclusively in diabetic neuropathic condition with an improvement in testicular function which was probably arrested due to some kind of testicular hyperplasia resulted by testicular necrosis and promoted spermatogenesis. Sildenafil seems to be associated with an improvement in the entire smooth musculature of reproductive tract and testicular morphology which was altered due to

Preliminary imaging delineated a haematoma in the anterior thigh, without any fractures or muscle trauma. Emergent fasciotomies were performed. No pathology could be identified intra-operatively, or on follow-up imaging. A review of thigh compartment syndromes described in literature is presented in a table. Emergency physicians and traumatologists should be cognisant of spontaneous atraumatic presentations of thigh compartment syndrome, to ensure prompt referral and definitive management of this limb-threatening condition.

    Full Text Available Tumor lysis syndrome (TLS is a known complication of malignancy and its treatment. The incidence varies on malignancy type, but is most common with hematologic neoplasms during cytotoxic treatment. Spontaneous TLS is thought to be rare. This case study is of a 62-year-old female admitted with multisystem organ failure, with subsequent diagnosis of aggressive B cell lymphoma. On admission, laboratory abnormalities included renal failure, elevated uric acid (20.7 mg/dL, and 3+ amorphous urates on urinalysis. Oliguric renal failure persisted despite aggressive hydration and diuretic use, requiring initiation of hemodialysis prior to chemotherapy. Antihyperuricemic therapy and hemodialysis were used to resolve hyperuricemia. However, due to multisystem organ dysfunction syndrome with extremely poor prognosis, the patient ultimately expired in the setting of a terminal ventilator wean. Although our patient did not meet current TLS criteria, she required hemodialysis due to uric acid nephropathy, a complication of TLS. This poses the clinical question of whether adequate diagnostic criteria exist for spontaneous TLS and if the lack of currently accepted guidelines has resulted in the underestimation of its incidence. Allopurinol and rasburicase are commonly used for prevention and treatment of TLS. Although both drugs decrease uric acid levels, allopurinol mechanistically prevents formation of the substrate rasburicase acts to solubilize. These drugs were administered together in our patient, although no established guidelines recommend combined use. This raises the clinical question of whether combined therapy is truly beneficial or, conversely, detrimental to patient outcomes.

    Epidural abscess is a rare complication of regional anesthesia, and spontaneous formation is even more uncommon. Diabetes mellitus, concomitant infection, intravenous drug use, and immune suppression are risk factors for spontaneous epidural abscess. A 29-year-old white woman presented at 28 weeks of estimated gestational age reporting an intermittent headache. She had Horner syndrome and was hospitalized. A cervicothoracic epidural abscess was diagnosed. Surgical decompression and parenteral antibiotics resulted in complete resolution of neurologic symptoms. Cultures were positive for methicillin-resistant Staphylococcus aureous. Spontaneous epidural abscess is a rare condition and diagnosis is often delayed. The finding of Horner syndrome led to imaging of the cervical spine and diagnosis of epidural abscess. Early intervention resulted in resolution of neurologic symptoms and a successful pregnancy outcome.

    Epidemiology is not only rare but an important cause of new daily persistent headaches among young & middle age individuals. The Etiology & Pathogenesis is generally caused by spinal CSF leak. Precise cause remains largely unknown, underlying structural weakness of spinal meninges is suspected. There are several MR Signs of Intracranial Hypotension that include:- diffuse pachymeningeal (dural) enhancement; bilateral subdural, effusion/hematomas; Downward displacement of brain; enlargement of pituitary gland; Engorgement of dural venous sinuses; prominence of spinal epidural venous plexus and Venous sinus thrombosis & isolated cortical vein thrombosis. The sum of volumes of intracranial blood, CSF & cerebral tissue must remain constant in an intact cranium. Treatment in Many cases can be resolved spontaneously or by use Conservative approach that include bed rest, oral hydration, caffeine intake and use of abdominal binder. Imaging Modalities for Detection of CSF leakage include CT myelography, Radioisotope cisternography, MR myelography, MR imaging and Intrathecal Gd-enhanced MR

    There are taken into account the main conceptual difficulties met by standard quantum mechanics in dealing with physical processes involving macroscopic system. It is stressed how J.A.Wheeler's remarks and lucid analysis have been relevant to pinpoint and to bring to its extreme consequences the puzzling aspects of quantum phenomena. It is shown how the recently proposed models of spontaneous dynamical reduction represent a consistent way to overcome the conceptual difficulties of the standard theory. Obviously, many nontrivial problems remain open, the first and more relevant one being that of generalizing the model theories considered to the relativistic case. This is the challenge of the dynamical reduction program. 43 refs, 2 figs

    non-insulin-dependent diabetes (type II. Methods: retrospective analysis of 57 pregestational diabetic woman charts who began a prenatal follow-up in the Service of Maternofetal Medicine of the Maternidade-Escola Assis Chateaubriand of the Universidade Federal do Ceará, in the period from January 1995 to December 1998. The 57 pregnant women included in the study were divided into groups: the first, composed of 28 patients with insulin-dependent diabetes (type I, and the second with 29 pregnant women with non-insulin-dependent diabetes (type II, controlled with diet or with oral hypoglycemics before pregnancy. Results: there was no statistically significant difference between the two groups in relation to the need of hospitalization for glycemia control (39.2% x 27.5% and maternal complications, such as: chronic arterial hypertension (14.2% x 27.5%, pregnancy-induced hypertension (14.2% x 17.2%, premature rupture of membranes (3.5% x 10.3%, urinary tract infection (10.7% x 6.8%, and preterm labor (3.5% x 6.8%. However, episodes of maternal hypoglycemia were more frequent among insulin-dependent patients (35.7% x 3.4%. The perinatal results were similar. We observed a great number of congenital anomalies and increased perinatal morbidity and mortality. Conclusion: there was no difference in the incidence of obstetric and clinical complications between insulin-dependent and non-insulin-dependent patients, except for maternal hypoglycemia.

    significant fat stranding. The image also showed an intraluminal stent traversing the gastric antrum and gastric pylorus with no indication of obstruction. Circumferential mural thickening of the gastric antrum and body were consistent with the patient’s history of gastric adenocarcinoma. The shotty perigastric lymph nodes with associated fat stranding, along the greater curvature of the distal gastric body suggested local regional nodal metastases and possible peritoneal carcinomatosis. The thoracic CT scans showed extensive pneumomediastinum that tracked into the soft tissues of the neck, which given the history of vomiting also raised concern for esophageal perforation. There was still no evidence of mediastinal abscess or fat stranding. Additionally, a left subclavian vein port catheter, which terminates with tip at the cavoatrial junction of the superior vena cava can also be seen on the image. Discussion: Spontaneous Pneumomediastinum, also known as Hamman syndrome, is defined by the uncommon incidence of free air in the mediastinum due to the bursting of alveoli, as a result of extended spells of shouting, coughing, or vomiting.1,2 The condition is diagnosed when a clear cause (aerodigestive rupture, barotrauma, infection secondary to gas-forming organisms3 for pneumomediastinum cannot be clearly identified on diagnostic studies. Macklin and Macklin were the first to note the pathogenesis of the syndrome and explained that the common denominator to spontaneous pneumomediastinum was that increased alveolar pressure leads to alveolar rupture.3 Common clinical findings for spontaneous pneumomediastinum include: chest pain, dyspnea, cough, and emesis.4 The condition is not always readily recognized on initial presentation in part for its rare incidence, estimated to be approximately 1 in every 44,500 ED patients3and also because of the non-specific presenting symptoms. For this patient, there was no clear singular cause, and therefore she received care for spontaneous

    To identify risk factors associated with spontaneous recurrent epistaxis. This was a retrospective cohort study assessing patients in the Marshfield Clinic system diagnosed as having epistaxis between January 1, 1991, and January 1, 2011. There were 461 cases with at least 2 episodes of spontaneous epistaxis within 3 years and 912 controls with only 1 episode in the same time frame. More than 50 potential risk factors were investigated, including demographic features, substance use, nasal anatomical abnormalities, nasal infectious and inflammatory processes, medical comorbidities, medications, and laboratory values. A Cox proportional hazards regression modeling approach was used to calculate hazard ratios of epistaxis recurrence. Traditional risk factors for epistaxis, including nasal perforation, nasal septum deviation, rhinitis, sinusitis, and upper respiratory tract infection, did not increase the risk of recurrence. Significant risk factors for recurrent epistaxis included congestive heart failure, diabetes mellitus, hypertension, and a history of anemia. Warfarin use increased the risk of recurrence, independent of international normalized ratio. Aspirin and clopidogrel were not found to increase the risk of recurrence. Few major adverse cardiovascular events were observed within 30 days of the first epistaxis event. Congestive heart failure is an underappreciated risk factor for recurrent epistaxis. Hypertension and diabetes mellitus may induce atherosclerotic changes in the nasal vessels, making them friable and more at risk for bleeding. Patients with recurrent epistaxis may also be more susceptible to developing anemia. Physicians should promote antiplatelet and antithrombotic medication adherence despite an increased propensity for recurrent epistaxis to prevent major adverse cardiovascular events.

  20. Analysis of the insulin receptor gene in noninsulin-dependent diabetes mellitus by denaturing gradient gel blots: A clinical research center study

    We have used a new technique of denaturing gradient gel blotting to determine the prevalence of alterations in the intracellular domain of the insulin receptor in normal individuals and subjects with non-insulin-dependent diabetes mellitus (NIDDM). This method detects DNA sequence differences as restriction fragment melting polymorphisms (RFMP) and is sensitive to changes in sequence at both restriction sites and within the fragments themselves. Using restriction digests with AluI, HaeIII, HinfI, RsaI, Sau3A, and Sau96, 12 RFMPs were found to localize to the region of the {beta}-subunit of the insulin receptor gene. Using exon-specific probes, these RFMPs could be localized to specific regions surrounding individual exons, including exons, 14, 15, 16, 18, 20, and 22. In general, linkage disequilibrium between polymorphisms was inversely related to their distance in the gene structure, although there was a {open_quotes}hot spot{close_quotes} for recombination between exons 19 and 20. No difference in melting temperatures or allele frequency was observed between NIDDM patients and controls. These data indicate that the region of the insulin receptor gene coding for the intracellular portion of the {beta}-subunit is highly polymorphic and that polymorphisms surrounding specific exons can be identified by denaturing gradient gel blotting, but there is no evidence that variation at this locus contributes to NIDDM susceptibility in most individuals. 36 refs., 3 figs., 3 tabs.

    Our objective was to identify transcriptional biomarkers in peripheral blood mononuclear cells (PBMC) that discriminate individuals with latent tuberculosis infection (LTBI) from those with pulmonary tuberculosis (PTB) in subjects with non-insulin-dependent diabetes mellitus (NIDDM) and in individuals without NIDDM. Using gene expression microarrays we identified differentially expressed genes from lungs of mice infected with Mycobacterium tuberculosis (Mtb) or a mutant (ΔsigH) representing a non-inflammatory model. Genes expressed in blood, with inflammatory related functions were evaluated in humans by RT-qPCR. NCF1 and ORM transcripts have the better discriminatory capacity to identify PTB subjects from LTBI and non-infected controls (NICs) independently of the presence of NIDDM. The sequential evaluation of the mRNA levels of NCF1 and ORM as multiple diagnostic tests showed 95% Sensitivity (Se) and 80% Specificity (Sp). In addition, FPR2 promises to be a good biomarker for the PTB detection in subjects with NIDDM (Se=100%; Sp=90%). Copyright © 2015 Elsevier Inc. All rights reserved.

  2. Spontaneous breaking of supersymmetry

    Energy Technology Data Exchange (ETDEWEB)

    Zumino, B.

    1981-12-01

    There has been recently a revival of interest in supersymmetric gauge theories, stimulated by the hope that supersymmetry might help in clarifying some of the questions which remain unanswered in the so called Grand Unified Theories and in particular the gauge hierarchy problem. In a Grand Unified Theory one has two widely different mass scales: the unification mass M approx. = 10/sup 15/GeV at which the unification group (e.g. SU(5)) breaks down to SU(3) x SU(2) x U(1) and the mass ..mu.. approx. = 100 GeV at which SU(2) x U(1) is broken down to the U(1) of electromagnetism. There is at present no theoretical understanding of the extreme smallness of the ratio ..mu../M of these two numbers. This is the gauge hierarchy problem. This lecture attempts to review the various mechanisms for spontaneous supersymmetry breaking in gauge theories. Most of the discussions are concerned with the tree approximation, but what is presently known about radiative correction is also reviewed.

    Spontaneous intracranial hypotension (SIH) is an uncommon but increasingly recognized syndrome. Orthostatic headache with typical findings on magnetic resonance imaging (MRI) are the key to diagnosis. Delayed diagnosis of this condition may subject patients to unnecessary procedures and prolong morbidity. We describe six patients with SIH and outline the important clinical and neuroimaging findings. They were all relatively young, 20-54 years old, with clearly orthostatic headache, minimal neurological signs (only abducent nerve paresis in two) and diffuse pachymeningeal gadolinium enhancement on brain MRI, while two of them presented subdural hygromas. Spinal MRI was helpful in detecting a cervical cerebrospinal fluid leak in three patients and dilatation of the vertebral venous plexus with extradural fluid collection in another. Conservative management resulted in rapid resolution of symptoms in five patients (10 days-3 weeks) and in one who developed cerebral venous sinus thrombosis, the condition resolved in 2 months. However, this rapid clinical improvement was not accompanied by an analogous regression of the brain MR findings that persisted on a longer follow-up. Along with recent literature data, our patients further point out that SIH, to be correctly diagnosed, necessitates increased alertness by the attending physician, in the evaluation of headaches

    2013-01-01

    A spontaneous encephalocele is one that develops either because of embryological maldevelopment or from a poorly understood postnatal process that permits brain herniation to occur. We here report a rare case of lateral temporal encephalocele extending to the infratemporal fossa under the zygomatic arch. At birth, the infant was noted to have a large cystic mass in the right side of the face. After being operated on initially in another center in the newborn period, the patient was referred to our clinic with a diagnosis of temporal encephalocele. He was 6 months old at the time of admission. Computerized tomography scan and magnetic resonance imaging studies revealed a 8 × 9 cm fluid-filled, multiloculated cystic mass at the right infratemporal fossa. No intracranial pathology or connection is seen. The patient was operated on to reduce the distortion effect of the growing mass. The histopathological examination of the sac revealed well-differentiated mature glial tissue stained with glial fibrillary acid protein. This rare clinical presentation of encephaloceles should be taken into consideration during the evaluation of the lateral facial masses in the infancy period, and possible intracranial connection should be ruled out before surgery to avoid complications.

    1. The anti-obesity and anti-diabetic effects of mazindol were evaluated in obese diabetic yellow KK mice and C57Bl control mice. 2. The study compound was fed through a gastric tube at a rate of 1 or 2 mg/kg per day (0.01 mol/L HCl as control) for 2 weeks. The following parameters were compared in treated and control animals: bodyweight, food intake, white adipose tissue (WAT) weight, brown adipose tissue (BAT) weight and its thermogenesis, noradrenaline (NA) turnover, blood glucose and serum insulin levels and glucose transporter 4 (GLUT4). 3. Furthermore, bodyweight loss of mice pair-fed the same amount of food as the mazindol-treated mice for 2 weeks was measured. 4. Mazindol significantly decreased food intake and significantly increased guanosine-5'-diphosphate-binding in BAT mitochondria and NA turnover in BAT in both yellow KK and C57Bl groups. The amounts of WAT in subcutaneous, mesenteric and retroperitoneal regions and bodyweights were significantly decreased in both groups. Bodyweight loss in mice pair fed with the mazindol-treated groups was approximately 70% compared with that in the mazindol-treated groups. Furthermore, mazindol decreased the levels of blood glucose and serum insulin during the glucose overloading test in yellow KK mice, but it did not influence the GLUT4 protein concentration in WAT and muscle. 5. These observations suggest that mazindol possesses both an anti-obesity action, due to the inhibition of appetite as well as the activation of BAT thermogenesis via increased NA turnover in BAT, and an anti-diabetic action. Consequently, mazindol may be useful for the treatment of obesity as well as non-insulin-dependent diabetes mellitus in obese persons.

  6. Bilateral spontaneous carotid artery dissection.

    2005-06-01

    Bilateral internal carotid artery dissections have been reported, but spontaneous bilateral dissections are rare. Internal carotid artery dissection can present with a spectrum of symptoms ranging from headache to completed stroke. Two cases of spontaneous bilateral carotid artery dissection are presented, one with headache and minimal symptoms and the other with a stroke syndrome. No cause could be found in either case, making the dissections completely spontaneous. Bilateral internal carotid artery dissection (ICAD) should be considered in young patients with unexplained head and neck pain with or without focal neurological symptoms and signs. The increasing availability of imaging would sustain the higher index of suspicion.

    Full Text Available La rata eSMT derivó del cruzamiento de eSS y b, líneas de la cepa IIM. eSS es un modelo de diabetes tipo 2 sin sobrepeso; b desarrolla obesidad moderada e intolerancia tardía a la glucosa. Fueron comparados características metabólicas y hallazgos histopatológicos del páncreas endocrino entre eSS y eSMT. Cotejados con eSS, los animales eSMT jóvenes son más corpulentos y desarrollan hiperglucemia de ayuno e intolerancia a la glucosa más precoces e intensas. En los machos eSMT de 6 y 9 meses existen islotes de formas alteradas y con fibrosis, detectándose esporádicas imágenes de apoptosis. En los de un año se tornan más pequeños y escasos, remedando la histoarquitectura de los machos eSS en el segundo año de vida; posteriormente los islotes van disgregándose, a la vez que muestran ocasionales mitosis y se observa nesidioblastosis. Se sugiere que estas modificaciones dinámicas constituyen una respuesta a la hiperglucemia. Las hembras eSS conservan por más tiempo la estructura insular y tienen menores alteraciones de la glucemia. El dimorfismo sexual del síndrome diabético de eSMT es atenuado respecto de eSS. La construcción de una tipología de individuos mediante el análisis multivariado separó tres clusters, evidenciando diferencias genéticas, etáreas y de sexo.The eSMT rat is derived from the crossing of eSS and b, both lines belonging to the IIM strain, while eSS is a model of type 2 diabetes without overweight and b develops moderate obesity and late glucose intolerance. Metabolic characteristics and histopathological findings in endocrine pancreas of eSS and eSMT were compared. Young eSMT animals are more robust than eSS and develop more intense fasting hyperglycemia and glucose intolerance at an earlier age. eSMT males of 6 and 9 months show islets with altered shapes and fibrosis, as well as sporadic images of apoptosis. At 12 months of age, islets are reduced in number and size, resembling the histoarchitecture of

It is poorly represented in the literature. Current evidence attributes it to orbital trauma, neoplasm, vascular malformations, acute sinusitis, and systemic abnormalities. A 65-year-old female presented with spontaneous intraorbital hematoma manifesting as severe ocular pains, eyelid edema, proptosis, and diplopia, without a history of trauma. Computer tomography demonstrated a fairly well defined extraconal lesion with opacification of the paranasal sinuses. The principal differential based on all findings was that of a spreading sinus infection and an extraconal tumor. An unprecedented finding of a spontaneous orbital hematoma was discovered when the patient was taken to theater. We discuss the rarity of this condition and its management.Keywords: hemorrhage, ophthalmology, spontaneous, intra-orbital, hematoma

    Glucagon like peptide-1 (GLP-1) receptor agonists such as exendin-4 have been widely used but their short half-life limits their therapeutic value. The recombinant protein, E2HSA, is a novel, long-acting GLP-1 receptor agonist generated by the fusion of exendin-4 with human serum albumin. In mouse pancreatic NIT-1 cells, E2HSA activated GLP-1 receptor with similar efficacy as exendin-4. After single-dose administration in ICR mice, E2HSA showed prolonged glucose lowering effects which lasted up to four days and extended inhibition on gastric emptying for at least 72 hours. Chronic E2HSA treatment in db/db mice significantly improved glucose tolerance, reduced elevated nonfasting and fasting plasma glucose levels, and also decreased HbA1c levels. E2HSA also increased insulin secretion and decreased body weight and appetite. Furthermore, immunofluorescence analysis showed that E2HSA increased β-cell area, improved islet morphology, and reduced β-cell apoptosis. In accordance with the promotion of β-cell function and survival, E2HSA upregulated genes such as Irs2, Pdx-1, Nkx6.1, and MafA and downregulated the expression levels of FoxO1 and proapoptotic Bcl-2 family proteins. In conclusion, with prolonged glucose lowering effects and promoting β-cell function and survival, the fusion protein, E2HSA, is a promising new therapeutic for once weekly treatment of type 2 diabetes.

    Fluorescein angiography was carried out see retinal vascular changes of the ocular fundus in 4 spontaneously occurring diabetic dogs. In all 4 cases, several hypofluorescent areas were determined to be filling defects of the retinal capillary bed of the tapetal fundi during the arteriovenous phase. Around these hypofluorescent areas, many dots of hyperfluorescence were also observed to be microaneurysms. However, no leaking of fluorescein was detected during angiography. These findings of 4 diabetic dogs were similar to those reported in man with non-proliferative diabetic retinopathy

    Most patients with type 2 (non-insulin-dependent) diabetes mellitus require pharmacotherapy, initially as monotherapy and subsequently in combination, as adjuncts to diet and exercise. Exogenous insulin is ultimately required in a substantial proportion, reflecting the progressive natural history of the disease. Sulphonylureas and biguanides have been employed for over 4 decades as oral antidiabetic agents, but they have a limited capacity to provide long term glycaemic control and can cause serious adverse effects. Thus, more efficacious and tolerable antidiabetic agents are required. Recent years have witnessed the introduction of agents with novel modes of action, that is, the alpha-glucosidase inhibitors acarbose and miglitol (which reduce postprandial hyperglycaemia) and the first of the thiazolidinedione insulinsensitising drugs--troglitazone and rosiglitazone. Although the former has been withdrawn in some countries due to adverse effects, another 'glitazone' pioglitazone is expected to be approved in the near future. Other recently introduced drugs include glimepiride and the meglitinide insulin secretagogue, repaglinide. Attention is also focusing increasingly on combination therapy using insulin together with sulphonylureas, metformin or troglitazone. Rapid-acting insulin analogues are now being used as alternatives to conventional insulins; their role in the management of type 2 diabetes mellitus is presently uncertain but reports of a reduced frequency of hypoglycaemia are encouraging. The development of new drugs aims to counter the principal metabolic defects of the disorder, respectively, relative insulin deficiency and insulin resistance. Novel classes of rapid-acting secretagogues under evaluation include the morphilinoguanide BTS 67582 and the meglitinides mitiglinide (KAD 1229) and senaglinide (A-4166). Succinate ester derivatives represent a potential novel approach to improving beta-cell function through enhancement of insulin biosynthesis and

    Metabolic syndrome (MetS) is a prevalent and complex disease, characterized by the variable coexistence of obesity, dyslipidemia, hyperinsulinaemia, and hypertension. The alarming rise in the prevalence of metabolic disorders makes it imperative to innovate preventive or therapeutic measures for MetS and its complications. However, the elucidation of the pathogenesis of MetS has been hampered by the lack of realistic models. For example, the existing animal models of MetS, i.e., genetically engineered rodents, imitate certain aspects of the disease, while lacking other important components. Defining the natural course of MetS in a spontaneous animal model of the disease would be desirable. Here, we introduce the Nile grass rat (NGR), Arvicanthis niloticus, as a novel model of MetS. Studies of over 1100 NGRs in captivity, fed normal chow, revealed that most of these animals spontaneously develop dyslipidemia (P<0.01), and hyperglycemia (P<0.01) by 1 yr of age. Further characterization showed that the diabetic rats develop liver steatosis, abdominal fat accumulation, nephropathy, atrophy of pancreatic islets of Langerhans, fatty streaks in the aorta, and hypertension (P<0.01). Diabetic NGRs in the early phase of the disease develop hyperinsulinemia, and show a strong inverse correlation between plasma adiponectin and HbA1c levels (P<0.01). These data indicate that the NGR is a valuable, spontaneous model for exploring the etiology and pathophysiology of MetS as well as its various complications.

    The authors thought it interesting to examine the interrelationship between nitric oxide and diabetes mellitus by the determination of the nitrite plasma levels, stable end-products of nitric oxide, in various clinical patterns of diabetes mellitus. Our series consisted of 161 female subjects (mean age 54 +/- 7 years, disease duration 5 +/- 3 months) subdivided into: a) 13 patients suffering from insulin-dependent diabetes (IDDM) without clinical and instrumental signs of micro- and macroangiopathy; b) 148 suffering from non insulin-dependent diabetes mellitus (NIDDM) of whom: 1) 52 without vascular complications (28 normal weight, BMI 30); 2) 40 with clinical and instrumental signs of non hypertensive coronary heart disease (CHD); 3) 25 with CHD and hypertension (arterial blood pressure over 160/95 mmHg); 4) 31 with hypercholesterolemia (values over 250 mg/dl). All patients were examined in good glycometabolic conditions reached by oral hypoglycemiant (12 cases) or insulin (149 cases) treatment. As normal control 37 female subjects (mean age 48 +/- 7) without internistic diseases were considered. For each sample we determined the plasma levels of nitrites by the Gutman and Hollywood method. Almost similar nitrite plasma levels in IDDM (17 +/- 0.5 mumol/L) and normal controls (17 +/- 0.2 mumol/L) were found; in non complicated non obese NIDDM a not significantly elevated value (21 +/- 0.8 mumol/L) as compared with the IDDM and control group was found; the obese NIDDM patients showed a value (18 +/- 0.4 mumol/L) not significantly different in comparison with the non obese NIDDM group. In the NIDDM group with non hypertensive CHD) the nitrite value was almost similar (20 +/- 0.5 mumol/L) to the corresponding group without vascular complications. In the patients with CHD and hypertension the nitrite level was superimposable (20 +/- 0.7 mumol/L) on the one recorded in NIDDM patients without vascular complications and in those with CHD without hypertension. In NIDDM

    We present two cases of transient central diabetes insipidus in preterm neonates with post-hemorrhagic hydrocephalus. Although the association between intraventricular hemorrhage and diabetes insipidus has been described in preterm infants, the association between diabetes insipidus and hydrocephalus, and the fact that such central diabetes insipidus could be reversible with the reduction of ventricular size, either because of spontaneous resolution or the placement of ventriculo-peritoneal shunt is first described here in neonates.

    Full Text Available The incidence of diabetic end-stage renal failure (ESRF varies worldwide and risk factors have been demonstrated in several populations. The objective of the present study was to identify possible factors associated with the risk of development of ESRF in patients with diabetes mellitus (DM. Two groups of diabetic subjects were included in a case-control study: 1 one group was submitted to renal replacement therapies, attending dialysis centers in São Paulo city and 2 the same number of controls without clinical nephropathy (two negative dipstick tests for urine protein, matched for duration of DM, were obtained from an outpatient clinic. A standardized questionnaire was used by a single investigator and additional data were obtained from the medical records of the patients. A total of 290 diabetic patients from 33 dialysis centers were identified, and 266 questionnaires were considered to contain reliable information. Male/female ratios were 1.13 for ESRF and 0.49 for the control group. A higher frequency of men was observed in the ESRF group when compared with controls (53 vs 33%, P<0.00001, although logistic regression analysis did not confirm an association of gender and diabetic nephropathy (DN. Similar proportions of non-white individuals were found for both groups. Patients with insulin-dependent diabetes mellitus (IDDM were less common than patients with non-insulin-dependent diabetes mellitus (NIDDM, particularly in the control group (3.4 vs 26.3%, P<0.00001, for controls and ESRF patients, respectively; this type of DM was associated with a higher risk of ESRF than NIDDM, as determined by univariate analysis or logistic regression (OR = 4.1. Hypertension by the time of the DM diagnosis conferred a 1.4-fold higher risk of ESRF (P = 0.04, but no difference was observed concerning the presence of a family history. Association between smoking and alcohol habits and increased risk was observed (OR = 4.5 and 5.9, respectively, P<0.001. A 2

    Full Text Available The recent and ongoing worldwide expansion in prevalence of Type 2 Diabetes (T2DM is a considerable risk to individuals, health systems and economies. The increase in prevalence has been particularly marked in the states of the Co-operation Council for the Arab States of the Gulf (GCC, and these trends are set to continue. We aimed to systematically review the current prevalence of T2DM within these states, and also within particular sub-populations.We identified 27 published studies for review. Studies were identified by systematic database searches. Medline and Embase were searched using terms such as diabetes mellitus, non-insulin-dependent, hyperglycemia, prevalence, epidemiology and Gulf States. Our search also included scanning reference lists, contacting experts and hand-searching key journals. Studies were judged against pre-determined inclusion and exclusion criteria, and where suitable for inclusion, data extraction and quality assessment was achieved using a specifically-designed tool. All studies where prevalence of diabetes was investigated were eligible for inclusion. The inclusion criteria required that the study population be of a GCC country, but otherwise all ages, sexes and ethnicities were included, resident and migrant populations, urban and rural, of all socioeconomic and educational backgrounds. No limitations on publication type, publication status, study design or language of publication were imposed. However, we did not include secondary reports of data, such as review articles without novel data synthesis.The prevalence of T2DM is an increasing problem for all GCC states. They may therefore benefit to a relatively high degree from co-ordinated implementation of broadly consistent management strategies. Further study of prevalence in children and in national versus expatriate populations would also be useful.

    This study composes of two parts. The first one is a survey of thyroid abnormalities, and the second one is experiment to estimate the level of thyroid hormones (T 4 , T 3 , TSH) among diabetic population and the relationship between the level of glucose, thyroid hormones and lipid profile (TC, LDL, TG, HDL) and comparison of the results with non diabetic group. The survey part of the study to determine the thyroid abnormalities, hypothyroidism or hyperthyroidism clinical or subclinical. Also the study group was divided in to two groups according to insulin requirement. Type I is insulin-dependent diabetes mellitus and type II is non insulin-dependent diabetes mellitus. The study subjects selected for this study consist of one hundred Sudanese diabetic patients, they had mean age of 46.51±10.672 years, a mean height of 162.06±10.77 cm and a mean weight of 73.47±14.91 kg. Fifty healthy non-diabetic people without endocrine disease were chosen as controls. Glucose, and thyroid hormones, thyroxine and triiodothyronine (total T 4 and T 3 ) 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

    The authors experienced a case of spontaneous ventriculocisternostomy diagnosed by CT scan with metrizamide and Conray. Patient was 23-year-old male who had been in good health until one month before admission, when he began to have headache and tinnitus. He noticed bilateral visual acuity was decreased about one week before admission and vomiting appeared two days before admission. He was admitted to our hospital because of bilateral papilledema and remarkable hydrocephalus diagnosed by CT scan. On admission, no abnormal neurological signs except for bilateral papilledema were noted. Immediately, right ventricular drainage was performed. Pressure of the ventricle was over 300mmH 2 O and CSF was clear. PVG and PEG disclosed an another cavity behind the third ventricle, which was communicated with the third ventricle, and occlusion of aqueduct of Sylvius. Metrizamide CT scan and Conray CT scan showed a communication between this cavity and quadrigeminal and supracerebellar cisterns. On these neuroradiological findings, the diagnosis of obstructive hydrocephalus due to benign aqueduct stenosis accompanied with spontaneous ventriculocisternostomy was obtained. Spontaneous ventriculocisternostomy was noticed to produce arrest of hydrocephalus, but with our case, spontaneous regression of such symptoms did not appeared. By surgical ventriculocisternostomy (method by Torkildsen, Dandy, or Scarff), arrest of hydrocephalus was seen in about 50 to 70 per cent, which was the same results as those of spontaneous ventriculocisternostomy. It is concluded that VP shunt or VA shunt is thought to be better treatment of obstructive hydrocephalus than the various kinds of surgical ventriculocisternostomy. (J.P.N.)

    Atoms and molecules are too small to act as efficient antennas for their own emission wavelengths. By providing an external optical antenna, the balance can be shifted; spontaneous emission could become faster than stimulated emission, which is handicapped by practically achievable pump intensities. In our experiments, InGaAsP nanorods emitting at ∼ 200 THz optical frequency show a spontaneous emission intensity enhancement of 35 × corresponding to a spontaneous emission rate speedup ∼ 115 ×, for antenna gap spacing, d = 40 nm. Classical antenna theory predicts ∼ 2,500 × spontaneous emission speedup at d ∼ 10 nm, proportional to 1/d(2). Unfortunately, at d antenna efficiency drops below 50%, owing to optical spreading resistance, exacerbated by the anomalous skin effect (electron surface collisions). Quantum dipole oscillations in the emitter excited state produce an optical ac equivalent circuit current, I(o) = qω|x(o)|/d, feeding the antenna-enhanced spontaneous emission, where q|x(o)| is the dipole matrix element. Despite the quantum-mechanical origin of the drive current, antenna theory makes no reference to the Purcell effect nor to local density of states models. Moreover, plasmonic effects are minor at 200 THz, producing only a small shift of antenna resonance frequency.

    Caffeic acid phenethyl ester (CAPE), extracted from propolis, was evaluated for the ameliorative effects on insulin resistance and the mechanisms were identified, using non-insulin-dependent diabetes mellitus (NIDDM) model mice and insulin resistance (IR) model cells. After 5 weeks of CAPE supplementation, insulin sensitivity, hyperlipidemia, and peroxisome proliferator-activated receptor-α (PPAR-α) levels were improved in mice. Proinflammatory cytokines in serum and the expressions of tumor necrosis factor-alpha (TNF-α) mRNA in tissues were markedly downregulated from CAPE-treated mice. In vitro, CAPE supplement significantly improved glucose consumption, glucose uptake, glycogen content, and oxidative stress and decreased expression of glucose-6-phosphatase (G6Pase) mRNA in cells. Both in vivo and in vitro, CAPE enhanced p-Akt (Ser473) and p-insulin receptor substrate (IRS)-1 (Tyr612), but inhibited p-JNK (Thr183/Tyr185), p-NF-κB p65 (Ser536), and nuclear translocation of p-NF-κB p65 (Ser536). In summary, CAPE can ameliorate insulin resistance through modulation of JNK and NF-κB signaling pathway in mice and HepG2 cells.

    To assess the role of CT in the etiologic diagnosis of spontaneous subcapsular and perirrenal hemorrhage. The CT findings are described in 13 patients presenting subcapsular and perirrenal hemorrhage. Those patients in whom the bleeding was not spontaneous were excluded. Surgical confirmation was obtained in nine cases. In 11 of the 13 cases (84.6%), involving five adenocarcinomas, five angiomyolipoma, two complicated cysts and one case of panarterities nodosa, CT disclosed the underlying pathology. In two cases (15.4%), it only revealed the extension of the hematoma, but gave no clue to its origin. CT is the technique of choice when spontaneous subcapsular and perirrenal hemorrhage is suspected since, in most cases, it reveals the underlying pathology. (Author)

    Full Text Available Dyspepsia with mild, stabbing epigastric discomfort without history of trauma is a very common symptom that emergency physicians see in their daily practice. Vascular emergencies, mostly the aortic dissection and aneurysm, are always described in the differential diagnosis with persistent symptoms. Isolated celiac artery dissection occurring spontaneously is a very rare diagnosis. The involvement of branch vessels is generally observed and patients show various clinical signs and symptoms according to the involved branch vessel. Here we are presenting a case with spontaneous isolated celiac artery dissection, without any branch vessel involvement or visceral damage, detected by computed tomography scans taken on admission.

    Mechanical oscillations are important for many cellular processes, e.g. the beating of cilia and flagella or the sensation of sound by hair cells. These dynamic states originate from spontaneous oscillations of molecular motors. A particularly clear example of such oscillations has been observed in muscle fibers under non-physiological conditions. In that case, motor oscillations lead to contraction waves along the fiber. By a macroscopic analysis of muscle fiber dynamics we find that the spontaneous waves involve non-hydrodynamic modes. A simple microscopic model of sarcomere dynamics highlights mechanical aspects of the motor dynamics and fits with the experimental observations.

    1994-01-01

    It is well known that spontaneous emission is not an intrinsic atomic property, but rather results from the coupling of the atom to the vacuum modes of the electromagnetic field. As such, it can be modified by tailoring the electromagnetic environment into which the atom can radiate. This was already realized by Purcell, who noted that the spontaneous emission rate can be enhanced if the atom placed inside a cavity is resonant with one of the cavity is resonant with one of the cavity modes, and by Kleppner, who discussed the opposite case of inhibited spontaneous emission. It has also been recognized that spontaneous emission need not be an irreversible process. Indeed, a system consisting of a single atom coupled to a single mode of the electromagnetic field undergoes a periodic exchange of excitation between the atom and the field. This periodic exchange remains dominant as long as the strength of the coupling between the atom and a cavity mode is itself dominant. 23 refs., 6 figs

    Identification of insulin resistance (IR) in the general population is important for developing strategies to reduce the prevalence of non-insulin-dependent diabetes mellitus (NIDDM). We used the original and a modified version of the Quantitative Insulin Sensitivity Check Index (QUICKI, M-QUICKI), and the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) to divide non-diabetic normotensive adults into high- (HIR) and low-insulin-resistant (LIR) subgroups to investigate similarities and differences in their characteristics. Three hundred fifty-seven healthy adults aged 18-50 years were recruited randomly from health centers in Jeddah in a cross-sectional study design. Anthropometric and demographic information was taken. Insulin, glucose, lipid profile and free fatty acid were determined in fasting blood samples. M-QUICKI, HOMA-IR and QUICKI were calculated. Reported cut-off points were used to identify HIR subjects, who were then matched for age and sex to others in the study population, resulting in 3 HIR and 3 LIR subgroups. Two hundred nine subjects satisfied the selection criteria. M-QUICKI correlated significantly (P=.01) with HOMA-IR and QUICKI values. Increased adiposity was the common characteristic of the three HIR subgroups. HIR subgroups identified using M-QUICKI (97 subjects) and HOMA (25 subjects), but not QUICKI (135 subjects), had statistically different biochemical characteristics compared to corresponding LIR sub-groups. Adiposity, but not sex, is a risk factor for IR in the studied population. Further studies are needed to choose the most appropriate index for detecting IR in community-based surveys.

    Dynamical and spontaneous positron emission are investigated for heavy-ion collisions with long time delay using a semiclassical description. Numerical results and analytical expressions for the characteristic quantities of the resulting spontaneous positron line, i.e., its position, width, and cross section, are compared. The expected behaviour of the line position and cross section and its visibility against the spectrum of dynamically created positrons is discussed in dependence of the united charge Zsub(u) of projectile and target nucleus in a range of systems from Zsub(u)=180 up to Zsub(u)=188. The results are confronted with presently available experimental data, and possible implications on further experiments are worked out. (orig.)

During what is known as the stagea IV growth phase, the fungus extends while rotating in a counterclockwise manner when viewed from above (stagea IVa) and then, while continuing to grow, spontaneously reverses to a clockwise rotation (stagea IVb). This phase lasts for 24-48Ah and is sometimes followed by yet another reversal (stageAIVc) before the overall growth ends. Here, we propose a continuum mechanical model of this entire process using nonlinear, anisotropic, elasticity and show how helical anisotropy associated with the cell wall structure can induce spontaneous rotation and, under appropriate circumstances, the observed reversal of rotational handedness. © 2011 American Physical Society.

    A case of spontaneous regression of transverse colon cancer is reported. A 64-year-old man was diagnosed as having cancer of the transverse colon at a local hospital. Initial and second colonoscopy examinations revealed a typical cancer of the transverse colon, which was diagnosed as moderately differentiated adenocarcinoma. The patient underwent right hemicolectomy 6 weeks after the initial colonoscopy. The resected specimen showed only a scar at the tumor site, and no cancerous tissue was proven histologically. The patient is alive with no evidence of recurrence 1 year after surgery. Although an antitumor immune response is the most likely explanation, the exact nature of the phenomenon was unclear. We describe this rare case and review the literature pertaining to spontaneous regression of colorectal cancer. © The Author 2014. Published by Oxford University Press. All rights reserved.

    Rudmik, Luke

    2012-01-01

    Background: Epistaxis is a common otolaryngology emergency and is often controlled with first-line interventions such as cautery, hemostatic agents, or anterior nasal packing. A subset of patients will continue to bleed and require more aggressive therapy. Methods: Intractable spontaneous epistaxis was traditionally managed with posterior nasal packing and prolonged hospital admission. In an effort to reduce patient morbidity and shorten hospital stay, surgical and endovascular techniques have gained popularity. A literature review was conducted. Results: Transnasal endoscopic sphenopalatine artery ligation and arterial embolization provide excellent control rates but the decision to choose one over the other can be challenging. The role of transnasal endoscopic anterior ethmoid artery ligation is unclear but may be considered in certain cases when bleeding localizes to the ethmoid region. Conclusion: This article will focus on the management of intractable spontaneous epistaxis and discuss the role of endoscopic arterial ligation and embolization as it pertains to this challenging clinical scenario.

    We discuss spontaneous baryogenesis in the warm inflation scenario. In contrast with standard inflation models, radiation always exists in the warm inflation scenario, and the inflaton must be directly coupled to it. Also, the transition to the post-inflationary radiation dominated phase is smooth and the entropy is not significantly increased at the end of the period of inflation. In addition, after the period of warm inflation ends, the inflaton does not oscillate coherently but slowly roll...

    Full Text Available Spontaneous rupture of spleen due to malignant melanoma is a rare situation, with only a few case reports in the literature. This study reports a previously healthy, 30-year-old man who came with chief complaint of acute abdominal pain to emergency room. On physical examination, abdominal tenderness and guarding were detected to be coincident with hypotension. Ultrasonography revealed mild splenomegaly with moderate free fluid in abdominopelvic cavity. Considering acute abdominal pain and hemodynamic instability, he underwent splenectomy with splenic rupture as the source of bleeding. Histologic examination showed diffuse infiltration by tumor. Immunohistochemical study (positive for S100, HMB45, and vimentin and negative for CK, CD10, CK20, CK7, CD30, LCA, EMA, and chromogranin confirmed metastatic malignant melanoma. On further questioning, there was a past history of a nasal dark skin lesion which was removed two years ago with no pathologic examination. Spontaneous (nontraumatic rupture of spleen is an uncommon situation and it happens very rarely due to neoplastic metastasis. Metastasis of malignant melanoma is one of the rare causes of the spontaneous rupture of spleen.

    Full Text Available Abstract As many as 50% of adults with type I (T1 diabetes exhibit bone loss and are at increased risk for fractures. Therapeutic development to prevent bone loss and/or restore lost bone in T1 diabetic patients requires knowledge of the molecular mechanisms accounting for the bone pathology. Because cell culture models alone cannot fully address the systemic/metabolic complexity of T1 diabetes, animal models are critical. A variety of models exist including spontaneous and pharmacologically induced T1 diabetic rodents. In this paper, we discuss the streptozotocin (STZ-induced T1 diabetic mouse model and examine dose-dependent effects on disease severity and bone. Five daily injections of either 40 or 60 mg/kg STZ induce bone pathologies similar to spontaneously diabetic mouse and rat models and to human T1 diabetic bone pathology. Specifically, bone volume, mineral apposition rate, and osteocalcin serum and tibia messenger RNA levels are decreased. In contrast, bone marrow adiposity and aP2 expression are increased with either dose. However, high-dose STZ caused a more rapid elevation of blood glucose levels and a greater magnitude of change in body mass, fat pad mass, and bone gene expression (osteocalcin, aP2. An increase in cathepsin K and in the ratio of RANKL/OPG was noted in high-dose STZ mice, suggesting the possibility that severe diabetes could increase osteoclast activity, something not seen with lower doses. This may contribute to some of the disparity between existing studies regarding the role of osteoclasts in diabetic bone pathology. Examination of kidney and liver toxicity indicate that the high STZ dose causes some liver inflammation. In summary, the multiple low-dose STZ mouse model exhibits a similar bone phenotype to spontaneous models, has low toxicity, and serves as a useful tool for examining mechanisms of T1 diabetic bone loss.

    Case, Daniel; Angilella, Jean-Regis; Motter, Adilson

    2017-11-01

    Precisely controlling flows within microfluidic systems is often difficult which typically results in systems being heavily reliant on numerous external pumps and computers. Here, I present a simple microfluidic network that exhibits flow rate switching, bistablity, and spontaneous oscillations controlled by a single pressure. That is, by solely changing the driving pressure, it is possible to switch between an oscillating and steady flow state. Such functionality does not rely on external hardware and may even serve as an on-chip memory or timing mechanism. I use an analytic model and rigorous fluid dynamics simulations to show these results.

    Arbuzova, Elena

    2017-04-01

    The classical version of spontaneous baryogenesis is studied in details. It is shown that the relation between the time derivative of the (pseudo)goldstone field and the baryonic chemical potential essentially depends upon the representation chosen for the fermionic fields with non-zero baryonic number (quarks). The kinetic equation, used for the calculations of the cosmological baryon asymmetry, is generalized to the case of non-stationary background. The effects of the finite interval of the integration over time are also included into consideration.

    Spontaneous osteonecrosis of the knee presents with acute onset of severe, pain in elderly patients, usually female and usually without a history of trauma. Originally described as idiopathic osteonecrosis, the exact etiology is still debated. Evidence suggests that an acute fracture occurs as a result of chronic stress or minor trauma to a weakened subchondral bone plate. The imaging characteristics on MR reflect the age of the lesion and the symptoms. More appropriate terminology may be ' subchondral insufficiency fracture of the knee' or 'focal subchondral osteonecrosis'.

  1. Radiological evaluation of spontaneous pneumoperitoneum

    1982-01-01

    112 cases of spontaneous penumoperitoneum, the causes of which were confirmed by clinical and surgical procedure at Presbyterian Medical Center from January, 1977 to July, 1981 were reviewed radiologically. The results were as follows: 1. Perforation of duodenal ulcer (46/112: 41.1%), stomach ulcer (22/112: 19.6%), and stomach cancer (11/112: 9.8%) were the three most common causes of spontaneous penumoperitoneum. These were 70.5% of all causes. 2. The most common site of free gas was both subdiaphragmatic areas (46: 41.1%). Others were Rt. subdiaphragmatic only (31: 27.7%), both subdiaphragmatic with subhepatic (16: 14.3%), Rt. subdiaphragmatic with subhepatic (7: 6.2%), Rt. subdiaphragmatic only (5: 4.4%), diffuse in abdomen (4: 3.6%), and subhepatic only (3: 2.7%). So 92.0% (103/112) were located in RUQ. 3. The radiological shape of free gas was classified: crescent (52: 46.4%) of small amount; half-moon (21: 18.8%) of moderate amount; large or diffuse (39: 34.8%) of large amount.4. The age between 31 and 60 occupied 69.1% (77/112), and male was predominant (5.2 times). 5. The patient's position showing free air most frequently was erect

  2. A Case of Multiple Spontaneous Keloid Scars

    Abdulhadi Jfri

    2015-07-01

    Full Text Available Keloid scars result from an abnormal healing response to cutaneous injury or inflammation that extends beyond the borders of the original wound. Spontaneous keloid scars forming in the absence of any previous trauma or surgical procedure are rare. Certain syndromes have been associated with this phenomenon, and few reports have discussed the evidence of single spontaneous keloid scar, which raises the question whether they are really spontaneous. Here, we present a 27-year-old mentally retarded single female with orbital hypertelorism, broad nasal bridge, repaired cleft lip and high-arched palate who presented with progressive multiple spontaneous keloid scars in different parts of her body which were confirmed histologically by the presence of typical keloidal collagen. This report supports the fact that keloid scars can appear spontaneously and are possibly linked to a genetic factor. Furthermore, it describes a new presentation of spontaneous keloid scars in the form of multiple large lesions in different sites of the body.

    2008-04-01

    This article provides an examination of issues related to spontaneity of communication in children with autism. Deficits relating to spontaneity or initiation are frequently reported in individuals with autism, particularly in relation to communication and social behavior. Nevertheless, spontaneity is not necessarily clearly conceptualized or measured. Several approaches to conceptualization of communicative spontaneity are examined with a particular focus on the continuum model and how it might be practically applied. A range of possible explanations for deficits in spontaneity of communication in children with autism is subsequently explored, including external factors (highly structured teaching programs, failure to systematically instruct for spontaneity) and intrinsic characteristics (intellectual disability, stimulus overselectivity, weak central coherence). Possible implications for future research are presented.

    Full Text Available Spontaneous bacterial peritonitis is a common complication in patients with cirrhosis and ascites. However, spontaneous peritonitis caused by Cryptococcus neoformans is uncommon. Delayed diagnosis of cryptococcal peritonitis often results in death. We describe three cases of spontaneous cryptococcal peritonitis in patients with decompensated cirrhosis. One case had associated symptomatic human immunodeficiency virus infection. Clinical awareness of this entity may lead to the early diagnosis and proper treatment.

    Spontaneous pararenal hematoma is a rare pathology most frequently coexisting with renal tumours, vascular anomalies and inflammatory processes. In some cases one cannot establish its etiology. The paper describes a case of a 58-year-old man with a spontaneous pararenal hematoma and presents a diagnostic algorithm. Ultrasonography and CT play an important role in diagnostics of spontaneous pararenal haemorrhages. These methods enable a precise evaluation of size and location of hematoma and its evolution.

    Recent evidence has indicated that total fiber intake is inversely related to type 2 diabetes risk. The present study aimed to investigate the effects of chronic administration of partially hydrolyzed guar gum (PHGG), a water-soluble dietary fiber, on the occurrence of diabetes and its complications, fatty liver and nephropathy. We also identified predictive serum biomarkers of treatment response to PHGG by mass spectroscopy-based proteomic analysis using Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a good model of human non-insulin-dependent diabetes mellitus. In this study, at 5 weeks of age, OLETF rats and control strain Long-Evans Tokushima Otsuka (LETO) rats were fed a control diet or a high-fiber diet (5% PHGG) for 57 weeks. Body weight, food intake, oral glucose tolerance test, plasma insulin levels, and urine glucose and protein levels were regularly measured. Oral glucose tolerance tests (OGTT) and storage of serum in a deep freezer were conducted at the beginning of the experiment and every 4 weeks after overnight fasting during the experiments. PHGG treatment affected neither meal patterns nor the body weight of OLETF and LETO rats. Repeated measure analysis of variance revealed significant differences in fasting plasma glucose and plasma glucose at 2 h after OGTT between control OLETF (OLETF-C) rats and OLETF rats treated with PHGG (OLETF-F). The glucose response determined by the area under the curve of OGTT was significantly greater in OLETF-C rats than that in OLETF-F rats at 25 weeks of age. HOMA-IR, an index of insulin resistance, increased at 25 weeks of age in OLETF-C rats, while this increase was significantly inhibited in OLETF-F rats. At 62 weeks of age, PHGG treatment significantly improved hepatic steatosis as well as renal mesangial matrix accumulation in OLETF rats. To identify the risk marker for diabetes mellitus by SELDI-TOF MS, we collected sera from 21-week-old individuals. Among the 12 specific peaks that were risk marker

  11. Recurrent spontaneous attacks of dizziness.

    Science.gov (United States)

    Lempert, Thomas

    2012-10-01

    This article describes the common causes of recurrent vertigo and dizziness that can be diagnosed largely on the basis of history. Ninety percent of spontaneous recurrent vertigo and dizziness can be explained by six disorders: (1) Ménière disease is characterized by vertigo attacks, lasting 20 minutes to several hours, with concomitant hearing loss, tinnitus, and aural fullness. Aural symptoms become permanent during the course of the disease. (2) Attacks of vestibular migraine may last anywhere from minutes to days. Most patients have a previous history of migraine headaches, and many experience migraine symptoms during the attack. (3) Vertebrobasilar TIAs affect older adults with vascular risk factors. Most attacks last less than 1 hour and are accompanied by other symptoms from the posterior circulation territory. (4) Vestibular paroxysmia is caused by vascular compression of the eighth cranial nerve. It manifests itself with brief attacks of vertigo that recur many times per day, sometimes with concomitant cochlear symptoms. (5) Orthostatic hypotension causes brief episodes of dizziness lasting seconds to a few minutes after standing up and is relieved by sitting or lying down. In older adults, it may be accompanied by supine hypertension. (6) Panic attacks usually last minutes, occur in specific situations, and are accompanied by choking, palpitations, tremor, heat, and anxiety. Less common causes of spontaneous recurrent vertigo and dizziness include perilymph fistula, superior canal dehiscence, autoimmune inner ear disease, otosclerosis, cardiac arrhythmia, and medication side effects. Neurologists need to venture into otolaryngology, internal medicine, and psychiatry to master the differential diagnosis of recurrent dizziness.

  12. Crows spontaneously exhibit analogical reasoning.

    Smirnova, Anna; Zorina, Zoya; Obozova, Tanya; Wasserman, Edward

    2015-01-19

    Analogical reasoning is vital to advanced cognition and behavioral adaptation. Many theorists deem analogical thinking to be uniquely human and to be foundational to categorization, creative problem solving, and scientific discovery. Comparative psychologists have long been interested in the species generality of analogical reasoning, but they initially found it difficult to obtain empirical support for such thinking in nonhuman animals (for pioneering efforts, see [2, 3]). Researchers have since mustered considerable evidence and argument that relational matching-to-sample (RMTS) effectively captures the essence of analogy, in which the relevant logical arguments are presented visually. In RMTS, choice of test pair BB would be correct if the sample pair were AA, whereas choice of test pair EF would be correct if the sample pair were CD. Critically, no items in the correct test pair physically match items in the sample pair, thus demanding that only relational sameness or differentness is available to support accurate choice responding. Initial evidence suggested that only humans and apes can successfully learn RMTS with pairs of sample and test items; however, monkeys have subsequently done so. Here, we report that crows too exhibit relational matching behavior. Even more importantly, crows spontaneously display relational responding without ever having been trained on RMTS; they had only been trained on identity matching-to-sample (IMTS). Such robust and uninstructed relational matching behavior represents the most convincing evidence yet of analogical reasoning in a nonprimate species, as apes alone have spontaneously exhibited RMTS behavior after only IMTS training.

    BACKGROUND: Spontaneous abortion is the most commonly observed adverse pregnancy outcome. The angiogenic factors soluble Fms-like kinase 1 and placental growth factor are critical for normal pregnancy and may be associated to spontaneous abortion. OBJECTIVE: We investigated the association between...... maternal serum concentrations of soluble Fms-like kinase 1 and placental growth factor, and subsequent spontaneous abortion. STUDY DESIGN: In the prospective observational Odense Child Cohort, 1676 pregnant women donated serum in early pregnancy, gestational week ..., interquartile range 71-103). Concentrations of soluble Fms-like kinase 1 and placental growth factor were determined with novel automated assays. Spontaneous abortion was defined as complete or incomplete spontaneous abortion, missed abortion, or blighted ovum

  6. The (perceived) meaning of spontaneous thoughts.

    Spontaneous thoughts, the output of a broad category of uncontrolled and inaccessible higher order mental processes, arise frequently in everyday life. The seeming randomness by which spontaneous thoughts arise might give people good reason to dismiss them as meaningless. We suggest that it is precisely the lack of control over and access to the processes by which they arise that leads people to perceive spontaneous thoughts as revealing meaningful self-insight. Consequently, spontaneous thoughts potently influence judgment. A series of experiments provides evidence supporting two hypotheses. First, we hypothesize that the more a thought is perceived to be spontaneous, the more it is perceived to provide meaningful self-insight. Participants perceived more spontaneous kinds of thought (e.g., intuition) to reveal greater self-insight than did more controlled kinds of thought in Study 1 (e.g., deliberation). In Studies 2 and 3, participants perceived thoughts with the same content and target to reveal greater self-insight when spontaneously rather than deliberately generated (i.e., childhood memories and impressions formed). Second, we hypothesize that the greater self-insight attributed to thoughts that are (perceived to be) spontaneous leads those thoughts to more potently influence judgment. Participants felt more sexually attracted to an attractive person whom they thought of spontaneously than deliberately in Study 4, and reported their commitment to a current romantic relationship would be more affected by the spontaneous rather than deliberate recollection of a good or bad experience with their romantic partner in Study 5.

    This study aimed to assess the relationship between the cerebro-placental ratio (CPR) and intrapartum and perinatal outcomes in pregnancies complicated by pre-existing insulin dependent diabetes (pT1DM) mellitus, pre-existing non-insulin dependent diabetes mellitus (pT2DM) and gestational diabetes mellitus (GDM). This was a retrospective cohort study of 1281 women with diabetes mellitus birthing at the Mater Mothers' Hospital in Brisbane between 2007 and 2015. The CPR in non-anomalous singleton fetuses was measured between 34+0 and 36+6 weeks gestation and compared between types of DM treatment groups and correlated with intrapartum and perinatal outcomes. Of the study cohort, 9.7% (124/1281) had pT1DM, 5.3% (68/1281) had pT2DM and 85.0% (1089/1281) had GDM. Of women with pT2DM and GDM, 61.8% (42/68) and 28.9% (315/1089) respectively, required insulin during pregnancy. Women with pT1DM had an increased odds of having a CPR 90th centile (OR 2.69, 95% CI: 1.60-4.39, p=0.0001) was higher in the pT1DM cohort. There was however no significant difference in the mean MCA PI between the three groups. Stratification by CPR centiles (<10th centile vs. ≥10th centile) demonstrated a lower birth weight in the CPR <10th centile cohort for all DM categories. The proportion of neonates with birth weights <10th centile were higher in the CPR <10th centile cohort with the GDM cohort having an odds ratio of 8.28 (95% CI 4.22-16.13, p<0.0001) of this complication. The CPR <10th centile cohort also had a greater proportion of adverse composite neonatal outcome regardless of type of DM. Regardless of the type of DM, a low CPR was associated with poorer neonatal outcomes. Women with pT1DM also had the highest mean UA PI and lowest mean CPR despite no difference in the mean MCA PI between the three groups. Copyright © 2017 Elsevier B.V. All rights reserved.

  11. Alteration of the Cardiac Sympathetic Innervation Is Modulated by Duration of Diabetes in Female Rats

    2011-01-01

    Full Text Available To evaluate the sympathetic innervation of the female diabetic heart, resting heart rate and sympathetic tone were assessed in vivo, and effect of tyramine on spontaneous beating rate, norepinephrine atrial concentrations, uptake, and release were determined in vitro in streptozotocin- (STZ- treated rats and respective controls aged 3 months to 2 years. Resting bradycardia, decreased sympathetic tone, deceleration of spontaneous beating rate, and slightly declining carrier-mediated, but preserved exocytotic norepinephrine release from the atria were found in younger diabetic rats while the reactivity of the right atria to tyramine was not affected with age and disease duration. Diabetic two-year-old animals displayed symptoms of partial spontaneous recovery including normoglycemia, increased plasma insulin concentrations, fully recovered sympathetic tone, but putative change, in releasable norepinephrine tissue stores. Our data suggested that female diabetic heart exposed to long-lasting diabetic conditions seems to be more resistant to alteration in sympathetic innervation than the male one.

    Full Text Available The sensitivity of adult spontaneously hypertensive rats (SHR to the diabetogenic effect of streptozotocin (STZ was studied. The animals were subdivided into three groups: control (citrate buffer, streptozotocin 40 mg/kg or 50 mg/kg, and general biologic parameters were analyzed, in addition to systolic blood pressure, blood glucose and insulin levels determinations. Both doses were able to induce hyperglycemia above 300 mg/dl; however, 50 mg/kg provoked a more pronounced physiological alterations in body weight, diuresis, water and food intake. There was no change on systolic blood pressure with either dose. Results suggested that SHRs did not need doses of streptozotocin above 40mg/kg in order to produce diabetes probably because this strain was much more sensible than normotensive rats. In addition, streptozotocin might be a drug choice to induce diabetes without provoking alterations in the blood pressure which allowed the use of this experimental model in the studies of induced hypertension-diabetes.Foi estudada a sensibilidade de ratos espontaneamente hipertensos (SHR adultos ao efeito diabetogênico da estreptozotocina (STZ. Os animais foram subdivididos em grupos: controle (tampão citrato, 40 mg/kg ou 50 mg/kg de estreptozotocina, sendo analisados parâmetros biológicos gerais, pressão arterial sistólica, níveis sanguíneos de glicose e insulina. Ambas doses foram capazes de induzir hiperglicemia acima de 300 mg/dl, entretanto a dose de 50 mg/kg provocou efeitos fisiológicos mais pronunciados no peso corpóreo, diurese, ingestão hídrica e de ração. Não houve alteração da pressão arterial sistólica em qualquer dose. Nossos achados sugerem que SHRs não necessitam de doses de estreptozotocina acima de 40 mg/kg com para produzir diabetes, provavelmente porque essa cepa é muito mais sensível do que ratos normotensos. A estreptozotocina pode ser a droga de escolha para induzir diabetes sem provocar alterações na press

  14. Spontaneous Metacognition in Rhesus Monkeys.

    Rosati, Alexandra G; Santos, Laurie R

    2016-09-01

    Metacognition is the ability to think about thinking. Although monitoring and controlling one's knowledge is a key feature of human cognition, its evolutionary origins are debated. In the current study, we examined whether rhesus monkeys (Macaca mulatta; N = 120) could make metacognitive inferences in a one-shot decision. Each monkey experienced one of four conditions, observing a human appearing to hide a food reward in an apparatus consisting of either one or two tubes. The monkeys tended to search the correct location when they observed this baiting event, but engaged in information seeking-by peering into a center location where they could check both potential hiding spots-if their view had been occluded and information seeking was possible. The monkeys only occasionally approached the center when information seeking was not possible. These results show that monkeys spontaneously use information about their own knowledge states to solve naturalistic foraging problems, and thus provide the first evidence that nonhumans exhibit information-seeking responses in situations with which they have no prior experience. © The Author(s) 2016.

    2013-01-01

    Flocking behaviour, as a type of self-organised collective behaviour, is described as the spatial formation of groups without global control and explicit inter-individual recruitment signals. It can be observed in many animals, such as bird flocks, shoals or herds of ungulates. Spatial attraction between humans as the central component of flocking behaviour has been simulated in a number of seminal models but it has not been detected experimentally in human groups so far. The two other sub-processes of this self-organised collective movement - collision avoidance and alignment - are excluded or held constant respectively in this study. We created a computer-based, multi-agent game where human players, represented as black dots, moved on a virtual playground. The participants were deprived of social cues about each other and could neither communicate verbally nor nonverbally. They played two games: (1) Single Game, where other players were invisible, and (2) Joint Game, where each player could see players' positions in a local radius around himself/herself. We found that individuals approached their neighbours spontaneously if their positions were visible, leading to less spatial dispersion of the whole group compared to moving alone. We conclude that human groups show the basic component of flocking behaviour without being explicitly instructed or rewarded to do so. Copyright © 2012 Elsevier B.V. All rights reserved.

  16. Simultaneous bilateral primary spontaneous pneumothorax

    2014-04-01

    Full Text Available Simultaneous bilateral primary pneumothorax is a very rare (1.6 / 100,000 and life-threatening condition. Clinical presentation may vary from mild dyspnea to tension pneumothorax. It may be milder particularly in younger patients, but more severe in patients with advanced age, and tube thoracostomy is a life preserver in the latter group. Since mortality and recurrence rates following tube thoracostomy are high, endoscopic approaches to bilateral hemithorax have been reported in literature. Apical wedge resection and pleural procedures are recommended in video thoracoscopy or mini thoracotomy even if no bulla and/or bleb are detected. Bilateral surgical interventions and additional pleural procedures are associated with increased rate of post-operative complications and longer postoperative hospital-stays. As a first-line approach, the surgical method toward any side of lung with air leakage following a previous tube thoracostomy is considered less invasive, especially in younger patients. Here, we present a case of simultaneous bilateral primary spontaneous pneumothorax (SBPSP in a 21-year old male with no history of smoking and chronic pulmonary disease. A unilateral surgical intervention was performed, and no recurrence was observed during 5-year follow up.

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    The literature shows a variable and inconsistent relationship between socioeconomic position and preterm birth. We examined risk factors for spontaneous and iatrogenic preterm birth, with a focus on socioeconomic position and clinical risk factors, in order to explain the observed inconsistency. We carried out a retrospective population-based cohort study of all singleton deliveries in Nova Scotia from 1988 to 2003. Data were obtained from the Nova Scotia Atlee Perinatal Database and the federal income tax T1 Family Files. Separate logistic models were used to quantify the association between socioeconomic position, clinical risk factors and spontaneous preterm birth and iatrogenic preterm birth. The study population included 132,714 singleton deliveries and the rate of preterm birth was 5.5%. Preterm birth rates were significantly higher among the women in the lowest (versus the highest) family income group for spontaneous (rate ratio 1.14, 95% confidence interval (CI) 1.03, 1.25) but not iatrogenic preterm birth (rate ratio 0.95, 95% CI 0.75, 1.19). Adjustment for maternal characteristics attenuated the family income-spontaneous preterm birth relationship but strengthened the relationship with iatrogenic preterm birth. Clinical risk factors such as hypertension were differentially associated with spontaneous (rate ratio 3.92, 95% CI 3.47, 4.44) and iatrogenic preterm (rate ratio 14.1, 95% CI 11.4, 17.4) but factors such as diabetes mellitus were not (rate ratio 4.38, 95% CI 3.21, 5.99 for spontaneous and 4.02, 95% CI 2.07, 7.80 for iatrogenic preterm birth). Socioeconomic position and clinical risk factors have different effects on spontaneous and iatrogenic preterm. Recent temporal increases in iatrogenic preterm birth appear to be responsible for the inconsistent relationship between socioeconomic position and preterm birth.

    Diabetic retinopathy (DR) is a common complication of diabetes mellitus and is a major cause of vision loss in middle-aged and elderly people. One-third of people with diabetes have DR. Severe stages of DR include proliferative DR, caused by the abnormal growth of new retinal blood vessels......, and diabetic macular oedema, in which there is exudation and oedema in the central part of the retina. DR is strongly associated with a prolonged duration of diabetes, hyperglycaemia and hypertension. It is traditionally regarded as a microvascular disease, but retinal neurodegeneration is also involved...... (VEGF). Optimal control of blood glucose and blood pressure in individuals with diabetes remains the cornerstone for preventing the development and arresting the progression of DR. Anti-VEGF therapy is currently indicated for diabetic macular oedema associated with vision loss, whereas laser...

    We investigate the quantum dynamics of a driven two-level system under spontaneous emission and its application in clock frequency estimation. By using the Lindblad equation to describe the system, we analytically obtain its exact solutions, which show three different regimes: Rabi oscillation, damped oscillation, and overdamped decay. From the analytical solutions, we explore how the spontaneous emission affects the clock frequency estimation. We find that under a moderate spontaneous emission rate, the transition frequency can still be inferred from the Rabi oscillation. Our results enable potential practical applications in frequency measurement and quantum control under decoherence.

    Although there are many reports of spontaneous regression of noninvasive thymoma, there are no reports of spontaneous regression of an invasive thymoma. Moreover, the mechanism of the spontaneous regression is still unknown. The present case concerns a 47-year-old man who presented with chest pain. Computed tomography (CT) showed a large anterior mediastinal mass with left pleural effusion that occluded the innominate vein. The tissue obtained by video-assisted thoracic surgery suggested a diagnosis of invasive thymic carcinoma. One month later CT showed prominent regression of the tumor, and the tumor was completely resected. On pathology, the diagnosis was thymoma type B3.

    Spontaneous dissection of the superior mesenteric artery (SMA) is a rare occurrence, especially when not associated with aortic dissection. Currently, only 28 cases appear to have been reported. Due to the scarcity of cases in the literature, the natural history of isolated, spontaneous SMA dissection is unclear. CT has been reported to be useful for the initial diagnosis of SMA dissection [2-5]. We present two recent cases of spontaneous SMA dissection in which enhanced spiral CT was instrumental in following the disease process and guiding clinical decision making

    Souchon, Nicolas; Maio, Gregory R; Hanel, Paul H P; Bardin, Brigitte

    2017-10-01

    We conducted five studies testing whether an implicit measure of favorability toward power over universalism values predicts spontaneous prejudice and discrimination. Studies 1 (N = 192) and 2 (N = 86) examined correlations between spontaneous favorability toward power (vs. universalism) values, achievement (vs. benevolence) values, and a spontaneous measure of prejudice toward ethnic minorities. Study 3 (N = 159) tested whether conditioning participants to associate power values with positive adjectives and universalism values with negative adjectives (or inversely) affects spontaneous prejudice. Study 4 (N = 95) tested whether decision bias toward female handball players could be predicted by spontaneous attitude toward power (vs. universalism) values. Study 5 (N = 123) examined correlations between spontaneous attitude toward power (vs. universalism) values, spontaneous importance toward power (vs. universalism) values, and spontaneous prejudice toward Black African people. Spontaneous positivity toward power (vs. universalism) values was associated with spontaneous negativity toward minorities and predicted gender bias in a decision task, whereas the explicit measures did not. These results indicate that the implicit assessment of evaluative responses attached to human values helps to model value-attitude-behavior relations. © 2016 The Authors.

    2017-01-01

    The present research investigates whether spontaneous trait inferences occur under conditions characteristic of social media and networking sites: nonextreme, ostensibly self-generated content, simultaneous presentation of multiple cues, and self-paced browsing. We used an established measure of trait inferences (false recognition paradigm) and a direct assessment of impressions. Without being asked to do so, participants spontaneously formed impressions of people whose status updates they saw. Our results suggest that trait inferences occurred from nonextreme self-generated content, which is commonly found in social media updates (Experiment 1) and when nine status updates from different people were presented in parallel (Experiment 2). Although inferences did occur during free browsing, the results suggest that participants did not necessarily associate the traits with the corresponding status update authors (Experiment 3). Overall, the findings suggest that spontaneous trait inferences occur on social media. We discuss implications for online communication and research on spontaneous trait inferences.

    Abortion is associated with moderate to high risk of psychological problems such as depression, use of alcohol or marijuana, anxiety, depression and suicidal behaviours. The increased risk of depression after spontaneous abortion in Asian populations has not been clearly established. Only a few studies have explored the relationship between grief and depression after abortion. A study was conducted to assess the prevalence and risk factors of depressive disorder and complicated grief among women 6-10 weeks after spontaneous abortion and compare the risk of depression with pregnant women attending an antenatal clinic. Spontaneous abortion group consisted of women diagnosed with spontaneous abortion by a Consultant Obstetrician. Women with confirmed or suspected induced abortion were excluded. The comparison group consisted of randomly selected pregnant, females attending the antenatal clinics of the two hospitals. Diagnosis of depressive disorder was made according to ICD-10 clinical criteria based on a structured clinical interview. This assessment was conducted in both groups. The severity of depressive symptoms were assessed using the Patients Health Questionnaire (PHQ-9). Grief was assessed using the Perinatal Grief Scale which was administered to the women who had experienced spontaneous abortion. The sample consisted of 137 women in each group. The spontaneous abortion group (mean age 30.39 years (SD = 6.38) were significantly older than the comparison group (mean age 28.79 years (SD = 6.26)). There were more females with ≥10 years of education in the spontaneous abortion group (n = 54; SD = 39.4) compared to the comparison group (n = 37; SD = 27.0). The prevalence of depression in the spontaneous abortion group was 18.6 % (95 CI, 11.51-25.77). The prevalence of depression in the comparison group was 9.5 % (95 CI, 4.52-14.46). Of the 64 women fulfilling criteria for grief, 17 (26.6 %) also fulfilled criteria for a depressive episode. The relative risk of

    Spontaneous uterine rupture and generalized peritonitis caused by pyometra occurs rarely with high morbidity and mortality. A correct and definite diagnosis can be made with laparotomy or laparoscopy. The clinical findings of perforated pyometra are similar to perforation of the gastrointestinal tract and gynecologic symptoms are less frequent, which makes preoperative diagnosis difficult. We report a case of a patient aged 82 years who underwent surgery for spontaneous uterine rupture and generalized peritonitis as a result of pyometra. PMID:28913055

    Non-traumatic, spontaneous diaphragmatic rupture is a rare event whose pathophysiology is not known. We report the case of endometriosis-related spontaneous rupture of the right diaphragm with intrathoracic herniation of the liver, gallbladder and colon. We hypothesize that the invasiveness of endometriotic tissue caused diaphragm fragility, which finally lead to its complete rupture without traumatic event. The treatment consisted of a classical management of diaphragmatic rupture, with excision of the endometriotic nodule followed by medical ovarian suppression for six months.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xarelto®. Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull. Long-term post-marketing monitoring and independent reports will probably detect the full spectrum of hemorrhagic complications of the use of rivaroxaban. (author)

    Diabetic neuropathy is most common chronic complication of diabetes mellitus. It is responsible for substantial morbidity, increased mortality and impaired quality of life. Patogenesis of diabetic neuropathy is complex. Chronic hyperglycemia is a major factor induces nerve fibers injury. High level of glucose stimulate the polyol pathway causing osmotic stress and enhance reactive oxygen species generation, as well as it play an important role in diabetic angiopathy development. Distal symmetric polineuropathy is most common type of diabetic neuropathy. Many patient may develop combinations of neuropathies concerning somatic and autonomic system. Early diagnosis and administered suitable treatment are necessary to reduce severe complication of diabetic neuropathy as well as strict glycemic control and risk factor increased.

  18. FEL gain optimisation and spontaneous radiation

    Colson have evaluated FEL gains for small deviations from perfect electron beam injection, with radiation of the same polarisation as that of the wiggler fields. We find that for optimum gain the polarisation of the optical field should be the same as that of the spontaneous emission under these conditions. With a helical wiggler the axial oscillations resulting from small departures from perfect electron beam injection lead to injection dependent unequal amplitudes and phases of the spontaneous radiation in the two transverse directions. Viewed along the axis therefore the spontaneous emission is elliptically polarised. The azimuth of the ellipse varies with the difference of phase of the two transverse components of spontaneous emission but the eccentricity remains the same. With planar wigglers the spontaneous emission viewed in the axial direction is linearly polarised, again with an injection dependent azimuth. For optimum coherent gain of a radiation field its polarisation characteristics must be the same as those of the spontaneous radiation with both types of wiggler. Thus, with a helical wiggler and the data reported earlier, an increase of 10% in the FEL gain at the fundamental frequency and of 11% at the fifth harmonic has been calculated in the small gain per pass limit. Larger enhancements in gain may result from more favourable values of input parameters.

    Type 2 diabetes, also known non-insulin-dependent diabetes, is the most prevalent type of the disease and involves defects in the secretion and action of insulin. The aim of the proposed study is to evaluate the efficacy of pre-exercise low-level laser therapy (LLLT) on muscle performance of the quadriceps femoris in individuals with type 2 diabetes. A double-blind, randomized, controlled clinical trial will be carried out in two treatment phases. In the first phase, quadriceps muscle performance will be evaluated using an isokinetic dynamometer and the levels of creatine kinase and lactate dehydrogenase (biochemical markers of muscle damage) will be determined. The participants will then be allocated to four LLLT groups through a randomization process using opaque envelopes: Group A (4 Joules), Group B (6 Joules), Group C (8 Joules) and Group D (0 Joules; placebo). Following the administration of LLLT, the participants will be submitted to an isokinetic eccentric muscle fatigue protocol involving the quadriceps muscle bilaterally. Muscle performance and biochemical markers of muscle damage will be evaluated again immediately after as well as 24 and 48 hours after the experimental protocol. One week after the last evaluation the second phase will begin, during which Groups A, B and C will receive the LLLT protocol that achieved the best muscle performance in phase 1 for a period of 4 weeks. At the end of this period, muscle performance will be evaluated again. The protocol for this study is registered with the World Health Organization under Universal Trial Number U1111-1146-7109. The purpose of this randomized clinical trial is to evaluate the efficacy of pre-exercise LLLT on the performance of the quadriceps muscle (peak torque, total muscle work, maximum power and fatigue index - normalized by body mass) in individuals with DM-2. The study will support the practice of evidence-based to the use of LLLT in improving muscle performance in Individuals with DM-2

    Full Text Available We aimed to selectively breed a spontaneous diabetic gerbil when a sub-line of inbred gerbil showed increased blood glucose levels was found recently. Then we investigated the characteristics including the serum insulin, triglyceride, cholesterol, leptin, adiponectin and explored the underlying molecular mechanism for the diabetic phenotype.The spontaneous diabetic line of gerbils was selectively inbreed the sub-line of gerbil by monitoring blood glucose of each animal. The serum insulin, adiponectin, and leptin levels were tested using an ELISA kit. The expression levels of GLUT4, Akt, leptin, adiponectin, and calpain 10 (CAPN10 were tested by western blot and Quantitative Real-time PCR (qPCR in liver, skeletal muscle, and white adipose.Our results show that the percentages of animals with FPG≥5.2 (mmol/l, PG2h≥6.8 (mmol/l and both FPG≥5.2 and PG2h≥6.8 (mmol/l were increased with the number of breeding generations from F0 (21.33% to F6 (38.46%. These diabetic gerbils exhibited insulin resistance and leptin resistance as well as decreased adiponectin level in the serum. We also observed decreased expression of adiponectin and increased expression of leptin in the skeletal muscle, respectively.These results indicate that we have primarily established a spontaneous diabetic gerbil line, and the diabetic phenotypes may have been accounted for by altered expression of leptin and adiponectin.

  18. Spontaneous body movements in spatial cognition

    Sergiu eTcaci Popescu

    2012-05-01

    Full Text Available People often perform spontaneous body movements during spatial tasks such as giving complex directions or orienting themselves on maps. How are these spontaneous gestures related to spatial problem-solving? We measured spontaneous movements during a perspective-taking task inspired by map reading. Analyzing the motion data to isolate rotation and translation components of motion in specific geometric relation to the task, we found out that most participants executed spontaneous miniature rotations of the head that were significantly related to the main task parameter. These head rotations were as if participants were trying to align themselves with the orientation on the map either in the image plane or on the ground plane, but with tiny amplitudes, typically below 1% of the actual movements. Our results are consistent with a model of sensorimotor prediction driving spatial reasoning. The efference copy of planned movements triggers this prediction mechanism. The movements themselves may then be mostly inhibited; the small spontaneous gestures that we measure are the visible traces of these planned but inhibited actions.

  19. Bilateral spontaneous rupture of 'hale' kidneys

    A rare case of spontaneous bilateral rupture of the kidneys, occurring consecutively over a one-year period in a young male patient with 'hale' kidneys until then, is described. The patient's past history and thorough examination performed do not justify to assign the case under the heading of some of the etiological factors as the underlying cause of spontaneous kidney rupture. The literature survey on spontaneous bilateral non-tumor ruptures of kidneys shows that over a 20-year period, only 3 cases of bilateral spontaneous ruptures have been reported. It is pointed out that panarteritis nodosa followed by hemorrhagic fever with renal syndrome is the commonest underlying cause of such ruptures. Clinically spontaneous ruptures become manifest with emergency condition presenting severe renal colic, impaired to serious general condition, often with acute abdomen and hemodynamic breakdown, and no past history evidence of renal disease or injury. In the initial phase diagnosing is not always easy; it is usually made on the ground of physical examination and the full range of imaging studies used in urological practice and during operative treatment. Emphasis is laid on the fact that the imaging methods are not invariably sufficient to identify the exact etiological factor giving rise to such a severe condition, but nevertheless these methods have an essential practical bearing on diagnosing a rupture.

  20. Surgical management of spontaneous hypertensive brainstem hemorrhage

    2015-09-01

    Full Text Available Spontaneous hypertensive brainstem hemorrhage is the spontaneous brainstem hemorrhage associated with long term hypertension but not having definite focal or objective lesion. It is a catastrophic event which has a poor prognosis and usually managed conservatively. It is not uncommon, especially in eastern Asian populations, accounting approximately for 10% of the intracerebral hemorrhage. Before the advent of computed tomography, the diagnosis of brainstem hemorrhage was usually based on the clinical picture or by autopsy and believed to be untreatable via surgery. The introduction of computed tomography permitted to categorize the subtypes of brainstem hemorrhage with more predicted outcome. Continuous ongoing developments in the stereotactic surgery and microsurgery have added more specific surgical management in these patients. However, whether to manage conservatively or promptly with surgical evacuation of hematoma is still a controversy. Studies have shown that an accurate prognostic assessment based on clinical and radiological features on admission is critical for establishing a reasonable therapeutic approach. Some authors have advocate conservative management, whereas others have suggested the efficacy of surgical treatment in brainstem hemorrhage. With the widening knowledge in microsurgical techniques as well as neuroimaging technology, there seems to have more optimistic hope of surgical management of spontaneous hypertensive brainstem hemorrhage for better prognosis. Here we present five cases of severe spontaneous hypertensive brainstem hemorrhage patients who had undergone surgery; and explore the possibilities of surgical management in patients with the spontaneous hypertensive brainstem hemorrhage.

  1. Cursed lamp: the problem of spontaneous abortion.

    Simkulet, William

    2017-08-09

    Many people believe human fetuses have the same moral status as adult human persons, that it is wrong to allow harm to befall things with this moral status, and thus voluntary, induced abortion is seriously morally wrong. Recently, many prochoice theorists have argued that this antiabortion stance is inconsistent; approximately 60% of human fetuses die from spontaneous abortion, far more than die from induced abortion, so if antiabortion theorists really believe that human fetuses have significant moral status, they have strong moral obligations to oppose spontaneous abortion. Yet, few antiabortion theorists devote any effort to doing so. Many prochoice theorists argue that to resolve this inconsistency, antiabortion theorists should abandon their opposition to induced abortion. Here, I argue that those who do not abandon their opposition to induced abortion but continue to neglect spontaneous abortion act immorally. Aristotle argues that moral responsibility requires both control and awareness; I argue that once an antiabortion theorist becomes aware of the frequency of spontaneous abortion, they have a strong moral obligation to redirect their efforts towards combating spontaneous abortion; failure to do so is morally monstrous. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  2. Norepinephrine storage, distribution, and release in diabetic cardiomyopathy

    The ability of hearts to store, distribute, and release norepinephrine (NE) was investigated in rats 8 wk after the induction of diabetes by an injection of streptozotocin. Chronic diabetes was associated with increased content and concentration of NE in heart and in other tissues such as kidney, brain, and spleen. Reserpine or tyramine treatment resulted in depletion of endogenous cardiac NE in control and diabetic rats. The depletion of NE stores at different times after a dose of reserpine was greater in diabetic hearts. On the other hand, NE stores in diabetic hearts were less sensitive than control hearts to low doses of tyramine but were more sensitive to high doses. The uptake of [ 3 H]NE was greater in diabetic hearts in isolated perfused preparations. In comparison with the control values, diabetic hearts showed a decrease in [ 3 H]NE in the granular fraction and an increase in the supernatant fraction. Diabetic hearts also showed an accelerated spontaneous release of [ 3 H]NE. The increased cardiac NE and the uptake and release of NE in diabetic animals were reversible upon treatment with insulin. These results are consistent with the view that sympathetic activity is increased in diabetic cardiomyopathy and indicate that cardiac NE in diabetic rats is maintained at a higher level partly due to an increased uptake of released NE by adrenergic nerve terminals

  3. Development of Spontaneous Autoimmune Peripheral Polyneuropathy in B7-2–Deficient Nod Mice

    An increasing number of studies have documented the central role of T cell costimulation in autoimmunity. Here we show that the autoimmune diabetes-prone nonobese diabetic (NOD) mouse strain, deficient in B7-2 costimulation, is protected from diabetes but develops a spontaneous autoimmune peripheral polyneuropathy. All the female and one third of the male mice exhibited limb paralysis with histologic and electrophysiologic evidence of severe demyelination in the peripheral nerves beginning at 20 wk of age. No central nervous system lesions were apparent. The peripheral nerve tissue was infiltrated with dendritic cells, CD4+, and CD8+ T cells. Finally, CD4+ T cells isolated from affected animals induced the disease in NOD.SCID mice. Thus, the B7-2–deficient NOD mouse constitutes the first model of a spontaneous autoimmune disease of the peripheral nervous system, which has many similarities to the human disease, chronic inflammatory demyelinating polyneuropathy (CIDP). This model demonstrates that NOD mice have “cryptic” autoimmune defects that can polarize toward the nervous tissue after the selective disruption of CD28/B7-2 costimulatory pathway. PMID:11535635

    A repeated or habitual miscarriage (PSP) is defined as three or more consecutive losses of pregnancy. In the first three months of pregnancy, habitual miscarriages occur in about 1% of pregnant women, out of which 50% are of an unknown etiology. It is believed that among them, the greatest number is the consequence of an inadequate alloimmune response of a women to the pregnancy. The endocrine and immune systems are in a close interaction during the implantation and maintaining of pregnancy. This communication is the most obvious on endometrium of pregnancy decidua. The aim of the study was to identify the number and the subpopulation distribution of the decidual NK cells in the decidua by using an immunohistochemical method. The research included a group of 30 women who had had two spontaneous miscarriages consecutively in the first three months of their pregnancy, while the curettage after the third spontaneous abortion was histopathologically and immunohistochemically analyzed. The control group consisted of 20 women without a problematic reproductive anamnesis, who had had their pregnancy terminated for social reasons. The criteria for the eliminating from the research were the diagnosed uterus anomalies, positive screening on thrombophilia, as well as women suffering from diabetes melitus and the ones with the thyroid gland function disorder. The number and the phenotype structure of the uterus NK cells were significantly different between the decidua of a normal pregnancy and that in PSP. In the decidua in PSP, there were much more NK cells with the phenotype of the peripheral circulation CD57 and CD56dim, while in the decidua of the control group the dominant cells were the typical uNK cell subpopulation CD56bright. The above mentioned results show that the disregulation of the immunocompetent cells of the decidua, by creating an inadequate cytokine milieu, is one of the mechanism of rejecting the semiallogeneic blastocyst.

  6. Spontaneous Regression of Lumbar Herniated Disc

    2009-12-01

    Full Text Available Intervertebral disc herniation of the lumbar spine is a common disease presenting with low back pain and involving nerve root radiculopathy. Some neurological symptoms in the majority of patients frequently improve after a period of conservative treatment. This has been regarded as the result of a decrease of pressure exerted from the herniated disc on neighboring neurostructures and a gradual regression of inflammation. Recently, with advances in magnetic resonance imaging, many reports have demonstrated that the herniated disc has the potential for spontaneous regression. Regression coincided with the improvement of associated symptoms. However, the exact regression mechanism remains unclear. Here, we present 2 cases of lumbar intervertebral disc herniation with spontaneous regression. We review the literature and discuss the possible mechanisms, the precipitating factors of spontaneous disc regression and the proper timing of surgical intervention.

    Computed tomography (CT) was a reliable technique to evaluate the exact size and location of spontaneous intracranial hemorrhage and to predict it's prognosis. Fifty-nine cases of spontaneous intracranial hemorrhage were evaluated and reviewed by CT scan. The following results were obtained. 1. The sex ratio of male to female was 1 to 1.4, The highest incidence was in 6th and 7th decades. 2. The most common cause of spontaneous intracranial hemorrhage was hypertension (74.6%), followed by the aneurysm (13.5%), arteriovenous malformation (5.1%), occlusive vascular disease (3.4%), and blood dyscrasia (3.4%). 3. The most common location was basal ganglia and thalamic hemorrhage (37.3%), followed by lobar hemorrhage (27.1%), cerebellar hemorrhage (13.5%), and subarachnoid hemorrhage (11.9%). 4. Primary intraventricular hemorrhage carried the highest mortality. 5. The larger volume of hematoma, the higher the mortality rate.

  9. Spontaneous Perforation of Pyometra: A Case Report

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01–0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy. Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

    Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis. Clinical and radiological findings were concordant with Müller-Weiss disease, which is a rare disease with complex idiopathic foot condition of the adult tarsal navicular bone characterized by progressive navicular fragmentation and talonavicular joint destruction. The patient was successfully treated with two-staged bilateral talonavicular arthrodesis.

  12. Diabetic embryopathy.

    2012-01-01

    Diabetic embryopathy reflects a scientific enigma--how does a seemingly rich intrauterine environment manage to disturb the development of the embryo? Which compounds in that environment may be teratogenic--and how shall we find them? How can we investigate a putative dose-response nature of the teratogen, i.e., how can we monitor the effects of varied severity of the diabetic state (which can be varied in a number of metabolic ways) on the embryonic development? Here, the whole embryo culture (WEC) technique provides an excellent tool for such studies. WEC is thus currently used to investigate the effect of graded levels of diabetes (e.g., hyperglycemia, hyperketonemia, increased branched chain amino acid (BCAA) levels), and putative antiteratogenic agents (antioxidants, folic acid, arachidonic acid, inositol), as well as the effect of different embryonic genotypes on diabetes-induced (mal)development. WEC is the only method, which is able to couple specific embryonic maldevelopment to precise changes in substrate levels or the (epi)genotype of the embryo. Using this method, we have been able to demonstrate that a diabetic environment--culture of embryos in serum from diabetic animals or in serum with increased levels of glucose, β-hydroxybutyrate or α-ketoisocaproic acid (KIC)--causes increased embryonic maldevelopment, and that this dysmorphogenesis is blocked by the addition of ROS scavenging agents to the culture medium. Genetically, others and we have demonstrated that Pax-3 downregulation predisposes for diabetes-induced dysmorphogenesis.

  13. On spontaneous breakdown in Σ-models

    1975-01-01

    The group theory aspects of spontaneous breakdown in linear Σ-models are discussed. General conditions are formulated under which multiplet of group G (compact or noncompact) is suitable for constructing the Σ-model with a given subgroup of stability of vacuum. It is shown that the Σ-models of spontaneously broken space-time symmetries can be constructed in general only if some extra coordinates are introduced in addition to an ordinary 4-coordinate xsub(μ). The connection between Σ-models of internal symmetries and appropriate nonlinear realizations has also been investigated

    This is a report of two cases of spontaneous temporal encephalocele: one was anteroinferior and presented with epilepsy; the other was posteroinferior and presented with facial neuritis and labyrinthitis. Spontaneous temporal encephalocele is relatively rare and apparently not familiar to a majority of primary physicians. It may present with a variety of symptoms according to its anatomical location, including cerebrospinal fluid fistulas, recurrent meningitis, chronic otitis media, hearing loss, facial nerve palsy and medically intractable epilepsy. Attention should be paid to this disease entity, as it is easily overlooked in imaging studies and can leave serious neurological deficits. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

  16. Need for spontaneous breakdown of chiral symmetry

    Salomone, A.; Schechter, J.; Tudron, T.

    1981-01-01

    The question of whether the chiral symmetry of the theory of strong interactions (with massless quarks) is required to be spontaneously broken is examined in the framework of a previously discussed effective Lagrangian for quantum chromodynamics. The assumption that physical masses of the theory be finite leads in a very direct way to the necessity of spontaneous breakdown. This result holds for all N/sub F/> or =2, where N/sub F/ is the number of different flavors of light quarks. The atypical cases N/sub F/ = 1,2 are discussed separately

  17. Spontaneous subdural hematoma associated to Duret hemorrhage

    2015-03-01

    Full Text Available Subdural hematoma (SH is a neurosurgical emergency, usually caused by head trauma. Non-traumatic causes include aneurysm or arterial–venous malformation rupture, coagulopathy and others. We report the case of a 66 year-old man who developed apparently unprovoked signs of increased intracranial pressure. Brain computed tomography scan showed an acute spontaneous SH, surgically treated. Throughout surgery, a ruptured cortical artery with intensive bleeding appeared and was cauterized. After surgery, patient remained comatose and a new CT demonstrated Duret hemorrhage at the brainstem. Acute spontaneous SH of arterial origin is rare and highly lethal, in which a good prognosis relies on early diagnosis and treatment.

  18. Primer on spontaneous heating and pyrophoricity

    Energy Technology Data Exchange (ETDEWEB)

    1994-12-01

    This primer was prepared as an information resource for personnel responsible for operation of DOE nuclear facilities. It has sections on combustion principles, spontaneous heating/ignition of hydrocarbons and organics, pyrophoric gases and liquids, pyrophoric nonmetallic solids, pyrophoric metals (including Pu and U), and accident case studies. Although the information in this primer is not all-encompassing, it should provide the reader with a fundamental knowledge level sufficient to recognize most spontaneous combustion hazards and how to prevent ignition and widespread fires. This primer is provided as an information resource only, and is not intended to replace any fire protection or hazardous material training.

  19. Cavity enhanced rephased amplified spontaneous emission

    A Williamson, Lewis; J Longdell, Jevon

    2014-01-01

    Amplified spontaneous emission is usually treated as an incoherent noise process. Recent theoretical and experimental work using rephasing optical pulses has shown that rephased amplified spontaneous emission (RASE) is a potential source of wide bandwidth time-delayed entanglement. Due to poor echo efficiency the plain RASE protocol does not in theory achieve perfect entanglement. Experiments done to date show a very small amount of entanglement at best. Here we show that RASE can, in principle, produce perfect multimode time-delayed two mode squeezing when the active medium is placed inside a Q-switched cavity. (paper)

    2013-07-01

    We discuss various strategies for regularising supersymmetric quantum field theories on a space-time lattice. In general, simulations of lattice models with spontaneously broken supersymmetry suffer from a fermion sign problem related to the vanishing of the Witten index. We discuss a novel approach which evades this problem in low dimensions by formulating the path integral on the lattice in terms of fermion loops. Then we present exact results on the spectrum and the Witten index for N=2 supersymmetric quantum mechanics and results from simulations of the spontaneously broken N=1 Wess-Zumino model.

  1. Diabetic nephropathy

    2009-09-01

    Full Text Available Abstract Diabetic nephropathy is the leading cause of chronic renal disease and a major cause of cardiovascular mortality. Diabetic nephropathy has been categorized into stages: microalbuminuria and macroalbuminuria. The cut-off values of micro- and macroalbuminuria are arbitrary and their values have been questioned. Subjects in the upper-normal range of albuminuria seem to be at high risk of progression to micro- or macroalbuminuria and they also had a higher blood pressure than normoalbuminuric subjects in the lower normoalbuminuria range. Diabetic nephropathy screening is made by measuring albumin in spot urine. If abnormal, it should be confirmed in two out three samples collected in a three to six-months interval. Additionally, it is recommended that glomerular filtration rate be routinely estimated for appropriate screening of nephropathy, because some patients present a decreased glomerular filtration rate when urine albumin values are in the normal range. The two main risk factors for diabetic nephropathy are hyperglycemia and arterial hypertension, but the genetic susceptibility in both type 1 and type 2 diabetes is of great importance. Other risk factors are smoking, dyslipidemia, proteinuria, glomerular hyperfiltration and dietary factors. Nephropathy is pathologically characterized in individuals with type 1 diabetes by thickening of glomerular and tubular basal membranes, with progressive mesangial expansion (diffuse or nodular leading to progressive reduction of glomerular filtration surface. Concurrent interstitial morphological alterations and hyalinization of afferent and efferent glomerular arterioles also occur. Podocytes abnormalities also appear to be involved in the glomerulosclerosis process. In patients with type 2 diabetes, renal lesions are heterogeneous and more complex than in individuals with type 1 diabetes. Treatment of diabetic nephropathy is based on a multiple risk factor approach, and the goal is retarding the

  7. Obviating much of the need for insulin therapy in type 2 diabetes mellitus: A re-assessment of insulin therapy's safety profile.

    Schwartz, Stanley S; Jellinger, Paul S; Herman, Mary E

    2016-08-01

    Current processes of care for diabetes mellitus (DM) were shaped during the era when insulin therapy was considered inexorable to the management of advanced stage type 2 (T2DM), though this no longer appears to be categorically true. There are also dashed hopes that insulin therapy can prevent or stall diabetes. While exogenous insulin remains a life-sparing tool for fully insulin-dependent DM, insulin therapy-induced hyperinsulinemia now appears to contribute to serious safety issues beyond hypoglycemia and weight gain. Iatrogenic and compensatory hyperinsulinemia are metabolic disruptors of β-cells, liver, muscle, kidney, brain, heart and vasculature, inflammation, and lipid homeostasis, among other systems. This may compromise β-cells, exacerbate insulin resistance (IR), and increase risk of cardiovascular (CV) disease. Striking associations between exogenous insulin and risks of CV events, cancer, and all-cause mortality in clinical trial and real-world cohorts caution that insulin may pose more harm than previously evidenced. At our disposal are numerous alternate tools that, alone or in combination, efficaciously manage hyperglycemia and glucolipotoxicity, and do so without inducing hypoglycemia, weight gain, or hyperinsulinemia. Moreover, these new tools support true precision therapy, as modern day drug classes can be aligned with the various mediating pathways of hyperglycemia at work in any given patient. Some also appear to promote β-cell survival, with intriguing data being presented for newer agents, such as incretins. As such, we encourage preferential use of non-insulin antidiabetic agents to injected insulin for the management of non-insulin-dependent patients with T2DM, including in advanced stage T2DM. The goal of this article is to augment existing literature to 1) correct misconceptions on the rationale and necessity for insulin therapy in T2DM, 2) discuss emerging negative safety data with insulin therapy, and, 3) offer a practical means to

    Diabetes insipidus is an uncommon disorder of water-electrolyte balance characterized by the excretion of abnormally large volumes of diluted urine (polyuria) and increased fluid intake (polydipsia). The disease may result from the insufficient production of vasopressin, its increased degradation, an impaired response of kidneys to vasopressin, or may be secondary to excessive water intake. Patients with severe and uncompensated symptoms may develop marked dehydration, neurologic symptoms and encephalopathy, and therefore diabetes insipidus can be a life-threatening condition if not properly diagnosed and managed. Patients with diabetes insipidus require treatment with desmopressin or drugs increasing sensitivity of the distal nephron to vasopressin, but this treatment may be confusing because of the disorder's variable pathophysiology and side-effects of pharmacotherapy. This review summarizes the current knowledge on different aspects of the pathophysiology, classification, clinical presentation, diagnosis, and management of diabetes insipidus. The reader is also provided with some practical recommendations on dealing with patients suffering from this disease.

We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods: This case-control study included the case group (n=331 experiencing a spontaneous abortion before 14 weeks of pregnancy and the control group (n=331 who were healthy pregnant women over 14 weeks of pregnancy. The participants filled out Food Frequency Questionnaire (FFQ, in which they reported their frequency of consumption for a given serving of each food item during the past three months, on a daily, weekly or monthly basis. The reported frequency for each food item was converted to a daily intake. Then, consumption of nutrients was compared between the two groups. Results: There are significant differences between the two groups regarding consumed servings/day of vegetables, bread and cereal, meat, poultry, fish, eggs, beans, fats, oils and dairy products (P=0.012, P<0.001, P=0.004, P<0.001, P=0.019, respectively.

    Full Text Available AIMS: Spontaneous ruptured hepatocellular adenoma (SRHA is a rare life-threatening condition that may require surgical treatment to control hemorrhaging and also stabilize the patient. We report a series of emergency surgeries performed at our institution for this condition. METHODS: We reviewed medical records and radiology files of 28 patients (from 1989 to 2006 with a proven diagnosis of hepatocellular adenoma (HA. Three (10.7% of 28 patients had spontaneous ruptured hepatocellular adenoma, two of which were associated with intrahepatic hemorrhage while one had intraperitoneal bleeding. Two patients were female and one was male. Both female patients had a background history of oral contraceptive use. Sudden abdominal pain associated with hemodynamic instability occurred in all patients who suffered from spontaneous ruptured hepatocellular adenoma. The mean age was 41.6 years old. The preoperative assessment included liver function tests, ultrasonography and computed tomography. RESULTS: The surgical approaches were as follows: right hemihepatectomy for controlling intraperitoneal bleeding, and right extended hepatectomy and non-anatomic resection of the liver for intrahepatic hemorrhage. There were no deaths, and the postoperative complications were bile leakage and wound infection (re-operation, as well as intraperitoneal abscess (re-operation and pleural effusion. CONCLUSION: Spontaneous ruptured hepatocellular adenoma may be treated by surgery for controlling hemorrhages and stabilizing the patient, and the decision to operate depends upon both the patient's condition and the expertise of the surgical team.

    Why is it so difficult to resist the desire to use social media? One possibility is that frequent social media users possess strong and spontaneous hedonic reactions to social media cues, which, in turn, makes it difficult to resist social media temptations. In two studies (total N = 200), we investigated less-frequent and frequent social media users' spontaneous hedonic reactions to social media cues using the Affect Misattribution Procedure-an implicit measure of affective reactions. Results demonstrated that frequent social media users showed more favorable affective reactions in response to social media (vs. control) cues, whereas less-frequent social media users' affective reactions did not differ between social media and control cues (Studies 1 and 2). Moreover, the spontaneous hedonic reactions to social media (vs. control) cues were related to self-reported cravings to use social media and partially accounted for the link between social media use and social media cravings (Study 2). These findings suggest that frequent social media users' spontaneous hedonic reactions in response to social media cues might contribute to their difficulties in resisting desires to use social media.

    2017-05-01

    Research on analogical problem solving has shown that people often fail to spontaneously notice the relevance of a semantically remote source analog when solving a target problem, although they are able to form mappings and derive inferences when given a hint to recall the source. Relatively little work has investigated possible individual differences that predict spontaneous transfer, or how such differences may interact with interventions that facilitate transfer. In this study, fluid intelligence was measured for participants in an analogical problem-solving task, using an abridged version of the Raven's Progressive Matrices (RPM) test. In two experiments, we systematically compared the effect of augmenting verbal descriptions of the source with animations or static diagrams. Solution rates to Duncker's radiation problem were measured across varying source presentation conditions, and participants' understanding of the relevant source material was assessed. The pattern of transfer was best fit by a moderated mediation model: the positive impact of fluid intelligence on spontaneous transfer was mediated by its influence on source comprehension; however, this path was in turn modulated by provision of a supplemental animation via its influence on comprehension of the source. Animated source depictions were most beneficial in facilitating spontaneous transfer for those participants with low scores on the fluid intelligence measure.

  18. Spontaneous sensorimotor coupling with multipart music.

    Hurley, Brian K; Martens, Peter A; Janata, Petr

    Music often evokes spontaneous movements in listeners that are synchronized with the music, a phenomenon that has been characterized as being in "the groove." However, the musical factors that contribute to listeners' initiation of stimulus-coupled action remain unclear. Evidence suggests that newly appearing objects in auditory scenes orient listeners' attention, and that in multipart music, newly appearing instrument or voice parts can engage listeners' attention and elicit arousal. We posit that attentional engagement with music can influence listeners' spontaneous stimulus-coupled movement. Here, 2 experiments-involving participants with and without musical training-tested the effect of staggering instrument entrances across time and varying the number of concurrent instrument parts within novel multipart music on listeners' engagement with the music, as assessed by spontaneous sensorimotor behavior and self-reports. Experiment 1 assessed listeners' moment-to-moment ratings of perceived groove, and Experiment 2 examined their spontaneous tapping and head movements. We found that, for both musically trained and untrained participants, music with more instruments led to higher ratings of perceived groove, and that music with staggered instrument entrances elicited both increased sensorimotor coupling and increased reports of perceived groove. Although untrained participants were more likely to rate music as higher in groove, trained participants showed greater propensity for tapping along, and they did so more accurately. The quality of synchronization of head movements with the music, however, did not differ as a function of training. Our results shed new light on the relationship between complex musical scenes, attention, and spontaneous sensorimotor behavior.
