    OBJECTIVES: Natural enzymes mouthwash has been proposed as salivary substitutes to treat xerostomia. This study aims to evaluate the efficacy of the mouthwash to treat xerostomia.

    MATERIALS AND METHODS: A double-blind, parallel group randomised control clinical trial involving N = 49 adult participants with xerostomia was carried out. Intervention group received natural enzymes moisturising mouthwash (with active ingredients lactoferrin, lysozyme, lactoperoxidase and glucose oxidase); while control group received benzydamine mouthwash. Mouthwashes were repacked, labelled with specific code, and were given to participants by third-party. Subjects were instructed to rinse with the mouthwash 4 times per day at a specific period, for 2 weeks. Symptoms of xerostomia were assessed using Xerostomia Inventory at day 0 and 14; together with the assessment of Clinical Oral Dryness Score (CODS), and measurement of resting and stimulated salivary flow rate.

    RESULTS: 48 participants completed the clinical follow-up, and n = 1 had lost of follow-up. From the 48 participants, n = 23 received natural enzymes mouthwash, while n = 25 received benzydamine mouthwash. Intervention group achieved reduction in symptoms of xerostomia from baseline. Intervention group also showed significantly better improvements in the cognitive perception of dry mouth and oromotor function such as chewing, swallowing and speech of the participants; and reduction in waking up at night to drink water (p

    A new implantable electrocatalytic glucose sensor for subcutaneous glucose monitoring has been fabricated by immobilizing glucose oxidase on a chemically modified carbon fiber. The sensor was inserted subcutaneously on a male spraguely rat without any incision after dipping the microsensor in the rat's serum for 3 days. The so called "stained" microsensor, operated in the amperometric mode with an applied potential of +0.23 V versus Ag|AgCl, was able to directly measure the glucose concentration upon infusion of glucose. The results obtained were encouraging, with the response time was less than 2s and the apparent Michaelis-Menten value at 5.1+/-0.5mM. The "stained" microsensor shows good stability and reproducibility with constant response spanned over 25 days. Most common interferences in glucose analysis were minimized by the outerlayer Nafion. Hematology examinations showed minimal material-tissue interaction. Use of such mechanical devices will allow a more refined understanding towards glucose control in diabetic patients as the implanted microsensor was not effected by biocompatibility failures.

    PMID: 15468814
    Considerable effort has been focused on the method of immobilizing glucose oxidase (GOD) for amperometric glucose biosensors since the technique employed may influence the available activity of the enzyme and thus affect the performance of the sensor. Narrow measuring range and low current response are still considered problems in this area. In this work, poly(vinyl alcohol)(PVA) was investigated as a potential matrix for GOD immobilization. GOD was entrapped in cross-linked PVA. The use of a PVA-GOD membrane as the enzymatic component of a glucose biosensor was found to be promising in both the magnitude of its signal and its relative stability over time. The optimum PVA-GOD membrane (cross-linking density of 0.06) was obtained through careful selection of the cross-linking density of the PVA matrix.

    A high sodium concentration is known to antagonize local anesthetics when infiltrated around neural tissue. Thus, we hypothesized that the onset time for sensory and motor blockade, in supraclavicular brachial plexus block using ropivacaine diluted with dextrose would be shorter than with saline.

    PLoS One, 2015;10(3):e0111859.
    PMID: 25789757 DOI: 10.1371/journal.pone.0111859
    An amperometric enzyme-electrode was introduced where glucose oxidase (GOD) was immobilized on chitosan membrane via crosslinking, and then fastened on a platinum working electrode. The immobilized enzyme showed relatively high retention activity. The activity of the immobilized enzyme was influenced by its loading, being suppressed when more than 0.6 mg enzyme was used in the immobilization. The biosensor showing the highest response to glucose utilized 0.21 ml/cm2 thick chitosan membrane. The optimum experimental conditions for the biosensors in analysing glucose dissolved in 0.1 M phosphate buffer (pH 6.0) were found to be 35°C and 0.6 V applied potential. The introduced biosensor reached a steady-state current at 60 s. The apparent Michaelis-Menten constant ([Formula: see text]) of the biosensor was 14.2350 mM, and its detection limit was 0.05 mM at s/n > 3, determined experimentally. The RSD of repeatability and reproducibility of the biosensor were 2.30% and 3.70%, respectively. The biosensor was showed good stability; it retained ~36% of initial activity after two months of investigation. The performance of the biosensors was evaluated by determining the glucose content in fruit homogenates. Their accuracy was compared to that of a commercial glucose assay kit. There was no significance different between two methods, indicating the introduced biosensor is reliable.

    Background: Impaired fasting glucose (IFG) poses a higher risk of diabetes. Honey has been reported to improve metabolic abnormalities including lowering hyperglycemia. This study is sought at determining the effect of Malaysian Kelulut honey (KH) on fasting glucose levels and metabolic parameters in IFG patients.
    Methods: This quasi-experimental intervention study of 30-day duration was conducted among 60 adult patients with IFG. They were allocated into taking 30 g/day KH group (experimental group, n=30) and not taking KH group (control group, n=30). Body mass index (BMI), waist circumference, blood pressure (BP), fasting glucose, and lipid profile levels (total cholesterol, triglyceride, high-density lipoprotein, and low-density lipoprotein) were measured before and after treatment.
    Results: There was no significant difference in all measured variables at day 30 compared to day 1 within both groups. Similarly, all measured variables neither at day 1 nor at day 30 had shown a statistically significant difference between the groups.
    Conclusions: Daily intake of 30 g KH for 30 days resulted in insignificant effect on fasting glucose, fasting lipid profiles, and other metabolic parameters in patients with IFG. Further studies that employ longer study duration are needed to ascertain the finding.

  8. Modeling of oscillatory bursting activity of pancreatic beta-cells under regulated glucose stimulation
    Chew YH, Shia YL, Lee CT, Majid FA, Chua LS, Sarmidi MR, et al.
    Mol Cell Endocrinol, 2009 Aug 13;307(1-2):57-67.
    PMID: 19524127 DOI: 10.1016/j.mce.2009.03.005
    A mathematical model to describe the oscillatory bursting activity of pancreatic beta-cells is combined with a model of glucose regulation system in this work to study the bursting pattern under regulated extracellular glucose stimulation. The bursting electrical activity in beta-cells is crucial for the release of insulin, which acts to regulate the blood glucose level. Different types of bursting pattern have been observed experimentally in glucose-stimulated islets both in vivo and in vitro, and the variations in these patterns have been linked to changes in glucose level. The combined model in this study enables us to have a deeper understanding on the regime change of bursting pattern when glucose level changes due to hormonal regulation, especially in the postprandial state. This is especially important as the oscillatory components of electrical activity play significant physiological roles in insulin secretion and some components have been found to be lost in type 2 diabetic patients.

    Nitric oxide influences intramuscular signaling that affects skeletal muscle glucose uptake during exercise. The role of the main NO-producing enzyme isoform activated during skeletal muscle contraction, neuronal nitric oxide synthase-μ (nNOSμ), in modulating glucose uptake has not been investigated in a physiological exercise model. In this study, conscious and unrestrained chronically catheterized nNOSμ(+/+) and nNOSμ(-/-) mice either remained at rest or ran on a treadmill at 17 m/min for 30 min. Both groups of mice demonstrated similar exercise capacity during a maximal exercise test to exhaustion (17.7 ± 0.6 vs. 15.9 ± 0.9 min for nNOSμ(+/+) and nNOSμ(-/-), respectively, P > 0.05). Resting and exercise blood glucose levels were comparable between the genotypes. Very low levels of NOS activity were detected in skeletal muscle from nNOSμ(-/-) mice, and exercise increased NOS activity only in nNOSμ(+/+) mice (4.4 ± 0.3 to 5.2 ± 0.4 pmol·mg(-1)·min(-1), P < 0.05). Exercise significantly increased glucose uptake in gastrocnemius muscle (5- to 7-fold) and, surprisingly, more so in nNOSμ(-/-) than in nNOSμ(+/+) mice (P < 0.05). This is in parallel with a greater increase in AMPK phosphorylation during exercise in nNOSμ(-/-) mice. In conclusion, nNOSμ is not essential for skeletal muscle glucose uptake during exercise, and the higher skeletal muscle glucose uptake during exercise in nNOSμ(-/-) mice may be due to compensatory increases in AMPK activation.

    MyJurnal
    Delay in childbearing, family history of type 2 diabetes mellitus and obesity in childbearing years increases a possibility of glucose intolerance or overt diabetes in pregnancy which may remain unrecognised unless an oral glucose tolerance test is done.The International Association of Diabetes and Pregnancy Study Group (IADPSG, 2010) recommended the detection and diagnosis of hyperglycaemic disorders in pregnancy at two stages of pregnancy, the first stage looking for ‘overt diabetes’ in early pregnancy based on risk factors like age, past history of gestational diabetes and obesity and the second stage where ‘gestational diabetes’ at 24-28 weeks with 75 g oral glucose tolerance test. Although the one step approach with 75 g of glucose offers operational convenience in diagnosing gestational diabetes, there are concerns raised by the National Institute of Health in the recent consensus statement, supporting the two step approach (50-g, 1-hour loading test screening 100-g, 3-hour oral glucose tolerance test) as the recommended approach for detecting gestational diabetes. Medical nutrition therapy (MNT) with well-designed meal plan and appropriate exercise achieves normoglycemia without inducing ketonemia and weight loss in most pregnant women with glucose intolerance. Rapidly acting insulin analogues, such as insulin lispro and aspart are safe in pregnancy and improve postprandial glycemic control in women with pre-gestational diabetes. The long acting analogues (Insulin detemir and glargine) though proven to be safe in pregnancy, do not confer added advantage if normoglycemia is achieved with intermediate insulin (NPH). Current evidence indicates the safe use of glyburide and metformin in the management of Type 2 diabetes and gestational diabetes as other options. However, it is prudent to communicate to the women that there is no data available on the long-term health of the offspring and the safety of these oral hypoglycemic drugs are limited to the prenatal period.

    Int J Med Mushrooms, 2016;18(9):821-831.
    PMID: 27910773
    The edible mushroom Pleurotus giganteus was tested for its effect on adipocyte differentiation and glucose uptake activity in 3T3-L1 cells. The basidiocarps of P. giganteus were soaked in methanol to obtain a crude methanol extract and then fractionated to obtain an ethyl acetate extract. In this study, cell proliferation was measured using an MTT assay, lipid accumulation using an Oil Red O assay, and glucose uptake using a fluorescence glucose uptake assay. Gene expression was measured via real-time polymerase chain reaction analysis with TaqMan primer. Ethyl acetate extract significantly enhanced adipogenic differentiation and glucose uptake in 3T3-L1 adipocytes via the expression of sterol regulatory element-binding protein, peroxisome proliferator-activated receptor γ, and phos-phatidylinositol 3-kinase/Akt. Glucose uptake was facilitated by the highly expressed glucose transporters Glut1 and Glut4. Taken together, these results suggest that P. giganteus ethyl acetate extract has an insulin-sensitizing effect on adipocytes and has potential as an adjuvant for the management of type 2 diabetes.

    PMID: 29732710 DOI: 10.1002/psp4.12302
    In antidiabetic drug development, phase I studies usually involve short-term glucose provocations. Multiple designs are available for these provocations (e.g., meal tolerance tests (MTTs) and graded glucose infusions (GGIs)). With a highly nonlinear, complex system as the glucose homeostasis, the various provocations will contribute with different information offering a rich choice. Here, we investigate the most appropriate study design in phase I for several hypothetical mechanisms of action of a study drug. Five drug effects in diabetes therapeutic areas were investigated using six study designs. Power to detect drug effect was assessed using the likelihood ratio test, whereas precision and accuracy of the quantification of drug effect was assessed using stochastic simulation and estimations. An overall summary was developed to aid designing the studies of antihyperglycemic drug development using model-based analysis. This guidance is to be used when the integrated glucose insulin model is used, involving the investigated drug mechanisms of action.

  13. Impulsiveness, postprandial blood glucose, and glucoregulation affect measures of behavioral flexibility
    Riby LM, Lai Teik Ong D, Azmie NBM, Ooi EL, Regina C, Yeo EKW, et al.
    Nutr Res, 2017 Dec;48:65-75.
    PMID: 29246282 DOI: 10.1016/j.nutres.2017.10.011
    Behavioral flexibility (BF) performance is influenced by both psychological and physiological factors. Recent evidence suggests that impulsivity and blood glucose can affect executive function, of which BF is a subdomain. Here, we hypothesized that impulsivity, fasting blood glucose (FBG), glucose changes (ie, glucoregulation) from postprandial blood glucose (PBG) following the intake of a 15-g glucose beverage could account for variability in BF performance. The Stroop Color-Word Test and the Wisconsin Card Sorting Test (WCST) were used as measures of BF, and the Barratt Impulsiveness Scale (BIS-11) to quantify participants' impulsivity. In Study 1, neither impulsivity nor FBG could predict performance on the Stroop or the WCST. In Study 2, we tested whether blood glucose levels following the intake of a sugary drink, and absolute changes in glucose levels following the intake of the glucose beverage could better predict BF. Results showed that impulsivity and the difference in blood glucose between time 1 (postprandial) and time 2, but not blood glucose levels at time 2 per se could account for variation in performance on the WCST but not on the Stroop task. More specifically, lower impulsivity scores on the BIS-11, and smaller differences in blood glucose levels from time 1 to time 2 predicted a decrease in the number of total and perseverative errors on the WCST. Our results show that measures of impulsivity and glucoregulation can be used to predict BF. Importantly our data extend the work on glucose and cognition to a clinically relevant domain of cognition.

    The conversion of hexavalent molybdenum (Mo (VI)) to Mo-blue is a bioremediation technique
    which reduces the toxicity of molybdenum to a less toxic form by bacteria. The aim of this study
    is to determine the optimum conditions of significant parameters or variables that affect the
    reduction of Mo (VI) to Mo-blue by the local isolate identified as Serratia sp. strain MIE2.
    Response Surface Methodology (RSM) was used in this study to optimize the reduction process
    using Central Composite Design (CCD) as an optimization matrix. The optimum conditions
    predicted by RSM using the desirability function for the reduction process were 20 mM
    molybdate concentration, 3.95 mM phosphate, 6.25 pH and 25 g/L glucose and Mo-blue
    production occurred at the absorbance value of 20.5 at 865 nm. The validation of the predicted
    optimum points showed the Mo-blue production occurred at the absorbance value of 21.85 with
    a deviation around 6.6 % from the RSM predicted value.

    Chemical structures derived from marine foods are highly diverse and pharmacologically promising. In particular, chitooligosaccharides (COS) present a safe pharmacokinetic profile and a great source of new bioactive polymers. This review describes the antioxidant, anti-inflammatory, and antidiabetic properties of COS from recent publications. Thus, COS constitute an effective agent against oxidative stress, cellular damage, and inflammatory pathogenesis. The mechanisms of action and targeted therapeutic pathways of COS are summarized and discussed. COS may act as antioxidants via their radical scavenging activity and by decreasing oxidative stress markers. The mechanism of COS antidiabetic effect is characterized by an acceleration of pancreatic islets proliferation, an increase in insulin secretion and sensitivity, a reduction of postprandial glucose, and an improvement of glucose uptake. COS upregulate the GLUT2 and inhibit digestive enzyme and glucose transporters. Furthermore, they resulted in reduction of gluconeogenesis and promotion of glucose conversion. On the other hand, the COS decrease inflammatory mediators, suppress the activation of NF-κB, increase the phosphorylation of kinase, and stimulate the proliferation of lymphocytes. Overall, this review brings evidence from experimental data about protective effect of COS.

  16. Fulltext Modified bicinchoninic acid assay for accurate determination of variable length reducing sugars in carbohydrates

    The accurate determination of reducing ends of malto-oligosaccharides is essential for calculating the enzyme activities of starch debranching enzymes. The suitability of the 3,5-Dinitrosalicylic acid (DNS) method, the Dygert method, and the Bicinchoninic acid (BCA) method for accurate determination of reducing ends from malto-oligosaccharides of different chain lengths is compared. The results showed that BCA assay was much more accurate than the other assays. The results for the BCA assay showed that different malto-oligosaccharides gave observed (measured) values that were significantly similar to the expected (predetermined) values. In contrast, the DNS and Dygert assays underestimated the amount of reducing sugar present for glucose. Furthermore, both DNS and Dygert methods showed increasing degree of overestimation of the amount of reducing sugar present with the increasing length of the malto-oligosaccharide sugar chains. The BCA assay can suitably quantify reducing sugars even in mixtures of oligosaccharides with different chain lengths. Thus, enzyme activities can be measured without bias towards higher values for enzymes that preferentially cleave the longer chain lengths.

    PMID: 30902242 DOI: 10.1016/j.wasman.2019.01.035
    Microwave assisted acid hydrolysis (H2SO4 and HCl with >0.5 mol/L) to produce bioethanol from sago pith waste (SPW) was studied. The energy consumption for microwave hydrolysis at different energy inputs and acid concentration were calculated. The overall energy consumption for bioethanol fuel production from SPW was assessed. A maximum of 88% glucose yield and 80% ethanol yield (3.1 g ethanol per 10 g SPW) were obtained using 1.0 mol/L H2SO4. Microwave hydrolysis using 1.0 mol/L H2SO4 consumed the minimum energy of 8.1 kJ to produce 1 g glucose from SPW when energy input was fixed at 54 kJ (900 W for 1 min). In general, 1 g glucose can produce 16 kJ. The overall energy consumption for fuel grade bioethanol production from SPW was 31.77 kJ per g ethanol, which was slightly higher than the lower heating values of ethanol (26.74 kJ/g ethanol).

  18. Fulltext Bimodality in blood glucose distribution: is it universal?
    Lim TO, Bakri R, Morad Z, Hamid MA
    Diabetes Care, 2002 Dec;25(12):2212-7.
    PMID: 12453963 DOI: 10.2337/diacare.25.12.2212
    OBJECTIVE: Bimodality in blood glucose (BG) distribution has been demonstrated in several populations with a high prevalence of diabetes and obesity. However, other population studies had not found bimodality, thus casting doubt on its universality. We address this question in four ethnic populations-namely Malay, Chinese, Indian, and the indigenous people of Borneo.

    RESEARCH DESIGN AND METHODS: A national health survey was conducted in Malaysia in 1996. A total of 18,397 subjects aged > or =30 years had post-challenge BG measurements taken. To test whether BG was consistent with a bimodal distribution, we fitted unimodal normal and skewed distribution as well a mixture of two normal distributions to the data by age and ethnic groups.

    RESULTS: Age-specific prevalence of diabetes varied from 1.3 to 26.3%. In all ethnic/age groups, the bimodal model fitted the log BG data better (likelihood ratio tests, all P values <0.001).

    CONCLUSIONS: Bimodality in BG distribution is demonstrable even in populations with a very low prevalence of diabetes and obesity. Previous studies that found unimodality had failed to detect the second mode because of inadequate sample size, bias due to treatment of subjects with known diabetes, and inclusion of subjects with type 1 diabetes in the sample. Bimodality implies that diabetes is a distinct entity rather than an arbitrarily defined extreme end of a continuously distributed measurement.

    Clin Nutr ESPEN, 2021 12;46:314-324.
    PMID: 34857213 DOI: 10.1016/j.clnesp.2021.09.738
    BACKGROUND AND AIMS: It is unknown whether dietary modifications during Ramadan could influence glycemic control in diabetes. This study assessed dietary intake following structured Ramadan nutrition therapy and determined the association between changes in dietary intake and glycemic control parameters in patients with type 2 diabetes.

    METHODS: This was an 8-week, parallel-group, non-randomised study of 60 type 2 diabetes patients who opted for structured Ramadan Nutrition Therapy (sRNT; n = 38) or standard care (SC; n = 22) group. The sRNT group received a structured Ramadan Nutrition Plan incorporated with diabetes-specific formula throughout the study, while SC received standard nutrition care. The 3-day food records assessed dietary intake at three-time points.

    RESULTS: At baseline, dietary characteristics were comparable; both groups had macronutrient intakes within the recommended range, but inadequate intakes of fiber and 11 essential micronutrients. After 8 weeks, the sRNT group significantly reduced intakes of carbohydrate, dietary glycemic index, glycemic load, and increased percentage of total energy intake from protein, fiber, pyridoxine, vitamin C, vitamin D, calcium, and chromium compared with the SC group. In the sRNT group, compliance to diabetes-specific formula predicted changes in HbA1c (p = 0.024), while fiber intake predicted fasting plasma glucose (p = 0.035), after adjusting for age, sex, weight changes and other dietary variables.

    CONCLUSION: Intakes of certain nutrients improved significantly in sRNT group after 8 weeks of receiving a structured Ramadan Nutrition Plan compared to the standard care. The structured Ramadan Nutrition Plan with the incorporation of diabetes-specific formula significantly improved glycemic control and dietary adequacy during Ramadan fasting.

  20. Probiotics for the management of type 2 diabetes mellitus: A systematic review and meta-analysis
    Samah S, Ramasamy K, Lim SM, Neoh CF
    Diabetes Res Clin Pract, 2016 Jun 18;118:172-182.
    PMID: 27388674 DOI: 10.1016/j.diabres.2016.06.014
    AIMS: To systematically review evidence of probiotic interventions against type 2 diabetes mellitus (T2DM) and analyse the effects of probiotics on glycaemic control among T2DM patients.
    METHODS: Electronic search using five electronic databases was performed until October 2015. Relevant studies were identified, extracted and assessed for risk of bias. The primary outcomes of this review were glycated haemoglobin (HbA1c) and fasting blood glucose (FBG). Fasting plasma insulin, homeostasis model assessment-insulin resistance, C-reactive protein, interleukin-6 and malondialdehyde, were identified as the secondary outcomes. Mean differences (MD) between probiotics and control groups for all outcomes were pooled using either Fixed- or Random-Effect Model. Statistical heterogeneity was assessed using I(2) and Chi(2) tests.
    RESULTS: Six randomised controlled trials (RCTs) were included in the systematic review, whereas only five were included in meta-analysis. Most RCTs were presented with low or unclear risk of bias. When compared to placebo, FBG was significantly lower with probiotic consumption (MD=-0.98mmol/L; 95% CI: -1.17, 0.78, p<0.00001), with moderate but insignificant heterogeneity noted. Insignificant changes between the groups were also noted for HbA1c and other secondary outcomes.
    CONCLUSIONS: A moderate hypoglycaemic effect of probiotics, with a significantly lower FBG was noted. Findings on HbA1c, anti-inflammatory and anti-oxidative effects of probiotics in the clinical setting, however, remain inconsistent. The findings imply the need for well-designed clinical studies to further assess the potential beneficial effects of probiotics in management of T2DM.
