Abstract Objectives: Artificial sweeteners provide the sweetness of sugar without calories. Since from discovery, safety of artificial sweeteners has been controversial as they directly or indirectly link to induce carcinogenic and genotoxic risks. Hence the present study was undertaken to compare the diabetogenic and mutagenic potential of most widely using artificial sweeteners; aspartame, acesulfame-K, and sucralose. Methods: Diabetic potential is assessed by ascending repeated dose study in which acceptable daily intake (ADI) dose of artificial sweeteners after converting human dose to animal dose using a standard reference table and administered up to 13 weeks with 3 different phases in an ascending manner on experimental rats. Mutagenic potential was accessed by Ames test with and without metabolic activation using Salmonella typhimurium strains TA 97 and TA1535. Results: At ADI doses between 0-3 weeks, no significant changes but after 13 weeks significant increase was observed in the levels of fasting blood glucose, glycated haemoglobin, total cholesterol, triglyceride, LDL and VLDL in all artificial sweetener groups. Sucralose showed comparatively less increase which was supported by histology reports. In Ames mutagenic assay aspartame, acesulfame-K and sucralose gave negative results. Conclusion: Aspartame, acesulfame-K and sucralose were found to exhibit diabetogenic effect at higher dose levels but they were safer to use at ADI doses and non mutagenic compounds. Comparatively sucralose is safer than aspartame and acesulfame-K. Hence these artificial sweeteners should be used with caution and over usage is not appreciated.

BACKGROUND: Sucralose is a high intensity artificial sweetener sucralose and chemically known as 1,6-dichloro-1,6-dideoxy-β-D-fructofuranosyl-4-chloro-4-deoxy-α-D-galactopyranoside. It is used as a sweetener and flavour enhancer in foods and beverages. Due to its high stability at wider temperatures and pH, made its applicability in various food products throughout the world. As per Joint FAO/WHO Expert Group on Food Additives (JECFA) in 1990, the daily intake of sucralose is 0-15 mg/kg body weight. The literature reports suggest that sucralose has a possible health threat due to the presence of chlorine groups, thereby leading to the several illnesses. The growing interest on the use of SUC in the foods, makes it necessary in developing a fast, reliable, cost effective and reproducible analytical method to determine SUC in food samples. The detection of sucralose and other carbohydrates like fructose, glucose and sucrose is a challenging task owing to its: (i) unavailability of the charged functions and (ii) lack of absorption of strong chromophoric nature in the UV region. Therefore, separation of non-absorbing neutral molecules needs a careful procedure with the suitable electrolyte systems. METHODOLOGY: An indirect UV detection capillary electrophoretic method is described for the separation of sucralose in different food samples. It was achieved by nucleophile substitution (SN2) in the presence of amine as background electrolytes. The morpholine buffer showed good buffering capacity in terms of migration time (< 8.0 min) and baseline stability when compared to other amine buffers (ethylamine, piperidine, triethylamine). The analytical applications of proposed method showed by recovery percentages of sucralose in real and spiked samples on intra and inter-day basis at optimum experimental conditions of 0.2 M buffer concentration and pH 12.0 at 230 nm UV detection. RESULTS: The selection of BGE, UV detection wavelength, buffer concentration, buffer pH, cassette temperature and applied voltage were optimized to enhance the sensitivity and selectivity of the separation method. Recoveries obtained were ranging from 96.87 to 98.82 % for real samples and 94.45 to 98.06 % for spiked samples respectively. Linearity was studied in the range of 2-10 mM, and showed a correlation coefficients of 0.9942 with LOD and LOQ found to be 0.3804 mg L-1 and 1.5215 mg L-1 with % RSD (n = 5) ± 1.27 and 1.19 % with respect to migration time and peak area. Furthermore, to better understand the separation of sucralose with amine buffers were investigated computationally using HOMO-LUMO calculations. The obtained results showed that the band gap decreases in the presence of amine moiety irrespective of its nature. CONCLUSION: In the study, novel background electrolytic system was successfully applied to separate sucralose using indirect UV detector with capillary electrophoresis. The FT-IR results confirmed that the interaction of sucralose with different amine buffers to better understand the separation chemistry behind sucralose and amine complexes. Moreover, computational results indicate that the direction of charge transfer from the amine functionality to the glucofuranosyl ring in each amine derivative of sucralose confirms the strong interaction between sucralose and amines, which led in the baseline separation of sucralose in different food samples.

Mutagenic Effects

Mexedrone, α-PVP and α-PHP are synthetic cathinones. They can be considered amphetamine-like substances with a stimulating effect. Actually, studies showing their impact on DNA are totally absent. Therefore, in order to fill this gap, aim of the present work was to evaluate their mutagenicity on TK6 cells. On the basis of cytotoxicity and cytostasis results, we selected the concentrations (35–100 µM) to be used in the further analysis. We used the micronucleus (MN) as indicator of genetic damage and analyzed the MNi frequency fold increase by flow cytometry. Mexedrone demonstrated its mutagenic potential contrary to the other two compounds; we then proceeded by repeating the analyzes in the presence of extrinsic metabolic activation in order to check if it was possible to totally exclude the mutagenic capacity for α-PVP and α-PHP. The results demonstrated instead the mutagenicity of their metabolites. We then evaluated reactive oxygen species (ROS) induction as a possible mechanism at the basis of the highlighted effects but the results did not show a statistically significant increase in ROS levels for any of the tested substances. Anyway, our outcomes emphasize the importance of mutagenicity evaluation for a complete assessment of the risk associated with synthetic cathinones exposure.

Abstract Aim The study aimed to investigate the associations between glycaemic control after acute pancreatitis and gastrointestinal motility, using plasma motilin concentration and gastroparesis cardinal symptom index score as proxies. Methods This cross-sectional study recruited a total of 93 individuals after acute pancreatitis. Gastroparesis cardinal index scores, demographic and anthropometric factors, as well as pancreatitis-related factors were analysed. Fasting venous blood was collected to measure motilin, glycated haemoglobin, and fasting blood glucose. Linear regression analyses were conducted to investigate the associations between glycaemic control and gastrointestinal motility in unadjusted and adjusted models. Results Motilin was significantly higher in individuals with diabetes across all adjusted models, with the highest ß-coefficient (95% confidence interval) of 588.89 (138.50, 1039.28); P=0.010. Fasting blood glucose was significantly associated with motilin across all models, with the highest ß-coefficient (95% confidence interval) of 156.30 (55.49, 257.10); P=0.002. Glycated haemoglobin was significantly associated with motilin in one adjusted model with ß-coefficient (95% confidence interval) of 18.78 (1.53, 36.02); P=0.033. Gastroparesis cardinal symptom index was not significantly associated with any measure of glycaemic control. Conclusions Diabetes in individuals after acute pancreatitis appears to be characterised by elevated plasma motilin but not gastroparesis cardinal symptom index. The role of motilin in this setting warrants further investigations.

The use of nutritional interventions for managing diabetes is one of the effective strategies aimed at reducing the global prevalence of the condition, which is on the rise. Almonds are the most consumed tree nut and they are known to be rich sources of protein, monounsaturated fatty acids, essential minerals, and dietary fibre. Therefore, the aim of this review was to evaluate the effects of almonds on gut microbiota, glycometabolism, and inflammatory parameters in patients with type 2 diabetes. Methods: This systematic review and meta-analysis was carried out according to the preferred reporting items for systematic review and meta-analysis (PRISMA). EBSCOhost, which encompasses the Health Sciences Research Databases; Google Scholar; EMBASE; and the reference lists of articles were searched based on population, intervention, control, outcome, and study (PICOS) framework. Searches were carried out from database inception until 1 August 2021 based on medical subject headings (MesH) and synonyms. The meta-analysis was carried out with the Review Manager (RevMan) 5.3 software. Results: Nine randomised studies were included in the systematic review and eight were used for the meta-analysis. The results would suggest that almond-based diets have significant effects in promoting the growth of short-chain fatty acid (SCFA)-producing gut microbiota. Furthermore, the meta-analysis showed that almond-based diets were effective in significantly lowering (p < 0.05) glycated haemoglobin (HbA1c) levels and body mass index (BMI) in patients with type 2 diabetes. However, it was also found that the effects of almonds were not significant (p > 0.05) in relation to fasting blood glucose, 2 h postprandial blood glucose, inflammatory markers (C-reactive protein and Tumour necrosis factor α, TNF-α), glucagon-like peptide-1 (GLP-1), homeostatic model assessment of insulin resistance (HOMA–IR), and fasting insulin. The biological mechanisms responsible for the outcomes observed in this review in relation to reduction in HbA1c and BMI may be based on the nutrient composition of almonds and the biological effects, including the high fibre content and the low glycaemic index profile. Conclusion: The findings of this systematic review and meta-analysis have shown that almond-based diets may be effective in promoting short-chain fatty acid-producing bacteria and lowering glycated haemoglobin and body mass index in patients with type 2 diabetes compared with control. However, the effects of almonds were not significant (p > 0.05) with respect to fasting blood glucose, 2 h postprandial blood glucose, inflammatory markers (C-reactive protein and TNF-α), GLP-1, HOMA–IR, and fasting insulin.

No-caloric sweeteners, such as aspartame, are widely used in various food and beverages to prevent the increasing rates of obesity and diabetes mellitus, acting as tools in helping control caloric intake. Aspartame is a methyl ester of a dipeptide used as a synthetic nonnutritive sweetener in over 90 countries worldwide in over 6000 products. It was first approved by the US Food and Drug Administration (FDA) in 1981. Aspartame is metabolized to phenylalanine, aspartic acid, and methanol. these metabolites have some health risks specially on PKU (Phenyl Ketone Urea) patients who can’t metabolize the amino acid phenyl alanine. This study aims to investigate the health effects of aspartame on Balb-c mice. 16 Balb-c mice were given physiological solution by oral gavage(control) and the study groups were given the recommended ADI (Acceptable Daily Intake) for mice (ADI = 250mg/kg/body weight) of Aspartame diluted in water for 15days, 30days. Glucose blood level, lipid profile, marker enzymes (ALT.AST.ALP, γGT) and uric acid were determined at the end of the experiment. The results of this study show that oral administration of aspartame (250mg/kg body weight) was correlated to a significant increase in the lipid profile, fasting blood glucose and some marker enzymes and this increase is time related.

The clinical aspects and anatomopathological patterns of 150 postmenopausal women were studied using the progestogen challenge test. An endometrial biopsy was obtained and submitted to the progestogen test. A histopathological analysis of the uterine mucosa from women with a positive progestogen test revealed that the endometrium was active in 44 percent of cases and atrophic or inactive in 56 percent. In contrast, among women with a negative response, the endometrium was atrophic in 94 percent of cases and active in 6 percent. Analysis of clinical aspects did not show significant differences between groups in terms of age; age at menarche and at menopause; fasting blood glucose levels; or body mass. However, postmenopausal time was significantly shorter for women with a positive test, with a correlation between postmenopausal time of one to two years and test positivity. The progestogen challenge test for the detection of atrophic endometrium presented 78.57 percent sensitivity, 77.05 percent specificity, 44 percent positive predictive value, and 94 percent negative predictive value. Thus, when negative, the test is highly valuable, indicating the presence of atrophic endometrium in 94 percent of cases. False-negative results occurred in only 6 percent of the subjects, with no case of hyperplasia detected. However, when the response to the test was positive, the endometrium was atrophic in 56 percent of the cases. We suggest that, in order to avoid invasive procedures, the progestogen challenge test be combined with other methods such as transvaginal ultrasonography.

An environmentally friendly technique has been developed to produce metal nanoparticles using green synthesis methods. In this study, silver nanostructures were synthesized using different sugar substitutes and artificial sweeteners as green reducing agents in an aqueous solution at low temperature. The main ingredients (such as maltodextrin, sucrose, saccharin, and sucralose) of the artificial sweeteners acting as reducing agents were used to reduce Ag+ ions to Ag0. The pH of the solution was controlled during synthesis through the addition of sodium hydroxide (NaOH) to increase the strength of the reducing agents by converting nonreducing sugars to reducing ones and consequently increasing the rate of silver nanoparticle formation. The size and morphology of the synthesized nanostructures were characterized by transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). The formation of nanostructures during the course of the reactions was investigated by UV-visible (UV-vis) spectroscopy characterization of an aliquot of sample at specific intervals. The function of each artificial sweetener and corresponding ingredients as a reducing agent and capping agent was investigated by Fourier-transform infrared spectroscopy (FTIR) and mass spectrometry (MS).
