Vitamin D levels and lipid profiles in patients with polycystic ovary syndrome

BackgroundPolycystic ovary syndrome (PCOS) is the most common endocrine disorder among women. Dyslipidemia is a prevalent metabolic abnormality in individuals with PCOS. Moreover, vitamin D deficiency is widespread across all societal strata, with a particularly heightened prevalence observed in patients afflicted with PCOS. The present study aimed to investigate the level of vitamin D and its correlation with lipid profiles in Iranian women diagnosed with PCOS.MethodsThis cross-sectional study was carried out at the PCOS and infertility clinic of Arash Women’s Hospital in Tehran. The study encompassed the medical records of PCOS patients who attended the clinic from March 2021 to December 2023. All patients underwent blood tests, which included assessments of fasting blood sugar levels, lipid profiles, and 25-hydroxyvitamin D (25(OH)D) levels. The investigation focused on evaluating the relationship between vitamin D levels and lipid profiles. Statistical analyses, including the chi-square test and Spearman’s correlation coefficient, were employed to analyze the data.ResultsA total of 1004 women diagnosed with PCOS were included in the study. The age range of the participants was 14 to 46 years. The majority of the participants had a body mass index (BMI) within the normal range (n = 555, 55.3%). The median vitamin D level among the participants was 26.00 (IQR: 19.00–34.00). The relationship between vitamin D levels and lipid profile parameters was assessed, revealing no significant correlation between vitamin D levels and low-density lipoprotein (LDL) (r = 0.021, p = 0.505), high-density lipoprotein (HDL) (r = 0.011, p = 0.719), or triglyceride (TG) (r = -0.026, p = 0.417) levels, both in non-adjusted and age-adjusted analyses.ConclusionAccording to the present study, there was no significant correlation between serum 25(OH)D deficiency and elevated TG or LDL levels or decreased HDL levels in PCOS patients. Nevertheless, further prospective studies are needed to determine whether there is a causal relationship between vitamin D deficiency and lipid profile alterations, specifically among PCOS patients.

Perception and coping mechanisms of patients with diabetes mellitus during the COVID-19 pandemic in Ibadan, Nigeria.

The 2019 coronavirus disease (COVID-19) ushered in a period of fear and uncertainty, resulting in structural instability across the globe. Vulnerable individuals, such as patients with diabetes mellitus, are predispose to have adverse effects and complications of COVID-19 when infected. We explored the perception of diabetes mellitus patients during the COVID-19 pandemic and their coping mechanisms at the University College Hospital, Ibadan. We employed an exploratory qualitative study design to explore diabetes mellitus patients' perceptions and coping mechanisms during the COVID-19 pandemic. A purposive sampling technique was used to recruit 32 participants (2 health professionals and 30 diabetes mellitus patients). In-depth interviews were used to collect the data from the participants. All the recorded audio data were transcribed verbatim and exported to NVivo software for thematic data analyses. Most diabetes mellitus patients were not fearful of the pandemic but were optimistic that it would not affect their health. Mechanisms such as the usage of herbal medicines and adherence to COVID-19 precautionary measures were noticed among patients. The study also revealed that the hospital's coping mechanism during the COVID-19 pandemic include prolonged appointments, limiting the number of patients attended per clinic day, and the provision of telehealth service. Patients in our study utilised negative coping mechanisms such as reduced drug dosages, subscriptions to cheaper drug brands, and reliance on religious institutions rather than a clinic for health instructions. The study has shown that diabetes mellitus patients were not fearful of the COVID-19 pandemic. The utilisation of telehealth, encouragement of daily monitoring of sugar levels, provision of avenues for a medication review, and adherence to the safety protocols were coping mechanisms employed by the health system and diabetes mellitus patients. We recommend that the government and other healthcare stakeholders reinforce the resilience of diabetes mellitus patients by alleviating their health burdens during the pandemic. This could be done by subsidizing the prices of drugs, tests, and consultation fees for patients with diabetes mellitus. Also, more efforts should be made to elevate the health system through the reduction in waiting and appointment times in the diabetes clinic and employing more health personnel in the clinic.

Association of KCNJ11 gene (rs5219) polymorphism with HOMA-IR & HOMA B values in type 2 diabetes mellitus in India: A case-control study

Objectives Type 2 diabetes mellitus (T2DM) is a complex illness that results from either insulin resistance or insufficient insulin, which raises blood sugar levels. Numerous genes interact to influence the secretion of insulin. A gene of great interest is KCNJ11 of subfamily-J, member 11, which functions as an inwardly rectifying ATP-sensitive potassium (KATP) channel in pancreatic beta cells and is involved in glucose-stimulated insulin release. Material & Methods The present case-control study attempts to delineate the genetic impact of KCNJ11 (rs5219) gene polymorphism on the risk of T2DM in the Indian population. It involves 55 patients with type 2 diabetes (fasting plasma glucose of >126 mg/dl, 2-h glucose of >200 mg/dl, or HbA1c level of >6.4%) and 55 healthy controls (fasting plasma glucose of <100 mg/dl, 2-h glucose of <140 mg/dl, or HbA1c level of <6.4%). polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) was used to study KCNJ11 polymorphism through a standard protocol. Enzyme Linked Immunosorbent Assay (ELISA) was used to estimate serum Insulin levels. HOMA-IR & HOMA-β values were calculated. Statistical analysis was done using t-test, Chi-Square test, and One-way analysis of variance (ANOVA) test. Results Serum insulin levels and HOMA-IR values were significantly decreased in cases than in the control group. Logistic regression analysis showed that the frequency of KK genotype in T2DM individuals (21.8%) was higher than the control group (9%) (p = 0.01). Frequency of K allele (38%) in patients was higher than the control group (18%) (p = 0.001). The K allele risk in diabetic patients was 9.9 times higher as compared to controls (p = 0.001, OR 9.9, 95%Cl 0.036–0.36). Homeostatic model assessment β (HOMA-β) values of KK genotype (59.9±27.8315) were lower than that of EK (76.8±33.23) and EE (127.9±44.59) genotypes (p < 0.001). Conclusion The presence of KCNJ11 (rs 5219) gene polymorphism shows a noteworthy correlation with the likelihood of developing T2DM among the North Indian population. K allele is more likely to be present in individuals with T2DM than the control group. Moreover, HOMA-β values of those with the KK genotype were found to be lower than the individuals having EK and EE genotypes.

Growth Differentiation Factor -15 (GDF-15) Levels in Diabetic Conditions: Animal Model

Diabetes mellitus (DM) is a disease characterized by increased blood sugar levels, consisting of Diabetes Mellitus type I (DMT1) and Diabetes Mellitus type II (DMT2). Chronic increases in blood glucose levels will cause oxidative stress through the accumulation of Reactive Oxygen Species (ROS). Oxidative stress will induce the secretion of pro- and anti-inflammatory mediators, including Growth Differentiation Factor-15 (GDF-15). GDF-15 levels can be used to predict the risk and progression of DM disease. In exploring diabetes, several studies were carried out on experimental animal models of diabetes, both T1DM and 2DMT models. This research is an experimental study with a Pre and Post-Test Control Group Design approach using rat animals divided into four groups (I=Control group; II=Alloxan group; III=Streptozotocin group and IV=Streptozotocin and high fat diet group) with the aim of to see the levels of Growth Differentiation Factor-15 (GDF-15) in diabetic animal model. Based on this research, there was an increase in levels of Growth Differentiation Factor-15 (GDF-15) before and after diabetic animal model in the Streptozotocin group P value 0.010; and Streptozotocin with a High Fat Diet group with P value of 0.043 (significance value P < 0.05).

Quantitative Proteomics Analysis of ABA- and GA3-Treated Malbec Berries Reveals Insights into H2O2 Scavenging and Anthocyanin Dynamics.

Abscisic acid (ABA) and gibberellic acid (GA3) are regulators of fruit color and sugar levels, and the application of these hormones is a common practice in commercial vineyards dedicated to the production of table grapes. However, the effects of exogenous ABA and GA3 on wine cultivars remain unclear. We investigated the impact of ABA and GA3 application on Malbec grapevine berries across three developmental stages. We found similar patterns of berry total anthocyanin accumulation induced by both treatments, closely associated with berry H2O2 levels. Quantitative proteomics from berry skins revealed that ABA and GA3 positively modulated antioxidant defense proteins, mitigating H2O2. Consequently, proteins involved in phenylpropanoid biosynthesis were downregulated, leading to decreased anthocyanin content at the almost ripe stage, particularly petunidin-3-G and peonidin-3-G. Additionally, we noted increased levels of the non-anthocyanins E-viniferin and quercetin in the treated berries, which may enhance H2O2 scavenging at the almost ripe stage. Using a linear mixed-effects model, we found statistical significance for fixed effects including the berry H2O2 and sugar contents, demonstrating their roles in anthocyanin accumulation. In conclusion, our findings suggest a common molecular mechanism by which ABA and GA3 influence berry H2O2 content, ultimately impacting anthocyanin dynamics during ripening.

A comparative analysis of red and white dragon fruit pulp and juice characteristics.

To ascertain their potential applications in the food industry, dragon fruit varieties, namely H. undatus and H. polyrhizus, were thoroughly analyzed for their physical, nutritional, and phytochemical properties. The focus was on pulp and juice, emphasizing color, mineral content, proximate analysis, and phytochemical constituents. Red flesh dragon fruit displayed a bright pink color, a slightly smaller length (9.1 cm), and a larger diameter (8.3 cm) compared to white flesh dragon fruit (9.9 cm length, 7.53 cm diameter). Red flesh dragon fruit also exhibited higher circumference and weight. White flesh dragon fruit demonstrated superior juice yield (36.23 %) compared to red flesh dragon fruit (35.28 %). Red flesh dragon fruit had higher levels of total sugar (8.45 %), protein (1.36 %), and ascorbic acid (19.83 mg/100g) in its pulp. It also showed elevated mineral content of calcium, magnesium, and phosphorus. Conversely, white flesh dragon fruit had higher fat content (0.65 %) and carbohydrate content (9.76 %) in its pulp. White flesh dragon fruit displayed brighter color characteristics with higher L*, a*, and b* values. Phytochemical analysis revealed the presence of betacyanin in red flesh dragon fruit (30.87 mg/100g) but not in white flesh dragon fruit. Red flesh dragon fruit exhibited significantly higher total phenolic content in pulp (49.67 mg GA/100g) and juice (41.25 mg GA/100g) than white flesh dragon fruit. These findings highlight substantial differences (P < lt; 0.05) between red and white flesh dragon fruit in physical, nutritional, and phytochemical aspects, offering valuable insights for their incorporation into diverse food products, such as beverages and ice cream.

Effect of Organic and Industrial Fertilizers on Reducing Sugar, Specific Gravity, Dry Matter and Starch Composition of Fresh Harvested Irish Potato Varieties in Musanze District Rwanda

Potatoes for use in industrial processing must have a low reducing sugar concentration. This study investigates the impact of organic and synthetic fertilizers on the composition of Irish potato cultivars’ reducing sugar, specific gravity, dry matter, and starch. The research was conducted at Busogo Farm in Rwanda, using randomized complete block designs in seasons 2021 B and 2022 A with rate of ten tones per hectare under the doses of 100%, 50%, and 0% and three hundred kilograms per hector under the dose of 100%, 50% and 0% respectively for farmyard manure and NPK 17.17.17. Results showed significant effects of season and treatment on reducing sugar levels in potatoes. Twihaze and Kirundo varieties recorded high glucose (0.09%), while Gisubizo variety in control, recorded low glucose (0.01%). Additionally, the analysis of variance showed that Irish potato varieties with low to moderate and moderate to high glucose contents, respectively, experienced extremely significant (p 0.001) effects of farmyard manure and NPK on glucose content for the seasons 2021 B and 2022 A. The application of inorganic and organic fertilizers had a significant impact (p 0.05) on dry matter in seasons B and A, according to the analysis of variance. Additionally, the results demonstrated extremely significant (p<0.01) differences in specific gravity and starch in both seasons, with Kinigi variety having higher values of dry matter, specific gravity, and starch content in season B and A, respectively, of 24.58, 1.10, and 18.59%. Season 2022 A’s high decreasing sugar levels were caused by meteorological conditions brought on by the soil’s high moisture content as well as the maturity of the tubers. Due to its low level of reducing sugar, Gikungu, Kirundo, and Kinigi are excellent for chips whereas Twihaze variety is advised for boiling cooking methods.

Evolution of dietary patterns in Flanders: an ecological trend study on best-selling cookbook recipes (2008–2018) and their correlation with household purchases

BackgroundWith rising obesity rates in Western societies, analyzing changes in dietary patterns is paramount. While nutritional surveys have been informative, traditional cookbooks have historically shed light on national cuisines and its changes. Despite the growing popularity of online platforms for food information, cookbooks might still reflect prevalent dietary trends and the diets people follow. This study examined (1) the changes in nutritional content and food group usage in the best-selling cookbooks from 2008 to 2018, and (2) the correlation between the food groups in these cookbooks and dietary patterns (inferred from household purchases) over the same timeframe.MethodsAn exploratory ecological study was conducted on 20 main course recipes of each of the five best-selling cookbooks in Flanders annually between 2008 and 2018. Trends in macronutrients and food group usage in these recipes were analyzed using generalized linear models. Additionally, these trends were compared to household purchase data in Flanders using correlation matrices.ResultsOur results reveal a rising trend towards the use of plant-based ingredients and meat alternatives in cookbooks over the period 2008–2018. There was an increase in the usage of vegetables, nuts & seeds, and cheese. Conversely, there was a decline in the usage of meat, sugar & sweeteners, alcohol, and dairy (all p-values < 0.05). In terms of macronutrient content, there was an upswing in carbohydrate, fibre, and sugar levels, while the total fat content showed a decrease (all p-values < 0.05). The levels of protein and saturated fat remained consistent over time. Notably, shifts in plant-based and animal-based food group preferences in popular cookbook recipes align with the trends seen in actual household purchases of these food groups (all p-values < 0.05).ConclusionThese findings indicate that cookbook content evolves over time, potentially reflecting shifts in population dietary patterns. Future research is needed to (1) determine any causative link between cookbooks and any causative link between cookbooks and (2) the potential for cookbooks to aid in health promotion.

Phenolic, amino acids, and fatty acids profiles and the nutritional properties in the fresh and dried fruits of black rosehip (Rosa pimpinellifolia L.)

Recently, increased attention has been paid to the raw materials of plants as a source of biologically active substances. Black rosehip (Rosa pimpinellifolia L.) fruits could be a good resource for potential functional components in the food, cosmetic and pharmaceutical industries. Also, drying can influence the composition of heat-sensitive phytochemicals. However, less attention is given to comparing black rosehip bioactive compounds particularly compositions of fatty acid, amino acids, and phenolic content in fresh and dried fruits. So in this study, the amino acid constituents (by amino acid analyzer), fatty acids (by GC–MS), mineral elements (by atomic absorption spectrometer), antioxidant (by DPPH) and phenolic compounds (by HPLC) present in fresh and dried fruits of black rosehip naturally grown in Iran were comprehensively investigated. The results showed that dried fruits had a lower level moisture by 51.55%, and a higher level of total phenolic compounds and total sugar by 786.20 mg GAE/100 g and 15.77 g/100 g, respectively. Chlorogenic acid and gallic acid were the major phenolic compounds (109.3 mg/g). Whilst, linoleic acid, oleic acid, and arachidic acid (85.34%) were the most dominant fatty acids. The most dominant amino acids were glutamic acid, phenylalanine, and arginine (29.41 g/100 g). Also, Fe and Mn as micro-elements were the most dominant elements. In general, the results illustrated the potentials and differences of black rosehip fruits grown in the Arasbaran region as promising resources for food sources, pharmaceutics, cosmetics, and breeding programs. Also, these findings confirm that black rosehip fruits contain significant amounts of secondary metabolites that may positively affect human health.

Genetics of glucose homeostasis in pregnancy and postpartum.

Pregnancy is accompanied by maternal metabolic adaptations to ensure fetal growth and development, including insulin resistance, which occurs primarily during the second and third trimesters of pregnancy, and a decrease in fasting blood sugar levels over the course of pregnancy. Glucose-related traits are regulated by genetic and environmental factors and modulated by physiological variations throughout the life course. We addressed the hypothesis that there are both overlaps and differences between genetic variants associated with glycaemia-related traits during and outside of pregnancy. Genome-wide SNP data were used to identify genetic variations associated with glycaemia-related traits measured during an OGTT performed at ~28 weeks' gestation in 8067 participants in the Hyperglycaemia and Adverse Pregnancy Outcome (HAPO) Study. Associations outside of pregnancy were determined in 3977 individuals who also participated in the HAPO Follow-Up Study at 11-14 years postpartum. A Bayesian classification algorithm was used to determine whether SNPs associated with fasting and 2 h glucose and fasting C-peptide during pregnancy had a pregnancy-predominant effect vs a similar effect during pregnancy and postpartum. SNPs in six loci (GCKR, G6PC2, GCK, PPP1R3B, PCSK1 and MTNR1B) were significantly associated with fasting glucose during pregnancy, while SNPs in CDKAL1 and MTNR1B were associated with 1 h glucose and SNPs in MTNR1B and HKDC1 were associated with 2 h glucose. Variants in CDKAL1 and MTNR1B were associated with insulin secretion during pregnancy. Variants in multiple loci were associated with fasting C-peptide during pregnancy, including GCKR, IQSEC1, PPP1R3B, IGF1 and BACE2. GCKR and BACE2 were associated with 1 h C-peptide and GCKR, IQSEC1 and BACE2 with insulin sensitivity during pregnancy. The associations of MTNR1B with 2 h glucose, BACE2 with fasting and 1 h C-peptide and insulin sensitivity, and IQSEC1 with fasting C-peptide and insulin sensitivity that we identified during pregnancy have not been previously reported in non-pregnancy cohorts. The Bayesian classification algorithm demonstrated that the magnitude of effect of the lead SNP was greater during pregnancy compared with 11-14 years postpartum in PCSK1 and PPP1R3B with fasting glucose, in three loci, including MTNR1B, with 2 h glucose, and in six loci, including IGF1, with fasting C-peptide. Our findings support the hypothesis that there are both overlaps and differences between the genetic architecture of glycaemia-related traits during and outside of pregnancy. Genetic variants at several loci, including PCSK1, PPP1R3B, MTNR1B and IGF1, appear to influence glycaemic regulation in a unique fashion during pregnancy. Future studies in larger cohorts will be needed to replicate the present findings, fully characterise the genetics of maternal glycaemia during pregnancy and determine similarities to and differences from the non-gravid state.

Nutritional Composition and Fungi Isolates Associated with Moringa Oleifera Leaves and Seeds

Moringa oleifera (miracle tree) as it is popularly called, has been found useful both medicinally and economically. Moringa oleifera is the most widely cultivated species of the monogeneric family, the Moringaceae, which is indigenous to South Asia. This fast-growing plant is a highly valued and cultivated one in the tropics and sub-tropics. With its high nutritive values, every part of the tree is suitable for either nutritional or commercial purposes. The leaves of this tree are worthy of special attention. The leaves are rich in minerals, vitamins, and other essential phytochemicals. This research is aimed at determining the nutritional composition and fungi isolates associated with Moringa oleifera. The Sabaraud Dextrose Agar was used to culture for pure growth and three microorganisms were isolated which consisted of Aspergillus terreus, Aspergillus niger, and Aspergillus flavus. The nutritional analysis of Moringa oleifera was carried out and its composition includes; crude lipids, crude fiber, moisture, ash, protein, and carbohydrates. They aid in treating digestive problems, reduce cholesterol and immunomodulation benefits, proper growth of the sperm cells, synthesis of DNA and RNA and they help to lower blood pressure. The mineral composition analyzed in Moringa oleifera leaves and seeds constituted zinc, copper, silver, and manganese. The microorganisms isolated produce toxins that cause harm and damage to humans. These toxins can be controlled if post-harvest interventions that reduce aflatoxin include rapid and proper drying, proper transportation and packaging, sorting, cleaning, drying, smoking, post-harvest insect control, and the use of botanicals or synthetic pesticides as storage protectants. The health benefits of Moringa oleifera include, they are anti-inflammatory in nature due to the presence of isothiocyanates, having anti-oxidative properties and protecting against the damaging effects of free radicals present in the body, stabilizing blood sugar levels due to the presence of isothiocyanates. They support brain health and work as neuro-enhancers, they are natural cleansers and help to detoxify the system. They are used as supplements in food to improve the nutritional composition that is lacking in the body.

Evaluation of terpenes rich Hura crepitans extract on glucose regulation and diabetic complications in STZ-induced diabetic rats

The continual increase in global diabetic statistics portends decreased productivity and life spans, thus making it a disease of concern requiring more effective and safe therapeutic options. While several reports on antidiabetic plants, including Hura crepitans, are available, there is still a dearth of information on the holistic antidiabetic properties of H. crepitans and its associated complications. This study evaluated the antidiabetic potential of methanolic extract of Hura crepitans using in vitro, in vivo, and in silico approaches. The extract revealed a dose-dependent in vitro effect, with a 47.97 % and 65.34 % decrease in the fasting blood sugar levels of streptozotocin (STZ) induced diabetic rats at 150 and 300 mg/kg BW, respectively. Likewise, the extract increased serum and pancreatic insulin levels, and significantly ameliorated neuronal oxidative stress and inflammation by reducing the expression levels of cholinesterase, NF-κB, and COX-2 in the brain of hyperglycemic rats. Serum dyslipidemia, liver, and kidney biomarker indices, and hematological alterations in diabetic rats were also significantly attenuated by the extract. Several constituents, mainly terpenes, were identified in the extract. To further predict the drug-likeness, pharmacokinetics, and binding properties of the compounds, in silico analysis was conducted. Ergosta-2,24-dien-26-oicacid,18-(acetyloxy)-5,6-epoxy-4, 22-dihydroxy-1-oxo-,delta.-lactone-4.beta., displayed the highest docking scores for acetylcholinesterase, butyrylcholinesterases, alpha-amylase, and nuclear factor-kB with values of −12.4, −10.9, −10.3, and −9.4 kcal/mol, while ergost-25-ene-6,12-dione,3,5-dihydroxy-, (3.beta.,5.alpha.) topped for cyclooxygenase-2 (-9.0 kcal/mol). The top-ranked compounds also presented significant oral drug-likeness, pharmacokinetics, and safety properties. Altogether, our data provide preclinical evidence of the potential of Hura crepitans in ameliorating diabetes and its associated complications.

Analysis of the Effect of Zinc Consumption on the Growth and Development of School Age Children

Zinc is an essential mineral for the health of school-age children even though the body requires only a small amount of it. Children are among those at high risk of zinc deficiency. The aim of this study is to find out the impact of zinc consumption on the growth of school-age children. This research method uses a literature review design by searching for some articles that are relevant to the topic taken to obtain information, then analyzed and presented in a narrative form. The results show that parents who lack knowledge about the importance of zinc for health and are less attentive to this, then children may be deficient in zinc intake. As a result, it affects the child's height, weight, and brain development. When children consume zinc on a regular basis, it can support their growth, effectively deal with stunting, prevent adverse effects on their temperament, maintain the immune system, and synergistically lower blood sugar levels in obese children. In conclusion, there is a positive influence that supports the growth of the child if the need for zinc is met from food as well as supplements and a negative influence when the child consumes less zinc.

Now in this present analytical research world quality by design or design by expert technique is used to get improved method for method validation. This concise review work can guide an analyst to choose most appropriate method for a best analytical method development and validation. This assessment encompasses various analytical methods such as UV Spectrophotometry, High performance liquid chromatography [HPLC], Liquid chromatography – Mass spectrometry (LC-MS), High performance thin layer chromatography (HPTLC) and Ultra performance liquid chromatrography (UPLC) for the estimation of sitagliptin in single and/or in combination.

Vildagliptin promotes diabetic foot ulcer healing through autophagy modulation

The study aimed to investigate the molecular mechanisms underlying the effects of Vildagliptin on the healing of diabetic foot ulcers (DFUs). The research compared patients who received 12 weeks of Vildagliptin treatment to those who did not. Various molecular markers associated with wound healing were measured. Wound fluid samples were collected from DFUs using a filter paper absorption technique, and total RNA was extracted for quantitative real-time PCR (qPCR). The results showed that the autophagy marker NUP62 was significantly downregulated in the Vildagliptin group at week 12 compared to baseline (median expression 0.57 vs. 1.28; P = 0.0234). No significant change was observed in the placebo group (median expression 1.61 vs. 1.48; P = 0.9102). Both groups showed substantial downregulation of RIPK3, a necroptosis marker, at week 12 compared to their respective baselines. In addition to its effects on blood sugar levels, Vildagliptin may promote DFU healing by reducing autophagy in patients with diabetes.

Fabrication of Glucose Fluorescent Aptasensor Based on CdTe Quantum Dots.

Diabetes is a chronic metabolic disease characterized by high blood glucose (or blood sugar) levels, which harms the heart, blood vessels, eyes, kidneys, and nerves over time. So, it is crucial to regularly control glucose concentration in biological fluids to check its targets, reduce unpleasant symptoms of high and low blood sugar, and avoid long-term diabetes complications. This study developed a simple, rapid, sensitive, and cost-effective fluorescence system for glucose determination. The fluorescent Aptasensor was fabricated using cadmium telluride quantum dots (CdTe QDs) modified with thioglycolic acid and functionalized with thiol-glucose-aptamer through ligand exchange. The thiol-glucose-aptamer interacted directly with CdTe QDs, increasing fluorescence intensity. However, it decreased when the target molecules of glucose were introduced. The structural and morphological characteristics of the Aptasensor were confirmed by various analytical methods such as UV-visible spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), atomic force microscopy (AFM), and dynamic light scattering (DLS). According to the typical Stern-Volmer equation, the relationship between fluorescent quenching and target concentration was linear with a detection limit (LOD) of 0.13 ± 1.95 × 10-11 mol L-1 and a relative standard deviation (RSD) of 1.05%. The Aptasensor demonstrated high specificity towards the target and stability over 28 days. Furthermore, it detected glucose in human serum and urine with a recovery rate of up to 99.74%. The results indicate that the fluorescent Aptasensor could be valuable in developing robust sensing technology for low-concentrated analytes.

Ultra-Processed Food Intake and Increased Risk of Obesity: A Narrative Review.

The prevalence of obesity has become a global health concern, with significant impacts on quality of life and mortality rates. Recent research has highlighted the role of ultra-processed foods (UPFs) in driving the obesity epidemic. UPFs undergo extensive processing, often containing high levels of sugars, fats, and additives, while lacking essential nutrients. Studies have linked UPF consumption to obesity and cardiometabolic diseases, underscoring the importance of dietary patterns rich in whole foods. Thus, the aim of this narrative review is to elucidate the correlation between ultra-processed foods and the increased trend of obesity and its related complications. These foods, prevalent in modern diets, contribute to nutritional deficiencies and excessive caloric intake, exacerbating obesity rates. Lifestyle factors such as busy schedules and quick meal management further drive UPF consumption, disrupting hunger regulation and promoting overeating. UPF consumption correlates with adverse health outcomes, including dyslipidemia, hypertension, and insulin resistance. Promoting whole, minimally processed foods and implementing school-based nutrition education programs are crucial steps. Also, numerous challenges exist, including unequal access to healthy foods, the industry's influence, and behavioral barriers to dietary change. Future research should explore innovative approaches, such as nutrigenomics and digital health technologies, to personalize interventions and evaluate policy effectiveness. Collaboration across disciplines and sectors will be vital to develop comprehensive solutions and improve public health outcomes globally.

Impact of Group Reality Therapy on Treatment Adherence and Health Indicators in Patients with Type 2 Diabetes Mellitus: A Randomized Controlled Trial

Background: The use of non-pharmacological therapies is important in reducing the complications and consequences of diabetes. Objectives: This study aimed to determine the effect of group reality therapy on adherence to treatment regimens and health indicators in patients with type 2 diabetes. Methods: This randomized controlled trial was performed on 60 patients with diabetes who were referred to Amir Al-Momenin Hospital in Ahvaz. Patients were randomly assigned to either the intervention group (N = 30) or the control group (N = 30). Both groups completed health indicator tests, questionnaires on demographic and clinical information, perceived adherence to the treatment regimen, and the Perceived Stress Scale. The intervention group received reality therapy training, which consisted of 10 sessions of 45 minutes each (one session per week) over 2 months, delivered through lectures and face-to-face training sessions. The control group received only routine hospital interventions. The collected data were then analyzed using a one-way t-test and one-way analysis of variance (ANOVA). Results: Twenty-seven patients in the intervention group and 27 in the control group completed the study. After analyzing the data, it was revealed that the mean age of the patients in the control group was 55.30 ± 7.95, while it was 51.96 ± 10.55 in the intervention group. Findings showed that scores for the dimensions of adherence to the treatment regimen in the intervention group significantly increased compared to the control group (P &lt; 0.001). Additionally, the mean health indicators in the intervention group showed a significant decrease compared to the control group (P &lt; 0.001). Moreover, the mean blood sugar level of patients in the intervention group decreased from 229.63 ± 98.76 to 123.59 ± 42.03. Likewise, the level of glycosylated hemoglobin and blood cholesterol significantly decreased from 8.19 ± 2.09 to 6.11 ± 1.86 and from 176.52 ± 51.53 to 146.22 ± 34.68, respectively. Conclusions: A reality therapy training program can be effectively used to increase treatment adherence and improve health indicators in patients with type 2 diabetes.

Activation of the yeast Retrograde Response pathway by adaptive laboratory evolution with S-(2-aminoethyl)-L-cysteine reduces ethanol and increases glycerol during winemaking

BackgroundGlobal warming causes an increase in the levels of sugars in grapes and hence in ethanol after wine fermentation. Therefore, alcohol reduction is a major target in modern oenology. Deletion of the MKS1 gene, a negative regulator of the Retrograde Response pathway, in Saccharomyces cerevisiae was reported to increase glycerol and reduce ethanol and acetic acid in wine. This study aimed to obtain mutants with a phenotype similar to that of the MKS1 deletion strain by subjecting commercial S. cerevisiae wine strains to an adaptive laboratory evolution (ALE) experiment with the lysine toxic analogue S-(2-aminoethyl)-L-cysteine (AEC).ResultsIn laboratory-scale wine fermentation, isolated AEC-resistant mutants overproduced glycerol and reduced acetic acid. In some cases, ethanol was also reduced. Whole-genome sequencing revealed point mutations in the Retrograde Response activator Rtg2 and in the homocitrate synthases Lys20 and Lys21. However, only mutations in Rtg2 were responsible for the overactivation of the Retrograde Response pathway and ethanol reduction during vinification. Finally, wine fermentation was scaled up in an experimental cellar for one evolved mutant to confirm laboratory-scale results, and any potential negative sensory impact was ruled out.ConclusionsOverall, we have shown that hyperactivation of the Retrograde Response pathway by ALE with AEC is a valid approach for generating ready-to-use mutants with a desirable phenotype in winemaking.

Engineering the Rhizosphere Microbiome with Plant Growth Promoting Bacteria for Modulation of the Plant Metabolome.

Plant-growth-promoting bacteria (PGPB) have beneficial effects on plants. They can promote growth and enhance plant defense against abiotic stress and disease, and these effects are associated with changes in the plant metabolite profile. The research problem addressed in this study was the impact of inoculation with PGPB on the metabolite profile of Salicornia europaea L. across controlled and field conditions. Salicornia europaea seeds, inoculated with Brevibacterium casei EB3 and Pseudomonas oryzihabitans RL18, were grown in controlled laboratory experiments and in a natural field setting. The metabolite composition of the aboveground tissues was analyzed using GC-MS and UHPLC-MS. PGPB inoculation promoted a reconfiguration in plant metabolism in both environments. Under controlled laboratory conditions, inoculation contributed to increased biomass production and the reinforcement of immune responses by significantly increasing the levels of unsaturated fatty acids, sugars, citric acid, acetic acid, chlorogenic acids, and quercetin. In field conditions, the inoculated plants exhibited a distinct phytochemical profile, with increased glucose, fructose, and phenolic compounds, especially hydroxybenzoic acid, quercetin, and apigenin, alongside decreased unsaturated fatty acids, suggesting higher stress levels. The metabolic response shifted from growth enhancement to stress resistance in the latter context. As a common pattern to both laboratory and field conditions, biopriming induced metabolic reprogramming towards the expression of apigenin, quercetin, formononetin, caffeic acid, and caffeoylquinic acid, metabolites that enhance the plant's tolerance to abiotic and biotic stress. This study unveils the intricate metabolic adaptations of Salicornia europaea under controlled and field conditions, highlighting PGPB's potential to redesign the metabolite profile of the plant. Elevated-stress-related metabolites may fortify plant defense mechanisms, laying the groundwork for stress-resistant crop development through PGPB-based inoculants, especially in saline agriculture.
