Abstract
Molybdenum is an essential trace element for human health and survival, with molybdenum-containing enzymes catalysing multiple reactions in the metabolism of purines, aldehydes, and sulfur-containing amino acids. Recommended daily intakes vary globally, with molybdenum primarily sourced through the diet, and supplementation is not common. Although the benefits of molybdenum as an anti-diabetic and antioxidant inducer have been reported in the literature, there are conflicting data on the benefits of molybdenum for chronic diseases. Overexposure and deficiency can result in adverse health outcomes and mortality, although physiological doses remain largely unexplored in relation to human health. The lack of knowledge surrounding molybdenum intake and the role it plays in physiology is compounded during pregnancy. As pregnancy progresses, micronutrient demand increases, and diet is an established factor in programming gestational outcomes and maternal health. This review summarises the current literature concerning varied recommendations on molybdenum intake, the role of molybdenum and molybdoenzymes in physiology, and the contribution these play in gestational outcomes.

Abstract
Molybdenum has been found to be associated with metabolic disorders. However, the relationship between molybdenum and metabolic syndrome (MetS) is still unclear. A large case-control study was conducted in a Chinese population from the baseline of Ezhou-Shenzhen cohort. A total of 5356 subjects were included with 2678 MetS and 2678 controls matched by sex and age (±2 years). Medians (IQRs) of plasma molybdenum concentrations were 1.24 μg/L for MetS cases and 1.46 μg/L for controls. After adjustment for multiple covariates, the odds ratio (OR) and 95% confidence intervals (CIs) for MetS were 1.00 (reference), 0.71 (0.59-0.84), 0.56 (0.46-0.68), and 0.47 (0.39-0.58) across quartiles of plasma molybdenum, and per SD increment of log-transformed molybdenum was associated with a 23% lower risk of MetS. In the spline analysis, the risk of MetS and its components decreased steeply with increasing molybdenum and followed by a plateau when the cutoff point was observed around 2.0 μg/L. The dose-dependent relationship of molybdenum with MetS remained consistent when considering other essential elements in the Bayesian kernel machine regression (BKMR) model. In our study, higher plasma molybdenum was significantly associated with a lower risk of MetS, as well as its components, in a dose-response manner.

Streptozotocin (STZ)-Induced Diabetes Affects Tissue Trace Element Content in Rats in a Dose-Dependent Manner. Biol Trace Elem Res 2020; 198:567-574.

Abstract
The objective of the present study was investigation of tissue trace element distribution in a streptozotocin model of DM1 in rats. DM1 was modeled in 2-month-old male Wistar rats (n = 30) using intraperitoneal injection of 45 mg/kg b.w. (STZ1) and 55 mg/kg b.w. streptozotocin (STZ2), whereas control animals were injected with physiological saline. The rats were subjected to oral glucose tolerance test (OGTT) and HbA1c level assessment at day 14. At day 30, blood serum, liver, kidney, and heart samples were collected for tissue trace element assessment using inductively coupled plasma mass spectrometry (ICP-MS). STZ-treated rats were characterized by lack of significant weight gain and elevated HbA1c and blood glucose levels. ICP-MS analysis demonstrated a dose-dependent accumulation of Cu, Mn, Mo, and Se levels in the liver. Correspondingly, the dose-dependent increase in renal Cu, Mn, V, and Zn levels was significant, whereas the observed trend for kidney V and Mo accumulation was nearly significant. The patterns of trace element content in the myocardium of STZ-exposed rats were quite different from those observed for liver and kidney. Only cardiac Zn content was characterized by a significant decrease. Serum Co, Cr, Cu, Se, V, and Mo levels were characterized by a significant decrease in response to STZ-induced diabetes. Generally, the obtained data demonstrate that diabetes is associated with altered copper, manganese, molybdenum, chromium, and vanadium handling. In turn, only altered Zn status may provide a link to diabetic cardiotoxicity. However, the particular mechanisms of both impaired metal handling in STZ diabetes and their potential anti-diabetic activity require further investigation.

Abstract
Banana is an extensively cultivated plant worldwide, mainly for its fruit, while its ancillary product, the banana pseudostem, is consumed as a vegetable and is highly recommended for diabetics in the traditional Indian medicine system. The present study was aimed at elucidating the mechanism of antihyperglycaemia exerted by the ethanol extract of banana pseudostem (EE) and its isolated compounds viz., stigmasterol (C1) and β-sitosterol (C2), in an alloxan-induced diabetic rat model. Diabetic rats which were administered with C1, C2 and EE (100 and 200 mg per kg b. wt.) for 4 weeks showed reduced levels of fasting blood glucose and reversal of abnormalities in serum/urine protein, urea and creatinine in diabetic rats compared to the diabetic control group of rats. Diabetic symptoms such as polyphagia, polydipsia, polyuria, urine glucose and reduced body weight were ameliorated in the diabetic group of rats fed with EE, C1 and C2 (100 mg per kg b. wt., once daily) for 28 days. The levels of insulin and Hb were also increased, while the HbA1c level was reduced. The altered activities of hepatic marker enzymes viz., aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP); glycolytic enzyme (hexokinase); shunt enzyme (glucose-6-phosphate dehydrogenase); gluconeogenic enzymes (glucose-6-phosphatase, fructose-1,6-bisphosphatase and lactate dehydrogenase) and pyruvate kinase were significantly reverted to normal levels by the administration of EE, C1 and C2. In addition, increased levels of hepatic glycogen and glycogen synthase and the corresponding decrease of glycogen phosphorylase activity in diabetic rats illustrated the antihyperglycaemic potential of EE and its components. The histological observations revealed a marked regeneration of the β-cells in the drug treated diabetic rats. These findings suggest that EE might exert its antidiabetic potential in the presence of C1 and C2, attributable to the enhanced glycolytic activity, besides increasing the hepatic glucose utilization in diabetic rats by stimulating insulin secretion from the remnant β-cells.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Oral administration of alcoholic decoctions of Aristolochia ringens is used extensively by Traditional Medicine Practitioners (TMP) of Yoruba heritage in South west, Nigeria for the management of diabetes and its associated complications. AIM OF THE STUDY To assess the potentials of root ethanolic extract of Aristolochia ringens V. (REAR) in the management of diabetes using chemical induced experimental animal model. MATERIALS AND METHODS Qualitative and quantitative analyses were carried out to elucidate chemical constituents of the REAR extract using phytochemical analyses and gas chromatography-mass spectrometry (GC-MS) technique. Streptozotocin (STZ)-induced diabetic rats were orally administered with 75, 150 and 300mg/kg body weight of the REAR, once a day and the blood glucose (GLU) levels were monitored for 14 days. Mechanisms of GLU lowering effect were investigated by performing oral glucose tolerance test (OGTT) and modulation of diabetes associated biomarkers including hepatic glycogen (GLY), GLU, alpha amylase (αAMY) and glucose-6-phosphate dehydrogenase (GPDH) by the extract. RESULTS Extraction from A. ringens roots using ethanol/water (70/30) yielded 10.25% w/w REAR extract. Preliminary phytochemical profiling of REAR extract revealed the presence of flavonoids (23.03%), phenols (19.15%), alkaloids (16.13%), tannins (4.21%), saponins (1.44%) and GC-MS analyses showed that bulk of the extract was constituted by aristolone (92.3%). Oral administration of 300mg/kg b. wt. REAR extract caused significant reduction (>90%) in hyperglycemia to normal GLU level (≤ 120mg/dl) after 11 days of treatment. Lower doses of 75 and 150mg/kg b. wt. caused similar effect after 13 days. The extract also normalized postprandial GLU to baseline level within 90-120min. Also, GLY concentrations and GPDH activity were significantly increased, whereas GLU levels and αAMY activity were reduced in the liver of diabetic rats treated with REAR extract compared to values in non-treated diabetic group. CONCLUSION These findings revealed that ethanolic extract from A. ringens root possess antihyperglycemic activity and the data established its usage in folkloric decoctions for management of diabetes.

Abstract
This study investigates the ameliorative effect of vescalagin (VES) isolated from Pink wax apple fruit on hepatic insulin resistance and abnormal carbohydrate metabolism in high-fructose diet (HFD)-induced hyperglycemic rats. The results show that in HFD rats, VES significantly reduced the values of the area under the curve for glucose in an oral glucose tolerance test and the homeostasis model assessment of insulin resistance index. VES significantly enhanced the activity of hepatic antioxidant enzymes while reducing thiobarbituric acid-reactive substances in HFD rats. Western blot assay revealed that VES reduced hepatic protein expression involved in inflammation pathways while up-regulating expression of hepatic insulin signaling-related proteins. Moreover, VES up-regulated the expression of hepatic glycogen synthase and hepatic glycolysis-related proteins while down-regulating hepatic gluconeogenesis-related proteins in HFD rats. This study suggests some therapeutic potential of VES in preventing the progression of diabetes mellitus.

Abstract
BACKGROUND S. surattense is widely used in Siddha medicine for various ailments. OBJECTIVE The aim was to evaluate the impact of alcoholic leaf-extract of S. surattense on mitochondrial enzymes in streptozotocin (STZ) induced diabetic rats and to study the in vitro muscle glucose uptake activity on L6 myotubes. MATERIALS AND METHODS The male albino Wistar rats were randomly divided into five groups of six animals each. Diabetes was induced by intraperitoneal injection of STZ (40 mg/kg body weight). After being confirmed the diabetic rats were treated with alcoholic leaf-extract of S. surattense (100 mg/kg body weight) for 45 days. The biochemical estimations (liver mitochondrial enzymes, antioxidants, thiobarbituric acid reactive substances [TBARS]) and histopathological studies were performed. Further, the in vitro muscle glucose uptake activity in L6 myotubes and messenger RNA (mRNA) expression of glucose transporter-4 (GLUT-4) was performed. RESULTS In diabetic rats, the activities of liver mitochondrial enzymes were found to be significantly lowered. The mitochondrial TBARS level increased, whereas the activities/level of enzymatic and non-enzymatic antioxidants decreased in diabetic rats. Administration of S. surattense to diabetic rats significantly reversed the above parameters toward normalcy. Furthermore in diabetic rats, the histopathological studies showed growth of adipose tissue and shrinkage of islets in the pancreas, liver showed fatty change with mild inflammation of portal triad, and kidney showed messangial capillary proliferation of glomeruli and fatty infiltration of tubules. Treatment with S. surattense brought back these changes to near normalcy. The extract was analyzed for in vitro muscle glucose uptake activity in L6 myotubes and mRNA expression of GLUT-4 by semi-quantitative reverse transcriptase-polymerase chain reaction. One nano gram per millilitre of S. surattense leaf-extract gave 115% glucose uptake on L6 myotubes. It also showed elevated levels of GLUT-4 mRNA transcripts, when compared with control cells. CONCLUSION These studies strongly support the anti-diabetic nature of S. surattense.

Abstract
The vanadyl(IV) adenine complex; [VO(Adn)2]⋅SO4; was synthesized and characterized. The molar conductivity of this complex was measured in DMSO solution that showed an electrolyte nature. Spectroscopic investigation of the green solid complex studied here indicate that the adenine acts as a bidentate ligand, coordinated to vanadyl(IV) ions through the nitrogen atoms N7 and nitrogen atom of amino group. Thus, from the results presented the vanadyl(IV) complex has square pyramid geometry. Further characterizations using thermal analyses and scanning electron techniques was useful. The aim of this paper was to introduce a new drug model for the diabetic complications by synthesized a novel mononuclear vanadyl(IV) adenine complex to mimic insulin action and reducing blood sugar level. The antidiabetic ability of this complex was investigated in STZ-induced diabetic mice. The results suggested that VO(IV)/adenine complex has antidiabetic activity, it improved the lipid profile, it improved liver and kidney functions, also it ameliorated insulin hormone and blood glucose levels. The vanadyl(IV) complex possesses an antioxidant activity and this was clear through studying SOD, CAT, MDA, GSH and methionine synthase. The current results support the therapeutic potentiality of vanadyl(IV)/adenine complex for the management and treatment of diabetes.

Abstract
UNLABELLED Although the gene expression patterns during the development of diabetic nephropathy have been studied in both rodent models and humans, only a small portion of the mRNAs expressed in the mesangium or in glomerular cells has been characterized. In the present study we report larger groups of transcripts displaying significant expression modulation in glomerular cells obtained from the early phase of diabetic nephropathy. METHODS We used 12-week-old female db/db mice, a rodent model of type 2 diabetes, and their non-diabetic db/m litter-mates. Glomerular cells were obtained from the kidneys of mice by laser capture microdissection. Preparation of cRNA and target hybridization were performed according to the Affymetrix GeneChip Eukaryotic Small Sample Target Labeling Assay Protocol (Version II). The gene expression profile was determined by the mouse Expression Set 430A GeneChip. RESULTS By comparison between db/m and db/db mice, 649 probes that increased in expression with the induction of diabetes and 340 probes that decreased in diabetic kidneys were identified. Although some of these genes have previously been shown to play an important role in diabetic nephropathy, the large majority of them have never been demonstrated to be regulated during the development of nephropathy. CONCLUSIONS Although the precise involvement of these genes in diabetic nephropathy remains to be clarified, the data presented here will aid in the identification of genes that play a significant role in this pathological condition.

Abstract
FL83B mouse hepatocytes were treated with tumor necrosis factor-α (TNF-α) to induce insulin resistance to investigate the effect of a wax apple aqueous extract (WAE) in insulin-resistant mouse hepatocytes. The uptake of 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxyglucose (2 NBDG), a fluorescent D-glucose derivative, was performed, and the metabolism of carbohydrates was evaluated by examining the expression of glycogenesis or glycolysis-related proteins in insulin-resistant hepatocytes. The results show that WAE significantly improves the uptake of glucose and enhances glycogen content in insulin-resistant FL83B mouse hepatocytes. The results from Western blot analysis also reveal that WAE increases the expression of glycogen synthase (GS), hexokinase (HXK), glucose-6-phosphate dehydrogenase (G6PD), phosphofructokinase (PFK) and aldolase in TNF-α treated cells, indicating that WAE may ameliorate glucose metabolism by promoting glycogen synthesis and the glycolysis pathways in insulin-resistant FL83B mouse hepatocytes.

Abstract
Zygophyllum album has been mentioned in Tunisian system of folk medicine to be of value in the treatment of diabetes mellitus. The present study was designed to investigate the possible antihyperglycemic effects of ethanolic extracts of the whole plant of Z. album on blood glucose, plasma insulin, serum lipids and hepatic glycogen and metabolism enzymes of carbohydrate in streptozotocin (STZ)-induced diabetic mice. Administration of the ethanolic extract from plant (100 and 300 mg/kg body weight) for 14 days resulted in significant reduction in plasma glucose, cholesterol, triglycerides, low-density lipoprotein, very-low-density liprotein, hepatic glucokinase and glycogen in STZ diabetic mice. In addition to that, significant increase in plasma high-density lipoprotein, hepatic phosphofructokinase and glucose-6 phosphate dehydrogenase was observed in STZ diabetic mice. After administration of the ethanolic extract, the increased level of plasma insulin is not significant in diabetic mice. In conclusion, the present results showed that the ethanolic extract of Z. album possesses significant antihyperglycemic and antihyperlipidemic effects in experimental model of diabetes mellitus.

Abstract
The effect of N-benzoyl-d-phenylalanine (NBDP) and metformin combination treatment on liver lipids and lipid peroxidation markers was studied in neonatal streptozotocin (nSTZ) diabetic rats. Oral administration of NBDP (50, 100 and 200 mg/kg body weight) and metformin (500 mg/kg body weight) for 6 weeks significantly reduced the elevated blood glucose, liver cholesterol, triglycerides, free fatty acids and phospholipids. The combination treatment also caused a significant decrease in hepatic hydroxymethyl glutaryl-coenzyme A reductase, Thiobarbituric Acid Reactive Substances (TBARS) and significant increase in reduced glutathione levels. The results show that NBDP and metformin improve the hepatic lipid profile and antioxidant status in nSTZ diabetic rats. Combination treatment was more effective than either drug alone.

Abstract
The purpose of this study was to investigate the effects of daily oral administration of aqueous solution of Boerhaavia diffusa L. leaf extract (BLEt) (200 mg/kg) for 4 weeks on blood glucose concentration and hepatic enzymes in normal and alloxan induced diabetic rats. A significant decrease in blood glucose and significant increase in plasma insulin levels were observed in normal and diabetic rats treated with BLEt. Treatment with BLEt resulted in a significant reduction of glycosylated haemoglobin and an increase in total haemoglobin level. The activities of the hepatic enzymes such as hexokinase was significantly increased and glucose-6-phosphatase, fructose-1,6-bisphosphatase were significantly decreased by the administration of BLEt in normal and diabetic rats. An oral glucose tolerance test (OGTT) was also performed in the same groups, in which there was a significant improvement in glucose tolerance in rats treated with BLEt. A comparison was made between the action of BLEt and antidiabetic drug-glibenclamide (600 microg/kg). The effect of BLEt was more prominent when compared to glibenclamide.

Abstract
The present study was designed to investigate the antihyperglycemic effects of aqueous and ethanolic extracts from Gongronema latifolium leaves on glucose and glycogen metabolism in livers of non-diabetic and streptozotocin-induced diabetic rats. To investigate the effects of aqueous or ethanolic leaf extracts of G. latifolium, non-diabetic and STZ diabetic rats were treated twice daily (100 mg/Kg) for two weeks. Diabetic rats showed a significant decrease in the activities of hepatic hexokinase (HK), phosphofructokinase (PFK) and glucose-6-phosphate dehydrogenase (G6PDH) and an increase in glucokinase (GK) activity. The levels of hepatic glycogen and glucose were also increased in diabetic rats. However, there were no significant differences in the activities of glucose-6-phosphatase (G6Pase) in treated and untreated diabetic rats. The ethanolic extract significantly increased the activities of HK (p<0.01), PFK (p<0.001) and G6PDH (p<0.01) in diabetic rats, decreased the activity of GK (p<0.05) and the levels of hepatic glycogen (p<0.01) and both hepatic (p<0.001) and blood glucose (40%). The aqueous extract of G. latifolium was only able to significantly increase the activities of HK and decrease the activities of GK but did not produce any significant change in the hepatic glycogen and both hepatic and blood glucose content of diabetic rats. Our data show that the ethanolic extract from G. latifolium leaves has antihyperglycemic potency, which is thought to be mediated through the activation of HK, PFK, G6PDH and inhibition of GK in the liver. The ethanolic extract is under further investigation to determine the chemical structure of the active compound(s) and its/their mechanism of action.

Abstract
We profiled the expression of 5,760 clones from a kidney subtraction library in the kidneys of three groups of NOD mice: nondiabetic, new-onset, and long-term diabetic. A total of 27 genes had lower expression and 1 gene (Gpx3) had higher expression in the new-onset diabetic mice compared with nondiabetic control NOD mice (P < 0.001). Similarly, 19 of the above 27 genes and 7 additional genes had higher expression and the Gpx3 gene had lower expression in long-term diabetic mice compared with controls (P < 0.001). Interestingly, only three genes may be different between new-onset and long-term diabetic mice (P < 0.0004). These genes are from diverse functional groups, including oxidative phosphorylation, free radical neutralization, channels, pumps, lipid processing, transcription and translation machinery, protein trafficking, constitutive protein processing, and immune function. The majority of these genes fall into four signaling pathways: insulin, transforming growth factor-beta, tumor necrosis factor-alpha, and peroxisome proliferator-activated receptor. The most significant expression change was found for the stearoyl-coenzyme A desaturase 1 (SCD1) gene (P < 10(-7)). The lower expression levels of the SCD1 gene in both diabetic groups compared with controls were further confirmed by Northern blot analysis and immunohistochemistry.

Abstract
In the 21st century, patients suffering from diabetes mellitus (DM), a lifestyle-related disease, will increase more than in the 20th century. DM is threatening because of the development of many severe secondary complications, including atherosclerosis, microangiopathy, renal dysfunction and failure, cardiac abnormalities, diabetic retinopathy, and ocular disorders. Generally, DM is classified as either insulin-dependent type 1 or noninsulin-dependent type 2 DM. Type 1 DM is treated only by daily insulin injections; type 2 DM is treated by several types of synthetic therapeutic substances together with a controlled diet and physical exercise. Even with these measures, the daily necessity for several insulin injections can be painful both physically and mentally, whereas the synthetic therapeutic substances used over the long term often have side effects. For those reasons, the creation and development of a new class of pharmaceuticals for treatment of DM in the 21st century would be extremely desirable. In the last half of the 20th century, investigations of the relationships among diseases and micronutrients, such as iron, copper, zinc, and selenium, have been numerous. Research into the development of metallopharmaceuticals involving the platinum-containing anticancer drug, cisplatin, and the gold-containing rheumatoid arthritis drug, auranofin, has also been widespread. Such important findings prompted us to develop therapeutic reagents based on a new concept to replace either insulin injections or the use of synthetic drugs. After many trials, we noticed that vanadium might be very useful in the treatment of DM. Before the discovery of insulin by Banting and Best in 1921 and its clinical trial for treating DM, the findings in 1899, in which orally administered sodium vanadate (NaVO(3)) was reported to improve human DM, gave us the idea to use vanadium to treat DM. However, it has taken a long time to obtain a scientific explanation as to why the metal ion exhibits insulin-mimetic or blood-glucose lowering effects in in vitro and in vivo experiments. After investigations from many perspectives involving biochemistry and bioinorganic chemistry, vanadyl sulfate (VOSO(4)) and its complexes with several types of ligands have been proposed as useful for treating DM in experimental diabetic animals. On the basis of a mechanistic study, this article reports on recent progress regarding the development of antidiabetic vanadyl complexes, emphasizing that the vanadyl ion and its complexes are effective not only in treating or relieving both types of DM but also in preventing the onset of DM.

Abstract
Gongronema latifolium is a rainforest plant, which has been traditionally used in the South Eastern part of Nigeria for the management of diabetes. The effects of oral administration of aqueous and ethanolic G. latifolium leaf extracts for 2 weeks on streptozotocin-induced diabetic rats were investigated. Both extracts were shown to significantly increase the activity of superoxide dismutase and the level of reduced glutathione. The aqueous extract further increased the activity of glutathione reductase while the ethanolic extract caused a significant increase in the activity of glutathione peroxidase and glucose-6-phosphate dehydrogenase and a significant decrease in lipid peroxidation. These results suggest that the extracts from G. latifolium leaves could exert their antidiabetic activities through their antioxidant properties.
