Alyami HH, Al-Hariri MT. Synergistic Effects of Nigella sativa and Exercise on Diabetic Profiles: A Systematic Review. Diabetes Ther 2023; 14:467-478. [PMID: 36645572 PMCID: PMC9841958 DOI: 10.1007/s13300-022-01362-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 12/23/2022] [Indexed: 01/17/2023] Open
Abstract
Individually, Nigella sativa (NS) and physical training interventions have been shown to be effective preventive and therapeutic strategies for diabetes mellitus. However, the effect of these in combination on bioindicators of diabetes has not yet been evaluated; there is little information available in the literature. A systematic review was therefore performed to assess any mutually potentiating impacts of NS and physical training interventions in diabetic subjects. A search was performed on this topic in the PubMed, CINAHL, Google Scholar and Web of Science databases for randomised, quasi-randomised or non-randomised controlled trials, studies with factorial or single-cohort pre-post designs, case series as well as case reports. The search terms encompassed various combinations of the following: "exercise", "training", "physical activity", "NS", "treadmill", "swimming", "Thymoquinone", "Nigellone", "caraway oil" and "black seeds". Two reviewers screened the abstracts of 202 identified publications according to predetermined inclusion criteria-i.e. papers published from 2009 onwards in the English language, studies on human or animal subjects, and the assessment of diabetic bioindicators following the combined administration of NS and exercise regimens in comparison with just one of these interventions or against controls. Despite the rich data available regarding the effect of both interventions separately, two human studies and two animal studies were ultimately included in the review. However, the benefit of combined administration of NS and exercise regimens on glycemic and lipidemic control was much more obvious compared to exercise alone. In conclusion, these findings suggested that combined administration of NS and exercise regimens could be used as an effective adjuvant for oral antidiabetic drugs in diabetes control.

Abstract
This present study investigated the antioxidative and antidiabetic properties of kolaviron by analysing its inhibitory effect on key metabolic activities linked to T2D, in vitro and ex vivo. Kolaviron significantly inhibited α-glucosidase and α-amylase activities, and intestinal glucose absorption dose-dependently, while promoting muscle glucose uptake. Induction of oxidative pancreatic injury significantly depleted glutathione level, superoxide dismutase, catalase, and ATPase activities, while elevating malondialdehyde and nitric oxide levels, acetylcholinesterase and chymotrypsin activities. These levels and activities were significantly reversed in tissues treated with kolaviron. Kolaviron depleted oxidative-induced metabolites, with concomitant restoration of oxidative-depleted metabolites. It also inactivated oxidative-induced ascorbate and aldarate metabolism, pentose and glucuronate interconversions, fructose and mannose metabolism, amino sugar and nucleotide sugar metabolism, and arginine and proline metabolism, while reactivating selenocompound metabolism. These results depict the antidiabetic properties of kolaviron as indicated by its ability to attenuate oxidative-induced enzyme activities and dysregulated metabolisms, and modulated the enzyme activities linked to hyperglycaemia.

Effect of Carica papaya on IRS-1/Akt Signaling Mechanisms in High-Fat-Diet-Streptozotocin-Induced Type 2 Diabetic Experimental Rats: A Mechanistic Approach. Nutrients 2022; 14:nu14194181. [PMID: 36235831 PMCID: PMC9573020 DOI: 10.3390/nu14194181] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 09/29/2022] [Accepted: 10/04/2022] [Indexed: 11/17/2022] Open
Abstract
Despite rigorous endeavors, existing attempts to handle type 2 diabetes (T2DM) are still a long way off, as a substantial number of patients do not meet therapeutic targets. Insulin resistance in skeletal muscle is discerned as a forerunner in the pathogenesis of T2DM and can be detected years before its progress. Studies have revealed the antidiabetic properties of Carica papaya (C. papaya), but its molecular mechanism on insulin receptor substrate-1 (IRS-1)/Akt signaling mechanisms is not yet known. The present study aimed to evaluate the role of C. papaya on IRS1 and Akt in high-fat-diet-streptozotocin-induced type 2 diabetic rats and also to analyze the bioactive compounds of C. papaya against IRS-1 and Akt via in silico analysis. Ethanolic extract of the leaves of C. papaya (600 mg/kg of body weight) was given daily for 45 days postinduction of T2DM up to the end of the study. Gluconeogenic enzymes, glycolytic enzymes, gene expression, and immunohistochemical analysis of IRS-1 and Akt in skeletal muscle were evaluated. C. papaya treatment regulated the levels of gluconeogenic and glycolytic enzymes and the levels of IRS-1 and Akt in skeletal muscle of type 2 diabetic animals. In silico studies showed that trans-ferulic acid had the greatest hit rate against the protein targets IRS-1 and Akt. C. papaya restored the normoglycemic effect in diabetic skeletal muscle by accelerating the expression of IRS-1 and Akt.

Abstract
Resistance training has shown the potential to contribute to better glycemic control in people with Type 1 Diabetes (T1D), however, there are contradictory results in this regard and a need to clarify the effects of isolated resistance training on glycemic control in T1D. The aim was to verify the effects of resistance training on the glycemic control of people with T1D. Original articles were selected, randomized and non-randomized clinical trials that aimed to verify chronic responses, through the concentrations of glycated hemoglobin (HbA1c), to a structured program of resistance exercise in the glycemia of patients with T1D. The following databases were searched; MEDLINE, PubMed, Web of Science, Scopus, ScienceDirect, LILACS, and SciELO. Five studies were included in the review. A reduction in HbA1c was observed (SMD = -0.568 ± 0.165 [95% CI = -0.891 to -0.246]; p = 0.001; I2 = 82%) in patients undergoing resistance training, when compared to the control group (SMD = 1.006 ± 0.181 [95% CI = 0.653 to 1.360]; p <0.001). Two studies, with children and adolescents and longer interventions, demonstrated a significant reduction in HbA1c, increased strength, and an improved lipid profile. Resistance training was efficient for assisting in glycemic control in people with T1D and should be incorporated in treatment plans.

Abstract
BACKGROUND: Exercise is the main pillar in Type 2 Diabetes Mellitus (T2DM) management. The mechanism of glucose uptake mediated by exercise is different from insulin, and this mechanism is not disturbed in T2DM. One of the mechanisms is through the activation of 5’AMP-activated protein kinase (AMPK). AMPK also regulates the glucose transporter 4 (GLUT4) expression. Effect various types of exercise to AMPK α2 and GLUT-4 of the skeletal muscle still limited.
AIM: This study aims to determine the effect of various physical training on the expression of Ampk α2 and Glut 4 in skeletal muscle of T2DM rats.
METHODS: This study used stored skeletal muscles of 25 T2DM Wistar rats. Previously, the rats were divided into groups of K1 (control, not given exercise), K2 (moderate continuous training), K3 (severe continuous training), K4 (slow interval training), and K5 (fast interval training). Running on a treadmill frequency 3 times a week for 8 weeks. The relative expression of Ampk α2 and Glut 4 were assessed using Real Time-PCR and were compared among the groups using the Livak formula.
RESULTS: Moderate intensity continuous training increased Ampk α2 and Glut 4 expression by 1.45 and 2.39 times, respectively. Severe intensity continuous training increased the expression of Ampk α2 and Glut 4 by 1.55 and 2.56 times, respectively. Slow interval training increased the expression of Ampk α2 and Glut 4 by 4.41 and 3.76 times, respectively. The expression of Ampk α2 and Glut4 in fast interval training was 4.56 and 4.79 times more than control.
CONCLUSION: Continuous and interval training increase Ampk α2 and Glut 4 expression. The fast interval training showed the highest expression of Ampk α2 and Glut 4.

Abstract
The antidiabetic effect of l-leucine has been attributed to its modulatory effect on glucose uptake and lipid metabolism in muscles. However, there is a dearth on its effect on glucose metabolism in muscles. Thus, the present study investigated the effect of l-leucine - stimulated glucose uptake on glucose metabolism, dysregulated lipid metabolic pathways, redox and bioenergetic homeostasis, and proteolysis in isolated psoas muscle from Sprague Dawley male rats. Isolated psoas muscles were incubated with l-leucine (30-240 μg/mL) in the presence of 11.1 mMol glucose at 37 ˚C for 2 h. Muscles incubated in only glucose served as the control, while muscles not incubated in l-leucine and/or glucose served as the normal control. Metformin (6.04 mM) was used as the standard antidiabetic drug. Incubation with l-leucine caused a significant increase in muscle glucose uptake, with an elevation of glutathione levels, superoxide dismutase, catalase, E-NTPDase and 5'nucleotidase activities. It also led to the depletion of malondialdehyde and nitric oxide levels, ATPase, chymotrypsin, acetylcholinesterase, glycogen phosphorylase, glucose-6-phosphatase, fructose-1,6-bisphosphatase and lipase activities. There was an alteration in lipid metabolites, with concomitant activation of glycerolipid metabolism, fatty acid metabolism, and fatty acid elongation in mitochondria in the glucose-incubated muscle (negative control). Incubation with l-leucine reversed these alterations, and concomitantly deactivated the pathways. These results indicate that l-leucine-enhanced muscle glucose uptake involves improved redox and bioenergetic homeostasis, with concomitant suppressed proteolytic, glycogenolytic and gluconeogenetic activities, while modulating glucose - lipid metabolic switch.

Abstract
Background:
Limited studies have been carried out with prednisone (PRED) in treatment by
glucose intolerant individuals, even in this model the animals presented low blood glucose levels at
adulthood, by the high regenerative capacity of β-cell.
Objective:
The aim was to evaluate the effects of the treatment of PRED in mild diabetes on biochemical
and immunological biomarkers.
Methods:
Rats were randomly divided into four groups: control (C), treated control C+PRED (treatment
of 1.25 mg/Kg/day PRED); diabetic DM (mild diabetes) and treated diabetic DM+PRED (treatment
with same dose as C+PRED group). Untreated groups received vehicle, adjusted volume to body
weight. The treatment lasted 21 days and measured body weight, food and water intake, and glycemia
weekly. In the 3rd week, the Oral Glucose Tolerance Test (OGTT) and the Insulin Tolerance Test (ITT)
was performed. On the last day, the rats were killed and the blood was collected for biochemical analyzes,
leukogram and immunoglobulin G levels.
Results:
There was a significant decrease in body weight in mild diabetes; however, the treatment in
diabetic groups increased food intake, glycemia, and the number of total leukocytes, lymphocytes and
neutrophils. On the other hand, it decreased the levels of triglycerides, high-density and very lowdensity
lipoproteins. In addition, diabetic groups showed glucose intolerance and mild insulin resistance,
confirming that this model induces glucose intolerant in adult life.
Conclusion:
The results showed that the use of prednisone is not recommended for glucose intolerant
individuals and should be replaced in order to not to aggravate this condition.
