The use of honey in the control of hyperglycemia in patients with type 2 diabetes mellitus is a current option being explored globally. Honey bees which are named in Latin as Apis, use the collected nectar from plants to produce honey after regurgitation and digestion of nectar. Carbohydrate constitutes about 80% of the components of honey. It incl...

Cyclophosphamide (CYP) is a potent DNA-interactive anticancer drug; however, its clinical drawbacks are chiefly associated with induction of oxidative multi-organ toxicity. Sitagliptin (STG) is an antidiabetic dipeptidyl peptidase-4 inhibitor drug with antioxidant efficacy. Herein, we have explored whether STG could abrogate the CYP-induced oxidati...

There has been an increased prevalence of end-stage renal disease (ESRD) in the last decades. This can be attributed to high incidence of chronic diseases such as metabolic disorders, diabetes and hypertension. These diseases are often associated with ESRD, which requires regular dialysis and may later necessitate renal transplantation. The increas...
Article

Cancer cells generate reactive oxygen species (ROS) resulting from mitochondrial dysfunction, stimulation of oncogenes, abnormal metabolism, and aggravated inflammatory activities. Available evidence also suggests that cancer cells depend on intrinsic ROS level for proliferation and survival. Both physiological and pathophysiological roles have bee...

Honey is a natural substance with many medicinal properties, including antibacterial, hepatoprotective, hypoglycemic, antioxidant and antihypertensive effects. It reduces hyperglycemia in diabetic rats and humans. However, the mechanism(s) of its hypoglycemic effect remain(s) unknown. Honey comprises many constituents, making it difficult to ascert...
Article

The primary aim of the current management of diabetes mellitus is to achieve and/or maintain a glycated hemoglobin level of ≤6.5%. However, recent evidence indicates that intensive treatment of hyperglycemia is characterized by increased weight gain, severe hypoglycemia and higher mortality. Besides, evidence suggests that it is difficult to achiev...

The global prevalence of chronic diseases such as diabetes mellitus, hypertension, atherosclerosis, cancer and Alzheimer's disease is on the rise. These diseases, which constitute the major causes of death globally, are associated with oxidative stress. Oxidative stress is defined as an "imbalance between oxidants and antioxidants in favor of the o...

Evidence shows that honey improves glycemic control in diabetes mellitus. Besides its hypoglycemic effect, studies indicate that honey ameliorates lipid abnormalities in rats and humans with diabetes. The majority of these studies do not examine the mechanisms by which honey ameliorates glycemic and/or lipid derangements. The gut microbiota is now...
