Potential of medicinal plants to ameliorate neovascularization activities in diabetes: A systematic review.

Hyperglycemia in diabetes mediates the release of angiogenic factors, oxidative stress, hypoxia, and inflammation, which in turn stimulate angiogenesis. Excessive angiogenesis can cause diabetic retinopathy, diabetic neuropathy, and diabetic nephropathy. All of these complications are debilitating, which may lead to an increased susceptibility to lower-limb amputations due to ulcerations and infections.

Changes in Mitochondrial Epigenome in Type 2 Diabetes Mellitus.

Type 2 Diabetes Mellitus is a major chronic metabolic disorder in public health.
