Neurodegenerative diseases such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis cause damage and gradual loss of neurons affecting the central nervous system. Neurodegenerative diseases are most commonly seen in the ageing process. Ageing causes increased reactive oxygen species and decreased mitochondrial ATP generation, resulting in redox imbalance and oxidative stress.

Metformin, a widely used first-line anti-diabetic therapy for the treatment of type-2 diabetes, has been shown to lower hyperglycemia levels in the blood by enhancing insulin actions. For several decades this drug has been used globally to successfully control hyperglycemia. Lactic acidosis has been shown to be a major adverse effect of metformin in some type-2 diabetic patients, but several studies suggest that it is a typically well-tolerated and safe drug in most patients.

Increased hyperglycemia due to uncontrolled diabetes is the major cause of secondary diabetic complications such as retinopathy, neuropathy, nephropathy, and cardiovascular diseases. Although it is well known that increased oxidative stress, activation of the polyol pathway, protein kinase C and increased generation of advanced glycation end products could contribute to the development of diabetic complications, recent studies implicated the role of innate immunity and its related inflammatory responses in the pathophysiology of secondary diabetic complications. Increased activation of oxidative stress signaling could regulate NLRP3 inflammasome-mediated innate immune responses as well as NF-κB signalosome-mediated pro-inflammatory responses.

The spectrum allocation in any auctioned wireless service primarily depends upon the necessity and the usage of licensed primary users (PUs) of a certain band of frequencies. These frequencies are utilized by the PUs as per their needs and requirements. When the allocated spectrum is not being utilized in the full efficient manner, the unused spectrum is treated by the PUs as white space without believing much in the concept of spectrum scarcity.
