A variety of human disorders, e.g., ischemic heart disease, stroke, kidney disease, eventually share the deleterious consequences of a common, hypoxic and oxidative stress pathway. In this review, we utilize recent information on the cellular defense mechanisms against hypoxia and oxidative stress with the hope to propose new therapeutic tools. The hypoxia-inducible factor (HIF) is a key player...

Periodontitis is a common inflammatory disease. It characterized by destruction of the supporting structures teeth and could lead to tooth loss systemic inflammation. Bacteria in inflamed gingival tissue virulence factors are capable entering bloodstream induce response, thus influencing pathological process many diseases, such as cardiovascular diabetes, chronic kidney disease, well liver inju...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

Once thought only as storage for excess nutrients, adipose tissue has been shown to be a dynamic organ implicated in the regulation of many physiological processes. There is emerging evidence supporting differential roles for visceral and subcutaneous white adipose tissue in maintaining health, although how these roles are modulated by the aging process is not clear. However, the proposed benef...

objective(s):atherosclerosis is chronic inflammatory process triggered by oxidative stress. oxidative stress can increase hydrogen peroxide (h2o2)level, which induce atherosclerosis through the processes such as formation of perivascular adipose tissue (pvat), foam cells, and atherosclerotic plaque. antioxidant is needed to control negative effects of oxidative stress. one source of antioxidant...

Background: Due to oxidative stress, hypoxia, and serum deprivation, a large percentage of mesenchymal stem cells (MSCs) die in the early stages of transplantation. The present study aimed to address whether induction or inhibition of autophagy would affect the viability of MSCs after exposure to oxidative stress.Methods: MSCs were isolated from umbilical cord tissue using the Ficoll grad...

Oxidative stress results from a cell or tissue failing to detoxify the free radicals that are produced during metabolic activity. Diabetes is characterized by chronic hyperglycemia that produces dysregulation of cellular metabolism. This review explores the concept that diabetes overloads glucose metabolic pathways, resulting in excess free radical production and oxidative stress. Evidence is p...

Mesenchymal stromal/stem cells (MSCs) are multipotent stem cells present in most fetal and adult tissues. Ex vivo culture-expanded MSCs are being investigated for tissue repair and immune modulation, but their full clinical potential is far from realization. Here we review the role of oxidative stress in MSC biology, as their longevity and functions are affected by oxidative stress. In general,...

Apelin, a peptide hormone, is an endogenous ligand for G protein-coupled receptor and has been shown to be widely expressed in human animal tissues, such as the central nervous system adipose tissue. Recent studies indicate that apelin/APJ involved regulation of multiple physiological pathological processes, it associated with cardiovascular diseases, metabolic disorders, neurological ischemia-...
