Effect of pantoprazole on I-R-induced myocardial injury in diabetic rats targeting inflammatory cytokine release and oxidative stress.

Objectives: To evaluate the pleiotropic potential and underlying mechanism of pantoprazole (PPZ) (common Proton Pump Inhibitors, PPIs) in type 2 diabetes mellitus (T2DM) -associated ischemia/reperfusion (I-R)-induced myocardial infarction which is still uncharted. Whereas some other PPIs have demonstrated their anti-diabetic, antioxidant, and anti-inflammatory potential.

Materials And Methods: We evaluated the potential of coinciding treatment of PPZ (4 mg/kg/po/day for 8 weeks) in Wistar albino rats against STZ (50 mg/kg/IP) induced T2DM model and I-R provoked cardiac infarction model in diabetic and non-diabetic condition.

Minocycline and Doxycycline: More Than Antibiotics.

Minocycline and doxycycline both are second-generation tetracycline antibiotics with similar chemical structures and comparable antibacterial spectrum. Minocycline has also emerged as the tetracycline of choice for multidrug-resistant Acinetobacter baumannii infections, although doxycycline has also shown the activity. Minocycline showed promising results in experimental neurology, which was due to its highly lipophilic nature.

Chronic oral administration of low-dose combination of fenofibrate and rosuvastatin protects the rat heart against experimentally induced acute myocardial infarction.

Fenofibrate and rosuvastatin at low doses might have experimental pleiotropic benefits. This study investigated the combined effect of low doses of fenofibrate and rosuvastatin in isoproterenol-induced experimental myocardial infarction. Rats administered isoproterenol (85 mg/kg/day, s.

Nephroprotective effect of catechin on gentamicin-induced experimental nephrotoxicity.

Background: Gentamicin is an effective aminoglycoside antibiotic employed against severe Gram-negative bacterial infections, but induction of nephrotoxicity limits its frequent clinical use. This study was undertaken to investigate the effect of catechin hydrate on gentamicin-induced nephrotoxicity in rats.

Methods: Rats were administered nephrotoxic dose of gentamicin (100 mg/kg/day, i.

Exploration of pharmacological interventions to prevent isoproterenol-induced myocardial infarction in experimental models.

High incidences of myocardial infarction associated with high morbidity and mortality, are a major concern and economic burden on industrialized nations. Persistent β-adrenergic receptor stimulation with isoproterenol leads to the development of oxidative stress, myocardial inflammation, thrombosis, platelet aggregation and calcium overload, which ultimately cause myocardial infarction. Therapeutic agents that are presently employed for the prevention and management of myocardial infarction are beta-blockers, antithrombotics, thrombolytics, statins, angiotensin converting enzyme inhibitors, angiotensin II type 1 receptor blockers, calcium channel blockers and nitrovasodilators.

Catechin averts experimental diabetes mellitus-induced vascular endothelial structural and functional abnormalities.

Diabetes mellitus is associated with an induction of vascular endothelial dysfunction (VED), an initial event that could lead to the pathogenesis of atherosclerosis and hypertension. Previous studies showed that catechin, a key component of green tea, possesses vascular beneficial effects. We investigated the effect of catechin hydrate in diabetes mellitus-induced experimental vascular endothelial abnormalities (VEA).

Signalling mechanisms involved in renal pathological changes during cisplatin-induced nephropathy.

Context: Cisplatin, a coordination platinum complex, is used as a potential anti-neoplastic agent, having well recognized DNA-damaging property that triggers cell-cycle arrest and cell death in cancer therapy. Beneficial chemotherapeutic actions of cisplatin can be detrimental for kidneys.

Background: Unbound cisplatin gets accumulated in renal tubular cells, leading to cell injury and death.

Green tea catechins: defensive role in cardiovascular disorders.

Green tea, Camellia sinensis (Theaceae), a major source of flavonoids such as catechins, has recently shown multiple cardiovascular health benefits through various experimental and clinical studies. These studies suggest that green tea catechins prevent the incidence of detrimental cardiovascular events, and also lower the cardiovascular mortality rate. Catechins present in green tea have the ability to prevent atherosclerosis, hypertension, endothelial dysfunction, ischemic heart diseases, cardiomyopathy, cardiac hypertrophy and congestive heart failure by decreasing oxidative stress, preventing inflammatory events, reducing platelet aggregation and halting the proliferation of vascular smooth muscle cells.

Pleiotropic antioxidant potential of rosuvastatin in preventing cardiovascular disorders.

Rosuvastatin is a promising synthetic hydrophillic statin which provides potential benefits in reducing cardiovascular risk factors. Rosuvastatin has potent ability to diminish low density lipoprotein, very low density lipoprotein, triglycerides and enhance high density lipoprotein level to manage high cholesterol level and associated cardiovascular diseases. Intriguingly, numerous studies demonstrated that rosuvastatin can reverse the cardiac disorders such as hypertension, atherosclerosis, ischemic heart disease, congestive heart failure and cardiomyopathy by reducing reactive oxygen species mediated oxidative stress.

Diabetes mellitus associated cardiovascular signalling alteration: a need for the revisit.

Diabetes mellitus, a chronic metabolic disorder, is recognized as a root cause of cardiovascular disorders. A long-term and uncontrolled diabetes mellitus coincides with the cardiovascular signalling alteration, resulting in inadequacy of maintaining the cardiovascular physiology. Nitric oxide (NO) is an imperative mediator of cardiovascular physiology as its signalling is known to mediate vasodilatory, anti-platelet, anti-proliferative, and anti-inflammatory actions in vessels.
