Radiocontrast media (RCM) are necessary for many diagnostic procedures such as arteriography, percutaneous coronary intervention (PCI), and computed tomography. Contrast-induced acute kidney injury (CI-AKI) is the third most common cause of hospital-associated kidney damage accounting for 10-25% of cases worldwide. The mechanisms of contrast-induced renal impairment are not entirely known, but diminished renal hemodynamics, inflammatory responses, and direct cytotoxicity have been hypothesized. The purpose of this study was to investigate the mechanisms of direct cytotoxicity observed in HK-2 cells following treatment with diatrizoic acid (DA) and to determine the source of this damage. Mitochondrial function, endoplasmic reticulum (ER) stress, oxidative …

Role Of Iron In Ethanol Derived Hepatic Stress, Jesse A. Thornton

Chronic alcohol abuse is the third leading cause of preventable death in the United States. Ethanol metabolism causes liver injury through alterations in hepatic metabolic state, redox status, and acetaldehyde adduct formations. Increased iron absorption is associated with chronic ethanol consumption and may play a role in ethanol induced oxidative stress. We tested the hypothesis that normal labile iron in the liver plays a role in ethanol related pathological stress, using C57/Bl6 mice pair-fed Lieber-DeCarli liquid ethanol diets for 11 and 22 weeks. Normal iron group mice received 55mg/kg iron as ferric citrate, whereas the low iron groups received 5mg/kg. …
Evaluation Of The Role Of Oxidative Stress, Inflammation And Apoptosis In The Pulmonary And The Hepatic Toxicity Induced By Cerium Oxide Nanoparticles Following Intratracheal Instillation In Male Sprague-Dawley Rats, Siva Krishna Nalabotu

The field of nanotechnology is rapidly progressing with potential applications in the automobile, healthcare, electronics, cosmetics, textiles, information technology, and environmental sectors. Nanomaterials are engineered structures with at least one dimension of 100 nanometers or less. With increased applications of nanotechnology, there are increased chances of exposure to manufactured nanomaterials. Recent reports on the toxicity of engineered nanomaterials have given scientific and regulatory agencies concerns over the safety of nanomaterials. Specifically, the Organization for Economic Co-operation and Development (OECD) has identified fourteen high priority nanomaterials for study. Cerium oxide (CeO2) nanoparticles are one among the high priority group. Recent data …
