Background and Objective: Due to the importance of acute kidney injury associated in patients with sepsis and the impact of various factors on mortality and hospital stay of these patients, this study was conducted to investigate the clinical features and risk factors for acute kidney injury in patients with sepsis. In addition, we examined whether the severity of acute kidney injury affected c...

conclusions pretreatment with epo and application of ipc significantly ameliorated the renal injury induced by bilateral renal ir. however, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. there were no significant differences between pretreatment with epo or application of ipc. materials and methods twenty four male wistar rats were allocated into four exper...

Ischemia time during partial nephrectomy is strongly associated with acute and chronic renal injury. ATP depletion during warm ischemia inhibits ATP-dependent processes, resulting in cell swelling, cytoskeletal breakdown, and cell death. The duration of ischemia tolerated by the kidney depends on the amount of ATP that can be produced with residual substrates and oxygen in the tissue to sustain...

Background: Renal ischemia reperfusion injury may occur in a variety of clinical situations, following a transient drop in total or regional blood flow to the kidney. This study was performed to investigate the protective effects of different antioxidants such as vitamin C, vitamin E, hydrocortisone and combination of these agents against experimental renal ischemia-reperfusion injury....

Autophagy is induced in renal tubular cells during acute kidney injury; however, whether this is protective or injurious remains controversial. We address this question by pharmacologic and genetic blockade of autophagy using mouse models of cisplatin- and ischemia-reperfusion-induced acute kidney injury. Chloroquine, a pharmacological inhibitor of autophagy, blocked autophagic flux and enhance...

Nicotinamide adenine dinucleotide (NAD+ ) homeostasis is constantly compromised due to degradation by NAD+ -dependent enzymes. replenishment supplementation with the precursors nicotinamide mononucleotide (NMN) and riboside (NR) can alleviate this imbalance. However, NMN NR are limited their mild effect on cellular pool need of high doses. Here, we report a synthesis method reduced form (NMNH),...

BACKGROUND Acute kidney injury (AKI) has been recognized as one of the most complex clinical complications in modern medicine, and ischemia/reperfusion (I/R) injury is well-known as a main reason of AKI. In addition, AKI leads to important systemic consequences such as acute lung injury. This study was designed to investigate the role of erythropoietin (EPO) on kidney function makers and tissue...

Objective(s):Acute kidney injury (AKI), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  Renal ischemia-reperfusion, one of the main causes of AKI, is of particular importance in the setting of kidney transplantation. Materials and Methods: Sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

background: renal ischemia reperfusion injury may occur in a variety of clinical situations, following a transient drop in total or regional blood flow to the kidney. this study was performed to investigate the protective effects of different antioxidants such as vitamin c, vitamin e, hydrocortisone and combination of these agents against experimental renal ischemia-reperfusion injury. method:...

Our findings demonstrate the pivotal importance of caspase-3 in regulating renal microvascular dysfunction, fibrogenesis, and long-term impairment after acute kidney injury induced by ischemia-reperfusion injury. Furthermore, this study establishes predominant role peritubular capillary integrity as a major contributor to progressive dysfunction
