Prospective assessment of the predictive value of alpha-glutathione S-transferase for intestinal ischemia.

Numai utilizatorii înregistrați pot traduce articole

Nonspecific investigations resulting in treatment delays contribute to the 30 per cent mortality associated with acute mesenteric ischemia (AMI). As preliminary studies indicate that alpha-glutathione S-transferase (alpha-GST) is elevated in AMI we compare the ability of alpha-GST against

Thoracic epidural bupivacaine attenuates inflammatory response, intestinal lipid peroxidation, oxidative injury, and mucosal apoptosis induced by mesenteric ischemia/reperfusion.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND We conducted this study to evaluate the effects of thoracic epidural anesthesia (TEA) on inflammatory response, lipid peroxidation, and oxidative stress in a rat model of mesenteric ischemia/reperfusion (I/R). METHODS Rats were divided into 4 groups: sham group (n=6; sham laparotomy),

Serum markers for early detection of patients with mesenteric ischemia after cardiac surgery.

Numai utilizatorii înregistrați pot traduce articole

Mesenteric ischemia (MESI) is a rare but often fatal complication in patients after cardiac surgery. Non-specific clinical symptoms and lack of specific laboratory parameters complicate the diagnosis. We evaluated potential serum markers for MESI in cardiac surgery

Poly (ADP-ribose) synthetase mediates intestinal mucosal barrier dysfunction after mesenteric ischemia.

Numai utilizatorii înregistrați pot traduce articole

Peroxynitrite-mediated DNA strand breaks trigger poly (ADP-ribose) synthetase (PARS) activation, resulting in intracellular energetic failure and organ dysfunction. We investigated the role of PARS activation on the inflammatory and functional response of the intestine to mesenteric

Serological biomarkers for acute mesenteric ischemia.

Numai utilizatorii înregistrați pot traduce articole

Acute mesenteric ischemia (AMI) defines a complex of conditions characterized by an interruption of the splanchnic circulation, leading to insufficient oxygen delivery or utilization to fill the metabolic needs of the visceral organs. Early diagnosis and immediate therapy are the cornerstones of

Challenges in diagnosing mesenteric ischemia.

Numai utilizatorii înregistrați pot traduce articole

Early identification of acute mesenteric ischemia (AMI) is challenging. The wide variability in clinical presentation challenges providers to make an early accurate diagnosis. Despite major diagnostic and treatment advances over the past decades, mortality remains high. Arterial embolus and superior

Current status on plasma biomarkers for acute mesenteric ischemia.

Numai utilizatorii înregistrați pot traduce articole

Clinical diagnosis of acute mesenteric ischemia is difficult. The aim of this review is to provide current status on the search for an accurate plasma biomarker for acute mesenteric ischemia. A search using the medical subject heading terms marker and mesenteric ischemia or intestinal ischemia or

Biomarkers for acute mesenteric ischemia diagnosis: state of the art and perspectives.

Numai utilizatorii înregistrați pot traduce articole

Acute mesenteric ischemia (AMI) is one of the most severe diagnostic and therapeutic vital emergencies. This affection is characterized by the insufficient blood supply to the gastrointestinal tract, related to an occlusive or non-occlusive mechanism, resulting in an ischemic and inflammatory injury

Diagnostic accuracy of novel serological biomarkers to detect acute mesenteric ischemia: a systematic review and meta-analysis.

Numai utilizatorii înregistrați pot traduce articole

Laparotomy remains the gold standard for diagnosis of acute mesenteric ischemia (AMI), but is often unhelpful or too late due to non-specific clinical and radiological signs. This systematic review and meta-analysis aims to evaluate the diagnostic accuracy of the novel serological biomarkers

Curcumin nutrition for the prevention of mesenteric ischemia-reperfusion injury: an experimental rodent model.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Curcumin is an anti-oxidant molecule known to be a potent inhibitor of nuclear factor-kappaB (NF-kappaB). It has been shown to attenuate ischemia/reperfusion (I/R) injury in several organ systems. In this study, we sought to investigate the effects of curcumin on the prevention of

Melatonin and 1400 W ameliorate both intestinal and remote organ injury following mesenteric ischemia/reperfusion.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Acute intestinal ischemia reperfusion (I/R) injury affects not only the intestines but also remote organs due to pro-inflammatory and tissue injurious factors. Thus, we aimed to investigate the roles of melatonin (a powerful antioxidant) and 1400W (a strong inhibitor of inducible nitric

The effects of apelin on mesenteric ischemia and reperfusion damage in an experimental rat model.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Intestinal ischemia-reperfusion (I/R) injury is associated with high morbidity and mortality rates. There is ongoing research to find an effective preventive or treatment agent. We aimed to evaluate the effects of apelin 13 (AP) on intestinal I/R injury in a rat model. METHODS Twenty-four

Pyrrolidine dithiocarbamate prevents 60 minutes of warm mesenteric ischemia/reperfusion injury in rats.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Pyrrolidine dithiocarbamate (PDTC) is a low-molecular-weight thiol antioxidant and potent inhibitor of nuclear factor-kappaB (NF-kappaB) activation. It has been shown to attenuate harmful effects of ischemia/reperfusion (I/R) injury in many organs. In recent animal studies, destructive

TLR ligand decreases mesenteric ischemia and reperfusion injury-induced gut damage through TNF-alpha signaling.

Numai utilizatorii înregistrați pot traduce articole

Ischemic gut contributes to the development of sepsis and organ failure in critically ill patients. Toll-like receptors (TLRs) have been reported to mediate the pathophysiology of organ damage following ischemia/reperfusion (I/R) injury. We hypothesize that LPS, a ligand for TLR4, decreases

Proanthocyanidin protects intestine and remote organs against mesenteric ischemia/reperfusion injury.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Intestinal ischemia/reperfusion (IR) induces a systemic inflammatory response and releases harmful substances that may affect the function and integrity of distant organs such as lung, liver, and kidney. We conducted this study to find out if proanthocyanidins (PA) has protective effects
