A new technology has recently appeared in the area of extracorporeal therapies for critically ill patients with acute kidney injury. The International Renal Research Institute of Vicenza was involved from the beginning in the development of a new continuous renal replacement therapy (CRRT) equipment with peculiar characteristics. We report the overall experience from design of the new machine to its in vitro and in vivo testing. Kibou® (Asahi Kasei Kuraray Medical Co., Ltd., Tokyo, Japan) is a new multifunctional machine designed for delivering RRT...

Acute kidney injury (AKI) is one of the most common sepsis complications, and AKI development increases the risk of sepsis episodes by affecting host immune competence. The concomitance of these 2 clinical syndromes is associated with an extremely poor prognosis with mortality rates ranging from 50 to 70%. These unacceptable outcomes reflect the poor knowledge of the underlying pathogenic mechanisms and the lack of appropriate diagnostic and therapeutic methodologies as well as of appropriate experimental models...

BACKGROUND: Pulmonary endothelial injury is a critical process in the pathogenesis of acute lung injury (ALI) during sepsis. Heat shock protein A12B (HSPA12B) is mainly expressed in endothelial cells and protects against several harmful factors. However, the effects of HSPA12B in sepsis-induced ALI and its potential mechanisms of action remain unclear. METHODS: For in vivo experiments, C57BL/6 mice were randomly divided into four groups (n=15): a sham operation group, a cecal ligation and puncture (CLP) group, a HSPA12B siRNA-CLP group and a negative control (NC) siRNA-CLP group...

Regeneration failure after primary spinal cord injury (SCI) leads to diverse clinical complications in a severity- and level of SCI-dependent manner. The cost of treating both of them (initial regeneration failure and following complications) would be prohibitive, particularly in less developed nations. The well-recognized circumstances arose from primary SCI include excitotoxicity and inflammation. SCI increases concentrations of extracellular amino acids (EAAs) in the severity-dependent manner and the maximum level of EAAs at the injury site will be reduced by distance from the injury site...

We recently generated glutathione S-transferase (GST) A3 knockout (KO) mice as a novel model to study the risk factors for liver cancer. GSTA3 KO mice are sensitive to the acute cytotoxic and genotoxic effects of aflatoxin B1 (AFB1), confirming the crucial role of GSTA3 in resistance to AFB1. We now report histopathological changes, tumor formation, biochemical changes and gender response following AFB1 treatment as well as the contribution of oxidative stress. Using a protocol of weekly 0.5 mg AFB1/kg administration, we observed extensive oval (liver stem) cell (OC) proliferation within 1-3 weeks followed by microvesicular lipidosis, megahepatocytes, nuclear inclusions, cholangiomas, and small nodules...

AIM: Acute kidney injury (AKI) is common following deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4). Early and rapid increases in serum creatinine (sCr) follow severe poisoning. We investigated the relationship of these increases with direct nephrotoxicity in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. METHODS: Multiple measures of change in kidney function were evaluated in 48 consenting patients who had serial sCr and serum cystatin C (sCysC) data available...

CONTEXT:   Comprehensive, multi-domain assessment is the standard of care after sport-related concussion. However, the relationship between performance on sideline concussion-assessment tools and in-office computerized neurocognitive testing has received little attention, and the prognostic utility of sideline measures is unknown. OBJECTIVE:   To evaluate concurrent impairment on commonly used concussion measures 24 to 48 hours postinjury while also determining the predictive utility of sideline measures on computerized neurocognitive testing in the acute to subacute recovery periods postinjury...

The present study investigated the correlation between four serum biomarkers of liver fibrosis, liver function and pathological hepatic fibrosis grade in neonatal cholestatic rats. A total of 38 Sprague‑Dawley rats, aged 3 weeks, were randomly assigned to the experimental group (EG), control group (CG) and the blank control group (BCG). EG received intragastric administration of 1% α‑naphthylisothiocyanate, 75 mg/kg, to induce acute cholestasis liver injury, CG and BCG were set as control groups. Blood samples from all groups were collected 48 h following the procedure...

BACKGROUND: During military actions, soldiers are constantly exposed to various forms of potentially harmful noises. Acute acoustic trauma (AAT) results from an impact, unexpected intense noise ≥140 dB, which generates a high-energy sound wave that can damage the auditory system. PURPOSE: We sought to characterize AAT injuries among military personnel during operation "Protective Edge," to analyze the effectiveness of hearing protection devices (HPDs), and to evaluate the benefit of steroid treatment in early-diagnosed AAT injury...

J A Sutton, R P Clauss
During 15 years, 23 clinical reports and 6 studies have demonstrated associations between sub-sedative doses of zolpidem and recoveries from brain damage due to strokes, trauma and hypoxia. Clinical findings include unexpected awakenings from vegetative states and regressions of stroke symptoms after dosing that disappear during elimination and reappear on repeat dosing. Initially single-photon emission computed tomography scans showed improved perfusion within, around and distant from infarctions. Then positron emission tomography scans and electroencephalography detected renewed metabolic and neuronal activity...

BACKGROUND: The extent of myocardial damage in patients with ST-segment elevation myocardial infarction (STEMI) depends on both the time to reperfusion as well as injury induced by ischaemia-reperfusion resulting in a cascade of cellular and humoral reactions. As a consequence of ischaemia-reperfusion in the heart, the high-temperature requirement serine peptidase 2 (HtrA2) is translocated from the mitochondria to the cytosol, whereupon it induces protease activity-dependent apoptosis mediated via caspases...

Current treatments for ischemia-reperfusion (IR)-induced acute lung injury are limited. Mesenchymal stem cell-conditioned medium (CM) has been reported to attenuate lung injury. Neural crest stem cells (NCSCs), a type of multipotent stem cells, are more easily obtained than mesenchymal stem cells. We hypothesize that NCSC-CM has anti-inflammatory properties that could protect against IR-induced lung injury in rats. In this study, NCSC-CM was derived from rat NCSCs. Typical acute lung injury was induced by 30-min ischemia followed by 90-min reperfusion in adult male Sprague-Dawley rats...

Extracellular vesicles (EVs) serve an important function as mediators of intercellular communication. Exercise is protective for the heart, although the signaling mechanisms that mediate this cardioprotection have not been fully elucidated. Here using nano-flow cytometry, we found a rapid increase in plasma EVs in human subjects undergoing exercise stress testing. We subsequently identified that serum EVs were increased by ~1.85-fold in mice after 3-week swimming. Intramyocardial injection of equivalent quantities of EVs from exercised mice and non-exercised controls provided similar protective effects against acute ischemia/reperfusion (I/R) injury in mice...

Renal dysfunction is a common complication of liver cirrhosis and of utmost clinical and prognostic relevance. Patients with cirrhosis are more prone to developing acute kidney injury (AKI) than the non-cirrhotic population. Pre-renal AKI, the hepatorenal syndrome type of AKI (HRS-AKI, formerly known as 'type 1') and acute tubular necrosis represent the most common causes of AKI in cirrhosis. Correct differentiation is imperative, as treatment differs substantially. While pre-renal AKI usually responds well to plasma volume expansion, HRS-AKI and ATN require different specific approaches and are associated with substantial mortality...

Macrophage inflammatory protein (MIP)-2 is one of the CXC chemokines and is also known as chemokine CXC ligand (CXCL2). MIP-2 affects neutrophil recruitment and activation through the p38 mitogen-activated-protein-kinase-dependent signaling pathway, by binding to its specific receptors, CXCR1 and CXCR2. MIP-2 is produced by a variety of cell types, such as macrophages, monocytes, epithelial cells, and hepatocytes, in response to infection or injury. In liver injury, activated Kupffer cells are known as the major source of MIP-2...
