REVIEW
Paula Pierozan, Regina Pessoa-Pureur
Cytoskeletal proteins are increasingly recognized as having important roles as a target of the action of different neurotoxins. In the last years, several works of our group have shown that quinolinic acid (QUIN) was able to disrupt the homeostasis of the cytoskeleton of neural cells and this was associated with cell dysfunction and neurodegeneration. QUIN is an excitotoxic metabolite of tryptophan metabolism and its accumulation is associated with several neurodegenerative diseases. In the present review, we provide a comprehensive view of the actions of QUIN upstream of glutamate receptors, eliciting kinase/phosphatase signaling cascades that disrupt the homeostasis of the phosphorylation system associated with intermediate filament proteins of astrocytes and neurons...

Healing and regeneration of bone injuries, particularly those that are associated with large bone defects, are a complicated process. There is growing interest in the application of osteoinductive and osteogenic growth factors and mesenchymal stem cells (MSCs) in order to significantly improve bone repair and regeneration. MSCs are multipotent stromal stem cells that can be harvested from many different sources and differentiated into a variety of cell types, such as preosteogenic chondroblasts and osteoblasts...

BACKGROUND: Direct carotid-cavernous sinus fistulas (CCF) are high flow arteriovenous shunts that are typically the result of a severe head injury. The endovascular treatment of these lesions includes the use of detachable balloons, coils, liquid embolic agents, and covered stents. To minimize the chance of treatment failure and subsequent complications, endoluminal reconstruction using a flow-diverting stent may be added to the treatment construct . METHODS: We present 3 cases and review the existing literature...

BACKGROUND & AIMS: Macrophage migration inhibitory factor (MIF) is a multi-potent cytokine that contributes to the inflammatory response to injury. MIF is expressed by multiple cell types; however, the cellular source and actions of MIF in alcoholic liver disease (ALD) are not well known. Here we tested the hypothesis that non-myeloid cells, specifically hepatocytes, are an important cellular source of MIF in ALD. METHODS: MIF expression was measured in HuH7 and differentiated THP-1 cells in response to ethanol...

REVIEW
David R Schreier, Christina Banks, Johannes Mathis
Road traffic injuries are projected to be the leading cause of death for those aged between 15 and 29 years by the year 2030, and sleepiness is estimated to be the underlying cause in up to 15-20% of all motor vehicle accidents. Sleepiness at the wheel is most often caused by socially induced sleep deprivation or poor sleep hygiene in otherwise healthy individuals, medical disorders, or the intake of drugs. Validated methods for objectifying sleepiness are urgently sought, particularly in the context of driving...

Hyperglycemia-induced cartilage degeneration induces osteoarthritis (OA). Since oleanolic acid (OLA) have several pharmacological effects such as anti-inflammatory, anti-oxidant, we hypothesized it possesses protection against high glucose injured cartilage. We now report that OLA decreased type X collagen and reversed the cartilage degeneration in growth plate from db/db mice. OLA increased type Ⅱ collagen expression in a concentration-dependent manner (10-50 μΜ) in high glucose-treated chondrocytes. OLA prevented the high glucose induced cell injury and decreased the level of MMP-13, PGE2 and IL-6 due to decreasing mitochondrial membrane potential and stimulated the ATP production...

BACKGROUND: Tubuloreticular inclusions (TRIs) are anastomosing networks of microtubules that are frequently found in autoimmune diseases and viral infections. In renal allografts, TRIs have been reported in glomerular endothelial cells in association with viral infections and donor specific antibodies (DSAs), but their presence in peritubular capillaries has not been explored. METHODS: We collected seven cases with TRIs out of 148 consecutive renal allograft biopsies taken from Dec...

BACKGROUND: The incidence of Blunt Carotid Artery and Vertebral Artery Injury (BCVI) is relatively low in modern trauma practice. However, these injuries may be associated with severe neurological consequences. Following the introduction of a Diagnostic Imaging Pathway in Department of Health of Western Australia, we hypothesized that this injury would be less likely to be missed, and accordingly diagnosed more frequently. METHOD: A review of all major trauma (Injury Severity Scale>15) admissions at the State Major Trauma Centre in Royal Perth Hospital was undertaken from 1995 until 2013...

The term acute tubular necrosis was thought to represent a misnomer derived from morphological studies of human necropsies and necrosis was thought to represent an unregulated passive form of cell death which was not amenable to therapeutic manipulation. Recent advances have improved our understanding of cell death in acute kidney injury. First, apoptosis results in cell loss, but does not trigger an inflammatory response. However, clumsy attempts at interfering with apoptosis (e.g. certain caspase inhibitors) may trigger necrosis and, thus, inflammation-mediated kidney injury...

Jinbeom Cho, Kiyoung Sung, Dosang Lee
BACKGROUND: Although foreign bodies (FBs) typically pass spontaneously and uneventfully through the digestive tract, a subset of such bodies may become trapped, eventually leading to significant injury. In particular, the ingestion of magnetic materials can cause serious morbidity due to proximate attraction through the intestinal wall. CASE PRESENTATION: We recently treated three pediatric patients who had ingested several magnetic foreign materials. None of these patients exhibited any clinical symptoms or signs suggestive of surgical abdomen...

BACKGROUND: Patients with acute myocardial infarction are at high risk for acute kidney injury. Novel biomarkers that can predict acute kidney injury in AMI may allow timely interventions. C-terminal fragment of agrin (CAF), a proteoglycan of the glomerular and tubular basement membrane, have been recently associated with rapid renal function deterioration and proximal tubular dysfunction. It is unknown whether elevated CAF levels may serve as a novel AKI biomarker in patients presenting with AMI...

Ischemia-reperfusion injury (IRI), induced by abnormal mitochondrial fission related apoptosis, is a major concern in liver transplantation settings. Our previous studies have demonstrated that hepatic stimulator substance (HSS) is an anti-apoptotic effector and could protect liver from IRI. However, the underlying mechanism remains unclear. In the present study, we report that in vitro and in vivo HSS could regulate mitochondrial fission and hepatocyte apoptosis during liver IRI by orchestrating the translocation and activation of dynamin-related protein 1 (Drp1)...

Severe burns induce a prolonged inflammatory response in subcutaneous adipose tissue that modulates signaling in adipose-derived stem cells (ASCs), which hold potential for healing burn wounds or generating skin substitutes. Using a 60% rat scald burn model, we conducted a series of experiments to determine which cells isolated from the adipose tissue produced inflammatory mediators and how these changes affect ASC fate and function. The stromal vascular fraction (SVF), adipocytes, and ASCs were isolated from adipose tissue at varying times up to 4 weeks postburn and from non-injured controls...
