Expression of spermine/spermidine-N1-acetyltransferase (SSAT), the rate-limiting enzyme of polyamine backconversion cascade, increases after ischemia-reperfusion injuries (IRI). We hypothesized that SSAT plays an important role in the mediation of IRI. To test our hypothesis, wild-type (SSAT-wt) and SSAT-deficient (SSAT-ko) mice were subjected to liver or kidney IRI by ligation of hepatic or re...

Document layout analysis is crucial for understanding document structures. On this task, vision and semantics of documents, relations between components contribute to the process. Though many works have been proposed exploit above information, they show unsatisfactory results. NLP-based methods model as a sequence labeling task insufficient capabilities in modeling. CV-based detection or segmen...

BACKGROUND Remote ischemic perconditioning (RIPerC), remote ischemic postconditioning (RIPostC), and remote ischemic perconditioning + postconditioning (RIPerC + RIPostC) protect against renal ischemia reperfusion injury (IRI). However, the most beneficial approach among these is not known. AIMS To compare the protective effects and study the mechanisms of three different remote ischemic cond...

Dendritic cells (DCs) are central to innate and adaptive immunity of early kidney ischemia-reperfusion injury (IRI), and strategies to alter DC function may provide new therapeutic opportunities. Sphingosine 1-phosphate (S1P) modulates immunity through binding to its receptors (S1P1-5), and protection from kidney IRI occurs in S1P3-deficient mice. Through a series of experiments we determined t...

In this study we have characterized the effects of cysteamine (CHS) on the cellular content and release of immunoreactive somatostatin (S-14 LI), insulin (IRI), and glucagon (IRG) from monolayer cultures of neonatal rat islets. Incubation of cultures with 0.1-10 mM CHS for 1 h led to an apparent, dose-dependent reduction of cellular S-14 LI that was 50% of control at 0.3 mM, 87% at 1 mM, and 95...

Objective(s): The present study was designed to evaluate of Metformin/Irinotecan-loaded poly-lactic-co-glycolic acid (PLGA) nanoparticles (NPs) effects on glutamate re-uptake time and receptor expression status in both glioblastoma multiforme (GBM) and cortex neuron cultures. The study was performed on glioblastoma cell line and primer cortex neuron.Materials and Methods: The re-uptake time and...

Ischemia-reperfusion injury (IRI) is a series of multifaceted cellular events that takes place on the resumption of oxygen delivery to the affected organ after a period of hypoxia. IRI occurs in the liver during procedures that are associated with vascular inflow obstruction followed by restoration of blood flow, particularly during orthotopic liver transplantation. IRI can result in major hepa...

Ischemia reperfusion injury (IRI) is a leading cause of acute kidney injury, a common problem worldwide associated with significant morbidity and mortality. We have recently examined the role of microRNAs (miRs) in renal IRI using expression profiling. Here we conducted mathematical analyses to determine if differential expression of miRs can be used to define a biomarker of renal IRI. Principa...

Activation of A2A adenosine receptors (A2ARs) protects kidneys from ischemia-reperfusion injury (IRI). A2ARs are expressed on bone marrow-derived (BM-derived) cells and renal smooth muscle, epithelial, and endothelial cells. To measure the contribution of A2ARs on BM-derived cells in suppressing renal IRI, we examined the effects of a selective agonist of A2ARs, ATL146e, in chimeric mice in whi...
