The mechanism of long chain non-coding RNA (lncRNA) is diverse. LncRNA can regulate the expression of genes at multiple levels and is closely related to some pathological process, such as tumor formation, viral replication, inflammatory damage, etc. The abnormal expression of lncRNA is involved in the patho-physiological changes of the disease, and plays a key role in many links, such as the stability of mRNA, the regulation of translation level, protein transport, RNA processing and modification, and so on...

Sepsis, which is induced by severe bacterial infections, is a major cause of death worldwide, and therapies combating the disease are urgently needed. Because many drugs have failed in clinical trials despite their efficacy in mouse models, the development of reliable animal models of sepsis is in great demand. Several studies have suggested that rabbits reflect sepsis-related symptoms more accurately than mice. In this study, we evaluated a rabbit model of acute sepsis caused by the intravenous inoculation of Salmonella enterica...

Life expectancy of patients with liver cirrhosis is closely linked to the degree of liver dysfunction and the occurrence of bacterial infection. An early diagnosis of infection helps to initiate adequate and timely measures and improves outcome of cirrhotic patients. Endocan is a newly recognized biomarker of sepsis. However, there have been no studies of the trends in endocan levels in cirrhotic patients with bacterial infection and their associations with markers of infection and inflammation. This study sought to assess the diagnostic value of serum levels of endocan, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in 126 patients with cirrhosis: 51 with decompensated infected cirrhosis, 56 with decompensated uninfected and 19 with compensated uninfected cirrhosis at inclusion...

Osteopontin (OPN) is a multifunctional protein involved in various pathophysiological processes. However, the role of OPN in Pseudomonas aeruginosa-related sepsis is not yet clear. Here, we found that OPN expression was elevated in plasma and spleen samples from P. aeruginosa-infected mice. To determine the function of OPN in sepsis, we used wild-type (WT) and OPN-knockout (KO) mice with P. aeruginosa-induced bacteremia. We found that OPN-KO mice exhibited reduced mortality compared with WT mice and that OPN exacerbated spleen bleeding and functional impairment...

BACKGROUND: Sepsis remains the leading cause of death in the surgical intensive care unit. Prior studies have demonstrated a survival benefit of remote ischemic conditioning (RIC) in many disease states. The aim of this study was to determine the effects of RIC on survival in sepsis in an animal model and to assess alterations in inflammatory biochemical profiles. We hypothesized that RIC alters inflammatory biochemical profiles resulting in decreased mortality in a septic mouse model...

INTRODUCTION: Soluble CD40 ligand (sCD40L) is a protein with proinflammatory and prothrombotic effects. Previously we found higher circulating sCD40L levels in non-survivor than in survivor patients at sepsis diagnosis. Now some questions arise such as how are serum sCD40L levels during the first week of severe sepsis?, is there an association between serum sCD40L levels during the first week and mortality?, and serum sCD40L levels during the first week could be used as sepsis mortality biomarker?...

The innate immune response to lipopolysaccharide contributes substantially to the morbidity and mortality of gram-negative sepsis. Horses and humans share an exquisite sensitivity to lipopolysaccharide and thus the horse may provide valuable comparative insights into this aspect of the inflammatory response. MicroRNAs, small non-coding RNA molecules acting as post-transcriptional regulators of gene expression, have key roles in toll-like receptor signaling regulation but have not been studied in this context in horses...

In analogy to apoptosis of nucleated cells, erythrocytes may enter eryptosis characterized by cell shrinkage and cell membrane scrambling. Eryptotic erythrocytes are rapidly cleared from circulating blood and may adhere to the vascular wall. Stimulation of eryptosis thus impairs microcirculation and leads to anemia as soon as the loss of erythrocytes cannot be fully compensated by enhanced erythropoiesis. Signaling stimulating eryptosis includes increase of cytosolic Ca(2+) -activity, ceramide, caspases, calpain, p38-kinase, protein-kinase C, Janus-activated kinase 3, casein-kinase 1α, and cyclin-dependent kinase 4...
