Photorhabdus asymbiotica is one of the three recognized species of the Photorhabdus genus, which consists of gram-negative bioluminescent bacteria belonging to the family Morganellaceae. These bacteria live in a symbiotic relationship with nematodes from the genus Heterorhabditis, together forming a complex that is highly pathogenic for insects. Unlike other Photorhabdus species, which are strictly entomopathogenic, P. asymbiotica is unique in its ability to act as an emerging human pathogen. Analysis of the P...

Sarcoidosis is a systemic granulomatous disease of unknown etiology. Recent studies demonstrated that its pathogenesis is related with enhanced oxidative stress (protein carbonylation and lipid peroxidation) and alterations in the circulating lipid profile. Alterations of lipid metabolism (including the reduction in high-density lipoprotein cholesterol levels and apolipoprotein A1 concentrations) induce plasma membrane, bronchial and lung capillary endothelial cell damage in sarcoidosis patients. Dyslipidemia is associated with increased oxidative stress, diminished overall antioxidative protection and increased risk for atherosclerosis...

BACKGROUND: Puumala hantavirus (PUUV) causes haemorrhagic fever with renal syndrome characterized by thrombocytopenia, capillary leakage and acute kidney injury (AKI) with proteinuria and haematuria. Although the typical histologic lesion is acute tubulointerstitial nephritis, the amount of glomerular proteinuria predicts the severity of upcoming AKI. Here, we studied the associations of haematuria and proteinuria with the severity of emerging AKI, thrombocytopenia and markers of coagulation and fibrinolysis in PUUV infection...

The use of peripherally inserted central catheters (PICCs) is increasing rapidly worldwide. A number of patient-related, clinical-related and device-related characteristics might be risk factors for PICC-related thrombosis. We retrospectively reviewed a database of 320 consecutive patients who underwent PICC insertion between December 2014 and December 2015 at the First Affiliated Hospital of Xi'an Jiaotong University to explore the potential associations between risk factors and PICC-associated thrombosis...

OBJECTIVE: Anxiety and depression are associated with an activation of coagulation and an impairment of fibrinolysis, which may contribute to the increased cardiovascular risk associated with the two disorders. However, very few studies have examined the impact of psychological distress on coagulation factors in coronary artery disease patients. The aim of this study was to assess the correlation between anxiety/depression and factors of coagulation and fibrinolysis in patients who had suffered an acute MI three months prior...

BACKGROUND: Platelets have been involved in both immune surveillance and host defense against severe infection. To date, whether platelet phenotype or other hemostasis components could be associated with predisposition to sepsis in critical illness remains unknown. The aim of this work was to identify platelet markers that could predict sepsis occurrence in critically ill injured patients. METHODS: This single-center, prospective, observational, 7-month study was based on a cohort of 99 non-infected adult patients admitted to ICUs for elective cardiac surgery, trauma, acute brain injury, and post-operative prolonged ventilation and followed up during ICU stay...

INTRODUCTION: Out-of-hospital cardiac arrest (OHCA) has an annual incidence of approximately 60 000 in the UK. Less than 10% of those who receive resuscitation survive to hospital discharge. For OHCA of a presumed cardiac cause, the optimal antiplatelet therapy is currently unknown. Previous studies indicate that a procoagulopathic state exists postcardiac arrest which may contribute to the formation of thrombi and contribute to poor outcomes. However, the administration of antiplatelet therapies needs to be balanced against the increased risk of bleeding that these individuals face...

OBJECTIVES: Obesity prevalence among people living with HIV (HIV+) is rising. HIV and obesity are proinflammatory states, but their combined effect on inflammation (measured by interleukin 6, IL-6), altered coagulation (D-dimer), and monocyte activation (soluble CD14, sCD14) is unknown. We hypothesized inflammation increases when obesity and HIV infection co-occur. METHODS: The Veterans Aging Cohort Study survey cohort is a prospective, observational study of predominantly male HIV+ veterans and veterans uninfected with HIV; a subset provided blood samples...

Pathologic alterations in haemostasis cause bleeding disorders, but it is unknown if variation within the normal range relates to intracerebral haemorrhage (ICH) risk. It was our objective to assess the prospective associations of haemostasis biomarkers with ICH risk. The REasons for Geographic and Racial Differences in Stroke study (REGARDS) recruited 30,239 U. S. individuals aged ≥45 years. ICH was ascertained through biannual telephone contact and review of deaths followed by medical record evaluation...

Vancomycin is known to bind to Zn(II) and can induce a zinc starvation response in bacteria. Here we identify a novel polymerization of vancomycin dimers by structural analysis of vancomycin-Zn(II) crystals and fibre X-ray diffraction. Bioassays indicate that this structure is associated with an increased antibiotic activity against bacterial strains possessing high level vancomycin resistance mediated by the reprogramming of peptidoglycan biosynthesis to use precursors terminating in D-Ala-D-Lac in place of D-Ala-D-Ala...

Stacking interactions involving substituted contorted hexabenzocoronene (c-HBC) with C60 were studied at the B97-D3M(BJ)/TZVPP//B97-D/TZV(2d,2p) level of theory. First, we showed that substituent effects in benzeneC60 complexes are uncorrelated with those in the benzene sandwich dimer, underscoring the importance of local, direct interactions in substituent effects in stacking interactions. Second, we showed that c-HBC preferentially forms stacked homodimers over complexes with C60; however, if the bowl depth of c-HBC is increased beyond 1...

BACKGROUND AND PURPOSE: Transient cerebral hypoxia may induce neuronal injury through an ischemia-reperfusion (I/R) response, with a subsequent activation of inflammation and coagulation-fibrinolysis. During carotid endarterectomy (CEA), the artery is clamped, which might impair the regional cerebral perfusion and initiate a local I/R response. Data suggest that the CD40-CD40 ligand dyad acts as a modulator in the induced activation. The aim of this study was to locally measure soluble CD40 ligand (sCD40L), in conjunction with inflammation and coagulation activation markers, during CEA...
