ISG15/USP18/STAT2 is a molecular hub regulating IFN I-mediated control of Dengue and Zika virus replication.

The establishment of a virus infection is the result of the pathogen's ability to replicate in a hostile environment generated by the host's immune system. Here, we found that ISG15 restricts Dengue and Zika viruses' replication through the stabilization of its binding partner USP18. ISG15 expression was necessary to control DV replication driven by both autocrine and paracrine type one interferon (IFN-I) signaling.

Cannabinoid CB receptor agonist reduces local and systemic inflammation associated with pneumonia-induced sepsis in mice.

Sepsis is a severe condition secondary to dysregulated host response to infection leading to tissue damage and organ dysfunction. Cannabinoid CB receptor has modulatory effects on the immune response. Therefore, this study investigated the effects of a cannabinoid CB receptor agonist on the local and systemic inflammatory process associated with pneumonia-induced sepsis.

DNA-PKcs restricts spreading and is required for effective antiviral response.

(ZIKV) is a single-strand RNA mosquito-borne flavivirus with significant public health impact. ZIKV infection induces double-strand DNA breaks (DSBs) in human neural progenitor cells that may contribute to severe neuronal manifestations in newborns. The DNA-PK complex plays a critical role in repairing DSBs and in the innate immune response to infection.

Perioperative antimicrobial prophylaxis in patients undergoing pancreatoduodenectomy: retrospective analysis of bacteriological profile and susceptibility.

Background: Pancreatic tumours are frequently associated with obstructive jaundice requiring preoperative biliary drainage (PBD) before pancreatoduodenectomy (PD), exposing patients to infectious complications. This study aims to compare postoperative complications after PD with or without PBD and to analyse bile bacteriology and antibiotic susceptibility.

Methods: All patients undergoing PD between 2014 and 2019 were retrospectively evaluated, and postoperative outcomes were compared according to PBD use.

Oleate Hydratase in Lactobacillus delbrueckii subsp. LBP UFSC 2230 Catalyzes the Reversible Conversion between Linoleic Acid and Ricinoleic Acid.

Conjugated linoleic acid (CLA) has been the subject of numerous studies in recent decades because of its associated health benefits. CLA is an intermediate product of the biohydrogenation pathway of linoleic acid (LA) in bacteria. Several bacterial species capable of efficiently converting LA into CLA have been widely reported in the literature, among them Lactobacillus delbrueckii subsp.

Effect of dexmedetomidine on Nociception Level Index-guided remifentanil antinociception: A randomised controlled trial.

Background: The effect of dexmedetomidine on Nociception Level Index-guided (Medasense, Israel) antinociception to reduce intra-operative opioid requirements has not been previously investigated.

Objective: We aimed to determine if low-dose dexmedetomidine would reduce remifentanil requirements during Nociception Level Index-guided antinociception without increasing complications associated with dexmedetomidine.

Design: Double-blind randomised controlled trial.

Extracorporeal membrane oxygenation for refractory cardiac arrest: a retrospective multicenter study.

Purpose: The aim of this study was to assess the neurologic outcome following extracorporeal cardiopulmonary resuscitation (ECPR) in five European centers.

Methods: Retrospective database analysis of prospective observational cohorts of patients undergoing ECPR (January 2012-December 2016) was performed. The primary outcome was 3-month favorable neurologic outcome (FO), defined as the cerebral performance categories of 1-2.

An evolutionary recent IFN/IL-6/CEBP axis is linked to monocyte expansion and tuberculosis severity in humans.

Monocyte counts are increased during human tuberculosis (TB) but it has not been determined whether () directly regulates myeloid commitment. We demonstrated that exposure to directs primary human CD34 cells to differentiate into monocytes/macrophages. In vitro myeloid conversion did not require type I or type II IFN signaling.

Comparison of extracorporeal and conventional cardiopulmonary resuscitation: a retrospective propensity score matched study.

Background: The potential benefit of extracorporeal cardiopulmonary resuscitation (ECPR) compared to conventional CPR (CCPR) for patients with refractory cardiac arrest (CA) remains unclear.

Methods: This study is a retrospective analysis of a prospective database of CA patients, which includes all consecutive adult patients admitted to the Department of Intensive Care after CA between January 2012 and December 2017. The decision to initiate ECPR was made by the attending physician and ECPR performed by the ECPR team, which is composed of ICU physicians.

Genome-wide analyses reveal a highly conserved Dengue virus envelope peptide which is critical for virus viability and antigenic in humans.

Targeting regions of proteins that show a high degree of structural conservation has been proposed as a method of developing immunotherapies and vaccines that may bypass the wide genetic variability of RNA viruses. Despite several attempts, a vaccine that protects evenly against the four circulating Dengue virus (DV) serotypes remains elusive. To find critical conserved amino acids in dengue viruses, 120 complete genomes of each serotype were selected at random and used to calculate conservation scores for nucleotide and amino acid sequences.

Hepatic DNA deposition drives drug-induced liver injury and inflammation in mice.

Unlabelled: Drug-induced liver injury (DILI) is an important cause of acute liver failure, with limited therapeutic options. During DILI, oncotic necrosis with concomitant release and recognition of intracellular content amplifies liver inflammation and injury. Among these molecules, self-DNA has been widely shown to trigger inflammatory and autoimmune diseases; however, whether DNA released from damaged hepatocytes accumulates into necrotic liver and the impact of its recognition by the immune system remains elusive.
