It is important to analyze the influence of these products as they pertain to medical and surgical postoperative complications.

A high-throughput liquid chromatography-tandem mass spectrometry assay for the simultaneous quantification of -cresol sulfate, -cresol glucuronide, indoxyl sulfate, and indoxyl glucuronide in HepaRG culture medium and the demonstration of mefenamic acid as a potent and selective detoxifying agent.

Background: -cresol and indole are uremic compounds which undergo sulfonation to generate the highly toxic -cresol sulfate (CS) and indoxyl sulfate (IxS). They are also subjected to glucuronidation to produce the less toxic -cresol glucuronide (CG) and indoxyl glucuronide (IG). We developed and validated an assay to quantify these metabolites in HepaRG cells.

Heterogeneous cardiac sympathetic innervation gradients promote arrhythmogenesis in murine dilated cardiomyopathy.

Ventricular arrhythmias (VAs) in heart failure are enhanced by sympathoexcitation. However, radiotracer studies of catecholamine uptake in failing human hearts demonstrate a proclivity for VAs in patients with reduced cardiac sympathetic innervation. We hypothesized that this counterintuitive finding is explained by heterogeneous loss of sympathetic nerves in the failing heart.

Vagal Nerve Stimulation Reduces Ventricular Arrhythmias and Mitigates Adverse Neural Cardiac Remodeling Post-Myocardial Infarction.

This study sought to evaluate the impact of chronic vagal nerve stimulation (cVNS) on cardiac and extracardiac neural structure/function after myocardial infarction (MI). Groups were control, MI, and MI + cVNS; cVNS was started 2 days post-MI. Terminal experiments were performed 6 weeks post-MI.

Tiered sympathetic control of cardiac function revealed by viral tracing and single cell transcriptome profiling.

The cell bodies of postganglionic sympathetic neurons innervating the heart primarily reside in the stellate ganglion (SG), alongside neurons innervating other organs and tissues. Whether cardiac-innervating stellate ganglionic neurons (SGNs) exhibit diversity and distinction from those innervating other tissues is not known. To identify and resolve the transcriptomic profiles of SGNs innervating the heart, we leveraged retrograde tracing techniques using adeno-associated virus (AAV) expressing fluorescent proteins (GFP or Td-tomato) with single cell RNA sequencing.

Essential phospholipids for nonalcoholic fatty liver disease associated with metabolic syndrome: A systematic review and network meta-analysis.

Background: Essential phospholipids (EPL) are used for the supportive treatment of non-alcoholic fatty liver disease (NAFLD), but data are mostly from small-scale studies.

Aim: To evaluate the efficacy of EPL treatment in adult patients with NAFLD and type 2 diabetes and/or obesity.

Methods: The MEDLINE, PubMed, Embase, and Cochrane databases were searched up to March 2019 for clinical trials and comparative observational studies.

The search of potential inhibitors of the AcrAB-TolC system of multidrug-resistant Escherichia coli: an in silico approach.

The number of infections caused by multidrug antibiotic resistance (MDR) species is increasing globally. The efflux pump system, AcrAB-TolC, confers Escherichia coli resistance to many antibiotics and results in poor treatment outcomes. Different rational drug design techniques were employed to search for a safe and effective AcrAB-TolC system inhibitor.

Docetaxel-Induced Stevens-Johnson Syndrome in a Patient with Metastatic Prostate Adenocarcinoma.

Docetaxel is a commonly used chemotherapeutic agent in a variety of cancer treatment regimens. We present a case of apparent docetaxel-induced Stevens-Johnson syndrome (SJS) in a patient recently treated for metastatic prostate cancer. This medication is not classically associated with the development of SJS but in our case, along with a number of other case reports, and a single phase II clinical trial, an association was recognized.

Investigational drugs for the treatment of acute myocardial infarction: focus on antiplatelet and anticoagulant agents.

Background: Advances in our understanding of the complex pathophysiologic mechanisms responsible for high-risk atherosclerotic plaque rupture resulting in acute myocardial infarction (AMI) have led to the development of numerous antiplatelet and anticoagulant agents for treatment of AMI.

Areas Covered: We review various antithrombotic drugs which were recently investigated for the treatment of AMI. A MEDLINE search for relevant articles on newer antiplatelet agents and anticoagulants drugs for the treatment of AMI was performed, and important original investigations were reviewed.

Genome-wide association study identifies novel type II diabetes risk loci in Jordan subpopulations.

The prevalence of Type II Diabetes (T2D) has been increasing and has become a disease of significant public health burden in Jordan. None of the previous genome-wide association studies (GWAS) have specifically investigated the Middle East populations. The Circassian and Chechen communities in Jordan represent unique populations that are genetically distinct from the Arab population and other populations in the Caucasus.

Standard triple therapy versus sequential therapy for eradication of Helicobacter pylori in treatment naïve and retreat patients.

Background And Study Aims: Untreated Helicobacter pylori infection causes increased risk of gastric cancer, GI morbidity and mortality. Standard treatment for eradication of Helicobacter pylori infection, is the triple therapy which consists of a proton pump inhibitor; together with two antibiotics (amoxicillin 1000mg with clarithromycin 500mg or metronidazole 400mg) given twice daily for 7-14days. Recent evidence revealed, that cure rates of Helicobacter pylori infection with triple therapy had fallen below satisfactory targets.
