Management of complications post-liver transplantation (LT) includes immunosuppressive manipulations with the aim to reduce the overall burden of immunologic suppression and compensate for renal, cardiovascular, metabolic toxicities, and for the increased oncologic risk. Two approaches can be implemented to reduce immunosuppression-related adverse events: upfront schedules tailored to the pretransplant individual patient's risk profile versus downstream modifications in the event of immunosuppression-related complications...

Novel treatment strategies for tuberculosis are urgently needed. Many different preclinical models assessing anti-tuberculosis drug activity are available, but it is yet unclear which combination of models is most predictive of clinical treatment efficacy. The aim of this study was to determine the role of our in vitro time kill-kinetics assay as an asset to a predictive preclinical modeling framework assessing anti-tuberculosis drug activity. The concentration- and time-dependent mycobacterial killing capacities of six anti-tuberculosis drugs were determined during exposure as single drugs or in dual, triple and quadruple combinations towards a Mycobacterium tuberculosis Beijing genotype strain and drug resistance was assessed...

The mouse olfactory system is often used to study mechanisms of neural circuit formation because of its simple anatomical structure. An Olfactory Sensory Neuron (OSN) is a bipolar cell with a single dendrite and a single unbranched axon. An OSN expresses only one Olfactory Receptor (OR) gene, OSNs expressing a given type of OR converge their axons to a few sets of invariant glomeruli in the Olfactory Bulb (OB). A remarkable feature of OSN projection is that the expressed ORs play instructive roles in axonal projection...

BACKGROUND AND STUDY AIMS: The success rate of Helicobacter pylori (H. pylori) eradication with the classical triple therapy is gradually declining. In this study, we aimed to compare and assess the efficacies of six different eradication regimens including sequential protocols. PATIENTS AND METHODS: Endoscopically confirmed nonulcer dyspepsia patients were enrolled. H. pylori presence was determined either histologically or by a rapid urease test. Treatment-naive patients were randomly assigned to an either one of three 10-day (OAC, OTMB, and OACB) or one of three sequential protocols (OA+OCM, OA+OCMB, and OA+OMDB) (O=omeprazole, A=amoxicillin, C=clarithromycin, T=tetracycline, M=metronidazole, B=bismuth, D=doxycycline)...

BACKGROUND: In several developed countries, as obesity prevalence doubles it has quadrupled for morbid obesity (BMI ≥ 40 kgm(-2)). As more individuals with morbid obesity present for weight loss treatment there is a greater need to understand their dietary habits. No reviews were found in the literature, therefore this systematic review aims to identify and describe the existing evidence on the usual dietary intake of individuals with morbid obesity including those from a general population and those seeking treatment such as weight loss surgery...

The main problem of Helicobacter pylori (H. pylori) infection management is linked to antibiotic resistances. This phenomenon has grown in the last decade, inducing a dramatic decline in conventional regimen effectiveness. The causes of resistance are point mutations in bacterial DNA, which interfere with antibiotic mechanism of action, especially clarithromycin and levofloxacin. Therefore, international guidelines have recently discouraged their use in areas with a relevant resistance percentage, suggesting first-line schedules with expected high eradication rates, i...

In vitro models of the human blood-brain barrier (BBB) are highly desirable for drug development. This study aims to analyze a set of ten different BBB culture models based on primary cells, human induced pluripotent stem cells (hiPSCs), and multipotent fetal neural stem cells (fNSCs). We systematically investigated the impact of astrocytes, pericytes, and NSCs on hiPSC-derived BBB endothelial cell function and gene expression. The quadruple culture models, based on these four cell types, achieved BBB characteristics including transendothelial electrical resistance (TEER) up to 2,500 Ω cm(2) and distinct upregulation of typical BBB genes...

In Vietnam, a country with high tuberculosis (137/100.000 population) and multidrug-resistant (MDR)-TB burdens (7.8/100.000 population), little is known about the molecular signatures of drug resistance in general and more particularly of second line drug (SLD) resistance. This study is specifically focused on Mycobacterium tuberculosis isolates resistant to four first-line drugs (FLDs) that make TB much more difficult to treat. The aim is to determine the proportion of SLD resistance in these quadruple drug resistant isolates and the genetic determinants linked to drug resistance to better understand the genetic processes leading to quadruple and extremely drug resistance (XDR)...
