A Systematic Characterization of Aquaporin-9 Expression in Human Normal and Pathological Tissues

AQP9 is known to facilitate hepatocyte glycerol uptake. Murine AQP9 protein expression has been verified in liver, skin, epididymis, epidermis and neuronal cells using knockout mice. Further expression sites have been reported in humans. We aimed to verify AQP9 expression in a large set of human normal organs, different cancer types, rheumatoid arthritis synovial biopsies as well as in cell lines

Concomitant contact allergies to formaldehyde, methylchloroisothiazolinone/methylisothiazolinone, methylisothiazolinone, and fragrance mixes I and II

Background: Contact allergies to the preservatives formaldehyde and methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI) have been reported to appear together at a statistically significant level. Recently, revisions concerning the patch test preparations of MCI/MI, MI and formaldehyde have been recommended for the European baseline series. Aim: To investigate (i) the number of concomitant

NEM and filipin increase albumin transport in lung microvessels

This study was undertaken to evaluate the role of transcytosis as a bulk transfer mechanism for the passage of albumin from blood to tissue. Isolated rat lungs were continuously weighed and perfused with an albumin-serum buffer solution under strictly controlled hemodynamic conditions, which allowed measurements of microvascular pressure and of the capillary filtration coefficient (LpS). With the

Biological Activities of Natural and Semi-Synthetic Pseudo-Guaianolides: Inhibition of Transcription Factors

Popular Abstract in English The sesquiterpene lactones is an important group of natural products, and they are present in many medicinal plants. Their most important biological activities are anti-inflammatory and anti-cancer activity, although for many decades their potential use as drugs was dismissed. The main reason for this was their alkylating capacity, reacting with thiol functions in proteDamsin (1) is a natural sesquiterpene lactone (SL) isolated from Ambrosia arborescens Mill., a plant used in the Andes as antiinflammatory medicine. This natural product is an inhibitor of NF- κB, a protein complex that controls the transcription of many genes in mammalian cells, and has a potential for standing model for the development of new anti-cancer lead structures. In order to improve the

Polymer-Graft-Mediated Interactions between Colloidal Spheres

Aqueous dispersions of fluorinated colloidal spheres bearing grafted poly(ethylene glycol) (PEG) are studied as a function of salt and particle concentration with the aim of improving the understanding of interactions among polymer-grafted particles. These dispersions can sustain large concentrations of salt, but crystals nucleate in dilute dispersions when a sufficient Na2CO3 concentration is rea

BIM Inertia: Contracts & Behaviours

Whilst Building Information Modelling (BIM) promises significant improvements in construction quality and efficiency, current contractual models do not encourage its use; indeed actively inhibit the collaboration at its core. To help bring BIM into the mainstream, it is claimed we need to re-craft existing contractual relationships to facilitate collaborative decision making and to equitably alloc

Numerical Investigation of Methane/Hydrogen/Air Partially Premixed Flames in the SGT-800 Burner Fitted to a Combustion Rig

The Siemens SGT-800 3rd generation DLE burner fitted to an atmospheric combustion rig has been numerically investigated. Pure methane and methane enriched by 80 vol% hydrogen flames have been considered. A URANS (Unsteady Reynolds Averaged Navier-Stokes) approach was used in this study along with the k − ω SST and the k − ω SST-SAS models for the turbulence transport. The chemistry is coupled to t

Evaluation of sub grid scale and local wall models in Large-eddy simulations of separated flow

The performance of the Sub Grid Scale models is studied by simulating a separated flow over a wavy channel. The first and second order statistical moments of the resolved velocities obtained by using Large-Eddy simulations at different mesh resolutions are compared with Direct Numerical Simulations data. The effectiveness of modeling the wall stresses by using local log-law is then tested on a rel
