Mitochondrial Dysfunction in Lung Resident Mesenchymal Stem Cells from Idiopathic Pulmonary Fibrosis Patients

Idiopathic pulmonary fibrosis (IPF) is characterized by an aberrant repair response with uncontrolled turnover of extracellular matrix involving mesenchymal cell phenotypes, where lung resident mesenchymal stem cells (LRMSC) have been supposed to have an important role. However, the contribution of LRMSC in lung fibrosis is not fully understood, and the role of LRMSC in IPF remains to be elucidate

Seasonal variations in acidogenic fermentation of filter primary sludge

Primary treatment of municipal wastewater by rotating belt filtration followed by hydrolysis and acidogenic fermentation of the filter primary sludge (FPS) at ambient temperature was studied at pilot-scale during one year. The seasonal variations of volatile fatty acids (VFAs), nutrient release and soluble COD production as well as microbial community assembly were assessed, leading to novel findi

Investigation of HIF-2α interaction partners and transcriptional activity under hypoxic conditions in diffuse intrinsic pontine glioma cells

Samverkande proteiner vid syrebrist under inflytande av inhibitorn PT2385 i hjärntumörceller från barn DIPG är en typ av hjärncancer hos barn som är placerad i övre delen av nacken vilket gör den svår att operera. Ledsamt nog finns ingen behandling för denna sjukdom, och patienter behandlas ofta med strålning för att förlänga livet med några enstaka månader. Hos den typiska patienten så överlevePurpose: The HIF-2α inhibitor PT2385 inhibits complex formation between HIF-2a and ARNT1 and thereby blocks HIF-2a transcriptional activation. It has been proven to extend survival in renal cancer, while its effects in pediatric brain cancer are unknown. This study is to investigate the effect of PT2385 in diffuse intrinsic pontine glioma (DIPG) cells, as well as to investigate HIF-2a interaction

Skin permeation studies of chromium species – Evaluation of a reconstructed human epidermis model

A reconstructed human epidermis (RHE) model, the EpiDerm, was investigated and compared to human skin ex vivo regarding tissue penetration and distribution of two chromium species, relevant in both occupational and general exposure in the population. Imaging mass spectrometry was used in analysis of the sectioned tissue. The RHE model gave similar results compared to human skin ex vivo for skin pe

Maternal separation differentially modulates early pathology by sex in 5xFAD Alzheimer's disease-transgenic mice

Alzheimer's disease (AD) is the most common neurodegenerative disease. Most cases of AD are considered idiopathic and likely due to a combination of genetic, environmental, and lifestyle-related risk factors. Despite occurring decades before the typical age of an AD diagnosis, early-life stress (ELS) has been suggested to have long-lasting effects that may contribute to AD risk and pathogenesis. S

Drying intensity and acidity slow down microbial growth recovery after rewetting dry soils

Soil microbes perceive drying and rewetting (DRW) events as more or less harsh depending on the previous soil moisture history. If a DRW event is not perceived as harsh, microbial growth recovers rapidly after rewetting (referred to as ‘type 1’ response), while a harsh DRW will be followed by a delayed growth recovery (‘type 2’ response). Predicting these responses based on pedoclimatic factors is

Ex‐situ synchrotron X‐ray diffraction study of CO2 corrosion‐induced surface scales developed in low‐alloy steel with different initial microstructure

The CO2 corrosion-induced scale developed in the surface region of the low-grade carbon steel is thoroughly investigated to understand the corrosion mechanisms involved during exposure to CO2-saturated aqueous environments. In this work, in addition to the electron microscopy and lab-source X-ray diffraction (XRD) methods, ex-situ depth-resolved phase identification of the corrosion scales develop

Thermal boundary condition studies in large aspect ratio Rayleigh–Bénard convection

We study the influence of thermal boundary conditions on large aspect ratio Rayleigh–Bénard convection by a joint analysis of experimental and numerical data sets for a Prandtl number Pr=7 and Rayleigh numbers Ra=105−106. The spatio-temporal experimental data are obtained by combined Particle Image Velocimetry and Particle Image Thermometry measurements in a cuboid cell filled with water at an asp

Making policy-relevant knowledge in the IPCC Special Report on 1.5 degrees : An analysis of reviewer comments

The Intergovernmental Panel on Climate Change (IPCC) maintains a fine balance between scientific credibility and policy-relevance. The IPCC's review process plays an important role in ensuring that this takes place. This paper looks at the review process of the Summary for Policymakers of the Special Report on Global Warming of 1.5 Degrees (SR15) published in 2018. We apply a framework for the mak

Circulating tumour HPV16 DNA quantification – A prognostic tool for progression-free survival in patients with HPV-related oropharyngeal carcinoma receiving curative chemoradiotherapy

Background and Purpose: Circulating tumour (ct) human papillomavirus (HPV) DNA is detectable in HPV-related oropharyngeal carcinoma (OPSCC) patients and has the potential to become an important clinical tool. This study aimed to evaluate the prognostic significance of ctHPV16-DNA kinetics during treatment with chemoradiotherapy in HPV-related OPSCC. Patients with p16-positive OPSCC recruited to th

Interface engineering of cellobiose dehydrogenase improves interdomain electron transfer

Cellobiose dehydrogenase (CDH) is a bioelectrocatalyst that enables direct electron transfer (DET) in biosensors and biofuel cells. The application of this bidomain hemoflavoenzyme for physiological glucose measurements is limited by its acidic pH optimum and slow interdomain electron transfer (IET) at pH 7.5. The reason for this rate-limiting electron transfer step is electrostatic repulsion at t

Tuneable 2D surface Bismuth incorporation on InAs nanosheets

The chemical bonding at the interface between compound semiconductors and metals is central in determining electronic and optical properties. In this study, new opportunities for controlling this are presented for nanostructures. We investigate Bi adsorption on 2D wurtzite InAs (112̄0) nanosheets and find that temperature-controlled Bi incorporation in either anionic- or cationic-like bonding is p

In-situ electrochemical synthesis of heteroatoms-doped reduced graphene oxide toward nonradical degradation of tetracycline

Nonradical-based advanced oxidation processes (AOPs) catalyzed by defective carbonaceous materials have exhibited great superiorities in trace antibiotics removal from natural water matrices. However, the complicated, extensive and highly-energy consumed synthesis methods are seriously hindering its development and application. Herein an in-situ electrochemical synthesis technology was developed a
