Screening of stationary phase selectivities for global lipid profiling by ultrahigh performance supercritical fluid chromatography

The performance of seven sub-2-μm particle packed columns (2-picolylamine, 2-PIC; charged surface hybrid fluoro-phenyl, CSH-FP; high strength silica C18 SB, HSS-C18; diethylamine, DEA; 1-aminoanthracene, 1-AA; high density diol and ethylene bridged hybrid; BEH) was examined for lipid separation in ultra-high performance supercritical fluid chromatography (UHPSFC) coupled to quadrupole time-of-flig

Endoplasmic reticulum, Golgi, and lysosomes are disorganized in lung fibroblasts from chronic obstructive pulmonary disease patients

Chronic Obstructive Pulmonary Disease (COPD) is often caused by smoking and other stressors. This causes oxidative stress, which induces numerous changes on both the transcriptome and proteome of the cell. We aimed to examine if the endomembrane pathway, including the endoplasmic reticulum (ER), Golgi, and lysosomes, was disrupted in fibroblasts from COPD patients as opposed to healthy ever-smoker

Responses of plant cells and tissues to pulsed electric field treatments

Cell membrane electroporation/permeabilization may be achieved without affecting cell viability through strict control of the electric pulse parameters. This process is referred to as reversible permeabilization. Even if the cells survive the electric field treatment, they are subjected to stress due to the opening of pores and the struggle of the cells to recover their normal functionality. Very

Nucleation-limited composition of ternary III-V nanowires forming from quaternary gold based liquid alloys

We derive an analytic expression for the composition of a ternary solid material nucleating from a quaternary liquid melt. The calculations are based on the two-component nucleation theory with realistic descriptions of the liquid and solid phases. We apply this theory to gold-catalyzed, nucleation limited vapor-liquid-solid growth of ternary III-V nanowires. We consider ternary gallium, indium, a

The eastern boundary of Sveconorwegian reworking in the Baltic Shield,defined by 40Ar/39Ar geochronology across the southernmost Sveconorwegian Province

New 40Ar/39Ar dates of hornblende, biotite and muscovite from 13 localities along a 130 km transect in southern Sweden provide insight into the cooling and exhumation history during Sveconorwegian orogeny, from 970 to 880 Ma. The Eastern Segment represents Baltican continental crust underthrust below the western Sveconorwegian terranes at 990–970 Ma. The western part of the Eastern Segment consistNew 40Ar/39Ar dates of hornblende, biotite and muscovite from 13 localities along a 130 km transect in southern Sweden provide insight into the cooling and exhumation history during Sveconorwegian orogeny, from 970 to 880 Ma.

Viscosity reduction of pretreated softwood by endoglucanases

BACKGROUND: Cost-effective processing of lignocellulosic biomass into sugar derived products, such as biofuels or biochemicals, needs to be performed at high water insoluble solid (WIS) loading. However, the difficult rheology of such materials presents significant challenges. The aim of this study was to investigate if a Cel5A endoglucanase can be used to reduce the viscosity of two types of pret

A search for pair-produced resonances in four-jet final states at √s=13 TeV with the ATLAS detector

A search for massive coloured resonances which are pair-produced and decay into two jets is presented. The analysis uses 36.7 fb- 1 of s = 13 TeV pp collision data recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the background prediction is observed. Results are interpreted in a SUSY simplified model where the lightest supersymmetric particle is the top

Using pine bark and mussel shell amendments to reclaim microbial functions in a Cu polluted acid mine soil

An extremely acid mine soil polluted with Cu was amended with pine bark, crushed mussel shell or a 1:1 mixture of these two by-products. The performance of the soil microbial community was measured as the bacterial and fungal community growth, which were monitored during 2 years following the amendments. Pine bark caused significant increases of microbial growth rates, but with distinct difference

Social-ecological resilience and geomorphic systems

Governance of coupled social-ecological systems (SESs) and the underlying geomorphic processes that structure and alter Earth's surface is a key challenge for global sustainability amid the increasing uncertainty and change that defines the Anthropocene. Social-ecological resilience as a concept of scientific inquiry has contributed to new understandings of the dynamics of change in SESs, increasi

Inflammatory biomarker profiling in classical orthostatic hypotension : Insights from the SYSTEMA cohort

Objective: To investigate the inflammatory biomarker signature associated with classical orthostatic hypotension (OH). Methods: A cross-sectional study including 778 patients with unexplained syncope and/or orthostatic intolerance undergoing head-up tilt test (HUT) and supine blood sampling. Of these, 98 met diagnostic criteria of classical OH and 181 demonstrated normal haemodynamic response duri
