Four new polyhydroxy pregnane glycosides, named volubilosides G−K (3, 5–7), along with three known secondary metabolites, dregeoside Da1 (1), dregeoside Ka1 (2), and volubiloside E (4) were isolated from the twigs and leaves of Dregea volubilis (DV). The chemical structures of these compounds (1–7) were elucidated using spectroscopic techniques (1D and 2D NMR and HR-ESI-MS analyses) and compared w

Many people want to play their part to tackle climate change, but often do not know where to start. Carbon Footprint (CF) Calculators pose potential for helping individuals situate themselves in climate impacting systems of which they are a part. However, little is currently known about whether and how individuals who complete CF calculators understand their CF in the context of climate change. Th

We identified a sample of 58 candidate stars with metallicity [Fe/H]-0.8 that likely belong to the old bulge spheroid stellar population, and analyse their Na and Al abundances from Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectra. In a previous work, we inspected APOGEE-Stellar Parameter and Chemical Abundance Pipeline abundances of C, N, O, Mg, Al, Ca, Si, and Ce in this s

This work examines the influence of applied external voltage in bulk electrolysis on the excited-state properties of 8′-apo-β-carotenal in acetonitrile by steady-state and ultrafast time-resolved absorption spectroscopy. The data collected under bulk electrolysis were compared with those taken without applied voltage. The steady-state measurements showed that although intensity of the S0-S2 absorp

Background: Women with adverse pregnancy outcomes may have higher subsequent risk of chronic kidney disease, but the long-term independent risks and potential causality are unclear. Objective: This study aimed to determine long-term risks of chronic kidney disease associated with 5 major adverse pregnancy outcomes in a large population-based cohort, and to assess for familial confounding using co-

In half-metallic systems, electronic conduction is mediated by a single spin species, offering enormous potential for spintronic devices. Here, using microscopic-area angle-resolved photoemission, we show that a spin-polarised two-dimensional hole gas is naturally realised in the polar magnetic semiconductor AgCrSe2 by an intrinsic self-doping at its CrSe2-terminated surface. Through comparison wi

The active manipulation of particle and cell trajectories in fluids by high-frequency standing surface acoustic waves (sSAW) allows to separate particles and cells systematically depending on their size and acoustic contrast. However, process technologies and biomedical applications usually operate with non-spherical particles, for which the prediction of acoustic forces is highly challenging and

Teamwork is considered something positive. While there is much research on teamwork in healthcare, research on teamwork in home care nursing is limited. As the need for home care nursing is likely to increase in the future, it is of great interest to investigate the circumstances associated with the implementation of teamwork in home care nursing. The present study compares the results from a larg

A positron emission tomography (PET) tracer detecting α-synuclein pathology will improve the diagnosis, and ultimately the treatment of α-synuclein-related diseases. Here we show that the PET ligand, [18F]ACI-12589, displays good in vitro affinity and specificity for pathological α-synuclein in tissues from patients with different α-synuclein-related disorders including Parkinson’s disease (PD) an

We report the application of ancestral sequence reconstruction on coronavirus spike protein, resulting in stable and highly soluble ancestral scaffold antigens (AnSAs). The AnSAs interact with plasma of patients recovered from COVID-19 but do not bind to the human angiotensin-converting enzyme 2 (ACE2) receptor. Cryo-EM analysis of the AnSAs yield high resolution structures (2.6–2.8 Å) indicating

The exponential-6 (exp-6) potential is commonly used to model fluids at high densities. In this paper, I propose a new equation of state (EOS) in the form of an analytical expression for the excess Helmholtz free energy of an exp-6 fluid. The EOS is based on extensive Monte Carlo simulations and therefore combines the excellent accuracy of the simulations with the numerical efficiency of a polynom

Manus till teaterföreställningen i ett hus vid skogens slut som gjordes på Turteatern i Stockholm."Vid civilisationens ände tittar människan yrvaket upp. En ångest som liknar en tomhet dånar i hennes inre. Strategierna för distraktion fungerar inte längre. Information flödar in i henne utan att hitta fästpunkter, politiken är lika död som de för länge sedan bortglömda gudarna, och själva pengasyst

AIMS: Heart failure (HF) patients with anaemia tend to have a worse outcome, with increased hospitalization rates, decreased exercise tolerance, and higher mortality compared to those without anaemia. Limited research exists on the association between selenium deficiency and anaemia specifically in HF patients, despite previous findings of a correlation in different populations. The BIOSTAT-CHF st

Denmark recently adopted a law to ban inappropriate treatment of any writing or object with religious significance – a peace initiative in the best interests of a multicultural society. I see this law as a step towards freedom of expression that will also help bridge social divides.

BackgroundObstructive sleep apnea (OSA) is a prevalent disorder and symptoms of nasal obstruction are highly prevalent in OSA. Treatment of nasal obstruction in OSA patients has shown modest and variable outcomes in reducing the apnea hypopnea index (AHI), but significant improvements in other indicators, such as sleep quality and daytime sleepiness as well as reductions in arousals have been obse
