Most university biobanks begin like other university research projects, i.e. with an idea conceived by an individual researcher in pursuit of his/her own research interests, publications, funding and career. Some biobanks, however, come to have scientific value that goes beyond the projects that were initially responsible for the collection of the samples and data they contain. Such value may deri

BACKGROUND: Covid-19 transmission via exhaled aerosol particles has been considered an important route for the spread of infection, especially during super-spreading events involving loud talking or singing. However, no study has previously linked measurements of viral aerosol emissions to transmission rates.METHODS: During Feb-Mar 2021, covid-19 cases that were close to symptom onset were visited

Imaging large areas of a sample non-destructively and with high resolution is of great interest for both science and industry. For scanning coherent X-ray diffraction microscopy, i. e., ptychography, the achievable scan area at a given spatial resolution is limited by the coherent photon flux of modern X-ray sources. Multibeam X-ray ptychography can improve the scanning speed by scanning the sampl

Bacteria in the order 'Candidatus Brocadiales' within the phylum Planctomycetes (Planctomycetota) have the remarkable ability to perform anaerobic ammonium oxidation (anammox). Two families of anammox bacteria with different biogeographical distributions have been reported, marine Ca. Scalinduaceae and freshwater Ca. Brocadiaceae. Here we report evidence of three new species within a novel genus a

Människobehandlande yrken, såsom socialt arbete, syftar till att identifiera och åtgärda problem i människors liv. Hur skapas en förståelse av vad ett problem innebär? Hur nås enighet i fall där det finns flera motstridande definitioner och förklaringar till vad som ska anses vara problematisk? Detta kapitel handlar om hur en förståelse av ett problem och lösningar på det kan skapas i ett möte melMänniskobehandlande yrken, såsom socialt arbete, syftar till att identifiera och åtgärda problem i människors liv.

Terrorism comes in various forms, clear and sometimes ambiguous, by terrorist cells and sometimes by state players. Nerve agent poisoning represents one of the notorious applications of chemistry in the world. Nerve agents have historically instigated major casualties in various parts, heavily impacting lives of civilians by causing debilitating neurological and psychiatric injuries. Nerve agents

In this work we measured, by using a direct approach, the equilibrium solubility of recombinant Aβ40 peptide to be S ​= ​0.36 ​± ​0.15 ​μM in aqueous solution of 20 ​mM sodium phosphate buffer at pH 7.4. Microfluidic diffusional sizing (MDS) and mass spectrometry (MALDI-TOF/TOF) with isotope standard were used to quantify the concentration of soluble Aβ40 species coexisting with formed fibrils. A

The advent of x-ray free-electron lasers (FELs) drastically enhanced the capabilities of several analytical techniques, for which the degree of transverse (spatial) coherence of the source is essential. FELs can be operated in self-amplified spontaneous emission (SASE) or seeded configurations, which rely on a qualitatively different initialization of the amplification process leading to light emi

A piece about a just transition to a low-carbon future (contribution to UNESCO Inclusive Policy Lab 'Think pieces' that explores emerging issues in inclusive policies as well as offering cutting edge solutions).

Some plants use food bodies to attract ants that then provide protection from herbivory. A brief report from 1898 describes the myrmecophilic plant Leea aculeata Bl. as bearing food bodies on its young shoots, which accumulate when they are not harvested by ants. However, ant efficacy in deterring herbivores and consequences for herbivory rates remain unknown. Here we investigate (1) which ant tax

Gasoline and methanol are highly recommended for low temperature combustion (LTC) engines due to their high research octane number. However, engines fuelled with these fuels suffer from high unburned hydrocarbon (UHC) and carbon monoxide (CO) emissions at low loads, which can be improved by controlling the level of mixture stratification. This paper reports on the experimental and numerical compar

Cerebral oedema develops after anoxic brain injury. In two models of asphyxial and asystolic cardiac arrest without resuscitation, we found that oedema develops shortly after anoxia secondary to terminal depolarizations and the abnormal entry of CSF. Oedema severity correlated with the availability of CSF with the age-dependent increase in CSF volume worsening the severity of oedema. Oedema was id

Background: Targeted therapeutic mild hypercapnia may attenuate brain injury in comatose adults resuscitated from out-of-hospital cardiac arrest. Objective: To describe the study protocol and statistical analysis plan for the Targeted Therapeutic Mild Hypercapnia after Resuscitated Cardiac Arrest (TAME) trial. Design, setting, participants and interventions: TAME is a phase 3, multicentre, paralle

Background: Rectal cancer treatment has improved through important incremental surgical and oncological developments over the past decades. Localized disease is highly treatable with multimodal surgical and oncological therapy. Prognosis is dependent on several factors with tumour stage at diagnosis being the most important. Furthermore, curative treatment is highly dependent on radical surgical r

Over the past decades, the growing proliferation of international institutions governing the global environment has impelled institutional interplay as a result of functional and normative overlap across multiple regimes. This article synthesizes primary contributions made in research on institutional interplay over the past twenty years, with particular focus on publications with International En

The aim of this work was to develop a model of an integrated biomass-to-liquid process, consisting of hydrothermal liquefaction, evaporation, gasification and Fischer-Tropsch synthesis, using lignocellulosic forest residues as feedstock to produce hydrocarbons suitable for upgrade into drop-in biofuels. The energy, mass and carbon efficiencies that were achieved were 35%, 20% and 32%, respectively

Aim: Sweden´s first multidisciplinary children's advocacy centre (CAC) was founded in 2005 as a collaborative practice between child protection services, the legal system and health care in response to police-reported child abuse. CACs were introduced in the county of Skåne in 2007. The aim of the study was to describe the health of children investigated at the CAC in Lund, and to examine whether

Animal coloration is often expressed in periodic patterns that can arise from differential cell migration, yet how these processes are regulated remains elusive. We show that a female-limited polymorphism in dorsal patterning (diamond/chevron) in the brown anole is controlled by a single Mendelian locus. This locus contains the gene CCDC170 that is adjacent to, and coexpressed with, the Estrogen r
