Objective: Previous research has suggested an association between physical activity (PA), joint function, and molecular biomarkers, but more studies are needed. The aim of this study was to explore the associations between PA or self-reported joint function and molecular biomarkers of cartilage and inflammation in individuals with hip and/or knee osteoarthritis (OA). Specific objectives were to ex
The bioactivity, biological fate and cytotoxicity of nanomaterials when they come into contact with living organisms are determined by their interaction with biomacromolecules and biological barriers. In this context, the role of symmetry/shape anisotropy of both the nanomaterials and biological interfaces in their mutual interaction, is a relatively unaddressed issue. Here, we study the interacti
In the Ordovician limestone of the Thorsberg quarry (South Sweden), about 130 meteorites have been found. Among the extraterrestrial material, several terrestrial Cr-spinels and zircons have been found too. In particular, in the interval 416–447 cm above the Arkeologen bed, terrestrial Cr-spinels, compositionally different from previous studied Cr-spinels of the same sequence, are present. Previou
Biological nitrogen fixation (BNF) from grain legumes is of significant importance in global agricultural ecosystems. Crops with BNF capability are expected to support the need to increase food production while reducing nitrogen (N) fertilizer input for agricultural sustainability, but quantification of N fixing rates and BNF crop yields remains inadequate on a global scale. Here we incorporate tw
We have implemented and evaluated a secondary organic aerosol scheme within the chemistry transport model TM5-MP in this work. In earlier versions of TM5-MP the secondary organic aerosol (SOA) was emitted as Aitken-sized particle mass emulating the condensation. In the current scheme we simulate the formation of secondary organic aerosol from oxidation of isoprene and monoterpenes by ozone and hyd
Various strategies are being suggested to solve the challenges in the food system, such as changing the source of nutrients, including the use of non-traditional food sources such as insects. Although insects are promoted as a cheap and sustainable source of protein, consumers are reluctant to eat them. The mycoproteins produced by fungi, on the other hand, are very well received and appreciated b
We have used combined quantum mechanical and molecular mechanical (QM/MM) calculations to study the reaction mechanism of nitrogenase, assuming that none of the sulfide ligands dissociates. To avoid the problem that there is no consensus regarding the structure and protonation of the E4 state, we start from a state where N2 is bound to the cluster and is protonated to N2H2, after dissociation of H
Background: In clinic, a subjective visual estimation of a patient’s general health often guides interventions, yet little is known of how this assessment relates to objectively measured frailty. Aims: To characterize the relationship between these two assessments and explore the implication of discordance. Methods: The study was performed in the OPRA cohort of 75-year old community-dwelling women
Avhandlingens titel: ”Assessment of the right heart in pulmonary hypertension”Målet med avhandlingen var att undersöka de högersidiga hjärtrummens storlek ochfunktion hos patienter med förhöjt tryck i lungkretsloppet, pulmonell hypertension(PH). Detta utfördes i huvudsak med hjärtultraljud (ekokardiografi), men undersök -ningsmodaliteterna magnetkameraundersökning av hjärtat (MR) och högersidighjä
This year marks the inauguration of the annual Editors’ Choice Award and the Readers’ Choice Award, each presented for outstanding original papers and review articles published in the Journal of Comparative Physiology A. The winners of the 2022 Editors’ Choice Award were determined by vote of the Editorial Board for the most highly recommended papers published in Volume 207 in 2021. They are ‘Visu
Algal blooms constitute an emerging threat to global inland water quality, yet their spatial and temporal distribution at the global scale remains largely unknown. Here we establish a global bloom database, using 2.91 million Landsat satellite images from 1982 to 2019 to characterize algal blooms in 248,243 freshwater lakes, representing 57.1% of the global lake area. We show that 21,878 lakes (8.
Strontium titanate (STO), with a wide spectrum of emergent properties such as ferroelectricity and superconductivity, has received significant attention in the community of strongly correlated materials. In the strain-free STO film grown on the SrRuO3 buffer layer, the existing polar nanoregions can facilitate room-temperature ferroelectricity when the STO film thickness approaches 10 nm. Here we
Habitat preferences and foraging strategies affect population-level space use and are therefore crucial to understanding population change and implementing spatial conservation and management actions. We investigated the breeding season habitat preference and foraging site fidelity of the under-studied and threatened, Baltic Sea population of Caspian Terns (Hydroprogne caspia). Using GPS devices,
Since its origins in the 19th century, the SSE has instantiated a strong focus on the practice of solidarity alongside other political claims, thus supporting the idea that ‘another world is possible’, and economic transformation should accompany shifts in social relations (Laville and Salmon, 2014). However, despite its transformative poten-tial, solidarity has been the ‘silent S’ in the SSE, in
Vertically oriented graphene (VG) has attracted attention for years, but the growth mechanism is still not fully revealed. The electric field may play a role, but the direct evidence and exactly what role it plays remains unclear. Here, we conduct a systematic study and find that in plasma-enhanced chemical vapor deposition, the VG growth preferably occurs at spots where the local field is stronge
This article explores the role of values (Gehman, et al. 2013; Daskalaki et al. 2019) in the emergence and evolution of Grassroots Innovations (GIs) in the context of Argentina GIs are developed by communities as a means to overcome social exclusion while at the same time strive for a better future. GIs experience an intrinsic challenge: while they address social injustice, they are not able to ad
Whilst mission-driven or hybrid organisations take various forms, they allshare the challenge of navigating contradictory goals to combine social and commercial benefits to different degrees (Shepherd et al., 2019). Social Enterprises (SEs) are a form of mission-driven organisation that prioritise meeting social needs by bringing goods, services or other benefits to economically or politically exc
Detta är en sammanställning av arkiv och information som Historiska museet vid Lunds universitet har idag (2022) avseende samiska mänskliga kvarlevor samt gipsavgjutningar som museet förvaltar åt Lunds universitet. I rapporten ingår åtta samiska kvarlevor. Alla kvarlevor är inkomna till Lunds universitet under 1800-talet. Sju av kvarlevorna kommer från den svenska sidan av Sápmi, en kvarleva komme
This article explores complementary currencies (CC) that work on the basis of community credit schemes in Argentina, a country often referred to as a laboratory in terms of monetary exploration. In contrast to alternative community-based monetary systems created in the global North, CC developed in the global South usually pursue the creation of supplementary currency circulation in order to addre
