Longer product lifetimes are promoted by the EU's Circular Economy Action Plan, but incentivising longer lifetimes could also result in trade-offs between different environmental impacts for some product categories. LED lamps are still experiencing improvements in efficacy and material design, which raises questions about whether longer lifetimes are desirable from an overall environmental perspec
Bacteria and fungi are the two principal decomposer groups in soils, determining rates of biogeochemical cycling. Rewetting of dry soils induces enormous dynamics in biogeochemistry. Bacteria have been shown to exhibit large variation in growth over time upon drying-rewetting (D/RW), however, in studies to date, fungal growth has shown limited responsiveness. Here we investigated whether fungal gr
Flera studier har på senare år visat att den läkare som själv blir sjuk upplever sig försatt i en särskilt problematisk situation. Ett sätt att öka förståelsen för den sjukdomsdrabbade läkarens upplevda dilemma kan vara att närstudera läkares sjukdomsnarrativ. I denna artikel uttolkas tre skriftliga vittnesmål av läkare med morfinmissbruk, med särskild tonvikt på Michail Bulgakovs semifiktiva nove
Lunds historia innehåller många medicinhistoriska händelser. Medicinhistoria som akademisk disciplin är dock inte endast deskriptiv utan även analyserande. Flera institutioner vid Lunds universitet bedriver medicinhistorisk forskning från olika utgångspunkter. Medicinhistoria är ett viktigt ämne för förståelsen av dagens medicin och denna översikt vill visa varför och hur ämnet behandlas vid Lunds
Droplet volume and temperature affect contact angle significantly. Phase change heat transfer processes of nanofluids – suspensions containing nanometre-sized particles – can only be modelled properly by understanding these effects. The approach proposed here considers the limiting contact angle of a droplet asymptotically approaching zero-volume as a thermophysical property to characterise nanofl
’Patografi’ är beteckningen på en relativt ung och snabbt växande litterär genre. Syftet med denna artikel är att introducera den patografiska genren och att lämna ett bidrag till förståelsen av dess historiska uppkomst. Tre omvälvningar i skolmedicinen vid 1800-talets slut och 1900-talets början lyfts fram som betydelsefulla för den patografiska genrens framväxt: sanatoriernas tillkomst, stigmati
Recent large-scale genetic studies have allowed for the first glimpse of the effects of common genetic variability in dementia with Lewy bodies (DLB), identifying risk variants with appreciable effect sizes. However, it is currently well established that a substantial portion of the genetic heritable component of complex traits is not captured by genome-wide significant SNPs. To overcome this issu
Background: In problem gambling, recent years have seen an expansion of online gambling in treatment-seeking patients. Television advertising may promote risky gambling, and this study aimed to assess gambling-related advertisements, with respect to potentially risky messages, in a country with high rates of online gambling among treatment seekers, for online casino particularly in treatment-seeki
Background: Being foreign born, i.e. not born in the reception country or belonging to an ethnic minority, has been described as a risk factor of problem gambling, although research so far has been inconclusive. Also, there is limited knowledge about whether this association is caused by differing gambling norms. The present study aimed to study whether foreign origin is associated with problem ga
One of the most ubiquitous techniques within attosecond science is the so-called reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). Originally proposed for the characterization of attosecond pulses, it has been successfully applied to the accurate determination of time delays in photoemission. Here, we examine in detail, using numerical simulations, the effect
Complement component C3 is central to the complement system, a humoral effector mechanism of innate immune defense. When activated, C3 covalently binds to target particles, marking them for uptake and clearance by phagocytosis. We now show that C3 also exists within the cytosol where it interacts with ATG16L1, and is therefore involved in the intracellular clearance and recycling of material by ma
Aims: Peptide receptor radionuclide therapy (PRRT) is in clinical use today to treat metastatic neuroendocrine tumors. Infused, radiolabeled, somatostatin analog peptides target tumors that are killed by irradiation damage. The peptides, however, are also retained in kidneys due to glomerular filtration, and the administered doses must be l
Aiming at the fact that the function of gas distributor is often neglected in the case of high viscosity conditions, a novel spherical micro-orifice gas distributor was proposed and investigated experimentally in water system and non-Newtonian viscous system, respectively. The comparisons of gas–liquid dispersion and mass transfer performance between novel spherical micro-orifice gas distributor a
Objectives: The aim of this study was to evaluate the effect of fractional flow reserve (FFR)–guided revascularization compared with culprit-only percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) on infarct size, left ventricular (LV), function, LV remodeling, and the presence of nonculprit infarctions. Background: Patients with STEMI with
Background: Prognoses of most adult Hodgkin lymphoma (HL) patients are excellent; most of them can achieve permanent remission that can be considered cured. However, many are under-treated or over-treated by standard modern therapies. An accurate determination of prognosis may allow clinicians to design personalised treatment according to individual risk of disease progression and survival. Lympho
On-surface synthesis has emerged in the last decade as a method to create graphene nanoribbons (GNRs) with atomic precision. The underlying premise of this bottom-up strategy is that precursor molecules undergo a well-defined sequence of inter- and intramolecular reactions, leading to the formation of a single product. As such, the structure of the GNR is encoded in the precursors. However, recent
Background: The uterine environment may influence telomere length at birth, which is essential for cellular function, aging, and disease susceptibility over the lifespan. However, little is known about the impact of toxic chemicals on early-life telomeres. Therefore, we assessed the potential impact of multiple toxic metals on relative telo
