Recurrent self-fertilization is thought to lead to reduced adaptive potential by decreasing the genetic diversity of populations, thus leading selfing lineages down an evolutionary “blind alley.” Although well supported theoretically, empirical support for reduced adaptability in selfing species is limited. One limitation of classical theoretical models is that they assume pure additivity of the f
The assassination of Iranian top nuclear scientist Mohsen Fakhrizadeh is one of numerous assassinations in Iran conducted by foreign powers ever since 2007. In the past six months, assassins have in addition to Fakhrizadeh also been able to kill Al-Qaida’s no. 2 on Iranian soil. The three most important organizations in the Iranian intelligence community are the Ministry of Intelligence, as well a
Nucleobase and nucleoside analogs (NNA) are widely used as anti-viral and anti-cancer agents, and NNA phosphorylation is essential for the activity of this class of drugs. Recently, diphosphatase NUDT15 was linked to thiopurine metabolism with NUDT15 polymorphism associated with drug toxicity in patients. Profiling NNA drugs, we identify acyclovir (ACV) and ganciclovir (GCV) as two new NNAs metabo
In this concluding commentary, the overall theme of the special issue as well as the collective contribution of the individual articles are addressed and elaborated upon. In particular, it focuses on the manifold commonalities that exist between South Asian states—both in terms of shared traits or dynamics and the recurrent attribution of negative connotations to neighboring states—and how these i
Transfusion of ABO major incompatible platelets (where the recipient has antibodies against the ABO group of the transfused platelets) has been shown to be associated with lower platelet count increments following transfusion [1], although this does not appear to translate to a difference in bleeding outcomes [2]. Transfusion of minor ABO incompatible platelets (where the suspending plasma of the
Detta är slutrapportering av rektorsuppdraget Samordning av universitetets hantering av forskningsdata, Dnr STYR 2019/295. Rapporten beskriver forskningsdataområdets disruptiva natur och dess relation till e-infrastrukturområdet, hur ett samordningsuppdrag formaliserades och med tiden formerades, vilka underprojekt som initierats och delområden som bevakats, föreslår en färdplan inför nästa steg i
Projektet har gjort en kartläggning över Lunds universitets förmågor att stötta god forskningsdatahantering med hjälp av verksamhetsarkitekturella metoder. Kartläggningen grundar sig på intervjuermed forskare, workshops med forskare, intervjuer med expertroller och stödorganisationspersonal,samt enkät till stödorganisationer. Analyser av insamlat material har resulterat i grafiska representationer
In this paper, I analyse developments in the relationship between popular musicians and their audiences that have intensified during the COVID-19 pandemic of 2020–21. The first, guilty geographies, concerns musicians and music venues becoming increasingly reliant on charitable audience support, appealing to fans’ ethical consciences through the crowdfunding (or fan-funding) model. The second, comp
Purpose: Off-target binding in the skull and meninges is observed in some subjects undergoing tau positron emission tomography (PET) and could potentially differ between men and women. In this study we elucidate sex differences in tau off-target binding using three different tau PET tracers. Methods: 541 cognitively unimpaired amyloid-β negative participants underwent tau PET using [18F]flortaucip
Petroleum, contains proportions of contaminants such as sulfur, nitrogen, oxygen, and metals, such as nickel, iron, copper, sodium, and vanadium. Particularly, contaminants containing sulfur cause problems during handling, transportation, and the use of the their derivatives. This work had the goal of cracking the heavy crude oil molecules by reacting these molecules with tetralin and simultaneous
In the past, the identification of myocardial fibrosis was only possible through invasive histologic assessment. Although endomyocardial biopsy remains the gold standard, recent advances in cardiac imaging techniques have enabled non-invasive tissue characterization of the myocardium, which has also provided valuable insights into specific disease processes. The diagnostic accuracy, incremental yi
Aim: The aim was to determine body composition and growth in preterm infants based on two different feeding regimens and to assess how standard and individual fortification (IF) affect energy and protein intake. Body composition was assessed at full term and at four months corrected age. Methods: Sixty preterm infants born before gestational week 32 were randomized either to IF of mother’s breast
Emissions from aviation are expected to grow. With evidence that the International Civil Aviation Organization’s Carbon Offsetting and Reduction Scheme for International Aviation is an inadequate mitigation mechanism, there is interest in upscaling the sector’s climate-related policies. This paper reviews potential aviation emissions mitigation policies against the background of emerging complexit
Secondary mitral regurgitation (MR) occurs despite structurally normal valve apparatus due to an underlying disease of the myocardium leading to disruption of the balance between tethering and closing forces with ensuing failure of leaflet coaptation. In patients with heart failure (HF) and left ventricular dysfunction, secondary MR is independently associated with poor outcome, yet prognostic ben
Atherosclerosis is a lipid-driven, chronic inflammatory disease. In spite of efficient lipid lowering treatments, such as statins and PCSK9 inhibitors, patients, especially those with elevated inflammatory biomarkers, still have a significant residual cardiovascular disease risk. Novel drugs targeting inflammatory mediators are needed to further reduce this residual risk. Agonistic immune checkpoi
Background: Stroke and dementia are interrelated diseases and risk for both increases with age. Even though stroke incidence and age-standardized death rates have decreased due to prevention of stroke risk factors, increased utilization of reperfusion therapies, and other changes in healthcare, the absolute numbers are increasing due to population growth and aging. Objective: To analyze predictors
