Planning and governing nature-based solutions in river landscapes : Concepts, cases, and insights

Nature-based solutions (NBS), understood as actions that use ecosystem processes to address societal needs, can play important roles to future-proof river landscape development for people and nature. However, knowledge gaps exist how NBS can be planned and implemented at landscape scales. This Special Issue brings together insights and experiences from studies of assessing, planning, and implement

Genetics of quantitative traits with dominance under stabilizing and directional selection in partially selfing species

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 Fakhrizadeh—A Major Iranian Counterintelligence Failure?

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

NUDT15 polymorphism influences the metabolism and therapeutic effects of acyclovir and ganciclovir

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

South Asian Nationalisms: Concluding Reflections

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

International Forum on Policies and Practice for Transfusion of ABO and RhD Non-Identical Platelets : Summary

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

Slutrapportering av samordning av universitetets hantering av forskningsdata

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

Rapport för projekt Verksamhetskartläggning forskningsdata : Ett underprojekt till uppdrag Samordning av universitetets hantering av forskningsdata

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

The new geographies of popular music (in a pandemic) : Guilty geographies and compressed intimacies

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

Sex differences in off-target binding using tau positron emission tomography

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

The RelA/SpoT Homolog (RSH) superfamily : Distribution and functional evolution of ppgpp synthetases and hydrolases across the tree of life

RelA/SpoT Homologue (RSH) proteins, named for their sequence similarity to the RelA and SpoT enzymes of Escherichia coli, comprise a superfamily of enzymes that synthesize and/or hydrolyze the alarmone ppGpp, activator of the "stringent" response and regulator of cellular metabolism. The classical "long" RSHs Rel, RelA and SpoT with the ppGpp hydrolase, synthetase, TGS and ACT domain architecture

Structure of the Dom34-Hbs1 complex and implications for no-go decay

No-go decay (NGD) targets mRNAs with stalls in translation elongation for endonucleolytic cleavage in a process involving the Dom34 and Hbs1 proteins. The crystal structure of a Schizosaccharomyces pombe Dom34-Hbs1 complex reveals an overall shape similar to that of eRF1-eRF3-GTP and EF-Tu-tRNA-GDPNP. Similarly to eRF1 and GTP binding to eRF3, Dom34 and GTP bind to Hbs1 with strong cooperativity,

Mechanism of tetracycline resistance by ribosomal protection protein Tet(O)

Tetracycline resistance protein Tet(O), which protects the bacterial ribosome from binding the antibiotic tetracycline, is a translational GTPase with significant similarity in both sequence and structure to the elongation factor EF-G. Here, we present an atomic model of the Tet(O)-bound 70S ribosome based on our cryo-electron microscopic reconstruction at 9.6-Å resolution. This atomic model allow

GTPases IF2 and EF-G bind GDP and the SRL RNA in a mutually exclusive manner

Translational GTPases (trGTPases) are involved in all four stages of protein biosynthesis: initiation, elongation, termination and ribosome recycling. The trGTPases Initiation Factor 2 (IF2) and Elongation Factor G (EF-G) respectively orchestrate initiation complex formation and translocation of the peptidyl-tRNA:mRNA complex through the bacterial ribosome. The ribosome regulates the GTPase cycle

Thermodynamic Characterization of ppGpp Binding to EF-G or IF2 and of Initiator tRNA Binding to Free IF2 in the Presence of GDP, GTP, or ppGpp

In addition to their natural substrates GDP and GTP, the bacterial translational GTPases initiation factor (IF) 2 and elongation factor G (EF-G) interact with the alarmone molecule guanosine tetraphosphate (ppGpp), which leads to GTPase inhibition. We have used isothermal titration calorimetry to determine the affinities of ppGpp for IF2 and EF-G at a temperature interval of 5-25 °C. We find that

GTP-dependent structural rearrangement of the eRF1:eRF3 complex and eRF3 sequence motifs essential for PABP binding

Translation termination in eukaryotes is governed by the concerted action of eRF1 and eRF3 factors. eRF1 recognizes the stop codon in the A site of the ribosome and promotes nascent peptide chain release, and the GTPase eRF3 facilitates this peptide release via its interaction with eRF1. In addition to its role in termination, eRF3 is involved in normal and nonsense-mediated mRNA decay through its

An ancient family of SelB elongation factor-like proteins with a broad but disjunct distribution across archaea

Background: SelB is the dedicated elongation factor for delivery of selenocysteinyl-tRNA to the ribosome. In archaea, only a subset of methanogens utilizes selenocysteine and encodes archaeal SelB (aSelB). A SelB-like (aSelBL) homolog has previously been identified in an archaeon that does not encode selenosysteine, and has been proposed to be a pyrrolysyl-tRNA-specific elongation factor (EF-Pyl).
