Lek mellan hundägare och hund stärker den emotionella närheten mellan dem mer effektivt än träning. Forskare vid Linköpings universitet undersökte sambandet mellan lekaktiviteter och relationen mellan hund och ägare genom två studier. I den första studien (n=2940) identifierades signifikanta samband mellan både lek och träning och alla tre mätdimensioner av hundens relationsscala (p<0,0001). I den andra studien tilldelades 408 deltagare tre grupper under fyra veckor: lek, träning eller kontroll. Endast lekgruppen visade signifikant förbättrad emotionell närhet efter behandlingsperioden (p=0,018), vilket påvisar en kausal effekt. Resultaten tyder på att lek har större påverkan än träning för att stärka relationskvaliteten. För aktörer inom hundhälsa och välfärdsmarknad relevanta detta för produktutveckling och rådgivning — vetenskapligt underlag för att rekommendera lek framför träningsfokus kan öka efterfrågan på lekprodukter och välfärdsprogram baserade på detta fynd.

FORCE-panelen för SNP-typning visar lovande resultat i rättsmedicinskanalys, men kräver standardisering av laboratorieprotokoll för bred implementering. Linköpings universitet och 14 internationella laboratorier testade fyra tillverkarutvecklade berikningsmetoder på 12 DNA-prover med varierande kvalitet. Alla fyra tillvägagångssätt lyckades producera fullständiga SNP-genotyper från högkvalitativt material. Dock påvisades signifikanta skillnader mellan metoderna — särskilt gällande läsantal och berikningsmetod påverkade anropshastigheten. Robust SNP-återhämtning observerades vid 0,3 ng DNA-input över samtliga metoder, medan amplikonbaserad analys presterade vid så låga halter som 0,03 ng. Fångstmetoder och enkel primärförlängning gav konsekvent höga anropshastigheter från degraderat DNA. Resultaten indikerar att optimering av laboratoriespecifika parametrar kan reducera variation och möjliggöra jämlik adoption av SNP-metoder inom rättsmedicinskanalys.

Forskare vid Sahlgrenska Universitetssjukhuset och Göteborgs universitet kartlade proteinnätverken i hjärtmuskelprover från patienter med två typer av kardial amyloidosö — ATTR och ALλ. Studien identifierade hur ljuskedjefibril förs in i makrofager genom makropinokytoskytning och orsakar mitokondriell toxicitet, samt hur ATTR ansamlas extracellmässigt. Genom proteinkvantiering och nätverkstopologi kunde forskargruppen peka ut potentiella sjukdomsmarkörer. Analyserna utgick från känsligt tillgängligt biopsimaterial från hjärtamyloidospatienter. Även om studien är baserad på robusta urvalskriterier krävs validering i större kohorter. För bolag som utvecklar diagnostik eller läkemedel mot kardial amyloidosö erbjuder dessa molekylära profiler nya angreppspunkter för biomarkörselekton och terapiutveckling inom en marknad med begränsad konkurrens.

En ny SCN9A-mutation hos isländsk familj öppnar vägen för bättre förståelse av smärtreglering och potentiella läkemedelsmål. En 73-årig man och hans två bröder bär en unik genetisk kombination — en tidigare känd mutation (p.Lys1659Ter) tillsammans med en helt ny deletion (c.417-15_4174-14delAT) som tar bort exon 23 och 18 aminosyror från natriumkanalen. Genom helgenomssekvensering bekräftade forskare vid Sahlgrenska och University of Iceland att denna sammansatt heterozygoti förklarar familjens medfödda smärtokänslighet utan att påverka andra neurologiska funktioner nämnvärt. Fyndet är relevant för läkemedelsutvecklare som söker selektiva SCN9A-hämmare för smärtbehandling. Mutationen visar exakt vilka proteindomäner som är icke-essentiella för normal neurologisk funktion, vilket reducerar risken för biverkningar vid framtida terapier. Denna precision gör studien värdefull för såväl målidentifiering som säkerhetsprofil.
