A new review finds that curcumin, the active ingredient in turmeric, can suppress the immune attacks that destroy nerve tissue in multiple sclerosis, at least in animal models. The discovery could accelerate development of oral therapies for MS, a disease affecting nearly 3 million people globally and representing a multi-billion-dollar market opportunity.EN

Researchers have developed a new method to deliver gene editors into cells using modified virus-like particles, addressing a major bottleneck in gene therapy development. The advance could accelerate clinical applications and reduce manufacturing costs for genetic medicines across multiple disease areas.EN

Artificiell intelligens möjliggör snabbare variantidentifiering av SARS-CoV-2. Forskare från Nanjing University och KTH utvecklade ett klassificeringsystem som kombinerar direktkopplingsanalys, visuell kartläggning och neurala nätverk för att särskilja virusvarianter från genomsekvenser. Systemet klassificerar varianterna Alpha, Delta, Omicron och övriga genom att analysera epistatiska kopplingar mellan mutationer — växelverkan mellan genplatser som påverkar viral evolution. Modellen nådde ett vägtat F1-värde på inte specificerat och ett område under kurvans värde nära 1 vid testning. I tidsbaserad validering över evolutionär tid behöll systemet prediktiv förmåga med ett F1-värde på 87,85 procent. Tekniken är relevant för laboratorier och diagnostikleverantörer som behöver automatisera variantkallning när nya SARS-CoV-2-stammar cirkulerar. Maskininlärningsmetoden erbjuder en skalbar väg att övervaka viral evolution utan manuell sekvensklassificering.

VMAT-planering för bröstcancer med lymfkörtelbehandling saknar standardiserad strategi — ett problem som kan förlänga utvecklingstiden för nya doserings­protokoll och skapa leverantörsberoende. En europeisk arbetsgrupp analyserade 22 behandlingsplaner från 25 institutioner och identifierade fem effektiva planeringsmetoder för komplex lymfkörtelomfattning. Resultaten visar stor variation: hjärtdoser spände från 1,5 till 9,5 Gy, ipsilateral lungdos från 12,0 till 17,3 Gy. Målvolymerna fick mellan 49,7–52,1 Gy (lymfkörtel) respektive 51,9–54,1 Gy (bröst), med simultanintegrerad boost på 61,5–66,5 Gy. Universitetet i Hamburg ledde studien tillsammans med sex europeiska centrum. Resultaten är relevanta för radiologikliniker som söker optimeringsvägar, för systemleverantörer som utvecklar planeringsalgoritmer och för kliniker som utvärderar kostnadseffektivitet när olika institutioner använder divergerande metoder.
