Multicentric Longitudinal Performance Monitoring of Different Prenatal Cell‐Free DNA Screening Technologies in Belgium

Prenatal Diagnosis, Volume 46, Issue 11, Page 1771-1777, October 2026.
ABSTRACT Objective Prenatal cell‐free DNA screening is widely used to assess the risk of fetal trisomy 21, 18, and 13. Although commercial and laboratory‐developed tests (LDTs) show high accuracy in validation studies, real‐world longitudinal performance data are lacking.

When Hybrids Take an Intermediate Route: Genetic Ancestry Shapes Migration Across a Seabird Contact Zone

Molecular Ecology, Volume 35, Issue 20, October 2026.
ABSTRACT Contact zones, where related taxa breed sympatrically, provide natural laboratories for studying phylogeography and speciation. In migratory species, these systems offer unique opportunities to disentangle the relative roles of genetic and social factors in migratory behaviour.

Physicochemical Properties, Microstructure, and Sensory Analysis of Compression‐Molded Snacks Based on Modified Starch Produced by Heat‐Moisture Treatment

Starch - Stärke, Volume 78, Issue 9, September 2026.
Sweep potato starch was modified by heat‐moisture treatment to produce snacks. Snacks were produced by compression‐molding using pressure between 1–5 tons. Modified starch reduced crystallinity and enhanced texture, yielding stable products. Sensory attributes of snacks were positively correlated with the starch modification. ABSTRACT The transition to

Molecular and Serological Screening of West Nile and Usutu Virus in Birds and Humans: A Sentinel Study in Finland

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
We developed sensitive real‐time PCR assays for West Nile virus and Usutu virus to screen bird and human samples in Finland. Although no positive samples were detected, active migratory flyways and recent cases in neighbouring countries highlight the risk of future introduction and the need for continued surveillance.

Patient-based quality control: a complementary tool for external quality assessment in analytical performance evaluation

Türk Biyokimya Dergisi
Medical laboratories generate critical data for disease management, making data quality essential for patient safety. Although internal and external quality control (QC) programs aim to ensure this quality, their QC samples often lack commutability and ...

Interlaboratory consistency of SDC2 promoter methylation detection in colorectal cancer using the post-optimized materials

iScience
Summary: Fecal DNA-based Syndecan 2 (SDC2) methylation detection is a promising non-invasive strategy for early colorectal cancer (CRC) screening. In China, commercial assays for SDC2 methylation detection vary in sensitivity and specificity, yet there ...
