DIAGNOSTIC ACCURACY OF VISUAL INSPECTION WITH ACETIC ACID FOR CERVICAL CANCER SCREENING AMONG WOMEN LIVING WITH HUMAN IMMUNODEFICIENCY VIRUS IN OSOGBO, NIGERIA

A preprint study evaluates how accurately visual inspection with acetic acid (VIA) detects cervical cancer in women living with HIV in Nigeria, compared to HPV DNA testing. The findings matter because VIA is the feasible screening method in resource-limited settings, despite HPV DNA being the standard.

Change of prognostic nutritional index after three months of initial hemodialysis is a predictor of long-term outcomes for patients with uremia

A new study from medRxiv investigates whether changes in the Prognostic Nutritional Index (PNI) during the first three months of hemodialysis better predict long-term outcomes in uremia patients than baseline measurements. The research addresses the early instability of nutritional status in dialysis initiation.

A sex-specific regulator expands the embryonic ocular field to generate a novel visual system

This preprint reports that the male-specific turbanate eyes of mayflies arise through redeployment of ancestral retinal developmental programs, controlled by a sex-specific regulator that expands the embryonic ocular field. The finding reveals how new morphological structures can evolve by co-opting existing genetic circuits in new developmental contexts.

Blastema cells exhibit intrinsic migratory capacity but fail to induce osteoblast off-bone migration during Zebrafish fin regeneration

A bioRxiv preprint reports that blastema cells from regenerating zebrafish fins have intrinsic migratory capacity, but the presence of injury or blastema alone is insufficient to trigger osteoblast migration off the bone. The study sheds light on cellular mechanisms underlying epimorphic fin regeneration.

Why architecture matters: Controlling gene expression through design

A new bioRxiv preprint examines how promoter architecture, not just regulator chemistry, governs the performance of TetR-based inducible gene expression systems in mammalian cells. The study shows that bidirectional circuit designs impose a trade-off between output strength and regulatory control, with implications for synthetic biology and gene therapy design.

Mimicking two posttranslational modifications associated with oxidative stress affords phase separation of vimentin

This preprint from bioRxiv reports that mimicking two oxidative-stress-related posttranslational modifications on the intermediate filament protein vimentin drives its phase separation into biomolecular condensates. The work provides mechanistic insight into how oxidative stress remodels the cytoskeleton through vimentin's single cysteine residue, C328.

Tracking emotional interference over time: Differential effects of dorsolateral and ventromedial prefrontal stimulation

This bioRxiv preprint examines how emotional interference evolves over time and which prefrontal regions regulate it, using brain stimulation in healthy participants. The study found differential roles for dorsolateral and ventromedial prefrontal cortex in managing emotional distraction during working memory and task-switching.

Healed predation scar on a Cambrian apex predator

A new fossil study reports a healed predation scar on a Cambrian apex predator, providing the first direct evidence that large, soft-bodied animals at high trophic levels were preyed upon during the Cambrian explosion. This finding fills a gap in fossil evidence for higher-level trophic interactions in early animal ecosystems.
