Long-duration spaceflight affects otolith-mediated ocular counter-roll (OCR) and brain function, but the relationship between these changes is unclear. This study examines whether OCR changes correlate with functional connectivity (FC) changes in the vestibular network in the same cosmonauts after a long-duration (6-month) spaceflight mission. Using a human vestibular atlas, we found that changes in FC between the right operculum (OP2_PIVC) and inferior parietal lobule (IPL, area PGp and PGa) were positively correlated with OCR changes. First-time flyers showed a greater decrease in OCR, linked to more significant FC reductions. Irrespective of the OCR, increased FC was observed postflight between the left visual cingulate cortex (CSv) and the anterior cingulate cortex (ACC, area 33), superior parietal lobule (SPL, area 5C), and thalamus (pulvinar), and between the right OP2_PIVC and SPL (area 5Ci). Secondly, decreased FC was observed between the left OP2_PIVC and the IPL (PGp) and SPL (area 7A). Additionally, increased FC postflight was observed between the left lateral sensorimotor area (LSM) and IPL (area PGp), and between the right lateral visual area (LVA) and cerebellum (Crus 1, Lobule VI). These findings suggest sensory reweighting and sensory system reorganization after long-duration spaceflight.

Preeclampsia (PE) is a severe obstetric complication caused by chronic placental ischaemia. Genome-wide profiling of microRNA isoforms in two trophoblast hypoxia models (CoCl2 and the oxyquinoline derivative neuradapt, BeWo b30 cells) and clinical PE samples (placental tissue, syncytiotrophoblast vesicles) revealed concordant downregulation of hsa-miR-143-3p isoforms. Under a strict fold-change threshold, the canonical isoform (21 nt) ...

Deciphering the evolutionary history of genes is foundational for biomedical research, enabling the identification of compensatory mutations in disease-associated genes and the selection of evolutionarily relevant model organisms. However, challenges of multi-isoform handling, the presence of incomplete genomes/proteomes initial datasets, and problems of evolutionary history representation are still present. To address these issues, we introduce ...

Inhibition of the PD-1/PD-L1 axis has become a clinical standard across multiple malignancies, yet durable benefit remains restricted to selected settings, and many biologically rational combinations fail to maintain clinical benefit in late-phase evaluation. This structured, registry-derived narrative review, supported by expert-guided interpretation, was designed to identify the most clinically meaningful development directions among strategies ...

Whole-slide histology images (WSIs) can exceed 100 k × 100 k pixels, making direct pixel-level segmentation infeasible and requiring patch-level classification as a practical alternative for downstream WSI segmentation. However, most approaches either treat patches independently, ignoring spatial and biological context, or rely on deep graph models prone to oversmoothing and loss of local tissue ...

Glioblastomas are the most prevalent primary brain tumors and are associated with a dramatically poor prognosis. Despite an intensive treatment approach, including maximal surgical tumor removal followed by radio- and chemotherapy, the median survival for glioblastoma patients has remained around 18 months for decades. Glioblastoma is distinguished by its highly complex mechanisms of immune evasion ...

Motor imagery (MI) allows individuals to mentally simulate movements without execution, engaging neural pathways that overlap with those used during real actions. However, how imagery perspective influences corticospinal excitability across different effectors remains unclear. Using neuronavigated transcranial magnetic stimulation (TMS), we compared kinesthetic (KMI), first-person visual (VMI-1PP), and third-person visual (VMI-3PP) imagery of elbow flexion-extension ...

Introduction:
While self-referential attention is thought to enhance interoceptive sensitivity, its effect on cardiac modulation of corticospinal excitability remains unexplored. This pilot study investigated how viewing one’s own face (self-face processing) modulates the cardiac-phase coupling of motor output and whether this heart-brain coupling depends on interoceptive accuracy (heartbeat perception).
Methods:
In 15 healthy adults, motor-evoked potentials (MEPs) were ...

Background: Neuroblastoma (NB), a transcriptionally driven pediatric malignancy, exhibits a remarkable clinical and biological heterogeneity. Two major subtypes, adrenergic and mesenchymal, are differentially governed by distinct subsets of transcription factors that constitute the core regulatory circuitry (CRC). The adrenergic subtype is often associated with MYCN amplification and is particularly aggressive and therapy-resistant, underscoring the need ...
