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.

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 ...

Growing evidence suggests the specific systems for emotional information maintenance and processing in working memory, highlighting the role of cognitive domains in emotional awareness. The question of neural basis of social-emotional processing in working memory remains open. We hypothesized that the neural systems supporting working memory for emotional processing may rely on shared ‘core’ networks ...

Copper–organic compounds are being investigated as antitumor candidates. Besides their efficacy as cytotoxic agents alone, the oxidative potential of electrochemical Cu2+-to-Cu1+ transition emerges as an attractive approach for elimination of tumor cells otherwise resistant to chemotherapy. To minimize side effects of the potent oxidative burst upon Cu(II) reduction, the metal cations should be delivered to the ...

The recalcitrance of tumors to photodynamic therapy (PDT) has been linked to PDT-induced activation of survival pathways in sublethally afflicted cancer cells that modulate cellular responses to oxidative stress and damage. Survival signaling manifests in regions of the tumor where the tumor cells are insufficiently photosensitized or subjected to inadequate fluence rates. The survival signaling ...

INTRODUCTION: Robust and objective quantification of ophthalmic and retroorbital structures from standard neuroimaging is an accessible but still untapped resource for clinical assessment. Current approaches mostly rely on subjective manual measurements, introducing variability and limiting clinical integration. We developed and validated an automated ocular morphometrics pipeline enabling diagnostic precision through standardised orbital measurements.
METHODS: The presented pipeline consists of: ...

Background. Preeclampsia (PE) complicates 2–8% of pregnancies and involves placental hypoxia and HIF-pathway activation, especially in early-onset PE (eoPE). Chemical mimetics like cobalt(II) chloride (CoCl2) and oxyquinoline derivatives model trophoblast hypoxia in vitro, yet their fidelity in recapitulating PE gene profiles remains unclear. Integrating patient tissue analyses with experimental models may reveal common markers and ...
