Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Mini social cognition and emotional assessment: Diagnostic performance and neural correlates in behavioural‐variant frontotemporal dementia

Journal of Neuropsychology, EarlyView.
Abstract We aimed at validating the Mini Social Cognition and Emotional Assessment (Mini‐SEA) in a German cohort of mildly impaired behavioural‐variant frontotemporal dementia (bvFTD) patients and healthy controls. The Mini‐SEA comprises the Facial Emotion Recognition Test (FERT) and the Faux Pas Test (FPT) measuring Theory of Mind (ToM) abilities in ...

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)

Journal of Anatomy, EarlyView.
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, EarlyView.
ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

Hypoxic Burden in Children With Sleep‐Disordered Breathing: Determinants and Correlates

Journal of Sleep Research, EarlyView.
ABSTRACT Hypoxic burden (HB) is an emerging metric for quantifying intermittent hypoxia associated with sleep apnea, offering potential advantages over traditional measures such as the apnea‐hypopnea index (AHI). This study evaluated the distribution and clinical significance of non‐respiratory event‐specific HB in children and adolescents with ...
