Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Experimental Extracorporeal Circulation System: A Pilot Study in Rats

open access: yesArtificial Organs, EarlyView.
A miniature extracorporeal circulation (ECC) system was developed for reproducible rodent studies. This system incorporates an integrated heat exchanger and a silicone membrane oxygenator within a double‐lumen circuit, resulting in an ultralow priming volume of < 1.5 mL.

Distinctly altered TRPC3 and TRPC6 expression patterns in human Alzheimer's disease cortex and hippocampus

open access: yesBrain Pathology, EarlyView.
Divergent remodeling of TRPC channels occurs in Alzheimer's disease, with TRPC3 increased in neurons and reactive astrocytes and TRPC6 reduced in pyramidal neurons. These alterations may contribute to calcium dysregulation, neuroinflammation, and synaptic dysfunction during AD progression.

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

open access: yesBrain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.
