Cerebral perfusion metrics calculated directly from a hypoxia-induced step change in deoxyhemoglobin

open access: yesScientific Reports
Resting cerebral perfusion metrics can be calculated from the MRI ΔR2* signal during the first passage of an intravascular bolus of a Gadolinium-based contrast agent (GBCA), or more recently, a transient hypoxia-induced change in the concentration of ...

Brain-Aware Readout Layers in GNNs: Advancing Alzheimer's early Detection and Neuroimaging [PDF]

open access: yesarXiv
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive memory and cognitive decline, affecting millions worldwide. Diagnosing AD is challenging due to its heterogeneous nature and variable progression. This study introduces a novel brain-aware readout layer (BA readout layer) for Graph Neural Networks (GNNs), designed to ...

Mapping gene by early life stress interactions on child subcortical brain structures: A genome‐wide prospective study

open access: yesJCPP Advances, Volume 2, Issue 4, December 2022., 2022
Although it is well‐established that both genetics and the environment influence brain development, they are typically examined separately. This study lends novel insights into gene‐environment interplay on the developing brain as well as pointing to promising candidate loci for future mechanistic studies.

Serotonergic modulators in Alzheimer's disease: a hope in the hopeless condition

open access: yesChemistry &Biodiversity, Accepted Article.
Alzheimer disease (AD) is the main cause of dementia worldwide. AD is a progressive brain neurodegenerative disease due to genetic and environmental factors that induce a progressive accumulation of intracellular hyperphosphorylated tau protein and extracellular amyloid protein (Aβ).

Low‐field MRI: Clinical promise and challenges

open access: yesJournal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023
Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.
