Exploring the Mechanism of Postpartum Cognitive Dysfunction in a Preeclampsia Rat Model via Multimodal Imaging

open access: yesThe FASEB Journal, Volume 40, Issue 19, 15 October 2026.
This schematic illustrates an L‐NAME‐induced preeclampsia (PE) rat model generated via L‐NAME administration to pregnant dams, wherein Morris water maze assessments confirmed progressive postpartum cognitive dysfunction that emerged at 10 days post‐partum and deteriorated further at 1 and 3 months post‐partum. Multimodal magnetic resonance imaging (MRI)

The underlying neurobiology of social isolation and loneliness in middle‐older adults: A systematic review

open access: yesAlzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract Social isolation and loneliness are distinct but overlapping dementia risk factors, though their underlying neurobiological mechanisms remain unclear. A systematic search identified 42 studies examining social isolation, loneliness, and neurobiological outcomes in middle‐aged and older adults, including structural and functional neuroimaging ...

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

open access: yesAdvanced Materials, Volume 38, Issue 44, 7 August 2026.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

Real‐world assessment of a deep learning neural network algorithm for prostate cancer detection in MRI using true de novo data

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Deep‐learning neural network algorithms for detecting prostate cancer in MRI have proliferated in the literature. However, out of 30+ studies published since the PROSTATEx challenge, no studies tested the performance of their algorithm against using true external image data sets (studies came from an outside institution that did not

k as a quantitative indicator of calf muscle perfusion at peak exercise [PDF]

open access: yesJournal of Cardiovascular Magnetic Resonance, 2014
Background Quantitative contrast enhanced MRI (CE-MRI) may be valuable for calf perfusion assessment in peripheral arterial disease (PAD). The Kety equation describes the dynamic relationship between the concentration of gadolinium (Gd) in tissue and in arterial blood. ktrans is the rate at which Gd enters the interstitial space and it is determined by

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...
