Predictors of depressive symptoms and depression in women with previous pregnancy loss

British Journal of Clinical Psychology, EarlyView.
Abstract Objectives Depressive symptoms are common in females after pregnancy loss. However, research on risk factors for developing a clinical depressive episode remains limited and with inconsistent findings. This study examined the association of demographic variables (like age), pregnancy‐related factors (like number of miscarriages or stillbirths),

Dose‐dependent impairment of brain functional and microstructural connectivity during leukaemia chemotherapy

British Journal of Haematology, EarlyView.
Prospective functional MRI brain and neurocognitive assessments were performed serially during intensive chemotherapy for a cohort of adults with newly diagnosed acute myeloid leukaemia to elucidate ‘chemobrain’ language phenomena. At completion of consolidation, significant reductions in functional and microstructural connectivity were observed ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Quantitative susceptibility mapping (QSM) evaluation of infantile neuroaxonal dystrophy

BJR|case reports, 2019
We present the first case of twins with infantile neuroaxonal dystrophy evaluating brain iron deposition using quantitative susceptibility mapping (QSM). A 6-year-old boy who was normal at birth had psychomotor regression and hypotonia from 2-years-old.

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 3031-3043, May 2026.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Laboratory Tests of Low Density Astrophysical Equations of State

, 2012
Clustering in low density nuclear matter has been investigated using the NIMROD multi-detector at Texas A&M University. Thermal coalescence modes were employed to extract densities, $\rho$, and temperatures, $T$, for evolving systems formed in collisions

Magnetic Properties of Ferritin at Different Levels of Degradation: Implications for MRI‐Based Iron Quantification in the Brain

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2892-2897, May 2026.
ABSTRACT Purpose Ferritin's iron core exhibits complex magnetic properties, as suggested by magnetometry and Mössbauer spectroscopy, which remain incompletely understood. In particular, the antiferromagnetic inner core could influence the accuracy of iron quantification using MRI and raise concerns about postmortem validation studies involving degraded

Motion‐ and Field‐Robust Mesoscopic Whole‐Brain T2*$$ {T}_2^{\ast } $$‐Weighted Imaging at 7 and 11.7 T Using Servo Navigation

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2658-2670, May 2026.
ABSTRACT Purpose To mitigate artifacts related to motion and field changes in high‐resolution T2*$$ {T}_2^{\ast } $$‐weighted human brain imaging using servo navigation at ultra‐high fields up to 11.7 T. Methods MR‐based servo navigators were integrated into a segmented 3D‐EPI sequence to allow for prospective correction of involuntary head motion and ...

Brain Functional Connectivity as a Mediator Between Hematological Metrics and Cognitive Decline in Children With Beta‐thalassemia Major

Brain and Behavior, Volume 16, Issue 4, April 2026.
Connectome predictive modeling (CPM) revealed reduced functional connectivity linked to cognitive underperformance in children with β‐thalassemia major (β‐TM), which appeared to be modulated by multiple hematological factors. ABSTRACT Purpose This study aimed to identify functional brain connectivity patterns associated with cognitive performance in ...

Decay of instable Li, Be, and B fragments and the distortion of temperature measurements in heavy ion collisions [PDF]

, 2006
The recent attempts to extract the temperature in the late stage of medium energy (20–60 MeV/nucleon) heavy ion collisions from the yields of γ- and particle-instable fragments are discussed.
