A BOLD search for baseline [PDF]

open access: yesNeuroImage, 2007
While we occasionally observe negative BOLD signals, its physiological basis has remained uncertain. This is in part due to the qualitative use of fMRI where the baseline is conveniently differenced away to reveal focal area(s) of interest. Recently, however, there has been a noticeable trend towards quantitative neuroimaging where changes in oxidative

BOLD-signal after sumatriptan administration: Group BOLD-fMRI results for noxious stimulation to the V1 area on the placebo day.

open access: yes, 2016
Here differences in neuronal activation between the BOLD-fMRI scan at T-5 (baseline) and T60 (after sumatriptan) is shown. Sumatriptan injection resulted in positive activation of the supplementary motor area (sup.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

open access: yesMolecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Zebrafish (Danio rerio) behavioral phenotypes are not underscored by different gut microbiomes

open access: yesEcology and Evolution
Although bold and shy behavioral phenotypes in zebrafish (Danio rerio) have been selectively bred and maintained over multiple generations, it is unclear if they are underscored by different gut microbiota.

Modeling the impact of neurovascular coupling impairments on BOLD-based functional connectivity at rest

open access: yesNeuroImage, 2020
Functional magnetic resonance imaging (fMRI) of blood oxygenation level dependent (BOLD) signals during the resting-state is widely used to study functional connectivity (FC) of slowly fluctuating ongoing brain activity (BOLD-FC) in humans with and ...

From Blood Oxygenation Level Dependent (BOLD) signals to brain temperature maps [PDF]

open access: yes, 2010
A theoretical framework is presented for converting Blood Oxygenation Level Dependent (BOLD) images to temperature maps, based on the idea that disproportional local changes in cerebral blood flow (CBF) as compared with cerebral metabolic rate of oxygen ...

Continuous EEG source imaging enhances analysis of EEG-fMRI in focal epilepsy [PDF]

open access: yes, 2010
Introduction: EEG-correlated fMRI (EEG-fMRI) studies can reveal haemodynamic changes associated with Interictal Epileptic Discharges (IED). Methodological improvements are needed to increase sensitivity and specificity for localising the epileptogenic ...

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

open access: yesMolecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...

Faculty Performance Evaluation through Multi-Criteria Decision Analysis Using Interval-Valued Fermatean Neutrosophic Sets

open access: yesMathematics, 2023
The Neutrosophic Set (Nset) represents the uncertainty in data with fuzzy attributes beyond true and false values independently. The problem arises when the summation of true (Tr), false (Fa), and indeterminacy In values crosses the membership value of ...
