DOI: 10.1016/j.kint.2017.11.029
Abstract: Identifying subjects with progressive chronic kidney disease will be important both in clinical practice and in conducting clinical trials. Pruijm et al. (in this issue) demonstrate for the first time that cortical oxygenation as evaluated by… read more here.

DOI: 10.1016/j.rcl.2019.07.006
Abstract: Functional neuroimaging provides means to understand the relationship between brain structure and associated functions. Functional MR (fMR) imaging can offer a unique insight into preoperative planning for central nervous system (CNS) neoplasms by identifying areas… read more here.

DOI: 10.1089/brain.2017.0517
Abstract: Global signal regression is a controversial processing step for resting-state functional magnetic resonance imaging, partly because the source of the global blood oxygen level-dependent (BOLD) signal remains unclear. On the one hand, nuisance factors such… read more here.

DOI: 10.1089/brain.2018.0636
Abstract: Due to technological advances, spatially indexed objects, such as blood oxygen level-dependent time series or electroencephalography data, are commonly observed across different scientific disciplines. Such object data are typically high dimensional and therefore challenging to… read more here.

DOI: 10.1089/brain.2019.0677
Abstract: Both functional connectivity (FC) and blood oxygen level-dependent (BOLD) signal variability (SDBOLD) are methods to examine the physiological state of the brain. Although they are derived from signal changes and are related, few studies have… read more here.

DOI: 10.1097/rli.0000000000000871
Abstract: Objectives We propose a method of quantitatively measuring drug-induced microvascular volume changes, as well as drug-induced changes in blood oxygenation using calibrated blood oxygen level–dependent magnetic resonance imaging (MRI). We postulate that for MRI signals… read more here.

Free-field sound localization on the horizontal plane as a function of stimulus level with an electronic, level-dependent hearing protection device
Sign Up to like & getrecommendations! Published in 2017 at "Journal of the Acoustical Society of America"
DOI: 10.1121/1.4987835
Abstract: Electronic, level-dependent hearing protection devices (HPD) provide different levels of attenuation as a function of the input sound pressure level, so that loud sounds are attenuated for protection, but soft and moderate sound levels may… read more here.

DOI: 10.3174/ajnr.a5526
Abstract: BACKGROUND AND PURPOSE: Malignant glioma is a highly infiltrative malignancy that causes variable disruptions to the structure and function of the cerebrovasculature. While many of these structural disruptions have known correlative histopathologic alterations, the mechanisms… read more here.
