DOI: 10.1016/j.neuroscience.2017.02.033
Abstract: Some studies have demonstrated that aging is associated with impaired vestibular reflexes, especially otolithic reflexes, resulting in postural instability. However, the neurochemical basis of these age-related changes is still poorly understood. The l-arginine metabolic system… read more here.

DOI: 10.1148/radiol.2019181100
Abstract: Background Dual-energy (DE) CT allows reconstruction of virtual noncontrast (VNC) images from a single-phase contrast agent-enhanced examination, potentially reducing the need for multiphasic CT to characterize renal lesions. However, data regarding diagnostic performance of VNC… read more here.

DOI: 10.1177/02841851241271202
Abstract: Background Photon-counting computed tomography (PCCT) enables new ways of image reconstruction, e.g. material decomposition and creation of virtual non-contrast (VNC) series with higher resolution and lower radiation dose than standard computed tomography (CT). Clinical experiences… read more here.

DOI: 10.1534/genetics.119.301999
Abstract: The central nervous system of most animals is bilaterally symmetrical. Closer observation often reveals some functional or anatomical left–right asymmetries. In the nematode Caenorhabditis elegans, the most obvious asymmetry in the nervous system is found… read more here.
