Retinal nerve fibre layer thickness correlates with brain white matter damage in multiple sclerosis: a combined optical coherence tomography and diffusion tensor imaging study.

We investigated the association of retinal nerve fibre layer thickness (RNFL) with white matter damage assessed by diffusion tensor imaging (DTI). Forty-four MS patients and 30 healthy subjects underwent optical coherence tomography. DTI was analysed with a voxel-based whole brain and region-based analysis of optic radiation, corpus callosum and further white matter.

Functional and structural brain changes in anti-N-methyl-D-aspartate receptor encephalitis.

Objective: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune encephalitis with a characteristic neuropsychiatric syndrome and severe and prolonged clinical courses. In contrast, standard clinical magnetic resonance imaging (MRI) remains normal in the majority of patients. Here, we investigated structural and functional brain changes in a cohort of patients with anti-NMDAR encephalitis.

Angiotensin II type 2 receptor mediates sex differences in mice renal interlobar arteries response to angiotensin II.

Objective: Functional sex differences are described in several vascular beds. In the case of renal vessels, sex differences could influence processes like regulation of blood pressure and ion balance. Angiotensin II and nitric oxide are important regulators of renal vascular tone.

Dynamics of saccade parameters in multiple sclerosis patients with fatigue.

Fatigue is one of the most frequent and disabling symptoms in multiple sclerosis (MS). Its pathophysiology remains poorly understood and objective measures to quantify fatigue are unavailable to date. To investigate whether analysis of ocular motor movements can provide diagnostic information in MS patients with fatigue, 37 MS patients (21 female, age 44 ± 9 years) and 20 age- and gender-matched healthy controls were prospectively recruited.
