We report the case of a 40 year-old man with multiple sclerosis, who presented a bilateral proliferative retinopathy responsible for a vitreous hemorrhage. Examination of the periphery of the retina showed diffuse retinal periphlebitis; fluorescein angiograms showed a peripheral retinal ischemic syndrome with secondary neovascularization. Several recent studies have show that retinal periphlebitis is a frequent finding in multiple sclerosis; but to our knowledge a retinal ischemic syndrome with neovascularization has seldom been reported.

Challenges in the Diagnosis and Management of Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD).

Myelin oligodendrocyte glycoprotein antibody-associated disease has been recently identified to be a distinct autoimmune central nervous system disorder. There is significant clinical and radiological overlap with multiple sclerosis and aquaporin-4-IgG-associated neuromyelitis optica spectrum disorders. Clinical course is variable in that patients may have a monophasic or relapsing course, disease severity is unpredictable, and unlike other idiopathic autoimmune inflammatory disorders, there is no gender predilection and it is more likely to affect pediatric population.

Neurodegenerative disorders are characterized by a progressive loss of neurons, causing substantial deficits in motor and cognitive functioning. Bilirubin is a yellow by-product of heme, existing in two primary isoforms namely unconjugated and conjugated, while initially produced unconjugated isomer is lipophilic and cytotoxic in nature. At physiological levels, bilirubin has an important role in brain function by acting as a powerful antioxidant, preventing brain tissues from oxidative damage by eliminating reactive oxygen species (ROS).

Multiple sclerosis (MS) is a prevalent inflammatory neurodegenerative disease in young people, causing neurological abnormalities and impairment. To investigate a novel therapeutic agent for MS, we observed the impact of maresin 1 (MaR1) on disease progression in a well-known, relapsing-remitting experimental autoimmune encephalomyelitis (RR-EAE) mouse model. Treatment with MaR1 accelerated inflammation resolution, reduced neurological impairment, and delayed disease development by reducing immune cell infiltration (CD4+IL-17+ and CD4+IFNγ+) into the central nervous system (CNS).

Objectives: To assess topographical patterns of metabolic abnormalities in the cerebrum of multiple sclerosis (MS) patients and their relationship to clinical disability using rapid echo-less 3D-MR spectroscopic imaging (MRSI) at 7T.
Materials And Methods: This study included 26 MS patients (13 women; median age 34) and 13 age- and sex-matched healthy controls (7 women; median age 33). Metabolic maps were obtained using echo-less 3D-MRSI at 7T with a 64 × 64 × 33 matrix and a nominal voxel size of 3.
Novel tertiary diarylethylamines as functionally selective agonists of the kappa opioid receptor.

Novel kappa opioid receptor (KOR) agonists that preferentially activate G-protein signaling versus β-arrestin-2 recruitment are described. Starting from a literature-reported phenol-containing diphenethylamine KOR agonist, structure-activity relationship (SAR) studies revealed replacement of the phenol with various non-hydroxylated bicyclic heteroaromatics led to tertiary diarylethylamines which retained KOR agonist activity and improved metabolic stability in human liver microsomes. Further optimizations produced compound 39, a potent activator of G-protein signaling (GTPγS EC = 14 nM, 83 % E) that did not elicit a β-arrestin-2 recruitment functional response (E < 10 %).
