Clinical, prognostic and pathophysiological implications of MOG-IgG detection in the CSF: the importance of intrathecal MOG-IgG synthesis.

Background: Cerebrospinal fluid myelin oligodendrocyte glycoprotein IgG (CSF MOG-IgG) are found in a proportion of patients with MOG antibody-associated disorder (MOGAD) and have been associated with severe disease presentations. However, most studies did not systematically investigate the role of MOG-IgG intrathecal synthesis (ITS).

Methods: We retrospectively studied 960 consecutive patients with paired serum and CSF samples screened for MOG-IgG using a live cell-based assays.

Epeleuton, a novel synthetic ω-3 fatty acid, reduces hypoxia/ reperfusion stress in a mouse model of sickle cell disease.

Inflammatory vasculopathy is critical in sickle cell disease (SCD)-associated organ damage. An imbalance between pro-inflammatory and pro-resolving mechanisms in response to different triggers such as hypoxia/reoxygenation or infections has been proposed to contribute to the progression of SCD. Administration of specialized pro-resolving lipid mediators may provide an effective therapeutic strategy to target inflammatory vasculopathy and to modulate inflammatory response.

Cobblestone-like brain malformation with a new bi-allelic ADGRG1 (GPR-56) mutation: Fetal imaging-pathology correlation.

Background And Purpose: Autosomal recessive cobblestone-like cortical malformation of the brain, with no eye or muscle involvement, has been reported in patients with biallelic mutations in ADGRG1 (formerly GPR56) and in other brain surface defects (eg, variants in COL3A1). We reported the intra-uterine brain MRI (iu-MRI), post-mortem MRI (pm-MRI), and neuropathology findings of a new ADGRG1 mutation in a fetus at early gestation. Imaging findings were compared with those of the sibling harboring the same mutation, to provide insights about the evolving morphology of such malformation.

A facile and fully automated on-fiber derivatization protocol for direct analysis of short-chain aliphatic amines using a matrix compatible solid-phase microextraction coating.

Solid-phase microextraction (SPME) analysis of short-chain aliphatic amines (C3-C6) in aqueous solutions was investigated using pentafluorobenzaldehyde (PFBAY) as on-fiber derivatization reagent. A standard gas generating vial agent was used for on-fiber loading of the derivatization agent so as to avoid the need for its regeneration at each derivatization cycle. Several parameters such as loading time, reaction temperature, and reaction/extraction time were optimized for headspace and direct sampling in aqueous solutions.

Clinical problems and everyday abilities of a group of Italian adolescent and young adults with Cornelia de Lange syndrome.

Cornelia de Lange syndrome (CdLS) is a multiple congenital anomaly/mental retardation syndrome, characterized by distinctive facial features, generalized hirsutism, growth and cognitive dysfunction, microcephaly and limb abnormalities. Currently mutations of three different genes, NIPBL, SMC1A, and SMC3, are known to be related to the CdLS phenotype with an overall detection rate of about 50%. Few data are available regarding the level of autonomy in everyday life of CdLS patients.

Analysis of congenital heart defects in 87 consecutive patients with Brachmann-de Lange syndrome.

Congenital heart defects (CHDs) have been estimated to occur in approximately 20% of patients with Brachmann-de Lange syndrome (BDLS, also known as Cornelia de Lange syndrome, OMIM 122470). We report on the results of a prospective echocardiographic evaluation of a cohort of 87 Italian BDLS patients with longitudinal follow-up from 5 to 12 years. A cardiac anomaly was identified in 29/87 (33.
