Identification of Novel Protein Biomarkers for Myasthenia Gravis by Integrating Human Proteomics with Genetic Instruments.

Myasthenia gravis (MG) presents significant health and economic challenges. To identify novel biomarkers, we analyzed proteomic data from 52,704 UK Biobank individuals, focusing on 1463 baseline proteins with follow-up >10 years. Baseline and potential MG cases were 1:5 matched to controls by using propensity score matching.

Impact of body mass index on clinical presentation and prognosis in myasthenia gravis.

Background: The literature lacks consistent information on the correlation between baseline body mass index (BMI), clinical presentation, and prognosis in patients with myasthenia gravis (MG). This observational multicenter prospective cohort study included patients with MG from February 2017 to June 2023, categorizing them by baseline BMI. The primary outcome was the time to generalization of ocular MG.

Brain structural and functional connectivity alterations are associated with fatigue in neuromyelitis optica spectrum disorder.

Background: Many patients with neurological disorders experience chronic fatigue, but the neural mechanisms involved are unclear.

Objective: Here we investigated whether the brain structural and functional connectivity alterations were involved in fatigue related to neuromyelitis optica spectrum disorder (NMOSD).

Methods: This prospective pilot study used structural and resting-state functional brain magnetic resonance imaging to compare total cortical thickness, cortical surface area, deep gray matter volume and functional connectivity (FC) between 33 patients with NMOSD and 20 healthy controls (HCs).

Association of polymorphisms with neuromyelitis optica spectrum disorders in Han Chinese patients.

Variants at the GTF2I repeat domain containing 1 (GTF2IRD1)-GTF2I locus are associated with primary Sjögren's syndrome, systemic lupus erythematosus, and rheumatoid arthritis. Numerous studies have indicated that this susceptibility locus is shared by multiple autoimmune diseases. However, until now there were no studies of the correlation between GTF2IRD1-GTF2I polymorphisms and neuromyelitis optica spectrum disorders (NMOSD).

[Anxiety and Depression in Patients with Neuromyelitis Optica].

Objective: To assess anxiety and depression in patients with neuromyelitis optica (NMO).

Methods: Eligible patients with NMO were assessed with Hamilton anxiety rating scale-14 (HARS-14),Hamilton depression rating scale-21 (HDRS-21) and expanded disability status scale (EDSS).

Results: A total of 65 NMO patients [(39.

Muscle damage in patients with neuromyelitis optica spectrum disorder.

Objective: Increasing evidence has shown that skeletal muscle damage plays a role in neuromyelitis optica spectrum disorder (NMOSD). The objective of this study was to compare the serum creatine kinase (sCK) levels in NMOSD patients with different clinical statuses.

Methods: In the observational study, levels of sCK were measured during the acute and stable phases for patients with NMOSD and healthy controls (HCs).

[Correlates of Fatigue in Patients with Neuromyelitis Optica].

Objectives: To determine clinical characteristics associated with fatigue in patients with neuromyelitis optica (NMO).

Methods: A questionnaire survey was conducted in NMO patients, measuring fatigue using the fatigue impact scale (FIS).

Results: A total of 64 NMO patients (mean age: 50.

Outbreak of Avian Tuberculosis in Commercial Domestic Pekin Ducks ( Anas platyrhynchos domestica).

Avian tuberculosis is a contagious disease affecting various domestic and wild bird species, and is caused by Mycobacterium avium . It is reported extremely rarely in commercial poultry flocks and has not been reported in commercial domestic ducks to date, with domestic ducks reported to be moderately resistant to M. avium infection.

Complete Genome Sequence of Mycobacterium avium, Isolated from Commercial Domestic Pekin Ducks (Anas platyrhynchos domestica), Determined Using PacBio Single-Molecule Real-Time Technology.

Mycobacterium avium is an important pathogenic bacterium in birds and has never, to our knowledge, reported to be isolated from domestic ducks. We present here the complete genome sequence of a virulent strain of Mycobacterium avium, isolated from domestic Pekin ducks for the first time, which was determined by PacBio single-molecule real-time technology.

Differential expression of IQGAP1/2 in Hepatocellular carcinoma and its relationship with clinical outcomes.

Purpose: To investigate IQGAP1 and IQGAP2 expression in hepatocellular carcinoma (HCC) and itsassociation with HCC clinicopathological characteristics and survival outcomes.

Methods: IQGAP1 and IQGAP2 mRNA and protein were measured in HCC tissues, para-tumor tissues and normal tissues by RT-PCR and Western blotting. We further examined 150 HCC samples with adjacent para-tumor tissues and 11 normal specimens by immunohistochemistry to evaluate the correlation of IQGAP1 and IQGAP2 with clinicopathological features and prognosis.
