Sensitivity and specificity of Interleukin 29 in patients with rheumatoid arthritis and other rheumatic diseases.

Sensitivity and specificity of Interleukin 29 in patients with rheumatoid arthritis and other rheumatic diseases. Immunol Lett. 2020 Jan 16;: Authors: da Rocha Junior LF, Angela Luzia Branco PD, de Melo Rêgo MJB, de Almeida AR, de Melo Vilar K, de Lima HD, Andréa Tavares D, de Ataíde Mariz H, da Rocha Pitta I, da Rocha Pitta MG Abstract BACKGROUND: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic and progressive inflammation that can cause a high degree of disability in affected individuals. Proinflammatory cytokines play central roles in the development of degradative and inflammatory responses in RA. IL-29 has been identified in RA and reported as a biomarker of the disease. OBJECTIVE: To analyze serum levels and accuracy of IL-29 in RA patients compared to healthy subjects and patients with other rheumatic diseases. METHODS: IL-29 serum levels were measured in 121 patients with RA, 53 patients with systemic lupus erythematosus (SLE), 60 patients with systemic sclerosis (SSc), 29 patients with fibromyalgia (FM), 50 patients with osteoarthritis (OA) and 68 healthy individuals as controls. IL-29 levels in serum were investigated by ELISA. Sensitivity, specificity and likelihood ratios (LR) for having RA were calculated. RESULTS: Serum levels of IL-29 were increased in RA patients 113.6 (IQR = 31.25-308.5) pg/ml compared to non-RA patients (SLE, SSc, OA, and FM) (31.25&thi...

Some epileptic spasms are classified into focal-onset seizures. However, the cortical network underlying this kind of spasm seizure is not yet clear. Four patients with epileptic spasms who underwent intracranial electrode implantation and focal resection surgery were studied. All the patients had good outcomes, and three of them with intellectual disability showed improved intelligence after surgery. The power spectra characteristics of electrocorticography and the dynamic functional network changes of epileptic spasms were investigated. Electrocorticography power in the resected zone peaked 0.5 seconds before the clinica...

In this study, the sibling relationship attitudes of adult siblings of people with (N = 133) and without (N = 140) intellectual and developmental disabilities were explored. Feelings, behaviors, and thoughts related to sibling relationships were measured using the Lifespan Sibling Relationship Scale; depression was measured using the Beck Depression Inventory-II; anxiety was measured using the Beck Anxiety Inventory; and life satisfaction was measured using the Satisfaction With Life Scale. Results indicate that higher levels of positive sibling relationship attitudes are negatively related to levels of depression and anxi...

In this study, we utilize the frog, Xenopus laevis as a simpler and more accessible vertebrate neurodevelopmental model system to understand the embryological cause of Bainbridge-Ropers syndrome. We have found that ASXL3 protein knockdown during early embryo development highly perturbs neural cell fate specification, potentially resembling the Bainbridge-Ropers syndrome phenotype in humans. Thus, the frog embryo is a powerful tool for understanding the etiology of Bainbridge-Ropers syndrome in humans.

We examined the pain-reducing, anti-inflammatory, and chondroprotective effects of wogonin when applied as a topical cream. We validated the efficacy of delivering wogonin transdermally in a cream using pig ear skin in a Franz diffusion system. Using a surgical mouse model, we examined the severity and progression of OA with and without the topical application of wogonin. Using a running wheel to track activity, we found that mice with wogonin treatment were statistically more active than mice receiving vehicle treatment. OA progression was analyzed using modified Mankin and OARSI scoring and direct quantification of cyst-...

This is the latest in a series of yearly posts in which I suggest areas of development for biotech startups I'd like to see actively developed as a part of the longevity industry in the near future. Today, this year, is a good time to be starting a company focused on the production of a novel therapeutic approach to intervening in the aging process. There is a great deal of funding for seed stage investment, and many compelling projects lacking champions, yet to be carried forward from academia into preclinical development. Numerous scientific and industry crossover conferences are now held every year, at which it is possi...
