OBJECTIVE Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine important in animal models of rheumatoid arthritis (RA). We investigated the utilization by MIF of mitogen activated protein (MAP) kinase signalling pathways in the stimulation of fibroblast-like synoviocytes (FLS), cyclooxygenase-2 (COX-2), prostaglandin E(2) (PGE(2)), and(More)
The glucocorticoid-induced antiinflammatory protein lipocortin 1 is present in arthritic synovium but its ability to regulate joint inflammation has not previously been studied. We investigated the role of lipocortin 1 in the antiinflammatory activity of glucocorticoids in an acute arthritis model induced by intraarticular injection of carrageenan. Compared(More)
OBJECTIVE Glucocorticoid-induced leucine zipper (GILZ) has effects on inflammatory pathways that suggest it to be a key inhibitory regulator of the immune system, and its expression is exquisitely sensitive to induction by glucocorticoids. We undertook this study to test our hypothesis that GILZ deficiency would exacerbate experimental immune-mediated(More)
Nitric oxide NO⋅ is a pro-inflammatory effector molecule in certain inflammatory diseases, including arthritis. We investigated the production of NO⋅ by adjuvant arthritis (AA) synovial macrophages, and studied the effects of a NO⋅ synthase inhibitor, N-iminoethyl-L-ornithine (L-NIO). Compared to control rats, rats treated with L-NIO in vivo exhibited(More)
To investigate whether Annexin 1 can protect a retinal ganglion cells line (RGC-5) from apoptosis as induced by serum deprivation. Annexin 1 location in RGC-5 cells was determined using an indirect immunofluorescent assay. Expression of Annexin 1 in RGC-5 cultures deprived of serum for 0, 2 days was semi-quantified by western blot and RT-PCR. Effects of(More)
Gastric precancerous diseases (GPD) may deteriorate into early gastric cancer if misdiagnosed, so it is important to help doctors recognize GPD accurately and quickly. In this paper, we realize the classification of 3-class GPD, namely, polyp, erosion, and ulcer using convolutional neural networks (CNN) with a concise model called the Gastric Precancerous(More)
