BACKGROUND Esophageal cancer is one of the most aggressive malignancies in the world, and whether multiple therapeutic modalities could improve long-term survival remains controversial. Recent studies have shown an increase of cyclooxygenase-2 (COX-2) expression in various malignancies, but its clinicopathologic role in esophageal squamous cell carcinoma (ESCC) remains unclear. METHODS From 1...

non-steroidal anti-inflammatory drugs (nsaids), including selective cyclooxygenase (cox)-2 inhibitors, have come to play an important role in the pharmacologic management of musculoskeletal disorders. clinical trials have established the efficacy of etoricoxib in osteoarthritis, rheumatoid arthritis, acute gouty arthritis, ankylosing spondylitis, low back pain, acute postoperative pain, and pri...

It was determined that the studied 5-[(Z)-(4-nitrobenzylidene)]-2-(thiazol-2-ylimino)-4-thiazolidinone (Les-6222) affects cyclooxygenase pathway of arachidonic acid cascade, markers damage to neurons on models PTZ kindling. In model chronic epileptogenesis in mice (pentylenetetrazole kindling), a 4-thiazolidinone derivative showed high anticonvulsant activity, which is weaker than effect sodium...

The enzyme cyclooxygenase-2 (COX-2), responsible for the first committed step in the synthesis of several important mediators which are involved in both initiation and resolution of inflammation, and the subsequent generation of prostaglandins (PGs) upon activation has been shown to participate in the neurodegenerative processes of a variety of diseases. This review looks particular at the role...

arthritis refers to different medical conditions associated with disorder of the primary structures that determine joint functions such as bones, cartilage and synovial membranes. drug discovery and delivery to retard the degeneration of joint tissues are challenging. current treatments of different arthritis involves administration of ideal non-steroidal anti-inflammatory drugs (nsaids) but ar...

lation of a series of enzymes and signaling proteins in affected tissues and cells. Among the proinflammatory enzymes, the inducible forms of nitric oxide synthase (NOS) and cyclooxygenase (COX), which are responsible for increasing the levels of nitric oxide (NO) and prostaglandins (PGE2), are known to be involved in various chronic diseases including multiple sclerosis, Parkinson’s and Alzhei...

BACKGROUND AND PURPOSE Bacterial lipopolysaccharide (LPS), an endotoxin, has been reported to induce the expression of inducible isoforms of both nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) in various cell types. LPS is also known to dilate systemic vasculature, including cerebral vessels. This study aimed to determine to what extent LPS induces iNOS and COX-2 expression in the brai...

Non-Steroidal Anti-inflammatory drugs (NSAIDs), including selective cyclooxygenase (COX)-2 inhibitors, have come to play an important role in the pharmacologic management of musculoskeletal disorders. Clinical trials have established the efficacy of etoricoxib in Osteoarthritis, Rheumatoid Arthritis, Acute Gouty Arthritis, Ankylosing Spondylitis, Low back pain, acute postoperative pain, and pri...

This review summarizes our current understanding of the role of cyclo-oxygenase inhibitors (COXI) in influencing the structural development as well as the function of the developing kidney. COXI administered either during pregnancy or after birth can influence kidney development including nephronogenesis, and can decrease renal perfusion and ultrafiltration potentially leading to acute kidney i...
