The effect of prostaglandtn E(2), iloprost and cAMP on both nitric oxide and tumour necrosis factor-alpha release in J774 macrophages has been studied. Both prostaglandin E(2) and iloprost inhibited, in a concentration-dependent fashion, the lipopolysaccharide-induced generation of nitric oxide and tumour necrosis factor-alpha. The inhibitory effect of these prostanoids seems to be mediated by ...

OBJECTIVE To examine the relation between the serum levels of tumour necrosis factor alpha (TNFalpha), soluble tumour necrosis factor receptors (sTNF-R), and the histological pattern of rheumatoid synovitis. METHODS An enzyme linked immunosorbent assay (ELISA) was used to measure TNFalpha, p55 sTNF-R, and p75 sTNF-R concentrations in the serum of 43 patients with rheumatoid arthritis (RA) and...

Objective: To examine the relation between the serum levels of tumour necrosis factor α (TNFα), soluble tumour necrosis factor receptors (sTNF-R), and the histological pattern of rheumatoid synovitis. Methods: An enzyme linked immunosorbent assay (ELISA) was used to measure TNFα, p55 sTNF-R, and p75 sTNF-R concentrations in the serum of 43 patients with rheumatoid arthritis (RA) and 34 patients...

Human tumour cells are characterized by their ability to avoid the normal regulatory mechanisms of cell growth, division and death. The classical chemotherapy aims to kill tumour cells by causing DNA damage-induced apoptosis. However, as many tumour cells possess mutations in intracellular apoptosis-sensing molecules like p53, they are not capable of inducing apoptosis on their own and are ther...

AIMS Inflammatory and immune activation and body wasting are important features of end-stage chronic heart failure. It is not known whether restoration of cardiac output by assist device implantation can improve these abnormalities. METHODS We studied 48 patients (39 males; age 45+/-2 years) with NYHA class IV heart failure. All patients underwent ventricular assist device implantation for en...

Interleukin-1 beta, interleukin-2, tumour necrosis factor alpha, and the interferons, alfa and gamma, were measured concurrently in synovial fluid samples from 68 patients with rheumatic diseases. Mean interleukin-1 beta concentrations (130.3 (SD 22) pg/ml) were higher in synovial fluids from patients with rheumatoid arthritis (RA) than in those from patients with osteoarthritis (27.8(4.5)pg/ml...

1. Smoking exerts an inflammatory stimulus on lung macrophages, and smokers generally have low intakes of antioxidant micronutrients. This study was performed to investigate the relationship between whole-blood tumour necrosis factor production, plasma interleukin-6 and acute-phase protein concentration and antioxidant vitamins in smokers and non-smokers. 2. Measurement of tumour necrosis facto...

AIM To determine if a regimen with prandial + basal insulin compared with basal insulin attenuates post-meal inflammatory and glycative biomarkers in patients with Type 2 diabetes. METHODS This test-meal sub-study in the USA is from a previously reported clinical trial comparing the effect on glycaemic control of 24 weeks of thrice-daily pre-meal insulin lispro mix 50 (50% insulin lispro, 50%...

OBJECTIVE To investigate the serum levels of leptin, ghrelin and tumour necrosis factor-alpha in children with cyanotic and acyanotic congenital heart disease. METHODS The prospective cohort study, was conducted at imam Ali Hospital, Zahedan University of Medical Sciences, Iran, in 2009-10 and comprised 64 subjects, including patients and controls. Using enzyme-linked immunosorpent assay kits...
