An oxidant/antioxidant imbalance in favour of oxidants has been identified as playing a decisive role in the pathogenesis of chronic inflammatory airway diseases. Nutritional antioxidant supplementation might reduce oxidative damage by enhancement of the antioxidant defence, thereby modulating
Gout is the most frequent cause of man's inflammatory arthritis after forty years of age and its prevalence is increasing. Although the physiopathology of this condition is starting to be thoroughly recognized, therapeutic approaches have not fundamentally changed during the last decades. In the
Various toxic or drug agents can induce arterial hypertension, aggravate or limit the efficiency of anti-hypertensive drugs. Iatrogenic and drug-induced hypertension should be well known by the clinicians and the pharmacists, given the impact for driving the management of patients. In the food, an
An 18-month-old Arabian-English filly resident in southwest France was referred for evaluation of a conjunctival mass in the right eye (OD). A pink, solid, and mobile nodular formation, measuring approximately 1.2 × 0.8 cm was found under the superior nasal bulbar conjunctiva during an ophthalmic
Advanced glycation end-products (AGE) are a group of heterogeneous molecules found in higher levels during diabetes, end stage renal failure and aging. Vascular alteration is correlated with their accumulation as during retinopathy or glomerulosclerosis. Glycation of extracellular matrix proteins is
The objective was to describe and model variation patterns in individual fish responses to contaminants among estuaries, season and gender. Two hundred twenty-seven adult European flounders were collected in two seasons (winter and summer) in four estuaries along the Bay of Biscay (South West
Ultrasound-guided ethanol injection (PEI) is an effective treatment of autonomously functioning thyroid nodules (AFTN) but little is known about the tissue lesions induced by alcohol. We report morphological changes of an AFTN which was removed after successful PEI treatment. At histological
BACKGROUND
The role of oxidative stress in the formation of aneurysms is not fully understood. We used the complementary DNA (cDNA) microarray technique to determine the transcription profile in the development of elastase-induced abdominal aortic aneurysm in rat models, with an emphasis on the
Iron metabolism in mammals requires a complex and tightly regulated molecular network. The classical view of iron metabolism has been challenged over the past ten years by the discovery of several new proteins, mostly Fe (II) iron transporters, enzymes with ferro-oxydase (hephaestin or
Acute headaches are in most cases significant symptoms or premonitary signs of a neurological condition. From a semiological point of view, they may be: (i) isolated, (ii) associated with neurological symptoms (ophtalmoplegia, hemiplegia, hemianesthesia...). From an etiological point of view, the
IL-1 and TNF-alpha are potent inducers of matrix metalloproteinases (MMP), eicosanoids, nitric oxide oxydase (iNOS), receptor activator of NF-kB ligand (RANKL), products involved in the destruction of the extracellular matrix, the cartilage and in bone resorption. IL-1, particularly important at the
Interleukin-1 (IL-1) and tumor necrosis factor (TNFalpha) are key mediators of inflammation and are produced by monocyte-macrophages (Mphi) following the activation of soluble factors and contact with stimulated Th1 lymphocytes. The contact between lymphocytes and Mphi is regulated by ligand and
BACKGROUND
An increasing number of studies suggest that chlamydiae can infect immune cells. The altered immune cell function could contribute to the progression of several chronic inflammatory diseases.The aim of this study was to comparatively evaluate Chlamydia pneumoniae (CP) and Chlamydia
The present review describes the role of the putative cross-talk between two neurotransmitters, nitric oxide (NO) and D-serine, in the brain. Under physiological conditions NO homeostasis guarantees the correct function of NO in a number of events in the brain such as neurotransmission and vascular
Gout is not a new disease for clinicians; nevertheless, there are still many secrets awaiting discovery for improving knowledge with respect to uric acid metabolism and monosodium urate crystal-induced inflammation. This review of the literature will focus on new insights on the pathogenesis of
