Production de styrene par Penicillium camemberti Thom

1989

National audience; The Celluloïd taste observed in some mould-ripened cheeses is bound to the presence of styrene in these cheeses. The accumulation of this molecule was only detected on cultures of some strains of Penicillium camemberti. It seems to be bound to a deregulation of oxidative metabolism of tneee strains.; L'apparition du goût de Celluloïd dans les fromages à pâte molle à croûte fleurie est liée à la présence de styrène dans ces fromages. L'accumulation de cette molécule n'est observée que sur des cultures de souches particulières de Penicillium camemberti. Elle semble liée à un dérèglement du métabolisme oxydatif de ces souches.

Allopurinol Protective Effect of Renal Ischemia by Downregulating TNF-α, IL-1β, and IL-6 Response

2016

Allopurinol is a well-known antioxidant that protects tissue against ischemia and reperfusion injury, blocking purine catabolism, and possibly reducing TNF-α and other cytokines. It also plays a significant role in reducing the inflammatory processes by inhibiting chemotaxis and other inflammatory mediators. The objective of this study was to define the role of allopurinol regarding kidney ischemic injury particularly as to its effect on inflammatory molecules such as TNF-α, IL-1β, and IL-6 response. One hundred and twenty five rats were subjected to warm renal ischemia. Five more animals were included as sham. Animal survival and plasma levels of lipid peroxidation, myeloperoxidase, lactat…

Anti-hyperuricemic and nephroprotective effects of extracts from Chaenomeles sinensis (Thouin) Koehne in hyperuricemic mice

2018

Clinically, Chaenomeles sinensis (Thouin) Koehne (C. sinensis) has been used to treat hyperuricemia and gout. However, the exact mechanism of action is still unknown. In the present study, the ethyl acetate fraction of C. sinensis fruit extract (CSF-E) was separated. Potassium oxonate (PO)-induced hyperuricemic mice and normal mice were administered with CSF-E at 60, 120 and 180 mg kg-1, respectively for 7 days. Serum uric acid, creatinine and BUN levels, liver oxidative damage, and serum and hepatic XOD activities were primarily measured using assay kits. The evaluation of its nephroprotective effects was carried out by renal histopathological analysis. Simultaneously, renal protein levels…

Significant divergences between the temporal structure of the behavior in Wistar and in the spontaneously more anxious DA/Han strain of rats tested i…

2013

Abstract The aim of present research is to study the temporal structure of the behavior in two strains of rats with different basal level of emotionality. To this purpose, the temporal profile of the behavior in Wistar rat and in the spontaneously more anxious DA/Han strain was analyzed in the Elevated Plus Maze. Both quantitative and multivariate t-pattern analyses were carried out. In comparison with Wistar, DA/Han subjects showed a significant reduction of the permanence in open arm and a significant increase of the time spent in the central platform of the maze. Mean frequencies of each behavioral element showed significant modifications both in open and in closed arm. Multivariate t-pa…

Gout, allopurinol intake and clinical outcomes in the hospitalized multimorbid elderly.

2014

Background: Increased serum uric acid has been considered a cardiovascular risk factor but no study has assessed its relation with hospital mortality or length of stay. On the basis of data obtained from a prospective registry, the prevalence of gout/hyperuricemia and its association with these and other clinical parameters was evaluated in an Italian cohort of elderly patients acutely admitted to internal medicine or geriatric wards. Methods: While the prevalence of gout was calculated by counting patients with this diagnosis hyperuricemia was inferred in patients taking allopurinol at hospital admission or discharge, on the assumption that this drug was only prescribed owing to the findin…

A case of naturally evolving gout in an elderly man

2012

Gout is a common disorder in adults that can lead to severe organ decline, disability and impaired quality of life due to the formation of periarticular tophi. We report a case of massive tophaceous gout in a 78-year-old man with a 16-year-long history of untreated disease. The patient gradually became disabled, his renal function deteriorated, and he finally died of sepsis. Our case demonstrates that chronic gout not only affects the joints, but is also associated with organ function decline and can, even nowadays, lead to death. © 2011 Elsevier Ireland Ltd.

Different Surgical Approaches to Treat Chronic Tophaceous Gout in the Hand: Our Experience

2010

Chronic tophaceous gout is a disabling erosive arthritis characterized by an elevated serum urate concentration, recurrent attacks of arthritis, and deposits of monosodium urate crystals in synovial fluids. Tophi, ulcerations of the overlying skin, and fissures of the interarticular cartilage may occur in advanced stages, combined with deformities of the joints and decreased active joint flexion and extension. Although the timely use of allopurinol is associated with a decrease in the frequency of deposits of the tophaceous substance, however, surgical management is necessary to restore and improve the cosmesis and joint function, to alleviate symptomatic discomfort, and to reduce the risk …

Tophaceous gout in the elderly: A clinical case review

2012

Gout is the most common cause of arthritis in the elderly. Its incidence among older people has risen worldwide due to an increase in risk factors such as renal diseases, metabolic syndrome, and a diet rich in purines. In older age, tophaceous gout may affect different joints from its classical presentation, due to other concomitant musculoskeletal diseases, but specific data on its epidemiology and clinical aspects in the elderly are limited to a few case reports. The present review focuses on the distinctive aspects of tophaceous gout in the elderly, revisiting all our clinical cases seen from 1990 to December 2011. Our findings indicate that: tophaceous gout can affect several joints in …

Case Report: The JAK-Inhibitor Ruxolitinib Use in Aicardi-Goutieres Syndrome Due to ADAR1 Mutation

2021

Type I Interferonopathies comprise inherited inflammatory diseases associated with perturbation of the type I IFN response. Use of Janus kinase (JAK) inhibitors has been recently reported as possible tools for treating some of those rare diseases. We describe herein the clinical picture and treatment response to the JAK-inhibitor ruxolitinib in a 5-year-old girl affected by Aicardi-Goutières Syndrome type 6 (AGS6) due to ADAR1 mutation. The girl's interferon score (IS) was compared with that of her older brother, suffering from the same disorder, who was not treated. We observed a limited, but distinct neurological improvement (Gross Motor Function and Griffiths Mental Development Scales). …
