Psychrophilic enzymes produced by cold-adapted microorganisms display a high catalytic efficiency and are most often, if not always, associated with high thermosensitivity. Using X-ray crystallography, these properties are beginning to become understood, and the rules governing their adaptation to cold appear to be relatively diverse. The application of these enzymes offers considerable potential to the biotechnology industry, for example, in the detergent and food industries, for the production of fine chemicals and in bioremediation processes.

The case of a 56-years-old male with cholestasis associated with ticlopidine is presented. Cholestasis is an infrequent adverse effect of this drug. The patient was admitted to hospital because of jaundice, choluria, and itching of one month of evolution. The patient had taken ticlopidine twice a day for 3 months up to one week prior to admission for peripheral arteriopathy. Biopsy was performed showing acinar cholestasis and portal inflammatory infiltrate compatible with cholestasis due to hypersensitivity. Ticlopidine was discontinued by the patient himself one week prior to admission. The drug was not readministered and the evolution of the clinical and biochemical parameters of cholestasis decreased. The patient was asymptomatic and laboratory data were normal 4 months later. [less ▲]

The avian pathogenic E. coli strains, although considered by almost like opportunist pathogen, represent actually one of the most important cause of economic losses in the poultry sector and is one of the most frequent cause of carcase rejection in the slaughter house. Colibacillosis, which the major way of penetration is the respiratory tract, affect essentially broilers and give variable lesions and manifestations in function of the age of the animals. Actually, some virulence factors have been studied and associated with avian pathogenic E. coli strains : P and F1 fimbriae, hemagglutination, serum resistance, aerobactin system. Recent studies have also showed that other virulence factors (F17 and Afa adhesins) were also present in the avian pathogenic E. coli, but their rule in the pathogenicity must to be established. Because of the diversity of virulence factors and the little of knowledge about us, no vaccine is actually available to protect efficacely poultries against colibacillosis. Thus, the antibiotherapy based on a good diagnostic and a good prevention remained the only things to do in order to overcome the disease, despite the augmentation of antibiotics resistance and the risk of transferring to humans.

We report the case of a 52 year old man who was hospitalized within a context of a persistent deterioration of his general condition. He was suspected of having a chronic inflammatory colitis. A pulmonary radiography revealed the presence of voluminous bilateral excavated masses with hydro-aerical levels. After having refuted among others a suspicion of tuberculosis, the results of a thoracic percutaneous transpleural lung aspiration by needle under tomodensitometric control steered our diagnosis towards a vascularitis of the Wegener disease type. A treatment with corticotherapy in large doses completed with cyclophosphamid allowed for clinical, biological and radiological improvement. Wegener's granulomatosis usually starts in an insidious manner with febrile episodes and an impairment of the general condition associated with inflammatory biological signs, as observed in our patient. After these warning symptoms, come ORL and/or pulmonary and/or renal impairment, which represent the classical triad of diffused GW. However a certain number of particularities unusual for that diagnosis characterized our patient and prompted the discussion of this case. [less ▲]

The measurement of biomarkers that reflect cartilage breakdown is a powerful tool for investigating joint damage caused by disease or injury. Particularly in cases of osteochondrosis, synovial concentrations of these biomarkers may reveal the presence of osteoarthritic changes. Coll2-1, Coll2-1 NO2 and myeloperoxidase have recently been introduced in equine osteoarticular research but comparison between the concentrations of these markers in OCD affected and healthy joints has not been made. Therefore, this study aimed at reporting the synovial concentrations of these biomarkers in joints affected with osteochondral fragments in the tarsocrural joint compared to unaffected joints. Myeloperoxidase and Coll2-1NO2 revealed to have similar levels between affected joints and controls. However, in contrast to previous studies using C2C the present study demonstrated that synovial levels of Coll2-1 were significantly elevated in tarsocrural joints affected with osteochondrosis. Thus, Coll2-1 may be an earlier marker of cartilage degeneration than other cartilage degradation markers that have been previously used in equine medicine. [less ▲]

OBJECTIVE: Erosive osteoarthritis of the hand (EHOA) is thought to be an aggressive variant of hand osteoarthritis (HOA) characterised by prominent local inflammation and radiographic aspects of bone erosions in interphalangeal (IP) joints. However, rare studies have until now investigated the value of biomarkers in these patients. Thus, we determined Coll2-1, a marker of type II collagen denaturation, its nitrated form (Coll2-1NO2) and myeloperoxidase (MPO) levels in serum of patients with EHOA vs non-EHOA and subsequently evaluated their relationships with disease indices of severity and activity. METHODS: Coll2-1, Coll2-1NO2 and MPO were measured using specific immunoassays in 82 patients, 57 with EHOA, all females, median age 59 (41-74 yrs) and 20 with non-EHOA, all females, median age 55 (43-73 yrs), fulfilling the American College of Rheumatology (ACR) criteria for hand OA. EHOA was characterized by the presence of at least one central bone erosion on radiograph in the IP joints. Patients were also evaluated for disease duration, number of affected (swollen and painful or tender) joints, radiographic score (RS) by Kallman scale and high sensitivity C-reactive protein (hsCRP). RESULTS: Serum levels of MPO were higher in EHOA (230.0 +/- 152.1 ng/ml) than in non-EHOA (160.2 +/- 111.5 ng/ml, P=0.037). Coll2-1NO2 levels trended towards an elevation in EHOA compared non-EHOA (0.40 +/- 0.86 vs 0.22 +/- 0.14 nmol/l, P=0.06), while Coll2-1 levels were not different. Correlations were found for disease duration and both MPO (R(2)=0.48, P=0.001) and Coll2-1NO2 (R(2)=0.73, P=0.01) after the splitting of the population in subgroups according to a cut off value above the 50th percentile. A correlation was found between hsCRP and MPO (R(2)=0.57, P=0.01). CONCLUSIONS: This study clearly demonstrates an elevation of some serum biomarkers in EHOA, in comparison with non-EHOA. In particular, MPO, hsCRP and the ratio Coll2-1NO2/Coll2-1 discriminated the two subsets of hand osteoarthritis (HOA), and a trend was also observed for Coll2-1NO2. These data suggest that these biomarkers could be helpful for the diagnosis of EHOA. [less ▲]
