Attaching and effacing Escherichia coli is a new causal agent of diarrhea in calves. Its major virulence factors are the intimin protein, encoded by the eaeA gene, and the Shiga-like toxins, encoded by slt genes. Because the sequences of these genes are available, we selected specific primers to amplify each virulence gene so as to develop a new identification test based on multiplex amplification of virulence-associated genes. Of 30 tested strains, 14 were eaeA+, 15 were eaeA+ slt-I+, 1 was eaeA+ slt-I+ slt-II+, and 1 was eaeA+ slt-II+. The method proved in our hands to be fast and specific and in perfect correlation with the hybridization method. [less ▲]

During the last decade, research in exercising horses provided growing evidence that the respiratory system may be a limiting factor for maximal performance, even in healthy animals. Therefore, any pulmonary dysfunction, even subclinical or moderate, may significantly impair the aerobic metabolism and consequently performance of exercising horses. This paper briefly presents the main respiratory troubles of lower airway as well as the main pulmonary function tests used to diagnose these diseases. [less ▲]

The TM2 atmospheric transport model, a parameterization of soil heterotrophic respiration and a mechanistic model of carbon assimilation in the biosphere (CARAIB) are combined to estimate the net primary productivity of the continental vegetation. The model includes the determination of the leaf area index (LAI) of the various vegetation covers, the CO2 assimilation by the leaves, and the respiration of standing biomass. It also includes a soil hydrological model forced with monthly mean air temperature, precipitation and solar radiation fields and using a stochastic generation of daily weather within each month. It is shown that the seasonal fluctuations observed at various monitoring stations can be well reproduced, thus validating the mechanistic approach adopted to calculate the global net primary productivity. A Fourier analysis of the modelled atmospheric signal is performed to quantify the relative importance of the vegetation in the different latitude zones and the contribution of the various vegetation types. In the southern hemisphere, the calculated phase and amplitude of the CO2 signal are not so well reproduced since atmosphere-ocean exchanges should also be considered in addition to the biospheric source. The latest updates and simulations performed with the model will be presented and discussed. [less ▲]

Immunosuppressed patients are susceptible to complicated diverticulitis, but reports of this complication are scarce in heart graft recipients. To estimate the prevalence of acute diverticulitis in heart graft recipients, we retrospectively reviewed the cases of diverticulitis in a series of 143 patients who underwent orthotopic heart transplantation in a period of 10 years. Six (4%) of these developed acute diverticulitis and required colectomy. All of them were male patients and were older than 50 years. Four patients underwent urgent laparotomy and colon resection with end colostomy (Hartmann procedure). The two other patients suffered from diverticulitis without generalized peritonitis and underwent laparoscopic sigmoidectomy with direct transanal end-to-end anastomosis. The postoperative outcomes of these six patients were satisfactory. As are other immunosuppressed patients, heart graft recipients are susceptible to diverticulitis. Early surgical management may be safe in well-compensated patients. [less ▲]

We studied the inflammatory reaction related to cardiopulmonary bypass in 24 neonates (median age 6 days) undergoing the arterial switch operation for simple transposition of the great arteries, with respect to the development of postoperative capillary leak syndrome. Complement proteins, leukocyte count, tumor necrosis factor-α, and histamine levels were determined before, during, and after cardiopulmonary bypass. Additionally, protein movement from the intravascular into the extravascular space during cardiopulmonary bypass was assessed by the measurement of plasma concentrations of proteins with molecular weights ranging from 21,200 to 718,000. Capillary leak syndrome developed in 13 of the 24 neonates. Patients with capillary leak syndrome, as compared with those without, had preoperatively higher C5a levels (C5a, 3.0 ± 0.6 μg/L vs 0.9 ± 0.2 μg/L) (mean ± standard error of the mean) (p < 0.05) and higher leukocyte counts (leukocytes, 17.9 ± 2.1 x 10 3 cells/ml versus 11.7 ± 0.8 x 10 3 cells/ml) (p < 0.05), suggesting in these neonates a preoperative inflammatory state. Preoperative clinical and operative data were identical in both patient groups. Before cardiopulmonary bypass, serum protein concentrations were similar in all patients. Ten minutes after institution of cardiopulmonary bypass, protein concentrations fell to significantly lower values in patients with capillary leak syndrome than in those without: albumin (19% ± 1.5% vs 30% ± 6% of the prebypass value, p < 0.05), immunoglobulin G (17% ± 1.5% vs 29% ± 5.5%, p < 0.001), and α 2-macroglobulin (15% ± 1.2% vs 25% ± 4%, p < 0.02). During cardiopulmonary bypass, albumin concentrations remained significantly lower in patients with capillary leak syndrome than in those without, whereas hematocrit values were similar in both groups. During cardiopulmonary bypass, patients with capillary leak syndrome also had lower concentrations of complement proteins C3 and C4 but not C1 inhibitor. C3d/C3 ratio and C5a levels were similar in both patient groups. In contrast, histamine liberation during cardiopulmonary bypass was significantly more pronounced in patients with capillary leak syndrome than in those without (725.2 ± 396.7 pg/ml vs -54.1 ± 58.4 pg/ml, p < 0.05). Tumor necrosis factor-α levels after protamine administration were also significantly higher in patients with capillary leak syndrome (38.1 ± 10.0 pg/ml vs 15.3 ± 3.4 pg/ml, p < 0.05). Leukocyte count during and after cardiopulmonary bypass was similar in both patient groups. This study demonstrates increased protein leakage as early as 10 minutes after initiation of cardiopulmonary bypass in patients having clinical signs of postoperative capillary leak syndrome. Patients with capillary leak syndrome displayed more pronounced histamine liberation and tumor necrosis factor-α liberation than patients without capillary leak syndrome, suggesting a relationship between cardiopulmonary bypass-related inflammatory reaction and perioperative capillary damage. A preoperative inflammatory state in patients with capillary leak syndrome could have enhanced the inflammatory response to cardiopulmonary bypass. [less ▲]

We have recently demonstrated that bone sialoprotein (BSP), a bone-matrix protein involved in hydroxyapatite crystal formation, is ectopically expressed in human breast cancers. We explored a possible association between expression of BSP in primary breast cancer and patients' survival. We analyzed BSP expression in 454 breast-cancer patients by immunohistochemistry on archival paraffin-embedded material using an anti-BSP polyclonal antibody. BSP expression was correlated to survival, tumor size, axillary lymph-node status and first site of distant metastasis. Of the breast cancers analyzed, 89% expressed detectable amounts of BSP. We found a statistical association between expression of BSP and poor prognosis as indicated by survival curves analyzed using the log rank and the Gehan methods. BSP expression was significantly higher in breast-cancer patients with axillary lymph-node involvement. Interestingly, survival of patients with positive lymph nodes but BSP-negative tumors was significantly higher than that of patients with no lymph-node involvement but BSP-positive cancers. The frequency of bone metastases was higher in the group of patients with BSP-positive tumors (22%) than in the group with BSP-negative cancers (7%). There was a significant increase in the incidence of lung metastases in patients whose tumors were negative for BSP. Our data show that bone sialoprotein expression in breast cancer is associated with poor prognosis. BSP detection also appears to be a valuable marker with which to identify, among the lymph-node-negative patients, those who have high risk of disease progression. [less ▲]

We report a combined theoretical and experimental study of the interaction between a series of transition metals (Ni, Cu, Zn) and acrylonitrile. We demonstrate experimentally that the transition metal has a selective role in the grafting of electropolymerized acrylonitrile. Nickel and copper substrates support the formation of a polyacrylonitrile film, while zinc does not. Quantum chemical calculations indicate that acrylonitrile molecules form π-d bonds with Ni and Cu atoms, but do not react chemically with a Zn atom, in qualitative agreement with the experiment. Computational results also show that the electron affinity is significantly increased upon chemisorption, promoting radical anion species at the metal surface as initiators for polymerization.
