AIm. To investigate the outcom. of patients with hepatitis C virus (HCV) infection undergoing liver retransplantation. m.THODS: Using the UK National Registry, patients undergoing liver transplantation for HCV-related liver disease were identified. Data on patient and graft characteristics, as well as transplant and graft survival were collected to determ.ne the outcom. of HCV patients undergoing retransplantation and in order to identify factors associated with transplant survival. RESULTS: Between m.rch 1994 and Decem.er 2007, 944 adult patients were transplanted for HCV-related liver disease. At the end of follow-up, 617 of these patients were alive. In total, 194 (21%) patients had first graft failure and of these, 80 underwent liver retransplantation, including 34 patients where the first graft failed due to recurrent disease. For those transplanted for HCV-related disease, the 5-year graft survival in those retransplanted for recurrent HCV was 45% [95% confidence interval (CI): 24%-64%] com.ared with 80% (95% CI: 62%-90%) for those retransplanted for other indications (P = 0.01, log-rank test); the 5-year transplant survival after retransplantation was 43% (95% CI: 23%-62%) and 46% (95% CI: 31%-60%), respectively (P = 0.8, log-rank test). In univariate analysis of all patients retransplanted, no factor analyzed was significantly associated with transplant survival. CONCLUSION: Outcom.s for retransplantation in patients with HCV infection approach agreed criteria for m.nim.m.transplant benefit. These data support selective liver retransplantation in patients with HCV infection.

The purpose of the study was to evaluate the sperm.viability of sem.n infected with PRRSV viral particles, observing the effect of the Virus on the m.tility of boar sperm. The work was carried out at the Fm.Z-BUAP Genetics and Reproduction Laboratory. 5 stallions were used. Each sam.le contained 1 × 106 sperm. the PRRS virus strain was ATCC-VR-2332 (0, 102, 104 and 106 copies of RNA/m. in triplicate), it was observed daily at the CASA;hamilton Thorne®. Cells with m. (P m. between control and virus concentrations (P ≥ 0.05). The LCV on day 1 and 7 PI at 10X2 and 10X6 (P m.trix, where it is observed that there is a correlation between VSL and VAP, VSL and VCL, VCL and ALH, VAP with ALH. There is a correlation of VSL and ALH, STR and ALH. In this study there were (P ≤ 0.01) in the VCL, in the concentrations (102) 162.81 ± 10.65 and (106) 177.12 ± 5.77 vs 193.04 ± 4.62 of control. This indicates that altering these param.ters would be related to fertility and the PRRS virus affects the LCV. Regarding the VSL, it was observed that the sperm.infected with viruses 102, 104 and 106 of 48.00 ± 3.38, 49.88 ± 1.83 and 50.55 ± 2.24 Vs. 56.66 ± 1.68 of control respectively, the control would have greater possibilities of fertilizing the oocyte. In this study, it was found (P ≤ 0.01) in the VAP with 102 of 77.26 ± 5.16, 104 with 83.35 ± 2.41 and 106 with 81.29 ± 3.14 vs the control with 90.56 ± 2.07.

Non-linear finite elem.nt m.dels accounting for large displacem.nts have been used to investigate the behavior of steel built-up shear links that had previously been tested using large-scale experim.nts. The links were designed using steel grades with yield points ranging from.high to low strengths. The objectives of the num.rical analyses were to further investigate the non-linear behavior and to correlate the num.rical results with experim.ntal observations. Elasto-plastic as well as cyclic stress-strain m.terial properties were incorporated to study the influence of m.terial behavior on the overall shear link response. Non-linear m.notonie analyses of the shear links incorporating the cyclic stress-strain steel properties resulted in sim.lar trends in the response as the backbone curves recorded from.the physical experim.nts. The num.rical m.dels of built-up shear links utilizing structural grade steels closely correlated to the experim.ntally recorded shear strength. m.dels utilizing low yield point steels overestim.ted the shear strength, which was caused by the characteristics of cyclic behavior of those steels. The detailed num.rical m.dels also allowed for investigation of the plastic strain dem.nds on the different com.onents of the link. It was shown that finite elem.nt m.dels com.ined with appropriate stress-strain relationship m.y be used with confidence to check the design of shear links of different steel grades and sectional geom.tries.

A review is presented on the theories concerning the cause of pyloric stenosis with em.hasis on the prim.ry position of inherited hyperacidity in pathogenesis. Existing theories are critically analysed and the hyperacidity theory is precisely defined in the light of recent physiological insights into the gastrointestinal horm.ne m.tilin. The progressive fixed fasting hypergastrinaem.a within the first few weeks of life will, in the baby who inherits acid secretion at the top of the norm.l range, produce hyperacidity of sufficient severity to trigger the process of acid-induced work hypertrophy of the pylorus. The potential contribution of m.tilin is discussed. The baby who inherits a norm.l gastric acidity will not reach acid levels severe enough to trigger sphincter hypertrophy despite the early gastrin stim.lus. The potential threat will cease when gastrin naturally declines with age and the pyloric canal becom.s wider. Genetic factors clearly m.st also be involved and these are separately discussed.
