6 ± 33.4, p = 0.025). The mean MSA survival time was 5.4 [95% confidence interval (CI) 4.8-6.3] years. Cox regression analysis showed that survival from baseline was correlated only with BCI [hazard ratio (HR) 0.983, 95% CI 0.969-0.997, p = 0.020]. Overall survival was correlated with BCI (HR 0.982, 95% CI 0.966-0.999, p = 0.039) and the presence of urinary incontinence (HR 3.007, 95% CI 0.993-9.220, p = 0.052). CONCLUSION Detrusor contractility can be a prognostic marker in MSA patients. A high BCI value is a protective factor for survival from baseline and overall survival. The presence of urinary incontinence predicts shortened overall survival.PURPOSE To define differences in heart rate and blood pressure variability (HRV/BPV) after spinal cord injury (SCI) compared with uninjured controls, and to determine whether variabilities are impacted by whole-body exercise after SCI. METHODS Individuals with SCI (n = 40), aged 18-40, and uninjured age/sex-matched controls (n = 22) had HRV and BPV determined during supine paced (0.25&nbsp;Hz) breathing. Spectral and cross-spectral values were derived for fluctuations at low (LF 0.05-0.15&nbsp;Hz) and high (HF 0.20-0.30&nbsp;Hz) frequencies. Thirty-two individuals with SCI further underwent either 6&nbsp;months of whole-body exercise training (n = 17) or a control intervention (n = 15). RESULTS Individuals with SCI had injuries graded A-C in severity, neurological levels of injury C1-T10. LF and HF HRV and LF BPV were significantly lower in individuals with SCI (p = 0.008-0.002), though HF BPV was similar. The LF cross-spectrum demonstrated similar phase and gain relationships between groups. The HF phase relationship between pressure and heart rate differed markedly individuals with SCI demonstrated a -11.7 ± 3.4° phase lag (241 ± 70&nbsp;ms feedback mechanism of pressure into heart rate), whereas uninjured controls demonstrated a +21.5 ± 10.8° phase lead (443 ± 224&nbsp;ms feedforward mechanism of heart rate into pressure, p = 0.007). Whole-body exercise increased mean VO2peak by 2.09&nbsp;ml/kg, whereas HRV, BPV, and their cross-spectral relationships were not significantly altered relative to the control intervention after SCI. CONCLUSION After SCI, marked frequency-specific differences exist in the relationship between heart rate and blood pressure variabilities. The high-frequency cross-spectral relationship indicates that a feedback mechanism of blood pressure into heart rate may predominate in this range.PURPOSE TXA9, a novel cardiac glycoside, has a potent anti-proliferative effect against A549 human lung cancer cells, however, possesses a poor water-solubility and a rapid metabolic rate in vivo which limited the further development of TXA9. To overcome the shortcomings of TXA9, four polymer prodrugs of TXA9 were designed and synthesized. METHODS Poly (ethylene glycol) monomethyl ether (mPEG) and α-tocopherol polyethylene glycol succinate (TPGS) were applied to modify TXA9 via carbonate ester and glycine linkers respectively to obtain four polymer prodrugs. The water-solubility and stability of prodrugs were studied in vitro while their pharmacokinetic behaviors and antitumor activity were investigated in vivo. RESULTS The water-solubility of TXA9 was obviously increased and prodrugs with glycine linkers showed a better stability in rat plasma. Their pharmacokinetic investigation found that the t1/2 and AUC0-∞ of TPGS-Gly-TXA9 was increased by 80- and 9.6-fold compared with that of TXA9, which was more superior than the other three prodrugs. More importantly, the tumor inhibition rate of TPGS-Gly-TXA9 (43.81%) on A549 xenograft nude mice was significantly increased compared with that of TXA9 (25.26%). CONCLUSION The above results suggested that TPGS-Gly-TXA9 possessed better antitumor efficiency than TXA9 and could be further investigated as an anti-cancer agent.An electrochemical immunosensor for the determination of porcine epidemic diarrhea virus (PEDV) is&nbsp;described. It was manufactured by using gold nanoparticles/molybdenum disulfide/reduced graphene oxide nanocomposites modified on the surface of a&nbsp;glassy carbon electrode (GCE). The independently developed monoclonal antibody of PEDV-2C11 was immobilized on the modified electrode at&nbsp;site of gold nanoparticles provided in the nanocomposites. The concentration of PEDV was quantified by measuring the changes in the charge transfer resistance of the electrode before and after the immunoreaction between antigen-antibody by using hexacyanoferrate(II)/(III) as the redox probe. The frequency range was 10-1 to 105&nbsp;Hz at the amplitude of 10&nbsp;mV and an&nbsp;applied potential of + 0.180&nbsp;V. Based on the immunoreaction between PEDV antigen and PEDV-2C11 antibody in 0.1&nbsp;M phosphate buffer containing 0.1&nbsp;M KCl at&nbsp;37.5&nbsp;°C for 140&nbsp;min, the relative change in impedance was proportional to the logarithmic value of PEDV concentrations in the range of 82.5 to 1.65 × 104 TCID50&nbsp;mL-1. Good&nbsp;reproducibility, stability, and specificity of the proposed immunosensor were obtained.

Among these patients, almost 15% will require a retransplantation surgery. This review aims to summarize the most recent information on different controversial issues regarding retransplantation, to provide the reader with a clear and updated view on the topic. RECENT FINDINGS Despite current evidence is mainly based on retrospective, small, single-center experiences, it seems clear that retransplantation remains a surgical and immunological challenge, for which the perioperative management still remains crucial to avoid mishaps. Different surgical approaches have been tested, but the general consensus advocates for the heterotopic extraperitoneal in first instance. Although higher immunological risk and complication rates are reported invariably in the available series, the benefits in terms of overall survival are superior to those obtained under dialysis, thus still representing the most recommended option for this group of patients.
