BACKGROUND:Primary sclerosing cholangitis(PSC)is a chronic progressive cholestatic liver disease,which usually affects young adults and is diagnosed by *** a few occasions,the disease either starts in or exclusively involves the small intrahepatic bile ducts,referred to as small-duct PSC. METHODS:A 31-year-old man presented with severe hematemesis secondary to liver *** a course of 8 years,his liver decompensated and required an orthotopic liver transplantation. In this report we discuss his disease presentation,course of management,and the post-transplantation course of manage- ment,and review the morphologic diagnosis,and differential diagnosis of the disease with large-duct type and other diseases that involve small intrahepatic bile ducts. RESULTS:The patient’s explanted liver showed changes of PSC affecting only the small-and medium-sized bile ducts in addition to three incidental nodules of hepatocellular carcinoma. CONCLUSIONS:Small-duct PSC has a substantially better prognosis than the large-duct type,with less chance of developing cirrhosis and an equal risk for developing hepato- cellular carcinoma,but no increased risk for developing *** seems to help relieve the symptoms but not necessarily improve *** transplantation remains the ultimate cure.

There is a growing interest in sustainable and high performance supercapacitors(SCs) operating at elevated temperatures as they are highly demanded in heat-durable electronics. Here, we present a biomass-derived nonfluorinated ionic liquid(IL) [P_(4444)][HFuA] and its structural analogue [P_(4444)][TpA]as electrolytes for supercapacitors comprising multiwall carbon nanotubes and activated charcoal(MWCNTs/AC) mixed carbon composite electrodes. A detailed investigation of the effect of scan rate, temperature, potential window and orientation of ions on the electrodes surfaces is performed. The supercapacitors exhibited relatively lower specific capacitance for both [P_(4444)][HFuA] and [P_(4444)][TpA] ILs at room temperature. However, the specific capacitance has significantly increased with an increase in temperature and potential window. The equivalent serie resistances of the SCs is deceased with increasing temperatures, which is a result of improved ionic conductivities of the IL electrolytes. In CV cycling at60 °C, the capacitor with [P_(4444)][HFuA] IL-based electrolyte retained about 90% of its initial capacitance,while the capacitor with [P_(4444)][TpA] IL-based electrolyte retained about 83% of its initial *** computations revealed that the aromatic [FuA]^(-) and [TpA]^(-) anions displayed perpendicular distribution that can effectively neutralize charges on the carbon surfaces. However, the [HFuA]-anion exhibited somewhat tilted configurations on the carbon electrode surfaces, contributing to their outstanding capacitive performance in electrochemical devices.

With the advent of spinal cord epidural stimulation techniques,i.e.,electrically enabled motor control（e Emc）in combination with activity dependent locomotor training,humans with traumatic complete sensori-motor paralysis are able to initiate voluntary leg movements and achieve gains in postural control,and bladder and sexual function（Angeli et al.,2014）.

The dispersion relation is derived for three-dimensional dust-acoustic waves in a current-driven dusty plasmas with both positively and negatively charged dust particles. The dependencies of the frequency and the growth rate on the wave number K, the intensity of magnetic field B, and the inclination angle θ have been numerically shown in this paper. The growth rate is negative for the laboratory dusty plasma, but it is positive for the cosmic dusty plasma. It is found that when the inclination angle θ = π/2, there is no instability. The effect of the electrostatic field Eo has also been studied in this paper.

AIM: To measure a broad profile of pro-and anti-inflammatory cytokines in patients with clinically proven chronic pancreatitis (CP) taking either antioxidant therapy or placebo as part of the larger ANTICIPATE study. METHODS: Patients with chronic pancreatitis were recruited to the ANTICIPATE study following informed consent and were randomised to intervention with either antox version 1.2-based antioxidant therapy or placebo. After a separate ethics committee amendment a subgroup of 7 patients from either arm of the study were selected for additional analysis of cytokines. Cytokines were measured at baseline and after 6 mo of either antox therapy or placebo by biochip array and enzyme-linked immunosorbent assay. RESULTS: Antioxidant therapy and placebo groups were well-matched in terms of age, gender, aetiology of CP, opiate use and disease duration. Baseline antioxidant levels were similar in patients allocated to the antioxidant group as compared to the group al- located to placebo. After 6 mo of antioxidant therapythere was significant elevation in vitamin C levels in the intervention group: 17.6 μg/mL (12.8-29.3 μg/mL) compared to 4.8 μg/mL (1.6-9.1 μg/mL) in placebo (P < 0.001; 95%CI: 9.0-20.2) with similar trends in selenium levels. There was no elevation in a broad array of pro-and anti-inflammatory cytokines in the antioxidant group compared to placebo [interleukin (IL)-1B, IL-4, IL-6, IL-10, tumor necrosis factor-α] either at baseline or after 6 mo of antioxidant therapy. CONCLUSION: Cytokine levels were low at baseline and at 6 mo despite a significant elevation in plasma antioxidants. In patients with CP, with opiate-dependent abdominal pain, circulating cytokine levels are low suggesting that pain in this disease is not simply a manifestation of inflammation.
