A self-made water purifying net, aeration stone, composite microbe preparation, and Ceratophyllum demersum were placed in the experimental ponds and the culture water was circulated along the raceway inside the pond using a paddle wheel aerator. In addition, the water quality in the experimental pond was improved by draining effluent from the pipeline at the bottom of ponds 7 and 8 （mode I） and exchanging the circulating water in pond 10 （mode Ⅱ） with the reservoir water in pond 9 using a pump and pipeline. The water quality in the experimental ponds was similar in response to regulation using mode Ⅰ or mode Ⅱ. Water quality parameters in the experimental ponds were controlled within a suitable range by simple facilities during culture period without using any chemical treatments. The rich content of dissolved oxygen was maintained by the circular flow and continuous aeration of the pond water. The respective average values of the main water parameters in experimental ponds 7 and 10 in response to regulation of the water quality using modes Ⅰ and Ⅱwere as follows： pH 8.17 and 7.99; DO 5.16 mg/L and 5.97 mg/L; CODMn18.45 and 12.61 mg/L; TAN （NH3-N） 0.854 mg/L （0.087 mg/L） and 0.427 mg/L （0.012 mg/L）; NO2-N 0.489 mg/L and 0.337 mg/L. Moreover, the average body length and body weight of harvested shrimp of pond 7 and pond l0 were 7.56 cm and 8.99 cm, 5.10 g and 8.33 g, respectively. Furthermore, the survival rate, average biomass yield and average condition factor of the shrimp harvested were 70% and 60%, 2.54 kg/m2 and 2.14 kg/m2, and 0.675 g/cm and 0.927 g/cm, respectively. Linear equations describing the relationship between body length and culture time and cubic or power functions describing the relationship between body weight and body length were obtained based on evaluation of the growth data of shrimps throughout the culture period.展开更多

A large number of autoantibodies have been detected in PSC patients,but the specifi city of these antibodies is generally low,and the frequencies vary largely between different studies. The presence of autoantibodies in PSC may be the result of a nonspecifi c dysregulation of the immune system,but the literature in PSC points to the possible presence of specifi c antibody targets in the biliary epithelium and in neutrophil granulocytes. The present review aims to give an overview of the studies of autoantibodies in PSC,with a particular emphasis on the prevalence,clinical relevance and possible pathogenetic importance of each individual marker.展开更多

Methods： Training for SG and VG consisted of twice-weekly 15-min sessions with average heart rates （HRs） of ～ 155 and 90 bpm respectively. Pre- and post-measurements of body composition （DXA）, phosphocreatine （PCr） on- and off-kinetics, and HR measurements during stand- ardised submaximal exercise were performed. Results： After 16 weeks of training in SG, fat percentage was lowered （p = 0.03） by 1.7%±2.4% from 37.5% ± 6.9% to 35.8% ± 6.2% and the PCr decrease in the quadriceps during knee-extension ramp exercise was attenuated （4% ± 8%, p = 0.04）, with no changes in VG or CO （time- group effect： p=0.03 and p = 0.03）. Submaximal exercise HR was also reduced in SG after 16 weeks of training （6%± 5% of HRmax, p = 0.01）. Conclusion： Short duration soccer training for 16 weeks appears to be sufficient to induce favourable changes in body composition and indicators of aerobic fitness and muscle oxidative capacity in untrained premenopausal women.展开更多
