Background： A novel extruded product was characterized with a metabolism and lactation trial to establish the product＇s energy content, and its effects on lactating sow performance. The product was composed of a 60：40 corn-soybean blend, which was then extruded. This product containing the co-extruded 60：40 corn-soybean blend was commercially developed and is used extensively in swine diets in southwest Minnesota. GE of dietary treatments were determined by isoperibol bomb calorimetry. Twelve barrows （59.9 ± 1.4 kg）, were used to determine the digestible and metabolizable energy of the extruded product. DE of treatments was determined by subtracting fecal energy from GE provided to barrows by each respective treatment. ME was determined by subtracting urinary energy from calculated digestible energy. Sixty-three sows were used for the lactation trial. Three dietary treatments were utilized： CONTrOL （an industry standard diet）; PrODUCT （contained the product, vitamins and minerals）; OIL （matched the lysine：ME ratio of PrODUCT by addition of soy oil）. Sow weight, backfat thickness at the right and left last ribs, body condition score, number of piglets, and litter weights were recorded on the date of farrowing （d 0）, （d 9）, and at weaning. Blood and milk samples were obtained at weaning, and blood was analyzed for plasma urea nitrogen （PUN）, milk was analyzed for total protein and fat content. results： On a dry-matter basis, the test diet provided 3,908 kcal/kg DE and 3,833 kcal/kg ME, which was significantly greater than the basal diet, which provided 3,633 kcal/kg DE and 3,567 kcal/kg ME （P 〈 0.0001）. These data were used to establish the DE and ME of the product, which were 3,882 kcal/kg and 3,798 kcal/kg, respectively, on an as-fed basis. No effect of diet was observed for changes in sow backfat （rBF P = 0.24; LBF P = 0.07） or body condition score （P = 0.12） during lactation. Milk total protein （P = 0.69）, fat （P = 0.66）, PUN, average piglet gain （P = 0.55） and pi

利用黏弹塑性有限元分析方法 ,模拟了厚为 1 0km的上地壳 (假定上地壳具有Byerlee型强度包络 )中以逆断层为边界的盆地的演化 ;假定基底无黏性 ,而盆地中充填的沉积物密度比地壳密度小 40 0kg/m3 。随着每次以 0 .2 5km位移增量逐渐挤压地层 ,塑性破裂区扩大 ,直至挤压位移至约 5 .5km时 ,出现了破裂切穿整个地层的现象。当达到这种状态时 ,盆地的沉降减慢 ,最终停止。地层被挤压至位移 5 .5km后形成一个 30km宽、5km深的盆地。整个演化过程中 ,盆地转折线逐渐向断层移动。切穿破裂出现以后 ,地层被继续挤压到位移 8km ,以便观察研究断层两侧的挤压褶皱构造。这些褶皱是从早期轻微的挠曲起伏演化而来的 ,到挤压位移 3km时 ,它们开始明显增强 ,到挤压位移 8km时 ,已经形成非常大的背斜和向斜 ,其幅度从断层向两侧逐渐减小。

A cure cannot be assured for all men with clinically localized prostate cancer undergoing radical treatment. Molecular markers would be invaluable if they could improve the prediction of occult metastatic disease. This study was carried out to investigate the expression of BCL-2, Ki-67, p53 and E-cadherin in radical prostatectomy specimens. We sought to assess their ability to predict early biochemical relapse in a specific therapeutic setting. Eighty-two patients comprising 41 case pairs were matched for pathological stage, Gleason grade and preoperative prostate-specific antigen （PSA） concentration. One patient in each pair had biochemical recurrence （defined as PSA ≥ 0.2 ng mL^-1 within 2 years of surgery） and the other remained biochemically free of disease （defined as undetectable PSA at least 3 years after surgery）. Immunohistochemical analysis was performed to assess marker expression on four replicate tissue microarrays constructed with benign and malignant tissue from each radical prostatectomy specimen. Ki-67, p53 and BCL-2, but not E-cadherin, were significantly upregulated in prostate adenocarcinoma compared with benign prostate tissue （P 〈 0.01）. However, no significant differences in expression of any of the markers were observed when comparing patients who developed early biochemical relapse with patients who had no biochemical recurrence. This study showed that expression of p53, BCL-2 and Ki-67 was upregulated in clinically localized prostate cancer compared with benign prostate tissue, with no alteration in E-cadherin expression. Biomarker upregulation had no prognostic value for biochemical recurrence after radical prostatectomy, even after considering pathological stage, whole tumour Gleason grade and preoperative serum PSA level.
