Maximum lignocellulose yield of biomass sorghum [Sorghum bicolor L. (Moench.)] is hampered by complex biological phenomena related to rotation, nitrogen (n) fertilization, soil tillage, and excessive biomass removal. The biochemical basis of the effects of agronomic practices on sorghum production was studied by the enzymology of the active peroxidase (EC 1.***.1.7) isoenzymes that synthesize lignin. All studied practices altered the peroxidase pI values. Control sorghum without rotation and without n fertilization had the most inhibited peroxidase with very low maximum velocity (Vmax) value (3.10 mmol·min﹣1), and very low lignin (857 kg·ha﹣1) yield, which could decrease soil organic carbon possibly leading to adverse changes in soil chemistry. Corn-sorghum rotations with and without n fertilization increased the Vmax values of peroxidase and lignin and cellulose yields. Rotated sorghum subjected to 50% residue return (the percentage of crop residue was returned to the plot immediately after grinding at harvest) and 280 kg·ha﹣1 n fertilization possessed very active peroxidase (Vmax value 66.4 mmole·min﹣1) and the highest lignin (1387 kg·ha﹣1) yield. The 25% residue return rate without n fertilization induced high lignin (1125 kg·ha﹣1) and cellulose (11,961 kg·ha﹣1) but the 25% residue return rate with 280 kg·ha﹣1 n fertilization induced lower lignin (1046 kg·ha﹣1) yield. Continuously cropped sorghum treated with 336 kg·n·ha﹣1 produced active peroxidase that shared competitive inhibition relationship with the peroxidase of the 84 kg·n·ha﹣1 treatment. Ridge tillage combined with 280 kg·ha﹣1 n fertilization under continuous sorghum resulted in inhibited peroxidase possessing low Vmax value (13.0 μmole·min﹣1). Changing to conventional tillage combined with 280 kg·ha﹣1 n fertilization relieved the inhibition and increased the Vmax value to 23.7 mmol·min﹣1. These biological anomalies of sorghum cell wall related to agronomic practices originated from doubly inhibited sorgh

Abstract： This study investigated the effects of three sport-specific high-intensity training units on cardiac biomarker alteration in elite athletes of dragon boating. Thirty six male （age 33 ± 9） and twenty nine female （age 31 ±8） elite athletes, members of the German national team, were examined in their final training camp preparing for world championship. At two time points blood panels （pre-training and one hour post-training） were collected and concentrations of high sensitive troponin T, n-terminal pro brain natriuretic peptide （nT-pro BnP）, ereatine phosphokinase （CPK）, MB-creatine kinase （CKMB） and myoglobin were assessed. After exercise, serum levels ofnT-pro BnP, CPK, myoglobin and CKMB increased significantly （P 〈 0.01 for each） with only few values exceeding the upper reference limits. High sensitive troponin T remained below the limit of detection both before and after exercise in all athletes. Significant gender-related differences were found with a higher increase ofnT-pro BnP levels in female athletes （P 〈 0.01） compared to males. In contrast, male athletes displayed a significant higher increase of CPK （P 〈 0.01） and myoglobin （P 〈 0.01） compared to female athletes. In conclusion, three high-intensity training units did not lead to elevated high sensitive troponin T concentrations in elite athletes of dragon boating but to significant increases ofnT-pro BnP, CPK and myoglobin levels. This suggests that high-intensity training units do not lead to a cardiac injury in these athletes.

Human-induced changes to natural landscapes have been identified as some of the greatest threats to freshwater resources. The change from natural forest cover to agricultural and pastoral activities is rampant especially in the upper Mara River catchment (water tower), as well as along the course of the Mara River. The objective of this study was to determine the effect of land use change on the physico-chemical properties of soil (bulk density, carbon, nitrogen, phosphorus and pH) along the course of the Mara River. Five major land uses (agricultural lands, livestock/pastoral lands, forested lands, conservancy/game reserves, and natural wetland) were explored. Results revealed that the mean soil bulk density was 0.956 g/cm3 and differed significantly between sites (p nificantly between sampling sites (land use types) within the Mara River Basin (F(4, 147) = 8.57, p n infiltration over a period of 150 minutes differed, not only among sampling sites, but also between different sides of the river (left and right) within the same sampling site. Soil pH was generally acidic across the five sites and varied significantly (F(4, 63) = 19.26, p tween sites along the Mara River Basin. The mean percentage soil nitrogen across all sampling blocks was 4.87%, with significant differences observed in percentage soil nitrogen (F (4, 63) = 3.26, p n sampling sites. The results indicated that the five land use types affected land degradation differently along the Mara River, while adjacent land degradation affected water physico-chemical properties. These results point to the need to have focused policies on integrated land and water resource management strategies in the Mara River Basin.

用形态计量学方法对口腔颊粘膜的正常粘膜上皮(n)、慢性非特异性炎症(IF)、单纯性过角化(HK)、纤维增生(FH)、扁平苔藓(LI)、白斑(LP)、乳头状瘤(PP)、癌旁上皮(CE)、鳞癌癌巢(CI)的上皮基底层细胞及胞核的大小(包括体积、面积和胞核/胞浆比值)、进行了测量和形态计量相关分析(MCA)。结果显示 CI 组在分布图上最偏离 n 组,其次是 CE 组,LI 与 LP 组位置非常接近并邻近于 CE和 CI 组;此外发现 IF,FH,HK 及 PP 组与 n 组的位置最为接近。对于病变个体的 MCA 分析显示 n 组最为集中,IF,FH,HK 及 PP 的分布相对比较集中,围绕或与 n 组相重叠;而 CI 组与 n 组无重叠且偏离一边,LI,LP 及 CE 组位于 CI 与 n 及其它良性病变组之间并部分与 CI 重叠。本文结果揭示通过 MCA方法可以较好的反映颊部粘膜各病变所处的病变状态、各病变之间的关系以及个体病变的病变程度。应用 MCA 的方法将有助于癌前病变的早期发现以及确定癌变组内的不同级别。
