The aim of this study was to analyze cartilage creep and creep recovery after static and cyclic loading. Up to now technical limitations have hindered the measurement of creep recovery. For this reason, we developed a closed loop micro creep and creep-recovery indentation test system with active force control. Bovine osteochondral explants were tested under static （110 kPa） and cyclic （100 cycles, 350 kPa/35 kPa, 1 Hz） loading conditions and subsequently creep recovery was measured. The cartilage thickness was determined using needle indentation. For static loading, the creep and creep-recovery rates were significantly different during the first 60 seconds （p 〈 0.05）. Cyclic loading was assessed for the medial and lateral patella and resulted in a physiological patellar cartilage strain of 7.7% ± 2.6% and 8.2% ± 2.7%, respectively. We recorded a creep recovery of 97.8% ±2.1% for the medial and 98.3% ± 2.4% for the lateral patella. The advantage of this study over earlier in vitro studies is that we recorded creep-recovery profiles with an actively controlled setup. This allowed us to analyze creep recovery immediately after removing the creep load, in contrast to MRI-based in vivo studies. In future, the presented method will enable us to quantify spatial variations within articular joints.

The partitioning of nitrogen deposition among forest soil （including forest floor）, leachate and above- and belowground biomass of pot cultured beech seedlings in comparison to non-cultured treatments were investigated by adding 1.92 g.m^-2 ^15N tracer in throughfall for two successive growing seasons at a greenhouse experiment. Ammonium and nitrate depositions were simulated on four treatments （cultured and non-cultured） and each treatment was labeled with either ^15N-NH4^＋ or ^15N-NO3^-. Total recovery rates of the applied ^15N in the whole system accounted for 74.9% to 67.3% after ^15N-NH4^＋ and 85.3% to 88.1% after ^15N-NO3^-in cultured and non-cultured treatments, respectively. The main sink for both ^15N tracers was the forest soil （including forest floor）, where 34.6% to 33.7% of ^15N-NH4^＋ and 13.1% to 9.0% of ^15N-NO3^-were found in cultured and non-cultured treatments, respectively, suggesting strong immobilization of both N forms by hetero- trophic microorganisms. Nitrogen immobilization by microorganisms in the forest soil （including forest floor） was three times higher when ^15N-NH4^＋ was applied compared to ^15N-NO3^-. The preferential heterotrophic use of ammonium resulted in a two times higher retention of deposited ^15N-NH4^＋ in the forest soil as compared to plants. In contrast, nitrate immobilization in the forest soil was lower compared to plants, although statistically it was not significantly different. In total the immobilization of ammonium in the plant-soil system was about 60% higher than nitrate, indicating the importance of the N-forms deposition for retention in forest ecosystems.

＜正＞Post-translational modification of proteins plays a central role in many important intracellular processes, e.g. signal transduction. Therefore, a detailed understanding of the regulation, nature, and occurrence of the modifications is the key to an understanding of the molecular mechanisms of cell signaling, both, under physiological and pathophysiological conditions.

由于人们过度使用化学农药防治植物病害造成了土壤污染和对人类的健康产生了不利的影响。因此,生物防治植物病害引起了人们的关注。在很多的实验中应用PGPR菌株其中包括Bacillus菌株处理植物能够增加作物产量和降低植物病害。Bacillus subtilis和Bacillus amyloliquifaciens能够合成抗真菌的多肽,如脂肽类化合物;合成促进植物生长的物质,如赤霉素和吲哚乙酸;诱导植物产生系统抗性。西藏地区耕地面积极其有限,仅占整个西藏土地面积的约0.5%,且该地区平均海拔4000米以上,低温,但光照天数多。因此西藏地区适合发展设施农业。近年来,大棚蔬菜在西藏地区得到了快速的发展,但是连续种植单一农作物容易引起严重的土传病害。于是我们尝试应用植物有益微生物Bacillus spp.促进植物生长及防治植物土传病害。据我们所知,这是首次应用生物农药在本地区。Bacillus subtilis 69 and B3菌株来源于本试验室,*** FZB24 and FZB42制剂来源于德国Abitep公司。本试验中我们用Bacillus subtilis 69 and B3细胞悬浮液,以及*** FZB24和FZB42制剂防治大棚内土传真菌病害。我们分别对西瓜进行种子处理和苗期灌根,结果显示处理明显地促进了西瓜的生长,同时有效的控制了病害的发生。一方面,所有处理都明显的促进了西瓜种子的萌发,平均萌发率增加了16%。另一方面,在发芽8周后,所有处理都有效的促进了西瓜茎长、茎粗和叶片数,平均茎长增长了15.3%,茎粗增长了19.8%,叶片数增加了20%。此外,在移植10周后,所有处理都明显的促进了西瓜的生长和有效的防治了西瓜枯萎病的发生。处理后的结果率和单果重分别平均增加了86.8%和74.2%;病害严重度平均减少了55%。收获后西瓜产量平均增加了15%。另外,我们用MALDI-TOF-MS对Bacillus subtilis 69产生的脂肽类化合物进行了分析,结果表明:Bacillus subtilis 69能够产生surfactin和fengycins。试验结果垃示,在西藏地区大棚中Bacillus类微生物能够有效地促进西瓜生长,增加西瓜产量和防治西瓜土传病害。用MALDI-TOF-MS对Bacillus subtilis 69产生的脂肽类化合物进行了分析,结果表明,土传真菌病害的防治可能依赖于菌株产生的脂肽类化合物。

14-3-3 proteins play an important role in the regulation of many cellular processes. The Arabidopsis vacuolar two-pore K＋ channel 1 （TPK1） interacts with the 14-3-3 protein GRF6 （GF14-λ）. Upon phosphorylation of the putative binding motif in the N-terminus of TPK1, GRF6 binds to TPK1 and activates the potassium channel. In order to gain a deeper understanding of this 14-3-3-mediated signal transduction, we set out to identify the respective kinases, which regulate the phosphorylation status of the 14-3-3 binding motif in TPK1. Here, we report that the calcium-dependent protein kinases （CDPKs） can phosphorylate and thereby activate the 14-3-3 binding motif in TPK1. Focusing on the stress-activated kinase CPK3, we visualized direct and specific interaction of TPK1 with the kinase at the tonoplast in vivo. In line with its proposed role in K＋ homeostasis, TPK1 phosphorylation was found to be induced by salt stress in planta, and both cpk3 and tpkl mutants displayed salt-sensitive phenotypes. Molecular modeling of the TPK1-CPK3 interaction domain provided mechanistic insights into TPK1 stress-regulated phosphorylation responses and pinpointed two arginine residues in the N-terminal 14-3-3 binding motif in TPK1 critical for kinase interaction. Taken together, our studies provide evidence for an essential role of the vacuolar potassium channel TPK1 in salt-stress adaptation as a target of calcium-regulated stress signaling pathways involving Ca2＋, Ca2＋-dependent kinases, and 14-3-3 proteins.

Historically,ground calcined aluminas were the first high-alumina matrix products that were used in refractory formulations, in both shaped and unshaped products. At that time the flow properties of castables were enhanced by the use of silica fume. This was followed later by the development of fully ground reactive aluminas which contributed to the design of the matrix below 63 μm. In addition to aggregate fines,a range of bi-modal and multi-modal reactive aluminas were also developed. These not only gave improved physical properties but also better castable workability. This paper reviews matrix alumina developments over time,from basic ground calcines to complex multi-modal matrix products and their globally standardised manufacture.
