Force plate analysis of ground reaction forces in relation to gait velocity of healthy Beagles

OBJECTIVE To evaluate changes in ground reaction forces (GRFs) in relation to gait velocity using 2 force plates (FPs) for healthy Beagles. ANIMALS 18 healthy Beagles were included (body weight, 10.45 ± 1.28 kg; age, 26 ± 11 months). PROCEDURES Ten GRF parameters were measured at three gait velocities (walk, 0.9 to 1.2 m/s; trot 1, 1.6 to 2.0 m/s; and trot 2, 2.1 to 2.5 m/s): peak lateral force (PLF), peak medial force (PMF), lateral impulse (LI), medial impulse (MI), peak propulsive force (PPF), peak braking force (PBF), propulsive impulse (PI), braking impulse (BI), peak vertical force (PVF), and vertical impulse (VI). RESULTS As velocity increased, the PVF of all limbs increased, the VI of all limbs decreased, and the PPF of the forelimbs increased. At all velocities, PBF and BI were significantly higher than the PPF and PI in forelimbs; however, PBF and BI were significantly lower than the PPF and PI in hindlimbs. There were no significant differences in the PLF, PMF, LI, and MI of the forelimbs and hindlimbs among all velocities. The PLF was significantly higher than the PMF of forelimbs during trot 1 and trot 2. CLINICAL RELEVANCE These results may be useful when comparing healthy Beagles with diseased ones when premorbid data are not available. Because the forelimbs are mainly responsible for the braking force, it is suggested that weight bearing is more stable in the forelimbs than in the hindlimbs, which are mainly responsible for the propulsive force, and that a greater force is generated laterally than medially during trot.journal articl

Carbohydrate control of nitrogen dynamics in decomposing leaf litter of temperate tree species

冷温帯林において、9樹種の落葉分解にともなう窒素動態を18ヶ月にわたって調べ、窒素動態に及ぼす炭水化物の含有量の影響を評価した。窒素の変化パターンは、落葉の積算重量減少に対する窒素濃度の相対的な変化率（NCIR）として評価した。9樹種の落葉の残存重量は指数的に減少し、18ヶ月後には初期重量の2.4〜40.7％となった。指数関数に当てはめたときの傾き（オルソンのk）は、0.74〜2.45/年であった。窒素の残存量は分解にともなって概ね減少したが、落葉重量に対する窒素濃度は一般に、落葉の積算重量減少に対して直線的に増加した（すなわち、NCIRは正の値）。9樹種のNCIRと、落葉の初期炭水化物濃度とのあいだに有意な正の相関関係が認められた。このことは、炭水化物が、分解者菌類が落葉に窒素を保持するための主要なエネルギー源となっていることを示唆している。Nitrogen (N) dynamics in decomposing leaf litter were elucidated for nine tree species over an 18-month period in a cool temperate forest and the effect of carbohydrate content on the N dynamics was evaluated. The pattern of changes in N was quantified in terms of the relative change of N content with respect to the accumulated mass loss of litter (known as Nitrogen Content Increase Rate or NCIR). The remaining mass of leaf litter of the nine tree species declined exponentially during the decomposition, and 2.4% to 40.7% of the original mass remained at the end of the 18-month period. Decomposition rate (as Olson's k) ranged from 0.74 to 2.45 year^-1. The remaining mass of N in leaf litter generally decreased with the decomposition, whereas the relative N content of leaf litter generally increased linearly with the accumulated mass loss of litter (i.e., NCIR values were positive). The NCIR of leaf litter was significantly and positively correlated with initial total carbohydrate content of litter, suggesting that carbohydrates served as a major energy source for decomposer fungi to retain N in decomposing litter.抄録(英語)の＾-1は上付き文字application/pdfdepartmental bulletin pape

GenoBase: comprehensive resource database of Escherichia coli K-12

Comprehensive experimental resources, such as ORFeome clone libraries and deletion mutant collections, are fundamental tools for elucidation of gene function. Data sets by omics analysis using these resources provide key information for functional analysis, modeling and simulation both in individual and systematic approaches. With the long-term goal of complete understanding of a cell, we have over the past decade created a variety of clone and mutant sets for functional genomics studies of Escherichia coli K-12. We have made these experimental resources freely available to the academic community worldwide. Accordingly, these resources have now been used in numerous investigations of a multitude of cell processes. Quality control is extremely important for evaluating results generated by these resources. Because the annotation has been changed since 2005, which we originally used for the construction, we have updated these genomic resources accordingly. Here, we describe GenoBase (http://ecoli.naist.jp/GB/), which contains key information about comprehensive experimental resources of E. coli K-12, their quality control and several omics data sets generated using these resources.journal articl
