Reliability of the Chinese version of the 7-day recall physical activity questionnaire and its correlation with impairments of disease and function
No full textGrowth, biomass partitioning, and water-use efficiency of a leguminous shrub (Bauhinia faberi var. microphylla) in response to various water availabilities
No full textResponses of the endemic leguminous shrub Bauhinia faberi var. microphylla, to various soil water supply regimes were studied in order to assess water stress tolerance of seedlings. Two-month-old seedlings were grown under water supply regimes of 100, 80, 60, 40, and 20% water field capacity (FC), respectively, in a temperature and light-controlled greenhouse. Plant height and leaf number were measured monthly over a 4-month period, while water use (WU), water-use efficiency (WUE), leaf relative water content (RWC), biomass production and its partitioning were recorded at the end of the experiment. Seedlings exhibited the greatest biomass production, height, basal diameter, branch number, leaf number, and leaf area when soil content was at 100% FC, and slightly declined at 80% FC. These parameters declined significantly under 60% FC water supply, and severely reduced under 40 and 20% FC. RWC, WU and WUE decreased, while the ratio of root mass to stem mass (R:S) increased in response to decreasing water supply. Water stress caused leaf shedding, but not plant death. The results demonstrated that B. faberi var. microphylla seedlings could tolerate drought by reducing branching and leaf area while maintaining a high R:S ratio. However, low dry mass and WUE at 40 and 20% FC suggested that the seedlings did not produce significant biomass under prolonged severe water deficit. Therefore, before introducing B. faberi var. microphylla in vegetation restoration efforts, water supply above 40% FC is recommended for seedlings to maintain growth

No full text[[abstract]]The apolipoprotein E knockout (apoE-/-) mice are hyperlipidemic and a good model to study atherosclerosis. In order to know the effects of wild bitter gourd on lipid metabolism, we conducted two experiments in apoE-/- mice. In experiment 1, 18-wk-old apoE-/- mice were assigned to 6 groups and fed different diets as follows: the high fat (20%, w/w) diet (HF, n = 10), HF with 5%wild bitter ground powder (BGP, n = 10), HF with 1% ethyl acetate extract of bitter gourd (EAE, n = 10), HF with 0.5% clofibrate (CF, n = 5), HF with 0.00123% rosiglitazone (TZD, n = 5) and chow diet (C, n = 5). Serum total cholesterol (TC) and triglyceride (TG) concentrations were measured at the end of wk 4, 9 and 17. After 18 wk of feeding, the mice were sacrified. Liver and blood samples were obtained to determine hepatic TC, TG and serum HDL-C concentrations. Data were analyzed by one-way analysis of variance and the Tukey post hoc. The BGP group had a lower level of serum total cholesterol in week 9 and 17 (25 & 39% reduction, respectively, p<0.05), a lower level of serum triglyceride in week 17 (38% reduction, p<0.05) and a higher level of HDL-C in wk 18 (55% increase, p<0.05) than the HF group. The EAE group had a 39% higher level of HDL-C than the HF group in week 18, but it was not statistically significant. Levels of hepatic TC and TG were not significantly different among all groups. In experiment 2, young (6-10 wk-old) apoE-/- mice were assigned to 3 groups and fed the HF diet (n = 11), the BGP diet (n = 9) and the EAE diet (n = 10), respectively, for 8 wk. After feeding trials, the BGP group had a lower level of serum total cholesterol (28% reduction, p<0.05), and a larger decrease in level of serum triglyceride in wk 8 (p<0.05) than the HF group. The BGP group also had a 25% higher level of HDL-C than HF group, but it was not statistically significant. There were no significant difference in serum adiponectin, serum leptin, liver PPAR-αmRNA expression and liver MTP mRNA expression among HF、BGP and EAE groups. In conclusion, this study shows that wild bitter gourd powder can be a potent blood lipid-lowering health food.
FET ACTIVE SLOTLINE NOTCH ANTENNAS FOR QUASI-OPTICAL POWER COMBINING
No full textA new active antenna structure with applications in quasi-optical power combining is described. The active antenna combines a slotline FET oscillator with a notch antenna. The new structure was successfully used to create both E-plane and H-plane linear arrays as well as a 2-D array. Preliminary results of radiation patterns and the power combining efficiencies of the arrays are discussed
Carbon accumulation, nitrogen and phosphorus use efficiency of Sophora davidii seedlings in response to nitrogen supply and water stress
No full textA greenhouse experiment was conducted to explore whether additional nitrogen (N) supply could enhance carbon (C) accumulation, and phosphorus (P) use efficiency (NUEp) of Sophora davidii seedlings under dry conditions. Two-month-old seedlings were subjected to a completely randomized design with three water (80, 40 and 20% water field capacity (FC)) and three N supply (N0: 0, Nl: 92 and Nh: 184 mg N kg(-1) soil) regimes. Water stress decreased C, N and P accumulation, NUEP, N and P uptake efficiency (NUtE(N) and NUtE(P)) regardless of N supply. The S. davidii seedlings exhibited strong responses to N supply, but the responses were not consistent with the various N supply levels. Nl increased C, N and P accumulation, and improved NUEP, NUtE(N) and NUtE(P) in the same water treatment. In contrast, Nh did few or even depress effects on C, N and P accumulation, and NUEp, although NUtE(N) and NUtE(P) increased with Nil in the same water treatment. Even so, NUEN decreased with increase of N supply in the same water treatment. The results suggested that appropriate or low N supply should be recommended for S. davidii seedling establishment in dry environment by improving C accumulation and NUEP. (C) 2009 Elsevier Ltd.

Effects of water stress and nitrogen supply on leaf gas exchange and fluorescence parameters of Sophora davidii seedlings
No full textTwo-month-old seedlings of Sophora davidii were subjected to a randomized complete block design with three water (80, 40, and 20 % of water field capacity, i.e. FC80, FC40, and FC20) and three N supply [N0: 0, Nl: 92 and Nh: 184 mg(N) kg(-1)(soil)] regimes. Water stress produced decreased leaf area (LA) and photosynthetic pigment contents, inhibited photosynthetic efficiency, and induced photodamage in photosystem 2 (PS2), but increased specific leaf area (SLA). The decreased net photosynthetic rate (P (N)) under medium water stress (FC40) compared to control (FC80) might result from stomatal limitations, but the decreased P (N) under severe water deficit (FC20) might be attributed to non-stomatal limitations. On the other hand, N supply could improve photosynthetic capacity by increasing LA and photosynthetic pigment contents, and enhancing photosynthetic efficiency under water deficit. Moreover, N supply did a little in alleviating photodamages to PS2 caused by water stress. Hence water stress was the primary limitation in photosynthetic processes of S. davidii seedlings, while the photosynthetic characters of seedlings exhibited positive responses to N supply. Appropriate N supply is recommended to improve photosynthetic efficiency and alleviate photodamage under water stress
