AIm To assess the functionality of congenital coronary artery fistulas(CAFs) using adenosine stress ^(13)N-ammonia positron emission tomography computed tomography(PET-CT).mETHODS Congenital CAFs were incidentally detected during coronary angiography(CAG) procedures in 11 adult patients(six males and five females) with a mean age of 64.3 years(range 41-81). Patients were collected from three institutes in the Netherlands. The characteristics of the fistulas(origin, pathway and termination), multiplicity of the origins and pathways of the fistulous vessels were assessed by CAG. Five patients underwent adenosine pharmacologic stress ^(13)N-ammonia PET-CT to assess myocardial perfusion and the functional behavior of the fistula. RESULTS Eleven patients with 12 CAFs, 10 unilateral and one bilateral, originating from the left anterior descending coronary artery(n = 8), right coronary artery(n = 2) and circumflex(n = 2). All fistulas were of the vascular type, terminating into either the pulmonary artery(n = 11) or coronary sinus(n = 1). The CAG delineated the characteristics of the fistula(origin, pathway and termination). multiplicity of the origins and pathways of the fistulous vessels were common in most fistulas(8/12, 67% and 9/12, 75%, respectively). multiplicity was common among the different fistula components(23/36, 64%). Adenosine pharmacologic stress ^(13)N-ammonia PET-CT revealed normal myocardial perfusion and ejection fraction in all but one patient, who showed a reduced ejection *** PET-CT may be helpful for assessing the functional status of congenital CAFs in selected patients regarding clinical decision-making. Studies with a larger patient series are warranted.

The structural diversity of different tree-crop associations were studied at Gachabari Sal forest area of madhupur Garh on Buffer and Peripheral Zone during 2006. The total density, basal area of trees in the Buffer and Peripheral Zone were 155.5 trees·hm^(-2), 795.4 trees·hm^(-2) and 3.9 m2·hm-2, 5.8 m^2·hm^(-2), respectively. No regeneration and natural trees were found in Peripheral Zone and the Zone is totally occupied by exotic species where the Buffer Zone comprised of both natural and exotic trees. The Peripheral Zone belonged to younger and smaller trees whereas the Buffer Zone belonged to mixture of smaller, taller, younger and mature trees simultaneously. For the practicing of different agroforestry systems both Zones have lost their original characters of Sal forest.

作者： Usman Afzal muhammad Shahid Ibni Zamir Shan mohi ud Din Aqib Bilal muhammad Salahuddin Shahid Iqbal Khan Department of Agronomy University of Agriculture Faisalabad Pakistan Department of Botany University of Agriculture Faisalabad Pakistan

To evaluate the impact of different zinc application methods on yield and yield components of various wheat cultivars, a field experiment was carried out at Student’s Farm, Department of Agronomy, University of Agriculture Faisalabad, during winter 2014-2015. The experiment was laid out in RCBD (Randomized Complete Block Design) with factorial arrangement. In this experiment, all the treatments were replicated three times, using the net plot size of 1.8 m × 5.0 m. The experiment comprised of two factors. Factor A consists of two varieties: Faisalabad-2008 and Punjab-2011. While, Factor B consists of different methods of zinc application, control, zinc application in soil before planting 23 kg·ha-1, zinc foliar application, 4% ZnSO4 solution at two stages (tillering and stem elongation stage). The data regarding different parameters were collected and analyzed from the crop using standard procedures. Regarding the impact of zinc application method maximum plant height at maturity (103.6 cm), total number of tillers (564.67 m-2), spike length (10.83 cm), number of spikelets spike-1 (19.50), number of grains spike-1 (50.36), 1000-grain weight (34.16 g), biological yield (11.93 t·ha-1), grain yield (6.00 t·ha-1) and harvest index (39.25%) were recorded in treatment where zinc was applied both in the soil before planting and by foliar application on later growth stages. Similarly, grain zinc contents (33.11 mg·kg-1), grain protein contents (10.1%) and grain carbohydrate contents (64.23%) were also observed in the treatment where zinc was applied both in the soil before planting and by foliar application on later growth stages, which is better than all other treatments. In case of wheat varieties, Faisalabad-2008 performed better than Punjab-2011, with maximum method maximum total number of tillers (460.67 m-2), spike length (9.70 cm), number of grains spike-1 (48.80), 1000-grain weight (33.81 g), biological yield (10.32 t·ha-1), grain yield (5.0 t·ha-1) and harvest index

引用

American Journal of Plant Sciences 2018年第9期9卷 1781-1793页

作者： Naveed Islam muhammad Shahid Ibni Zamir Shan mohi ud Din Umer Farooq Haseeb Arshad Aqib Bilal muhammad Talha Sajjad Department of Agronomy University of Agriculture Faisalabad Pakistan Department of Botany University of Agriculture Faisalabad Pakistan

A field study was scheduled to estimate the impact of intercropping of pearl millet with cowpea on forage yield and quality at Agronomy Research Farm, University of Agriculture, Faisalabad. It was done in kharif season 2016. Randomized complete block design was used to conduct this experiment. It has three replications. The size of net plot is 3.6 m × 6 m. It comprised of five treatments (T1 = one row of millet alternating with one row of cowpea (1m:1C), T2 = two rows of millet alternating with one row of cowpea (2m:1C), T3 = one row of millet alternating with two rows of cowpea (1m:2C), T4 = sole millet, T5 = sole cowpea). We found that intercropping significantly effected the yield and quality of forage. Intercropping system had significant effects on nutritive value of forage crop. Within various treatments of intercropping, it is evident that treatment T2 (two rows of millet alternating with one row of cowpea) gives maximum total dry matter yield (9.68 t ha-1). It was then tracked by treatment T1 (one row of millet alternating with one row of cowpea) and treatment T3 (one row of millet alternating with two rows of cowpea) producing dry matter yield (9.07 t ha-1 and 8.33 t ha-1, respectively). Based on high grain and suitable environmental condition, intercrop productivity compared to sole crop could be selected for improving the productivity of millet/cowpea mixture in the Punjab.

作者： Knebel F. Bhm m. Staudt A. 艾文婷 med. Klinik der Charité Humboldt-Universitt Zu Berlin Schumannstr. 20/21 10117 Berlin Germany

Background: In patients with dilated cardiomyopathy (DCm)-and severe congestive heart failure, immunoadsorption(IA) and subsequent IgG substitution leads to an acute and prolonged hemodynamic improvement. Goal of this study was to investigate the long-term effect of immunoadsorption on morbidity. methods: In a retrospective analysis of 34 patients(17 patients who have received immunoadsorption therapy and 17 control patients) were included. Inclusion criteria were DCm, left ventricular ejection fraction less than 35%, NYHA classes II-III. The average time after immunoadsorption was 3.0 years (median 2.3 years). Both groups did not differ concerning sex, age, duration of disease, medication, baseline ejection fraction and NYHA class. Results: In patients who have received immunoadsorption(IA) the days of hospitalisation for congestive heart failure per year could be significantly reduced in contrast to the control patients(17.2 days prior to IA, 4.3 days after IA). Even if the procedural days for immunoadsorption were included there was still a significant reduction of hospitalisation if IA therapy was longer than 2.5 years ago. The days of hospitalisation increased gradually with time during the follow up period. IA induced an acute increase in EF(19.8-25.7%, pmodynamic improvement in patients with DCm but may also reduce morbidity in these patients during the next 3 years.

Journal of Environmental Sciences 2001年第4期13卷 502-507页

作者： Yan, W.-j. Huang, m.-x. Zhang, S. Tang, Y.-j. Dept. of Envrn. Biogeochemistry Inst.Geographic Sci./Nat. Rsrc. Res. Chinese Academy of Sciences Beijing 100101 China

Runoff and soil losses from agricultural fields are investigated as major nonpoint sources of phosphorus (P) entering lakes of Eastern China. There is relatively little information on P transport from ricefield and cropland of Lake Taihu watershed in Eastern China. Soil and P in surface runoff from a series of plots in the watershed were evaluated under simulated rainfall conditions. The objectives of this study were to evaluate the effects of crop cover, slope, and fertilizer application on P concentrations in surface runoff and eroded soil. Accumulated sediment yields varied from 7.1 to 300 g/m2 for croplands, depending on management practices. For all experiment plots, weighted average concentrations of total-P (TP), dissolved P (DP) and particulate P (PP) are much higher than 0.02 mg/L, the limiting concentration for lake water. This result showed the potential contamination of lake water from agricultural surface runoff. Accumulated TP losses were 3.8 and 18.8 mg/m2 for ricefield and cropland, respectively. The estimated annual loss of TP was 0.74 kg/(hm2 · a) for cropland. most of P loss is in the PP form, which accounts for more than 90% of TP loss for cropland.
