Objectives: The purpose of this study was to evaluate and compare the use of propinox hydrochloride and scopolamine hydrochloride in patients presenting abdominal colic (abdominal pain), in terms of treatment efficacy and tolerability. Material & Methods: This was an analytical, retrospective, comparative study based on hospital records of outpatients treated at Serviço de Clínica Médica do Hospital das Clínicas Costantino Otaviano (HCTCO) and at Santa Casa de Misericórdia do Rio de Janeiro, from 1988-1998. Subjects were divided into two groups: patients from Group 1 were treated with propinox hydrochloride, while patients from Group 2 were treated with scopolamine hydrochloride. Statistical analysis was performed using GraphPad Prism version 5.0. For comparison of categorical variables, we used the chi-squared or Fisher’s test, while continuous variables were analyzed using ANOVA or the Student’s T test. Results: A total of 1042 subjects were included, of which 525 were allocated to Group 1 and 517 to Group 2. Mean treatment duration was 9.166 days (±4.208) in Group 1 and 8.795 days (±5.052) in Group 2, with no statistically significant difference in treatment duration between the two groups (p = 0.198). All subjects in Group 1 were treated with propinox 10 mg (2 coated tablets, three times per day) while all subjects in Group 2 were treated with scopolamine hydrochloride 10 mg (2 coated tablets, three times per day). There were no statistically significant between-group differences in weight, BMI, heart rate, and respiratory rate at pre- and post-treatment;with the exception of higher post-treatment systolic blood pressure in Group 1, blood pressure measures also remained homogenous. Adverse events were reported among both treatment groups with no significant between-group difference in incidence (p = 0566). At pretreatment, pain intensity was more severe in Group 1 (p = 0.0257), while at post-treatment, there was no statistically significant difference betw

Subsoil acidity restricts root growth and reduces crop yields in many parts of the world. More than half of the fertilizer nitrogen(N) applied in crop production is currently lost to the environment. This study aimed to investigate the effect of gypsum application on the efficiency of N fertilizer in no-till corn(Zea mays L.) production in southern Brazil. A field experiment examined the effects of surface-applied gypsum(0, 5, 10, and 15 Mg ha^(-1)) and top-dressed ammonium nitrate(NH_4NO_3)(60, 120, and 180 kg N ha^(-1)) on corn root length, N uptake, and grain yield. A greenhouse experiment was conducted using undisturbed soil columns collected from the field experiment site to evaluate NO_3-N leaching, N uptake, and root length with surface-applied gypsum(0 and 10 Mg ha^(-1)) and top-dressed NH_4NO_3(0 and 180 kg N ha^(-1)). Amelioration of subsoil acidity due to gypsum application increased corn root growth,N uptake, grain yield, and N use efficiency. Applying gypsum to the soil surface increased corn grain yield by 19%–38% and partial factor productivity of N(PFPN) by 27%–38%, depending on the N application rate. Results of the undisturbed soil column greenhouse experiment showed that improvement of N use efficiency by gypsum application was due to the higher N uptake from NO_3-N in the subsoil as a result of increased corn root length. Our results suggest that ameliorating subsoil acidity with gypsum in a no-till corn system could increase N use efficiency, improve grain yield, and reduce environmental risks due to NO_3-N leaching.

ATLAS LAr calorimeter will undergo its Phase-I upgrade during the long shutdown（LS2） in 2018, and a new LAr Trigger Digitizer Board（LTDB） will be designed and installed. Several commercial-off-the-shelf（COTS）multi-channel high-speed ADCs have been selected as possible backups of the radiation tolerant ADC ASICs for the LTDB. To evaluate the radiation tolerance of these backup commercial ADCs, we developed an ADC radiation tolerance characterization system, which includes the ADC boards, data acquisition（DAQ） board, signal generator,external power supplies and a host computer. The ADC board is custom designed for different ADCs, with ADC drivers and clock distribution circuits integrated on board. The Xilinx ZC706 FPGA development board is used as a DAQ board. The data from the ADC are routed to the FPGA through the FMC（FPGA Mezzanine Card）connector, de-serialized and monitored by the FPGA, and then transmitted to the host computer through the Gigabit Ethernet. A software program has been developed with Python, and all the commands are sent to the DAQ board through Gigabit Ethernet by this program. Two ADC boards have been designed for the ADC, ADS52J90 from Texas Instruments and AD9249 from Analog Devices respectively. TID tests for both ADCs have been performed at BNL, and an SEE test for the ADS52J90 has been performed at Massachusetts General Hospital（MGH）. Test results have been analyzed and presented. The test results demonstrate that this test system is very versatile, and works well for the radiation tolerance characterization of commercial multi-channel high-speed ADCs for the upgrade of the ATLAS LAr calorimeter. It is applicable to other collider physics experiments where radiation tolerance is required as well.

Nitrogen(N)and potassium(K)are the most required nutrients for corn and wheat *** the N application rate usually boosts crop ***,many uncertainties remain for K *** deficiency results in yield losses,but K application rate based on the percentage of K+in the cation exchange capacity(CEC)is doubtful,especially in soil with high CEC.A field trial was conducted to examine the effects of KCl application before sowing corn and wheat,by raising the percentage of K+in CEC at pH 7.0(CECpH7.0)to approximately 2.5%,3.5%,and 4.5%,and adding N as a topdressing(75,150,and 225 kg ha-1 to corn and 40,80,and 120 kg ha-1 to wheat)on the nutrition and yield of corn and wheat under a continuous no-till system(30 years).Exchangeable K+content increased in the topsoil(0–20 cm depth)up to 7.2 mmolc dm-3 after K application at the highest rate,which,however,did not result in significant increases in nutrient uptake and yields for both corn and *** N application rate positively affected the uptake and removal of all macronutrients by corn and *** N as a topdressing increased yields of corn and wheat by up to 83%and 22%,*** results suggest that in the soil with a high CECpH7.0(162.1 mmolc dm-3),the recommendation for K application made by considering the percentage of K+in the CECpH7.0 may result in excessive application of K fertilizer to crops with high K-recycling potential grown under a continuous no-till system.

Malpighian Tubules in Larvae of Diatraea saccharalis (Lepidoptera;Crambidae): A Morphological Comparison between Non-Parasitized and Parasitized by Cotesia flavipes (Hymenoptera;Braconidae)

In Diatraea saccharalis larvae, the Malpighian tubules are found along the digestive tube, extending from the middle mesenteric region to the end of the posterior intestine, where they come in contact with the rectum to form the cryptonephridium. Scanning and transmission electron microscopy of non-parasitized and parasitized larvae by Cotesia flavipes have indicated that the tubules consist of secretory and reabsorption cells. In parasitized larvae, the occurrence of hemocytes and teratocytes around the tubules is indicative of their role in immunological defense;however, they were not observed in non-parasitized larvae. At day 9 of parasitism, the mitochondria-containing vacuoles and myelin-like figures show signs of degeneration. The results of this study have confirmed that C. flavipes manipulates the physiology and biochemistry of D. saccharalis because the Malpighian tubules of the parasitized larvae remain active until the parasitoid completes its pupal stage and is released from the host organism.

Multidimensional Projections for Visual Analysis of Social Networks

Visual analysis of social networks is usually based on graph drawing algorithms and tools. However, social networks are a special kind of graph in the sense that interpretation of displayed relationships is heavily dependent on context. Context, in its turn, is given by attributes associated with graph elements, such as individual nodes, edges, and groups of edges, as well as by the nature of the connections between individuals. In most systems, attributes of individuals and communities are not taken into consideration during graph layout, except to derive weights for force-based placement strategies. This paper proposes a set of novel tools for displaying and exploring social networks based on attribute and connectivity mappings. These properties are employed to layout nodes on the plane via multidimensional projection techniques. For the attribute mapping, we show that node proximity in the layout corresponds to similarity in atgribute, leading to easiness in locating similar groups of nodes. The projection based on connectivity yields an initial placement that forgoes force-based or graph analysis algorithm, reaching a meaningful layout in one pass. When a force algorithm is then applied to this initial mapping, the final layout presents better properties than conventional force-based approaches. Numerical evaluations show a number of advantages of pre-mapping points via projections. User evaluation demonstrates that these tools promote ease of manipulation as well as fast identification of concepts and associations which cannot be easily expressed by conventional graph visualization alone. In order to allow better space usage for complex networks, a graph mapping on the surface of a sphere is also implemented.

Glutamine and glutamate supplementation raise milk glutamine concentrations in lactating gilts

Journal of Animal Science and Biotechnology 2012年第1期3卷 25-31页

Glutamine is the most abundant amino acid in milk, and lactation is associated with increased glutamine utilization both for milk synthesis and as a fuel for the enlarged small intestine. A number of recent studies have indicated that lactation is accompanied by a mild catabolic state in which skeletal muscle proteins are degraded to provide amino acids that are used to synthesize additional glutamine. In this study we tested the hypothesis that supplemental L-glutamine or the commercially available glutamine supplement Aminogut （2.5% by weight mixed into daily feed） provided to gilts from 30 days prior to parturition until 21 days post-parturition would prevent a decrease in skeletal muscle glutamine while increasing the glutamine content of the milk. Muscle glutamine content decreased （P 〈 0.05） in control animals during lactation but this was prevented by supplementation with either L-glutamine or Aminogut. In this study, neither lactation nor supplementation had any effect on plasma glutamine or glutamate content. Free glutamine, and the total glutamine plus glutamate concentrations in milk from the control and the Aminogut group rose （P 〈 0.05） during the first 7 days of lactation, with milk concentrations in the L-glutamine supplemented group showing a similar trend （P = 0.053）. Milk glutamate remained constant between day 7 and 21 of lactation in the control and L-glutamine supplemented groups, but by day 21 of lactation the free glutamine, glutamate, and glutamine plus glutamate concentrations in milk from Aminogut-treated gilts were higher than those of control gilts. Thus dietary glutamine supplementation can alleviate the fall in intramuscular glutamine content during lactation in gilts, and may alleviate some of the catabolic effects of lactation. Furthermore, the increased milk glutamine content in the supplemented gilts may provide optimum nutrition for piglet development.
