Background: The sustainability of animal production system depends mostly on feed management. Therefore, the combination of local leguminous forage as source of protein and ginger as phytobiotics can be one of the safe ways to attain this goal. The aim of this study was to evaluate the effect of ginger meal associated with ration containing local protein sources Desmodium intortum and/or Stylosanthes guianensis on growth performance in rabbits. Method: A total of 64 young rabbits (32 males and 32 females) with an average weight of 1000 ± 200 g were used. There were randomly assigned to 8 experimental diets in a complete randomized designed with 8 rabbits per treatment and each rabbit serving as an experimental unit. From the control diet R0 (basal diet without legumes and phytobiotic) and 7 other diets (treatment): R1(basal diet without legumes + 1% ginger powder), R2 (basal diet + 20% S. guianensis + 1% ginger meal), R3 (basal diet + 20% D. intortum + 1% ginger powder), R4 (basal diet + 20% D. intortum + 0% ginger powder), R5 (basal diet + 20% S. guianensis + 0% ginger powder), R6 (basal diet + 10% D. intortum + 10% S. guianensis + 0% ginger powder) R7 (basal diet + 10% D. intortum + 10% S. guianensis + 1% ginger powder). Feed intake, body weight gain, feed conversion ratio, carcass yield and average daily consumption were evaluated using standard procedures. Results: Feed intake and feed conversion ratio of animals fed R0 and R7 rations were significantly improved. Animals fed R1 ration had a significantly lower mean value for feed conversion ratio (1.83 g) and feed intake (1.67 g) respectively. Live weight (2432.54 g), total weight gain (1644.90 g), average daily feed intake (109.06 g) and dressed weight (1404.25 g) were significantly higher for rabbits fed R1 ration. Relative weights of organs of animals fed R4 ration were significantly higher. Conclusion: Feeding rabbits with R1 diet significantly improved growth performance.

Journal of Life Sciences 2013年第6期7卷 599-606页

Although microscopy still remains the gold standard for the diagnosis of malaria, rapid diagnostic tests （RDTs） and PCR assays have been shown to be sensitive and specific. Very few comparative studies have been reported of the three diagnostic methods on the same samples in vulnerable groups. Microscopy, RDTs and PCR assays were used for detection and speciation of Plasmodium falciparum （P）＇）, Plasmodium malariae （Pm） and Plasmodium ovale （Po） in patients in a rice culture savanna ecotype. Fifty four children and 16 pregnant women presenting with a fever were recruited. Bloods collected was used for thin and thick smears, perform RDTs and spotted blood on filter paper for DNA extraction and performance of a PCR. Mean parasitaemia was 37,619.06 （＋ 33,599.04） p/pL and 7,512.5 （＋ 12,446.11） p/μL for children and pregnant women, respectively. A total of 87.14% were positive by microscopy, 85.71% by RDTs and 90% by PCR. Distribution of Plasmodium species as identified by PCR was 72.86% Pf/Pm, 11.43% Pf/Pm/Po and 5.43% Pm while 10% were negative. Cohen＇s Kappa value for PCR and RDTs was K = 0.75 （CI = 0.28-1.22） while PCR and microscopy was K = 0.64 （CI = 0.18-1.10）. Malaria infection in Bangolan was mostly due to mix infection predominantly P. falciparum/P, malariae.

EAS将通过ATV交会预研(ARP)项目,验证欧洲实现在未来自动轨道转移飞行器(ATV)与国际阿尔法空间站(ISSA)自动交会对接所要掌握的关键技术。在该预研项目中,研制了一个基于GPS的相对导航系统(RGPS),作为远程接近操作(12km～300m)所采用的主要导航基准。其基本设计思想是利用卡尔曼滤波器处理两台GPS接收机在同一时刻接收到的数据,一个GPS接收机装在ATV上,另一个装在ISSA上。通过高逼真度的仿真试验证实了RGPS滤波器的性能和鲁棒性。在欧洲空间研究和技术中心(ESTEC)GPS试验室中进行了一系列开环测试(RGPS滤波器+真实ARP-GPS+NTC GPS仿真),更进一步验证了RGPS的设计思想。下一步的验证工作是处理在STS80/ASTRO-SPAS的交会操作期间由ARP-GPS所获取的数据。本文发表了在RGPS的研制和验证过程中所得到的令人满意的结果。

+-Evidence of Porphyry Deposits in the Ntem Complex: A Case Study from Structural and Hydrothermal Alteration Zones Mapping through Landsat-8 OLI, Aeromagnetic and Geological Data Integration in the Yaounde-Sangmelima Region (Southern Cameroon)

A semi-regional study was carried out in the Yaounde-Sangmelima area, a densely vegetated tropical region of southern Cameroon located in the Central Africa Fold Belt (CAFB)/Congo Craton (CC) transition zone. Towards structural lineaments and predictive hydrothermal porphyry deposits mapping, an integrated analysis of Landsat-8 OLI data, aeromagnetic, geological and mineral indices maps was performed. The Remote sensing using False colour composite images involving bands combinations and Crosta method (features oriented principal components analysis) enabled the mapping of the gneisses and schists domains without a clear differentiation between the Yaounde and Mbalmayo schists;despite the reflectance anomalies evidenced NW of Akonolinga, hydrothermal alterations in the study area failed to be detected. Besides, aeromagnetics depicted a moderately fractured northern zone (the CAFB) contrasting with a high densely fractured zone (the CC, known as Ntem complex). The Ntem complex displays signatures of a meta-igneous, an intrusive complex, greenstone relics south of Sangmelima and hydrothermal activity. Indeed, CET porphyry analysis tool detected many porphyry centres. In general, the study revealed many lineaments including contacts, fractures faults zones and strike-slips. The major aeromagnetics structures are SW-NE to WSW-ENE and WNW-ESE to NW-SE while those from Landsat-8 are NE-SW, WNW-ESE, NW-SE, WSW-ENE and NW-ESE to NNW-SSE. Together, these structures depict trans-compressions or trans-tensions corresponding to a broad NE-SW strike-slips channel that affect both the CAFB and the Ntem Complex, and they control the intrusions thus confirming a pervasive hydrothermal activity within the Ntem Complex. The proximity or coincidence of these porphyry centres with some mapped Iron-Gold affiliated mineral indices and porphyry granites indicate the possible occurrence of many hydrothermal ore deposits. These results show the high probability for the Ntem complex to host

AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic *** This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of *** Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction.
