Livestock is traditionally managed in mixed crop-livestock production systems in sud-Kivu, D. R. Congo. Currently, livestock production is facing numerous constraints due to wars and insecurity in the country, with looting of animals, demographic pressure on natural resources, and lack of extension services. multipurpose trees and shrubs with adequate forage quality could help overcome dry-season feed shortage. The objective of this research was to assess the agro-ecological adaptability of selected forage tree and shrub legumes combined with farmer participatory evaluation. The study was carried out at two distinct mid-altitude sites in sud-Kivu. Trees and shrubs were planted randomly in eleven lines, with each species/accession consisting of nine plants split into three replications. Following a standardization cut after one year of growth, regular biomass harvests were performed every eight weeks during one year;Desmodium and Flemingia were cut at 0.5 m above soil surface, while Leucaena and Calliandra.at 1 m. Before every harvest, plant height was measured and number of stems counted. Fresh leaf and stem biomass were weighted, sub samples dried and leaves analyzed for nutritive value. Results from agronomic evaluation show that Leucaena diversifolia ILRI 15551 and Leucaena leucocephala had the highest yield in the rainy season on fertile soil;during dry season, Leucaena diversifolia ILRI 15551 was superior. On poor soil, Flemingia macrophylla CIAT 17403 performed best in both seasons, however, its forage quality was relatively low. Forage tree and shrub legumes chosen by farmers were, in general, the same as those superior ones in agronomic evaluation.

A model is constructed to study the statistical properties of irregular trajectories of a log-gas whose positions are those of the complex eigenvalues of the unitary Ginibre ensemble. It is shown that statistically the trajectories form a structure that reveals the eigenvalue departure positions. It is also shown that the curvatures of the ensemble of trajectories are Cauchy distributed.

Synofit Premium in Refractory Low Back Pain: A Retrospective Observational Study

引用

Open Journal of Rheumatology and Autoimmune Diseases 2017年第2期7卷 120-127页

作者： Jiangan Qu Christian mélot Thierry Appelboom Dept. of Rheumatology and Physical medicine Iris Sud Hospital Brussels Belgium Dept. of Emergency Erasme University Hospital Brussels Belgium

In this retrospective observational study, information about pain and quality of life was collected for analysis from medical records of 85 patients with chronic low back pain who were treated for 3 months with Synofit? Premium (2 - 3 capsules daily), a liquid mixture of green-lipped mussel from New Zealand, blackcurrant leaf, and curcuma extract. Within the first 6 weeks of therapy, a significant clinical benefit was observed for relief from pain, need for pain-relieving drugs, and the interference of pain with personal care and lifting. This benefit was more pronounced at 3 months. The mixture was well tolerated without significant side effects. Adherence was estimated to be “good” to “very good.” Patients assessed global improvement and efficacy as “sufficient” to “good.” Based on this study, the mode of action of Synofit? Premium appears mainly to be analgesic, as reported by patients, and allows them to reduce the consumption of other pain-relieving substances and improve their quality of life. In conclusion, Synofit? Premium holds potential as a promising candidate alternative therapy for relief of low back pain and likely other painful rheumatic conditions, with almost no or minor side effects.

Genetic comparison between Rhynchophorus ferrugineus （Coleoptera： Curculionidae： Rhynchophorinae） and other four Rhynchophorus spp. such as R. bilineatus, R. phoenicis, R. cruentatus and R. palmarum was investigated using partial sequences of Cytochrome c oxidase subunit I （COl） mitochondrial gene. The number ofpolymorphic sites ranged from 79 to 102 while the genetic distances ranged from 0.058 to 0.095. The number of polymorphic sites, genetic distances and phylogenetic relationships among R. ferrugineus and the other four tested species revealed that *** was more closely related to R. bilineatus while it was distantly related to R. palmarum. It is possible to rank the five tested species as follows： ***, R. bilineatus, R. phoenicis, R. cruentatus and R. palmarum. The result of this study is the first step of the revision of the uncertain taxonomic status and phylogenetic relationships among the Rhynchophorus genus. Further analysis should be performed using other Rhynchophorus species as well as other molecular markers.

AIm： Anti-Saccharomyces anti-nuclear associated cerevisiae antibodies （ASCA）, anti-neutrophil antibodies （NANA） and antibodies to exocrine pancreas （PAB）, are serological tools for discriminating Crohn＇s disease （CrD） and ulcerative colitis （UC）. Like CrD, coeliac disease （COD） is an inflammatory bowel disease （IBD） associated with （auto） antibodies. Performing a multicenter study we primarily aimed to determine the performance of ASCA, NANA and PAB tests for IBD diagnosis in children and adults, and secondarily to evaluate the prevalence of these markers in CoD. mETHODS： Sera of 109 patients with CrD, 78 with UC, 45 with CoD and 50 healthy blood donors were retrospectively included. ASCA, NANA and PAB were detected by indirect immunofluorescence （IIF）. RESULTS： ASCA＋/NANA- profile displayed a positive predictive value of 94.2% for CrD. Detection of ASCA was correlated with a more severe clinical profile of CrD and treatment of the disease did not influence their serum levels. ASCA positivity was found in 37.9% of active *** were found in 36.7% CrD and 13.3% CoD patients and were not correlated with clinical features of CrD, except with an early onset of the disease. Fifteen CrD patients were ASCA negative and PAB positive. CONCLUSION： ASCA and PAB detected by IIF are specific markers for CrD although their presence does not rule out a possible active CoD. The combination of ASCA, NANA and PAB tests improves the sensitivity of immunological markers for CrD. Repeating ASCA, NANA, and PAB testing during the course of CrD has no clinical value.
