Objective: To compile available data and to estimate the burden, characteristics and risks factors of cutaneous leishmaniasis(CL) in Mali. Methods: Articles in English and French were searched in Hinari, Google scholar and PubM ed. Unpublished studies were identified by searching in ***. Terms used were Cutaneous leishmaniasis Mali; Leishmaniasis Mali, Leishmania major Mali; or Phlebotomus Mali or Sergentomyia Mali. We select descriptive studies on CL and sandflies in Mali. Data were extracted and checked by the author, then analyzed by region, by study population and type of biological tests, meta-analysis approach with STATA software was used. Results: Nineteen published(n=19) and three unpublished were included. CL epidemiology was characterized by occurrence of clinical cases in different areas of Mali, outbreaks restricted to known areas of transmission and isolated cases diagnosed in travelers. In endemic areas, population at risk are young age persons, farmers, ranchers, housewives, teachers and military personnel. The annual incidence ranged from 290 to 580 cases of CL. Leishmania major is the main species encountered throughout the country(North Savanna, Sahel and Sub-Saharan areas), and Phlebotomus duboscqi has been identified as the vector and Sergentomyia(Spelaeomyia)darlingi as possible vector. The overall estimated prevalence of positive LST(Leishmanin Skin Test) was 22.1%. The overall frequency of CL disease among suspected cases was 40.3%. Conclusions: Although descriptive, hospital-based and cross-sectional studies are robust enough to determine the extent of CL in Mali; future well-designed eco-epidemiological studies at a nationwide scale are needed to fully characterize CL epidemiology and risk factors in Mali.

掌握流体在多孔介质中得流动规律是油藏工程领域得一个基本问题。对油藏中压力分布以及流量随时间的变化进行仔细分析和模拟能够帮我工程人员了解流体在多孔介质中得输运动态。单相渗流模型是描述多孔介质渗流过程最简单的模型,虽然理论上较为简单,该类模型常用于油气田开发早期的流动模拟计算或简化的流动分析场合。本文介绍了课题组内的2维单相渗流数值模拟器的基本原理并编程实现了计算过程。渗流方程组采用有限差分法离散,并采用Stone提出的强隐式解法求解渗流方程。数值模拟器采用MATLAB编程实现,其计算可应用与可压缩流和微可压缩流。为了验证计算结果的正确性,分别验证了时间步长内的物料守恒和累计物料守恒,显示了计算结果的正确性。

Humeral Metastasis of Renal Clear Cell Carcinoma, a Case Report and Review of the Literature

Open Journal of Orthopedics 2023年第7期13卷 275-281页

作者： Mohamed Idrissa Seidou Issa Soumana Yahaya ali Moussa Niandou mahamadou Dalatou Malam Maman Abassa Seyni Zirbine Seyni Souna Badio Traumatology and Orthopedics Department of Amirou Boubacar Diallo National Hospital Niamey Niger Faculty of Health Sciences Abdou Moumouni University of Niamey Niamey Niger

Introduction: Adult bone tumors may be primary or secondary. Their diagnosis is often based on the results of imaging tests but can also be completed by biopsy. Case Presentation: We report the observation of a clinical case of fortuitous discovery in the orthopaedic-traumatology department of the national hospital Amirou Boubacar Diallo of Niamey, pathological fracture of the right humeral shaft secondary to metastasis of clear-cell adenocarcinoma of renal origin, a 57-year-old man, a refrigeration engineer by profession, from Niger living in the Middle East. This patient has no known pathological history. He consulted us for pain in his right arm that was more severe at night. All imaging and pathology examinations carried out both in Niger and in the Middle East confirmed the diagnosis of humeral metastasis of clear-cell renal cell carcinoma. Surgical management consisted of tumor resection and Kuntscher-type centromedullary alignment nailing of the fracture site. The loss of bone substance in the fracture is filled with acrylic cement. The treatment was completed by chemotherapy. Conclusion: Bone tumours are most often secondary in location. However, the diagnosis must be sought in the presence of any clinical sign.

align:justify;"> Striga species affect the potential productivity of cereals in sub-Saharian Africa due to the lack of durable Striga-resistance in host crops. This study aimed at inducing the new source of resistance in sorghum using gamma irradiation. Dry seeds of three Sorghum varieties;Grinkan, ICV1049 and Sariaso14 were gamma-irradiated with 200 Gy, 300 Gy, 400 Gy and 500 Gy. Screening strategies involved a 2-year field and greenhouse experiments, where mutant Sorghum families, their parents and resistant control were artificially infected with Striga hermonthica seeds. Field screenings revealed induced genetic variability among them, forty families significantly reduced the number of emerged Striga plants or showed good Sorghum grain yield performance despite the infection by S. hermonthica ecotype from Burkina Faso. The induced putative resistant mutants were identified across the four applied gamma-irradiation doses. Greenhouse experiment confirmed Striga resistance in seven mutant Sorghum families leading to no emergence of Burkina’s S. hermonthica ecotype along with high resistance index (RI) and low Striga damage score. Among them, two mutants SA38M5 and IC47M5 withstood S. hermonthica
