Introduction: The abdominal pregnancy is a rare pathology that can threaten the vital prognosis of the mother. The positive diagnosis is difficult to establish. It is most often made in an acute context, leading to a high fetomaternal morbidity and mortality. Our objective is to recall the diagnostic approach and optimal management of this condition. Case report: We present the case of an abdominal pregnancy at 18 weeks of amenorrhea with partial placental abruption in a 26-year-old patient who presented with abdominal pain in emergency obstetrical department of university hospital center of Agadir. The ultrasound revealed the presence of an evolving abdominal pregnancy. The MRI allowed precisely the localization of the placenta and its relationship with the surrounding organs. A laparotomy revealed the insertion of the placenta on the right adnexa. The right adnexectomy allowed removal of the placenta without incident. Conclusion: Abdominal pregnancy is difficult to diagnose. It is essential to be well informed about the clinical and ultrasonographic semiology of this pregnancy, in order to avoid operative surprises and to ensure the appropriate treatment.

在过去的几十年里,资本全球化,特别是外国直接投资(FDI)和贸易有了显著的增长。外国直接投资和贸易通常被视为发展中国家经济发展的关键催化剂。在发展中国家的经济发展过程中,外国直接投资是资本流动中最稳定和最大的组成部分。外国直接投资、贸易和东道国经济增长之间的关系是近年来经济学文献所研究的最为重要的问题之一。外国直接投资有助于提高东道国人力资本和机构的国内投资,是发达国家向发展中国家转让技术的重要手段。国际贸易也被认为是促进发展中国家经济增长的重要工具。本文在文献回顾之后,采用1998-2019年期间多变量框架下的年度时间系列数据,对FDI、贸易和经济增长之间的关系进行了实证研究。首先,研究分析了中国对外直接投资、进出口对巴基斯坦经济增长的影响。其次,探讨了中国外商直接投资对巴基斯坦国内投资产生挤入还是挤出效应。本文运用的研究方法包括时间系列技术,如增强迪基—富勒(ADF)和单位根测试,以检查变量的粘性;使用约翰森长期关系的联合集成测试,短期动力学的矢量误差校正模型(VECM),以及长期平衡的调整速度;使用技术脉冲响应功能(IRF)来调查系统内的相互关系。计量回归的估计结果表明,所有变量都是共同整合的。从长远来看,EXGS每增长1%,将促进巴基斯坦经济1.33个百分点的增长,中国对外直接投资每增长1%将产生巴基斯坦经济增长的幅度也超过百分之一。此外,与FDI相比,巴基斯坦国内投资每增长1%将导致巴基斯坦经济增长7.48%。冲动响应功能的结果表明,从长远来看,中国对外直接投资净额对巴基斯坦国内投资有积极影响。这意味着,中国对外直接投资对巴基斯坦国内投资的长期效应为挤入效应。这项研究为决策者制定有效的战略计划,欢迎中国对巴基斯坦的投资提供了未来的建议。

Pancreatic abscess typically occurs 4 weeks after acute pancreatitis begins and is defined as an infection of the pancreatic pseudocyst. There are other causes which include but are not limited to iatrogenic intra-abdominal procedures, chronic pancreatitis, and sending from distant sites. These abscesses are typically collections of pus that are within the region of the pancreas. There is also pancreatic necrosis that is seen among these abscesses. Here is a report on a case of a pancreatic abscess of unusual occurrence in a patient that had a near-total distal pancreatectomy. This is uncommon as the patient has very minimal pancreatic tissue remaining, yet still has developed this intra-abdominal abscess. These abscesses must be recognized quickly and removed to prevent further complications from occurring.

The patterning of neuronal cells and guiding neurite growth are important for neuron tissue engineering and cell-based biosensors. In this paper, inkjet printing has been employed to pattern self-assembled I3QGK peptide nanofibers on silk substrates for guiding the growth of neuron-like PC12 cells. Atomic force microscopy(AFM)confirmed the dynamic self-assembly of I3QGK into nanofiber structures. The printed self-assembled peptide strongly adheres to regenerated silk fibroin(RSF) substrates through charge-charge interactions. It was observed that in the absence of I3QGK, PC12 cells exhibited poor attachment to RSF films, while for RSF surfaces coated or printed with peptide nanofibers, cellular attachment was significantly improved in terms of both cell density and morphology. AFM results revealed that peptide nanofibers can promote the generation of axons and terminal buttons of PC12 cells, indicating that I3QGK nanofibers not only promote cellular attachment but also facilitate differentiation into neuronal phenotypes. Inkjet printing allows complex patterning of peptide nanofibers onto RSF substrates, which enabled us to engineer cell alignment and provide an opportunity to direct axonal development in vitro. The live/dead assay showed that printed I3QGK patterns exhibit no cytotoxicity to PC12 cells demonstrating potential for future nerve tissue engineering applications.
