The paper presents the analysis of Fula numeral system. Fula is an Atlantic language, dispersed throughout a vast territory in Sub-Saharan Africa. It has over 20 differently-sized lects subdivided into three zones - Western, Central and Eastern. The research included collecting the language data on six major lects, two from each zone. Then this data was analyzed from the point of view of internal and external syntax of ordinal, cardinal, distributive and fraction numerals. The comparative analysis of Fula numeral system on inter-lect scale has never been reflected in earlier Fula studies. Apart from a unique collection of numeral data from all language zones of Fula, the paper presents comparative analysis of such data, including, but not limited to, phonetic and contact-induced variabilities. The sources of structural and lexical loans in the system are listed wherever possible, because the disperse nature of Fula lects means that the contact languages and the ensuing changes can be different for each lect. Special attention is paid to the numeral bases, which can be somatic, commercial of a combination of the two. The Fula numeral system has never been analyzed from this point of view, and the contact changes to it are of great linguistic interest. Also cardinal numerals in Fula can change their form depending on the personality parameter of head noun. This system is unique for Fula and, more specifically, to its numeral system, and is properly described for the first time. Some parts of the Fula numeral system, like distributive and fraction numerals for some lects, have been found underrepresented and poorly described, which leaves room for further research, both field one and typological.

: Cissus aralioides is a medicinal plant used in sub-Saharan Africa for treatment of infectious diseases; however the chemical constituents of the plant have not been investigated. Thus, in this study, attempt was made at identifying predominant phytochemical constituents of the plant through chromatographic purification and silylation of the plant extract, and subsequent characterization using spectroscopic and GC-MS techniques. The minimum inhibitory concentration (MICs) for the antibacterial activities of the plant extract, chromatographic fractions and isolated compounds were also examined. Chromatographic purification of the ethyl acetate fraction from the whole plant afforded three compounds: β-sitosterol (1), stigmasterol (2) and friedelin (3). The phytosterols (1 and 2) were obtained together as a mixture. The GC-MS analysis of silylated extract indicated alcohols, fatty acids and sugars as predominant classes, with composition of 24.62, 36.90 and 26.52% respectively. Results of MICs indicated that friedelin and other chromatographic fractions had values (0.0626-1.0 mg/mL) comparable with the standard antibiotics used. Characterization of natural products from C. aralioides is being reported for the first time in this study.

AbstractPolystachya is a large, pantropical orchid genus of 200 species, most of which occur as epiphytes in sub-saharan Africa. The three-lobed labellum of most Polystachya species possesses a fleshy callus and various types of trichomes and papillae. In this paper, we present the results of micromorphological studies on the labellum of 20 species, representing eight of the 13 sections in the genus, using scanning electron microscopy (SEM). Our results show the scale of infrageneric diversity of trichomes and papillae relative to the sampled sections. They also demonstrate the taxonomic value of labellar micromorphology at the sectional level. The study revealed seven types of papillae and five types of trichomes (uni- and multi-cellular) in Polystachya, some of which, are described here for the first time. Clavate trichomes are the most common and are present in 60% of the species studied. Moniliform trichomes mainly occur in sect. Polystachya and are strongly characteristic of the section. Pseudopollen is formed by fragmentation of moniliform trichomes or the detachment of other trichomes as bicellular units. We provide, for the first time, evidence for the detachment of the terminal cells of capitate trichomes.

AbstractSchistosomiasis (bilharzia) is a neglected tropical disease caused by parasitic flatworms of the genus Schistosoma, with considerable morbidity in parts of the Middle East, South America, Southeast Asia, in sub-Saharan Africa, and particularly also in Europe. The WHO describes an increasing global health burden with more than 290 million people threatened by the disease and a potential to spread into regions with temperate climates like Corsica, France. The aim of our study was to investigate the influence of S. mansoni infection on colorectal carcinogenic signaling pathways in vivo and in vitro. S. mansoni infection, soluble egg antigens (SEA) and the Interleukin-4-inducing principle from S. mansoni eggs induce Wnt/β-catenin signaling and the protooncogene c-Jun as well as downstream factor Cyclin D1 and markers for DNA-damage, such as Parp1 and γH2a.x in enterocytes. The presence of these characteristic hallmarks of colorectal carcinogenesis was confirmed in colon biopsies from S. mansoni-infected patients demonstrating the clinical relevance of our findings. For the first time it was shown that S. mansoni SEA may be involved in the induction of colorectal carcinoma-associated signaling pathways.

Purpose Anecdotal accounts of suicide among temporary low-wage migrant workers in the UAE are numerous, but unofficial and qualitative accounts remain unexplored. This study aims to examine how the socio-environmental context can lead some low-wage migrants, irrespective of their nationality or culture, to contemplate suicide for the first time after arriving in the host country. Design/methodology/approach The findings draw from ten months of qualitative fieldwork (2015–2016) and in-depth interviews conducted with 44 temporary migrant workers from sub-Saharan Africa and South Asia, earning in the lowest wage bracket in Dubai. The study used a non-probabilistic, purposive sampling approach to select participants. Three criteria drove eligibility: participants had to reside in the UAE, be non-national and earn Dh1500 (US$408) or less a month. Otherwise, diversity was sought in regard to nationality, occupation and employer. Findings Eight (18%) of the 44 study participants interviewed admitted to engaging in suicidal thoughts for the first time after arriving in the UAE. The findings suggest that for low-wage migrants working in certain socio-environmental contexts, the religious, gendered or other cultural or group characteristics or patterns that may be predictors of suicide in migrants’ country of origin may become secondary or possibly even irrelevant when one is forced to survive under conditions that by most objective standards would be deemed not only oppressive but extremely exploitative and abusive. Originality/value This study contributes to understandings of how the emotional and psychological well-being of temporary foreign low-wage migrant workers can be impacted by the socio-environmental context of the host country. It is a first step in understanding the intimate thoughts of low-wage migrant workers on the topic of suicidality, furthering our understanding of suicidal ideation and the factors that can contribute to it.

Abstract Even so, no country in sub-Saharan Africa before 2000 had national control programs for any of the seven programs, with the exception of cervical cancer. Onchocerciasis is the target of the Africa Program for Onchocerciasis Control (APOC) with the help of many NGOs organisation using the drug mectizan (ivermectin). The use of drug financing at APOC is revolutionary. They had, for the first time, established as a viable concept with leprosy control programs, and now, with APOC, demonstrated that pharmaceutical companies can and will reuse a drug and treat it as part of a humanitarian response. This book chapter focused on repurposing drugs against schistosomiasis.

The Developed Countries

This chapter identifies four clusters of nations based on state of development, in order to highlight significant qualitative differences that may call for different law and policies. The first cluster comprises the least developed sub-Saharan African countries with the most resource-challenged competition authorities, such as Benin and Togo. The second cluster compromises nations that have advanced economically to a perceptibly higher level. The third cluster is a “group” of one—South Africa. With all of its challenges, the South African competition regime is as close to a gold standard as there is in sub-Saharan Africa. Finally, for comparison, the fourth cluster comprises the developed countries, led in particular by the European Union and the United States. These nations have open economies, fairly robust markets, good infrastructure, and good institutions. The chapter proceeds to identify, from the point of view of each of the clusters, the most fitting competition framework nationally and globally. The chapter proposes how the divergences can be brought into sympathy.

AbstractThis article adopts the theoretical framework of complex realism to trace the evolution of the Islamic Republic of Iran's foreign policy and developmental activities in Africa between the 1980s and the 2000s. Contrary to common assumptions, the deradicalization of the Islamic Republic's foreign policy in Africa began not under the moderates in the early 1990s, but under the conservatives in the mid-1980s. This period marked the first time that the Islamic Republic instrumentalized development to advance its strategic interests in Africa—a policy that has continued despite the factionalization of Iran's political elite. Based on one year of archival research and interviews in Iran, this article is the first to investigate the history and activities of the Islamic Republic's rural development organization, Construction Jihad, in Africa. It posits that development, instead of arms or ideology, has enabled Iran to make the farthest inroads into the continent due to Africa's sizeable agrarian economies, widespread rural poverty, and formidable developmental challenges.
