The world continues to battle the ongoing COVID-19 pandemic. Whereas many countries are currently experiencing the second wave of the outbreak; Africa, despite being the last continent to be affected by the virus, has not experienced as much devastation as other continents. For example, West Africa, with a population of 367 million people, had confirmed 412 178 cases of COVID-19 with 5363 deaths as of 14 March 2021; compared with the USA which had recorded almost 30 million cases and 530 000 deaths, despite having a slightly smaller population (328 million). Several postulations have been made in an attempt to explain this phenomenon. One hypothesis is that African countries have leveraged on experiences from past epidemics to build resilience and response strategies which may be contributing to protecting the continent’s health systems from being overwhelmed. This practice paper from the West African Health Organization presents experience and data from the field on how countries in the region mobilised support to address the pandemic in the first year, leveraging on systems, infrastructure, capacities developed and experiences from the 2014 Ebola virus disease outbreak.

In 2013, the Institute for African Studies of the Russian Academy of Sciences began a study of black communities in the USA. By now, the research was conducted in six states (Alabama, Illinois, Massachusetts, Minnesota, New York and Pennsylvania); in a number of towns as well as in the cities of Boston, Minneapolis, New York, Philadelphia and Chicago. The study shows that diasporas as network communities have already formed among recent migrants from many African countries in the U.S. These are diasporas of immigrants from individual countries, not a single “African diaspora”. On one hand, diasporas as an important phenomenon of globalization should become objects of global governance by means of regulation at the transnational level of both migration streams and foreign-born communities norms of existence. On the other hand, diasporas can be agents of social and political global governance, of essentially transnational impact on particular societies and states sending and accepting migrants, as evidenced by the African diasporas in the USA. Most American Africans believe that diasporas must and can take an active part in the home countries’ public life. However, the majority of them concentrates on targeted assistance to certain people – their loved ones back home. The forms of this assistance are diverse, but the main of them is sending remittances. At the same time, the money received from migrants by specific people makes an impact on the whole society and state. For many African states these remittances form a significant part of national income. The migrants’ remittances allow the states to lower the level of social tension. Simultaneously, they have to be especially thorough while building relationships with the migrant accepting countries and with diasporas themselves. Africans constitute an absolute minority among recent migrants in the USA. Nevertheless, directly or indirectly, they exert a certain influence on the establishment of the social life principles and state politics (home and foreign), not only of native countries but also of the accepting one, the U.S. This props up the argument that elaboration of norms and setting the rules of global governance is a business of not only political actors, but of the globalizing civil society, its institutions and organizations either. The most recent example are public debates in the American establishment, including President Obama, on the problem of immigration policy and relationships with migrant sending states, provoked by the 2014 U.S.–Africa Leaders Summit. Remarkably, the African diasporas represented by their leaders actively joined the discussion and openly declared that the state pays insufficiently little attention to the migrants’ needs and insisted on taking their position into account while planning immigration reform. However, Africans are becoming less and less “invisible” in the American society not only in connection with loud, but infrequent specific events. Many educated Africans who have managed to achieve a decent social status and financial position for themselves, have a desire not just to promote the adaptation of migrants from Africa, but to make their collective voice heard in American society and the state at the local and national levels. Their efforts take different forms, but most often they result in establishing and running of various diaspora organizations. These associations become new cells of the American civil society, and in this capacity affect the society itself and the government institutions best they can. Thus, the evidence on Africans in the USA shows that diasporas are both objects (to date, mainly potential) and real subjects of global governance. They influence public life, home and foreign policy of the migrant sending African countries and of migrant accepting United States, make a modest but undeniable contribution to the global phenomena and processes management principles and mechanisms.

The vegetable Momordica charantia L., (family: Cucurbitaceae) is a scientific name of the plant and its fruit. It is also known by other names, for instance in the USA it is known as Bitter gourd or balsam pear while it’s referred to as the African cucumber in many African countries. M. charantia is believed to posse’s anti-carcinogenic properties and it can modulate its effect via xenobiotic metabolism and oxidative stress. This study was specifically designed to investigate the cellular mechanisms whereby α, β momorcharin an extract of M. charantia can induce cell death with the combination of Cyclophosphamide. Different concentration (200µM - 1000µM) of the α, β momorcharin fruit extract were treated (24 hrs incubation) separately with three different cancer cell lines 1321N1, Gos-3, U87-MG and normal L6 muscle cell line. The results also show that Cyclophosphamide (250 µg) with (1000 µM) of the α, β momorcharin extract of M. charantia, and result in significant decreases in cell viability for each cell line, these effects were additive compared to the individual effect of Cyclophosphamide.

Abstract Background: The achievements in Ebola virus disease (EVD) prevention and control can be reflected by scientific studies, particularly in the top-cited studies. The study thus aimed to identify and characterise the 100 top-cited studies of Ebola.Methods: The study used a retrospective bibliometric analysis, which was performed in January 2020. Studies were searched from the Web of Science using the keywords: “Ebola” or “Ebola virus” or “Ebola virus disease” to identify the 100 top-cited ebola studies. Studies were analysed for the number of citations, authorship, and journal, year of publication, country and institution. The analyses were carried out using SPSS, HistCite and VOSviewer.Results: The 100 top-cited studies were published between 1977 and 2017, were cited from 169 to 808 times and had an average citation of 290.5, and 8 studies were cited more than 500 times. They were published in 31 journals, and Journal of Virology published most of the studies (n=14). They were produced by 33 countries, and the USA published most of the studies (63), followed by Germany (8) and Gabon (6). Centre for Disease prevention and Control-USA (26) was the leading institution, while Geisbert TW and Sanchez A were the most productive authors.Conclusions: This study provides insights into the historical advancements reflected by the top-cited studies and has highlighted the leading roles played by various stakeholders in addressing EVD. However, the contribution of African countries is not sufficiently reflected among these studies, and so more focus, funding and involvement in clinical research is needed for effective prevention and control of EVD in Africa.

On May 4, 2021, an international scientific and practical conference Preservation of the cultural heritage of Russia was held in Surgut. Masters and young scientists from Russia, the USA, Northern Ireland, Spain, Italy, Estonia and Moldova took part in the conference to gain new experience and share findings of their research on the topic. The main theme stated in the name of the conference determined its theoretical and practical focus. The conference comprised two major sections — Topical issues of preserving Russian culture and Implementation of projects for the preservation of Russian cultural heritage in Russia and abroad. N. K. Murnova opened the plenary meeting with a talk about Doctor of History Tatiana Vyacheslavovna Tobolina and her contribution to the study of Russian emigration of the 20th century. Orthodox Archpriest G. A. Zavershinskiy presented his books on history and religion. One of the key ideas of his report is that the common dichotomy of East and West is no longer viable and should be rejected in favor of antinomy and analogy of cognition. K. A. Frolova representing the Department of international relations of the Orthodox Church spoke about the problem of anti-Russia prejudice and integrity of Russian culture. Delegates representing MGIMO University (Moscow, Russia) presented their reports on periodicals published by Russian emigrants, identity as a general phenomenon, local museums preserving memories of unique events in regional history. Doctor of Philosophy V. S. Glagolev turned to the dimentiality of seeing beauty depending on historical and cultural peculiarities. N. L. Krylov from the Institute of Africa of the Russian Academy of Science devoted his report to the role of women in the conservation of Russian language and traditions in Northern African countries: Russian-speaking women living in Africa manage to assimilate in their countries of residence and nevertheless preserve their Russian identity. Moreover, they take an active part in social and religious local organizations. The conference gave a platform for many other exciting reports on tourism, museology, religious art and education. It was a special joy to hear a talk by T. D. Dzenlyuk, a fourth-generation Russian emigrant, about the work of an Orthodox church in Miami, USA, and the lifestyle of Russian emigrants there. The conference was rich in fascinating reports on diverse topics and ended with a folk concert.

As a self-proclaimed “Global Leader” the United States have made “the assertion, advancement, support and defense of democracy” throughout the world one of the pillars of their foreign policy. This aim invariably figures in all Washington’s program documents pertaining to Africa. A major component of these efforts is an assistance to regular, free and fair elections. The selection of arguments cited to justify such activities has been done skilfully. In each specific case it is emphasized that the United States do not side with any competing party, stand “above the battle”, work for the perfection of electoral process, defend the rights of opposition and rank and file votes, render material and technical help to national electoral committees. Sounds irreproachable. However, the real situation is different. The study of the US practical activities in this field allows to conclude that Washington has one-sidedly awarded itself a role of a judge and supervisor of developments related to elections in the sovereign countries of Africa, tries to control the ways they are prepared and conducted. These activities signify an interference into the internal affairs of African states. The scale and forms of such interference differ and is subjected to tasks the USA try to resolve in this or that country on the national, regional or global levels. However, everywhere it serves as an instrument of penetration and strengthening of the US influence, enhancing the US political presence in African countries. The right of the US to perform this role is presented as indisputable. Sceptics are branded as opponents of democracy. The author explores the US positions and activities connected with elections in Africa during the last years of B.Obama and first two years of D.Trump presidencies. He shows how their policy have been implemented on the continental level and in regard to several countries – South Sudan, Libya, Democratic Republic of Congo, Burundi, Rwanda, Nigeria, Somali, Kenya, Uganda.


As Chinese and African countries grow in trade and economic development so has the soft power dynamics. Healthcare has been an area where the Chinese have dominated the area for the last decade. The USA has been in a decline and has been absent in providing the leadership in healthcare soft power dynamics. The partisan politics in the USA has consumed the United States Agency for International Development bringing an era of Chinese experimentation with a free market (capitalism) and toying with international development superpower status. Yet, there are still areas of improvement for healthcare in Africa between United States America (USA) and China (PRC). Africans have become used to engaging with the Chinese in the hope of meeting their developmental healthcare goals. But the acceptance of the Chinese healthcare and medicine in Africa is a game changer in the healthcare diplomacy arena.

Through individual and group testimonies from newly arrived, 1.5 and second generation sub-Saharan Africans (For this study sub-Saharan African refers to the countries located under Northern African countries, for example, Egypt and Morocco and, includes South Africa. There are over 50 countries represented by this region; however, the most populous groups from this region in Africa in the USA are Nigerian, Ethiopian, Kenyan, Liberian, Ghanaian, Cape Verdean, South African, and Somalian.), the diversity and complexity linked to their migration and integration experiences in the USA reveal that there is a gendered and generational element to their self identity. These elements are compounded by perceptions of being African American in a racialized society and deciding whether or not to stay connected to Africa, a continent that needs their financial, political, and social resources accumulated in the USA These “new” African Americans expand the definition of blackness in the USA. Many have created a transnational relationship to Africa and the USA, which provides important implications for Africa’s potential “brain gain” as well as socioeconomic, infrastructural, and political development.

The focus of the review paper is to discuss how biotechnological innovations are opening new frontiers to mitigate nutrition in key agricultural crops with potential for large-scale health impact to people in Africa. The general objective of the Africa Biofortified Sorghum (ABS) project is to develop and deploy sorghum with enhanced pro-vitamin A to farmers and end-users in Africa to alleviate vitamin A-related micronutrient deficiency diseases. To achieve this objective the project technology development team has developed several promising high pro-vitamin A sorghum events. ABS 203 events are so far the most advanced and well-characterised lead events with about 12 μg β-carotene/g tissue which would supply about 40–50 % of the daily recommended vitamin A at harvest. Through gene expression optimisation other events with higher amounts of pro-vitamin A, including ABS 214, ABS 235, ABS 239 with 25, 30–40, 40–50 μg β-carotene/g tissue, respectively, have been developed. ABS 239 would provide twice recommended pro-vitamin A at harvest, 50–90 % after 3 months storage and 13–45 % after 6 months storage for children. Preliminary results of introgression of ABS pro-vitamin A traits into local sorghum varieties in target countries Nigeria and Kenya show stable introgression of ABS vitamin A into local farmer-preferred sorghums varieties. ABS gene Intellectual Property Rights and Freedom to Operate have been donated for use royalty free for Africa. Prior to the focus on the current target countries, the project was implemented by fourteen institutions in Africa and the USA. For the next 5 years, the project will complete ABS product development, complete regulatory science data package and apply for product deregulation in target African countries.
