1. Mobilizing a pluralist theoretical approach to understand microlending digital platforms: the AfricaMC case
Abstract Purpose This study aims to explore how a microlending digital platform connects social investors in developed countries and micro-entrepreneurs in Africa. However, additional research is necessary to discuss how online auction models are designed and implemented and how existing theories can explain their use in the so-called developing countries.

2. ECONOMÍA Y ACTIVIDAD PESQUERA EN EL ATLÁNTICO SUR: EL CASO DE MOÇÂMEDES EN EL SIGLO XIX
Abstract This work analyzes Moçâmedes during the 19th century and its importance for the development of southern Angola and for trade with other ports in Africa and Portugal. It is observed that the main export goods were those derived from fishing in the cold waters of its coast and not those derived from agriculture, as it seemed to be the first intentio

3. Are regional differences in basketball already established in under-18 games?
Abstract Aims: To identify regional differences in basketball games for under-age categories, this study analyzed game-related statistics of four continental championships for under-18 (U18) men. Methods: A total of 149 games from each continental championship for U18 men held in 2016 were analyzed. A one-way analysis of variance followed by a Bonferroni

4. NS1 codon usage adaptation to humans in pandemic Zika virus
BACKGROUND Zika virus (ZIKV) was recognised as a zoonotic pathogen in Africa and southeastern Asia. Human infections were infrequently reported until 2007, when the first known epidemic occurred in Micronesia. After 2013, the Asian lineage of ZIKV spread along the Pacific Islands and Americas, causing severe outbreaks with millions of human infections. The

5. Toxicity and motor changes in Africanized honey bees (Apis mellifera L.) exposed to fipronil and imidacloprid
ABSTRACT This study evaluated the in vitro toxicity and motor activity changes in African-derived adult honey bees (Apis mellifera L.) exposed to lethal or sublethal doses of the insecticides fipronil and imidacloprid. Mortality of bees was assessed to determine the ingestion and contact lethal dose for 24 h using probit analysis. Motor activities in bees ex

6. Genetic diversity assessment in sorghum accessions using qualitative morphological and amplified fragment length polymorphism markers
Qualitative morphological and amplified fragment length polymorphism (AFLP) markers were compared for assessment of genetic diversity. Nine qualitative morphological traits were recorded to compare genetic relationships among 17 sorghum accessions with information derived from six AFLP primer combinations analysis. The mean morphological genetic similarity w

7. Public health aspects of snakebite care in West Africa: perspectives from Nigeria
Snakebite envenoming is a major public health problem among rural communities of the Nigerian savanna. The saw-scaled or carpet viper (Echis ocellatus) and, to a lesser extent, the African cobras (Naja spp.) and puff adders (Bitis arietans) have proved to be the most important cause of mortality and morbidity. The main clinical features of E. ocellatus enven

8. Inherited hemoglobin disorders in an Afro-Amazonian community: Saracura
The most common hemoglobinopathies, viz, hemoglobins S and C, and α-and β-thalassemias, were investigated through the molecular screening of 116 subjects from the community of Saracura, comprising fugitive African slaves from farms of the municipality of Santarém, in the west of Pará State, Brazilian Amazon. The observed frequency of the HBB*S gene (0.9%

9. Avaliação imunogenética dos genes dos receptores TOLL-LIKE 7, 8 e 9 em pacientes com lupus eritematoso sistêmico
O Lupus Eritematoso Sistêmico (LES) é uma doença crônica auto-imune caracterizada pela alta produção de auto-anticorpos contra antígenos nucleares e pela formação de imunocomplexos que desencadeiam resposta citotóxica. As causas do LES são desconhecidas, porém se têm alguns indícios bem descritos que alterações genéticas, imunológicas e/ou

10. β-globin haplotypes in normal and hemoglobinopathic individuals from Reconcavo Baiano, State of Bahia, Brazil
Five restriction site polymorphisms in the β-globin gene cluster (HincII-5'ε, HindIII-Gγ, HindIII-ªγ, HincII-'ψβ1 and HincII-3''ψβ1) were analyzed in three populations (n = 114) from Reconcavo Baiano, State of Bahia, Brazil. The groups included two urban populations from the towns of Cachoeira and Maragojipe and one rural Afro-descendant population,

11. Ribeiro's typology, genomes, and Spanish colonialism, as viewed from Gran Canaria and Colombia
Four biallelic and six multiallelic Y-chromosome polymorphisms were investigated in 59 Gran Canarian, 60 North African Berber and 46 Spanish subjects. These new data were merged with equivalent literature information to obtain the parental Y-chrosomomal contribution in Gran Canarians, Colombians, and Venezuelans. The results were then compared, for Gran Cana

12. Genetic structure of drone congregation areas of Africanized honeybees in southern Brazil
As yet, certain aspects of the Africanization process are not well understood, for example, the reproductive behavior of African and European honeybees and how the first Africanized swarms were formed and spread. Drone congregation areas (DCAs) are the ideal place to study honeybee reproduction under natural conditions since hundreds of drones from various c
