BACKGROUND Salvia africana-lutea L., an important medicinal sage used in the Western Cape (South Africa), can be termed a 'broad-spectrum remedy' suggesting the presence of a multiplicity of bioactive metabolites. This study aimed at assessing wild S. africana-lutea populations for chemotypic variation and anti-Fusarium properties. METHODS Samples were collected from four wild growing populat...

Captive and wild African elephants frequently suffer tusk fractures. Several institutions shorten the tusks of captive elephants to reduce fractures and injury as a result of behaviour within enclosures. Fracturing or coronal amputations that expose pulp lead to pain for the elephant. Estimating coronal pulp lengths may thus help to minimise the risk of pulp exposure during amputations. We aime...

The importance of assigning an accurate estimate of age and sex to elephant carcasses found in the wild has increased in recent years with the escalation in levels of poaching throughout Africa. Irregularities identified in current ageing techniques prompted the development of a new method to describe molar progression throughout life. Elephant mandibles (n = 323) were studied and a point near ...

BACKGROUND Inflammatory response in the CNS mediated by microglia cells play an important role in host defense and is implicated in the pathology of neurodegenerative diseases. We investigated the capacity of Entada africana to protect microglia from inflammatory insults by exploring the effect of the CH₂Cl₂/MEOH 5% fraction (Ea5) on pro-inflammatory cytokines mRNA expression. Finally, we studi...

RESUMO Raízes, sobrevivências, rotas, crioulização, rizoma e memória coletiva, todos esses motes são também metáforas analíticas historicamente mobilizadas para traduzir a identidade negra na(s) diáspora(s) afro-atlântica(s). Dito isso, o objetivo deste artigo é apresentar como diversas tradições de pensamento intelectuais antilhanos têm abordado tropo que delimita os estudos da diáspora africa...

Three new species of pterygosomatid mites Pterygosoma engai sp. nov. P. indare sp. nov. and P olape sp. nov. (Acari: Pterygosomatidae) are described from the agamid lizard Agama sankaranica (Sauria: Agamidae) from Kenya. P. engai sp. nov. is similar to P annectans circularis Jack, 1962 but in the new species, the anterior paddle-shaped setae with spicules on the apical margin of the idiosomal d...

Yawning is a widely recognized behavior in mammalian species. One would expect that elephants yawn, although to our knowledge, no one has reported observations of yawning in any species of elephant. After confirming a behavioral pattern matching the criteria of yawning in two Asian elephants (Elephas maximus) in a zoological setting, this study was pursued with nine captive African elephants (L...

INTRODUCTION The use of complementary and alternative medications has become a multi-million dollar business in the United States and comprises more than half of all filled prescriptions for benign prostatic hyperplasia (BPH) in Europe. For the practicing urologist, understanding the phytotherapeutic agents available, their proposed mechanism of action, the research supporting their use, and th...
