The genetic legacy of the Transatlantic Slave Trade in the island of New Providence

The Bahamian archipelago has been influenced by a wide array of settlers (Lucayans, Eleutherian Adventurers, British Loyalists, Creoles from the United States and African slaves) throughout its short but dynamic history. Nevertheless, the Bahamas remains poorly characterized genetically and little is known about each group's contribution to the island chain. In the current study, the population of New Providence was analyzed based on 15 autosomal STR loci routinely employed in forensic DNA fingerprinting applications. A comparison of this collection with African groups reveals similar genetic profiles to West African populations from Equatorial Guinea and Angola, possibly resulting from the importation of slaves from West African ports during the Transatlantic Slave Trade. Although the New Providence collection exhibits strong genetic affinities to the two US African American reference populations, the detection of unique alleles among them may necessitate the utilization of population-specific databases in forensic cases especially when the STR profiles include these specific variants.     

Food politics: perspectives on food security in Central Africa

Food security is political. The identification of food insecurity and the development and implementation of responses to it are enveloped in layers of politics and power. This politics might not be as readily apparent in emergency situations where broad agreement on the need for a response is evident. But in the everyday governance of food it must not be forgotten that food security is a contested concept. This article offers a preliminary elucidation of this politics in the Central African context. To do so it presents findings from an analysis of publicly available information and media reports. This analysis hones in on the perspectives of differently situated stakeholders on food security imperatives in the Central African Economic and Monetary Community. To identify similarities and differences in the levels of emphasis different stakeholders place on different aspects of food security, the authors employ Olivier De Schutter's understanding of the relevant dimensions. Specific terms used in the presentation of food security information are associated with one of the three dimensions of food security advanced by De Schutter: availability, accessibility and adequacy. In light of this analytic approach, the article finds that stakeholders – including businesses, civil society groups, governments and multilateral and bilateral partners – do not necessarily articulate similar viewpoints on food security. There is simply no unified view on what should be done to advance food security in Cameroon, Central African Republic, Chad, Congo-Brazzaville, Equatorial Guinea or Gabon. That being said, the article does identify intriguing areas of convergence.

Laboratory investigation of deaths due to anaphylaxis.

To establish a useful laboratory protocol to investigate possible cases of fatal anaphylaxis, we measured mast-cell-derived tryptase levels and allergen-specific immunoglobulin E (IgE) antibody levels in sera obtained prior to or within 24 h after death from 19 anaphylaxis victims. Elevated serum tryptase levels (range = 12 ng/mL to 150 micrograms/mL) were found in nine of nine Hymenoptera sting fatalities, six of eight food-induced fatalities, and two of two reactions to diagnostic therapeutic agents. Tryptase levels were normal (less than 10 ng/mL) in 57 sequential sera obtained postmortem from six control patients. Tryptase could not be measured in pleural or pericardial fluids for technical reasons. Serum IgE antibodies were elevated in five of the nine Hymenoptera sting fatalities and in eight of the eight fatal food reactions; assays were unavailable for the two diagnostic/therapeutic agents. If elevated, the victim's serum IgE antibodies to food could be used to identify allergens in uneaten portions of foods consumed shortly before the anaphylactic event. IgE antibodies were moderately stable during storage in a variety of anticoagulants at room temperature for up to 11 weeks. Elevated mast-cell-derived tryptase levels in postmortem sera reflect antemortem mast cell activation and may be used as a marker for fatal anaphylaxis. If assays are available for IgE antibodies to relevant allergens, such assays provide evidence for antemortem sensitization; these assays may be modified to identify allergens in foods consumed by victims of food-induced anaphylaxis.
