TL;DR: In this article, the authors present seven challenges for improving the confrontation of snakebite envenoming in Central America, which requires a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.
Abstract: Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally known as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.

Journal Article
TL;DR: It is concluded that the stingless bees had their center of origin and dispersion in Africa, based on the wide acceptance of continental drift, the primitiveness of several African Meliponinae, and the discovery of a European stingless bee fossil from the late Eocene, which shows that the Melip oninae were not restricted to America at that time.
Abstract: The present work attempts to establish probable evolutionary trends and relationships among the various groups of stingless bees, and in doing so to provide a new classification for the subfamily Meliponinae. This study concludes that the stingless bees had their center of origin and dispersion in Africa. This is based on the wide acceptance of continental drift, the primitiveness of several African Meliponinae, and the discovery of a European stingless bee fossil from the late Eocene, which shows that the Meliponinae were not restricted to America at that time.Parallel evolution seems to have taken place between the African genera and several groups of stingless bees from other continents. For instance, resemblances between Cleptotrigona and Lestrimelitta; between Dactylurina and Tetragona; between Meliponula and Melipona; and between Meliplebeia and Plebeia, result from parallelisms or convergences.The new classification here presented demostrates and defends the recognition of certain groups as genera and subgenera, and the relegation of other names to synonymy.

TL;DR: Shell morphological and strength measurements indicated that shell antipredator characteristics decreased in the order Thais > L. varia • L. fasciata, consistent with the hypothesis that predation is an important selective pressure influencing shell selection and utilization by C. panamensis.

TL;DR: The synthetic 13-mer p115-W3 constitutes the first example of a short, PLA(2)-based linear synthetic peptide with the ability to reproduce this effect of a parent protein in vivo, and is in clear support of the proposed relevance of the C-terminal region 115-129 in all the membrane-damaging mechanisms exerted by myotoxin II, including the myotoxic mechanism.

TL;DR: The high percentage of bats with neutralizing antibodies to dengue virus in these two Costa Rican communities suggests that bats may become infected with d Dengue virus, which appears to be the case in Costa Rica and Ecuador.
Abstract: Neutralizing antibodies for dengue virus serotypes 1 and 2 and serotypes 2 and 3 were detected in 1998 in 12 of 53 (22.6%) and 3 of 10 (30.0%) bats sampled in Costa Rica and Ecuador, respectively. Dengue is a consistent health problem in the two Costa Rican communities in which bats were sampled. The high percentage of bats with neutralizing antibodies to dengue virus in these two Costa Rican communities suggests that bats may become infected with dengue virus. This appears to be the case in Costa Rica and Ecuador.
