The classical period in Mexico (AD 250-750) was an era of splendor. The city of Teotihuacan was one of the largest and most sophisticated human conglomerates of the pre-industrial world. The Mayan civilization in southeastern Mexico and the Yucatan peninsula reached an impressive degree of development at the same time. This time of prosperity came to an end during the Terminal Classic Period (A...

In the 40 years since the recognition of filoviruses as agents of lethal human disease, there have been no specific advances in antiviral therapies or vaccines and few clinical studies on the efficacy of supportive care. On 20 September 2006, experts from 14 countries representing 68 institutions integrally involved in the response to outbreaks of filovirus hemorrhagic fever gathered at the Nat...

BACKGROUND Since the year 2000, Uganda has experienced repeated outbreaks of viral hemorrhagic fevers (VHF). Ebola VHF outbreak occurred in the districts of Gulu in 2000, Bundibugyo, 2007, Luwero, 2011, Kibaale in July 2012, Luwero in November 2012. Marburg VHF was earlier reported in Ibanda in 2007. More recently in 2012, two outbreaks of Marburg VHF have occurred in Ibanda and Kabale district...

Viral hemorrhagic fevers (VHF) are acute zoonotic diseases that, early on, seem to cause platelet destruction or dysfunction. Here we present the four major ways viruses affect platelet development and function and new evidence of molecular factors that are preferentially induced by the more pathogenic members of the families Flaviviridae, Bunyaviridae, Arenaviridae, and Filoviridae. A systemat...

The native population collapse in 16th century Mexico was a demographic catastrophe with one of the highest death rates in history. Recently developed tree-ring evidence has allowed the levels of precipitation to be reconstructed for north central Mexico, adding to the growing body of epidemiologic evidence and indicating that the 1545 and 1576 epidemics of cocoliztli (Nahuatl for "pest") were ...

Ebola virus is responsible for causing severe hemorrhagic fevers, with case fatality rates of up to 90%. Currently, no antiviral or vaccine is licensed against Ebola virus. A phosphatidylserine-targeting antibody (PGN401, bavituximab) has previously been shown to have broad-spectrum antiviral activity. Here, we demonstrate that PGN401 specifically binds to Ebola virus and recognizes infected ce...

Summary High-throughput screening of the host transcriptional response to various viral infections provides a wealth of data but utilization of microarray and next generation sequencing (NGS) data for analysis can be difficult. The Host Transcriptional Response DataBase (HoTResDB), allows visitors to access already processed microarray and NGS data from non-human primate models of viral hemorrh...
