flaviviridae are viruses that cause several diseases including dengue fever, japanese encephalitis, murray valley encephalitis, tick-borne encephalitis, west nile encephalitis, yellow fever and hepatitis c virus infection. members of this family have monopartite, linear, single-stranded rna genomes of positive polarity, 9.6-12.3 kb in length. here, we have analyzed the codon usage of 13 species...
The first category includes endemic African diseases which have evolved with and cycle in the various indigenous wildlife populations which, in turn, act as sylvatic reservoirs of the infectious agents. These diseases usually cause only minimal debility or mortality in indigenous wildlife and the infections are often subclinical. In contrast, infection of domestic livestock with these agents us...
Recently, Dario Fiore and Rosario Gennaro proposed the IB-KA protocol, which was inspired by MQV protocol. They provide a full proof of security of IB-KA protocol using techniques developed by Krawczyk in the Canetti-Krawczyk model. They designed the IB-KA protocol with some security properties such as perfect forward secrecy, reflection attack resilience, and key compromise impersonation resil...
The public debate on health risks has strongly increased in Germany in recent years. One reason for this increase may be the often dramatic manner of news reporting in the media that informs the public on current outbreaks of BSE, bird flu or Ebola. Afterwards, it often became apparent that the sometimes fierce discussions had not addressed the core of the problem at all, and the public was lef...
Fourier transform infrared (FT-IR) spectra have been measured for defatted bovine serum albumin (BSA) in D(2)O with a concentration of 2.0 wt % over a temperature range of 26-90 degrees C and the corresponding difference spectra have been calculated by subtracting the contribution of D(2)O at the same temperature. Evolving factor analysis (EFA) by selecting two factors and three factors has bee...
There are severe cattle-specific viral (foot and mouth, vesicular stomatitis, rinderpest, rift valley fever, malignant catarrhal lumpy skin, rabies, bovine leukosis, diarrhea, spongiform encephalopathy), bacterial (tuberculosis, black quarter, botulism, oedema, leptospirosis, brucellosis, anthrax, hemogenic septicemia, actinomycosis, actinobacillosis, mastitis, metritis), parasitic (lungworm, f...
East Coast fever is a lymphoproliferative disease caused by the tick-borne protozoan parasite Theileria parva. The sporozoite stage of this parasite, harboured and released from the salivary glands of the tick Rhipicephalus appendiculatus during feeding, invades and establishes infection in bovine lymphocytes. Blocking this initial stage of invasion presents a promising vaccine strategy for con...
In drylands, both dust storms and ephemeral salt lakes (playas) are common. Observations using remote sensing and ground studies have shown that these playas can be major sources of saline dust storms. Some basins have recently become desiccated as a result of water abstraction by humans, and these have become significant sources of dust. The timing and amounts of dust emissions depends on such...
