mimic human disease as much as possible. in the past decades, the main effort has been focused on modelling of inhalational learn more anthrax and the perception of specific aspects of the infection has evolved in recent years. In this review, we consider criteria which can lead to the most appropriate choice of a given animal species for modelling human anthrax. We will highlight the positive input and limitations of different models and show that they are not mutually exclusive. On the contrary, their contribution to anthrax research can be more rewarding when taken in synergy. We will also present a reappraisal of inhalational anthrax and propose reflections on key points, such as portal of entry, connections between mediastinal lymph nodes, pleura and lymphatic drainage.

“P>Alternative splicing (AS) of precursor mRNAs is a widespread phenomenon in plants; however, many questions, GW4869 especially regarding its regulation and functional implications, remain to be elucidated. In vertebrates, polypyrimidine

tract-binding proteins (PTBs) have been identified as key splicing factors influencing splice site selection and orchestrating coordinated splicing programmes during developmental processes. Here, we analysed three PTB homologues from Arabidopsis thaliana and provide evidence for their gene regulatory potential based on AS and a splicing-independent mechanism. Our data reveal that Arabidopsis PTB homologues are subject to extensive auto- and cross-regulation via AS-coupled nonsense-mediated decay, thereby establishing a basis for interlinking their expression. Furthermore, the multiple modes of action of Arabidopsis PTB homologues are reflected in their subcellular localization in the nucleus, cytosol and processing bodies. This work provides insight

into the regulation of AS in plants and highlights the regulatory potential of the multifunctional plant PTB homologues, which might have important implications in diverse biological processes.”
“Anthrax is the archetype zoonosis; no other infectious disease affects such a wide range DMXAA molecular weight of species, including humans, although most susceptible are herbivorous mammals. Although the disease appears to have been recognized for centuries, it has yet to be established scientifically how animals contract it. While primarily a disease of warmer regions, it has long been spread to cooler zones through the trade of infected animals or contaminated animal products. Today it is still endemic in many countries of Africa and Asia and non-endemic countries must remain alert to the possibility of imports from such endemic areas resulting in outbreaks in their own livestock.
