network BACKGROUND: Rickettsia raoultii is a novel Rickettsia species recently isolated from Dermacentor ticks and classified within the spotted fever group (SFG).The inability of R.raoultii to spread within L929 cells suggests that this bacterium is unable to polymerize host cell actin, a property exhibited by all SFG rickettsiae except R.peacocki
We present a holistic approach to the study of early archosauriform evolution by integrating body and track records.The ichnological record supports a Late Permian-Early Triassic radiation of archosauriforms not well documented by skeletal material, and new footprints from the Upper Permian of the southern Alps (Italy) provide evidence for a divers
Peripheral regulatory Protection Boots CD4+ T cells (Treg cells) prevent maladaptive inflammatory responses to innocuous foreign antigens.Treg cell dysfunction has been linked to many inflammatory diseases, including allergic airway inflammation.Glucocorticoids that are used to treat allergic airway inflammation and asthma are thought to work in pa
There is no global consensus on the use of prehospital triage systems in mass casualty incidents [1,2].However, most of the triage systems aim to cover four essential factors: speed, precision, fairness, and compatibility [3], of which the element of speed of decision-making is of importance, due to the large number of casualties that should be man
