Lung defence mechanisms against infection.
The respiratory tract must be open to the environment to allow exchange of gas between air and blood. This renders lhe lungs susceptible to colonization and infection by foreign organisms. It is necessary for lhe lower respiratory tract to have mechanisms to contain and control such foreign material. The gas exchange surface of lhe lung must be thin, delicate and permeable, rhus the mechanisms ...
متن کاملCooperative Defence Against DDoS Attacks
Distributed denial of service (DDoS) attacks on the Internet have become an immediate problem. As DDoS streams do not have common characteristics, currently available intrusion detection systems (IDS) cannot detect them accurately. As a result, defend DDoS attacks based on current available IDS will dramatically affect legitimate traffic. In this paper, we propose a distributed approach to defe...
متن کاملDefence against bacterial drug resistance.
How does resistance arise in bacteria ? One process is simply selection; treatment with an antibiotic eliminates sensitive strains and enables an originally very small minority of resistant ones to survive and spread. This is undoubtedly what happened among staphylococci in the early days of penicillin. When exposure to a drug-antibiotic or synthetic-is followed by resistance in a previously se...
متن کاملAutomated Radiological Monitoring at a Russian Ministry of Defence Naval Site
The Arctic Military Environmental Cooperation (AMEC) Program is a cooperative effort between the military establishments of the Kingdom of Norway, the Russian Federation, and the United States. This paper discusses joint activities conducted over the past year among Norwegian, Russian, and U.S. technical experts on a project to develop, demonstrate and implement automated radiological monitorin...
متن کاملEffector-triggered defence against apoplastic fungal pathogens
R gene-mediated host resistance against apoplastic fungal pathogens is not adequately explained by the terms pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) or effector-triggered immunity (ETI). Therefore, it is proposed that this type of resistance is termed 'effector-triggered defence' (ETD). Unlike PTI and ETI, ETD is mediated by R genes encoding cell surface-localised ...
