The complement system was discovered a century ago as a potent defense cascade of innate immunity. After its first description, continuous experimental and clinical research has been performed and three canonical pathways of activation were established. Upon activation by traumatic or surgical tissue damage, complement reveals beneficial functions of pathogen and danger defense by sensing and c...

This report presents a prototype architecture for an active defense mechanism for computer systems. The intrusion detection problem is introduced and some of the key aspects of any solution are explained. Previous attempts to use similar techniques are discussed, and their shortcomings are explained. A new architecture is proposed which uses Genetic Programming to evolve programs to detect anom...

We established a new plant defense response assay using a transient expression system in rice protoplasts. The assay system sensitively detected defense induction by flagellin, which had previously been assigned to a specific elicitor. Our assay system provides a rapid and efficient way to dissect rice defense mechanisms.

background: oxidative stress is described as the formation of toxic effect due to the deficiency of cellular antioxidative level toward the level of reactive oxygen species (ros). the excess production of ros or the decrease in the antioxidative defense system could be the cause for oxidative stress. 7,12-dimethylbenz[a]anthracene (dmba) that is known to be the major cause the increment in lipi...

the role of the antioxidant defense system was studied in brassica napus, and subjected todifferent supplementary bands of ultraviolet radiation (uv-a, uv-b and uv-c). this study showed thatuv-b and uv-c induced oxidative stress as evidenced by an increase in lipid peroxidation and totalascorbate content. under uv-b and uv-c treatments, flavonoids and anthocyanins were increasedsignificantly co...

Beside the well-established impact on decreasing the risk of cardiovascular diseases (1), recent attention has been paid to the relationship between cocoa-containing foods and the immune system (2), showing that dark chocolate consumption enhances the systemic defense against bacterial (3) and viral (4) infections. Hence, the current study aimed at investigating the acute effect of dark chocola...

As email becomes one of the most convenient and indispensable communication mediums in our life, it is very important to protect email users from increasing email worm attacks. In this paper, we present the architecture and system design of a “feedback email worm defense system” to protect email users in enterprise networks. The defense system is flexible and able to integrate many existing det...
