Security metrics have received significant attention. However, they have not been systematically explored based on the understanding of attack-defense interactions, which are affected by various factors, including the degree of system vulnerabilities, the power of system defense mechanisms, attack (or threat) severity, and situations a system at risk faces. This survey particularly focuses on h...

A central tenet of economics is that individuals respond to incentives. For psychologists and sociologists, in contrast, rewards and punishments are often counterproductive, because they undermine “intrinsic motivation”. We reconcile these two views, showing how performance incentives offered by an informed principal (manager, teacher, parent) can adversely impact an agent’s (worker, child) per...

The Defense Mechanisms Rating Scales (DMRS), one of the most widely used and validated instruments in the study of defense mechanisms, does not include psychotic defenses. The Psychotic-DMRS (P-DMRS) has been developed to include 6 psychotic defense mechanisms: psychotic denial, autistic withdrawal, distortion, delusional projection, fragmentation, and concretization. We discuss psychotic defen...

In "gene-for-gene" interactions between plants and their pathogens, incompatibility (no disease) requires a dominant or semidominant resistance (R) gene in the plant, and a corresponding avirulence (Avr) gene in the pathogen. Many plant/pathogen interactions are of this type. R genes are presumed to (a) enable plants to detect Avr-gene-specified pathogen molecules, (b) initiate signal transduct...

This study investigated the stimulation of specific host defenses to IHNV that are created by prior exposure to an avirulent reovirus (chum salmon reovirus; CSV). Preexposure of rainbow trout to CSV for 1 h resulted in a relative percent survival that ranged from 68 to 100% when fish were challenged with IHNV over an 8 week period. The levels of serum neutralizing antibodies detected 28 d after...

INTRODUCTION Inflammatory markers play a very important role in body's defense mechanism. Pro-inflammatory markers and anti-inflammatory markers counterbalance each other. It is extremely essential for the body to maintain their balance for a good immune response. OBJECTIVES To study the effect of yoga practices on selected pro-inflammatory and anti-inflammatory cytokine among industrial work...

Deoxynivalenol (DON) is a mycotoxin affecting wheat quality. The formation of the "masked" mycotoxin deoxinyvalenol-3-glucoside (D3G) results from a defense mechanism the plant uses for detoxification. Both mycotoxins are important from a food safety point of view. The aim of this work was to analyze DON and D3G content in inoculated near-isogenic wheat lines grown at two locations in Minnesota...

Juvenile shrimps (Penaeus monodon) weighing about 15-20 gms were procured from the grow-out ponds and reared under laboratory conditions. They were challenged with Vibrio parahaemolyticus MTCC 451 and their LD50 value was evaluated. The ascorbic acid and the histamine activity of both the control and experimental groups were assessed. The results showed a marked decline in both the parameters a...

Subtilisin-like proteases (subtilases) are serine proteases that fulfill highly specific functions in plant development and signaling cascades. Over the last decades, it has been shown that several subtilases are specifically induced following pathogen infection and very recently an Arabidopsis subtilase (SBT3.3) was hypothesized to function as a receptor located in the plasma membrane activati...

The reaction between normal serum and hyaluronidase has been studied in vitro and under in vivo conditions in skin. Using in vitro conditions of incubation, serum exhibits antihyaluronidase activity as measured by assay of hyaluronidase spreading activity in skin. This confirms the work of others, who have previously described the serum inhibitory factor using other tests of hyaluronidase activ...
