Self-Protection

Current limiting devices need not be protected, since they are already very fast acting and. hence, self-protected. 

Selfcare precautions mean exactly that. The rescuer must take self protective actions to keep from becoming another victim and thereby part of the problem rather than part of the solution. 

Kaxp channels under investigation resulted in selective rescue of substantia nigra dopaminergic neurons does not prove a deleterious, neurodegeneration-promoting role of Katp channels, but may simply mean that the dopamine neurons, lacking KATP channels, have developed other, undetected self-protection mechanisms. 

The efficient removal of O2 and H2O2 vvill diminish OH formation and therefore antioxidant defence systems have evolved to limit their accumulation. Enzymic and low molecular weight antioxidants exist to scavenge free radicals as self-protection mechanisms. Some proteins exhibit antioxidant properties because they chelate transition-metal catalysts. The significance of antioxidants in relation to inflammatory joint disease is discussed below. 

HOCl is one of the oxidants that activated phagocytes have in their arsenal. Hu et al. (1993) have shown that plasma albumin sulphydryl and ascorbic acid both protect against oxidant injury from HOCl. Neutrophils, interestingly, contain about 25 times more ascorbic acid than plasma. This su ests an endogenous self-protection role. This work is important because of the biological emphasis of reactive chlorine by the neutrophil. 

Sulfur vesicants These agents are insoluble in water and form self-protecting decomposition products at the water/agent interface that prevent hydrolysis of the agent. These decomposition products are stable and some of them have toxic and/or vesicant properties. 

Vomiting/sternatory agents decompose slowly in water. Some agents are self-protecting and form an oxide coating that delays further hydrolysis. Agents may be corrosive to some metals.

Remember, too, that treatment is a business enterprise, and because of this many treatment centers are concerned about the bottom line. Some treatment centers provide high-quality programs, but in other instances the concern about economics overrides concern about client care. This is not a knock on the treatment industry, because the balancing act among economic solvency, profit, and quality of services is true across all other types of health care as well. As a matter of self-protection, try to judge for yourself whether the program you are contemplating has your best interests at heart. 

In Australian tenebrionid beetles, defensive compounds and their patterns seem to be of only low chemotaxonomic value. However, the aforementioned aromatic compounds are restricted to the genus Tribolium. Abdominal defensive compounds were used as chemosystematic characters in order to construct a phylogenetic tree for the genus Tribolium [330]. The defensive secretion of adults of Tenebrio molitor was shown to contain toluquinone 7 and m-cresol 89 [333]. The quantification of benzoquinones in single individuals of Tribolium castaneum at different days after adult eclosion indicates that the amount of toxic quinone only shows a maximum subsequent to cuticle sclerotization. Obviously, there is a need for an adequate cuticular barrier for self-protection from these defensive compounds [334]. 

Aluminum is a self-protecting metal. It readily forms an impervious coating of AI2O3 that protects the aluminum from further corrosion. Does this reaction occur spontaneously at all temperatures Explain your answer. 

Under certain circumstances, anxiety is an appropriate emotional response. We expect a person to feel sad after a signihcant loss such as the death of a loved one, and it is eqnally reasonable for a person to feel fearful and anxious when faced with a frightening situation such as a painful or risky medical procedure. Indeed, in the context of the fight or flight reaction readily witnessed in nature when a predator is lurking near its intended prey, the physical and mental symptoms of anxiety can indeed be adaptive. This anxiety clearly serves as an appropriate alarm that potential danger is nearby and readies the individnal for a self-protective response. 

Self-protection. To prevent blood loss when a vessel is injured, the blood has systems for stanching blood flow and coagulating the blood (hemostasis see p. 290). The dissolution of blood clots (fibrinolysis) is also managed by the blood itself (see p. 292).

Highly influential but controversial study of the risks of keeping firearms in the home. The authors conclude that there are 43 suicides, criminal homicides, or accidental gunshot deaths for every case of homicide for self-protection. 

Senturia, Yvonne D., et al. Gun Storage Patterns in U.S. Homes with Children A Pediatric Practice-Based Survey. Archives of Pediatrics Adolescent Medicine, vol. 150, March 1996, pp. 265ff. Finds that the majority of gun owners do not lock up their guns and that persons who use guns at work or for self-protection are most likely to have them loaded at home. The authors suggest that children s doctors talk to parents about the need to store firearms safely.
