Abstract: Disclosed are a device for protecting crops from wildlife, comprising an optical base film on both sides of which fluorescent holograms of natural enemies with both eyes and optionally claws or talons are laser printed while a composition containing a phosphorescent material and a repellent is applied to both eyes, and optionally to the claws or talons, and a method for fabricating the same. Oils and extracts from herbs are used selectively as ingredients in the repellent depending on repelling targets, that is, mammals, rodents and birds. In addition, the use of phosphorescent material exerts a repellent effect on nocturnal animals. Thus, the device exhibits high durability and can be used for protection from wildlife damage in various targets.

Abstract: Method and compositions for determining oxidative stress in a subject are provided in which presence of an aldehyde in a biological fluid is correlated with an oxidative stress in a subject. A test reagent having a pH regulator, a reducing agent, and an aldehyde-reactive chromogen is mixed with the biological fluid, and the color of the resulting aldehyde-modified chromogen is correlated with the oxidative stress.

Abstract: Urine is tested for presence of malondialdehyde by mixing it with a reagent consisting of about 90-110 parts 20% acetic acid, about 13.5-16.5 parts Ingredient A, and about 4.5-5.5 parts Ingredient B, wherein Ingredient A is comprised of sodium metabisulfite, phosphoric acid and deionized water in the proportions of about 18-22 grams sodium metabisulfite, 9-11 ml of concentrated phosphoric acid, and about 450-550 ml deionized water, and Ingredient B is comprised of basic fuchsin and Ingredient A in the proportion of about 0.45-0.55 grams basic fuchsin to about 90-110 ml Ingredient A. A color change is observed when malondialdehyde is present in the urine in a concentration greater than about 2 ppm.
