However, the majority of current biochemical tests for body fluid identification, which are applicable at the crime scene, are presumptive and destructive to the sample. Raman Spectroscopy provides a suitable alternative to current methods as a nondestructive, confirmatory, and potentially in field method. Our laboratory has developed a chemometric model for the identification of five main body fluids using Raman spectroscopy. This model was developed using samples obtained from healthy donors. Thus, it is of most importance for the forensic application of the method to validate its performance for donors with diseases that might affect the biochemical composition of body fluids. In this study, the developed method was validated using peripheral blood samples acquired from donors with Celiac Disease, Sickle Cell Anemia, and Type 2 Diabetes. It was shown that the method correctly identified all samples as peripheral blood indicating that no false positives could occur because the blood traces were originated from donors suffering from the diseases.展开更多

Each life has four grades.There are four different “me” in each life: true me, Yang me, Yin me and conscious me. True me never dies while Yang me, Yin meand conscious me all appear and go. The heart of life is also a system consisting of four grades (true heart + Yang me heart + Yin meheart + conscious heart). Life is a four-seasonal whole dominated by heart. True me is true while Yang me, Yin me and conscious meare false. The general law of the universe is an operating body of general rules. Both the operating body of general rules and the lifebody are combination of the true and the false. The operating body of general rules is a body with two aspects and the combinationand an autonomous operation of movement with stillness, gathering with parting and rising with falling. The operating body ofgeneral rules dominated by true me is the universe body. The essential features of the universe body include: 1) it is empty;2) it isabsolutely quiet;3) it exists forever;4) it contains seeds for everything;5) it generates everything in the universe;6) it is solid andwill never break;7) its power is King Kong power. The zero-state of the galaxy is its basic state and the giant blank zone of theuniverse. The galaxy’s turning from zero-state into one-state is getting something from nothing. The operating of general rule ispresented as the four-seasonal movement or metabolism of life. It is a continuity of movement and stillness (life and death) and aprocess of something interacting with nothing. The modes of reproduction of life consist of self-generation, generation byaugmentation and generation by transformation. The Milky Way Galaxy, the solar system and the earth are inorganic life withreproductive system and reproductive capacity. In the positive-going evolution, their inner morality power gradually decreases andundergoes different states and structures. Internal intercourse generates different lives. In the early days of the earth, the temperaturewas high and inorganic lives first appeared: humans, animals, plants and bacteria. When the temperature dropped to a proper degree,organic lives then appeared: bacteria, plants, animals and humans. Now, new lives are still appearing on the earth.展开更多
