Human organ system

When the major transition from an animal population to human subjects is proposed, the statistical probabilities derived by the statistician must be discussed by experts familiar with the similarities and differences between human organ systems and cell surface receptors and those of the laboratory animals. Thus, the extrapolations in the IND from the preclinical work in animals to the probable effects in humans rest on a combination of statistical inferences and comparative assessments by experts in pharmacology, toxicology, pathology, and biochemistry. Their expertise, in turn, rests to some extent on the statistical...

The devices capable of functioning while introduced to microbes are primarily embedded into the human organ systems replete with normal and pathogenic microbiota such as excretory and digestive systems. The majority of microbes affect the material directly, using its surface as a substrate for adhesion and colonization.

Peroxide oxidation processes in human organism are one of based phenomena that is responsible for homeostasis. For this reason development and investigation of interaction mechanism between different biomacromolecules and lipids peroxide are important for forming complete picture of functioning of human being as biological system. 

Humans experience a wide range of acute adverse health effects, including irritation, narcosis, asphyxiation, sensitization, blindness, organ system damage, and death. In addition, the severity of many of these effects varies with intensity and duration of e.xposure. For example, exposure to a substance at an intensity that is sufficient to cause only mild throat irritation is of less concern than one that causes severe eye irritation, lacrimation, or dizziness, since the latter effects arc likely to impede escape from the area of contamination.

Case reports of human poisonings and studies in animals indicate that during acute oral exposure to lethal or near-lethal amounts of endosulfan, involvement of a large number of organ systems (respiratory,... 

The nervous system is one of the two regulatory systems in the human body that influences the activity of all the other organ systems. It consists of literally billions of neurons interconnected in a highly organized manner to form circuits. The number of neurons and the manner in which they are interconnected in a given circuit distinguishes one region of the brain from another and the brain of one individual from that of another. In addition, plasticity, the ability to alter circuit connections and function in response to... 

This chapter will provide an in-depth summary of the immunotoxicity of JP-8 as learned from human, animal, and in vitro studies. For additional reading regarding the toxicity to other organ systems, readers are guided to a comprehensive review recently published by the National Research Council [1],... 

As with the development of other organ systems, the development of the immune system is a highly regulated process. Table 19.1 and Figure 19.1 provide a list of known events or markers that occur during immune system development. In humans, hematopoiesis begins at approximately 3-4 weeks of gestation with the development of blood...
