  2. Xenobiotic - Wikipedia

    en.wikipedia.org/wiki/Xenobiotic

    The term "xenobiotics", however, is very often used in the context of pollutants such as dioxins and polychlorinated biphenyls and their effect on the biota, because xenobiotics are understood as substances foreign to an entire biological system, i.e. artificial substances, which did not exist in nature before their synthesis by humans.

  3. Microbial biodegradation - Wikipedia

    en.wikipedia.org/wiki/Microbial_biodegradation

    Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...

  4. Environmental xenobiotic - Wikipedia

    en.wikipedia.org/wiki/Environmental_xenobiotic

    Pharmaceutical drugs are chemicals used for the alteration, diagnosis, prevention and treatment of disease, health conditions or structure/function of the human body. Some pharmaceutically active compounds (PhACs) can enter the environment by one route or another as the parent compound or as pharmacologically active metabolites.

  5. Xenobiotica - Wikipedia

    en.wikipedia.org/wiki/Xenobiotica

    Xenobiotica is a peer-reviewed medical journal that publishes comprehensive research papers on all areas of xenobiotics. It is published by Informa plc and covers six main areas: General xenobiochemistry , including in vitro studies concerned with the metabolism , disposition and excretion of drugs, and other xenobiotics, as well as the ...

  6. Drug metabolism - Wikipedia

    en.wikipedia.org/wiki/Drug_metabolism

    Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...

  7. Biological patents in the United States - Wikipedia

    en.wikipedia.org/wiki/Biological_patents_in_the...

    A gene patent is a patent on a specific isolated gene sequence, its chemical composition, the processes for obtaining or using it, or a combination of such claims. With respect to subject matter, gene patents may be considered a subset of the broader category of biological patents.

  8. Oxidative stress - Wikipedia

    en.wikipedia.org/wiki/Oxidative_stress

    Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

  9. Biological patent - Wikipedia

    en.wikipedia.org/wiki/Biological_patent

    A biological patent is a patent on an invention in the field of biology that by law allows the patent holder to exclude others from making, using, selling, or importing the protected invention for a limited period of time.
