Microorganisms are able to degrade a large variety of compounds, including pesticides under laboratory conditions. However, methods have yet to be developed to decontaminate the environment from residues of pesticides. Pesticidal degradative genes in microbes have been found to be located on plasmids, transposons, and/or on chromosomes. Recent studies have provided clues to the evolution of degradative pathways and the organization of catabolic genes, thus making it much easier to develop genetically engineered microbes for the purpose of decontamination. Genetic manipulation offers a way of engineering microorganisms to deal with a pollutant, including pesticides that may be present in the contaminated sites. The simplest approach is to extend the degradative capabilities of existing metabolic pathways within an organism either by introducing additional enzymes from other organisms or by modifying the specificity of the catabolic genes already present. Continuous efforts are required in this direction, and at present several bacteria capable of degrading pesticides have been isolated from the natural environment. Catabolic genes responsible for the degradation of several xenobiotics, including pesticides, have been identified, isolated, and cloned into various other organisms such as Streptomyces, algae, fungi, etc. In addition, recombinant DNA studies have made it possible to develop DNA probes that are being used to identify microbes from diverse environmental communities with an unique ability to degrade pesticides.
Inflammation plays an important role in maintaining the body's homeostasis. It repairs the damaged tissues of the body resulting from injury or infection. In addition, a diverse array of diseases like hepatitis, arthritis and colitis has been reported and described to be associated with inflammatory processes. Some autoimmune diseases like inflammatory bowel disease (IBD) emerge by the influence of numerous genes in complex environmental situations belong to inflammation. The currently available processes for curing inflammation and related disorders facilitate the use of non steroidal antiinflammatory drugs (NSAIDs). Moreover, intolerable side effects are also associated with the consumption of these medications. It is well known that phenolic compounds, largely present in vegetables and fruits, serve as an integral part of normal human diet besides having great medicinal value. These are considered to reflect a variety of anti-inflammatory properties, and can be used as an alternate natural source for the prevention of chronic inflammatory disorders. This mini-review summarized the antiinflammatory benefits of plants derived very prominent dietary polyphenolic compounds particularly, Oleocanthal, Curcumin, Resveratrol and Quercetin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
