Background: The inflammatory process is a physiological response to a vast number of harmful stimulus that takes place in order to restore homeostasis. Many drugs used in pharmacotherapy are effective to control inflammatory responses, however, there is a range of adverse effects attributed to steroidal and non-steroidal anti-inflammatory drugs (NSAIDs). In this sense, herbal medicine and derivatives have gained m Read More

Background: Laccase, a multicopper oxidoreductase (EC: 1.10.3.2), is a widely used enzyme in bioremediation of textile dye effluents. Fungal Laccase is preferably used as a remediating agent in the treatment and transformation of toxic organic pollutants. In this study, crude laccase from a basidiomycetes fungus, Phanerochaete sordida, was able to decolorize azo, antroquinone and indigoid dyes. In addition, interactions b Read More

Background and Objectives: In this study, three naturally isolated species of microalgae were investigated for their antioxidant activity using DPPH assay and polyphenol contents through Folin-ciocalteu analysis. Methods: Three different solvents including hexane, ethyl acetate and water, which present different polarities were utilized to extract the bioactive components from three different microalgal strains. Results: The investi Read More

Background & Objectives: In our previous investigation, oral administration of 1,8- cineole-rich supercritical carbon dioxide extract of small cardamom seeds in Wistar albino rats resulted in achieving normal fasting blood glucose (FBG) and serum cholesterol levels. The objective of this study was to further protect the aforesaid extract and to enhance its in vivo therapeutic efficacies in redressing type 2 diabetes and hyp Read More

Background: The Human Cytomegalovirus (HCMV) has infected more than 90% of the world population and its prevalence can be related to the individuals geographical and socialeconomic status. Serological tests based on ELISA are pivotal for HCMV diagnosis. Due to the lack of standardization in the production/purification of antigens from viral preparations, ELISA tests are based on several recombinant proteins Read More
