The edible mushrooms (basidomycetes) have high nutritional value, promote the immune system, and as a source of natural antimicrobial substances have been used to cure bacterial infections since ancient times.Various kinds of proteins with several biological activities are produced by mushrooms. In this research, in order to evaluate antibacterial activity of edible mushrooms, we isolated prote...

Neuro-inflammation is the inflammation of nervous tissue due to oxidative stress, aging and autoimmunity and the major cause of Alzheimer's, Parkinson's and Huntington's disease. Periodontitis, the inflammation of the gums and supporting structures of the teeth, is a chronic peripheral immuno-inflammatory condition, affiliated with gram- negative, anaerobic bacteria that cause low-grade systemi...

Nowadays, increasing in prevalence of multiple drug resistance implies the development of new synthetic antibacterial, antioxidative and anti-inflammatory drugs from alternative sources (Papadoupoulo et al., 2005). Therefore, there is a renewed interest in natural substances containing phytoconstituents that exhibited several biological properties. They are used in health to prevent oxidative d...

in this study, a functional colorant, berberine, extracted from berberis vulgaris wood was applied onto wool fiber using the extract of roots of rumex hymenosepolus as biomordant. the effect of treatment variables on the color strength of dyed fibers was examined. the fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. dyed samples were tested for antiba...

Penicillin and other antimicrobials discovery revolutionized medicine but, as a consequence of antibiotic misuse, several bacteria evolved to become resistant to multiple antibiotics classes: “the superbugs”. Following the stagnation on the conventional antibiotic-discovery field, scientific attention turned to alternative foundations for the development of novel antibacterial substances, namel...

UNLABELLED Plant-derived compounds and other natural substances are a rich potential source of compounds that kill or attenuate pathogens that are resistant to current antibiotics. Medieval societies used a range of these natural substances to treat conditions clearly recognizable to the modern eye as microbial infections, and there has been much debate over the likely efficacy of these treatme...

The antibacterial effect of 11 new commercially manufactured disinfectants on clinical isolates of Salmonella typhimurium DT104, Serratia marcescens and Pseudomonas aeruginosa was studied. The substances tested represented six pure quaternary ammonium substances (QAS) and five QAS combined with other ingredients. The antibacterial efficacy was characterized by influencing the growth of bacteria...

While antibiotic pollution has attracted considerable attention due to its potential in promoting the dissemination of antibiotic resistance genes in the environment, the antibiotic activity of their related substances has been neglected, which may underestimate the environmental impacts of antibiotic wastewater discharge. In this study, a real-time quantitative approach was established to eval...
