Proteins acting as powerful inhibitors of plant pectin methylesterase and polygalacturonase were isolated from whole lemon fruits (Citrus limon L.). Pectin methylesterase inhibitor (PMEI) and polygalacturonase inhibitor protein (PGIP) were purified using DEAE Sepharose column, resulting in fold purity of 89.13 and 81.16 and having a molecular mass of 35 and 38 kDa, respectively as estimated using SDS-PAGE and MALDI-TOF mass spectroscopy. The optimum pH of purified PMEI and PGIP was pH 6 and pH 4.5 while the inhibitors showed good stabil

1S. The plasmid copy number of pBp15.1S in exponentially growing B. pumilus cells was determined to be 33 copies per chromosome. After an extensive plasmid characterization, no known virulence factor was found so a search in the other extrachromosomal elements of the bacteria is needed.Erythropoietin (EPO) plays a critical role in the development of the nervous system. In this study, the effects of EPO in carbon monoxide (CO) neurotoxicity were examined. Rats were exposed to 3000 ppm CO for 1 h and then different doses of EPO were adminis
