conclusions multiplex sybr green real-time pcr is a rapid and relatively inexpensive method for detection of respiratory viruses. results application of the multiplex sybr green real-time pcr in clinical samples from 172 patients in a one-year study resulted in detection of 19 (11.04%) piv3, 9 (5.23%) piv4, and 1 (0.58%) coronavirus nl63. all the positive samples were detected during december t...

background and aims. the aim of this clinical investigation was to compare clinical and microbiological effectiveness of adjunctive chx gel in the treatment of periodontitis. materials and methods. twenty-four subjects with localized or generalized moderate-to-severe chronic periodontitis underwent scaling and root planing. one tooth in each quadrant with a probing depth of >4 mm was chosen for...

backgoround: plant diseases, caused by a wide range of phytopathogenic fungi, could be managed using of trichoderma sp, as a biocontrol agent. cell wall degrading enzymes like chitinase from t. harzianum are important means for fungal pathogen inhibition. overexpression of these chitinase enzymes can improve the antagonistic potential of trichoderma sp. strains. objectives: this study aimed to ...

a real-time optimization (rto) strategy incorporating the fuzzy sets theory is developed, where the problem constraints obtained from process considerations are treated in fuzzy environment. furthermore, the objective function is penalized by a fuzzified form of the key process constraints. to enable using conventional optimization techniques, the resulting fuzzy optimization problem is then re...

plants are naturally exposed to frequent changes in environmental conditions such as salt stress affecting their growth and development, and consequently a considerable reduction in total productivity. monodehydroascorbate reductase (mdhar), a key enzyme in ascorbate-glutathione cycle, serves as an important antioxidative enzyme in scavenging of reactive oxygen spices (ros). in this study, mdha...

objective: in this study, a sybr green real-time rt-pcr assay for quantification of hiv-1 viral rna was developed. materials and methods: this assay was performed based on amplification of the pol region of hiv-1 and product analysis by an abi 7500 system. we quantified hiv-1 viral load in 26 seropositive patients by this system and the data were subsequently compared with results obtained wit...
