Transgenic sorghum plants (Sorghum bicolor L. Moench, cv. SRN39) were obtained by microprojectile-mediated DNA delivery (Bio-Rad PDS 1000/He Biolistic Delivery System) to explants derived from immature inflorescences. Explants were precultured on medium supplemented with 2.5 mg/l (11.31 µM) 2,4-D, 0.5 mg/l (2.32 µM) kinetin, and 60 g/l sucrose for 1 to 2 wk(More)
OBJECTIVE Candidate gene association studies and genome-wide association studies (GWAs) have identified a large number of single nucleotide polymorphisms (SNPs) loci affecting susceptibility to rheumatoid arthritis (RA). However, for the same locus, some studies have yielded inconsistent results. To assess all the available evidence for association, we(More)
Our aim was to determine the usefulness of fluorescence examination and photodynamic therapy (PDT) for the management of perianal extramammary Paget’s disease. A 75-year-old woman underwent two courses of PDT. The first treatment was carried out with topically applied 5-aminolevulinic acid (ALA) to the affected area (2.5 × 2.5 cm2) 3 h before light(More)
OBJECTIVE To compare the short-term curative effect of photodynamic therapy (PDT), PDT combined with chemotherapy and chemotherapy alone on the advanced esophageal cancer patients. METHODS Retrospective analysis of 90 patients of esophageal cancer underwent PDT, PDT combined with chemotherapy and chemotherapy alone from 2004 to 2007 (stages III-IV),(More)
OBJECTIVE To investigate the effectiveness and side effects of photofrin-photodynamic therapy (PDT) for intractable bronchial lung cancer. METHODS Thirty patients were classified as stage II-IV intractable bronchial lung cancer with lumen obstruction after they failed previous treatment regimens such as surgery, radiotherapy and chemotherapy. PDT was(More)
Polychlorinated biphenyls (PCBs) and 2,4-dichlorophenol (2,4-DCP) generally led to mixed contamination of soils as a result of commercial and agricultural activities. Their accumulation in the environment poses great risks to human and animal health. Therefore, the effective strategies for disposal of these pollutants are urgently needed. In this study,(More)
One of the major limitations in bioremediation of polychlorinated biphenyls (PCBs) in contaminated soils is their low water solubility and high adsorbability. In the present study, effectiveness of recombinant protein AlnA as a biosurfactant in increasing extractability of PCBs was first investigated. The AlnA surface tension measurements allowed for(More)
A novel 2,4-dichlorophenol hydroxylase (TfdB, EC gene, designated as tfdB-JLU, was identified from a metagenome constructed from polychlorinated biphenyl-contaminated soil by functional screening and heterologously expressed in Escherichia coli. The deduced amino acid sequence of tfdB-JLU exhibited less than 48% homology with other known TfdBs.(More)
To make a comprehensive assessment on monosodium glutamate wastewater pollution, a pollution exposure experiment was carried out on the seed germination and root elongation of wheat, Chinese cabbage and tomato by using the wastewater discharged from different processing phases of monosodium glutamate production. The results showed that there were(More)
Water-treatment flocculants are being developed from traditional to inorganic, from inorganic to organic, from natural organic to synthetic organic, from synthetic organic to modified natural organic, from inorganic or organic to inorganic-organic, and from chemical to biological with ecological safety. In order to promote the rapid development and(More)
