Evaluation of Eosinophilic Cationic Protein as a Marker of Alveolar and Cystic Echinococcosis.

Echinococcosis is a neglected zoonotic disease and a worldwide public health problem caused by infection with the larval stages of taeniid cestodes of the genus . In vitro studies have demonstrated a protoscolecidal effect of eosinophilic cationic protein (ECP), a granule protein of eosinophilic granulocytes, against . Therefore, the main objective of this study was to evaluate ECP as a biomarker in the treatment of alveolar echinococcosis (AE) and cystic echinococcosis (CE).

Synergistic Effect of Cefazolin Plus Fosfomycin Against and in an Experimental Model.

This study investigated the synergistic and activity of cefazolin plus fosfomycin against methicillin-susceptible and methicillin-resistant (MSSA and MRSA) to provide the basis for a potential treatment alternative. Antimicrobial susceptibility and synergy tests were performed with five MSSA and five MRSA isolates using the broth microdilution and chequerboard assays, respectively. The efficacy of cefazolin plus fosfomycin for the treatment of MRSA infections was assessed using the survival assay.

Characters of DNA constitution in the rye B chromosome.

We have used chromosome microdissection and microcloning to construct a DNA library of the entire B chromosome (B) of rye. New rye B-specific sequences have been screened from this pool, blasted with other sequences and analyzed to elucidate the characters of DNA constitution and the possible pathway of the origin of the rye B chromosome. We report the discovery of a new sequence that is specific to the rye B centromere.

[Analysis on genetic diversity of different Salvia miltiorrhiza geographical populations in China].

Objective: To research on genetic diversity of different Salvia miltiorrhiza geographical populations in China.

Method: The genetic diversity of 27 S. miltiorrhiza geographical populations from ten provinces in China was estimated using amplified fragment length polymorphism (AFLP) markers.

[Multicolor FISH analysis of rDNA and telomere on spin-ach].

In this study, multicolor FISH analysis on metaphase chromosomes of spinach with biotin-labeled 25S rDNA, DIG-labeled telomere sequences and biotin-labeled and DIG-labeled 5S rDNA was performed. There were six 25S rDNA loci, which were located on the satellites of the third, the fifth and the sixth chromosomes, four 5S rDNA loci, which were located on the long arms of the third and the fifth chromosomes. The telomere loci were located on the end of the sixth chromosome and also on both the end and centromeric regions of other chromosomes.

[Karyotypes analysis of Ferula fukanensis].

Objective: Study on the karyotypes analysis of Ferula fukanensis.

Method: The young roots were treated with 0.000 2 mol x L(1) 8-Hydroxyquinoline for 3 h, carnoy's for 3 h, 1 mol x L(-1) HCl in 5 min,carbol fuchsin coloration for 2 min and the treated roots were utilizied to make the plate for observation.

[Study of a DNA sequence from brine shrimp artemia containing a novel DM domain].

Sex-determining mechanisms are highly variable between phyla. However, there is an apparent exception in which structurally and functionally related genes control sex determination in different phyla: the sexual regulators DSX of Drosophila melanogaster and MAB-3 of Caenorhabditis elegans both containing a DNA-binding motif, DM domain. Proteins containing the domain may also play a role in sexual development of vertebrates.

The molecular characterization of maize B chromosome specific AFLPs.

The origin and evolution of B chromosomes could be explained by the specific DNA sequence on them. But the specific sequences known were quite limited. To investigate maize B chromosome sqicific DNA sequeces, maize genomes with and without B chromosomes were analyzed by AFLP.
