An ortholog of the MADS-box gene SEPALLATA3 regulates stamen development in the woody plant Jatropha curcas.

Overexpression of JcSEP3 causes defective stamen development in Jatropha curcas, in which brassinosteroid and gibberellin signaling pathways may be involved. SEPALLATAs (SEPs), the class E genes of the ABCE model, are required for floral organ determination. In this study, we investigated the role of the JcSEP3 gene in floral organ development in the woody plant Jatropha curcas.

Influencing factors for saliva urea and its application in chronic kidney disease.

Objectives: To analyze possible influencing factors on concentration of saliva urea (SaU) and to validate its application in chronic kidney disease(CKD).

Design And Methods: Level of SaU in patients and normal subjects was researched.

Results: The concentration of SaU did not vary with sampling time and genders, but was related to ages and level of serum urea (U).

[Diversity of Escherichia coli in mechanical ventilated pneumonia by random amplified polymorphic DNA].

Objective: To understand the main gene types of Escherichia coli in mechanical ventilated pneumonia and to explore the mechanisms for drug resistance.

Methods: RAPD-PCR was used to analyze the fingerprinting of 20 strains of Escherichia coli. ESBLs were detected by double disk test.
