[Correlation of interleukin-13 gene - 1112c/T polymorphism with asthma and total plasma IgE levels].

Objective: To investigate the correlation of - 1112C/T polymorphism of Interleukin-13 (IL-13) gene promoter with asthma and its effect on total plasma IgE levels.

Methods: One hundred asthmatic patients (the asthma group) and 100 healthy controls (the control group) were recruited. Polymerase chain reaction/restriction fragment length polymorphism (PCR/RFLP) techniques were used to determine the - 1112 locus polymorphism, and the total plasma IgE levels were determined by ELISA.

A preliminary phylogeny of the Pentatomomorpha (Hemiptera: Heteroptera) based on nuclear 18S rDNA and mitochondrial DNA sequences.

Pentatomomorpha is the second suborder in size only to Cimicomorpha in Heteroptera. However, the phylogenetic relationships among members of the suborder are not well established. Sequences from partial nuclear ribosomal 18S gene and mitochondrial COX1 gene were analyzed separately and in combination to generate a preliminary molecular phylogeny of Pentatomomorpha based on 40 species representing 17 putative families.
