Covalently bridged pillararene-based polymers (CBPPs) are a special class of macrocycle-based polymers in which multiple pillararenes monomers are attached to the polymer structures by covalent bonds. Owing to the unique...

Sex-determining region Y box-containing genes are transcription factors with roles in multiple biological processes, including cell differentiation, proliferation, and apoptosis. Sex-determining region Y box-containing genes have also been shown to act as regulators and biomarkers in the progression of many different cancers, including gynecological cancers such as ovarian, cervical, and endometrial cancer. In this review, we summarize the contrasting regulatory roles of Sex-determining region Y box-containing genes in different gynecological cancers, as promotors with high expression levels or as suppressors with low expression levels. Expression levels of Sex-determining region Y box-containing genes were also identified as biomarkers of clinical features, including International Federation of Gynecology and Obstetrics stage, histopathologic grade together with disease-free survival, and treatment efficacy in patients with gynecological cancers. An understanding of the mechanisms whereby Sex-determining region Y box-containing genes regulate the progression of gynecological cancers will aid in the development of novel diagnostic and therapeutic strategies, while analysis of Sex-determining region Y box-containing expression levels will help to predict the prognosis of patients with gynecological cancers.

A film-antenna capable of generating two wide resonant modes for covering the AMPS/GSM bands and the DCS/PCS/ UMTS bands for mobile phones is proposed. The antenna consists of two superimposed radiating arms which can support two resonant modes by themselves. The frequency range of a resonant mode generated by one of the arm is arranged to differ a little with the corresponding mode of the other, at the fundamental and higher-order modes. As a result, the bandwidths at both of the resonant modes are significantly enhanced. The antenna has a dimension of 5x15x40 mm 3 and shows fairly good omni-directional radiation patterns at all the operating bands.
