INTRODUCTION: Pharmacotherapy of overactive bladder (OAB) typically involves treatment with an antimuscarinic or mirabegron, a β3-adrenoceptor agonist, but real-world evidence on their use, including treatment access, persistence, and switching, is limited. Here, we describe the design of a prospective, multicenter, non-interventional registry of patients beginning a new course of OAB pharmacological therapy in routine clinical practice. METHODS: Adults with an OAB diagnosis for at least 3 months who either initiated a new course of mirabegron or antimuscarinic, or who switched therapy were enrolled into PERSPECTIVE (A Prospective, Non-intErventional Registry Study of Patients Initiating a Course of Drug Therapy for OveractIVE Bladder)...

The World Health Organization estimates more than 270,000 deaths annually by cervical cancer. Present vaccines are prophylactic in nature which cannot treat huge bulk of cervical cancer patients worldwide. Available therapies like radiotherapy, chemotherapy, or surgery are not effective in high-grade lesion, and hence, there is an unmet medical need for an effective form of therapy. T cells play a significant role in cervical cancer pathogenesis as human papilloma virus uses multiple mechanisms that dodge host T-cell immune-surveillance aiding in persistence of infection and establishment of cancer...

In this tutorial, we want to demonstrate the significant potential of ion mobility spectrometry (IMS), an analytical technique for identification and quantification of gas-phase compounds, in particular combined to other useful analytical tools. Coupled to gas-chromatographic pre-separation (GC-IMS), selectivity can be improved significantly, thus enabling the analysis of complex, humid mixtures. In-line pre-concentration can improve sensitivity down to the ppqV range. Furthermore, the use of non-radioactive ionisation sources in the near future could gain acceptance and will avoid legal restrictions...

Infection with high-risk human papillomavirus (HPV), most often HPV16, is associated with the development of anogenital and oropharyngeal cancers. Recently, ozone therapy was reported to have considerable efficacy against rabbit VX2 tumors, induced by the cottontail rabbit papillomavirus. The present study aims to determine whether similar results can be obtained in HPV16-transgenic mice, possibly paving the way for new therapeutic options against HPV-induced cancers. HPV16-transgenic and wild-type, female, 20 weeks-old mice were injected intraperitoneally with medical O3 /O2 (80░mL/kg, at O3 50░μg/mL), once a day, for 5 consecutive days...
