A Randomized Comparison of Different Vaginal Self-sampling Devices and Urine for Human Papillomavirus Testing-Predictors 5.1.

Background: Human papillomavirus (HPV)-based screening is rapidly replacing cytology as the cervical screening modality of choice. In addition to being more sensitive than cytology, it can be done on self-collected vaginal or urine samples. This study will compare the high-risk HPV positivity rates and sensitivity of self-collected vaginal samples using four different collection devices and a urine sample.

Determinants of Human Papillomavirus Vaccine Uptake by Adult Women Attending Cervical Cancer Screening in 9 European Countries.

Introduction: Human papillomavirus-vaccinated cohorts, irrespective of age, will likely reduce their subsequent screening requirements, thus opening opportunities for global cost reduction and program sustainability. The determinants of uptake and completion of a 3-dose human papillomavirus vaccination program by adult women in a European context were estimated.

Study Design: This was an intervention study.

Inclusion of viologen cations leads to switchable metal-organic frameworks.

The reactions of Zn(NO)·6HO with the polycarboxylic acids 1,3-benzenedicarboxylic acid (Hmbdc), 1,4-benzenedicarboxylic acid (Hbdc), 1,3,5-benzenetricarboxylic acid (Hbtc) and 4,4'-biphenyldicarboxylic acid (Hbpdc) in the presence of methyl viologen iodide ([MV]I) in DMF gave anionic frameworks with methyl viologen species incorporated as counter-ions. When the reactions were carried out at 120 °C, the blue products [MV][Zn(mbdc)] (1-ht), [MV][HMV][NMeH][Zn(bdc)]·0.6DMF (2-ht), [MV][Zn(btc)]·DMF (4-ht) and [MV][Zn(bpdc)]·8DMF·10HO (5-ht) were formed, and these were shown to contain the radical cation [MV]˙.

The effect of metal distribution on the luminescence properties of mixed-lanthanide metal-organic frameworks.

A series of lanthanide metal-organic frameworks (MOFs) of the general formula [Ln(Hodip)(HO)]·nHO (Sm, 1; Eu, 2; Gd, 3; Tb, 4; Dy, 5; Er, 6; Hodip = 5,5'-oxydiisophthalic acid) have been prepared and shown crystallographically to have isostructural three-dimensional frameworks. The fluorescence emission spectra of the europium compound 2, which is red, and the terbium compound 4, which is green, show characteristic peaks for transitions involving the metal centres, whereas that for the gadolinium compound 3 is dominated by transitions involving Hodip. Using a 1 : 1 : 1 mixture of europium, gadolinium and terbium nitrates in the synthesis resulted in the mixed-metal MOF [GdTbEu(Hodip)(HO)]·nHO 7, for which the ratio of the metal ions was determined using EDX spectroscopy.
