Recent research on vaginal microbiota relies high throughput sequencing while microscopic methods have a long history in clinical use. We investigated the correspondence between findings of Pap smears and composition determined by next generation among 50 asymptomatic women. Both produced coherent results regarding distinction Lactobacillus-dominant versus mixed microbiota, reassuring gynaecologists for use smear or wet mount microscopy rapid evaluation bacteria as part diagnosis. Cytologic...

Vaginal microbiota and its potential contribution to preterm birth is under intense research. However, only few studies have investigated the vaginal in later stages of pregnancy or at onset labour.We used 16S rRNA gene amplicon sequencing analyse cross-sectional swab samples from 324 Finnish women between 37-42 weeks gestation, sampled before elective caesarean section, spontaneous labour, pregnancies lasting ≥41 gestation. Microbiota data were combined with comprehensive clinical identify...

Abstract Many transition‐metal complexes can perform catalytic oxidations, but their corresponding reaction pathways are still not clear. In this study, the mechanism of Co(salen)‐catalyzed [salen = N , N' ‐bis(salicylidene)ethylenediamine] oxidization veratryl alcohol (3,4‐dimethoxybenzyl alcohol) by dioxygen in alkaline aqueous solution was elucidated with in‐situ ATR‐IR, Raman and UV/Vis spectroscopy. The seems to start formation a bis‐μ‐hydroxo[(Co(salen)] 2 species, which explains...

The stabilization of a mononuclear copper(II) complex with one MIm2Pr ligand [MIm2Pr = 3,3-bis(1-methylimidazol-2-yl)propionate] in the supercages zeolite Y was attempted, and resulting materials were tested for their activity oxidation catalysis. preparation procedure yielded initially two species (labeled 1 2) within pore system material, which differ molecular structure chemical composition as determined by UV/vis, ESR, IR, XAFS spectroscopy. In 1, copper found to be five-coordinated,...

Abstract Aim Patients with vascular anomalies are often misdiagnosed, leading to delayed or improper treatment. The aim of this study was evaluate the impact an interdisciplinary team on diagnosis and treatment paediatric patients anomalies. Methods We reviewed evaluated by our between 2002 2012, analysing referral diagnosis, final patient age, sex, clinical history, laboratory tests, imaging studies treatments. Results Of 480 who were evaluated, 435 (90.6%) had a anomaly: 30.7% all tumour...

Infertility is a global public health issue which leads many couples to seek fertility treatments, of in vitro fertilization (IVF) considered be the most effective. Still, only about one-third women achieve live birth after first IVF embryo transfer (IVF-ET). Factors affecting implantation are poorly known, but female reproductive tract microbiota may play key role. Our study confirms beneficial role vaginal lactobacilli, especially Lactobacillus crispatus, probability achieving clinical...

The Co(salen) catalyzed oxidation of veratryl alcohol by molecular oxygen in aqueous media was studied online ATR-IR spectroscopy. introduction dioxygen into the reaction mixture initiated formation aldehyde. Only product observed aldehyde and its amount noted to increase linearly with time when conditions are not changed. Addition NaOH during increases rate as active cobalt species increases. During a strong vibration is range cobalt–oxygen complexes at frequencies 981–993 cm−1. Based on...

Abstract Vaginal microbiota and its potential contribution to preterm birth has been under intense research in recent years. However, only few studies have studied vaginal later stages of pregnancy or at the onset labor. We analyzed swab samples collected between 37- 42-weeks gestation from 324 Finnish women before elective cesarean section, spontaneous labor, pregnancies continuing beyond 41 weeks gestation. composition associated strongly with parity, i.e. previous deliveries, advancing...

Abstract The cover picture shows the proposed mechanism of Co(salen)‐catalyzed oxidation a lignin model compound in water, as elucidated by several in‐situ spectroscopic techniques. Catalytic oxygen activation can help to prevent formation hazardous side products organic oxidations, especially if harmless solvents are used. target this work is lignin, which found wood and must be removed selectively possible before paper production. In view avoiding chlorine oxidant, idea catalytically...
