TL;DR: The observed detrimental effect of photocatalysts on various microorganism groups decreases in the order: E. coli > S. aureus approximately E. faecalis>>C.
Abstract: Visible light induced photocatalytic inactivation of bacteria (Escherichia coli, Staphylococcus aureus, Enterococcus faecalis) and fungi (Candida albicans, Aspergillus niger) was tested. Carbon-doped titanium dioxide and TiO2 modified with platinum(IV) chloride complexes were used as suspension or immobilised at the surface of plastic plates. A biocidal effect was observed under visible light irradiation in the case of E. coli in the presence of both photocatalysts. The platinum(IV) modified titania exhibited a higher inactivation effect, also in the absence of light. The mechanism of visible light induced photoinactivation is briefly discussed. The observed detrimental effect of photocatalysts on various microorganism groups decreases in the order: E. coli > S. aureus ≈ E. faecalis ≫ C. albicans ≈ A. niger. This sequence results most probably from differences in cell wall or cell membrane structures in these microorganisms and is not related to the ability of catalase production.

TL;DR: The current investigation demonstrated the dynamics of vessel wall changes after implantation of a bioresorbable scaffold, resulting at three years in stable luminal dimensions, a low restenosis rate and a low clinical major adverse cardiac events rate.
Abstract: Aims: To assess observations with multimodality imaging of the Absorb bioresorbable everolimus-eluting vascular scaffold performed in two consecutive cohorts of patients who were serially investigated either at 6 and 24 months or at 12 and 36 months. Methods and results: In the ABSORB multicentre single-arm trial, 45 patients (cohort B1) and 56 patients (cohort B2) underwent serial invasive imaging, specifically quantitative coronary angiography (QCA), intravascular ultrasound (IVUS), radiofrequency backscattering (IVUS-VH) and optical coherence tomography (OCT). Between one and three years, late luminal loss remained unchanged (6 months: 0.19 mm, 1 year: 0.27 mm, 2 years: 0.27 mm, 3 years: 0.29 mm) and the in-segment angiographic restenosis rate for the entire cohort B (n=101) at three years was 6%. On IVUS, mean lumen, scaffold, plaque and vessel area showed enlargement up to two years. Mean lumen and scaffold area remained stable between two and three years whereas significant reduction in plaque behind the struts occurred with a trend toward adaptive restrictive remodelling of EEM. Hyperechogenicity of the vessel wall, a surrogate of the bioresorption process, decreased from 23.1% to 10.4% with a reduction of radiofrequency backscattering for dense calcium and necrotic core. At three years, the count of strut cores detected on OCT increased significantly, probably reflecting the dismantling of the scaffold; 98% of struts were covered. In the entire cohort B (n=101), the three-year major adverse cardiac event rate was 10.0% without any scaffold thrombosis. Conclusions: The current investigation demonstrated the dynamics of vessel wall changes after implantation of a bioresorbable scaffold, resulting at three years in stable luminal dimensions, a low restenosis rate and a low clinical major adverse cardiac events rate.

TL;DR: It is concluded that certain functionalized fullerenes have potential as novel PDT agents and phototoxicity may be mediated both by superoxide and by singlet oxygen.

TL;DR: This study analysed eight DNA methylation candidate loci using convenient and reliable pyrosequencing technology and developed a deterministic age prediction model that was deterministic for individuals belonging to these two extreme age categories.
Abstract: Forensic DNA phenotyping needs to be supplemented with age prediction to become a relevant source of information on human appearance Recent progress in analysis of the human methylome has enabled selection of multiple candidate loci showing linear correlation with chronological age Practical application in forensic science depends on successful validation of these potential age predictors In this study, eight DNA methylation candidate loci were analysed using convenient and reliable pyrosequencing technology A total number of 41 CpG sites was investigated in 420 samples collected from men and women aged from 2 to 75 years The study confirmed correlation of all the investigated markers with human age The five most significantly correlated CpG sites in ELOVL2 on 6p242, C1orf132 on 1q322, TRIM59 on 3q2533, KLF14 on 7q323 and FHL2 on 2q122 were chosen to build a prediction model This restriction allowed the technical analysis to be simplified without lowering the prediction accuracy significantly Model parameters for a discovery set of 300 samples were R 2 =094 and the standard error of the estimate=45 years An independent set of 120 samples was used to test the model performance Mean absolute deviation for this testing set was 39 years The number of correct predictions ±5 years achieved a very high level of 867% in the age category 2–19 and gradually decreased to 50% in the age category 60–75 The prediction model was deterministic for individuals belonging to these two extreme age categories The developed method was implemented in a freely available online age prediction calculator
