The overdosed ROS ultimately resulted in mitochondrial damage and cell death. These findings indicate that the surface-convertible nanoplatform is promising for improved photothermal anticancer therapy. Contact lens users very often become patients of allergic conjunctivitis, which is caused by protein and bacteria adsorption to the eye, because contact lenses easily adsorb proteins and bacteria. However, even if contact lens users develop eye diseases such as allergic conjunctivitis, most of them continue to use contact lenses to avoid interference to daily life or a decrease in their quality of life. If novel contact lenses able to prevent and additionally cure eye diseases can be manufactured, they could improve the quality of life of contact lens users worldwide. Thus, we aim to develop a novel material for contact lenses to prevent diseases by incorporating a zwitterionic polymer with the ability to suppress protein and bacteria adsorption. In addition, we also aim to effectively introduce and release a drug against allergic conjunctivitis from the contact lens material. Because the poorly water-soluble drug for allergic conjunctivitis (pranoprofen) forms a rigid crystal structure, we developed the novel "hot-melt press method" to construct a contact lens able to effectively release it. In the present study, polymer sheets containing carboxymethyl betaine (a kind of zwitterionic monomer), 2-hydroxyethyl methacrylate, and 1-vinyl-2-pyrrolidone were prepared using three different procedures. The sheets were hydrophilic and showed a strong resistance against protein and bacteria adsorption. The sheets prepared by the hot-melt press method were transparent and seemed to have potential as a material for contact lenses. In addition, the drug introduced into the sheets during preparation was observed to release at a practically appropriate dose. Therefore, it is expected that the sheets could possibly be used as a material for contact lenses which not only protect against the development of eye trouble due to protein and bacterial adsorption, but also heal allergic conjunctivitis. V.The corrosion behaviour of X80 pipeline steel was studied in a simulated marine environment inoculated with marine bacterium Marinobacter salsuginis. The electrochemical results showed that the increase in linear polarization resistance, charge transfer resistance, and the decrease in corrosion current density of the X80 pipeline steel immersed in the biotic medium indicated its high corrosion resistance compared to those in the abiotic medium. Surface morphological techniques including scanning electron microscopy, confocal laser scanning microscopy and live/dead cells staining were employed to observe the biofilm morphology and bacterial viability after different immersion times. X-ray photoelectron spectroscopy was used to analyse the oxides film formed on the steel surface. The obtained results indicated that the corrosion inhibition efficiency was obviously higher in the biotic medium compared to that in the abiotic medium. The high corrosion resistance of X80 steel in biotic medium was attributed to the formation of biofilm and the development of extracellular polymeric substances (EPS) layer on its surface. The highest spectral ripple density at which the discrimination of ripple glide direction was possible (STRtdir task) was assessed for one-octave wide (narrowband) stimuli with center frequencies of 500, 1000, 2000, and 4000 Hz and for a broadband stimulus. A pink noise lowpass filtered at the lower edge frequency of the rippled-noise stimuli was used to mask possible combination ripples. The relationship between thresholds measured using the STRtdir task and estimates of the sharpness of tuning (Q10) derived from fast psychophysical tuning curves was assessed for subjects with normal hearing (NH) and cochlear hearing loss (CHL). The STRtdir thresholds for the narrowband stimuli were highly correlated with Q10 values for the same center frequency, supporting the idea that STRtdir thresholds for the narrowband stimuli provide a good measure of frequency resolution. Both the STRtdir thresholds and the Q10 values were lower (worse) for the subjects with CHL than for the subjects with NH. For both the NH and CHL subjects, mean STRtdir thresholds for the broadband stimulus were not significantly higher (better) than for the narrowband stimuli, suggesting little or no ability to combine information across center frequencies. α-Glucosyl diacylglycerols (αGlc-DAGs) play an important role in providing protective immunity against Streptococcus pneumoniae infection through the engagement of the Macrophage inducible C-type lectin (Mincle). Herein, we efficiently synthesised αGlc-DAGs containing C12, C14, C16 and C18 acyl chains in 7 steps and 44-47% overall yields, and demonstrated that Mincle signaling was dependent on lipid length using mMincle and hMincle NFAT-GFP reporter cells. The greatest production of GFP in both cell types was elicited by C14 αGlc-DAG. Accordingly, C14 αGlc-DAG has potential to act as an adjuvant to augment the immune response against S. pneumoniae antigens. selleck chemicals llc OBJECTIVE The objective of this study was to examine the association between multivitamin use in the periconceptional period and the risk of preeclampsia. STUDY DESIGN The association was investigated in a prospective cohort study. 15,154 deliveries in women followed at a large university hospital in Denmark were included between 16 September 2012 and 31 October 2016. Pregnant women were sent a questionnaire containing items related to socio-demographic-, lifestyle- and health factors. The responses on multivitamin use were merged with the preeclampsia diagnosis from the Danish Medical Birth Registry. We used multiple logistic regression analyses to assess the association and to adjust for potential confounders. MAIN OUTCOME MEASURES The outcome of interest, preeclampsia, included the preeclampsia subtypes eclampsia and HELLP (Haemolysis, Elevated Liver enzymes, and Low Platelets) syndrome. RESULTS In total 12,954 women (85%) reported multivitamin use. A diagnosis of preeclampsia was found in 397 women (2.6%). We found a similar risk of preeclampsia in multivitamin user and non-users, adjusted odds ratio (AOR) for periconceptional multivitamin use = 0.97 (95% CI 0.70 to 1.36) and AOR for early pregnancy multivitamin use = 0.97 (95% CI 0.71 to 1.32). Subgroup analyses stratified on body mass index showed that among women with overweight, both periconceptional and early pregnancy multivitamin use were associated with a statistically significant lower risk of preeclampsia (AOR = 0.49, 95% CI 0.24 to 0.99 and AOR = 0.35, 95% CI 0.18 to 0.69, respectively). CONCLUSION Periconceptional- and early pregnancy multivitamin use was found to be associated with a similar risk of preeclampsia compared to non-users. Our review looks at recent advances in technologies applied to studying pollinators in the field. These include RFID, radar and lidar for detecting and tracking pollinators; wireless sensor networks (e.g. 'smart' hives); automated visual and audio monitoring systems including vision motion software for monitoring fine-scale pollinator behaviours over extended periods; and automated species identification systems based on machine learning that can vastly reduce the bottleneck in (big) data analysis. An improved e-ecology platform that leverages these tools is needed for ecologists to acquire and understand large spatiotemporal datasets, and thus inform knowledge gaps in environmental policy-making. Developing the next generation of e-ecology tools will require synergistic partnerships between academia and industry and significant investment in a cross-disciplinary scientific consortia. Safe fecal sludge management (FSM) - the hygienic emptying, transport, and treatment for reuse or disposal of fecal sludge - is an essential part of safely managed sanitation, especially in towns and cities in low- and middle-income countries with limited sewer coverage. The need for safe and affordable FSM services has become more acute as cities grow and densify. Hygienic pit-emptying uses equipment that limits direct human exposure with fecal sludge and hygienic transport conveys fecal sludge offsite for treatment. We evaluated whether a program of on-site sanitation infrastructure upgrades and FSM capacity development in urban Maputo, Mozambique resulted in more hygienic pit-emptying and safe transportation of fecal sludge. We compared reported emptying practices among multi-household compounds receiving sanitation upgrades with control compounds, both from the Maputo Sanitation (MapSan) trial at 24-36 months after the intervention. Intervention compounds (comprising 1-40 households, median = 3) received a subsidized pour-flush latrine to septic tank system that replaced an existing shared latrine; control compounds continued using existing shared latrines. We surveyed compound residents and analyzed available municipal data on FSM in the city. Due to the recent construction of the intervention, emptying was more frequent in control compounds 5.6% (15/270) of intervention compounds and 30% (74/247) of controls had emptied their on-site sanitation system in the previous year. Among those compounds which had emptied a sanitation facility in the previous year, intervention compounds were 3.8 (95% CI 1.4, 10) times more likely to have to done so hygienically. Results suggest that the construction of subsidized pour-flush sanitation systems increased hygienic emptying of fecal sludge in this setting. Further gains in hygienic emptying in urban Maputo may be limited by affordability and physical accessibility. A novel guanine-inspired 2-hydrazinyl-4(3H)-quinazolinone derivative (HL) has been synthesized and characterized. The reaction of HL with Cu(II) in a 11 ML ratio and with Cu(II), Ni(II) and Zn(II) in a 12 ML ratio resulted in the formation of complexes, [Cu(L)(H2O)2](NO3), 1 and [M(L)2] (M = Cu for 2, Ni for 3 and Zn for 4), respectively. In all these complexes, the ligand L is tridentately bound to the corresponding metal. The affinity of the complexes for calf-thymus DNA was examined by diverse techniques and the complexes can intercalate between the DNA-bases. The cleavage ability of the complexes towards supercoiled circular pBR322 plasmid DNA was examined via agarose gel electrophoresis experiments in the absence or presence of UVA, UVB or visible light and the DNA-cleavage was found to depend on the concentration and light wavelength used. The binding of the complexes for bovine and human serum albumins was also investigated in order to determine the binding constants and the binding subdomain. The scavenging activity of the compounds was evaluated towards free radicals 1,1-diphenyl-picrylhydrazyl and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid). Naphthalene sulfonic acids (NSAs) are used as additives in lubricants, dyes, and greases and commonly act as surfactants in many industrial processes. The calcium salt of dinonyl NSA (calcium dinonylnaphthalenesulfonate; CaDNS) is listed among thousands of chemicals identified as priorities for assessment by the Government of Canada's Chemical Management Plan due to the limited toxicity data. The purpose of this study was two-fold 1) to establish the toxicity of CaDNS to Western clawed frog (Silurana tropicalis) embryos and 2) to assess the sub-lethal effects and mechanisms of toxicity of CaDNS in amphibians through targeted gene expression and metabolite analyses. Frog embryos were exposed to water overlying sand spiked with a range of concentrations of CaDNS (17-1393 μg/g) over a 72-h period. Results indicated significantly higher mortality and presence of malformations in frog larvae exposed to over 672 μg/g CaDNS in the sand (14 ng/mL CaDNS in the water) compared to control treatments. An overall decrease in the glutathione redox cycle was observed, including decreases in relative mRNA levels of enzymes (glutathione S-transferase (gst), glutathione reductase (gsr), glutathione peroxidase (gpx)) and decreases in the glutathione (GSH) and glutathione disulfide (GSSG) metabolite concentrations.
