Notes

A quick review of case study regarding time-series data coming from biologging scientific studies.
Besides incineration, adsorption of PFAS on granulated activated carbon is one of the most widely used technology albeit with poor adsorption, often requiring very large downstream filtration systems. Finally, the application of functional precipitation agents using commercially available cationic surfactants is a novel approach (PerfluorAd® process) that enables the effective precipitation of PFAS from the spent fire-extinguishing waters. Hence, the goal of this study was to investigate the environmental impacts emanating from the proper treatment of spent fire-extinguishing water with the aforementioned three end-of-life treatment scenarios. A life cycle assessment was conducted for this purpose. The results show that the PerFluorAd® process outperforms the other two treatment technologies across all environmental impact categories except for ozone depletion.

Gene mutations are expected to provide novel biomarkers for urinary BC diagnosis. So far, evidence on urinary BC mutation markers has not proven sufficient to be adopted by clinical guidelines. In this systematic review, diagnostic accuracy of urinary mutation analysis is separately assessed for primary BC diagnosis (BC detection) and for follow-up of BC patients (BC surveillance). Methods A literature search (PubMed, Embase.com and Wiley/Cochrane Library) and systematic review was performed up to October 31, 2019. As studies were too heterogeneous, no quantitative analysis could be performed. Results In total, 25 studies were summarized by qualitative analysis. For BC detection, diagnostic accuracy differed considerably for single mutation markers (sensitivity 1% ─ 85%, specificity 84% ─ 100%), and for marker panels (sensitivity 50% - 94%, specificity 43% - 97%). Similarly, for BC surveillance, diagnostic accuracy was highly variable for single mutation markers (sensitivity 0% ─ 85%, specificity 66% ─ 100%), and for marker panels (sensitivity 51% - 84%, specificity 66% - 96%). Conclusion Urinary mutation analysis showed to be a promising diagnostic tool for non-invasive BC diagnosis. Nonetheless, we observed substantial differences in diagnostic accuracy of urinary BC mutation markers among publications. To translate the data summarized in the present review to future clinical practice, heterogeneity in research design, BC population, mutation analysis technique and urinary DNA should be considered. Eventual clinical implementation of urinary BC mutation markers can only be achieved by collecting more and stronger evidence. Combining different molecular assays might overcome current shortcomings of urinary mutation analysis.Infochemicals act as inter- or intraspecific messengers. Literature suggests complex interactions between infochemicals (mainly predator cues) and chemical (e.g., pesticide) effects, with their direction and magnitude depending on the cues' origin, pesticide identity and test species. With the present study we assessed the impact of alarm cues alone and in combination with the neonicotinoid insecticide thiacloprid on leaf consumption, predation on Baetis nymphs and dry weight of the amphipod Gammarus fossarum. Alarm cues (ground gammarids) and thiacloprid alone decreased gammarids' leaf consumption with increasing intensities. At a defined alarm cue intensity, which alone did not cause a significant reduction in gammarids' feeding, thiacloprid-induced feeding effects were additive. During an experiment targeting gammarids' predation on Baetis nymphs (120h), thiacloprid and alarm cues alone did increase and reduce predation significantly, respectively. Moreover, alarm cues led to a lower final gammarid dry weight. However, alarm cues did not affect response variables during a second predation experiment performed at a higher thiacloprid concentration (2 vs. 0.75 µg/L). This discrepancy in alarm cues' effects either highlights a varying susceptibility of the test species to these cues among experiments or that cue quality is fluctuating. Thus, the present work highlights a considerable variability in the individual and interactive effects of infochemicals and chemical stressors on aquatic biota, an insight relevant in the assessment of multiple stressors.

We conduct a unique investigation by using a controlled 3D in vitro cell model to mimic the bone microenvironment in microgravity aboard the SpaceX Dragon cargo ferry to the ISS. Osteoblasts (OBs), osteoclasts (OCs), and endothelial cells (ECs), seeded on Skelite discs, were cultured w/ or w/o rec-Irisin and exposed to 14 days of microgravity in the eOSTEO hardware. Gene expression analysis was assessed, and results were compared to ground controls treated within identical payloads. Our results show that the microgravity-induced downregulation of mRNA levels of genes encoding for OB key transcription factors (Atf4 -75%, P less then .01; RunX2 -87%, P less then .001, Osterix -95%, P less then .05 vs ground) and proteins (Collagen I -84%, P less then .05; Osteoprotegerin -94%, P less then .05) were prevented by irisin. Despite it was not effective in preventing Trap and Cathepsin K mRNA increase, irisin induced a 2.8-fold increase of Osteoprotegerin (P less then .05) that might act for reducing osteoclastogenesis in microgravity. Our results provide evidence that irisin supports OB differentiation and activity in microgravity and it might represent a countermeasure to prevent bone loss in astronauts.M yrtucomvalones D-F ( 1 - 3 ), three new triketone-phloroglucinol-triketone adduct s, and three known ones ( 4 - 6 ) were obtained from Myrtus communis 'Variegata'. Compound 1 is a pair of enantiomers which was further resolved into (+)- 1 and (-)- 1 by chiral HPLC. Their structures and complete stereochemistry were established from interpretation of NMR and crystallographic data and chemical calculations. Compounds 3 , 5 and 6 showed significant antibacterial activities.This study describes and illustrates the jaws, teeth, and tooth microstructure of the Prickly Dogfish Oxynotus bruniensis. Detailed accounts of the dental morphology of O. bruniensis are rare and have not addressed the tissue arrangement or microstructure of the teeth. These features are documented and discussed in the contexts of interspecific comparisons with other elasmobranchs and the dietary specialization of O. bruniensis. The overall tooth morphology of O. bruniensis is similar to those of other closely related members in the order Squaliformes, as is the tissue arrangement, or histotype. Oxynotus bruniensis exhibits a simplified enameloid microstructure, which we compare with previously documented enameloid microstructures of other elasmobranchs. Though subtle interspecific differences in dental characters are documented, neither overall tooth morphology nor histotype and microstructure are unique to O. bruniensis. We conclude that in the case of O. bruniensis, dietary specialization is facilitated by behavioral rather than morphological specialization.The Cr/SiO2 Phillips catalyst has taken a central role in ethylene polymerization ever since its discovery. This catalyst is unique compared to other polymerization catalysts, since it is active without the addition of a metal-alkyl co-catalyst. However, metal-alkyls can be added for scavenging poisons, enhancing the catalyst activity, reducing the induction period and altering polymer characteristics. Despite extensive research into the working state of the catalyst, still no consensus has been reached. Here, we show that by varying the type of metal-alkyl co-catalyst and its amount, the Cr redox chemistry can be tailored, resulting in distinct catalyst activities, induction periods, and polymer characteristics. We have used UV-Vis-NIR diffuse reflectance spectroscopy for studying the Cr oxidation state during the reduction by tri-ethyl borane (TEB) or tri-ethyl aluminum (TEAl) and during subsequent ethylene polymerization. The results showed that TEB primarily acts as a reductant and reduces Cr 6+ with subsequent ethylene polymerization resulting in rapid polyethylene formation. TEAl, on the other hand, generates a different variety of reduced Cr species as well as enhances the reducibility by ethylene, while being highly active polyethylene formation. Our results demonstrate the possibility of controlling the reduction chemistry by adding the proper amount and type of metal-alkyl for obtaining desired catalyst activities and tailored polyethylene characteristics.In this study, the nondestructive differentiation of individual white polyester clothing fibers was accomplished via synchrotron radiation microbeam X-ray fluorescence (SR-μ-XRF) analysis. SR-μ-XRF with vertical focusing is a useful nondestructive method for the analysis of a single polyester clothing fiber. Kirkpatrick-Baez (KB) mirror was used to vertically focus 20 keV X-rays for the analysis of 22 individual white polyester fibers taken from clothing commonly sold in Japan. FR 180204 price SR-μ-XRF with a vertical focused 2 μm (V) × 300 μm (H) beam was approximately 12.8 times more sensitive than SR-XRF with an unfocused 300 μm (V) × 300 μm (H) beam for the detection of elements in single fibers. The minimum detection limits (MDLs) of the SR-μ-XRF method were 8.15 ppm for Cl and 0.06 ppm for Br. In addition to Ti in TiO2 delustering agents, Zr and Nb impurities in the delustering agents were detected in individual fibers. Sb from a polymerization catalyst and Co from a transesterification catalyst were also detected in individual fibers. Comparing the Ti Kβ /Sb Lα,β and Zr Kα /Nb Kα X-ray intensity ratios was a useful way to distinguish individual clothing fibers, and 98% of the fibers were differentiated when additional trace elements were used as discrimination indicators.Objectives Numerous authors have expressed their interest in adjustment and social support in the context of cancer. However, none of the previous studies has directly examined the models describing the links between daily social support and adjustment fluctuation, particularly at the relational level. This study aimed to verify the additive and buffering models of daily received support regarding the relational level of patient-caregiver relationship, that is, the relationship-related stress and relationship satisfaction following hematopoietic cell transplantation (HCT). Methods Two hundred patient-caregiver dyads participated in a 28-day diary study that was started on the first day after post-HCT discharge. The participants rated the extent of daily relationship-related stress, relationship satisfaction, and received support every evening during the study. The analyses were based on the actor-partner interdependence moderation model. Results Daily deviations in received support were directly associated with concurrent and lagged daily deviations in relationship satisfaction, regardless of relationship-related stress level in both patients and caregivers.
