The overall territorial carbon footprint of the wastewater treatment service was also quantified to provide evidence-based decision support system (DSS) and prepare systemic mitigation strategies.Gadolinium-based contrast agents (GBCAs) are frequently used for magnetic resonance imaging to improve image contrast. These inert complexes are excreted unmetabolized from the human body and pass through wastewater treatment plants almost unaffected, leading to a significant release of anthropogenic Gd into the environment. However, long-term ecotoxicological effects of GBCAs are mainly unknown and thus powerful methods of speciation analysis are required to monitor their distribution and fate in aquatic systems. In this work, a rapid and efficient monitoring method was developed utilizing a fully automated single platform system for total metal analysis and syringe-driven chromatography in combination with inductively coupled plasma-mass spectrometry (ICP-MS). An anion-exchange chromatography (IC) method was developed and applied to achieve a rapid separation and sensitive detection of the five complexes Gd-HP-DO3A, Gd-BT-DO3A, Gd-DOTA, Gd-DTPA, and Gd-BOPTA that are commonly administered in the European Union. Furthermore, the use of an automated inline-dilution function allowed a fast-external calibration from single stock standards. A chromatographic run time of less than 2 min and species-specific detection limits between 11 and 19 pmol L-1 on a quadrupole ICP-MS proved to be competitive compared to previously published methods, but without the use of aerosol desolvation and/or sector field ICP-MS to enhance sensitivity. The automated IC-ICP-MS method was applied for quantitative GBCA monitoring in a multitude of surface water samples that were obtained in the German state of North Rhine-Westphalia. The complexes Gd-HP-DO3A, Gd-BT-DO3A, and Gd-DOTA, were detected and quantified. In addition, the occurrence of an unidentified Gd species was observed for one of the sampled river systems.Salivary hormone analyses provide a useful alternative to fecal and urinary hormone analyses in non-invasive studies of behavioral endocrinology. Here, we use saliva to assess cortisol levels in a wild population of spotted hyenas (Crocuta crocuta), a gregarious carnivore living in complex social groups. CP690550 We first describe a novel, non-invasive method of collecting saliva from juvenile hyenas and validate a salivary cortisol assay for use in this species. We then analyze over 260 saliva samples collected from nearly 70 juveniles to investigate the relationships between cortisol and temporal and social variables in these animals. We obtain some evidence of a bimodal daily rhythm with salivary cortisol concentrations dropping around dawn and dusk, times at which cub activity levels are changing substantially. We also find that dominant littermates have lower cortisol than singleton juveniles, but that cortisol does not vary with age, sex, or maternal social rank. Finally, we examine how social behaviors such as aggression or play affect salivary cortisol concentrations. We find that inflicting aggression on others was associated with lower cortisol concentrations. We hope that the detailed description of our methods provides wildlife researchers with the tools to measure salivary cortisol in other wild carnivores.Rubusoside, which is used as a natural sweetener or a solubilizing agent for water-insoluble functional materials, is currently expensive to produce owing to the high cost of the membrane-based technologies needed for its extraction and purification from the sweet tea plant (Rubus suavissimus S. Lee). Therefore, this study was carried out to screen for lactic acid bacteria that possess enzymes capable of bio-transforming stevioside into rubusoside. Subsequently, one such rubusoside-producing enzyme was isolated from Lactobacillus plantarum GS100. Located on the bacterial cell surface, this enzyme was stable at pH 4.5-6.5 and 30-40 °C, and it produced rubusoside as a major product through its stevioside-hydrolyzing activity. Importantly, the enzyme showed higher β-glucosidase activity toward the β-linked glucosidic bond of stevioside than toward other β-linked glucobioses. Under optimal conditions, 70 U/L of the rubusoside-producing enzyme could produce 69.03 mM rubusoside from 190 mM stevioside. The β-glucosidase activity on the cell surface was high at 35 h of culture. This is the first report detailing the production of rubusoside from stevioside by an enzyme derived from a food-grade lactic acid bacterium. The application of this β-glucosidase could greatly reduce the cost of rubusoside production, hence benefiting all industries that use this natural product.The field of biofabrication continues to progress, offering higher levels of spatial control, reproducibility, and functionality. However, we remain far from recapitulating what nature has achieved. Biological systems such as tissues and organs are assembled from the bottom-up through coordinated supramolecular and cellular processes that result in their remarkable structures and functionalities. In this perspective, we propose that incorporating such biological assembling mechanisms within fabrication techniques, offers an opportunity to push the boundaries of biofabrication. We dissect these mechanisms into distinct biological organization principles (BOPs) including self-assembly, compartmentalization, diffusion-reaction, disorder-to-order transitions, and out-of-equilibrium processes. link2 We highlight recent work demonstrating the viability and potential of these approaches to enhance scalability, reproducibility, vascularization, and biomimicry; as well as current challenges to overcome.
Patients with central nervous system malignancies have limited representation in studies evaluating DOACs for VTE treatment. This study evaluated the safety and efficacy of DOACs in comparison with LMWH for cancer-associated VTE in patients with primary brain tumors or secondary brain metastases.
In this multicenter, retrospective cohort study, adult patients with a diagnosis of primary brain tumor or secondary brain metastases who received either a DOAC or LMWH for treatment of cancer-associated VTE were evaluated. The primary outcome was the cumulative incidence of any intracranial hemorrhage within a 6-month period following the initiation of anticoagulation. Secondary outcomes included the cumulative incidence of any bleeding event, and recurrent VTE events.
Between January 1, 2012 and October 9, 2019, one-hundred eleven patients met inclusion criteria. The 6-month cumulative incidence of intracranial hemorrhage was 4.3% (95% CI, 0.74-13.2%) in the DOAC group, compared to 5.9% (95% CI, 1.5-14.9%) in the LMWH group (p=0.61). The 6-month cumulative incidence of bleeding events was 14.3% (95% CI, 6.2-25.8%) in the DOAC group, compared to 27.8% (95% CI, 15.5-41.6%) in the LMWH group (p=0.10). The 6-month cumulative incidence of recurrent VTE events was 5.6% in the DOAC group (95% CI, 1.5-14.2%), compared to 6.6% in the LMWH group (95% CI, 1.7-16.5%) (p=0.96). No differences were found with respect to other secondary outcomes.
There were no significant differences in bleeding or recurrent VTE events between DOACs and LMWH. These findings suggest DOACs may be safe and effective for VTE treatment in this patient population.

Interpersonal entrainment phenomena, such as dance, involve multiple body parts and movement directions. Along with being multidimensional, dance movement interaction is plurifrequential, since it can occur at different frequencies simultaneously. Moreover, it is prone to nonstationarity, due to, for instance, displacements around the dance floor. Various methodological approaches have been adopted for the study of human entrainment, but only spectrogram-based techniques allow for an integral analysis thereof. This article proposes an alternative approach based upon the cross-wavelet transform, a state-of-the-art technique for nonstationary and plurifrequential analysis of univariate interaction. The presented approach generalizes the cross-wavelet transform to multidimensional signals. It allows to identify, for different frequencies of movement, estimates of interaction and leader-follower dynamics across body parts and movement directions. Further, the generalized cross-wavelet transform can be used to quantify the frequency-wise contribution of individual body parts and movement directions to overall movement synchrony. Since both in- and anti-phase relationships are dominant modes of coordination, the proposed implementation ignores whether movements are identical or opposite in phase. The article provides a thorough mathematical description of the method and includes proofs of its invariance under translation, rotation, and reflection. Finally, its properties and performance are illustrated via four examples using simulated data and behavioral data collected through a mirror game task and a free dance movement task.Nontargeted analysis based on mass spectrometry is a rising practice in environmental monitoring for identifying contaminants of emerging concern. Nontargeted analysis performed using comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC×GC/TOF-MS) generates large numbers of possible analytes. Moreover, the default spectral library similarity score-based search algorithm used by LECO® ChromaTOF® does not ensure that high similarity scores result in correct library matches. Therefore, an additional manual screening is necessary, but leads to human errors especially when dealing with large amounts of data. To improve the speed and accuracy of the chemical identification, we developed CINeMA.py (Classification Is Never Manual Again). This programming suite automates GC×GC/TOF-MS data interpretation by determining the confidence of a match between the observed analyte mass spectrum and the LECO® ChromaTOF® software generated library hit from the NIST Electron Ionizatiol data analysis required hours or days to complete. link3 Our methods were also able to detect high confidence matches missed during the manual review. Overall, CINeMA.py provides users with a powerful suite of tools that should significantly speed-up data analysis while reducing the possibilities of manual errors and discrepancies among users, and can be applicable to other GC/EI-MS instrument based nontargeted analysis.Cyanuric chloride and 4,4'-diamino-p-terphenyl were adopted as monomers to synthesize poly (4,4'-diamino-p-terphenyl-triazine) (PDT) covalent organic polymer. PDT coated stir bar was prepared and evaluated for the extraction of five phthalate esters (PAEs) with relatively lower logP values (2.7-4.9), including diethyl phthalate, diallyl phthalate, dipropyl phthalate, benzylbutyl phthalate and dibutyl phthalate. It exhibited higher extraction recovery (> 65%) and faster extraction kinetics (50 min vs 240 min) for target PAEs over commercial polydimethylsiloxane coated stir bar. Based on the superior performance, PDT coated stir bar sorptive extraction was combined with high-performance liquid chromatography-diode array detection for trace analysis of five PAEs plasticizers. The limits of detection for target PAEs were 0.04-0.27 μg/L, with the enrichment factors of 54-80-fold. The potential of the method was demonstrated by detecting five target PAEs in Chinese liquor and mineral water samples. No target analytes were detected in Chinese liquor sample, and recoveries of 85.
