Authors: Khlyustova Anna , Sirotkin Nikolay , Titov Valery 
Published: September 2019

AbstractBACKGROUNDThis work focuses on removing metal ions (Fe3+, Cu2+, and Zn2+) from aqueous solutions and real wastewater by underwater plasma.RESULTSResults show that the joint presence of Fe3+, Cu2+, and Zn2+ are needed for effective precipitation of these ions from aqueous solutions. The short‐time underwater plasma treatment leads to more effective removal of metal ions from real wastewater compared to treatment facilities of a factory.CONCLUSIONSRemoving metal ions from aqueous solutions of their mixture by underwater plasma occurs via formation of non‐dissolved substances on the base of metal oxide/hydroxide. Efficient removal of metal ions from real wastewater allows the creation of a prototype setup as one of the blocks of treatment facilities at a chemical factory. © 2019 Society of Chemical Industry

BackgroundCerebral intravoxel incoherent motion (IVIM) imaging assumes two components. However, more compartments are likely present in pathologic tissue. We hypothesized that spectral analysis using a nonnegative least‐squares (NNLS) approach can detect an additional, intermediate diffusion component, distinct from the parenchymal and microvascular components, in lesion‐prone regions.PurposeTo investigate the presence of this intermediate diffusion component and its relation with cerebral small vessel disease (cSVD)‐related lesions.Study TypeProspective cross‐sectional study.PopulationPatients with cSVD (n = 69, median age 69.8) and controls (n = 39, median age 68.9).Field Strength/SequenceWhole‐brain inversion recovery IVIM acquisition at 3.0T.AssessmentEnlarged perivascular spaces (PVS) were rated by three raters. White matter hyperintensities (WMH) were identified on a fluid attenuated inversion recovery (FLAIR) image using a semiautomated algorithm.Statistical TestsRelations between IVIM measures and cSVD‐related lesions were studied using the Spearman's rank order correlation.ResultsNNLS yielded diffusion spectra from which the intermediate volume fraction fint was apparent between parenchymal diffusion and microvasular pseudodiffusion. WMH volume and the extent of MRI‐visible enlarged PVS in the basal ganglia (BG) and centrum semiovale (CSO) were correlated with fint in the WMHs, BG, and CSO, respectively. fint was 4.2 ± 1.7%, 7.0 ± 4.1% and 13.6 ± 7.7% in BG and 3.9 ± 1.3%, 4.4 ± 1.4% and 4.5 ± 1.2% in CSO for the groups with low, moderate, and high number of enlarged PVS, respectively, and increased with the extent of enlarged PVS (BG: r = 0.49, P < 0.01; CSO: r = 0.23, P = 0.02). fint in the WMHs was 27.1 ± 13.1%, and increased with the WMH volume (r = 0.57, P < 0.01).Data ConclusionWe revealed the presence of an intermediate diffusion component in lesion‐prone regions of cSVD and demonstrated its relation with enlarged PVS and WMHs. In tissue with these lesions, tissue degeneration or perivascular edema can lead to more freely diffusing interstitial fluid contributing to fint.Level of Evidence: 2Technical Efficacy: Stage 2J.

Published: September 2019

AbstractBACKGROUNDThe sunflower oil industry produces a large amount of waste that is not currently commercially exploited, as in the case of oil‐tank settlings. The recovery of a high value‐added by‐product, such as sunflower wax, would increase the commercial value of this waste. In this original research paper, a method that allows the recovery and purification of this by‐product was developed. The wax was characterized and its potential use as an organogelator agent was investigated.RESULTSThe waste sample was composed of 45.1% oily material, 16.9% of this being impure waxes. Purification was performed through two different methods, obtaining three waxes with different degrees of purity. All the waxes were composed of wax esters with a range of 40–60 carbon atoms, exhibiting traces of carotenes, free fatty acids, and free fatty alcohols. The presence of phospholipids was observed in two of them. The third wax presented a higher total wax ester content and physicochemical characteristics (color and thermal behavior) similar to those of commercial sunflower waxes, and was the most efficient organogelator agent, requiring only a small amount of wax (1.5%) to structure high oleic sunflower oil.CONCLUSIONIt was verified that sunflower wax could be recovered from oil‐tank settlings. A purification method that allowed sunflower wax with similar physicochemical properties to those of commercial waxes to be obtained was also developed. The purified waxes were capable of structuring high oleic sunflower oil. © 2019 Society of Chemical Industry

AbstractPropolis is a resinous substance composed of a mixture of different plant parts and molecules secreted by bees. Chemically, it is defined as a complex matrix containing biologically active molecules with antibacterial, antifungal, antiviral, antiparasitic, hepatoprotective, and immunomodulatory activities. It is widely employed in cosmetic formulations and pharmaceutical products and is one of the most widely used natural products. However, the effects and strength of these biological activities depend on the chemical profile and composition of each propolis type. This composition is associated with the diversity of local flora, the place and period of collection, and the genetics of the bees. In this context, the objective of this review was to investigate the biological, chemical, and microbiological properties of propolis. A technological prospection was also performed on patents for products designed to be used in animal health. Our investigation shows that the literature contains diverse studies dedicated to comparing and describing the composition and therapeutic properties of propolis. These studies demonstrate the potential biological use of propolis in veterinary medicine, showing the applications of propolis extracts in different formulations. However, there are a low number of propolis‐based veterinary products with a registered patent. Thus, the development of products based on propolis is a promising market to be exploited. © 2019 Society of Chemical Industry

AbstractBackgroundThe use of radiation therapy in the treatment of retroperitoneal sarcomas has increased in recent years. Its impact on survival and recurrence is unclear.MethodsA retrospective propensity score matched (PSM) analysis of patients with primary retroperitoneal soft tissue sarcomas, who underwent resection from 2000 to 2016 at eight institutions of the US Sarcoma Collaborative, was performed. Patients with metastatic disease, desmoid tumors, and palliative resections were excluded.ResultsTotal 425 patients were included, 56 in the neoadjuvant radiation group (neo‐RT), 75 in the adjuvant radiation group (adj‐RT), and 294 in the no radiotherapy group (no‐RT). Median age was 59.5 years, 186 (43.8%) were male with a median follow up of 31.4 months. R0 and R1 resection was achieved in 253 (61.1%) and 143 (34.5%), respectively. Overall 1:1 match of 46 adj‐RT and 59 neo‐RT patients was performed using histology, sex, age, race, functional status, tumor size, grade, resection status, and chemotherapy. Unadjusted recurrence‐free survival (RFS) was 35.9 months (no‐RT) vs 33.5 months (neo‐RT) and 27.2 months (adj‐RT), P = .43 and P = .84, respectively. In the PSM, RFS was 17.6 months (no‐RT) vs 33.9 months (neo‐RT), P = .28 and 19 months (no‐RT) vs 27.2 months (adj‐RT), P = .1.ConclusionsUse of radiotherapy, both in adjuvent or neoadjuvent setting, was not associated with improved survival or reduced recurrence rate.

AbstractExposure to 2012's Hurricane Sandy differed by community across New York City and nearby Long Island, and the differential impact of exposure on mental health concerns must be studied to enhance resilience in vulnerable communities. We assessed the association between self‐reported Hurricane Sandy exposure and subsequent posttraumatic stress disorder (PTSD) symptoms, obtained through validated questionnaires completed by residents of lower Manhattan (n = 1,134), Queens/Long Island (LI)/Staten Island (SI; n = 622), and the Rockaways (n = 1,011); mean assessment times were 7, 14, and 32 months post‐Sandy, respectively. The median number of hurricane exposures was similar for all communities; however, Rockaways residents had a higher proportion of likely PTSD symptoms (18.8%) compared to lower Manhattan (8.0%) and Queens/LI/SI residents (5.8%). Regarding likely PTSD, there was significant interaction between total hurricane exposure and community, p = .002, and flooding and community, p = .040. Number of hurricane exposures was associated with higher odds of likely PTSD in Queens/LI/SI, AOR = 1.61, 95% CI [1.34, 1.94]; lower Manhattan, AOR = 1.43, 95% CI [1.28, 1.59]; and the Rockaways, AOR = 1.25, 95% CI [1.16, 1.35]. Flooding was associated with increased odds of likely PTSD in the Rockaways, AOR = 1.65, 95% CI [1.01, 2.69]; and Queens/LI/SI, AOR = 3.29, 95% CI [1.08, 10.00]. This study emphasizes the differential impact of hurricane exposure on subsequent PTSD symptoms in three communities affected by Hurricane Sandy. Future preparedness and recovery efforts must understand community correlates of mental health concerns to promote resilience in vulnerable communities.

ObjectivesTo determine whether adjunctive surgical techniques could improve access of instruments provided by the endoscopic prelacrimal recess approach to the anatomical boundaries of the maxillary sinus, and pterygopalatine and infratemporal fossa.MethodsTen fresh‐frozen adult cadaver heads were utilized. The anatomical areas of interest were fixed, bony boundaries of the maxillary sinus, infratemporal fossa, and pterygopalatine fossa: alveolar recess (AR), zygomatic recess (ZR), perpendicular plate of the palatine bone (PB), ascending ramus of mandible (RM), floor of the orbit medial and lateral to infraorbital nerve (M‐ION and L‐ION, respectively). Access to the areas were compared using standard sinus surgery instruments (straight and 45° forceps) introduced via the prelacrimal recess approach, trans‐septal window and canine fossa puncture.ResultsThe prelacrimal recess approach successfully provided access to the PB and M‐ION in >90% of dissections when using both the straight and 45° forceps. With the straight forceps, the ability to successfully access to the AR and ZR was the lowest at 50% and 35% respectively, although improving to 75% and 60% respectively with the 45° forceps. Access to the AR, ZR, and L‐ION improved significantly when the 45° forceps was introduced through the trans‐septal window. Frequency of access to the RM when either instruments when introduced through the canine fossa puncture was no greater than 60% of the dissections.ConclusionsThe addition of a small trans‐septal window for instruments significantly improved access of the prelacrimal recess approach especially to the orbital floor, lateral margins of the maxillary sinus, and retromaxillary space.Level of Evidence4Laryngoscope, 130: 1857–1863, 2020
Patterns and processes of free‐living and particle‐associated bacterioplankton and archaeaplankton communities in a subtropical river‐bay system in South China

AbstractFree‐living and particle‐associated microbial communities play critical roles in nutrient cycles in aquatic systems. However, little is known about their assembly process, function, and interactions. Here, by using 16S rRNA gene amplicon sequencing of size‐fractionated samples collected during the wet and dry seasons, we investigated the assembly processes and co‐occurrence patterns of bacterial and archaeal communities in the Shenzhen River‐Bay system, South China. The bacterial and archaeal communities showed specific distribution patterns according to the size fraction (free‐living vs. particle‐associated), habitat (river vs. estuary), and seasonality (wet vs. dry season). Neutral modeling revealed that the stochastic pattern was more pronounced for bacteria than archaea, although both deterministic and stochastic processes significantly influenced the assembly of bacterial and archaeal communities. Homogeneous selection had a relatively higher importance in structuring bacterioplankton in free‐living fractions, while this process was more important in structuring archaeaplankton in particle‐associated fractions. Aquatic microbial community composition and assembly processes were most strongly associated with salinity and water temperature. Network analysis for each size fraction of the plankton revealed higher connectivity in the particle‐associated communities than the free‐living communities for intra‐bacteria, inter‐bacteria/archaea, and intra‐archaea associations, accordingly, when nonlinear associations were considered. These findings expand the current understanding of the ecological mechanisms and Archaea‐Bacteria interactions, underlying the size‐fractionated plankton dynamics in the river‐bay system.
Morphology and photosynthetic response of the kelp Ecklonia radiata across a turbidity gradient

Published: September 2019

AbstractIncreasing turbidity in coastal waters reduces benthic irradiance levels and consequently poses a fundamental threat to benthic primary producers and the food webs they support. It is therefore necessary to better understand how important primary producers, such as kelp, can adapt both physiologically and morphologically to these declining light conditions. This study examines how variation in turbidity influences the morphology of the kelp Ecklonia radiata, and how this relates to photosynthetic performance, by measuring multiple morphological characteristics, photosynthesis‐irradiance response, and photosynthetic pigments in adult kelp across a large‐scale turbidity gradient. Kelp morphology was strongly related to variation in benthic irradiance among sites, but this was not consistent with morphological acclimation. Kelp at the most turbid sites had short stipes (< 0.4 m) and lower surface area to volume ratios (SA:V) than kelp at moderate to high‐light sites, which had long stipes (~ 1 m) and high SA:V. Photosynthetic parameters and pigment content also varied considerably in relation to benthic irradiance, with increased photosynthetic efficiency and pigment content at low‐light sites. However, maximum rates of photosynthesis were highest at high‐light sites and strongly positively related to higher SA:V of kelp at these sites. These results demonstrate that while physiological adaptation may increase photosynthetic efficiency at low‐light sites, maximum photosynthetic output is strongly related to thallus morphology rather than cellular acclimation. This suggests that the large‐scale variation in kelp morphology observed across the turbidity gradient likely has important consequences for overall primary production as well as other important ecosystem functions.
Disturbance pattern recognition based on an ALSTM in a long‐distance φ‐OTDR sensing system
Authors: Chen Xue , Xu Chengjin 
Published: September 2019

AbstractIn this article, a new pattern recognition method for disturbance signals detected by phase‐sensitive optical time domain reflectometry (φ‐OTDR) distributed optical fiber sensing systems is proposed. Currently, most of the disturbance signal recognition methods for φ‐OTDR exploit the global features of disturbance signals as the basis of classification, neglect the local details of disturbance signals, and thus have poor performances on long‐distance monitoring tasks. In the method proposed in this article, an adaptive denoising method based on spectral subtraction is utilized to enhance signal features. For each frame of disturbance signals, Mel‐frequency cepstral coefficients are extracted as frequency‐domain features, while short‐time energy ratio and short‐time level crossing rate are extracted as time‐domain features. An attention‐based long short‐term memory network is exploited as a classifier to recognize different types of disturbance signals. Experiments show the proposed disturbance recognition method can achieve a classification accuracy of 94.3% with five typical disturbances, namely, walking, digging, vehicle‐passing, climbing, and heavy rain, at ranges of up to 50 km.

AbstractAimsTo assess the predictive values of six urinary markers (nerve growth factor [NGF], brain‐derived neurotrophic factor [BDNF], matrix metalloproteinase 2 [MMP‐2], tissue inhibitor metalloproteinase 2 [TIMP‐2], transformation growth factor β‐1 [TGF‐B1], and prostaglandin 2 [PGE2]) for adverse urodynamic features and for upper urinary tract damage in adult patients with spina bifida.Materials and methodsA single‐center prospective trial was conducted from March 2015 to March 2017 including all consecutive adult patients with spina bifida seen for urodynamic testing. The urine was collected and stored at −80°C. A urodynamic and an upper urinary tract were systematically performed. At the end of the inclusion period, urines were defrosted and urinary nerve growth factor, BDNF, TIMP‐2, and TGF‐B1 were assessed using validated ELISA kits. The urinary markers levels were adjusted on the urinary creatinine level. Urinary MMP‐2 levels were assessed by zymography.ResultsFourty patients were included. Only TIMP‐2 and MMP‐2 were significantly associated with poor bladder compliance (P = .043 and P = .039, respectively). TIMP‐2 was also the only urinary marker significantly associated with upper urinary tract damage on imaging (OR = 19.81; P = .02). Of all urodynamic parameters, bladder compliance and maximum detrusor pressure were the only ones associated with upper urinary tract damage on imaging (P = .01 and P = .02), The diagnostic performances of urinary TIMP‐2 for upper urinary tract damage were slightly superior to PdetMax and bladder compliance with an area under the curve of 0.72.ConclusionUrinary TIMP‐2 and MMP‐2 were significantly associated with poor bladder compliance and urinary TIMP‐2 was significantly associated with upper urinary tract damage. These findings support a pathophysiological role of extracellular matrix remodeling in poor bladder compliance of adult patients with spina bifida.

Published: September 2019

ABSTRACTThe supplemental activator and reducing agent (SARA) atom transfer radical polymerization (ATRP) mediated by Na2S2O4 in the presence of air, without external deoxygenation or additional oxygen scavengers, is reported for several vinyl monomers: methyl acrylate (MA), n‐butyl acrylate (n‐BA), methyl methacrylate (MMA), 2‐(dimethylamino)ethyl methacrylate (DMAEMA), poly(ethylene glycol) methyl ether acrylate (OEOA), and styrene (Sty). The polymerizations can be conducted in aqueous medium or using organic/water mixtures as solvent, with low concentration of copper, near room temperature. In the absence of any external deoxygenation, several well‐defined homopolymers and block copolymers were obtained (Ð < 1.3). The evolution of the oxygen concentration during the polymerizations was monitored with an optical oxygen sensor. The consumption of oxygen prior polymerization in ethanol/water mixtures was attributed to the combined presence of Na2S2O4 and alkyl halide initiator, which led to a lower initiation efficiency (Ieff). This could be overcome by decreasing the headspace volume of the reaction. The system reported exhibited the potential to be scalable, which is very relevant from an industrial standpoint. © 2019 Wiley Periodicals, Inc. J. Polym. Sci. 2020, 58, 145–153
Tracheomalacia in bronchopulmonary dysplasia: Trachealis hyper‐relaxant responses to S‐nitrosoglutathione in a hyperoxic murine model

AbstractBackgroundBronchopulmonary dysplasia (BPD) with airway hyperreactivity is a long‐term pulmonary complication of prematurity. The endogenous nonadrenergic, noncholinergic signaling molecule, S‐nitrosoglutathione (GSNO) and its catabolism by GSNO reductase (GSNOR) modulate airway reactivity. Tracheomalacia is a major, underinvestigated complication of BPD. We studied trachealis, left main bronchus (LB), and intrapulmonary bronchiolar (IPB) relaxant responses to GSNO in a murine hyperoxic BPD model.MethodsWild‐type (WT) or GSNOR knockout (KO) newborn mice were raised in 60% (BPD) or 21% (control) oxygen during the first 3 weeks of life. After room air recovery, adult trachealis, LB, and IPB smooth muscle relaxant responses to GSNO (after methacholine preconstriction) were studied using wire myographs. Studies were repeated after GSNOR inhibitor (GSNORi) pretreatment and in KO mice.ResultsGSNO relaxed all airway preparations. GSNO relaxed WT BPD trachealis substantially more than WT controls (P < .05). Pharmacologic or genetic ablation of GSNOR abolished the exaggerated BPD tracheal relaxation to GSNO and also augmented BPD IPB relaxation to GSNO. LB ring contractility was not significantly different between groups or conditions. Additionally, GSNORi treatment induced relaxation of WT IPBs but not trachealis or LB.ConclusionGSNO dramatically relaxed the trachealis in our BPD model, an effect paradoxically reversed by loss of GSNOR. Conversely, GSNOR inhibition augmented IBP relaxation. These data suggest that GSNOR inhibition could benefit both the BPD trachealis and distal airways, restoring relaxant responses to those of room air controls. Because therapeutic options are limited in this high‐risk population, future studies of GSNOR inhibition are needed.
