Negative Correlations Between Cultivable Pyrene-degrading Sphingomonas and Active Soil Pyrene Degraders Explain Bioaugmentation Postpone or Failure

Background: Bioaugmentation is an effective approach to remediate soils contaminated by polycyclic aromatic hydrocarbon (PAHs), but suffers from unsatisfactory performance in engineering practices. It is hypothetically explained by the complicated interactions between indigenous microbes and introduced degrading consortium. This study isolated a cultivable pyrene degrader (Sphingomonas sp. YT1005) and an active pyrene degrading consortium consisting of Gp16, Streptomyces, Pseudonocardia, Panacagrimonas, Methylotenera and Nitrospira by magnetic-nanoparticle mediated isolation (MMI) from soils.Results: Pyrene biodegradation was postponed in bioaugmentation with Sphingomonas sp. YT1005, explained by its negative correlations with the active pyrene degraders. In contrast, amendment with the active pyrene degrading consortium, pyrene degradation efficiency increased by 30.17%. In addition, pyrene degradation efficiency was positively correlated with the abundance of pyrene dioxygenase encoding genes (nidA, nidA3 and PAH-RHDα-GP), which significantly increased in MMI-isolated consortium. Pyrene degradation by Sphingomonas sp. YT1005 only followed the phthalate pathway, whereas the MMI-isolated pyrene degrading consortium exhibited both phthalate and salicylate pathways. The results indicated that Sphingomonas sp. YT1005 was not the actual pyrene degrader in soils, and MMI could successfully isolate the active pyrene degraders that were suitable for bioaugmentation.Conclusion: This work revealed the microbial intra-correlations during the bioaugmentation process, uncovered the underlying mechanisms of bioaugmentation postpone with cultivable degraders, and provided a deeper insight into the actual pyrene degraders and degradation pathways in PAHs contaminated soils. Our findings gave new explanations for bioaugmentation postpone or failure, and offered clues to enhance bioaugmentation performance by the active degraders using MMI.
Normal Tension Primary Ppen-Angle Glaucoma with Progressive Synechial Angle Closure in Senior Chinese

Background: This study is to address a unique subtype of combined-mechanism glaucoma (CMG), normal tension glaucoma (NTG) with progressive synechial angle closure in the Chinese senior population, whose clinical course and treatment targets are quite different from classic primary angle-closure glaucoma (PACG). Methods: In this retrospective study, 12 patients with NTG plus primary angle closure suspect or primary angle closure were included in the CMG group, and 12 classic PACG patients with matched extent of glaucomatous optic neuropathy (GON) were included in the control (PACG) group. Clinical features and detailed histories of disease development were investigated and compared between these two groups.Results: There were 6 females and 6 males in CMG group, 3 males and 9 females in PACG group. No statistical significances were found in age (63.42 ± 5.90 vs. 59.42 ± 7.47 years), preoperative intraocular pressure (20.75 ± 5.06 vs. 21.25 ± 4.47 mmHg), anterior chamber depth (ACD) (1.98 ± 0.28 vs. 1.94 ± 0.21mm), mean deviation of visual field (24.37 ± 6.54 vs. 22.01 ± 0.85 dB), average retinal nerve fiber layer thickness (48.00 ± 14.00 vs. 57.25 ± 14.10 μm), cup-to-disc (C/D) ratio (0.89 ± 0.07 vs. 0.87 ± 0.07) and axial length (22.69 ± 0.76 vs. 22.47 ± 0.69 mm) between the two groups (P > 0.05). The extent of synechial angle closure in PACG group was more extensive than that in CMG group, as evaluated by the number of “clock hours” (3.96 ± 1.14 vs. 9.38 ± 1.99, P < 0.05), although the severity of GON was comparable.Conclusion: If NTG develops with synechial angle closure, it might be misdiagnosed as PACG. We need to recognize and scrutinize this specific subtype of CMG, which is very common in the Chinese senior population, but widely neglected. In contrast to classic PACG, treatment targets in NTG with progressive synechial angle closure is primarily in consistent with those in NTG.

Assessing Problematic Facebook Use: Psychometric Properties of the Polish Version of Facebook Intrusion Questionnaire

BackgroundFacebook is used for work, entertainment and communication. However, there is potential for problematic or addictive use which can cause significant mental and physical health problems. The Facebook Intrusion Questionnaire (FIQ; Elphinston & Noller, 2011) is one of the most widely used measures of problematic Facebook use. However, no previous study has validated this measure in a Polish population. MethodsThe study aims to validate the Polish adaptation of FIQ. Five large samples of Polish Facebook users (N = 12,753; M age = 21 years; 66% female) were used to examine the psychometric properties of the Polish version of the FIQ. ResultsAn exploratory and confirmatory factor analysis provided support for a unidimensional factor structure (χ2(16) = 199.53, p< 0.001; RMSEA = 0.042; SRMR = 0.022; CFI = 0.950). Item response theory showed that the adapted FIQ items had adequate discrimination and information levels. ConclusionThe Polish version of the FIQ showed good internal consistency and adequate construct validity. Overall, the findings suggest that the FIQ is a reliable and valid measure for use in the Polish population.

Recreational Horseback Riding and Its Association with Physical, Mental, and Social Wellbeing and Perceived Health

ABSTRACT Physical activity and its influence on wellbeing are evident. It is an open question if the recommended activity levels can be reached by middle-aged and older (45+ years) horseback riders. Therefore the aim of the study was to assess physical activity (horseback riding) in horseback riders in comparison with dog owners (dog walking) and people without pets (non-animal-related activities) and its relation to physical, mental, and social wellbeing. The FAHW12- (self-assessment for habitual wellbeing of Wydra) and a self-designed questionnaire were used to determine overall wellbeing and its component dimensions. The study was carried out in Austria. Overall 178 people aged 45+ years answered a questionnaire about physical activity and wellbeing within the physical, mental, and social wellbeing domains. Comparisons were made using a general linear model, with activity group (riders, dog owners, controls) as the main variable of interest. Physical activity levels were not significantly different between riders (107.4±62.0 metabolic equivalent-hours per week; MET-h/week) and dog owners (137.4±116.7 MET-h/week), but were significantly higher compared with controls (without pets) (21.6±19.9 MET-h/week). Overall wellbeing scores of riders were not significantly higher compared with dog owners (15.5±0.8 vs. 13.3±0.9; p = 0.071), but statistically significantly higher compared with controls (11.6±0.9; p = 0.002). The physical wellbeing of riders was significantly higher (1.5 times, p = 0.024) compared with dog owners, and 1.7 times higher compared with controls (p = 0.006). Mental wellbeing scores of riders were significantly higher compared with controls but not compared with dog owners. Horseback riding is a means to reach recommended physical activity levels. This activity is associated with greater physical and mental wellbeing, when compared with non-pet owning people, and is similar to that seen in dog owners.

Osteoclast behaviour on synthetic bioglasses with different crystallinity in vitro

The effect of crystallization on biodegradation of synthetic bioglasses was studied with a particular attention to the osteoclast behaviour. Bioglasses SG600, SG900 and SG1100 were synthesized by the sol-gel method. Further treatments with increasing temperatures influenced and determined the crystallization degree of the material. Primary cultured rat osteoclasts were incubated for four hours and 48 hours on samples. Osteoclast actin labelling was examined by cytochemical staining. The concentrations of Ca and P in culture medium were quantified by colorimetric methods. SEM examined osteoclast morphology and resorption lacuna. Actin staining reveals on all three materials the typical adhesion contact ring. The Ca concentration in the culture medium of ARBEITEN ORIGINAL H.F.

Data-Driven Beam Management With Angular Domain Information for mmWave UAV Networks

Unmanned aerial vehicles (UAVs) have extensive civilian and military applications, but establishing a UAV network providing high data rate communications with low delay is a challenge. Millimeter wave (mmWave), with its high bandwidth nature, can be adopted in the UAV network to achieve high speed data transfer. However, it is difficult to establish and maintain the mmWave communication links due to the mobility of UAVs. In this paper, a beam management scheme utilizing angular domain information (ADI) is proposed to rapidly establish and reliably maintain the communication links for the mmWave UAV network. Firstly, Gaussian process machine learning (GPML)-enabled position prediction is proposed to facilitate coarse-ADI acquisition through the proposed UAV clustering algorithm. Then, with the proposed confined-ADI acquisition which removes the redundancy in the coarse-ADI acquisition, fast beam tracking with respectively the single-beam pattern and the multi-beam pattern is achieved. Finally, a data-driven beam pattern selection scheme is proposed for improving the spectrum efficiency. Simulation results verify the outstanding performance of the proposed beam management for mmWave UAV networks.
Voltage-Gain Design and Efficiency Optimization of Series/Series-Parallel Inductive Power Transfer System Considering Misalignment Issue

Compensation is key to an inductive power transfer (IPT) system in terms of voltage transfer function and efficiency optimization. Basic compensation is simple, but not suitable, for the achievement of variable load-independent voltage-gains without changing the design of the loosely-coupled transformer (LCT). On the other hand, higher-order compensation circuits enable greater design freedom to achieve variable load-independent voltage-gains while keeping the LCT unchanged, but it requires a variety of compensation components, especially the inductive components, which incur significant copper and core losses. This paper proposes a comprehensive design of the series/series-parallel (S/SP) IPT system. The design methodology for variable load-independent voltage-gains is studied to keep the LCT unchanged and achieve zero phase angle input over the whole load range. Design consideration includes the effect of misalignment issue on the voltage-gain and, thus, a design criteria can be derived to ensure an acceptable sensitivity to the misalignment when taking efficiency optimization. The experimental results are presented for verification.
Iron Oxide (Fe3O4)-Supported SiO2 Magnetic Nanocomposites for Efficient Adsorption of Fluoride from Drinking Water: Synthesis, Characterization, and Adsorption Isotherm Analysis

This research work reports the magnetic adsorption of fluoride from drinking water through silica-coated Fe3O4 nanoparticles. Chemical precipitation and wet impregnation methods were employed to synthesize the magnetic nanomaterials. Moreover, the synthesized nanomaterials were characterized for physicochemical properties through scanning electron microscopy, Fourier-transform infrared spectroscopy, and X-ray powder diffraction. Screening studies were conducted to select the best iron oxide loading (0.0–1.5 wt%) and calcination temperature (300–500 °C). The best selected nanomaterial (0.5Fe-Si-500) showed a homogenous FeO distribution with a 23.79 nm crystallite size. Moreover, the optimized reaction parameters were: 10 min of contact time, 0.03 g L−1 adsorbent dose, and 10 mg L−1 fluoride (F−) concentration. Adsorption data were fitted to the Langmuir and Freundlich isotherm models. The Qm and KF (the maximum adsorption capacities) values were 5.5991 mg g−1 and 1.869 L g−1 respectively. Furthermore, accelerated adsorption with shorter contact times and high adsorption capacity at working pH was among the outcomes of this research work.
Habitat Patch Size and Landscape Structure Influence, Although Weakly, the Parasite Richness of an Arboreal Folivorous-frugivorous Primate in Anthropogenic Landscapes

ContextAnthropogenic habitat disturbances that affect the ecology and behavior of parasites and hosts can either facilitate or compromise their interactions and modulate the parasite richness.ObjectivesWe assessed if the size of the habitat patch, the composition and configuration of the landscape (forest cover, patch density and mean distance to the nearest patch) and host group size influence the parasite richness of brown howler monkeys (Alouatta guariba clamitans) inhabiting forest fragments immersed in an anthropogenic matrix.MethodsWe collected fecal samples from 60 howler monkey groups inhabiting distinct forest fragments (one group/fragment) from January to July 2019. We used generalized linear models to assess the power of the independent variables in predicting parasite richness at the patch- and patch-landscape scales.ResultsWe found 10 parasite taxa (five basal eukaryotes, four nematodes and one platyhelminth), nine of which also infect humans or domestic animals. Overall parasite richness showed an inverse relationship with habitat patch size and forest cover, and a direct relationship with the mean distance to the nearest patch and group size. Patch-landscape metrics and host group size also influenced the infection with parasites with direct cycle and transmission via ingestion of the infective stage in the arboreal environment or with parasites with indirect cycle and transmission via ingestion of intermediate hosts. However, all significant models presented low weight.ConclusionsWe suggest that characteristics of parasite and host populations among other factors are more critical modulators of the relationship between howler monkeys and their parasites in anthropogenic landscapes.
Evolution of prudent predation in complex food webs

Abstract Prudent predators catch sufficient prey to sustain their populations but not as much as to undermine their populations’ survival. The idea that predators evolve to be prudent has been dismissed in the 1970s, but the arguments invoked then are untenable in the light of modern evolution theory. The evolution of prudent predation has repeatedly been demonstrated in two‐species predator–prey metacommunity models. However, the vigorous population fluctuations that these models predict are not widely observed. Here we show that in complex model food webs prudent predation evolves as a result of consumer‐mediated (‘apparent’) competitive exclusion of resources, which disadvantages aggressive consumers and does not generate such fluctuations. We make testable predictions for empirical signatures of this mechanism and its outcomes. Then we discuss how these predictions are borne out across freshwater, marine and terrestrial ecosystems. Demonstrating explanatory power of evolved prudent predation well beyond the question of predator–prey coexistence, the predicted signatures explain unexpected declines of invasive alien species, the shape of stock–recruitment relations of fish, and the clearance rates of pelagic consumers across the latitudinal gradient and 15 orders of magnitude in body mass. Specific research to further test this theory is proposed.
A Community Based Study on the Consequence of Polypharmacy in the Quality of Life among Geriatric Population

Polypharmacy is defined by the World health organization as “the administration of the many drugs at an equivalent time or the administration of an excessive number of drugs”. Polypharmacy is frequent among elderly as they often suffer from chronic diseases with concomitant pathologies. Polypharmacy is related to adverse outcomes including mortality, falls, adverse drug reactions, increased length of stay in hospital and readmission to hospital soon after discharge. The risk of adverse effects and harm increases with increasing numbers of medications. It is associated with decreased quality of life, self-rated health, mobility and functional ability as well as increases in hospitalizations, physiological distress, use of health care resources, mortality and costs. The study was prospective and observational and was conducted between the geriatric population in Mangalore. A total of 150 subjects were included in this study and the case reports were analyzed. Patient demographic details, patient drug chart and the medication-related quality of life (MRQoL) of the patients were analyzed. The subjects were selected according to the selection criteria and included individuals aged 60 years and above under a drug therapy with five or more drugs in numbers. Out of the identified subjects, 79 were male (52.7%) and 71 were female (47.3%). Out of this 150 subjects with polypharmacy, 44 individuals (22.7%) had major drug interactions. Patient safety is the most important aspect of health care system since the medicine can cure illness and at the same time harm the patient if not appropriately used. Clinical pharmacist can play a key role in promoting better medication use, ensuring that patients receive appropriate pharmacotherapy thus helps in minimizing the risk of unfavorable outcomes of pharmacotherapy.
