Human Activities Inducing High CH4 Diffusive Fluxes in an Agricultural River Catchment in Subtropical China

Methane (CH4) is one of the key greenhouse gases (GHGs) in the atmosphere with current concentration of 1859 ppb in 2017 due to climate change and anthropogenic activities. Rivers are of increasing concern due to sources of atmospheric CH4. However, knowledge and data limitations exist for field studies of subtropical agricultural river catchments, particularly in southern China. The headspace balance method and the diffusion model method were employed to assess spatiotemporal variations of CH4 diffusive fluxes from April 2015 to January 2016 in four order reaches (S1, S2, S3, and S4) of the Tuojia River, Hunan, China. Results indicated that both the dissolved concentrations and diffusive fluxes of CH4 showed obvious spatiotemporal variations. The observed mean concentration and diffusive flux of CH4 were 0.40 ± 0.02 μmol L−1 and 41.19 ± 2.50 µg m−2 h−1, respectively, showing the river to be a strong source of atmospheric CH4. The CH4 diffusive fluxes during the rice-growing seasons were significantly greater than the winter fallow season (an increase of 80.26%). The spatial distribution of CH4 diffusive fluxes increased gradually from (17.58 ± 1.42) to (55.56 ± 4.32) µg m−2 h−1 due to the organic and nutrient loading into the river waterbodies, with the maximum value at location S2 and the minimum value at location S1. Correlation analysis showed that the CH4 diffusive fluxes exhibited a positive relationship with the dissolved organic carbon (DOC), salinity, and water temperature (WT), while a negative correlation occurred between CH4 diffusive fluxes and the dissolved oxygen (DO) concentration, as well as the pH value. Our findings highlighted that a good understanding of exogenous nutrient loading in agricultural catchments will clarify the influence of human activities on river water quality and then constrain the global CH4 budget.
An ethnographic study on leadership-as-practice in trauma simulation training

Purpose This study aims to discover how leadership emerges in a hospital’s trauma team in a simulated trauma care situation. Instead of investigating leadership from a leader-centric perspective, or using a metrics-based approach to reach generalizable results, the study aims to draw from post-heroic theories by applying leadership-as-practice and sociomaterial perspectives that emphasize the cultural-historical context and emergent nature of leadership. Design/methodology/approach The study was conducted in a Finnish central hospital through ethnographic observations of 14 in situ trauma simulation trainings over a period of 13 months. The data consist of vignettes developed and written from field notes. The analysis was informed by the cultural-historical activity theory. Findings Leadership in a trauma team during an in situ simulation training emerges from a complex system of agencies taking place simultaneously. Contextual elements contributed to the goal. Clarity of roles and task division, strong execution of leadership at critical points, active communication and maintenance of disciplined communication helped to overcome difficulties. The team developed coordination of the process in conjunction with the care. Originality/value The study considers trauma leadership to be a practical phenomenon emerging from the trauma team’s sociomaterial context. The results can be used to develop non-technical skills training within the field of simulation-based medical training.
Resistance of bonded premolars to four artificial ageing models post enamel conditioning with a novel calcium-phosphate paste

Background This in vitro study compares a novel calcium-phosphate etchant paste to conventional 37% phosphoric acid gel for bonding metal and ceramic brackets by evaluating the shear bond strength, remnant adhesive and enamel damage following water storage, acid challenge and fatigue loading. Material and Methods Metal and ceramic brackets were bonded to 240 extracted human premolars using two enamel conditioning protocols: conventional 37% phosphoric acid (PA) gel (control), and an acidic calcium-phosphate (CaP) paste. The CaP paste was prepared from β-tricalcium phosphate and monocalcium phosphate monohydrate powders mixed with 37% phosphoric acid solution, and the resulting phase was confirmed using FTIR. The bonded premolars were exposed to four artificial ageing models to examine the shear bond strength (SBS), adhesive remnant index (ARI score), with stereomicroscopic evaluation of enamel damage. Results Metal and ceramic control subgroups yielded significantly higher (p < 0.05) SBS (17.1-31.8 MPa) than the CaP subgroups (11.4-23.8 MPa) post all artificial ageing protocols, coupled with higher ARI scores and evidence of enamel damage. In contrast, the CaP subgroups survived all artificial ageing tests by maintaining adequate SBS for clinical performance, with the advantages of leaving unblemished enamel surface and bracket failures at the enamel-adhesive interface. Conclusions Enamel conditioning with acidic CaP pastes attained adequate bond strengths with no or minimal adhesive residue and enamel damage, suggesting a suitable alternative to the conventional PA gel for orthodontic bonding. Key words:Enamel etching, calcium phosphate, bracket bond strength, adhesive residue, enamel damage.

THE KINETICS OF TWO HETEROTROPHIC TETRACHLOROETHENE-RESPIRING POPULATIONS AND THEIR EFFECTS ON THE SUBSTRATE INTERACTIONS WITH DEHALOCOCCOIDES STRAINS

Title of Document: THE KINETICS OF TWO HETEROTROPHIC TETRACHLOROETHENE-RESPIRING POPULATIONS AND THEIR EFFECTS ON THE SUBSTRATE INTERACTIONS WITH DEHALOCOCCOIDES STRAINS Deyang Huang, Doctor of Philosophy, 2009 Directed By: Associate Professor, Jennifer G. Becker, Department of Environmental Science and Technology This study focused on evaluating how interactions between the hydrogenotroph Dehalococcoides ethenogenes strain 195, which is able to completely dechlorinate tetrachloroethene (PCE) to ethene, and the two heterotrophs Desulfuromonas michiganensis strain BB1 and Desulfitobacterium sp. strain PCE1, which dechlorinate PCE to either cis-dichloroethene (cis-DCE) or trichloroethene (TCE), on the fate of PCE under common in situ bioremediation scenarios. Meaningful kinetic parameter estimates were obtained for the heterotrophic dehalorespirers under a wide range of conditions. Batch culture assays and numerical experiments were conducted with Desulfuromonas michiganensis to evaluate the effect of the initial conditions including the ratio of the initial substrate concentration (S0) to the initial biomass concentration (X0) and the ratio of S0 to the half-saturation constant (KS) on parameter correlation. Most importantly, S0/KS, but not S0/X0, strongly influenced parameter correlation. Correlation between the Monod kinetic parameters could be minimized by maximizing S0/KS. In the present study, dechlorination of high PCE concentrations by Desulfuromonas michiganensis and Desulfitobacterium sp. strain PCE1 was monitored. The maximum level of PCE that could be dechlorinated by each strain was not constant, and varied with X0. This phenomenon could not be described using conventional Monod kinetics; therefore, a new model that incorporated an inactivation term into the biomass growth equation was developed to describe dechlorination at high PCE concentrations. The interactions among Dehalococcoides ethenogenes and heterotrophic dehalorespirer in continuous-flow stirred tank reactors (CSTRs) were performed under two conditions that reflect either a natural attenuation or engineered bioremediation treatment scenario. Extant kinetic estimates accurately predicted the steady-state chlorinated ethene concentrations in the CSTRs. However, intrinsic kinetic parameter estimates better described the CSTR start-up phase. The modeling and experimental results suggested that the ability of Dehalococcoides ethenogenes to utilize PCE and TCE is limited by the presence of a PCE-to-TCE/cis-DCE dehalorespirer, which forces Dehalococcoides ethenogenes to function primarily as a cis-DCE-respiring population. This study provides insight into how the activities of different dehalorespiring cultures are interrelated and will aid in the design of engineered bioremediation approaches that optimize the potential benefits associated with different dehalorespiring populations to achieve efficient and effective clean-up of PCEand TCE-contaminated sites.
Decoding the vital segments in human ATP-dependent RNA helicase

An analysis of the ATP-dependent RNA helicase using known functionally close analogs helps disclose the structural and functional information of the enzyme. The enzyme plays several interlinked biological functions and there is an urgent need to interpret its key active-site residues to infer function and establish role. The human protein q96c10.1 is annotated using tools such as interpro, go and cdd. The physicochemical properties are estimated using the tool protparam. We describe the enzyme protein model developed using modeller to identify active site residues. We used consurf to estimate the structural conservation and is evolutionary relationship is inferred using known close sequence homologs. The active site is predicted using castp and its topological flexibility is estimated through cabs-flex. The protein is annotated as a hydrolase using available data and ddx58 is found as its top-ranked interacting protein partner. We show that about 124 residues are found to be highly conserved among 259 homologs, clustered in 7 clades with the active-site showing low sequence conservation. It is further shown that only 9 loci among the 42 active-site residues are conserved with limited structural fluctuation from the wild type structure. Thus, we document various useful information linked to function, sequence similarity and phylogeny of the enzyme for annotation as potential helicase as designated by uniprot. Data shows limited degree of conserved sequence segments with topological flexibility unlike in other subfamily members of the protein.
An Overview of Morphological and Molecular Screening of Antifungal Genes against Northern Corn Leaf Blight (Exserohilum turcicum) from Maize Genotypes-A Review

The global food demand is increasing at a rapid rate and the world population is expected reach 9 billion by 2050 and 50 per cent of the arable land is predicted to be deteriorated due to drought and salinity by 2050 (Fig 1). Thus, in order meet the food requirement the production must be increased by at least 35 per cent annually (Shelden and Roessner, 2013). Maize (Zea mays L.) one of the third most important food crop in the world having greater global importance for food, fodder, and fuel. The global food demand and food production is constantly unbalanced.

Chemosensory Event-related Potentials in 3M Syndrome Infants: An Early Biomarker Based on EEG Signal Processing

3M syndrome is a rare disorder that involves the gene CUL7. CUL7 modulates odour detection, conditions the olfactory response (OR) and plays a role in olfactory system development. Despite this involvement, there are no direct studies on olfactory functional effects in 3M syndrome. The purpose of the present work was to analyse the cortical OR, through chemosensory event-related potentials (CSERP) and power spectra calculated by electroencephalogram (EEG) signals recorded in 3M infants: two twins (3M-N) and an additional subject (3M-O). The results suggest that olfactory processing is diversified. Comparison of N1 and LPC components indicated substantial differences in 3M syndrome that may be a consequence of a modified olfactory processing pattern. Moreover, the presence of delta rhythms in 3M-O and 3M-N clearly indicates their involvement with OR, since the delta rhythm is closely connected to chemosensory perception, in particular to olfactory perception.

Evaluation de l'efficacité de traitements enzymatiques sur les biofilms et étude du risque lié au détachement des bactéries : cas de Pseudomonas aeruginosa

Les biofilms bacteriens peuvent etre source de dissemination de flores pathogenes apres application d'un traitement antimicrobien inefficace ou suite au detachement naturel de bacteries. La premiere partie de cette these etudie l'efficacite de cocktails enzymatiques pour l'elimination de biofilms bacteriens en conditions de laboratoire. Une importante variabilite est demontree en fonction de la nature du biofilm, de la nature du cocktail enzymatique et des parametres d'application du traitement. La seconde partie des travaux tente d’evaluer le risque associe au detachement naturel de bacteries depuis les biofilms. Plus particulierement, le cas de P. Aeruginosa est etudie. A partir d’un dispositif d’etude original developpe au laboratoire, la caracterisation physiologique et l’evaluation du potentiel de virulence des cellules detachees de biofilms sont entreprises. Le travail est mene de maniere comparative sur des cellules detachees, des cellules sessiles, et des cellules planctoniques. Les resultats mettent en evidence l’expression d’un phenotype global transitoire entre l’etat sessile et l’etat planctonique apres detachement naturel des cellules de biofilms. En particulier, les cellules detachees montrent une meilleure capacite a former de nouveaux biofilms que les cellules planctoniques. Dans l’etude de la production in vitro de facteurs de virulence, elles montrent egalement un potentiel de virulence intermediaire entre ceux des cellules sessiles et planctoniques. L’ensemble de ces resultats suggere donc qu’une mauvaise elimination des biofilms peut representer un risque eleve lie a la recolonisation des surfaces par les bacteries detachees et a leur virulence.
Serum 25(OH) Vitamin D Levels of Adolescent and Young Medical Students

Objectives: The purpose of this study was to determine vitamin D levels in adolescents and young medical students and to name factors that affect vitamin D levels. Materials and methods: This prospective clinical study was conducted with healthy medical students aged up to 24 years. Height, weight and waist circumference were measured; body mass index (BMI) was calculated and each participant was questioned on demographic characteristics. Blood samples for Ca, P, ALP, PTH and 25(OH)D vitamin levels were drawn after an 8-hour fast. For vitamin D levels, ≥ 30 ng/mL was considered sufficient, 21-29 mg/dL insufficient and ≤ 20 ng/mL as vitamin D deficiency. Results: Of patients in the study, 47.6% (n = 276) were female and 52.4% (n = 304) were male; the mean age was 19.2 ± 1.00 years. Only 8.8% of students (n = 51) had sufficient vitamin D levels. Some 91.2% of students had low vitamin D levels; 54.1% deficiency, 37.1% insufficiency and 14% severe vitamin D deficiency. Sex, BMI, traditional clothing, spending less time in sunny areas and physical activity status had a statistically significant relation with 25(OH)D levels. Conclusion: Vitamin D deficiency is common in adolescents and young people. Female adolescents are especially at risk for vitamin D deficiency. Being female, traditional clothing style, being underweight, sun avoidance, lack of physical activity, smoking and alcohol use are risk factors for vitamin D deficiency. Vitamin D levels should be screened in high-risk groups and low vitamin D levels must be treated.
Contact with Mental Health Services After Acute Care for Self-Harm Among Adults Released from Prison: A Prospective Data Linkage Study.

OBJECTIVE To determine the care pathway and rate and predictors of mental health care contact within seven days of discharge from acute care following self-harm. METHOD In a representative cohort of adults released from prisons in Queensland, Australia, we probabilistically linked person-level, statewide ambulance, emergency department, and hospital records, both prospectively and retrospectively, and community mental health service and Medicare records prospectively, to baseline survey data. We fit multivariate modified log-linked Poisson regression models to examine the association between sociodemographic, health, and criminal justice factors and mental health care contact after self-harm. RESULTS Of 217 discharges from acute care following self-harm, 55% (n = 119) received mental health care within seven days of discharge. Mental health care contact was associated with substance use disorder (adjusted relative risk (ARR) = 0.48; 95% CI: 0.27-0.85), dual diagnosis (ARR = 0.58; 95% CI: 0.41-0.82), physical health-related functioning (ARR = 0.98; 95% CI: 0.97-0.99), being female (ARR = 1.39; 95% CI: 1.02-1.90), being identified as at risk of self-harm by correctional authorities (ARR = 1.50; 95% CI: 1.07-2.09), and prior engagement with state-funded mental health care (ARR = 1.55; 95% CI: 1.08-2.22). CONCLUSION Our findings highlight the need to improve the integration of community mental health care for people who present to acute care following self-harm with a recent history of incarceration, particularly for men and those with substance use disorder or dual diagnosis.
