Writing-to-Learn

description: Despite growing theoretical and empirical evidence that writing has the potential to be an effective tool for student learning in undergraduate mathematics, writing-to-learn integration in mathematics is rare. Major deterrents include perceived lack of alignment between writing and learning goals, deficit views of students’ writing abilities, and the absence of a conceptual framework and methodological tools for systematically examining student learning as evidenced in their writings. To address these issues, this embedded qualitative case study offers a conceptual framework for examining student performance relative to task-specific learning goals in students’ written artifacts. The writings of 10 students enrolled in a Writing-Intensive Precalculus course were analyzed from a module on polynomial functions, resulting in 159 items coded using qualitative content analysis to determine the extent to which students’ writings
description: demonstrated their performance in relation to learning goals. Students were also surveyed and completed a written reflection regarding which writing activities they determined to be most valuable and how they saw writing as contributing to learning. Findings suggest students are overwhelmingly able to produce complete and correct responses to a variety of writing prompts with a moderate level of depth but are less consistent in producing clear responses. Main findings indicate that the structure of the writing assignment, type of question posed, question focus, and individual student inclinations each play a role in the extent to which learning is evidenced in students’ writings. Further, students generally perceive writing as a valuable tool for mathematics learning and for helping them communicate mathematical ideas, reflect on their understanding of course content, think critically, make connections between concepts, deepen their content knowledge, and retain knowledge. Based on these findings, I suggest a number of implications for those seeking to integrate writing into mathematics courses and offer avenues for future research.

Subjects: subject: Engineering, Chemical.

description: The unsteady state heat transfer between gas and solid particles was studied in fluidized beds, 2 and 4 inches in diameter. Air velocities of 0.543 to 4.347 ft./sec. and bed-settled heights to diameter ratios from 0.2 to 8 were employed in transient heating and cooling of 0.004 to 0.2324 inch particles of glass beads, silica gel and alumina between 130 and 288°F. The effect of several variables, particle size (0.004 - 0.2324 inch), bed-settled heights (0.8 - 16 inch) particle densities (8.5 - 206 lbs./cu. ft), thermal conductivities (0.013 - 1.8 Btu/(hr.) (ft.2) (°F/ft.) and air velocities (0.543 - 4.347 ft./sec.) on the space-averaged heat transfer coefficient has been investigated. Using a new approach in interpreting heat transfer driving force, a correlation between the heat transfer coefficient and several parameters for two ranges of modified Reynolds numbers 10 to 60, and 60 to 2200 has been developed (a) for Reynolds number 10 to 60 UDP kf= 0.08CP fmfk f0.4 LsDt -1.3 DPDt 4.3 kskf -4rs rf 7.8DpVf rfmf -6.1; (b) for Reynolds number 60 to 2200 UDpkf =0.0011 CPfmf kf 0.4Ls Dt-1. 3DP Dt4.3 ksk f-4 rsr f7.8 DpVfrf mf -3.1.

description: Background: Climate change is a global threat to health and wellbeing. Here we provide findings of an international research project investigating the health and wellbeing impacts of policies to reduce greenhouse gas emissions in urban environments. Methods: Five European and two Chinese city authorities and partner academic organisations formed the project consortium. The methodology involved modelling the impact of adopted urban climate-change mitigation transport, buildings and energy policy scenarios, usually for the year 2020 and comparing them with business as usual (BAU) scenarios (where policies had not been adopted). Carbon dioxide emissions, health impacting exposures (air pollution, noise and physical activity), health (cardiovascular, respiratory, cancer and leukaemia) and wellbeing (including noise related wellbeing, overall wellbeing, economic wellbeing and inequalities) were modelled. The scenarios were developed from corresponding known levels in 2010 and pre-existing exposure response functions. Additionally there were literature reviews, three longitudinal observational studies and two cross sectional surveys. Results: There are four key findings. Firstly introduction of electric cars may confer some small health benefits but it would be unwise for a city to invest in electric vehicles unless their power generation fuel mix generates fewer emissions than petrol and diesel. Second, adopting policies to reduce private car use may have benefits for carbon dioxide reduction and positive health impacts through reduced noise and increased physical activity. Third, the benefits of carbon dioxide reduction from increasing housing efficiency are likely to be minor and co-benefits for health and wellbeing are dependent on good air exchange. Fourthly, although heating dwellings by in-home biomass burning may reduce carbon dioxide emissions, consequences for health and wellbeing were negative with the technology in use in the cities studied. Conclusions: The climate-change reduction policies reduced CO2 emissions (the most common greenhouse gas) from cities but impact on global emissions of CO2 would be more limited due to some displacement of emissions. The health and wellbeing impacts varied and were often limited reflecting existing relatively high quality of life and environmental standards in most of the participating cities; the greatest potential for future health benefit occurs in less developed or developing countries.

The male writer and the feminine text: Hemingway's major novels from a Cixousian perspective.
Creators: name: Hewson, Marc A.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Literature, American.

description: This dissertation addresses Hemingway's developing understanding of gender and sexual identity in four major novels---The Sun Also Rises, A Farewell to Arms, For Whom the Bell Tolls, and The Garden of Eden---using Cixousian theories about the construction of self-definition. Applying Cixous's ideas of inherent bisexuality and ecriture feminine, the thesis posits Hemingway as a possible member of her elite group of biologically male but psychologically feminine authors to suggest that, as his career advanced, he tried increasingly to define himself in unsettling but crucial ways. Such characters as Brett Ashley and Jake Barnes began the investigation into mediated gender and sexual identity that lasted until the end of his creative life, while Catherine Barkley and Frederic Henry's love established the importance of open and honest sexual relationships as methods of self-discovery. Hemingway's extension of loving relationships by way of the brief but intense affair between Maria and Robert Jordan marked a further movement towards a Cixousian sense of bisexual feminine writing as the lovers focus on life instead of death. Finally, Catherine Bourne's desire to create an anti-patriarchal image of the feminine exposes her creator's own wish to reject restrictive masculine identity in order to try to come to grips with his femininity. Ultimately, of course, Hemingway could not overcome his gender training and admit those of his needs and desires that defied societal standards of masculine behavior. In his writing, however, he indulged in gender-bending and alternative sexuality as a way to express himself creatively. These fictive experiments, often accompanied by real-life counterparts, suggest how much Hemingway wanted to understand men's and women's places in the modern world; and the conclusions to which he came look remarkably like Cixous's. Tracing the similarities between her theories and Hemingway's writing, we might recognize how pervasive Hemingway's questions were and how deeply he wanted to answer them. This attempt to recalibrate the commonly held opinions about Hemingway's life and writing allows us to see more clearly what was at stake for him in the creation of his art by exposing him as a nascent, if unconscious, writer of ecriture feminine.

Mechanisms of neuronal integration in adrenomedullary sympathetic preganglionic neurons.
Creators: name: Wilson, Jennifer M. M.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Biology, Neuroscience.

description: Sympathetic preganglionic neurons innervating the adrenal medulla (AD-SPN) regulate the release of adrenal catecholamines into the bloodstream. This research was undertaken to investigate the intrinsic properties and synaptic pathways characteristic of AD-SPN in neonatal rat spinal cord slice preparation. The presence of Lucifer Yellow from the patch pipette and Rhodamine-Dextran-Lysine from the adrenal medulla in the same neuron post recording identified AD-SPN. Active intrinsic properties revealed and characterised include: a potassium-mediated transient outward rectification present in 96% of AD-SPN and separable into a short 4-aminopyridine- and a long barium-sensitive component; a potassium-mediated sustained outward rectification revealed in TTx, activated positive to -50mV and blocked with quinine. These conductances contribute to the repolarising phase of the action potential. 89% of AD-SPN possessed potassium-mediated anomalous inward rectification. All AD-SPN displayed a high voltage-activated calcium spike that prolongs the action potential. The addition of internal caesium (140mM) revealed a low threshold spike mediated by T-type calcium channels that serve to facilitate burst firing. 75% of AD-SPN exhibited evidence of electrotonic coupling, indicated by characteristic oscillations in membrane potential and confirmed with dual recordings from electrotonically coupled AD-SPN. Electrotonic coupling promoted synchronous activity. An enhanced afterhyperpolarising potential facilitated transient termination of action potential firing forming bursts of activity. A role for calcium in the regulation of neuronal activity via action on electrotonic coupling was suggested by caffeine (10mM) decreasing, BAPTA-AM (15muM) and calcium free aCSF increasing the junctional conductance. Electrical stimulation of the descending fibres in both the ipsi- and contralateral funiculi evoked fast EPSPs in all AD-SPN that were mediated by both NMDA and non-NMDA receptors. A subpopulation of AD-SPN received fast IPSPs mediated by GABA acting via GABAA receptors. A train of stimuli (4 x 10Hz) in ipsi- and contralateral funiculi also evoked a slow IPSP mediated by noradrenaline acting via alpha 2-adrenergic receptors to increase a potassium conductance. The results provide insight into central mechanisms that contribute to the regulation of adrenomedullary catecholamine secretion.

description: Cellulose nanocrystals are a greener alternative to traditional nanomaterials. Thanks to their excellent mechanical properties, they have gained interest as a filler content for polymer composites. In this project, methods were successfully developed to produce cellulose nanocrystals from two Australian native wood sources including an acacia and eucalyptus. The project was then focused on developing chemical strategies to improve the hydrophobicity of produced nanocrystals. The addition of modified cellulose nanocrystals into epoxy polymer network and their enhancement for the mechanical properties of polymer composites were studied in detail.

description: My dissertation is a series of papers that study the effects of school closures in years 2020-21 on parental labor-market outcomes and educational outcomes of secondary and post-secondary students. My first chapter shows that k-12 school and childcare facility closures affect both the mothers and fathers of pre-school and school-age children through a reduction in their work hours, and in some cases earnings. These effects are concentrated among parents without a college degree, parents working in occupations that do not lend themselves to telework, and parents without other family members living at home. My second chapter finds that while high school graduation rates remained stable when schools closed, math proficiency rates suffered, particularly among vulnerable student groups, whereas reading/language and arts proficiency rates saw some improvements. My third chapter shows that university and college closures, coupled with social distancing mandates, led to a decline in both overall and in-state enrollments, with out-of-state enrollments also diminishing in some instances.
An interpretive framework for understanding the politics of policy change.

Subjects: subject: Education, Administration.

description: The research design guiding the study emphasized the development of conceptual elements of policy change, which have been identified in the current policy literature, through the examination of two substantive educational policy changes. A methodology of theoretical sampling was used to develop a conceptual framework grounded in the phenomenology of change. In the first step of the three-stage research path, a number of problematic issues and themes were identified through a review of the literature on policy change. The conceptual trends which emerge from a review of current research on policy processes, identified the core elements of the IF developed in this thesis. Together, the trends identified in the literature suggest that policy change involves a dynamic interplay of ideas, institutional structures and political processes that are embedded in an historical-political context, which emerges from the ecology of interactions within policy communities and policy networks. These elements formed the basis of study's theoretical orientation, and established the direction for the research undertaken to develop the IF. Six research questions developed from the literature provided the framework for the second stage of empirical inquiry into issues surrounding two policy changes made by the government of Ontario, directed at Franco-Ontarian educational governance and funding of Roman Catholic schools. Bill 30, passed in June, 1986, extended full funding for Roman Catholic education to the end of secondary school. Bill 109, enacted in 1988, established a French-language school board in the Ottawa-Carleton region of the province. The politics surrounding these two policy changes were investigated by conducting interviews with 70 policy actors. Documents and newspaper coverage of the policy changes were used to confirm and extend the observations of policy actors. Analysis of the documents and of the taped and transcribed interviews provided the empirical basis for the third and final stage of the study. In this final stage of the research, the conceptual issues identified in the literature were analyzed in the context of the findings of the investigation of the two policy changes. This analysis, reported in two chapters of the thesis, developed the ideas and concepts of the Interpretive Framework (IF) for understanding the politics of policy change.

description: We report new skeletal elements pertaining to the same individual which represents the holotype of Australovenator wintonensis, from the 'Matilda Site' in the Winton Formation (Upper Cretaceous) of western Queensland. The discovery of these new elements means that the hind limb of Australovenator is now the most completely understood hind limb among Neovenatoridae. The new hind limb elements include: the left fibula; left metatarsal IV; left pedal phalanges I-2, II-1, III-4, IV-2, IV-3; and right pedal phalanges, II-2 and III-1. The detailed descriptions are supported with three dimensional figures. These coupled with the completeness of the hind limb will increase the utility of Australovenator in comparisons with less complete neovenatorid genera. These specimens and the previously described hind limb elements of Australovenator are compared with other theropods classified as neovenatorids (including Neovenator, Chilantaisaurus, Fukuiraptor, Orkoraptor and Megaraptor). Hind limb length proportion comparisons indicate that the smaller neovenatorids Australovenator and Fukuiraptor possess more elongate and gracile hind limb elements than the larger Neovenator and Chilantaisaurus. Greater stride lengths to body size exist in both Fukuiraptor and Australovenator with the femur discovered to be proportionally shorter the rest of the hind limb length. Additionally Australovenator is identified as possessing the most elongate metatarsus. The metatarsus morphology varies with body size. The larger neoventorids possess a metatarsus with greater width but shorter length compared to smaller forms.

Overloading a Jackson network of shared queues.
Creators: name: Labrèche, Nadine.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Mathematics.

description: Jackson networks with finite buffers can be designed so that buffer overflows occur with very low probability. Still, queues can be filled beyond capacity so it is of interest to study the distribution of such occurrences and, as a measure of the reliability of the system, the mean time until an overload. The approach we propose is based on a change of measure which twists the stationary Jackson network into a process for which overloads are frequent. For a Jackson network of shared queues with buffer of size $\ell - 1$, we show that the stationary overflow distribution of the twisted network can be used to determine both the limiting distribution (as $\ell\to\infty$) at the moment of overload and the mean time until overload of the original Jackson network. Our estimation for the mean time until an overload is based on an article by Iscoe and McDonald (1994a) in which the mean time until the overflow of a Jackson network is estimated by the reciprocal of the smallest eigenvalue $\Lambda(B)$ of an associated Dirichlet problem. The distinct feature of this estimate is that it comes complete with error bounds so that, unlike estimators, its accuracy can be evaluated. Of course, in practice such eigensystems, however, we obtain an estimate which we show to be asymptotically equivalent to the one proposed by Aldous (1989).
High order image correlation spectroscopy of plasmon-coupled gold nanospheres for their cellular uptake study

Year: 2024

description: High order image correlation spectroscopy is a non-destructive technique which enables one to calculate the gold nanosphere uptake inside a cell. Usually it is difficult to count the gold nanosphere uptake as it has a property called plasmon-coupling. But the high order image correlation spectroscopy helps to overcome this problem. The study can have application in the field of drug delivery where one is concerned about the amount of drug to be delivered to a particular location.
A protein tyrosine kinase associated with the ATP-dependent inactivation of adipose diacylglycerol acyltransferase-1.
Creators: name: Lau, Timothy.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Biology, Animal Physiology.

description: An enzyme activity that reversibly inactivates adipose glycerolphosphate acyltransferase (GPAT) and diacylglycerol acyltransferase (DGAT), in vitro, in the presence of ATP, has been partially purified from adipose tissue with an apparent molecular weight of 68 kDa. The activity responsible for inactivation DGAT is associated with a kinase activity as determined by phosphate incorporation into microsomes and a tyrosine containing peptide. Major substrates of this kinase are two microsomal polypeptides of 53 and 69 kDa. Both DGAT inactivation and kinase activities assayed from the purified sample and the cytosol, have been found to be insensitive to the Ser/Thr kinase inhibitor H-7 while being sensitive to the inhibitors genistein and tyrphostin 25. A crude protein phosphatase preparation from the liver was capable of reversing the effects of both activities. The purified sample was also shown to inactivate GPAT in the presence of ATP. These results suggest that a protein tyrosine kinase, in concert with a protein tyrosine phosphatase, may regulate the activities of DGAT and GPAT by a phosphorylation-dephoshorylation mechanism.

description: Background: Asian medical students and doctors receive lower scores on average than their white counterparts in examinations in the UK and internationally (a phenomenon known as “differential attainment”). This could be due to examiner bias or to social, psychological or cultural influences on learning or performance. We investigated whether students’ scores or feedback show influence of ethnicity-related bias; whether examiners unconsciously bring to mind (activate) stereotypes when judging Asian students’ performance; whether activation depends on the stereotypicality of students’ performances; and whether stereotypes influence examiner memories of performances. Methods: This is a randomised, double-blinded, controlled, Internet-based trial. We created near-identical videos of medical student performances on a simulated Objective Structured Clinical Exam using British Asian and white British actors. Examiners were randomly assigned to watch performances from white and Asian students that were either consistent or inconsistent with a previously described stereotype of Asian students’ performance. We compared the two examiner groups in terms of the following: the scores and feedback they gave white and Asian students; how much the Asian stereotype was activated in their minds (response times to Asian-stereotypical vs neutral words in a lexical decision task); and whether the stereotype influenced memories of student performances (recognition rates for real vs invented stereotype-consistent vs stereotype-inconsistent phrases from one of the videos). Results: Examiners responded to Asian-stereotypical words (716 ms, 95% confidence interval (CI) 702–731 ms) faster than neutral words (769 ms, 95% CI 753–786 ms, p < 0.001), suggesting Asian stereotypes were activated (or at least active) in examiners’ minds. This occurred regardless of whether examiners observed stereotype-consistent or stereotype-inconsistent performances. Despite this stereotype activation, student ethnicity had no influence on examiners’ scores; on the feedback examiners gave; or on examiners’ memories for one performance. Conclusions: Examiner bias does not appear to explain the differential attainment of Asian students in UK medical schools. Efforts to ensure equality should focus on social, psychological and cultural factors that may disadvantage learning or performance in Asian and other minority ethnic students.

description: No statistically significant difference between genders was observed. Among all the comparisons of the 30 second intervals within the 5 minute HRREC data, only two time periods were not statistically significant. One was early in recovery and one was late in recovery. Mean BLa went down every minute from 6.91 mMol at post 1 minute to 6.51 mMol at post 5 minute but this difference was not statistically significant. No statistically significant correlation were found to exist between HRREC and BLaREC. However, PEAKBLa following the test was correlated with HRREC measurements such that the following two trends were found. First, the correlation between PEAKBLa and the absolute HR values obtained at different time intervals during recovery became stronger with increasing time up to the 2nd minute of recovery and second, PEAKBLa was negatively correlated with 5 minute HRREC. PEAKBLa was negatively correlated with the HRREC obtained in the first two minutes of recovery but this relation became positive between the 2nd and 5th minute of recovery.

description: Most multiple sclerosis (MS) patients develop over time a secondary progressive disease course, characterized histologically by axonal loss and atrophy. In early phases of the disease, focal inflammatory demyelination leads to functional impairment, but the mechanism of chronic progression in MS is still under debate. Reactive oxygen species generated by invading and resident central nervous system (CNS) macrophages have been implicated in mediating demyelination and axonal damage, but demyelination and neurodegeneration proceed even in the absence of obvious immune cell infiltration, during clinical recovery in chronic MS. Here, we employ intravital NAD(P)H fluorescence lifetime imaging to detect functional NADPH oxidases (NOX1–4, DUOX1, 2) and, thus, to identify the cellular source of oxidative stress in the CNS of mice affected by experimental autoimmune encephalomyelitis (EAE) in the remission phase of the disease. This directly affects neuronal function in vivo, as monitored by cellular calcium levels using intravital FRET–FLIM, providing a possible mechanism of disease progression in MS.

Drawing on hardboiled detective fiction and noir crime fiction, the novel negotiates the spectrum between these two sub-genres and explores a world that questions modern articulations of Australian masculinity.
Through a practice-led methodology, the exegesis reflexively explores key writerly choices and focuses on genre, masculinity, voice and place.
The project examines how the traditional hardboiled voice and its masculinities are negotiated within a contemporary, post-industrial regional Australian space.

description: Transrectal access still has some unsolved issues such as spatial orientation, infection, access and site closure. This study presents a simple technique to perform transcolonic access with survival in a swine model series. A new technique for NOTES perirectal access to perform retroperitoneoscopy, peritoneoscopy, liver and lymphnode biopsies was performed in 6 pigs, using Totally NOTES technique. The specimens were extracted transanally. The flexible endoscope was inserted through a posterior transmural incision and the retrorectal space. Cultures of bacteria were documented for the retroperitoneal space and intra abdominal cavity after 14 days. Rectal site was closed using non-absorbable sutures. There was no bowel cleansing, nor preoperative fasting. The procedures were performed in 6 pigs through transcolonic natural orifice access using available endoscopic flexible instruments. All animals survived 14 days without complications, and cultures were negative. Histopathologic examination of the rectal closure site showed adequate healing of suture line and no micro abscesses. The results of feasibility and safety of experimental Transcolonic NOTES potentially brings new frontiers and future wider applications for minimally invasive surgery. The treatment of colorectal, abdominal and retroperitoneal diseases through a flexible Perirectal NOTES Access (PNA) is a promising new approach.

description: Cross section data for electron scattering from DNA are important for modelling radiation damage in biological systems. Triply differential cross sections for the electron impact ionization of the highest occupied outer valence orbital of tetrahydrofurfuryl alcohol, which can be considered as an analogue to the deoxyribose backbone molecule in DNA, have been measured using the (e,2e) technique. The measurements have been performed with coplanar asymmetric kinematics at an incident electron energy of 250 eV, an ejected electron energy of 20 eV, and at scattered electron angles of −5°, −10°, and −15°. Experimental results are compared with corresponding theoretical calculations performed using the molecular 3-body distorted wave model. Some important differences are observed between the experiment and calculations.

description: Background Globally, Médecins Sans Frontières (MSF) treats more than 300,000 severely malnourished children annually. Malnutrition is not only caused by lack of food and poor infant and child feeding practices but also by illnesses. Breaking the vicious cycle of illness and malnutrition by providing ill children with nutritional supplementation is a potentially powerful strategy for preventing malnutrition that has not been adequately investigated. Therefore, MSF investigated whether incidence of malnutrition among ill children <5 y old could be reduced by providing a fortified food product or micronutrients during their 2-wk convalescence period. Two trials, one in Nigeria and one in Uganda, were conducted; here we report on the trial that took place in Goronyo, a rural region of northwest Nigeria with high morbidity and malnutrition rates. Methods and Findings We investigated the effect of supplementation with ready-to-use therapeutic food (RUTF) and a micronutrient powder (MNP) on the incidence of malnutrition in ill children presenting at an outpatient clinic in Goronyo during February to September 2012. A three-armed, partially-blinded, randomised controlled trial was conducted in children diagnosed as having malaria, diarrhoea, or lower respiratory tract infection. Children aged 6 to 59 mo were randomised to one of three arms: one sachet/d of RUTF; two sachets/d of micronutrients or no supplement (control) for 14 d for each illness over 6 mo. The primary outcome was the incidence of first negative nutritional outcome (NNO) during the 6 mo follow-up. NNO was a study-specific measure used to indicate occurrence of malnutrition; it was defined as low weight-for-height z-score (

description: Objectives: To determine the association between Toxoplasma gondii infection and Parkinson's disease and to investigate whether T. gondii seropositivity is associated with the general characteristics of patients with Parkinson's disease. Design Case–control study. Setting: Cases and controls were enrolled in Durango City, Mexico. Participants: 65 patients with Parkinson's disease and 195 age- and gender-matched control subjects without Parkinson's disease. Primary and secondary: outcome measures Serum samples of participants were analysed for anti-T. gondii IgG and IgM antibodies by commercially available enzyme-linked immunoassays. Prevalence of T. gondii DNA was determined in seropositive subjects using PCR. The association between clinical data and infection was examined by bivariate analysis. Results: Anti-T. gondii IgG antibodies were found in 6/65 cases (9.2%) and in 21/195 controls (10.8%) (OR 0.84; 95% CI 0.32 to 2.18; p=0.81). The frequency of high (>150 IU/mL) antibody levels was similar among cases and controls (p=0.34). None of the anti-T. gondii IgG positive cases and four of the anti-T. gondii IgG positive controls had anti-T. gondii IgM antibodies (p=0.54). The prevalence of T. gondii DNA was comparable in seropositive cases and controls (16.7% and 25%, respectively; p=1.0). Seroprevalence of T. gondii infection was associated with a young age onset of disease (p=0.03), high Unified Parkinson Disease Rating Scale scores (p=0.04) and depression (p=0.02). Seropositivity to T. gondii infection was lower in patients treated with pramipexole than in patients without this treatment (p=0.01). However, none of the associations remained significant after Bonferroni correction. Conclusions: The results do not support an association between T. gondii infection and Parkinson's disease. However, T. gondii infection might have an influence on certain symptoms of Parkinson's disease. Further research to elucidate the role of T. gondii exposure on Parkinson's disease is warranted.

description: In order to determine the relevance of microplastic particles in various environmental media, comprehensive investigations are needed. However, no analytical method exists for fast identification and quantification. At present, optical spectroscopy methods like IR and RAMAN imaging are used. Due to their time consuming procedures and uncertain extrapolation, reliable monitoring is difficult. For analyzing polymers Py-GC-MS is a standard method. However, due to a limited sample amount of about 0.5 mg it is not suited for analysis of complex sample mixtures like environmental samples. Therefore, we developed a new thermoanalytical method as a first step for identifying microplastics in environmental samples. A sample amount of about 20 mg, which assures the homogeneity of the sample, is subjected to complete thermal decomposition. The specific degradation products of the respective polymer are adsorbed on a solid-phase adsorber and subsequently analyzed by thermal desorption gas chromatography mass spectrometry. For certain identification, the specific degradation products for the respective polymer were selected first. Afterwards real environmental samples from the aquatic (three different rivers) and the terrestrial (bio gas plant) systems were screened for microplastics. Mainly polypropylene (PP), polyethylene (PE) and polystyrene (PS) were identified for the samples from the bio gas plant and PE and PS from the rivers. However, this was only the first step and quantification measurements will follow. © 2017 Elsevier Ltd.
