description: Abstract Background A healthcare provider's recommendation to undergo screening has been shown to be one of the strongest predictors of completing a colorectal cancer (CRC) screening test. We sought to determine the relationship between the general quality of self-rated patient-provider communication and the completion of CRC screening. Methods A formative study using qualitative data from focus groups and quantitative data from a cross-sectional survey of church members about the quality of their communication with their healthcare provider, their CRC risk knowledge, and whether they had completed CRC screening tests. Focus group participants were a convenience sample of African American church members. Participants for the survey were recruited by telephone from membership lists of 12 African American churches located in rural counties of North Carolina to participate in the WATCH (Wellness for African Americans Through Churches) Project. Results Focus Groups. Six focus groups (n = 45) were conducted prior to the baseline survey. Discussions focused on CRC knowledge, and perceived barriers/motivators to CRC screening. A theme that emerged during each groups' discussion about CRC screening was the quality of the participants' communication with their health care provider. Survey. Among the 397 participants over age 50, 31% reported CRC screening within the recommended guidelines. Participants who self-rated their communication as good were more likely to have been screened (36%) within the recommended guidelines than were participants with poor communication (17%) (OR = 2.8, 95% CI 1.2, 6.4; p = 0.013). Participants who had adequate CRC knowledge completed CRC screening at a higher rate than those with inadequate knowledge (p = 0.011). The percentage of participants with CRC screening in the recommended guidelines, stratified by communication and knowledge group were: 42% for good communication/adequate knowledge; 27% for good communication/inadequate knowledge; 29% for poor communication/adequate knowledge; and 5% for poor communication/inadequate knowledge. Conclusions Participants who rated their patient-provider communication as good were more likely to have completed CRC screening tests than those reporting poor communication. Among participants reporting good communication, knowledge about colorectal cancer was also associated with test completion. Interventions to improve patient-provider communication may be important to increase low rates of CRC screening test completion among African Americans.

Literal and figurative meanings of Spanish spatial prepositions in Chinese students’ acquisition of Spanish as a third language

description: This thesis investigates the acquisition of the spatial and figurative meanings of five Spanish spatial particles, namely sobre, encima, debajo, bajo and en, by a group of Chinese university students of Spanish as a foreign language at intermediate and upper-intermediate language levels. More specifically, this study aims to answer two questions. The first question considers the order of acquisition of prepositional meanings, that is, whether this is similar to a native language, with literal and more primary meanings acquired first and figurative ones later or, conversely, whether the pattern of acquisition is different to that found in a first language (Kemmerer, 2005; Lam, 2010). The second question of this research is to determine whether there are observable differences between the degree of acquisition and use of these prepositions in English compared to Spanish, and if so, what the characteristics of these differences are. To try to answer these questions, the performance of this group of participants in four behavioural tests is compared. The tests were a lexical identification task, a picture fill-in-the- blank task, a sentence generation task and a truth value judgment task. These tests were conducted both in Spanish, which the participants had begun to study at undergraduate level and English, which they had first been exposed to in school in a pre-puberty period. The results of this study indicate, first, that the acquisition of the literal and figurative meanings of the spatial particles in this study does not follow a pattern similar to that found in a native language. That is, meaning acquisition in a foreign language occurs in a parallel or simultaneous pattern. Furthermore, in a non-immersion context such as that of this study, the age at which students begin the study of a foreign language is not a decisive factor in determining the degree of mastery that students can obtain. The quantity and quality of the input students are exposed to; together with an appropriate methodology appear to be the most important factors in predicting the level of proficiency that can be reached.

description: We present a modified Altarelli and Feruglio $A_4$ model where an additional $A_4$ singlet-prime flavon is introduced. In this model, non-zero $θ_{13}$ is given by this additional $A_4$ singlet-prime flavon which breaks tri-bimaximal mixing. In the framework of the supersymmetry with $U(1)_R$ symmetry, we obtain vacuum expectation values (VEVs) and VEV alignments of flavons through driving fields. It is considered that flavon induces distinctive flavor violating process if flavon mass is light. Assuming mass of SUSY particles are sufficiently heavy so that the SUSY contributions can be negligible, we discuss the flavor violating Yukawa interaction through flavon exchange in the charged lepton sector. According to the potential analysis, the VEV of flavon breaks $A_4$ down to $Z_3$ in the charged lepton sector and relation among flavon masses is determined. Thanks for the residual $Z_3$ symmetry, many lepton flavor violating decay modes are forbidden except for $τ\rightarrow μμ\bar{e}$ and $τ\rightarrow e e \barμ$. A mass limit of the flavon from these three-body decay modes is $60$~GeV taking into account the current experimental lower bounds at the Belle experiment. In our model, we predict a ratio of the branching ratios $τ\rightarrow μμ\bar{e}$ and $τ\rightarrow e e \barμ$ by using known charged lepton masses. We also find that the production cross section for the flavon can be $\mathcal{O}(1)$ fb. Thus the flavon would be found at the LHC run 2 by searching for 4-tau lepton signal.

description: Phase diagrams play a primary role in the understanding of materials properties. For iron-based superconductors (Fe-SC), the correct definition of their phase diagrams is crucial because of the close interplay between their crystallo-chemical and magnetic properties, on one side, and the possible coexistence of magnetism and superconductivity, on the other. The two most difficult issues for understanding the Fe-SC phase diagrams are: 1) the origin of the structural transformation taking place during cooling and its relationship with magnetism; 2) the correct description of the region where a crossover between the magnetic and superconducting electronic ground states takes place. Hence a proper and accurate definition of the structural, magnetic and electronic phase boundaries provides an extremely powerful tool for material scientists. For this reason, an exact definition of the thermodynamic phase fields characterizing the different structural and physical properties involved is needed, although it is not easy to obtain in many cases. Moreover, physical properties can often be strongly dependent on the occurrence of micro-structural and other local-scale features (lattice micro-strain, chemical fluctuations, domain walls, grain boundaries, defects), which, as a rule, are not described in a structural phase diagram. In this review, we critically summarize the results for the most studied 11-, 122- and 1111-type compound systems, providing a correlation between experimental evidence and theory.
Bundling occupational safety with harm reduction information as a feasible method for improving police receptiveness to syringe access programs: evidence from three U.S. cities

description: Abstract Introduction In light of overwhelming evidence that access to sterile injection equipment reduces incidence of injection-attributable bloodborne disease without encouraging drug use, many localities have authorized sterile syringe access programs (SAPs), including syringe exchange and pharmacy-based initiatives. Even where such interventions are clearly legal, many law enforcement officers are unaware of the public health benefits and legal status of these programs and may continue to treat the possession of injection equipment as illegal and program participation as a marker of illegal behavior. Law enforcement practice can impede SAP utilization and may increase the risk of needlestick injury (NSI) among law enforcement personnel. Many SAPs conduct little or no outreach to law enforcement, in part because they perceive law enforcement actors as unreceptive to health-promotion programs targeting drug users. Case description We report on a brief training intervention for law enforcement personnel designed to increase officer knowledge of and positive attitudes towards SAPs by bundling content that addresses officer concerns about infectious disease and occupational safety with information about the legality and public health benefits of these programs. Pilot trainings using this bundled curriculum were conducted with approximately 600 officers in three US cities. Discussion and evaluation Law enforcement officers were generally receptive to receiving information about SAPs through the bundled curriculum. The trainings led to better communication and collaboration between SAP and law enforcement personnel, providing a valuable platform for better harmonization of law enforcement and public health activities targeting injection drug users. Conclusion The experience in these three cities suggests that a harm reduction training curriculum that bundles strategies for increasing officer occupational safety with information about the legality and public health benefits of SAPs can be well received by law enforcement personnel and can lead to better communication and collaboration between law enforcement and harm reduction actors. Further study is indicated to assess whether such a bundled curriculum is effective in changing officer attitudes and beliefs and reducing health risks to officers and injection drug users, as well as broader benefits to the community at large.

description: We investigate the dynamical stability of the Kepler-60 planetary system with three super-Earths. We first determine their orbital elements and masses by Transit Timing Variation (TTV) data spanning quarters Q1-Q16 of the KEPLER mission. The system is dynamically active but the TTV data constrain masses to ~4 Earth masses and orbits in safely wide stable zones. The observations prefer two types of solutions. The true three-body Laplace MMR exhibits the critical angle librating around 45 degrees and aligned apsides of the inner and outer pair of planets. In the Laplace MMR formed through a chain of two-planet 5:4 and 4:3 MMRs, all critical angles librate with small amplitudes of ~30 degrees and apsidal lines in planet's pairs are anti-aligned. The system is simultaneously locked in a three-body MMR with librations amplitude of ~10 degrees. The true Laplace MMR can evolve towards a chain of two-body MMRs in the presence of planetary migration. Therefore the three-body MMR formed in this way seems to be more likely state of the system. However, the true three-body MMR cannot be disregarded a priori and it remains a puzzling configuration that may challenge the planet formation theory.

description: AbstractBackgroundComparative characterization of genome-wide transcriptional changes during infection can help elucidate the mechanisms underlying host susceptibility. In this study, transcriptional profiling of the mouse colon was carried out in two cognate lines of mice that differ in their response to Citrobacter rodentium infection; susceptible inbred FVB/N and resistant outbred Swiss Webster mice. Gene expression in the distal colon was determined prior to infection, and at 4 and 9 days post-inoculation using a whole mouse genome Affymetrix array. ResultsComputational analysis identified 462 probe sets more than 2-fold differentially expressed between uninoculated resistant and susceptible mice. In response to C. rodentium infection, 5,123 probe sets were differentially expressed in one or both lines of mice. Microarray data were validated by quantitative real time RT-PCR for 35 selected genes and were found to have a 94% concordance rate. Transcripts represented by 1,547 probe sets, were differentially expressed between susceptible and resistant mice regardless of infection status, a host effect. Genes associated with transport were over-represented to a greater extent than even immune response-related genes. Electrolyte analysis revealed reduction in serum levels of chloride and sodium in susceptible animals. ConclusionThe results support the hypothesis that mortality in C. rodentium-infected susceptible mice is associated with impaired intestinal ion transport and development of fatal fluid loss and dehydration. These studies contribute to our understanding of the pathogenesis of C. rodentium and suggest novel strategies for the prevention and treatment of diarrhea associated with intestinal bacterial infections.

description: The lithium abundance in turnoff stars of the old population of our Galaxy is remarkably constant in the metallicity interval -2.8\textless{}[Fe/H] \textless{}-2.0, defining a plateau. The Li abundance of these turnoff stars is clearly lower than the abundance predicted by the primordial nucleosynthesis in the frame of the standard Big Bang nucleosynthesis. Different scenarios have been proposed for explaining this discrepancy, along with the very low scatter of the lithium abundance around the plateau. The recently identified very high velocity star, WISE J072543.88-235119.7 appears to belong to the old Galactic population, and appears to be an extreme halo star on a bound, retrograde Galactic orbit. In this paper, we study the abundance ratios and, in particular the lithium abundance, in this star. The available spectra (ESO-Very Large Telescope) are analyzed and the abundances of Li, C, Na, Mg, Al, Si, Ca, Sc, Ti, Cr, Mn, Fe, Co, Ni, Sr and Ba are determined.The abundance ratios in WISE J072543.88-235119.7 are those typical of old turnoff stars. The lithium abundance in this star ~is in close agreement with the lithium abundance found in the metal-poor turnoff stars located at moderate distance from the Sun. This high velocity star confirms, in an extreme case, that the very small scatter of the lithium plateau persists independent of the dynamic and kinematic properties of the stars.

description: Abstract Background Pathological angiogenesis contributes to various ocular, malignant, and inflammatory disorders, emphasizing the need to understand this process more precisely on a molecular level. Previously we found that CIB1, a 22 kDa regulatory protein, plays a critical role in endothelial cell function, angiogenic growth factor-mediated cellular functions, PAK1 activation, MMP-2 expression, and in vivo ischemia-induced angiogenesis. Since pathological angiogenesis is highly dependent on many of these same processes, we hypothesized that CIB1 may also regulate tumor-induced angiogenesis. Methods To test this hypothesis, we allografted either murine B16 melanoma or Lewis lung carcinoma cells into WT and CIB1-KO mice, and monitored tumor growth, morphology, histology, and intra-tumoral microvessel density. Results Allografted melanoma tumors that developed in CIB1-KO mice were smaller in volume, had a distinct necrotic appearance, and had significantly less intra-tumoral microvessel density. Similarly, allografted Lewis lung carcinoma tumors in CIB1-KO mice were smaller in volume and mass, and appeared to have decreased perfusion. Intra-tumoral hemorrhage, necrosis, and perivascular fibrosis were also increased in tumors that developed in CIB1-KO mice. Conclusions These findings suggest that, in addition to its other functions, CIB1 plays a critical role in facilitating tumor growth and tumor-induced angiogenesis.

description: This is a practice-based Ph. D. in filmmaking and concerns the generation of a radical film practice. It is situated in the field of no-budget experimental film and video making and deploys a combination of deconstruction and critical perspectives of cultural production in the construction of its modus operandi. The contribution to knowledge is in two parts. First the bringing together in a film practice established and various knowledges from other areas; contemporary and historical experimental film and video, observational documentary and amateur film practices, specifically Home Movies, in connection to established but various extant modes of reading that material. The second part of the contribution to knowledge relates to the methodology underpinning this amalgamation of knowledges. This is enacted through the tri-partite positioning of the researcher as 'researcher', 'familymaker' and 'filmmaker'. From within those positional framings the submission has sought to utilize a politicization of contextualisation. The second part of the submission's contribution to knowledge can then be formulated as the advocacy of a committed contextualisation that treats the investigator's position as valid and crucial material for interrogation. The outcome is a film practice that does not rely on sporadic funding and vacillating public recognition but rather an ongoing, organic and sustainable film practice that arises from and is nourished by the contexts it seeks to critically engage in. This translates formally into two DVDs and 39,153 words. There are four chapters or 'Screenings' which are self-reflexive and imaginative interrogations of DVD I Home Movies Summer 2005 (13 mins) which take the form of fictionalised conversations. Screening 1, a conversation between the researcher and a senior academician interrogates the film practice in the context of academic, practice based research and outlines the relationship between the artefact and the written text as related objects of thinking. Screening 2, a conversation between the researcher and members of his family, investigates notions of the familial drawing on some feminist perspectives that query notions of representation. Screening 3, a conversation between the researcher and Media and Cultural Studies staff at the researcher's home institution, crossexamines the film practice in relation to a theoretical formulation of political resistance. Screening 4, a conversation between the researcher and other filmmaker colleagues, scrutinises formulations from historical and contemporary film practices and charts filmic influences upon the filmmaking itself DVD 2 (28 mins) contains five experimental Home Movies that work to illustrate the filmmaking evolution towards the principal Home Movie on DVD 1

description: Erwin Schrodinger famously and presciently ascribed the vehicle transmitting the hereditary information underlying life to an `aperiodic crystal'. We compare and contrast this, only later discovered to be stored in the linear biomolecule DNA, with the information bearing, layered quasi-one-dimensional materials investigated by the emerging field of chaotic crystallography. Despite differences in functionality, the same information measures capture structure and novelty in both, suggesting an intimate coherence between the information character of biotic and abiotic matter---a broadly applicable physics of information. We review layered solids and consider three examples of how information- and computation-theoretic techniques are being applied to understand their structure. In particular, (i) we review recent efforts to apply new kinds of information measures to quantify disordered crystals; (ii) we discuss the structure of ice I in information-theoretic terms; and (iii) we recount recent experimental results on tris(bicyclo[2.1.1]hexeno)benzene TBHB), showing how an information-theoretic analysis yields additional insight into its structure. We then illustrate a new Second Law of Thermodynamics that describes information processing in active low-dimensional materials, reviewing Maxwell's Demon and a new class of molecular devices that act as information catalysts. Lastly, we conclude by speculating on how these ideas from informational materials science may impact biology.

description: We present a method for quantum entanglement distribution over a so-called code-division-multiple-access network, in which two pairs of users share the same quantum channel to transmit information. The main idea of this method is to use different broad-band chaotic phase shifts, generated by electro-optic modulators (EOMs) and chaotic Colpitts circuits, to encode the information-bearing quantum signals coming from different users, and then recover the masked quantum signals at the receiver side by imposing opposite chaotic phase shifts. The chaotic phase shifts given to different pairs of users are almost uncorrelated due to the randomness of chaos and thus the quantum signals from different pair of users can be distinguished even when they are sent via the same quantum channel. It is shown that two maximally-entangled states can be generated between two pairs of users by our method mediated by bright coherent lights, which can be more easily implemented in experiments compared with single-photon lights. Our method is robust under the channel noises if only the decay rates of the information-bearing fields induced by the channel noises are not quite high. Our study opens up new perspectives for addressing and transmitting quantum information in future quantum networks.

description: The 2015 BC Education Plan discussed the important role technology would play in our students lives. Computational Thinking was one change made to BC’s New Curriculum to reflect the demands our students now face in a digital world. However, I believe, simply acknowledging the importance of computational thinking in the Education Plan and making it a curricular choice for educators to implement does not provide the majority of educators in BC the resources or background with which to effectively teach coding. Thus, the purpose of this project was to create a coding website resource to enable intermediate students and educators to help meet the strong curricular expectations of the BC Curriculum. To help do this, the Critical Challenge Question was posed, ‘How can intermediate students be engaged to deepen their learning through collaborative game design and coding?’ I believe the project website will provide a strong unit of study, however, each professional should always seek out additional skills and knowledge which they find additionally important. Therefore, professional development and personal learning is highly recommended for any teacher considering introducing coding to their students.

description: Abstract: Background Multiple breast cancer gene expression profiles have been developed that appear to provide similar abilities to predict outcome and may outperform clinical-pathologic criteria; however, the extent to which seemingly disparate profiles provide additive prognostic information is not known, nor do we know whether prognostic profiles perform equally across clinically defined breast cancer subtypes. We evaluated whether combining the prognostic powers of standard breast cancer clinical variables with a large set of gene expression signatures could improve on our ability to predict patient outcomes. Methods Using clinical-pathological variables and a collection of 323 gene expression "modules", including 115 previously published signatures, we build multivariate Cox proportional hazards models using a dataset of 550 node-negative systemically untreated breast cancer patients. Models predictive of pathological complete response (pCR) to neoadjuvant chemotherapy were also built using this approach. Results We identified statistically significant prognostic models for relapse-free survival (RFS) at 7 years for the entire population, and for the subgroups of patients with ER-positive, or Luminal tumors. Furthermore, we found that combined models that included both clinical and genomic parameters improved prognostication compared with models with either clinical or genomic variables alone. Finally, we were able to build statistically significant combined models for pathological complete response (pCR) predictions for the entire population. Conclusions Integration of gene expression signatures and clinical-pathological factors is an improved method over either variable type alone. Highly prognostic models could be created when using all patients, and for the subset of patients with lymph node-negative and ER-positive breast cancers. Other variables beyond gene expression and clinical-pathological variables, like gene mutation status or DNA copy number changes, will be needed to build robust prognostic models for ER-negative breast cancer patients. This combined clinical and genomics model approach can also be used to build predictors of therapy responsiveness, and could ultimately be applied to other tumor types.

description: The effect of out-of-plane orientational freedom on the orientational ordering properties of a monolayer of hard ellipsoids is studied using Parsons-Lee scaling approach and replica exchange Monte Carlo computer simulation. Prolate and oblate ellipsoids exhibit very different ordering properties, namely, the axes of revolution of prolate particles tend to lean out, while those of oblate ones prefer to lean into the confining plane. The driving mechanism of this is that the particles try to maximize the available free area on the confining surface, which can be achieved by minimizing the cross section areas of the particles with the plane. In the lack out-of-plane orientational freedom the monolayer of prolate particles is identical to a two-dimensional hard ellipse system, which undergoes an isotropic-nematic ordering transition with increasing density. With gradually switching on the out-of-plane orientational freedom the prolate particles lean out from the confining plane and a destabilisation of the in-plane isotropic-nematic phase transition is observed. The system of oblate particles behaves oppositely to that of prolates. It corresponds to a two-dimensional system of hard disks in the lack of out-of-plane freedom, while it behaves similar to that of hard ellipses in the freely rotating case.

description: Abstract
                Background
                Differences between dental students in terms of social, economic and cultural backgrounds are likely to impact their professional career plans. The aim of this study was to explore the professional career plans among final year dental students from different backgrounds at a single Middle Eastern institution (Jordan university of Science and Technology-JUST).
                Methods
                Fifth year dental students at JUST were invited to fill out a paper based self-administered questionnaire. Data was collected on students` demographics, their future career plans and the impact of social and economic changes on such plans, their interest in postgraduate studies and the specialty of choice in addition to the influence of a group of factors on that choice. Data was also collected on the value of non-academic workshops, guidance regarding career plans, participants` preferred pattern of work (full-time versus part-time) and retirement plans. Students were categorized according to their nationalities. Pearson’s chi squared test, one way ANOVA and post hoc tests were used to measure statistical significance between measured variables and backgrounds of participants. The level of significance was set at P ≤ 0.05.
                Results
                A total of 227 students completed the survey (response rate = 84%). 47% of the participants were Jordanians, 27% were Malaysians, 11% were from Gulf States (Saudi Arabia, Bahrain, Kuwait and Qatar), 10% were from conflict zones in the Middle East (Syria, Iraq, Palestine and Yemen) and 5% comprised students from other nationalities. Significant differences were found between students from different backgrounds in their funding sources (Chi square = 132, P < 0.01), practice plans (Chi square = 43, P < 0.01), the impact of social and economic changes on their career choices (Chi square = 34, P < 0.01), planned work pattern within the first 10 years post-graduation (chi square = 18, P < 0.05) and 10–20 years after graduation (69%, Chi square = 22, P < 0.01) and retirement plans (Chi square = 25, P < 0.05). Students from different nationalities agreed on most factors affecting their choice of a specialty, except for the reputation of the specialty (P < 0.05).
                Conclusion
                Several differences in career plans were found between dental students from variable backgrounds studying a single institution. Many of these disparities could reflect variations in socioeconomic backgrounds.

description: Spasticity is a common problem in stroke patients, 17-43% of stroke survivals are affected. Spasticity has a major impact on pain, functionality and QoL (Quality of live). Current therapies often have side effects or are insufficiently effective. There is an ongoing search for new, additional therapeutic options. In this regard, dry needling is also investigated as a potential treatment for post-stroke spasticity. However, can dry needling be safely applied in a population such as stroke patients who are frequently taking anticoagulants ?

description: Abstract Background Incarceration history is associated with lower rates of condom use and increased HIV risk. Less is known about duration of incarceration and multiple incarcerations’ impact on condom use post-release. Methods In the current study, we surveyed 1,416 adults in Mississippi about their incarceration history and sexual risk behaviors. Generalized estimating equations (GEE) were used to test associations between duration of incarceration, multiple incarcerations, socio-demographic factors, substance use, sexual behavior, and event level condom use at last sex. Results After adjusting for covariates, having been incarcerated for at least 6 months two or more times remained significantly associated with condomless sex. Conclusions This study found a strong, independent relationship between condom use and multiple, long-term incarceration events among patients in an urban STI clinic in the Deep South. The results suggest that duration of incarceration and multiple incarcerations have significant effects on sexual risk behaviors, underscoring the deleterious impact of long prison or jail sentences on population health. Our findings also suggest that correctional health care professionals and post-release providers might consider offering comprehensive sexual and reproductive health services and those providing community care should consider screening for previous incarceration as a marker of risk.

description: Abstract Background While US home cooking declined in the late twentieth century, it is unclear whether the trend has continued. This study examines home cooking from 2003 to 2016 by gender, educational attainment, and race/ethnicity. Methods Nationally representative data from the American Time Use Study from 2003 to 2016 and linear regression models were used to examine changes in the percent of adults aged 18–65 years who cook and their time spent cooking, with interactions to test for differential changes by demographic variables of gender, education, and race/ethnicity. Results Cooking increased overall from 2003 to 2016. The percent of college-educated men cooking increased from 37.9% in 2003 to 51.9% in 2016, but men with less than high school education who cook did not change (33.2% in 2016) (p < 0.05). College-educated women who cook increased from 64.7% in 2003 to 68.7% in 2016, while women with less than high school education had no change (72.3% in 2016) (p < 0.05). Women with less education spent more time cooking per day than high-educated women, but the reverse was true for men. Among men, the percent who cook increased for all race/ethnic groups except non-Hispanic blacks. Among women, only non-Hispanic whites increased in percent who cook. Among both men and women, non-Hispanic blacks had the lowest percentage who cooked, and non-Hispanic others spent the greatest amount of time cooking. Conclusions Home cooking in the United States is increasing, especially among men, though women still cook much more than men. Further research is needed to understand whether the heterogeneity in home cooking by educational attainment and race/ethnicity observed here contributes to diet-related disparities in the United States.
The role of the cytoskeleton in cell body enlargement, increased nuclear eccentricity and chromatolysis in axotomized spinal motor neurons

description: Abstract Background When spinal motor axons are injured, the nucleolus, nucleus and cell body of the injured cell transiently increase in size, the nucleus becomes more eccentrically placed, and the organization of polyribosomes into Nissl bodies is temporarily disrupted. The mechanisms for these classical morphological responses to axotomy have not been satisfactorily explained. Results In this study we address the role of the cell body cytoskeleton in these structural changes. We show that the cytoskeleton of uninjured lumbar motor neuron cell bodies maintains nucleolar, nuclear and cell body size and nuclear position. When isolated, the relatively insoluble cell body cytoskeleton contains Nissl bodies and lipofuscin granules. After axotomy, protein labeling increases markedly and the cytoskeleton enlarges, increasing nucleolar, nuclear and cell body size, as well as nuclear eccentricity. Nearly all of the protein mass that accumulates in the cell body after axotomy appears to be added to the cytoskeleton. Conclusion We conclude that axotomy causes the conjugate enlargement of the nucleolus, nucleus and cell body and increases nuclear eccentricity in spinal motor neurons by adding protein to the cytoskeleton. The change in nuclear position, we propose, occurs when cytoskeletal elements of the axon cannot enter the shortened axon and "dam up" between the nucleus and axon hillock. As a consequence, we suggest that Nissl body-free axonal cytoskeleton accumulates between the nucleus and axon, displaces Nissl body-containing cytoskeleton, and produces central chromatolysis in that region of the cell.

description: We discuss how a cyclic model for the flat universe can be constructively derived from Loop Quantum Gravity. This model has a lower bounce, at small values of the scale factor, which shares many similarities with that of Loop Quantum Cosmology. We find that quantum gravity corrections can be also relevant at energy densities much smaller than the Planckian one and that they can induce an upper bounce at large values of the scale factor.

description: Since preventing a pandemic is not possible, the preparedness of medical imaging and other health professionals will be essential. The substantial body of literature found not only established the adverse effects of COVID-19 on radiographers, but also demonstrated what was implemented indicating a level of preparedness. However, studies detailing combative strategies and readiness are scattered. This scoping review will map the empirical evidence relevant to pandemic preparedness of medical imaging departments during COVID-19. This will guide future research in the development of pandemic preparedness tools and resources for not only medical imaging professionals but also other health disciplines, to face the current pandemic and other potential future disease outbreaks.

Development of HPLC Techniques for the Analysis of Trace Metal Species in the Primary Coolant of a Pressurised Water Reactor

Year: 1988

description: The need to monitor corrosion products in the primary circuit of a pressurised water reactor (PWR), at a concentration of 10pg ml-li s discussed. A review of trace and ultra-trace metal analysis, relevant to the specific requirements imposed by primary coolant chemistry, indicated that high performance liquid chromatography (HPLC), coupled with preconcentration of sample was an ideal technique. A HPLC system was developed to determine trace metal species in simulated PWR primary coolant. - In order to achieve the desired detection limit an online preconcentration system had to be developed. Separations were performed on Aminex A9 and Benson BC-XI0 analytical" columns. Detection was by post column reaction with Eriochrome Black T and Calmagite Linear calibrations of 2.5-100ng of cobalt (the main species of interest), were achieved using up to 200ml samples. The detection limit for a 200ml sample was 10pg ml-¹. In order to achieve the desired aim of on-line collection of species at 300°ᶜ, the use of inorganic ion-exchangers is essential. A novel application, utilising the attractive features of the inorganic ion-exchangers titanium dioxide, zirconium dioxide, zirconium arsenophoshate and pore controlled glass beads, was developed for the preconcentration of trace metal species at temperature and pressure. The performance of these exchangers, at ambient and 300°ᶜ was assessed by their inclusion in the developed analytical system and by the use of radioisotopes. The particular emphasis during the development has been upon accuracy, reproducibility of recovery, stability of reagents and system contamination, studied by the use of radioisotopes and response to post column reagents. This study in conjunction with work carried out at Winfrith, resulted in a monitoring system that could follow changes in coolant chemistry, on deposition and release of metal species in simulated PWR water loops. On-line detection of cobalt at 11pg ml-¹ was recorded, something which previously could not be performed by other techniques.
