Abstract

In parallel with advances in the synthesis of solid-state ionic conductors, there is a need to understand the underlying mechanisms behind their improved ionic conductivities. This can be achieved by obtaining an atomic level picture of the interplay between the structure of materials and the resultant ionic diffusion processes. To this end, the structure and dynamics of Mg2+-stabilized rotor phase material γ-Na3PO4, characterized by neutron scattering, are detailed in this work. The Mg2+-stabilized rotor phase is found to be thermally stable from 4 to 650 K. However, signatures of orientational disorder of the phosphate anions are also evident in the average structure. Long-range Na+ self-diffusion was probed by quasi-elastic neutron scattering and subsequently modeled via a jump diffusion matrix with consideration of the phosphate anion rotations. The resultant diffusion model points directly to coupled anion-cation dynamics. Our approach highlights the importance of considering the whole system when developing an atomic level picture of structure and dynamics, which is critical in the rational design and optimization of energy materials.

Abstract

Recruitment of poliovirus (PV) RNA to the human ribosome requires the coordinated interaction of the viral internal ribosome entry site (IRES) and several host cellular initiation factors and IRES trans-acting factors (ITAFs). Attenuated PV Sabin strains contain point mutations in the PV IRES domain V (dV) that inhibit viral translation. Remarkably, attenuation is most apparent in cells of the central nervous system, but the molecular basis to explain this is poorly understood. The dV contains binding sites for eukaryotic initiation factor 4G (eIF4G) and polypyrimidine tract-binding protein (PTB). Impaired binding of these proteins to the mutant IRESs has been observed, but these effects have not been quantitated. We used a fluorescence anisotropy assay to reveal that the Sabin mutants reduce the equilibrium dissociation constants of eIF4G and PTB to the PV IRES by up to 6-fold. Using the most inhibitory Sabin 3 mutant, we used a real-time fluorescence helicase assay to show that the apparent affinity of an active eIF4G/4A/4B helicase complex for the IRES is reduced by 2.5-fold. The Sabin 3 mutant did not alter the maximum rate of eIF4A-dependent helicase activity, suggesting that this mutant primarily reduces the affinity, rather than activity, of the unwinding complex. To confirm this affinity model of attenuation, we show that eIF4G overexpression in HeLa cells overcomes the attenuation of a Sabin 3 mutant PV-luciferase replicon. Our study provides a quantitative framework for understanding the mechanism of PV Sabin attenuation and provides an explanation for the previously observed cell type-specific translational attenuation.

Abstract

Pediatric obstructive sleep apnea poses a significant health risk, with potential long‐term consequences on cardiovascular health. This study explores the dichotomous nature of neonatal cardiac response to chronic intermittent hypoxia (CIH) between males and females, aiming to fill a critical knowledge gap in the understanding of sex‐specific cardiovascular consequences of sleep apnea in early life. Neonates were exposed to CIH until p28 and underwent comprehensive in vivo physiological assessments, including whole‐body plethysmography, treadmill stress‐tests, and echocardiography. Results indicated that male CIH rats weighed 13.7% less than age‐matched control males (p = 0.0365), while females exhibited a mild yet significant increased respiratory drive during sleep (93.94 ± 0.84 vs. 95.31 ± 0.81;p = 0.02). Transcriptomic analysis of left ventricular tissue revealed a substantial sex‐based difference in the cardiac response to CIH, with males demonstrating a more pronounced alteration in gene expression compared to females (5986 vs. 3174 genes). The dysregulated miRNAs in males target metabolic genes, potentially predisposing the heart to altered metabolism and substrate utilization. Furthermore, CIH in males was associated with thinner left ventricular walls and dysregulation of genes involved in the cardiac action potential, possibly predisposing males to CIH‐related arrhythmia. These findings emphasize the importance of considering sex‐specific responses in understanding the cardiovascular implications of pediatric sleep apnea. [ABSTRACT FROM AUTHOR]

Abstract

Background: Triage is pivotal in intensive care for patient safety and resource allocation. The admission algorithm has been shown to correlate with the appropriateness of ICU admission and offer decision aid when facing challenges in times of scarce critical care resources. This study aimed to explore the development of a reference tool to support triage decisions for admission to the ICU. Methods: In this retrospective observational study, the Intensive Care Triage Score (ICTS) was generated as a reference to correlate with the triage decision made by clinical judgment. ICU admission would be advised for ICTS below 6. The primary outcome was ICU admission. The secondary outcomes included ICU, hospital, 90- day, and 1-year mortality. The receiver operating characteristic curve was used to assess the performance of ICTS. Results: A total of 1664 patients were included in the analysis. There were 1204 patients (72.4%) admitted to the ICU; 680 of 738 (92%) with ICTS below 6 were admitted to the ICU. The hospital mortality of the whole cohort was 25.1%; there was a positive correlation between ICTS and hospital mortality. The area under the receiver operating characteristic curve (AUC) of ICTS in predicting hospital mortality for all patients was 0.754 (95% CI 0.728-0.780). The correlation between ICTS and hospital mortality was observed in patients admitted and not admitted to the ICU. Conclusion: Developing a scoring system as a reference tool would be useful for ICU triage. [ABSTRACT FROM AUTHOR]

11. The Productive Vocabulary Development in the Written Chinese of the Hong Kong Cantonese-Speaking Children

Author

Cheung, Emily Yee Man

Abstract

This paper reports a longitudinal investigation into the productive vocabulary development in the written Chinese of the Cantonese-speaking elementary children in Hong Kong. Data gathering took place using two vocabulary tests which selected prescriptive vocabulary from the textbooks and the 2007 Vocabulary List. The two assessment tests also included vocabulary from the two classes of words in Chinese, namely, the content and the function words. Data were collected in a senior elementary class in 2008 and 2009 respectively. The phonological, orthographical, syntactic and semantic dimensions of the children's productive vocabulary knowledge in both year four and year five were examined. The longitudinal data of these four linguistic dimensions were scored under respective conditions. The results indicate that the syntactic dimension of the function words is the weakest aspect in vocabulary growth. This may suggest that the syntactic acquisition of the function words seems to take a longer time. Furthermore, two relatively independent aspects of vocabulary knowledge, namely, the phonological-orthographical and the syntactic-semantic, emerge in the vocabulary development.

Abstract

Although Cognitive Behavioural Therapy (CBT) is effective for 60% of adolescents with anxiety disorders, only 36% are in remission post-intervention. This indicates that more effective treatments are needed which should be reflected in the NICE guidelines. We hypothesised that Single-case experimental designs (SCEDs) may provide a framework for accelerating the development of novel interventions. The primary purpose of this review was to investigate whether SCEDs are currently followed by randomised controlled trials (RCTs) of CBT intervention for adolescent anxiety disorders named in the NICE guidelines. The secondary objective was to investigate whether using SCEDs prior to RCTs could be a helpful approach.

Abstract

The poor ionic conductivity of candidate solid-state electrolytes in comparison to their liquid counterparts is a critical challenge in the implementation of all solid-state batteries. A strategy that has been widely used to address this issue is the modification of solid-state ionic conductors via chemical doping. However, the complex resultant structures and the presence of secondary phases have meant that understanding how the improved ionic conductivity is achieved remains a challenge. The work in this thesis presents a strategy to characterise the structure and develop an atomic level picture of the ionic diffusion processes in modified solid-state ionic conductors using a combination of powder diffraction and quasi-elastic neutron scattering (QENS). In doing so, this work aims to demonstrate a way to better understand the interplay between the structure of materials and ionic transport and thus facilitate the rational design and optimisation of solid-state ionic conductors for energy applications.The first part of this thesis focuses on NASICON (Na3Zr2Si2PO12), which is among the best performing known solid-state sodium ion conductors. Using neutron powder diffraction (NPD), we present a targeted study characterising the sodium sites to elucidate how fast ionic conduction is achieved in this material. A comparative NPD and preliminary QENS study on Mg-doped NASICON is also presented with the aim of identifying the primary Mg2+ doping site and how this affects sodium diffusion.The second part of this work presents a detailed characterisation of the structure and dynamics of γ-Na3PO4 which is present as a secondary phase in Mg-doped NASICON. As a rotor phase material, γ-Na3PO4 exhibits rotational diffusion of the phosphate units which influences sodium long-range diffusion. Hence, in the development of a model to describe sodium long-range diffusion, we present a strategy which may be extended to characterise ionic diffusion in similar systems where it is necess

Abstract

The modified technology acceptance model was used to predict actual Blackboard usage (a web-based information system) in a sample of 57 Hong Kong student teachers whose mean age was 27.8 yr. (SD = 6.9). While the general form of the model was supported, Application-specific Self-efficacy was a more powerful predictor of system use than Behavioural Intention as predicted by the theory of reasoned action. Thus in this cultural and educational context, it has been shown that the model does not fully mediate the effect of Self-efficacy on System Use. Also, users' Enjoyment exerted considerable influence on the component variables of Usefulness and Ease of Use and on Application-specific Self-efficacy, thus indirectly influencing system usage. Consequently, efforts to gain students' acceptance and, therefore, use of information systems such as Blackboard must pay adequate attention to users' Self-efficacy and motivational variables such as Enjoyment.

32. Insights into the Fast Sodium Conductor NASICON and the Effects of Mg2+Doping on Na+Conductivity

Author

Abstract

Na super ionic CONductor (NASICON), Na1+xZr2SixP3–xO12, is an excellent solid-state electrolyte on account of its high sodium-ion conductivity, which can be further enhanced through chemical doping. However, the underlying sodium diffusion mechanism and how it is affected by chemical doping are not fully understood. This, in part, stems from the ambiguity between reported average structure models, where there is variation in the number and location of the sodium crystallographic sites. In this work, we present a neutron scattering study on monoclinic NASICON and Mg2+-doped NASICON, with a focus on the characterization of the sodium sites. Our difference Fourier maps show that the sodium sites have limited long-range order at temperatures as low as 3 K. In addition, our characterization of Mg2+-doped NASICON suggests that although Mg2+preferentially dopes the secondary Na3PO4phase rather than the bulk NASICON phase, its NASICON sodium sites are comparatively more diffuse. Furthermore, quasi-elastic neutron scattering data show broader spectra for the Mg-doped NASICON compared to NASICON at 300 K, supporting a more dynamic environment. We propose that the more diffuse character of the sodium sites arising from the introduction of Mg2+contributes to the improvement of ionic conductivity in Mg-doped NASICON near room temperature.

Abstract

In this thesis, a group of patients with multiple sclerosis who had heterogeneous lesion topography were studied using the technique of nerve excitability. Previously, Ng et al. (2008, 2013) found different changes in the excitability of motor and sensory peripheral axons in multiple sclerosis. The question then arose as to why these peripheral nerve abnormalities were present in the first place. At the same time, peripheral nerve abnormalities had also been detected in other central nervous system diseases such as stroke (Jankelowitz et al., 2007a; Huynh et al., 2013) and spinal cord injury (Lin et al., 2007; Boland et al., 2011). Twenty-four patients with multiple sclerosis were studied, consisting of three groups of patients divided based on where their lesions were predominantly located in the central nervous system: Brain, Spinal Cord and Mixed (brain and spinal cord group). The aim of this thesis was to firstly, reproduce the findings by Ng et al. (2008, 2013), and secondly, determine whether peripheral nerve excitability changes that were identified previously were due to the disease process itself (i.e. systemic inflammation) or due to lesion topography (i.e. downstream effect from the central nervous system) by comparing the findings of each group with the findings from those with stroke and spinal cord injury. The results were unexpected. The motor and sensory studies in this thesis did not reproduce the excitability findings reported by Ng et al. (2008, 2013) and there were no differences between subgroups, excluding topography of lesions as a major factor. In fact, nerve excitability results in patients with multiple sclerosis were found to be like those in healthy subjects. Reasons for the differences may be due to the current studied patient cohort having less severe disease with a higher proportion on arguably stronger immunomodulatory therapies. Future studies could be directed pursuing changes found by Ng et al. in larger and differently constituted subgroups of multiple sclerosis, perhaps dividing by patients by disability or by clinical phenotypes.

Abstract

The recent advancements in radiotherapy technologies have made delivery of the highly conformal dose to the target volume possible. With the increasing popularity of delivering high dose per fraction in modern radiotherapy schemes such as in stereotactic body radiotherapy and stereotactic body ablative therapy, high degree of treatment precision is essential. In order to achieve this, we have to overcome the potential difficulties caused by patient instability due to immobilization problems; patient anxiety and random motion due to prolonged treatment time; tumor deformation and baseline shift during a treatment course. This is even challenging for patients receiving radiotherapy in the chest and abdominal regions because it is affected by the patient's respiration which inevitably leads to tumor motion. Therefore, monitoring of intrafractional motion has become increasingly important in modern radiotherapy. Major intrafractional motion management strategies including integration of respiratory motion in treatment planning; breath-hold technique; forced shallow breathing with abdominal compression; respiratory gating and dynamic real-time tumor tracking have been developed. Successful intrafractional motion management is able to reduce the planning target margin and ensures planned dose delivery to the target and organs at risk. Meanwhile, the emergency of MRI-linear accelerator has facilitated radiation-free real-time monitoring of soft tissue during treatment and could be the future modality in motion management. This review article summarizes the various approaches that deal with intrafractional target, organs or patient motion with discussion of their advantages and limitations. In addition, the potential future advancements including MRI-based tumor tracking are also discussed. [ABSTRACT FROM AUTHOR]

Abstract

Behavioral Parent Training (BPT) is a well-established therapy that reduces child externalized behaviors and parent stress. Although BPT was originally developed for parents of children with defiant behaviors, the program’s key concepts are relevant to parenting all children. Since parents might not fully utilize BPT due to cost and program location, we created an online game as a low-cost, easily accessible alternative or complement to BPT. We tested the game with nineteen undergraduate students at the University of Maryland. The experimental group completed pretest survey on core BPT knowledge, played the game, and completed a BPT posttest, while the control group completed a pretest and posttest survey over a three week period. Participants in the experimental group also completed a survey to indicate their satisfaction with the overall program. The experimental group demonstrated significantly higher levels of BPT knowledge than the control group and high levels of satisfaction. This suggests that an interactive, online BPT platform is an engaging and accessible way for parents to learn key concepts.

Abstract

The gravitational exchange of two fluids of different density through a convergent-divergent contraction is considered. Two-layer exchange flow theory is extended to include frictional effects with an emphasis on the interfacial friction. The magnitude of the interfacial friction is found to be greater than previously suggested and may be vital to the analysis of exchange flows. Experiments modelling gravitational exchange flow through a convergent-divergent contraction were conducted in the hydraulics laboratory at the University of British Columbia to test the hydraulic solutions that have been developed on two-layer exchange flow. A comparison of the theoretical solutions and experimental results is made. Experiments conducted provide data for evaluating the theoretical findings and help in locating the hydraulic controls of the experiment along with quantifying the magnitude of interfacial friction coefficient. A comparison is made between numerous values obtained for the interfacial friction coefficients by previous investigators and the experimental results of the present study. Flow visualization is used to study the Kelvin-Helmholtz and Holmboe instabilities that form at the interface of the two layers.

Abstract

The optimal timing for renal replacement therapy initiation in septic acute kidney injury (AKI) remains controversial. This study investigates the impact of early versus late initiation of continuous renal replacement therapy (CRRT) on organ dysfunction among patients with septic shock and AKI. Patients were dichotomized into 'early' (simplified RIFLE Risk) or 'late' (simplified RIFLE Injury or Failure) CRRT initiation. Patients with chronic kidney disease stage 5 or those on long-term dialysis were excluded. Organ dysfunction was quantified by Sequential Organ Failure Assessment (SOFA) score. From January 2008 to June 2011, 120 patients fulfilled the inclusion criteria. Thirty-one (26%) underwent 'early' while 89 (74%) had 'late' CRRT. No significant difference was noted between groups on improvement of total SOFA/non-renal SOFA score or noradrenaline equivalent in the first 24 and 48 h after CRRT initiation. Dialysis requirement and mortality (at 28 days, 3 months and 6 months) did not differ. In conclusion, improvement of non-renal SOFA score 48 h after CRRT correlated with SOFA score on CRRT initiation ( P = 0.040) and APACHE IV risk of death ( P = 0.000), but not estimated glomerular filtration rate on CRRT initiation ( P = 0.377). Improvement of non-renal SOFA score correlated with SOFA score on CRRT initiation and APACHE IV risk of death. However, this retrospective review cannot identify any significant clinical benefit of early CRRT initiation in patients presenting with septic shock and AKI. [ABSTRACT FROM AUTHOR]

Abstract

In parallel with advances in the synthesis of solid-state ionic conductors, there is a need to understand the underlying mechanisms behind their improved ionic conductivities. This can be achieved by obtaining an atomic level picture of the interplay between the structure of materials and the resultant ionic diffusion processes. To this end, the structure and dynamics of Mg 2+ -stabilized rotor phase material γ-Na 3 PO 4 , characterized by neutron scattering, are detailed in this work. The Mg 2+ -stabilized rotor phase is found to be thermally stable from 4 to 650 K. However, signatures of orientational disorder of the phosphate anions are also evident in the average structure. Long-range Na + self-diffusion was probed by quasi-elastic neutron scattering and subsequently modeled via a jump diffusion matrix with consideration of the phosphate anion rotations. The resultant diffusion model points directly to coupled anion-cation dynamics. Our approach highlights the importance of considering the whole system when developing an atomic level picture of structure and dynamics, which is critical in the rational design and optimization of energy materials.
