Author

Herkes, Sharon M., Gordon-Thomson, Clare, Arnaiz, sabel A., Muir, Meloni M., Wardak, Dewa, and King, Dane A.

Abstract

A digital mobile card-matching game called eFlip was developed to assist second-year undergraduate medical science students to learn core content and understand key associations in physiology. Our team developed customized content of core physiological associations, of increasing difficulty, for upload on a generic card-matching platform. The generic game was extended with add-ons coded to allow identification and access of student usage data for students who consented to have their game usage linked to academic performance such as final course marks and grades. Here, we describe the development of the eFlip game content, the student usage profile, and the game's impact on learning. Students were invited to use eFlip prior to and during the final examination period. Of those who used eFlip, 152 students consented to participate in a study of game use on learning performance outcomes. Within the students who consented, 74 played the game and 78 did not play the game (nonplayers). The mean course mark of the students who played the game [69.57%; 95% confidence level (CI) (67.22, 71.92)] was higher than that of the nonplayers [65.33%; 95% CI (62.67, 67.99)] (P = 0.02). Playing eFlip was also associated with reduced failure rates in students who played the game (1% failure rate) compared with the students who did not play the game (10% failure rate; P = 0.02). The number of games played by students peaked just prior to the course final examination. Overall, students who chose to play eFlip demonstrated improved grades that were associated with a higher probability of passing the physiology course.

Abstract

Susceptibility to photoimmune suppression and photocarcinogenesis is greater in male than in female humans and mice and is exacerbated in female estrogen receptor-beta knockout (ER-β−/−) mice. We previously reported that the active vitamin D hormone, 1,25-dihydroxyvitamin D3 (1,25(OH)2D), applied topically protects against the ultraviolet radiation (UV) induction of cutaneous cyclobutane pyrimidine dimers (CPDs) and the suppression of contact hypersensitivity (CHS) in female mice. Here, we compare these responses in female versus male Skh:hr1 mice, in ER-β−/−/−− versus wild-type C57BL/6 mice, and in female ER-blockaded Skh:hr1 mice. The induction of CPDs was significantly greater in male than female Skh:hr1 mice and was more effectively reduced by 1,25(OH)2D in female Skh:hr1 and C57BL/6 mice than in male Skh:hr1 or ER-β−/− mice, respectively. This correlated with the reduced sunburn inflammation due to 1,25(OH)2D in female but not male Skh:hr1 mice. Furthermore, although 1,25(OH)2D alone dose-dependently suppressed basal CHS responses in male Skh:hr1 and ER-β−/− mice, UV-induced immunosuppression was universally observed. In female Skh:hr1 and C57BL/6 mice, the immunosuppression was decreased by 1,25(OH)2D dose-dependently, but not in male Skh:hr1, ER-β−/−, or ER-blockaded mice. These results reveal a sex bias in genetic, inflammatory, and immune photoprotection by 1,25(OH)2D favoring female mice that is dependent on the presence of ER-β.

6. A test of remote memory for use with Australian subjects

Author

Gordon-Thomson, F J

Abstract

Memory impairment is commonly associated with ageing and is one of the most prominent clinical features of senile dementia. In contrast to normal elderly subjects, demented subjects show a relative preservation of remote memory; although unable to recall recent events, they are able to reproduce more distant recollections. This has been illustrated using a variety of remote memory tests. Most remote memory tests are, however, open to criticism due to the many methodological problems inherent in their design. This review examines some of the remote memory tests which are available for use in clinical and research settings. Directions for future research are discussed.

7. Skeletal Muscle and the Maintenance of Vitamin D Status

Abstract

Vitamin D, unlike the micronutrients, vitamins A, E, and K, is largely obtained not from food, but by the action of solar ultraviolet (UV) light on its precursor, 7-dehydrocholesterol, in skin. With the decline in UV light intensity in winter, most skin production of vitamin D occurs in summer. Since no defined storage organ or tissue has been found for vitamin D, it has been assumed that an adequate vitamin D status in winter can only be maintained by oral supplementation. Skeletal muscle cells have now been shown to incorporate the vitamin D-binding protein (DBP) from blood into the cell cytoplasm where it binds to cytoplasmic actin. This intracellular DBP provides an array of specific binding sites for 25-hydroxyvitamin D (25(OH)D), which diffuses into the cell from the extracellular fluid. When intracellular DBP undergoes proteolytic breakdown, the bound 25(OH)D is then released and diffuses back into the blood. This uptake and release of 25(OH)D by muscle accounts for the very long half-life of this metabolite in the circulation. Since 25(OH)D concentration in the blood declines in winter, its cycling in and out of muscle cells appears to be upregulated. Parathyroid hormone is the most likely factor enhancing the repeated cycling of 25(OH)D between skeletal muscle and blood. This mechanism appears to have evolved to maintain an adequate vitamin D status in winter.

10. Vitamin D and Death by Sunshine

Author

vitamin D, 1,25-dihydroxyvitamin D3, ultraviolet radiation, sunburn cells, cyclobutane pyrimidine dimers, p53, nitric oxide, MAPK, AKT, Biology (General), QH301-705.5, Chemistry, QD1-999
Abstract

Exposure to sunlight is the major cause of skin cancer. Ultraviolet radiation (UV) from the sun causes damage to DNA by direct absorption and can cause skin cell death. UV also causes production of reactive oxygen species that may interact with DNA to indirectly cause oxidative DNA damage. UV increases accumulation of p53 in skin cells, which upregulates repair genes but promotes death of irreparably damaged cells. A benefit of sunlight is vitamin D, which is formed following exposure of 7-dehydrocholesterol in skin cells to UV. The relatively inert vitamin D is metabolized to various biologically active compounds, including 1,25-dihydroxyvitamin D3. Therapeutic use of vitamin D compounds has proven beneficial in several cancer types, but more recently these compounds have been shown to prevent UV-induced cell death and DNA damage in human skin cells. Here, we discuss the effects of vitamin D compounds in skin cells that have been exposed to UV. Specifically, we examine the various signaling pathways involved in the vitamin D-induced protection of skin cells from UV.

Abstract

Located in the west desert of Utah, USA, the Telescope Array experiment is the largest ultra-high energy cosmic ray observatory in the northern hemisphere. It consists of two types of detectors: scintillator surface detectors (SDs) and air fluorescence detectors (FDs). A total of 507 SDs consisting of two-layer plastic scintillation counters is deployed with 1.2 km spacing, making measurements over an area of approximately 700 km2. There are 3 FD stations, having 38 fluorescence telescopes viewing 3°–31°in elevation, overlooking the SD array. In this work, we update the Telescope Array energy spectrum as measured by the SD array for 14 years. We verify the linearity in TA SD energy reconstruction using three different energy comparisons: Monte Carlo comparison, FD/SD comparison, and Constant Intensity Cut method. The spectral features of ankle, softening, and GZK cutoff are seen in 14 years of TA SD data. Also, we consistently observe that the cutoff energy depends on declination.

Abstract

The Telescope Array (TA) experiment, the largest observatory studying ultra-high energy cosmic rays in the northern hemisphere, has reported evidence for two medium-scale anisotropies. The first, known as the TA hotspot, is an excess in the arrival direction distribution for events with energies greater than 5.7 × 1019 eV. More recently, an additional excess of events with energies greater than 1019.4 eV appearing in the direction of the Perseus-Pisces supercluster has been named the PPSC excess. In this presentation, we will update the status of the TA hotspot and the PPSC excess results using the most recent data measured by the TA surface detector array.

Abstract

The Telescope Array (TA) experiment, the largest observatory studying ultrahigh energy cosmic rays in the northern hemisphere, has reported an excess in the arrival direction distribution for events with energies above $5.7 \times 10^{19}~{\rm eV}$, called the hotspot. We report here the latest results of the TA hotspot using the most recent data measured by the TA surface detector array, which is more than doubled exposure since the first publication; the hotspot still exists with 3 sigma post-trial significance. By using an oversampling search with a $20^\circ$-circle, similar to the study of the hotspot, we find an additional excess of events at slightly lower energies. The Perseus-Pisces supercluster lies at the location of the new excess. Assuming this structure is responsible for the excess, we conducted a statistical analysis to verify the correlation between observed events and the members of the Perseus-Pisces supercluster.

Abstract

The paper studies the performance of a novel generator, consisting of a ball tightly sandwiched between two dielectric elastomeric membranes for energy harvesting. The membranes are built into a housing subjected to external ambient random vibrations, so that the relative motion between the ball and the membranes deforms the latter allowing energy conversion. A dynamic model of the nonlinear mechanical and electrical behaviour of the device is presented, and a novel approach for estimating the mean output energy of the device is developed. An explicit analytical formula for the mean output power, derived and presented for the first time, allows comparing the generator performance depending on the level of nonlinearity and the membranes deformation rate. A comparison of the generator performance for the linear and nonlinear device properties is demonstrated. The numerical results of the Monte-Carlo simulations are presented and agreed well with the derived analytical estimation.

Abstract

The paper considers electrostatic energy conversion from ambient vibrations using dielectric elastomers. A novel device for vibration energy harvesting is proposed, studied and compared with a vibroimpact device previously investigated by the authors for the same purpose. The nonlinear dynamic behaviour of the new device is explored numerically and the results presented indicate excellent energy harvesting capabilities with an energy density of 9.15 J∕kg. The proposed device particularly benefits from stiffness nonlinearity of its dielectric membranes as is demonstrated by comparison with their linear behaviour. The influence of nonlinearity is further investigated, with results compared against recent reports on dielectric elastomer energy harvesting and other forms of vibration energy harvesting. Two electrical schemes that can be used for the electrostatic energy conversion are also introduced and compared in terms of their suitability for the proposed device.

Abstract

Recent media reports and anecdotal evidence from across a range of sports has led to questions about whether welfare and safety really are being given the priority they deserve in elite sport. At a time of success for British sport in terms of medals, championships, and profile, this raises challenging questions about whether the current balance between welfare and winning is right and what we are prepared to accept as a nation (Grey-Thompson, 2017, p. 4). This chapter aims to introduce the term duty of care and consider its scope within sport. It will introduce mental health and abuse in sport as two risk factors, which can threaten athlete well-being in performance environments, and finally introduce safeguarding as a step toward promoting a duty of care for all in sport. Practical recommendations are made in order to support people and organizations working toward achieving a duty of care for all.

Abstract

Susceptibility to photoimmune suppression and photocarcinogenesis is greater in male than in female humans and mice and is exacerbated in female estrogen receptor-beta knockout (ER-β-/-) mice. We previously reported that the active vitamin D hormone, 1,25-dihydroxyvitamin D3 (1,25(OH)2D) applied topically protects against ultraviolet radiation (UV)-induction of cutaneous cyclobutane pyrimidine dimers (CPDs) and suppression of contact hypersensitivity (CHS) in female mice. Here we compare these responses in female versus male Skh:hr1 mice, in ER-β-/- versus wild type C57BL/6 mice, and in female ER-blockaded Skh:hr1 mice. Induction of CPDs was significantly greater in male than female Skh:hr1 mice and was more effectively reduced by 1,25(OH)2D in female Skh:hr1 and C57BL/6 mice, than in male Skh:hr1 or ER-β-/- mice respectively. This correlated with reduced sunburn inflammation by 1,25(OH)2D in female but not male Skh:hr1 mice. Furthermore, although 1,25(OH)2D alone dose-dependently suppressed basal CHS responses in male Skh:hr1 and ER-β-/- mice, UV-induced immunosuppression was universally observed. In female Skh:hr1 and C57BL/6 mice, the immunosuppression was decreased by 1,25(OH)2D dose-dependently, but not in male Skh:hr1, ER-β-/- or ER-blockaded mice. These results reveal a sex bias in genetic, inflammatory and immune photoprotection by 1,25(OH)2D favoring female mice, that is dependent on the presence of ER-β.

Abstract

In this paper we report the first close, high-resolution observations of downward-directed terrestrial gamma-ray flashes (TGFs) detected by the large-area Telescope Array cosmic ray observatory, obtained in conjunction with broadband VHF interferometer and fast electric field change measurements of the parent discharge. The results show that the TGFs occur during strong initial breakdown pulses (IBPs) in the first few milliseconds of negative cloud-to-ground and low-altitude intracloud flashes, and that the IBPs are produced by a newly-identified streamer-based discharge process called fast negative breakdown. The observations indicate the relativistic runaway electron avalanches (RREAs) responsible for producing the TGFs are initiated by embedded spark-like transient conducting events (TCEs) within the fast streamer system, and potentially also by individual fast streamers themselves. The TCEs are inferred to be the cause of impulsive sub-pulses that are characteristic features of classic IBP sferics. Additional development of the avalanches would be facilitated by the enhanced electric field ahead of the advancing front of the fast negative breakdown. In addition to showing the nature of IBPs and their enigmatic sub-pulses, the observations also provide a possible explanation for the unsolved question of how the streamer to leader transition occurs during the initial negative breakdown, namely as a result of strong currents flowing in the final stage of successive IBPs, extending backward through both the IBP itself and the negative streamer breakdown preceding the IBP., Comment: Typo fixed and reference added.
