Epigenetic signatures of prenatal alcohol exposure
Creators: name: Lussier, Alexandre André
Publisher: name: University of British Columbia
Year: 2018

description: Prenatal alcohol exposure (PAE) can alter the development, function, and regulation of neurobiological and physiological systems, causing lasting cognitive alterations, behavioral deficits, immune dysfunction, and increased vulnerability to mental health problems. In humans, the spectrum of these deficits is known as fetal alcohol spectrum disorder (FASD). Although the molecular underpinnings are not fully elucidated, epigenetic mechanisms are a prime candidate for the programming of physiological systems by PAE, as they may bridge environmental stimuli and neurodevelopmental outcomes. DNA methylation is also emerging as a potential biomarker of early-life events, which may aid in earlier FASD diagnoses. Thus, my overarching aim was to identify epigenetic mechanisms that may contribute to the deficits associated with FASD and act as biosignatures of PAE. Specifically, I used genome-wide approaches to assess underlying gene expression programs and epigenomic profiles in a rat model of PAE and clinical cohorts of individuals with FASD. In the rat model, I identified alterations to gene expression programs in the brain of adult PAE females under steady-state and immune challenge conditions. Building on these long-term alterations to transcriptomic programs, I identified altered DNA methylation patterns persisting from birth to weaning in the hypothalamus PAE animals, suggestive of early reprogramming of neurobiological systems. In parallel, I found concordant alterations to DNA methylation profiles in the hypothalamus and white blood cells of PAE animals, which may reflect systemic effects and potential biomarkers of PAE. To complement the animal model, I also investigated DNA methylation patterns in two clinical cohorts of FASD, where I identified an epigenetic signature of FASD in buccal epithelial cells. As these results raised the possibility of an epigenetic biomarker, I investigated the relevance of DNA methylation as a diagnostic method for PAE, and successfully generated a predictive algorithm that could classify individuals with FASD versus controls. Overall, these findings provide evidence for the biological embedding of PAE’s effects through changes in gene expression and DNA methylation, while setting the stage for the development of novel biomarkers. Ultimately, these may aid in the development of targeted interventions and early screening tools to mitigate the deficits associated with FASD.

description: Two finely segmented and very compact calorimeters are foreseen for the instrumentation of the very forward region of the ILC and the CLIC detectors; a luminometer to measure the rate of low angle Bhabha scattering events with a precision better than $10^{-3}$ and, at lower polar angles, a detector for fast luminosity estimate. Both devices will improve the hermeticity of the detector in searches for new particles. Due to the expected high occupancy, fast front-end electronics is needed. The calorimeter closest to the beampipe will be hit by a large amount of beamstrahlung remnants, so that radiation hard sensors are required. Results on the performance of the sensor and readout electronics prototypes are summarized.

description: This paper analyzes the persistence of environmental, social, and governance (ESG)-scores in socially responsible (SR) mutual funds. ESG-scores can be used as a measure for the level of social responsibility of an SR mutual fund. It is shown that ESG-scores persist for approximately two years. However, the persistence of the ESG-scores is terminated after approximately three years. This implies that value-driven investors of SR mutual funds who seek high-ESG investments cannot rely upon a long-term continuation of high ESG-scores and thus need to rebalance their portfolio from time to time. The lack of long-term persistence in the ESG-scores is caused by changes in the holdings of the SR mutual funds.

description: A fundamental problem in computational geometry is to compute an obstacle-avoiding Euclidean shortest path between two points in the plane. The case of this problem on polygonal obstacles is well studied. In this paper, we consider the problem version on curved obstacles, commonly modeled as splinegons. A splinegon can be viewed as replacing each edge of a polygon by a convex curved edge (polygons are special splinegons). Each curved edge is assumed to be of O(1) complexity. Given in the plane two points s and t and a set of $h$ pairwise disjoint splinegons with a total of $n$ vertices, we compute a shortest s-to-t path avoiding the splinegons, in $O(n+h\log^{1+ε}h+k)$ time, where k is a parameter sensitive to the structures of the input splinegons and is upper-bounded by $O(h^2)$. In particular, when all splinegons are convex, $k$ is proportional to the number of common tangents in the free space (called "free common tangents") among the splinegons. We develop techniques for solving the problem on the general (non-convex) splinegon domain, which also improve several previous results. In particular, our techniques produce an optimal output-sensitive algorithm for a basic visibility problem of computing all free common tangents among $h$ pairwise disjoint convex splinegons with a total of $n$ vertices. Our algorithm runs in $O(n+h\log h+k)$ time and $O(n)$ space, where $k$ is the number of all free common tangents. Even for the special case where all splinegons are convex polygons, the previously best algorithm for this visibility problem takes $O(n+h^2\log n)$ time.

Subjects: subject: 780 Musik

description: The two pieces introduced and briefly discussed in this article have so far remained unnoticed because of the manner of their notation. In each case pieces of two-voice polyphony were notated with the two voices separate, instead of in the score notation which has been usual since, roughly, the second half of the twelfth century. In the one case, the sequence Magnus deus in universa terra in a manuscript from Marchiennes of the fourteenth century, a second voice was added at the back of the book in which the usual melody had already been recorded. In the other case, the song Ad honorem regis summi in the so-called Codex Calixtinus, the two voices are notated successively, verse 1 of the text being given with the first voice, verse 2 with the second voice.

description: In the framework of cavity QED, we propose a practical scheme to purify dynamically a bipartite entangled state using short chains of atoms coupled to high-finesse optical cavities. In contrast to conventional entanglement purification protocols, we avoid CNOT gates, thus reducing complicated pulse sequences and superfluous qubit operations. Our interaction scheme works in a deterministic way, and together with entanglement distribution and swapping, opens a route towards efficient quantum repeaters for long-distance quantum communication.

description: In task switching studies, pre-cuing of the upcoming task improves performance, indicating preparatory activation of the upcoming task-set, and/or inhibition of the previous task-set. To further investigate cue-based task preparation, the authors presented both valid and invalid task cues in a task switching experiment involving three tasks. Consistent with previous findings, a validity effect in terms of higher reaction times on invalidly compared to validly cued tasks was obtained. However, this validity effect was reduced following invalidly cued trials, suggesting dynamic adjustment in terms of decreased cue-based preparation after being misled. Performance was particularly impaired when the current task was the one that was invalidly cued on the preceding trial. This finding may reflect either particular reluctance to prepare or persisting inhibition of the erroneously prepared task-set from the pre-trial.

The neurophysiology of sensorimotor integration in healthy aging and chronic stroke
Creators: name: Brown, Katlyn Elizabeth
Publisher: name: University of British Columbia
Year: 2017

description: Background: General decline in motor performance is often cited in healthy aging, and motor deficits persist into the chronic phase of stroke recovery. Abnormalities in sensorimotor integration may underlie these motor deficits; however, the effect of aging and chronic stroke on sensorimotor integration neurophysiology is not well understood. Further, investigation into the plasticity of sensorimotor integration is important to establish in populations experiencing sensorimotor decline. Methods: The overall objective of this thesis was to comprehensively understand the neurophysiology of sensorimotor integration, including the influence of aging and chronic stroke on sensorimotor integration and the reliability of common neurophysiological measures. The first research chapter (Chapter 2) explores age and stroke-related differences in measures of indirect sensorimotor integration. Chapters 3 and 4 investigate baseline differences in measures of direct sensorimotor integration induced by aging and chronic stroke, respectively. Further, they use an intervention to index plasticity of sensorimotor integration in these populations. The final chapter (Chapter 5) addresses the reliability of a variety of neurophysiological methods used to examine somatosensory and motor cortical excitability, as well as sensorimotor integration. Summary of Findings: In Chapter 2, older individuals and individuals with chronic stroke had reduced short-latency afferent inhibition, compared to younger individuals suggesting the difference is largely driven by age-related factors. Greater disinhibition post-stroke related to worse motor function and impairment. Chapter 3 showed that measures of direct sensorimotor integration are less susceptible to age-related changes than measures of indirect sensorimotor integration. Sensory training altered direct but not indirect sensorimotor integration, suggesting independent modulation of separate anatomical pathways of sensorimotor integration. Chapter 4 highlighted differences in direct sensorimotor integration between individuals with chronic stroke and older individuals such that vibration had less of an impact on baseline motor cortex excitability in individuals post-stroke and the intracortical response to sensory training was reduced. Chapter 5 showed high reliability in transcranial magnetic stimulation thresholds, the amplitudes of evoked potentials elicited at high stimulation intensities, and latency-based measures. Conclusions: This dissertation contributes new knowledge to the impact of aging and chronic stroke on sensorimotor integration and the reliability of the measures used to quantify sensorimotor integration.

Mental Rotation Performance in Male Soccer Players

Subjects: subject: 150 Psychologie

description: It is the main goal of this study to investigate the visual-spatial cognition in male soccer players. Forty males (20 soccer players and 20 non-athletes) solved a chronometric mental rotation task with both cubed and embodied figures (human figures, body postures). The results confirm previous results that all participants had a lower mental rotation speed for cube figures compared to embodied figures and a higher error rate for cube figures, but only at angular disparities greater than 90°. It is a new finding that soccer–players showed a faster reaction time for embodied stimuli. Because rotation speed did not differ between soccer-players and non-athletes this finding cannot be attributed to the mental rotation process itself but instead to differences in one of the following processes which are involved in a mental rotation task: the encoding process, the maintanence of readiness, or the motor process. The results are discussed against the background of the influence on longterm physical activity on mental rotation and the context of embodied cognition.
How positive affect modulates proactive control: reduced usage of informative cues under positive affect with low arousal

Subjects: subject: cognitive control, positive affect, arousal
subject: 150 Psychologie

description: An example of proactive control is the usage of informative cues to prepare for an upcoming task. Here the authors will present data from a series of three experiments, showing that positive affect along with low arousal reduces proactive control in form of a reduced reliance on informative cues. In three affect groups, neutral or positive affective picture stimuli with low and high arousal preceded every trial. In Experiments 1 and 2, using a simple response cueing paradigm with informative cues (66% cue validity), a reduced cue validity effect (CVE) was found under positive affect with low arousal. To test the robustness of the effect and to see whether reactive control is also modulated by positive affect, Experiment 3 used a cued task switching paradigm with predicitive cues (75% cue validity). As expected, a reduced CVE was again found specifically in the positive affect condition with low arousal, but only for task repetitions. Furthermore, there was no difference in switch costs between affect groups (with and without task cues). Taken together, the reduced CVE indicates that positive affect with low arousal reduces proactive control, while comparable switch costs suggest that there is no influence of positive affect on reactive control.

description: We present deep XMM observations and ESO WFI optical imaging of two X-ray-selected fossil group candidates, RXCJ0216.7-4749 and RXCJ2315.7-0222. Using the X-ray data, we derive total mass profiles under the hydrostatic equilibrium assumption. The central regions of RXCJ0216.7-4749 are found to be dominated by an X-ray bright AGN, and although we derive a mass profile, uncertainties are large and the constraints are significantly weakened due to the presence of the central source. The total mass profile of RXCJ2315.7-0222 is of high quality, being measured in fifteen bins from [0.075 - 0.75]R500 and containing three data points interior to 30 kpc, allowing comprehensive investigation of its properties. We probe several mass models based on the standard NFW profile or on the Sersic-like model recently suggested by high-resolution N-body simulations. We find that the addition of a stellar component due to the presence of the central galaxy is necessary for a good analytical model fit. In all mass profile models fitted, the mass concentration is not especially high compared to non-fossil systems. In addition, the modification of the dark matter halo by adiabatic contraction slightly improves the fit. However, our result depends critically on the choice of IMF used to convert galaxy luminosity to mass, which leads to a degeneracy between the central slope of the dark matter profile and the normalisation of the stellar component. While we argue on the basis of the range of M_*/L_R ratios that lower M_*/L_R ratios are preferred on physical grounds and that adiabatic contraction has thus operated in this system, better theoretical and observational convergence on this problem is needed to make further progess.

Investigations in Flatland : scanning tunnelling microscopy measurements of noble metal surface states and magnetic atoms on magnesium oxide
Creators: name: Macdonald, Andrew James
Publisher: name: University of British Columbia
Year: 2017

description: At the atomic scale, surfaces exhibit a rich variety of physical phenomena that can be probed using a scanning tunnelling microscope (STM). The STM measures the quantum tunnelling of electrons between a metallic tip and conducting sample and can be used to characterize the nanoscale surface. This thesis presents STM measurements taken at low-temperature in ultra-high vacuum, which are used to characterize two different nanoscale environments: the two-dimensional surface states of Ag(111) and Cu(111) and the magnetic moments of iron and cobalt atoms deposited on a thin-film of magnesium oxide. Fourier-transform scanning tunnelling spectroscopy (FT-STS) analysis of quasiparticle interference, created by impurity scattering on the surfaces of the noble metals Ag(111) and Cu(111), is used to compare the most common modes of acquiring FT-STS data and shows, through both experiment and simulations, that artifact features can arise that depend on how the STM tip height is stabilized throughout the course of the measurement. Such artifact features are similar to those arising from physical processes in the sample and are susceptible to misinterpretation in the analysis of FT-STS in a wide range of important materials. A prescription for characterizing and avoiding these artifacts is proposed, which details how to check for artifacts using measurement acquisition modes that do not depend on tip height as a function of lateral position and careful selection of the tunnelling energy. In a separate set of experiments a spin resonance technique is coupled to an STM to probe the spin states of individual iron atoms on a magnesium oxide bilayer. The magnetic interaction between the iron atoms and surrounding spin centres shows an inverse-cubic distance dependence at distances greater than one nanometre. This distance-dependence demonstrates that the spins are coupled via a magnetic dipole-dipole interaction. By characterizing this interaction and combining it with atomic manipulation techniques a new form of nanoscale magnetometry is invented. This nanoscale magnetometer can be combined with trilateration to probe the spin structure of individual atoms and nanoscale structures. The information gained characterizing these new forms of magnetic sensing sets the stage for the study of complex magnetic systems like molecular magnets.

description: We explore the properties of the low-temperature phase of the O($n$) loop model in two dimensions by means of transfer-matrix calculations and finite-size scaling. We determine the stability of this phase with respect to several kinds of perturbations, including cubic anisotropy, attraction between loop segments, double bonds and crossing bonds. In line with Coulomb gas predictions, cubic anisotropy and crossing bonds are found to be relevant and introduce crossover to different types of behavior. Whereas perturbations in the form of loop-loop attractions and double bonds are irrelevant, sufficiently strong perturbations of these types induce a phase transition of the Ising type, at least in the cases investigated. This Ising transition leaves the underlying universal low-temperature O($n$) behavior unaffected.

description: (+)-4-Propyl-9-hydroxynaphthoxazine (+PHNO) is a potent dopamine agonist that has been administered transdermally to four patients with Parkinson's disease and "on-off" fluctuations. Skin patches of increasing size were used to treat these patients, who also received infrequent doses of oral levodopa if required. The effect of +PHNO was measured as an increased duration of action of individual levodopa doses. The clinical effect measured in this way was directly proportional to the plasma concentrations of +PHNO achieved. The plasma concentrations of +PHNO began to rise 4-6 h after patch application and reached a steady state by 24 h. The final plasma concentration of +PHNO was proportional to the area of skin covered.
The life and debt of great American cities : urban reproduction in the time of financialization

description: The Life and Debt of Great American Cities: Urban Reproduction in the Time of Financialization, investigates the relationship between finance and the intensification of racialized patterns of urban development in the US since the turn of the 21st century. I employ mixed methods to explore the spatiality of the municipal bond market, especially regarding its role in the uneven redevelopment of the nation’s aging urban water systems. Moving qualitatively and quantitatively between one site in particular - Jackson, Mississippi - to the political-economies of the 21 largest Black-majority cities in the US, and to the entire country more broadly, I find that redeveloping urban water infrastructures by way of the private municipal bond market collapses new spaces of accumulation into the reproduction of racialized geographies of exclusion. Field research utilizing participant observation and semi-structured expert interviews in Jackson revealed that cities under austerity governance encounter complex financial arrangements in their search for infrastructural funding that they do not retain the capacity to accurately assess or manage, while the analysis of more than 5.3 million municipal bonds over the 44 year period 1970-2014 shows that the largest Black-majority cities have consistently received higher interest rates in the bond market than other cities since the deregulation of the financial industry under the Financial Services Modernization Act of 2000. One of the consequences of the racialization of municipal finance is that the impoverished Black-majority city of Jackson pays more for federally mandated infrastructure upgrades than other cities. The socio-spatial marginalization thus produced creates sites of intense urban vulnerabilities, places lacking both economic and ecological “resilience” in the face of crisis. Austerity, as a method of urban governance and economic recovery, is, I conclude, motivated by the logics of financialization – which is both a mode of accumulation, and significantly, a geography of racialized social reproduction.

description: The use of gadget in the work environment is now a common need. Gadget is one technology product that is very important in supporting work productivity and facilitating communication between employees. This condition causes the gadget charging station to become a very important medium for maintaining connectivity between employees. This study aimed to design gadget charging station using Polycarbonate and HDPE materials. The selection of the two materials was based on the consideration of the characteristics of electrical insulators which were not possessed by metal materials. It was very important to maintain security and safety in its use. The finite element analysis was carried out using Autodesk Inventor Professional 2017 software. The load variations used were 4 kg, 5 kg and 6 kg. The simulation results show that HDPE material with a load variation of 4 kg, 5 kg, and 6 kg had safety factors of 2.65, 2.12, and 1.77, respectively. Safety factors using Polycarbonate materials with variations in the load of 4 kg, 5 kg, and 6 kg respectively were 7.77, 6.22 and 5.18.

description: We calculate spin transport in two-dimensional waveguides in the presence of spatially modulated Zeeman-split energy bands. We show that in a regime where the spin evolution is predominantly adiabatic the spin backscattering rate can be tuned via diabatic Landau-Zener transitions between the spin-split bands [C. Betthausen et. al., Science 337, 324 (2012)]. This mechanism is tolerant against spin-independent scattering processes. Completely spin-polarized systems show full spin backscattering, and thus current switching. In partially spin-polarized systems a spatial sequence of Landau-Zener transition points enhances the resistance modulation via reoccupation of backscattered spin-polarized transport modes. We discuss a possible application as a spin transistor.

description: We translated the Medication Management Ability Assessment (MMAA) from English to Spanish for use via tele-assessment and examined its reliability and validity. Following International Test Commission Guidelines for Translating and Adapting Tests, we used translation/back-translation and a small focus group (n = 6) to adapt a Spanish version of the MMAA. Eighty-six Spanish-speaking adults completed the adapted MMAA via tele-assessment at baseline and at a two-week follow-up visit. Participants also completed several self-report and performance-based cognitive and functional measures. The internal consistency of the MMAA was excellent (standardized Cronbach’s α = 0.90). Performance-based functional assessments (PBFAs) and objective cognition were positively associated with the MMAA at small to medium effect sizes. Self-report measures of daily function and cognition, measures of health literacy, and estimates of premorbid intellectual functioning were not significantly associated with MMAA performance. The test-retest reliability of the MMAA was good (CCC = 0.73, 95% CI [0.62, 0.81]; rs = 0.37, p < 0.001) and demonstrated a small practice effect (Cohen's d = 0.36, p = 0.001). Preliminary evidence for the construct validity of a Spanish-language MMAA administered via tele-assessment further expands the potential clinical utility of PBFAs in culturally diverse, Spanish-speaking populations.

description: Gyrokinetic theory is based on an asymptotic expansion in the small parameter $ε$, defined as the ratio of the gyroradius and the characteristic length of variation of the magnetic field. In this article, this ordering is strictly implemented to compute the electrostatic gyrokinetic phase-space Lagrangian in general magnetic geometry to order $ε^2$. In particular, a new expression for the complete second-order gyrokinetic Hamiltonian is provided, showing that in a rigorous treatment of gyrokinetic theory magnetic geometry and turbulence cannot be dealt with independently. The new phase-space gyrokinetic Lagrangian gives a Vlasov equation accurate to order $ε^2$ and a Poisson equation accurate to order $ε$. The final expressions are explicit and can be implemented into any simulation without further computations.

description: Exposure of drug addicts to MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) has caused a Parkinsonian syndrome accompanied by a selective destruction of dopamine containing neurones in the pars compacta of the substantia nigra. MPTP in the human causes a severe irreversible state that very closely resembles idiopathic Parkinson's disease both in its clinical features and response to pharmacological treatment. Interest in potential environmental agents that might play a role in the aetiology of idiopathic Parkinson's disease is likely to increase as the result of the discovery of the relatively simple molecule MPTP which is highly toxic to the substantia nigra. Until the discovery of the neurotoxicity of MPTP there was no effective animal model of Parkinson's disease. Administration of PTP to monkeys induces persistent parkinsonism which responds to classical antiparkinsonian therapy. The morphological and biochemical changes in the brains of the animals are more limited and selective than those seen in idiopathic Parkinson's disease. The model of MPTP-treated monkeys appears to provide a useful testbed for the evaluation of future treatments for the disease. The precise mechanism of MPTP toxicity has yet to be determined and may provide the clue to the mechanism of neuronal death in Parkinson's disease. After entering the brain MPTP is oxidized to MPP+ (1-methyl-4-phenylpyridine) at an extraneuronal site.(ABSTRACT TRUNCATED AT 250 WORDS)

description: The Color Trails Test (CTT) is a pencil-and-paper (P&P) neuropsychological test. The CTT is divided into two parts that assess sustained visual attention (Trails A) and divided attention (Trails B). The CTT can also be performed in a virtual reality setting (VR-CTT) introducing a wider spatial range of targets. In cases of multiple assessments, repeating the same CTT configuration can bias the results due to fatigue and learning effects. The aim of this study is to create five different short versions of the VR-CTT. The different forms were created by rotating or flipping the original targets spatial layout on one of the axes and by ending it at ball #13. Healthy young participants (N = 15) performed the shortened VR-CTT forms (in a counterbalanced order), the P&P CTT and the original VR-CTT. We found no difference between the completion times of the five forms (p > 0.2), and a significant difference between Trails A and B across all forms (p < 0.04). Additionally, there was no evidence of a learning effect between trials (p > 0.4). Moreover, the shortened VR-CTT forms showed correlations with the P&P CTT (p < 0.05) and with the original VR-CTT (p < 0.06). These findings suggest that all five forms have an equal level of difficulty and that the different forms managed to mitigate the learning effects reported for repeated testing of the same spatial layout. This opens the possibility of applying the shortened VR-CTT forms for research settings and sets the basis for developing it into a clinical diagnostics tool.

description: Objective: Baroreceptor activation has been shown to reduce pain, and the accumulation of such pain reduction has been implicated in the operant learning (under certain circumstances) of hypertension. The current study is an examination of differences in the pain dampening effects of baroreceptor activity in patients with symptomatic and asymptomatic myocardial ischaemia. The objective was to determine whether there are differences between patients with symptomatic and silent myocardial ischaemia with respect to their antinociceptive response to baroreceptor stimulation, and, if so, whether these differences could be related to the absence of angina pectoris pain in patients with silent myocardial ischaemia. Methods: Sensory detection and electrical pain thresholds were compared in nine symptomatic and 10 asymptomatic patients with replicable myocardial ischaemia during PRES (phase related external suction) carotid baroreceptor manipulation in which the pressure inside a neck cuff was phase locked in time to the R wave of the ECG and negative pressure was applied during either systole or diastole. Tourniquet pain thresholds were also determined. Results: It was found that (1) external baroreceptor manipulation had no effect on detection thresholds; (2) painful stimuli were judged by both symptomatic and asymptomatic patients as less intense when delivered during maximum baroreceptor activity, (3) symptomatic and asymptomatic patients did not differ in their sensory detection thresholds; and (4) asymptomatic patients had significantly higher ischaemic (tourniquet) pain thresholds than symptomatic patients. Conclusions: The results indicate that baroreceptor activity can modify the intensity of painful stimuli. The degree to which baroreceptor manipulation affects pain does not appear to differ between patients with painful and silent myocardial ischaemia. Thus the baroreceptor dependent pain inhibition effects seems not to be responsible for the higher ischaemic pain threshold found in the silent myocardial ischaemia group.
Saturation of the tilt aftereffect

description: The tilt aftereffect increases as a logarithmic function of adapting time, reaches saturation after approx 1 hr and decays on a symmetric, logarithmic time-course. This is similar to the time-course of contrast threshold elevation, suggesting that threshold and suprathreshold aftereffects are based on similar type of adaptation processes.

description: To provide understanding of practices and attitudes toward tele-neuropsychology (teleNP) among Veterans Health Administration (VA) psychologists who have joined a related community of practice. Several VA psychologists (the authors) developed this survey to better understand dissemination of teleNP and attitudes toward teleNP among those involved in a VA teleNP community of practice. We contacted VA psychologists within this group to complete the survey. The survey was open from July to August 2021, during which time a total of 62 VA psychologists participated. Response rate was estimated to be 41% of those receiving the survey (62 respondents). Approximately two thirds of those completing the survey reported current practice of teleNP (68%; n = 42). In contrast, only 25% of the entire sample (n = 15) conducted any teleNP pre-pandemic. Job satisfaction related to being able to perform teleNP is high. Support for continued and increased use of teleNP is high, with most respondents (84%) indicating they will be at least somewhat likely to practice teleNP post-pandemic. The survey provides increased support for the use of teleNP by VA psychologists who responded to the survey, with significantly increased adoption since the Covid-19 pandemic, and greater likelihood of intention to use teleNP post pandemic.

description: The influence of the order of bleeding on corticosterone release in the mouse was examined. Female C57/BL6 mice were housed in groups of five animals in a low noise environment. After 10 days, they were successively captured and sacrificed every 2 minutes. The corticosterone levels increased in the fourth and fifth mice in a cage, i.e. within the time intervals from 4 to 6 minutes and from 6 to 8 minutes after the capture of the first animal. These results suggest that quiescent corticosterone levels can be measured only when the blood samples are obtained within 4 minutes following the capture of the first mouse.
