The endocrine and metabolic factors influencing neuroinflammation and recovery following traumatic brain injury
Creators: name: Feeney, Claire
Publisher: name: Imperial College London
Year: 2016

description: Background: Traumatic brain injury (TBI) is a major cause of psychological and cognitive disability in young adults in the developed world. The prognosis for these patients is uncertain. Neuroinflammation may be an important underlying mechanism. Growth hormone deficiency (GHD) is a recognised consequence of TBI and may influence recovery. The metabolic syndrome, a state of insulin resistance, may also influence outcome from TBI. Objectives: i) To study the prevalence and consequences of pituitary dysfunction in soldiers who have suffered a blast TBI (bTBI) ii) To investigate the effect of GH deficiency and serum IGF-I levels on recovery from TBI iii)To evaluate a new positron emission tomography (PET) radioligand [18F]GE-180 purported to measure TSPO neuroinflammation in the healthy human brain iv) To quantify neuroinflammation using [18F]GE-180 in patient following TBI and correlate with metabolic factors. Methods: i) Cross-sectional comparative study of 19 soldiers with bTBI vs. 39 civilians with non-blast TBI. Full endocrine testing, neuropsychological testing, diffusion tensor imaging (DTI) ii) Longitudinal study of 39 patients following TBI; IGF-I and GHD testing at baseline, DTI and neuropsychological testing at two study visits designed to be one year apart. Intervention study of 10 patients with GHD pre- and post- 1 year of GH replacement therapy iii) Cross-sectional PET study using [18F]GE-180 in 10 healthy volunteers iv) Longitudinal [18F]GE-180 PET study in 12 patients following TBI: MRI, PET, neuropsychological and metabolic testing at two visits 6 months apart. Results: i) Higher prevalence of pituitary dysfunction in bTBI (31.6%) compared to nbTBI (2.6%), P =0.004 ii) Greater improvement in fractional anisotropy (FA) in patients with a higher IGF-I at baseline, in the splenium of the corpus callosum (SPCC) and in logical memory scores; no effect of GH replacement per se seen on WM recovery or memory, but significant improvement in QoL and depression scores iii) Low brain uptake of [18F]GE-180 in healthy volunteers, two compartmental 4K-fix (2TC) model provided best fit of the data, no effect of TSPO polymorphism seen iv) no significant effect of genotype seen in TBI patients or in outcome measures between patients and controls. Conclusions i) Novel finding of greater prevalence of pituitary dysfunction in patients with bTBI ii) IGF-I, irrespective of the presence of GHD, improves WM recovery in the SPCC and memory iii) GH replacement does not influence cognition or brain structure in this study but did improve quality of life iv) The TSPO ligand [18F]GE-180 appears to be limited by poor brain uptake v) the 2TC-fix model provides the best model fit iv) distribution volumes are low and there appears to be no effect of the TSPO polymorphism on PET outcome measures in patients with TBI and controls.
On the Destruction and Over-Merging of Dark Halos in Dissipationless N-body Simulations

description: N-body simulations that follow only a collisionless dark matter component have failed to produce galaxy halos or substructure within dense environments. We investigate the `over-merging' problem analytically and with numerical simulations, by calculating dissolution timescales of halos due to physical and artificial dynamical effects. The numerical resolution that has recently been attained is such that mass-loss from two-body relaxation is negligible. We demonstrate that substructure is destroyed in present simulations as a result of large force softening combined with the heating sources of tides and encounters with dissolving substructure. In the limit of infinite numerical resolution, whether or not individual halos or substructure can survive depends sensitively on their inner density profiles. Singular isothermal halos will always survive at some level, however, if halos form with large core radii then the over-merging problem will always exist within dissipationless N-body simulations. In this latter case a dissipational component can increase the halos central density enabling galaxies to survive.

Top-down and bottom-up control of drug-induced sleep and anaesthesia
Creators: name: Uygun, David
Publisher: name: Imperial College London
Year: 2015

description: In recent decades, research has unravelled fascinating detail about the molecular mechanisms underpinning pharmacologic loss of consciousness (LOC). However, the systems-level mechanisms are far less clear. Recent genetic approaches, however, enable unprecedented dissection on neural pathways, and they are paving a way for this line of research. The focus of this thesis is to investigate the neuroanatomical substrates of commonly used drugs which reversibly render us unconscious. Zolpidem is a positive allosteric modulator (PAM) of the GABAA receptor which binds to the benzodiazepine (BZ) site. Because zolpidem binds 1-3,,2 containing GABAA receptors, which are widespread, it acts virtually everywhere. We do not know if zolpidem causes sleep by enhancing GABAergic inhibition throughout the entire brain, or if the therapeutic sleep-inducing property depends upon specific brain circuitry. 2I77 mice are devoid of zolpidem-sensitivity. But, zolpidem-sensitivity can be restored selectively in brain regions, enabling dissection of the circuitry involved in zolpidem’s effect. To isolate the therapeutic effect of zolpidem we deleted GABAA-2I77-subunits and replaced them with GABAA-2F77-subunits in HDC neurons or frontal-cortex in isolation. We were able to selectively restore zolpidem-sensitivity in target neurons. This conferred zolpidem-enhanced IPSCs locally. Compared with wild-type mice and zolpidem-insensitive 2I77lox mice, we found that GABAA-2F77 receptors in either HDC-neurons or frontal cortex alone were enough to rescue the majority of zolpidem-mediated sleep. The response in HDC-2F77 mice was similar to that of an H1-receptor antagonist. By producing a null effect in a negative-control area – the superior colliculus – we show that HDC neurons and the frontal cortex are both substrates involved in zolpidem-mediated sleep. We also investigated the role of synaptic-inhibition onto corticothalamic-neurons in anaesthetic-induced LOC and sleep-wake. To do this, we genetically ablated 2-subunits from layer-6 corticothalamic-cells by crossing Ntsr1-Cre mice with GABAA-2I77lox mice. We found this reduced isoflurane sensitivity, but left sleep-wake behaviours virtually unaffected.

Room temperature vacuum processing of zinc acetate and oxide films
Creators: name: Kim, Yong Ryun
Publisher: name: Imperial College London
Year: 2016

description: The development of organic optoelectronics has progressed rapidly. These devices are now an essential part of our lives (e.g. mobile phone, computer, energy applications and touch-enabled applications). With increasing demand for mass production of low-cost materials, researchers are readily seeking new innovative materials to replace conventional materials based on polymers or small molecules. Metal oxides are one of the most interesting classes of materials, but their current processing is incompatible with organic systems and their application in this field requires new simplified methods of deposition. In this thesis, zinc acetate dihydrate (ZnAc2H2O) has been selected as a precursor for the formation of ZnO. It is inexpensive, has high volatility and demonstrates the oligomerisation of basic zinc acetate (BZA) in vacuum, which is known as a molecular model of ZnO. While there are limited reports of BZA films and powder in the literature, this is the first time that it is fully characterised. The BZA film is prepared on room temperature substrates, with and without pre-coating of 3,4,9,10-perylenetetracharboxylic dianhydride (PTCDA) using organic molecular beam deposition (OMBD), which convey high quality films with well-controlled film thickness and high purity. Contrasting the morphology of the two films, the growth mode for the former is known as “Frank-van-der-Merwe” whereas the latter is “Stranski-Krastanov”. This formation is critical since film orientation and morphology can dramatically alter device performance. A new method for processing metal oxide using small molecules at room temperature has been developed. This method depends on exposing small molecule film to vacuum ultraviolet (VUV) light, generating a photon energy of 7.2 eV (172 nm) via several degradation mechanisms. The effect of atmosphere and irradiation length are evaluated by altering the partial pressure of oxygen and adjusting the height of the sample stage during the VUV process, respectively. The presence of oxygen molecules inducing oxygen radicals and ozone plays a major role in the degradation reaction. This is significantly greater than the effect of irradiance. Finally, a new, room temperature method, VUV process, is used on two BZA films to explore whether this is suitable to the formation of ZnO. Both films exposed to VUV light under different atmospheric conditions show the formation of M-O-M species, with optimised results for high vacuum conditions. Varying the irradiation length results in further enhancement of M-O-M. Furthermore, the underlying PTCDA is preserved during UV exposure. This suggests that ZnO formation acts as an effective barrier layer protecting the underlying organic components.
The iKnife: real time Intra-operative tissue diagnostics using rapid evaporative ionisation mass spectrometry
Creators: name: Muirhead, Laura Jane
Publisher: name: Imperial College London
Year: 2015

description: Background: This thesis describes the development of a novel technique for intra-operative tissue diagnostics, which aims to provide the operating surgeon with molecular diagnostic information in vivo and in near real time by the application of mass spectrometry analysis to tissue specific ions contained within the metabolite rich electrosurgery smoke plume. The system is known as Rapid Evaporative Ionisation Mass Spectrometry (REIMS) or the ‘iKnife’ and it utilises recent developments in systems biology and spectroscopic technology to provide accurate, real time metabolic information in the clinical and operating theatre environment. In addition to tissue diagnostics, REIMS is a potential tool for investigation of the biological processes underpinning the detected lipid changes, contributing to a greater understanding of tumour biology and lipid profiling and identification of novel prognostic or therapeutic targets. Methodology: This body of work developed the instrumentation and tested and validated the analytical methodology for REIMS. Prospective observational studies of breast (N= 45) and colorectal cancer (N=40) were performed at Imperial College NHS trust, for the identification of histologically discrete specific lipidomic profiles. Finally, an endoscopic application was created for the translational application of this technology in the diagnosis and treatment of colorectal cancer. Results: Optimal machine set up was obtained using a Waters Xevo G2-S QTof i-Knife mass spectrometer with a modified atmospheric interface. Multivariate analysis lead to the identification of colorectal adenocarcinoma and invasive breast cancer models through the quantitative analysis of lipid profiles. Significant lipid species responsible for the distinction of healthy tissue and cancer were identified and, based on these profiles, colorectal and breast cancer were identified with a diagnostic accuracy of 93.6% and 88.5% respectively. In addition, tumour characteristics including grade, stage, presence of genetic mutations and hormone receptor status influenced spectral profiles and allowed further discrimination of tumour samples. An endoscopic tool for near real time analysis of colorectal tissue accurately identified the anatomical layers of the colonic wall and discriminated colorectal adenocarcinoma from normal mucosa, ex vivo, with a diagnostic accuracy of 88% and 89.5% respectively. This work lead to the development of fully functioning iKnife and iendoscope instrumental platforms Conclusions: The REIMS platform developed in this thesis is a fundamental first step in facilitating future in vivo REIMS experimentation to determine its potential value as a clinical tool. This analysis has optimized, standardized and validated a methodology for breast and colorectal tissue sampling, and it has identified candidate lipid biomarkers of translational use.

description: Using semi-analytic models of galaxy formation, we investigate the properties of $z\sim3$ galaxies and compare them with the observed population of Lyman-break galaxies (LBGs). In addition to the usual quiescent mode of star formation, we introduce a physical model for starbursts triggered by galaxy-galaxy interactions. We find that with the merger rate that arises naturally in the CDM-based merging hierarchy, a significant fraction of bright galaxies identified at high redshift ($z \ga 2$) are likely to be low-mass, bursting satellite galaxies. The abundance of LBGs as a function of redshift and the luminosity function of LBGs both appear to be in better agreement with the data when the starburst mode is included, especially when effects of dust extinction are considered. The objects that we identify as LBGs have observable properties including low velocity dispersions that are in good agreement with the available data. In this ``Bursting Satellite'' scenario, quiescent star formation at $z\ga2$ is relatively inefficient and most of the observed LBGs are starbursts triggered by satellite mergers within massive halos. In high-resolution N-body simulations, we find that the most massive dark matter halos cluster at redshift $z\sim 3$ much as the LBGs are observed to do. This is true for both the $Ω=1$ CHDM model and low-$Ω$ \LCDM and OCDM models, all of which have fluctuation power spectra $P(k)$ consistent with the distribution of low-redshift galaxies. The Bursting Satellite scenario can resolve the apparent paradox of LBGs that cluster like massive dark matter halos but have narrow linewidths and small stellar masses.

description: A sufficiently magnetized Local Supercluster can explain the spectrum and angular distribution of ultra-high energy cosmic rays. We show that the spectrum of extragalactic cosmic rays with energies below $\sim 10^{20}$ eV may be due to the diffusive propagation in the Local Supercluster with fields of $\sim 10^{-8} - 10^{-7}$ Gauss. Above $\sim 10^{20}$ eV, cosmic rays propagate in an almost rectilinear way which is evidenced by the change in shape of the spectrum at the highest energies. The fit to the spectrum requires that at least one source be located relatively nearby at $\sim 10-15$ Mpc away from the Milky Way. We discuss the origin of magnetic fields in the Local Supercluster and the observable predictions of this model.

Anxiety, stress and risk perception in mothers of food allergic children
Creators: name: Umasunthar, Thisanayagam
Publisher: name: Imperial College London
Year: 2017

description: Background: Food allergy is a common chronic condition, affecting up to 10% of infants. Food allergy can occasionally cause anaphylaxis which is sometimes fatal. The risks of fatal or non-fatal anaphylactic reactions in childhood food allergy have not been quantified previously. Anxiety in the mothers of children with food allergy is increased, and it is unclear whether this is associated with misperception of risk of fatal and non-fatal anaphylaxis. Methods: I undertook a systematic review of published data to quantify the risk of fatal and non-fatal anaphylactic reactions to food, in children and adults with food allergy. Secondly a cross sectional survey of mothers of children attending an inner city hospital was carried out, to assess anxiety in the mothers and children, recruited from three groups: those with food allergy, asthma and hospital attendees without chronic illness. Results: The risk of fatal food anaphylaxis was low at one every 100 000 person years for food allergic adults and children. The risk of non-fatal anaphylaxis was higher and varied between 1 every 10 person years for self-reported anaphylaxis and 1 episode every 1000 person years reactions that required hospital admissions. In the cross-sectional survey we assessed 40, 18 and 38 mothers of food allergic, asthmatic, and no chronic illness (controls) children respectively. Mothers of food allergic children showed increased state anxiety and stress than controls. In regression analysis previous anaphylaxis (p=0.008) and poorly controlled asthma (p=0.004) as well as maternal social class were associated with increased maternal anxiety. Child anxiety and adjustment did not differ between food allergic and control groups. Mothers of food allergic children estimated the risk of fatal food anaphylaxis as greater than reality but estimated risk of death from any cause as less than reality. There was no correlation between risk estimation for fatal food anaphylaxis and measures of maternal anxiety/stress Conclusion: The risk of fatal food anaphylactic reactions for food allergic people is very low. In this study mothers of children with food allergy over-estimated this risk and displayed significantly increased anxiety and stress compared with mothers of children with no chronic illness, but risk estimation was not associated with anxiety. The theoretical and clinical implications are discussed.

description: A mysterious incoherent metallic (IM) normal state with $T$-linear resistivity is ubiquitous among strongly correlated superconductors. Recent progress with microscopic models exhibiting IM transport has presented the opportunity for us to study new models that exhibit direct transitions into a superconducting state out of IM states within the framework of connected Sachdev-Ye-Kitaev (SYK) "quantum dots". Here local SYK interactions within a dot produce IM transport in the normal state, while local attractive interactions drive superconductivity. Through explicit calculations, we find two features of superconductivity arising from an IM normal state: First, despite the absence of quasiparticles in the normal state, the superconducting state still exhibits coherent superfluid transport. Second, the non-quasiparticle nature of the IM Green's functions produces a large enhancement in the ratio of the zero-temperature superconducting gap $Δ$ and transition temperature $T_{sc}$, $2Δ/T_{sc}$, with respect to its BCS value of $3.53$.

description: A detailed simulation of vertical showers in atmosphere produced by primary gammas and protons, in the energy range 1-100 TeV, has been performed by means of the FLUKA Monte Carlo code, with the aim of studying the time structure of the shower front at different detector heights. It turns out that the time delay distribution can be fitted using few parameters coincident with the distribution central moments. Such parameters exhibit a smooth behaviour as a function of energy. These results can be used both for detector design and for the interpretation of the existing measurements. Differences in the time structure between gamma and proton induced showers are found and explained in terms of the non-relativistic component of extensive air showers.

description: Quantum effect is expected to dictate the behaviour of physical systems at low temperature. For quantum magnets with geometrical frustration, quantum fluctuation usually lifts the macroscopic classical degeneracy, and exotic quantum states emerge. However, how different types of quantum processes entangle wave functions in a constrained Hilbert space is not well understood. Here, we study the topological entanglement entropy (TEE) and the thermal entropy of a quantum ice model on a geometrically frustrated kagome lattice. We find that the system does not show a $Z_2$ topological order down to extremely low temperature, yet continues to behave like a classical kagome ice with finite residual entropy. Our theoretical analysis indicates an intricate competition of off-diagonal and diagonal quantum processes leading to the quasi-degeneracy of states and effectively, the classical degeneracy is restored.

description: We consider the production of $^3$He and $^2$H by $^4$He photodisintegration initiated by non-thermal energy releases during early cosmic epochs. We find that this process cannot be the predominant source of primordial $^2$H since it would result in anomalously high $^3$He/D ratios in conflict with standard chemical evolution assumptions. We apply this fact to constrain topological defect models of highest energy cosmic ray (HECR) production. Such models have been proposed as possible sources of ultrahigh energy particles and gamma-rays with energies above $10^{20}$eV. The constraints on these models derived from $^4$He-photodisintegration are compared to corresponding limits from spectral distortions of the cosmic microwave background radiation (CMBR) and from the observed diffuse gamma-ray background. It is shown that for reasonable primary particle injection spectra superconducting cosmic strings, unlike ordinary strings or annihilating monopoles, cannot produce the HECR flux at the present epoch without violating at least the $^4$He-photodisintegration bound. The constraint from the diffuse gamma-ray background rules out the dominant production of HECR by the decay of Grand Unification particles in models with cosmological evolution assuming standard fragmentation functions. Constraints on massive black hole induced photodisintegration are also discussed.

description: The Cryogenic Underground Observatory for Rare Events (CUORE) is a bolometric experiment for neutrinoless double-beta decay in $^{130}$Te search, currently taking data at the underground facility of Laboratori Nazionali del Gran Sasso (LNGS). The CUORE cryostat successfully cooled down a mass of about 1 ton at $\sim$7\,mK, delivering an uniform and constant base temperature. This result marks a fundamental milestone in low temperature detectors techniques, opening the path for future ton-scale bolometric experiments searching for rare events. In this paper we present the CUORE cryogenic infrastructure, briefly describing its critical subsystems.

N-body Simulations of the Small Magellanic Cloud and the Magellanic Stream

description: An extensive set of N-body simulations has been carried out on the gravitational interaction of the Small Magellanic Cloud (SMC) with the Galaxy and the Large Magellanic Cloud (LMC). The SMC is assumed to have been a barred galaxy with a disc-to-halo mass ratio of unity before interaction and modelled by a large number of self-gravitating particles, whereas the Galaxy and LMC have been represented by rigid spherical potentials. The best model we have found succeeded in reproducing the Magellanic Stream (MS), as well as a leading counterpart to the Magellanic Stream (the leading arm), on the opposite side of the Magellanic Clouds to the Stream, which mimicks the overall distribution of several neutral hydrogen clumps observed in the corresponding region of the sky. The elongation of the SMC bar along the line-of-sight direction suggested by Cepheid observations has been partially reproduced, alongside its projected appearance on the sky. The model successfully explains some major trends in the kinematics of young populations in the SMC bar and older populations in the `halo' of the SMC, as well as the overall velocity pattern for the gas, young stars, and carbon stars in the inter-Cloud region.

Mid-infrared Imaging of a Circumstellar Disk Around HR 4796: Mapping the Debris of Planetary Formation

description: We report the discovery of a circumstellar disk around the young A0 star, HR 4796, in thermal infrared imaging carried out at the W.M. Keck Observatory. By fitting a model of the emission from a flat dusty disk to an image at lambda=20.8 microns, we derive a disk inclination, i = 72 +6/-9 deg from face on, with the long axis of emission at PA 28 +/-6 deg. The intensity of emission does not decrease with radius as expected for circumstellar disks but increases outward from the star, peaking near both ends of the elongated structure. We simulate this appearance by varying the inner radius in our model and find an inner hole in the disk with radius R_in = 55+/-15 AU. This value corresponds to the radial distance of our own Kuiper belt and may suggest a source of dust in the collision of cometesimals. By contrast with the appearance at 20.8 microns, excess emission at lambda = 12.5 microns is faint and concentrated at the stellar position. Similar emission is also detected at 20.8 microns in residual subtraction of the best-fit model from the image. The intensity and ratio of flux densities at the two wavelengths could be accounted for by a tenuous dust component that is confined within a few AU of the star with mean temperature of a few hundred degrees K, similar to that of zodiacal dust in our own solar system. The morphology of dust emission from HR 4796 (age 10 Myr) suggests that its disk is in a transitional planet-forming stage, between that of massive gaseous proto-stellar disks and more tenuous debris disks such as the one detected around Vega.

description: The high-multiplicity events of pPb collisions at $\sqrt s_{NN}$ = 5.02 TeV at the LHC exhibit unforeseen collective behaviour. One of the possible explanations to the collectivity could be the formation of thermalized partonic matter, like the one formed in relativistic nucleus-nucleus collisions and is described by the hydrodynamic models. This article presents a study on the centrality dependent long-range 2 < $|Δη|$ < 4 two-particle azimuthal correlations of D-mesons and charged particles in pPb collisions at $\sqrt s_{NN}$ = 5.02 TeV. The study has been conducted on the events, generated with the EPOS3 hydrodynamic code that reproduces most of the features of the pPb data at the LHC energy. There appears a ridge-like structure in the long-range two-particle angular correlations of D-mesons, in the intermediate pT -range, and charged particles in the simulated high-multiplicity pPb events.

description: Otomandibular Auricular syndrome or Hemifacial Microsomia (HFM) is an asymmetric craniofacial malformation which results in hypoplasia of the components of the first and second branchial arches. HFM is the second most common congenital craniofacial anomaly after cleft lip/palate. The incidence of this disorder is 1:3000 26,000, which is usually seen at birth. Males are more commonly affected than females and right side is more affected than the left side. For the pre-surgical evaluation of this anomaly, diagnostic imaging and classification of the facial structures, based on OMENS classification, is of prime importance. The management of this developmental malformation is multidisciplinary. Here we report a case of Hemifacial Microsomia in a six-year-old female kid.
Tissue engineering of the kidney using a whole organ decellularisation approach
Creators: name: He, Ming
Publisher: name: Imperial College London

description: End stage renal failure is associated with major morbidity and mortality, and renal transplantation is the optimal form of renal replacement therapy. However, since the number of organs available for transplantation is limited, an additional (e.g. bioengineered) source of organs for transplantation is both attractive and necessary. Tissue engineering is an interdisciplinary field that applies the principles of engineering and life sciences towards the development of functional replacement tissues for clinical use. Within this field, the technique of whole organ decellularisation allows the preservation of the native vasculature and the complete 3-dimensional macro- and micro-architecture of the organ extracellular matrix (ECM) to create a whole organ ECM bioscaffold. This approach has been employed in the animal model to create viable and partially functional solid organ constructs, some of which have been implanted in vivo, including in the kidney. However, a number of major technical factors and challenges exist before clinical application can be considered, such as the pre-optimisation and standardisation of both decellularisation and recellularisation protocols. The current applications and methods in using xenogeneic whole organ ECM scaffolds to create potentially functional bio-artificial organ constructs for surgical implantation have been reviewed here; comparison of specific trends reveals the need for systematic rationalisation throughout the field. On this basis and using the rat model, the first aim of this project was to optimise the decellularisation process for whole kidney ECM bioscaffolds with regards to two fundamental parameters: concentration of decellularising agent and duration of perfusion, using the most common single decellularising agent drawn from the literature i.e. sodium dodecyl sulphate. Optimisation was determined with regards to structural and functional characteristics of the ECM bio-scaffold as assessed by histology, immunohistochemistry, quantitative assays of DNA and sulfated glycosaminoglycan content, and growth factor quantification. Secondly, recellularisation of the whole kidney bioscaffolds produced using this more optimised protocol was carried out to yield a viable and implantable organ graft/construct, with both primary renal cells and also adult-derived mesenchymal stem cells. Thirdly, both the decellularised and recellularised kidney constructs were implanted in vivo using the renal transplant model in order to investigate the long-term viability and function of the graft construct. This showed long-term viability and biocompatibility of the acellular (decellularised) kidney scaffold when implanted in vivo, but poor viability of all scaffolds (acellular or recellularised) when implanted in combination with vascular perfusion due to a postulated pro-thrombotic mechanism.

description: We report the results of our final search for hot white dwarfs in unresolved, Sirius-type, binary systems with IUE. One new system, RE J0500-364 (DA+F6/7V), has been identified. This star appears to lie at a distance of between 500-1000pc, making it one of the most distant white dwarfs, if not the most distant, to be detected in the EUV surveys. The very low line-of-sight neutral hydrogen volume density to this object could place a lower limit on the length of the Beta CMa interstellar tunnel of diffuse gas, which stretches away from the Local Bubble in a similar direction to RE J0500-364.
