Résumé :

Objective: To compare LJ media and LJ media with penicillin for the growth of Mycobacterium tuberculosis and contamination, in pulmonary tuberculosis (PTB) suspected patients. Methods: A total of 300 PTB suspected cases at National Tuberculosis center (NTC) for analyzed for culture and contamination. Early morning sputum samples were collected in sterile leak-proof falcon tube. Digestion, decontamination and homogenization of sputum were done using NALC-NaOH (Modified Petroff method). The sputum sample was processed on LJ media and penicillin added LJ media and incubated at 37. Cultures were examined after 8 weeks. Results: All the PTB suspected cases were compared in LJ media and LJ media with penicillin, 29.7% (89) were positive, 21% (63) were contaminated on LJ media whereas 41% (123) were positive, 3.7 % (11) were contaminated on penicillin added LJ media. Also, 25 (8%) were 1+ grading, 14 (4.7%) were 2+ grading, whereas 81 (27%) and 45 (15%) were 3+ grading LJ + Penicillin and LJ media respectively. Conclusion: Contamination was reduced by 17.3% with the addition of penicillin to LJ media. And isolation of total positive cultures was enhanced by 11.3%.

Résumé :

Evidence exists implying multiple blood pressure quantitative trait loci (QTL) on rat chromosome 2. To examine this possibility, four congenic strains and nine substrains were developed with varying size chromosome segments introgressed from the spontaneously hypertensive rat (SHR/lj) and normotensive Wistar-Kyoto rat (WKY/lj) onto the reciprocal genetic background. Cardiovascular phenotyping was conducted with telemetry over extended periods during standard salt (0.7%) and high-salt (8%) diets. Our results are consistent with at least three independent pressor QTL: transfer of SHR/lj alleles to WKY/lj reveals pressor QTL within D2Rat21-D2Rat27 and D2Mgh10-D2Rat62, whereas transfer of WKY/lj D2Rat161-D2Mit8 to SHR/lj reveals a depressor locus. Our results also suggest a depressor QTL in SHR/lj located within D2Rat161-D2Mgh10. Introgressed WKY/lj segments also reveal a heart rate QTL within D2Rat40-D2Rat50 which abolished salt-induced bradycardia, dependent upon adjoining SHR/lj alleles. This study confirms the presence of multiple blood pressure QTL on chromosome 2. Taken together with our other studies, we conclude that rat chromosome 2 is rich in alleles for cardiovascular and behavioral traits and for coordinated coupling between behavior and cardiovascular responses.

Résumé :

Purpose. The aim of the study was to test a newly developed prototype for corneal sensitivity measurement (liquid jet (LJ) with saline as stimulus) for repeatability and correlation with the Cochet-Bonnet esthesiometer (CB). This is an excerpt of a master thesis, which was part of a larger study Material and Methods. Corneal sensitivity thresholds (CST) were determined for 30 subjects, in a clinical trial with 30 subjects, with each device on two separate dates (with inter- vals of at least one day and a maximum of fourteen days). In addition, the pain sensitivity questionnaire (PSQ) was applied to determine any possible correlation with corneal sensitivity. Results. Similar standard deviations of the CSTs for LJ and CB were obtained (LJ (M ± SD): 24.3 ± 2.0 dB; CB (M ± SD): 20.0 ± 2.0 dB). No statistically significant difference in CST was found between the two visits for LJ (mean differen- ce: -0.063 dB, p = 0.78), however there was a statistically significant difference for CB (mean difference: -0.641 dB, p = 0.003). LJ CSTs correlated moderately positively with CB CSTs and PSQ (LJ-CB: r = 0.476, p < 0.001; LJ-PSQ: r = 0.437, p < 0.001). Conclusion. LJ offers a significantly larger stimulus bandwidth than CB. Better reproducibility was observed for LJ, while correlation between the results for the two instruments was good. Significant moderate positive correlation was found between LJ CSTs and general pain sensitivity. Keywords esthesiometry, Cochet-Bonnet, Liquid Jet, prototype, PSQ

Résumé :

Lj-RGD3, which contains three Arg–Gly–Asp (RGD) motifs, was first identified from the buccal glands of Lampetra japonica and has been shown to suppress the tumor progression in the previous studies. Apart from the three RGD motifs, Lj-RGD3 is also characterized by its high content of histidine in its amino acid sequence. In order to clarify whether the histidine-rich characterization of Lj-RGD3 is also associated with its anti-tumor activity, mutants were designed in which the three RGD motifs (Lj-112), or all histidines (Lj-27) or both (Lj-26) were deleted. Furthermore, a mutant (Lj-42) in which all histidines and three RGD motifs were respectively substituted with alanines and three Ala–Gly–Asp (AGD) motifs, as well as a mutant (Lj-41) in which all histidines were substituted with alanines was synthesized to avoid alterations in structure which might further cause changes in the peptides’ functions. After recombination and purification, recombinant Lj-112 (rLj-112), recombinant Lj-27 (rLj-27), recombinant Lj-41 (rLj-41), and recombinant Lj-RGD3 (rLj-RGD3) exhibited anti-proliferative activity in B16 cells, respectively; while recombinant Lj-26 (rLj-26) and recombinant Lj-42 (rLj-42) did not affect the proliferation of B16 cells significantly. In addition, the anti-proliferative activity of rLj-112 in B16 cells was due to apoptosis. Typical apoptosis features were observed, including chromatin condensation, fragmented DNA, and increased levels of cleaved caspase 3/caspase 7/nuclear enzyme poly (ADP-ribose) polymerase (PARP) in B16 cells. Similar to rLj-RGD3, rLj-112 was also capable of suppressing the migration and invasion of B16 cells by disturbing the F-actin arrangement. After labeling with FITC, rLj-112 was found localized in the cytoplasm of B16 cells, which induced the internalization of epidermal growth factor receptor (EGFR), suggesting that rLj-112 might block the EGFR mediated signaling pathway. Actually, the phosphorylation level of EGFR and its downstream signal molecules including Akt, PI3K, p38, and ERK1/2 was reduced in the rLj-112 treated B16 cells. In vivo, rLj-112 also inhibited the growth, weight, and volume of the tumors in B16 xenografted C57BL/6 mice without reducing their body weight, indicating that rLj-112 might be safe and might be used as an effective anti-tumor drug in the near future.

Résumé :

The normotensive Wistar-Kyoto (WKY) rat strain is a traditional control for the spontaneously hypertensive rat (SHR). We found trait differences between two inbred normotensive WKY strains, derived originally from different vendors, and compared these two strains from La Jolla-Taconic Farms (WKY/lj-tf) and La Jolla-Charles River (WKY/lj-cr) with the inbred SHR/lj-cr for cardiovascular, diurnal, and activity traits under normal and high (8%) NaCl diets. Marked genetic diversity was found between the two vendor-derived WKY. By using an extended study design and radiotelemetry, we compared WKY/lj-cr, WKY/lj-tf, and SHR/lj-cr with the following results: systolic pressure (120 ± 1, 133 ± 1, 168 ± 3 mmHg, respectively); diurnal variation in heart rate (ΔHR: 46 ± 3, 71 ± 4, 57 ± 2 beats/min, respectively); and salt sensitivity of arterial pressure (Δsystolic: 10 ± 1, 21 ± 1, 20 ± 1 mmHg, respectively). The WKY/lj-tf genotype apparently results in compromised control of arterial pressure and heart rate, especially during high NaCl intake, and greater susceptibility to high pressure (i.e., high NaCl-induced secondary changes). WKY/lj-tf thus constitutes a new inbred borderline hypertensive WKY substrain offering unique opportunities for genomic studies into the development of genetic hypertension.

Résumé :

Ligustici Rhizoma et Radix (LReR) is the dried rhizomes and roots of Ligusticum sinese Oliv. (LS) or Ligusticum jeholense Nakai et Kitag. (LJ). However, in the market, LS and LJ are frequently confused with each other. Since the volatile oils are both the main active components and quality control indicators of LReR, a strategy combining gas chromatography-mass spectrometry (GC-MS) and chemical pattern recognition (CPR) was used to compare the volatile components of LJ and LS. Total ion chromatography (TIC) revealed that phthalides (i.e., neocnidilide) and phenylpropanoids (i.e., myristicin) could be thought of as the most critical components in the volatile oils of LJ and LS, respectively. In addition, the chemical components of the volatile oils in LJ and LS were successfully distinguished by hierarchical cluster analysis (HCA) and principal component analysis (PCA). Moreover, two quality markers, including myristicin and neocnidilide, with a very high discriminative value for the classification of LJ and LS, were found by orthogonal partial least squares discriminant analysis (OPLS-DA). The relative contents of myristicin and neocnidilide were 10.86 ± 6.18% and 26.43 ± 19.63% for LJ, and 47.43 ± 12.66% and 2.87 ± 2.31% for LS. In conclusion, this research has developed an effective approach to discriminating LJ and LS based on volatile oils by combining GC-MS with chemical pattern recognition analysis.

Résumé :

Molecular Dynamics (MD) simulation methods were used to perform simulations of the adsorption of multilayer films of methane and propane onto two structurally different substrates: Lennard Jones wall and Molybdenum. The purpose of the simulations was to determine how differences in substrate type, film thickness, and the interaction between the substrate atoms, affect the structure of film layers at the adsorption surface, as well as to compare how these factors affect the mobility of molecules near the surface as they move along it. The simulations were also performed to see how each of these factors affects the substrate affinity for the adsorbed compound. Analysis suggests a strong influence of these three factors on both the structure and mobility of methane and propane molecules in adsorbed layers.

Résumé :

Since the enactment of the Mineral and Petroleum Resources Development Act 28 of 2002 (MPRDA) a fundamental conflict arose between the rights of a holder of either a prospecting or a mining right, and that of a landowner. On the one hand this can be explained by having regard to the impact the granting of a prospecting or a mining right may have on the rights of the landowner to whose land such a right relates. On the other hand, section 25 of the Constitution of the Republic of South Africa, 1996 (Constitution), provides for the protection of property to a certain extent. The protection that the Constitution affords to a landowner, together with the rights granted to the holder of a prospecting or a mining right by the MPRDA, is the cause of such a fundamental conflict. It is against this background that this study seeks to determine to what extent the MPRDA provides for the protection of a landowner's rights, having regard to the rights granted to the holder of a prospecting or a mining right, which is considered against the protection of property as afforded by the Constitution.

Résumé :

The goal of this work is to develop a model to predict the microstructure of Li-ion batteries, specifically focusing on the cathode component of the batteries. This kind of model has the potential to assist researchers and battery manufacturers who are trying to optimize the capacity, cycle life, and safety of batteries. Two dynamic particle packing (DPP) microstructure models were developed in this work. The first is the DPP1 model, which simulates the final or dried electrode structure by moving spherical particles under periodic boundaries using Newton's laws of motion. The experience derived from developing DPP1 model was beneficial in making the final model, called DPP2. DPP2 is an improved version of DPP1 that includes solvent effects and is used to simulate the slurry-coating, drying, and calendering processes. Two type of properties were used to validate the DPP1 and DPP2 models in this work, although not every property was used with the DPP1 model. First are the structural properties, which include volume fraction, and electronic and ionic conductivities. Experimental structural properties were determined by analyzing 2D cross sectional images of the battery cathodes. These images were taken through focused ion beam (FIB) planarization and scanning electron microscopy (SEM). The second category are the mechanical properties, which include film elasticity and slurry viscosity. These properties were measured through experiments executed by our group. The DPP2 model was divided into two submodels : active-free and active-composite. The 2D cross sectional images of the simulated structure of the models have a similar particle arrangements as the experimental structures. The submodels show reasonable agreement with the experimental values for liquid and solid mass density, shrink ratio, and elasticity. For the viscosity, both models show shear-thinning behavior, which is a characteristic of slurries. The volume fractions of the simulated structures of the active-free and active-composite models have better agreement with the experimental values, which is also reflected in the 2D cross sectional images of the structure.

To describe a material in a more objective manner, one must develop a formalism to express quantitatively the information contained in the images . We conduct a numerical investigation of structural order in the Lennard-Jones 2n-n systems at various density by calculating translational order parameter, orientational order parameter and local orientational order parameter. We identify global structure order by calculating orientational order parameter and translational order parameter. Simulation results are analyzed using an order map representation. We identify local structure order by calculating local orientational order parameter.

In this study, the roots, stems and leaves of KT, KF and LJ were lyophilized and extracted. The extracts of (KT-L, KT-L-W, KT-L-C, KT-L-H, KT-S, KT-S-W, KT-S-B, KT-S-E, KT-S-H and KT-R-C),(KF-L, KF-L-W, KF-L-C, KF-S, KF-S-W, KF-S-Cand KF-R¬-W), and (LJ-B, LJ-C and LJ-H) were investigated its cytotoxicity, antioxidant capacity and whitening effects. The cell viability of the extracts of (KT-L-W, KT-S-W and KT-S-B), (KF-S-W, KF-R-W and KF-L-W), and (LJ-B) were > 90% in human skin fibrolast Hs68 cells for 24 h, using MTS assay. Therefore, none toxicity extracts were continutied for the antioxidant and whitening activities tests in this study. The antioxidant activities of extracts were evaluated with 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and 2,2''-azino-bis[3-ethyl benzthiazoline-6-sulfonic acid] (ABTS) radical scavenging activity, total phenolic content (TPC), total flavonoid content (TFC), reducing power, ferrous ion chelating power, lipid peroxidation using liposome model, cellular reactive oxygen species (ROSs) activities, and the lipid peroxidation assay in tissue by thibarbituric acid reactive substances (TBARS) assay. In brief, the free radical-shaving capacity was evaluated by measuring the scavenging activities of examined the increasing concentrations of extracts on DPPH and ABTS radicals. The EC50 concentrations of radical scavenging activities for KT-S-W, KT-S-B, KT-L-W, KF-S-W, KF-R-W, KF-L-W and LJ-B extracts were 0.9, 1.4, 4.8, 0.9, 0.9, 5.6 and 14.5 ?慊/ml for DPPH, and 215.4, 29.8, 87.4, 26.9, 27.7 and 45.3 ?慊/ml for ABTS, respectively. The EC50 concentrations of DPPH and ABTS radical scavenging activities were 0.9 and 4.8 ?慊/ml for L-ascorbic acid (a positive control). The 100 ?慊/ml concentrations of seven extracts were contained 46.8, 97.4, 53.6, 108.9, 98.7, 78.6 and 74.3 mg/gallic acid g for TPC, and 6.8, 26.9, 12.5, 35.5, 30.6, 22.9 and 55.6 mg/rutin g for TFC. Moreover, the 100 ?慊/ml concentrations of seven extracts included 11.1, 14.3, 12.5, 13.2, 12.2, 14.9 and 16.6 mg/L-ascorbic acid g in reducing power assay. The EC50 concentrations of ferrous ion chelating activities were 3.9, 7.7, 5.8, 6.7, 40.1, 7.6, 2.2 ?慊/ml for seven extracts, and 4.6 ?慊/ml for EDTA (a positive control). Additionally, the inhibition percentages of ROSs activities in H2O2-treated BNLCL2 cell for seven extracts were significantly decreased about 8.1-18.5%. The activities of seven extracts to inhibit lipid peroxidation in mice brain tissue has presented inhibition rate of 59.8-68.9% by TBARS assay. The whitening activities of extracts were investigated with cellular melanin content, tyrosinase and the tyroinase-related proteins in skin whitening mechanisms. After treatment with seven extracts in B16 cells, the antimelanogenesis mechanism were caused by operation of melanocortin-1 receptor (MC1R), microphthalmia-associated transcription factor (MITF) and tyrosinase-related proteins 1 and 2 (TRP-1 and TRP-2) expressions using flow cytometry. These results demonstrated that the KT, KF and LJ extracts have antioxidant and whitening activites, and may offer opportunities for natural antioxidants and whitening skin care products.

Résumé :

Using classical molecular dynamics (MD) simulations, we studied the thermal boundary resistance (TBR)—the inverse of thermal boundary conductance (TBC)—between a single-walled carbon nanotube (SWNT) and surrounding Lennard-Jones (LJ) fluids. With the aim of identifying a general model that explains the TBC for various surrounding materials, the TBC was calculated for three different surrounding LJ fluids, hydrogen, nitrogen, and argon, in a supercritical phase. The results show that the TBC between an SWNT and a surrounding LJ fluid strongly depends on both the local density of the molecules in the first adsorption layer outside SWNT and the intermaterial potential parameters. We also note that the influence of mass on the TBC has a far more significant effect than other intermaterial potential parameters. Furthermore, through our parametric studies we obtained a phenomenological description of the TBC between an SWNT and a surrounding LJ fluid.

Résumé :

Molecular dynamics simulations are used to investigate the subcritical and supercritical evaporation of a Lennard-Jones (LJ) argon nanodroplet in its own vapor. Using a new technique to control both the ambient temperature and pressure, a range of conditions are considered to define a transition line between subcritical and supercritical evaporation. The evaporation is considered to be supercritical if the surface temperature of the droplet reaches the LJ argon critical temperature during its lifetime. Between ambient temperatures of 300 K and 800 K, the transition from subcritical to supercritical evaporation is observed to occur at an ambient pressure 1.4 times greater than the LJ argon critical pressure. For subcritical conditions, the droplet lifetimes obtained from the simulations are compared to independently predicted lifetimes from the D2 law.

Résumé :

This paper presents a new molecular model to define the interactions of a liquid crystalline polymer (LCP) flowing between two serrated walls. The wall is modeled by a rough atomic serrated wall. The roughness characteristics are given by the space and height of the serrated wall. Molecular model of the liquid crystalline polymer is described by an improved model that consists of GB (Gay-Berne) sites as rigid segments and LJ (Lennard-Jones) sites. There are two nonlinear springs each connecting from a GB site to a LJ site that situate between two GB sites as flexible segments. This improved model is newly developed to reduce the computational cost from that of the hybrid GB/LJ model, which has provided an effective way to investigate the boundary problems and flowing behaviors of LCPs at nano-scale. The molecular dynamics (MD) simulation using this reduced computational cost method to study the effect of boundary conditions on alignment and rheological properties of the LCP is shown in the result.

Résumé :

Heterogeneous vapor bubble nucleation was numerically simulated on surfaces containing nanometer-sized rectangular cavities of various sizes (ranging from 2.72–9.36 nm width & 4.09–8.34 nm depth). Non-equilibrium molecular dynamics simulations at constant wall temperature were carried out for the two-dimensional (2D) Lennard-Jones (LJ) fluid which was in thermal contact with LJ solid wall. Nucleation was induced by expanding the system volume to a metastable state while keeping the temperature of the solid wall constant. When the aspect ratio (depth-to-width) of the cavity was large (∼3-to-1), the nucleation rate was increased nearly three-fold compared to the flat surface for relatively large wettability; however, the nucleation rate was nearly the same for lower wettability surfaces. Nucleation was generally favored within the cavities due to the stabilization of the cavity side-walls. The value of cutoff radius, wall temperature, and solid-liquid wettability was varied to determine their effect on nucleation rate. The 2D model was validated by comparing thermodynamic averages of pressure and potential energy to predicted values from a 2D LJ equation of state.

Résumé :

A numerical analysis method for elastic contact mechanics between a sphere and a flat with a sub-nanometer roughness is presented by taking account of Lennard-Jones (LJ) surface forces. In contrast to conventional theories, the elastic deformations and LJ surface forces of both mean surfaces and contacting asperities are taken into account. Convergent solutions obtained by a simple under-relaxation iteration method are discussed for 2-mm radius glass slider and 20-mm radius head slider contacting with a magnetic disk. It is found that the increase in adhesion force with a decrease in surface roughness can be suppressed by deceasing asperity radius and increasing asperity density.

Résumé :

Molecular dynamics (MD) simulations are carried out to calculate the surface tension of bubbles formed in a metastable Lennard-Jones (LJ) fluid. The calculated normal and transverse pressure components are used to compute a surface tension which is compared to the surface tension computed from the Young-Laplace equation. Curvature effects on surface tension are investigated by performing various sized simulations ranging from 6,912 to 256,000 LJ particles. Density profiles, pressures, and calculated surface tension are shown to have a strong dependence on the choice of the interaction cutoff radius. A cutoff radius of 8σ, significantly larger than that commonly used in the literature, is recommended for accurate calculations in liquid-vapor systems.

Résumé :

A non-equilibrium molecular dynamics model is developed to calculate the thermal conductivity of single layer graphene supported on silicon dioxide. We use the Tersoff potential to describe the carbon-carbon interactions within graphene, and a Lennard-Jones (LJ) potential to describe the interactions between graphene and silicon dioxide. To overcome possible artifacts of thermal expansion, the model avoids using any periodic or fixed boundary conditions for the graphene flake. For both smooth and rough substrates, the simulations show that increasing the LJ coupling strength between graphene and substrate can reduce the in-plane thermal conductivity of graphene. We also investigated the effects of roughness. The simulations show that the thermal conductivity is sensitive to the roughness only when the coupling is large. These results indicate how the thermal properties of graphene may be modified by adjusting the coupling and roughness of the substrate.

Résumé :

As a student undertaking a Longitudinal Integrated Clerkship (LIC)1 based in a GP practice in a rural community in the North of Scotland, I have been lucky to be given responsibility and my own clinic lists. Every day I conduct consultations that change my practice: the challenge of clinically applying the theory I have studied, controlling a consultation and efficiently exploring a patient's problems, empathising with and empowering them to play a part in their own care2 – and most difficult I feel – dealing with the vast amount of uncertainty that medicine, and particularly primary care, presents to both clinician and patient. I initially consulted with a lady in her 60s who attended with her husband, complaining of severe lower back pain who was very difficult to assess due to her pain level. Her husband was understandably concerned about the degree of pain she was in. After assessment and discussion with one of the GPs, we agreed some pain relief and a physio assessment in the next few days would be a practical plan. The patient had one red flag, some leg weakness and numbness, which was her ‘normal’ on account of her multiple sclerosis. At the physio assessment a few days later, the physio felt things were worse and some urgent bloods were ordered, unfortunately finding raised cancer and inflammatory markers. A CT scan of the lung found widespread cancer, a later CT of the head after some developing some acute confusion found brain metastases, and a week and a half after presenting to me, the patient sadly died in hospital. While that was all impactful enough on me, it was the follow-up appointment with the husband who attended on the last triage slot of the evening two weeks later that I found completely altered my understanding of grief and the mourning of a loved one. The husband had asked to speak to a Andrew MacFarlane Year 3 ScotGEM Medical Student 2 doctor just to talk about what had happened to his wife. The GP decided that it would be better if he came into the practice - strictly he probably should have been consulted with over the phone due to coronavirus restrictions - but he was asked what he would prefer and he opted to come in. I sat in on the consultation, I had been helping with any examinations the triage doctor needed and I recognised that this was the husband of the lady I had seen a few weeks earlier. He came in and sat down, head lowered, hands fiddling with the zip on his jacket, trying to find what to say. The GP sat, turned so that they were opposite each other with no desk between them - I was seated off to the side, an onlooker, but acknowledged by the patient with a kind nod when he entered the room. The GP asked gently, “How are you doing?” and roughly 30 seconds passed (a long time in a conversation) before the patient spoke. “I just really miss her…” he whispered with great effort, “I don’t understand how this all happened.” Over the next 45 minutes, he spoke about his wife, how much pain she had been in, the rapid deterioration he witnessed, the cancer being found, and cruelly how she had passed away after he had gone home to get some rest after being by her bedside all day in the hospital. He talked about how they had met, how much he missed her, how empty the house felt without her, and asking himself and us how he was meant to move forward with his life. He had a lot of questions for us, and for himself. Had we missed anything – had he missed anything? The GP really just listened for almost the whole consultation, speaking to him gently, reassuring him that this wasn’t his or anyone’s fault. She stated that this was an awful time for him and that what he was feeling was entirely normal and something we will all universally go through. She emphasised that while it wasn’t helpful at the moment, that things would get better over time.3 He was really glad I was there – having shared a consultation with his wife and I – he thanked me emphatically even though I felt like I hadn’t really helped at all. After some tears, frequent moments of silence and a lot of questions, he left having gotten a lot off his chest. “You just have to listen to people, be there for them as they go through things, and answer their questions as best you can” urged my GP as we discussed the case when the patient left. Almost all family caregivers contact their GP with regards to grief and this consultation really made me realise how important an aspect of my practice it will be in the future.4 It has also made me reflect on the emphasis on undergraduate teaching around ‘breaking bad news’ to patients, but nothing taught about when patients are in the process of grieving further down the line.5 The skill Andrew MacFarlane Year 3 ScotGEM Medical Student 3 required to manage a grieving patient is not one limited to general practice. Patients may grieve the loss of function from acute trauma through to chronic illness in all specialties of medicine - in addition to ‘traditional’ grief from loss of family or friends.6 There wasn’t anything ‘medical’ in the consultation, but I came away from it with a real sense of purpose as to why this career is such a privilege. We look after patients so they can spend as much quality time as they are given with their loved ones, and their loved ones are the ones we care for after they are gone. We as doctors are the constant, and we have to meet patients with compassion at their most difficult times – because it is as much a part of the job as the knowledge and the science – and it is the part of us that patients will remember long after they leave our clinic room.
