Exploring the impact of wheelchairs on individuals in residential care : a two-phase, mixed-methods study
Creators: name: Mortenson, William Bennett
Publisher: name: University of British Columbia
Year: 2010

description: Wheelchairs are the primary means of mobility for most of the older adults living in residential care. Despite their intuitive benefits, little research has explored the outcomes of wheelchair use for facility residents. Therefore, a two-phase, mixed-methods project was undertaken. Phase 1: Exploratory Ethnographic Study. Objectives. 1. To explore the perceptions and experiences of facility life among residents who use wheelchairs as their primary means of mobility and to examine how wheelchairs are used in these settings. 2. To identify nondemographic factors that enable or curtail the mobility, participation and life satisfaction of these residents. Method. Sixteen residents from two facilities took part in participant observations, and these residents or surrogate family members completed a series of in-depth interviews. Results. We drew upon the work of Pierre Bourdieu to understand how wheelchairs and other forms of capital could either enable or curtail the things residents did and the places that they went. These findings emphasize the critical role that the facility environment plays in the lives of residents. This study identified a wide range of potential wheelchair-related, environmental, and personal factors related to resident’s mobility, participation, and life satisfaction. Phase 2: Quantitative Cross-sectional Study. Objective. To identify the predictors of mobility, participation and life satisfaction of residents who use wheelchairs as their primary means of mobility. Method. We conducted a cross-sectional study with 268 residents from 11 facilities. To measure independent and dependent study variables we administered standardized personal, wheelchair-related and environmental tools and collected socio-demographic and wheelchair equipment data. Results. Wheelchair skills (including the capacity to engage brakes and manoeuvre) were the most important independent predictors of mobility. Depression was the most important independent predictor of life satisfaction among self-responding and proxy subjects and of participation for self-responding subjects. For proxy subjects, mobility was the most important independent predictor of participation; and depression approached significance. Significance. The study findings emphasize the pivotal role that wheelchairs play in the lives of residents, reveal institutional practices that may curtail their mobility and participation, suggest potential policy and practice changes, and lay the groundwork for future research.

description: Der Beitrag untersucht die Nutzung von Reddit als Medium und digitale Sprachressource im Kontext von DaF/DaZ und stellt verschiedene Ansätze zur Nutzung von Reddit als Korpus vor. Anhand einer Fallstudie, die sprachliche Variationen und Diskurspraktiken in den deutschsprachigen Subreddits r/Austria und r/de vergleicht, werden thematische und sprachliche Unterschiede herausgearbeitet und hinsichtlich ihrer Implikationen für den DaF/DaZ-Unterricht diskutiert. Insgesamt unterstreicht der Beitrag die Bedeutung einer systematischen Analyse und didaktischen Aufbereitung der auf Reddit verfügbaren sprachlichen Ressourcen, um das Verständnis für sprachliche Variation und kulturelle Unterschiede im digitalen Zeitalter zu fördern.

Mechanisms of vascular dysfunction in diabetes and hypertension
Creators: name: Nagareddy, Prabhakara Reddy
Publisher: name: University of British Columbia
Year: 2010

description: Cardiovascular complications of diabetes are related in part to abnormal vascular function, a manifestation of the many changes induced in the arterial wall by the metabolic abnormalities accompanying diabetes and insulin resistance. We investigated the biochemical and functional consequences of diabetes and metabolic abnormalities, particularly insulin resistance, on vascular function, using two different animal models, the streptozotocin (STZ)-diabetic rat model of type 1 diabetes and the high fructose diet-fed rat model of insulin resistance and hypertension (FHR). In STZ diabetic rats, we found that complex biochemical interactions led to changes in hemodynamic variables. Specifically, we found that increased activation of PKCβ2 leads to induction of inducible nitric oxide synthase (iNOS), which results in increased production of both nitric oxide and peroxynitrite, causing pressor hypo-responsiveness, depressed cardiac function, mean arterial blood pressure and heart rate and impaired endothelial function in STZ-diabetic rats. Further, we found that hyperglycemia-induced activation of PKCβ2 is antecedent to increases in oxidative stress, activation of ERK1/2, NF-κB, and iNOS expression, and the protective effects of PKCβ or iNOS inhibition in STZ diabetic rats are associated with inhibition of iNOS-mediated peroxynitrite formation. In contrast to STZ diabetic rats, endothelial dysfunction in FHR is associated with hypertension. In FHR, we investigated the role of matrix metalloproteinases (MMP) and epidermal growth factor receptor (EGFR) transactivation, a novel pathway that has been proposed to link all the pathological features of hypertension including endothelial dysfunction, enhanced vascular tone and hypertrophic growth of cardiovascular tissue. We found that in normal arteries, MMP-EGFR pathway modulates vascular tone, at least in part, via activation of PI3-kinase and mitochondrial ATP synthesis. In FHR arteries, inhibition of MMPs by doxycycline improved endothelial function while EGFR inhibition by AG1478 promoted vasorelaxation. Further, in insulin resistant vascular smooth muscle cells and arteries from FHR, pharmacological or siRNA inhibition of MMP-EGFR signaling normalized the increased expression and activity of contractile proteins (MLCK, MLC II) and their transcriptional activators (P90RSK and SRF) in addition to the prevention of hypertension in FHR. Our data suggests that the MMP-EGFR pathway could be a potential target in the treatment of hypertension.

description: Exchange fluxes across the groundwater–surface-water interface are critical components of hydrologic, climatic, and ecologic processes. We present details of the construction of a low-cost Controlled Flux Tank Calibration System (CFTCS). The construction of this low-cost ($318) easily replicable system allows for comparative testing of different groundwater flow measurement methodologies. This work presents an illustrated step-by-step construction guide and intends to contribute to the development of studies on the groundwater monitoring in coastal lagoons.
Pharmacokinetics and limited sampling strategies of mycophenolic acid in islet transplant recipients
Creators: name: Al-Khatib, Mai
Publisher: name: University of British Columbia
Year: 2009

description: Mycophenolic acid (MPA), the active metabolite of mycophenolate mofetil (MMF) is an immunosuppressant that is used in organ transplantation and exhibits wide inter-patient variability in its pharmacokinetic properties in various transplant populations. However, only one study has addressed the pharmacokinetics of MPA in the islet transplant population. The objectives of our study were to characterize the pharmacokinetics of MPA and its two glucuronidated metabolites as well as develop limited sampling strategies (LSSs) for the estimation of MPA area-under- the curve (AUC) in the islet transplant population. Sixteen stable islet transplant recipients on steady-state MPA therapy were recruited. The patients were also on tacrolimus-based, steroid-free immunosuppressant regimens. Blood samples were collected at 0, 0.33, 0.66, 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post-dose. Concentrations of MPA, free MPA, 7-O-mycophenolic acid glucuronide (MPAG) and acyl-mycophenolic acid glucuronide (AcMPAG) in the plasma samples were measured by a high performance liquid chromatography-ultraviolet detection technique. Conventional pharmacokinetic parameters were determined by non-compartmental analysis. Multiple regression analysis was used to develop the LSSs, using all 16 patients’ profiles. The resulting equations were validated for their bias and precision using the jackknife method. There was large inter-patient variability in all pharmacokinetic parameters of MPA, MPAG and AcMPAG. Reasons for this variability are multifactorial and should be the focus of future multicenter studies. Four 3-concentration and one 2-concentration LSS met predetermined criteria and had conventional sampling times. The LSS that we recommend is the one utilizing two concentrations: AUC=1.547+1.417C1+9.448C4. This equation is convenient and can be useful for clinicians in optimizing patient care.

description: The lightweight designs of automobiles and space shuttles have raised the bar for aluminum (Al) and its alloys. Graphene (GP) has found widespread application in aluminum matrix composites due to its exceptional mechanical, electrical, and thermal properties. In this study, a successful preparation of 6061Al reinforced with GP was achieved through a powder metallurgy method. This involved mixing GP with 6061Al alloy powders via ball milling, followed by hot-pressing sintering to produce the final GP-reinforced Al alloy nanocomposite. The effect of the pH value of the plating solution on the electroless plating of GP has been studied for the first time. The results show that the strength of the aluminum-matrix composites with copper plating has been significantly improved compared with that of the composites without copper plating. When the pH value of the plating solution is 12, the tensile strength of the composites obtained has been increased by 60.41%. Compared with the matrix material, the conductivity of the composite material has also increased. This work shows that the mechanical behavior of graphene-reinforced metal matrix composites (MMCs) can be improved by adjusting the distribution of graphene coatings, which is of great benefit for the preparation of high strength and lightweight composites with good electrical conductivity.

Sulcophanaeus auricollis joffrei Martínez, 1988a: 90 (original description). Type locality: Venezuela: Táchira:“Vía Chorro del Indio and Río Negro”.Name-bearing type: holotype (unknown whereabouts). Originally deposited in Martínez’s personal collection, the holotype would now be expected to be in MACN (see Cupello & Vaz-de-Mello 2018), but it was not located there in 2014 by MC. Edmonds (2000), mistakenly assuming that Martínez’s name-bearing types had been transferred to the CMNC with the rest of his collection, did not search for the holotype in the MACN. However, he found in the CMNC two of the five paratypes originally deposited in Martínez's collection. The other three, including the one originally assigned as the “ allotype ”, are, like the holotype, missing.

description: In the present work, novel and effective quinoline-based polybenzoxazines coatings were prepared on cotton fabrics and mild steels to improve the hydrophobic properties and corrosion resistance, respectively. For this purpose, four quinoline containing mono-oxazine-based benzoxazines were synthesized using 8-hydroxyquinoline (Q), and various monoamines, such as: butylamine (ba), hexylamine (ha), octylamine (oa) and aniline (a). The molecular structure of the benzoxazine monomers was verified by 1H-NMR and FTIR spectroscopy. The effect of the aliphatic and aromatic functional groups of the benzoxazines on oxazine ring-opening curing was investigated, and the influence of their corresponding materials on thermal and morphological properties was also elucidated. These quinoline-based monomers have been successfully coated onto the surface: i) cotton fabrics to be used as a water – oil separation method; and ii) mild steel as inhibitor of the corrosion. In this sense, cotton fabric coatings exhibited highly hydrophobic properties (contact angle from 124° to 139°), and subsequently the water oil-separation efficiency was measured to the material that presented the highest contact angle (Poly Q-oa), obtaining a 91% separation efficiency. For benzoxazines coatings on mild steel, impedance tests have indicated that these polymers are corrosion inhibitor effectives. Finally, the antibacterial properties of the quinoline based benzoxazines was also analysed, indicating good antibacterial resistance owing to the existence of long alkyl chains in their respective molecular structure. According to the results obtained from numerous analyses, the quinolone-based polybenzoxazines can be considered as successful materials for applications such as corrosion resistance, oil-water separation, marine coating and microelectronics insulation.
