Understanding hope from the voices of service users and providers across Canada
Authors: Guerrero Cristina Alexandra , Lackner Tina 
Published: May 2024

Although Canada is home to the second largest non-profit and volunteer sector in the world, there is an absence of an overarching framework to guide human services delivery (Hall et. al., 2005; Rahmani, 2022). This paper documents the first phase of a three-year study that seeks to begin to bridge this gap by learning from both HS providers and users’ narratives, specifically in relation to the topics of hope, self-compassion, and authentic collaboration.
The first phase of the research focused on the topic of hope via the following questions:

How do HS consumers and service providers meaningfully experience hope in the course of HS service delivery within their lifeworlds?
How might these experiences inform a guiding framework for Canadian HS service delivery?

A thematic analysis of surveys and interviews collected from six partner organizations across Canada revealed the following themes: 1) the importance of human connections; 2) the building and evolution of hope; and 3) the futurity of hope. These findings point out several implications for practice and research, including a need for human-centred training that focuses more on topics like sensitivity and compassion. Respondents, particularly the service providers, also spoke to the need for strategies and opportunities to take care of oneself physically, mentally, and spiritually. This call is especially prevalent in the wake of the COVID-19 pandemic and funding cuts across Canada.

Experimental and Theoretical Predictions of Static Plantar Pressure of Socks with Different Stitch Lengths
Authors: Soltanzadeh Zeynab , Najar Saeed Shaikhzadeh , Khazaei Somayeh 
Published: May 2024

Background: Socks are mainly used to give the foot more comfort while wearing shoes. Stitch density of the knitted fabric used in socks can significantly affect the sock properties because it is one of the most important fabric structural factors influencing the mechanical properties. Continuous plantar pressures can cause serious damage, particularly under the metatarsal heads, and it is deduced that using socks redistributes and reduces peak plantar pressures. If peak pressure under the metatarsal heads is predicted, then it will be possible to produce socks with the best mechanical properties to reduce the pressure in these critical areas.
Methods: Plain knitted socks with three different stitch lengths (high, medium, and low) were produced. Static plantar pressure measurements by the Gaitview system were accomplished on ten women and then compared with the barefoot situation. Also, the peak plantar pressure of three types of socks under the metatarsal heads are theoretically predicted using the Hertz contact theory.
Results: Experimental results indicate that all socks redistribute the plantar pressure from high to low plantar pressure regions compared with barefoot. In particular, socks with high stitch length have the best performance. By increasing the stitch length, we can significantly reduce the peak plantar pressure of the socks. Correspondingly, the Hertz contact theory resulted in a trend of mean peak pressure reductions in the forefoot region similar to the socks with different stitch densities.
Conclusions: The theoretical results show that by using the Hertz contact theory, static plantar pressure in the forefoot region can be well predicted at a mean error of approximately 9% compared with the other experimental findings.

Published: May 2024

Background: The present study aimed to analyze and compare the efficacy of the anterolateral and posterolateral approaches for surgical treatment of supination–external rotation type IV ankle fractures.
Methods: This retrospective study enrolled 60 patients (60 feet) with supination–external rotation type IV ankle fractures, including 30 patients (30 feet) treated by means of the anterolateral approach and 30 patients (30 feet) treated by means of the posterolateral approach. Postoperative clinical efficacy was compared between the groups based on operation time, intraoperative blood loss, postoperative complications, fracture healing time, visual analog scale scores, Short Form-36 Health Survey scores, and American Orthopedic Foot and Ankle Society scores. Comparisons between the two groups were performed using independent-samples t tests and analyses of variance. Intragroup differences were compared using paired t tests, and the χ2 test was used to compare categorical variables.
Results: All 60 included patients completed follow-up ranging from 12 to 18 months (mean duration, 14.8 ± 3.5 months). Although baseline characteristics were similar in the two groups, there were significant differences in operation time (86.73 ± 17.44 min versus 111.23 ± 10.05 min; P < .001) and intraoperative blood loss (112.60 ± 25.05 mL versus 149.47 ± 44.30 mL; P < .001). Although fracture healing time (10.90 ± 0.66 weeks versus 11.27 ± 0.94 weeks; P = .087) was shorter in the anterolateral group than in the posterolateral group, the difference was not significant. Postoperative complications occurred in one and three patients in the anterolateral and posterolateral approach groups, respectively. Visual analog scale scores were significantly lower in the anterolateral group than in the posterolateral group (1.43 ± 0.50 versus 1.83 ± 0.75; P = .019), although there was no significant difference in Short Form-36 Health Survey scores between the groups (73.63 ± 4.07 versus 72.70 ± 4.04; P = .377). However, American Orthopedic Foot and Ankle Society scores were higher in the anterolateral group than in the posterolateral group (80.43 ± 4.32 versus 75.43 ± 11.32; P = .030).
Conclusions: Both the anterolateral and posterolateral approaches can achieve good results in the treatment of supination–external rotation type IV ankle fractures. Compared with the posterolateral approach, the anterolateral approach is advantageous for the treatment of supination–external rotation type IV ankle fractures given its safety and ability to reduce trauma, clear field of view revealed, and allow for exploration and repair of the inferior tibiofibular anterior syndesmosis within the same incision.
Electrodynamics in accelerated frames revisited
Authors: Maluf J.W. , Ulhoa S.C. 
Published: August 2010

AbstractMaxwell's equations are formulated in arbitrary moving frames by means of tetrad fields, which are interpreted as reference frames adapted to observers in space‐time. We assume the existence of a general distribution of charges and currents in an inertial frame. Tetrad fields are used to project the electromagnetic fields and sources on accelerated frames. The purpose is to study several configurations of fields and observers that in the literature are understood as paradoxes. For instance, are the two situations, (i) an accelerated charge in an inertial frame, and (ii) a charge at rest in an inertial frame described from the perspective of an accelerated frame, physically equivalent? Is the electromagnetic radiation the same in both frames? Normally in the analysis of these paradoxes the electromagnetic fields are transformed to (uniformly) accelerated frames by means of a coordinate transformation of the Faraday tensor. In the present approach coordinate and frame transformations are disentangled, and the electromagnetic field in the accelerated frame is obtained through a frame (local Lorentz) transformation. Consequently the fields in the inertial and accelerated frames are described in the same coordinate system. This feature allows the investigation of paradoxes such as the one mentioned above.
Understanding the effect of chain entanglement on the glass transition of a hydrophilic polymer
Authors: Lu Xiaolin , Xue Gi , Mi Yongli 
Published: August 2010

AbstractIn this article, we report an interesting phenomenon of the glass transition temperature (Tg) deviation of a hydrophilic polymer. Polyacrylamide (PAL) samples with different extents of chain entanglement were prepared by spray drying and solution casting. We found that the glass transition temperature increases as the extent of chain entanglement decreases upon the sub‐Tg annealing. The water content in the PAL matrix is found with no direct correlation to Tg. However, the observation of a faster diffusion process of water in the disentangled PAL matrix offers an evidence of a faster relaxation process of disentangled PAL molecules. The Tg increase of the disentangled PAL samples is believed to be associated with the increased molecular interaction during the chain relaxation process upon the sub‐Tg annealing. A macroscopic evidence is the fact that the density of the hot‐laminated samples increases as the extent of chain entanglement decreases. A thermodynamic analysis suggests that enthalpy more than entropy favors an elevated Tg of a disentangled hydrophilic polymer upon the sub‐Tg annealing. We believe that this research provides new understanding of Tg of the hydrophilic polymers, which are being extensively used in bio‐related studies. © 2010 Wiley Periodicals, Inc.

An altar in honor of the anatomical gift
Authors: Kooloos Jan G.M. , Bolt Sophie , van der Straaten Joop , Ruiter Dirk J. 
Published: August 2010

AbstractOn All Saints Day 2009 a monument for body donors was unveiled by the Department of Anatomy, at the Radboud University Nijmegen Medical Centre (RUNMC). Although body donation to medical science contributes substantially to the quality of medical education, the ceremony was only the first time that the RUNMC publicly reciprocated the anatomical gift. By means of the monument the department of Anatomy endeavors to express gratitude for the gift of body donors and raise awareness among students to value the gift and treat donor bodies with the proper respect. Furthermore, the large attendance of bereaved at the unveiling ceremony, revealed another equally important meaning of the monument, which is the significance of the monument to the donor kin. The wish of a body donor has large implications for the way bereaved can take leave of the donor; there is limited time to bade the deceased farewell, the body will not be available for a funeral, and the donor kin stay behind empty handed without even a grave or ashes. Therefore the monument can be meaningful by facilitating the bereaved with a place of commemoration. The design of the monument anticipates on these multiple meanings and symbolisms by placing an old marble dissection table in the shape of an altar and fixing a bronze sculpture of a phoenix as symbol of imperishableness.

AbstractBasic and superior reasoning skills are woven into the clinical reasoning process just as they are used to solve any problem. As clinical reasoning is the central competence of medical education, development of these reasoning skills should occur throughout the undergraduate medical curriculum. The authors describe here a method of teaching reasoning skills in a clinical context during a human anatomy course. Anat Sci Educ 3:267–271, 2010. © 2010 American Association of Anatomists.
Contact force estimation and regulation in active pantographs: An algebraic observability approach
Authors: Pisano Alessandro , Usai Elio 
Published: August 2010

AbstractIn this paper we extend our previous work concerning the regulation of the contact force in active train pantographs with wire‐actuators. In particular, we suggest a second‐order sliding mode based control scheme that avoids the direct measurement of the contact force, which is quite unpractical in real applications. The idea is to estimate the contact force using the measured displacements of the upper and lower pantograph frames. Unlike the contact force, the frames displacements can be measured accurately and reliably in practice.The estimation method, based on the algebraic observability theory, entails the use of real‐time sliding‐mode differentiators. It makes use explicitly of the mechanical characteristics of the upper frame only. The considered second‐order sliding mode control scheme also includes proper linear compensating cascade filters devoted to cope with the de‐stabilizing effects of the resonant wire actuator. We show that such a control scheme can be effectively combined with the given contact force estimation method.Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Effects of resveratrol and flavonols on cardiovascular function: Physiological mechanisms
Authors: Yap Suwan , Qin Chengxue , Woodman Owen L. 
Published: August 2010

AbstractResveratrol and flavonols are commonly found together in fruits and vegetables and, therefore, consumed in the diet. These two polyphenols share both vasorelaxant and antioxidant activity and may act together to improve cardiovascular function. This review examines the mechanisms by which resveratrol and flavonols influence cardiovascular function and perhaps offer a new approach for the development of therapeutic agents for the prevention and/or treatment of coronary artery disease. © 2010 International Union of Biochemistry and Molecular Biology, Inc.
Influence of a low dose of dietary soybean on bone properties and mineral status in young rats
Authors: Piastowska‐Ciesielska Agnieszka Wanda , Gralak Mikolaj Antoni 
Published: August 2010

AbstractThe aim of this study was to evaluate effects of dietary supplemenation with genistein, daidzein stachyose, and raw or cooked soybean on mineral content, optical density, and mechanical properties of bones in growing rats. The experiment was performed on 70 male young Wistar rats (4 weeks old at the start of the experiment) divided into seven groups. Genistein, daidzein, or stachyose were administered by gavage. Raw or cooked soybean was added directly to the diet (1%) The experiment lasted 28 days. Femurs were removed postmortem and kept until analysis at −20°C. Mineral content in bones was determined by atomic absorption flame spectrometry, and inductively coupled plasma atomic emission spectrometry. Optical density was analyzed with a KODAK 1D 3.5 system. Mechanical properties were tested using INSTRON 4301 equipment. Genistein increased mineral content in bones of growing rats. Biological action of genistein and daidzein on the mineralization of bone tissues in growing rats was different. Addition of stachyose (1.9 mg/day/rat) did not affect bone tissues, nor did the addition of raw or cooked soybean. None of the studied biologically active substances: genistein (0.26 mg/day/rat), daidzein (0.104 mg/day/rat), stachyose (1.9 mg/day/rat), or soybean had an effect on bone optical density.
Phytochemicals and adipogenesis
Authors: Andersen Charlotte , Rayalam Srujana , Della‐Fera Mary Anne , Baile Clifton A. 
Published: August 2010

AbstractObesity is an increasing health problem all over the world. Phytochemicals are potential agents to inhibit differentiation of preadipocytes, stimulate lipolysis, and induce apoptosis of existing adipocytes, thereby reducing the amount of adipose tissue. Flavonoids and stilbenoids represent the most researched groups of phytochemicals with regards to their effect on adipogenesis, but there are also a number of in vitro and in vivo studies with phenolic acids, alkaloids, and vitamins, as well as other plant compounds. Although phytochemicals like epigallocatechin‐3‐gallate, genistein, and resveratrol reduce lipid accumulation and induce adipocyte apoptosis in vitro and reduce body weight and adipose tissues mass in animal models of diet‐induced obesity, well‐conducted clinical trials are lacking. Pharmacological doses are often used in vitro and when applied in physiological doses in animals or humans, the phytochemicals are often ineffective in affecting adipogenesis. However, by combining several phytochemicals or using them as templates for synthesizing new drugs, there is a large potential in targeting adipogenesis using phytochemicals. © 2010 International Union of Biochemistry and Molecular Biology, Inc.
CHO cell expression, long‐term stability, and primate pharmacokinetics and brain uptake of an IgG–paroxonase‐1 fusion protein
Authors: Boado Ruben J. , Hui Eric Ka‐Wai , Lu Jeff Zhiqiang , Pardridge William M. 
Published: August 2010

AbstractParaoxonase (PON)‐1 is the most potent human organophosphatase known, but recombinant forms of human PON1 have been difficult to produce owing to poor secretion by host cells. In the present investigation, human PON1 is re‐engineered as an IgG–PON1 fusion protein. The 355 amino acid human PON1 is fused to the carboxyl terminus of the heavy chain of a chimeric monoclonal antibody (MAb) against the human insulin receptor (HIR), and this fusion protein is designated HIRMAb–PON1. The HIRMAb part of the fusion protein enables brain penetration of the PON1, which was considered important, because organophosphate toxicity causes death via a central nervous system site of action. A high producing line of stably transfected Chinese hamster ovary (CHO) cells secreting the HIRMAb–PON1 fusion protein in the absence of serum or lipid acceptors was cloned. The bioreactor generated fusion protein was purified to homogeneity with low impurities by protein A affinity chromatography and anion exchange chromatography. The HIRMAb–PON1 fusion protein was stable as a sterile liquid formulation stored at 4°C for at least 1 year. The plasma pharmacokinetics (PK) of the HIRMAb–PON1 fusion protein was evaluated in Rhesus monkeys, which is the first PK evaluation of a recombinant PON1 protein. The fusion protein was rapidly removed from blood, primarily by the liver. The blood–brain barrier permeation of the HIRMAb–PON1 fusion protein was high and comparable to other HIRMAb fusion proteins. Re‐engineering human PON1 as the HIRMAb fusion protein allows for production of a stable, field‐deployable formulation of the enzyme that is brain‐penetrating. Biotechnol.

Under‐recognized soft‐tissue structures inferior and lateral to the head of the clavicle: Anatomy with computed tomography correlation

Published: August 2010

AbstractThis study was undertaken to provide an anatomical explanation for two soft‐tissue structures anecdotally found on axial computed tomography (CT) scan, which are inferior (SI) and lateral (SL) to the head of the clavicle and adjacent to the sternoclavicular joint (SCJ). Three sets of cryosection images were reviewed to identify the anatomical structures corresponding to SI and SL. To demonstrate that SI and/or SL communicate with the SCJ cavity in the living, 312 consecutive chest CT scans were assessed for coexistence of SCJ and SI/SL air. To prove that under‐recognition of SI and SL is due to the use of thick‐section CT scan, another 50 consecutive chest CT scans were evaluated: visibility of SI and SL, and continuity between them on thick (5 mm)‐section images were compared with those on thin (0.75 mm)‐section images. The anterior portions of SI and SL were extensions from the SCJ cavity in the cryosection images, with the articular cartilage and disc occupying variable volumes of SI. The posterior portions of the SI and SL corresponded to the thyroid strap muscles. Air was present in 1 SI, 6 SLs, and 10 SCJs. Four of five patients with SI or SL air had coexisting SCJ air. Thick sections provided significantly poor visibility of SI and SL and continuity compared with thin‐section images. SI and SL are constant shadows on thin‐section CT scan, and their anterior and posterior portions represent extensions of the SCJ cavity and the strap muscles, respectively. The use of thick sections may be responsible for the under‐recognition of SI and SL on CT scan. Clin. Anat. 23:803–810, 2010. © 2010 Wiley‐Liss, Inc.
Structure–Reactivity Relationship Studies for Guanidine‐Organocatalyzed Direct Intramolecular Aldolization of Ketoaldehydes

Published: August 2010

AbstractStructure–reactivity studies are performed to explore the reaction mechanism of the guanidine‐catalyzed intramolecular aldol reaction of ketoaldehydes. A large number of guanidine and guanidine‐like catalysts are synthesized and their properties studied. Kinetic profiles and pKa values of the catalysts are measured and correlated to reaction barriers calculated using density functional theory (DFT). The DFT calculations show that structural rigidity influences the pKa of the guanidines. Although the basicity is a very important factor in the catalysis, it is not sufficient to fully account for its catalytic efficiency. The availability of two aligned nitrogen reaction sites for proton shuttling in the transition state is an essential feature that helps to rationalize the reactivity pattern and the activation mode for this family of organocatalysts.
Methods for the Functionalisation of Nanoparticles: New Insights and Perspectives
Authors: Perrier Thomas , Saulnier Patrick , Benoît Jean‐Pierre 
Published: August 2010

AbstractIn the field of nanometre‐sized drug‐delivery systems, a wide range of colloidal systems have been created in recent decades. All of the systems have a similar global structure, that is, an inner part and an external surface/interface. In several applications, the external interface is the support for desired properties and the basis of future developments. The engineering of the particle’s surface is an emerging step in the design of systems at the nanometre scale. This review presents and summarises the available techniques with a particular attention to recent advances. It is also a base for future works in this expanding area of research.
