Abstract:
AbstractA well-developed theory of evolutionary biology requires understanding of the origins of life on Earth. However, the initial conditions (ontology) and causal (epistemology) bases on which physiology proceeded have more recently been called into question, given the teleologic nature of Darwinian evolutionary thinking. When evolutionary development is focused on cellular communication, a distinctly different perspective unfolds. The cellular communicative-molecular approach affords a logical progression for the evolutionary narrative based on the basic physiologic properties of the cell.Critical to this appraisal is recognition of the cell as a fundamental reiterative unit of reciprocating communication that receives information from and reacts to epiphenomena to solve problems. Following the course of vertebrate physiology from its unicellular origins instead of its overt phenotypic appearances and functional associations provides a robust, predictive picture for the means by which complex physiology evolved from unicellular organisms. With this foreknowledge of physiologic principles, we can determine the fundamentals of Physiology based on cellular first principles using a logical, predictable method. Thus, evolutionary creativity on our planet can be viewed as a paradoxical product of boundary conditions that permit homeostatic moments of varying length and amplitude that can productively absorb a variety of epigenetic impacts to meet environmental challenges.

Abstract:
The term “functionally single ventricle” includes a variety of congenital cardiac anomalies where there is only one ventricle pumping blood to the systemic and pulmonary circulations. The physiology in this arrangement is a considerable challenge for the cardiac specialist, because the complexity encountered in patients with these lesions necessitates particularly specialized medical and surgical management. Patients with such functionally univentricular physiology often respond to common interventions, such as supplemental oxygen, mechanical ventilation, and vasoactive drugs, differently than patients with conventional circulations.1 Furthermore, these patients tend to be encountered more frequently by pediatricians and cardiologists because they undergo multiple operations, may be more adversely affected by intercurrent illnesses, or have chronic cardiac problems requiring frequent attention. A thorough understanding of the complexities of the physiology encountered is thus imperative for the pediatric cardiologist. In this review, we will address important physiologic and anatomic principles that influence care of neonates with functionally univentricular hearts. Although the anatomy and physiology of each reconstructive stage of palliation are unique, we will focus upon the pre- and post-operative physiology as encountered in the neonate.

AbstractAfter delivery, newborns go through a series of physiologic changes in an effort to adapt to extrauterine life, with preterm newborns more likely to experience medical problems following this transition. Neonatal hypothermia, defined as a temperature <36.5°C, is a major contributor to neonatal mortality and morbidity.1 Early bathing may be a contributing factor to hypothermia and interfere with the premature neonate’s ability to safely adapt to an extrauterine environment.2 Skin physiology, the physiologic changes that result from bathing, the importance of maintaining vernix for temperature stability, and how policy change and education-based programs for developmentally supportive care will be discussed in an attempt to improve patient care outcomes for neonates in the NICU.

Abstract:
Background: Cardiac surgery is, by definition, a “non-physiologic” intervention associated with systemic adverse effects. Despite advances in surgical technique, cardiopulmonary bypass (CPB) technology as well as anaesthesia management and patient care, there is still significant morbidity and subsequent mortality. Aim: We consider that the contemporary demand for further improving patient outcome mandates the upgrade from optimal perfusion during the procedure as the gold standard to the concept of a “more physiologic” cardiac surgery. Our policy is a multidisciplinary perioperative strategy based on goal-directed perfusion throughout surgery incorporating in-line monitoring. This translates to “prevent rather than correct” malperfusion through real-time adjustment rather than correction of derangement detected late by incremental evaluation. Method: The strategy is based on continuous monitoring of cardiac index, SvO2, DO2i, DO2i/VCO2i and rSO2. Data acquisition is followed by action when needed; this includes stepwise: transfusion, increase of cardiac output and initiation of inotropic/vasoactive support. Moreover, implementation of minimally invasive extracorporeal circulation (MiECC) is considered as a fundamental component of physiologic perfusion when on-CPB, providing improved circulatory support and end-organ protection. Conclusion: We consider that, with this strategy which establishes optimal perfusion perioperatively, we attain the goal of a “more physiologic” cardiac surgery.

Abstract:

The popularity of the concept of patient-career rose at the same time as more people were using chiropractic care in the United States. Yet, patient-career has yet to be applied in a sociological manner to those who seek out chiropractic care. Semi-structured in-depth interviews with 19 patients of chiropractic care reveal that pain, to the point of interference with daily-life, is what drove them to seek out help outside traditional medicine. This research investigates how holding preconceived notions of chiropractic care (positive or negative), the influence of social networks, and beliefs surrounding health and pain influence the direction of the individual careers in chiropractic care. Several key findings emerged throughout the interview process such as understanding the impact of pain on daily-life, the validation of this pain from a caregiver, the importance of connections and shared understandings in healthcare, and the paradox of a chiropractic adjustment as a blend of science, religion, and magic.

Abstract:
Study of the Arabidopsis thaliana knockout mutant lacking Lhcb3 (koLhcb3) have revealed a close similarity to the wild type plants. Growth rate, NPQ, qP, Φ(PSII), circular dichroism spectra, pigment composition and content of LCHII trimers have been found to be unaffected by this mutation. The proteomic analysis shows only some minor increases in the amount of Lhcb1 and Lhcb2. PAM fluorometry revealed a significant increase in the rate of the state 1 to state 2 state transition in the koLhcb3. None the less, the extent of state transition is identical to wild type. Alterations in the PSII-LHCII supercomplex structure have been demonstrated as well. The M-trimer was found to be rotated ~21° CCW. This altered binding of the LHCII M-trimer is likely the cause of the altered affinity resulting in the increased rate of state transition. Proteomic analysis of the phosphorylation of LHCII revealed a significant increase in state 1 and 2 LHCII phosphorylation relative to wild type. Investigation whether phosphorylation or the altered LHCII binding is the cause of the accelerated rate of state transition have not been conclusive so far. A Lhcb6 depleted mutant (koLhcb6) showed a significant alteration of the PSII-LHCII supercomplex structure and photosynthetic acclimation processes. The LHCII M-trimer is depleted in the PSII-LHCII supercomplexes causing the state transition process to be “stuck” in state 2 and the mutants ability to preform NPQ is inhibited as well. The Lhcb6 protein was concluded to be essential for the binding of the LHCII M-trimer to the PSII core as well as energy transfer. The depletion of LHCII M-trimer was linked to the reduced ability to photoacclimate using NPQ as well.

Abstract:
Two thousand and twelve marked the fortieth anniversary of Title IX and the first Summer Olympic Games in which all attending nations sent female competitors. Too often, scholars of sport history conservatively frame the experiences of girls and women within a narrative of progress. College women's sport participation in particular is framed as a linear narrative beginning with the "new woman's" foray in college physical training, the non-competitive interwar coed, and the post Title IX female athlete. It is within this narrative that the college play day, a sport practice emerging in California and Washington in 1926 began to gain momentum as an additional form of extramural competition for college women. In this dissertation I interrogate which historical and societal forces contributed to the invention, diffusion, and evolution of the college play day. Though the play day is briefly included in descriptive narratives about women's physical activity and sport during the interwar era, deeper explorations are absent. This study aims to further elucidate the extent and variety of forms that the play day took. I aim to explore its general value within the college setting and its reception among women physical educators, colleagues, and play day participants. An additional research question I pose is what are the roles and contributions of certain individuals, alliances, and organizations involved in the invention, adoption, and evolutions of the college play day? Last, I question whether or not the play day is a site in which gender relations or other intersecting relations of power were reproduced, constructed, or transformed?

Abstract:
O carrapato bovino Boophilus microplus está presente em áreas tropicais e subtropicais no mundo e é um ectoparasito hematófago que causa inúmeras perdas à bovinocultura, através da espoliação ao bovino ou das doenças que transmite como vetor. Atualmente, o principal método de controle empregado baseia-se em produtos químicos, que são onerosos e contaminam o ambiente. Estudos a respeito da ecologia, comportamento e fisiologia de B. microplus são importantes para o desenvolvimento de novos métodos de controle do carrapato. A resposta ao estresse oxidadivo e a morte celular programada, examinadas neste estudo, permitem compreender melhor os mecanismos fisiológicos usados pelo carrapato adulto e seus ovos e larvas para sobreviver no ambiente. A resposta a estresse oxidativo foi analisada em ovos e larvas. A atividade de GST e outras moléculas envolvidas em mecanismos de proteção contra estresse oxidativo variaram dependendo do tempo transcorrido após a postura e eclosão. A cinética do consumo de oxigênio apresentou correlação positiva com o aumento na atividade de GST durante a embriogênese. Um alto conteúdo de substâncias reativas ao ácido tiobarbitúrico foi observado em extratos de ovos e larvas, indicando que carrapatos apresentam alto estresse oxidativo durante a embriogênese e desenvolvimento larval. Além disso, a atividade de GST apresentou forte correlação com peroxidação de lipídeos, uma indicação de seu papel na defesa antioxidante em ovos. Com o objetivo de melhor caracterizar o processo de morte celular, que elimina tecidos não mais necessários e leva à degeneração de glândulas salivares, ovários e singânglios, foi feita uma investigação usando ensaios de visualização de fragmentação de DNA em gel de agarose, teste cometa e TUNEL e a ativação da via apoptótica foi analisada usando ensaio de caspase. A fragmentação de DNA e a atividade enzimática de caspase-3 foram observadas em glândulas salivares e ovários 48 e 72 h após a remoção do carrapato do hospedeiro; em singânglios estes parâmetros foram mantidos em baixos níveis após 48 h. Estes resultados obtidos sugerem que há um controle refinado de manutenção de tecido através de apoptose.
The cattle tick Boophilus microplus is present in tropical and subtropical areas in the world and it is a haematophagous ectoparasite that causes several losses to cattle breeding, through the bovine exploiting and diseases transmitted. Currently, the main control method is based on chemicals, which are expensive and contaminate the environment. Studies about ecology, behavior and physiology of B. microplus are important to develop new methods for the tick control. The data examined in this study allow understanding the physiologic mechanisms used by the tick, eggs and larvae to survive in the environment. For this, the oxidative stress response in eggs and larvae and the cell death in different tissues of adult tick females during the pre-oviposition period were analyzed. The oxidative stress response was analyzed in eggs and larvae and the results showed that the GST activity and other molecules involved in mechanism of protection against oxidative stress varied depending on the time elapsed after oviposition and eclosion. A positive correlation was observed between the oxygen consumption kinetics and the increase in GST activity during embryogenesis. A high content of thiobarbituric acid reactive substances were observed in egg and larva extracts, indicating that ticks face high oxidative stress during embryogenesis and aging. In addition, GST activity presented strong positive correlation with lipid peroxidation, an indication that it plays a role in oxidant defences in eggs. In order to better characterize the cell death process that eliminates unnecessary tissues, the degeneration of salivary glands, ovaries and synganglia was investigated using DNA fragmentation in agarose gel, comet and TUNEL assays, and apoptosis activation pathway by the caspase assay. DNA fragmentation and enzymatic activity of caspase-3 were observed in salivary glands and ovaries at 48 and 72 h after tick removal from the host; in synganglia these parameters were maintained at low levels upon 48 h. These results obtained suggest that there is a refined control of tissue maintenance through apoptosis.

Abstract:
PrPc é uma glicoproteína de 35 KDa, bastante conservada entre as espécies e essencial no processo de transmissão e patogênese de várias doenças neurodegenerativas como a encefalopatia espongiforme bovina e a doença de Creutzfeldt-Jacob (PRUSINER, 1991). Embora sua função fisiológica ainda seja desconhecida, sabe-se que a patogênese das doenças priônicas requer a sua expressão e é freqüentemente acompanhada do acúmulo no cérebro de uma isoforma anormal de PrPc, designada PrPsc (GABIZON e cols., 1997). Interessado nos possíveis papéis fisiológicos da proteína PrPc, nosso grupo tem se dedicado a estudar as interações que PrPc realiza com outras moléculas. Identificamos e caracterizamos duas interações nas quais PrPc está envolvido: com uma proteína ligante de 66 KDa, recém-identificada como sendo a proteína STI1 (ZANATA e cols., 2002) e com a principal proteína não colagênica da matriz extracelular, a laminina (GRANER e cols., 2000). No presente trabalho, procuramos investigar as vias de sinalização deflagradas por cada uma dessas interações, como também o seu papel nos mecanismos de morte celular programada e memória. Os resultados apresentados nesse trabalho demonstram que a interação PrPc-p66 desencadeia uma resposta neuroprotetora na camada neuroblástica da retina de roedores em desenvolvimento via cAMP/PKA. Além disso, verificamos que a interação PrPc-laminina desempenha um importante papel na formação da memória de curta duração através da ativação da via cAMP-PKA-MAPK, e na memória de longa duração ativando somente a via cAMP/PKA.
PrPc is an extremely conserved 35 KDa glycoprotein which seems to be essential during the transmission and pathogenesis of several neurodegenerative diseases like bovine spongiform encephalopathy or Creutzfeldt-Jacob disease (PRUSINER, 1991). Although the physiological function of this protein remains unclear, it is well established that prion diseases require PrPc expression and are often characterized by deposition of an abnormal PrPc isoform, named PrPsc (GABIZON et. al., 1997). Interested in the normal fuction of PrPc, our group has been dedicated to study the interations that PrPc could entertain with other molecules. We have identified and characterized two interactions in which PrPc is involved: with a 66 KDa ligand protein, recently identified as the STI1 protein (ZANATA et. al., 2002) and with laminin (GRANER et. al., 2000). In this work, we have investigated the signaling pathways triggered by these interactions, as well as their relevance in programmed cell death and memory formation mechanisms. We show in this work that PrPc-p66 interaction transduces neuroprotective signals through a cAMP/PKA-dependent pathway in the neuroblastic layer of rodents\' retina. Moreover, we demonstrated that PrPc-laminin interaction has an important role for short-term memory formation through the activation of cAMP-PKA-MAPK pathways and for long-term memory with the activation of the cAMP/PKA pathway only.

Abstract:
This practice based research focuses on events of the body, using the participating observer-researcher's experiences of medical events undertaken by her within a western medical environment to investigate her living existence as a 'unit', an 'experiencing corporeal body'. The project addresses a sharp awareness of body experienced by the researcher. It investigates this body in terms of the literal posthuman associated with Moravec, alongside the theoretical posthuman associated with Hayles where the 'defining characteristics involve the construction of subjectivity'. Using action research as the methodology and video installation as practice the project considers the position of the researcher in relationship to the medics, a situation of subject / object. With the female participating researcher as a given it becomes relevant to reference ideas from the ideals of feminism and to consider the question 'are women human?' The project produces evidence of change in the relationship of subject / object specific to this research when the researcher actively engages with attributes of the posthuman and it demonstrates how an altered emerging subject resulted from this engagement. There is a movement for the researcher from a liberal humanist subject to an emerging posthuman subject, an empowering and emancipating change.

Abstract:
AbstractThe changing climate and water availability strongly affect the current state of agricultural production. While the global temperature rises, the occurrence of extreme climatic conditions becomes erratic. This current scenario has driven the development of rice varieties and cultivation practices that require less water and favor mechanization. Although puddled transplanted rice has been more widely used in the past, direct seeding has been gaining popularity in recent years, especially due to its water- and labor-saving features. This technique allows full crop establishment from seeds that were directly sown in the field, thus avoiding puddling, transplanting, and maintaining standing water. Consequently, it offers promising positive environmental effects including decreasing the release of greenhouse gases and increasing water-use efficiency. Historically, rice varieties bred for transplanting are also used in direct seeding, which limits the maximum yield potential of field trials. The success of direct seeding relies strongly on the development of rice varieties with robust crop establishment. Anaerobic germination, seed longevity, and early seedling vigor are the key traits required to achieve this. This chapter expounds on the physiology, molecular mechanisms, genetics, and relevance of the enumerated traits for direct seeding. A brief discussion of breeding for rice varieties with improved germination under direct seeding is also provided.

Abstract:
Abstract Animal breeding for welfare and sustainability requires improving and optimizing environmental impact, productivity, robustness and welfare. Breeding is a long-term exercise at the start of the food chain with permanent cumulative outcomes, disseminated widely. This chapter explains, with a focus on poultry, breeding programme design and how broadening breeding goals and managing trait antagonism results in balanced breeding and more robust animal populations. Breeding progress in skeleton and skin health, physiology and body composition, and behaviour are addressed. The economic impact of welfare and environmental improvements is worked out, and the ethical and societal aspects of genetic improvement are put into perspective. The consideration of feedbacks of all stakeholders, including customers and the wider society, is crucial. For each crossbreed, breeders will continue to improve overall welfare, health, productivity and environmental impact, but between the crossbreeds there will be clear differences answering specific demands of concepts and brands.

Abstract:
Physiologist Claude Bernard lived in a time when very little was known about the mechanisms underlying physiologic findings, and he had ample access to clues garnered from observing machines. Let's consider homeostasis (a concept championed by Bernard), an example for which an engineered machine shed light on a fundamental principle of physiology. Homeostasis is simply the tendency of the body to maintain important physiologic variables (eg, heart rate, blood pressure, PACO2) at constant, preset values. An example is a simplified mechanical governor that could be used to regulate the rotational speed of a steam engine shaft. ‘Autoregulate’ might be a more apt word because the governor performs without external help or guidance, provided it is designed and built properly. It doesn't take much imagination to see an analogy between the mechanical governor and the autonomic nervous system. Both maintain specific variables at a constant set point through a process of feedback loops.

Abstract:
As the number of end-stage heart failure patients steadily grows, more patients are implanted with long-term left ventricular assist devices (LVAD). Increasingly, noncardiac-trained anesthesiologists are caring for LVAD patients presenting for noncardiac surgery. While continuous-flow LVAD physiology creates unique physiologic and management challenges, patients can be safely anesthetized with appropriate education and training. A multidisciplinary team approach is recommended to review potential perioperative issues for each LVAD patient, including cardiovascular status, LVAD function, anticoagulation, and antibiotic prophylaxis. The anesthesiology team should be comfortable managing hemodynamic instability, arrhythmias, and cardiac arrest in LVAD patients. This chapter uses a case study of an LVAD patient presenting for noncardiac surgery as an example.

Abstract:
Pregnancy results in physiologic changes that bring added stress to the body. Changes in cardiovascular hemodynamics, respiratory physiology, coagulation profile, hormonal concentrations, and endothelial function can result in the perfect storm for cerebrovascular dysfunction. Cerebrovascular disorders of pregnancy can be grossly simplified to disorders that arise from thrombosis, hemorrhage, and/or hypertension. Care of these patients become more complex when considering the effects of therapy on the fetus. The age of the fetus comes into play as well as pharmacologic agents that cross the placenta and may potentially harm the fetus. Ultimately, the priority for the clinician is to provide life-saving care to the patient even if it is at the expense of the fetus. In rare cases where despite best medical management practices the patient develops brain death or is vegetative, the decision to continue life support to allow further development of the fetus becomes an ethically complex situation.

Abstract:
In physiologic terms, we are exposed to 3 main sources of pressure: 1) the weight of the atmosphere; 2) hydrostatic forces exerted by the weight of body fluids; and 3) mechanical pressure generated by the heart or other muscles that contract around those fluids. Because cardiopulmonary physiology deals so much with pressure measurements, let's start by defining what pressure really is. Simply put, pressure is force divided by area. It's also important to understand what pressure is not. For example, pressure is not energy. Only when pressure is coupled to a volume change (ie, movement or pressure-volume work) is it a component of energy. This is more than just a semantic point. Although we're fond of saying that fluids move from high to low pressure, that isn't always true. The reason why highlights a fundamental difference between pressure and energy. Pressure is surprisingly difficult to measure. Often, when we think we are measuring pressure, we are actually measuring stretch or movement.

Abstract:
Upon clinical analysis, regions such as curvatures and bifurcations have been characterized as high prone regions where atherosclerotic plaques were more likely to occur. Biological studies have linked this phenomenon to the localized response of the endothelial cells to mechanical blood flow forces such as fluid shear stress. Present common in vitro flow cell culture models such as parallel-plate flow chambers and cone and plate viscometers used to study endothelial cell response depict a simplified geometry and thus, unrealistic in vivo conditions. The aim of this project was to develop a more realistic in vitro cell culture model by using an anatomically correct right coronary artery model and a more physiologic flow environment for dynamic endothelial cell culture experiments.

Abstract:
Native heart valves with limited functionality are commonly replaced by prosthetic heart valves. Since the first heart valve replacement in 1960, more than three million valves have been implanted worldwide. The most widely implanted prosthetic heart valve design is currently the bileaflet mechanical heart valve (BMHV), with more than 130,000 implants every year worldwide. However, studies have shown that this valve design can still cause major complications, including hemolysis, platelet activation, and thromboembolic events. Clinical reports and recent in vitro experiments suggest that these thrombogenic complications are associated with the hemodynamic stresses imposed on blood elements by the complex non-physiologic flow induced by the valve, in particular in the hinge region.

Abstract:
Sensors are an integral part of many engineered products and systems. Biological inspiration has the potential to improve current sensor designs as well as inspire innovative ones. Mimicking nature offers more than just the observable aspects that conjure up engineering solutions performing similar functions, but also less obvious strategic and sustainable aspects. This paper presents the design of an innovative, biologically-inspired chemical sensor that performs “up-front” processing through mechanical filtering. Functional representation and abstraction were used to place the biological system information in an engineering context, and facilitate the bioinspired design process. Inspiration from the physiology (function) of the guard cell coupled with the morphology (form) and physiology of tropomyosin resulted in multiple concept variants for the chemical sensor. The chemical sensor conceptual designs are provided along with detailed descriptions. Applications of the sensor design include environmental monitoring of harmful gases, and a non-invasive approach to detect illnesses including diabetes, liver disease, and cancer on the breath.

Abstract:
Since the introduction of the Edmonton Protocol in 2000, islet transplantation has been emerging as promising therapy for Type I diabetes mellitus (T1DM) and currently is the only therapy that can achieve glycemic control without the need for exogenous insulin. Transplanting islet cells has several advantages over transplanting a whole pancreas in that it involves only a minor surgical procedure with low morbidity and mortality, and at a significantly lower cost. However, an obstacle to realizing this goal is a lack of an islet potency index as required by the U.S. Food and Drug Administration (FDA) biologics licensing, as well as a more complete understanding of the physiological mechanisms governing islet and β-cell physiology. Recently, the University of Illinois at Chicago (UIC) has developed a microfluidic platform that can mimic in vivo islet microenvironments through precise and dynamic control of perifusing culture media and oxygen culture levels; all while measuring functionally relevant factors including intracellular calcium levels, mitochondrial potentials, and insulin secretion. By developing an understanding of the physiology and pathophysiology of islets we can more effectively develop strategies that reduce metabolic stress and promote optimization in order to achieve improved success of islet transplantation and open new clinical avenues. The presentation begins by introducing key issues in the field of pancreatic islet transplantation as a clinical therapy for T1DM. This is followed by brief review various technologies that have been developed to study islet cells. The presentation then describes the design, application, and evolution of UIC’s microfluidic-based multimodal islet perifusion and live-cell imaging system for the study of pancreatic islet and β-cell physiology. The article then concludes presenting initial findings from studies seeking to develop an islet potency test.

Abstract:
Complications associated with abnormalities of the ascending and thoracic aorta are directly influenced by mechanical forces. To understand hemodynamic alterations associated with diseases in this region, however, we must first characterize related indices during normal conditions. Computational fluid dynamics (CFD) models of the ascending and thoracic aorta to date have only provided descriptions of the velocity field using idealized representations of the vasculature, a single patient data set, and outlet boundary conditions that do not replicate physiologic blood flow and pressure. Importantly, the complexity of aortic flow patterns, limited availability of methods for implementing appropriate boundary conditions, and ability to replicate vascular anatomy all contribute to the difficulty of the problem and, likely, the scarcity of more detailed studies.

Abstract:
Abstract The mechanical and structural characteristics of aortic media have profound effects on the physiology and pathophysiology of an aorta. However, many aspects of the aortic tissue remain poorly understood, partly due to the intrinsic layered wall structure and regionally varying residual stresses. Our recent works have demonstrated that a mechanical interaction between the elastic lamina (EL) and smooth muscle layer in the aortic media can be computationally reproduced using a simplified finite element (FE) model. However, it is questionable whether the simplified FE model we created was representative of the structure of a real medial wall and its modeling technique would be applicable to develop a more sophisticated and structure-based aortic FE model. This study aimed to computationally represent EL buckling in the aortic medial ring at an unloaded state and successfully reproduced transmural variation in EL waviness across the aortic wall. We also aimed at confirming the inner and outer layers of the medial wall are subjected to compressive and tensile residual stresses, respectively, at the unloaded state, implying that the ring model will open spontaneously when it is radially cut. Moreover, the computed residual stresses were found to be within the reasonable range of the predicted values, 1–10 kPa, supporting the validity of our modeling approach. Although further study is required, the information obtained here will greatly help improve the understanding of basic aortic physiology and pathophysiology, while simultaneously providing a basis for more sophisticated computational modeling of the aorta.

Full text
Abstract:
Mechanical test samples are often characterized using time-varying loads, either through slow monotonic changes in quasi-static testing, or through more rapid cyclic changes in dynamic testing. Spinal implant static and fatigue strengths are typically evaluated using such protocols, including such as standards ASTM F1717, ASTM F2077, and ASTM F2346. In contrast, wear tests such as ASTM F2423 and ASTM F2624 and ISO 18192-1, apply a single set of loading parameters over millions of cycles. These parameters are selected based on known, but limited, physiologic data. Wear tests however may be very sensitive to input parameters. Moreover, variations in surgical technique, patient anatomy, and pathology greatly alter the loading environment on the device. Wear tests ideally would evaluate the device under both the expected duty cycle as well as under varying test parameters.

Full text
Abstract:
Long before mitral valve replacement (MVR) became a routine operation, physiologic studies indicated that the continuity of mitral leaflets with papillary muscles, chordae tendineae (CT) and the atrioventricular ring may play a decisive role in the function of the left ventricle (LV) [1]. This led Lillehei et al. [2] to establish a procedure whereby the posterior leaflet, its CT and papillary muscles were preserved in MVRs. These and other studies indicated a significant reduction of postoperative mortality compared to conventional MVR. Though developed in the early 1960s by Lillehei, the technique of chordal preservation was not initially accepted. It wasn’t until 1983 that surgeons began to revive the concept of MVR with preservation of the CT. As this technique became more widely known, many clinical studies were performed; however, very few have been conducted which examine the effect of leaflets and CT on flow dynamics.

Abstract:
Cervical corpectomy is a procedure most commonly indicated for resection of metastatic disease in the vertebra, access to the spinal cord tumors and inflammatory or infectious lesions.[1] Posterior occipitocervical instrumentation with rods and lateral mass screws has been shown to be a rigid fixation technique in this region [2] and, small diameter rods are thought to be lighter weight, less prominent and less likely to be associated with screw pullout.[3] Still, deformity imposed upon small diameter rods, by the weight of the head, the cervical spine, and spinal ligaments has yet to be quantified. Anecdotal observations show that the rods lose their lordotic curvature and patients fuse in a kyphotic curve making daily living more difficult. The goal of this study is to examine the mechanical behavior of these rods in situ under physiologic loading conditions reflective of activies of daily living.
