Abstract:

The kidney is a vital organ within the human body and improvements in the ability to characterize the kidney tissue can create benefits for patients with kidney tumors and for kidney transplant recipients. Often, changes in tissue health or development of cancer are manifested in changes in tissue structure that affect tissue elastic properties. For example, the cancerous tissue of renal cell carcinoma is stiffer than healthy kidney tissue, and the development of fibrosis, which impairs kidney function, also causes the tissue to become stiffer over time. These changes can be imaged with ultr

Abstract:

Reperfusion injury may mediate renal dysfunction following ischaemia. A murine model was developed to investigate the role of the tissue factor-thrombin-protease activated receptor pathway in renal ischaemia reperfusion injury (IRI). In this model, mice received 25 minutes of ischaemia and subsequent periods of reperfusion. C57BL6, protease activated receptor-1 (PAR-1) knockout mice, and tissue factor (TF) deficient mice were used. Following 24 hours IRI, PAR-1 deficiency resulted in protection against severe renal failure compared to the C57BL6 mice (creatinine, 118.2 ?? 6.3 vs 203 ?? 12 ??mo

Abstract:

Background and aims: End stage renal disease (ESRD), an increasing global major public health problem, has greatly increased cardiovascular disease risk (CVD) than the general population for unknown reasons. Preliminary data suggest that adipose tissue, shown to contribute to CVD risk in non-ESRD populations, may also play a part in ESRD. Adipose tissue is a complex organ which not only functions as a fat storing depot, but also plays an essential role in lipid metabolism. Recently, researchers have recognized that adipose tissue is also an endocrine organ since it secretes several cytokines a

Abstract:

Human epidemiological studies have indentified obesity as an independent risk factor for renal disease. In addition, maternal nutrient restriction (MNR) during gestation results in a series of adaptations that may predispose those offspring to obesity and hypertension. Recent reports demonstrated that obese sheep exposed to MNR during early to mid gestation have a predisposition to ectopic lipid deposition in the heart and a rise in necrotic adipocytes, which are markers of severe metabolic dysfunction. Surprisingly, in this model of MNR, the renal tissue of those offspring showed an apparent

Abstract:

Acute renal failure (ARF) is a common condition on the intensive care unit (ICU) and may affect up to 40% of patients (de Mendonca, A. et al., 2000), (Korkeila, M. et al., 2000). Pathophysiological mechanisms remain unclear. Patients who die from sepsis have kidneys that look histologically normal (Hotchkiss, R.S. et al., 1999), while the renal prognosis in survivors is good with < 2% requiring long-term renal replacement therapy (Noble, J.S. et al., 2001). This has led some authors to suggest that acute renal failure is a physiological process designed to shut down vital processes and protect

Abstract:

Introduction. Connective tissue growth factor (CTGF) is the only CCN member recognized as a mediator of chronic fibrotic disease. Accumulating evidence suggests that CTGF is important as a downstream effector of transforming growth factor (TGFβ) in modulating a sustained pro-fibrotic signal in in vivo models. Moreover, in cultured human proximal tubule epithelial cells (PTECs) CTGF mRNA is readily upregulated by TGFP and the nascent protein accumulates extracellularly. How pro-fibrotic signalling occurs is yet to be ascertained but it likely involves extracellular interactions with secreted CT

It is estimated that approximately one in fifteen Americans, nearly 20 million people, experience chronic kidney disease with most of those diagnosed progressing to kidney failure. The ultimate treatment available for end stage renal failure is whole kidney transplantation. However, there are very few kidneys available for patients to receive and those patients who are fortunate enough to receive an organ must remain on immunosuppressive medication for the remainder of their lives.

Abstract:

Involving patients in medical decisions by acknowledging patients personal values and individual preferences has become an important goal of providing ethical medical care. Despite a general movement towards a model of shared decision-making, many patients do not fully meet their preferred role in practice. The decision whether or not to accept a kidney once it is offered to a patient awaiting transplant has historically been made predominantly by the transplant surgeon with little involvement from the patient. Because dialysis can provide long-term renal replacement, declining a kidney is a v

Abstract:

Introdução: Doador de rim em vida é uma importante fonte de órgão para os pacientes portadores de doença renal crônica (DRC). Os doadores experimentam uma redução abrupta da taxa de filtração glomerular (TFG) e adaptações ao metabolismo mineral demandam estudos nesta população. Nós avaliamos prospectivamente esta adaptação em doadores de rim em vida. Métodos: Entre janeiro de 2010 a agosto de 2011, no hospital das Clínicas de São Paulo e na Universidade de Miami, realizamos a avaliação prospectiva do metabolismo mineral e da função renal por 1 ano em 74 doadores de rim em vida. Medimos a taxa

Abstract:

The nervous system may be simulated as a network of model neurons as a means to understand the function of the brain. Complex as the mammalian nervous system is, such simulations of any significant scale are computationally and energetically expensive. SpiNNaker is a computer architecture designed to advance the feasible scale of neural tissue models using fifty thousand chips, each containing eighteen low-power processors, to model one billion neurons and one trillion synapses in real-time. This dissertation demonstrates the success of prototype hardware with detailed models of the rodent som

Abstract:

The thesis reports on 6 studies (2 of which were part of a multi-centre trial) examining hydration and fluid balance. The first study described in this thesis investigated the impact of hydration status on Dual energy x-ray absorptiometry (DXA) and other methods that are popular tools to determine body composition in athletes. We observed that it is important to ensure a euhydration when assessing body composition, particularly when considering changes associated with nutritional or exercise interventions. The second and third studies reported identified beverages that promote longer term flui

Abstract:

Malaria remains one of the world's major health problems, especially in developing countries. A better understanding of the pathology and pathophysiology of severe malaria is key to develop new treatments. Different approaches have been used in malaria research including the in vitro co-culture models with endothelial cells and both murine and simian animal models. However these are open to controversy due to disagreement on their representativeness of human disease. Using human post-mortem tissue in malaria research is another important approach but is practically challenging, limiting the av

Abstract:

Modéliser la déformation de structures anatomiques en temps réel est un problème crucial en simulation médicale. En raison des grandes différences existantes dans leur forme et leur constitution, un modèle unique est insuffisant face à la variété des comportements mécaniques. Par conséquent, nous avons identifié deux principaux types de structures: les organes pleins (cerveau, foie, prostate etc.) et les organes creux (colon, vaisseaux sanguins, estomac etc.). Notre réponse à cette problématique est double. Notre première contribution est une implémentation GPU d'un modèle éléments finis qui e
