Повний текст джерелаLa teneur en matières grasses du porc affecte la saveur de la viande de porc. Dans l'industrie porcine, la graisse intramusculaire (GIM) et la cote de persillage (CP) sont deux propriétés qui déterminent la teneur en gras du porc. Les méthodes conventionnelles de détermination ne sont pas adaptées aux besoins actuels de l'industrie car elles sont destructrices ou subjectives. Cette étude porte sur l'utilisation de l'imagerie hyperspectrale dans l'évaluation de la teneur en graisse intramusculaire et du persillage du porc. Les effets de la répartition de la graisse intramusculaire le long du muscle Longissmus, de la congélation, du dégel et de l'analyse de la forme pour le traitement de l'image ont été pris en compte. Une technique d'imagerie hyperspectrale proche infrarouge (IR) allant de 900 à 1700 nm a été utilisée pour prédire le GIM ou la CP. La viande fraîche au niveau de la 3ème/4ème côte du porc a été utilisée pour recueillir les images hyperspectrales. Des analyses de la forme fondée sur les techniques du filtre de Gabor, du détecteur linéaire à large spectre (WLD) et de la matrice de cooccurrence de niveau gris améliorée (GLCM) ont été étudiées et les propriétés de l'image, i.e spectre, texture et propriétés des lignes, ont été extraites. La régression linéaire multiple (RLM) a été utilisée pour développer des modèles de prédiction. Pour la cote persillage, le modèle de RLM utilisant la moyenne de spectre filtrée pour la première dérivée de Gabor a le mieux performé avec une précision de calibration de 0,90 aux longueurs d'onde de 961, 1186 et 1220 nm. Pour le GIM, une précision de calibration de 0.85 a été obtenue avec un spectre moyen de base à 1207 et 1279 nm. La distribution du contenu de GIM a été illustrée. Les résultats démontrent la possibilité d'utiliser les images hyperspectralces proche IR pour évaluer rapidement et de façon non-destructive le taux de gras intramusculaire du porc. En ce qui concerne le persillage en tant qu'indice visuel, une méthode objective d'évaluation de la cote persillage utilisant des images rouge-vert-bleu (RGB) a été développée en appliquant un WLD basé sur un model linéaire au canal vert. La possibilité d'un contrôle non-destructif du GIM et de la CP utilisant du porc congelé et décongelé a été étudiée. Une précision de la prédiction de 0.90 pour la CP a été réalisée avec du porc congelé. Une précision de la prédiction de 0.82 pour le GIM découle du porc décongelé. Le potentiel du porc congelé et décongelé pour l'évaluation de la cote de persillage et du porc décongelé pour l'évaluation de la teneur en gras intramusculaire a été démontré. Outre l'effet du gel et du dégel, la variation du GIM et de la CP à travers les sept derniers muscles thoraciques Longissmus a été étudiée. Les relations entre le GIM et la CP à la dernière côte et les propriétés correspondantes aux autres côtes et au filet ont été déterminées avec précision. La relation entre les images de proche IR à l'extrémité et le niveau de GIM du porc six dernières côtes thoraciques a été étudiée. Des relations étroite ont été déterminées, en particulier entre les images de l'extrémité de la côte et les taux de GIM aux 2eme/3eme dernières côtes et la 2eme dernière côte.

Повний текст джерелаOs métodos atuais para estimação de gordura hepática por densidade de prótons (PDFF) utilizando imagem de magnitude de ressonância magnética (RM) enfrentam o desafio de estimar corretamente quando a gordura é a molécula dominante, ou seja, PDFF é maior que 50%. Assim, a acurácia desses métodos é limitada a meio intervalo de operação. Apresentamos aqui um método baseado em redes neurais para regressão capaz de estimar pelo intervalo completo de frações de gordura. Construímos uma rede neural baseada nos ângulos e distâncias entre os dados do sinal discreto da imagem de RM (ADALIFE), usando esses atributos associados a diferentes valores de PDFF, com sinais simulados considerando diferentes relações sinal-ruído (SNR). Resultados foram comparados para verificar a repetibilidade e concordância através de análise de regressão, Bland- Altman e curvas de característica de erro de regressão (REC). Resultados para o método Multi-interferência (estado-da-arte) foram similares aos relatados in vivo pela literatura, ressaltando a relevância das simulações. ADALIFE foi capaz de estimar corretamente frações de gordura até 100%, quebrando o paradigma para intervalo completo de operação utilizando apenas processamento posterior à aquisição de imagens ou sinais. Considerando meio intervalo, nosso método superou o estado-da-arte em termos de repetibilidade e concordância, com limites mais estreitos e menor erro esperado em qualquer SNR.

Повний текст джерелаObesity is associated with increased morbidity and mortality linked to many diseases, including type 2 diabetes, hypertension and disease nonalcoholic fatty liver. Recently, 1H magnetic resonance imaging (MRI) has emerged as the method of choice for non-invasive fat quantification. In this thesis, MRI methodologies were investigated for in vitro (MR phantoms) and in vivo (mice) measurements on a 4.7T preclinical scanner. Two algorithms of fat quantifications – the Dixon’s method and IDEAL algorithm – were considered. The performances of the IDEAL algorithm were analyzed as a function of tissue properties (T2*, fat fraction and fat spectral model), MRI acquisition parameters (echo times, number of echoes) and experimental parameters (SNR and field map). In phantoms, the standard approach of single-T2* IDEAL showed some limitations that could be overcome by optimizing the number of echoes. A novel method to determine the ground truth values of T2* of water and T2* of fat was here proposed. For in vivo measurements, different analyses were performed using the IDEAL algorithm in liver and muscle. Statistical analysis on ROI measurements showed that the optimal choice of the number of echoes was equal to three for fat quantification and six or more for T2* quantification. The fat fraction values, calculated with IDEAL algorithm, were statistically similar to the values obtained with Dixon’s method. Finally, a method for generating reference signals mimicking fat-water systems (Fat Virtual Phantom MRI), without using physical objects, was proposed. These virtual phantoms, which display realistic noise characteristics, represent an attractive alternative to physical phantoms for providing a reference signal in MRI measurements

Повний текст джерелаBackground: Fat grafts have been used for a long time as a filling material for correction of soft tissue defects. There is growing interest in the use of fat grafting as a method of breast reconstruction in patients undergoing surgery for breast cancer. Fat is considered an ideal filler material due to its easy availability and low immunogenic and allergic reaction and because it is an autologous material. However, fat grafts often have high rates of reabsorption and replacement by fibrous scar tissue, calcifications or oily cysts, which can generate sequels and difficulties in the interpretation of radiological images of the breast. Based on the technique developed by Coleman, several studies have emerged showing the efficacy of fat grafting and that it does not seem to interfere with the early diagnosis of breast cancer. Studies have shown that the incidence of mammographic changes after fat grafting does not differ from other surgical procedures of the breast and that they are easily interpreted as benign changes by experienced radiologists in breast imaging. Aim: Analyze mammographic changes in fat grafting performed during conservative surgery for breast cancer and subsequently followed by radiotherapy. Methods: A total of 171 patients diagnosed with early-stage cancer who received conservative treatment and radiotherapy at the Hospital de Clínicas de Porto Alegre from June 2010 to July 2013 were followed in the present study. Thirty-eight of these also underwent immediate reconstruction with fat grafting, as described by Coleman. Results: Mean patient age was 58.9 years for those not exposed to lipomodeling, and 52.5 years in the remainder of the sample. The mean graft volume was 125 ml. In the present study, oncological follow-ups at 6, 12, 18 and 24 months revealed a higher incidence of benign mammographic findings, such as oil cysts and steatonecrosis, in women who had undergone lipomodeling. However, no between-group differences were identified on any other radiological parameter, including scarring, nodules, suspicious findings and BI-RADS categories. Conclusion: These findings suggest that the mammography alterations caused by lipomodeling are easily identified as benign, and that this procedure is not associated with an increased incidence of inconclusive or suspicious findings. This is a unique study because breast reconstruction with fat is conducted at the time of conservative surgery.

Повний текст джерелаThe high prevalence of metabolic and cognitive disorders represents one of the major issues of health systems. Recent findings indicate that obesity may affect brain functions however the effect of a high-fat diet (HFD) on the central nervous system is not fully understood. The aim of this study is the evaluation of the influence of HFD on neuroinflammation and regional brain function in a mouse model of Insulin Resistance (IR) focusing on sex-dependent differences induced by peripheral metabolic impairment. C57BL/6J male and female mice were fed with standard chow or HFD (45%/60%) for 35 weeks. Animals were monitored weekly for body weight, haemato-chemical analysis (circulating glucose, total cholesterol, ALT, and AST), and glucose tolerance test (GTT). Positron Emission Tomography (PET) imaging studies were performed longitudinally using [18F]-FDG and [18F]-VC701 as radiotracers, to measure respectively glucose consumption and microglia/macrophages activation within the brain. Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy (MRS) was used to measure the effects of diet on hepatic lipid content and peri abdominal fat accumulation. Finally, post-mortem transcriptome analysis was applied to the anterior cortex to reveal potential modification in gene expression. HFD induced a significant increase in body weight, glucose tolerance, and haemato-chemical parameter in a sex dependent manner. HFD diet increased peri abdominal fat accumulation in male and lipid content in the liver as revealed at MR spectroscopy. This last effect was particularly evident in females. PET [18F]-FDG showed a relative increase in glucose metabolism in the anterior region of the brain including the olfactory bulbs in both male and female mice while an increase in the anterior cortex was found in males mice fed with 60% HFD. Moreover, correlation analysis between glucose uptake and different metabolic biomarkers revealed, mainly in male mice, regional brain metabolic modifications associated with BMI values and haemato-chemical parameters. [18F]-VC701-PET showed a general trend toward an increase of tracer uptake all over the brain after diet consumption in both male and female HFD mice. Anterior cortex transcriptome analysis showed a common de-regulation of genes related to nervous system development but also sex-specific modifications. Our finding suggests that HFD induced obesity in adult mice causes a general metabolic impairment not confined in the periphery but involving also selected brain regions. The increased binding of the activated microglia associated with TSPO radioligand suggests that obesity can induce a diffuse neuro-inflammatory reaction in mice's brains. PET imaging technique is permitted to identify the presence of metabolic derangement and the neuro-inflammatory response of mice brain induced by HFD. This finding is relevant since our model reproduces the peripheral metabolic modification typical of IR and type 2 diabetes.

Повний текст джерелаImproving the management of cardiac complications in metabolic diseases, obesity and diabetes, is a major challenge for our society. The measurement of epicardial adipose tissue (EAT), a fat depot attached to the heart, is an emerging and promising diagnosis to identify patients at risk. We developed the automation of this measurement on routine MRI images by deep learning. Then, an innovative MRI technique was proposed to measure and characterize the EAT in 3D, combining: a free-breathing acquisition, an image reconstruction robust to cardio-respiratory motion and MRI imperfections, an optimized and validated fat characterization algorithm and the knowledge of the composition of ex-vivo EAT samples. Together, this allows for in vivo, non-invasive characterization of EAT, a novel diagnosis for cardiometabolic risk

Повний текст джерелаThe objective of this work is the development and implementation of methodologies of images for Nuclear Magnetic Resonance, for reduction of the time of acquisition, since in the conventional clinical examinations this time is very superior to the used one in these sequences, that are of the order of T_ 2 , these sequences is based on the only sweepings of the space-k, conventionally called Echo Planar Imaging. The intentions of use of this methodology understand since conventional clinical examinations, where if it intends to analyze, in future projects, not periodic events of short duration and the dynamics of the biological systems studied, until socket images using hiperpolarizados gases. The techniques implemented in comparison with initially the proposals for Masfield present a difference that is the inexistence of the pulse of RF of inversion and, with this, the time of duration of the implemented sequences are still lesser. But if it does not have to wait very of the quality of the images without the after-processing, a time that this work already is in progress.

Повний текст джерелаShort bowel syndrome (SBS) is a complex disease that occurs after extensive resection of the small intestine leading to malabsorption of nutrients and fluids, a condition that can cause severe watery diarrhea, dehydration and acute weight loss, developing high risk for the appearance of osteometabolic disease. Studies have shown the progress on the physiological interaction of the skeleton with the various systems, including energetic metabolism and the gastrointestinal tract. Peptides originated not only in adipose tissue but also in the intestine such as incretin [GIP (Glucose-dependent insulinotropic polypeptide) and GLP1 (glucagonlike peptide 1) modulate bone remodeling activity. The main objective of the current study was to evaluate the influence of subcutaneous (SAT), visceral (VAT) adipose tissue, intrahepatic lipids (IHL), bone marrow fat adipose tissue (MAT), as well as the influence of GIP, GLP1, and ghrelin on the bone mineral density (BMD) of SBS patients. It is a prospective observational study composed by two experimental groups matched by height, age and sex: a) the control group (CG) (n = 18; 9M,9F) and b) the SBS group which were evaluated in two occasions with a period between analyzes of one year: named SBS0 (n = 14; 7M,7F) and SBS1 (n = 11; 6M,5F). Compared to CG, SBS patients throughout the study had significantly lower BMD and elevated IHL and GIP (p< 0.05). Values of MAT, GLP1 and ghrelin were similar between groups. MAT was negatively and significantly correlated with L3 BMD in the CG (r = -0.6; p< 0.05) and positively correlated, but not significant with L3 BMD in the SBS group throughout the study: SBS0 (r= 0.45; p= 0.13) and SBS1 (r= 0.45; p= 0.17). IHL was negatively and significantly associated with femoral neck BMD (R²= 0.16; p< 0.05) and total hip BMD (R²= 0.27; p< 0.05). The occurrence of osteoporosis is frequent in SBS patients, but MAT is not increased in these patients and had positive correlation with BMD, although not significant. Access to calories seems to positively affect the relationship between MAT and bone mass. IHL appear to negatively affect bone mass in SBS patients.
