This book was released on 2010 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metabolic syndrome is characterized by obesity, insulin resistance, hypertension and dyslipidemia. It has also been suggested that hepatic steatosis and inflammation should be added to the classical components of the metabolic syndrome. Previous research on obesity and insulin resistance has examined the effects of many different fats and oils, however, the effects of canola oil on metabolic syndrome parameters have yet to be investigated. It is hypothesized that in a diet induced obese (DIO) rodent model, the combination of canola and flax oils will reduce the severity of metabolic syndrome parameters and favorably alter hepatic phospholipid (PL) and triacylglycerol fatty acid composition. The objective of the study was to investigate the biological effects of a 12 week dietary intervention with high fat diets based on various vegetable oils (high oleic canola, canola, canola/flax (3:1; C/F), safflower and soybean) and lard in 6 week old obese prone rats with regards to obesity, insulin resistance, lipidemia, hypertension, inflammation, hepatic steatosis, hepatic fatty acid composition and markers of hepatic fatty acid oxidation and synthesis. Overall the C/F diet attenuated more of the components of the metabolic syndrome, including obesity, glycemia, lipidemia, inflammation and hepatic steatosis, than the other high fat diets in DIO rats. However, each of the dietary treatments attenuated various components of the metabolic syndrome suggesting that all dietary fats and oils have their role in the prevention of different components of the metabolic syndrome. Additionally, the C/F diet led to increased eicosapentaenoic acid and docosahexaenoic acid concentrations in hepatic PL suggesting that [alpha]-linolenic acid can be efficiently converted to its very long chain derivatives in DIO rats. Thus, the addition of flax oil to conventional canola oil, in the C/F diet, appeared to enhance the beneficial effects of canola oil on metabolic syndrome parameters.

This book was released on 2011 with total page 974 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian adults consume ~6% above the recommended intake of saturated fat and less than half the recommended daily amount of n-3 polyunsaturated fatty acids (PUFA). There is some evidence that the type and proportion of dietary fat consumed may influence the development of the obese phenotype and associated metabolic complications. Epidemiological studies indicate that a saturated fat-rich diet (HF-S) is deleterious, whilst consuming n-3 PUFAs is beneficial to metabolic health. Saturated fats have a greater propensity to enter storage in adipose tissue and ectopic stores, as opposed to being oxidised. This is deleterious as ectopic fat deposition in skeletal muscle and liver are strongly associated with insulin resistance. In contrast, diets rich in n-3 PUFA limit adipose tissue hypertrophy, reduce ectopic fat and prevent high fat diet (HFD)-induced insulin resistance in rats. However, the mechanism by which n-3 PUFA enrichment of a HF-S diet (HF-n-3) prevents ectopic fat deposition in muscle and liver is unclear; though pathways of fatty acid uptake, storage and oxidation may be implicated. Furthermore, in skeletal muscle a functional shift in fibre type may be implicated, as increased muscle n-3 PUFA content is associated with an increased proportion of oxidative fibres. The studies in this thesis therefore aimed to determine: (I) the effect of HFD fatty acid composition on metabolic profile, adipose tissue distribution, and muscle fibre type composition of male and female mice; (II) if HF-n-3 feeding influenced the mRNA content of 27 key genes that regulate the uptake (FAT/CD36, FABPpm, FATP), synthesis and storage (SREBF, INSIG, SCD, ACC, DGAT, HSL) and utilisation (PDK, PPAR, PGC1, AMPK, ACC, CPT1, UCP) of fatty acids and metabolism of glucose (HK, PFK, GYS) in the glycolytic extensor digitorum longus muscle, oxidative soleus muscle and liver of male and female mice. To assess these aims mice were fed either a control diet (16% energy from fat) or one of two HFDs (60% energy from fat), a HF-S or HF-n-3 (7.5% saturated fat replaced with n-3 PUFA) diet. I investigated the hypothesis that HF-n-3 feeding prevents ectopic fat deposition through enhanced uptake and utilisation, and reduced storage, of fatty acids. Despite similarly increased body weight with both HFDs, mesenteric fat mass decreased and brown fat increased with HF-n-3 feeding compared to HF-S feeding. HF-S feeding increased muscle and liver fat content; this was ameliorated by HF-n-3. As hypothesised, HF-n-3 feeding may ameliorate intramyocellular and intrahepatic fat accumulation through an altered pattern of fatty acid metabolism gene expression in those tissues, specifically through the concurrent activation of pathways regulating fatty acid transport and utilisation, whilst limiting pathways that promote fatty acid storage and lipogenesis. Muscle fibre type composition was unchanged with diet, although HF-n-3 feeding increased muscle oxidative capacity. HF-S mice exhibited increased plasma insulin and glucose metabolism was influenced by HF-n-3 feeding in a tissue-specific manner. These studies highlight the importance of gender and in skeletal muscle, muscle fibre type, to the overall characteristics, profile of gene expression and ultimate function of the skeletal muscle and liver.

Abstract: Abstract of thesis entitled The Effects of Ageing and High-Fat Diet on the Gene Expression of Adrenomedullin and its Receptor Components in Rat Skeletal Muscles and Adipose Tissues Submitted by Hei Man Chow for the Degree of Master of Philosophy at the University of Hong Kong In August 2007 Metabolic syndrome is characterized by obesity, hypertension, insulin resistance, dyslipidemia and atherogenesis. Insulin resistance is a state in which a given concentration of insulin produces a sub-optimal biological effect in target tissues of skeletal muscle, adipose tissue and liver. Despite reports about the presence of adrenomedullin (AM) in skeletal muscles and adipose tissues, and the effect of high-fat diet induced obesity on its expression, details of the effects of ageing on AM levels in rat have not been reported. Here, the effects of ageing and high-fat diet on the gene expression of AM and its receptor component proteins, the metabolic effects of AM on skeletal and adipose tissue and the regulation of AM gene expression by glucose and insulin are reported. Both ageing and high-fat diet reduce the gene expression of preproAM in the skeletal muscle and adipose tissue. For the gene expression of receptor component proteins in the skeletal muscle, calcitonin receptor-like receptor (CRLR) was reduced by both, but the receptor activity modifying protein (RAMP) 2 was only decreased on ageing. In the adipose tissue, significant reductions of gene expression were observed in all the receptor component proteins (CRLR, RAMP1, RAMP2 and RAMP3) from the ageing study only. Moreover, immunoreactive (ir-) AM peptide contents were decreased by the ageing and high-fat diet in both skeletal muscle and adipose tissue. All these changes might suggest a reduction of AM level and functions. Obesity is characterized by hyperinsulinemia and hyperglycemia. Ageing is also characterized by hyperinsulinemia. Hyperinsulinemia and hyperglycemia might affect the gene expression of AM in skeletal muscle and adipose tissue. We found a decrease in AM gene expression by insulin in vitro in the skeletal muscle, similar to the adipose tissue, as reported previously. However, glucose did not lead to any significant changes. These suggest the AM gene expression in the skeletal muscle and adipose tissue is under transcription control of insulin but not glucose. The changes in AM gene expression suggested that AM might play roles in the regulation of fuel metabolism in the skeletal muscle and adipose tissue. We extended the studies to the effects of AM on insulin-stimulated glucose uptake, and found that was inhibited by AM in both skeletal muscle and adipose tissue. Such effects were reversed by a specific AM blocker, hAM(22-52); as well as a specific protein kinase A blocker, H89. Lipolysis in adipose tissue was enhanced with AM. These findings showed the increase in AM might be a possible cause to the insulin resistance.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this monograph is to present readers with a comprehensive and cutting edge description of neurochemical effects of diet (beneficial and harmful effects) in normal human brain and to discuss how present day diet promotes pathogenesis of stroke, AD, PD, and depression in a manner that is useful not only to students and teachers but also to researchers, dietitians, nutritionists and physicians. A diet in sufficient amount and appropriate macronutrients is essential for optimal health of human body tissues. In brain, over-nutrition, particularly with high-calorie diet, not only alters cellular homeostasis, but also results in changes in the intensity of signal transduction processes in reward centers of the brain resulting in food addiction. Over-nutrition produces detrimental effects on human health in general and brain health in particular because it chronically increases the systemic and brain inflammation and oxidative stress along with induction of insulin resistance and leptin resistance in the brain as well as visceral organs. Onset of chronic inflammation and oxidative stress not only leads to obesity and heart disease, but also promotes type II diabetes and metabolic syndrome, which are risk factors for both acute neural trauma (stroke) and chronic age-related neurodegenerative and neuropsychological disorders, such as Alzheimer disease (AD), Parkinson disease (PD) and depression.
