See Seminars for further information on all the upcoming seminars. Barney Glaser's now world famous troubleshooting seminars are designed for PhD candidates to trouble shoot exactly their next question with regard to doing their GT dissertation.
The goal is to get candidates closer to finishing the PhD dissertation, by troubleshooting their current GT problem s and listening to other student's current GT problems in an open, supportive and noncompetitive discussion.
Seminars cover the many GT issues candidates face in completing their PhD dissertation. All students will learn from each other, and receive invaluable help.
The book is about the origins and growth of grounded theory GT as developed and written by Barney G.
It is not written to compete or compare with other QDA methods. The competition with other perspectives is up to the reader to write up, if he so desires.
My goal in this paper is to write up the GT perspective clearly and historically to date so it can be used by others in research and the rhetorical wrestle between different perspectives.
As GT spreads throughout the world a clear view of the GT perspective is constantly needed and requested from me by researchers for doing GT and for trying to explain the method to others, particularly supervisors and peer reviewers.
One of the precious properties of classical grounded theory GT is the autonomy it gives the researcher. A response to a cry for help from a novice GT researcher can take away his autonomy It can be a strong answer by a strong senior researcher that undermines the merging theory of the novice.
The novice must be careful not to yield or give away his power of autonomy for a need for help as desperate as he may feel the need. This book deals with this issue of losing and of preserving autonomy and many related issues.
This book deals simply with choosing classic grounded theory CGT as the methodology to use mainly for doing the dissertation.
CGT stands alone as a separate method not as a competitive method in conflict and controversy with all the QDA qualitative data analysis methods jargonized as a type of GT.
This reader provides a myriad of CGT properties to consider in choosing it as the method to use.
There will be no competitive arguments with other methods offered here. It is designed to have CGT chosen on its merits for the user, not better or worse.
It can be pre-ordered by going to. Grounded Theory Review is now an open access journal! Are you undertaking a classic grounded theory study, but have no one to mentor you?
She can connect you with a Grounded Theory Institute Fellow who can offer you tailored support. This anthology brings together a collection of articles on classic grounded theory organized around the concept of mentoring the method.
With 19 contributors, most of whom have studied with Barney Glaser; the book is a wonderful tribute to both the man and the method.
It does a great job of explaining the roots of GT exploring the life, philosophies and influences on Barney Glaser , correcting some misunderstanding about the method, and looking at advances in the method.
It is useful to both the novice and the experienced researcher. He talks about the literature review, grounded theory as a jargon, high impact variables, conceptualization, and more.

DHA increased mean gestational age from Conclusion: DHA supplementation at this level is safe, Prenatal supplementation increased gestation duration, DHA status markers in mother and newborn, birth weight, length, and head circumference.
Supported by 1R01 HD The effects of ruminant trans fatty acids R-TFA have only been studied recently. Similarly, other epidemiological studies also indicated the lack of association between R-TFA intake and cardiovascular risk.
Intervention studies carried out in Canada and France were published at the beginning of the present Century. These data suggested that, at least at usual levels of consumption, there is no association between R-TFA intake and cholesterol-dependant cardiovascular risk factors, but men and women appeared to present different patterns.
To draw definitive conclusion, we conducted a meta-analysis including all the intervention studies in healthy volunteers with at least one experimental group with documented R-TFA intake.
From thirteen studies that met all our selection criteria, we extracted data from one or several groups, yielding to twenty-two observations.
Daily intakes of R-TFA ranged from 0. However, further analysis such as multivariate analysis including confounders would be relevant to confirm these results.
Trepanier, A. Domenichiello, Z. Liu, R. Bazinet University of Toronto, Canada Background: Eicosapentaenoic acid EPA is currently under investigation as a potential treatment for neurological disorders such as bipolar disorder and major depression; even though, in the brain, its function is poorly understood and the levels of EPA are fold lower than docosahexaenoic acid DHA.
Freeliving rats were infused at steady state for 5 minutes via the tail vein and blood samples were collected throughout infusion via jugular vein catheter.
After 5 minutes, rats were subjected to high-energy, headfocused microwave irradiation and brains were collected.
Preliminary results: Radioactivity in the aqueous fraction decreased significantly in MEP-treated brain compared to vehicle controls palmitate: 3.
This was accompanied by a significant increase in total lipid radioactivity of MEP-treated brains as compared to controls palmitate: 1.
Future analysis: Radioactivity in various neutral lipids and phospholipid fractions will be analyzed and the identities of radiolabeled fatty acids will be determined.
Thomas, Iris J. Edwards, Isabelle M. Berquin Departments of Cancer Biology, Biochemistry, Pathology; Wake Forest School of Medicine, USA Phospholipids are crucial components of cellular membranes as well as signaling molecules, with fatty acids at the sn-1 and sn-2 position of the glycerol backbone, and choline, ethanolamine, serine or inositol at the sn-3 position.
AKT is a serine-threonine protein kinase that plays important roles in cell growth, proliferation and apoptosis. It is well documented that AKT activation requires its binding to phosphatidylinositol phosphates PIPs with phosphate groups at positions 3, 4 [i.
PI 3,4 P2] and 3,4,5 [i. PI 3,4,5 P3] on the inositol ring. However, it is unclear whether fatty acids at the sn-1 and sn-2 position can affect the ability of PIPs to activate AKT.
Here we show that dietary polyunsaturated fatty acids PUFA modify phospholipid structure. Our study suggests that dietary fat, through the structural modification of phospholipids, can affect the AKT signaling pathway that is critical in the development of human cancers.
However, the mechanism is not clear. We also studied the correlation between NF-KB signaling and tumor weight in rat mammary tumor. Western blot analysis was performed on whole cells, cytosol and nuclear fractions for the NF-KB signaling protein expression.
Methods: Forty healthy participants were recruited. Pre-supplementation control : A single oral dose of 50 mg of 13C-DHA was given to the participants at breakfast, and its appearance in plasma and betaoxidation was monitored for 28 days.
A supplement 3. Post-supplement: In the last 28 days of the supplementation, a single oral dose of 50 mg of 13C-DHA was given to the participants to follow its metabolism.
Post-supplement, cumulative beta-oxidation was 1. Carlson, Carol L. Cheatham, D. Jill Shaddy, Kathleen M.
Gustafson, Kathleen N. Kannass, Caitlin C. Docosahexaenoic acid DHA , which is found in high concentration in the brain, is specifically thought to affect cognitive function.
At delivery infants were randomly assigned to formulas varying in DHA content: 0. Arachidonic acid was present at 0.
Formulas were fed to 12 mo of age. Results: Seventy of 86 infants followed over the long-term remained in the study through 60 mos. Analyses included Formula and for repeated tests Age.
Further support comes from significant progress in understanding the neurophysiology of DHA at the cellular and lipidomic levels, and in animal models of neurodegenerative disease.
Hence, there is considerable momentum reinforcing the concept of a protective effect of DHA on cognition in the elderly.
Hence, there is a problem in the human studies on AD, i. The focus of this talk will therefore be on discussing two themes that may bridge this disconnect: i human studies of DHA levels in AD brain and plasma, and ii changing DHA homeostasis in the elderly.
The emerging recognition that two important risk factors for AD, i. This abnormality is thought to be a factor for the increased tendency of blood cells of SCD patients to aggregate and adhere to vascular endothelium and subsequently precipitate vas-occlusive crisis and organ damage.
However, sickle cell patients are under oxidative stress and this could be aggravated by supplementation. Plasma alpha-tocopherol vit E , and red blood cell antioxidant enzymes and dimethy acetals marker of plasmalogen status were analysed at baseline and six-month supplementation.
Vit E was assessed in a sub-group of patients after one year. The activities of Se-GPx There was no difference in percent total dimethylacetals in CPG 0.
Plasma vit E concentration increased after one year supplementation Hence, it should be safe to supplement sickle cell patients to help ameliorate membrane abnormality and vaso-occlusive crisis.
We wanted to assess whether supplementation of omega-3 LCPUFAs increases the omega-3 LCPUFA concentration in serum, skeletal muscle and adipose tissue, improves vascular function and morphology and lowers inflammation in obese adolescents.
We also wanted to investigate effects on glucose and insulin homeostasis. Methods: 25 obese adolescents 14 females, 11 males, age The study was performed in a double blind, crossover design with 6 weeks washout period.
Anthropometry, blood pressure measurements and fasting blood samples were obtained before and after each treatment period. Vascular structure and function were measured, intravenous glucose tolerance test IVGTT and euglycemic-hyperinsulinemic clamp were performed, and adipose tissue and skeletal muscle biopsies were obtained after each treatment period.
No difference in total cholesterol, triacylglycerol, HDL cholesterol, anthropometry, blood pressure, pulse wave velocity or vascular structure could be found.
In males, none of these parameters was influenced by omega-3 supplementation. Daily supplementation with omega-3 LCPUFA capsules to obese adolescents increases serum, skeletal muscle and adipose tissue omega-3 LCPUFA concentration, improves vascular function and lowers the degree of inflammation.
It also improves glucose and insulin homeostasis in obese girls without influencing body weight.
Since the identities of leaness-promoting bacteria are unknown, we tested an alternative strategy: genetically engineering gut bacteria to secrete mediators known to reduce fat intake.
N-acyl-phosphatidylethanolamines NAPEs are normally synthesized in the small intestine and their metabolites, N-acyl ethanolamides NAEs , increase satiety and decrease food intake.
We transformed the probiotic E. Four groups of C57BL6 mice 10 mice each received one of four treatments in their drinking water: no additive untreated , 0.
All groups were also fed a high-fat diet ad libitum for 8 weeks. Koalin consumption, a measure of gastric distress in mice, was similar in all four groups.
We then stopped treatment of drinking water while continuing high-fat feeding for 4 additional weeks. Post-treatment body weight gain for mice previously administered pAT-EcN was 1.
These findings suggest that consumption of probiotics engineered to express NAPE may be a useful treatment strategy for obesity. Dietary n-3 polyunsaturated fatty acid regulation of adipokines and inflammatory mediators in adipocyte-macrophage paracrine interactions in vitro De Boer, Anna A; Robinson L.
University of Guelph, Canada In obesity, paracrine interactions between adipocytes and infiltrating macrophages in adipose tissue generate inflammation and related complications.
Similar results were found in the trans-well system, although in all fatty acid groups, adipokine secretion was nearly two-fold lower from the trans-well co-culture, emphasizing the importance of direct adipocyte-macrophage contact in paracrine interactions.
The trans-well co-culture system allowed for isolation of adipocytes to measure mRNA expression of pro-inflammatory mediators.
Overall, these data demonstrate that long-chain n-3 PUFA can decrease pro-inflammatory adipokine secretion and mRNA expression of various pro-inflammatory mediators and thus may provide a beneficial strategy to reduce inflammation in an obese state characterized by macrophage infiltration into adipose tissue.
Ouwehand, J. Research Institute, Faculty of Psychology and Education, VU University Amsterdam, Netherlands; Department of Psychiatry and Neuropsychology, Maastricht University, Netherlands Fish consumption has shown its benefits for cognitive functioning in the elderly or children with disorders e.
Therefore an observational study in Dutch high school students aged years was executed. Fish consumption data, end term grades, scores on the Amsterdam Vocabulary Test, and scores on the Youth Self-Report were collected.
Results revealed that Thus, our findings suggest that irrespective of sex, age, and educational track, the association between fish consumption and cognitive performance and academic achievement in adolescents consists of an inverted U-shape.
Higher fish intake was associated with more advanced vocabulary and higher end term grades. However, eating more fish than the described recommended amount seemed no longer beneficial.
The differences found between the groups e. The difference in z-score between the mg fish group and the highest fish consumption group equals 0.
This difference in fish consumption could therefore account for the difference between passing or failing. Procedure: Two groups of dams were fed during gestation and lactation with either a deficient ALA-palm diet containing minimal ALA level 0.
The present study demonstrates that ALA is a very potent inhibitor of the apoptosis induced by the tumor necrosis factor TNF in cardiomyocytes.
Indeed, after short exposure to TNF, survival cascades are promoted in cardiac cells, while a long-lasting cytokine stimulus causes apoptosis.
ALA pre-treatment inhibits the onset of the apoptosis in cardiomyocytes through a mechanism involving caveolae.
In fact, in the presence of ALA, caveolin-3 expression is enhanced and the internalization of the TNF receptor, located into the caveolae, is inhibited determining the abortion of the apoptotic vs.
Hagel, D. Werner, B. Chiapinelli, N. Afshordel, S. Eckert, D. Juan, N. Bazan Dept. In case of a deficit of antioxidants and antioxidant cellular mechanisms the high turnover of oxygen results in the production of reactive oxygen species and ensuing damage of essential biomolecules.
Those deleterious effects accumulate especially in differentiated tissues like the brain. As a major consequence, perturbations of the energy metabolism including mitochondrial dysfunction culminate in functional deficits.
With the increasing average life span of humans, age-related cognitive disorders such as Alzheimer disease AD are a major health concern in our societies.
Strategies for long-term prevention from mitochondrial dysfunction including sufficient supply of essential nutrients may also delay the onset of age-related neurodegenerative diseases.
Neuroprotective properties of FO were assessed ex vivo after 21 days in dissociated brain cells DBC and isolated mitochondria mito. DHA levels were significantly lower in brains of aged mice and this deficiency was compensated by FO administration.
Our findings provide new mechanisms underlying the neuroprotective actions of polyunsaturated fatty acids and identified FO as promising neutraceutical to delay age-related cerebral alterations.
Supported by: Arbeitskreis Omega-3 e. Forty children aged y were matched in pairs for age, sex and maternal education and randomly assigned to intervention or control treatment.
One group received daily a margarine enriched with either 1. The study had a parallel design and duration of 3 months.
At baseline and end of intervention, fasting blood samples were drawn and analyzed on fatty acid composition of plasma lipids and red blood cell RBC phospholipids and on concentration of blood lipids.
Baseline blood lipid concentrations were on average 0. Results on blood lipid concentration will be presented and discussed.
LCPUFA are rapidly incorporated into the microdomains of the cell membrane lipid rafts where important death and growth receptors and signals are located.
Studies from our laboratory have demonstrated that the incorporation of the DHA and EPA into lipid rafts is associated with reduced epidermal growth factor receptor and increased CD95 Fas in plasma membrane rafts.
These changes were associated with post membrane changes in the signaling pathways and cell growth and apoptosis, thereby providing possible membrane-mediated mechanisms for the effects of n-3 LCPUFA on the survival of human breast cancer cells.
The cell membrane is also the target for doxorubincin DOX or adriamycin one of the drugs of choice for treatment of highly invasive metabolically active breast tumors.
Its metabolism into proand anti-inflammatory eicosanoids e. Other bioactive lipids play key roles during inflammation.
Among them are the endocannabinoids, which consist of a fatty acid linked to a molecule of glycerol or a molecule of ethanolamine. The resulting glyceryl-esters e.
Endocannabinoids are biosynthesized on demand and are hydrolyzed rapidly to fatty acids. While the pharmacological or genetic inhibition of cannabinoid receptors supports an anti-inflammatory role of endocannabinoids, the latter induce pro- and anti-inflammatory effects.
We believe this is related to 1 their metabolism by eicosanoid biosynthetic enzymes; and 2 their hydrolysis into arachidonic acid and the subsequent synthesis of eicosanoids.
The resulting lipidome consists of numerous bioactive lipids with either pro- or anti-inflammatory effects.
Interestingly, while endocannabinoids can serve as a source of arachidonic acid, fatty acid intake modulates endocannabinoid levels in the tissues.
Recent evidence supports this functional link between arachidonic acid and endocannabinoids as they play a key role in the regulation of inflammation.
Key findings regarding the functional link between endocannabinoids and arachidonic acid will be presented.
Fatty acids, lipids and cardiovascular HDL Francis, Gordon University of British Columbia, Canada Levels of plasma high density lipoprotein cholesterol HDL-C correlate generally and directly with protection against coronary heart disease, yet the level of cholesterol itself in HDL particles is frequently a poor predictor of HDL function and protection.
HDL are thought to protect against atherosclerosis for numerous reasons, including removing excess cholesterol from cells and reducing artery wall inflammation.
No lifestyle or therapeutic maneuvers, however, so far raise HDL-C specifically enough to allow this hypothesis to be tested in humans. Clinical trials with niacin to raise HDL-C, among other effects on lipoproteins, have had mixed results, and more definitive trials are ongoing.
Agents that raise HDL-C by inhibiting cholesteryl ester transfer protein are also being investigated for potential benefit. This presentation will review the potential beneficial actions of HDL, other markers of HDL function that may be more informative than HDL-C, and maneuvers to raise HDL that are currently available or under development Linoleic acid and inflammation: evidence based research from clinical studies Fritsche, Kevin; Guy Johnson University of Missouri, USA A systematic review of randomized controlled trials that permitted the assessment of dietary linoleic acid LA on biological markers of chronic inflammation among the healthy non-infant population was conducted.
Fifteen studies eight parallel and seven cross-over met inclusion criteria. None of the studies reported significant findings for a wide variety of inflammatory markers including C-reactive protein, fibrinogen, plasminogen activator inhibitor type 1, cytokines, soluble vascular adhesion molecules or tissue necrosis factor-alpha.
The only significant outcome measures reported for higher LA intakes were greater excretion of prostaglandin E2 and lower excretion of 2,3-dinor-thromboxane B2 in one study 1 and higher excretion of tetranorprostanedioic acid in another.
However, both authors observed that these effects were not an indication of increased inflammation. It is concluded that virtually no evidence is available from randomized, controlled intervention studies among healthy, non-infant humans to show that variations in the level of LA in the diet affects in vivo inflammation in healthy humans.
Recent evidence has called into question this mantra. Confounding influences that occur as a result of variations in the effects of specific saturated fatty acids, replacement by other macronutrients, obesity state and a myriad of lifestyle factors has called the saturated fat hypothesis into question.
An association of saturated fat intake with CVD risk has not been consistently shown in prospective epidemiologic studies.
Clinical trials that replaced saturated fat with n-6 polyunsaturated fat have mostly shown a reduction in CVD events, although several studies showed no effects.
The effectiveness of replacement of saturated fat by monounsaturated fat has been called into question and replacement with a higher carbohydrate intake, notably those with a high glycaemic index, is considered inadvisable due to effects on insulin resistance and obesity.
Recent reviews have highlighted the complications in replacing saturated fat and trans-fatty acids intake with n-6 PUFA linoleic acid in controlled trials showed limited benefit and have suggested that n-3 PUFA may be responsible for the protective association between total PUFA and CVD.
Creating clear guidelines from the epidemiological and clinical trial data has been made increasingly difficult in an environment where total energy intakes have increased with the resulting global increase in obesity in all age groups.
Background: There is uncertainty regarding the efficacy of increasing n-3 long chain polyunsaturated fatty acid LCPUFA intake during pregnancy on reducing the risk of gestational diabetes mellitus GDM and pre-eclampsia PE.
Birth outcomes and prenatal complications were also assessed. Birth weight, length and head circumference z-scores also did not differ between the groups.
Harding, Peter Eck, Peter J. Using a randomized crossover design, 36 hyperlipidemic subjects consumed 3 isoenergetic diets for 28 d enriched in FXCO No change in 13C-DHA was observed between diets.
Optimized rapeseed oil naturally enriched with healthy micronutrients: a relevant nutritional approach to prevent cardiovascular diseases.
INRA, France Rapeseeds are naturally rich in cardioprotective micronutrients but refining leads to substantial losses either by physical removal or by chemical reaction such as isomerisation.
We aimed to investigate the cardioprotective properties of this Optimized oil. In conclusion, reasonable intake of an Optimized rapeseed oil resulting from innovative refining processes and naturally enriched in cardioprotective micronutrients represent a relevant nutritional approach to prevent the risk of cardiovascular diseases by improving the cholesterol profile and reducing LDL oxidation.
Objective: The objective was to evaluate the effect of maternal omega-3 LCPUFA supplementation compared to a placebo in pregnancy on infant and child visual and neurological development.
Human randomised control trials that supplemented the maternal diet with omega-3 LCPUFA during pregnancy or pregnancy and lactation and assessed either visual or neurodevelopment of the offspring were included.
The quality of included trials was assessed with set criteria and results of eligible trials were compared in meta-analyses when possible Results: No clear differences in standardized psychometric test scores were observed between groups.
At no other age was there a difference between the groups in any psychometric measure of cognition although LCPUFA-supplemented infants had better eye and hand coordination MD 6.
Due to a variety of visual development assessments it was not possible to combine outcomes of different studies in a meta-analysis.
Conclusion: The evidence does not conclusively support or refute that omega-3 LCPUFA supplementation in pregnancy improves visual or cognitive development.
V; Rubia, K. Objectives: To investigate: 1. The supplementation ERP study, however, showed no significant effect of fatty acids intervention.
Furthermore, significant relationships were observed between baseline levels of fatty acids and ERP components in both HC and the ADHD groups, suggesting the involvement of fatty acids in the neural activity of brain function.
A century of change in linoleic acid: Endocannabinoids, obesity and addiction Hibbeln, Joseph R. Alvheim National Institute on Alcohol Abuse and Alcoholism, USA Suppressing hyperactive endocannabinoid tone is a critical target for reducing obesity and may reduce other disorders of satiety including alcohol misuse.
Here we posited that excessive dietary intake of linoleic acid LA , the precursor of AA, would induce endocannabinoid hyperactivity and promote obesity.
These animal diets modeled 20th century increases of human LA consumption, changes that closely correlate with increasing prevalence rates of obesity.
Similar patterns of increasing LA consumption and alcohol consumption are evident in the 20th century.
Breast cancer risk biomarkers are associated with dietary intake and tissue content of n-3 polyunsaturated fatty acids PUFA Hidaka, Brandon H.
Harvey, Debra K. Sullivan, Jennifer R. Klemp, Susan E. Carlson, Bruce F. Kimler, Carol J. Methods: Breast tissue was acquired by random periareolar fine needle aspiration from 74 women.
Breast epithelial cells were assessed for cytomorphology and proliferation Ki immunochemistry , which are validated biomarkers for breast cancer risk.
Subjects with atypia consumed less n-3 PUFA: median of 0. A lower ratio of breast TAG nn-6 0. Both lower n-3 intake and tissue content were associated with biomarkers of breast cancer risk.

Management and treatment protocols were determined by red cell lipid analysis of patients blood at Johns Hopkins, Peroxisomal Diseases Laboratory.
Essential fatty acid EFA restoration, EFA balance and removal of oxidized lipids were determined in preparations of oral and intravenous of phosphatidylcholine, glutathione, Subtilisin NAT, eicosapentaenoic acids and methylation factors to decrease whole blood viscosity, increase RBC deformability and initiate reperfusion of post-ischemic conditions resulting from CVAs.
Results: We have previously shown that the use of oral and IV lipids facilitated stabilization of decreased whole blood viscosity and restored microperfusion in several dozen subjects.
This study suggests a correlation of whole blood viscosity and restoration of microcirculation with resolution of post-stroke neurological deficits.
This WBV normalization corresponds to marked clinical improvement in our subjects within the first 3 months of intravenous lipid therapy.
Conclusions: We have documented significant clinical neurological improvement in our subjects along with marked normalization of RBC lipids and hemorheology via laboratory analysis following three months of an oral and intravenous lipid regime.
Why do cancer cells over-express fatty acid synthase? Hopperton, Kathryn E. C Archer, R. P Bazinet University of Toronto, Canada Background: Fatty acid synthase FAS is over-expressed in many human cancer cells even in the presence of pre-formed fatty acids supplied by the medium.
Inhibition of FAS initiates apoptosis in cancer cells and decreases tumorigenesis in vivo, suggesting that FAS plays an essential role to cancer growth and survival.
Hypothesis: Cancer cells utilize endogenously synthesized fatty acids differently than those supplied exogenously, and so have a specific requirement for endogenously synthesized fatty acids.
Total lipids were extracted from the cells and culture medium and radioisotope incorporation into total lipids, cellular lipid classes, phospholipid classes and cholesterol was measured using standard chromatographic techniques and liquid scintillation counting LSC.
HPLC revealed that endogenously synthesized and exogenously supplied fatty acids are primarily palmitate, palmitoleate and stearate.
Analysis of the culture medium revealed that the cancer cells secrete endogenously synthesized fatty acids at 3 fold higher levels than non-cancer cells.
Comparison of cancer and non-cancer cells revealed that cancer cells esterify proportionately less fatty acid to phospholipid and produce over 2 fold more choline glycerol phospholipid than non-cancer cells.
Conclusion: These results suggests that FAS over-expression does not fulfill a requirement for endogenously synthesized fatty acids in cancer cells as these fatty acids are not used for unique functions within the cell.
In addition, a portion of endogenously synthesized fatty acids are excreted, suggesting that they are produced at higher levels than needed to support proliferation.
Chen, Gonzalo M. Rivera, David N. McMurray,Robert S. N-3 polyunsaturated fatty acids PUFA [e. We have previously shown that n-3 PUFA attenuate events critical for T cell activation, including localization of F-actin to the immunological synapse IS.
Since the second messenger phosphatidylinositol- 4,5 -bisphosphate PI 4,5 P2 resides in membrane lipid raft domains and DHA can alter the size of rafts, we hypothesized that PI 4,5 P2 and downstream F-actin remodeling are perturbed by the incorporation of n-3 PUFA into the plasma membrane, thereby suppressing T cell activation.
Impact of human milk and structured lipids on lipoprotein lipids in infants Innis, Sheila M University of British Columbia, Canada The mammary gland has unusual pathways of lipid synthesis that result in truncation of fatty acid synthesis at a carbon chain length of 14 or lower, and uptake of palmitic acid from maternal plasma to maintain a relative proportion of in human milk fatty acids, regardless of the maternal diet.
Triglyceride TG synthesis is also unusual, and involves preferential positioning of at the sn-2 centre carbon of the TG glycerol backbone, with n-9, n-6,n-3 and medium chain fatty acids directed towards the TG glycerol sn-1,3 positions.
Much of the interest in milk TG structures has focused on intraluminal events. Plasma lipoprotein lipids were compared between infants randomized to be fed formula containing structured TG enriched in 2palmitate or from palm olein, and to breast-fed infants at 60 and days of age.
Parallel studies enabling access to tissue lipids were done in piglets fed similar formula. The chylomicron TG of breastfed infants and infants fed formula with snpalmitate showed retention of sn-2 palmitate TG species.
Higher , but lower n-9 and n-6 in plasma monoglycerides of breast-fed infants suggests the milk TG structure may influence tissue fatty acid delivery, with preferential delivery of unsaturated fatty acids to extra-hepatic tissues, with retention of saturated monoglyceride products of lipoprotein lipase.
The TG structure and fatty acid composition also impacted the liver TAG and cholesterol, and tissue fatty acids in animals. The analyses of lipoprotein lipid, monoglyceride and fatty acids in plasma indicates that human milk TAG may be specifically organized for targeted delivery of not only which but how fatty acids are delivered to developing infant tissues.
In recent years, non-fasting triacylglycerol TAG concentrations have emerged as a clinically significant cardiovascular disease CVD risk factor, with hazard ratios of in the highest versus the lowest levels of non-fasting TAG.
Given the strength of these associations are comparable to those of low density lipoprotein cholesterol an established CVD risk factor ; there is considerable interest in understanding the independence of the association, and causality of TAG in CVD.
The postprandial TAG response has been shown to be highly variable between individuals, with the apolipoprotein APO E epsilon genotype likely to be an important genetic determinant as a result of the significant role apoE plays in lipoprotein metabolism.
However, the majority of information regarding the effects of dietary fats on lipid levels in this genotype group has been derived from studies performed in the fasting state.
Since both the amount and type of fat given in a meal has been shown to influence the magnitude and duration of the postprandial lipaemic response, little is known about the independent and interactive impact of APOE genotype.
An overview of the relationship between non-fasting TAG, dietary fat and APOE genotype will be presented; together with recent findings from our group which suggest that dietary fat manipulation may be a more important modulator of the subsequent postprandial TAG response than APOE genotype.
Ruminant trans vaccenic acid decreases fasting and post-prandial hypertriglyceridemia by reducing both hepatic and intestinal TG secretion and associated genes in a rat model of the metabolic syndrome Jacome-Sosa, Miriam M.
Both fasting and non-fasting post-prandial hypertriglyceridemia are risk factors for cardiovascular disease CVD and VA has been shown to decrease fasting hypertriglyceridemia in several pre-clinical animal models.
However, the mechanistic action by which VA exerts its hypotriglyceridemic benefits remains unclear. The objective of this study was i to evaluate the effects of VA on both intestinal fed state and hepatic fasting state TG secretion and ii to profile intestinal and hepatic gene expression using the JCR:LA-cp, a rat model of the Metabolic Syndrome MetS.
Hepatic TG secretion was assessed during fasting conditions whilst intestinal TG secretion was assessed after an oral gavage of [3H] triolein in olive oil following lipoprotein lipase inhibition.
Gene expression data suggests opposing transcriptional control in the liver and intestine as a consequence of VA supplementation.
We propose that VA supplementation may contribute to improving fasting and post-prandial hypertriglyceridemia during conditions of MetS and reduce CVD risk.
Epidemiologic studies on the intake of ruminant trans fatty acids and the risk of CVD Jakobsen, Marianne Uhre Department of Public Health, Aarhus University, Denmark Observational epidemiologic studies have shown a higher risk of coronary heart disease CHD to be associated with the intake of trans fatty acids Mozaffarian et al.
Trans fatty acids arise either from industrial hydrogenation of vegetable oils, or from hydrogenation of unsaturated fatty acids in the rumens of ruminants.
As a result of biohydrogenation, meats and dairy products from cows, sheep, and other ruminants contain trans fatty acids. The sources of industrially produced trans fatty acids are fast foods, bakery products, package snack foods, margarines, and crackers.
Overall, the evidence from observational studies suggests that higher CHD risk is related to the intake of trans fatty acids from industrial sources rather than trans fatty acids from ruminant sources Mozaffarian et al.
Observational studies on the intake of trans fatty acids from ruminant sources and the risk of CHD were reviewed. The association between the intake of trans fatty acids from ruminant sources and the risk of CHD has been investigated in several observational studies.
Among the case-control and follow-up studies, one study Pietinen et al. In a cross-sectional study Bolton-Smith et al.
In summary, observational studies suggest that the intake of trans fatty acids from ruminant sources is not associated with the risk of CHD within the range of intake in the general population.
However, these data do not exclude the possibility that higher intakes than the amounts actually consumed could have adverse effects.
Red blood cell omega-3 fatty acid levels and neurocognitive performance in deployed U. Methods: Servicemembers with mild to moderate depression by the Patient Health Questionnarie-9 from two US military camps were invited to participate in this study.
A battery of validated psychosocial Pittsburgh Sleep Quality Index, and Zung Depression, Zung Anxiety, Espworth Sleepiness, and Combat Experiences scales and computerized neurocognitive tests were completed by each participant.
A drop of blood was also collected on an antioxidant-treated filter paper card and sent for HS-Omega-3 Index analysis. Conclusion: Optimal neurocognitive performance is essential during deployment.
Our finding that EF and CF were positively related to HS-Omega-3 Index suggests that improving omega-3 status through an increase in omega-3 intake may improve neurocognitive performance and confer an element of resilience to poor sleep.
Monounsaturated and high linolenic acid oils, plasma lipids and fatty acid metabolism Jones, Peter J. Endpoint measures revealed reductions in serum lipid concentrations, including 7.
Consumption of the dietary oils failed to alter whole-body fat oxidation or energy expenditure, nor lead to any changes in body composition.
No differences in plasma 13C-DHA enrichment were observed across diets. Our previous findings revealed a link between toxic exposures, a characteristic accumulation of very long chain fatty acids VLCFAs in the form of lipid rafts or ceramides, and the development of cell membrane derangement resulting in dysfunction.
In our current study we have captured visual images of toxins on the cell surface which have caused disturbances in cellular phospholipid structure and mitochondria of individual subjects, and have linked the impact of the DNA adducts toxins altering gene expression to aberrations in lipid metabolism, cellular dysfunction and alteration of the structure of phospholipids in the cell membrane characteristic to the presenting diagnosis and symptoms.
While further work remains and the microscopic significant of these correlations needs further clarification, initial biochemical and clinical results appear promising.
Radial maie study in rats confirmed neuroprotective and memory boosting effects of krill oil. In this study we expanded the work in human to study if the krill oil adminstration will improve mental perfomance.
Using double blind, randomized, placebo control trial, 45 adult Japanese men 62 - 75 years were divided into 3 groups; fish oil group, krill oil group and palcebo group.
The subjects were given 2 g of the test substance in capsule form for 12 weeks. At the end of 12 week intervention, the subjects were subjected to brain functional neuroimaging to measure 1 oxyhemoglobin concentration by near infrared spectroscopy NIRS when the subjects performed a memory task and a calcualtion task and 2 brain event related potential P None of the interventions showed any side effects.
Krill oil treatment increased the oxyhemoglobin concentration in anterior and temporal areas of the brain following memory and calculation tasks.
The increase in oxyhemoglobin concentration was much higher with krill oil than with fish oil or placebo treatment.
Depending on the task, the different areas of the brain showed increase in oxyhemoglobin concentrations, suggesting different parts of brain are involved in different activities.
P measurement is an index of overall activity of brain. The amplitudes of P wave is related to cognitive funciton while the latency of the wave is associated with the speed of information processing.
Kril oil treatment reduced the latency, indicating it improved the speed of information processing in adult males.
Serum fatty acid composition was measured by gas-liquid chromatography. Berthiaume Department of Pathology and Laboratory Medicine, University of British Columbia, Canada; Department of Cell Biology, University of Alberta, Canada Palmitoylation or S-acylation of proteins is a reversible and versatile post-translational protein modification PTM , which involves a covalent binding of a fatty acid mostly palmitic acid to free thiols of cysteine residues.
This PTM plays important functional roles in cellular processes, such as membrane anchoring of protein complexes , signaling, trafficking and protein-protein interactions.
Measurement of palmitoylation is challenging due to a lack commercially available standards, poor longterm stability of the palmitic thioester bond and lack of adequate enrichment- or sensitive enough methods for detection.
In recent collaborative efforts, we have shown that direct mass spectrometric analysis of S-acylated peptides labeled with palmitate or palmitate analogues, obtained through enzymatic digestion of palmitoylated proteins is readily possible.
Furthermore, specific release of palmitate from S-acylated sites and relabeling with stable-isotope labeled alkylating agents, such as for example deuterated Nethylmaleimide, allows for quantitative comparisons of palmitoylation extent between samples of different origin, e.
Here, we will present further examples and an overview of our new approaches towards characterisation and measurement of S-acylated proteins, employing advanced mass spectrometry.
A number of cross-sectional human studies reported negative associations between IR and tissue concentrations of n-3 PUFA, but results from human intervention studies have varied.
Besides the changes in glucocentric markers of IR, an equally important aspect of IR is the effects of insulin on lipid metabolism lipocentric markers.
DHA supplementation increased fasting plasma glucose concentration by 4. It also did not alter other indices of IR based on fasting insulin and HOMA-IR or postprandial insulin and glucose concentrations areas under curves for insulin and glucose, Matsuda index.
None of the variables changed in the placebo group. Our results suggest that lipocentric markers of IR are more responsive to DHA supplementation than the glucocentric markers.
Future studies with DHA in pre-diabetic subjects and direct measures of insulin sensitivity are needed. As DHA is readily incorporated into the phospholipids in neuronal membranes, DHA can influence not only chemical and physical properties of cell membranes but also membrane related signaling events involved in neuronal survival, proliferation and differentiation.
Our studies have indicated that DHA supplementation increases phosphatidylserine PS accumulation and inhibits neuronal cell death under challenged conditions, supporting a notion that DHA is an important neuro-protective agent.
We also found that DHA released from the membrane is metabolized to a potent synaptogenic agent, synaptamide N-docosahexaenoylethanolamide , promoting neurite growth, synaptogenesis and glutamatergic synaptic function in developing neurons as well as neuronal differentiation of neural stem cells NSCs.
Molecular and signaling mechanisms underlying DHA-mediated beneficial effects will be discussed in the context of neuroprotection, particularly under challenged conditions such as in brain injury.
Besides composition, fat quality also encompasses physical properties of lipid droplets. Compared to current infant formula, lipid globules in human milk are up to 10 times larger and coated by a phospholipid membrane.
Weight, adipocyte number, size distribution and gene expression were analysed in white adipose tissue WAT depots. Lean body mass, food intake and adipocyte number were similar in all groups.
The expression of Pref1 preadipocyte marker remained unaffected by any of the diets, illustrating comparable preadipocyte numbers.
A resulting DHA depletion has been demonstrated in PKU children and may account for detectable subtle neurological deficits that are not explained by variation in plasma phenylalanine concentrations.
DHA supplementation resulted in significantly faster visual evoked potential latencies, indicating more rapid central nervous system information processing.
In addition, DHA significantly improved outcomes in a standardized test of motor function and coordination.
No changes over time were seen in aged matched healthy controls. Since the PKU children had a good supply of the omega-3 precursor alpha-linolenic acid, these observations lead us to conclude that endogenous conversion of alphalinolenic acid is not sufficient to provide adequate amounts of DHA that support optimal function.
Since early treated PKU children are healthy, with normal fatty acid turnover, these data may indicate a need to supply some DHA to children in general.
In an ongoing multicentric study funded by the European Commission, we aim at establishing quantitative dose response between DHA supply and functional outcomes that should help defining quantitative DHA requirements in children.
Polyunsaturated fatty acids and child health: diet or genes? In the last few years, genetic association studies demonstrated that in addition to nutritional inatkes, the genetic background is highly important for PUFA composition of human blood and tissue lipids.
Recent gene-nutrition interaction studies suggest that these polymorphisms modulate the effect of dietary fatty acid intake on complex phenotypes such as cognitive outcomes and asthma risk in children.
These first results may provide the basis for future, more specific intake recommendations to achieve optimal health benefits for all children.
We present results from those recent gene-nutrition interaction studies, discuss the implications for future observational and intervention studies as well as for child health, and provide suggestions as to how this association might translate into clinical practice in the future.
Complex etiology of metabolic syndrome implies the need of treatments, which are based on multiple mechanisms of action.
Development of the syndrome could be delayed by lifestyle modifications, while both dietary and pharmacological interventions are required for the therapy.
Naturally occurring n-3 long-chain PUFA, namely eicosapentaenoic and docosahexaenoic acids Omega-3 , exert pronounced anti-inflammatory effects, act as hypolipidaemics, reduce cardiac events and may decrease the progression of atherosclerosis.
However, Omega-3 fail to improve glycaemic control in diabetic patients. Experiments in mice fed high-fat diet revealed that Omega-3 could prevent development of obesity and hepatic steatosis, while modulating liver, adipose tissue, intestine and muscle metabolism.
Importantly, Omega-3 could augment beneficial effects of other treatments. Thus, i a combination treatment using Omega-3 and a mild calorie restriction efficiently reduced body fat accumulation, while inducing a metabolic switch toward lipid catabolism in adipose tissue; and ii a combination with anti-diabetic drugs thiazolidinediones exerted additive effects in the amelioration of dyslipidaemia and insulin resistance, while preserving muscle insulin sensitivity and metabolic flexibility, and reverting insulin resistance.
Both combination treatments strongly suppressed low-grade inflammation of adipose tissue. Combination treatment using Omega-3 and a low dose of rosiglitazone reduced obesity.
These results are relevant for the prevention and therapy of obesity and its comorbiditiesatment Effect of pomegranate seed oil on the lipid matabolism in Wistar rat Kostogrys, Renata B.
CLnA has been found abundantly in some seed oils, such as Pomegranate seed oil cis9,trans,cis; C The objective of this study was to evaluate the effect of Pomegranate seed oil as a source of CLnA compared to CLA cis-9,trans on lipid metabolism in Wistar rats.
Twenty four Wistar rats were randomly assigned to four experimental groups and fed for the next four weeks.
The experimental treatments had no effect on plasma TC in rats. Additionally, Flaxseed oil significantly increased HDL cholesterol level compared to Control group 1.
Additionally, the fatty acid composition in rats fed Flaxseed oil and Pomegranate seed oil was significantly changed. In the same line, stearoyl coenzyme A desaturase SCD-1 index was changed.
In rats fed Pomegranate seed oil liver's FAS gene expression tended to decreased. In conclusion, Pomegranate seed oil improved the lipid metabolism more effectively than CLA in laboratory rats.
Department of Nutritional Sciences, Penn State University, USA Epidemiologic studies consistently demonstrate a beneficial association of increased nut and peanut consumption with coronary heart disease and sudden cardiac death.
In addition, nut consumption is inversely associated with hypertension, type 2 diabetes and metabolic syndrome. In addition, nut consumers had fewer criteria for metabolic syndrome.
C-reactive protein also was lower in nut consumers. Numerous clinical studies have provided insight about the underlying mechanisms that account for the health benefits of nuts.
Plasma triglycerides decreased in hypertriglyceridemic individuals. In addition, there is evidence that postprandial walnut consumption may enhance HDL particle functionality and promote reverse cholesterol transport.
With respect to body weight, potential explanatory mechanisms include satiety value of nuts, induction of energy expenditure and inefficient energy absorption.
Animal studies have reported beneficial effects of walnuts on reduction in breast and colorectal cancer, as well as cognitive function.
In addition to the favorable fatty acid profile of nuts and peanuts, other bioactive compounds that explain their health benefits include: macronutrients including plant protein and fiber; micronutrients including potassium, calcium, magnesium, and tocopherols; and phytochemicals such as phytosterols, phenolic compounds, resveratrol, and arginine.
Introduction: The effect of parenteral n-3 fatty acids in critically ill infants, who are at risk of infection, is not widely studied.
This study investigated the effects of parenteral fish oil on plasma lymphocyte and procalcitonin concentrations. Parenteral nutrition was administered continuously for 3 days pre-operatively and 10 days post operatively.
Pediatric risk of mortality PRISM scores were recorded on admission to the pediatric intensive care unit. This observation suggests that an n-3 lipid emulsion containing n:3 and n:3 may suppress the inflammatory response induced by cardiopulmonary bypass and surgery, and therefore may be beneficial to critically ill infants undergoing heart surgery.
