The Tracking Of Dietary Intakes Of Children And Adolescents In Sweden Over Six Years: The European Youth Heart Study, Emma Patterson, Julia Wärnberg Julia Wärnberg, John Kearney, Michael Sjostrom

Articles

The stability of dietary habits through various life-stages is not well understood. A better understanding of the tracking of diet over time could have implications for health promotion as well as for the planning of nutritional epidemiology studies. We examined the stability of dietary intakes of children and adolescents over six years. As part of the European Youth Heart Study, in 1998-9, a 24-h dietary recall was performed on over one thousand 9- and 15-year-olds in Sweden. In 2004-5, 40% returned to the follow-up study. These 452 subjects (273 15- and 179 21-year-olds) were assigned to age- and gender-specific tertiles …

Editorial: Nutrition Research Reviews, Katherine Younger

Articles

Cognitive performance in children and whether this can be improved by nutritional means is an area of investigation fraught with experimental challenges, making it difficult to draw useful conclusions. Hoyland et al. (1) have here provided a much-needed systematic review of the evidence on the specific question of the effects of breakfast on children’s cognitive performance and, unsurprisingly, have concluded that the effects are generally positive, most clearly shown for memory and attention tasks and most easily demonstrated in nutritionally vulnerable children. However, the benefits of food before schoolwork are not necessarily purely, or even mostly, physiological; they could be …

Editorial: Nutrition Research Reviews, Katherine Younger

Articles

The diverse nature of the reviews included in this issue of Nutrition Research Reviews highlights a problem that is becoming increasingly acute for journal editors, namely that of finding suitable reviewers (especially for the more esoteric manuscripts) who are prepared to devote some of their time and expertise to this crucial task. Peer-review underpins the whole ethos of scientific journal publishing as we currently know it. Without it, readers have little guarantee that the published material is credible, which in turn casts the authors in a dubious light, and with them the editors and publishers of the journals; the whole …

Inactivation Of Escherichia Coli In Orange Juice Using Ozone, Sonal Patil, Paula Bourke, Jesus Maria Frias, Brijesh Tiwari, Patrick J. Cullen

Articles

This research investigated the efficacy of gaseous ozone for the inactivation of Escherichia coli ATCC 25922 and NCTC 12900 strains in orange juice. Orange juice inoculated with E. coli (10⁶ CFU mL^-1) as a challenge microorganism was treated with ozone at 75-78µg mL^-1 for different time periods (0-18 min). The efficacy of ozone for inactivation of both strains of E. coli was evaluated as a function of different juice types: model orange juice, fresh unfiltered juice, juice without pulp, and juice filtered through 500mm or 1mm sieves. Fast inactivation rates for total reduction of E. coli …

Second-Hand Smoke Exposure In Cars And Respiratory Health Effects In Children, Patrick J. Goodman, Z. Kabir, Luke Clancy, P.J. Manning, J. Holohan, S. Keogan

Articles

We examined potential associations of ever asthma, and symptoms of wheeze (past 12 months), hay fever, eczema and bronchitis (cough with phlegm) among school children exposed to second-hand smoke (SHS) in cars, using a modified Irish International Study of Asthma and Allergies in Childhood (ISAAC) protocol. 2,809 children of 13–14 yrs old and who selected randomly from post-primary schools throughout Ireland completed the 2007 ISAAC self-administered questionnaire. Adjusted OR (adjusted for sex, active smoking status of children interviewed and their SHS exposure at home) were estimated for the associations studied, using multivariable logistic regression techniques. Overall, 14.8% (13.9% in young …

Advertising Connoisseurs: Children's Active Engagement With And Enjoyment Of Television Advertising, Margaret-Anne Lawlor

Articles

The literature pertaining to advertising and children has tended to focus on how advertising affects children at cognitive, attitudinal and behavioural levels. A key element of the debate has been the extent to which children understand advertising as a mode of commercial communication, and the potential associated outcomes such as advertising scepticism and pester power. This paper adopts a different approach by exploring the extent to which television advertising can constitute a resource for a child's own use and enjoyment. As part of an interpretive study of a group of Irish children aged seven to nine years which explores their …

Dissertation Citations In Organismal Biology At Southern Illinois University At Carbondale: Implications For Collection Development, Jonathan Nabe, Andrea Imre

Articles

We report on a citation analysis of PhD dissertations in Plant Biology and Zoology at Southern Illinois University Carbondale, undertaken to test the common assumption that scientists favor current research to such an extent that journal backfiles can be de-emphasized in academic library collections. Results demonstrate otherwise. The study is reproducible for any institution, and can help to evaluate 1) the value of electronic journal backfiles and 2) the need to maintain print backfiles.

The Professional Ethics Of Billing And Collections, Mark A. Hall, Carl E. Schneider

Articles

Medicine is a Profession on which physicians rely for their livelihood and patients for their lives. If physicians do not charge for services, they cannot survive. If patients cannot afford those services, they cannot survive. No wonder many physicians have long agreed that fees are “one of the most difficult problems . . . between patient and physician.” For years comprehensive insurance subdued this problem, but currently widespread underinsurance and consumer-directed health care are reviving it. Even as the ranks of the uninsured continue to increase,the latest hope for controlling medical costs requires insured patients to pay for much more …

Green Tea Extract As A Natural Antioxidant To Extend The Shelf-Life Of Fresh-Cut Lettuce, Catherine Barry-Ryan, Ana Belen Martin-Diana, Daniel Rico

Articles

Green tea extract (GT) was evaluated as a preservative treatment for fresh-cut lettuce. Different quality markers, e.g. respiration, browning, ascorbic acid and carotenoid content were evaluated. GT concentration (0.25, 0.5 and 1 g 100 mL− 1) and temperature (20 °C and 50 °C) were tested. Optimal GT treatment (0.25 g 100 mL− 1 at 20 °C) was compared with chlorine (120 ppm at 20 °C). High GT concentrations (0.5 g 100 mL− 1 and 1.0 g 100 mL− 1) maintained better prevent ascorbic acid and carotenoid loss than 0.25 g 100 mL− 1 GT and chlorine. GT increased browning of …

The Vast Injustice Perpetuated By State And Local Tax Policy, Susan Pace Hamill

Articles

State and local tax policy is one of the most important areas of public policy affecting the lives of the most powerless and vulnerable segments of the population children from low income families Focusing on the funding of primary and secondary education especially in high poverty school districts and the scheme for allocating the tax burden this article empirically proves that all fifty states have unjust state and local tax policy with thirtyone states inflicting an extreme level of injustice on poor children and their families This article argues that the people in most states as well as their political …

Efficient Mining Of Heterogeneous Star-Structured Data, Manjeet Rege, Qi Yu

Articles

Many of the real world clustering problems arising in data mining applications are heterogeneous in nature. Heterogeneous co-clustering involves simultaneous clustering of objects of two or more data types. While pairwise co-clustering of two data types has been well studied in the literature, research on high-order heterogeneous co-clustering is still limited. In this paper, we propose a graph theoretical framework for addressing star- structured co-clustering problems in which a central data type is connected to all the other data types. Partitioning this graph leads to co-clustering of all the data types under the constraints of the star-structure. Although, graph partitioning …

Session 1: Public Health Nutrition Breast-Feeding Practices In Ireland, Roslyn Tarrant, John Kearney

Articles

Breast-feeding is the superior infant feeding method from birth, with research consistently demonstrating its numerous short- and long-term health benefits for both mother and infant. As a global recommendation the WHO advises that mothers should exclusively breast-feed for the first 6-months of life, thus delaying the introduction of solids during this time. Historically, Irish breast-feeding initiation rates have remained strikingly low in comparison with international data and there has been little improvement in breast-feeding duration rates. There is wide geographical variation in terms of breast-feeding initiation both internationally and in Ireland. Some of these differences in breast-feeding rates may be …

Novel Functions Of Acyl-Coa Thioesterases And Acyltransferases As Auxiliary Enzymes In Peroxisomal Lipid Metabolism., Mary Hunt, Stefan Alexson

Articles

Peroxisomes are single membrane bound organelles present in almost all eukaryotic cells, and to date have been shown to contain approximately 60 identified enzymes involved in various metabolic pathways, including the oxidation of a variety of lipids. These lipids include very long-chain fatty acids, methyl branched fatty acids, prostaglandins, bile acid precursors, and xenobiotics that are either β-oxidized or α-oxidized in peroxisomes. The recent identification of several acyl-CoA thioesterases and acyltransferases in peroxisomes has revealed their various functions in acting as auxiliary enzymes in α- and β-oxidation in this organelle. To date, 9 functional acyl-CoA thioesterases and acyltransferases have been …

We are all familiar with the dietary guideline exhorting us to eat so many portions of oily fish per week in order to boost our intakes of n-3 long-chain PUFA, but it is perhaps not so widely realised that the fish must themselves be provided with dietary n-3 long-chain PUFA or, possibly, their precursors (though, as in humans, the ability of carnivorous fish to elongate and desaturate n-3 PUFA appears to be limited).

Can Glucksberg Survive Lawrence? Another Look At The End Of Life And Personal Autonomy, Yale Kamisar

Articles

In Washington v. Glucksberg, the Court declined to find a right to physician-assisted suicide ("PAS") in the Constitution. Not a single Justice dissented. One would expect such a ruling to be quite secure. But Lawrence v. Texas, holding that a state cannot make consensual homosexual conduct a crime, is not easy to reconcile with Glucksberg. Lawrence certainly takes a much more expansive view of substantive due process than did Glucksberg. It is conceivable that the five Justices who made up the Lawrence majority-all of whom still sit on the Court-might overrule Glucksberg. For various reasons, …

Biodiversity, Baking And Boiling, Endangered Species Act Turning Down The Heat, Anna T. Moritz, Kassie R. Siegel, Brendan R. Cummings, William H. Rodgers, Jr.

Articles

Today the Earth faces an extinction event on a scale second only to Earth's largest mass extinction, the Permian-Triassic event, which occurred 250 million years ago. Upwards of 70 percent of the Earth's species could be at risk of extinction with a 3.5°C (6.3°F) rise in temperature, which could occur by the end of this century.

The driver is global warming, caused by anthropogenic greenhouse gas emissions. As such, a rational climate policy is needed immediately to prevent the complete collapse of biodiversity. Yet, the United States—the world's largest cumulative contributor to emissions—is in a state of paralysis when it …

Use Of Neutral Electrolysed Water (Ew) For Quality Maintenance And Shelf-Life Extension Of Minimally Processed Lettuce, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan, Jesus Maria Frias, Gary Henehan, José Barat

Articles

Experiments were conducted to determine the effectiveness of different treatments based on the use of neutral electrolysed water (EW) on fresh-cut lettuce. EW was diluted to obtain different free chlorine concentrations (120, 60 and 12 ppm) and compared with standard washing treatment of 120 ppm chlorine solution. Shelf-life quality and safety markers were studied at the beginning and at the end of the 7-day storage at 4 ºC. The use of EW decreased the respiration rate of the samples which might be related with the observed reduction in microbial spoilage. The use of EW also increased the activity of a …

Optimisation Of Steamer Jet-Injection To Extend The Shelf Life Of Fresh-Cut Lettuce, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan, Gary Henehan, J. Barat, Jesus Maria Frias

Articles

Optimisation of short time blanching (steaming) was investigated using response surface methodology by analysing quality and microbial and nutritional markers over the shelflife of packaged fresh-cut lettuce. Steamer treatment time (5–10 s) and storage (1–10 days) were used as independent factors in order to optimise the process. Longer treatments (>10 s) were not feasible because of extensive damage caused to lettuce tissue. Significantly (p < 0.05) higher values of luminosity (L*), greenness (−a*) and sensory panel scores (fresh appearance, general acceptability and absence of browning) were obtained with samples treated for longer times with the steamer. Activity of browning-related enzymes present in photosynthetic tissue decreased in all the cases, however, longer treatment time (7.5–10 s) was needed with vascular tissues to reduce to similar activity values. These differences could be explained by the variation in tissue thickness. The longest steam treatment (10 s) reduced and maintained significantly (p < 0.05) lower mesophilic load than shorter treatments (5–8.5 s). However, significant (p < 0.05) decreases in vitamin C and carotenoids were observed in samples treated with longer treatments. Steamer treatment of 10 s could be considered the optimum time for maintaining the shelflife (mainly texture and browning) of fresh-cut lettuce for 7–10 days in optimum conditions.

Relevance For Food Safety Of Applications Of Nanotechnology In The Food And Feed Industry, Iona Pratt, Catherine Adley, Gordon Chambers, Wayne Anderson

Articles

The application of nanotechnology in the food and feed industry offers many potential benefits for both consumers and manufacturers.The ultrafine dimensions of nanoparticles, and consequently their very large surface area, enable them to function more effectively than conventional macro-scale structures in many applications. Nanotechnology is however a relatively new area of science and the benefits and risks associated with its use in the food and feed industry are not fully understood at this time.This brings with it new challenges in ensuring the safety of food and feed that has been produced with the aid of nanotechnology. This report provides an …

Pparα Is A Key Regulator Of Hepatic Fgf21, Thomas Lundasen, Mary Hunt, Lisa-Marie Nilsson, Sabysashi Sanyal, Bo Angelin, Stefan Alexson, Mats Rudling

Articles

The metabolic regulator fibroblast growth factor 21 (FGF21) has antidiabetic properties in animal models of diabetes and obesity. Using quantitative RT-PCR, we here show that the hepatic gene expression of FGF21 is regulated by the peroxisome proliferator-activated receptor alpha (PPARalpha). Fasting or treatment of mice with the PPARalpha agonist Wy-14,643 induced FGF21 mRNA by 10-fold and 8-fold, respectively. In contrast, FGF21 mRNA was low in PPARalpha deficient mice, and fasting or treatment with Wy-14,643 did not induce FGF21. Obese ob/ob mice, known to have increased PPARalpha levels, displayed 12-fold increased hepatic FGF21 mRNA levels. The potential importance of PPARalpha for …

Extending And Measuring The Quality Of Fresh-Cut Fruit And Vegetables: A Review, Catherine Barry-Ryan, Ana Belen Martin-Diana, Daniel Rico, J. Barat

Articles

The market sales of ready-to-use fresh vegetables have grown rapidly in recent decades as a result of changes in consumer attitudes, especially consumption of fresh-cut lettuce and carrot due to their use in prepared salads. Chlorine solutions have been widely used to sanitise fruit and vegetables in the fresh-cut industry. However, the association of chlorine with the possible formation of carcinogenic chlorinated compounds in water has called into question the use of chlorine in food processing. There is a real need to find alternatives for preservation of fresh-cut fruit and vegetables in order to improve the efficacy of washing treatments. …

How Do Psychology Researchers Find Studies To Include In Meta-Analyses?, Julie Arendt

Articles

Meta-analysis is a technique used in a variety of disciplines to combine and summarize the findings of previous research. One step in the production of a meta-analysis is a thorough literature search for relevant studies. A variety of methods can be used to increase the number of studies that are found. This study examines the extent to which some of these steps were taken in meta-analyses published in American Psychological Association in journals in 2004. Some techniques were applied in almost all of the meta-analyses, and other techniques were applied in few of the meta-analyses. Implications of these results for …

Is government justified in being paternalistic? To some, the answer is yes - government sometimes knows better than people do what is best for them. If people are allowed unfettered free choice, they will not always be acting in their own best interests. Others, with a more libertarian bent, object that people know what is best for them and, in any event, should be able to do what they choose to do.

Increased Mitochondrial Mass In Cells With Functionally Compromised Mitochondria After Exposure To Both Direct Y Radiation And Bystander Factors, Sharon Nugent, Carmel Mothersill, C. Seymour, B. Mcclean, Fiona Lyng, James Murphy

Articles

The bystander effect describes radiation-like damage in unirradiated cells either in the vicinity of irradiated cells or exposed to medium from irradiated cells. This study aimed to further characterize the poorly understood mitochondrial response to both direct irradiation and bystander factor(s) in human keratinocytes (HPV-G) and Chinese hamster ovarian cells (CHO-K1). Oxygen consumption rates were determined during periods of state 4, state 3 and uncoupled respiration. Mitochondrial mass was determined using MitoTracker FM. CHO-K1 cells showed significantly reduced oxygen consumption rates 4 h after exposure to 5 Gy direct radiation and irradiated cell conditioned medium (ICCM) and an apparent recovery …
