A Review Of The Evidence Germane To The Putative Protective Role Of The Macular Carotenoids For Age-Related Macular Degeneration, Sarah Sabour-Pickett, John Nolan, James Loughman, Stephen Beatty

Articles

There is a consensus that age-related macular degeneration (AMD) is the result of (photo)- oxidative-induced retinal injury and its inflammatory sequelae, the latter being influenced by genetic background. The dietary carotenoids, lutein (L), zeaxanthin (Z), and meso-zeaxanthin (meso-Z), accumulate at the macula, where they are collectively known as macular pigment (MP). The anatomic (central retinal), biochemical (anti-oxidant) and optical (short-wavelength- filtering) properties of this pigment have generated interest in the biologically plausible rationale that MP may confer protection against AMD. Level 1 evidence has shown that dietary supplementation with broad-spectrum anti-oxidants results in risk reduction for AMD progression. Studies have …

Women, Vulnerability, And Humanitarian Emergencies, Fionnuala Ní Aoláin

Articles

The catastrophic dimensions of humanitarian emergencies are increasingly understood and more visible to states and international institutions. There is greater appreciation for the social, economic and political effects that follow in the short to long term from such catastrophes whatsoever their causes. Rhetorically too, there is some recognition of the gendered dimensions of humanitarian emergencies in policy and institutional contexts. It is generally acknowledged that women are more visible in the refugee and internally displaced communities that typically result from many humanitarian crises. Women, because of their acute care responsibilities in most societies, also disproportionately bear the brunt of familial …

This article reports on an examination of the use by state attorneys general of sixteen federal consumer protection laws that expressly allow for state enforcement. The data are sorted and analyzed by both single state actions and multistate actions over time, and by the involvement of federal agencies in the state cases. The data reveal a measured use of such powers by state attorneys general and robust state and federal cooperation …

Do Organic Cherry Vine Tomatoes Taste Better Than Conventional Cherry Vine Tomatoes? A Sensory And Instrumental Comparative Study From Ireland, Clare Gilsenan, Roisin Burke, Catherine Barry-Ryan

Articles

A consumer panel was able to distinguish a perceptible difference between organically farmed and conventionally produced tomatoes, and preferred the taste of the conventional tomatoes. The sensory evaluation results of the trained panel revealed that the conventional tomatoes were sweeter and less sour than the organic tomatoes. In addition to this, the conventional tomatoes showed significant differences for ^oBrix, reducing sugars and electrical conductivity. No significant differences were observed between the organic and conventional tomato samples for color, size, firmness, pH and dry matter values.

Another Word On The President's Statutory Authority Over Agency Action, Nina A. Mendelson

Articles

In this short symposium contribution, I attempt first to add some further evidence on the interpretive question. That evidence weighs strongly, in my view, in favor of Kagan's conclusion that the terminology does not communicate any particular congressional intent regarding presidential directive authority. Assessed in context, the "whole code" textual analysis presented by Stack does not justify the conclusion that Congress, by delegating to an executive branch official, meant to limit presidential control. Independent agencies excluded, interpreting the terms of simple and presidential delegations to speak to directive authority fails, in general, to make sense of the various statutes. Absent …

Effect Of Processing Conditions On Phytochemical Constituents Of Edible Irish Seaweed Himanthalia Elongata., Sabrina Cox, Nissreen Abu-Ghannam, Shilpi Gupta

Articles

Seaweed iswell recognized as an excellent source of phytochemicals. This study was a preliminary screening to investigate the effects of various food processing methods on the phytochemicals of Himanthalia elongata. Hydrothermal processing was carried out until an edible texture was achieved. The total phenolic content (TPC) of fresh H. elongata was 175.27 mg gallic acid equivalent (GAE)/100 g fresh weight (FW) while boiling significantly reduced the TPC to 25.4 mg GAE/100 g FW
(P < 0.05).A drying pretreatment before boiling reduced the cooking time therefore leading to less leaching of antioxidants upon boiling. In terms of extract, drying of H. elongata followed by boiling had the most significant effect on the phytochemicals as TPC increased by 174%. Boiled extracts had the most effective 2, 2-diphenyl- 1-picrylhydrazyl scavenging activity (EC50 of 12.5 mg/mL). As a comparison, seaweed subjected to the same treatments was studied in terms of antimicrobial activity.Overall, extracts fromfresh H. elongata achieved the highest inhibition.

Modelling The Effect Of Asparaginase In Reducing Acrylamide Formation In Biscuits, Monica Anese, Barbara Quarta, Jesus Maria Frias

Articles

The influence of asparaginase on acrylamide formation, as well as colour development, in short dough biscuits was studied. In particular, asparaginase concentration, incubation time and temperature were changed according to an experimental design. As acrylamide formation was found to vary significantly between biscuits obtained by using the same ingredients and process, a mixed effect model was used to model variation of acrylamide concentration. By contrast a fixed effect model was used for colour polynomial analysis. Within the range of study, the overall results allowed the best conditions for minimising acrylamide formation to be found. It can be suggested that acrylamide …

Bioactive Potential And Possible Health Effects Of Edible Brown Seaweeds, Shilpi Gupta, Nissreen Abu-Ghannam

Articles

Marine macroalgae (seaweeds) are rich in bioactive compounds that could potentially be exploited as functional ingredients for both human and animal health applications. Despite the intensive efforts that are being made to isolate and identify new compounds with potential medicinal, health or pharmaceutical activities, very few compounds with real potency are available. Bioactive compounds that are most extensively researched include sulfated polysaccharides, phlorotannins and diterpenes. These compounds have been reported to possess strong anti-viral, anti-tumor and anti-cancer properties. At the same time, the prebiotic health potential of the polysaccharides from seaweeds is also increasingly being studied either by feeding whole …
