Effect of a peel passion fruit flour (Passiflora edulis f. flavicarpa) extract on the labeling of blood constituents with technetium-99m and on the morphology of red blood cells 52
Rebello,Bernardo Machado; Moreno,Silvana Ramos Farias; Ribeiro,Camila Godinho; Neves,Rosane de Figueiredo; Fonseca,Adenilson de Souza da; Caldas,Luis Querino de Araújo; Bernardo-Filho,Mario; Medeiros,Aldo da Cunha.
Passiflora edulis f. flavicarpa (maracuja) is a fruit consumed in Brazil and worldwide. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The effect of P. flavicarpa extract on the radiolabeling of blood constituents and on red blood cells morphology was evaluated. Blood samples from Wistar rats was incubated with P. flavicarpa extract. After that, the labeling of blood constituents with 99mTc was carried out. Samples of plasma and blood cells were precipitated with trichloroacetic acid to isolate the soluble and insoluble fractions of plasma and blood cells. The radioactivity in each fractions was counted and the percentage of radioactivity was determined. Blood smears were also prepared to morphological evaluation and...

Preparation of crotalus venom radiolabeled with technetium-99m as a tool for biodistribution study 52
Pujatti,Priscilla Brunelli; Simal,Carlos Jorge Rodrigues; Santos,Raquel Gouvêa dos.
Technetium-99m (99mTc) has been the radionuclide of choice for nuclear medicine procedures and experimental research. Because of its optimal nuclear properties, 99mTc is suitable for high efficiency detection with the advantage of reduced radiological waste. Crotalus venom (CV) has been shown to reduce tumors in clinical studies and tissue distribution studies are very important for clinical use. The goal of this work was to obtain CV labeled with 99mTc which preserves its biological activity. After labeling, biological activity was assessed by hemolytic activity evaluation. Labeled and crude venom caused indirect hemolysis provided that the incubation medium contained an exogenous source of lecithin. High yield radiolabeled-CV was obtained and biological...

The aim of this work was to evaluate the effect of an extract of the Artemisia vulgaris L. (mugwort) on the labeling of blood constituents with technetium-99m (99mTc). Blood samples from Wistar rats were incubated with a mugwort extract and the radiolabeling of blood constituents was carried out. Plasma and blood cells were separated by centrifugation. Aliquots of plasma and blood cells were also precipitated with trichloroacetic acid and centrifuged to isolate soluble and insoluble fractions of plasma and blood cells. Radioactivity in each fraction was counted and the percentages of radioactivity (%ATI) was calculated. Mugwort extract decreased significantly (p<0.05) the %ATI on the blood compartments and on the blood cells proteins (insoluble...

Ion specificity in determining physico-chemical properties of drinking water 116
PREZIOSO,Domenico; DI DOMENICO,Dante; PANE,Manuela; CICCARELLI,Donato; D’ERRICO,Gerardino.
Abstract Drinking water plays a key role in regulating the daily salt intake, thus potentially affecting (either in positive or in negative direction) the incidence of diet-related pathologies, including nephrolithiasis. Being regarded as wholesome, bottled water is increasingly preferred to tap water. However, its physico-chemical characterization, as reported on the label, is usually limited to pH and conductivity measurements, along with ion content. Other parameters, which also are likely to influence the processes in which water is involved in the body, are usually neglected. In this work, the surface tension and density of tap water and two bottled mineral waters produced in Italy are investigated. These parameters are critically determined by the...

Labeling Regulations and Segregation of First- and Second-Generation Genetically Modified Products: Innovation Incentives and Welfare Effects 31
Moschini, GianCarlo; Lapan, Harvey E..
We review some of the most significant issues and results on the economic effects of genetically modified (GM) product innovation, with emphasis on the question of GM labeling and the need for costly segregation and identity preservation activities. The analysis is organized around an explicit model that can accommodate the features of both first-generation and second-generation GM products. The model accounts for the proprietary nature of GM innovations and for the critical role of consumer preferences vis-a-vis GM products, as well as for the impacts of segregation and identity preservation and the effects of a mandatory GM labeling regulation. We also investigate briefly a novel question in this setting, the choice of 'research direction' when both...

Do Native and Invasive Labels Affect Consumer Willingness to Pay for Plants? Evidence from Experimental Auctions 31
Yue, Chengyan; Hurley, Terrance M.; Anderson, Neil O..
The ultimate objective of commercial horticultural activities is to satisfy the needs of the final consumer. Consumer demand for novel plants drives the ornamental plant industry. Therefore, dispersal of native and invasive horticultural plants can be understood by considering the decisions/choices of consumers who decide which plants to purchase from retailers. In contrast to previous studies on invasive and native plants, this study uses an experimental auction to elicit consumers’ willingness to pay (WTP) for labeled native and invasive attributes. Results from a censored random effect model show that consumers’ WTP for plants decreases when the plants are labeled as invasive and increases when plants are labeled as native. The study finds that...

Western Australian Consumers’ Attitudes Towards Genetically Modified Canola (Brassica napus) 31
Baumann, Annette; Lumley, Sarah; Rumley, Dennis; Fenna, Alan.
Products made from GM canola need wide consumer acceptance to be commercialised. This study aims to investigate whether or not Western Australian consumers would be willing to consume GM canola products, and how much they would be willing to pay for them. A survey covering 500 randomly selected Western Australians was made. Preliminary results show that more than 50% of consumers would buy non-GM canola oil, even if it costs one dollar more than the GM canola oil. It was suggested that the Australian Commonwealth and State Governments should establish adequate labelling of GM products, in order to increase consumers’ awareness. Further socio-economic research is required on GM crops.

Analysis of Consumer Preferences for Biotech Labeling Formats 31
Harrison, R. Wes; Mclennon, Everald.
Conjoint analysis is used to measure the preferences of United States consumers for labeling of biotech foods. The study found that consumers in the sample support mandatory labeling of biotech foods. This suggests that U.S. consumers would support revisions to the present voluntary labeling policy of the U.S. Food and Drug Administration and the U.S. Department of Agriculture. Results also showed that the preferred labeling formal is a text disclosure that describes the benefits of biotechnology in combination with a biotech logo.

Identifying Market Preferences for High Selenium Beef 31
Hovde, Scott C.; Wachenheim, Cheryl J.; Hearne, Robert R.; Nganje, William E..
Selenium is an element found in relatively high concentrations in crops and livestock raised on high-selenium soils located in North and South Dakota. Evidence suggests that a high-selenium diet such as would be obtained from consuming these products can reduce the risk of certain cancers. The region's livestock and grain producers are exploring potential high-selenium product marketing opportunities. A choice experiment was conducted to identify preferred attributes for a high-selenium beef product and the characteristics of potential market segments. In a national survey, participants chose between different levels of health claim approval and research, prices, and selenium origin. A multinomial logit regression model was estimated. Labeling...

Il quadro normativo sulle denominazioni commerciali dei prodotti ittici nella gestione delle frodi: strumento di gestione o problema irrisolto? 31
Gaviglio, Anna; Pirani, Alberto; Demartini, Eugenio.
Authors suppose the amounts of fraudulent seafood sales reported in recent years to be somehow correlated to the problems of Italian commercial fish-naming policy. However, given the lack of data and studies, the work has an exploratory nature focusing on three main issues: the seafood labeling policy framework, the evolution of lists of fish species’ trade names and the spread and type of fraudulent sales. According data authors believe that the fish-naming system is improving, however that lack of studies estimating the right amount of diversification in trade names for marine species seems so to be a weakness for a winning policy. Furthermore, seafood retailers seems to assume an important role on fraud management and government should support research...

Market Differentiation Potential of Country-of-origin, Quality and Traceability Labeling 31
Verbeke, Wim; Roosen, Jutta.
Product labeling has gained considerable attention recently, as a means to both provide product-specific information and reduce quality uncertainty faced by consumers, as well as from a regulatory point of view. This article focuses on whether and to what extent origin, quality and traceability labeling is an appropriate way to differentiate food products. The focus is on fresh meat and fresh fish, two mainly generic food product categories with a high degree of credence character. Insights into the potential for market differentiation through origin, quality and traceability labeling are provided and discussed using primary data collected during the period 2000-2005 by means of four consumer surveys. In general, direct indications of quality, including...

ECONOMICS OF FOOD LABELING 31
Golan, Elise H.; Kuchler, Fred; Mitchell, Lorraine.
Federal intervention in food labeling is often proposed with the aim of achieving a social goal such as improving human health and safety, mitigating environmental hazards, averting international trade disputes, or supporting domestic agricultural and food manufacturing industries. Economic theory suggests, however, that mandatory food-labeling requirements are best suited to alleviating problems of asymmetric information and are rarely effective in redressing environmental or other spillovers associated with food production and consumption. Theory also suggests that the appropriate role for government in labeling depends on the type of information involved and the level and distribution of the costs and benefits of providing that information. This report...

Promoting Organic Food: Information Policy Versus Production Subsidy 31
Tribl, Christoph; Salhofer, Klaus.
In developed countries governments aim to increase the market share of organic products. Assuming that organic farming creates a positive externality, we address the question of how this environmental benefit can be internalized best. Using the concept of heterogeneous producers and consumers we compare two policy options to enhance organic supply and demand with respect to their efficiency and distributional effect: First, we analyze the effect of a supply-side oriented policy like a subsidy on organic production. Second, we compare this policy measure to a demand-side oriented information policy, which aims to enhance the acceptance and identification of an organic food label. Third, we assume a mix of both policy measures. The main findings of this...

Food Safety and Imports: An Analysis of FDA Food-Related Import Refusal Reports 31
Buzby, Jean C.; Unnevehr, Laurian J.; Roberts, Donna.
This report examines U.S. Food and Drug Administration (FDA) data on refusals of food offered for importation into the United States from 1998 to 2004. Although the data do not necessarily reflect the distribution of risk in foods, the study found that import refusals highlight food safety problems that appear to recur in trade and where the FDA has focused its import alerts, examinations (e.g., sampling), and other monitoring efforts. The data show some food industries and types of violations are consistent sources of problems both over time and in comparison with previous studies of more limited data. The three food industry groups with the most violations were vegetables (20.6 percent of total violations), fishery and seafood (20.1 percent), and fruits...

ECONOMIC EFFECTS OF PURITY STANDARDS IN BIOTECH LABELING LAWS 31
Giannakas, Konstantinos; Kalaitzandonakes, Nicholas G..
This paper develops a model of heterogeneous consumer preferences to analyze the market and welfare effects of reduced purity standards for non-GM labeled food. Analytical results show that purity standards affect the equilibrium prices and quantities of both the GM and non-GM products as well as the welfare of the groups involved. A change in purity standards is shown to create winners and losers among the consumers as well as among the suppliers of the GM and conventional products.

A Model of Labeling with Horizontal Differentiation and Cost Variability 31
Saak, Alexander E..
We study optimal disclosure of variety by a multi-product firm with random costs. In our model there are two varieties that are horizontally differentiated and differ in overall quality, but buyers cannot distinguish between them without labels. The equilibrium prices for labeled varieties are increasing functions of the absolute value of the cost differential and do not reveal which variety is cheaper to produce. Nondisclosure is most common when there is moderate uncertainty about the relative input cost, not too much idiosyncrasy in consumer valuations, and not too much difference in quality across varieties. Although mandatory disclosure of variety benefits consumers, it decreases expected welfare when relative input cost variability is large and...

Environmental Labeling, Protected Geographical Indications and the Interests of Developing Countries 31
Grote, Ulrike.
Among developing countries, one can identify both proponents and opponents of extending the use of geographical indications (GIs) beyond wines and spirits. Such an extension is currently being discussed under the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) of the World Trade Organization. While labeling is mostly based on private initiatives, GIs are considered to be long-term public rights. Proponents therefore regard GIs as the stronger tools for protecting their national property rights and offering them new opportunities to develop their export markets. Opponents, however, consider GIs to be new barriers to trade that impede their export opportunities. This article clarifies these positions and pulls together some...
