Consumer perception of different species and presentation forms of fish: An empirical analysis in Italy
No full textFish consumption analysis involves public and commercial interests. Many studies have focused on this issue over the last few decades. Researchers rarely consider the heterogeneity of these products, while we believe there are at least five reasons why it should always be taken into account: (i) health factors; (ii) environmental drawbacks regarding the consumption of particular species; (iii) the importance of species and how the fish are presented to consumers; (iv) the perceived differences between species are of prime importance for marketing strategies; and finally (v) being able to identify different species helps prevent fraud. Through perceptual mapping we studied the perceived differences between European anchovies (Engraulis encrasicholus), European sardines (Sardina pilchardus) and mackerel (Sgomber spp.), wild-caught cod and sole, and farmed sea bream and sea bass. We checked for the influence of gender, age, education and residence in how consumers perceive seafood. We found that the gender, age and education of consumers do not usually affect their perception of blue fish as being cheap, flavorsome and traditional, cod and sole as nutritional, and farmed sea bream and bass as natural. A slight difference was found in central/southern Italian residents, who perceive farmed sea bream and bass as cheap and flavorful. The results validate the idea that consumers recognize the different attributes of each species or type of fish for sale, but some issues remain unresolved and further studies are recommended

Chronic and intermittent administration of systemic nitroglycerin in the rat induces an increase in the gene expression of CGRP in central areas: potential contribution to pain processing
No full textAbstract Background Calcitonin gene related peptide (CGRP) is a key neuropeptide involved in the activation of the trigeminovascular system and it is likely related to migraine chronification. Here, we investigated the role of CGRP in an animal model that mimics the chronic migraine condition via repeated and intermittent nitroglycerin (NTG) administration. We also evaluated the modulatory effect of topiramate on this experimental paradigm. Male Sprague-Dawley rats were injected with NTG (5 mg/kg, i.p.) or vehicle, every 2 days over a 9-day period (5 total injections). A group of animals was injected with topiramate (30 mg/kg, i.p.) or saline every day for 9 days. Twenty-four hours after the last administration of NTG or vehicle, animals underwent tail flick test and orofacial Von Frey test. Rats were subsequently sacrificed to evaluate c-Fos and CGRP gene expression in medulla-pons region, cervical spinal cord and trigeminal ganglia. Results NTG administration induced spinal hyperalgesia and orofacial allodynia, together with a significant increase in the expression of CGRP and c-Fos genes in trigeminal ganglia and central areas. Topiramate treatment prevented NTG-induced changes by reversing NTG-induced hyperalgesia and allodynia, and inhibiting CGRP and c-Fos gene expression in all areas evaluated. Conclusions These findings point to the role of CGRP in the processes underlying migraine chronification and suggest a possible interaction with gamma-aminobutyrate (GABA) and glutamate transmission to induce/maintain central sensitization and to contribute to the dysregulation of descending pain system involved in chronic migraine
