From the early history of humanity until today, fish and other fishery products have always been involved in human diet. The intake of a sufficient number of proteins has been enabled through high-quality fish meat containing a significant quantity of essential amino acids as well as omega-3 fatty acids. According to the studies, 150 grams of fish, meets the needs of a 50-60% of daily protein intake for an adult. A large part of fishery production in Turkey (86%), is consumed fresh. Turkey, within the scope of Common Fisheries Policy is trying to harmonize fisheries with the EU. A failure to update the 1380 coded Fisheries Law and rapid issuing of EU compatible regulations, safe food for consumers, high quality products along the year for processing industry and marketers, as well as the inability to ensure sustainable price development for the producers, prevent the success of the sector. The aim of this study was to determine the consumption behavior when taking fishery products in terms of food safety, reliability, product quality as well as the level of income and education.

The nutrient composition of 15 commercially available microalgae powders of Arthrospira platensis, Chlorella pyrenoidosa and vulgaris, Dunaliella salina, Haematococcus pluvialis, Tetraselmis chuii, and Aphanizomenon flos-aquae was analyzed. The Dunaliella salina powders were characterized by a high content of carbohydrates, saturated fatty acids (SFAs), omega-6-polyunsaturated fatty acids (n6-PUFAs), heavy metals, and α-tocopherol, whereas the protein amounts, essential amino acids (EAAs), omega-3-PUFAs (n3-PUFAs), vitamins, and minerals were low. In the powder of Haematococcus pluvialis, ten times higher amounts of carotenoids compared to all other analyzed powders were determined, yet it was low in vitamins D and E, protein, and EAAs, and the n6/n3-PUFAs ratio was comparably high. Vitamin B12, quantified as cobalamin, was below 0.02 mg/100 g dry weight (d.w.) in all studied powders. Based on our analysis, microalgae such as Aphanizomenon and Chlorella may contribute to an adequate intake of critical nutrients such as protein with a high content of EAAs, dietary fibers, n3-PUFAs, Ca, Fe, Mg, and Zn, as well as vitamin D and E. Yet, the nutritional value of Aphanizomenon flos-aquae was slightly decreased by high contents of SFAs. The present data show that microalgae are rich in valuable nutrients, but the macro- and micronutrient profiles differ strongly between and within species.

Abstract Objectives The aim of this study was to assess the dietary intakes of lutein, zeaxanthin (L + Z) and omega-3-essential fatty acid(EFA) among a selected population of Australian based adults and to examine the effect of specified risk factors for age-related macular degeneration(AMD) on those levels. Methods A cross-sectional study involving 70 adults aged 19–52 years was carried out. Demographic data were obtained using an online self-administered questionnaire while dietary intakes were estimated using USDA's 24 hours recall questionnaire, the Victorian Cancer Council(Australia) food frequency questionnaire and anthropometric characteristics were obtained using a body composition analyzer. Dietary intakes of lutein, zeaxanthin, omega-3-EFA and anthropometric indices against the risk of AMD were established using descriptive statistics and Spearman correlation. Results The mean age of the population was 29.9 ± 8.1years with 51% men and 49% women. Women had a higher intake of L + Z (1908.6 μg/day versus 1032.8 μg/day) and alpha-linolenic acid(ALA) compared to men(1.7 ± 1.1 g/day versus 1.6 ± 1.2 g/day). Men consumed more omega-3-EFA than women (433 ± 397.1 mg/day versus 365 ± 210.7 mg/day). L + Z levels were higher among people of Middle Eastern and South Asian origin (>4000 μg/day) in the 19–25years age group. People of Middle Eastern, South East Asian and South Asian had the highest intake of omega-3-EFA(>500 mg/day) at ages 19–25, 26–32 and 34–52years respectively. Women aged 34–52years with a family history of AMD had higher levels of L + Z(>2500 μg/day) while women aged 26–32years with a family history of AMD had higher levels of ALA(>3 g/day). Ethnicity and L + Z were correlated (P = −0.456, P < 0.02). Higher levels of intake of L + Z (>4000 μg/day) were seen in participants aged 34–52years with a 5–10years residence in Australia. Participants who had less than 5–10years of residency had higher levels of omega-3-EFA(>500 mg/day) for ages 26–32years while those aged 34–52years who had less than 5years of residency had higher ALA(>4 g/day). Conclusions Intake levels for L + Z vary significantly among participants. Culturally specific dietary habits could feasibly influence the levels of intake of L + Z. Intake levels of omega-3-EFA were met. This study provides detailed intake levels of L + Z and omega-3-EFA for the ‘at-risk’ AMD group. Funding Sources No funding source.

Abstract Background Ulcerative colitis (UC) has been associated with an increased risk of colorectal cancer (CRC). Although dye spray chromoendoscopy showed superiority to standard colonoscopy in surveillance studies, with the availability of higher-resolution colonoscopes, the utility of chromoendoscopy (CE) has been questioned. We aimed to evaluate the risk of intraepithelial neoplasia (IN) after a high-quality screening colonoscopy (making use of CE or random biopsies (RB) and removing all detected lesions) in a population with longstanding UC and to identify potential risk factors for dysplasia incidence. Methods In a previous study, 145 patients with clinically and endoscopic longstanding (≥8 yr) distal/extensive UC without primary sclerosing cholangitis and/or history of IN were prospectively randomised to undergo CE or RB. In this study, after a median follow-up of 5 additional years, we evaluated subsequent IN incidence in these patients, submitted to surveillance colonoscopy. Patients without high-quality surveillance colonoscopy (with good bowel preparation and cecum intubation) using high-definition were excluded. Results One hundred and twenty-one patients were included. Nine had removed adenomas with low-grade dysplasia in the index colonoscopy. Now, in surveillance colonoscopy, we detected 9 (7.4%) IN: low-grade dysplasia was found in 8 (6.6%) patients and a colorectal adenocarcinoma in 1 (0.008%) patient. After multivariate analysis, IN was significantly associated with older age (68 vs. 52 years, p < 0.05) and higher disease duration (26 vs. 20 years, p < 0.05). No association was found between IN and previous detection of IN in screening colonoscopy sex, the CE or RB use in index colonoscopy, extent of disease, The presence of pseudopolyps, smoking habits, familial history of CRC or maintenance therapy for UC. Conclusion In this study, older patients and higher disease duration were associated with a higher risk of IN in surveillance colonoscopy.

Pampus Argenteus

Marine fish are well-known for being a high-quality protein source having high concentration of essential amino acids. It has high concentration of mono unsaturated and poly unsaturated fatty acids, which may aid in the optimization of lipid profiles and the reduction of the risk of coronary heart disease (CHD). The goal of this study was to estimate the nutritional and biochemical status of raw sea fish Pampus argenteus after 30 days of frozen storage at -200C with 15-day intervals. Nutrient study showed a decrease in protein and lipid content. The changes of hydrogen peroxide and oxidized lipid products were estimated in the muscle tissue during fresh and storage condition. Results indicate that during storage the oxidative stress increased. An antioxidant enzyme (superoxide dismutase, smutase, catalase, glutathione peroxidase) measurement was determined. The increased amount of oxidative stress during fish storage is shown by the differential activity of antioxidant enzymes. The amount of protein in fish varies slightly between species and even within species. Fish is high in protein, vitamins, minerals, and omega-3 fatty acids, which are essential for brain development (Spencer et al., 1971; Jacylin et al., 2010). A well-balanced diet consists variety of fish that can help in children's growth and development as well as their heart health (Jinadasa, 2014).

Opening ParagraphWestern scientific culture finds itself in a singular position with respect to the magico-religious system embodied in medieval culture from which, after strenuous resistence from the contemporary ecclesiastical authorities, it originally broke free. That is to say, it has still not succeeded in forming a theory concerning that very class of phenomena with which it was sometimes obliged violently to struggle in order to constitute itself as an autonomous discipline. And we, despite the proliferation of ethnographic and historical studies of extremely high quality, are hardly more advanced than in 1902, when Marcel Mauss and Henri Hubert (1950: 138) wrote: ‘Until now the history of religions has relied on a rag-bag of vague ideas … the science of religions does not yet possess a scientific nomenclature’.

Abstract The two main classes of vulcanized oil substitute or factice are heat-cured brown factice and cold-cured white factice. They were both introduced into the rubber industry at about the same time (1846–1847), the former variety by Anderson and the latter by Parkes. It has been stated (Twiss, Trans. Inst. Rubber Ind., 7, 234 (1931)) that Parkes first opened a proofing factory at Birmingham but that the business was shortly afterwards absorbed by Chas. Macintosh & Co. and transferred to Manchester. This probably dates the commencement of the use of white factice in proofings. The early history of the development of the use of brown factice on a works scale is more obscure. As the name implies, these vulcanized oils were used in the first place as ingredients which could economically substitute part of the crude rubber content of mixings, but as time went on it became apparent to compounders that these materials possessed intrinsic properties which made them almost indispensable in certain mixings, both for ease of manufacture and for high quality of the resultant article. The utility of factices in the general rubber trade is therefore in many respects analogous to that of reclaimed rubbers.

Emerging evidence of brain injury on risk of neurodegenerative diseases such as Alzheimer’s disease (AD) and chronic traumatic encephalopathy (CTE) have resulted in interest in therapeutic potential of omega-3 fatty acids (n-3FA). We conducted a systematic review of n-3FA therapeutic efficacy for ageing adults at risk of AD/CTE following a history of repeated head trauma. Databases for articles between 1980-June 2020 were examined for studies reporting on n-3 FAs in adults (≥ 45 years) with a history of repeated brain injury. Following an initial screen of 175 articles, 12 studies were considered but were eventually rejected, as they did not meet inclusion criteria. Our review could find no evidence to support, or disprove, effectiveness of n-3FA intervention in older adults with a history of head trauma. With animal studies showing neuro-restorative potential of n-3FA following brain injury, this review highlights the urgent need for human research in this area.

We have followed the story of the Three Age System a very long way indeed. We saw how it emerged in Copenhagen and Lund, how it was received there, and how Worsaae fought to establish it there. We then saw how it came to Britain, and followed in Worsaae’s footsteps from London to Edinburgh to Dublin and back to London again. In each of the three capitals in which it was considered, accepted or rejected, the academic context was quite different from the others. In London the archaeologists were safe sheltering under the dominant ethnological paradigm, and for some time saw no reason to venture out from beneath it. In Edinburgh the Four Stage Theory and long links with Denmark made the Scandinavian story much easier to swallow rapidly. In Dublin the historical elite was so blinded by the glory of their ancient history that there was no place for the archaeological theory, and it had to be carried into the capital by an originally provincial archaeological movement. Back in London, the safe ethnological chronology was jolted out of alignment by the discovery of human antiquity, and alongside this—and on the back of high-quality archaeological excavation—the Three Age System finally won the day. Some aspects of the story have long been well known. The roles of C. J. Thomsen, of J. J. A. Worsaae, of Daniel Wilson, and of John Lubbock have all received much exposure in discussions of the history of archaeology. But in following this story we have also sometimes looked beneath stones that have seldom if ever previously been lifted in this connection, at least in the Anglophone literature. It has for example rarely been understood that Thomsen’s ‘idea of prehistory’ was not simply forging back into hitherto uncharted chronological territory, but was to begin with leaning on the elaborate ancient historical structure of Peter Frederik Suhm. It was only when Christian Molbech kicked away this structure in the 1830s that the Three Age System had to stand on its own. Fortunately it was rapidly supported by three other chronologies employing physical evidence, and they acted as supports in its very earliest days of independence. When Worsaae hastened ancient history into its grave in the 1840s, the Three Age System was therefore able to stand on its own four feet (archaeology, economy, ecology, and craniology).

Bee pollen is made by honey bees (Apis Mellifera) from the pollen of plants and flowers and represents an apiary product enriched in essential amino acids, polyphenols, omega-3, and omega-6 fatty acids. This study investigated the botanical origin, micronutrient profile, and antioxidant activity of bee pollen samples (n = 10) harvested in Lucca and Massa Carrara (Tuscany, Italy) between 2016 and 2017. The palynological analysis showed that bee pollen samples were composed of nine botanical families. Front-face fluorescence spectroscopy was performed on bee pollen samples in bulk, without any treatment, and in ethanol extracts to determine the characteristic fluorescent profile and, to identify the main chemical compounds with biological activity. The main chemical compounds detected were polyphenols (mainly flavonoids and phenolic acids), hydro-soluble vitamins (B2, B3, B6, and B9), amino acids, and pigments. Furthermore, the antioxidant activity was investigated, and one of the two Viburnum pollens resulted in the highest polyphenols and flavonoids content (20.15 ± 0.15 mg GAE/g fw and 23.46 ± 0.08 mg CE/g fw, respectively). However, Prunus and Eucalyptus families showed the highest in vitro (190.27 ± 8.30 µmol Fe2+/g) and ex vivo (54.61 ± 8.51 CAA unit) antioxidant capacity, respectively. These results suggested that Tuscan bee pollen, depending on the botanical family, is rich in essential nutrients and potential nutraceutical product.

Abstract There has long been a tension between environmental regulation and the European Common Fisheries Policy (CFP), which has been addressed over time through progressive reform of the CFP. It is now recognised that Member States may comply with their obligations under EU nature conservation law by taking unilateral non-discriminatory measures within their territorial seas to protect the marine environment from threats posed by fishing. Nevertheless, fundamental uncertainties remain when it comes to the application of these obligations to offshore waters. This article explores the options available to coastal states in this context and the weaknesses of the procedures introduced to the reformed CFP in 2013. It is argued that compliance with nature conservation law in the context of fisheries is not discretionary and that in the absence of measures agreed at the EU level, Member States must comply with their obligations under the Habitats Directive in their capacity as a flag state. Finally, the article addresses the implications of Brexit for the protection of European Marine Sites in UK waters, suggesting that Brexit offers opportunities to strengthen the protection of marine ecosystems by making future access arrangements for foreign fishing vessels conditional upon compliance with nature conservation laws.
