    2013-07-01

    Presented are the research objectives of the project "Irep en Kemet", Wine of Ancient Egypt, and the content of the project's website. This research aims at documenting the complete corpus of wine in ancient Egypt and analysing the data (iconography, textual sources and artefacts) to unveil the importance of the ancient Egyptian wine culture legacy in the Mediterranean region. At this stage, a bibliographical researchable database relevant to wine, viticulture and winemaking in the ancient Egypt has been completed, with 197 entries including articles, books, chapters in book, academic thesis (PhD and MA), essay, abstracts, on-line articles and websites. Moreover, a scene-detail database for the viticulture and winemaking scenes in the Egyptian private tombs has been recorded with 97 entries, some of them unpublished, and the collected data is under study. The titles of the tombs' owners and the texts related to the scenes will be also recorded. A photographic survey of the graves containing images related with viticulture and winemaking will be carried out in order to have the most accurate information on the location and stage of conservation of those images. Our main goal is to provide scholars with a complete, comprehensive archaeological and bibliographical database for the scenes of viticulture and winemaking depicted in the Egyptian private tombs throughout the ancient Egyptian history. The project's website (http://www.wineofancientegypt.com) will include all the collected data, the study and analysis, the project's history and team members, publications as well as the results of our research.

    Full Text Available Ultrahigh-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry (UPLC-QTOF/MS was developed for rapid and sensitive analysis of the effect of rice wine on the metabolites of the main components of herbal medicine in rat urine. Using Cornus officinalis as a model of herbal medicine, the metabolite profiles of crude and processed (steaming the crude drug presteeped in rice wine Cornus officinalis extracts in rat urine were investigated. The metabolites of Cornus officinalis were identified by using dynamic adjustment of the fragmentor voltage to produce structure-relevant fragment ions. In this work, we identified the parent compounds and metabolites of crude and processed Cornus officinalis in rats. In total, three parent compounds and seventeen new metabolites of Cornus officinalis were found in rats. The contents of the parent compounds and metabolites in vivo varied significantly after intragastric (i.g. administration of aqueous extracts of crude and processed Cornus officinalis. Data from this study suggests that UPLC-QTOF/MS could be used as a potential tool for uncovering the effects of excipients found in the metabolites of the main components of herbal medicine, in vivo, to predict and discover the processing mechanisms of herbal medicine.

    Diagonal, transit, and Ramesside star clocks are tables of astronomical information occasionally found in ancient Egyptian temples, tombs, and papyri. The tables represent the motions of selected stars (decans and hour stars) throughout the Egyptian civil year. Analysis of star clocks leads to greater understanding of ancient Egyptian constellations, ritual astronomical activities, observational practices, and pharaonic chronology.

  12. Ancient Egyptian Medicine: A Systematic Review

    Directory of Open Access Journals (Sweden)

    Samuel Adu-Gyamfi

    Full Text Available Our present day knowledge in the area of medicine in Ancient Egypt has been severally sourced from medical papyri several of which have been deduced and analyzed by different scholars. For educational purposes it is always imperative to consult different literature or sources in the teaching of ancient Egypt and medicine in particular. To avoid subjectivity the author has found the need to re-engage the efforts made by several scholars in adducing evidences from medical papyri. In the quest to re-engage the efforts of earlier writers and commentaries on the medical papyri, we are afforded the opportunity to be informed about the need to ask further questions to enable us to construct or reconstruct both past and modern views on ancient Egyptian medical knowledge. It is this vocation the author sought to pursue in the interim, through a preliminary review, to highlight, comment and reinvigorate in the reader or researcher the need for a continuous engagement of some pertinent documentary sources on Ancient Egyptian medical knowledge for educational and research purposes. The study is based on qualitative review of published literature. The selection of those articles as sources was based on the focus of the review, in order to purposively select and comment on articles that were published based either on information from a medical papyrus or focused on medical specialization among the ancient Egyptians as well as ancient Egyptian knowledge on diseases and medicine. It was found that the Egyptians developed relatively sophisticated medical practices covering significant medical fields such as herbal medicine, gynecology and obstetrics, anatomy and physiology, mummification and even the preliminary form of surgery. These practices, perhaps, were developed as remedies for the prevailing diseases and the accidents that might have occurred during the construction of their giant pyramids. It must be stated that they were not without flaws. Also, the

  13. Wine phenolics.

    Science.gov (United States)

    Waterhouse, Andrew L

    2002-05-01

    Wine contains many phenolic substances, most of which originate in the grape berry. The phenolics have a number of important functions in wine, affecting the tastes of bitterness and astringency, especially in red wine. Second, the color of red wine is caused by phenolics. Third, the phenolics are the key wine preservative and the basis of long aging. Lastly, since phenolics oxidize readily, they are the component that suffers owing to oxidation and the substance that turns brown in wine (and other foods) when exposed to air. Wine phenolics include the non-flavonoids: hydroxycinnamates, hydroxybenzoates and the stilbenes; plus the flavonoids: flavan-3-ols, the flavonols, and the anthocyanins. While polymeric condensed tannins and pigmented tannins constitute the majority of wine phenolics, their large size precludes absorption and thus they are not likely to have many health effects (except, perhaps, in the gut). The total amount of phenols found in a glass of red wine is on the order of 200 mg versus about 40 mg in a glass of white wine.

  14. SENSORY PROPERTIES OF SOME WHITE WINES, FLAVORED WINES AND VERMOUTH TYPE WINES, PREPARED BY USING OWN RECIPES

    2015-04-01

    Full Text Available In order to characterize, from sensorial point of view, the basic white wines White Fetească, Italian Riesling, Sauvignon Blanc, as well as flavored wines and vermouth type wines, obtained by addition of hydroalcoholic plants macerates to basic wines, tasting technique was used. It is known that sensory analysis is a method that can provide an overview of a wine. The main features analyzed were: appearance, color, smell and taste. Initial, wines presented specific features of grapes variety from which they belong, being characterized by harmony and complex flavor. The hydroalcoholic macerates were obtained by preparing two recipes (labeled I and II of different mixtures of plants. Recipes I A in 45% alcohol and I B in 60% alcohol, had characteristics of appearance, color, taste and smell, very intense, specific, prevailing the taste of anise, fennel and coriander. The macerates prepared with recipes II A in 45% alcohol and II B in 60% alcohol (mixture of a few herbs and peel of citrus fruits showed peculiarities of taste, odor, flavor less intense, prevailing the smell of nutmeg and citrus flavor. Recipes I A and I B of hydroalcoholic plants macerates decisively influenced the color, taste, flavor, smell and appearance of flavored wines. Recipes II A and II B influenced discreetly the sensory properties of flavored wines. Vermouth type wines obtained by addition of hydroalcoholic plants macerates + other ingredients (citric acid, alcohol, sugar, presented harmonious sensory characteristics, balanced, discreet, subtle, compared with flavored wines obtained only by the addition of hydroalcoholic plants macerates to the basic wines. The latter had a color, aroma, taste, smell, more intense, more rustic. Herbal recipes I B and II B (prepared in 60% alcohol, have strongly influenced the sensory properties of flavored wines, compared to recipes I A and II A (prepared in 45% alcohol.

  16. Egyptian Mythological Manuals

    DEFF Research Database (Denmark)

    Jørgensen, Jens Kristoffer Blach

    From the hands of Greek mythographers a great number of myths have survived along with philosophical discussions of their meaning and relevance for the Greeks. It is little known that something similar existed in ancient Egypt where temple libraries and archives held scholarly literature used...... by the native priesthood, much of which has only been published in recent years. As part of this corpus of texts, the ancient Egyptian mythological manuals offer a unique perspective on how the Egyptian priesthood structured and interpreted Egyptian myths. The thesis looks at the different interpretative...... techniques used in the Tebtunis Mythological Manual (Second century CE) and the Mythological Manual of the Delta (Sixth century BCE) and the place of these manuals within the larger corpus of priestly scholarly literature from ancient Egypt. To organize the wealth of local myths the manuals use model...

  16. Red wines good, white wines bad?

    International Nuclear Information System (INIS)

    Van Velden, D.P.; Mansvelt, E.P.G.; Troup, G.J.

    2002-01-01

    Full text: In 1994, free radicals were discovered in red wines, but only in whites exposed to skins and seeds, and/or oak. The radicals are on the phenolics, and therefore a measure of phenolic content. In 1995, Fuhrman, Levy and Aviram published a study showing antioxidant effects of red wine in the standard Israeli diet, but pro-oxidant effects of the white wine used. No phenolic analysis was done, but low or no phenolics were suspected. Letters to the winery used by Aviram proved fruitless. In 2001, Aviram admits that to see a significant antioxidant effect from white wine, he must make his own, giving it skin and seed contact, and adding alcohol to the fermenting stage, to leach out more tannin from the seeds. This would be unsaleable as a table wine, but not as a 'fortified' or 'dessert' wine. A completely independent study by van Velden in South Africa, with phenol analysis of wines, shows pro- oxidant behaviour of white wines low or lacking in phenolic content. This will be summarised. A Japanese study of the antioxidant properties of some wines shows none for wines low or lacking in catechin content. In the 1950's, two similar but independent studies on different laboratory animals showed no ill effects from 10% alcohol red wine in their diet, but serious effects from 10% pure alcohol - water mix. Conclusion. Drinking only of white wines lacking in phenols, either due to 'fining', or to deliberate avoidance in making, at the recommended 'moderate' drinking level, may be deleterious to cardiovascular health, because of their pro-oxidant action, now established

Although the herbal medicines they produce do not provide a cure for HIV/AIDS, they do offer relief for some of the symptoms of opportunistic infections. The herbs are prepared by the group members under the supervision of the pharmacy department at the district hospital. Local people judge their effectiveness by hearing testimonials from people who have witnessed improvement in symptoms. In response to the popularity and effectiveness of herbal medicines, the Ministry of Public Health has approved plans to sell products derived from local herbs in the pharmacies of government hospitals.

    Full Text Available Donatella Cinelli Colombini Orcia Doc Wine Consortium, Rocca d’Orcia , Italy Abstract: This text includes the history of wine tourism in Italy since 1993, when the first edition of the event “Cantine Aperte” (Open Cellars, Wine Day, took place. The movement grew from the initial 25 wineries to the 21,000 that participate today in opening their doors to the public, while visitors grew in numbers from a couple of hundred, 20 years ago, to the current 4 to 6 million. Wine tourists can be divided into four main groups: wine tourists by chance, classic wine tourists, talent scouts, and lovers of luxury. Each group is examined according to its consumption, its conduct, and its expectations. Wine tourism in Italy boasts around 170 territorial networks: “Strade del Vino” (wine routes regulated by law. After an initial pioneer phase during which preexisting wineries adapted to the growing number of tourists, modern-day wineries were created with bespoke areas for the welcoming of visitors. Wineries in Italy can be classified into the following main types: “functional wineries” that concentrate on productive efficiency; “cathedrals” – renovated historic buildings or modern “starchitecture” designs in which esthetics play an important role; wineries with a “strong identity” linked to the owner or wine producer with the special imprint of his or her personal wine making passion. Other features of Italian wine territories such as food and wellness centers not to speak of the ever present cultural heritage also play a part in attracting wine tourists. Lastly, an evaluation is made of business and communication aspects with a specific reference to the use of the web. Keywords: wine tourism, Italian wineries, winery tours, wine roads of Italy

    Full Text Available Having reviewed a variety of approaches to understanding the essence of wine industry, having studied the modern ideas about the future of wine industry, having analyzed more than 50 maps from the Internet we have set the trends and special features of wine industry mapping in the world, such as: - the vast majority of maps displays the development of the industry at regional or national level, whereas there are practically no world maps; - wine-growing regions are represented on maps very unevenly; - all existing maps of the industry could be classified as analytical ascertaining inventory type; - the dominant ways of cartographic representation are area method and qualitative background method, sign method and collation maps are rarely used; - basically all the Internet maps have low quality as they are scanned images with poor resolution; - the special feature of maps published lately is lack of geographical basis (except for state borders and coastline. We created wine production and consumption world map «Wine Industry» in the scale of 1:60 000 000 with simple geographical basis (state names, state borders, major rivers, coastline. It was concluded that from the methodological point of view it is incorrect not to show geographical basis on maps of wine industry. Analysis of this map allowed us to identify areas of traditional wine-making, potential wine-making areas and countries which claim to be the world leaders in the field of wine production. We found disbalans between wine production and wine consumption - increasing wine production in South America, China and the United States and increasing wine consumption (mainly due to the import products in countries where the grape is not the primary agricultural product.

    1999-01-01

    In ancient Egypt during the reign of Pharaoh Djoser, circa 2650 BC, the Step Pyramid was constructed by Imhotep. He was later worshiped as the God of Medicine. One of his contemporaries was the powerful writer Hesy who is reproduced on a panel showing a rebus of a swallow, a tusk and an arrow. He is therefore looked upon as being the first depicted odontologist. The art of writing begun in Egypt in about 3100 BC and the medical texts we know from different papyri were copied with hieratic signs around 1900-1100 BC. One of the most famous is the Papyrus Ebers. It was purchased by professor Ebers on a research travel to Luxor in 1873. Two years later a beautiful facsimile in color was published and the best translation came in 1958 in German. The text includes 870 remedies and some of them are related to teeth and oral troubles like pain in the mouth, gingivitis, periodontitis and cavities in the teeth. The most common oral pain was probably pulpitis caused by extreme attrition due to the high consumption of bread contaminated with soil and/or quern minerals. Another text is the Papyrus Edwin Smith with four surgical cases of dental interest. The "toothworms" that were presumed to bring about decayed teeth have not been identified in the medical texts. It was not until 1889 W.D. Miller presented a scientific explanation that cavities were caused by bacteria. In spite of extensive research only a few evidence of prosthetic and invasive treatments have been found and these dental artifacts have probably been made post mortem. Some of the 150 identified doctors were associated with treatments of disorders of the mouth. The stele of Seneb from Sa'is during the 26th dynasty of Psamtik, 664-525 BC, shows a young man who probably was a dental healer well known to Pharaoh and his court. Clement of Alexandria mentions circa 200 AD that the written knowledge of the old Egyptians was gathered in 42 collections of papyri. Number 37-42 contained the medical writings. The

  6. Wine and endothelial function.

    Caimi, G; Carollo, C; Lo Presti, R

    2003-01-01

    In recent years many studies have focused on the well-known relationship between wine consumption and cardiovascular risk. Wine exerts its protective effects through various changes in lipoprotein profile, coagulation and fibrinolytic cascades, platelet aggregation, oxidative mechanisms and endothelial function. The last has earned more attention for its implications in atherogenesis. Endothelium regulates vascular tone by a delicate balancing among vasorelaxing (nitric oxide [NO]) and vasoconstrincting (endothelins) factors produced by endothelium in response to various stimuli. In rat models, wine and other grape derivatives exerted an endothelium-dependent vasorelaxing capacity especially associated with the NO-stimulating activity of their polyphenol components. In experimental conditions, reservatrol (a stilbene polyphenol) protected hearts and kidneys from ischemia-reperfusion injury through antioxidant activity and upregulation of NO production. Wine polyphenols are also able to induce the expression of genes involved in the NO pathway within the arterial wall. The effects of wine on endothelial function in humans are not yet clearly understood. A favorable action of red wine or dealcoholized wine extract or purple grape juice on endothelial function has been observed by several authors, but discrimination between ethanol and polyphenol effects is controversial. It is, however likely that regular and prolonged moderate wine drinking positively affects endothelial function. The beneficial effects of wine on cardiovascular health are greater if wine is associated with a healthy diet. The most recent nutritional and epidemiologic studies show that the ideal diet closely resembles the Mediterranean diet.

  7. WINE MARKETS IN CENTRAL EUROPE

    Directory of Open Access Journals (Sweden)

    2007-04-01

    Full Text Available This paper analyses the tendencies of grapes growing, wine trading and wine price competitiveness in Central European region. Croatia is net exporter of wines, Hungary is net exporter of grapes and wines, and Austria, Slovakia, and Slovenia are net importers of grapes and wines. Reductions in vineyards and increase in yields are found for Austria, Hungary, and Slovakia. More stable developments in vineyards, but decline in yields, are found for Croatia and Slovenia. Grape production increases in Austria, remains stable in Croatia, explores annual oscillations in Hungary, and declines in Slovakia and Slovenia. Export-to-import wine prices deteriorate for Austria and Hungary with most recent stabilization and price similarity, which hold also for Slovakia. Slovenian export-to-import wine prices are unstable, while Croatia experiences a bit higher export than import wine prices. Wine marketing, wine brand image of quality, and wine tourism are seen as tools to improve competitiveness in the wine sector.

  12. The Marskhod Egyptian Drill Project

    Science.gov (United States)

    Shaltout, M. A. M.

    We describe a possible participation of Egypt in a future Mars rover Mission. It was suggested that Egypt participate through involvement in the design, building and testing of a drill to obtain sub-surface samples. The Space Research Institute of the Russian Academy of Sciences (IKI), formally invited the Egyptian Ministry of Scientific Research to study the concept for potential use on the Russian Mars 2001 Mission. As one of the objectives of the Marskhod mission was the analysis of sub-surface samples, a drilling mechanism in the payload would be essential. The Egyptian expertise in drill development is associated with the archaeological exploration of the Pyramids. A sophisticated drilling system perforated limestone to a depth of 2 m without the use of lubricants or cooling fluids that might have contaminated the Pit's environment. This experience could have been applied to a drill development Mars 2001 mission, which was unfortunately canceled due to economic problems.

    2017-09-01

    Wine mouthfeel is considered important for wine quality by experts, while consumers understanding of mouthfeel and the role of wine body in their wine choice is unknown. One experiment determined the influence of intrinsic wine mouthfeel on consumers' wine liking and emotions, and the other, how consumers understand the term wine body. The first experiment used a 2 astringency level×2 body level experimental design. The samples were base wine with; nothing added (control), added xanthan gum (for increased body), added grape seed extract (GSE, for increased astringency), and with both added xanthan gum and GSE. The consumer taste trial (n=112) indicated that wine with increased body did not influence wine liking and emotions; while increased astringency decreased liking and elicited more intense negative emotions. The second experiment examined consumers' knowledge of wine body through an online survey (n=136). Consumers described wine body most frequently using words such as flavour, fullness, and strength. Wine body was therefore understood by consumers predominantly as a holistic multi-sensory perception of flavour. Wine flavour was indicated by consumers to be the most important factor driving purchase decisions followed by balance of flavours and wine body. It is crucial that wine professionals carefully communicate wine characteristics to consumers to prevent possible misunderstandings such as the meaning of wine body and as a result better meet consumer expectations. In future, the term body may benefit from a clearer definition for academic research as well as industry. Copyright © 2017. Published by Elsevier Ltd.

    2014-09-01

    Medicine and literature have been linked from ancient times; proof of this shown by the many doctors who have made contributions to literature and the many writers who have described medical activities and illnesses in their works. An example is The Egyptian, the book by Mika Waltari that provides a masterly narration of the protagonist's medical activity and describes the trepanation technique. The present work begins with the analysis of trepanations since prehistory and illustrates the practice of the trepanation in The Egyptian. The book mentions trepanation frequently and illustrates how to practice it and which instruments are required to perform it. Trepanation is one of the oldest surgical interventions carried out as treatment for cranial trauma and neurological diseases, but it also had the magical and religious purpose of expelling the evil spirits which caused the mental illness, epilepsy, or migraine symptoms. Trepanation is a surgical practice that has been carried out since prehistory to treat post-traumatic epilepsy, migraine, and psychiatric illness. The Egyptian is a book that illustrates the trepan, the trepanation technique, and the required set of instruments in full detail. Copyright © 2010 Sociedad Española de Neurología.

    2015-04-01

    Full Text Available Constipation is characterized by a variety of bowel symptoms such as difficulty passing stool, hard stool, and a feeling of incomplete evacuation. The multifactorial causes of constipation limit the clinical efficacy of current conventional treatments that use a single drug that acts through only one pathway. To complement the shortcomings of the current Western medical model and provide a complete holistic approach, herbal medicines capable of targeting multiple organs and cellular sites may be used. In Japan, many herbs and herbal combinations have traditionally been used as foods and medicines. Currently, Japanese physicians use standardized herbal combinations that provide consistent and essential quality and quantity.This review highlights representative Japanese herbal medicines (JHMs, Rhei rhizoma-based JHMs including Daiokanzoto and Mashiningan, and Kenchuto-based JHMs including Keishikashakuyakuto and Daikenchuto, which coordinate the motility of the alimentary tract. This review provides a framework to better understand the clinical and pharmacological efficacies of JHMs on constipation according to the unique theory of Japanese traditional medicine, known as Kampo medicine.

    Kilmartin, Paul A

    2010-01-01

    Microoxygenation (MOX) is now widely applied for the maturation of red wines as an alternative to barrel aging. The proposed improvements in wine quality arising from MOX include color stabilization, removal of unwanted off-odors, and improvements in wine mouthfeel. In this review, an outline is provided of oxygenation systems, particularly microbullage and polymer membrane delivery, and of the current understanding of wine oxidation processes. A summary of the results from published studies into red wine MOX is then provided, beginning with observations on O(2) and acetaldehyde accumulation, and the moderating effect of added sulfur dioxide. Effects upon red wine color, particularly the more rapid formation of polymeric pigments and higher color retention, have been consistently demonstrated in MOX studies, along with further effects on specific polyphenol compounds. A few reports have recently examined the effect of MOX on red wine aromas, but these have yet to identify compounds that consistently change in a manner that would explain sensory observations regarding a lowering of herbaceous and reductive odors. Likewise, tannin analyses have been undertaken in several studies, but explanations of the decline in wine astringency remain to be developed. The accelerated growth of unwanted microorganisms has also been examined in a limited number of studies, but no major problems have been identified in this area. Copyright © 2010 Elsevier Inc.

    Chinese herbal medicine has been practiced for the prevention, treatment, and cure of diseases for thousands of years. Herbal medicine involves the use of natural compounds, which have relatively complex active ingredients with varying degrees of side effects. Some of these herbal medicines are known to cause nephrotoxicity, which can be overlooked by physicians and patients due to the belief that herbal medications are innocuous. Some of the nephrotoxic components from herbs are aristolochic acids and other plant alkaloids. In addition, anthraquinones, flavonoids, and glycosides from herbs also are known to cause kidney toxicity. The kidney manifestations of nephrotoxicity associated with herbal medicine include acute kidney injury, CKD, nephrolithiasis, rhabdomyolysis, Fanconi syndrome, and urothelial carcinoma. Several factors contribute to the nephrotoxicity of herbal medicines, including the intrinsic toxicity of herbs, incorrect processing or storage, adulteration, contamination by heavy metals, incorrect dosing, and interactions between herbal medicines and medications. The exact incidence of kidney injury due to nephrotoxic herbal medicine is not known. However, clinicians should consider herbal medicine use in patients with unexplained AKI or progressive CKD. In addition, exposure to herbal medicine containing aristolochic acid may increase risk for future uroepithelial cancers, and patients require appropriate postexposure screening.

    2001-03-01

    Alexithymia is thought of as a trait that predisposes to drug abuse. Moreover, it is suggested to be related to type of the substance abused, with the worst-case scenario including a worse prognosis as well as tendency to relapse or even not to seek treatment at all. To address this important subject in Egyptian patients, a sample of 200 Egyptian substance abusers was randomly selected from inpatients in the Institute of Psychiatry, Ain Shams University, Egypt. The study also included 200 group-matched controls. DSM-IV criteria were used for assessment of substance use disorders, and toxicologic urine analysis was used to confirm the substances of abuse. Toronto Alexithymia Scale (TAS)-Arabic version was used for assessment of alexithymia. It was found that alexithymia was significantly more prevalent in the substance use disorders group as compared to healthy controls. It was also found that among the substance use disorders group, alexithymics reported more polysubstance abuse, more opiate use (other than heroin IV), lower numbers of hospitalizations, lower numbers of reported relapses, and a lower tendency to relapse as a result of internal cues compared to patients without alexithymia. Statistically significant associations were also found between alexithymia and more benzodiazepine abuse and nonpersistence in treatment. The results suggest that alexithymia should be targeted in a treatment setting for substance use disorders.

    Full Text Available The aging of wine requires a long time therefore it can cause loss of time and money. Therefore using of new techniques for wine aging shortens the length of aging time and wines may be placed on the market more quickly. Nowadays, gamma irradiation, ultrasonic waves, AC electric field and micro-oxygenation are the new techniques for wine aging. Gamma irradiation (after fermentation is accelerated physical maturation method. Gamma irradiation, in a suitable dosage (200 Gy, is a suitable method for improving some wine defects and producing a higher taste quality in wine. The 20 kHz ultrasonic waves aged wine much more quickly than standard aging, with similar quality. The wine treated by 20 kHz ultrasonic waves had a taste equivalent to 1 year aged wine. Wine maturing with AC electric field promises novel process accelerating aging process of fresh wine when suitable conditions are applied. As a result of research, an optimum treatment (electric field 600 V/cm and duration time 3 min was identified to accelerate wine aging. Harsh and pungent raw wine become harmonious and dainty. This process is equivalent to 6 month aging in oak barrel. Microoxygenation is a very important technique used in aging wines in order to improve their characteristics. The techniques of wine tank aging imply the use of small doses of oxygen (2 ml L−1 month−1 and the addition of wood pieces of oak to the wine. Studies concerning these new techniques demonstrated that maturation of wines become more quickly than standard maturation procedures with keeping and improving the wine quality.

  8. Calcium isotopes in wine

    Science.gov (United States)

    Holmden, C. E.

    2011-12-01

    The δ 44/40Ca values of bottled wine vary between -0.76% to -1.55% on the seawater scale and correlate weakly with inverse Ca concentration and Mg/Ca ratio, such that the lowest δ 44/40Ca values have the highest Ca concentrations and lowest Mg/Ca ratios. The correlation is notable in the sense that the measured wines include both whites and reds sampled from different wine growing regions of the world, and cover a wide range of quality. Trends among the data yield clues regarding the cause of the observed isotopic fractionation. White wines, and wines generally perceived to be of lower quality, have lower δ 44/40Ca values compared to red wines and wines of generally perceived higher quality. Quality was assessed qualitatively through sensory evaluation, price, and scores assigned by critics. The relationship between δ 44/40Ca and wine quality was most apparent when comparing wines of one varietal from one producer from the same growing region. In the vineyard, wine quality is related to factors such as the tonnage of the crop and the ripeness of the grapes at the time of harvesting, the thickness of the skins for reds, the age of the vines, as well as the place where the grapes were grown (terroir). Quality is also influenced by winemaking practices such as fermentation temperature, duration of skin contact, and barrel ageing. Accordingly, the relationship between δ 44/40Ca and wine quality may originate during grape ripening in the vineyard or during winemaking in the cellar. We tested the grape ripening hypothesis using Merlot grapes sampled from a vineyard in the Okanagan, British Columbia, using sugar content (degrees Brix) as an indicator of ripeness. The grapes were separated into pulp, skin, and pip fractions and were analyzed separately. Thus far, there is no clear evidence for a systematic change in δ 44/40Ca values associated with progressive ripening of grapes in the vineyard. On the day of harvesting, the δ 44/40Ca value of juice squeezed from

    A sensitive method for evaluating the tritium content in wine and wine yeast was applied to estimate tritium impact on the environment in the surrounding area of nuclear power plant Cernavoda, where the vineyards are part of representative agricultural ecosystem. Analytical procedures were developed to determine HTO in wine and wine yeast samples. The content of organic compounds affecting the LSC measurement is reduced by fractionating distillation for wine samples and azeotropic distillation followed by fractional distillation for wine yeast samples. Finally, the water samples obtained after fractional distillation were normally distilled with KMO 4 . The established procedures were successfully applied for wine and wine yeast samples from Mulfatlar harvests of the years 1995 and 1996. (authors)

The umami taste has distinctive properties that differentiate it from other tastes, including a taste-enhancing synergism between two umami compounds, L-glutamate and 5’-ribonulceotides, and a prolonged aftertaste. In human taste cells, taste buds transduce the chemicals that elicit the umami tastes into membrane depolarization, which triggers release of transmitter to activate gustatory afferent nerve fibers. Umami taste stim...

    Full Text Available The paper develops a study on the Romanians’ attitudes towards the organic wines. The analysis has been done in two stages – at a quantitative level and a qualitative one. The quantitative study has been done on a sample of 122 respondents – consumers and non-consumersin low percentage. The questionnaire investigated the general perception of wines, and included a dedicated section for the organic wines, addressed to the respondents aware of this product.The qualitative stage has been realized through a sensorial analysis, where three white wines and two red wines have been tasted by trained tasters. Among the five wines, one white – Chardonnay was organicwine. Both studies proved that the organic wine has a potential in Romania due to the sensorial qualities and people’s perception. However, the development of organic wine market won’t be a quick process and it will require first of all improving Romanians’ ‘organic’ culture.

    Lozano, J.; Santos, J. P.; Horrillo, M. C.; Cabellos, J. M.; Arroyo, T.

    2009-01-01

    An electronic nose installed in a wine cellar for measuring the wine evolution is presented in this paper. The system extract the aroma directly from the tanks where wine is stored and carry the volatile compounds to the sensors cell. A tin oxide multisensor, prepared with RF sputtering onto an alumina substrate and doped with chromium and indium, is used. The whole system is fully automated and controlled by computer and can be supervised by internet. Linear techniques like principal component analysis (PCA) and nonlinear ones like probabilistic neural networks (PNN) are used for pattern recognition. Results show that system can detect the evolution of two different wines along 9 months stored in tanks. This system could be trained to detect off-odours of wine and warn the wine expert to correct it as soon as possible, improving the final quality of wine.

  10. [Eulogy of wine?].

    In the literature the beneficial effects on health of drinking alcoholic beverages, especially red wine, is becoming increasingly more evident. We report an objective analysis of the advantages and the dangers of such a tendency. It appears that the daily consumption of red wine at moderate doses (200-400 ml a day) has real prophylactic effects. These are particularly marked in the prevention of coronary heart disease (CHD), but also for a possible cancer chemopreventive activity, in the prevention of type II diabetes, of ischemic stroke, of osteoporosis in older women, and of Alzheimer's disease. But, inasmuch as the consumption of alcoholic beverages always involves a potential danger (organic diseases, risk of dependence, alcoholism), from a medical point of view eulogy to wine is ethically indefensible. Similar effects may be obtained from a diet rich in fruits and fresh vegetables.

  11. Relationship between Menthiafolic Acid and Wine Lactone in Wine.

    Giaccio, Joanne; Curtin, Chris D; Sefton, Mark A; Taylor, Dennis K

    2015-09-23

    Menthiafolic acid (6-hydroxy-2,6-dimethylocta-2,7-dienoic acid, 2a) was quantified by GC-MS in 28 white wines, 4 Shiraz wines, and for the first time in 6 white grape juice samples. Menthiafolic acid was detected in all but one of the wine samples at concentrations ranging from 26 to 342 μg/L and in the juice samples from 16 to 236 μg/L. Various model fermentation experiments showed that some menthiafolic acid in wine could be generated from the grape-derived menthiafolic acid glucose ester (2b) during alcoholic and malolactic fermentation. Samples containing high concentrations of menthiafolic acid were also analyzed by enantioselective GC-MS and were shown to contain this compound in predominantly the (S)-configuration. Enantioselective analysis of wine lactone (1) in one of these samples, a four-year-old Chardonnay wine showed, for the first time, the presence of the 3R,3aR,7aS isomer of wine lactone (1b), which is the enantiomer of the form previously reported as the sole isomer present in young wine samples. The weakly odorous 3R,3aR,7aS 1b form comprised 69% of the total wine lactone in the sample. On the basis of the enantioselectivity of the hydrolytic conversion of menthiafolic acid to wine lactone at pH 3.0 determined previously and the relative proportions of (R)- and (S)-menthiafolic acid in the Chardonnay wine, the predicted ratio of wine lactone enantiomers that would be formed from hydrolysis at ambient temperature of the menthiafolic acid present in this wine was close to the ratio measured, which was consistent with menthiafolic acid being the major or sole precursor to wine lactone in this sample.

    Full Text Available Ildikó Magyar, János Soós Department of Oenology, Institute of Viticulture and Oenology, Szent István University, Budapest, Hungary Abstract: Botrytized wines are wine specialties made of overripe grapes infected by Botrytis cinerea with the form “noble rot”. Due to the particular characteristics of the noble rotted grape, these wines (eg, Tokaji Aszú, Sauternes, Trockenbeerenauslese types, etc have many characteristic features, including higher or lower residual sugar content and unique aroma composition. The technology, biochemistry, and special characteristics of botrytized wines have been researched for a long time. This review outlines the main directions of the current studies, giving a brief overview on the recent findings. Beside the traditional wine types, noble rot is increasingly utilized in making newer sweet wine styles and straw (passito wines, which generates a series of new interesting experimental results. The fungus–grape interactions during the noble rot, the induced botrytization, the microbial communities of botrytized wines, and the volatile compounds having key roles in the distinct aroma of these wine styles are being focused on in the current studies in this field.

    Shinde, Devanand B.; Chavan, Machindra J.; Wakte, Pravin S.

    For the past few decades, compounds from natural sources have been gaining importance because of the vast chemical diversity they offer. This has led to phenomenal increase in the demand for herbal medicines in the last two decades and need has been felt for ensuring the quality, safety, and efficacy of herbal drugs. Phytochemical evaluation is one of the tools for the quality assessment, which include preliminary phytochemical screening, chemoprofiling, and marker compound analysis using modern analytical techniques. High-performance thin-layer chromatography (HPTLC) has been emerged as an important tool for the qualitative, semiquantitative, and quantitative phytochemical analysis of the herbal drugs and formulations. This includes developing TLC fingerprinting profiles and estimation of biomarkers. This review has an attempt to focus on the theoretical considerations of HPTLC and some examples of herbal drugs and formulations analyzed by HPTLC.

    Koike, Takayuki; Kamimura, Hironobu; Shimada, Kouji; Yamada, Hiroshi; Kaneki, Noriaki

    The decision to choose the appropriate product matching the preference of each individual is based on the psychological impression of the adjective and the alternatives. The preference for a product group and physical condition also affect decision-making. The purpose of this study was to investigate the influence of differences in the preference of wine and changes in hunger level on the psychological and neuro-physiological aspects of decision-making where the subjects were asked to choose their most favorite wine after sniffing the aroma of several wines. The psychological aspects of decision-making while sniffing five different kinds of wine were evaluated by the analytical hierarchal process (AHP) method, while the neuro-physiological aspects were evaluated by measuring the level of oxygenated hemoglobin concentrations (O2Hb) in the process of smelling the wine aromas within three minutes compared to when the non-odor and alcoholic solutions were presented. AHP analysis showed that the adjective “Favorite” was given the highest importance and a white wine with a sweet aroma was the most favored wine, regardless of the wine preference. The normalized mean O2Hb levels in each minute showed that, in the case of the wine lovers, the time course of the O2Hb level, decreased when they sensed the wine aroma compared to when they sensed non-odor solutions, and, in non-wine lovers, the O2Hb levels remained at higher values compared to the smell of the non-odor solution when they sensed the aroma of the alcoholic solution. The results indicate that there are differences with regard to decision-making between the psychological and physiological aspects when people are made to choose their most favorite wine by sniffing wine aromas.

  20. Does wine prevent dementia?

    Directory of Open Access Journals (Sweden)

    Roger M Pinder

    2009-02-01

    Full Text Available Roger M PinderPharma Consultant, York, UKAbstract: There is substantial evidence that moderate consumption of alcohol reduces significantly the risks of coronary heart disease, stroke and type 2 diabetes. Furthermore, the incidence of dementia, both of the Alzheimer’s type (AD and the vascular variety (VaD, is lower in societies which consume a Mediterranean diet of mainly fish, fruit, vegetables, olive oil, and wine. In particular, extensive evidence from both population-based cohort and case control studies in different areas of the world and across genders and racial groups suggests that regular consumption of moderate amounts of alcohol, especially in the form of wine, is associated with a lower risk of developing AD and VaD compared with abstention and heavy drinking. Carriers of the APOE ε4 allele seem to gain less benefit. Age-related cognitive decline, particularly in women, is lower in regular drinkers, while older drinkers with Mild Cognitive Impairment (MCI progress less frequently to AD than their abstaining counterparts. Plausible biological mechanisms for the neuroprotective effects of wine include its glucose-modifying, antioxidant and inflammatory properties, but it additionally seems to modify the neuropathology of AD, particularly the deposition of amyloid plaque. Indeed, some of these mechanisms are already targets for the development of new therapeutic agents for the treatment of dementia.Keywords: alcohol, Alzheimer’s disease, dementia, epidemiology, polyphenols, wine

    The term "paranatellonta" is well-known in greek astrological literature. It designates stars either rising together with the sun or being in other conspicuous positions to it. Tentatively, a forerunner of this conception is identified in an egyptian depiction attested several times from the 13th century BC onwards. There, "gods" are depicted who are defined by their positions in regard to the sun-god. It seems possible to connect their positions with the typical meanings of the word paranatellonta. Some reflections on the contribution of Egypt to hellenistic astrology are added, including some references to the largely unpublished corpus of demotic egyptian astrological texts.

    Directory of Open Access Journals (Sweden)

    Ioannis G. Roussis

    2005-01-01

    Full Text Available The aim of this study was to assess the ability of different wines – a sweet red, a dry red, a sweet white, and a dry white – to scavenge the stable 1,1’-diphenyl-2-picryl-hydrazyl radical (DPPH. and to determine their phenolic composition. Both red wines contained, apart from anthocyanins, also higher concentration of total phenolics, tartaric esters, and flavonols than the two white wines. All wines exhibited scavenging activity analogous to their total phenolic content. However, their phenolics differed in antiradical potency, which was visible in their EC50 values. The dry red wine, Xinomavro, had a lower EC50 value, indicating the higher antiradical potency of its phenolics. The scavenging capacities of phenolic extracts from Xinomavro red wine on hydroxyl radicals, superoxide radicals, and singlet oxygen were also assessed. Wine total extract was fractionated by extraction, and each of the three fractions was then subfractionated by column chromatography into two subfractions. Wine total extract, and its fractions and subfractions exhibited scavenging capacity on hydroxyl radicals, superoxide radicals, and singlet oxygen, indicating the activity of many wine phenolics. The most active wine extracts towards hydroxyl radicals were characterized by the high peaks of flavanols, anthocyanins and flavonols in their HPLC-DAD chromatograms. The most active extract towards superoxide radicals was rich in flavanols and anthocyanins. The characteristic phenolics of the most active wine extracts towards singlet oxygen were flavanols, flavonols and phenolic acids. The ability of all red wine phenolic extracts to scavenge singlet oxygen, along with hydroxyl and superoxide radicals, emphasizes its health functionality.

    Hyperthyroidism is a disease in which excessive amounts of thyroid hormones circulate in the blood. Patients, among other things suffer from tachycardia, warm moist skin and raised body temperature. The treatment of hyperthyroidism includes symptom relief and therapy with antithyroid medications, radioiodine and thyroidectomy. Medicinal herbs are used alone or in combination with antithyroid agents to treat hyperthyroidism in China and some other countries. To assess the effects of Chinese herbal medicines for treating hyperthyroidism. Studies were obtained from computerised searches of MEDLINE, EMBASE, The Cochrane Library, the Chinese Biomedical Database. Randomised controlled trials comparing the effects of Chinese herbal medicines alone with Chinese herbal medicines combined with antithyroid drugs, radioiodine or both. Three authors interviewed authors of all potentially relevant studies by telephone to verify randomisation procedures. One author entered data into a data extraction form and another author verified the results of this procedure. Thirteen relevant trials with 1770 participants were included. All of them were of low quality. Fifty-two studies still need to be assessed because the original authors could not be interviewed. None of these trials analysed mortality, health related quality of life, economic outcomes or compliance. Compared to antithyroid drugs alone the results showed that Chinese herbal medicines combined with antithyroid drugs may offer benefits in lowering relapse rates, reducing the incidence of adverse effects, relieving symptoms, improving thyroid antibody status and thyroid function. Two trials investigated Chinese herbal medicine versus radioiodine and reported improvements in anxiety, tachycardia and heat intolerance. However, thyroid function - with the exception of restored thyroid stimulating hormone (TSH) - was not significantly altered. The results suggest that traditional Chinese herbal medicines added to other routine

As consumer environmental knowledge of a wine tourism destination increases, consumer attitudes change, influencing perceptions of the environmental policies of a wine region. In this consumer-driven economy, it is therefore important to search for effective ways to market destinations, and one approach is selective marketing. By focusing on consumers in this manner, it is possible to understand better their concerns and motivations, which should aid in marketing and advertising efforts. This study investigated wine consumers environmental concerns and attitudes about wine regions. Results suggest environmental attitudes differed by demographics regarding the impact of wine tourism, providing ideas on further marketing efforts for those involved in wine tourism.Keywords: sustainable wine tourism, green products, wine marketing, consumers

    The study of acetabular morphology has shown that there are geographic differences in the morphology and prevalence of acetabular dysplasia among different ethnic groups. However, few data exist on the shape of the acetabulum in various populations around the world. In this study, we examined samples of pelvic radiographs from Egyptian adults. Acetabular dysplasia in adults is characterized by a shallow and relatively vertical acetabulum.The aim of this study was to examine acetabular morphology to determine the prevalence of hip dysplasia in adult Egyptians. This included 244 adults, 134 men and 110 women between 18 and 60 years, who were used to measure center edge angle, acetabular Sharp angle, acetabular head index on anteroposterior radiographic views of the hip joints, and vertical center anterior margin angle on false profile views. The radiographs were taken of patients with no hip complaints at Tanta University Hospital.The results were statistically studied according to the age, height, and weight of patients. The prevalence of acetabular dysplasia was 2.25% for Egyptian men and 3.6% for women with respect to center edge angles, vertical center anterior margin angle, and acetabular head index.We concluded that gender variations in the morphology of the acetabulum and sex influences geometrical measurements of the acetabulum. Egyptian women were more dysplastic than men using the 4 parameters of hip measurements. There are also racial variations in hip morphology. Copyright 2011, SLACK Incorporated.

    Egypt is famously known for its Nile and pyramids, yet not many people know that Egypt made possible the origin of the anatomical sciences. Several ancient papyri guide us through the Egyptians' exploration of the human body and how they applied anatomical knowledge to clinical medicine to the best of their knowledge. It is through records, such as the Edwin Smith, Ebers, and Kahun papyri and other literature detailing the work of the Egyptian embalmers, physicians, and Greek anatomists, that we are able to take a glimpse into the evolution of the anatomical sciences from 3000 B.C. to 250 B.C. It is through the Egyptian embalmer that we were able to learn of some of the first interactions with human organs and their detailed observation. The Egyptian physician's knowledge, being transcribed into the Ebers and Edwin Smith papyri, enabled future physicians to seek reference to common ailments for diagnosing and treating a variety of conditions ranging from head injuries to procedures, such as trans-sphenoidal surgery. In Alexandria, Herophilus, and Erasistratus made substantial contributions to the anatomical sciences by beginning the practice of human dissection. For instance, Herophilus described the anatomy of the heart valves along with Erasistratus who demonstrated how blood was prevented from flowing retrograde under normal conditions. Hence, from various records, we are able to unravel how Egypt paved the road for study of the anatomical sciences. Copyright © 2011 Wiley-Liss, Inc.

    Quality and safety of food and herbal supplements are the result of a whole of different elements as good manufacturing practice and process control. The process control must be active and able to individuate and correct all possible hazards. The main and most utilized instrument is the hazard analysis critical control point (HACCP) system the correct application of which can guarantee the safety of the product. Herbal supplements need, in addition to standard quality control, a set of checks to assure the harmlessness and safety of the plants used.

  4. Wine Expertise Predicts Taste Phenotype.

    Hayes, John E; Pickering, Gary J

    2012-03-01

    Taste phenotypes have long been studied in relation to alcohol intake, dependence, and family history, with contradictory findings. However, on balance - with appropriate caveats about populations tested, outcomes measured and psychophysical methods used - an association between variation in taste responsiveness and some alcohol behaviors is supported. Recent work suggests super-tasting (operationalized via propylthiouracil (PROP) bitterness) not only associates with heightened response but also with more acute discrimination between stimuli. Here, we explore relationships between food and beverage adventurousness and taste phenotype. A convenience sample of wine drinkers (n=330) were recruited in Ontario and phenotyped for PROP bitterness via filter paper disk. They also filled out a short questionnaire regarding willingness to try new foods, alcoholic beverages and wines as well as level of wine involvement, which was used to classify them as a wine expert (n=110) or wine consumer (n=220). In univariate logisitic models, food adventurousness predicted trying new wines and beverages but not expertise. Likewise, wine expertise predicted willingness to try new wines and beverages but not foods. In separate multivariate logistic models, willingness to try new wines and beverages was predicted by expertise and food adventurousness but not PROP. However, mean PROP bitterness was higher among wine experts than wine consumers, and the conditional distribution functions differed between experts and consumers. In contrast, PROP means and distributions did not differ with food adventurousness. These data suggest individuals may self-select for specific professions based on sensory ability (i.e., an active gene-environment correlation) but phenotype does not explain willingness to try new stimuli.

  8. The health benefits of wine.

    2000-01-01

    Epidemiologic studies from numerous disparate populations reveal that individuals with the habit of daily moderate wine consumption enjoy significant reductions in all-cause and particularly cardiovascular mortality when compared with individuals who abstain or who drink alcohol to excess. Researchers are working to explain this observation in molecular and nutritional terms. Moderate ethanol intake from any type of beverage improves lipoprotein metabolism and lowers cardiovascular mortality risk. The question now is whether wine, particularly red wine with its abundant content of phenolic acids and polyphenols, confers additional health benefits. Discovering the nutritional properties of wine is a challenging task, which requires that the biological actions and bioavailability of the >200 individual phenolic compounds be documented and interpreted within the societal factors that stratify wine consumption and the myriad effects of alcohol alone. Further challenge arises because the health benefits of wine address the prevention of slowly developing diseases for which validated biomarkers are rare. Thus, although the benefits of the polyphenols from fruits and vegetables are increasingly accepted, consensus on wine is developing more slowly. Scientific research has demonstrated that the molecules present in grapes and in wine alter cellular metabolism and signaling, which is consistent mechanistically with reducing arterial disease. Future research must address specific mechanisms both of alcohol and of polyphenolic action and develop biomarkers of their role in disease prevention in individuals.

    A population based cohort study investigates the association between alcohol intake and mortality from all causes, coronary heart disease and cancer. The design is prospective with baseline assessment of intake of beer, wine and spirits, smoking habits, educational level, physical activity, and body mass index and a total of 257,859 person-years follow-up on mortality. A total of 4,833 participants died, of these 1,075 from coronary heart disease and 1,552 of cancer. Compared with non-drinkers, light drinkers who avoided wine, had a relative risk of death from all causes of 0.90 (0.82-0.99) and those who drank wine had a relative risk of 0.66 (0.55-0.77). Heavy drinkers who avoided wine were at higher risk of death from all causes than were heavy drinkers who included wine in their alcohol intake. Wine drinkers had significantly lower mortality from both coronary heart disease and cancer than did non-wine drinkers (p = 0.007 and p = 0.004, respectively). In conclusion, wine intake may have a beneficial effect on all cause mortality that is additive to that of alcohol. This effect may be attributable to a reduction in death from both coronary heart disease and cancer.

  12. Technological change in the wine market? The role of QR codes and wine apps in consumer wine purchases

    2014-06-01

    Full Text Available As an experiential good, wine purchases in the absence of tastings are often challenging and information-laden decisions. Technology has shaped the way consumers negotiate this complex purchase process. Using a sample of 631 US wine consumers, this research aims to identify the role of mobile applications and QR codes in the wine purchase decision. Results suggest that wine consumers that consider themselves wine connoisseurs or experts, enjoy talking about wine, and are interested in wine that is produced locally, organically, or sustainably are more likely to employ technology in their wine purchase decision. While disruption appears to have occurred on the supply side (number of wine applications available and the number of wine labels with a QR code, this research suggests that relatively little change is occurring on the demand side (a relatively small segment of the population—those already interested in wine—are employing the technology to aid in their purchase decision.

    Full Text Available In a global world, wineries have to satisfy the demand of consumers who wish to drink high quality wines from countries all over the world. To fulfill this request wines have to be transported, crossing thereby great distances from the place of production to the consumer country. At the Institute of Enology of Hochschule Geisenheim University examinations with White-, Rosé- and Red-Wines of different origins which had been transported over longer distances within Europe (Portugal, France, Italy to Germany by trucks were carried out. Shipping of wines was simulated in a climatized cabinet to analyze the influence on wine quality during this way and conditions of transportation. Time and temperature profiles were based on real transport situtations which were recorded during shipping from Germany to Japan using data loggers. White, Rosé and Red wines were transported during 6 to 8 weeks and then were analytically and sensorically compared to those which were stored at a constant temperature of 15 ∘C. Besides the effect of temperature, the movements and vibrations encountered by the wines were also examined. Analytically wines were analyzed for general analytical parameters with Fourier-Transformation-Infrared-Spectroscopie (FTIR, Colour differences (Spectralphotometrie and free and total sulfuric acid with Flow-Injection-Analysis (FIA. Sensory examinations with a trained panel were performed in difference tests in form of rankings and triangular tests. Summarizing the results from the different tests it could be found that transportation had an influence on the potential ageing of wines depending on the wine matrix. Especially high and varying temperatures during transportations over a longer distance and time had negative influences on wine quality. Also the movement of wine at higher temperatures had showed a negative effect whereas transport at cool temperatures even below 0 ∘C did not influence wine characteristics. Sophisticated

    2015-11-01

    The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field images noninvasively showing the distribution of the pigment on a work of art. A growing body of publications in the last decade highlights the increasing use of this tool and its sensitive detection limits. However, the technique is not wavelength specific. Both excitation and emission occur in a broad range. Although Egyptian blue has a strong emission in the NIR, a myriad of other compounds may emit light in this spectral region when excited in the visible. The limited number of studies including complementary analysis to verify the presence of Egyptian blue does not allow its identification on the basis of NIR luminescence alone. Through the use of in situ X-ray fluorescence and X-ray diffraction, and scanning electron microscopy/energy-dispersive spectroscopy of cross sections, this paper confirms the identification of Egyptian blue by NIR luminescence in unexpected areas, i.e., those not blue in appearance.

    2010-12-01

    Egyptian medicine is the base of Greek medicine. Egyptian people and their medical knowledge are often mentioned in the Iliad and Odyssey of Homer (VIII sec. BCE). Many Greek doctors, such as Melampus, Asclepius as well as Hippocrates visited Egypt to study and understand medicine. This work intends to focus particularly on Homer, Herodotus and Plutarch's letters, where the importance of Egypt in religion, science and medicine is clear. Herodotus (484-420 BCE) in the second book of "The Histories" describes Egypt and the medical knowledge of its doctors. Plutarch (I-II sec CE) in "The virtues of Sparta" and "Life of Lycurgus", tells about an energy beverage, named nepenthe, made with drugs from Egypt.

    2017-07-05

    White wine mouthfeel which encompasses the tactile, chemosensory and taste attributes of perceived viscosity, astringency, hotness and bitterness is increasingly being recognized as an important component of overall white wine quality. This review summarizes the physiological basis for the perception of white wine mouthfeel and the direct and interactive effects of white wine composition, specifically those of low molecular weight phenolic compounds, polysaccharides, pH, ethanol, glycerol, dissolved carbon dioxide, and peptides. Ethyl alcohol concentration and pH play a direct role in determining most aspects of mouthfeel perception, and provide an overall framework on which the other minor wine components can interact to influence white wine mouthfeel. Phenolic compounds broadly impact on the mouthfeel by contributing to its viscosity, astringency, hotness and bitterness. Their breadth of influence likely results from their structural diversity which would allow them to activate multiple sensory mechanisms involved in mouthfeel perception. Conversely, polysaccharides have a small modulating effect on astringency and hotness perception, and glycerol does not affect perceived viscosity within the narrow concentration range found in white wine. Many of the major sensory attributes that contribute to the overall impression of mouthfeel are elicited by more than one class compound suggesting that different physiological mechanisms may be involved in the construct of mouthfeel percepts.

    Bonaparte's Egyptian Campaign (1798 - 1801), like all other episodes from the Napoleonic era, gave rise to an extensive literature on the subject, but most of all a significant medical literature. This fact is due to many reasons:--an important health service for this expeditionary corps of more than 36.000 men, with two main figures at its hea, Desgenettes and Larrey--but also with valuable subordinates like Assalini, Savaresi, Balme, Pugnet or Barbès.--A Commission for Science and Art, of which a few doctors and surgeons were members, but most of all pharmacists like Boudet or Rouyer--The presence in the field of Ludwig Frank, the nephew of the famous Johann Peter Frank.--The creation in Cairo of an Egyptian Institute and the publication of the masterly Description of Egypt and the establishment of printing houses.--The emergence of the myth of the Orient and its mysteries.--An extensive array of indigenous pathologies, which is characteristic of those countries. For instance: plague, dysentery, yellow fever, Egyptian ophthalmia, as well as more common diseases like tetanus, scurvy or venereal diseases. The main medical works that cover this period and its pathologies are skimmed.

  11. Biological Demalication and Deacetification of Musts and Wines: Can Wine Yeasts Make the Wine Taste Better?

    Directory of Open Access Journals (Sweden)

    Alice Vilela

    2017-10-01

    Full Text Available Grape musts sometimes reveal excess acidity. An excessive amount of organic acids negatively affect wine yeasts and yeast fermentation, and the obtained wines are characterized by an inappropriate balance between sweetness, acidity or sourness, and flavor/aroma components. An appropriate acidity, pleasant to the palate is more difficult to achieve in wines that have high acidity due to an excess of malic acid, because the Saccharomyces species in general, cannot effectively degrade malic acid during alcoholic fermentation. One approach to solving this problem is biological deacidification by lactic acid bacteria or non-Saccharomyces yeasts, like Schizosaccharomyces pombe that show the ability to degrade L-malic acid. Excessive volatile acidity in wine is also a problem in the wine industry. The use of free or immobilized Saccharomyces cells has been studied to solve both these problems since these yeasts are wine yeasts that show a good balance between taste/flavor and aromatic compounds during alcoholic fermentation. The aim of this review is to give some insights into the use of Saccharomyces cerevisiae strains to perform biological demalication (malic acid degradation and deacetification (reduction of volatile acidity of wine in an attempt to better understand their biochemistry and enological features.

    2010-01-01

    Plants have been an important source of medicine for thousands of years and herbs are hot currency in the world today. During the last decade, popularity of alternative medicine increased significantly worldwide with noticeable trend. This in turn accelerated the global trade of herbal raw materials and herbal products and created greater scope for Asian countries that possess the major supply of herbal raw materials within their highly diversified tropical rain forest. As such, advanced bioreactor culture system possesses a great potential for large scale production than the traditional tissue culture system. Bioreactor cultures have many advantages over conventional cultures. Plant cells in bioreactors can grow fast and vigorously in shorter period as the culture conditions in bioreactor such as temperature, pH, concentrations of dissolved oxygen, carbon dioxide and nutrients can be optimised by on-line manipulation. Nutrient uptake can also be enhanced by continuous medium circulation, which ultimately increased cell proliferation rate. Consequently, production period and cost are substantially reduced, product quality is controlled and standardized as well as free of pesticide contamination and production of raw material can be conducted all year round. Taking all these into consideration, current research efforts were focused on varying several parameters such as inoculation density, air flow, medium formulation, PGRs etc. for increased production of cell and organ cultures of high market demand herbal and medicinal plants, particularly Eurycoma longifolia, Panax ginseng and Labisia pumila. At present, the production of cell and organ culture of these medicinal plants have also been applied in airlift bioreactor with different working volumes. It is hope that the investment of research efforts into this advanced bioreactor technology will open up a bright future for the modernization of agriculture and commercialisation of natural product.

    2011-03-01

    Full Text Available Within contemporary Western herbal medicine, traditional knowledge and modern science are combined to provide a unique meeting of patient, practitioner and plant. In the Australian context, herbalists have based their practice on knowledge which originates from the traditions of Europe, and has more recently been influenced by traditional medicine from Asia. The combination of these diverse ways of knowing—traditional and modern, Eastern and Western—means herbal practitioners are influenced by ancient philosophy alongside phytochemistry and biomedical sciences. The challenge for herbal medicine today is that faced by all living (as opposed to ossified traditions: how is a practice forged which retains what is valuable from the past while establishing relevance to the 21st century? We illustrate these issues in the context of the conference theme of ‘food for thought’ and consider medicinal plants which are used for the improvement of cognition. We focus on the therapeutic use of common herbs from the Eastern and Western traditions and present the scientific research which shows their ability to facilitate cognitive function and the laying down of memory. We also tell their traditional stories which indicate that these actions have been recognised and utilised for centuries. We go on to demonstrate, via case studies, the clinical application of this knowledge and in particular the importance of ancient practice of synergistic prescribing which occurs when a number of herbs are prescribed together in a formula. Scientific understanding of the basis of this practice is being developed which further complements and validates traditional herbal wisdom.

    2014-06-01

    Full Text Available Marketing has proven to be very useful instrument in the wine industry, in fostering comprehensive, cohesive and effective strategies which wineries require to effectively compete in today’s almost saturated wine market. But within wine marketing, the promotion strategy, from our point of view, is the most important component of the winery that can ensure the success in the market or can shorten the life cycle of the product. This being said, the aim of the paper is twofold. Firstly, to determine and analyze the steps that are required to create a promotion strategy in the wine industry, by comparing different approaches. Secondly, to identify the instruments of the promotional mix that helps a winery to implement its promotional strategy. Bearing that in mind, the paper starts with some theoretical aspects regarding the promotion strategy and ends by providing a brief overview of the main findings.

    2009-12-30

    Herbal antimalarials still remain an alternative to our traditional communities who can not afford orthodox antimalarials. This study was aimed at investigating the microbial quality of six herbal antimalarials using standard microbiological methods. Of the six preparations analyzed, "schnapps", palm wine and water were the media of preparation; the water base preparations recorded higher microbial load. The mean microbial load was 159.5 × 10(5) cfu/ml and 217.4 × 10(2)cfu/ml in water and alcohol base preparations respectively. The microbial profile of the preparations showed that the schnapps base preparations were predominantly contaminated with Bacillus sp (Aerobic spore bearers) and Mucor spp. The palm wine preparation harboured Bacillus sp, yeasts and Mucor spp while the water base preparations had several isolates such as Staphylococcus epidermidis, Pseudomonas aeruginosa, Escherichia coli 0157H7, Proteus mirabilis, Enterococcus feacalis, Serratia marcensces, Staph. aureus, Bacillus spp and Mucor spp. Conclusively, this study underlines the public health importance of these preparations given the high burden of such human pathogen as Ecoli O157H7, Ps aeruginosa, Stahp aureus, etc. in the preparations.

    Full Text Available This study aimed at verifying the presence of variations in the reactions of different types of audiences to certain communication tools for wine. Five samples of audiences were compared: wine professionals, organic produce specialists, wine tourists, and two samples of general tourists. The following bundle of attributes were considered: name of the grape; information on organic production methods; type of closure; QR code; landscape; advertising language. Diverse audience’s preferences were measured by conjoint analysis. The results have shown a common sensitivity to certain attributes, and a different or contrary sensitivity to others. In particular, all samples have demonstrated that: 1 certified organic wines communicated in standard wine-market style have the potential of becoming market leaders; 2 photographs facilitate the acceptance of technologically-advanced closures; 3 the presence of the QR code in printed advertisements increases the expected value of the product; 4a landscape characterised by holistic “garden viticulture” increases preferences. Textual language was more effective with professionals, while photographic language was more effective with tourists. Supplementary information on the organic production methods, in addition to the mandatory labelling requirements, increased the preferences of professionals and wine tourists, and was counterproductive with the general tourists.

  13. Microbial Glycosidases for Wine Production

    Directory of Open Access Journals (Sweden)

    Sergi Maicas

    2016-08-01

    Full Text Available Winemaking is a complex process involving the interaction of different microbes. The two main groups of microorganisms involved are yeasts and bacteria. The yeasts present in spontaneous fermentation may be divided into two groups: the Saccharomyces yeasts, particularly S. cerevisiae; and the non-Saccharomyces yeasts, which include members of the genera Rhodotorula, Pichia, Candida, Debaryomyces, Metschtnikowia, Hansenula, and Hanseniaspora. S. cerevisiae yeasts are able to convert sugar into ethanol and CO2 via fermentation. They have been used by humans for thousands of years for the production of fermented beverages and foods, including wine. Their enzymes provide interesting organoleptic characteristics in wine. Glycosidases with oenological implications have been widely reported in yeasts, bacteria, and fungi. β-Glucosidase activity is involved in the release of terpenes to wine, thus contributing to varietal aroma. α-Rhamnosidase, α-arabinosidase, or β-apiosidase activities have also been reported to contribute to the wine production process. Oenococcus oeni (a lactic acid bacteria present in wine also has numerous glycosidases, and their activities contribute to the liberation of several aromatic compounds which contribute to floral and fruity wine characteristics.

    2013-01-01

    Herbal and dietary supplements are commonly used throughout the World. There is a tendency for underreporting their ingestion by patients and the magnitude of their use is underrecognised by Physicians. Herbal hepatotoxicity is not uncommonly encountered, but the precise incidence and manifestations have not been well characterised. To review the epidemiology, presentation and diagnosis of herbal hepatotoxicity. This review will mainly discuss single ingredients and complex mixtures of herbs marketed under a single label. A Medline search was undertaken to identify relevant literature using search terms including 'herbal', 'herbs', 'dietary supplement', 'liver injury', 'hepatitis' and 'hepatotoxicity'. Furthermore, we scanned the reference lists of the primary and review articles to identify publications not retrieved by electronic searches. The incidence rates of herbal hepatotoxicity are largely unknown. The clinical presentation and severity can be highly variable, ranging from mild hepatitis to acute hepatic failure requiring transplantation. Scoring systems for the causality assessment of drug-induced liver injury may be helpful, but have not been validated for herbal hepatotoxicity. Hepatotoxicity features of commonly used herbal products, such as Ayurvedic and Chinese herbs, black cohosh, chaparral, germander, greater celandine, green tea, Herbalife, Hydroxycut, kava, pennyroyal, pyrrolizidine alkaloids, skullcap, and usnic acid, have been individually reviewed. Furthermore, clinically significant herb-drug interactions are also discussed. A number of herbal medicinal products are associated with a spectrum of hepatotoxicity events. Advances in the understanding of the pathogenesis and the risks involved are needed to improve herbal medicine safety. © 2012 Blackwell Publishing Ltd.

    The objective is to summarize the pattern of Egyptian migration to Arab oil-producing countries (AOPC), to review some factors that are important determinants of labor movement based on theory, and to empirically model the migration rate to AOPC and to Saudi Arabia. Factors are differentiated as to their relative importance. Push factors are the low wages, high inflation rate, and high population density in Egypt; pull factors are higher wages. It is predicted that an increase in income from destination countries has a significant positive impact on the migration rate. An increase in population density stimulates migration. An increase in inflation acts to increase out-migration with a 2-year lag, which accommodates departure preparation. Egypt's experience with labor migration is described for the pre-oil boom, and the post-oil boom. Several estimates of labor migration are given. Government policy toward migration is positive. Theory postulates migration to be determined by differences in the availability of labor, labor rewards between destination and origin, and the cost of migration. In the empirical model, push factors are population density, the current inflation rate, and the ratio of income/capita in AOPC to Egypt. The results indicate that the ratio of income/capita had a strong pull impact and population density had a strong push impact. The inflation rate has a positive impact with a lag estimated at 2 years. Prior to the Camp David Accord, there was a significant decrease in the number of Egyptian migrants due to political tension. The findings support the classical theory of factor mobility. The consequences of migration on the Egyptian economy have been adverse. Future models should disaggregate data because chronic shortages exist in some parts of the labor market. Manpower needs assessment would be helpful for policy makers.

    Passage of the Dietary Supplement Health and Education Act in 1994 restricted the Food and Drug Administration's control over dietary supplements, leading to enormous growth in their promotion. The Internet is often used by consumers as a source of information on such therapies. To assess the information presented and indications claimed on the Internet for the 8 best-selling herbal products. We searched the Internet using the 5 most commonly used search engines. For each, we entered the names of the 8 most widely used herbal supplements (ginkgo biloba, St John's wort, echinacea, ginseng, garlic, saw palmetto, kava kava, and valerian root). We analyzed the health content of all Web sites listed on the first page of the search results. We analyzed all accessible, English-language Web sites that pertained to oral herbal supplements. A total of 522 Web sites were identified; of these, 443 sites met inclusion criteria for the analysis. The nature of the Web site (retail or nonretail), whether it was a sponsored link, and all references, indications, claims, and disclaimers were recorded. Two reviewers independently categorized medical claims as disease or nondisease according to Food and Drug Administration criteria. Among 443 Web sites, 338 (76%) were retail sites either selling product or directly linked to a vendor. A total of 273 (81%) of the 338 retail Web sites made 1 or more health claims; of these, 149 (55%) claimed to treat, prevent, diagnose, or cure specific diseases. More than half (153/292; 52%) of sites with a health claim omitted the standard federal disclaimer. Nonretail sites were more likely than retail sites to include literature references, although only 52 (12%) of the 443 Web sites provided referenced information without a link to a distributor or vendor. Consumers may be misled by vendors' claims that herbal products can treat, prevent, diagnose, or cure specific diseases, despite regulations prohibiting such statements. Physicians should be

    Regionally distinct wine characteristics (terroir) are an important aspect of wine production and consumer appreciation. Microbial activity is an integral part of wine production, and grape and wine microbiota present regionally defined patterns associated with vineyard and climatic conditions, but the degree to which these microbial patterns associate with the chemical composition of wine is unclear. Through a longitudinal survey of over 200 commercial wine fermentations, we demonstrate that both grape microbiota and wine metabolite profiles distinguish viticultural area designations and individual vineyards within Napa and Sonoma Counties, California. Associations among wine microbiota and fermentation characteristics suggest new links between microbiota, fermentation performance, and wine properties. The bacterial and fungal consortia of wine fermentations, composed from vineyard and winery sources, correlate with the chemical composition of the finished wines and predict metabolite abundances in finished wines using machine learning models. The use of postharvest microbiota as an early predictor of wine chemical composition is unprecedented and potentially poses a new paradigm for quality control of agricultural products. These findings add further evidence that microbial activity is associated with wine terroir Wine production is a multi-billion-dollar global industry for which microbial control and wine chemical composition are crucial aspects of quality. Terroir is an important feature of consumer appreciation and wine culture, but the many factors that contribute to terroir are nebulous. We show that grape and wine microbiota exhibit regional patterns that correlate with wine chemical composition, suggesting that the grape microbiome may influence terroir In addition to enriching our understanding of how growing region and wine properties interact, this may provide further economic incentive for agricultural and enological practices that maintain regional

    Kesarwani, Kritika; Gupta, Rajiv

    2013-01-01

    Recently, the use of herbal medicines has been increased all over the world due to their therapeutic effects and fewer adverse effects as compared to the modern medicines. However, many herbal drugs and herbal extracts despite of their impressive in-vitro findings demonstrates less or negligible in-vivo activity due to their poor lipid solubility or improper molecular size, resulting in poor absorption and hence poor bioavailability. Nowadays with the advancement in the technology, novel drug delivery systems open the door towards the development of enhancing bioavailability of herbal drug delivery systems. For last one decade many novel carriers such as liposomes, microspheres, nanoparticles, transferosomes, ethosomes, lipid based systems etc. have been reported for successful modified delivery of various herbal drugs. Many herbal compounds including quercetin, genistein, naringin, sinomenine, piperine, glycyrrhizin and nitrile glycoside have demonstrated capability to enhance the bioavailability. The objective of this review is to summarize various available novel drug delivery technologies which have been developed for delivery of drugs (herbal), and to achieve better therapeutic response. An attempt has also been made to compile a profile on bioavailability enhancers of herbal origin with the mechanism of action (wherever reported) and studies on improvement in drug bioavailability, exhibited particularly by natural compounds.

    Herbal distillates have been used as beverages, for flavoring, or as phytomedicines in many countries for a long time. Recently, the occurrence of blindness after drinking herbal distillates has created concerns in Iran. The aim of this study was to determine the concentrations of methanol in herbal distillates produced in Iran. Eighty-four most commonly used herbal distillates purchased from herbal distillate factories were analyzed for methanol contents by gas chromatography and flame ionization detection, with ethanol as internal standard. In 15 herbal distillates, the methanol concentration was below the limit of quantitation. The methanol concentrations in all samples ranged from 43 to 277 mg/L. Forty-five samples contained methanol in excess of the Iranian standard. The maximum concentration was found in an herbal distillate of Mentha piperita (factory E) (277±12), and the minimum in a distillate of Carum carvi (factory B) (42.6 ± 0.5). Since the 45 Iranian herbal distillates containing methanol levels were beyond the legal limits according to the Iranian standard, it seems necessary to monitor the amount of methanol and give a warning to watch out for the latent risk problem of methanol uptake, and establish a definitive relationship between the degree of intoxication observed and the accumulation of methanol in the blood.

    Full Text Available Use of herbal medicine in the treatment of liver cancer has a long tradition. The compounds derived from the herb and herbal composites are of considerable interest among oncologists. In the past, certain herbal compounds and herbal composite formulas have been studied through in vitro and in vivo as an anti-hepatocellular carcinoma (HCC agent, enhancing our knowledge about their biologic functions and targets. However there is a significant distinction between the herbal medicine and the herbal production even though both are the plant-based remedies used in the practice. In this article, for the sake of clarity, the effective herbal compounds and herbal composite formulas against HCC are discussed, with emphasizing the basic conceptions of herbal medicine in order to have a better understanding of the prevention and treatment of HCC by herbal active compounds and herbal composite formulas.

    The relative proportion of water and ethanol present in alcoholic beverages can significantly influence the perception of wine sensory attributes. This study therefore investigated changes in wine ethanol concentration due to evaporation from wine glasses. The ethanol content of commercial wines exposed to ambient conditions while in wine glasses was monitored over time. No change in wine ethanol content was observed where glasses were covered with plastic lids, but where glasses were not covered, evaporation had a significant impact on wine ethanol content, with losses from 0.9 to 1.9% alcohol by volume observed for wines that received direct exposure to airflow for 2 h. Evaporation also resulted in decreases in the concentration of some fermentation volatiles (determined by gas chromatography-mass spectrometry) and a perceptible change in wine aroma. The rate of ethanol loss was strongly influenced by exposure to airflow (i.e., from the laboratory air-conditioning unit), together with certain glass shape and wine parameters; glass headspace in particular. This is the first study to demonstrate the significant potential for ethanol evaporation from wine in wine glasses.

    The uses of herbal products are not regulated in Nigeria and in many low-income countries and are freely available to everyone. The safety of these herbal medicines is poorly understood. This study characterizes the content of cadmium, copper, iron, nickel, selenium, zinc, lead and mercury in a random sample of Nigerian traditional products. Ready-to-use herbal products were purchased from the open market and digested using HNO{sub 3}.The heavy metal content of the digested filtrate was determined by atomic absorption spectrometry Uni-cam Model 929. The result showed that 100% of the samples contained elevated amounts of heavy metals. These data alert us to the possibility of heavy metal toxicity from herbal products in Nigeria. The public health hazards from ingestion of herbal medicines should be identified and disclosed by in-depth risk assessment studies.

    Vitamin D deficiency is becoming endemic in many parts of the world. To study vitamin D status in Egyptian females of different age groups. A cross-sectional study was conducted on 404 females, who were categorized into group 1 (51 nursing females); group 2 (50 pregnant females); group 3 (208 females of childbearing age); group 4 (38 elderly females); and group 5 (57 geriatric females). Females completed a questionnaire regarding dietary calcium and vitamin D intake, sun exposure, and clothing habits, and performed laboratory tests including calcium, PO4, alkaline phosphatase, intact PTH, and 25-OH vitamin D levels. Median and IQR of vitamin D levels across groups 1, 2, 3 and 5 were in the deficient range, being lowest in groups 3, 5, and 1, respectively. Vitamin D deficiency was found in 72.6% of the nursing group, 54% of the pregnant group, 72% of the childbearing age group, 39.5% of the elderly group, and 77.2% of the geriatric group. Vitamin D was significantly higher in non-veiled females [23ng/dl] as compared to veiled females [16.7ng/dl]. Vitamin D levels with poor, fair, and good sun exposure were 14.1, 14, and 37ng/dl, respectively. These results show a high prevalence of vitamin D deficiency among healthy Egyptian females.

    Angiotensin-1-converting enzyme (ACE) is a crucial player in vascular homeostasis and in the pathogenesis of atherosclerosis and hypertension. The present study was conducted to determine whether there is an association between the ACE insertion/deletion (I/D) polymorphism and ischemic stroke in Egyptian population. Also, we analyzed the ACE gene I/D polymorphism as a risk factor for small-vessel (SV) versus large-vessel (LV) disease. Sixty patients with ischemic stroke were included: 30 with SV disease and 30 with LV disease. In addition, a control group of 30 apparent healthy subjects were studied. Clinical assessment, computed tomography, magnetic resonance imaging brain, and genetic study using the polymerase chain reaction of ACE gene were done for all subjects. We found that the distribution of ACE gene polymorphism frequency was significantly different between the 3 groups. The DD genotype was far more common in stroke patients compared to controls. It was also significantly more common in each of the patient groups compared to controls but rather similar in the 2 patient groups with SV and LV diseases. We found that the ACE gene deletion/deletion genotype is common in Egyptian patients with non-cardioembolic ischemic stroke but does not appear to be specific neither to SV nor to LV disease.

    Full Text Available This study elaborates and analyzes the phenomenon and concept of political Islam, the reasons of the increased role of the Islamists and their political and reformist tendencies in the light of the Egyptian revolution of Arab Spring, reasons and the main factors that have contributed on their advent into power and their influence in that time, the issue of the application of Islamic Sharia and complex realities about this dilemma. The revolutions of Arab Spring, including the Egyptian revolution, are considered one of the most important and most dangerous events in the XXI century after the terrorist attacks of 11 September 2001, not only in the Middle East but throughout the world because of their impact on peace and global security. The growth of the phenomenon of political Islam and the advent of Islamists into power in Egypt has represented one of the most remarkable features of this sudden revolution. No doubt that the issue of the relationship between Islam and the state's political system raises many confusing questions for many people. In this sense the importance of this study will directly identify the fact that the leadership of Islamists in Egypt is not the implementation of Islamic Sharia but their movements and ideology.

    "The main objective of this paper is to evaluate the impact of the large remittances made by Egyptian migrants to their home country on the Egyptian economy. In order to study this impact, we use the implications of the standard Keynesian model. We estimated the structural equations of the model using annual data for the Egyptian economy over the period from 1970 to 1984.... The results suggest that remittances have had a strong positive impact on GNP in Egypt." The authors note that remittances especially affect private consumption spending. Policy implications concerning labor migration are discussed. (SUMMARY IN FRE AND SPA) excerpt

    A methodology for the determination of volatile compounds in red wine using headspace solid phase microextraction (HS-SPME) combined with gas chromatography-ion trap/ mass spectrometry (GC-IT/MS) and flame ionization detector (GC -FID) was developed, validated and applied to a sample of Brazilian red wine. The optimization strategy was conducted using the Plackett-Burman design for variable selection and central composite rotational design (CCRD). The response surface methodology showed that the performance of the extraction of the volatile compounds using divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) fiber is improved with no sample dilution, the addition of 30% NaCl, applying an extraction temperature of 56°C and extraction time of 55min. The qualitative method allowed the extraction and identification of 60 volatile compounds in the sample studied, notably the classes of esters, alcohols, and fatty acids. Furthermore, the method was successfully validated for the quantification of 55 volatile compounds of importance in wines and applied to twelve samples of Merlot red wine from South of Brazil. The calculation of the odor activity value (OAV) showed the most important components of the samples aroma. Ethyl isovalerate, ethyl hexanoate, 1-hexanol, octanoic acid and ethyl cinnamate had the greatest contribution to the aroma of the wines analyzed, which is predominantly fruity with the presence of herbal and fatty odors.

    The feasibility of exploiting Raman scattering to analyze white wines has been investigated using 3 different wavelengths of the incoming laser radiation in the near-UV (325 nm), visible (532 nm) and near infrared (785 nm). To help in the interpretation of the Raman spectra, the absorption properties in the UV-visible range of two wine samples as well as their laser induced fluorescence have also been investigated. Thanks to the strong intensity enhancement of the Raman scattered light due to electronic resonance with 325 nm laser excitation, hydroxycinnamic acids may be detected and analyzed selectively. Fructose and glucose may also be easily detected below ca. 1000 cm(-1). This feasibility study demonstrates the potential of the Raman spectroscopic technique for the analysis of white wines.

    There are numerous studies indicating that a moderate consumption of red wine provides certain health benefits, such as the protection against neurodegenerative diseases. This protective effect is most likely due to the presence of phenolic compounds in wine. Wine polyphenolic compounds are well known for the antioxidant properties. Oxidative stress is involved in many forms of cellular and molecular deterioration. This damage can lead to cell death and various neurodegenerative disorders, such as Parkinson's or Alzheimer's diseases. Extensive investigations have been undertaken to determine the neuroprotective effects of wine-related polyphenols. In this review we present the neuroprotective abilities of the major classes of wine-related polyphenols.

  20. Associations among Wine Grape Microbiome, Metabolome, and Fermentation Behavior Suggest Microbial Contribution to Regional Wine Characteristics

    ABSTRACT Regionally distinct wine characteristics (terroir) are an important aspect of wine production and consumer appreciation. Microbial activity is an integral part of wine production, and grape and wine microbiota present regionally defined patterns associated with vineyard and climatic conditions, but the degree to which these microbial patterns associate with the chemical composition of wine is unclear. Through a longitudinal survey of over 200 commercial wine fermentations, we demonstrate that both grape microbiota and wine metabolite profiles distinguish viticultural area designations and individual vineyards within Napa and Sonoma Counties, California. Associations among wine microbiota and fermentation characteristics suggest new links between microbiota, fermentation performance, and wine properties. The bacterial and fungal consortia of wine fermentations, composed from vineyard and winery sources, correlate with the chemical composition of the finished wines and predict metabolite abundances in finished wines using machine learning models. The use of postharvest microbiota as an early predictor of wine chemical composition is unprecedented and potentially poses a new paradigm for quality control of agricultural products. These findings add further evidence that microbial activity is associated with wine terroir. PMID:27302757

  8. Traditional use and safety of herbal medicines

    Directory of Open Access Journals (Sweden)

    Davyson de L. Moreira

    Full Text Available In the European Union, traditional herbal medicines that are regarded as "acceptably safe, albeit not having a recognized level of efficacy" fit into a special category of drugs ("traditional herbal medicine products" for which requirements of non-clinical and clinical studies are less rigorous. A regulation proposal published by the Brazilian National Health Surveillance (Anvisa defines a similar drug category ("traditional phytotherapeutic products" for registration purposes. Regarding herbal medicines, both agencies seem to be lenient regarding proof of efficacy, and consider long-standing folk use as evidence of safety and a waiver of a thorough toxicological evaluation. Nonetheless, several herbal products and constituents with a long history of folk usage are suspected carcinogenic and/or hepatotoxic. Herbal products have also been shown to inhibit and/or induce drug-metabolizing enzymes. Since herbal medicines are often used in conjunction with conventional drugs, kinetic and clinical interactions are a cause for concern. A demonstration of the safety of herbal medicines for registration purposes should include at least in vitroand in vivogenotoxicity assays, long-term rodent carcinogenicity tests (for drugs intended to be continuously used for > 3 months or intermittently for > 6 months, reproductive and developmental toxicity studies (for drugs used by women of childbearing age, and investigation of the effects on drug-metabolizing enzymes.

    The concept of wine complexity has gained considerable interest in recent years, both for wine consumers and wine scientists. As a consequence, some research programs concentrate on the factors that could improve the perceived complexity of a wine. Notably, the possible influence of microbiological factors is particularly investigated. However, wine complexity is a multicomponent concept not easily defined. In this review, we first describe the actual knowledge regarding wine complexity, its perception, and wine chemical composition. In particular, we emphasize that, contrary to expectations, the perception of wine complexity is not related to wine chemical complexity. Then, we review the impact of wine microorganisms on wine complexity, with a specific focus on publications including sensory analyses. While microorganisms definitively can impact wine complexity, the underlying mechanisms and molecules are far from being deciphered. Finally, we discuss some prospective research fields that will help improving our understanding of wine complexity, including perceptive interactions, microbial interactions, and other challenging phenomena.

    Studying ancient Egyptian tombs have long been an important source of information regarding many aspects of Egyptian religion. Walls of New Kingdom tombs are often decorated with plenty of painted religious scenes. While they were primarily private structures containing images selected by the person who expected to be housed there for eternity, the funerary monuments also reflect religious beliefs. While numerous researches focused on many of the religious scenes depicted on the walls of anci...

    Full Text Available The objective of this study was to explore the evolution of internal and external commercialization of Brazilian sparkling wines during the period between 1986 and 2015, giving an overview of the current situation and its market trends, and highlighting the importance of Brazil in the world scenario for sparkling wines. This research is based on quantitative data sources provided by different institutions: International Organization of Vine and Wine (OIV, Brazilian Union of Viticulture (UVIBRA, Ministry of Agriculture, Livestock and Supply (MAPA and Brazilian Agricultural Research Corporation (EMBRAPA. Brazil is a promising country for the sparkling wine market. From 1986–2015, there was an increase of 465.6% in the sales of sparkling wine in the Brazilian domestic market, especially the last ten, which accounted for an increase of 215.7%. In 1998, Brazilian sparkling wines accounted for 70.5% of sparkling wines sold in Brazil. Today, they represent 82.1%of national market, and proved to be one of the most prestigious products from Brazilian viticulture when compared, for example, to non-sparkling wines, which 79% are imported wines. Of the imported sparkling wines consumed in Brazil, six countries account for 98.5% of the market (France: 32.7%; Italy: 24.8% and Spain: 21.9%. The volume exportation of Brazilian sparkling wine has grown significantly in recent years (4,210.2%, with Paraguay, China, Uruguay, the United States, France and the United Kingdom being the major buyers. The evolution of exports shows that Brazilian sparkling wine becomes an alternative to those produced in traditional countries, such as France, Italy and Spain, due to their quality and price. There is an increase in the commercialization of sparkling wines in the Brazilian domestic market, in addition to the growing participation of Brazil in the volume of exports in the world market, placing Brazil in a leading position in the production and sale of sparkling wines.

  4. The role and influence of wine awards as perceived by the South African wine consumers

    Directory of Open Access Journals (Sweden)

    F. J. Herbst

    2009-12-01

    Full Text Available Purpose: The purpose of this study was to examine whether, in the mind of the consumer, wine awards do indeed play a significant role in influencing consumer choices. Initially, a literature review was conducted to establish the role of wine awards in wine marketing. Problem investigated: The increasing number of wine competitions appears to dilute the value of wine awards as a marketing tool. The local wine consumers are currently bombarded by a variety of wine choices and need to use cues to assist them in making buying decisions. Consumers are also sceptical about the honesty of producers in marketing their awards. The question arises, whether, in the minds of South Africa's wine consumers, awards play a strong enough role in influencing their choice when buying wine. Research design: A convenience sample was drawn among South African wine consumers by using an online survey questionnaire. A sample of 285 was realised and the data analysed by using descriptive and inferential statistical methods. Findings and implications: Wine awards are indeed recognised by the consumer as a cue that shapes their choices / selection criteria, but their importance is relatively low compared to other cues such as variety, vintage, producer, production method, packaging, place of origin and price. Yet, having established that decision-making is a complex set of interactions, wine awards do nevertheless play a role in supporting a decision in certain circumstances and for certain customer segments. Generally speaking, it was found that the more sophisticated a consumer (connoisseur is the less regard exists for wine awards. Not only do wine awards have lesser power in shaping decisions, but also attitudes towards the concept of wine awards are more negative. Lesser informed consumers tend to take more guidance from, and are less opinionated about the concept of wine awards. An independent monitoring authority is seen as a solution to raise the profile of wine

    In addition to the workers in uranium mines, the staff of other underground mines, such as workers in underground phosphate mines, can be exposed to 222 Rn and its progeny. In this study the individual radon progeny concentrations were measured in three Egyptian underground phosphate mines to estimate the occupational exposure of the workers at those sites. A filter method was used to measure individual radon progeny concentrations ( 218 Po, 214 Pb and 214 Po). The reported mean values of radon progeny concentrations exceed the action levels which are recommended by ICRP 65 (1993). Based on the measured individual radon progeny concentrations ( 218 Po, 214 Pb and 214 Po) in these mines, the annual effective dose for the workers has been calculated using the lung dose model of ICRP 66 (1994). According to the obtained results, some countermeasures were recommended in this study to minimise these exposure levels. (author)

    This paper describes the techniques of three dimensional imaging and stereolithography based on serial CAT-scans applied to the examination of the skull of an Egyptian mummy. Both the three dimensional image and the polymeric cast of the mummy skull presented finer details. It was confirmed that the subject was a male, approximately 30 - 35 years old. Fracturing of the ethmoid bone, e=sequelae to the removal of the brain, was observed in both types of presentations. Apart from this and signs of parodontitis, no pathology was observed. Stereolithography is a most powerful, non-destructive approach to the study of mummies. It might solve some of the problems of reburials, and further be of value in forensic medicine and paleo-ontology. (authors).

    Fabritius discovered the first variable star, Mira, in 1596. Holwarda determined the 11 months period of Mira in 1638. Montanari discovered the next variable star, Algol, in 1669. Its period, 2.867 days, was determined by Goodricke (178). Algol was associated with demon-like creatures, "Gorgon" in ancient Greek and "ghoul" in ancient Arab mythology. This indicates that its variability was discovered much before 1669 (Wilk 1996), but this mythological evidence is ambiguous (Davis 1975). For thousands of years, the Ancient Egyptian Scribes (AES) observed stars for timekeeping in a region, where there are nearly 300 clear nights a year. We discovered a significant periodicity of 2.850 days in their calendar for lucky and unlucky days dated to 1224 BC, "the Cairo Calendar". Several astrophysical and astronomical tests supported our conclusion that this was the period of Algol three millennia ago. The "ghoulish habits" of Algol could explain this 0.017 days period increase (Battersby 2012).

    Although hemorrhoids are one of the most common diseases in the world, the exact etiology underlying the development of hemorrhoids is not clear. Many different ointments are currently used to treat hemorrhoids; however, there is little evidence of the efficacy of these treatments to support their use. The aim of this study was to compare different herbal creams used for the treatment of hemorrhoids. Twenty-eight male Wistar albino rats, 6-8 weeks old and weighing 160-180 g, were used in this study as 1-control, 2-croton oil, 3-croton oil+fig leaves+artichoke leaves+walnut husks and 4-croton oil+fig leaves+artichoke leaves+walnut husks+horse chestnut fruit. After 3 days of croton oil application, rats were treated with 0.1 ml of cream or saline twice a day for 15 days by syringe. Tissue and blood samples were collected for histological, immunohistochemical and biochemical studies. Statistical significance was determined using one-way ANOVA followed by Tukey's multiple comparison tests. Croton oil administration resulted in severe inflammation. The third group showed partial improvement in inflammation; however, the greatest degree of improvement was seen in the fourth group, and some recovered areas were observed. Myeloperoxidase immunoreactivity was found to be decreased in the third and fourth groups compared to the second group. Additionally, biochemical analyses (Myeloperoxidase, Malondyaldehyde, nitrate/nitrite and nitrotyrosine levels and Superoxide Dismutase activity) were in agreement with the histological and immunohistochemical results. In conclusion, croton oil causes inflammation in the anal area and results in hemorrhoids. Treatment with our herbal hemorrhoid creams demonstrated anti-inflammatory and anti-oxidant effects in this model.

    Full Text Available More than 1400 herbal products or herbal-derived compounds are commonly commercialised for health uses worldwide (Tyler, 1996. Herbs are considered dietary supplements, and therefore are subjected to a very limited form of regulation, and advertisements normally highlight their potential activities without mentioning any side effect. Also, herbs are generally believed to be 'natural', and hence safe. Many nutritional supplements contains herb compounds usually not present in the diet (e.g. Ginko biloba, horse- chestnut, and only 10% of the herbs used in nutritional supplements are commonly present in the food (e.g. garlic, soy, blueberry, green the, ginger, curcuma (Eisenberg et al., 1993. There is much interest in "alternative natural approaches" in sport. It is appealing for athletes to use 'natural' substances with similar activity to 'pharmacological' ones in term of improving performance, are not considered doping, and are considered side-effects free (Table 1.

    While drugs remain the cornerstone of medicine, herbal medicine is an important comedication worldwide. Thus, precision medicine ought to face this clinical reality and develop "companion diagnostics" for drugs as well as herbal medicines. Yet, many are in denial with respect to the extent of use of traditional/herbal medicines, overlooking that a considerable number of contemporary therapeutic drugs trace their discovery from herbal medicines. This expert review underscores that absent such appropriate attention on both classical drug therapy and herbal medicines, precision medicine biomarkers will likely not stand the full test of clinical practice while patients continue to use both drugs and herbal medicines and, yet the biomarker research and applications focus only (or mostly) on drug therapy. This asymmetry in biomarker innovation strategy needs urgent attention from a wide range of innovation actors worldwide, including governments, research funders, scientists, community leaders, civil society organizations, herbal, pharmaceutical, and insurance industries, policymakers, and social/political scientists. We discuss the various dimensions of a future convergence map between herbal and conventional medicine, and conclude with a set of concrete strategies on how best to integrate biomarker research in a realm of both herbal and drug treatment. Africa, by virtue of its vast experience and exposure in herbal medicine and a "pregnant" life sciences innovation ecosystem, could play a game-changing role for the "birth" of biomarker-informed personalized herbal medicine in the near future. At this critical juncture when precision medicine initiatives are being rolled out worldwide, precision/personalized herbal medicine is both timely and essential for modern therapeutics, not to mention biomarker innovations that stand the test of real-life practices and implementation in the clinic and society.

    In a context of societal concern about food preservation, the reduction of sulfite input plays a major role in the wine industry. To improve the understanding of the chemistry involved in the SO 2 protection, a series of bottle aged Chardonnay wines made from the same must, but with different concentrations of SO 2 added at pressing were analyzed by ultrahigh resolution mass spectrometry (FT-ICR-MS) and excitation emission matrix fluorescence (EEMF). Metabolic fingerprints from FT-ICR-MS data could discriminate wines according to the added concentration to the must but they also revealed chemistry-related differences according to the type of stopper, providing a wine metabolomics picture of the impact of distinct stopping strategies. Spearman rank correlation was applied to link the statistically modeled EEMF components (parallel factor analysis (PARAFAC)) and the exact mass information from FT-ICR-MS, and thus revealing the extent of sulfur-containing compounds which could show some correlation with fluorescence fingerprints.

    Gustavo Cordero-Bueso

    2018-03-01

    Full Text Available The principal role of wine yeast is to transform efficiently the grape-berries’ sugars to ethanol, carbon dioxide, and other metabolites, without the production of off-flavors. Wine yeast strains are able to ferment musts, while other commercial or laboratory strains fail to do so. The genetic differences that characterize wine yeast strains in contrast to the biological ageing of the veil-forming yeasts in Sherry wines are poorly understood. Saccharomyces cerevisiae strains frequently exhibit rather specific phenotypic features needed for adaptation to a special environment, like fortified wines with ethanol up to 15% (v/v, known as Sherry wines. Factors that affect the correct development of the veil of flor during ageing are also reviewed, along with the related aspects of wine composition, biofilm formation processes, and yeast autolysis. This review highlights the importance of yeast ecology and yeast metabolic reactions in determining Sherry wine quality and the wealth of untapped indigenous microorganisms co-existing with the veil-forming yeast strains. It covers the complexity of the veil forming wine yeasts’ genetic features, and the genetic techniques often used in strain selection and monitoring during fermentation or biological ageing. Finally, the outlook for new insights to protect and to maintain the microbiota of the Sherry wines will be discussed.

    Astringency is one of the most important sensory characteristics of red wine. Although a hierarchically structured vocabulary to describe the mouthfeel sensations of red wine has been proposed, research on consumers' astringency vocabulary is lacking. In this context, the aim of this work was to gain an insight on the vocabulary used by wine consumers to describe the astringency of red wine and to evaluate the influence of wine involvement on consumers' vocabulary. One hundred and twenty-five wine consumers completed and on-line survey with five tasks: an open-ended question about the definition of wine astringency, free listing the sensations perceived when drinking an astringent wine, free listing the words they would use to describe the astringency of a red wine, a CATA question with 44 terms used in the literature to describe astringency, and a wine involvement questionnaire. When thinking about wine astringency consumers freely elicited terms included in the Mouth-feel Wheel, such as dryness and harsh. The majority of the specific sub-qualities of the Mouth-feel Wheel were not included in consumer responses. Also, terms not classified as astringency descriptors were elicited (e.g. acid and bitter). Only 17 out of the 31 terms from the Mouth-feel Wheel were used by more than 10% of participants when answering the CATA question. There were no large differences in the responses of consumer segments with different wine involvement. Results from the present work suggest that most of the terms of the Mouth-feel Wheel might not be adequate to communicate the astringency characteristics of red wine to consumers.

    Plants have been used for medicinal purposes for centuries. Health-oriented individuals are turning to herbal teas as alternatives to caffeinated beverages such as coffee, tea, and cocoa and for low-caloric supplements. The popularity of herbal tea consumption has increased significantly during the past two decades in the U.S. Hundreds of different teas made up of varied mixtures of roots, leaves, seeds, barks, or other parts of shrubs, vines, or trees are sold in health food stores. Although chemists have been characterizing toxic plant constituents for over 100 years, toxicological studies of herbal teas have been limited and, therefore, the safety of many of these products is unknown. Plants synthesize secondary metabolites that are not essential in the production of energy and whose role may be in the defense mechanisms as plant toxins to their interactions with other plants, herbivores, and parasites. Pyrrolizidine alkaloids (PAs) were among the first naturally occurring carcinogens identified in plant products, and their presence in herbal teas is a matter of public health significance. Some herbal tea mixtures and single-ingredient herbal teas have been analyzed for toxic/mutagenic potential by bioassay and chromatographic techniques. Numerous human and animal intoxications have been associated with naturally occurring components, including pyrrolizidine alkaloids, tannins, and safrole. Thus, the prevention of human exposure to carcinogens or mutagens present in herbal tea mixture extracts is crucial. Preparation of infusion drinks prepared from plants appears to concentrate biologically active compounds and is a major source of PA poisoning. The quantity and consumption over a long period of time is of major concern. It is recommended that widespread consumption of herbal infusions should be minimized until data on the levels and varieties of carcinogens, mutagens, and toxicants are made available.

    The European Directive 2004/24/EC introducing a simplified registration procedure for traditional herbal medicinal products, plays an important role in harmonising the current legislation framework for all herbal medicinal products in the European Union (EU). Although substantial achievements have been made under the new scheme, only a limited number of herbal medicinal products from non-European traditions commonly used in Europe have been registered. Therefore, identification of the obstacles, and determination of appropriate means to overcome the major challenges in the registration of non-European traditional herbal medicinal products are of critical importance for the EU herbal medicinal product market. The primary aims of this study were to understand the key issues and obstacles to registration of non-European traditional herbal medicinal products within the EU. The findings may identify the need for more attention on the Community herbal monographs elaborated by the Herbal Medicinal Products Committee (HMPC), as well as further evidence based scientific research on non-European herbal substances/preparations by the scientific community. A systematic evaluation of the herbal substances and preparations included in Community herbal monographs and public statements has been carried out. The focus was herbal substances and preparations derived from non-European traditions. Of the 109 adopted Community herbal monographs, 10 are herbal substances used in Chinese traditional medicine. Where the HMPC issued a public statement because it was unable to elaborate a monograph more than half-involved herbal substances/preparations from non-European traditions. The main reasons herbal substances/preparations from non-European traditions were not accepted for inclusion in the Community herbal monographs have been identified as due to unfulfilled requirements of Directive 2004/24/EC. The most common reasons were the lack of evidence to demonstrate a 15-year minimum

    Full Text Available The use of hedonic price indices is quite common in the wine economics literature, yet they mainly include scores of organoleptic tests and some dummy variables representing varieties and quality signs as geographical indications. This study focuses on the relation between the composition and the price of wines on the example of Hungarian wines. In Hungary, the wine law renders chemical analysis compulsory for all wines released to the market. The study includes five main compounds: actual alcoholic strength, total sugars, total acidity, sugar free extract and pH value and is based on hedonic price indices calculated on a sample of 2,453 wines. Results of several regressions – using different model specifications – consistently show that actual alcoholic strength, sugar content, sugar free extract and pH value are related with the price. Some characteristics have an optimal level, while in other cases the relation is linear.

    Full Text Available The notion of 'wine vessels' in Roman law comprises all the winecontaining recipients. There is no legal standardization of wine vessels by means of volume, and although the terms amphora, urna and culleus are used to designate both the vessels and the units of measure, these are two different meanings of the terms. In regard of the question, whether the vessels make appurtenance of the wine, jurisprudents of proculean school divided them in two categories. In the first category are those that follow legal status of wine, usually amphoras and other jars (cadi which are used for 'packaging', i. e. 'bottling' of the wine. The second category make mostly vats (cuppae and ceramic cisterns (dolia, which don't follow legal status of wine, making instead part of farming equipment of a landed property (instrumentum fundi and it's appurtenance. But, the roman jurists are not consistent regarding criteria for distinguishing these two categories.

    2017-02-14

    Wine, and particularly red wine, is a beverage with a great chemical complexity that is in continuous evolution. Chemically, wine is a hydroalcoholic solution (~78% water) that comprises a wide variety of chemical components, including aldehydes, esters, ketones, lipids, minerals, organic acids, phenolics, soluble proteins, sugars and vitamins. Flavonoids constitute a major group of polyphenolic compounds which are directly associated with the organoleptic and health-promoting properties of red wine. However, due to the insufficient epidemiological and in vivo evidences on this subject, the presence of a high number of variables such as human age, metabolism, the presence of alcohol, the complex wine chemistry, and the wide array of in vivo biological effects of these compounds suggest that only cautious conclusions may be drawn from studies focusing on the direct effect of wine and any specific health issue. Nevertheless, there are several reports on the health protective properties of wine phenolics for several diseases such as cardiovascular diseases, some cancers, obesity, neurodegenerative diseases, diabetes, allergies and osteoporosis. The different interactions that wine flavonoids may have with key biological targets are crucial for some of these health-promoting effects. The interaction between some wine flavonoids and some specific enzymes are one example. The way wine flavonoids may be absorbed and metabolized could interfere with their bioavailability and therefore in their health-promoting effect. Hence, some reports have focused on flavonoids absorption, metabolism, microbiota effect and overall on flavonoids bioavailability. This review summarizes some of these major issues which are directly related to the potential health-promoting effects of wine flavonoids. Reports related to flavonoids and health highlight some relevant scientific information. However, there is still a gap between the knowledge of wine flavonoids bioavailability and their health

    Wine components have been proposed as an alternative natural approach to prevent or treat inflammatory bowel diseases. The difficulty remains to distinguish whether these positive properties are due only to polyphenols in wine or also to the alcohol intake, since many studies have reported ethanol to possess various beneficial effects. Our knowledge of the use of wine components in managing human intestinal inflammatory diseases is still quite limited, and further clinical studies may afford more solid evidence of their beneficial effects.

    The aim of this study was to find out the surface roughness of composite resin veneer after brushing. In this study, 24 specimens of composite resin veneer are divided into three subgroups: brushed without toothpaste, brushed with non-herbal toothpaste, and brushed with herbal toothpaste. Brushing was performed for one set of 5,000 strokes and continued for a second set of 5,000 strokes. Roughness of composite resin veneer was determined using a Surface Roughness Tester. The results were statistically analyzed using Kruskal-Wallis nonparametric test and Post Hoc Mann-Whitney. The results indicate that the highest difference among the Ra values occurred within the subgroup that was brushed with the herbal toothpaste. In conclusion, the herbal toothpaste produced a rougher surface on composite resin veneer compared to non-herbal toothpaste.

    Regular, moderate consumption of red wine is linked to a reduced risk of coronary heart disease and to lower overall mortality, but the relative contribution of wine's alcohol and polyphenol components to these effects is unclear. Here we identify procyanidins as the principal vasoactive polyphenols in red wine and show that they are present at higher concentrations in wines from areas of southwestern France and Sardinia, where traditional production methods ensure that these compounds are efficiently extracted during vinification. These regions also happen to be associated with increased longevity in the population.

Data are from Liv-Ex 100 Fine Wine for fine wine, the Mediobanca Global Wine Industry Share Price for normal wine, and the MSCI World Index as a proxy of the overall stock market. Engle-Granger and Johansen tests were used to detect whether and to what extent the series co-move in the long run and which one of the variables contributes proactively to such an equilibrium by reacting to disequilibria from the long-run path. The estimates highlight that i the two wine indexes have a higher Sharpe ratio compared to the general stock market index, revealing wine stocks as a profitable investment per se, and ii the absence of cointegration among the three series and the existence of possible diversification benefits. In fact, in the long-run price do not move together and, therefore, investors may be better off by including wine stocks into investment portfolios and take advantage of diversification

    Sulfur dioxide (SO2) is important in the winemaking process as it aids in preventing microbial growth and the oxidation of wine. These processes and others consume the SO2 over time, resulting in wines with little SO2 protection. Furthermore, SO2 and sulfiting agents are known to be allergens to many individuals and for that reason their levels need to be monitored and regulated in final wine products. Many of the current techniques for monitoring SO2 in wine require the SO2 to be separated from the wine prior to analysis. This investigation demonstrates a technique capable of measuring free sulfite concentrations in low volume liquid samples in white wine. This approach adapts a known colorimetric reaction to a suspended core optical fiber sensing platform, and exploits the interaction between guided light located within the fiber voids and a mixture of the wine sample and a colorimetric analyte. We have shown that this technique enables measurements to be made without dilution of the wine samples, thus paving the way towards real time in situ wine monitoring. PMID:23112627

    Epilepsy is one of the most common neurological disorders worldwide, with about 80 percent of cases thought to be in developing nations where it is mostly linked to superstition. The limited supply, high cost as well as low efficacy and adverse side effects of antiepileptic drugs (AEDs) is a matter of major concern. Herbal medicine has always been traditionally part of treatment of epilepsy. Herbal medicines are generally well tolerated, with fewer side effects. To highlight some herbal extracts that have been studied for their anticonvulsant activity in animal models, literature search from PubMed and Science Direct, was performed. The keywords for the search consisted of combinations of the following terms: Herbal antiepileptic and/or anticonvulsant, botanicals + epilepsy. Literature published in the last five years was considered. Eighteen (18) anticonvulsant herbal agents are reported and discussed. Experiments mostly consisted of phenotypic screens in rodents, with little diversity in screening methods. In most experiments, the tested extracts prolonged the time to onset of seizures and decreased their duration. Most experimenters implicate potentiation of GABAergic activity as the mode of action of the extracts, even though some experimenters did not fully characterise the bioactive chemical composition of their extracts. Potential herbal remedies have shown positive results in animal models. It remains unclear how many make it into clinical trials and eventually making part of the AED list. More rigorous research, applying strict research methodology with uniform herbal combinations, as well as clinical studies are urgently needed.

These clusters differ in key demographic measures, including sex, age, household income, and education, as well as wine expertise and PROP responsiveness. Wines were collapsed into five categories (dry table, sparkling, fortified, sweet, and wine-based beverages to examine more closely the factors affecting wine liking, total annual intake, and consumption frequency (analysis of variance [ANOVA] followed by Tukey's honest significant difference [HSD] 0.05. Wine expertise was most strongly associated with liking and consumption measures, while PROP responsiveness and alcoholic beverage adventurousness were also important contributors. Neither age nor sex had any large and consistent effects on liking or consumption, although the sex × expertise interaction was significant for some styles.

    Herbal medicines have attracted considerable attention in recent years, which are used to treat Parkinson's disease (PD) in China based on traditional Chinese medicine or modern pharmacological theories. We summarized and analyzed the anti-Parkinsonian activities of herbal medicines and herbal formulations investigated in PD models and provide future references for basic and clinical investigations. All the herbal medicines and herbal formulations were tested on PD models in vitro and in vivo. The relevant compounds and herbal extracts with anti-Parkinsonian activities were included and analyzed according to their genera or pharmacological activities. A total of 38 herbal medicines and 11 herbal formulations were analyzed. The relevant compounds, herbal extracts and formulations were reported to be effective on PD models by modulating multiple key events or signaling pathways implicated in the pathogenesis of PD. The plant species of these herbal medicines belong to 24 genera and 18 families, such as Acanthopanax, Alpinia and Astragalus, etc. These herbal medicines can be an alternative and valuable source for anti-Parkinsonian drug discovery. The plant species in these genera and families may be the most promising candidates for further investigation and deserve further consideration in clinical trials. Active components in some of the herbal extracts and the compatibility law of herbal formulations remain to be further investigated. Copyright © 2012 Elsevier B.V. All rights reserved.

    2014-06-01

    This paper uses Gallup poll data to assess two narratives that have crystallized around the 2011 Egyptian uprising: (1) New electronic communications media constituted an important and independent cause of the protests in so far as they enhanced the capacity of demonstrators to extend protest networks, express outrage, organize events, and warn comrades of real-time threats. (2) Net of other factors, new electronic communications media played a relatively minor role in the uprising because they are low-cost, low-risk means of involvement that attract many sympathetic onlookers who are not prepared to engage in high-risk activism. Examining the independent effects of a host of factors associated with high-risk movement activism, the paper concludes that using some new electronic communications media was associated with being a demonstrator. However, grievances, structural availability, and network connections were more important than was the use of new electronic communications media in distinguishing demonstrators from sympathetic onlookers. Thus, although both narratives have some validity, they must both be qualified. © London School of Economics and Political Science 2014.

  11. Iron forms in some egyptian soils

    EL Kholi, A.F.; Massoud, M.A.; EL-Naggar, H.A.; Gadallah, A.

    1990-01-01

    The present study is an attempt to find out the available forms of iron (Fe 2+ and Fe 3+ ) in five egyptian soils samples, representing alluvial, calcareous and sandy soils. Concerning the iron content of soil either Fe 2+ or Fe 3+ , the tested soil types were relatively arranged in the order alluvial> calcareous> sandy soil. In spite of the considerable variations in the soil content of iron cations, the Fe 2+ /Fe 3+ ratio was almost kept constant around 0.83. The uniformity of the ferrous : ferric ratio in the different tested soil types indicates their similarity in their redox-potential, pH and their environmental conditions, particularly, the aeration and partial O 2 - pressure degree. Fe 2+ /Fe 3+ being less than unity suggests that the Fe 2+ Fe 3+ reaction tends towards the forward direction, i.e., to the Fe 3+ formation. As a result of the pot experiment, significant correlations have been found between the laboratory determined soil Fe 2+ and both of the plant Fe-uptake and the plant dry matter weight

    Chinese herbal medicine is frequently used for treating diabetic peripheral neuropathy in China. Many controlled trials have been undertaken to investigate its efficacy.This is an update of a Cochrane review that was first published in the year 2011. To assess the beneficial effects and harms of Chinese herbal medicine for people with diabetic peripheral neuropathy. On 14 May 2012, we searched the Cochrane Neuromuscular Disease Group Specialized Register CENTRAL (2012, Issue 4 in The Cochrane Library), MEDLINE (January 1966 to May 2012), EMBASE (January 1980 to May 2012), AMED (January 1985 to May 2012) and in October 2012, the Chinese Biomedical Database (CBM) (1979 to October 2012), Chinese National Knowledge Infrastructure Database (CNKI) (1979 to October 2012), and VIP Chinese Science and Technique Journals Database (1989 to October 2012). We searched for unpublished literature in the Chinese Conference Papers Database, and Chinese Dissertation Database (from inception to October 2012). There were no language or publication restrictions. We included randomised controlled trials of Chinese herbal medicine (with a minimum of four weeks treatment duration) for people with diabetic peripheral neuropathy compared with placebo, no intervention, or conventional interventions. Trials of herbal medicine plus a conventional drug versus the drug alone were also included. Two authors independently extracted data and evaluated trial quality. We contacted study authors for additional information. Forty-nine randomised trials involving 3639 participants were included. All trials were conducted and published in China. Thirty-eight different herbal medicines were tested in these trials, including four single herbs (extracts from a single herb), eight traditional Chinese patent medicines, and 26 self concocted Chinese herbal compound prescriptions. The trials reported on global symptom improvement (including improvement in numbness or pain) and changes in nerve conduction

    2011-09-01

    Herbal drugs are gaining worldwide prominence due to their distinct advantages. Developing countries have started exploring the ethnopharmacological approach of drug discovery and have begun to file patents on herbal drugs. The expansion of R&D in Indian herbal research organizations and presence of manufacturing units at non-Indian sites is an indication of the capability to develop new products and processes. The present study attempts to identify innovations in the Indian herbal drug sector by analyzing the patenting trends in India, US and EU. Based on key word and IPC based search at the IPO, USPTO, Esp@cenet and WIPO databases, patent applications and grant in herbal drugs by Indian applicants/assignees was collected for the last ten years (from 1st January 2001 to 31st October 2010). From this collection patents related to human therapeutic use only were selected. Analysis was performed to identify filing trends, major applicants/assignees, disease area and major plant species used for various treatments. There is a gradual increase in patent filing through the years. In India, individual inventors have maximum applications and grants. CSIR, among research organizations and Hindustan Unilever, Avesthagen, Piramal Life Science, Sahajanand Biotech and Indus Biotech among the companies have the maximum granted patents in India, US and EU respectively. Diabetes, cancer and inflammatory disorders are the major areas for patenting in India and abroad. Recent patents are on new herbal formulations for treatment of AIDS, hepatitis, skin disorders and gastrointestinal disorders. A majority of the herbal patents applications and grants in India are with individual inventors. Claim analysis indicates that these patents include novel multi-herb compositions with synergistic action. Indian research organizations are more active than companies in filing for patents. CSIR has maximum numbers of applications not only in India but also in the US and EU. Patents by research

    Herbal usage remains popular as an alternative or complementary form of treatment, especially in Africa. However, the misconception that herbal remedies are safe due to their "natural" origins jeopardizes human safety, as many different interactions can occur with concomitant use with other pharmaceuticals on top of potential inherent toxicity. Cytochrome P450 enzymes are highly polymorphic, and pose a problem for pharmaceutical drug tailoring to meet an individual's specific metabolic activity. The influence of herbal remedies further complicates this. The plants included in this review have been mainly researched for determining their effect on cytochrome P450 enzymes and P-glycoprotein drug transporters. Usage of herbal remedies, such as Hypoxis hemerocallidea, Sutherlandia frutescens and Harpagophytum procumbensis popular in Africa. The literature suggests that there is a potential for drug-herb interactions, which could occur through alterations in metabolism and transportation of drugs. Research has primarily been conducted in vitro, whereas in vivo data are lacking. Research concerning the effect of African herbals on drug metabolism should also be approached, as specific plants are especially popular in conjunction with certain treatments. Although these interactions can be beneficial, the harm they pose is just as great.

    To describe the usefulness of some of the most common tertiary references that healthcare professionals employ to answer requests about herbal and dietary supplements. All requests for information on herbal and dietary supplements received by the drug information service between April and September 2000 were evaluated. Each question was independently reviewed by 4 clinicians using a 4-point scale; 14 references were searched for appropriate answers. The percent of responses for each of the possible scores for each reference overall and by category of question was reported to determine the most helpful references for answering the broadest range of questions. Fifty questions regarding herbal and dietary supplements were analyzed. The electronic databases (Natural Medicine Comprehensive Database, Micromedex) and the Internet site (The Natural Pharmacist) were determined to be overall the most helpful references for providing information on herbal and dietary supplements. The Natural Therapeutics Pocket Guide was the most helpful book reference. These results will facilitate the retrieval of useful information on herbal and dietary supplements and enable healthcare professionals to determine appropriate allocation of resources as they build a drug information library for handling requests about these products.

  16. Thermodynamics of grape and wine tannin interaction with polyproline: implications for red wine astringency.

    McRae, Jacqui M; Falconer, Robert J; Kennedy, James A

    2010-12-08

    The astringency of red wine is largely due to the interaction between wine tannins and salivary proline-rich proteins and is known to change as wine ages. To further understand the mechanisms behind wine astringency change over time, thermodynamics of the interactions between poly(l-proline) (PLP) and grape seed and skin tannins (preveraison (PV) and commercially ripe) or Shiraz wine tannins (2 years old and 9-10 years old) was analyzed using isothermal titration calorimetry (ITC). The nature of these interactions varied with changes to the tannin structure that are associated with maturation. The change in enthalpy associated with hydrophobic interaction and hydrogen bonding decreased with tannin age and the stoichiometry of binding indicated that grape tannins associated with more proline residues than wine tannins, irrespective of molecular size. These results could provide an explanation for the observed change in wine astringency quality with age.

    2002-01-01

    There has been a recent proliferation of medical reference texts intended to guide practitioners whose patients use herbal therapies. We systematically assessed six herbal reference texts to evaluate the information they contain on herbal toxicity. We selected six major herbal references published from 1996 to 2000 to evaluate the adequacy of their toxicological information in light of published adverse events. To identify herbs most relevant to toxicology, we reviewed herbal-related calls to our regional California Poison Control System, San Francisco division (CPCS-SF) in 1998 and identified the 12 herbs (defined as botanical dietary supplements) most frequently involved in these CPCS-SF referrals. We searched Medline (1966 to 2000) to identify published reports of adverse effects potentially related to these same 12 herbs. We scored each herbal reference text on the basis of information inclusiveness for the target 12 herbs, with a maximal overall score of 3. The herbs, identified on the basis of CPCS-SF call frequency were: St John's wort, ma huang, echinacea, guarana, ginkgo, ginseng, valerian, tea tree oil, goldenseal, arnica, yohimbe and kava kava. The overall herbal reference scores ranged from 2.2 to 0.4 (median 1.1). The Natural Medicines Comprehensive Database received the highest overall score and was the most complete and useful reference source. All of the references, however, lacked sufficient information on management of herbal medicine overdose, and several had incorrect overdose management guidelines that could negatively impact patient care. Current herbal reference texts do not contain sufficient information for the assessment and management of adverse health effects of botanical therapies.

    2009-05-01

    Several studies have cited the Mediterranean diet as an example of healthy eating. In fact, the Mediterranean diet has become the reference diet for the prevention of cardiovascular disease. Red wine seems to be an essential component of the diet, since moderate consumption of wine is associated with lower risk and mortality from cardiovascular disease. Evidence is also accumulating that wine helps prevent the development of certain cancers. Of all the many components of wine, resveratrol, which is a natural component specifically present in wine, has been identified as being mainly responsible for these health-promoting properties. Many valuable properties such as cardioprotective and anticarcinogenic activity have been attributed to resveratrol; however, its bioavailability is quite low. The bioactivity of metabolites derived from resveratrol, and the accumulation of resveratrol in vital organs are still under study, but there are high expectations of positive results. Other stilbene compounds are also considered in this review, despite being present in undetectable or very small quantities in wine. The present paper reviews all aspects of the health properties of wine, bioactive compounds found in wine, and their concentrations, bioavailability and possible synergistic effects.

    The effect of vinification techniques on phenolic compounds and antioxidant activity of wine lees are poorly understood. The present study investigated the antioxidant activity of white and red wine lees generated at early fermentation and during aging. In this study, the total phenol content (TPC), total tannin content (TTC), mean degree of polymerization (mDP), and antioxidant activities of five white and eight red wine lees samples from different vinification backgrounds were determined. The results showed that vinification techniques had a significant ( p tannin content of the samples. White wine lees had high mDP content compared with red ones. Catechin (50-62%) and epicatechin contents were the predominant terminal units of polymeric proanthocyanidin extracted from examined samples. Epigallocatechin was the predominant extension unit of white wine lees, whereas epicatechin was the predominant compound in red wine marc. The ORAC (oxygen radical absorbance capacity) assay was strongly correlated with the DPPH (α, α-diphenyl-β-picrylhydrazyl) assay, and the results showed the strong antioxidant activities associated with red wine lees (PN > 35 mg Trolox/g FDM) (PN: Pinot noir lees; FDM: Freeze-dried Material). This study indicates that tannin is one of the major phenolic compounds available in wine lees that can be useful in human and animal health applications.

    Regular consumption of moderate doses of wine is an integral part of the Mediterranean diet, which has long been considered to provide remarkable health benefits. Wine׳s beneficial effect has been attributed principally to its non-alcoholic portion, which has antioxidant properties, and contains a wide variety of phenolics, generally called polyphenols. Wine phenolics may prevent or delay the progression of intestinal diseases characterized by oxidative stress and inflammation, especially because they reach higher concentrations in the gut than in other tissues. They act as both free radical scavengers and modulators of specific inflammation-related genes involved in cellular redox signaling. In addition, the importance of wine polyphenols has recently been stressed for their ability to act as prebiotics and antimicrobial agents. Wine components have been proposed as an alternative natural approach to prevent or treat inflammatory bowel diseases. The difficulty remains to distinguish whether these positive properties are due only to polyphenols in wine or also to the alcohol intake, since many studies have reported ethanol to possess various beneficial effects. Our knowledge of the use of wine components in managing human intestinal inflammatory diseases is still quite limited, and further clinical studies may afford more solid evidence of their beneficial effects.

    Traditional biotechnology has been utilized by human civilization for long in wide aspects of our daily life, such as wine and vinegar production, which can generate new phytochemicals from natural products using micro-organism. Today, with advanced biotechnology, diverse applications and advantages have been exhibited not only in bringing benefits to increase the diversity and composition of herbal phytochemicals, but also helping to elucidate the treatment mechanism and accelerate new drug discovery from Chinese herbal medicine (CHM). Applications on phytochemical biotechnologies and microbial biotechnologies have been promoted to enhance phytochemical diversity. Cell labeling and imaging technology and -omics technology have been utilized to elucidate CHM treatment mechanism. Application of computational methods, such as chemoinformatics and bioinformatics provide new insights on direct target of CHM. Overall, these technologies provide efficient ways to overcome the bottleneck of CHM, such as helping to increase the phytochemical diversity, match their molecular targets and elucidate the treatment mechanism. Potentially, new oriented herbal phytochemicals and their corresponding drug targets can be identified. In perspective, tighter integration of multi-disciplinary biotechnology and computational technology will be the cornerstone to accelerate new arena formation, advancement and revolution in the fields of CHM and world pharmaceutical industry.

    2012-01-01

    Full Text Available There are numerous studies indicating that a moderate consumption of red wine provides certain health benefits, such as the protection against neurodegenerative diseases. This protective effect is most likely due to the presence of phenolic compounds in wine. Wine polyphenolic compounds are well known for the antioxidant properties. Oxidative stress is involved in many forms of cellular and molecular deterioration. This damage can lead to cell death and various neurodegenerative disorders, such as Parkinson’s or Alzheimer’s diseases. Extensive investigations have been undertaken to determine the neuroprotective effects of wine-related polyphenols. In this review we present the neuroprotective abilities of the major classes of wine-related polyphenols.

    Herbal hepatotoxicity is a field that has rapidly grown over the last few years along with increased use of herbal products worldwide. To summarize the various facets of this disease, we undertook a literature search for herbs, herbal drugs and herbal supplements with reported cases of herbal hepatotoxicity. A selective literature search was performed to identify published case reports, spontaneous case reports, case series and review articles regarding herbal hepatotoxicity. A total of 185 publications were identified and the results compiled. They show 60 different herbs, herbal drugs and herbal supplements with reported potential hepatotoxicity, additional information including synonyms of individual herbs, botanical names and cross references are provided. If known, details are presented for specific ingredients and chemicals in herbal products, and for references with authors that can be matched to each herbal product and to its effect on the liver. Based on stringent causality assessment methods and/or positive re-exposure tests, causality was highly probable or probable for Ayurvedic herbs, Chaparral, Chinese herbal mixture, Germander, Greater Celandine, green tea, few Herbalife products, Jin Bu Huan, Kava, Ma Huang, Mistletoe, Senna, Syo Saiko To and Venencapsan(®). In many other publications, however, causality was not properly evaluated by a liver-specific and for hepatotoxicity-validated causality assessment method such as the scale of CIOMS (Council for International Organizations of Medical Sciences).

  16. Can German wine cooperatives compete on quality?

    Directory of Open Access Journals (Sweden)

    Schamel Guenter H.

    2015-01-01

    Full Text Available The paper analyzes how German cooperative wineries compete with private (i.e. non-cooperative wineries regarding reputation, quality categorization and varietal selection. Among the reasons why German cooperatives lag behind in terms of reputation for quality wine are organization principles of cooperatives and the difficulty to manage growers supplying grapes of different qualities. Cooperatives turn their supply of grapes into wine often classified as quality wine without much distinction. Conversely, privately owned wineries growing their own grapes may have more control over quality along their production chain and are able to produce more distinctive wines. In turn, they gain more reputation with final consumers with respect to quality. We analyze data for private and cooperative wineries from Germany. Our objective is to identify key differences in terms of reputation for quality wine production. Specifically, we look at interaction effects based on organizational form (cooperative vs. private and the German wine quality categorization (i.e. basic quality wine vs. Kabinett, Spätlese, or Auslese as well as varietal effects. We employ a hedonic pricing model to test the hypothesis that wines produced by private producers receive a reputation premium relative to cooperatives. Moreover, we hypothesize that private wineries receive a price premium relative to coopera- tives for other than basic quality wines and distinct varieties such as Riesling and Pinot Noir. The empirical analysis confirms both hypotheses. The estimated coefficients indicate that cooperatives are unable to gain quality premium for most quality cat- egories and gain price premiums only for non-distinct varieties such as Lemberger and Dornfelder. We can argue that German cooperatives are stuck in the low quality corner of the quality and variety spectrum and are currently not able to compete with private wineries in terms of quality. This result supports the observation

    2015-12-01

    Full Text Available The main aim of this study is to highlight the wine-growing and wine-making potential of Alba County and the way it can be valorised. Alba county has a rich winegrowing and wine-making heritage, a fact which is due to the long-standing tradition of winegrowing on these area, as well as to the characteristics of the natural factors (relief, geology, climate, soil, favourable for obtaining high-quality wines, the reputation of which has been acquired at national and international competitions. In order to render useful the wine tourism resources, the development of a specific infrastructure is needed, as well as the creation of complex tourist products, able to satisfy a wide range of tourist motivations. An efficient instrument to make productive the wine potential of a region is the „Wine Road" – a tourist trail which includes the tourist attractions of a delimited area, usually with a controlled designation of origin, and also a diverse range of tourist services (transportation, accommodation, catering leisure etc.. In Alba County, the „Wine Road" can be considered as a tourist attraction in itself, but also a means of harnessing the rich cultural-historical and natural heritage and, implicitly, the wine-growing and wine-making heritage.

  18. Metals in wine--impact on wine quality and health outcomes.

    Science.gov (United States)

    Tariba, Blanka

    2011-12-01

    Metals in wine can originate from both natural and anthropogenic sources, and its concentration can be a significant parameter affecting consumption and conservation of wine. Since metallic ions have important role in oxide-reductive reactions resulting in wine browning, turbidity, cloudiness, and astringency, wine quality depends greatly on its metal composition. Moreover, metals in wine may affect human health. Consumption of wine may contribute to the daily dietary intake of essential metals (i.e., copper, iron, and zinc) but can also have potentially toxic effects if metal concentrations are not kept under allowable limits. Therefore, a strict analytical control of metal concentration is required during the whole process of wine production. This article presents a critical review of the existing literature regarding the measured metal concentration in wine, methods applied for their determination, and possible sources, as well as their impact on wine quality and human health. The main focus is set on aluminum, arsenic, cadmium, chromium, copper, iron, manganese, nickel, lead, and zinc, as these elements most often affect wine quality and human health.

  19. Phenolic compounds in Merlot wines from two wine regions of Rio Grande do Sul, Brazil

    Directory of Open Access Journals (Sweden)

    Carlos Eugenio Daudt

    2013-06-01

    Full Text Available In Brazil, the grape and wine production takes place mainly in the state of Rio Grande do Sul, and the region "Serra" is known as the traditional wine region. In the last years, new areas have emerged, with emphasis for the Campanha region; the red wines from this region have low acidity, little color intensity, and are wines to drink while young, even when produced from grape varieties such as Merlot and Cabernet Sauvignon. The objective of this study was to evaluate the influence of different maceration types on the phenolic compounds of Merlot wines made with grapes produced in two regions of Rio Grande do Sul, Serra and Campanha, as well as to identify the key differences between the wines produced. The localization of the vineyards seems to have more influence on the wine characteristics than the maceration type. The color due copigmentation was an important aspect in the wines made with short maceration. The effect of extended maceration was different than the expected for the Campanha region wines; the extended maceration increased the extraction of tannins resulting in greater color intensity and a greater amount of anthocyanins. The pH control seems to be a key factor for the Campanha region wines.

  20. Rosé wine volatile composition and the preferences of Chinese wine professionals.

    2016-07-01

    Rosé wine aromas range from fruity and floral, to more developed, savoury characters. Lighter than red wines, rosé wines tend to match well with Asian cuisines, yet little is known about the factors driving desirability of rosé wines in emerging markets such as China. This study involved Chinese wine professionals participating in blind rosé wine tastings comprising 23 rosé wines from Australia, China and France in three major cities in China. According to the sensory results, a link between the preference, quality and expected retail price of the wines was observed, and assessors preferred wines with prominent red fruit, floral, confectionery and honey characters, and without developed attributes or too much sweetness. Basic wine chemical parameters and 47 volatile compounds, including 5 potent thiols, were determined. Correlations between chemical components, sensory attributes and preference/quality/expected price were visualised by network analysis, revealing relationships that are worthy of further investigation.

    Science.gov (United States)

    Owis, Asmaa Ibrahim; El-Naggar, El-Motaz Bellah

    2016-01-01

    Background: Carob - Ceratonia siliqua L., commonly known as St John's-bread or locust bean, family Fabaceae - is one of the most useful native Mediterranean trees. There is no data about the chromatography methods performed by high performance liquid chromatography (HPLC) for determining polyphenols in Egyptian carob pods. Objective: To establish a sensitive and specific liquid chromatography–electrospray ionization (ESI)-tandem mass spectrometry (MSn) methodology for the identification of the major constituents in Egyptian carob extract. Materials and Methods: HPLC with diode array detector and ESI-mass spectrometry (MS) was developed for the identification and quantification of phenolic acids, flavonoid glycosides, and aglycones in the methanolic extract of Egyptian C. siliqua. The MS and MSn data together with HPLC retention time of phenolic components allowed structural characterization of these compounds. Peak integration of ions in the MS scans had been used in the quantification technique. Results: A total of 36 compounds were tentatively identified. Twenty-six compounds were identified in the negative mode corresponding to 85.4% of plant dry weight, while ten compounds were identified in the positive mode representing 16.1% of plant dry weight, with the prevalence of flavonoids (75.4% of plant dry weight) predominantly represented by two methylapigenin-O-pentoside isomers (20.9 and 13.7% of plant dry weight). Conclusion: The identification of various compounds present in carob pods opens a new door to an increased understanding of the different health benefits brought about by the consumption of carob and its products. SUMMARY This research proposed a good example for the rapid identification of major constituents in complex systems such as herbs using sensitive, accurate and specific method coupling HPLC with DAD and MS, which facilitate the clarification of phytochemical composition of herbal medicine for better understanding of their nature and

    2011-01-01

    Background Over three-quarter of the world's population is using herbal medicines with an increasing trend globally. Herbal medicines may be beneficial but are not completely harmless. This study aimed to assess the extent of use and the general knowledge of the benefits and safety of herbal medicines among urban residents in Lagos, Nigeria. Methods The study involved 388 participants recruited by cluster and random sampling techniques. Participants were interviewed with a structured open- and close-ended questionnaire. The information obtained comprises the demography and types of herbal medicines used by the respondents; indications for their use; the sources, benefits and adverse effects of the herbal medicines they used. Results A total of 12 herbal medicines (crude or refined) were used by the respondents, either alone or in combination with other herbal medicines. Herbal medicines were reportedly used by 259 (66.8%) respondents. 'Agbo jedi-jedi' (35%) was the most frequently used herbal medicine preparation, followed by 'agbo-iba' (27.5%) and Oroki herbal mixture® (9%). Family and friends had a marked influence on 78.4% of the respondents who used herbal medicine preparations. Herbal medicines were considered safe by half of the respondents despite 20.8% of those who experienced mild to moderate adverse effects. Conclusions Herbal medicine is popular among the respondents but they appear to be ignorant of its potential toxicities. It may be necessary to evaluate the safety, efficacy and quality of herbal medicines and their products through randomised clinical trial studies. Public enlightenment programme about safe use of herbal medicines may be necessary as a means of minimizing the potential adverse effects. PMID:22117933

    Full Text Available Tandis que le vin essaie de s’infiltrer dans le répertoire culinaire de la Chine, il s’agit plus qu’un simple processus de flux culinaires globaux du centre vers la périphérie. Le vin chinois est devenu un nouvel outil d’identification ainsi qu’un signe de la position renégociée de cette nation dans le monde. Pour ce qu’elle vaut, l’industrie vinicole sert également l’intérêt de l’État-parti en renforçant sa légitimité et en établissant son agenda politique. Dans cet article, qui rend compte de l’histoire du vin chinois ainsi que sa situation actuelle, la boisson est prise comme exemple des changements culinaires contemporains, mais surtout comme moyen d’explorer les significations et les limites sociales d’une modernité émergente distinctement chinoise. Une modernité qui dans sa volonté apparente d’absorber le nouveau et l’étranger remplace la dichotomie sino-occidentale jusque là prédominante, tout en adhérant toujours aux vieilles rengaines ‘que l’ancien serve le présent’ et ‘que l’étranger serve le chinois.’As grape wine tries to sell its way into the standard culinary repertoire of China, it is more than simply a process of a global culinary flow from the centre to the periphery. Chinese wine has become a new tool for identification as well as a sign of the nation’s renegotiated position in the world. For what it is worth, the wine industry also serves the interest of the party-state by strengthening its legitimacy and substantiating its political agenda. In this article, which reviews China’s wine history as well as the present situation, the drink is taken as an example of contemporary culinary change, but foremost as a means to explore the meanings and social limits of an emergent distinctly Chinese modernity. A modernity that in its apparent willingness to embrace the new and foreign supersedes the hitherto predominant Sino-Western dichotomy, while still adhering to the

    Occupational stress (OS) among teachers predispose to depression and anxiety. No study was done to assess these problems among Egyptian teachers. This study aimed to assess the prevalence of OS, depression and anxiety among Egyptian teachers. A cross sectional study was done on 568 Egyptian teachers. The respondents filled a questionnaire on personal data, and the Arabic version of the Occupational Stress Index (OSI), the Arabic validated versions of Taylor manifest anxiety scale and the Beck Depression Inventory (BDI) were used to assess OS, anxiety and depression respectively. The prevalence of OS, anxiety and depression among teachers was (100%, 67.5% and 23.2%) respectively. OS, anxiety and depression scores were significantly higher among teachers with an age more than 40years, female teachers, primary school teachers, those with inadequate salary, higher teaching experience, higher qualifications and higher workload. A significant weak positive correlation was found between OS scores and anxiety and depression scores. This study indicated the need for future researches to address risk factors of OS and mental disorders among Egyptian teachers, and the need of periodical medical evaluation of teachers and medical and psychological support for the identified cases.

  1. Evaluation of municipal solid waste management in egyptian rural areas.

    2009-01-01

    A two years study was conducted to evaluate the solid waste management system in 143 villages representing the Egyptian rural areas. The study covers the legal responsibilities, service availability, environmental impacts, service providers, financial resources, private sector participation and the quality of collection services. According to UN reports more than 55% of Egyptian population lives in rural areas. A drastic change in the consumption pattern altered the quantity and quality of the generated solid wastes from these areas. Poor solid waste management systems are stigmata in most of the Egyptian rural areas. This causes several environmental and health problems. It has been found that solid waste collection services cover only 27% of the surveyed villages, while, the statistics show that 75% of the surveyed villages are formally covered. The service providers are local villager units, private contractors and civil community associations with a percentage share 71%, 24% and 5% respectively. The operated services among these sectors were 25%, 71% and 100% respectively. The share of private sector in solid waste management in rural areas is still very limited as a result of the poverty of these communities and the lack of recyclable materials in their solid waste. It has been found that direct throwing of solid waste on the banks of drains and canals as well as open dumping and uncontrolled burning of solid waste are the common practice in most of the Egyptian rural areas. The available land for landfill is not enough, pitiable designed, defectively constructed and unreliably operated. Although solid waste generated in rural areas has high organic contents, no composting plant was installed. Shortage in financial resources allocated for valorization of solid waste management in the Egyptian rural areas and lower collection fees are the main points of weakness which resulted in poor solid waste management systems. On the other hand, the farmer's participation

  2. [Pain management with herbal antirheumatic drugs].

    2002-01-01

    Herbal antirheumatics are indicated in painful inflammatory and degenerative rheumatic diseases. Their mechanism of action is broader than that of synthetic antirheumatics. Particular preparations from Devils's Claw with 50 to 100 mg of harpagoside in the daily dosage as well as a particular willow bark extract with 120 to 240 mg salicin in the daily dosage proved efficacy in a number of clinical studies including confirmatory ones. Exploratory studies indicate that these herbal antirheumatics were not inferior to the selective COX-2 inhibitor rofecoxib when treating acute exacerbations of chronic low back pain. For the proprietary nettle root extract IDS23 promising in vitro/in vivo results indicate an anti-inflammatory effect, however there are only 2 open uncontrolled clinical studies available and the proof of efficacy is still missing. Safety data in order to recommend use during pregnancy and lactation are only available for the herbal combination product Phytodolor prepared from aspen, ash and goldenrod. In principle, blackcurrent leaf with not less than 1.5% flavonoids may be an appropriate antirheumatic. Likewise, the seed oils of blackcurrent, evening primrose and borage offering at least 1 to 3 g gammalinolenic acid/day are recommendable. In case superiority versus placebo has been established, proprietary herbal antirheumatics should be administered before the conventional analgesics due to the lower incidence of adverse events.

    Full Text Available Dipika Bansal, Debasish Hota, Amitava ChakrabartiPostgraduate Institute of Medical Education and Research, Chandigarh, IndiaAbstract: Randomized controlled trials provide the best evidence, and is seen as the gold standard for allopathic research. Herbal therapies are not an integral part of conventional care although they are still used by patients in their health care management. These medicines need to be subjected to rigorous research to establish their effectiveness and safety. Clearly defined treatments are required and should be recorded in a manner that enables other suitably trained researchers to reproduce them reliably. Quality control of herbal products is also a prerequisite of credible clinical trials. Methodological strategies for investigating the herbal interventions and the issues regarding appropriate patient selection, randomization and blinding, placebo effects and choice of comparator, occupational standardization and the selection of appropriate study endpoints to prove efficacy are being discussed. This paper will review research options and propose some suggestions for future research design.Keywords: CAM research, herbal therapies, methodology, clinical trial

    In the latest years, a lot of research studies regarding the usage of active agents from plants in the treatment of tumors have been published, but there is no data about successful usage of herbal remedies in the treatment of glioblastoma in humans. The phytotherapy involved five types of herbal medicine which the subjects took in the form of tea, each type once a day at regular intervals. Three patients took herbal medicine along with standard oncological treatment, while two patients applied for phytotherapy after completing medical treatment. The composition of herbal medicine was modified when necessary, which depended on the results of the control scans using the nuclear magnetic resonance technique and/or computed tomography. Forty-eight months after the introduction of phytotherapy, there were no clinical or radiological signs of the disease, in three patients; in one patient, the tumor was reduced and his condition was stable, and one patient lived for 48 months in spite of a large primary tumor and a massive recurrence, which developed after the treatment had been completed. The results achieved in patients in whom tumor regression occurred exclusively through the use of phytotherapy deserve special attention. In order to treat glioblastoma more effectively, it is necessary to develop innovative therapeutic strategies and medicines that should not be limited only to the field of conventional medicine. The results presented in this research paper are encouraging and serve as a good basis for further research on the possibilities of phytotherapy in the treatment of glioblastoma.

    2017-03-06

    Written history allows tracing back Mediterranean and European medical traditions to Greek antiquity. The epidemiological shift triggered by the rise of modern medicine and industrialization is reflected in contemporary reliance and preferences for certain herbal medicines. We sketch the development and transmission of written herbal medicine through Mediterranean and European history and point out the opportunity to connect with modern traditions. An ethnopharmacological database linking past and modern medical traditions could serve as a tool for crosschecking contemporary ethnopharmacological field-data as well as a repository for data mining. Considering that the diachronic picture emerging from such a database has an epidemiological base this could lead to new hypotheses related to evolutionary medicine. The advent of systems pharmacology and network pharmacology opens new perspectives for studying past and current herbal medicine. Since a large part of modern drugs has its roots in ancient traditions one may expect new leads for drug development from novel systemic studies, as well as evidence for the activity of certain herbal preparations.

    2008-04-01

    Full Text Available Wine tourism is experiencing significant development in both new and old European wine regions. In the case of the Canary Islands, wine has been produced and traded for centuries but little is known about the current state or potential for wine tourism on the islands, despite the fact that millions of tourists, including many potential wine tourists, visit the islands each year. In this exploratory study, the perspectives of winery owners and managers on wine tourism are examined via in-depth face-to-face interviews among 23 small winery operators to reveal that the scope for exploiting wine tourism on the islands has been recognized and that some wineries are either already involved in wine tourism, includ-ing as part of a wine trail, or plan to be more involved in the future. It was also discovered, that there were a number of issues that challenge the development of their wine and wine tourism industry, includ-ing competition from non-Canary Island wines and anti-drink-drive laws that are inhibit passers by to consume wine at the cellar door. Operators stressed the need to find a balance between mass tourism and the niche produce of wine. Moreover, the findings identify avenues for future research on wine tourism development in the Canary Islands.

    Full Text Available This work deals with the colour and sensory evaluation of wines and organic wines from conventional cultivation. 6 organic wines and 6 wines from conventional cultivation were evaluated. The methodology describes colour measurements using spectrophotometry and sensory 20-point-scale system of scoring. The colour evaluation of different varieties did not clearly demonstrate impact of growing on lightness or hue and saturation of wine. Conclusive differences in colour (P <0.05 were established, especially for Pinot Blanc and Malverina from white varieties and Medina from red grapes. The greatest colour stability was demonstrated by Moravian Muscat. Sensory evaluation did not show any noticeable differences between the wines of conventional and organic production, there were, however, differences among varieties.

    2010-01-01

    The present review aims to show the state of the art of oxidation mechanisms occurring especially in white wines by taking into account knowledge from different fields in relation to the subject. It is therefore divided into three main parts. First, the mechanisms of oxidation relevant to white wine are discussed in the light of recent scientific literature. Next, the phenomenon of oxygen solubility in wine during the winemaking process, and in particular during bottling is stated theoretically as well as practically. Finally, the aspect of wine conservation after bottling is examined with respect to mass transfers which may occur through the closure, with a special emphasis on cork. Currently, specific physico-chemical properties still make cork closures the most important closure type used for the wine market, and especially for high quality wines. This final section will also include a review of studies performed on this subject, which have been analyzed in detail from a theoretical mass transfer point of view, in order to assess the extent to which the proposed scientific tools and the observed tendencies are relevant to progress in the understanding of the impact of this parameter on the behavior of a wine.

    Due to side effects of synthetic drugs, herbal products are rapidly gaining popularity in the world market. The global herbal market in 2010 was US$65 billion and is estimated to hit US$93 billion in 2015. The Malaysian herbal market is estimated to expand from RM7 billion in 2010 to about RM29 billion by 2020. Inspite of its rich biodiversity and well-practised knowledge of herbal medicine amongst its multi cultured population, the share of Malaysia in the global herbal market is very small and not up to the mark. The present article will deal with the measures to be adopted for global promotion of Malaysian herbal products. The scenario and perceptions of herbal medicine are discussed. (author)

  20. Herbal Hepatotoxicity: Clinical Characteristics and Listing Compilation

    Full Text Available Herb induced liver injury (HILI and drug induced liver injury (DILI share the common characteristic of chemical compounds as their causative agents, which were either produced by the plant or synthetic processes. Both, natural and synthetic chemicals are foreign products to the body and need metabolic degradation to be eliminated. During this process, hepatotoxic metabolites may be generated causing liver injury in susceptible patients. There is uncertainty, whether risk factors such as high lipophilicity or high daily and cumulative doses play a pathogenetic role for HILI, as these are under discussion for DILI. It is also often unclear, whether a HILI case has an idiosyncratic or an intrinsic background. Treatment with herbs of Western medicine or traditional Chinese medicine (TCM rarely causes elevated liver tests (LT. However, HILI can develop to acute liver failure requiring liver transplantation in single cases. HILI is a diagnosis of exclusion, because clinical features of HILI are not specific as they are also found in many other liver diseases unrelated to herbal use. In strikingly increased liver tests signifying severe liver injury, herbal use has to be stopped. To establish HILI as the cause of liver damage, RUCAM (Roussel Uclaf Causality Assessment Method is a useful tool. Diagnostic problems may emerge when alternative causes were not carefully excluded and the correct therapy is withheld. Future strategies should focus on RUCAM based causality assessment in suspected HILI cases and more regulatory efforts to provide all herbal medicines and herbal dietary supplements used as medicine with strict regulatory surveillance, considering them as herbal drugs and ascertaining an appropriate risk benefit balance.

    The use of herbal medicinal products and supplements has increased during last decades. At present, some herbs are used to enhance muscle strength and body mass. Emergent evidence suggests that the health benefits from plants are attributed to their bioactive compounds such as Polyphenols, Terpenoids, and Alkaloids which have several physiological effects on the human body. At times, manufacturers launch numerous products with banned ingredient inside with inappropriate amounts or fake supplement inducing harmful side effect. Unfortunately up to date, there is no guarantee that herbal supplements are safe for anyone to use and it has not helped to clear the confusion surrounding the herbal use in sport field especially. Hence, the purpose of this review is to provide guidance on the efficacy and side effect of most used plants in sport. We have identified plants according to the following categories: Ginseng, alkaloids, and other purported herbal ergogenics such as Tribulus Terrestris , Cordyceps Sinensis. We found that most herbal supplement effects are likely due to activation of the central nervous system via stimulation of catecholamines. Ginseng was used as an endurance performance enhancer, while alkaloids supplementation resulted in improvements in sprint and cycling intense exercises. Despite it is prohibited, small amount of ephedrine was usually used in combination with caffeine to enhance muscle strength in trained individuals. Some other alkaloids such as green tea extracts have been used to improve body mass and composition in athletes. Other herb (i.e. Rhodiola, Astragalus) help relieve muscle and joint pain, but results about their effects on exercise performance are missing.

  2. Activation of wine bentonite with gamma rays

    1997-01-01

    The action of gamma rays on wine bentonite as well as influence of its adsorption and technologic qualities on the composition and stability of wines against protein darkening and precipitation has been studied. The experiments were carried out with wine bentonite produced in the firm Bentonite and irradiated with doses of 0.4, 0.6, 0.8 and 1.0 MR. White and red wines have been treated with irradiated bentonite under laboratory conditions at 1.0 g/dm 3 . All samples are treated at the same conditions. The flocculation rate of the sediment was determined visually. Samples have been taken 24 h later from the cleared wine layers. The following parameters have been determined: clarification, filtration rate, phenolic compounds, calcium, colour intensity, total extracted substances, etc. The volume of the sediment has been determined also. The control samples have been taken from the same unirradiated wines. The results showed better and faster clarification in on the third, the 20th and the 24th hours with using of gamma-irradiated at doses 0.8 and 1.0 MR. The sediment was the most compact and its volume - the smallest compared to the samples treated with bentonite irradiated with doses of 0.6 and 0.4 MR. This ensures a faster clarification and better filtration of treated wines. The bentonite activated with doses of 0.8 and 1.0 MR adsorbs the phenolic compounds and the complex protein-phenolic molecules better. In the same time it adsorbs less extracted substances compared to untreated bentonite and so preserves all organoleptic properties of wine. The irradiated bentonite adsorbs less the monomers of anthocyan compounds which ensures brighter natural colour of wine. The gamma-rays activation consolidates calcium in the crystal lattice of bentonite particles and in this way eliminates the formation of crystal precipitates

    The viticulture industry has been selectively growing vine cultivars with different traits (grape size, shape, color, flavor, yield of fruit, and so forth) for millennia, and small variations in soil composition, water management, climate, and the aspect of vineyards have long been associated with shifts in these traits. As such, many different clonal varieties of vines exist, even within given grape varieties, such as merlot, pinot noir, and chardonnay. The commensal microbial flora that coexists with the plant may be one of the key factors that influence these traits. To date, the role of microbes has been largely ignored, outside of microbial pathogens, mainly because the technologies did not exist to allow us to look in any real depth or breadth at the community structure of the multitudes of bacterial and fungal species associated with each plant. In PNAS, Bokulich et al. (1) used next-generation sequencing of 16S rRNA and internal transcribed spacer ribosomal sequence to determine the relative abundances of bacteria and fungi, respectively, from grape must (freshly pressed grape juice, containing the skins and seeds) from plants in eight vineyards representing four of the major wine growing regions in California. The authors show that the microbiomes (bacterial and fungal taxonomic structure) associated with this early fermentation stage show defined biogeography, illustrating that different wine-growing regions maintain different microbial communities, with some influences from the grape variety and the year of production.

    AIM: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma(HCC). METHODS: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts:(1) personal information regarding the physician(name, age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC development(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC development(P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health(MOH) doctors consider HCV infection as the leading cause of HCC in Egypt(P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening(P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo(P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation.CONCLUSION: In Egypt, physicians

  8. Polyphenols produced during red wine ageing.

    Over the past few years, it has been accepted that a moderate red wine consumption is a factor beneficial to human health. Indeed, people of France and Italy, the two major wine-producing European countries, eat a lot of fatty foods but suffer less from fatal heart strokes than people in North-America or in the northern regions of Europe, where wine is not consumed on a regular basis. For a time, ethanol was thought to be the "good" chemical species hiding behind what is known as the "French paradox". Researchers now have turned their investigations towards a family of natural substances called "polyphenols", which are only found in plants and are abundant in grapes. It is well known that these molecules behave as radical scavengers and antioxidants, and it has been demonstrated that they can protect cholesterol in the LDL species from oxidation, a process thought to be at the origin of many fatal heart attacks. However, taken one by one, it remains difficult to demonstrate which are the best polyphenols as far as their antioxidant activities are concerned. The main obstacle in that kind of research is not the design of the chemical and biological tests themselves, but surprisingly enough, the limited access to chemically pure and structurally elucidated polyphenolic compounds. In this article, particular attention will be paid to polyphenols of red wine made from Vitis vinifera cultivars. With respect to the "French paradox", we address the following question: are wine polyphenolic compounds identical to those found in grapes (skin, pulp and seed), or are there biochemical modifications specifically taking place on the native flavonoids when a wine ages? Indeed, structural changes occur during wine conservation, and one of the most studied of those changes concerns red wine colour evolution, called "wine ageing". As a wine ages, it has been demonstrated that the initially present grape pigments slowly turn into new more stable red pigments. That phenomenon goes on

  9. Wine Flavonoids in Health and Disease Prevention

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Wine, and particularly red wine, is a beverage with a great chemical complexity that is in continuous evolution. Chemically, wine is a hydroalcoholic solution (~78% water that comprises a wide variety of chemical components, including aldehydes, esters, ketones, lipids, minerals, organic acids, phenolics, soluble proteins, sugars and vitamins. Flavonoids constitute a major group of polyphenolic compounds which are directly associated with the organoleptic and health-promoting properties of red wine. However, due to the insufficient epidemiological and in vivo evidences on this subject, the presence of a high number of variables such as human age, metabolism, the presence of alcohol, the complex wine chemistry, and the wide array of in vivo biological effects of these compounds suggest that only cautious conclusions may be drawn from studies focusing on the direct effect of wine and any specific health issue. Nevertheless, there are several reports on the health protective properties of wine phenolics for several diseases such as cardiovascular diseases, some cancers, obesity, neurodegenerative diseases, diabetes, allergies and osteoporosis. The different interactions that wine flavonoids may have with key biological targets are crucial for some of these health-promoting effects. The interaction between some wine flavonoids and some specific enzymes are one example. The way wine flavonoids may be absorbed and metabolized could interfere with their bioavailability and therefore in their health-promoting effect. Hence, some reports have focused on flavonoids absorption, metabolism, microbiota effect and overall on flavonoids bioavailability. This review summarizes some of these major issues which are directly related to the potential health-promoting effects of wine flavonoids. Reports related to flavonoids and health highlight some relevant scientific information. However, there is still a gap between the knowledge of wine flavonoids

    Full Text Available Heart disease is the leading cause of death in the US. Moderate red wine consumption has been linked to a reduction in the risk of death by heart disease and heart attack by 30–50%. With about 600,000 people dying from heart disease in the US each year, red wine has become increasingly popular among health conscious consumers. Wine is often touted for its potential health benefits, but to what extent is “health” a factor when consumers make their consumption decisions for alcoholic beverages? This study aims to further understand how consumers make their beverage choices and to understand the role wine health benefit knowledge plays in the willingness of consumers to purchase wine. The results suggest that consumers value the relationship between food/beverage intake and their health status. Consumers with few health issues were the ones more likely to indicate that they consume wine for health reasons, suggesting a potential market among consumers with known health issues. In addition, consumers who attributed the most health benefits to wine were the ones most likely to drink more wine and pay more for wine if it were health enhanced.

    The use of oak wood pieces in winemaking is increasing, but the acceptance of this technique by consumers is unknown. For that reason, the main aim of this study was to measure consumers' opinion of red wines made with this new technique, their acceptance of them and their intention to purchase these wines. A preference ranking test was also carried out. A specific questionnaire was drawn up for this study and 65 frequent red wine consumers tasted four wines, two aged traditionally in barrels and two macerated with chips, and a forced choice preference test was carried out. Fifty-five per cent of respondents said that they would not buy wines made using oak chips, although most respondents would buy these wines if, after tasting them, they were as pleasant and had the same quality as the wines aged traditionally in barrels. Wines obtained with oak wood fragments were not significantly rejected either by consumers who answered the questionnaire or by consumer tasters, which could be due to the large disparity of preferences found among tasters. The results clearly indicate that producers should develop each wine taking into account the specific preferences of each consumer group. Copyright © 2011 Society of Chemical Industry.

    The use of complementary and alternative medicine including herbal medicine is increasing in many countries including Ghana. However, there is paucity of research on the perspectives of patrons of herbal medicine regarding the facilitators and barriers of herbal medicine use. This study sought to investigate the facilitators and barriers of herbal medicine among Ghanaian adults who use one form of herbal medicine or the other. The study employed an inductive exploratory qualitative approach. It was conducted at a private herbal clinic in Accra. Purposive sampling was employed to recruit 16 participants. Data collection was through individual face-to-face interviews and these were transcribed and analysed using content analysis procedures. It was realized that the factors that enhanced the use of herbal medicine included use of convincing information to enhance the initiation of herbal medicine use, effectiveness of herbal medicine, personal preference for herbal medicine, perceived ineffectiveness of western medicine and integration of spirituality in herbal medicine. The factors that hindered herbal medicine use included negative perceptions and attitudes about herbal medicine, poor vending environment, poor knowledge of vendors, high cost of herbal products at credible herbal clinics and inconsistent effectiveness of some herbal products. Participants desired that the national health insurance scheme will cover the cost of herbal medicine to alleviate the financial burden associated with herbal medicine use. Although some Ghanaians patronize herbal medicine, the negative perceptions about herbal medicine resulting from deceitful producers and vendors call for enhanced education and monitoring to ensure that effective herbal products are used.

    The phenolic composition of red wine impacts upon the color and mouthfeel and thus quality of the wine. Both of these characteristics differ depending on the age of a wine, with the purple of young wines changing to brick red and the puckering or aggressive astringency softening in older wines. This study investigated the color parameters, tannin concentrations and tannin composition of a 50 year series of Cabernet Sauvignon wines from a commercial label as well as 30 year series of Cabernet Sauvignon and Shiraz wines from a separate commercial label to assess the impact of wine age on phenolic composition and concentration. The wine color density in wines of 40 to 50 years old was around 5 AU compared with 16 AU of wine less than 12 months old, which correlated well with the concentration of non-bleachable pigments and pigmented polymers. Conversely, the anthocyanin concentrations in 10 year old wines were substantially lower than that of recently bottled wines (around 100 mg/L compared with 627 mg/L, respectively), adding further evidence that non-bleachable pigments including pigmented polymers play a much larger role in long-term wine color than anthocyanins. No age-related trend was observed for tannin concentration, indicating that the widely noted softer astringency of older red wines cannot necessarily be directly related to lower concentrations of soluble wine tannin and is potentially a consequence of changes in tannin structure. Wine tannins from older wines were generally larger than tannins from younger wines and showed structural changes consistent with oxidation.

    Full Text Available Sparkling wine represents a small but significant proportion of the Australian wine industry’s total production. Yet, Australia remains a significant importer of French Champagne. This study investigated consumer preferences for Australian sparkling wine vs. French Champagne and any compositional and/or sensorial bases for these preferences. A range of French and Australian sparkling wines were analyzed by MIR spectroscopy to determine if sparkling wines could be differentiated according to country of origin. A subset of wines, comprising two French Champagnes, a French sparkling wine and three Australian sparkling wines, were selected for (i descriptive analysis to characterize their sensory profiles and (ii acceptance tests to determine consumer liking (n = 95 Australian wine consumers. Significant differences were observed between liking scores; on average, the $70 French Champagne was liked least and the $12 Australian sparkling wine liked most, but segmentation (based on individual liking scores identified clusters comprising consumers with distinct wine preferences. Interestingly, when consumers were shown wine bottle labels, they considered French wines to be more expensive than Australian wines, demonstrating a clear country of origin influence.

    Conventional cancer therapies, the second leading cause of death worldwide, result in serious side effects and, at best, merely extend the patient's lifespan by a few years. Searching for effective prevention is of high priority in both basic and clinical sciences. In recent decades natural products have been considered to be an important source of cancer chemopreventive agents. Red wine polyphenols, which consisted of various powerful antioxidants such as flavonoids and stilbenes, have been implicated in cancer prevention and that promote human health without recognizable side effects. Since resveratrol, a major component of red wine polyphenols, has been studied and reviewed extensively for its chemopreventive activity to interfere with the multi-stage carcinogenesis, this review focuses on recent progress in studies on cancer chemopreventive activities of red wine polyphenol extracts and fractions as well as other red wine polyphenols, like procyanidin B5 analogues and myricetin.

    Full text: The analytical methods used to determine the isotope ratios of deuterium, carbon-13 and oxygen-18 in wines have gained official recognition from the Office International de la Vigne et du Vin (OIV) and National Organisation of Vine and Wine. The amount of stable isotopes in water and carbon dioxide from plant organic materials and their distribution in sugar and ethanol molecules are influenced by geo-climatic conditions of the region, grape varieties and the year of harvest. For wine characterization, to prove the botanical and geographical origin of the raw material, the isotopic analysis by continuous flow mass spectrometry CF-IRMS has made a significant contribution. This paper emphasize the results of a study concerning the assessing of water adulterated wines and non-grape alcohol and sugar additions at different concentration levels, using CF-IRMS analytical technique.

    Full Text Available The quality of wines is usually evaluated by a sensory panel formed of trained experts or traditional chemical analysis. Over the last few decades, electronic noses and electronic tongues have been developed to determine the quality of foods and beverages. They consist of arrays of sensors with cross-sensitivity, combined with pattern recognition software, which provide a fingerprint of the samples that can be used to discriminate or classify the samples. This holistic approach is inspired by the method used in mammals to recognize food through their senses. They have been widely applied to the analysis of wines, including quality control, aging control or the detection of fraudulence, among others. In this paper, the current status of research and development in the field of electronic noses and tongues applied to the analysis of wines is reviewed. Their potential applications in the wine industry are described. The review ends with a final comment about expected future developments.

    Although a key-concept in Art historical discourse and reasoning, creativity has almost always been avoided as an issue in the discussion of Ancient Egyptian Art, as if the notion was simply irrelevant in such a context. This surprising phenomenon has clearly deep roots in the history of the western vision of Ancient Egyptian Art (and civilization). Nonetheless, the investigation of some (actually quite rare) cases of true copies in Ancient Egyptian Art reveals that creativity operated within...

    Atrial fibrillation (AF) is a common cardiac arrhythmia that is associated with increased risk for cardiovascular disease and overall mortality. Excessive alcohol intake is a well-known risk factor for AF, but this correlation is less clear with light and moderate drinking. Besides, low doses of red wine may acutely prolong repolarization and slow cardiac conduction. Resveratrol, a bioactive polyphenol found in grapes and red wine, has been linked to antiarrhythmic properties and may act as a...

    Each grape variety has its own phenolic profile. However, the concentration of the phenolic compounds present in wine mainly dependson winemaking processes. Phenolic compounds influence wine sensorial characteristics namely taste or mouthfeel, bitterness, astringency and color. Humans can perceive six basic tastes: sweet, salty; sour; umami; fat-taste and bitter taste. This last basic taste is considered as a defense mechanism against the ingestion of potential poisons. Some of the genes,enco...

Due to the growing globalized wine market and the increasing environmental impacts, producers have begun to pay more attention to organic and biodynamic products. Using a systematic literature review, this review aims to investigate the biodynamic production system in the viticulture and winemaking process. In particular, the review examines, 1 the biodynamic practice and its main characteristics including the certification system; 2 the biodynamic market characteristics and the recent trends, the production costs and the marketing strategies adopted by wineries; 3 the demand attributes and wine consumers’ perception on sustainable practices and “green products” such as biodynamic products; and 4 the association between the biodynamic wine chain and the environment. The review highlights the research progress in this field and reflects on the potentiality and needs of the biodynamic viticulture and wine sector. The literature clearly indicates the lack of knowledge regarding, mainly, the biodynamic farming concept and the label. Moreover, while it is clear that consumers are willing to spend more for an organic wine than for a conventional one, there are no data about the willingness to pay for biodynamic wines. Finally, the review concludes with implications and suggestions for further research. Keywords: biodynamic, viticulture, wine, environment, market analysis, consumer

    2017-01-01

    Full Text Available The literature on tourism and events is endless; a niche in this wide research field is represented by food and wine research. The growing interest shown by wine tourists has nurtured the proliferation of wine events and the growth of the wine tourism business; as a consequence, academicians’ interest in this issue has increased. At the same time, research on tourism and events is an evolving field and it has moved from a main economic focus to a broader perspective: some scholars have highlighted how the growing interest towards green and sustainable practices has stimulated academic research and a lot has been done on the management of environmental issues. Given the resonance of wine tourism and the role it has for local and rural development, the interest towards the issue of sustainability in wine is more than warranted. Thus, this paper aims to provide some useful insights about where research has gone and where it is going; a thorough literature review has been performed.

    LH, a 76-year-old Caucasian male, ingested 3 teaspoons (15 mL) of a homemade wine over a 1-h period and became ill. Approximately 1.5 h later, he was taken to the emergency room of a local hospital with symptoms of respiratory distress and weakness. The plant used in making the wine was Angel's trumpet (Datura suaveolens), which reportedly contains varying amounts of scopolamine and atropine. A sample of the wine was collected and analyzed for these two compounds by reversed-phase HPLC chromatography using 97% methanol-3% deionized water. The filtered wine contained an estimated 29 mg scopolamine/mL, which produced a total ingested dose of 435 mg. No atropine was detected. The scopolamine was confirmed by TLC. An oral dose of 50 mg of atropine sulfate in humans has been reported fatal, but there is no reported fatal dose for scopolamine. The alcohol content and 3.8 pH of the homemade wine may have increased the extraction of this compound from the plant material, and the wine fermentation process may have concentrated the original extract.

    The most important dogma in white-wine production is the preservation of the wine aroma and the limitation of the oxidative action of oxygen. In contrast, the aging of Sherry and Sherry-like wines is an aerobic process that depends on the oxidative activity of flor strains of Saccharomyces cerevisiae. Under depletion of nitrogen and fermentable carbon sources, these yeast produce aggregates of floating cells and form an air–liquid biofilm on the wine surface, which is also known as velum or flor. This behavior is due to genetic and metabolic peculiarities that differentiate flor yeast from other wine yeast. This review will focus first on the most updated data obtained through the analysis of flor yeast with -omic tools. Comparative genomics, proteomics, and metabolomics of flor and wine yeast strains are shedding new light on several features of these special yeast, and in particular, they have revealed the extent of proteome remodeling imposed by the biofilm life-style. Finally, new insights in terms of promotion and inhibition of biofilm formation through small molecules, amino acids, and di/tri-peptides, and novel possibilities for the exploitation of biofilm immobilization within a fungal hyphae framework, will be discussed.

    Full Text Available Herbal remedies are widely used for the treatment and prevention of various diseases and often contain highly active pharmacological compounds. Many medicinal herbs and pharmaceutical drugs are therapeutic at one dose and toxic at another. Toxicity related to traditional medicines is becoming more widely recognized as these remedies become popular in the Mediterranean region as well as worldwide. Most reports concerning the toxic effects of herbal medicines are associated with hepatotoxicity although reports of other toxic effects including kidney, nervous system, blood, cardiovascular and dermatologic effects, mutagenicity and carcinogenicity have also been published in the medical literature. This article presents a systematic review on safety of traditional Arab medicine and the contribution of Arab scholars to toxicology. Use of modern cell biological, biochemical, in vitro and in vivo techniques for the evaluation of medicinal plants safety is also discussed.

    Based on the field investigation, this paper researched the germplasms and geoherbs habitat of Chonglou in ancient herbal books systematically. The results showed that, Chonglou in ancient herbal books sometimes referred to certain specific germplasm, while sometimes it referred to many species derived from genus Paris except Sect. Paris. The medicinal material Chonglou in Chinese Materia Medica Bencaotujing and Bencaomengquan was verified as P. polyphylla var. chinensis, which could be P. polyphylla in Xinxiubencao, and it should include P. polyphylla or P. polyphylla var. stenophylla in Bencaogangmu. However, it proved to be a variety of species from Paris that can used as Chonglou in Diannanbencao and Zhiwumingshitukao. Moreover, the origins of Chonglou were correspondingly more diverse, with its producing areas changed from North to South. Therefore, with the resources increasing endangered, the botanical origin of Chonglou should be further studied. Copyright© by the Chinese Pharmaceutical Association.

    Diabetic neuropathy is a chronic complication of diabetes mellitus affecting about 50% of patients. Its symptoms include decreased motility and severe pain in peripheral parts. The pathogenesis involved is an abnormality in blood vessels that supply the peripheral nerves, metabolic disorders such as myo-inositol depletion, and increased nonenzymatic glycation. Moreover, oxidative stress in neurons results in activation of multiple biochemical pathways, which results in the generation of free radicals. Apart from available marketed formulations, extensive research is being carried out on herbal-based natural products to control hyperglycemia and its associated complications. This review is focused to provide a summary on diabetic neuropathy covering its etiology, types, and existing work on herbal-based therapies, which include pure compounds isolated from plant materials, plant extracts, and Ayurvedic preparations.

    Increasingly, winemakers are looking for ways to introduce aroma and flavour diversity to their wines as a means of improving style and increasing product differentiation. While currently available commercial yeast strains produce consistently sound fermentations, there are indications that sensory complexity and improved palate structure are obtained when other species of yeast are active during fermentation. In this study, we explore a strategy to increase the impact of non-Saccharomyces cerevisiae inputs without the risks associated with spontaneous fermentations, through generating interspecific hybrids between a S. cerevisiae wine strain and a second species. For our experiments, we used rare mating to produce hybrids between S. cerevisiae and other closely related yeast of the Saccharomyces sensu stricto complex. These hybrid yeast strains display desirable properties of both parents and produce wines with concentrations of aromatic fermentation products that are different to what is found in wine made using the commercial wine yeast parent. Our results demonstrate, for the first time, that the introduction of genetic material from a non-S. cerevisiae parent into a wine yeast background can impact favourably on the wine flavour and aroma profile of a commercial S. cerevisiae wine yeast.

  4. From Sugar of Grape to Alcohol of Wine: Sensorial Impact of Alcohol in Wine

    Directory of Open Access Journals (Sweden)

    António M. Jordão

    2015-11-01

    Full Text Available The quality of grapes, as well as wine quality, flavor, stability, and sensorial characteristics depends on the content and composition of several different groups of compounds from grapes. One of these groups of compounds are sugars and consequently the alcohol content quantified in wines after alcoholic fermentation. During grape berry ripening, sucrose transported from the leaves is accumulated in the berry vacuoles as glucose and fructose. The wine alcohol content continues to be a challenge in oenology, as it is also the study of the role of chemosensory factors in alcohol intake and consumer preferences. Several technical and scientific advances have occurred in recent years, such as identification of receptors and other important molecules involved in the transduction mechanisms of flavor. In addition, consumers know that wines with high alcohol content can causes a gustatory disequilibrium affecting wine sensory perceptions leading to unbalanced wines. Hence, the object of this review is to enhance the knowledge on wine grape sugar composition, the alcohol perception on a sensorial level, as well as several technological practices that can be applied to reduce the wine alcohol content.

    Tableware size may influence how much food and non-alcoholic drink is consumed. Preliminary evidence of the impact of glass size on purchasing of alcoholic drinks shows an increase in wine sales of almost 10% when the same portion of wine is served in a larger glass. The primary aim of the current study is to test if micro-drinking behaviours act as a mechanism that could underlie this effect, through an increase in drinking rate, sip duration and/or number of sips from a larger glass. In a between-subjects experimental design, 166 young women were randomised to drink a 175 ml portion of wine from either a smaller (250 ml) or larger (370 ml) wine glass. Primary outcomes were three micro-drinking behaviours, assessed observationally using video recordings: drinking rate, sip number and sip duration. Other possible mechanisms examined were satisfaction with the perceived amount of wine served and pleasure of the drinking experience, assessed using self-report measures. Wine drunk from the larger, compared with the smaller glass, was consumed more slowly and with shorter sip duration, counter to the hypothesised direction of effect. No differences were observed in any of the other outcome measures. These findings provide no support for the hypothesised mechanisms by which serving wine in larger wine glasses increases consumption. While micro-drinking behaviours may still prove to be a mechanism explaining consumption from different glass sizes, cross-validation of these results in a more naturalistic setting is needed.

    Full Text Available Rheumatoid arthritis (RA is a debilitating autoimmune disease of global prevalence. The disease is characterized by synovial inflammation leading to cartilage and bone damage. Most of the conventional drugs used for the treatment of RA have severe adverse reactions and are quite expensive. Over the years, increasing proportion of patients with RA and other immune disorders are resorting to complementary and alternative medicine (CAM for their health needs. Natural plant products comprise one of the most popular CAM for inflammatory and immune disorders. These herbal CAM belong to diverse traditional systems of medicine, including traditional Chinese medicine, Kampo, and Ayurvedic medicine. In this paper, we have outlined the major immunological pathways involved in the induction and regulation of autoimmune arthritis and described various herbal CAM that can effectively modulate these immune pathways. Most of the information about the mechanisms of action of herbal products in the experimental models of RA is relevant to arthritis patients as well. The study of immunological pathways coupled with the emerging application of genomics and proteomics in CAM research is likely to provide novel insights into the mechanisms of action of different CAM modalities.

  7. Ancient Egyptian chronology and the astronomical orientation of pyramids

    2000-11-01

    The ancient Egyptian pyramids at Giza have never been accurately dated, although we know that they were built approximately around the middle of the third millennium BC. The chronologies of this period have been reconstructed from surviving lists of kings and the lengths of their reigns, but the lists are rare, seldom complete and contain known inconsistencies and errors. As a result, the existing chronologies for that period (the Old Kingdom) can be considered accurate only to about +/-100 years, a figure that radiocarbon dating cannot at present improve. Here I use trends in the orientation of Old Kingdom pyramids to demonstrate that the Egyptians aligned them to north by using the simultaneous transit of two circumpolar stars. Modelling the precession of these stars yields a date for the start of construction of the Great Pyramid that is accurate to +/-5 yr, thereby providing an anchor for the Old Kingdom chronologies.

    2013-08-01

    Full Text Available This paper deals with questions of the politics of location in knowledge and norm production within the context of Egyptian feminist activism for abandoning female genital cutting practices. It seeks to determine underlying schemes of international campaigning discourse and analyzes how these predicate and complicate Egyptian postcolonial activism. It draws on a broad literature study in addition to fieldwork in Cairo consisting of in-depth interviews with activists and policy makers. My focus is on the national Task Force against FGM from 1994 until 1999 and its subsequent cooptation by the National Council of Childhood and Motherhood. I argue through the concept of catachresis that location matters in setting the terms of anti-FGC discourse and its relation to religion.

    2010-12-01

    Several characteristics of Egyptian culture and civilization could be identified in prehistoric and ancient historic Geto-Dacian territories, belonging to modern Romania (Fig. 1). From early times, magic, religion and philosophy have been part of pre-scientific medicine. Therefore these aspects are to be tackled when speaking of medicine in mythological or legendary ages. Progress of ancient Geto-Dacian medicine was principally ascribed to the interface of local civilizations with ancient Egypt, Greece and Rome. Such connections were well documented and understood in historic times and were mainly based on texts of renowned Greek and Roman historians. Egyptian impact upon Dacia, -the ancient name of today's Romania-, was often explained in terms of indirect Greek- or Roman-mediated influences.The Greek and then the Roman colonies on the Black sea shore, together with later Roman colonies in Dacia Felix, founded in the heart of Transylvania, enabled access for Romania to Mediterranean cultures, including that of Egypt.

    Full Text Available Despite Hong Kong׳s growing wine consumption and the abundance of retail brands available there, the demanding choice task faced by its wine consumers, who are more subject to a mix of Chinese and Western cultural influences than consumers in other South Asian countries, has not been studied until now. This exploratory study aims to delve into the importance of wine label attributes for Hong Kong Chinese wine consumers, and to shed light on the ways in which their perceptions affect their choice of wine. Employing an online survey, the results suggest that Hong Kong Chinese wine consumers look for the top three most searched attributes: wine origin, grape variety, and food and wine pairing. A simple means differences test indicated that a traditional label design is favored over modern and contemporary wine labels, and that yellow is the most preferred color. However, a data-driven segmentation analysis reveals that about 95% of young Hong Kong Chinese wine consumers prefer “elegant contemporary” labels with red as the dominant color. These findings could be useful for wineries entering this market and for wine label designers who wish to better understand how Hong Kong wine consumers assess alternatives when choosing a bottle of wine.

    2002-12-21

    Epidemiological studies have shown a favourable effect of moderate alcohol consumption with regard to atherosclerotic disorders. In addition to alcohol, wine contains a large number of other components including polyphenols. These polyphenols mainly originate from the skins and seeds of grapes and, because of differences in vinification, their variety and concentration is higher in red wine than in white wine. In vitro and ex vivo studies have shown that some of these polyphenols are able to slow down LDL-cholesterol oxidation, stimulate NO production, influence prostaglandin synthesis and inhibit platelet aggregation. However, little is known about their resorption, bioavailability and effectiveness in vivo. Since data from intervention studies with wine polyphenols are also lacking, no statement can yet be made about any clinically relevant effect of these components, in either red or white wine, in terms of cardiovascular diseases.

    Full Text Available The aim of this study is to evaluate the impact of Botrytis cinerea, a noble rot, on the aroma components of Amarone, a dry red wine produced from withered grapes. A comparative analysis of wines obtained from manually selected healthy and botrytized grapes was done. Aroma analysis revealed that most compounds varied significantly according to the percentage of botrytized berries utilized. Botrytized wines contained less fatty acids and more fruity acetates than healthy wines. A positive correlation between the content of N-(3-methylbutylacetamide, sherry lactone and an unidentified compound and the level of fungal infection was also observed. The results indicate that noble rot can significantly modify important aroma components of Amarone wine.

    Full Text Available Literatures concerning the history of West African peoples published from 1900 to 1970 debate�the possible migrations of the Egyptians into West Africa. Writers like Samuel Johnson and�Lucas Olumide believe that the ancient Egyptians penetrated through ancient Nigeria but Leo�Frobenius and Geoffrey Parrinder frowned at this opinion. Using the works of these early�20th century writers of West African history together with a Yoruba legend which teaches�about the origin of their earliest ancestor(s, this researcher investigates the theories that the�ancient Egyptians had contact with the ancient Nigerians and particularly with the Yorubas.Intradisciplinary and/or interdisciplinary implications: There is an existing ideology�amongst the Yorubas and other writers of Yoruba history that the original ancestors of�the Yorubas originated in ancient Egypt hence there was migration between Egypt and�Yorubaland. This researcher contends that even if there was migration between Egypt and�Nigeria, such migration did not take place during the predynastic and dynastic period as�speculated by some scholars. The subject is open for further research.

    We report two Egyptian male genomes (EGP1 and EGP2) sequenced at ~ 30× sequencing depths. EGP1 had 4.7 million variants, where 198,877 were novel variants while EGP2 had 209,109 novel variants out of 4.8 million variants. The mitochondrial haplogroup of the two individuals were identified to be H7b1 and L2a1c, respectively. We also identified the Y haplogroup of EGP1 (R1b) and EGP2 (J1a2a1a2 > P58 > FGC11). EGP1 had a mutation in the NADH gene of the mitochondrial genome ND4 (m.11778 G > A) that causes Leber's hereditary optic neuropathy. Some SNPs shared by the two genomes were associated with an increased level of cholesterol and triglycerides, probably related with Egyptians obesity. Comparison of these genomes with African and Western-Asian genomes can provide insights on Egyptian ancestry and genetic history. This resource can be used to further understand genomic diversity and functional classification of variants as well as human migration and evolution across Africa and Western-Asia. Copyright © 2017.

    Axial thin-collimation state-of-the-art spiral computed tomography (CT) was combined with sagittal and coronal reformatting, three-dimensional (3D) reconstruction, and virtual "fly-through" techniques to nondestructively study nine Egyptian mummies. These techniques provided important paleopathologic and historical information about mummification techniques, depicted anatomy in the most informative imaging plane, illustrated the soft-tissue preservation and physical appearance of mummies in superb detail, and generated an intriguing virtual tour through hollow mummified remains without harming the specimens themselves. Images generated with these methods can help archaeologists and Egyptologists understand these fascinating members of mankind and can serve as adjunct visual aids for laypersons who are interested in mummies. CT has emerged as the imaging modality of choice for the examination of Egyptian mummies due to its noninvasive cross-sectional nature and inherently superior contrast and spatial resolution. As multi-detector row CT and postprocessing tools evolve, the capabilities and applications of CT will continue to proliferate, attesting to the expanded versatility and utility of CT as a noninvasive research tool in the multidisciplinary study of Egyptian mummies.

    Xeroderma pigmentosum (XP) is a rare autosomal recessive hereditary disease characterized by hyperphotosensitivity, DNA repair defects and a predisposition to skin cancers. The most frequently occurring type worldwide is the XP group A (XPA). There is a close relationship between the clinical features that ranged from severe to mild form and the mutational site in XPA gene. The aim of this study is to carry out the mutational analysis in Egyptian patients with XP-A. This study was carried out on four unrelated Egyptian XP-A families. Clinical features were examined and direct sequencing of the coding region of XPA gene was performed in patients and their parents. Direct sequencing of the whole coding region of the XPA gene revealed the identification of two homozygous nonsense mutations: (c.553C >T; p.(Gln185)) and (c.331G>T; p.(Glu111)), which create premature, stop codon and a homodeletion (c.374delC: p.Thr125Ilefs 15) that leads to frameshift and premature translation termination. We report the identification of one novel XPA gene mutation and two known mutations in four unrelated Egyptian families with Xermoderma pigmentosum. All explored patients presented severe neurological abnormalities and have mutations located in the DNA binding domain. This report gives insight on the mutation spectrum of XP-A in Egypt. This would provide a valuable tool for early diagnosis of this severe disease. © 2013 Elsevier B.V. All rights reserved.

    Full Text Available While views may differ on the factors that made the 2011 Egyptian revolution possible, the role of mass media will remain undisputable. The Internet-based social networks caught the Mubarak regime by surprise, and the popular disillusionment with the ‘national’ media led the public to turn to private newspapers and satellite channels for keeping pace with the events. This paper examines the role of specific media during the 18 days of the 2011 Egyptian revolution – from 25 January to 11 February, 2011 – which we have divided into four parts. It discusses how these media contributed to the unfolding of events, conceptualized the protests and the demands of the public, and presented the actors that participated in or opposed the revolution. These points are addressed by discussing the content of the Facebook pages of the Sixth of April Movement and We Are All Khalid Said, as well as that of a private Egyptian newspaper, al-Shuruq, and the state-run newspaper al-Ahram.

    Sensory analysis of wine involves the measurement, interpretation and understanding of human responses to the properties perceived by the senses such as sight, smell and taste. The sensory evaluation of wine is often carried out by wine judges, winemakers and technical staff, and allows characterization of the quality of the wine. However, this method is lengthy, expensive, and its results depend on panel training and the specific vocabulary used by the panel. A robust, rapid, unbiased and inexpensive method to assist in quality assessment purposes will therefore be beneficial for the modern wine industry. This study aims to investigate the relationship between sensory analysis, visible (VIS) and near-infrared (NIR) spectroscopy to assess sensory properties of commercial Australian wine varieties. For the purposes of this study 118 red wine samples (Cabernet Sauvignon, Shiraz, Pinot Noir, Tempranillo, Nebbiolo and blends) graded by a panel of experienced tasters and scored according to the Australian wine show system were scanned in transmission in the VIS and NIR range (400-2,500 nm). Partial least squares regression models were developed between the overall score given by the judges and the combined VIS-NIR spectra, using full cross validation (leave-one-out method). The results showed that NIR spectroscopy was able to predict wine quality scores in red wine samples (R = 0.61 and standard error of prediction of 0.81). The practical implication of this study is that instrumental methods such as VIS-NIR spectroscopy can be used to complement sensory analysis and can facilitate the task at early stages of product development, making high-throughput screening of novel products feasible or maintaining the consistency of the product.

A tourism product club is a product development partnership established and led by the tourism industry stakeholders including small- and/or medium-sized companies. The group pools its resources to develop new marketready products or to increase the value of existing ones. Lodging companies, tour operators, administrators of tourism facilities, tourist associations, government, other companies of the sector and, even, nontourist companies can participate as members of a tourism product club. Following this model, wine tourism can contribute to create a wine tourism product club. In Spain the international promotion of tourist products is carried out through the Turespaña website. The wine tourism product club, The Wine Routes of Spain, is one of the wine tourism product clubs developed by the Spanish government. It is an ambitious project that began in 2001. Nevertheless, other Spanish regions have created more wine tourism product clubs in order to develop their own wine tourism industry such as “Divinum vitae – Where the pleasues are born” created in Castilla–La Mancha in 2006.Keywords: wine, tourism, product club, Spain

  10. Interactions between yeast lees and wine polyphenols during simulation of wine aging: I. Analysis of remnant polyphenolic compounds in the resulting wines.

    Wine aging on yeast lees is a traditional enological practice used during the manufacture of wines. This technique has increased in popularity in recent years for the aging of red wines. Although wine polyphenols interact with yeast lees to a limited extent, such interactions have a large effect on the reactivity toward oxygen of wine polyphenolic compounds and yeast lees. Various domains of the yeast cell wall are protected by wine polyphenols from the action of extracellular hydrolytic enzymatic activities. Polysaccharides released during autolysis are thought to exert a significant effect on the sensory qualities of wine. We studied the chemical composition of polyphenolic compounds remaining in solution or adsorbed on yeast lees after various contact times during the simulation of wine aging. The analysis of the remnant polyphenols in the wine indicated that wine polyphenols adsorption on yeast lees follows biphasic kinetics. An initial and rapid fixation is followed by a slow, constant, and saturating fixation that reaches its maximum after about 1 week. Only very few monomeric phenolic compounds remained adsorbed on yeast lees, and no preferential adsorption of low or high polymeric size tannins occurred. The remnant condensed tannins in the wine contained fewer epigallocatechin units than the initial tannins, indicating that polar condensed tannins were preferentially adsorbed on yeast lees. Conversely, the efficiency of anthocyanin adsorption on yeast lees was unrelated to its polarity.

    Full Text Available The effect of red wine phenolic extracts on the stability of wine volatile esters and terpenes was examined. Muscat (white and Xinomavro (red wines were enriched with each extract at 120 or 200 mg/L, and stored in open bottles at 20 °C for 3 and 2.5 days, respectively. Moreover, a model wine medium containing isoamyl acetate, ethyl hexanoate and linalool was enriched with each extract at 100 mg/L, and stored in sealed bottles at 20 °C for 45–90 days. All samples were analysed for volatiles using SPME along with GC-MS analysis. Phenolic composition of wine extracts was determined using HPLC-DAD. No effect on the concentration of any volatiles was observed as a result of the addition of each extract in each wine or the model medium. A wine extract rich in phenolic acids and another one rich in anthocyanins and flavanols inhibited the decrease of volatile esters and terpenes in one or both wines and the model medium. Among them were several important for the aroma of wine such as ethyl acetate, isoamyl acetate, ethyl hexanoate, ethyl octanoate, ethyl decanoate and linalool. The results presented here indicate that wine phenolic acids, and anthocyanins or flavanols may be taken into account as potent inhibitors of the disappearance of volatile esters and terpenes in wines.

    Differences in mineral concentrations were examined among three types of wine in the Japanese market place: Japan wine, imported wine, and domestically produced wine mainly from foreign ingredients (DWF), where Japan wine has been recently defined by the National Tax Agency as domestically produced wine from grapes cultivated in Japan. The main objective of this study was to examine the possibility of controlling the authenticity of Japan wine. The concentrations of 18 minerals (Li, B, Na, Mg, Si, P, S, K, Ca, Mn, Co, Ni, Ga, Rb, Sr, Mo, Ba, and Pb) in 214 wine samples were determined by inductively coupled-plasma mass spectrometry (ICP-MS) and ICP-atomic emission spectrometry (ICP-AES). In general, Japan wine had a higher concentration of potassium and lower concentrations of eight elements (Li, B, Na, Si, S, Co, Sr, and Pb) as compared with the other two groups of wine. Linear discriminant analysis (LDA) models based on concentrations of the 18 minerals facilitated the identification of three wine groups: Japan wine, imported wine, and DWF with a 91.1% classification score and 87.9% prediction score. In addition, an LDA model for discrimination of wine from four domestic geographic origins (Yamanashi, Nagano, Hokkaido, and Yamagata Prefectures) using 18 elements gave a classification score of 93.1% and a prediction score of 76.4%. In summary, we have shown that an LDA model based on mineral concentrations is useful for distinguishing Japan wine from other wine groups, and can contribute to classification of the four main domestic wine-producing regions of Japan.

    Full Text Available Men have been using herbal medicines for thousands of years. The advantages of this type of therapeutics include good availability, local cultural aspects, individual preferences, the increasing demand for natural and organic products, and the already validated synergistic effects of herbal medicines. However, ethically, the scope and limits of these drugs need to be established not only by ethnopharmacological evidences but also by scientific investigations, which confirm the therapeutic effects. With this study, we propose to discuss the possible advantages of using herbal medicines instead of purified compounds, the truth and myths about herbal medicines, drug discovery, and the implications for medical education and health care.

  16. Herbal medicines for children: an illusion of safety?

    2001-04-01

    Herbal medicaments are in common use. In general, the judicious use of carefully selected and prepared herbal medications seems to cause few adverse effects and may be beneficial. However, toxic effects of these products have been reported with increasing frequency. Infants and children may be even more susceptible to some of the adverse effects and toxicity of these products because of differences in physiology, immature metabolic enzyme systems, and dose per body weight. Although information promoting the use of herbal medicine is widespread, true evidence-based information about the efficacy and safety of herbal medications is limited. Although the most conservative approach is to recommend against use of herbal medicine until such evidence is available, some patients are not receptive to this approach. A reasonable approach for health care providers may be to follow such use closely, assist in herbal therapeutic decisions, and monitor for adverse effects and interactions. This manuscript discusses general concepts about herbal medicines, public health implications, and a framework for mechanisms of adverse effects from the use of botanicals. Adverse effects and toxicity of selected herbal products, including Chinese herbal medicines, are presented. The authors propose a risk reduction approach in which physicians actively seek information about the use of complementary or alternative medicine while taking medical histories.

    Herbal spa treatments are favorite recreational activities throughout the world. The water in spas is often disinfected to control pathogenic microorganisms and guarantee hygiene. However, chlorinated water may cause the formation of disinfection byproducts (DBPs). Although there have been many studies on DBP formation in swimming pools, the role of organic matter derived from herbal medicines applied in herbal spa water has been largely neglected. Accordingly, the present study investigated the effect of herbal medicines on the formation of trihalomethanes (THMs) in simulated herbal spa water. Water samples were collected from a spa pool, and then, disinfection and herbal addition experiments were performed in a laboratory. The results showed that the organic molecules introduced by the herbal medicines are significant precursors to the formation of THMs in spa pool water. Since at least 50% of THMs were produced within the first six hours of the reaction time, the presence of herbal medicines in spa water could present a parallel route for THM exposure. Therefore, despite the undeniable benefits of herbal spas, the effect of applied herbs on DBP formation in chlorinated water should be considered to improve the water quality and health benefits of spa facilities.

    2017-06-01

    Full Text Available The present study examines the perceptions that French, Italian and Spanish consumers have about the possible health effects of what they consider to be a moderate wine consumption. Furthermore, it identifies whether the following factors positively or negatively influence consumer opinion – wine appreciation, environmental awareness, environmental labels, local legislation and media coverage. Perceptions were identified through an online survey of 1183 respondents. The respondents perceive wine as a rather healthy product if consumed moderately. Wine appreciation positively influences the perception of a healthy effect of moderate wine consumption. French policies advising constraints on wine consumption indirectly influence consumer opinion about the unhealthy effects caused by wine. French and Spanish consumers with high environmental awareness perceive a wine with an eco-label to be healthier than a conventional one.
