    The medicinal plants from genus Berberis are particularly important in traditional medicine and the food basket of Iranians. Given various plants from genus Berberis and their economic, nutritional, and medicinal status in Iran, this study seeks to investigate the findings of recent studies on the phytochemical characteristics, specifications, and uses of Berberis vulgaris. In this review article, 350 articles were initially retrieved from reliable scientific databases using relevant search terms. Then, 230 articles were selected and 120 were excluded after a primary analysis. Finally, 98 articles related to the subject under study were meticulously examined and the required data were extracted and classified according to the research purposes. The findings were divided into eight separate sections: Introducing Berberidaceae family, different species of Berberis, pharmaceutical organs, B. vulgaris nutrition facts and minerals, the antioxidants and alkaloids compounds in fruit and other organs, action mechanisms of preventing and treating diseases, traditional uses of B. vulgaris, and its properties reported by recent studies. The results briefly indicate that B. vulgaris contains a large number of phytochemical materials including ascorbic acid, vitamin K, several triterpenoids, more than 10 phenolic compounds and more than 30 alkaloids. Therefore B. vulgaris may have anti-cancer, anti-inflammatory, antioxidant, antidiabetic, antibacterial, analgesic and anti-nociceptive and hepato-protective effects. Regarding the use of different organs of B. vulgaris in traditional medicine and their confirmed effects in the recent studies, it is possible to use different organs of B. vulgaris, especially fruit, to develop new drugs.

    The genus Berberis (Berberidaceae) includes about 500 species worldwide, some of which are widely cultivated in the north-eastern regions of Iran. This genus consists of spiny deciduous evergreen shrubs, characterized by yellow wood and flowers. The cultivation of seedless barberry in South Khorasan goes back to two hundred years ago. Medicinal properties for all parts of these plants have been reported, including: Antimicrobial, antiemetic, antipyretic, antioxidant, anti-inflammatory, anti-arrhythmic, sedative, anti-cholinergic, cholagogic, anti-leishmaniasis, and anti-malaria. The main compounds found in various species of Berberis, are berberine and berbamine. Phytochemical analysis of various species of this genus revealed the presence of alkaloids, tannins, phenolic compounds, sterols and triterpenes. Although there are some review articles on Berberis vulgaris (as the most applied species), there is no review on the phytochemical and pharmacological activities of other well-known species of the genus Berberis. For this reason, the present review mainly focused on the diverse secondary metabolites of various species of this genus and the considerable pharmacological and biological activities together with a concise story of the botany and cultivation.

    2007-01-01

    From the aerial parts of Berberis sibirica Pall. 6 isoquinoline alkaloids of protoberberine, protopine, benzphenanthridine and proaporphine type were isolated. The known alkaloids (-)-tetrahydropseudocoptisine, pseudoprotopine, (+)-chelidonine and (+)-glaziovine are new for the family Berberidaceae. From the roots of B. sibirica 10 isoquinoline alkaloids of protoberberine, benzylisoquinoline, bisbenzylisoquinoline, aporphine-benzylisoquinoline and proaporphine-benzylisoquinoline type were isolated. 1,10-Di-O-methylpakistanine has been reported for the first time as a natural alkaloid. The known alkaloids (-)-isothalidezine and (+)-armepavine have been found for the first time in the family Berberidaceae. All structures were determined by physical and spectral data. (authors)

  6. Taxonomic and phytogeographic implications from ITS phylogeny in Berberis (Berberidaceae).

    Kim, Young-Dong; Kim, Sung-Hee; Landrum, Leslie R

    2004-06-01

    A phylogeny based on the internal transcribed spacer (ITS) sequences from 79 taxa representing much of the diversity of Berberis L. (four major groups and 22 sections) was constructed for the first time. The phylogeny was basically congruent with the previous classification schemes at higher taxonomic levels, such as groups and subgroups. A notable exception is the non-monophyly of the group Occidentales of compound-leaved Berberis (previously separated as Mahonia). At lower levels, however, most of previous sections and subsections were not evident especially in simple-leaved Berberis. Possible relationship between section Horridae (group Occidentales) and the simple-leaved Berberis clade implies paraphyly of the compound-leaved Berberis. A well-known South America-Old World (mainly Asia) disjunctive distribution pattern of the simple-leaved Berberis is explained by a vicariance event occurring in the Cretaceous period. The ITS phylogeny also suggests that a possible connection between the Asian and South American groups through the North American species ( Berberis canadensis or B. fendleri) is highly unlikely.

    2017-11-01

    Full Text Available Background: Berberis aristata occupies significant position as a medicinal plant. Given its clinical applications and the grave concern of weed based crop damage in Pakistan, the plant was investigated for its antimicrobial and allelopathic activities. Methods: Fresh Berberis aristata plant was obtained from Rawalakot and Hajeera (District Poonch Azad Kashmir. Methanolic extract preparation and phytochemical analysis was done using standard procedures. Antibacterial and antifungal activities of the root, stem and leaf extracts of the plant were assayed against the bacterial strains E. coli, S. typhi, S. aureus, Shigella, Citrobacter, P. vulgaris, Enterobacter, S. pyrogenes, V. cholera and Klebsiella spp. and fungal strains A. niger, Cladosporium, Rhizoctonia, Alternaria, Trichoderma, Penicillium, Curvularia, Paecilomyces and Rhizopus using disc diffusion method. Also, the phytoxicity of the extracts was evaluated against Lemna minor and the data was recorded after seven days. Results: Phytochemical screening of the three extracts identified the presence of alkaloids, reducing sugars, steroids, flavonoids, terpenoids, glycosides and saponins while tannins were found to be absent. The leaf extract also showed negative tests for alkaloids and steroids. The extracts significantly inhibited the growth of the employed microbial isolates. The leaf extract, however, was not active against A. niger, Curvularia, Paecilomyces and Rhizopus. For most of the tested strains, the effectiveness of the extracts was much higher than that of Amoxicillin and Fluconazole; the positive controls used for bacterial and fungal cultures, respectively. All the extracts demonstrated 100% phytotoxicity against Lemna minor at 1000 μg/mL while low activity (10-20% was observed at 10 μg/mL and 100 μg/mL, respectively. Conclusion: The results strongly support the profound ethnobotanical applications of this plant and also demonstrate its potential for use in weed control

    Southern barberry or calafate (Berberis microphylla) is a shrub species endemic to the Patagonian region of South America that is used for human consumption. The fruit is very rich in vitamin C and anthocyanins and has a very high antioxidant capacity. There have been only a few genetic studies of this and other closely related species. • Here we present the first 18 microsatellite markers of B. microphylla that were characterized using 66 accessions of calafate from Patagonia. On average, they had 7.6 alleles per marker, with an expected heterozygosity of 0.688. The informativeness of these markers was also evaluated in another 15 Berberis species, including most of the native and endemic Chilean species. • The results confirm that these new simple sequence repeat markers are very polymorphic and potentially useful in genetic studies in any species of the genus Berberis.

    2015-01-01

    Berberis is an important genus and well known in the Indian as well as European systems of traditional medicine. It is used since ancient times for curing eye disease, fever, jaundice, rheumatism, vomiting during pregnancy, kidney and gall balder stones and various other ailments due to the presence of biologically active alkaloid berberine. Action of the root extracts of few species are believed to be as powerful as quinine in the treatment of malarial fever. A plethora of literature pertaining to the taxonomy, biology, chemistry, traditional and ethnic uses of Berberis in different countries and indigenous cultures was collected by both offline (library, journals, textbooks etc.) and online mode (electronic search of available databases). In addition to this, books on traditional medicine and ethno pharmacological knowledge were also referred to extract ancient uses of Berberis in different traditional medicine systems. Most of the folklore, traditional and ethno botanical claims about Berberis species were validated by broad spectrum in vitro and vivo pharmacological studies. The present article summarizes its usage in eye and liver disorder, fever, kidney and gall stones along with anticancer activity. This comprehensive review will not only help researchers for further evaluation but also provide substantial information for future exploitation of species to develop novel herbal formulations.

    2006-08-01

    Bulimia nervosa is characterized by episodes of binge eating and compensatory behaviours (self-induced vomiting, laxative misuse, dietary restriction). It has a complex aetiology and is mostly found in young women. Bulimia leads to substantial physical and psychosocial morbidity. Bulimia nervosa needs specialized psychotherapeutic treatment. In most cases outpatient treatment is sufficient, but comorbidity with other psychiatric disturbances has to be taken into account. Additional psychopharmacological interventions might be helpful. After 5 to 10 years about 50% of the patients show complete remissions, 30% partial remissions and about 20% a chronic course of the illness. General practitioners, dentists and gynaecologists should be informed about typical signs of the disorder that is often hidden by the patients.

  6. Detecting the influence of ornamental Berberis thunbergii var. atropurpurea in invasive populations of Berberis thunbergii (Berberidaceae) using AFLP1.

    Lubell, Jessica D; Brand, Mark H; Lehrer, Jonathan M; Holsinger, Kent E

    2008-06-01

    Japanese barberry (Berberis thunbergii DC.) is a widespread invasive plant that remains an important landscape shrub represented by ornamental, purple-leaved forms of the botanical variety atropurpurea. These forms differ greatly in appearance from feral plants, bringing into question whether they contribute to invasive populations or whether the invasions represent self-sustaining populations derived from the initial introduction of the species in the late 19th century. In this study we used amplified fragment length polymorphism (AFLP) markers to determine whether genetic contributions from B. t. var. atropurpurea are found within naturalized Japanese barberry populations in southern New England. Bayesian clustering of AFLP genotypes and principal coordinate analysis distinguished B. t. var. atropurpurea genotypes from 85 plants representing five invasive populations. While a single feral plant resembled B. t. var. atropurpurea phenotypically and fell within the same genetic cluster, all other naturalized plants sampled were genetically distinct from the purple-leaved genotypes. Seven plants from two different sites possessed morphology consistent with Berberis vulgaris (common barberry) or B. ×ottawensis (B. thunbergii × B. vulgaris). Genetic analysis placed these plants in two clusters separate from B. thunbergii. Although the Bayesian analysis indicated some introgression of B. t. var. atropurpurea and B. vulgaris, these genotypes have had limited influence on extant feral populations of B. thunbergii.

    Allen, Jenica M; Obae, Samuel G; Brand, Mark H; Silander, John A; Jones, Kenneth L; Nunziata, Schyler O; Lance, Stacey L

    2012-05-01

    Microsatellite markers were isolated and characterized in Berberis thunbergii, an invasive and ornamental shrub in the eastern United States, to assess genetic diversity among populations and potentially identify horticultural cultivars. A total of 12 loci were identified for the species. Eight of the loci were polymorphic and were screened in 24 individuals from two native (Tochigi and Ibaraki prefectures, Japan) and one invasive (Connecticut, USA) population and 21 horticultural cultivars. The number of alleles per locus ranged from three to seven, and observed heterozygosity ranged from 0.048 to 0.636. These new markers will provide tools for examining genetic relatedness of B. thunbergii plants in the native and invasive range, including phylogeographic studies and assessment of rapid evolution in the invasive range. These markers may also provide tools for examining hybridization with other related species in the invasive range.

  10. Berberis vulgaris for cardiovascular disorders: a scoping literature review

    Abdelrahman Abushouk

    2017-05-01

    Full Text Available Cardiovascular disorders are the leading cause of mortality worldwide. Berberis vulgaris (B. vulgaris is a commonly used plant in traditional medicine. In recent studies, B. vulgaris showed antiarrhythmic, antihypertensive, anticholinergic, and cardioprotective effects. We reviewed the literature to explore the possible prophylactic and therapeutic roles of B. vulgaris in cardiovascular medicine. A computer literature search was conducted to identify all relevant studies that have investigated the role of B. vulgaris in prevention or treatment of cardiovascular diseases.We also searched the citations of the retrieved articles. Using a systematic approach, we conducted a scoping review that included a total of 37 articles. Twelve studies examined the antihypertensive effects of B. vulgaris, seven studies investigated its antiarrhythmic effects, while its inotropic and cardioprotective effects were evaluated in four and eight studies, respectively. B. vulgaris showed a beneficial effect in reducing blood pressure, enhancing cardiac contractility, and protection from reperfusion injury. However, the mechanisms of these effects are still under investigation. Moreover, it could modify major risk factors for cardiovascular disorders, such as oxidative stress, hyperglycemia, and hyperlipidemia. Further studies are needed to translate these findings into effective cardiovascular medications.

    2013-01-01

    Full Text Available Background: Berberis aristata DC (Berberidaceae commonly known in Hindi as "Dāruhaldi" and "Citra," is an important medicinal herb native to Northern Himalaya region. The plant is used traditionally in Indian system of medicine as an antibacterial, antiperiodic, antidiarrheal and anticancer and it is also used in the treatment of ophthalmic infections. Its root, stem and leaves also find their use in treatment of various ailments and hence is used extensively in Ayurveda. Materials and Methods: Samples of the whole plants of B. aristata were collected and identified. Hand and microtome sections were taken, stained and mounted and the cell content and cell wall structure were studied according to the method described by Kay and Johansen. Representative sketches were made with the help of camera Lucida. Methods for determining the quantitative values were the same as described elsewhere. For fluorescence analysis, the powder of the root, stem and leaf were examined under ultraviolet light. Total ash, acid insoluble ash and water-soluble ash values and water- and alcohol-soluble extractives were determined. Results: The detailed investigations carried on the pharmacognosy of the root; stem and leaf of B. aristata have brought out some salient diagnostic features, which allow one to differentiate it from other substitutes and or adulterants. The determination of quantitative values, fluorescence analysis and the use of lycopodium spore analysis has specifically contributed to this differentiation. Conclusion: From the foregoing observation on the pharmacognosy of root, stem and leaf of B. aristata DC, the salient diagnostic characters of three parts have been presented, which can allow one to differentiate it from other substitutes and or adulterants.

    There are 20 species of the Berberidaceae family described in Chile, whose fruits are edible and show high anthocyanin and hydroxycinnamic acid levels. Berberis microphylla G. Forst, commonly known as calafate, is the most extensively distributed. Flavonols and alkaloids in seed, pulp, skin, and whole calafate berry extracts and other Berberis were studied using HPLC-DAD-ESI-MS/MS and HPLC with fluorescence detector. Berry samples from different locations in Chilean Patagonia, including different phenological stages, were systematically addressed. Results were compared with other organs of the plant and with other Berberis species. Total flavonol concentration in calafate (n = 65) was 1.33 ± 0.54 μmol/g. Glycosyl metabolites of quercetin and isorhamnetin were the most abundant. Similar profiles were observed in calafate from distinct locations, but important differences were observed for the other edible Berberis species. Calafate pulp and skin have higher flavonol concentrations than seeds, and the maturation process reduced its levels. TEACCUPRAC and TEACABTS of whole calafate extracts and fractions are also explored. Finally, only berberine was detected in the fruit (0.001%), mainly in seeds. Results contribute to the promotion of this berry as a superfruit from Patagonia.

  18. Anorexia Nervosa/Atypical Anorexia Nervosa.

    Moskowitz, Lindsay; Weiselberg, Eric

    2017-04-01

    Anorexia nervosa has the highest mortality rate among all psychiatric illnesses, as it can result in significant psychopathology along with life-threatening medical complications. Atypical anorexia nervosa is a new variant described in the latest DSM edition, which has much in common with anorexia nervosa and also can result in significant morbidity and mortality. The evolution of the criteria for these illnesses is reviewed, and the two are compared and contrasted in this article. Important labs to monitor for in those with these illnesses, along with an emphasis on the monitoring of vital signs and weight, are reviewed here. The necessity for close psychiatric monitoring of safety concerns, including suicidal thoughts, is also stressed. The etiology and the treatment of these illnesses are reviewed from a biopsychosocial approach; and lastly, the prognosis of these illnesses is discussed. Copyright © 2017.

    Meng, Jiang-Fei; Shi, Tian-Ci; Song, Shuo; Zhang, Zhen-Wen; Fang, Yu-Lin

    2017-09-15

    A decade has passed since melatonin was first reported in grapes in 2006. During this time, melatonin has not only been found in the berries of most wine grape (Vitis vinifera L.) cultivars, but also in most grape-related foodstuffs, e.g. wine, grape juice and grape vinegar. In this review, we discuss the melatonin content in grapes and grape-related foodstuffs (especially wine) from previous studies, the physiological function of melatonin in grapes, and the factors contributing to the production of melatonin in grapes and wines. In addition, we identify future research needed to clarify the mechanisms of grape melatonin biosynthesis and regulation, and establish more accurate analysis methods for melatonin in grapes and wines.

    2015-01-01

    Inherent to anorexia nervosa and bulimia nervosa are a plethora of medical complications which correlate with the severity of weight loss or the frequency and mode of purging. Yet, the encouraging fact is that most of these medical complications are treatable and reversible with definitive care and cessation of the eating-disordered behaviours. Herein, these treatments are described for both the medical complications of anorexia nervosa and those which are a result of bulimia nervosa.

  4. Cardiac changes in anorexia nervosa.

    Spaulding-Barclay, Michael A; Stern, Jessica; Mehler, Philip S

    2016-04-01

    Introduction Anorexia nervosa is an eating disorder, which is associated with many different medical complications as a result of the weight loss and malnutrition that characterise this illness. It has the highest mortality rate of any psychiatric disorder. A large portion of deaths are attributable to the cardiac abnormalities that ensue as a result of the malnutrition associated with anorexia nervosa. In this review, the cardiac complications of anorexia nervosa will be discussed. A comprehensive literature review on cardiac changes in anorexia nervosa was carried out. There are structural, functional, and rhythm-type changes that occur in patients with anorexia nervosa. These become progressively significant as ongoing weight loss occurs. Cardiac changes are inherent to anorexia nervosa and they become more life-threatening and serious as the anorexia nervosa becomes increasingly severe. Weight restoration and attention to these cardiac changes are crucial for a successful treatment outcome.

    Full Text Available Grape surface is an unstable habitat that changes greatly according to the stage of grape ripening. Different bacteria and yeasts can colonise the surface of grape berry and the diversity of microorganisms depends on the stage of ripening, pesticide application and health condition. The aim of this study was to study the microflora of the surface of grape berries. Altogether, 19 grape samples from Slovakia were collected. The spread plate method was applied and a 100 μL inoculum of each dilution (10−2, 10−3 was plated on TSA, MEA, and MRS agar for isolation of microorganisms from grapes. Proteins were extracted from cells by ethanol/formic acid extraction procedure. MALDI-TOF Mass Spectrometry was used for identification of microorganisms. In total, 11 genera of Gram-negative bacteria, 11 of Gram-positive bacteria and nine of yeasts were identified. Among 200 isolates, Gram-negative, Gram-positive bacteria and yeasts represented 11%, 27% and 62% of the total number of isolates studied. The most common genera of isolated yeasts were Hanseniaspora (37%, Metschnikowia (31%, and Rhodotorula (10%. The most frequently isolated among Gram-negative bacteria were Acinetobacter (22%, Pseudomonas (22% and Sphingomonas (13%. The most common genera of Gram-positive bacteria were Bacillus (20%, Lactobacillus (19%, Leuconostoc and Staphylococcus (11%, respectively.

    Background The concept of DNA barcoding for species identification has gained considerable momentum in animals because of fairly successful species identification using cytochrome oxidase I (COI). In plants, matK and rbcL have been proposed as standard barcodes. However, barcoding in complex genera is a challenging task. Methodology and Principal Findings We investigated the species discriminatory power of four reportedly most promising plant DNA barcoding loci (one from nuclear genome- ITS, and three from plastid genome- trnH-psbA, rbcL and matK) in species of Indian Berberis L. (Berberidaceae) and two other genera, Ficus L. (Moraceae) and Gossypium L. (Malvaceae). Berberis species were delineated using morphological characters. These characters resulted in a well resolved species tree. Applying both nucleotide distance and nucleotide character-based approaches, we found that none of the loci, either singly or in combinations, could discriminate the species of Berberis. ITS resolved all the tested species of Ficus and Gossypium and trnH-psbA resolved 82% of the tested species in Ficus. The highly regarded matK and rbcL could not resolve all the species. Finally, we employed amplified fragment length polymorphism test in species of Berberis to determine their relationships. Using ten primer pair combinations in AFLP, the data demonstrated incomplete species resolution. Further, AFLP analysis showed that there was a tendency of the Berberis accessions to cluster according to their geographic origin rather than species affiliation. Conclusions/Significance We reconfirm the earlier reports that the concept of universal barcode in plants may not work in a number of genera. Our results also suggest that the matK and rbcL, recommended as universal barcode loci for plants, may not work in all the genera of land plants. Morphological, geographical and molecular data analyses of Indian species of Berberis suggest probable reticulate evolution and thus barcode markers may

    Zayed, Moaweya; Garry, Joseph P

    2017-01-01

    Eating disorders are not commonly diagnosed in individuals aged >50 years, yet they are associated with significant psychiatric comorbidities and overall morbidity. Anorexia nervosa is the most common eating disorder among this age group, and women are affected most often. We present the fatal case of a 66-year old woman with severe malnutrition and newly diagnosed anorexia nervosa. Inpatient refeeding was unsuccessful, and she succumbed to multisystem organ failure. The timely recognition of eating disorders among older people is important for family physicians who care for patients across the life spectrum. © Copyright 2017 by the American Board of Family Medicine.

  15. Interpersonal psychotherapy for anorexia nervosa.

    McIntosh, V V; Bulik, C M; McKenzie, J M; Luty, S E; Jordan, J

    2000-03-01

    This paper outlines the rationale for treating individuals with anorexia nervosa using interpersonal psychotherapy. We review theoretical, empirical, and psychotherapy literature relating to interpersonal functioning in anorexia nervosa. Etiological theories emphasize interpersonal and family dysfunction in the development of anorexia nervosa. Research supports the notion that families of individuals with anorexia nervosa have dysfunctional patterns of communication. The history of treatment for anorexia nervosa emphasizes the need for resolution of interpersonal dysfunction, within the traditions of psychodynamic, family therapy, and multidimensional therapies. Interpersonal psychotherapy is a time-limited psychotherapy based on the notion that regardless of etiology, interpersonal relationships are intertwined with symptomatology. The goals of the therapy are to improve interpersonal functioning and thereby decrease symptomatology. Factors identified as important in the development of anorexia nervosa are readily conceptualized within the interpersonal psychotherapy problem areas of grief, interpersonal disputes, interpersonal deficits, and role transitions.

  17. Effect of Moisture Content on Mechanical Properties and Terminal Velocity of Berberis

    E Velayati

    2011-09-01

    Full Text Available The study of mechanical properties of Berberis not only is useful for design and optimization of transportation, processing and packaging equipment but also can prevent mechanical injuries and losses. In this study force, deformation, energy and toughness were measured at different moisture content levels including 70-76, 45-50, 25-30 and 7-10 percent (w.b.. The decrease of moisture content caused increasing rupture force from 1.387 to 2.679 N, decreasing shape deformation from 3.387 to 2.413mm, increasing toughness from 4.297 to 8.220 J/cm3 and decreasing rupture energy from 0.921 to 0.661mJ. Effects of loading speed, force orientation and their interaction were investigated on just fresh Berberis fruit. It was indicated that only force orientation was effective on all investigated properties except toughness. The moisture content was identified as an effective parameter on terminal velocity. It decreased from 9 to 4.5 m/s with decrease of moisture content from 76 to 7 percent (w.b..

  1. Anorexia and bulimia nervosa.

    Kaye, W H; Klump, K L; Frank, G K; Strober, M

    2000-01-01

    Anorexia nervosa (AN) and bulimia nervosa (BN) are disorders characterized by abnormal patterns of weight regulation and eating behavior and by disturbances in attitudes and perceptions toward weight and body shape. Etiologic research has indicated substantial genetic influence on these disorders, suggesting significant biological contributions to their development. Obsessional, perfectionistic, and anxious personality styles may be premorbid traits that contribute to this pathogenesis. Studies of neuroendocrine, neuropeptide, and neurotransmitter functioning in patients with AN and BN indicate that disturbances of these systems may contribute to the maintenance as well as the etiology of these sometimes fatal disorders. The efficacy of psychological treatments and pharmacotherapy has been more clearly established for BN than for AN.

  2. Bulimia Nervosa/Purging Disorder.

    Castillo, Marigold; Weiselberg, Eric

    2017-04-01

    Bulimia nervosa was first described in 1979 by British psychiatrist Gerald Russell as a "chronic phase of anorexia nervosa" in which patients overeat and then use compensatory mechanisms, such as self-induced vomiting, laxatives, or prolonged periods of starvation. The characterization of bulimia nervosa continues to evolve with the introduction of the DSM-5 in 2013. In this article, the epidemiology and risk factors of bulimia nervosa are identified and reviewed, along with the medical complications and psychiatric comorbidities. The evaluation of a patient with suspected bulimia nervosa is addressed, with an emphasis on acquiring a complete and thorough history as well as discovering any comorbidities that are present. Management of the patient involves both medical interventions and behavioral counseling in order to address physical, psychological, and social needs. Lastly, a new diagnosis introduced in the DSM-5, purging disorder, is described and discussed. Copyright © 2017 Mosby, Inc. All rights reserved.

  6. Dopamine and anorexia nervosa.

    Södersten, P; Bergh, C; Leon, M; Zandian, M

    2016-01-01

    We have suggested that reduced food intake increases the risk for anorexia nervosa by engaging mesolimbic dopamine neurons, thereby initially rewarding dieting. Recent fMRI studies have confirmed that dopamine neurons are activated in anorexia nervosa, but it is not clear whether this response is due to the disorder or to its resulting nutritional deficit. When the body senses the shortage of nutrients, it rapidly shifts behavior toward foraging for food as a normal physiological response and the mesolimbic dopamine neurons may be involved in that process. On the other hand, the altered dopamine status of anorexics has been suggested to result from a brain abnormality that underlies their complex emotional disorder. We suggest that the outcomes of the treatments that emerge from that perspective remain poor because they target the mental symptoms that are actually the consequences of the food deprivation that accompanies anorexia. On the other hand, a method that normalizes the disordered eating behavior of anorexics results in much better physiological, behavioral, and emotional outcomes. Copyright © 2015 Elsevier Ltd.

  7. PSYCHOPATHOLOGICAL ASPECTS OF ANOREXIA NERVOSA

    A. E. Bobrov

    2015-01-01

    Full Text Available Prevalence of anorexia nervosa among women is 0,5%, whereas mortality related to this disorder amounts to 5–17%. Psychopathological structure of anorexia nervosa implies abnormalities of behavior as well as those of motivation and volition, thinking, perception and appreciation. In addition, mental abnormalities typical for this disorder are evident in regulation of emotions, specific personality traits and self-consciousness. The key psychopathological feature of patients with anorexia nervosa is a lack of cognitive and personal differentiation that calls forth impairments of self-concept and self-image. Anorexia nervosa should be differentiated from depression and schizophrenic spectrum disorders. Its etiology and pathogenesis are related both to hereditary and psychosocial factors. Of great importance are psychoendocrine abnormalities, however their role is still insufficiently elucidated.

  8. Combination chemoprevention with grape antioxidants.

    Singh, Chandra K; Siddiqui, Imtiaz A; El-Abd, Sabah; Mukhtar, Hasan; Ahmad, Nihal

    2016-06-01

    Antioxidant ingredients present in grape have been extensively investigated for their cancer chemopreventive effects. However, much of the work has been done on individual ingredients, especially focusing on resveratrol and quercetin. Phytochemically, whole grape represents a combination of numerous phytonutrients. Limited research has been done on the possible synergistic/additive/antagonistic interactions among the grape constituents. Among these phytochemical constituents of grapes, resveratrol, quercetin, kaempferol, catechin, epicatechin, and anthocyanins (cyanidin and malvidin) constitute more than 70% of the grape polyphenols. Therefore, these have been relatively well studied for their chemopreventive effects against a variety of cancers. While a wealth of information is available individually on cancer chemopreventive/anti-proliferative effects of resveratrol and quercetin, limited information is available regarding the other major constituents of grape. Studies have also suggested that multiple grape antioxidants, when used in combination, alone or with other agents/drugs show synergistic or additive anti-proliferative response. Based on strong rationale emanating from published studies, it seems probable that a combination of multiple grape ingredients alone or together with other agents could impart 'additive synergism' against cancer. © 2016 WILEY-VCH Verlag GmbH & Co.

    Misra, Madhusmita; Klibanski, Anne

    2013-01-01

    Purpose of review Anorexia nervosa is associated with low bone mineral density (BMD), concerning for an increased risk of fractures, and decreased bone accrual in adolescents, concerning for suboptimal peak bone mass. This review discusses causes of impaired bone health in anorexia nervosa and potential therapeutic strategies. Recent findings Low BMD in anorexia nervosa is consequent to decreased lean mass, hypogonadism, low insulin-like growth factor-1 (IGF-1), relative hypercortisolemia and alterations in hormones impacted by energy availability. Weight gain causes some improvement in bone accrual, but not to the extent observed in controls, and vitamin D supplementation does not increase BMD. Oral estrogen is not effective in increasing BMD, likely from IGF-1 suppressive effects. In contrast, transdermal estrogen replacement is effective in increasing bone accrual in adolescents with anorexia nervosa, although not to the extent seen in controls. Recombinant human IGF-1 increases bone formation in adolescents, and with oral estrogen increases BMD in adults with anorexia nervosa. Bisphosphonates increase BMD in adults, but not in adolescents, and should be used cautiously given their long half-life. Summary Further investigation is necessary to explore therapies for low BMD in anorexia nervosa. Weight gain is to be encouraged. Transdermal estrogen in adolescents, and bisphosphonates in adults, have a potential therapeutic role. PMID:21897220

  12. Starting from grape cultivation.

    Yoshida, A

    1992-06-01

    Rapid population growth can only be stopped by lowering the fertility rate. The UNFPA recommends improving the employment opportunities for women as the single best way of achieving this reduction. An example of this phenomenon is the grape cultivation in the Nordeste (Northeastern) region of Brazil. This area is the poorest part of Brazil and has the highest proportion of indigent people. These people have been deforesting the Amazon in search of a better life. What they have done is sterilize the land and turned a tropical rain forest into a desert. In an effort to reverse this trend, grape cultivation has been introduced in an area called Petrolina. The area is very dry with less than 500 mm of precipitation annually. They do have access to a 5000 square kilometer artificial lake (the largest in the world) and the 3rd largest river in Brazil (the Sao Francisco). In an effort to avoid using agricultural medicines, the vines are fertilized with organic matter created on the farm and little or no pesticides are used since pests do not live in such an arid region. It has taken 20 years of trial and error, but the quality of the grapes is now very high and is competitive on the world market. Because of climate and location, harvesting is done year round which increases the productivity of the land. The farm managers have found that married women make the best workers and have the highest level of productivity. Age at 1st marriage averages 24-25, compared with 15-16 for unemployed women in the same area. The fertility rate averages 50% of that for unemployed women in the same area. Agricultural development offers the best opportunity for the women of developing countries. It can pay a high wage, reduce fertility, and replant desert areas.

  13. Diagnostic Crossover in Anorexia Nervosa and Bulimia Nervosa: Implications for DSM-V

    Eddy, Kamryn T.; Dorer, David J.; Franko, Debra L.; Tahilani, Kavita; Thompson-Brenner, Heather; Herzog, David B.

    2011-01-01

    Objective The Diagnostic and Statistical Manual of Mental Disorders (DSM) is designed primarily as a clinical tool. Yet high rates of diagnostic “crossover” among the anorexia nervosa subtypes and bulimia nervosa may reflect problems with the validity of the current diagnostic schema, thereby limiting its clinical utility. This study was designed to examine diagnostic crossover longitudinally in anorexia nervosa and bulimia nervosa to inform the validity of the DSM-IV-TR eating disorders classification system. Method A total of 216 women with a diagnosis of anorexia nervosa or bulimia nervosa were followed for 7 years; weekly eating disorder symptom data collected using the Eating Disorder Longitudinal Interval Follow-Up Examination allowed for diagnoses to be made throughout the follow-up period. Results Over 7 years, the majority of women with anorexia nervosa experienced diagnostic crossover: more than half crossed between the restricting and binge eating/purging anorexia nervosa subtypes over time; one-third crossed over to bulimia nervosa but were likely to relapse into anorexia nervosa. Women with bulimia nervosa were unlikely to cross over to anorexia nervosa. Conclusions These findings support the longitudinal distinction of anorexia nervosa and bulimia nervosa but do not support the anorexia nervosa subtyping schema. PMID:18198267

    2017-05-01

    Full Text Available Berberis vulgaris and berberine, its main component, traditionally have been used for treatment of various disorders. The pharmacological properties of them have been investigated using different in vivo and in vitro models. In spite of beneficial effects of B. vulgaris on different cell lines, there are documents have revealed negative impacts of it on animal and human. In this regards, the determination of its toxicity in a scientific view is necessary. In current report, we provide classified information about the toxicity of B. vulgaris and berberine in different conditions consist of acute, sub-acute, sub-chronic and chronic state. Besides, it discusses the cytotoxicity, genotoxicity, mutagenicity, and carcinogenicity of B. vulgaris and berberine as well as developmental toxicity and clinical studies. Data from the present study indicate that their toxicity is depending on the route and duration of administration. According to present study, they could induce GI upset and ulceration, immunotoxicity, phototoxicity, neurotoxicity, cardiotoxicity and jaundice in a dose dependent manner. They should be used with caution in pregnancy, neonatal and G6PD deficiency. Besides, consideration should be taken in co-administration of berberine with drugs that are metabolized with CYP enzymes due their inhibitory effects on these enzymes. Furthermore, they evoke cytotoxicity on both normal and cancer cell line which is time and concentration dependent.

    2016-04-01

    In this study, the extraction of water-soluble polysaccharides (BDPs) from Berberis dasystachya Maxim using dynamic microwave-assisted extraction (DMAE) was discussed. A Box-Behnken design combined with response surface methodology has been employed to optimize extraction parameters of DMAE. The BDPs have been analyzed in order to identify a variety of chemical properties. Antioxidant and anti-tumor activities in vitro have been studied by DPPH, ABTS, reducing power assay, and MTT assay, respectively. The results obtained showed that the optimal extraction conditions were as follows: ratio of water to raw material (X1) 25.84 mg/L, extraction power (X2) 433.13W, extraction time (X3) 35.18 min, and the maximum yield of extraction was 6.472 ± 0.384%, which was in good agreement with the predicted value. The physicochemical tests demonstrated that the BDPs mainly consist of rhamnose, arabinose, xylose, mannose, glucose and lactose in a molar ratio of 1:17.3:1.33:7:2.33:1.78; the average molecular weight of the BDPs was estimated to be from 2.95×10(5) and 1.52×10(3)Da, respectively. Furthermore, the BDPs exhibited effective antioxidant and anti-proliferative properties in vitro. Such pharmaceutical activities could prove useful for potential future applications involving the berries of B. dasystachya Maxim. Copyright © 2015 Elsevier B.V. All rights reserved.

  19. A quick overview on some aspects of endocrinological and therapeutic effects of Berberis vulgaris L.

    Full Text Available Many herbaceous plants contain compounds that have biological effects in addition to their medicinal properties. They have compounds with numerous properties, including hypo lipidemic, hypoglycemic, antioxidant, and hepato protective ones, which have been analyzed at different levels. One of these plants, with the scientific name of Berberis vulgaris, is barberry. The most important compounds identified in this plant are berberine, oxycontin, palmatine, bervulcine, berbamine, columbamine, jatrorrhizine, coptisine, and berbamine. In addition to alkaloids, organic acids such as chelidonic acid, citric acid, malic acid, resin, tannin, pectinic, and mucilagic substances are among the ingredients of barberry. In this paper, it was attempted to determine the role and effect of the extract of barberry on various body organs. The results showed that berberine actually increases insulin sensitivity and is capable of inhibiting alpha glucosidase, adipogenesis, and thus acts as an anti-obesity and hypoglycemic agent. Berberine reduces the density of serum cholesterol and triglycerides and can improve the function of liver enzymes, therefore, it can be suggested as a hypo lipidemic and hepato protective plant extract. The hepato protective effects of this extract are probably due to its antioxidant properties. Studies showed that barberry have numerous health benefits, including anti-inflammatory ones. Moreover, it can be used as a medicinal herb to treat a variety of disorders, such as diabetes, liver disease, gallbladder pain, digestive, urinary tract diseases, and gallstones. However, more studies on this issue and doing more focused and intensive researches in this field are recommended.

    Dried fruits of Berberis crataegina (Berberidaceae) have been frequently consumed as food garniture in Turkish cuisine, while its fruit paste has been used to increase stamina and in particular to prevent from cardiovascular dysfunctions in Northeastern Black Sea region of Turkey. This study investigated this folkloric information in order to explain the claimed healing effects as well as to evaluate possible risks. Total phenolic, flavonoid and proanthocyanidin contents and antioxidant capacity of the methanolic fruit extract were evaluated through several in vitro assays. The cytotoxic and genotoxic effects of B. crataegina fruit extract were also assessed in both cervical cancer cell line (HeLa) and human peripheral blood lymphocytes. The extract showed protective effects against ferric-induced oxidative stress and had a relatively good antioxidant activity. It also ameliorated the H2O2 mediated DNA damage in lymphocytes, suggesting the protective effect against oxidative DNA damage. The methanolic extract of B. crataegina fruits may be a potential antioxidant nutrient and also may exert a protective role against lipid peroxidation as well as oxidative DNA damage.

    Berberis is known as a medicinal and ornamental plant in the world. Berberis fruit is used in medicine to cure liver, neck and stomach cancer, blood purification and mouth scent. Dried berberis fruit using new technology was preserved for relatively long time. Thin-layer drying simulation was used to obtain experiment data, using laboratory scale hot-air dryer of the static tray. Fick's second law was used as a major equation to calculate the moisture diffusivity with some simplification. The calculated value of moisture diffusivity varied from a minimum of 3.320 x 10{sup -10} to a maximum of 9 x 10{sup -9} m{sup 2}/s and the value of energy activation from a minimum of 110.837 to a maximum of 130.61 kJ/mol of from 50 C to 70 C with drying air velocities of 0.5-2 m/s. The high value of the energy of activation for berberis fruit probably related to the tissue of berberis fruit and high moisture content (about 74.28%w.b), and intensive changes in D{sub eff} values for a different air temperature at constant air velocity. The input energy values and specific energy requirement for thin-drying of berberis fruit were found to be in the range of 0.643348-35.20032 (kWh) and 20.9355-1110.0700 (kWh/kg) from 50 C to 70 C with drying air velocities of 0.5-2 m/s, respectively.

    Anorexia nervosa is an eating disorder among adolescent girls and young women which, though common, often goes undetected and untreated. Anorexia nervosa is a response for young people with psychological conflicts who try to win love by having a body corresponding to the present-day image, symbolising strength, beauty, attraction, power and success. Anorexia nervosa involves inadequate calorie intake leading to marked cachexia with metabolic and endocrinological disturbances. We investigated dermatological changes in 21 young female anorectics aged 19-24 in an attempt to find dermatological markers which mirror the dynamics of the disease and thus obtain helpful signs for early diagnosis with its important bearing on the outcome. Extensive histories were taken and whole-body examinations performed. Seven sex- and age-matched persons served as a control group. The most common dermatological findings were xerosis (71%, controls 29%), cheilitis (76%), bodily hypertrichosis (62%), alopecia (24%), dry scalp hair (48%), acral coldness (38%), acrocyanosis (33%), periungual erythema (48%), gingival changes (37%), nail changes (29%) and calluses on dorsum of hand due to self-induced vomiting (67%). Our study documented for the first time that a body mass index of anorexia nervosa and in HIV infection. Patients with anorexia nervosa develop early stereotype skin changes which are cardinal diagnostic symptoms and pointers to the diagnosis of eating disorders. During training at the Department of Child and Adolescent Psychiatry in Solothurn one of us (C. H.) was once more able to observe most of the above-described cutaneous and mucocutaneous changes in anorexic adolescents. This paper is intended to stimulate further basic research on this topic. We hope our study will facilitate early diagnosis of anorexia nervosa by the family physician and enable him or her to institute immediate treatment for the eating disorder and thereby improve the prognosis.

    Despite a high prevalence of menstrual irregularities, women with anorexia nervosa are becoming pregnant. The physical and psychological demands of pregnancy and motherhood can represent an immense challenge for women already struggling with the medical and psychological stress of an eating disorder. This article summarizes key issues related to reproduction in women with anorexia nervosa, highlighting the importance of preconception counseling, adequate gestational weight gain, and sufficient pre- and post-natal nutrition. Postpartum issues including eating disorder symptom relapse, weight loss, breastfeeding, and risk of perinatal depression and anxiety are also discussed. PMID:22003362

Our study included 117 dietitians (Ankara). Orto-15 test scores below 40 points was considered indicative of orthorexia, while higher scores indicated a normal eating behavior. It was found that participants with ORTO-15 scores less than 40 had higher scores for EAT-40 and MOCI (p orthorexia nervosa is recommended.

  7. Anorexia Nervosa and Bone

    Misra, Madhusmita; Klibanski, Anne

    2014-01-01

    Anorexia nervosa (AN) is a condition of severe low weight that is associated with low bone mass, impaired bone structure and reduced bone strength, all of which contribute to increased fracture risk., Adolescents with AN have decreased rates of bone accrual compared with normal-weight controls, raising addition concerns of suboptimal peak bone mass and future bone health in this age group. Changes in lean mass and compartmental fat depots, hormonal alterations secondary to nutritional factors contribute to impaired bone metabolism in AN. The best strategy to improve bone density is to regain weight and menstrual function. Oral estrogen-progesterone combinations are not effective in increasing bone density in adults or adolescents with AN, and transdermal testosterone replacement is not effective in increasing bone density in adult women with AN. However, physiologic estrogen replacement as transdermal estradiol with cyclic progesterone does increase bone accrual rates in adolescents with AN to approximate that in normal-weight controls, leading to a maintenance of bone density Z-scores. A recent study has shown that risedronate increases bone density at the spine and hip in adult women with AN. However, bisphosphonates should be used with great caution in women of reproductive age given their long half-life and potential for teratogenicity, and should be considered only in patients with low bone density and clinically significant fractures when non-pharmacological therapies for weight gain are ineffective. Further studies are necessary to determine the best therapeutic strategies for low bone density in AN. PMID:24898127

  8. Binge eating as a meaningful experience in bulimia nervosa and anorexia nervosa: a qualitative analysis.

    Eli, Karin

    2015-12-01

    Clinical studies describe binge eating as a reaction to hunger, negative affect, or the need to dissociate. However, little is known about the meanings that women with bulimia nervosa and anorexia nervosa associate with binge eating. To examine how women with anorexia nervosa and bulimia nervosa interpret their experiences of binge eating. Sixteen women who engaged in binge eating and had been diagnosed with anorexia nervosa, bulimia nervosa, or their subclinical variants were interviewed about their experiences of eating disorder. Interview data were analyzed using phenomenologically-informed thematic analysis. Participants described binge eating as a practice through which the self experiences a sense of release, and existential emptiness is replaced by overwhelming fullness. Meaningful experiences of release and fullness are central to binge eating in bulimia nervosa and anorexia nervosa, and may contribute to the long-term maintenance of this practice.

  9. Effects of Berberis vulgaris fractions on PTZ Induced seizure in male rats

    2017-11-01

    Full Text Available Background and objectives: Berberis vulgaris L (Berberidaceae is a medicinal plant that is distributed in different parts of Iran; it is grown as a wild or cultivated plant. It has different pharmacological activities such as antioxidant, anti-inflammatory, anti-arrhythmic, sedative and anti-malaria effects. In this study, the anti-seizure activity of different fractions of this plant was evaluated. Methods: Seventy two rats were randomly divided in to nine groups (n=8 in each group. (1: negative control group (normal saline 10mL/kg, (2: positive control group (sodium valproate 1 mg/kg, (3, 4, 5: hydroalcoholic extract-treated groups (100, 200, 400 mg/kg, (6, 7: methanol fraction-treated groups (100 and 200 mg/kg and (8, 9: chloroform fraction-treated group (100 and 200 mg/kg. Thirty minute after peritoneal injection of different doses of extract, fractions, saline and gavage of sodium valproate, PTZ (45 mg/kg was injected and they were immediately transferred to a special cage, and the seizure parameters were evaluated for 30 min. Result: The injection of different doses of hydroalcoholic extract and different fractions had a dose-dependent effect on prolongation of latency to the onset of seizures. The effective dose was 400 mg/kg of hydroalcoholic extract and 200 mg/kg of methanol fraction. They decreased the rate of mortality and the number of suddenly seizures jumping significantly. Conclusion: The present study demonstrated that the hydroalcoholic extract and methanol fraction of B. vulgaris showed anticonvulsant activity in PTZ-induced seizures in mice. Therefore, this plant may be more useful in petit mal epilepsy.

  13. Microbial terroir for wine grapes

    Gilbert, J. A.; van der Lelie, D.; Zarraonaindia, I.

    2013-12-05

    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.

    This study for the first time designed to optimize the extraction of phenolic compounds and antioxidant potential of Berberis asiatica fruits using response surface methodology (RSM). Solvent selection was done based on the preliminary experiments and a five-factors-three-level, Central Composite Design (CCD). Extraction temperature (X1), sample to solvent ratio (X3) and solvent concentration (X5) significantly affect response variables. The quadratic model well fitted for all the responses. Under optimal extraction conditions, the dried fruit sample mixed with 80% methanol having 3.0 pH in a ratio of 1:50 and the mixture was heated at 80 °C for 30 min; the measured parameters was found in accordance with the predicted values. High Performance Liquid Chromatography (HPLC) analysis at optimized condition reveals 6 phenolic compounds. The results suggest that optimization of the extraction conditions is critical for accurate quantification of phenolics and antioxidants in Berberis asiatica fruits, which may further be utilized for industrial extraction procedure.

  15. Legitimate seed dispersal by lizards in an alpine habitat: The case of Berberis empetrifolia (Berberidaceae) dispersed by Liolaemus belii (Tropiduridae)

    Celedón-Neghme, Constanza; San Martin, Leonardo A.; Victoriano, Pedro F.; Cavieres, Lohengrin A.

    2008-05-01

    In this study we determined the effect of seed passage through Liolaemus bellii lizard digestive tracts on germination of fleshy-fruited Andean shrub species Berberis empetrifolia (Berberidaceae), and evaluated the effect of this passage on seed coat characteristics. In addition, we assessed the spatial patterns of fecal deposition by lizards onto various microhabitats available in the Andean environments of central Chile. The germination rate and the final percentage of lizard-ingested B. empetrifolia seeds was greater than control seeds. Comparing photographs and seed coat histological cuts, we suggest that the cutine wax present on seed coats from lizard-ingested seeds was probably removed by abrasion inside the lizards' digestive tract. Sixty-two percent of the lizard's feces was deposited on bare soil near rocks commonly inhabited by lizards. However, this microhabitat represents only 29% of the available ground cover at the study site. By enhancing seed germination and depositing seeds onto potential safe sites for recruitment, the lizard Liolaemus bellii is acting, at least qualitatively, as an effective disperser of Berberis empetrifolia.

In addition, malnutrition can cause different problems of central nervous system, whereas reports on periphere nerve lesions are rare. We report a case of a 14 8/12 years old girl suffering from anorexia nervosa since five months, who presented with peroneal nerve palsy. In association to anorexia nervosa the prognosis of this mononeuropathy seems to be good. Anorectic patients with neurological complications need an interdisciplinary medical treatment.

  18. Anorexia nervosa and bulimia nervosa: brains, bones and breeding.

    Starr, Taylor B; Kreipe, Richard E

    2014-05-01

    Recent research has modified both the conceptualization and treatment of eating disorders. New diagnostic criteria reducing the "not otherwise specified" category should facilitate the early recognition and treatment of anorexia nervosa (AN) and bulimia nervosa (BN). Technology-based studies identify AN and BN as "brain circuit" disorders; epidemiologic studies reveal that the narrow racial, ethnic and income profile of individuals no longer holds true for AN. The major organs affected long term-the brain and skeletal system-both respond to improved nutrition, with maintenance of body weight the best predictor of recovery. Twin studies have revealed gene x environment interactions, including both the external (social) and internal (pubertal) environments of boys and of girls. Family-based treatment has the best evidence base for effectiveness for younger patients. Medication plays a limited role in AN, but a major role in BN. Across diagnoses, the most important medicine is food.

    Full text: The riches of flora of Azerbaijan with its specific saturation represent a huge raw-material base for a farmaceutical industry. In territory of republic 3 kinds of a barberry wildly grow, a perspective kind is the barberry ordinary Berberis vulgaris L.In the medical purposes leaves, a root, stalks and fruits of a barberry are applied. Berries as water tincture are applied at rheumatism, a malaria, a diabetes [I.A.Damirov and etn-tilde 1988; Hofbauer F., Askeril M, 2002, etc.], at diseases of a gastroenteric path, easy, at diseases of a mouth [Ikram M, 1975]. Biochemical processes in the collected raw material during first time proceed, as in an alive plant, that is synthesis of biologi-cally active substances prevails. On a measure natural losing water in connection with the termination of receipt of a moisture and nutrients, processes of an exchange are shifted aside disintegration that results in decrease of biologically active substances in vegetative raw material. However in some cases the processes proceeding in drying raw material result on the contrary, in increase in the maintenance of working substances. Therefore improvement of ways of drying and processing of medicinal raw material by influence of small dozes ? - radiations c the purpose of reception of the high-quality raw material, connected with growing need of a global farmaceutical industry for herbs and phitopreparats is an actual problem. As a result of experimental researches conditions of radiating sterilization of fruits of a barberry ?-radiation are picked up at small dozes and at different values ionizating radiations. Fruits of a barberry were irradiated with ?-radiation on radioisotope installation 60n-tildei-circumflex at values of a doze of an irradiation in limits from 1.0 up to 1.5eGr at duration of an irradiation till 30 minutes. The qualitative control were carried out chromatografic (thin layer chromatography) and spectral (UV-VIS and IR) methods later 6, 12 and 24 months

    The cross-sectional study aimed at examining the sexual function of young adult women suffering from eating disorders. The authors interviewed 53 women (26 with anorexia nervosa and 27 with bulimia nervosa) and 58 female students. Each participant was administered the Female Sexual Function Index, the Eating Attitudes Test, the Body Shape Questionnaire, and the Beck Depression Inventory. Comparisons among the 3 groups showed that patients with anorexia nervosa scored lower in each Female Sexual Function Index subscale than did healthy controls. There was no significant difference between bulimia nervosa and healthy controls. Sexual functionality of patients with anorexia nervosa was correlated only with body mass index (r = 0.5, p =.01). Sexual functionality of patients with bulimia nervosa was correlated only with the Beck Depression Inventory (r = -0.4, p =.03) Patients with anorexia nervosa had more disturbed sexual function than did controls. Sexual function can be related to the level of starvation and symptoms of depression.

    Highlights: • Microcalorimetry was applied to monitor grape withering. • Heat flow was used to estimate rate of respiration. • Calorimetry was coupled with analysis of volatile compounds. • Data analysis showed three steps of withering. - Abstract: This work aimed at monitoring the metabolic activity of grapes during withering by microcalorimetry. Samples of Corvina grapes, a cultivar used in the production of Amarone wine, were dehydrated for about 120 days at an industrial scale plants (fruttaia). Single berries, sampled in the course of the withering process, were closed in ampoules and maintained at constant temperature. As biochemical events (i.e. berry respiration, microbial growth, etc.) are always accompanied by the production of heat (q), the heat-flow (dq/dt) emitted by berries enclosed in the ampoules was used to monitor their metabolic activity during withering, i.e. respiration. For each sampling time, the heat rate production of the berries at 298 K was monitored till a steady state signal was achieved (within 60 h). Such heat flow value was used as marker during the entire withering process (120 days). Its trend allowed to characterize the changes in the metabolic activity of the grape berries along the withering process. To understand the origin of such changes, the emission of volatile organic compounds (VOCs) were also measured by proton transfer mass spectrometry (PTR-MS). The use of microcalorimetry associated with the analysis of specific VOCs fragments offered a valuable information to describe the withering process.

    OBJECTIVE Although anorexia nervosa has a high mortality rate, our understanding of the timing and predictors of mortality in eating disorders is limited. The authors investigated mortality in a long-term study of patients with eating disorders. METHOD Beginning in 1987, 246 treatment-seeking female patients with anorexia nervosa or bulimia nervosa were interviewed every 6 months for a median of 9.5 years to obtain weekly ratings of eating disorder symptoms, comorbidity, treatment participation, and psychosocial functioning. From January 2007 to December 2010 (median follow-up of 20 years), vital status was ascertained with a National Death Index search. RESULTS Sixteen deaths (6.5%) were recorded (lifetime anorexia nervosa, N=14; bulimia nervosa with no history of anorexia nervosa, N=2). The standardized mortality ratio was 4.37 (95% CI=2.4-7.3) for lifetime anorexia nervosa and 2.33 (95% CI=0.3-8.4) for bulimia nervosa with no history of anorexia nervosa. Risk of premature death among patients with lifetime anorexia nervosa peaked within the first 10 years of follow-up, resulting in a standardized mortality ratio of 7.7 (95% CI=3.7-14.2). The standardized mortality ratio varied by duration of illness and was 3.2 (95% CI=0.9-8.3) for patients with lifetime anorexia nervosa for 0 to 15 years (4/119 died), and 6.6 (95% CI=3.2-12.1) for those with lifetime anorexia nervosa for >15 to 30 years (10/67 died). Multivariate predictors of mortality included alcohol abuse, low body mass index, and poor social adjustment. CONCLUSIONS These findings highlight the need for early identification and intervention and suggest that a long duration of illness, substance abuse, low weight, and poor psychosocial functioning raise the risk for mortality in anorexia nervosa.

  8. Evaluation of Nutritive Value, Phenolic Compounds and in vitro Digestion Charactristics of Barberry (Berberis Vulgaris Foliage

    Full Text Available Introduction This study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. Berberis vulgaris is one of the major crops in the province. The province has more than 70 percent and 95 percent of the total area under cultivation of barberry. Waste and foliage of barberry harvest traditionally used to feed livestock Tannin concentration greater than 3 to 4 percent in food, can have negative effects on digestibility in ruminants and in particular to reduce the absorption of dietary protein. So it can be expected that high amounts of tannins within waste foliage of barberry reduce its efficiency in ruminants to be fed. Several studies have shown that the addition of certain compounds such as urea, polyethylene Due to the high volume of barberry foliage that remains after harvesting and the possibility of its use in animal nutrition, this study tried to determine some nutrient compounds, phenolic compounds and degradation parameters were barberry leaves. In addition, in this study to determine the best additives are effective in reducing the concentration of tannins and phenolic compounds, urea, polyethylene glycol, sodium hydroxide and calcium hydroxide were compared. Materials and method As the samples were dried by the sun for 6 days. The amount of 5% by weight (dry matter basis urea, polyethylene glycol, sodium hydroxide or calcium hydroxide that was prepared with distilled water, was sprayed on 5 kg of the sample and thoroughly mixed. Each of the treatments were prepared in triplicate. Treatments include: 1 control (foliage without additives, 2 foliage with 5% solution of urea, 3 foliage with 5% polyethylene glycol, 4 foliage with 5% sodium hydroxide, 5 with 5% calcium hydroxide was foliage. The sample were kept in anaerobic plastic containers for 3 days and then opened and dried at room temperature. Samples were analyzed for crude protein, neutral detergent fiber, acid detergent

    Full Text Available La Anorexia Nervosa es un trastorno de alimentación que se define (etimológicamente como una "pérdida nerviosa del apetito". Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos  de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio. Anorexia Nervosa is an Eating Disorder defined (etimoligacally as a "nervouse loss of apetite". It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

  12. Understanding the 'Anorexic Voice' in Anorexia Nervosa.

    Pugh, Matthew; Waller, Glenn

    2017-05-01

    In common with individuals experiencing a number of disorders, people with anorexia nervosa report experiencing an internal 'voice'. The anorexic voice comments on the individual's eating, weight and shape and instructs the individual to restrict or compensate. However, the core characteristics of the anorexic voice are not known. This study aimed to develop a parsimonious model of the voice characteristics that are related to key features of eating disorder pathology and to determine whether patients with anorexia nervosa fall into groups with different voice experiences. The participants were 49 women with full diagnoses of anorexia nervosa. Each completed validated measures of the power and nature of their voice experience and of their responses to the voice. Different voice characteristics were associated with current body mass index, duration of disorder and eating cognitions. Two subgroups emerged, with 'weaker' and 'stronger' voice experiences. Those with stronger voices were characterized by having more negative eating attitudes, more severe compensatory behaviours, a longer duration of illness and a greater likelihood of having the binge-purge subtype of anorexia nervosa. The findings indicate that the anorexic voice is an important element of the psychopathology of anorexia nervosa. Addressing the anorexic voice might be helpful in enhancing outcomes of treatments for anorexia nervosa, but that conclusion might apply only to patients with more severe eating psychopathology. Copyright © 2016 John Wiley & Sons, Ltd. Experiences of an internal 'anorexic voice' are common in anorexia nervosa. Clinicians should consider the role of the voice when formulating eating pathology in anorexia nervosa, including how individuals perceive and relate to that voice. Addressing the voice may be beneficial, particularly in more severe and enduring forms of anorexia nervosa. When working with the voice, clinicians should aim to address both the content of the voice and how

    The course of eating disorders is often protracted, with fewer than half of adults achieving recovery from anorexia nervosa or bulimia nervosa. Some argue for palliative management when duration exceeds a decade, yet outcomes beyond 20 years are rarely described. This study investigates early and long-term recovery in the Massachusetts General Hospital Longitudinal Study of Anorexia and Bulimia Nervosa. Females with DSM-III-R/DSM-IV anorexia nervosa or bulimia nervosa were assessed at 9 and at 20 to 25 years of follow-up (mean [SD] = 22.10 [1.10] years; study initiated in 1987, last follow-up conducted in 2013) via structured clinical interview (Longitudinal Interval Follow-Up Evaluation of Eating Disorders [LIFE-EAT-II]). Seventy-seven percent of the original cohort was re-interviewed, and multiple imputation was used to include all surviving participants from the original cohort (N = 228). Kaplan-Meier curves estimated recovery by 9-year follow-up, and McNemar test examined concordance between recovery at 9-year and 22-year follow-up. At 22-year follow-up, 62.8% of participants with anorexia nervosa and 68.2% of participants with bulimia nervosa recovered, compared to 31.4% of participants with anorexia nervosa and 68.2% of participants with bulimia nervosa by 9-year follow-up. Approximately half of those with anorexia nervosa who had not recovered by 9 years progressed to recovery at 22 years. Early recovery was associated with increased likelihood of long-term recovery in anorexia nervosa (odds ratio [OR] = 10.5; 95% CI, 3.77-29.28; McNemar χ²₁ = 31.39; P bulimia nervosa (OR = 1.0; 95% CI, 0.49-2.05; McNemar χ²₁ = 0; P = 1.0). At 22 years, approximately two-thirds of females with anorexia nervosa and bulimia nervosa were recovered. Recovery from bulimia nervosa happened earlier, but recovery from anorexia nervosa continued over the long term, arguing against the implementation of palliative care for most individuals with eating disorders. © Copyright

  17. Initial evaluation, diagnosis, and treatment of anorexia nervosa and bulimia nervosa.

    Harrington, Brian C; Jimerson, Michelle; Haxton, Christina; Jimerson, David C

    2015-01-01

    Eating disorders are life-threatening conditions that are challenging to address; however, the primary care setting provides an important opportunity for critical medical and psychosocial intervention. The recently published Diagnostic and Statistical Manual of Mental Disorders, 5th ed., includes updated diagnostic criteria for anorexia nervosa (e.g., elimination of amenorrhea as a diagnostic criterion) and for bulimia nervosa (e.g., criterion for frequency of binge episodes decreased to an average of once per week). In addition to the role of environmental triggers and societal expectations of body size and shape, research has suggested that genes and discrete biochemical signals contribute to the development of eating disorders. Anorexia nervosa and bulimia nervosa occur most often in adolescent females and are often accompanied by depression and other comorbid psychiatric disorders. For low-weight patients with anorexia nervosa, virtually all physiologic systems are affected, ranging from hypotension and osteopenia to life-threatening arrhythmias, often requiring emergent assessment and hospitalization for metabolic stabilization. In patients with frequent purging or laxative abuse, the presence of electrolyte abnormalities requires prompt intervention. Family-based treatment is helpful for adolescents with anorexia nervosa, whereas short-term psychotherapy, such as cognitive behavior therapy, is effective for most patients with bulimia nervosa. The use of psychotropic medications is limited for anorexia nervosa, whereas treatment studies have shown a benefit of antidepressant medications for patients with bulimia nervosa. Treatment is most effective when it includes a multidisciplinary, teambased approach.

  18. [Anesthesia in patients with anorexia nervosa and bulimia nervosa].

    2010-03-01

    Eating disorders are typical diseases of adolescence and early adulthood. About 1-3% of female juveniles suffer from anorexia nervosa (AN) or bulimia nervosa (BN). Today AN is still the psychiatric disease with the highest mortality rate. The peri-operative mortality rate of patients suffering from AN is in the range up to 15%. The beginning of AN is a lingering process and the majority of patients show increasingly restrictive eating habits ending in cachexia. Patients are obsessed by the predominant idea of being obese in spite of having a significant underweight. Patients suffering from bulimia break the strict regimen by eating enormous amounts of high calorie food. Such eating attacks are followed by weight reducing measures, mostly vomiting. Most of the physical changes caused by AN are due to starvation and loss of weight. The most significant medical complications are alterations of the cardiovascular system accompanied by decreasing contractility of the heart, bradycardia, electrocardiographic changes as well as disequilibrium of electrolytic and water balance. Most of these symptoms can be reversed by putting on weight.

    The aim of this study is to describe oral lesions in patients with eating disorders (ED), including Anorexia Nervosa (AN), Bulimia Nervosa (BN) and eating disorders not otherwise specified (EDNOS). A prospective case-control study was carried out from April 2003 to May 2004. Inclusion criteria for the study group were individuals with a diagnosis of ED; age and sex-matched individuals without ED were included as controls. Clinical data regarding ED, medical complications and oral examination were performed by previously calibrated professionals. Study group (n = 65) presented 46 cases of BN (71%), 13 of EDNOS (20%) and 6 of AN (9%); also, 94% (n = 61) showed oral lesions. The most common were: labial erythema, exfoliative cheilitis, orange-yellow palate, hemorrhagic lesions, lip-cheek biting and non-specific oral atrophies. Only two patients of the study group had dental erosions, and no case of major salivary gland swelling was found. ED display a wide array of oral mucosal lesions that can be regarded as their early manifestations. The dentist could be the first professional to detect symptoms of eating disorders, potentially improving early detection and treatment of ED. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2015-05-01

    This study explored the neuropsychological performance of patients diagnosed with anorexia nervosa (AN) or bulimia nervosa (BN) compared with healthy controls (HCs). An additional aim was to investigate the effect of several possible mediators on the association between eating disorders (EDs) and cognitive function. Forty patients with AN, 39 patients with BN, and 40 HCs who were comparable in age and education were consecutively recruited to complete a standardized neuropsychological test battery covering the following cognitive domains: verbal learning and memory, visual learning and memory, speed of information processing, visuospatial ability, working memory, executive function, verbal fluency, attention/vigilance, and motor function. The AN group scored significantly below the HCs on eight of the nine measured cognitive domains. The BN group also showed inferior performance on six cognitive domains. After adjusting for possible mediators, the nadir body mass index (lowest lifetime BMI) and depressive symptoms explained all findings in the BN group. Although this adjustment reduced the difference between the AN and HC groups, the AN group still performed worse than the HCs regarding verbal learning and memory, visual learning and memory, visuospatial ability, working memory, and executive functioning. Patients with EDs scored below the HCs on several cognitive function measures, this difference being most pronounced for the AN group. The nadir BMI and depressive symptoms had strong mediating effects. Longitudinal studies are needed to identify the importance of weight restoration and treatment of depressive symptoms in the prevention of a possible cognitive decline. © 2014 Wiley Periodicals, Inc.

    Full Text Available The aim of study was to detect the microscopic filamentous fungi from wine surface of sterilized grapes berries of Slovak origin. We analyzed 21 samples of grapes, harvested in the year 2012 of various wine-growing regions. For the isolation of species we used the method of direct plating surface-sterilized berries (using 0.4% freshly pre-pared chlorine on DRBC (Dichloran Rose Bengal Chloramphenicol agar. The cultivation was carried at 25±1°C, for 5 to 7 days. A total number of 2541 fungal isolates pertaining to 18 genera including Mycelia sterilia were recovered. Isolates of genus Alternaria were found in all of tested samples with the highest relative density 56.4%. The second highest isolation frequency we detected for genus Fusarium (90.48% positive samples, but with low relative density (31 isolates and 2.99% RD. Another genera with higher isolation frequency were Cladosporium (Fr 85.71%, RD 14.6%, Mycelia sterilia (Fr 85.71%, RD 4.25%, Penicillium (Fr 80.95%, RD 13.42%, Botrytis (Fr 71.43%, RD 2.95% Rhizopus (Fr 66.66%, RD 1.34%, Aspergillus (Fr 57.14%, RD 0.87%, Epicoccum (Fr 47.62%, RD 1.22%, Trichoderma (Fr 42.86%, RD 1.26%. Isolation frequency of another eight genera (Arthrinium, Dichotomophtora, Geotrichum, Harzia, Chaetomium, Mucor, Nigrospora and Phoma was less than 10% and relative density less than 0.5%. Chosen isolates of potential producers of mycotoxin (species of Alternaria, Aspergillus, Fusarium and Penicillium were tested for the ability to produce relevant mycotoxins in in vitro conditions using TLC method. None isolate of Aspergillus niger aggregate (13 tested did not produce ochratoxin A – mycotoxin monitored in wine and another products from grapes berries. Isolates of potentially toxigenic species recovered from the samples were found to produce another mycotoxins: aflatoxin B1, altenuene, alternariol, alternariol monomethylether, citrinin, diacetoxyscirpenol, deoxynivalenol, HT-2 patulin, penitrem A and T-2 toxin

    Full Text Available Dietary fibres from cereals are much more used than dietary fibres from fruits; however, dietary fibres from fruits have better quality. In recent years, for economic and environmental reasons, there has been a growing pressure to recover and exploit food wastes. Grape fibre is used to fortify baked goods, because the fibre can lower blood sugar, cut cholesterol and may even prevent colon cancer. Grape pomace is a functional ingredient in bakery goods to increase total phenolic content and dietary fibre in nourishment. The aim of this study was to determine the chemical composition of commercial fibres, obtained from different Grape sources concerning their chemical properties such as moisture, ash, fat, protein, total dietary fibre. The chemical composition of Grape fibre is known to vary depending on the Grape cultivar, growth climates, and processing conditions. The obliged characteristics of the fibre product are: total dietary fibre content above 50%, moisture lower than 9%, low content of lipids, a low energy value and neutral flavour and taste. Grape pomace represents a rich source of various high-value products such as ethanol, tartrates and malates, citric acid, Grape seed oil, hydrocolloids and dietary fibre. Used commercial Grape fibres have as a main characteristic, the high content of total dietary fibre. Amount of total dietary fibre depends on the variety of Grapes. Total dietary fibre content (TDF in our samples of Grape fibre varied from 56.8% to 83.6%. There were also determined low contents of moisture (below 9%. In the samples of Grape fibre were determined higher amount of protein (8.6 - 10.8%, mineral (1.3 - 3.8% and fat (2.8 - 8.6%. This fact opens the possibility of using both initial by-products as ingredients in the food industry, due to the effects associated with the high total dietary fibre content.

  6. Anorexia Nervosa, Obesity and Bone Metabolism

    Misra, Madhusmita; Klibanski, Anne

    2014-01-01

    Anorexia nervosa and obesity are conditions at the extreme ends of the nutritional spectrum, associated with marked reductions versus increases respectively in body fat content. Both conditions are also associated with an increased risk for fractures. In anorexia nervosa, body composition and hormones secreted or regulated by body fat content are important determinants of low bone density, impaired bone structure and reduced bone strength. In addition, anorexia nervosa is characterized by increases in marrow adiposity and decreases in cold activated brown adipose tissue, both of which are related to low bone density. In obese individuals, greater visceral adiposity is associated with greater marrow fat, lower bone density and impaired bone structure. In this review, we discuss bone metabolism in anorexia nervosa and obesity in relation to adipose tissue distribution and hormones secreted or regulated by body fat content. PMID:24079076

  9. The microbial ecology of wine grape berries.

    Barata, A; Malfeito-Ferreira, M; Loureiro, V

    2012-02-15

    Grapes have a complex microbial ecology including filamentous fungi, yeasts and bacteria with different physiological characteristics and effects upon wine production. Some species are only found in grapes, such as parasitic fungi and environmental bacteria, while others have the ability to survive and grow in wines, constituting the wine microbial consortium. This consortium covers yeast species, lactic acid bacteria and acetic acid bacteria. The proportion of these microorganisms depends on the grape ripening stage and on the availability of nutrients. Grape berries are susceptible to fungal parasites until véraison after which the microbiota of truly intact berries is similar to that of plant leaves, which is dominated by basidiomycetous yeasts (e.g. Cryptococcus spp., Rhodotorula spp. Sporobolomyces spp.) and the yeast-like fungus Aureobasidium pullulans. The cuticle of visually intact berries may bear microfissures and softens with ripening, increasing nutrient availability and explaining the possible dominance by the oxidative or weakly fermentative ascomycetous populations (e.g. Candida spp., Hanseniaspora spp., Metschnikowia spp., Pichia spp.) approaching harvest time. When grape skin is clearly damaged, the availability of high sugar concentrations on the berry surface favours the increase of ascomycetes with higher fermentative activity like Pichia spp. and Zygoascus hellenicus, including dangerous wine spoilage yeasts (e.g. Zygosaccharomyces spp., Torulaspora spp.), and of acetic acid bacteria (e.g. Gluconobacter spp., Acetobacter spp.). The sugar fermenting species Saccharomyces cerevisiae is rarely found on unblemished berries, being favoured by grape damage. Lactic acid bacteria are minor partners of grape microbiota and while being the typical agent of malolactic fermentation, Oenococcus oeni has been seldom isolated from grapes in the vineyard. Environmental ubiquitous bacteria of the genus Enterobacter spp., Enterococcus spp., Bacillus spp

    this regard, drought stress tolerance thresholds of ornamental barberry plant in Mashhad landscape were evaluated. Materials and Methods: In order to determine the qualitative and quantitative drought stress tolerance thresholds of ornamental barberry (Berberis thunbergii plant an experiment was conducted basis on randomized complete block design with three replications in Plant Production Complex of Mashhad Municipality. Treatments included; 100, 80, 60, 40, and 20% of culculated water requirements based on evaporation pan data. Two years old plants with similar size were transplanted from pots to field in 16 March 2012. Treatments were applied after establishment in 28 April and sampling was arranged in 6 August, 23 August, 6 September, and 7 October. During the growing season, the evaporation level was daily measured from pan Class A. In each sampling two plants sampled randomly from each plot for measuring the plant height, highest branches, number of branches, fresh and dry weight, dry mater percentage, irrigation water use index and freshness index. Results and Discussion: Results showed that with increasing severity of drought stress plant height of barberry reduced significantly, but there were no significant difference between 100 and 80% of water requirement treatments. The highest branches reduced by diminishing water application volume but there were no significant difference among 100, 80 and 60% of water requirement application. The maximum of branch number was observed at 60 percent water requirement, however, there were no significant difference between 100 and 60% of water requirement treatments. The number of branches in 60% was 26% lower than 80% of water requirement. Therefore, application of 60% water requirement with 23 branches per plant produced highest branch number. The highest and lowest plant fresh weight was measured in 100% and 20% water requirement application, respectively. Application of 60% of water requirement produced statistically

  12. The Enigmatic Persistence of Anorexia Nervosa

    Walsh, B. Timothy

    2014-01-01

    Objective In this review, based on recent advances in cognitive neuroscience, the author presents a formulation in which the marked persistence of anorexia nervosa can be usefully understood as a well-ingrained maladaptive habit. Method The author reviewed the relevant literature on the development and course of anorexia nervosa and interpreted critical features in light of developments in cognitive neuroscience. Results Anorexia nervosa is a well characterized disorder with remarkable persistence both across history and among affected individuals. Food restriction, the salient behavioral feature of the disorder, often begins innocently but gradually takes on a life of its own. Over time, it becomes highly entrenched and resistant to change through either psychological or pharmacological treatment. Cognitive neuroscience has described two related but distinct processes that underlie the acquisition of new patterns of behavior, namely, action-outcome and stimulus-response learning. It is likely that both processes are engaged in the development of anorexia nervosa and that stimulus-response learning (that is, habit formation) is critical to the persistence of the dieting behavior. Conclusions The formulation of the dieting behavior characteristic of anorexia nervosa as a well-entrenched habit provides a basis for understanding the striking persistence of this disorder. This model helps explain the resistance of anorexia nervosa to interventions that have established efficacy in related disorders and implies that addressing the dieting behavior is critical, especially early in the course of the illness, before it has become ingrained.

  13. GLUCOSE-FRUCTOSE INDEX IN THE GRAPES

    N. V. Gnilomedova

    2016-01-01

    Full Text Available Results summarize literature and experimental data on the content of glucose and fructose of different varieties in grapes belonging to different botanical species of Vitis. The ratio of glucose and fructose indicator can be used for fermentation control and prevention of under fermentation in the production of dry wines, as well as an identification parameter to assess the authenticity of grape juice and concentratedmust. The object of the study were grapes of red and white winemaking European and autochthonous varieties, belonging to Vitis, as well as varieties of new selection (Aligote, Albilio, Verdelho, Sersial, Rkatsiteli, White Muscat, Cabernet-Sauvignon, Bastardo of Magarach, Kephesiya, Ekim kara, Golubok. Sugar content in grape samples was inthe range of 180-260 g/l. Total hexoses were determined by HPLC method according to a modified methodology developed by the Department of Chemistry and Biochemistry of Wine of "FSBSI "Magarach ". It was established that the value range of the glucose-fructose index in the grapes cultivated in different viniviticultural regions of the world makes 0.74-1.19. It has been revealed that the glucose-fructose index decreases with the ripening of berries. Low index values are characteristic for the grape that ripens at high temperatures and was cultivated in regions with hot climate. High index valuesare characteristic of table grapes and winemaking grape varieties of the species Vitis labrusca, Vitis amurensis and interspecific hybrids. Within the botanical species we canidentify varieties that tend to accumulate higher volumes of either glucose or fructose. These patterns are equally characteristic of white and red grape varieties. The analytical analyzes of the Crimean winemaking grape varieties resulted in the establishment of the glucose-fructose index for the first time, varying within the range of 0.9-1.06.

    2017-12-01

    Research investigating the link between eating disorder (ED) diagnosis and executive dysfunction has had conflicting results, yet no meta-analyses have examined the overall association of ED pathology with executive functioning (EF). Effect sizes were extracted from 32 studies comparing ED groups (27 of anorexia nervosa, 9 of bulimia nervosa) with controls to determine the grand mean effect on EF. Analyses included effects for individual EF measures, as well as an age-based subgroup analysis. There was a medium effect of ED diagnosis on executive functioning, with bulimia nervosa demonstrating a larger effect (Hedges's g=-0.70) than anorexia nervosa (g=-0.41). Within anorexia nervosa studies, subgroup analyses were conducted for age and diagnostic subtype. The effect of anorexia nervosa on EF was largest in adults; however, subgroup differences for age were not significant. Anorexia and bulimia nervosa are associated with EF deficits, which are particularly notable for individuals with bulimia nervosa. The present analysis includes recommendations for future studies regarding study design and EF measurement. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The diagnostic consideration of the eating disorders anorexia nervosa and bulimia nervosa has been given much focus over the last two decades than previously, as clinicians have become more aware of the frequency of these disorders and the difficulties associated with their treatment. Anorexia nervosa and bulimia nervosa as known in the DSM-IV as eating disorders are characterized by physically and/or psychologically harmful eating patterns. Although the psychological explanation of what we now call anorexia nervosa have been known about for centuries, it has only recently attracted much interest, due to greater public knowledge and increased incidence (according to Gross and MclLveen 2006, the latter claim has been disputed. Most people suffering from anorexia nervosa and bulimia nervosa start by fasting. Anorexia nervosa is a deliberate self-starvation. A person whose body weight is less than expected for his or her body height and weight is considered to be anorexic. In contract, bulimia involves binge eating a large quantity of food followed by purging by self-induced vomiting, enemas, laxatives, or diuretics.

    2015-01-01

    No epidemiologic survey examining eating disorders in Japan has been done at a national level since 1992. The prevalence of anorexia nervosa, as assessed by questionnaires to hospitals, is thought to be underestimated because patients with anorexia nervosa tend to avoid consultations. In conformity with the School Health and Safety Act of Japan, schools are required to have physicians perform a medical examination of students every year. The teachers in charge of health education and school physicians determine the height, weight, and health condition, and examine the medical records of each student. Therefore, we as members of the Survey Committee for Eating Disorders of the Japanese Ministry of Health, Labour, and Welfare conducted an epidemiologic survey using questionnaires sent to schools in seven prefectures to determine the current prevalence of anorexia nervosa among adolescents. We sent a questionnaire to elementary, junior high, and senior high schools. Questionnaires contained items on the number of students, patients with anorexia nervosa in each grade who were diagnosed by specialists, and students who the school physician strongly suspected to have anorexia nervosa but who did not undergo a clinical examination in a medical institution. We found patients of both sexes with anorexia nervosa aged 9-10 years in elementary schools. The point prevalence of anorexia nervosa for girls, including strongly suspected cases, in the three grades of junior high school and three grades of senior high school were 0-0.17 %, 0-0.21 %, 0.17-0.40 %, 0.05-0.56 %, 0.17-0.42 % and 0.09-0.43 %, respectively. We also confirmed a prominent sex difference in the prevalence of anorexia nervosa. The prevalence of boys was one third that of girls in some prefectures. One third to one half of diagnosed and strongly suspected students with anorexia nervosa had not received medical consultation or treatment. Although the prevalence of anorexia nervosa had regional differences

  2. Bone Metabolism in Anorexia Nervosa

    Fazeli, Pouneh K.; Klibanski, Anne

    2014-01-01

    Anorexia nervosa (AN), a psychiatric disorder predominantly affecting young women, is characterized by self-imposed chronic nutritional deprivation and distorted body image. AN is associated with a number of medical co-morbidities including low bone mass. The low bone mass in AN is due to an uncoupling of bone formation and bone resorption, which is the result of hormonal adaptations aimed at decreasing energy expenditure during periods of low energy intake. Importantly, the low bone mass in AN is associated with a significant risk of fractures and therefore treatments to prevent bone loss are critical. In this review, we discuss the hormonal determinants of low bone mass in AN and treatments that have been investigated in this population. PMID:24419863

    2016-01-01

    Anorexia nervosa (AN) is classically defined as a condition in which an abnormally low body weight is associated with an intense fear of gaining weight and distorted cognitions regarding weight, shape, and drive for thinness. This article reviews recent evidences from physiology, genetics, epigenetics, and brain imaging which allow to consider AN as an abnormality of reward pathways or an attempt to preserve mental homeostasis. Special emphasis is put on ghrelino-resistance and the importance of orexigenic peptides of the lateral hypothalamus, the gut microbiota and a dysimmune disorder of neuropeptide signaling. Physiological processes, secondary to underlying, and premorbid vulnerability factors—the “pondero-nutritional-feeding basements”- are also discussed. PMID:27445651

  4. Endocrine Consequences of Anorexia Nervosa

    Misra, Madhusmita; Klibanski, Anne

    2014-01-01

    Summary Anorexia nervosa (AN) is prevalent in adolescents and young adults, and endocrine changes include hypothalamic amenorrhea, a nutritionally acquired growth hormone resistance with low insulin like growth factor-1 (IGF-1), relative hypercortisolemia, decreases in leptin, insulin, amylin and incretins, and increases in ghrelin, PYY and adiponectin. These changes in turn have deleterious effects on bone, and may affect neurocognition, anxiety, depression and eating disorder psychopathology. Low bone density is particularly concerning; clinical fractures occur and changes in both bone microarchitecture and strength estimates have been reported. Recovery causes improvement of many, but not all, hormonal changes, and deficits in bone accrual may persist despite recovery. Physiologic, primarily transdermal, estrogen replacement increases bone density in adolescents, although catch-up is incomplete. In adults, oral estrogen co-administered with rhIGF-1 in one study, and bisphosphonates in another increased bone density, though not to normal. More studies are necessary to determine the optimal therapeutic approach in AN. PMID:24731664

    2018-06-20

    Anorexia nervosa is often accompanied by comorbid mood disorders, in particular depression, but individual or family history of bipolar disorders has not frequently been explored in anorexia nervosa. The objectives of the present study were: (1) to assess the frequency of bipolar disorders in patients with anorexia nervosa hospitalized in adolescence and in their parents, (2) to determine whether the patients with a personal or family history of bipolar disorders present particular characteristics in the way in which anorexia nervosa manifests itself, in their medical history, in the secondary diagnoses established, and in the treatments prescribed. Overall, 97 female patients aged 13 to 20 hospitalized for anorexia nervosa and their parents were assessed. The diagnoses of anorexia nervosa and bipolar disorders were established on the basis of DSM-IV-TR criteria. A high frequency of type II and type V bipolar disorders was observed. The patients with anorexia nervosa and presenting personal or family histories of bipolar disorder had an earlier onset of anorexia nervosa, more numerous hospitalizations, a longer time-lapse between anorexia nervosa onset and hospitalization, more suicide attempts and more psychiatric comorbidities. The occurrence of anorexia nervosa-bipolar disorders comorbidity appears to be considerable and linked to the severity of anorexia nervosa, raising the issue of the relationship between anorexia nervosa and bipolar disorders.

  7. Herbicide residues in grapes and wine.

    Ying, G G; Williams, B

    1999-05-01

    The persistence of several common herbicides from grapes to wine has been studied. Shiraz, Tarrango and Doradillo grapes were separately sprayed with either norflurazon, oxyfluorfen, oxadiazon or trifluralin-persistent herbicides commonly used for weed control in vineyards. The dissipation of the herbicides from the grapes was followed for 28 days following treatment. Results showed that norflurazon was the most persist herbicide although there were detectable residues of all the herbicides on both red and white grapes at the end of the study period. The penetration of herbicides into the flesh of the grapes was found to be significantly greater for white grapes than for red grapes. Small-lot winemaking experiments showed that norflurazon persisted at levels close to the initial concentration through vinification and into the finished wine. The other herbicides degraded, essentially via first-order kinetics, within the period of "first fermentation" and had largely disappeared after 28 days. The use of charcoal together with filter pads, or with diatomaceous earth was shown to be very effective in removing herbicide residues from the wine. A 5% charcoal filter removed more than 96% of the norflurazon persisting in the treated wine.

  8. Potential Anticancer Properties of Grape Antioxidants

    Kequan Zhou

    2012-01-01

    Full Text Available Dietary intake of foods rich in antioxidant properties is suggested to be cancer protective. Foods rich in antioxidant properties include grape (Vitis vinifera, one of the world’s largest fruit crops and most commonly consumed fruits in the world. The composition and cancer-protective effects of major phenolic antioxidants in grape skin and seed extracts are discussed in this review. Grape skin and seed extracts exert strong free radical scavenging and chelating activities and inhibit lipid oxidation in various food and cell models in vitro. The use of grape antioxidants are promising against a broad range of cancer cells by targeting epidermal growth factor receptor (EGFR and its downstream pathways, inhibiting over-expression of COX-2 and prostaglandin E2 receptors, or modifying estrogen receptor pathways, resulting in cell cycle arrest and apoptosis. Interestingly, some of these activities were also demonstrated in animal models. However, in vivo studies have demonstrated inconsistent antioxidant efficacy. Nonetheless, a growing body of evidence from human clinical trials has demonstrated that consumption of grape, wine and grape juice exerts many health-promoting and possible anti-cancer effects. Thus, grape skin and seed extracts have great potential in cancer prevention and further investigation into this exciting field is warranted.

    2014-01-01

    Full Text Available Berberis aetnensis C. Presl (Berberidaceae is a bushy-spiny shrub common on Mount Etna (Sicily. We demonstrated that the alkaloid extract of roots of B. aetnensis C. Presl contains prevalently berberine and berbamine, possesses antimicrobial properties, and was able to counteract the upregulation evoked by glutamate of tissue transglutaminase in primary rat astroglial cell cultures. Until now, there are no reports regarding antioxidant properties of B. aetnensis C. Presl collected in Sicily. Air-dried, powdered roots of B. aetnensis C. Presl were extracted, identified, and quantified by HPLC. We assessed in cellular free system its effect on superoxide anion, radicals scavenging activity of antioxidants against free radicals like the 1,1-diphenyl-2-picrylhydrazyl radical, and the inhibition of xanthine oxidase activity. In primary rat astroglial cell cultures, exposed to glutamate, we evaluated the effect of the extract on glutathione levels and on intracellular production of reactive oxygen species generated by glutamate. The alkaloid extract of B. aetnensis C. Presl inhibited superoxide anion, restored to control values, the decrease of GSH levels, and the production of reactive oxygen species. Potent antioxidant activities of the alkaloid extract of roots of B. aetnensis C. Presl may be one of the mechanisms by which the extract is effective against health disorders associated to oxidative stress.

Advanced glycation end-products (AGE's) formation due to non-enzymatic glycation and oxidative stress has been demonstrated in the pathogenesis of diabetic complications and aging processes. In this study we investigated the antiglycation and antioxidation potential of methanolic extracts of Berberis lyceum and Terminalia chebula. Results indicated that the methanolic extract of B. lyceum had more antiglycation ability with a Minimum inhibitory concentration (MIC50) of 123 meu g/mL as compared to the MIC50 of 110 meu g/ml of T. chebula. While the results of antioxidation assay showed that T. chebula has more antioxidation potential than B. lyceum. T. chebula had 46.55, 35.01 and 32.81% antioxidation potential at 0.5 mg, 0.25 mg and 0.125 mg respectively as compared to the 16.53, 16.09 and 15.10 % oxidation inhibition at same mass values by B. lycium.

    Leishmaniasis has been identified as a major public health problem in tropical and sub-tropical countries. The present study was aimed to investigate antileishmanial effects of various extracts of Berberis vulgaris also its active compoenent, berberine against Leishmania tropica and L. infantum species on in vitro experiments. In this study in vitro antileishmanial activity of various extracts of B. vulgaris also its active compoenent, berberine against promastigote and amastigote stages of L. tropica and L. infantum was evaluated, using MTT assay and in a macrophage model, respectively. Furthermore, infectivity rate and cytotoxicity effects of B. vulgaris and berberine in murine macrophage cells were investigated. The findings of optical density (OD) and IC50 indicated that B. vulgaris particulary berberine significantly (P<0.05) inhibited the growth rate of promastigote stage of L.tropica and L.infantum in comparison to meglumine antimoniate (MA). In addition, B. vulgaris and berberine significantly (P<0.05) decreased the mean number of amastigotes in each macrophage as compared with positive control. In the evaluation of cytotoxicity effects, it could be observed that berberine as compared with B. vulgaris exhibited more cytotoxicity against murine macrophages. Results also showed that when parasites were pre-incubated with B. vulgaris their ability to infect murine macrophages was significantly decreased. B.vulgaris particularly berberine exhibited potent in vitro leishmanicidal effects against L. tropica and L.infantum. Further works are required to evaluate the antileishmanial effects of B.vulgaris on Leishmania species using clinical settings.

    Berberis aetnensis C. Presl (Berberidaceae) is a bushy-spiny shrub common on Mount Etna (Sicily). We demonstrated that the alkaloid extract of roots of B. aetnensis C. Presl contains prevalently berberine and berbamine, possesses antimicrobial properties, and was able to counteract the upregulation evoked by glutamate of tissue transglutaminase in primary rat astroglial cell cultures. Until now, there are no reports regarding antioxidant properties of B. aetnensis C. Presl collected in Sicily. Air-dried, powdered roots of B. aetnensis C. Presl were extracted, identified, and quantified by HPLC. We assessed in cellular free system its effect on superoxide anion, radicals scavenging activity of antioxidants against free radicals like the 1,1-diphenyl-2-picrylhydrazyl radical, and the inhibition of xanthine oxidase activity. In primary rat astroglial cell cultures, exposed to glutamate, we evaluated the effect of the extract on glutathione levels and on intracellular production of reactive oxygen species generated by glutamate. The alkaloid extract of B. aetnensis C. Presl inhibited superoxide anion, restored to control values, the decrease of GSH levels, and the production of reactive oxygen species. Potent antioxidant activities of the alkaloid extract of roots of B. aetnensis C. Presl may be one of the mechanisms by which the extract is effective against health disorders associated to oxidative stress.

    Full Text Available Diabetes mellitus is a complex endocrine disorder. There is a serious attempt to identify antidiabetic compounds from natural sources to use with other drugs for reduction of diabetes complications. Present study is based on the investigation of antihyperglycemic effect of anthocyanin fraction of Berberis integerrima Bunge (AFBI fruits on some physiological parameters (glucose level, glycogen content, and body weight in normal and streptozotocin-induced (STZ-induced diabetic rats and evaluation of synergic effect of this fraction with metformin and glibenclamide. Male Sprague dawley rats were divided into nine groups: healthy control group, diabetic control group, diabetic groups treated with anthocyanin fraction (200, 400 and 1000 mg/kg, respectively; diabetic groups treated with glibenclamide and metformin separately, diabetic groups treated with glibenclamide + anthocyanin fraction (1000 mg/kg, metformin + anthocyanin fraction (1000 mg/kg. Treatment of diabetic rats with AFBI (400, 1000mg/kg significantly decreased blood glucose as compared with control. Moreover, AFBI (400, 1000mg/kg significantly increased liver glycogen and body weight compared to control. Nevertheless, there were no synergistic effects between anthocyanin fraction and metformin or glibenclamide on blood glucose, liver glycogen, and body weight. The results of this study indicate that AFBI possesses hypoglycemic effects and may be considered for evaluation in future diabetes clinical studies.

  14. Phosphoenolpyruvate carboxykinase and gluconeogenesis in grape pericarp.

    Walker, Robert P; Battistelli, Alberto; Moscatello, Stefano; Técsi, László; Leegood, Richard C; Famiani, Franco

    2015-12-01

    Glycolysis from sugars is necessary at all stages of development of grape pericarp, and this raises the question as to why gluconeogenesis from malate occurs. Phosphoenolpyruvate carboxykinase (PEPCK) is required for gluconeogenesis in grape pericarp. In this study we determined the abundance of PEPCK protein and activity in different parts of grape pericarp during its development. Both PEPCK protein and activity were present throughout development, however, in both the skin and the flesh their abundance increased greatly at the start of ripening. This coincided with the onset of the decrease in the malate content of the berry. The location of PEPCK in the pericarp at different stages of development was determined using both immunohistochemistry and dissection. We provide a possible explanation for the occurrence of gluconeogenesis in grape pericarp. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Abstract Sensory analysis is considered one of the main techniques when you want to know the organoleptic qualities of foods. Marketing strategies, showing that some foods produced organically is more nutritious, flavorful than conventional ones are affecting some consumers. The advantages of using radiation in sensory analysis are not the formation of waste, the less nutritional loss and little change in taste of food. The possibility that the fruit is harvested at more advanced maturity, when all characteristics of flavor and external appearance are fully developed is another advantage. The possibility of fruits being packed irradiated prevents contamination after processing. This type of study, ionizing radiation associated with sensory evaluation scarce, making it necessary for future discoveries. The objective this paper was to evaluate the quality of grapes Benitaka after the irradiation process with doses 0,5; 1; 1,5 e 2 kGy. (author)

    We have developed a special-purpose computer for gravitational many-body simulations, GRAPE-5. GRAPE-5 is the successor of GRAPE-3. Both consist of eight custom pipeline chips (G5 chip and GRAPE chip). The difference between GRAPE-5 and GRAPE-3 are: (1) The G5 chip contains two pipelines operating at 80 MHz, while the GRAPE chip had one at 20 MHz. Thus, the calculation speed of the G5 chip and that of GRAPE-5 board are 8 times faster than that of GRAPE chip and GRAPE-3 board. (2) The GRAPE-5 ...

    Dietary fibres from cereals are much more used than dietary fibres from fruits; however, dietary fibres from fruits have better quality. In recent years, for economic and environmental reasons, there has been a growing pressure to recover and exploit food wastes. Grape fibre is used to fortify baked goods, because the fibre can lower blood sugar, cut cholesterol and may even prevent colon cancer. Grape pomace is a functional ingredient in bakery goods to increase total phenolic content and di...

  20. Clinical spectrum of anorexia nervosa in children.

    Atkins, D M; Silber, T J

    1993-08-01

    A retrospective review of 21 patients ages 12 years and younger (age of onset range 7 to 12 years) with anorexia nervosa showed diagnostic delay in the youngest ones, high incidence of family psychiatric history, a remarkable severity of illness, and positive response to intensive treatment. Additional findings included significant comorbidity, a distinct subgroup with personality disorder and another with features of the "vulnerable child syndrome." This broad clinical spectrum of anorexia nervosa in children may explain the great variability in outcome. The development of anorexia nervosa in children relates to a complex combination of etiological and trigger factors. Precipitants identified in this study were physical maturation, entry into junior high, loss, or some combination thereof.

    1997-10-01

    Studies were carried out at the Food Technology Research Department of Myanma Scientific and Technological Research Department to prepare ready to serve grape juice from ripe fruits of the red varieties of grapes. The sugar content of grapes varied from (10) to (14) % depending on the season. To get a maximum content of (16) % sugar in the juice, (2) to (6) % sugar was added. The yields of the seasonal grape juice varied from (62.5) to (72.2) % by weight. The tannin content was (0.36) % by volume in the fresh juice. It was decreased to (0.03) % by volume after the cold storage at (10)C for (10 to 15) days. The pH of the original fruit juice was (3.2). The best juice was obtain when the pH of the juice was(4.0). To obtain the higher yield of the juice, desirable bright colour and rapid clarification, (0.01) %. Pectinex enzyme was added. In this investigation grape juice was preserved with (0.1) % sodium benzoate. Storage studies, which also included microbiological aspects indicated that the pasteurized grape juice bottle can be stored at room temperature for minimum (6) months without any deterioration in quality

  3. Hepatic Complications of Anorexia Nervosa.

    Rosen, Elissa; Bakshi, Neeru; Watters, Ashlie; Rosen, Hugo R; Mehler, Philip S

    2017-11-01

    Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography. Individuals with AN and starvation-induced hepatitis are at increased risk of hypoglycemia due to depleted glycogen stores and impaired gluconeogenesis. Gastroenterology and hepatology consultations are often requested when patients with AN and signs of hepatitis are hospitalized. It should be noted that additional laboratory testing, imaging, or liver biopsy all have low diagnostic yield, are costly, and potentially invasive, therefore, not generally recommended for diagnostic purposes. While the hepatitis of AN can reach severe levels, a supervised increase in caloric intake and a return to a healthy body weight often quickly lead to normalization of elevated aminotransferases caused by starvation.

  4. Subtyping adolescents with bulimia nervosa.

    Chen, Eunice Y; Le Grange, Daniel

    2007-12-01

    Cluster analyses of eating disorder patients have yielded a "dietary-depressive" subtype, typified by greater negative affect, and a "dietary" subtype, typified by dietary restraint. This study aimed to replicate these findings in an adolescent sample with bulimia nervosa (BN) from a randomized controlled trial and to examine the validity and reliability of this methodology. In the sample of BN adolescents (N=80), cluster analysis revealed a "dietary-depressive" subtype (37.5%) and a "dietary" subtype (62.5%) using the Beck Depression Inventory, Rosenberg Self-Esteem Scale and Eating Disorder Examination Restraint subscale. The "dietary-depressive" subtype compared to the "dietary" subtype was significantly more likely to: (1) report co-occurring disorders, (2) greater eating and weight concerns, and (3) less vomiting abstinence at post-treatment (all p'sreliability of the subtyping scheme, a larger sample of adolescents with mixed eating and weight disorders in an outpatient eating disorder clinic (N=149) was subtyped, yielding similar subtypes. These results support the validity and reliability of the subtyping strategy in two adolescent samples.

  5. Social attribution in anorexia nervosa.

    2018-05-01

    People with anorexia nervosa (AN) report socioemotional difficulties; however, measurement has been criticised for lacking ecological validity and the state or trait nature of difficulties remains unclear. Participants (n = 122) were recruited across 3 groups: people who are currently ill with AN (n = 40); people who recovered (RecAN, n = 18); healthy-control participants (n = 64). Participants completed clinical questionnaires and the Social Attribution Task. The Social Attribution Task involves describing an animation of moving shapes, scored for number of propositions offered, accuracy, and social relevance. Groups were compared cross-sectionally. Those with current AN were assessed prepsychological and postpsychological treatments. People with AN provided fewer propositions than other groups and fewer salient social attributions than healthy-control participants. Those who recovered scored intermediately and not significantly different from either group. Following treatment, people with AN demonstrated (nonsignificant) improvements, and no significance between group differences were observed. Findings suggest difficulties for people with AN in providing spontaneous social narrative and in identifying social salience.

  7. Psychopharmacotherapy of anorexia nervosa, bulimia nervosa and binge-eating disorder

    Kruger, S; Kennedy, SH

    2000-01-01

    Pharmacotherapy for anorexia nervosa is considered to be of limited efficacy. However, many studies suffer methodological limitations, and the utility of newer drugs in the treatment of anorexia has not been examined yet. Although there have been more fruitful investigations on the efficacy of medication in the management of bulimia nervosa, there are still many unresolved issues regarding the optimal management of partial remission during the acute treatment phase and the intensity and duration of pharmacotherapy to achieve optimal prophylaxis. Selective serotonin reuptake inhibitors (SSRIs) control the binge urges in binge-eating disorder, but more trials are required to investigate the utility of SSRIs and other agents in maintenance treatment. We review the current status of psychopharmacotherapy for anorexia nervosa, bulimia nervosa and binge-eating disorder and evaluate the merits of newer agents in the treatment of these disorders.

  8. Measurement of nonclinical personality characteristics of women with anorexia nervosa or bulimia nervosa.

    Pryor, T; Wiederman, M W

    1996-10-01

    Past research on personality and eating disorders has most often emphasized personality psychopathology and personality disorders. We further investigated nonclinical personality characteristics among women with anorexia nervosa (n = 35) or bulimia nervosa (n = 45) using the Multidimensional Personality Questionnaire (MPQ; Tellegen, 1982, 1985). The MPQ measures several personality traits that have been shown to consist of a substantial genetic component (Tellegen et al., 1988). In logistic regression analyses, women with anorexia nervosa evidenced greater degrees of control (vs. impulsivity) and general constraint, and a lower degree of absorption in sensory experiences relative to those with bulimia nervosa. Relative to the normative population (Tellegen, 1982), our sample evidenced very low scores on Well-being, Social Closeness, and Positive Affectivity and high scores on Stress Reaction, Alienation, and Negative Affectivity. Our results emphasize the importance of considering nonclinical personality features and temperament, and varying methods of assessment, in the understanding of predisposing factors for eating disorders.

    2016-01-01

    The effectiveness of an individualized outpatient program was investigated in the treatment of bulimia nervosa (BN) and anorexia nervosa (AN). Participants included 151 females who received outpatient eating disorder treatment in the partial hospitalization program, the intensive outpatient program, or a combination of the two programs. Outcome measures included the Eating Disorder Inventory (EDI-2), Beck Depression Inventory (BDI-II), frequency of binge eating and purging, and mean body weight. Findings included significant increases in weight for the AN group, reductions in binge eating frequency for the BN group, and reductions in EDI-2 and BDI-II scores and purging frequency for both groups. This study provides preliminary support for the efficacy of a multimodal program for the treatment of both anorexia nervosa and bulimia nervosa.

  11. Anti-inflammatory and anti-granuloma activity of Berberis aristata DC. in experimental models of inflammation

    Kumar, Rohit; Gupta, Yogendra Kumar; Singh, Surender

    2016-01-01

    Objective: Berberis aristata (Berberidaceae) is an important medicinal plant used in traditional system of medicine for the treatment of rheumatoid arthritis and other inflammatory disorders. The aim of the present study is to scientifically validate the traditional use of BA in the treatment of inflammatory disorders. Materials and Methods: Anti-inflammatory and anti-granuloma activity of BA hydroalcoholic extract (BAHE) were evaluated in experimental models, viz., carrageenan-induced paw edema, cotton pellet-induced granuloma formation, and complete Freund's adjuvant-induced stimulation of peritoneal macrophages in rats. Expression of inflammatory mediators, viz., tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), IL-6, IL-10, TNF-R1, and cyclooxygenase-2 (COX-2) was carried out in serum and peritoneal macrophages to derive the plausible mechanism of BAHE in activated peritoneal macrophages. Results: Pretreatment with BAHE produced a dose-dependent reduction (P < 0.01) in carrageenan-induced paw edema and cotton pellet-induced granuloma model. BAHE treatment produced significant (P < 0.01) reduction in serum inflammatory cytokine levels as compared to control. Protein expression of pro-inflammatory markers, IL-1β, IL-6, TNF-R1, and COX-2, was found to be reduced in stimulated macrophages whereas anti-inflammatory cytokine, IL-10, was upregulated in peritoneal macrophages. Conclusion: The result of the present study thus demonstrates the anti-inflammatory and anti-granuloma activity of BAHE which may be attributed to its inhibitory activity on macrophage-derived cytokine and mediators.

    Full Text Available Objective: One control method of pathogenic microorganisms is using synthetic chemical preservatives and antibiotics. Because of being generally recognized as safe, antibacterial compounds with organic origin are considered important for health. This study was done in order to investigate the antibacterial effects of methanol extracts of the Berberis vulgaris (Barberry, Actinidia deliciosa (Kiwi and Allium cepa L. (Onions on the standard strain (ATCC:19114 of Listeria monocytogenes (L. monocytogenes, as it seems that it is possible to find some important organic and health safe anti-Listerial compounds. Materials and Methods: After collecting the mentioned plants phytology study was done. Then methanol extracts of named plants were prepared and antibacterial effects of these plants against the mentioned strain of L. monocytogenes by the Disk Diffusion, minimum inhibitory concentration (MIC and minimal bactericidal concentration (MBC methods were performed. Also Ampicillin (10 μg/disc was used as the reference antibacterial substance. In order to find the relationship between antibacterial properties of plants extracts independent t test, chi-square and analysis of variance (ANOVA tests were used. Results: Results showed that the extracts of all the three studied plants had antibacterial effects on L. monocytogenes. Average diagonal of growing area in disk diffusion test for barberry, kiwi and onions in order was 12, 15.5 and 11 mm. Also MIC of mentioned plants extracts in order was 125, 62.5, and 125 μg/ml and MBC of named plants was 500, 250 and 500 μg/ ml, respectively. Conclusion: The results of this work showed that methanol extracts of kiwi had stronger anti-Listerial effect than barberry’s and onion’s extracts.

  17. Taste Reward Circuitry Related Brain Structures Characterize Ill and Recovered Anorexia Nervosa and Bulimia Nervosa

    Frank, Guido K.; Shott, Megan E.; Hagman, Jennifer O.; Mittal, Vijay A.

    2013-01-01

    Objective The pathophysiology of the eating disorder anorexia nervosa remains obscure, but structural brain alterations could be functionally important biomarkers. Here we assessed taste pleasantness and reward sensitivity in relation to brain structure, which might be related to food avoidance commonly seen in eating disorders. Method We used structural magnetic resonance brain imaging to study gray and white matter volumes in individuals with restricting type currently ill (n = 19) or recovered-anorexia nervosa (n = 24), bulimia nervosa (n= 19) and healthy control women (n=24). Results All eating disorder groups showed increased gray matter volume of the medial orbitofrontal cortex (gyrus rectus). Manually tracing confirmed larger gyrus rectus volume, and predicted taste pleasantness across all groups. The analyses also indicated other morphological differences between diagnostic categories: Ill and recovered-anorexia nervosa had increased right, while bulimia nervosa had increased left antero-ventral insula gray matter volumes compared to controls. Furthermore, dorsal striatum volumes were reduced in recovered-anorexia and bulimia nervosa, and predicted sensitivity to reward in the eating disorder groups. The eating disorder groups also showed reduced white matter in right temporal and parietal areas when compared to healthy controls. Notably, the results held when controlling for a range of covariates (e.g., age, depression, anxiety, medications). Conclusion Brain structure in medial orbitofrontal cortex, insula and striatum is altered in eating disorders and suggests altered brain circuitry that has been associated with taste pleasantness and reward value.

  18. Increased mortality in bulimia nervosa and other eating disorders.

    Crow, Scott J; Peterson, Carol B; Swanson, Sonja A; Raymond, Nancy C; Specker, Sheila; Eckert, Elke D; Mitchell, James E

    2009-12-01

    Anorexia nervosa has been consistently associated with increased mortality, but whether this is true for other types of eating disorders is unclear. The goal of this study was to determine whether anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified are associated with increased all-cause mortality or suicide mortality. Using computerized record linkage to the National Death Index, the authors conducted a longitudinal assessment of mortality over 8 to 25 years in 1,885 individuals with anorexia nervosa (N=177), bulimia nervosa (N=906), or eating disorder not otherwise specified (N=802) who presented for treatment at a specialized eating disorders clinic in an academic medical center. Crude mortality rates were 4.0% for anorexia nervosa, 3.9% for bulimia nervosa, and 5.2% for eating disorder not otherwise specified. All-cause standardized mortality ratios were significantly elevated for bulimia nervosa and eating disorder not otherwise specified; suicide standardized mortality ratios were elevated for bulimia nervosa and eating disorder not otherwise specified. Individuals with eating disorder not otherwise specified, which is sometimes viewed as a "less severe" eating disorder, had elevated mortality risks, similar to those found in anorexia nervosa. This study also demonstrated an increased risk of suicide across eating disorder diagnoses.

  2. Self-injurious behavior in anorexia nervosa.

    Favaro, A; Santonastaso, P

    2000-08-01

    Recent reports have postulated the existence of two different types of self-injurious behavior: impulsive and compulsive. The aim of the present study is to analyze the dimensionality of self-injurious behavior and to study the link between self-injurious behavior and clinical features in anorexia nervosa. The study involved 236 consecutive patients with anorexia nervosa, diagnosed by DSM-IV criteria. Subjects were evaluated by means of a semistructured interview and self-reported questionnaires, such as the Eating Disorders Inventory and Hopkins Symptom Checklist. A principal component analysis was used to study the dimensionality of different types of self-injurious behavior, including purging. Our findings confirm the distinction between impulsive and compulsive self-injurious behavior. The dimensions appear to be represented as a continuum in both the anorexia nervosa diagnostic subgroups. A third distinct dimension emerged that included self-induced vomiting and laxative/diuretics abuse. Childhood sexual abuse and anxiety significantly predict the presence of impulsive self-injury, whereas obsessionality and age predict compulsive self-injury. The coexistence of a positive score on both dimensions of self-injurious behavior was the strongest predictor of treatment dropout. The present study highlights the importance of self-injurious behavior; it should be given due consideration in future outcome studies on anorexia nervosa

    2013-01-01

    Full Text Available Abstract Background In spite of the role of some psychosomatic factors as alexithymia, mood intolerance, and somatization in both pathogenesis and maintenance of anorexia nervosa (AN, few studies have investigated the prevalence of psychosomatic syndromes in AN. The aim of this study was to use the Diagnostic Criteria for Psychosomatic Research (DCPR to assess psychosomatic syndromes in AN and to evaluate if psychosomatic syndromes could identify subgroups of AN patients. Methods 108 AN inpatients (76 AN restricting subtype, AN-R, and 32 AN binge-purging subtype, AN-BP were consecutively recruited and psychosomatic syndromes were diagnosed with the Structured Interview for DCPR. Participants were asked to complete psychometric tests: Body Shape Questionnaire, Beck Depression Inventory, Eating Disorder Inventory–2, and Temperament and Character Inventory. Data were submitted to cluster analysis. Results Illness denial (63% and alexithymia (54.6% resulted to be the most common syndromes in our sample. Cluster analysis identified three groups: moderate psychosomatic group (49%, somatization group (26%, and severe psychosomatic group (25%. The first group was mainly represented by AN-R patients reporting often only illness denial and alexithymia as DCPR syndromes. The second group showed more severe eating and depressive symptomatology and frequently DCPR syndromes of the somatization cluster. Thanatophobia DCPR syndrome was also represented in this group. The third group reported longer duration of illness and DCPR syndromes were highly represented; in particular, all patients were found to show the alexithymia DCPR syndrome. Conclusions These results highlight the need of a deep assessment of psychosomatic syndromes in AN. Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments.

  11. The GRAPE aerosol retrieval algorithm

    G. E. Thomas

    2009-11-01

    Full Text Available The aerosol component of the Oxford-Rutherford Aerosol and Cloud (ORAC combined cloud and aerosol retrieval scheme is described and the theoretical performance of the algorithm is analysed. ORAC is an optimal estimation retrieval scheme for deriving cloud and aerosol properties from measurements made by imaging satellite radiometers and, when applied to cloud free radiances, provides estimates of aerosol optical depth at a wavelength of 550 nm, aerosol effective radius and surface reflectance at 550 nm. The aerosol retrieval component of ORAC has several incarnations – this paper addresses the version which operates in conjunction with the cloud retrieval component of ORAC (described by Watts et al., 1998, as applied in producing the Global Retrieval of ATSR Cloud Parameters and Evaluation (GRAPE data-set.

    The algorithm is described in detail and its performance examined. This includes a discussion of errors resulting from the formulation of the forward model, sensitivity of the retrieval to the measurements and a priori constraints, and errors resulting from assumptions made about the atmospheric/surface state.

    2014-01-01

    Objective Although anorexia nervosa has a high mortality rate, our understanding of the timing and predictors of mortality in eating disorders is limited. The authors investigated mortality in a long-term study of patients with eating disorders. Method Beginning in 1987, 246 treatment-seeking women with anorexia nervosa or bulimia nervosa were interviewed every 6 months for a median of 9.5 years to obtain weekly ratings of eating disorder symptoms, comorbidity, treatment participation, and psychosocial functioning. From January 2007 to December 2010 (median follow-up of 20 years), vital status was ascertained with a National Death Index search. Results Sixteen deaths (6.5%) were recorded (lifetime anorexia nervosa, N=14; bulimia nervosa with no history of anorexia nervosa, N=2). The standardized mortality ratio was 4.37 [95% CI=2.4-7.3] for lifetime anorexia nervosa and 2.33 [95% CI=0.3-8.4] for bulimia nervosa with no history of anorexia nervosa. Risk of premature death among women with lifetime anorexia nervosa peaked within the first 10 years of follow-up resulting in a standardized mortality ratio of 7.7 [95% CI=3.7-14.2]. The standardized mortality ratio varied by duration of illness and was 3.2 [95% CI=0.9-8.3] for women with lifetime anorexia nervosa for 0-15 years (4/119 died), and 6.6 [95% CI=3.2-12.1] for women with lifetime anorexia nervosa for >15-30 years (10/67 died). Multivariate predictors of mortality included alcohol abuse (panorexia nervosa. PMID:23771148

    2016-01-01

    There are some studies in the literature about the feeding behavior and masticatory process in patients with feeding disorders; however, it is not very well known if there are alterations in oral-pharyngeal swallowing dynamics in subjects with anorexia nervosa. To evaluate the oral and pharyngeal bolus transit in patients with anorexia nervosa. The study was conducted with 8 individuals clinically diagnosed and in treatment for restricting-type anorexia nervosa (seven women and one man), and 14 healthy individuals with no digestive or neurological symptoms (10 women, 4 men). Swallows were evaluated by videofluoroscopy with three swallows of 5 mL liquid bolus and three swallows of 5 mL paste bolus consistency, given in a random sequence. The participants were asked after each swallow about the sensation of the bolus passage. In the analysis of oral-pharyngeal transit duration, the mean duration of pharyngeal transit with paste bolus in patients with anorexia was shorter than in healthy volunteers (P=0.02). In the duration of movement of the hyoid bone, longer movement was observed in anorexia than in healthy volunteers with liquid bolus (P=0.01). With liquid bolus, five (62.5%) patients and one (7.1%) control had sensation of the bolus passage (Panorexia nervosa, although the results suggest that pharyngeal transit has shorter duration than that seen in healthy volunteers and the hyoid movement duration is longer in patients than in healthy volunteers. Fast pharyngeal transit may be the cause of bolus transit perception in patients with anorexia nervosa.

  14. [Impaired theory of mind in anorexia nervosa].

    Gál, Zita; Egyed, Katalin; Pászthy, Bea; Németh, Dezsö

    2011-01-01

    Anorexia nervosa (AN) is a severe mental illness, which is characterized by a continuously growing occurrence in the population and by the shift of the onset for earlier ages. The understanding of factors playing role in AN and the importance of effective prevention is an essential issue in science as well as in the society. AN also affects the social domain of life, patients with AN may exhibit impaired social interaction, social isolation, difficulties in emotion recognition and egocentric thinking in cognitive processing. Therefore, the aim of present study was to investigate the theory of mind (ToM) deficits is anorexia nervosa. Although previous studies have reported ToM deficits in autism and in schizophrenia, the number of studies investigating ToM functioning in eating disorders are particularly low. Even though ToM difficulties, such as the affective ToM impairments were found in AN, however, the evidence of cognitive ToM deficits in anorexia patients is still lacking. Twenty anorexia nervosa patients and 20 healthy control adolescent girls participated in the experiment. EDI, BAT, Fallon-Rozin Test and Anamoprhic Micro Body Image Assesment Programme questionnaires and body-image tests were applied to discriminate anorexia nervosa group from healthy control group. The Hungarian version of Faux Pas Recognition Test was applied to evaluate ToM functioning. Compared to healthy control group, impairment in ToM functioning was found in AN group, especially in affective mental state attribution. Our results can raise new aspects for research, therapy and prevention of anorexia nervosa.

  2. Phenotypic profiles of Armenian grape cultivars

    Aroutiounian Rouben

    2015-01-01

    Full Text Available The conservation and sustainable use of grapevine biodiversity in Armenia is particularly important due to the large number of traditional local varieties. Being partially different from European grapevine gene pool, the material of Armenian local cultivars significantly contributes to the understanding of the genetic variation and is valuable source for target selection. During last years many Armenian grapevine cultivars have been already described and their genotypes determined, but some local varieties and wild accessions remain unidentified and their phenotypic characteristics overlooked. The comprehensive analysis of phenotypes is essential for research, including genetic association studies, cultivar evaluation and selection. The goal of our research was the phenotyping on the base of reproductive, carpological and analytical characteristics of 80 Armenian aboriginal and new grape cultivars. Description of phenotypic profiles is important step towards identification and conservation of genetic resources of Armenian grapes. In future, these data can be applied for breeding of improved grape varieties targeted to fresh consumption and wine production.

  3. Study of the evolution of nitrogen compounds during grape ripening. application to differentiate grape varieties and cultivated systems.

    2009-03-25

    The aim of this work was to study the evolution of amino acids and ammonium during grape ripening and to evaluate its application to differentiate grape varieties and cultivated systems (organic and nonorganic). For this purpose, Monastrell, Syrah, Merlot, and Petit Verdot grapes produced using conventional agriculture and Monastrell grape cultivated using organic agriculture, collected during two consecutive harvests at different stages of ripening, were studied. These years of harvest were very different climatic years; even so, the grape varieties presented similar qualitative compositions. Therefore, the percentage of amino acids at harvest moment allowed differentiation of grapes according to variety and cultivated system, regardless of the year. The nitrogen composition could allow estimation of the fermentative aroma potential of grapes. Thus, Syrah was the grape with the greatest aroma potential at harvest. Monastrell nonorganic grape had a concentration of nitrogen compounds superior to that of Monastrell organic grape. In Monastrell, Syrah, and Merlot, traditional varieties in the area, the highest concentration of nitrogen compounds coincided with the highest degrees Baume/total acidity ratio and color index during 2007. Consequently, technological and phenolic maturity of these grape varieties coincided with the maximum composition of nitrogen compounds. However, in 2008, this did not happen because grape ripening was irregular as a consequence of different climatological conditions.

  4. Ortorexia nervosa: reflexões sobre um novo conceito Orthorexia nervosa: reflections about a new concept

    2011-04-01

    Full Text Available Ortorexia nervosa é o termo descrito para o comportamento obsessivo patológico caracterizado pela fixação por saúde alimentar. O quadro ainda não foi oficialmente reconhecido como um transtorno alimentar, mas discute-se o conceito, suas características, interações e sintomas. No presente trabalho foi realizada uma revisão dos vinte e um artigos publicados desde 1997, quando o comportamento da ortorexia nervosa foi inicialmente descrito. Foram apontadas semelhanças e diferenças entre o comportamento alimentar observado na ortorexia nervosa e nos transtornos alimentares mais frequentes (anorexia e bulimia nervosa. Um instrumento foi desen-volvido e validado para detecção do quadro ortoréxico. Os estudos apontam alguns grupos vulneráveis à orto-rexia nervosa: estudantes de medicina, médicos, nutricionistas, pessoas com sintomas de ansiedade, obsessivo-compulsivos e aqueles que supervalorizam o corpo perfeito. A ortorexia nervosa é situada a partir de uma análise dos conceitos de atitude alimentar e alimentação saudável, procurando um foco biopsicossocial para a alimentação adequada e não apenas um foco fisiológico. Não existem estudos investigativos sobre a ortorexia nervosa no Brasil, mas o tema deve ser discutido para alertar os profissionais da área da saúde sobre a existência desse comportamento inadequado e suas possíveis consequências não só para a saúde física e emocional, mas também para a visão de alimentação saudável.Orthorexia nervosa is a new term described as an obsessive pathological behavior characterized by fixation on healthy eating.

  5. Controlled family study of anorexia nervosa and bulimia nervosa: evidence of shared liability and transmission of partial syndromes.

    Strober, M; Freeman, R; Lampert, C; Diamond, J; Kaye, W

    2000-03-01

    Lifetime rates of full and partial anorexia nervosa and bulimia nervosa were determined in first-degree relatives of diagnostically pure proband groups and relatives of matched, never-ill comparison subjects. Rates of each eating disorder were obtained for 1,831 relatives of 504 probands on the basis of personal structured clinical interviews and family history. Best-estimate diagnoses based on all available information were rendered without knowledge of proband status and pedigree identity. Only definite and probable diagnoses were considered. Whereas anorexia nervosa was rare in families of the comparison subjects, full and partial syndromes of anorexia nervosa aggregated in female relatives of both anorexic and bulimic probands. For the full syndrome of anorexia nervosa, the relative risks were 11.3 and 12.3 in female relatives of anorexic and bulimic probands, respectively. Bulimia nervosa was more common than anorexia nervosa in female relatives of comparison subjects, but it, too, aggregated in the families of ill probands; the corresponding relative risks for bulimia nervosa were 4.2 and 4.4 for female relatives of anorexic and bulimic probands, respectively. When partial syndromes of anorexia nervosa and bulimia nervosa were considered, relative risks fell by one-half in each group of ill probands. Both anorexia nervosa and bulimia nervosa are familial. Their cross-transmission in families suggests a common, or shared, familial diathesis. The additional observation that familial aggregation and cross-transmission extend to milder phenotypes suggests the validity of their inclusion in a continuum of familial liability.

  7. Physical methods of resveratrol induction in grapes and grape products - a review

    Triska, J.; Houska, M.

    2012-01-01

    Trans-resveratrol ((E)-3,4',5-trihydroxystilbene) is a substance that is produced by a large number of plants as a phytoalexin. Resveratrol has been credited as being potentially responsible for the ''French paradox'' - the observation that the French have a relatively low incidence of coronary heart disease, even though their diet is high in saturated fats. This review deals with the methods serving for the increase of the resveratrol content in wine products - wine and grape juices. The methods reviewed are UV irradiation of grapes and ozonisation of grapes. The discussed methods describe the ways of increasing resveratrol contents in grapes and wine using ''natural'' methods. Resveratrol is increased endogenously and therefore, it need not be declared as the added substance on the product labels

The grape anthocyanins content (mg/kg of berry fresh weight was maximum in those grapes harvested on September 11 and 16 (804.1 and 822.6 mg/kg, respectively and decreased for grapes harvested in October. However, the results showed that the grapes with the highest anthocyanin concentration did not lead to the highest colored wines. The wines elaborated from grapes harvested on October 16 (671.9 mg of anthocyanins per kg of berry fresh weight had the best chromatic characteristics and better withstood aging in the bottle; the extent of cell wall degradation in overly matured grapes probably facilitated the extraction of phenolic compounds from skins. However, the chromatic quality of wines made from grapes harvested one week later (October 24, the most mature grapes was lower than that from October 16, with lower color intensity (13%lower in the wine elaborated from grapes harvested in October 24 and a percentage of yellow color 6 % higher in this wine.

    This study aimed to investigate theory of mind (ToM) in individuals with bulimia nervosa (BN), an area neglected by empirical research despite social functioning difficulties in this disorder and evidence of ToM deficits in people with anorexia nervosa (AN). ToM was assessed in 48 BN and 34 Eating Disorder Not Otherwise Specified BN-type (EDNOS-BN) outpatients and 57 healthy controls (HCs) using the Reading the Mind in the Eyes and the Reading the Mind in the Films (RMF), an ecologically valid task novel to BN research. Overall performance in BN and EDNOS-BN groups was equivalent to HCs on both tasks. Individuals with BN had enhanced negative emotion recognition on the RMF. Individuals with AN and BN have distinct socio-cognitive profiles. Further research into social cognition is required to establish the link between interpersonal difficulties and psychopathology in people with BN. Copyright © 2011 Wiley Periodicals, Inc.

    In this study Illumina MiSeq was performed to investigate microbial diversity in soil, leaves, grape, grape juice and wine. A total of 1,043,102 fungal Internal Transcribed Spacer (ITS) reads and 2,422,188 high quality bacterial 16S rDNA sequences were used for taxonomic classification, revealed five fungal and eight bacterial phyla. At the genus level, the dominant fungi were Ascomycota, Sordariales, Tetracladium and Geomyces in soil, Aureobasidium and Pleosporaceae in grapes leaves, Aureobasidium in grape and grape juice. The dominant bacteria were Kaistobacter, Arthrobacter, Skermanella and Sphingomonas in soil, Pseudomonas, Acinetobacter and Kaistobacter in grape and grapes leaves, and Oenococcus in grape juice and wine. Principal coordinate analysis showed structural separation between the composition of fungi and bacteria in all samples. This is the first study to understand microbiome population in soil, grape, grapes leaves, grape juice and wine in Xinjiang through High-throughput Sequencing and identify microorganisms like Saccharomyces cerevisiae and Oenococcus spp. that may contribute to the quality and flavor of wine.

  15. Genomics assisted ancestry deconvolution in grape.

    Jason Sawler

    Full Text Available The genus Vitis (the grapevine is a group of highly diverse, diploid woody perennial vines consisting of approximately 60 species from across the northern hemisphere. It is the world's most valuable horticultural crop with ~8 million hectares planted, most of which is processed into wine. To gain insights into the use of wild Vitis species during the past century of interspecific grape breeding and to provide a foundation for marker-assisted breeding programmes, we present a principal components analysis (PCA based ancestry estimation method to calculate admixture proportions of hybrid grapes in the United States Department of Agriculture grape germplasm collection using genome-wide polymorphism data. We find that grape breeders have backcrossed to both the domesticated V. vinifera and wild Vitis species and that reasonably accurate genome-wide ancestry estimation can be performed on interspecific Vitis hybrids using a panel of fewer than 50 ancestry informative markers (AIMs. We compare measures of ancestry informativeness used in selecting SNP panels for two-way admixture estimation, and verify the accuracy of our method on simulated populations of admixed offspring. Our method of ancestry deconvolution provides a first step towards selection at the seed or seedling stage for desirable admixture profiles, which will facilitate marker-assisted breeding that aims to introgress traits from wild Vitis species while retaining the desirable characteristics of elite V. vinifera cultivars.

    The aim of the article was an attempt to present selected theoretical motifs and moreover self experience in the adaptation of elements of psychodrama by Moreno in psychodynamic psychotherapy (individual and group psychotherapy) in a group of people with anorexia and bulimia nervosa. Psychodrama through own creativity, spontaneity and taking action on the "here and now" stage helps to attain and intensify therapeutic aims which concern the consciousness of inner conflict of persons with anorexia and bulimia nervosa, which is translocated on their body.

  2. Endocrine Dysregulation in Anorexia Nervosa Update

    2011-01-01

    Context: Anorexia nervosa is a primary psychiatric disorder with serious endocrine consequences, including dysregulation of the gonadal, adrenal, and GH axes, and severe bone loss. This Update reviews recent advances in the understanding of the endocrine dysregulation observed in this state of chronic starvation, as well as the mechanisms underlying the disease itself. Evidence Acquisition: Findings of this update are based on a PubMed search and the author's knowledge of this field. Evidence Synthesis: Recent studies have provided insights into the mechanisms underlying endocrine dysregulation in states of chronic starvation as well as the etiology of anorexia nervosa itself. This includes a more complex understanding of the pathophysiologic bases of hypogonadism, hypercortisolemia, GH resistance, appetite regulation, and bone loss. Nevertheless, the etiology of the disease remains largely unknown, and effective therapies for the endocrine complications and for the disease itself are lacking. Conclusions: Despite significant progress in the field, further research is needed to elucidate the mechanisms underlying the development of anorexia nervosa and its endocrine complications. Such investigations promise to yield important advances in the therapeutic approach to this disease as well as to the understanding of the regulation of endocrine function, skeletal biology, and appetite regulation.

  3. Refeeding Hypophosphatemia in Adolescents With Anorexia Nervosa

    Nicholls, Dasha

    2013-01-01

    The rate of adolescents presenting with anorexia nervosa (AN) is increasing. Medically unstable adolescents are admitted to the hospital for nutrition restoration. A lack of global consensus on appropriate refeeding practices of malnourished patients has resulted in inconsistent refeeding practices. Refeeding hypophosphatemia (RH) is the most common complication associated with refeeding the malnourished patient. This review sought to identify the range of refeeding rates adopted globally and the implication that total energy intake and malnutrition may have on RH while refeeding adolescents with anorexia nervosa. Studies were identified by a systematic electronic search of medical databases from 1980 to September 2012. Seventeen publications were identified, including 6 chart reviews, 1 observational study, and 10 case reports, with a total of 1039 subjects. The average refeeding energy intake was 1186 kcal/d, ranging from 125–1900 kcal/d, with a mean percentage median body mass index (% mBMI) of 78%. The average incidence rate of RH was 14%. A significant correlation between malnutrition (% mBMI) and post-refeeding phosphate was identified (R 2 = 0.6, P = .01). This review highlights the disparity in refeeding rates adopted internationally in treating malnourished adolescents with anorexia nervosa. Based on this review, the severity of malnutrition seems to be a marker for the development of RH more so than total energy intake. PMID:23459608

  4. Association of CNR1 and FAAH endocannabinoid gene polymorphisms with anorexia nervosa and bulimia nervosa: evidence for synergistic effects.

    Endocannabinoids modulate eating behavior; hence, endocannabinoid genes may contribute to the biological vulnerability to eating disorders. The rs1049353 (1359 G/A) single nucleotide polymorphism (SNP) of the gene coding the endocannabinoid CB1 receptor (CNR1) and the rs324420 (cDNA 385C to A) SNP of the gene coding fatty acid amide hydrolase (FAAH), the major degrading enzyme of endocannabinoids, have been suggested to have functional effects on mature proteins. Therefore, we explored the possibility that those SNPs were associated to anorexia nervosa and/or bulimia nervosa. The distributions of the CNR1 1359 G/A SNP and of the FAAH cDNA 385C to A SNP were investigated in 134 patients with anorexia nervosa, 180 patients with bulimia nervosa and 148 normal weight healthy controls. Additive effects of the two SNPs in the genetic susceptibility to anorexia nervosa and bulimia nervosa were also tested. As compared to healthy controls, anorexic and bulimic patients showed significantly higher frequencies of the AG genotype and the A allele of the CNR1 1359 G/A SNP. Similarly, the AC genotype and the A allele of the FAAH cDNA 385C to A SNP were significantly more frequent in anorexic and bulimic individuals. A synergistic effect of the two SNPs was evident in anorexia nervosa but not in bulimia nervosa. Present findings show for the first time that the CNR1 1359 G/A SNP and the FAAH cDNA 385C to A SNP are significantly associated to anorexia nervosa and bulimia nervosa, and demonstrate a synergistic effect of the two SNPs in anorexia nervosa.

Grape berries, as ‘sink organs,’ rely on the use of available carbohydrate resources produced by photosynthesis to support their development and composition. A high throughput two-dimensional gel electrophoresis (2-DE was conducted on muscadine (Vitis rotundifolia grape leaf proteins to document complexity in their composition and to determine protein identity and function for enhancing photosynthetic efficiency of muscadine grape. 2-DE resolved muscadine leaf proteins into >258 polypeptides with pIs between 3.5 and 8.0 and molecular weight between 12,000 to 15,0000 Daltons. The consistently expressed proteins were excised and subjected to sequencing. Homology search of protein sequences showed 84% identity with Viridi plantae database. Identity of some of these proteins included RuBisCO, glutamine synthetase, pathogenesis-related protein, glyoxisomal malate dehydrogenase, ribonucleoprotein, chloroplast precursor, oxygen evolving enhancer protein. Comparative analysis of 10 muscadine cultivars showed quantitative differences in expression of 39 polypeptides among these genotypes. The results suggested that the polypeptide composition of muscadine grape leaf is complex, and polypeptide number and amount vary widely among muscadine genotypes, and these variations may be responsible for differences in their physiology, berry and stress tolerance characteristics.Keywords: grapevine, leaves, muscadine, proteins, sequencing, 2-DE

  7. Instagram use is linked to increased symptoms of orthorexia nervosa.

    Turner, Pixie G; Lefevre, Carmen E

    2017-06-01

    Social media use is ever increasing amongst young adults and has previously been shown to have negative effects on body image, depression, social comparison, and disordered eating. One eating disorder of interest in this context is orthorexia nervosa, an obsession with eating healthily. High orthorexia nervosa prevalence has been found in populations who take an active interest in their health and body and is frequently comorbid with anorexia nervosa. Here, we investigate links between social media use, in particularly Instagram and orthorexia nervosa symptoms. We conducted an online survey of social media users (N = 680) following health food accounts. We assessed their social media use, eating behaviours, and orthorexia nervosa symptoms using the ORTO-15 inventory. Higher Instagram use was associated with a greater tendency towards orthorexia nervosa, with no other social media channel having this effect. In exploratory analyses Twitter showed a small positive association with orthorexia symptoms. BMI and age had no association with orthorexia nervosa. The prevalence of orthorexia nervosa among the study population was 49%, which is significantly higher than the general population (Instagram has a high prevalence of orthorexia symptoms, with higher Instagram use being linked to increased symptoms. These findings highlight the implications social media can have on psychological wellbeing, and the influence social media 'celebrities' may have over hundreds of thousands of individuals. These results may also have clinical implications for eating disorder development and recovery.

  17. Distribution of Wild and Cultivated Grapes in Turkey

    Ibrahim H UZUN

    2010-12-01

    Full Text Available Turkey is one of main gene centers in the world for grapes. It is believed that cultivated grapes have their origins in Turkey and the surrounding countries. Vitis vinifera ssp sylvestris is the only wild grape species in this region. That is why Turkey has a very large amount of wild grapevine populations and grape cultivars which offer to grapevine breeders a valuable gene pool. Wild grapevines have significant characters for inducing the resistence to biotic and abiotic stress factors, such as resistance to lime, drought, pests and diseases. Turkey has over 1.600 local grape cultivars, among which the majority of them are conserved at the national grape collection vineyard in Tekirda?. They are mostly used as table grapes, dried grapes or for local consumptions. Wild grapes are distributed all over the country territory, mainly in the river basins and forests. Wild grape collection vineyards were established at some universities in Turkey. These grapevines will be screened for the resistance to biotic and abiotic stress factors.

    Sagdic, Osman; Ozturk, Ismet; Yilmaz, Mustafa Tahsin; Yetim, Hasan

    2011-09-01

    Grape pomace extracts were obtained from 5 different grape varieties grown in Turkey. The extracts were concentrated to obtain crude extracts; and incorporated into beef patties at 0% (Control), 1%, 2%, 5%, and 10% concentrations to test their antimicrobial effects in different storage periods (first, 12, 24, and 48 h). The numbers of microorganism were generally decreased by the extract concentration during the storage period. All the microorganisms tested were inhibited by the extract concentration of 10% in all the storage periods. Furthermore, the foodborne pathogens including Enterobacteriaceae and coliform bacteria, and the spoilage microorganisms including yeasts and moulds and lipolytic bacteria were also inhibited by 5% of Emir, Gamay, and Kalecik Karasi varieties in beef patties. Considering the results, the extracts of grape pomaces might be a good choice in the microbial shelf life extension of the food products as well as inhibiting the food pathogens as the case of beef patties. Grape pomace consists of seeds, skins, and stems, and an important by-product that is well known to be the rich source of phenolic compounds, both flavonoids and non-flavonoids. These substances have considerable beneficial effects on human health. The use of natural antimicrobial compounds, like plant extracts of herbs and spices for the preservation of foods has been very popular issue because of their antimicrobial activity. Therefore, grape pomace should be added into some food formulations to benefit from their protective effects. In this respect, this study reports the effect of addition of grape pomace extracts obtained from different grape varieties on microbial quality of beef patty. The results obtained in this study may be useful for food industry, which has recently tended to use natural antimicrobial sources in place of synthetic preservatives to prevent microbial spoilage. © 2011 Institute of Food Technologists®

    2011-06-01

    Objective To compare the electrocortical processing of food pictures in participants with anorexia nervosa (n = 21), bulimia nervosa (n = 22), and healthy controls (HCs) (n = 32) by measuring the early posterior negativity, an event-related potential that reflects stimulus salience and selective attention. Methods We exposed these three groups to a rapid stream of high- and low-calorie food pictures, as well as standard emotional and neutral pictures. Results Event-related potentials in the time range of 220 milliseconds to 310 milliseconds on posterior electrodes differed between groups: patients with eating disorders showed facilitated processing of both high- and low-calorie food pictures relative to neutral pictures, whereas HC participants did so only for the high-calorie pictures. Subjective palatability of the pictures was rated highest by patients with anorexia nervosa, followed by the HC and bulimia nervosa groups. Conclusions Patients with eating disorders show a generalized attentional bias for food images, regardless of caloric value. This might explain the persistent preoccupation with food in these individuals.

    Vitamin D3 has been described to have different extraskeletal roles by acting as parahormone in obesity, diabetes, cancer, cognitive impairment, and dementia and to have important regulatory functions in innate immunity. There are no studies showing extraskeletal changes associated with hypovitaminosis D3 in eating disorders. Methods. We have analyzed the blood of 18 patients affected by anorexia nervosa and bulimia nervosa collected over a 15-month period. We performed a panel of chemical and clinical analyses: the assay of vitamin D3, the immunoblotting of vitamin D receptor and peroxisome proliferator-activated receptor gamma, and the genotyping of 5-hydroxytryptamine transporter linked polymorphic region. Results. We choose 18 patients with a normal blood test profile such as thyroid hormones, hepatic and renal parameters, triglycerides, proteins, vitamin B12, and folic acid. Among these emerged the case of a woman with long-term anorexia nervosa and the case of a woman with long-term bulimia nervosa both complicated by anxiety and depression, severe hypovitaminosis D3, decrease of vitamin D receptor, leukopenia, and 5-hydroxytryptamine transporter linked polymorphic region short allele. Conclusion. The results induce hypothesising that the severe hypovitaminosis D3 might be responsible for the lack of the inflammatory response and the depressive symptoms in patients with long-term eating disorders.

    2010-12-01

    Full Text Available Viticultural practices in the State of Santa Catarina, Brazil, have shown economic growth, with the production of grapes used to produce wines and grape juice. Grapes are rich in phenolic compounds which have drawn attention not only because of their important role in the development of products derived from grapes, but also for their potential beneficial health effects. The objective of this study was to evaluate commercial, organic and homemade grape juices produced in Santa Catarina. Grape juices were analyzed for total phenolic content, colour, and antioxidant activity. The commercial juices had the highest average values for total monomeric anthocyanins and total phenolics. There was a strong positive correlation (R = 0.9566 between the antioxidant activity and total phenolic content for the commercial juice. In addition, the Principle Components Analysis showed a strong positive correlation between the red colour and total monomeric anthocyanins. However, the total monomeric anthocyanis and polymeric anthocyanins showed a negative correlation.

    Eating disorders are characterized by changes in eating patterns associated with a series of psychosocial conflicts, low self-esteem and poor empathy, and an obsession with slimming. The aims of the present study were: 1. To determinate the prevalence of anorexia nervosa, bulimia nervosa and other eating disorders in a representative sample of adolescent girls between the ages of 12 and 21 living in the city of Reus (Spain). 2. To evaluate the association between eating disorders and alterations on the Eating Attitudes Test-40 (EAT-40), Body Attitudes Test (BAT), and the Aesthetic Body Shape Questionnaire (CIMEC). We performed a cross-sectional observational study in a random sample of adolescent girls aged between 12 and 21 years old. Information was gathered from a structured questionnaire on demographic and anthropometric factors (age, place of birth, education, etc.), clinical examination, clinical interview, DMS-IV diagnostic criteria, and three self-administered tests: EAT-40, BAT and CIMEC. A total of 551 adolescents were analyzed. The mean age was 17.6+/-2.5 years. Diagnostic criteria of anorexia nervosa were found in 0.9% (95% CI: 0.4-2.4), bulimia nervosa in 2.9% (95% CI: 1.7-4.7), and other eating disorders in 5.3% (95% CI: 3.6-7.5). The test showing the greatest alterations was the CIMEC (38%), followed by the BAT (27.1%) and EAT-40 (23.1%). All the adolescents that met the diagnostic criteria of anorexia nervosa showed alterations in all three tests. The high prevalence of eating disorders indicates the need for greater direct involvement among health professionals. The EAT-40, BAT and CIMEC are effective screening instruments for these disorders.

The three variants of compost piles formed from grape pomace and vegetables waste, wood chips and mature in varying proportions were tested. Turning of piles was performed using windrow turner PKS 2.8, in which the achieved performance was monitored. On the performance of windrow turner has a significant influence also cross section or width and height of turning piles and the bulk density of ingredients including their moisture. In evaluating, attention has been paid to assessment of selected parameters (temperature, moisture content of the composting process. From the viewpoint of temperature course, the highest temperature reached at the piles in Var. I (64.1 °C and Var. II (55.3 °C. Moisture of compost piles in the individual variants did not differ significantly and ranged between 25–35%.

    Georgiev, Vasil; Ananga, Anthony; Tsolova, Violeta

    2014-01-01

    Grape is one of the oldest fruit crops domesticated by humans. The numerous uses of grape in making wine, beverages, jelly, and other products, has made it one of the most economically important plants worldwide. The complex phytochemistry of the berry is characterized by a wide variety of compounds, most of which have been demonstrated to have therapeutic or health promoting properties. Among them, flavonoids are the most abundant and widely studied, and have enjoyed greater attention among grape researchers in the last century. Recent studies have shown that the beneficial health effects promoted by consumption of grape and grape products are attributed to the unique mix of polyphenolic compounds. As the largest group of grape polyphenols, flavonoids are the main candidates considered to have biological properties, including but not limited to antioxidant, anti-inflammatory, anti-cancer, antimicrobial, antiviral, cardioprotective, neuroprotective, and hepatoprotective activities. Here, we discuss the recent scientific advances supporting the beneficial health qualities of grape and grape-derived products, mechanisms of their biological activity, bioavailability, and their uses as nutraceuticals. The advantages of modern plant cell based biotechnology as an alternative method for production of grape nutraceuticals and improvement of their health qualities are also discussed. PMID:24451310

    2014-02-01

    Full Text Available Heat treatment is a well-known process in food preservation. It is made to avoid and to slow down food deterioration. The process was developed by Louise Pasteur French scientist to avoid late among others wine further fermentation. The different heat treatments influence the shelf life in food production. In our article we present the process of grape must fermentation, as grape must is the base material of wine production. The treatment of harvested fresh grape juice has a big influence on end product quality. It is our experiments we examined the same grape must with four different methods in closed and in open spaces to determine CO2 concentration change. There are four different methods for treatment of grape juice: boiling, microwave treatment, treatment by water bath thermostat and a control without treatment. As a result of the comparison it can be stated that the heat treatment delays the start of fermentation, thereby increasing shelf life of grape must. However, no significant differences were found between two fermentation of heat-treated grape must by the microwave and water-bath thermostat. The different heat treatment of grape must base materials was done at the laboratory in Faculty of Mechanical Engineering of Szent István University.

  10. Sustainability of grape-ethanol energy chain

    Ester Foppa Pedretti

    2014-11-01

    Full Text Available The aim of this work is to evaluate the sustainability, in terms of greenhouse gases emission saving, of a new potential bio-ethanol production chain in comparison with the most common ones. The innovation consists of producing bio-ethanol from different types of no-food grapes, while usually bio-ethanol is obtained from matrices taken away from crop for food destination: sugar cane, corn, wheat, sugar beet. In the past, breeding programs were conducted with the aim of improving grapevine characteristics, a large number of hybrid vine varieties were produced and are nowadays present in the Viticulture Research Centre (CRA-VIT Germplasm Collection. Some of them are potentially interesting for bio-energy production because of their high production of sugar, good resistance to diseases, and ability to grow in marginal lands. Life cycle assessment (LCA of grape ethanol energy chain was performed following two different methods: i using the spreadsheet BioGrace, developed within the Intelligent Energy Europe program to support and to ease the Renewable Energy Directive 2009/28/EC implementation; ii using a dedicated LCA software. Emissions were expressed in CO2 equivalent (CO2eq. These two tools gave very similar results. The overall emissions impact of ethanol production from grapes on average is about 33 g CO2eq MJ–1 of ethanol if prunings are used for steam production and 53 g CO2eq MJ–1 of ethanol if methane is used. The comparison with other bio-energy chains points out that the production of ethanol using grapes represents an intermediate situation in terms of general emissions among the different production chains. The results showed that the sustainability limits provided by the normative are respected to this day. On the contrary, from 2017 this production will be sustainable only if the transformation processes will be performed using renewable sources of energy.

  11. Total phenolic contents and free-radical scavenging activities of grape (Vitis vinifera L.) and grape products.

    Keser, Serhat; Celik, Sait; Turkoglu, Semra

    2013-03-01

    Grape is one of the world's largest fruit crops, with an approximate annual production of 58 million metric tons, and it is well known that the grape skins, seeds and stems, waste products generated during wine and grape juice processing, are rich sources of polyphenols. It contains flavonoids, phenolic acids and stilbenes. In this study, we tried to determine antioxidant properties and phenolic contents of grape and grape products (fresh fruit, seed, dried fruit, molasses, pestil, vinegar) of ethanol and water extracts. Antioxidant properties of extracts were investigated by DPPH(√), ABTS(√+), superoxide, H(2)O(2) scavenging, reducing power, metal chelating activity and determination of total phenolic contents. The seed extracts revealed highest ABTS(√+), DPPH(√), H(2)O(2) scavenging and reducing power activities. Furthermore, these extracts showed higher total phenolic contents than other grape product extracts.

  12. Endocrinology of anorexia nervosa in young people: recent insights

    Singhal, Vibha; Misra, Madhusmita; Klibanski, Anne

    2014-01-01

    Purpose of review Anorexia nervosa is among the most prevalent chronic medical conditions in young adults. It has acute as well as long-term consequences, some of which, such as low bone mineral density (BMD), are not completely reversible even after weight restoration. This review discusses our current understanding of endocrine consequences of anorexia nervosa. Recent findings Anorexia nervosa is characterized by changes in multiple neuroendocrine axes including acquired hypogonadotropic hypogonadism, growth hormone resistance with low insulin-like growth factor-1 (likely mediated by fibroblast growth factor-1), relative hypercortisolemia, alterations in adipokines such as leptin, adiponectin and resistin, and gut peptides including ghrelin, PYY and amylin. These changes in turn contribute to low BMD. Studies in anorexia nervosa have demonstrated abnormalities in bone microarchitecture and strength, and an association between increased marrow fat and decreased BMD. One study in adolescents reported an improvement in BMD following physiologic estrogen replacement, and another in adults demonstrated improved BMD following risedronate administration. Brown adipose tissue is reduced in anorexia nervosa, consistent with an adaptive response to the energy deficit state. Summary Anorexia nervosa is associated with widespread physiologic adaptations to the underlying state of undernutrition. Hormonal changes in anorexia nervosa affect BMD adversely. Further investigation is underway to optimize therapeutic strategies for low BMD. PMID:24275621

  13. Socio-cultural factors in the development of anorexia nervosa.

    Garner, D M; Garfinkel, P E

    1980-11-01

    A population of professional dance (N = 183) and modelling (N = 56) students, who by career choice must focus increased attention and control over their body shapes, was studied. Height and weight data were obtained on all subjects. In addition, a questionnaire that is useful in assessing the symptoms of anorexia nervosa, the Eating Attitudes Test (EAT), was administered. Results of these tests were compared with those of normal female university students (N = 59), patients with anorexia nervosa (N = 68), and music students (N = 35). Anorexia nervosa and excessive dieting concerns were overrepresented in the dance and modelling students. Twelve cases (6.5%) of primary anorexia nervosa were detected in the dance group. All but one case developed the disorder while studying dance. Within the dance group those from the most competitive environments had the greatest frequency of anorexia nervosa. These data suggest that both pressures to be slim and achievement expectations are risk factors in the development of anorexia nervosa. The influence of socio-cultural determinants are discussed within the context of anorexia nervosa as a multidetermined disorder.

  14. Anorexia nervosa: slow regain of bone mass.

    Valla, A; Groenning, I L; Syversen, U; Hoeiseth, A

    2000-01-01

    In a retrospective study of women aged 18-30 years, aimed at assessing factors associated with peak bone mass (PBM), 13 of 239 study cases reported having had anorexia nervosa. The mean total femoral and lumbar bone mineral density (BMD) values were not significantly lower in women who had had anorexia than in the pooled group (mean Z-scores of -0.60 and -0.48). Cases with less than 6 years since the anorexia had on average a present weight 5.7 kg less than their premorbid weights, while cases with more than 6 years since the eating disorder had an average weight 22.5 kg above their pre-morbid weights. The cases who had not regained their weight had BMD values significantly lower than the pooled material (mean Z-scores -1.15 and -0.9 in the lumbar spine and total femur respectively). Those who had regained their weight had BMD values as predicted from their present anthropometric data, while those who had not regained their weight had BMD values that were substantially below that predicted from their present weight. Anorexia nervosa seems to be associated with a low BMD which is even lower than that which can be predicted from the weight loss alone. This suggests that weight loss and other factors, such as menstrual dysfunction and estrogen deficiency, are independent and thus additive causes of bone loss in anorexia nervosa. Recovery of BMD seems slow, but the BMD may become as predicted from the anthropometric data after restoration of body weight and menses. The potential for recovery of BMD seems intact for several years after menarche.

  15. Neuroendocrine and Metabolic Disorders in Bulimia Nervosa.

    Milano, Walter; Capasso, Anna

    2017-12-11

    Bulimia nervosa, is an eating disorder characterized by excessive influence of weight and body shape on the levels of self-esteem, with pervasive feelings of failure and inadequacy. The eating is characterized by the presence of episodes of uncontrolled eating (Binge), during which the person ingests mass wide variety of foods and the feeling of not being able to stop eating. This review focuses on the metabolic and hormonal alterations in the in bulimia nervosa. A literature search was conducted using the electronic database Medline and PubMed and with additional hand searches through the reference list obtained from the articles found. Journal were searched up to 2015. Inclusion criteria were: 1) full text available in English; 2) published in a peer-reviewed journal and using the following keywords: neurotrasmitters (AgRP, BDNF, αMSH, NP Y, endocannabinoids, adiponectin, CCK, ghrelin, GLP-1, insulin, leptin, PP, PYY), hormones (FSH, LH, estrogen, progesterone, testosterone) and bulimia nervosa, eating disorders. All data reported in the present review indicated that changes in the central and peripheral neuroendocrine equilibria may favor the onset and influence the course and prognosis of an DA. However, it is still questionable whether the alterations of the peptides and hormones regulating the mechanisms of eating behavior are the cause or consequence of a compromised diet. The results of the present review indicate that the altered balance of the various peptides or hormones can be relevant not only for the genesis and / or maintenance of altered dietary behaviors, but also for the development of specific psychopathological aspects in eating disorders.

  16. Defining recovery in adult bulimia nervosa.

    Yu, Jessica; Agras, W Stewart; Bryson, Susan

    2013-01-01

    To examine how different definitions of recovery lead to varying rates of recovery, maintenance of recovery, and relapse in bulimia nervosa (BN), end-of-treatment (EOT) and follow-up data were obtained from 96 adults with BN. Combining behavioral, physical, and psychological criteria led to recovery rates between 15.5% and 34.4% at EOT, though relapse was approximately 50%. Combining these criteria and requiring abstinence from binge eating and purging when defining recovery may lead to lower recovery rates than those found in previous studies; however, a strength of this definition is that individuals who meet this criteria have no remaining disordered behaviors or symptoms.

  17. [The refeeding syndrome in anorexia nervosa].

    Ibrahim, Iman Badr; Hussain, Alia Arif; Sjögren, Jan Magnus

    2018-04-30

    The refeeding syndrome (RFS) is a potentially fatal condition involving fluid and electrolyte imbalances after refeeding in patients with anorexia nervosa. Low-calorie diet added thiamine and minerals is the standard approach to prevent RFS. In a recent systematic review starting with a higher calorie amount than earlier has been recommended, and in another review, it is proposed that a restriction in the amount of carbohydrates may allow for a higher calorie intake early on to enable a safe and faster weight gain. There are still many unanswered questions, but these studies may point to a future change in the guidelines.

  19. Can cognitive exercises help treat anorexia nervosa?

    Tchanturia, K; Whitney, J; Treasure, J

    2006-12-01

    Cognitive remediation therapy (CRT) is used as an intervention for people with brain lesions and psychosis. This case report demonstrates the possible benefits of introducing CRT into treatment packages for anorexia nervosa (AN). In our previous work, we reported that people with AN demonstrate inflexibility in cognitive set-shifting tasks. Weight gain alone does not improve the neuropsychological profile in set-shifting tasks. This case report illustrates how training programmes can address problems in cognitive rigidity. We acknowledge the limitations of case studies, however, this is a starting point in exploring the possibilities of introducing CRT as part of the treatment of AN.

  1. Applying neurobiology to the treatment of adults with anorexia nervosa.

    Hill, Laura; Peck, Stephanie Knatz; Wierenga, Christina E; Kaye, Walter H

    2016-01-01

    Anorexia nervosa is a severe, biologically based brain disorder with significant medical complications. It is critical that new, effective treatments are developed to interrupt the persistent course of the illness due to the medical and psychological sequelae. Several psychosocial, behavioral and pharmacologic interventions have been investigated in adult anorexia nervosa; however, evidence shows that their impact is weak and treatment effects are generally small. This paper describes a new neurobiological anorexia nervosa model that shifts focus from solely external influences, such as social and family, to include internal influences that integrate genetic and neurobiological contributions, across the age span. The model serves as a theoretical structure for a new, five-day treatment, outlined in this paper, targeting anorexia nervosa temperament, which integrates neurobiological dimensions into evidence-based treatment interventions. The treatment is in two phases. Phase I is a five day, 40 hour treatment for anorexia nervosa adults. Phase II is the follow-up and is currently being developed. Preliminary qualitative acceptability data on 37 adults with anorexia nervosa and 60 supports (e.g., spouses, parents, aunts, friends, partners, children of anorexia nervosa adults) are promising from Phase I. Clients with anorexia nervosa and their supports report that learning neurobiological facts improved their understanding of the illness and helped equip them with better tools to manage anorexia nervosa traits and symptoms. In addition, nutritional knowledge changed significantly. This is the first neurobiologically based, five-day treatment for adults with anorexia nervosa and their supports. It is a new model that outlines underlying genetic and neurobiological contributions to anorexia nervosa that serves as a foundation to treat both traits and symptoms. Preliminary qualitative findings are promising, with both clients and supports reporting that the

    2000-09-01

    A 27-year-old woman had been suffering from bulimia and habitual vomiting for about 7 years and was incidentally found to have right renal stones by computed tomography. She was referred to our hospital for the treatment of these caluculi. On admission, she presented with hypokalemia, hypochloremia and metabolic alkalosis and was diagnosed with anorexia nervosa. Following successful removal by percutaneous nephrolithotripsy and extracorporeal shockwave lithotripsy the stones were found to consist of pure ammonium urate. Since the urine of an anorexia nervosa patient tends to be rich in uric acid and ammonium, anorexia nervosa seems to be associated with ammonium urate urinary stones.

  3. Underlying assumptions and core beliefs in anorexia nervosa and dieting.

    Cooper, M; Turner, H

    2000-06-01

    To investigate assumptions and beliefs in anorexia nervosa and dieting. The Eating Disorder Belief Questionnaire (EDBQ), was administered to patients with anorexia nervosa, dieters and female controls. The patients scored more highly than the other two groups on assumptions about weight and shape, assumptions about eating and negative self-beliefs. The dieters scored more highly than the female controls on assumptions about weight and shape. The cognitive content of anorexia nervosa (both assumptions and negative self-beliefs) differs from that found in dieting. Assumptions about weight and shape may also distinguish dieters from female controls.

  4. The development of global GRAPES 4DVAR

    Liu, Yongzhu

    2017-04-01

    Four-dimensional variation data assimilation (4DVAR) has given a great contribution to the improvement of NWP system over the past twenty years. Therefore, our strategy is to develop an operational global 4D-Var system from the outset. The aim at the paper is to introduce the development of the global GRAPES four-dimensional variation data assimilation (4DVAR) using incremental analysis schemes and to presents results of a comparison between 4DVAR using 6-hour assimilation window and simplified physics during the minimization with three-dimensional variation data assimilation (3DVAR). The dynamical cores of the tangent-linear and adjoint models are developed directly based on the non-hydrostatic forecast model. In addition, the standard correctness checks have been performed. As well as the development adjoint codes, most of our work is focused on improving the computational efficiency since the bulk of the computational cost of 4D-Var is in the integration of the tangent-linear and adjoint models. In terms of tangent-linear model, the wall-clock time is reduced to about 1.2 times as much as one of nonlinear model through the optimizing of the software framework. The significant computational cost savings on adjoint model result from the removing the redundant recompilations of model trajectories. It is encouraging that the wall-clock time of adjoint model is less than 1.5 times as much as one of nonlinear model. The current difficulty is that the numerical scheme used within the linear model is based on strategically on the numeric of the corresponding nonlinear model. Further computational acceleration should be expected from the improvement on nonlinear numerical algorithm. A series of linearized physical parameterization schemes has been developed to improve the representation of perturbed fields in the linear model. It consists of horizontal and vertical diffusion, sub-grid scale orographic gravity wave drag, large-scale condensation and cumulus convection

  5. Alterations in brain structures related to taste reward circuitry in ill and recovered anorexia nervosa and in bulimia nervosa.

    Frank, Guido K; Shott, Megan E; Hagman, Jennifer O; Mittal, Vijay A

    2013-10-01

    The pathophysiology of anorexia nervosa remains obscure, but structural brain alterations could be functionally important biomarkers. The authors assessed taste pleasantness and reward sensitivity in relation to brain structure, which may be related to food avoidance commonly seen in eating disorders. The authors used structural MR imaging to study gray and white matter volumes in women with current restricting-type anorexia nervosa (N=19), women recovered from restricting-type anorexia nervosa (N=24), women with bulimia nervosa (N=19), and healthy comparison women (N=24). All eating disorder groups exhibited increased gray matter volume of the medial orbitofrontal cortex (gyrus rectus). Manual tracing confirmed larger gyrus rectus volume, and volume predicted taste pleasantness ratings across all groups. Analyses also indicated other morphological differences between diagnostic categories. Antero-ventral insula gray matter volumes were increased on the right side in the anorexia nervosa and recovered anorexia nervosa groups and on the left side in the bulimia nervosa group relative to the healthy comparison group. Dorsal striatum volumes were reduced in the recovered anorexia nervosa and bulimia nervosa groups and predicted sensitivity to reward in all three eating disorder groups. The eating disorder groups also showed reduced white matter in right temporal and parietal areas relative to the healthy comparison group. The results held when a range of covariates, such as age, depression, anxiety, and medications, were controlled for. Brain structure in the medial orbitofrontal cortex, insula, and striatum is altered in eating disorders and suggests altered brain circuitry that has been associated with taste pleasantness and reward value.

    Full Text Available Os autores apresentam uma revisão de alguns pontos de vista com relação à anorexia nervosa. Alinham-se aspectos classificatórios, históricos, clínicos e terapêuticos. Reconhecida como a base para ocorrências místicas na Idade Média, foi entendida como uma apresentação histérica no século XVII, para tornar-se, logo em seguida, objeto das indagações freudianas. Discute-se a anorexia como uma apresentação da estrutura histérica, aqui abordada a partir dos conceitos freudianos sobre histeria, Édipo e feminino, e considerando-se o corpo físico como um mero suporte para articulações simbólicas. Para Freud, a anorexia nervosa seria um quadro pelo qual a histérica exprime sua aversão à sexualidade.

  7. [Anorexia nervosa: a model of malnutrition].

    Rigaud, D

    2000-11-01

    Anorexia nervosa is a typical kind of malnutrition resulting from chronic starvation. The malnutrition is related to a severe eating disorder (fear of eating and becoming fat) causing reduction of food intake. The large majority of the patients are women (95%). There are two types of anorexia nervosa with different prognosis and treatment: the restricting type and the "purging" type (with or without bulimia). In this kind of malnutrition, plasma nutritional markers are normal. The decrease in energy intake induces an adaptative decrease in energy expenditure. Body weight loss is related to a loss in fat free mass and in fat mass, although there is an increase in extracellular water. Below a body mass index of 15 kg/(m)(2), sodium and water retention require prescription of a low sodium diet. Several factors of resistance are operating in this disease, acting against body weight gain: metabolic wasting of energy expenditure (futile cycles), fear-related energy expenditure, dissimulations. Recovery is still long and difficult to obtain and requires a combined nutritional and psychotherapeutic approach.

  8. Mitochondrial Neurogastrointestinal Encephalomyopathy Presenting as Anorexia Nervosa.

    Demaria, Francesco; De Crescenzo, Franco; Caramadre, Anna Maria; D'Amico, Adele; Diamanti, Antonella; Fattori, Fabiana; Casini, Maria Pia; Vicari, Stefano

    2016-12-01

    Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare multisystemic autosomal recessive disorder mainly caused by mutations in the nuclear gene TYMP, encoding thymidine phosphorylase. It generally appears in childhood and is clinically characterized by severe gastrointestinal dysmotility, cachexia, ptosis, progressive external ophthalmoplegia, peripheral neuropathy, and diffuse leukoencephalopathy on brain magnetic resonance imaging. The disease is clinically heterogeneous with the main symptoms being gastrointestinal, with an important weight loss. Symptoms might worsen rapidly, and a timely diagnosis is vital. However, patients report retrospectively their first symptoms before the age of 12 years, but the delay in diagnosis varies from 5 to 10 years. In the present study, we report a case of an adolescent with MNGIE, which was initially, and erroneously, diagnosed as anorexia nervosa. To make a timely and accurate differential diagnosis, we will discuss the clinical differences and similarities between MNGIE and anorexia nervosa and the importance of a multidisciplinary evaluation.

  9. Outcome, comorbidity and prognosis in anorexia nervosa.

    Jagielska, Gabriela; Kacperska, Iwona

    2017-04-30

    Anorexia nervosa (AN) is a relatively common disorder, especially in adolescent and young adult women. The lifetime prevalence of AN in females ranges from 1.2 to 2.2%. The prevalence in males is 10-times lower. The condition is associated with a high risk of chronic course and poor prognosis in terms of treatment and the risk of death. Longer follow-up periods seemed to correspond with increased improvement rates and increased mortality. Onset of the disorder during adolescence is associated with better prognosis. It is reported that as much as 70% to over 80% of patients in this age group achieve remission. Worse outcomes are observed in patients who required hospitalization and in adults. Recent studies indicate improved prognosis for cure and lower mortality rates than previously reported. However, the recovery can take several years and AN is associated with high risk of developing other psychiatric disorders during the patients' lifetime, even after recovery from AN (mainly: affective disorders, anxiety disorders, obsessive-compulsive disorders, substance abuse disorders). Studies indicate that bulimic symptoms often occur in the course of anorexia nervosa (especially within 2-3 years from the onset of AN). The authors present a review of literature on the course, comorbidity, mortality, and prognostic factors in AN. Better knowledge of the course of anorexia can contribute to more realistic expectations of the pace of symptomatic improvement, as well as to a creation of therapeutic programs which are better adapted to the needs of the patients.

    2000-07-01

    This paper addresses the lack of a standard protocol for pharmacotherapy trials for patients with bulimia nervosa (BN) and anorexia nervosa (AN). Twenty-two surveys were sent to established researchers in the field of eating disorders to elicit their opinions regarding medication trials, including baseline laboratory tests, the optimal length/frequency of medication management sessions, and the information that should or should not be included in these sessions. Sixteen of 22 researchers completed and returned the survey. Their answers are the basis of the data presented. We propose a battery of screening laboratory tests for both conditions. We suggest 30-45-min initial medication management sessions in both AN and BN trials with 15-min follow-ups to be held weekly for AN subjects, and weekly for 2 weeks, then biweekly for 2 weeks, then monthly, for BN subjects.

    Published studies suggested an implication of oxytocin in some temperament characteristics of personality. Therefore, we measured oxytocin secretion in 23 women with anorexia nervosa (AN), 27 with bulimia nervosa (BN) and 19 healthy controls and explored the relationships between circulating oxytocin and patients' personality traits. Plasma oxytocin levels were significantly reduced in AN women but not in BN ones. In healthy women, the attachment subscale scores of the reward dependence temperament and the harm avoidance (HA) scores explained 82% of the variability in circulating oxytocin. In BN patients, plasma oxytocin resulted to be negatively correlated with HA, whereas no significant correlations emerged in AN patients. These findings confirm a dysregulation of oxytocin production in AN but not in BN and show, for the first time, a disruption of the associations between hormone levels and patients' temperament traits, which may have a role in certain deranged behaviours of eating disorder patients.

    Interoceptive awareness is known to be impaired in eating disorders. To date, it has remained unclear whether this variable is related to the construct of interoceptive sensitivity. Interoceptive sensitivity is considered to be an essential variable in emotional processes. The objective of the study was to elucidate this potential relationship and to clarify whether general interoceptive sensitivity is reduced in anorexia nervosa. Using a heartbeat perception task, interoceptive sensitivity was assessed in 28 female patients with anorexia nervosa and 28 matched healthy controls. Questionnaires assessing interoceptive awareness (EDI) and several other variables were also administered. Patients with anorexia nervosa displayed significantly decreased interoceptive sensitivity. They also had more difficulties in interoceptive awareness. In addition to a decreased ability to recognize certain visceral sensations related to hunger, there is a generally reduced capacity to accurately perceive bodily signals in anorexia nervosa. This highlights the potential importance of interoceptive sensitivity in the pathogenesis of eating disorders.

  2. Altered social reward and attention in anorexia nervosa

    Full Text Available Dysfunctional social reward and social orienting attend a variety of neuropsychiatric disorders including autism, schizophrenia, social anxiety, and psychopathy. Here we show that similar social reward and attention dysfunction attend anorexia nervosa, a disorder defined by avoidance of food and extreme weight loss. We measured the implicit reward value of social stimuli for female participants with (n=11 and without (n=11 anorexia nervosa using an econometric choice task and also tracked gaze patterns during free viewing of images of female faces and bodies. As predicted, the reward value of viewing bodies varied inversely with observed body weight for women with anorexia but not neurotypical women, in contrast with their explicit ratings of attractiveness. Surprisingly, women with anorexia nervosa, unlike neurotypical women, did not find female faces rewarding and avoided looking at both the face and eyes—independent of observed body weight. These findings demonstrate comorbid dysfunction in the neural circuits mediating gustatory and social reward in anorexia nervosa.

  5. Comparing Wild American Grapes with Vitis vinifera: A Metabolomics Study of Grape Composition.

    Narduzzi, Luca; Stanstrup, Jan; Mattivi, Fulvio

    2015-08-05

    We analyzed via untargeted UHPLC-ESI-Q-TOF-MS the metabolome of the berry tissues (skin, pulp, seeds) of some American Vitis species (Vitis cinerea, Vitis californica, Vitis arizonica), together with four interspecific hybrids, and seven Vitis vinifera cultivars, aiming to find differences in the metabolomes of the American Vitis sp. versus Vitis vinifera. Apart from the known differences, that is, more complex content of anthocyanins and stilbenoids in the American grapes, we observed higher procyanidin accumulation (tens to hundreds of times) in the vinifera skin and seeds in comparison to American berries, and we confirmed this result via phloroglucinolysis. In the American grapes considered, we did not detect the accumulation of pleasing aroma precursors (terpenoids, glycosides), whereas they are common in vinifera grapes. We also found accumulation of hydrolyzable tannins and their precursors in the skin of the wild American grapes, which has never been reported earlier in any of the species under investigation. Such information is needed to improve the design of new breeding programs, lowering the risk of retaining undesirable characteristics in the chemical phenotype of the offspring.

  6. Antioxidant Effects of Grape Vine Cane Extracts from Different Chinese Grape Varieties on Edible Oils

    2014-09-01

    Full Text Available This study involved the determination of the peroxide value (POV as a measure of the resistance of the oxidation of edible oil with grape vine cane additives to assess their antioxidation potential. The study demonstrated that grape extracts of canes could effectively inhibit the lipid oxidation of edible oils and that this ability varied significantly due to the different extraction solvents employed, as well as to the different varieties of canes used. Lipid oxidation of edible oils was significantly reduced under an accelerated storage condition of 70 ± 1 °C in the presence of Vitamin C (VC, which was chosen as a synergist of grape vine cane extract. A 4:1 ratio of Victoria Blanc-ethyl acetate fraction (EAF and VC led to a significant lowering of the peroxide value and indicated a better antioxidant effect. Thus, these results indicated that some varieties of grape vine cane extracts could be applied as natural antioxidants for elevation of the quality of edible oils in the food industry.

    A bioelectronic tongue based on nanostructured biosensors specific for the simultaneous detection of sugars and phenols has been developed. The array combined oxidases and dehydrogenases immobilized on a lipidic layer prepared using the Langmuir-Blodgett technique where Glucose oxidase, D-Fructose dehydrogenase, Tyrosinase or Laccase were imbibed. A phthalocyanine was co-immobilized in the sensing layer and used as electron mediator. The array thus formed has been used to analyze grapes and provides global information about the samples while providing specific information about their phenolic and their sugar content. Using Principal Component Analysis (PCA) the array of voltammetric biosensors has been successfully used to discriminate musts prepared from different varieties of grapes (Tempranillo, Garnacha, Cabernet-Sauvignon, Prieto Picudo and Mencía). Differences could be also detected between grapes of the same variety and cultivar harvested in two successive vintages (2012 and 2013). Moreover, the ripening of grapes could be monitored from veraison to maturity due to the changes in their phenolic and sugar content. Using Partial Least Squares (PLS-1) analysis, excellent correlations have been found between the responses provided by the array of biosensors and classical parameters directly related to phenols (total polyphenol index, TPI) and sugar concentration (degree Brix) measured by chemical methods with correlation coefficients close to 1 and errors close to 0. It is also worthy to notice the good correlations found with parameters associated with the pH and acidity that can be explained by taking into account the influence of the pH in the oxidation potentials of the phenols and in the enzymatic activity. This bioelectronic tongue can assess simultaneously the sugar and the phenolic content of grapes and could be used to monitor the maturity of the fruit and could be adapted easily to field analysis. - Graphical abstract: A bioelectronic tongue based on

  10. Could Dopamine Agonists Aid in Drug Development for Anorexia Nervosa?

    Frank, Guido K. W.

    2014-01-01

    Anorexia nervosa is a severe psychiatric disorder most commonly starting during the teenage-years and associated with food refusal and low body weight. Typically there is a loss of menses, intense fear of gaining weight, and an often delusional quality of altered body perception. Anorexia nervosa is also associated with a pattern of high cognitive rigidity, which may contribute to treatment resistance and relapse. The complex interplay of state and trait biological, psychological, and social factors has complicated identifying neurobiological mechanisms that contribute to the illness. The dopamine D1 and D2 neurotransmitter receptors are involved in motivational aspects of food approach, fear extinction, and cognitive flexibility. They could therefore be important targets to improve core and associated behaviors in anorexia nervosa. Treatment with dopamine antagonists has shown little benefit, and it is possible that antagonists over time increase an already hypersensitive dopamine pathway activity in anorexia nervosa. On the contrary, application of dopamine receptor agonists could reduce circuit responsiveness, facilitate fear extinction, and improve cognitive flexibility in anorexia nervosa, as they may be particularly effective during underweight and low gonadal hormone states. This article provides evidence that the dopamine receptor system could be a key factor in the pathophysiology of anorexia nervosa and dopamine agonists could be helpful in reducing core symptoms of the disorder. This review is a theoretical approach that primarily focuses on dopamine receptor function as this system has been mechanistically better described than other neurotransmitters that are altered in anorexia nervosa. However, those proposed dopamine mechanisms in anorexia nervosa also warrant further study with respect to their interaction with other neurotransmitter systems, such as serotonin pathways.

    2010-12-01

    Full Text Available Anthocyanins, synthesized via the flavonoid pathway, are a class of crucial phenolic compounds which are fundamentally responsible for the red color of grapes and wines. As the most important natural colorants in grapes and their products, anthocyanins are also widely studied for their numerous beneficial effects on human health. In recent years, the biosynthetic pathway of anthocyanins in grapes has been thoroughly investigated. Their intracellular transportation and accumulation have also been further clarified. Additionally, the genetic mechanism regulating their biosynthesis and the phytohormone influences on them are better understood. Furthermore, due to their importance in the quality of wine grapes, the effects of the environmental factors and viticulture practices on anthocyanin accumulation are being investigated increasingly. The present paper summarizes both the basic information and the most recent advances in the study of the anthocyanin biosynthesis in red grapes, emphasizing their gene structure, the transcriptional factors and the diverse exterior regulation factors.

    Plant protection based on novel alternative strategies is a major concern in agriculture to sustain pest management. The marc extract of red grape cultivars reveals plant defence inducer properties. Treatment with grape marc extract efficiently induced hypersensitive reaction-like lesions with cell death evidenced by Evans Blue staining of tobacco leaves. Examination of the infiltration zone and the surrounding areas under UV light revealed the accumulation of autofluorescent compounds. Both leaf infiltration and a foliar spray of the red grape extract on tobacco leaves induced defence gene expression. The PR1 and PR2 target genes were upregulated locally and systemically in tobacco plants following grape marc extract treatment. The grape extract elicited an array of plant defence responses making this natural compound a potential phytosanitary product with a challenging issue and a rather attractive option for sustainable agriculture and environmentally friendly practices.

    To determine the levels of interoceptive awareness (IA), which measures the ability of an individual to discriminate between sensations and feelings, and between the sensations of hunger and satiety, in eating disorder patients and to identify the clinical, psychopathological and personal variables correlated with IA. Sixty-one restrictor anorectics, 61 binge-purging anorectics, 104 purging bulimics, 49 obese subjects with binge eating disorder (BED) and 47 obese subjects without BED were compared. They were assessed with the Eating Disorder Inventory-2, the Temperament and Character Inventory, and the Beck Depression Inventory, and their clinical and sociodemographic features were recorded. In all patients, the levels of IA were higher than the 'normal' ones; in bulimia nervosa, they were higher than in anorexia nervosa and obesity. Similar personal features and eating attitudes are shared by patients with bulimia nervosa and BED. In the total sample, the following variables independently correlate with IA: the Beck Depression Inventory, self- directedness and persistence. The importance of an altered IA in eating disorders is supported. Both depression and a perfectionist and poorly self-directive personality can lead to greater difficulties in discriminating hunger and satiety. Copyright 2004 S. Karger AG, Basel

    A history of anorexia nervosa has been associated with a reduced risk of developing breast cancer. We investigated survival after breast cancer among women with a prior anorexia nervosa diagnosis compared with women in a population comparison group. This register-based study included combined data from Sweden, Denmark and Finland. A total of 76 and 1462 breast cancer cases identified among 22,654 women with anorexia nervosa and 224,619 women in a population comparison group, respectively, were included in the study. Hazard ratios (HR) for overall and breast cancer-specific mortality after breast cancer diagnosis were estimated using Cox regression. Cause of death was available only for Swedish and Danish women; therefore, the analysis on breast cancer-specific mortality was restricted to these women. We observed 23 deaths after breast cancer among anorexia nervosa patients and 247 among population comparisons. The overall mortality after the breast cancer diagnosis was increased in women with a history of anorexia nervosa compared with population comparisons (HR 2.5, 95% CI 1.6-3.9) after adjustment for age, period and extent of disease. Results were similar for overall (HR 2.3, 95% CI 1.4-3.6) and breast cancer-specific mortality (HR 2.1, 95% CI 1.3-3.6) among Swedish and Danish women. We found that female breast cancer patients with a prior diagnosis of anorexia nervosa have a worse survival compared with other breast cancer patients.

    Full Text Available Social cognition represents the mental processes of social interaction between oneself and others. In recent years, the interest in social cognition skills has increased in cases with eating disorders. Anorexia nervosa is an eating disorder that is associated with the multiple factors in etiology. Treatment of anorexia nervosa is still controversial. The youths diagnosed with anorexia nervosa are known to be as the most difficult group in eating disorders for building therapeutic relations. Studies, mostly suggests that there are difficulties in social cognitive functions in patients with anorexia nervosa. However, there are studies that reported different results. It seems that, the majority of studies which evaluate the social cognitive functions in patients with anorexia nervosa, are carried out with the adult age group. There are limited number of studies in child and adolescent age group. The purpose of this paper was to examinate the studies of social cognitive skills in children and adolescents diagnosed with anorexia nervosa and present the general characteristics.

    Anorexia nervosa is a common psychiatric disorder in adolescence and is related to cardiovascular complications. Our aim was to study the effect of anorexia nervosa on metabolic parameters, leucocyte-endothelium interactions, adhesion molecules and proinflammatory cytokines. This multicentre, cross-sectional, case-control study employed a population of 24 anorexic female patients and 36 controls. We evaluated anthropometric and metabolic parameters, interactions between leucocytes polymorphonuclear neutrophils (PMN) and human umbilical vein endothelial cells (HUVEC), proinflammatory cytokines such as tumour necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) and soluble cellular adhesion molecules (CAMs) including E-selectin, vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1). Anorexia nervosa was related to a decrease in weight, body mass index, waist circumference, systolic blood pressure, glucose, insulin and HOMA-IR, and an increase in HDL cholesterol. These effects disappeared after adjusting for BMI. Anorexia nervosa induced a decrease in PMN rolling velocity and an increase in PMN rolling flux and PMN adhesion. Increases in IL-6 and TNF-α and adhesion molecule VCAM-1 were also observed. This study supports the hypothesis of an association between anorexia nervosa, inflammation and the induction of leucocyte-endothelium interactions. These findings may explain, in part at least, the increased risk of vascular disease among patients with anorexia nervosa. © 2015 Stichting European Society for Clinical Investigation Journal Foundation.

    The grape is one of the earliest domesticated fruit crops and, since antiquity, it has been widely cultivated and prized for its fruit and wine. Here, we characterize genome-wide patterns of genetic variation in over 1,000 samples of the domesticated grape, Vitis vinifera subsp. vinifera, and its wild relative, V. vinifera subsp. sylvestris from the US Department of Agriculture grape germplasm collection. We find support for a Near East origin of vinifera and present evidence of introgression from local sylvestris as the grape moved into Europe. High levels of genetic diversity and rapid linkage disequilibrium (LD) decay have been maintained in vinifera, which is consistent with a weak domestication bottleneck followed by thousands of years of widespread vegetative propagation. The considerable genetic diversity within vinifera, however, is contained within a complex network of close pedigree relationships that has been generated by crosses among elite cultivars. We show that first-degree relationships are rare between wine and table grapes and among grapes from geographically distant regions. Our results suggest that although substantial genetic diversity has been maintained in the grape subsequent to domestication, there has been a limited exploration of this diversity. We propose that the adoption of vegetative propagation was a double-edged sword: Although it provided a benefit by ensuring true breeding cultivars, it also discouraged the generation of unique cultivars through crosses. The grape currently faces severe pathogen pressures, and the long-term sustainability of the grape and wine industries will rely on the exploitation of the grape's tremendous natural genetic diversity.

    2013-09-01

    Full Text Available The aim of this work is to evaluate the sustainability, in terms of greenhouse gases emission saving, of a new potential bio-ethanol production chain in comparison with the most common ones. The innovation consists of producing bio-ethanol from different types of no-food grapes, while usually bio-ethanol is obtained from matrices taken away from crop for food destination: sugar cane, corn, wheat, sugar beet. In the past, breeding programs were conducted with the aim of improving grapevine characteristics, a large number of hybrid vine varieties were produced and are nowadays present in the CRA-VIT (Viticulture Research Centre Germplasm Collection. Some of them are potentially interesting for bio-energy production because of their high production of sugar, good resistance to diseases, and ability to grow in marginal lands. LCA (Life Cycle Assessment of grape ethanol energy chain was performed following two different methods: (i using the spreadsheet “BioGrace, developed within the “Intelligent Energy Europe” program to support and to ease the RED (Directive 2009/28/EC implementation; (ii using a dedicated LCA software. Emissions were expressed in CO2 equivalent (CO2eq. The results showed that the sustainability limits provided by the normative are respected to this day. On the contrary, from 2017 this production will be sustainable only if the transformation processes will be performed using renewable sources of energy. The comparison with other bioenergy chains points out that the production of ethanol using grapes represents an intermediate situation in terms of general emissions among the different production chains.

    DIG, a liquid herbal preparation made from a mixture of diluted mother tinctures of Berberis vulgaris, Taraxacum officinale and Arctium lappa, was assessed for its antimutagenic properties against mitomycin C. The micronucleus assay on Chinese hamster ovary (CHO)-K1 cells was used to evaluate the in vitro anticlastogenic activity of DIG compared to those of separately diluted mother tinctures. The micronucleus assay was performed on mouse erythrocytes and the comet assay was performed on mouse liver, kidney, lung, brain and testicles to assess the protective effects of DIG (0.2 and 2 % at libitum) against an intraperitoneal injection of mitomycin C (1 mg Kg(-1)) in mice. DIG exerted a powerful anticlastogenic activity, under both pretreatment and simultaneous treatment conditions as assessed by the micronucleus assay in CHO-K1 cells. Its protective activity was greater than that observed for each mother tincture. DIG reduced micronuclei levels in mouse erythrocytes and suppressed >80 % of DNA strand breaks in the liver, kidney, lung, brain and testicles of mice exposed to mitomycin C.

    Invasive terrestrial plants often substantially reshape environments, yet how such invasions affect terrestrial snail assemblages remains understudied. We investigated how snail assemblages in deciduous forest soils with dense Berberis thunbergii (Japanese barberry), an invasive shrub in eastern North America, differ from forest areas lacking the shrub. Leaf litter and soil samples were collected from forest patches with dense B. thunbergii understories and adjacent control areas within two exurban forest tracts in western Pennsylvania, U.S.A. Snails were identified to species and quantified by standard diversity metrics. Contrary to our expectations, snails were significantly more abundant and diverse in B. thunbergii-invaded areas. Despite differences in abundance, the snail community composition did not differ between invaded and control habitats. The terrestrial snail assemblage we observed, which was composed entirely of native species, appears to respond favorably to B. thunbergii invasion and therefore may not be negatively impacted by physicochemical changes to soils typically observed in association with the plant. Such findings could reflect the fact that B. thunbergii likely creates more favorable habitat for snails by creating cooler, more humid, and more alkaline soil environments. However, the snail assemblages we retrieved may consist mostly of species with high tolerance to environmental degradation due to a legacy of land use change and acid deposition in the region.

    The identification of archaeological charred grape seeds is a difficult task due to the alteration of the morphological seeds shape. In archaeobotanical studies, for the correct discrimination between Vitis vinifera subsp. sylvestris and Vitis vinifera subsp. vinifera grape seeds it is very important to understand the history and origin of the domesticated grapevine. In this work, different carbonisation experiments were carried out using a hearth to reproduce the same burning conditions that occurred in archaeological contexts. In addition, several carbonisation trials on modern wild and cultivated grape seeds were performed using a muffle furnace. For comparison with archaeological materials, modern grape seed samples were obtained using seven different temperatures of carbonisation ranging between 180 and 340ºC for 120 min. Analysing the grape seed size and shape by computer vision techniques, and applying the stepwise linear discriminant analysis (LDA) method, discrimination of the wild from the cultivated charred grape seeds was possible. An overall correct classification of 93.3% was achieved. Applying the same statistical procedure to compare modern charred with archaeological grape seeds, found in Sardinia and dating back to the Early Bronze Age (2017–1751 2σ cal. BC), allowed 75.0% of the cases to be identified as wild grape. The proposed method proved to be a useful and effective procedure in identifying, with high accuracy, the charred grape seeds found in archaeological sites. Moreover, it may be considered valid support for advances in the knowledge and comprehension of viticulture adoption and the grape domestication process. The same methodology may also be successful when applied to other plant remains, and provide important information about the history of domesticated plants. PMID:26901361

  11. Procyanidin content of grape seed and pomace, and total anthocyanin content of grape pomace as affected by extrusion processing.

    Khanal, R C; Howard, L R; Prior, R L

    2009-08-01

    Grape juice processing by-products, grape seed and pomace are a rich source of procyanidins, compounds that may afford protection against chronic disease. This study was undertaken to identify optimal extrusion conditions to enhance the contents of monomers and dimers at the expense of large molecular weight procyanidin oligomers and polymers in grape seed and pomace. Extrusion variables, temperature (160, 170, and 180 degrees C in grape seed, and 160, 170, 180, and 190 degrees C in pomace) and screw speed (100, 150, and 200 rpm in both) were tested using mixtures of grape seed as well as pomace with decorticated white sorghum flour at a ratio of 30 : 70 and moisture content of 45%. Samples of grape seed and pomace were analyzed for procyanidin composition before and after extrusion, and total anthocyanins were determined in pomace. Additionally, chromatograms from diol and normal phase high-performance liquid chromatography were compared for the separation of procyanidins. Extrusion of both grape by-products increased the biologically important monomer and dimers considerably across all temperature and screw speeds. Highest monomer content resulted when extruded at a temperature of 170 degrees C and screw speed of 200 rpm, which were 120% and 80% higher than the unextruded grape seed and pomace, respectively. Increases in monomer and dimer contents were apparently the result of reduced polymer contents, which declined by 27% to 54%, or enhanced extraction facilitated by disruption of the food matrix during extrusion. Extrusion processing reduced total anthocyanins in pomace by 18% to 53%. Extrusion processing can be used to increase procyanidin monomer and dimer contents in grape seed and pomace. Procyanidins in grape by-products have many health benefits, but most are present as large molecular weight compounds, which are poorly absorbed. Extrusion processing appears to be a promising technology to increase levels of the bioactive low molecular weight

  12. Delirium and refeeding syndrome in anorexia nervosa.

    2012-04-01

    To review the literature on delirium and refeeding syndrome in patients with anorexia nervosa (AN) and present case examples in an attempt to identify common clinical features and response to therapy. A comprehensive literature review was completed. In addition to the cases identified in the literature, we present two additional cases of our own. We identified a total of 10 cases (all female; mean age 19 years old, range 12-29 years); 2/3 of the cases had similar clinical features predating the delirium and during refeeding. Delirium, albeit rare, can be associated with the refeeding syndrome in low weight patients with AN. During the initial refeeding phase, close monitoring of medical, metabolic, and psychological parameters are important in establishing factors that may elevate risk. Early detection and treatment of delirium using nonpharmacologic and pharmacologic means are also important to help minimize the effects of this potentially deadly condition.

  13. [Termination of inpatient treatment for anorexia nervosa].

    Zeeck, A; Herzog, T

    2000-07-01

    Dropout is a neglected area of research; patients with anorexia nervosa are a group with high risk for dropout. 1. What are the frequency and type of dropout in disorder-specific, integrated treatment programs for anorexic patients? 2. What are the predictors for dropout? Analysis of 80 prospectively documented, consecutive treatment episodes of anorexic inpatients, based on multimodal clinical and psychometric parameters. Twenty percent of patients terminated on their own initiative, often after reaching target weight; 10% were discharged by the treatment team. At least 43% of dropouts continued with some sort of psychotherapy within the 3 months after discharge. Previous dropout was a predictor for dropout in the present episodes. Patients with no comorbidity had a higher risk of dropout. Patients discharged by the team had personality disorders more often. Patients with comorbid depression stayed in treatment. The form of termination of treatment should be routinely assessed. Previous dropout and comorbidity are indicators of the risk of dropout.

  14. Symptoms predicting psychosocial impairment in bulimia nervosa.

    Jenkins, Paul E; Staniford, Jessica; Luck, Amy

    2017-05-12

    The current study aimed to determine which particular eating disorder (ED) symptoms and related features, such as BMI and psychological distress, uniquely predict impairment in bulimia nervosa (BN). Two hundred and twenty-two adults with BN completed questionnaires assessing ED symptoms, general psychological distress, and psychosocial impairment. Regression analyses were used to determine predictors which account for variance in impairment. Four variables emerged as significant predictors of psychosocial impairment: concerns with eating; concerns with weight and shape; dietary restraint; and general psychological distress. Findings support previous work highlighting the importance of weight and shape concerns in determining ED-related impairment. Other ED symptoms, notably dietary restraint and concerns with eating, were also significant predictors as was psychological distress. Results suggest that cognitive aspects of EDs, in addition to psychological distress, may be more important determinants of impairment than behavioural symptoms, such as binge eating or purging.

  15. Extreme Achalasia Presenting as Anorexia Nervosa

    2012-01-01

    Full Text Available Background. Achalasia may lead to cachexia if not diagnosed in an early stage. Surgery in cachectic patients is hazardous and complications may result in a protracted recovery or even death. Different treatment options have been described. In this paper, we report a stepwise surgical laparoscopic approach which appears to be safe and effective. Methods. Over a one-year period, a patient with a body mass index (BMI below 17 being treated for anorexia nervosa was referred with dysphagia. Because of the extreme cachexia, a laparoscopic feeding jejunostomy (LFJ was fashioned to enable long-term home enteral feeding. The patient underwent a laparoscopic Heller myotomy (LHM when the BMI was normal. Results. The patient recovered well following this stepwise approach. Conclusion. Patients with advanced achalasia usually present with extreme weight loss. In this small group of patients, a period of home enteral nutrition (HEN via a laparoscopically placed feeding jejunostomy allows weight gain prior to safe definitive surgery.

  16. Orthorexia Nervosa: A Review of the Literature.

    Costa, Christine B; Hardan-Khalil, Kholoud; Gibbs, Kimberly

    2017-12-01

    The phenomenon of orthorexia nervosa (ON) has been noted by clinicians since 1996 and described in the scientific literature, and yet there is no formal recognition of ON as a psychiatric diagnosis. Review the latest available literature regarding diagnoses similarities, presentation uniqueness, assessment/assessment tools, and suggested treatments of ON. A literature search of four databases focusing on articles published between 2000 and 2016 was conducted to evaluate the status of the literature on Orthorexia. Among the 15 articles selected for this review, similarities with other psychiatric disorders emerged, confusion about use of assessment tools existed, and the lack of evidence based treatments for ON was pronounced. More research is needed to determine the prevalence of pathologically unhealthy, obsessive, "self-defined healthy," eating behaviors, and to determine if ON is a unique eating disorder or just a subset of another disorder.

  17. [Orthorexia nervosa and it's background factors].

    Varga, Márta; Dukay-Szabo, Szilvia; Túry, Ferenc

    2013-07-30

    The place of orthorexia nervosa (ON)--described by Bratman in 1997--is not clearly defined in the diagnostic systems. However, the increasing number of clinical experiences and research data gives us more and more information about the epidemiology, and the social and individual characteristics of ON. The general population shows a 6.9% prevalence of ON; healthcare professionals are at high risk of ON with the prevalence rate of 35-57.6%. Education, the choice of profession, socioeconomic status and the internalization of the ideals of society are significant factors in the development of ON, while sex, age and body mass index do not seem to be determining variables in this respect. The lack of common criteria and proper research results on ON makes it impossible to generalize data on the general population. Further studies with larger representative samples and assessment instruments with good psychometric properties are necessary to make research data on ON comparable.

  18. Siblings in the context of anorexia nervosa.

    Bachner-Melman, Rachel

    2005-01-01

    Sibling relationships may be relevant to the development of anorexia nervosa (AN), yet little research has focused on this aspect of the disorder. A narrative study of four women in various stages of recovery from AN is described and results relevant to sibling relationships are presented, enriched by published anecdotes and case studies. The anorexic interviewees described much antagonism and rivalry and little warmth and intimacy between themselves and their siblings. They seemed to feel they did not belong sufficiently in their families and other social settings despite a strong desire to belong. The sample is small, reports subjective and retrospective and no control group was included. It is suggested that anorexic girls often feel emotionally isolated from and misunderstood by siblings, who may have much to contribute to the process of therapy and recovery.

    2010-02-01

    We report here the first integrated investigation of both ancient DNA and proteins in archaeobotanical samples: medieval grape ( Vitis vinifera L.) seeds, preserved by anoxic waterlogging, from an early medieval (seventh-eighth century A.D.) Byzantine rural settlement in the Salento area (Lecce, Italy) and a late (fourteenth-fifteenth century A.D.) medieval site in York (England). Pyrolysis gas chromatography mass spectrometry documented good carbohydrate preservation, whilst amino acid analysis revealed approximately 90% loss of the original protein content. In the York sample, mass spectrometry-based sequencing identified several degraded ancient peptides. Nuclear microsatellite locus (VVS2, VVMD5, VVMD7, ZAG62 and ZAG79) analysis permitted a tentative comparison of the genetic profiles of both the ancient samples with the modern varieties. The ability to recover microsatellite DNA has potential to improve biomolecular analysis on ancient grape seeds from archaeological contexts. Although the investigation of five microsatellite loci cannot assign the ancient samples to any geographic region or modern cultivar, the results allow speculation that the material from York was not grown locally, whilst the remains from Supersano could represent a trace of contacts with the eastern Mediterranean.

  20. Control of Ochratoxin A Production in Grapes

    Sofía Chulze

    2012-05-01

    Full Text Available Ochratoxin A (OTA is a mycotoxin commonly present in cereals, grapes, coffee, spices, and cocoa. Even though the main objective of the food and feed chain processors and distributors is to avoid the extended contamination of plant-derived foods and animal feeds with mycotoxins, until now, complete OTA removal from foods and feedstuffs is not feasible. Prevention through pre-harvest management is the best method for controlling mycotoxin contamination. However, in the case that the contamination occurs after this stage, the hazards associated with OTA must be managed through post-harvest strategies. Due to the increasing number of fungal strains resistant to chemical fungicides and the impact of these pesticides on the environment and human health, maximum levels of chemical residues have been regulated in many products. Alternative methods are necessary to substitute or complement treatments with fungicides to control fungi under field or storage conditions. Yeasts are considered one of the most potent biocontrol agents due to their biology and non-toxic properties. Epiphytic yeasts are the major component of the microbial community on the surface of grape berries and they are evolutionarily adapted to this ecological niche. Nowadays, several yeast species included in different genera are considered as potential biocontrol agents to control both, growth of ochratoxigenic Aspergillus species and OTA accumulation.

  1. Medical Complications In Anorexia And Bulimia Nervosa.

    Gravina, Giovanni; Milano, Walter; Nebbiai, Grazia; Piccione, Carla; Capasso, Anna

    2018-05-30

    Anorexia Nervosa (AN), Bulimia Nervosa (BN) and their variants are characterized by persistent alteration of eating behaviour, such as restricted intake or bingeing and purging, as well as excessive concerns about body shape and body weight. Purging behaviour may include self induced vomiting and/or abuse of laxatives, diuretics and physical hyperactivity. Unlike other psychiatric disorders, patients suffering from AN and BN have a high prevalence of many different medical complications, through the sequelae of undernutrition and purging, often with a serious impairment of health status and quality of life. This article describes the main diagnostic and clinical aspects of medical complications in AN and BN. The medical complications of ED are extremely variable and can occur with only modest biological and physical damage up to extremely serious and life-threatening conditions; the mortality rate of young subjects with AN is 4 - 11% with a risk of death about 12 times higher than that of subjects of the same age of the general population. The management of the medical-internship aspects of AN and BN is rightly placed within complex and articulated programs of interdisciplinary treatment with different levels of intensity of care (outpatient, semi-residential/residential, hospital in cases of emergency/medical and/or psychiatric emergency). the results of the investigations carried out, describe the functions of the various organs and apparatuses and the alterations detected, the possible complications and physiological adaptations to malnutrition.

  2. Effects of soil characteristics on grape juice nutrient concentrations and other grape quality parameters in Shiraz

    Concepción Ramos, Maria; Romero, Maria Paz

    2017-04-01

    This study investigated the response of grapes to soil properties in the variety Shiraz (SH) cultivated in the Costers de Segre Designation of Origin (NE, Spain). The research was carried out in two areas with differences in vigor, which was examined using the Normalized Difference Vegetation Index (NDVI). Soil properties such as organic matter content, pH, electrical conductivity and nutrients (N, P, K, Ca, Mg, Cu, Zn and Mn) were analysed in the two areas. Soil analyses were limited to the upper 40 cm. Soil N-NO3 was measured in 2M KCl extracts. Assimilable phosphorus was analysed by extraction with 0.5 M NaHCO3 at pH 8.5 using the Olsen method. The available K, Ca and Mg were evaluated in hemaaxinecobalt trichloride extracts and the available fraction of Cu, Zn, Mn and Fe in DTPA- trietanolamine extracts, by spectroscopy atomic emission/absorption. Berry grapes were collected at maturity. Nutrients in grape juice (K, Ca, Mg Cu, Zn, Mn and Fe) were determined after a microwave hydrogen peroxide digestion in a closed vessel microwave digestion system and measured by spectroscopy. Other grape properties that determine grape quality such as pH, berry weight and sugar content were analysed using the methods proposed by the OIV. Differences in soil properties were observed between plots, which determined the differences in vigour. The vines with lower vigour were grown in the soils with higher pH, electrical conductivity and silt content, which had in addition higher Ca, Mg and K available levels as well as higher levels of Fe and Mn than the soil in which vines had higher vigour. However, the available fraction of Cu and Zn was smaller. Similar differences in nutrient concentration in the berry were observed for all nutrients except for Cu. Grape juice pH and total soluble solids (°Brix) were higher in the most vigorous vines. However, the differences in berry weight and total acidity at ripening were not significant.

  5. Genealogy of wine grape cultivars: "Pinot" is related to "Syrah".

    Vouillamoz, J F; Grando, M S

    2006-08-01

    Since the domestication of wild grapes ca 6000 years ago, numerous cultivars have been generated by spontaneous or deliberate crosses, and up to 10 000 are still in existence today. Just as in human paternity analysis, DNA typing can reveal unexpected parentage of grape cultivars. In this study, we have analysed 89 grape cultivars with 60 microsatellite markers in order to accurately calculate the identity-by-descent (IBD) and relatedness (r) coefficients among six putatively related cultivars from France ("Pinot", "Syrah" and "Dureza") and northern Italy ("Teroldego", "Lagrein" and "Marzemino"). Using a recently developed likelihood-based approach to analyse kinship in grapes, we provide the first evidence of a genetic link between grapes across the Alps: "Dureza" and "Teroldego" turn out to be full-siblings (FS). For the first time in grapevine genetics we were able to detect FS without knowing one of the parents and identify unexpected second-degree relatives. We reconstructed the most likely pedigree that revealed a third-degree relationship between the worldwide-cultivated "Pinot" from Burgundy and "Syrah" from the Rhone Valley. Our finding was totally unsuspected by classical ampelography and it challenges the commonly assumed independent origins of these grape cultivars. Our results and this new approach in grape genetics will (a) help grape breeders to avoid choosing closely related varieties for new crosses, (b) provide pedigrees of cultivars in order to detect inheritance of disease-resistance genes and (c) open the way for future discoveries of first- and second-degree relationships between grape cultivars in order to better understand viticultural migrations.

    Having more information on the yeast ecology of grapes is important for wine-makers to produce wine with high quality and typical attributes. China is a significant wine-consuming country and is becoming a serious wine-producer, but little has been reported about the yeast ecology of local ecosystems. This study provides the first step towards the exploitation of the yeast wealth in China's vine-growing regions. The aim of this study was to investigate the yeast population density and diversity on three grape varieties cultivated in four representative vine-growing regions of China. Yeast species diversity was evaluated by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequence analysis of the 5.8S internal transcribed spacer (ITS) ribosomal DNA (rDNA) region of cultivable yeasts. The grapes harbored yeast populations at 10(2)-10(6)CFU/mL, consisting mostly of non-Saccharomyces species. Seventeen different yeast species belonging to eight genera were detected on the grape samples tested, including Hanseniaspora uvarum, Cryptococcus flavescens, Pichia fermentans, Candida zemplinina, Cryptococcus carnescens, Candida inconpicua, Zygosaccharomyces fermentati, Issatchenkia terricola, Candida quercitrusa, Hanseniaspora guilliermondii, Candida bombi, Zygosaccharomyces bailii, Sporidiobolus pararoseus, Cryptococcus magnus, Metschnikowia pulcherrima, Issatchenkia orientalis and Pichia guilliermondii. H. uvarum and C. flavescens were the dominant species present on the grapes. For the first time Sporidiobolus pararoseus was discovered as an inhabitant of the grape ecosystem. The yeast community on grape berries was influenced by the grape chemical composition, vine-variety and vine-growing region. This study is the first to identify the yeast communities associated with grapes in China using molecular methods. The results enrich our knowledge of wine-related microorganisms, and can be used to promote the development of the local wine

    Objective The purpose of this investigation was to examine differences in personality dimensions among individuals with bulimia nervosa, binge eating disorder, non-binge eating obesity and a normal weight comparison group as well as to determine the extent to which these differences were independent of self-reported depressive symptoms. Method Personality dimensions were assessed using the Multidimensional Personality Questionnaire in 36 patients with bulimia nervosa, 54 patients with binge eating disorder, 30 obese individuals who did not binge eat, and 77 normal weight comparison participants. Results Participants with bulimia nervosa reported higher scores on measures of stress reaction and negative emotionality compared to the other three groups, and lower well-being scores compared to the normal weight comparison and the obese samples. Patients with binge eating disorder scored lower on well-being and higher on harm avoidance than the normal weight comparison group. In addition, the bulimia nervosa and binge eating disorder groups scored lower than the normal weight group on positive emotionality. When personality dimensions were re-analyzed using depression as a covariate, only stress reaction remained higher in the bulimia nervosa group compared to the other three groups and harm avoidance remained higher in the binge eating disorder than the normal weight comparison group. Conclusions The higher levels of stress reaction in the bulimia nervosa sample and harm avoidance in the binge eating disorder sample after controlling for depression indicate that these personality dimensions are potentially important in the etiology, maintenance, and treatment of these eating disorders. Although the extent to which observed group differences in well-being, positive emotionality and negative emotionality reflect personality traits, mood disorders, or both is unclear, these features clearly warrant further examination in understanding and treating bulimia nervosa and

    Purpose To determine indexes of skeletal integrity by using computed tomographic (CT) trabecular texture analysis of the lumbar spine in patients with anorexia nervosa and normal-weight control subjects and to determine body composition predictors of trabecular texture. Materials and Methods This cross-sectional study was approved by the institutional review board and compliant with HIPAA. Written informed consent was obtained. The study included 30 women with anorexia nervosa (mean age ± standard deviation, 26 years ± 6) and 30 normal-weight age-matched women (control group). All participants underwent low-dose single-section quantitative CT of the L4 vertebral body with use of a calibration phantom. Trabecular texture analysis was performed by using software. Skewness (asymmetry of gray-level pixel distribution), kurtosis (pointiness of pixel distribution), entropy (inhomogeneity of pixel distribution), and mean value of positive pixels (MPP) were assessed. Bone mineral density and abdominal fat and paraspinal muscle areas were quantified with quantitative CT. Women with anorexia nervosa and normal-weight control subjects were compared by using the Student t test. Linear regression analyses were performed to determine associations between trabecular texture and body composition. Results Women with anorexia nervosa had higher skewness and kurtosis, lower MPP (P anorexia nervosa. Conclusion Patients with anorexia nervosa had increased skewness and kurtosis and decreased entropy and MPP compared with normal-weight control subjects. These parameters were associated with lowest lifetime weight and duration of amenorrhea, but there were no such associations with bone mineral density. These findings suggest that trabecular texture analysis might contribute information about bone health in anorexia nervosa that is independent of that provided with bone mineral density. © RSNA, 2016.

  9. Neural signature of behavioural inhibition in women with bulimia nervosa.

    Impaired inhibitory control is considered a behavioural phenotype in patients with bulimia nervosa. However, the underlying neural correlates of impaired general and food-specific behavioural inhibition are largely unknown. Therefore, we investigated brain activation during the performance of behavioural inhibition to general and food-related stimuli in adults with bulimia nervosa. Women with bulimia and healthy control women underwent event-related fMRI while performing a general and a food-specific no-go task. We included 28 women with bulimia nervosa and 29 healthy control women in our study. On a neuronal level, we observed significant group differences in response to general no-go stimuli in women with bulimia nervosa with high symptom severity; compared with healthy controls, the patients showed reduced activation in the right sensorimotor area (postcentral gyrus, precentral gyrus) and right dorsal striatum (caudate nucleus, putamen). The present results are limited to adult women with bulimia nervosa. Furthermore, it remains unclear whether impaired behavioural inhibition in patients with this disorder are a cause or consequence of chronic illness. Our findings suggest that diminished frontostriatal brain activation in patients with bulimia nervosa contribute to the severity of binge eating symptoms. Gaining further insight into the neural mechanisms of behavioural inhibition problems in individuals with this disorder may inform brain-directed treatment approaches and the development of response inhibition training approaches to improve inhibitory control in patients with bulimia nervosa. The present study does not support greater behavioural and neural impairments to food-specific behavioural inhibition in these patients.

    Background Impaired inhibitory control is considered a behavioural phenotype in patients with bulimia nervosa. However, the underlying neural correlates of impaired general and food-specific behavioural inhibition are largely unknown. Therefore, we investigated brain activation during the performance of behavioural inhibition to general and food-related stimuli in adults with bulimia nervosa. Methods Women with bulimia and healthy control women underwent event-related fMRI while performing a general and a food-specific no-go task. Results We included 28 women with bulimia nervosa and 29 healthy control women in our study. On a neuronal level, we observed significant group differences in response to general no-go stimuli in women with bulimia nervosa with high symptom severity; compared with healthy controls, the patients showed reduced activation in the right sensorimotor area (postcentral gyrus, precentral gyrus) and right dorsal striatum (caudate nucleus, putamen). Limitations The present results are limited to adult women with bulimia nervosa. Furthermore, it remains unclear whether impaired behavioural inhibition in patients with this disorder are a cause or consequence of chronic illness. Conclusion Our findings suggest that diminished frontostriatal brain activation in patients with bulimia nervosa contribute to the severity of binge eating symptoms. Gaining further insight into the neural mechanisms of behavioural inhibition problems in individuals with this disorder may inform brain-directed treatment approaches and the development of response inhibition training approaches to improve inhibitory control in patients with bulimia nervosa. The present study does not support greater behavioural and neural impairments to food-specific behavioural inhibition in these patients. PMID:27575858

    The purpose of this investigation was to examine differences in personality dimensions among individuals with bulimia nervosa, binge eating disorder, non-binge eating obesity, and a normal-weight comparison group as well as to determine the extent to which these differences were independent of self-reported depressive symptoms. Personality dimensions were assessed using the Multidimensional Personality Questionnaire in 36 patients with bulimia nervosa, 54 patients with binge eating disorder, 30 obese individuals who did not binge eat, and 77 normal-weight comparison participants. Participants with bulimia nervosa reported higher scores on measures of stress reaction and negative emotionality compared to the other 3 groups and lower well-being scores compared to the normal-weight comparison and the obese samples. Patients with binge eating disorder scored lower on well-being and higher on harm avoidance than the normal-weight comparison group. In addition, the bulimia nervosa and binge eating disorder groups scored lower than the normal-weight group on positive emotionality. When personality dimensions were reanalyzed using depression as a covariate, only stress reaction remained higher in the bulimia nervosa group compared to the other 3 groups and harm avoidance remained higher in the binge eating disorder than the normal-weight comparison group. The higher levels of stress reaction in the bulimia nervosa sample and harm avoidance in the binge eating disorder sample after controlling for depression indicate that these personality dimensions are potentially important in the etiology, maintenance, and treatment of these eating disorders. Although the extent to which observed group differences in well-being, positive emotionality, and negative emotionality reflect personality traits, mood disorders, or both, is unclear, these features clearly warrant further examination in understanding and treating bulimia nervosa and binge eating disorder.

    Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) may exhibit reduced ability to modulate sensory, physiological, and affective responses. The aim of the present study is to assess sensory modulation disorder (SMD) symptoms in patients with AN and BN. We assessed female adolescent and young adult inpatients with restrictive type anorexia nervosa (AN-R; n = 20) and BN (n = 20) evaluated in the acute stage of their illness, and 27 female controls. Another group of 20 inpatients with AN-R was assessed on admission and discharge, upon achieving their required weight. Participants completed standardized questionnaires assessing the severity of their eating disorder (ED) and the sensory responsiveness questionnaire (SRQ). Inpatients with AN-R demonstrated elevated overall sensory over-responsiveness as well as elevated scores on the taste/gustatory, vestibular/kinesthetic and somatosensory/tactile SRQ modalities compared with patients with BN and controls. Significant correlations between the severity of sensory over-responsiveness and ED-related symptomatology were found in acutely-ill patients with AN-R and to a lesser extent, following weight restoration. Elevated sensory over-responsiveness was retained in weight-restored inpatients with AN-R. Inpatients with BN demonstrated greater sensory under-responsiveness in the intensity subscale of the SRQ, but not in the frequency and combined SRQ dimensions. Female inpatients with AN-R exhibited sensory over-responsiveness both in the acute stage of their illness and following weight restoration, suggesting that sensory over-responsiveness may represent a trait related to the illness itself above and beyond the influence of malnutrition. The finding for sensory under-responsiveness in BN is less consistent. © 2015 Wiley Periodicals, Inc.

  13. Cardiovascular complications of anorexia nervosa: A systematic review.

    Anorexia nervosa portends the highest mortality among psychiatric diseases, despite primarily being a disease of adolescents and younger adults. Although some of this mortality risk is attributable to suicide, many deaths are likely cardiovascular in etiology. Recent studies suggest that adverse myocardial structural changes occur in this condition, which could underlie the increased mortality. Given limited prevalence of severe anorexia there is a paucity of clinical and autopsy data to discern an exact cause of death. Given this background we conducted a systematic review of the medical literature to provide a contemporary summary of the pathobiologic sequelae of severe anorexia nervosa on the cardiovascular system. We sought to elucidate the impact of anorexia nervosa in four cardiovascular domains: structural, repolarization/conduction, hemodynamic, and peripheral vascular. A number of cardiac abnormalities associated with anorexia nervosa have been described in the literature, including pericardial and valvular pathology, changes in left ventricular mass and function, conduction abnormalities, bradycardia, hypotension, and dysregulation in peripheral vascular contractility. Despite the prevalent theory that malignant arrhythmias are implicated as a cause of sudden death in this disorder, data to support this causal relationship are lacking. It is reasonable to obtain routine electrocardiography and measurements of orthostatic vital signs in patients presenting with anorexia nervosa. Echocardiography is generally not indicated unless prompted by clinical signs of disease. Admission to an inpatient unit with telemetry monitoring is recommended for patients with severe sinus bradycardia or junction rhythm, marked prolongation of the corrected QT interval, or syncope. © 2015 Wiley Periodicals, Inc.

    To compare body composition patterns before and after complete weight restoration in men with anorexia nervosa. Dual-energy X-ray absorptiometry (DXA) was used to measure body composition patterns in 10 men with anorexia nervosa before and after complete weight restoration, and in 10 healthy men matched to age and patients' post-treatment body mass index (BMI). Before weight restoration, men with anorexia nervosa displayed lower total body fat mass (FM) and lean mass (LBM) than those in the healthy comparison group, with a greater FM loss from the extremity than the trunk region. After short-term weight restoration, patients displayed complete normalization in total LBM and FM, but greater deposition of FM in the trunk region. Short-term weight restoration can normalize body composition patterns in men with anorexia nervosa, but results in a central adiposity phenotype. The clinical implication of this finding is unknown, but should be explored given the high levels of concern about central adiposity in anorexia nervosa. © 2017 Wiley Periodicals, Inc.

  15. Neurofunctional areas related to food appetency in anorexia nervosa

    Full Text Available In Anorexia Nervosa the observable phenomenon is the suppression of appetite. Little is known about the biological and psychological (top-down bases that maintain this pathological state. However, Anorexia Nervosa is a biological, psychological and social model where the main behavioral characteristic is the inhibition of eating behavior; not by bottom-up but top-down regulation. Objective: To explore the areas of the brain associated with food appetency through functional magnetic resonance in women with anorexia nervosa. Methods: The subjects include 5 female with Restrictive type of Anorexia Nervosa and five controls female with similar in age and low weigh. The subjects were within the MRI scanner and while took fMRI they saw food images that would generate appetite. The subjects were in fasting state and mentally prepare by instruction “imagine you are eating the food presented in the following images”. Results: Compared differences in the activation between subjects four regions were found significant: the anterior cingulate, left front medial region and the left and right midbrain. Conclusions: The patients with Anorexia Nervosa present different activated cerebral areas to those of the controls during the visual exposition to food in hungry state and with evoke cognitions associated with eat food; those regions may be implicated in reward and self-control.

    Previous studies have explored differences in psychosocial and familial factors between women who develop anorexia nervosa and those who do not. However, these studies have generally used between-group comparisons. This study looks at the environmental factors which may be antecedents of anorexia nervosa looking at sister pairs where one had anorexia nervosa and the other did not. A paired design was used to compare anorexic women with an unaffected sister on a number of background variables, including sibling interaction, parental care, peer group characteristics and other events unique to the individual. The Sibling Inventory of Differential Experience (SIDE) was used to determine non-shared environment. Out of an initial sample of 148 women with past or current anorexia nervosa, 28 were identified who had sisters with no reported history of eating disorders and who also consented to complete the questionnaire. Anorexic sisters perceived more maternal control and reported more antagonism towards and jealousy of their sisters than did unaffected sisters. In addition, anorexic women reported having had fewer friends and boyfriends than their sisters. These results confirm the perceived differences in background environment between women with and women without anorexia nervosa. These issues are discussed in relation to behavioural genetics, family dynamics and psychosexual development.

  17. Total body water and total body potassium in anorexia nervosa

    1984-08-01

    In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

  18. [Adipocytokines: potential biomarkers for childhood obesity and anorexia nervosa].

    Leoni, M C; Pizzo, D; Marchi, A

    2010-04-01

    Adipose tissue is now considered an important endocrine organ that secretes a large number of physiologically active peptides affecting metabolic homeostasis of human body: they are collectively referred to as adipocytokines. Leptin is a key hormone in the regulation of food intake, energy expenditure, neuroendocrine and immune function. Leptin is related with obesity and its metabolic disorders; starvation-induced depletion of fat stores is accompanied by alterations of circulating adipocytokines that may have potential repercussions in the pathophysiology of anorexia nervosa. Adiponectin enhances insulin sensitivity, controls body weight, prevents atherosclerosis and negatively regulates immune functions. Plasma adiponectin relates inversely to adiposity and reflects the sequelae of accumulation of excess adiposity. Resistin is a protein hormone produced both by adipocytes and immunocompetent cells that affect fuel homeostasis and insulin action. Plasma resistin levels are decreased in anorectic patients, while plasma adiponectin levels are increased. Plasma ghrelin levels present opposite changes in obesity and anorexia nervosa, suggesting that ghrelin is a good marker of nutritional status. Visfatin shows to correlate with visceral fat mass in patients with obesity. Its possible role in patients with anorexia nervosa is unknown. In conclusion, obesity is defined as a state of low-grade inflammation, which is associated with increased leptin, resistin and ghrelin levels and decreased adiponectin levels; anorexia nervosa is characterized by opposite changes. Finally, plasma adipocytokines levels can represent a sensitive parameter of nutritional status that reflects changes in the level of body fat in children and adolescents with obesity and anorexia nervosa.

    Schulze, U; Neudörfl, A; Krill, A; Warnke, A; Remschmidt, H; Herpertz-Dahlmann, B

    1997-03-01

    In a two-center follow-up study on the early-onset form of anorexia nervosa, we reexamined 43 (74%) of 58 former patients who had developed anorexia nervosa at the age of 13 years or younger. In addition to make a standardized assessment of the eating disorder at follow-up we assessed psychiatric comorbidity with a structured interview based on the criteria of DSM-III-R and ICD-10. After an average follow-up period of 6.8 years, 8 (18%) of our former patients had an eating disorder not otherwise specified (EDNOS) and 4 (9%) still suffered from anorexia nervosa. 5 (11%) of the subjects had developed bulimia nervosa. In 3 cases (7%) we found both syndromes. 12 (28%) of our former patients had an additional psychiatric disorder. The results of our study indicate that the quality of outcome in patients with an early-onset form of anorexia nervosa does not differ from that in individuals with a later manifestation of the eating disorder. Factors of prognostic relevance were the existence of an eating disorder during the first year of life and the duration of the follow-up period.

  1. The stigma of clean dieting and orthorexia nervosa.

    2017-01-01

    Although the stigma of eating disorders such as anorexia has been well established, little is known about the social consequences of "clean dieting" and orthorexia nervosa. In two studies, we examined the social stigma of clean dieting and orthorexia. In Study 1, participants read a vignette describing a woman following a "clean" diet, a woman with anorexia, or a control target (minimal information about the individual). In Study 2, participants read a vignette describing a woman with orthorexia, a woman displaying identical orthorexic behaviors but without the orthorexia label, a woman with anorexia, or a control target. Participants then rated the target individual on a range of measures assessing stereotypes, emotions, and behavioral intentions toward the target. Study 1 found that the clean-dieting target was evaluated more negatively than the control target on some dimensions, but less negatively than the target with anorexia nervosa. Study 2 found that evaluations of the targets with orthorexia nervosa were more negative than evaluations of a control target, but did not differ from evaluations of the target with anorexia nervosa. Perceptions of the target's control over her behavior were associated with more positive evaluations (Studies 1 and 2), whereas perceptions of blame and responsibility for the condition were associated with more negative evaluations (Study 2). Overall, these findings highlight the potential negative social consequences of clean dieting and orthorexia nervosa, and point to perceptions of control and blame as potential mechanisms underlying the stigma of these conditions.

    2014-12-01

    Full Text Available Powdery mildew (PM is a fungal disease that damages many crops, including grapes. In California, wine, raisin, and table grapes contributed over $3.9 billion to the value of farm production in 2011. Grape varieties with resistance to powdery mildew are currently being developed, using either conventional or transgenic approaches, each of which has associated advantages and disadvantages. PM-resistant varieties of grapes could yield large economic benefits to California grape growers—potentially allowing cost savings as high as $48 million per year in the subset of the industry covered by our analysis (Crimson Seedless table grapes, all raisin grapes, and Central Coast Chardonnay wine grapes, but benefits range widely across the different grape production systems.

  4. A summary of recent results from the GRAPES-3 experiment

    Gupta S.K.

    2017-01-01

    Full Text Available The GRAPES-3 experiment is a combination of a high density extensive air shower (EAS array of nearly 400 plastic scintillator detectors, and a large 560 m2 area tracking muon telescope with an energy threshold Eμ >1 GeV. GRAPES-3 has been operating continuously in Ooty, India since 2000. By accurately correcting for the effects of atmospheric pressure and temperature, the muon telescope provides a high precision directional survey of the galactic cosmic ray (GCR intensity. This telescope has been used to observe the acceleration of muons during thunderstorm events. The recent discovery of a transient weakening of the Earth's magnetic shield through the detection of a GCR burst was the highlight of the GRAPES-3 results. We have an ongoing major expansion activity to further enhance the capability of the GRAPES-3 muon telescope by doubling its area.

  5. Complex Interplay of Hormonal Signals during Grape Berry Ripening

    Ana Margarida Fortes

    2015-05-01

    Full Text Available Grape and wine production and quality is extremely dependent on the fruit ripening process. Sensory and nutritional characteristics are important aspects for consumers and their development during fruit ripening involves complex hormonal control. In this review, we explored data already published on grape ripening and compared it with the hormonal regulation of ripening of other climacteric and non-climacteric fruits. The roles of abscisic acid, ethylene, and brassinosteroids as promoters of ripening are discussed, as well as the role of auxins, cytokinins, gibberellins, jasmonates, and polyamines as inhibitors of ripening. In particular, the recently described role of polyamine catabolism in grape ripening is discussed, together with its putative interaction with other hormones. Furthermore, other recent examples of cross-talk among the different hormones are presented, revealing a complex interplay of signals during grape development and ripening.

    WRKY transcription factors have functions in plant growth and development and in response to biotic and abiotic stresses. Many studies have focused on functional identification of WRKY transcription factors, but little is known about the molecular phylogeny or global expression patterns of the complete WRKY family. In this study, we identified 80 WRKY proteins encoded in the grape genome. Based on the structural features of these proteins, the grape WRKY genes were classified into three groups (groups 1-3). Analysis of WRKY genes expression profiles indicated that 28 WRKY genes were differentially expressed in response to biotic stress caused by grape whiterot and/or salicylic acid (SA). In that 16 WRKY genes upregulated both by whiterot pathogenic bacteria and SA. The results indicated that 16 WRKY proteins participated in SA-dependent defense signal pathway. This study provides a basis for cloning genes with specific functions from grape.

    2013-01-01

    Full Text Available The effect of 1% chitosan combined with 2% β-cyclodextrin to the preservation of fresh grapes under ambient temperature was investigated. The results indicated that the hydrogen bond formed between the hydroxyl group of β-cyclodextrin and the amidogen or hydroxyl group of chitosan and the crystal form of chitosan was also changed when cyclodextrin was doped into chitosan coating. The compound coating could prolong the shelf life of grapes, maintain lower respiration rate and higher activities of superoxide dismutase, peroxidase, and catalase during storage time, and restrain weight loss and malonaldehyde content increase. Coating grapes with chitosan + β-cyclodextrin was a good method in postharvested grape preservation.

    Full Text Available Grape brandy is a product obtained by fermentation and distillation of crushed grapes of cultivated grapevine Vitis vinifera. Grape brandy quality depends on many factors such as: grapevine varieties, climate, soil, time and method of distillation, storage methods and other distillates. The grapevine variety 'Neoplanta' grown in the experimental field of the PD 'Center for Viticulture and Enology' in Niš was used in the experiment. Tests were performed in the laboratory of the Centre. Healthy grapes of harvest maturity were squashed by a stalk-removing electric crusher. Fermentation was performed in plastic containers in the presence of the indigenous microflora of wine yeasts. This paper presents the influence of pH and inorganic nitrogen added to the fermentation medium on the content of volatile components and concentrations of higher alcohols.

    Objective Anorexia nervosa is a psychiatric illness characterized by low weight, disordered eating, and hallmark neuroendocrine dysfunction. Behavioral phenotypes are defined by predominant restriction or bingeing/purging; binge-eating/purging type anorexia nervosa is associated with poorer outcome. The pathophysiology underlying anorexia nervosa types is unknown, but altered hormones, known to be involved in eating behaviors, may play a role. Method To examine the role of anorexigenic hormones in anorexia nervosa subtypes, we examined serum levels of peptide YY (PYY; total and active [3-36] forms), brain-derived neurotrophic factor (BDNF), and leptin as primary outcomes in women with OSM-5 restricting type anorexia nervosa (n=50), binge-eating/purging type anorexia nervosa (n = 22), and healthy controls (n = 22).1n addition, women completed validated secondary outcome measures of eating disorder psychopathology (Eating Disorder Examination-Questionnaire) and depression and anxiety symptoms (Hamilton Rating Scales for Depression [HDRS] and Anxiety [HARS]). The study samples were collected from May 22, 2004, to February 7, 2012. Results Mean PYY 3-36 and leptin levels were lower and BDNF levels higher in binge-eating/purging type anorexia nervosa than in restricting type anorexia nervosa (all Pvalues anorexia nervosa types were significant (Panorexia nervosa, the anorexigenic hormones PYY, BDNF, and leptin are differentially regulated between the restricting and binge/purge types. Whether these hormone pathways play etiologic roles with regard to anorexia nervosa behavioral types or are compensatory merits further study. PMID:25098834

    Aedes albopictus is an important arbovirus vector, including dengue. Currently, there is no specific treatment for dengue. Its prevention solely depends on effective vector control measures. In this study, silver nanoparticles (AgNPs) were biosynthesized using a cheap leaf extract of Berberis tinctoria as reducing and stabilizing agent and tested against Ae. albopictus and two mosquito natural enemies. AgNPs were characterized by using UV–vis spectrophotometry, X-ray diffraction, and scanning electron microscopy. In laboratory conditions, the toxicity of AgNPs was evaluated on larvae and pupae of Ae. albopictus. Suitability Index/Predator Safety Factor was assessed on Toxorhynchites splendens and Mesocyclops thermocyclopoides. The leaf extract of B. tinctoria was toxic against larval instars (I–IV) and pupae of Ae. albopictus; LC50 was 182.72 ppm (I instar), 230.99 ppm (II), 269.65 ppm (III), 321.75 ppm (IV), and 359.71 ppm (pupa). B. tinctoria-synthesized AgNPs were highly effective, with LC50 of 4.97 ppm (I instar), 5.97 ppm (II), 7.60 ppm (III), 9.65 ppm (IV), and 14.87 ppm (pupa). Both the leaf extract and AgNPs showed reduced toxicity against the mosquito natural enemies M. thermocyclopoides and T. splendens. Overall, this study firstly shed light on effectiveness of B. tinctoria-synthesized AgNPs as an eco-friendly nanopesticide, highlighting the concrete possibility to employ this newer and safer tool in arbovirus vector control programs.

  20. Long-Term Effects of Berberis thunbergii (Ranunculales: Berberidaceae) Management on Ixodes scapularis (Acari: Ixodidae) Abundance and Borrelia burgdorferi (Spirochaetales: Spirochaetaceae) Prevalence in Connecticut, USA.

    Japanese barberry (Berberis thunbergii de Candolle; Ranunculales: Berberidaceae) is an exotic invasive shrub that escaped cultivation in the United States and is now permanently established in many eastern and midwestern states. This study examined the long-term impacts of Japanese barberry management on blacklegged tick (Ixodes scapularis Say; Acari: Ixodidae) abundances and associated prevalence of Borrelia burgdorferi (Johnson, Schmid, Hyde, Steigerwalt, and Brenner; Spirochaetales: Spirochaetaceae), the etiologic agent of Lyme disease. At six locations across Connecticut, adult I. scapularis were sampled for up to 10 yr. At each location, we sampled an area where barberry infestations were unmanipulated, adjacent areas where barberry was virtually nonexistent, and areas where barberry was managed utilizing a variety of techniques. Barberry management reduced B. burgdorferi-infected adult I. scapularis (BBIAIS) abundances (191/ha ± 64 SE) over 6 yr to statistically indifferent from that of no barberry areas (140/ha ± 47 SE; P = 0.080) and significantly less than intact barberry stands (458/ha ± 80 SE; P = 0.026). Over 9 yr, BBIAIS abundances in managed barberry remained lower than intact barberry stands (P = 0.037), but increased to be significantly greater than no barberry areas (P = 0.007) as cover increased over time. Longer-term data further document that Japanese barberry infestations are favorable habitat for I. scapularis. Control of Japanese barberry and other invasives should be at least on a 5-yr rotation to maintain low levels of invasive cover and eliminate humidity refugia to expose juvenile I. scapularis to more hostile environmental conditions in the interest of public health. © The Authors 2017.

    Berberis lycium Royle (Berberidacea) from Pakistan and its alkaloids berberine and palmatine have been reported to possess beneficial pharmacological properties. In the present study, the anti-neoplastic activities of different B. lycium root extracts and the major constituting alkaloids, berberine and palmatine were investigated in p53-deficient HL-60 cells. The strongest growth inhibitory and pro-apoptotic effects were found in the n-butanol (BuOH) extract followed by the ethyl acetate (EtOAc)-, and the water (H 2 O) extract. The chemical composition of the BuOH extract was analyzed by TLC and quantified by HPLC. 11.1 μg BuOH extract (that was gained from 1 mg dried root) contained 2.0 μg berberine and 0.3 μg/ml palmatine. 1.2 μg/ml berberine inhibited cell proliferation significantly, while 0.5 μg/ml palmatine had no effect. Berberine and the BuOH extract caused accumulation of HL-60 cells in S-phase. This was preceded by a strong activation of Chk2, phosphorylation and degradation of Cdc25A, and the subsequent inactivation of Cdc2 (CDK1). Furthermore, berberine and the extract inhibited the expression of the proto-oncogene cyclin D1. Berberine and the BuOH extract induced the acetylation of α-tubulin and this correlated with the induction of apoptosis. The data demonstrate that berberine is a potent anti-neoplastic compound that acts via anti-proliferative and pro-apoptotic mechanisms independent of genotoxicity.

  2. Anorexia nervosa and major depression: shared genetic and environmental risk factors.

    Wade, T D; Bulik, C M; Neale, M; Kendler, K S

    2000-03-01

    The authors sought to derive heritability estimates for anorexia nervosa and to explore the etiology of the comorbid relationship between anorexia nervosa and major depression. They applied bivariate structural equation modeling to a broad definition of anorexia nervosa and lifetime major depression as assessed in a population-based sample of 2,163 female twins. Anorexia nervosa was estimated to have a heritability of 58% (95% confidence interval=33%-84%). The authors were unable to completely rule out a contribution of shared environment. The comorbidity between anorexia nervosa and major depression is likely due to genetic factors that influence the risk for both disorders. Although the study was limited by the small number of affected twins, the results suggest that genetic factors significantly influence the risk for anorexia nervosa and substantially contribute to the observed comorbidity between anorexia nervosa and major depression.

  5. Consumer Acceptability of Fresh-Market Muscadine Grapes.

    Brown, Kelly; Sims, Charles; Odabasi, Asli; Bartoshuk, Linda; Conner, Patrick; Gray, Dennis

    2016-10-14

    The objective of this research was to investigate the acceptability of muscadine grape (Vitis rotundifolia) genotypes (cultivars and selections) and to correlate overall liking to other quality measurements to determine the main drivers of liking. Twenty-two genotypes grown at the Univ. of Georgia-Tifton Campus were evaluated. Four retail commercial grape genotypes (Vitis vinifera and "Concord") were also evaluated for comparison. Panelists familiar with muscadine grapes used the hedonic general labeled magnitude scale (HgLMS, -100 = strongest disliking of any kind ever experienced, +100 = strongest liking of any kind ever experienced) to rate overall liking and the liking of appearance, flavor, pulp texture, and skin texture. Puncture testing was done to assess grape berry texture, and compositional attributes soluble solids and pH were also measured. The sensory results indicated that the grapes were variable with overall liking scores from 12.2 to 39.6. The factors highly correlated with overall liking scores were muscadine flavor, pulp and skin liking, while a significant negative correlation was found between skin liking and skin texture and mechanical texture measures. The muscadine grapes with the highest overall liking scores were Ga. 5-1-34 and Ga. 2-8-21. Principal component analysis confirmed that grapes with a thinner skin and a higher pH tended to group around overall liking and flavor points. These results indicate that even among panelists familiar with muscadine grapes, skin thickness is a negative characteristic. Breeding for thinner skins may be a positive step in muscadines gaining a more widespread appeal in the fresh fruit market. © 2016 Institute of Food Technologists®.

    Highlights: • The effects of treatment temperature and liquid pH on char and liquid properties. • Liquid pH had a statistically significant effect only on liquid carbon yield. • Higher treatment temperature increased char volatiles that can enhance ignitability. • Char showed promising fuel properties if elevated ash phosphorus can be tolerated. - Abstract: The treatment and disposal of grape marc, a residue from grape processing, represents a significant economic and environmental challenge for the winemaking industry. Hydrothermal treatment of grape marc could be an efficient way for producing solid fuels on-site at the wineries. In this work the effects of treatment temperature and liquid pH on grape marc char and liquid properties were determined based on laboratory experiments and the combustion characteristics of char were assessed through thermogravimetric analysis and fuel ash classification. The results showed that hydrothermal treatment increased the energy and carbon contents and decreased the ash content of grape marc. The effect of liquid pH was statistically significant (p < 0.05) only for the determined carbon yield of liquid samples. The energy yield from grape marc was maximized at lower treatment temperatures, which also decreased the content of less thermally stable compounds in the attained char. Higher treatment temperatures decreased grape marc solid, carbon and energy yields and led to an increase in thermally labile compounds compared to lower temperatures likely due to the condensation of liquid compounds or volatiles trapped in the pores of char particles. The alkali metal contents of char ash were reduced coupled with an increase in respective phosphorus. Overall the results support the use of hydrothermally treated grape marc in solid fuel applications, if elevated levels of ash phosphorus can be tolerated.

  7. Remission of anorexia nervosa after thyroidectomy: A report of two cases with Graves' disease and anorexia nervosa

    Noguchi Hitoshi

    2011-12-01

    Full Text Available Abstract We report two patients with anorexia nervosa and Graves' disease who received subtotal thyroidectomy for Graves' disease and concomitantly experienced remission from anorexia nervosa. Both were young women (aged 20 and 26 at the time of surgery. Both had well controlled thyroid function and eating behavior at the time of surgery. Both were followed for over five years without relapse of anorexia nervosa or hyperthyroidism. These cases suggest the existence of an endocrine factor originating from the thyroid gland that is involved in the pathogenesis of anorexia nervosa. Since patients of thyroidectomy can remain in good health with supplement of thyroxine alone, it can be hypothesized that this anorexigenic endocrine factor is an evolutionary relic not necessary for the normal function of humans and does not have physiological effects unless secreted beyond normal levels. Given that, it implies the existence of a creature in the animal kingdom for which such an anorexigenic hormone is essential for survival. Migrating birds eat beyond their caloric expenditure before migration and become anorexic for the duration of their flight. It is also known that their thyroid function is elevated during migration. The normal physiology of migration is a complex mechanism involving the hypothalamic, pituitary, thyroid, adrenal and reproductive hormones. The mechanism of disease, however, can be simpler. A review of the literature is presented that suggest a heretofore unreported thyroid hormone, which is involved in the regulation of migration behavior, may be the responsible factor behind anorexia nervosa.

  8. Effect of commercial grape extracts on the cheese-making properties of milk.

    Felix da Silva, Denise; Matumoto-Pintro, Paula T; Bazinet, Laurent; Couillard, Charles; Britten, Michel

    2015-03-01

    Grape extracts can be added to milk to produce cheese with a high concentration of polyphenols. Four commercial extracts from whole grape, grape seed, and grape skin (2 extracts) were characterized and added to milk at concentrations of 0, 0.1, 0.2, and 0.3% (wt/vol). The effect of grape extracts on the kinetics of milk clotting, milk gel texture, and syneresis were determined, and model cheeses were produced. Whole grape and grape seed extracts contained a similar concentration of polyphenolic compounds and about twice the amount found in grape skin extracts. Radical scavenging activity was directly proportional to the phenolic compounds content. When added to milk, grape extracts increased rennet-induced clotting time and decreased the clotting rate. Although differences were observed between the extracts, the concentration added to milk was the main factor influencing clotting properties. With increasing concentrations of grape extracts, milk gels showed increased brittleness and reduced firmness. In addition, syneresis of milk gels decreased with increasing concentrations of grape extracts, which resulted in cheeses with a higher moisture content. The presence of grape extracts in milk slightly increased protein recovery in cheese but had no effect on fat recovery. With whole grape or grape seed extracts added to milk at 0.1% (wt/vol), the recovery coefficient for polyphenols was about 0.63, and decreased with increasing extract concentration in milk. Better polyphenol recovery was observed for grape seed extracts (0.87), with no concentration effect. Commercial extracts from whole grape, grape seed, or grape skin can be added to milk in the 0.1 to 0.3% (wt/vol) concentration range to produce cheese with potential health benefits, without a negative effect on cheese yield.

    Prozil, Sónia O; Evtuguin, Dmitry V; Silva, Artur M S; Lopes, Luísa P C

    2014-06-18

    The chemical structure of lignin from grape stalks, an abundant waste of winemaking, has been studied. The dioxane lignin was isolated from extractive- and protein-free grape stalks (Vitis vinifera L.) by modified acidolytic procedure and submitted to a structural analysis by wet chemistry (nitrobenzene and permanganate oxidation (PO)) and spectroscopic techniques. The results obtained suggest that grape stalk lignin is an HGS type with molar proportions of p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units of 3:71:26. Structural analysis by (1)H and (13)C NMR spectroscopy and PO indicates the predominance of β-O-4' structures (39% mol) in grape stalk lignin together with moderate amounts of β-5', β-β, β-1', 5-5', and 4-O-5' structures. NMR studies also revealed that grape lignin should be structurally associated with tannins. The condensation degree of grape stalks lignin is higher than that of conventional wood lignins and lignins from other agricultural residues.

    2018-03-24

    One of the main aims of treatment after successful recovery from anorexia nervosa (AN) is to prevent a relapse. The Guideline Relapse Prevention (GRP) Anorexia Nervosa offers a structured approach to relapse prevention. This study explores how patients and their parents experience working with the guideline. It also describes the factors that support or hinder successful application of the guideline. A descriptive qualitative research design was chosen involving in-depth interviews with seventeen patients with anorexia nervosa and six sets of parents. Patients and family members were generally satisfied with the support provided by the GRP. It contributed significantly to a better understanding of the personal process of relapse. Patients and families valued being able to keep in touch with their professional during the aftercare programme. The GRP supports the patient's use of self-management strategies for relapse prevention. © 2018 Australian College of Mental Health Nurses Inc.

  13. Mindfulness in Anorexia Nervosa: An Integrated Review of the Literature.

    Dunne, Julie

    Anorexia nervosa is a serious psychiatric illness with limited evidenced-based treatment options. Mindfulness appears useful in many conditions, but few studies focus on its use in individuals with anorexia nervosa. To examine and summarize studies of mindfulness in individuals with anorexia nervosa and identify areas for future research. An integrated review was conducted by searching health care computerized databases. Results were mixed among the eight studies that met inclusion criteria. Multimodal mindfulness-based therapies appear effective, while brief interventions may be equally useful or result in greater anxiety compared to distraction. Qualitative data support that some participants feel mindfulness is challenging but beneficial. Mindfulness as a concurrent part of therapy and/or when routinely practiced may be more clinically useful than single-episode mindful eating interventions. Due to the complexity of the concept of mindfulness and limited existing data, additional research is needed.

  14. Measuring Orthorexia Nervosa: Psychometric Limitations of the ORTO-15.

    Roncero, María; Barrada, Juan Ramón; Perpiñá, Conxa

    2017-09-20

    Orthorexia nervosa has recently been defined as excessive preoccupation with healthy eating, causing significant nutritional deficiencies and social and personal impairments. The ORTO-15 is the most widely used instrument to evaluate orthorexia nervosa, although previous studies obtained inconsistent results about its psychometric properties, and there are no data on the Spanish version. Thus, the main objective of the present study was to analyze the psychometric properties of the Spanish adaptation of the ORTO-15. In order to cross-validate the results, two independent samples were used (Sample 1: n = 807, 74.1% women; Sample 2: n = 242, 63.2% women). The results did not support the original recoding and reversal of the items; thus, the original scores were maintained. The analysis of the internal structure showed that the best interpretable solution was unidimensional, and due to low loadings, four items were removed. The internal consistency (α = .74) and temporal stability (r = .92; p orthorexia nervosa.

  16. Effects of grape (vitis labrusca b.) peel and seed extracts on phenolics, antioxidants and anthocyanins in grape juice

    Ghafoor, K.; Juhaimi, F.; Choi, Y.H.

    2011-01-01

    Grape peel and seed are good sources of important bioactive components such as phenolics, anthocyanins and antioxidants. Recovery of these components and their proper utilization is important for the development of functional foods. We have utilized the extracts of grape peel and seed obtained by ultrasonic-assisted (UAE) and supercritical fluid extractions (SFE) for the enrichment of Campbell Early grape juice (CEJ). CEJ samples were analyzed for different functional compounds and it was observed that the addition of these extracts in CEJ significantly improved total phenolic compounds, antioxidants, anti radical activities and total anthocyanin contents. HPLC analysis of CEJ samples containing these extracts showed that the phenolic acids (benzoic and cinnamic acids) and catechins contents were also significantly improved with the addition of grape peel and seed extracts. Generally SFE extracts proved to be of superior quality for the functional enrichment in CEJ. The sensory evaluation revealed that the CEJ samples containing the extracts had good overall acceptability. (author)

  17. Cognitive theory in anorexia nervosa and bulimia nervosa: progress, development and future directions.

    Cooper, Myra J

    2005-06-01

    Important developments have taken place in cognitive theory of eating disorders (EDs) (and also in other disorders) since the review paper published by M.J. Cooper in 1997. The relevant empirical database has also expanded. Nevertheless, cognitive therapy for anorexia nervosa and bulimia nervosa, although helpful to many patients, leaves much to be desired. The current paper reviews the relevant empirical evidence collected, and the theoretical revisions that have been made to cognitive models of eating disorders, since 1997. The status and limitations of these developments are considered, including whether or not they meet the criteria for "good" theory. New theoretical developments relevant to cognitive explanations of eating disorders (second generation theories) are then presented, and the preliminary evidence that supports these is briefly reviewed. The lack of integration between cognitive theories of EDs and risk (vulnerability) factor research is noted, and a potential model that unites the two is noted. The implications of the review for future research and the development of cognitive theory in eating disorders are then discussed. These include the need for study of cognitive constructs not yet fully integrated (or indeed not yet applied clinically) into current theories and the need for cognitive theories of eating disorders to continue to evolve (as they have indeed done since 1997) in order to fully integrate such constructs. Treatment studies incorporating these new developments also urgently need to be undertaken.

  18. Depression or depressiveness in patients diagnosed with Anorexia Nervosa and Bulimia Nervosa - pilot research.

    Dêbska, Ewa; Janas, Adam; Bañczyk, Wojciech; Janas-Kozik, Małgorzata

    2011-09-01

    The target of this work is to consider if depressive symptoms intercurrent with patients suffering from Anorexia Nervosa (AN) and Bulimia Nervosa (BN) form a depression complex or whether they are physiological depression accompanying adolescence. We wished to observe the perception of these patients,of their functioning, both social and within their families and also looking for common point in the issues mentioned above trying to locate them within the course of the basic illness. We studied 19 patients suffering from eating disorders, and aged between 12 and 24 years old. 15 of them suffered from the restrictive form of AN and 4 suffered from BN. The control group consisted of 30 healthy girls in the same age interval. In the study authors used the Beck Depression Inventory (BDI) and the Quebec Quality of Life Questionnaire. Comparison of a number of points acquired in the survey using Beck Depression Scale revealed statistic significance at the level pdepression symptoms among persons with eating disorders comparing to control group. The survey using the Questionnaire for Social Quality showed no statistically significant differences between study and control groups (p>0.05). The authors observed a statistically significant increased frequency of suicidal thoughts in the study group compared to the controls. To diagnose depression, depressive symptoms presented by the patients must give the image of depression at the clinical level. The result of the Beck's scale needs to be confronted with the clinical picture. Depression in adolescence requires differentiation from depressiveness.

  19. Understanding the Relation between Anorexia Nervosa and Bulimia Nervosa in a Swedish National Twin Sample

    Bulik, Cynthia M; Thornton, Laura; Root, Tammy L.; Pisetsky, Emily M.; Lichtenstein, Paul; Pedersen, Nancy L.

    2010-01-01

    Background We present a bivariate twin analysis of anorexia nervosa (AN) and bulimia nervosa (BN) to determine the extent to which shared genetic and environmental factors contribute to liability to these disorders. Method Focusing on females from the Swedish Twin study of Adults: Genes and Environment (STAGE) (N=7000), we calculated heritability estimates for narrow and broad AN and BN and estimated their genetic correlation. Results In the full model, the heritability estimate for narrow AN was (a2 = .57; 95% CI: .00, .81) and for narrow BN (a2 = .62; 95% CI: .08, .70) with the remaining variance accounted for by unique environmental factors. Shared environmental factors estimates were (c2 = .00; 95% CI: .00, .67) for AN and (c2 = .00; 95% CI: .00, .40) for BN. Moderate additive genetic (.46) and unique environmental (.42) correlations between AN and BN were observed. Heritability estimates for broad AN were lower (a2 = .29; 95% CI: .04, .43) than for narrow AN, but estimates for broad BN were similar to narrow BN. The genetic correlation for broad AN and BN was .79 and the unique environmental correlation was .44. Conclusions We highlight the contribution of additive genetic factors to both narrow and broad AN and BN and demonstrate a moderate overlap of both genetic and unique environmental factors that influence the two conditions. Common concurrent and sequential comorbidity of AN and BN can in part be accounted for by shared genetic and environmental influences on liability although independent factors also operative.

  20. Orofacial manifestations in outpatients with anorexia nervosa and bulimia nervosa focusing on the vomiting behavior.

    Lourenço, Maria; Azevedo, Álvaro; Brandão, Isabel; Gomes, Pedro S

    2018-06-01

    This case-control study aims to evaluate the oral health status and orofacial problems in a group of outpatients with eating disorders (ED)-either anorexia nervosa (AN) or bulimia nervosa (BN)-further focusing on the influence of vomit. Fifty-five women outpatients with AN or BN diagnosis were invited to participate, of which 33 agreed. ED outpatients and matched controls were submitted to a questionnaire and clinical oral examination. Multivariate analysis identified a significantly higher incidence of teeth-related complications (i.e., tooth decay, dental erosion, and self-reported dentin hypersensitivity), periodontal disease, salivary alterations (i.e., hyposalivation and xerostomia), and oral mucosa-related complications in ED outpatients. Dental erosion, self-reported dentin hypersensitivity, hyposalivation, xerostomia, and angular cheilitis were found to be highly correlated with the vomiting behavior. ED outpatients were found to present a higher incidence of oral-related complications and an inferior oral health status, compared to gender- and age-matched controls. Alterations verified within outpatients were acknowledged to be quite similar to those previously reported within inpatients, in both of nature and severity, thus sustaining that the cranio-maxillofacial region is significantly affected by ED, even in the early/milder forms of the condition, as expectedly verified within outpatients.

  1. Core psychopathology in anorexia nervosa and bulimia nervosa: A network analysis.

    Forrest, Lauren N; Jones, Payton J; Ortiz, Shelby N; Smith, April R

    2018-04-25

    The cognitive-behavioral theory of eating disorders (EDs) proposes that shape and weight overvaluation are the core ED psychopathology. Core symptoms can be statistically identified using network analysis. Existing ED network studies support that shape and weight overvaluation are the core ED psychopathology, yet no studies have estimated AN core psychopathology and concerns exist about the replicability of network analysis findings. The current study estimated ED symptom networks among people with anorexia nervosa (AN) and bulimia nervosa (BN) and among a combined group of people with AN and BN. Participants were girls and women with AN (n = 604) and BN (n = 477) seeking residential ED treatment. ED symptoms were assessed with the Eating Disorder Examination-Questionnaire (EDE-Q); 27 of the EDE-Q items were included as nodes in symptom networks. Core symptoms were determined by expected influence and strength values. In all networks, desiring weight loss, restraint, shape and weight preoccupation, and shape overvaluation emerged as the most important symptoms. In addition, in the AN and combined networks, fearing weight gain emerged as an important symptom. In the BN network, weight overvaluation emerged as another important symptom. Findings support the cognitive-behavioral premise that shape and weight overvaluation are at the core of AN psychopathology. Our BN and combined network findings provide a high degree of replication of previous findings. Clinically, findings highlight the importance of considering shape and weight overvaluation as a severity specifier and primary treatment target for people with EDs. © 2018 Wiley Periodicals, Inc.

    Research supports that anorexia nervosa-restricting subtype (AN-R) and bulimia nervosa (BN) are associated with emotion regulation difficulties and alexithymia. However, the impact of diagnosis on the relationship between these constructs is less well understood. The purpose of the present study was to examine whether eating disorder diagnosis moderated the association between admission alexithymia and emotion regulation through discharge. Adult patients with AN-R (n = 54) and BN (n = 60) completed assessments at treatment admission and discharge from a partial hospital program. Eating disorder diagnosis moderated the association between admission alexithymia levels and change in global emotion dysregulation, impulse control difficulties and access to emotion regulation strategies. At higher levels of admission alexithymia, there were no differences between AN-R and BN on emotion dysregulation, whereas at lower levels of alexithymia, AN-R patients demonstrated lower levels of emotion dysregulation. Results imply that difficulties with alexithymia appear to have a greater impact on emotion dysregulation for AN-R patients. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

    2003-01-01

    The aim of the study was to investigate whether the use of purgative methods in patients with eating disorders (anorexia nervosa [AN] and bulimia nervosa [BN]) could be capable of producing changes in the nutritional status of the patients. The group under study was composed of 184 female eating disordered outpatients. One hundred and sixteen patients (63.0%) fulfilled the DSM-IV diagnostic criteria for BN (90 purging type, 26 nonpurging type). Sixty eight patients (37.0%) fulfilled the DSM-IV criteria for the diagnosis of AN (48 restricting type, 20 binging-purging type). The assessment process included anthropometry (body circumferences and skinfold thickness) and body impedance analysis. The two subgroups of AN patients significantly differed from each of the BN subgroups. From a nutritional point of view, some significant differences between the two DSM-IV subtypes of AN existed, but not between the purging type and the nonpurging type of BN. The paper discusses the clinical significance of these findings. An alternative subtypification of AN patients is proposed: 1) restricting type [patients who control their food intake and do not purge]; 2) purging type [patient with true episodes of binging which are followed by purgative behaviors]; and 3) pseudopurging type [patients with subjective binging episodes who use purging methods].

    We examined eating disorders in midlife and beyond by comparing frequency of anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding or eating disorder (OSFED) among midlife eating disorder treatment-seeking individuals and younger controls. We also compared demographic and eating disorder-related characteristics across diagnoses and age groups. Participants included 2,118 treatment-seeking adults who self-reported their eating-related symptoms on the Eating Disorder Questionnaire. Results showed that percent of patients with BN was significantly lower whereas percent of patients with BED and OSFED was significantly higher among midlife relative to younger patients. Percent of patients with AN did not differ between midlife and younger patients. Additionally, midlife and younger patients with BED and OSFED differed on several demographic (e.g., marital status) and eating disorder-related characteristics (e.g., BMI, compulsive exercising). This study suggests that BN is less common whereas BED and OSFED are more common among midlife eating disorder treatment-seeking individuals relative to younger controls. In addition, AN and BN present fairly similarly whereas BED and OSFED present fairly differently among midlife patients relative to younger controls. Attention to these differences and similarities is necessary to understand eating disorders in midlife.

  5. Trail making task performance in inpatients with anorexia nervosa and bulimia nervosa.

    Vall, Eva; Wade, Tracey D

    2015-07-01

    Set-shifting inefficiencies have been consistently identified in adults with anorexia nervosa (AN). It is less clear to what degree similar inefficiencies are present in those with bulimia nervosa (BN). It is also unknown whether perfectionism is related to set-shifting performance. We employed a commonly used set-shifting measure, the Trail Making Test (TMT), to compare the performance of inpatients with AN and BN with a healthy control sample. We also investigated whether perfectionism predicted TMT scores. Only the BN sample showed significantly suboptimal performance, while the AN sample was indistinguishable from controls on all measures. There were no differences between the AN subtypes (restrictive or binge/purge), but group sizes were small. Higher personal standards perfectionism was associated with better TMT scores across groups. Higher concern over mistakes perfectionism predicted better accuracy in the BN sample. Further research into the set-shifting profile of individuals with BN or binge/purge behaviours is needed. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.

    This study examined the underlying processes of decision-making impairments in individuals with anorexia nervosa (AN) and bulimia nervosa (BN). We deconstructed their performance on the widely used decision task, the Iowa Gambling Task (IGT) into cognitive, motivational, and response processes using cognitive modeling analysis. We hypothesized that IGT performance would be characterized by impaired memory functions and heightened punishment sensitivity in AN, and by elevated sensitivity to reward as opposed to punishment in BN. We analyzed trial-by-trial data of IGT obtained from 224 individuals: 94 individuals with AN, 63 with BN, and 67 healthy comparison individuals (HC). The prospect valence learning model was used to assess cognitive, motivational, and response processes underlying IGT performance. Individuals with AN showed marginally impaired IGT performance compared to HC. Their performance was characterized by impairments in memory functions. Individuals with BN showed significantly impaired IGT performance compared to HC. They showed greater relative sensitivity to gains as opposed to losses than HC. Memory functions in AN were positively correlated with body mass index. This study identified differential impairments underlying IGT performance in AN and BN. Findings suggest that impaired decision making in AN might involve impaired memory functions. Impaired decision making in BN might involve altered reward and punishment sensitivity.

    This study is the result of two Portuguese case-control studies that examined the replication of retrospective correlates and preceding life events in anorexia nervosa (AN) and bulimia nervosa (BN) development. This study aims to identify retrospective correlates that distinguish AN and BN METHOD: A case-control design was used to compare a group of women who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for AN (N = 98) and BN (N = 79) with healthy controls (N = 86) and with other psychiatric disorders (N = 68). Each control group was matched with AN patients regarding age and parental social categories. Risk factors were assessed by interviewing each person with the Oxford Risk Factor Interview. Compared to AN, women with BN reported significantly higher rates of paternal high expectations, excessive family importance placed on fitness/keeping in shape, and negative consequences due to adolescent overweight and adolescent objective overweight. Overweight during adolescence emerged as the most relevant retrospective correlate in the distinction between BN and AN participants. Family expectations and the importance placed on keeping in shape were also significant retrospective correlates in the BN group.

    Decision-making (DM) abilities have been found to be impaired in anorexia nervosa (AN), but few data are available about the characteristics and correlates of this cognitive function. The aim of the present study was to provide data on DM functioning in AN using both veridical and adaptive paradigms. While in veridical DM tasks, the individual's ability to predict a true/false response is measured, adaptive DM is the ability to consider both internal and external demands in order to make a good choice, in the absence of a single true "correct" answer. The participants were 189 women, of whom 91 were eating-disordered patients with a lifetime diagnosis of anorexia nervosa, and 98 were healthy women. All the participants underwent clinical, neuropsychological, and genetic assessment. The cognitive evaluation included a set of neuropsychological tasks and two decision-making tests: The Iowa Gambling Task and the Cognitive Bias Task. Anorexia nervosa patients showed significantly poorer performances on both decision-making tasks than healthy women. The Cognitive Bias Task revealed that anorexia nervosa patients employed significantly more context-independent decision-making strategies, which were independent from diagnostic subtype, handedness, education, and psychopathology. In the whole sample (patients and controls), Cognitive Bias Task performance was independently predicted by lifetime anorexia nervosa diagnosis, body mass index at assessment, and 5-HTTLPR genotype. Patients displayed poor decision-making functioning in both veridical and adaptive situations. The difficulties detected in anorexia nervosa individuals may affect not only the ability to consider the future outcomes of their actions (leading to "myopia for the future"), but also the capacity to update and review one's own mindset according to new environmental stimuli.

  9. Glucocorticoid receptors in anorexia nervosa and Cushing's disease.

    1999-06-01

    Patients with anorexia nervosa do not display cushingoid features in spite of elevated cortisol plasma levels. Whether a cortisol resistance or a reduced availability of the metabolic substrates necessary to develop the effect of glucocorticoids is responsible for this has not been established. Twenty-two patients with severe restrictive anorexia nervosa, 10 patients with active Cushing's disease, and 24 healthy volunteers without psychiatric disorders or mood alterations were investigated. Glucocorticoid receptor characteristics were examined on mononuclear leukocytes by measuring [3H]dexamethasone binding and the effect of dexamethasone on [3H]thymidine incorporation, which represents an index of DNA synthesis. The number of glucocorticoid receptors on mononuclear leukocytes (MNL) was comparable in patients with anorexia nervosa, patients with active Cushing's disease, and normal subjects (binding capacity 3.3 +/- 0.23 vs. 3.7 +/- 0.30 and 3.5 +/- 0.20 fmol/10(6) cells). Conversely, glucocorticoid receptor affinity was significantly decreased in anorexia nervosa as well as in Cushing's patients compared to control subjects (dissociation constant 4.0 +/- 0.31 and 4.1 +/- 0.34 vs. 2.9 +/- 0.29 nmol/L, p Cushing's patients compared to control subjects (p Cushing's disease. In patients with anorexia nervosa, the incorporation of [3H]thymidine into the MNL was inversely correlated with urinary free cortisol levels. These data indicate that the lack of cushingoid features in patients with anorexia nervosa is not ascribable to a reduced sensitivity to glucocorticoids but is more likely due to the paucity of metabolic substrates.

    2016-01-01

    The therapeutic working alliance is a vital ingredient of psychotherapy, specifically for clients diagnosed with anorexia nervosa, as progress is often slow and treatment difficult. This qualitative phenomenological study investigated the experiences of eight clients with anorexia nervosa and seven therapists who work with this population, regarding which therapist factors aided in and challenged the working alliance formation in individual psychotherapy. Data was gathered through semi-structured interviews. Some helpful therapist factors included collaboration, appropriate self-disclosure, providing a warm and safe environment, and willingness to be contacted outside of a session. Unhelpful factors included lack of attunement and objectivity and failure to individualize treatment.

  16. Attention networks in adolescent anorexia nervosa.

    Weinbach, Noam; Sher, Helene; Lock, James D; Henik, Avishai

    2018-03-01

    Anorexia nervosa (AN) usually develops during adolescence when considerable structural and functional brain changes are taking place. Neurocognitive inefficiencies have been consistently found in adults with enduring AN and were suggested to play a role in maintaining the disorder. However, such findings are inconsistent in children and adolescents with AN. The current study conducted a comprehensive assessment of attention networks in adolescents with AN who were not severely underweight during the study using an approach that permits disentangling independent components of attention. Twenty partially weight-restored adolescents with AN (AN-WR) and 24 healthy adolescents performed the Attention Network Test which assesses the efficiency of three main attention networks-executive control, orienting, and alerting. The results revealed abnormal function in the executive control network among adolescents with AN-WR. Specifically, adolescents with AN-WR demonstrated superior ability to suppress attention to task-irrelevant information while focusing on a central task. Moreover, the alerting network modulated this ability. No difference was found between the groups in the speed of orienting attention, but reorienting attention to a target resulted in higher error rates in the AN-WR group. The findings suggest that adolescents with AN have attentional abnormalities that cannot be explained by a state of starvation. These attentional dysregulations may underlie clinical phenotypes of the disorder such as increased attention of details.

  17. Compulsivity in Anorexia Nervosa: a transdiagnostic concept

    Lauren Rose Godier

    2014-07-01

    Full Text Available The compulsive nature of weight loss behaviours central to Anorexia Nervosa (AN, such as relentless self-starvation and over-exercise, has led to the suggestion of parallels between AN and other compulsive disorders such as Obsessive-Compulsive Disorder (OCD and addictions. There is a huge unmet need for effective treatments in AN, which has high rates of morbidity and the highest mortality rate of any psychiatric disorder, yet a grave paucity of effective treatments. Viewing compulsivity as a transdiagnostic concept, seen in various manifestations across disorders, may help delineate the mechanisms responsible for the persistence of AN, and aid treatment development. We explore models of compulsivity that suggest dysfunction in cortico-striatal circuitry underpins compulsive behaviour, and consider evidence of aberrances in this circuitry across disorders. Excessive habit formation is considered as a mechanism by which initially rewarding weight loss behaviour in AN may become compulsive over time, and the complex balance between positive and negative reinforcement in this process is considered. The physiological effects of starvation in promoting compulsivity, positive reinforcement and habit formation are also discussed. Further research in AN may benefit from a focus on processes potentially underlying the development of compulsivity, such as aberrant reward processing and habit formation. We discuss the implications of a transdiagnostic perspective on compulsivity, and how it may contribute to the development of novel treatments for AN.

  18. Developmental considerations of anorexia nervosa and obesity.

    Bruch, H

    1981-06-01

    The differentiation of the distinct clinical syndrome of anorexia nervosa from atypical cases is based on the following distinguishing features: a relentless pursuit of thinness; an almost delusional disturbance of body image; an inability to correctly identify hunger from other bodily or tension states; a lack of an identity awareness; and a paralyzing sense of ineffectiveness. This sense of ineffectiveness, pervasive of all thought and action, is connected with the perception of the self as acting only in response to the demands of others and is camouflaged by negativism and defiance. The core developmental issues of being unable to experience the control over one's own body and of lacking the conviction of living one's own life are based on the severe deficits in autonomy and initiative, originating from the distortion and mislabeling of feelings, sensation and moods in early childhood. The treatment process focuses on evoking awareness in these patients of their impulses, feelings and needs as originating within themselves as an essential step in the development of a sense of competence and self-esteem.

  19. Neuroendocrine Consequences of Anorexia Nervosa in Adolescents

    Misra, Madhusmita; Klibanski, Anne

    2013-01-01

    Anorexia nervosa (AN) is a condition of severe undernutrition characterized by alterations in multiple neuroendocrine axes and peptides that signal or regulate energy intake. These alterations include a state of hypogonadotropic hypogonadism, a nutritionally acquired resistance to growth hormone (GH) with low IGF-1 levels, relative hypercortisolemia, low total T3 despite normal TSH, low levels of leptin and insulin, and elevated levels of ghrelin, peptide YY (PYY) and possibly adiponectin. Although many of these changes are adaptive to low weight, they can impact bone metabolism, body composition, reproductive function and statural growth. Low bone mass is characteristic of AN in both adolescent boys and girls. In girls, sites of trabecular bone are more likely to be affected than sites of cortical bone, whereas in boys with AN, sites of cortical bone are more commonly affected. Bone microarchitecture is also affected in adolescent girls with AN, with a decrease in trabecular thickness and bone trabecular volume, and an increase in trabecular separation. Important predictors of low bone density include nutritional factors, body composition, hypogonadism, low IGF-1, elevated cortisol and PYY levels, with possible contributions of low insulin. Weight gain is associated with a stabilization of bone density, although residual deficits persist in the short term, and in some cases, long term. PMID:19955768

  20. [Orthorexia nervosa. A new eating behavior disorder?].

    Catalina Zamora, M L; Bote Bonaechea, B; García Sánchez, F; Ríos Rial, B

    2005-01-01

    New eating behavior disorders such as bigorexia (muscle dysmorphia) and orthorexia are appearing in developed countries. These disorders have not been officially recognized so that they are not classified as independent entities. The term orthorexia comes from the Greek word orthos (straight, proper) and orexia (appetite). It is characterized by the pathological obsession for biologically pure food, which leads to important dietary restrictions. Orthorexic patients exclude foods from their diets that they consider to be impure because they have herbicides, pesticides or artificial substances and they worry in excess about the techniques and materials used in the food elaboration. This obsession leads to loss of social relationships and affective dissatisfactions which, in turn, favors obsessive concern about food. In orthorexia, that patient initially wants to improve his/her health, treat a disease or lose weight. Finally, the diet becomes the most important part of their lives. We present a clinical case that responds to the characteristics of orthorexia. The differential diagnosis with chronic delusional disorder, anorexia nervosa and obsessive-compulsive disorder is carried out.

  1. Visual body perception in anorexia nervosa.

    Urgesi, Cosimo; Fornasari, Livia; Perini, Laura; Canalaz, Francesca; Cremaschi, Silvana; Faleschini, Laura; Balestrieri, Matteo; Fabbro, Franco; Aglioti, Salvatore Maria; Brambilla, Paolo

    2012-05-01

    Disturbance of body perception is a central aspect of anorexia nervosa (AN) and several neuroimaging studies have documented structural and functional alterations of occipito-temporal cortices involved in visual body processing. However, it is unclear whether these perceptual deficits involve more basic aspects of others' body perception. A consecutive sample of 15 adolescent patients with AN were compared with a group of 15 age- and gender-matched controls in delayed matching to sample tasks requiring the visual discrimination of the form or of the action of others' body. Patients showed better visual discrimination performance than controls in detail-based processing of body forms but not of body actions, which positively correlated with their increased tendency to convert a signal of punishment into a signal of reinforcement (higher persistence scores). The paradoxical advantage of patients with AN in detail-based body processing may be associated to their tendency to routinely explore body parts as a consequence of their obsessive worries about body appearance.

  2. Volatile compounds formation in alcoholic fermentation from grapes collected at 2 maturation stages: influence of nitrogen compounds and grape variety.

    Martínez-Gil, Ana M; Garde-Cerdán, Teresa; Lorenzo, Cándida; Lara, José Félix; Pardo, Francisco; Salinas, M Rosario

    2012-01-01

    The aim of this work was to study the influence of nitrogen compounds on the formation of volatile compounds during the alcoholic fermentation carried out with 4 nonaromatic grape varieties collected at 2 different maturation stages. To do this, Monastrell, Merlot, Syrah, and Petit Verdot grapes were collected 1 wk before harvest and at harvest. Then, the musts were inoculated with the same Saccharomyces cerevisiae yeast strain and were fermented in the same winemaking conditions. Amino acids that showed the highest and the lowest concentration in the must were the same, regardless of the grape variety and maturation stage. Moreover, the consumption of amino acids during the fermentation increased with their concentration in the must. The formation of volatile compounds was not nitrogen composition dependent. However, the concentration of amino acids in the must from grapes collected 1 wk before harvest can be used as a parameter to estimate the concentration of esters in wines from grapes collected at harvest and therefore to have more information to know the grape oenological capacity. Application of principal components analysis (PCA) confirmed the possibility to estimate the concentration of esters in the wines with the concentration of nitrogen compounds in the must. © 2011 Institute of Food Technologists®

  3. Potassium uptake and redistribution in Cabernet Sauvignon and Syrah grape tissues and its relationship with grape quality parameters.

    Ramos, María Concepción; Romero, María Paz

    2017-08-01

    The present study investigated the potassium (K) levels in petiole and other grape tissues during ripening in Vitis vinifera Shiraz and Cabernet Sauvignon, grown in areas with differences in vigour, as well as with and without leaf thinning. Potassium levels in petiole, seeds, skin and flesh were related to grape pH, acidity, berry weight and total soluble solids. Differences in K levels in petiole were in accordance with the differences in soil K. Leaf thinning gave rise to higher K levels in petiole but, in grape tissues, the differences were not significant in all samplings, with greater differences at the end of the growing cycle. Potassium levels per berry in grape tissues increased from veraison to harvest, with K mainly accumulated in skins and, to a lesser extent, in flesh. Potassium levels in flesh positively correlated with pH and total soluble solids, whereas the correlation with titratable acidity was negative. Grape juice pH and total soluble solids positively correlated with K, whereas titratable acidity correlated negatively. Leaf thinning increased K levels in petiole, although differences in K levels in grape tissues were not significant. This suggests the need to consider the K berry concentration when aiming to optimise K fertilisation programmes. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

  4. [Anorexia nervosa in German medical literature 1900 to 1945. The role of anorexia nervosa in the origin of psychosomatic medicine].

    Habermas, T

    1992-01-01

    German-language publications on anorexia nervosa and Simmonds' disease from between 1900 and 1945 are reviewed in order to trace factors inherent in medical thinking which have mostly hindered German-language medicine in understanding anorexia nervosa. It is demonstrated that a) the few German-language physicians who did describe central and possible characteristics of a.n. (weight-phobia, overactivity, bulimia, self-induced vomiting) were enabled to do so by valuing detailed clinical description, also of psychic characteristics, and an interest in the neuroses; b) the concept of anorexia nervosa was better known than previously assumed, though largely misunderstood; c) typical diagnostic misinterpretations led to typical biases in the description of the syndrome; d) in Germany more than in other countries a.n. was confounded with Simmonds' disease; and e) in addition to other factors, one reason for this lay in the 'holistic' ideal of psychosomatic medicine in the 1930s.

  5. FILAMENTOUS FUNGI ON GRAPES IN CENTRAL SLOVAK WINE REGION

    Full Text Available The concern about filamentous fungi in the vineyards has traditionally been linked to spoilage of grapes due to fungal growth. The aims of this study were to monitor the mycobiota in Central Slovak wine region. The Central Slovak wine region is divided into seven different subregions. In this work we had ten grape samples from seven various wine growing subregions and eight different villages. Five of these samples were from white grape berries and five were from red grape berries. The sample nr. 7 was without chemical protection (interspecific variety and three samples (nr. 8, 9, 10 were from bio-production. In the samples were determined exogenous contamination (direct platting method and endogenous contamination (surface-disinfected grapes. The exogenous mycobiota was determined by the method that each sample of 50 grape berries without visible damage was direct plated on to a DRBC agar medium. In exogenous contamination was detected 17 different genera Alternaria, Arthrinium, Aspergillus, Bipolaris, Botrytis, Cladosporium, Cunninghamella, Epicoccum, Fusarium, Geotrichum, Chaetomium, Mucor, Penicillium, Phoma, Rhizopus, Sordaria, Trichoderma and group Mycelia sterilia in which we included all colony of filamentous fungi that after incubation did not create fruiting bodies necessary for identification to genera level. By the endogenous contamination was each sample of 50 grape berries was surface-disinfected with sodium hypochlorite solution (1% for 1 min, rinsed in sterile distilled water three times and plated onto a DRBC (Dichloran Rose Bengal Chloramphenicol medium, Merck, Germany. The plates were incubated at 25±1 ºC for 7 days in the dark. By the endogenous plating method was identified 15 different genera from all ten samples Alternaria, Arthrinium, Aspergillus, Botrytis, Cladosporium, Epicoccum, Fusarium, Geotrichum, Gelasinospora, Chaetomium, Mucor, Penicillium, Phoma, Rhizopus, Trichoderma and Mycelia sterilia.

    Recent studies suggest that altered function of higher-order appetitive neural circuitry may contribute to restricted eating in anorexia nervosa and overeating in bulimia nervosa. This study used sweet tastes to interrogate gustatory neurocircuitry involving the anterior insula and related regions that modulate sensory-interoceptive-reward signals in response to palatable foods. Participants who had recovered from anorexia nervosa and bulimia nervosa were studied to avoid confounding effects of altered nutritional state. Functional MRI measured brain response to repeated tastes of sucrose and sucralose to disentangle neural processing of caloric and noncaloric sweet tastes. Whole-brain functional analysis was constrained to anatomical regions of interest. Relative to matched comparison women (N=14), women recovered from anorexia nervosa (N=14) had significantly diminished and women recovered from bulimia nervosa (N=14) had significantly elevated hemodynamic response to tastes of sucrose in the right anterior insula. Anterior insula response to sucrose compared with sucralose was exaggerated in the recovered group (lower in women recovered from anorexia nervosa and higher in women recovered from bulimia nervosa). The anterior insula integrates sensory reward aspects of taste in the service of nutritional homeostasis. One possibility is that restricted eating and weight loss occur in anorexia nervosa because of a failure to accurately recognize hunger signals, whereas overeating in bulimia nervosa could represent an exaggerated perception of hunger signals. This response may reflect the altered calibration of signals related to sweet taste and the caloric content of food and may offer a pathway to novel and more effective treatments.

    González-Centeno, María Reyes; Jourdes, Michael; Femenia, Antoni; Simal, Susana; Rosselló, Carmen; Teissedre, Pierre-Louis

    2013-11-27

    A detailed assessment of the total phenolic and total tannin contents, the monomeric and oligomeric flavan-3-ol composition, the proanthocyanidin profile, and the antioxidant potential of the grape pomace byproducts (considered as a whole, both skins and seeds), derived from four white grape varieties (Vitis vinifera L.), was performed. Significant differences (p grape pomace byproducts were observed among the different grape varieties studied. For the first time in the literature, the particular flavan-3-ol composition of the four grape varieties investigated was described for the whole fraction of their grape pomace byproducts. The phenolic composition and antioxidant capacity of grape pomaces were compared to those of their corresponding stems. The global characterization of these white grape varieties provided a basis for an integrated exploitation of both winemaking byproducts as potential, inexpensive, and easily available sources of bioactive compounds for the pharmaceutical, cosmetic, and food industries.

  9. Neurobiology of anorexia and bulimia nervosa.

    Kaye, Walter

    2008-04-22

    Anorexia nervosa (AN) and bulimia nervosa (BN) are related disorders of unknown etiology that most commonly begin during adolescence in women. AN and BN have unique and puzzling symptoms, such as restricted eating or binge-purge behaviors, body image distortions, denial of emaciation, and resistance to treatment. These are often chronic and relapsing disorders, and AN has the highest death rate of any psychiatric disorder. The lack of understanding of the pathogenesis of this illness has hindered the development of effective interventions, particularly for AN. Individuals with AN and BN are consistently characterized by perfectionism, obsessive-compulsiveness, and dysphoric mood. Individuals with AN tend to have high constraint, constriction of affect and emotional expressiveness, ahendonia and asceticism, whereas individuals with BN tend to be more impulsive and sensation seeking. Such symptoms often begin in childhood, before the onset of an eating disorder, and persist after recovery, suggesting they are traits that create a vulnerability for developing an ED. There is growing acknowledgement that neurobiological vulnerabilities make a substantial contribution to the pathogenesis of AN and BN. Considerable evidence suggests that altered brain serotonin (5-HT) function contributes to dysregulation of appetite, mood, and impulse control in AN and BN. Brain imaging studies, using 5-HT specific ligands, show that disturbances of 5-HT function occur when people are ill, and persist after recovery from AN and BN. It is possible that a trait-related disturbance of 5-HT neuronal modulation predates the onset of AN and contributes to premorbid symptoms of anxiety, obsessionality, and inhibition. This dysphoric temperament may involve an inherent dysregulation of emotional and reward pathways which also mediate the hedonic aspects of feeding, thus making these individuals vulnerable to disturbed appetitive behaviors. Restricting food intake may become powerfully

  16. Directives in anorexia nervosa: use of the "Ulysses Agreement".

    Davidson, H; Birmingham, C L

    2003-09-01

    The course of anorexia nervosa frequently has episodes of exacerbation during which motivation and insight are reduced, cognition is impaired and treatment resistance is increased. Formalizing a directive to be used during these episodes when the patient has greater motivation and insight is one way of reducing treatment resistance. We describe a form of directive, called the "Ulysses Agreement".

  4. [Thyroid function in patients with anorexia nervosa and depression].

    Natori, Y; Yamaguchi, N; Koike, S; Aoyama, A; Tsuchibuchi, S; Kojyo, K; Demura, R

    1994-12-01

    Thyroid hormone levels were measured in 21 patients with anorexia nervosa, 15 patients with depression and 16 patients with severe depression and were compared with those in 53 normal subjects. In anorexia nervosa and severe depressed patients, serum T3, T4, fT3, fT4 and T3/T4 ratio showed significantly lower values than those in normal subjects. However there was no difference between depressed patients and normal subjects. The serum TSH levels were within normal range in all of the studied subjects. Thus, thyroid hormone levels in severe depressed patients were similar to those in anorexia nervosa and the changes were inversely related to disease conditions. The supplementation of thyroid hormones to antidepressant relieved clinical symptoms in some of the severe depressed patients. These results suggested that the changes in thyroid hormone levels in anorexia nervosa and severe depression were mainly due to impaired conversion of T4 to T3 by increased cortisol secretion through emotional stress.

    Chiarioni, G; Bassotti, G; Monsignori, A; Menegotti, M; Salandini, L; Di Matteo, G; Vantini, I; Whitehead, W E

    2000-10-01

    To evaluate anorectal and colonic function in a group of patients with anorexia nervosa complaining of chronic constipation. Twelve women (age range, 19-29 years) meeting the criteria for anorexia nervosa and complaining of chronic constipation were recruited for the study. A group of 12 healthy women served as controls. Colonic transit time was measured by a radiopaque marker technique. Anorectal manometry and a test of rectal sensation were carried out with use of standard techniques to measure pelvic floor dysfunction. A subgroup of 8 patients was retested after an adequate refeeding program was completed. Eight (66.7%) of 12 patients with anorexia nervosa had slow colonic transit times, while 5 (41.7%) had pelvic floor dysfunction. Colonic transit time normalized in the 8 patients who completed the 4-week refeeding program. However, pelvic floor dysfunction did not normalize in these patients. Patients with anorexia nervosa who complain of constipation have anorectal motor abnormalities. Delayed colonic transit time is probably due to abnormal eating behavior.

    2017-04-30

    Although schizophrenia and anorexia nervosa are seemingly very distinct psychiatric disorders, their symptoms are connected by various types of relationships. The present article reviews the literature and recapitulates the views of various authors on the links between these two disorders. Symptoms of anorexia may 1) precede the onset of psychosis; 2) evolve in its active phase or more rarely manifest in remission; and, conversely, 3) psychotic symptoms may occur transiently in the course of anorexia nervosa. When anorexia precedes the manifestation of psychosis, symptoms of anorexia can be treated as a component of the prodromal phase of schizophrenia. Another possibility of co-existence of a psychosis (e.g., schizophrenia) with anorexia is when the eating disorder syndrome manifests at the same time as the full-blown psychotic syndrome. In such cases, when the symptoms of the two disorders occur simultaneously, it is often difficult to say whether the patient is suffering from schizophrenia, in the course of which anorexia has arisen secondary to psychotic symptoms or whether he/she is suffering from anorexia during which he/she has developed psychotic symptoms, usually thematically associated with eating. Studies published so far, mainly case reports, point to the complex nature of the interrelationships between schizophrenia and anorexia nervosa. Further research is needed to conclusively explain the relationships between psychotic disorders and anorexia nervosa, which would allow physicians to use more effective methods of treatment in this group of patients.

  6. Prevalence of orthorexia nervosa among Turkish performance artists.

    Aksoydan, E; Camci, N

    2009-03-01

    The aim of the study was to determine the prevalence of orthorexia nervosa among the performance artists in the State Opera and Ballet and in the Bilkent University Symphony Orchestra. The study population consisted of 39 men and 55 women for a total of 94 artists with mean age of 33 years. The ORTO-15 test was used to determine the prevalence of orthorexia nervosa. Those subjects who scored below 40 in the ORTO-15 test were classified as having orthorexia nervosa. Mean score of the participants in the ORTO-15 test was 37.9+/-4.46. A total of 56.4% of the artists involved in the research scored below 40 in the ORTO-15 test. While the highest prevalence of orthorexia nervosa was recorded among opera singers (81.8%), it was 32.1% among ballet dancers and 36.4% among symphony orchestra musicians. The differences between the three groups were statistically significant. No difference was noted between mean ORTO-15 score by baseline characteristics as gender, age, educational level, work experience, body mass index, smoking and alcohol consumption. The research group have a higher socio-economic and education level than the majority of the general public in Turkey. Additionally, being an artist in Turkey means being a role model for the general public both in terms one's physical appearance and lifestyle. These may be the reason why artists are more sensitive to this issue.

    Lackner, N; Unterrainer, H F; Skliris, D; Wood, G; Dunitz-Scheer, M; Wallner-Liebmann, S J; Scheer, P J Z; Neuper, C

    2016-02-01

    Anorexia nervosa has been related to alterations in brain activity in terms of hyperactive EEG patterns. This case report illustrates the principles and results of a five-week neurofeedback treatment in a 29-year-old woman suffering from anorexia nervosa. A neurofeedback protocol to enhance alpha activity (8 - 12 Hz) was developed and conducted additionally to the standardized treatment for eating disorders in training sessions twice a week. Pre- and post-test measurements included resting state EEG measurements and a psychological test battery. The results show improvements from pre- to post-test in eating disorder psychopathology including psychological wellbeing, emotional competence, and eating behavior traits. In addition, a decrease in theta power (4 - 7 Hz), a well-known trait marker of anorexia nervosa, was measured. However, our data should be interpreted with caution because this is a single case study. Nevertheless, this report documents the practicability and method of neurofeedback as treatment adjunct in eating disorders from the clinical perspective. Although the use of neurofeedback in the treatment of anorexia nervosa is recommended in literature, empirical studies are still lacking. Randomized controlled trials to evaluate short- and long-term effects of neurofeedback are needed. © Georg Thieme Verlag KG Stuttgart · New York.

  8. Gait analysis in anorexia and bulimia nervosa.

    Anorexia (AN) and Bulimia Nervosa (BN) are two common eating disorders, which appear to share some reduced motor capacities, such as a reduced balance. The presence and the extent of other motor disorders have not been investigated in a comprehensive way. The aim of this study was to quantify gait pattern in AN and BN individuals in order to ascertain possible differences from the normality range and provide novel data for developing some evidence-based rehabilitation strategies. Nineteen AN patients (age 30.16+9.73) and 20 BN patients (age 26.8+8.41) were assessed with quantitative 3D computerized Gait Analysis. Results were compared with a group of healthy controls (CG; 30.7+5.6). AN and BN patients were characterized by different gait strategies compared to CG. Spatio-temporal parameters indicated shorter step length, with AN showing the shortest values. AN walked slower than BN and CG. As for kinematics, AN and BN showed a nonphysiologic pattern at pelvis and hip level on the sagittal and frontal plane, with BN yielding the most abnormal values. Both AN and BN patients were characterized by high ankle plantar flexion capacity at toe-off when compared to CG. As for ankle kinetics, both AN and BN showed physiologic patterns. Stiffness at hip level was close to CG in both pathologic groups; at the ankle level, stiffness was significantly decreased in both groups, with AN displaying lower values. Both AN and BN were characterized by an altered gait pattern compared to CG. Biomechanical differences were evident mainly at pelvis and hip level. Loss of lean mass may lead to musculoskeletal adaptation, ultimately causing alterations in the gait pattern.

    The wine industry is well known for its production of a large amount of wastes and by-products. Among them, unripe grapes from thinning operations are an undervalued by-product. Grapes are an interesting source of natural antioxidants such as flavonoids, non-flavonoids and stilbenes. A potential strategy to exploit unripe grapes was investigated in this study. Juice from unripe grapes, v. Sangiovese, was obtained by an innovative technique of solid-liquid extraction without the use of solvent...

  11. Molecular bases of anorexia nervosa, bulimia nervosa and binge eating disorder: shedding light on the darkness.

    Cuesto, Germán; Everaerts, Claude; León, Leticia G; Acebes, Angel

    2017-12-01

    Eating-disorders (EDs) consequences to human health are devastating, involving social, mental, emotional, physical and life-threatening aspects, concluding on impairment and death in cases of extreme anorexia nervosa. It also implies that people suffering an ED need to find psychiatric and psychological help as soon as possible to achieve a fully physical and emotional recovery. Unfortunately, to date, there is a crucial lack of efficient clinical treatment to these disorders. In this review, we present an overview concerning the actual pharmacological and psychological treatments, the knowledge of cells, circuits, neuropeptides, neuromodulators and hormones in the human brain- and other organs- underlying these disorders, the studies in animal models and, finally, the genetic approaches devoted to face this challenge. We will also discuss the need for new perspectives, avenues and strategies to be developed in order to pave the way to novel and more efficient therapeutics.

  12. State self-esteem ratings in women with bulimia nervosa and bulimia nervosa in remission.

    Daley, Karen A; Jimerson, David C; Heatherton, Todd F; Metzger, Eran D; Wolfe, Barbara E

    2008-03-01

    Bulimia nervosa (BN) is associated with low self-esteem. This study was designed to assess whether low self-esteem persists in nondepressed individuals who have recovered from BN (BN-R). Study groups included BN (n = 22), BN-R (n = 20), and healthy controls (n = 42). Participants were medication-free, and none met criteria for current major depression. Assessment instruments included the State Self-Esteem Scale (SSES), a self-rating scale designed to measure state-related changes in self-esteem. Consistent with previous reports, SSES scores for BN were lower than for controls (p p p p low self-esteem following recovery from BN. Follow-up studies are needed to assess whether low self-esteem contributes to recurrent dieting and risk for relapse.

  13. Ultrasound-assisted extraction of amino acids from grapes.

    Carrera, Ceferino; Ruiz-Rodríguez, Ana; Palma, Miguel; Barroso, Carmelo G

    2015-01-01

    Recent cultivar techniques on vineyards can have a marked influence on the final nitrogen content of grapes, specifically individual amino acid contents. Furthermore, individual amino acid contents in grapes are related to the final aromatic composition of wines. A new ultrasound-assisted method for the extraction of amino acids from grapes has been developed. Several extraction variables, including solvent (water/ethanol mixtures), solvent pH (2-7), temperature (10-70°C), ultrasonic power (20-70%) and ultrasonic frequency (0.2-1.0s(-)(1)), were optimized to guarantee full recovery of the amino acids from grapes. An experimental design was employed to optimize the extraction parameters. The surface response methodology was used to evaluate the effects of the extraction variables. The analytical properties of the new method were established, including limit of detection (average value 1.4mmolkg(-)(1)), limit of quantification (average value 2.6mmolkg(-)(1)), repeatability (average RSD=12.9%) and reproducibility (average RSD=15.7%). Finally, the new method was applied to three cultivars of white grape throughout the ripening period. Copyright © 2014 Elsevier B.V. All rights reserved.

  14. Grape berry bacterial inhibition by different copper fungicides

    Martins Guilherme

    2016-01-01

    Full Text Available Copper fungicides are widely used in viticulture. Due to its large spectrum of action, copper provides an efficient control over a great number of vine pathogens. Previous studies showed that, high levels of cupric residues can impact grape-berry microbiota, in terms of the size and population structure, reducing the diversity and the abundance. Due to the importance of grape-berry bacterial in crop health, and the potential impact of copper fungicides over the microbiota, we determined Minimum Inhibitory Concentration (MIC of different copper formulations for bacterial species isolated from grape berries. We study the Minimum Inhibitory Concentration (MIC of different copper formulations (copper sulphate (CuSO4 pure, Bordeaux mixture (CuSO4 + Ca(OH2, copper oxide (Cu2O, copper hydroxide (Cu(OH2 over 92 bacterial strains isolated from grape berries in different stages of the ripening process. The results of MIC measurements revealed that the different copper formulations have a variable inhibitory effect and among the different isolates, some species are the most resistant to all copper formulations than others. This study confirm that usage of cupric phytosanitary products should be reasonable independently of the farming system; they also provide evidence of the importance of the choice of which copper formulations are to be used regarding their impact on the grape berry bacterial microbiota.

  15. Enhanced antioxidant activity of polyolefin films integrated with grape tannins.

    Olejar, Kenneth J; Ray, Sudip; Kilmartin, Paul A

    2016-06-01

    A natural antioxidant derived from an agro-waste of the wine industry, grape tannin, was incorporated by melt blending into three different polyolefins (high-density polyethylene, linear low-density polyethylene and polypropylene) to introduce antioxidant functionality. Significant antioxidant activity was observed at 1% tannin inclusion in all polymer blends. The antioxidant activity was observed to increase steadily with a greater concentration of grape tannins, the highest increases being seen with polypropylene. The mechanical and thermal properties of the polymer films following antioxidant incorporation were minimally altered with up to 3% grape tannins. All of the polyolefin-grape tannin films successfully passed the leachability test following USP661 standard protocol. Superior antioxidant activity was established in polyolefin thin films by utilization of a bulk grape extract obtained from winery waste. Significant increases in antioxidant activity were seen with 1% extract inclusion. This not only demonstrates the potential for food packaging applications of the polyolefin blends, but also valorizes the agro-waste. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

    Gupta, Sumit; Padole, Rupali; Variyar, Prasad S.; Sharma, Arun

    2015-01-01

    Grapes (Var. Shiraz and Cabernet) were subjected to radiation processing (up to 2 kGy) and wines were prepared and matured (4 months, 15 °C). The wines were analyzed for chromatic characteristics, total anthocyanin (TA), phenolic (TP) and total antioxidant (TAC) content. Aroma of wines was analyzed by GC/MS and sensory analysis was carried out using descriptive analysis. TA, TP and TAC were 77, 31 and 37 percent higher for irradiated (1500 Gy) Cabernet wines, while irradiated Shiraz wines demonstrated 47, 18 and 19 percent higher TA, TP and TAC, respectively. HPLC-DAD analysis revealed that radiation processing of grapes resulted in increased extraction of phenolic constituents in wine with no qualitative changes. No major radiation induced changes were observed in aroma constituents of wine. Sensory analysis revealed that 1500 Gy irradiated samples had higher fruity and berry notes. Thus, radiation processing of grapes resulted in wines with improved organoleptic and antioxidant properties. - Highlights: • Grapes were subjected to radiation processing before wine making. • Wines from irradiated grapes had higher antioxidant and phenolics compared to control. • HPLC analysis confirmed improved extraction of phenolics due to radiation processing. • Aroma profile and sensory quality of control and irradiated wines were similar

    To characterize exercise behaviors among adolescents with anorexia nervosa (AN), atypical AN, or bulimia nervosa (BN), and determine associations between exercise and medical risk. Cross-sectional electronic medical records of all patients evaluated by the Eating Disorder Program at Stanford between January 1997 and February 2011 were retrospectively reviewed. 1,083 subjects (961 females, 122 males; mean age 15.6) met eligibility criteria. Most patients (89.7%) reported exercise (mean 7.0 h per week over mean 5.4 days per week) prior to presentation. Running (49.9%), calisthenics (40.7%), walking (23.4%), soccer (20.9%), and swimming (18.2%) were the most common exercises; a majority (60.6%) reported team sport participation. Males were less likely to report team exercise (p = .005). Bradycardia (heart rate <50) at presentation was associated with team sport participation (adjusted odds ratio [AOR] 1.66, 95% confidence interval [CI] 1.02-2.72) and hours of exercise per week (AOR 1.05, 95% CI 1.02-1.09), controlling for diagnosis, sex, age, duration of illness, rate of weight loss, and percent median body mass index (%mBMI). Adolescents with AN, atypical AN, and BN reported high levels of exercise. Females reported more team sport participation. Greater exercise frequency and team sport participation were associated with bradycardia. Further studies assessing the relationship between exercise and bradycardia may help inform the medical management of adolescents with these eating disorders who are more physically active. © 2017 Wiley Periodicals, Inc.

Orsola Malpighi Hospital, Bologna, Italy Background: Berberis aristata, because of its berberine content, and Monascus purpureus fermented rice, because of the presence of monacolins (naturally derived statins, are widely investigated food-grade ingredients used to formulate cholesterol-lowering supplements. Although they are extensively used, berberine is poorly absorbed and monacolins are poorly chemically characterized, not standardized, and possibly contaminated with toxic compounds. Silymarin is reported to enhance berberine absorption, while Monakopure™-K20 (MK-20 is a highly standardized red yeast rice containing monacolins K and KA in the ratio of 1:1 but not secondary monacolins, dehydromonacolins, or citrinin.Aim: The effects of a cholesterol-lowering supplement (Berberol®K containing berberine, silymarin, and MK-20 (BSM in patients with dyslipidemia were clinically analyzed.Methods: The clinical role of BSM in naïve and in statin-intolerant patients was retrospectively evaluated and the effects observed were compared with those obtained in patients without treatment or treated with lovastatin.Results: Total cholesterol, low density lipoprotein, and triglyceride levels were approximately 4%, 6%, and 11% lower, respectively, and the creatine phosphokinase increase was reduced in patients treated with BSM compared to those treated with lovastatin. Similar results were also obtained in statin-intolerant subjects where BSM was administered as add-on therapy to ezetimibe or fenofibrate. Conclusion: BSM is a food supplement

    Cancer is a multifactorial disease and hence can be effectively overcome by a multi-constituently therapeutic strategy. Medicinal plant extracts represent a perfect example of such stratagem. However, minimal studies have been done till date that portray the effect of extraction techniques on the phyto-constituent profile of plant extracts and its impact on anticancer activity. In the present study, we have evaluated the anticancer potential of methanolic extracts of Berberis aristata root and Azadirachta indica seeds prepared by various extraction techniques in human osteosarcoma (HOS) cells. Soxhlation extract of B. aristata (BAM-SX) and sonication extract of A. indica (AIM-SO) were most effective in inducing apoptosis in parental drug sensitive, as well as resistant cell type developed by repeated drug exposure. Generation of reactive oxygen species and cell cycle arrest preceded caspase-mediated apoptosis in HOS cells. Interestingly, inhibition of autophagy enhanced cell death suggesting the cytoprotective role of autophagy. Combination studies of different methanolic extracts of BAM and AIM were performed, among which, the combination of BAM-SO and AIM-SO (BAAISO) was found to show synergism (IC50 10.27 µg/ml) followed by combination of BAM-MC and AIM-MC (BAAIMC) with respect to other combinations in the ratio of 1:1. BAAISO also showed synergism when it was added to cisplatin-resistant HOS cells (HCR). Chromatographic profiling of BAM-SX and AIM-SO by high performance thin layer chromatography resulted in identification of berberine (Rf 0.55), palmitine (Rf 0.50) in BAM-SX and azadirachtin A (Rf 0.36), azadirachtin B (Rf 0.56), nimbin (Rf 0.80), and nimbolide (Rf 0.43) in AIM-SO. The cytotoxic sensitivity obtained can be attributed to the above compounds. Our results highlight the importance of extraction technique and subsequent mechanism of action of multi-constituential B. aristata and A. indica against both sensitive and drug refractory HOS cells.

  2. Anorexia nervosa versus hyperinsulinism: therapeutic effects of neuropharmacological manipulation

    Lechin, Fuad; van der Dijs, Bertha; Pardey-Maldonado, Betty; Baez, Scarlet; Lechin, Marcel E

    2011-01-01

    Background: We have demonstrated that anorexia nervosa is underpinned by overwhelming adrenal sympathetic activity which abolishes the neural sympathetic branch of the peripheral autonomic nervous system. This physiological disorder is responsible for gastrointestinal hypomotility, hyperglycemia, raised systolic blood pressure, raised heart rate, and other neuroendocrine disorders. Therefore, we prescribed neuropharmacological therapy to reverse this central and autonomic nervous system disorder, in order to normalize the clinical and neuroendocrine profile. Methods: The study included 22 female patients with anorexia nervosa (10 restricted type, 12 binge-eating type) who received three months of treatment with amantadine 100 mg/day. We measured blood pressure, heart rate, and circulating neurotransmitters, (noradrenaline, adrenaline, dopamine, platelet serotonin, free plasma serotonin) during supine resting, one minute of orthostasis, and a five-minute exercise test before and after one, two, and three months of treatment with amantadine, a drug which abrogates adrenal sympathetic activity by acting at the C1(Ad) medullary nuclei responsible for this branch of the peripheral sympathetic activity. Results: We found the amantadine abolished symptoms of anorexia nervosa from the first oral dose onwards. Normalization of autonomic and cardiovascular parameters was demonstrated within the early days of therapy. Abrupt and sustained increases in the plasma noradrenaline:adrenaline ratio and disappearance of abnormal plasma glucose elevation were registered throughout the three-month duration of the trial. Significant and sustained increases in body weight were documented in all cases. No relapses were observed. Conclusion: We have confirmed our previously published findings showing that the anorexia nervosa syndrome depends on the hypomotility of the gastrointestinal tract plus hyperglycemia, both of which are triggered by adrenal sympathetic hyperactivity. The above

  5. Phenolic Compounds and Antioxidant Activity in Grape Juices: A Chemical and Sensory View

    Fernanda Cosme

    2018-03-01

    Full Text Available The search for food products that promote health has grown over the years. Phenolic compounds present in grapes and in their derivatives, such as grape juices, represent today a broad area of research, given the benefits that they have on the human health. Grape juice can be produced from any grape variety once it has attained appropriate maturity. However, only in traditional wine producing regions, grape juices are produced from Vitis vinifera grape varieties. For example, Brazilian grape juices are essentially produced from Vitis labrusca grape varieties, known as American or hybrid, as they preserve their characteristics such as the natural flavour after pasteurisation. Grapes are one of the richest sources of phenolic compounds among fruits. Therefore, grape juices have been broadly studied due to their composition in phenolic compounds and their potential beneficial effects on human health, specifically the ability to prevent various diseases associated with oxidative stress, including cancers, cardiovascular and neurodegenerative diseases. Therefore, this review will address grape juices phenolic composition, with a special focus on the potential beneficial effects on human health and on the grape juice sensory impact.

  6. Position of the American Dietetic Association: Nutrition intervention in the treatment of anorexia nervosa, bulimia nervosa, and other eating disorders.

    2006-12-01

    It is the position of the American Dietetic Association that nutrition intervention, including nutritional counseling, by a registered dietitian (RD) is an essential component of the team treatment of patients with anorexia nervosa, bulimia nervosa, and other eating disorders during assessment and treatment across the continuum of care. Diagnostic criteria for eating disorders provide important guidelines for identification and treatment. However, it is thought that a continuum of disordered eating may exist that ranges from persistent dieting to subthreshold conditions and then to defined eating disorders, which include anorexia nervosa, bulimia nervosa, and binge eating disorder. Understanding the complexities of eating disorders, such as influencing factors, comorbid illness, medical and psychological complications, and boundary issues, is critical in the effective treatment of eating disorders. The nature of eating disorders requires a collaborative approach by an interdisciplinary team of psychological, nutritional, and medical specialists. The RD is an integral member of the treatment team and is uniquely qualified to provide medical nutrition therapy for the normalization of eating patterns and nutritional status. RDs provide nutritional counseling, recognize clinical signs related to eating disorders, and assist with medical monitoring while cognizant of psychotherapy and pharmacotherapy that are cornerstones of eating disorder treatment. Specialized resources are available for RDs to advance their level of expertise in the field of eating disorders. Further efforts with evidenced-based research must continue for improved treatment outcomes related to eating disorders along with identification of effective primary and secondary interventions.

  7. Increased P-wave dispersion a risk for atrial fibrillation in adolescents with anorexia nervosa.

    2016-01-01

    Studies have shown that a prolonged P-wave dispersion is a risk factor for the development of atrial fibrillation. The aim of this study was to evaluate P-wave dispersion in adolescents with anorexia nervosa at diagnosis. We evaluated electrocardiographic findings, particularly the P-wave dispersion, at initial assessment in 47 adolescents with anorexia nervosa. Comparison of P-wave dispersion between adolescents with anorexia nervosa and controls showed a statistically significant higher P-wave dispersion in patients with anorexia nervosa (72 ± 16.3 msec) when compared to the control group (43.8 ± 9.5 msec). Percent of body weight lost, lower body mass index, and higher weight loss rate in the patients with anorexia nervosa had no effect on P-wave dispersion. Due to the fact that anorexia nervosa has a high mortality rate we believe that cardiac pathologies such as atrial fibrillation must also be considered in the medical evaluation.

  8. An Overview of Stress-Induced Resveratrol Synthesis in Grapes: Perspectives for Resveratrol-Enriched Grape Products

    Mohidul Hasan

    2017-02-01

    Full Text Available Resveratrol is the most important stilbene phytoalexin synthesized naturally or induced in plants, as a part of their defense mechanism. Grapes and their derivative products, including juice and wine, are the most important natural sources of resveratrol, consisting of notably higher amounts than other natural sources like peanuts. Consumption of red wine with its presence of resveratrol explained the “French Paradox”. Hence, the demand of resveratrol from grapes is increasing. Moreover, as a natural source of resveratrol, grapes became very important in the nutraceutical industry for their benefits to human health. The accumulation of resveratrol in grape skin, juice, and wine has been found to be induced by the external stimuli: microbial infection, ultrasonication (US treatment, light-emitting diode (LED, ultra violet (UV irradiation, elicitors or signaling compounds, macronutrients, and fungicides. Phenylalanine ammonia lyase, cinnamate-4-hydroxylase, coumaroyl-CoA ligase, and stilbene synthase play a key role in the synthesis of resveratrol. The up-regulation of those genes have the positive relationship with the elicited accumulation of resveratrol. In this review, we encapsulate the effect of different external stimuli (biotic and abiotic stresses or signaling compounds in order to obtain the maximum accumulation of resveratrol in grape skin, leaves, juice, wine, and cell cultures.

    2016-01-01

    Full Text Available In 2014, the National Wine Agency of the Republic of Georgia initiated a three-year “Research Project for the study of Georgian Grapes and Wine Culture. Through collaborative research by Georgian and foreign institutions and researchers, the project aims to: stimulate research of Georgian viticulture and viniculture, through the lens of the country with the earliest tradition of grape domestication and winemaking; and to reconstruct the continuous development of viticulture and wine culture through time. The project advances the study of grape and wine culture by utilizing a multidisciplinary approach, including: archaeology, history, ethnography, molecular genetics, biomolecular archaeology, palaeobotany, ampelography, enology, climatology and other scientific fields. These studies are diachronic in their approach, beginning with the oldest Neolithic civilizations, to present day, creating a holistic understanding of the continuity and complexity of Georgian Wine Culture to help popularize Georgian Wine throughout the global wine market.

  15. Evolution of Analysis of Polyhenols from Grapes, Wines, and Extracts

    Pierre-Louis Teissedre

    2013-01-01

    Full Text Available Grape and wine phenolics are structurally diverse, from simple molecules to oligomers and polymers usually designated as tannins. They have an important impact on the organoleptic properties of wines, that’s why their analysis and quantification are of primordial importance. The extraction of phenolics from grapes and from wines is the first step involved in the analysis. Then, several analytical methods have been developed for the determination of total content of phenolic, while chromatographic and spectrophotometric analyses are continuously improved in order to achieve adequate separation of phenolic molecules, their subsequent identification and quantification. This review provides a summary of evolution of analysis of polyphenols from grapes, wines and extracts.

  16. Methoxypyrazines biosynthesis and metabolism in grape: A review.

    Lei, Yujuan; Xie, Sha; Guan, Xueqiang; Song, Changzheng; Zhang, Zhenwen; Meng, Jiangfei

    2018-04-15

    This review summarizes research on the discovery, biosynthesis, accumulation, transport, and metabolism of 3-alkyl-2-methoxypyrazines (MPs) in grape. The MPs are a family of potent volatile compounds distributed throughout biological kingdoms. These compounds impart herbaceous/green/vegetal sensory attributes to certain varieties of wine. Generally, high levels of MPs in wine are derived mainly from the corresponding grapes. Although two pathways for MPs biosynthesis have been proposed, only the final step and the enzymes that catalyze it has been confirmed in grape, and the metabolic intermediates and key enzymes involved in other steps are still unknown. The limited understanding of MPs metabolism has restricted research on these compounds, and some empirical results cannot be explained by the current knowledge of MPs metabolism. This review provides insights into research on MPs biosynthesis and metabolism, and proposes directions for further research on this important class of flavour/odour compounds.

  17. Diagnosed Anxiety Disorders and the Risk of Subsequent Anorexia Nervosa: A Danish Population Register Study.

    Meier, Sandra M; Bulik, Cynthia M; Thornton, Laura M; Mattheisen, Manuel; Mortensen, Preben B; Petersen, Liselotte

    2015-11-01

    Anxiety disorders and anorexia nervosa are frequently acknowledged to be highly comorbid conditions, but still, little is known about the clinical and aetiological cohesion of specific anxiety diagnoses and anorexia nervosa. Using the comprehensive Danish population registers, we aimed to determine the risk of anorexia nervosa in patients with register-detected severe anxiety disorders. We also explored whether parental psychopathology was associated with offspring's anorexia nervosa. Anxiety disorders increased the risk of subsequent anorexia nervosa, with the highest risk observed in obsessive-compulsive disorder. Especially, male anxiety patients were at an increased risk for anorexia nervosa. Furthermore, an increased risk was observed in offspring of fathers with panic disorder. A diagnosis of an anxiety disorder, specifically obsessive-compulsive disorder, constitutes a risk factor for subsequent diagnosis of anorexia nervosa. These observations support the notion that anxiety disorders and anorexia nervosa share etiological mechanisms and/or that anxiety represents one developmental pathway to anorexia nervosa.

  18. Medical complications of anorexia nervosa and their treatments: an update on some critical aspects.

    Brown, Carrie; Mehler, Philip S

    2015-12-01

    Anorexia nervosa has the highest mortality rate of any psychiatric disorder. Many of the deaths are attributable to medical complications which arise as the malnutrition and weight loss worsens. Every body system may be adversely affected by anorexia nervosa. Yet, remarkably, most of the medical complications of anorexia nervosa are treatable and reversible with optimal medical care, as part of a multidisciplinary team who are often involved in the care of these patients. Herein, we will describe the medical complications of anorexia nervosa and their treatments.

  19. Grey matter correlates of autistic traits in women with anorexia nervosa.

    Björnsdotter, Malin; Davidovic, Monika; Karjalainen, Louise; Starck, Göran; Olausson, Håkan; Wentz, Elisabet

    2018-03-01

    Patients with anorexia nervosa exhibit higher levels of behaviours typically associated with autism-spectrum disorder (ASD), but the neural basis is unclear. We sought to determine whether elevated autistic traits in women with anorexia nervosa may be reflected in cortical morphology. We used voxel-based morphometry (VBM) to examine regional grey matter volumes in high-resolution MRI structural brain scans in women with anorexia nervosa and matched healthy controls. The Autism-spectrum Quotient (AQ) scale was used to assess autistic traits. Women with anorexia nervosa ( n = 25) had higher AQ scores and lower bilateral superior temporal sulcus (STS) grey matter volumes than the control group ( n = 25). The AQ scores correlated negatively with average left STS grey matter volume in women with anorexia nervosa. We did not control for cognitive ability and examined only women with ongoing anorexia nervosa. Elevated autistic traits in women with anorexia nervosa are associated with morphometric alterations of brain areas linked to social cognition. This finding provides neurobiological support for the behavioural link between anorexia nervosa and ASD and emphasizes the importance of recognizing autistic traits in preventing and treating anorexia nervosa.

We sought to determine whether elevated autistic traits in women with anorexia nervosa may be reflected in cortical morphology. Methods We used voxel-based morphometry (VBM) to examine regional grey matter volumes in high-resolution MRI structural brain scans in women with anorexia nervosa and matched healthy controls. The Autism-spectrum Quotient (AQ) scale was used to assess autistic traits. Results Women with anorexia nervosa (n = 25) had higher AQ scores and lower bilateral superior temporal sulcus (STS) grey matter volumes than the control group (n = 25). The AQ scores correlated negatively with average left STS grey matter volume in women with anorexia nervosa. Limitations We did not control for cognitive ability and examined only women with ongoing anorexia nervosa. Conclusion Elevated autistic traits in women with anorexia nervosa are associated with morphometric alterations of brain areas linked to social cognition. This finding provides neurobiological support for the behavioural link between anorexia nervosa and ASD and emphasizes the importance of recognizing autistic traits in preventing and treating anorexia nervosa.

    1992-06-01

    Full Text Available Studies on the lipid constituents of grape seeds, produced as by-product from white grape processing, were carried out. Gas liquid chromatography was used to determine the composition of fatty acid methyl esters and sterol silyl derivatives of the oil. The oil was found to contain appreciable amount of unsaturated fatty acids, namely, oleic and linoleic acids, however, linolenic acid was not detected. Saturated fatty acids, namely, palmitic and stearic were found to be present in reasonable amounts. Myristic, palmitoleic, eicosanoic and eicosadienoic acids were detected as minor components. Isofucosterol was found among the other sterol constituents namely, campesterol, stigmasterol and beta-sitosterol. HPLC analysis of the oil for determination of tocopherols, showed the presence of alpha-and gamma-tocotrienols, and alpha-and gamma-tocopherols to the extent of 53.2, 28.6, 16,4 and 1,8% respectively. The total tocopherols content of the oil was 470 ppm. The defatted meal of grape seeds was found to contain 24,6% protein which contained large proportions of all the essential amino acids as determined by amino acid analyzer.

    Purpose To investigate the composition, cross-sectional area (CSA), and hormonal correlates of different fat depots in women with anorexia nervosa (AN) and control subjects with normal weights to find out whether patients with AN have lower fat CSA but higher attenuation than did control subjects and whether these changes may be mediated by gonadal steroids, cortisol, and thyroid hormones. Materials and Methods This study was institutional review board approved and HIPAA compliant. Written informed consent was obtained. Forty premenopausal women with AN and 40 normal-weight women of comparable age (mean age ± standard deviation, 26 years ± 5) were studied. All individuals underwent computed tomography of the abdomen and thigh with a calibration phantom. Abdominal subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), thigh SAT, and thigh intermuscular adipose tissue CSA and attenuation were quantified. Serum estradiol, thyroid hormones, and urinary free cortisol levels were assessed. Variables were compared by using analysis of variance. Associations were examined by using linear regression analysis. Results Women with AN had higher fat attenuation than did control subjects (−100.1 to −46.7 HU vs −117.6 to −61.8 HU, P < .0001), despite lower fat CSA (2.0–62.8 cm2 vs 5.5–185.9 cm2, P < .0001). VAT attenuation but not CSA was inversely associated with lowest prior lifetime body mass index in AN (r = −0.71, P = .006). Serum estradiol levels were inversely associated with fat attenuation (r = −0.34 to −0.61, P = .03 to <.0001) and were positively associated with fat CSA of all compartments (r = 0.42–0.64, P = .007 to <.0001). Thyroxine levels and urinary free cortisol levels were positively associated with thigh SAT attenuation (r = 0.64 [P = .006] and r = 0.68 [P = .0004], respectively) and were inversely associated with abdominal SAT and VAT CSA (r = −0.44 to −0.58, P = .04 to .02). Conclusion Women with AN have differences in fat

This physiological disorder is responsible for gastrointestinal hypomotility, hyperglycemia, raised systolic blood pressure, raised heart rate, and other neuroendocrine disorders. Therefore, we prescribed neuropharmacological therapy to reverse this central and autonomic nervous system disorder, in order to normalize the clinical and neuroendocrine profile.Methods: The study included 22 female patients with anorexia nervosa (10 restricted type, 12 binge-eating type who received three months of treatment with amantadine 100 mg/day. We measured blood pressure, heart rate, and circulating neurotransmitters, (noradrenaline, adrenaline, dopamine, platelet serotonin, free plasma serotonin during supine resting, one minute of orthostasis, and a five-minute exercise test before and after one, two, and three months of treatment with amantadine, a drug which abrogates adrenal sympathetic activity by acting at the C1(Ad medullary nuclei responsible for this branch of the peripheral sympathetic activity.Results: We found the amantadine abolished symptoms of anorexia nervosa from the first oral dose onwards. Normalization of autonomic and cardiovascular parameters was demonstrated within the early days of therapy. Abrupt and sustained increases in the plasma noradrenaline

    Anorexia nervosa is a complex psychiatric illness that can lead to severe physical complications. This work aimed to study the approach taken by the child psychiatry service of Razi hospital in the management of anorexia nervosa and to compare it with international recommendation. We propose to illustrate by a case report and review international recommendations on this topic while undertaking a review of the literature based on a Medline search using the following keywords: anorexia, nervosa adolescence, management, guidelines. Case report: AS, 16 years old, addressed to us by the school doctor for management of anorexia nervosa evolving for two years without improvement through outpatient care. His condition was considered precarious requiring urgent care in a medical hospital. She was then hospitalized at the Institute of Nutrition with a weight contract to achieve, She received a gradual refueling strongly denied. We have provided a psychological support by moving on site three times a week to help establish a good therapeutic alliance. After three weeks, the teenager has reached an acceptable weight for its output to the hospital and additional support at the outpatient child psychiatry with supportive psychotherapy. Two months later, she developed depression because of the weight gain. The appointment at the dietician was continued three months after hospitalization. At 10 months of the hospitalization, the girl had good grades and was not amenorrheic. However, on the psychological level she kept the same traits and intrafamilial relationships were marked by the seal of the manipulation. Subsequently, the teenager has spaced the consultations then lost sight. Currently, at 15 months of the hospitalization, parents describe a relapse, with a dietary restriction without amenorrhea ad a refusal to take weight. In management of this patient, we followed the recommendations of the literature namely those of the High Authority of Health and NICE (National Institute

    Native American grape (Vitis) species have many desirable properties for winegrape breeding, but hybrids of these non-vinifera wild grapes with Vitis vinifera often have undesirable aromas. Other than the foxy-smelling compounds in Vitis labrusca and Vitis rotundifolia , the aromas inherent to American Vitis species are not well characterized. In this paper, the key odorants in wine produced from the American grape species Vitis riparia and Vitis cinerea were characterized in comparison to wine produced from European winegrapes (V. vinifera). Volatile compounds were extracted by solid-phase microextraction (SPME) and identified by gas chromatography-olfactometry/mass spectrometry (GC-O/MS). On the basis of flavor dilution values, most grape-derived compounds with fruity and floral aromas were at similar potency, but non-vinifera wines had higher concentrations of odorants with vegetative and earthy aromas: eugenol, cis-3-hexenol, 1,8-cineole, 3-isobutyl-2-methoxypyrazine (IBMP), and 3-isopropyl-2-methoxypyrazine (IPMP). Elevated concentrations of these compounds in non-vinifera wines were confirmed by quantitative GC-MS. Concentrations of IBMP and IPMP were well above sensory threshold in both non-vinifera wines. In a follow-up study, IBMP and IPMP were surveyed in 31 accessions of V. riparia, V. rupestris, and V. cinerea. Some accessions had concentrations of >350 pg/g IBMP or >30 pg/g IPMP, well above concentrations reported in previous studies of harvest-ripe vinifera grapes. Methyl anthranilate and 2-aminoacetophenone, key odorants responsible for the foxiness of V. labrusca grapes, were undetectable in both the V. riparia and V. cinerea wines (<10 μg/L).

    The grape is as old as that of man and is intermingled with it; details of grape growing of figure in mosaics of fourth dynasty of Egypt(2440 B.C) and later the grape as commercial crop is assuming increasing importance. In addition; grapes are the world's biggest most widespread deciduous fruit crop. About one acre in every 125 cultivated acres in the world is in grapes and one person in every 100 works in more phase of the grape and products business. About 55% of the world grape production goes into wine and about 15% into raisins. The balance is grown mainly for the table grapes, juice and other products. The vinfera grape is predominate (Chiders, 1983). According to the statistics of FAO in 1989 the total acreage of grape vine was about 8, 424, 000 hectare which produced 59, 158, 000 metric tones of fruits. Nowadays, in A.R.E, grapes are considered the second fruit in egypt. The total area increased in last few years under the new land reclamation and different soil types, its total area reached about 118826 faddans produced about 786968 metric tons according to the last statistics of the ministry of agriculture in 1994. 25 tabs., 104 refs

    2012-03-01

    Full Text Available The production and commercialization of Brazilian grape juice is increasing annually, mainly due to its typicality, quality, and nutritional value. The present research was carried out in view of the great significance of Brazilian grape juice for the grape and wine industry. The purpose of this study, therefore, was to assess its composition as well as the discrimination between grape juice and other beverages. Twenty four samples of whole, sweetened, and reprocessed grape juices, grape nectar, and grape beverage were evaluated. Classical variables were analyzed by means of physicochemical methods; tartaric and malic acids, by HPLC; methanol, by gas chromatography; minerals, by atomic absorption spectrophotometry. These products were discriminated by the Principal Component Analysis (PCA. Results show that whole and sweetened grape juices were discriminated from other grape products because they featured higher values of total soluble solids, tartaric and malic acids, most minerals, phenolic compounds, and K/Na ratio, whereas grape nectar and grape beverage presented higher values of ºBrix/titratable acidity ratio. Reprocessed juice was discriminated due to its higher concentrations of Li and Na and lower hue.

  11. The fermentation kinetics and physicochemical properties of special beer with addition of Prokupac grape variety

    2015-01-01

    Full Text Available Over the last decade, the market of special beers with improved healthy function and/or with new refreshing taste has significantly increased. One of the possible solutions enables grape and mixing beer with bioactive component responsible for well known health promoting action of red wine. The influence of the addition of Prokupac grape on the physicochemical properties and the fermentation kinetics of the grape beer were studied and results were compared with control lager beer. The effect of grape addition on the activity of yeast was also studied. Original extract, alcohol content, degree of fermentation, fermentation rate and yeast growth were significantly higher in beers with grapes as a consequence of higher concentration of simple sugars in grapes compared with pure wort. Based on the CIELab chromatic parameters the color of grape beer samples was yellow with certain proportion of redness, while the control beer was purely yellow. The increase in the concentration of grape mash affects the reduction of lightness and yellowness of beers, while the redness of samples was directly proportional with grape quantity. The phenolic content and antioxidant capacity of grape beers was remarkably higher compared with control beer, which indicates that the grape beer is a better source of natural antioxidants than regular lager beer.

    Analysis of numerous vineyards has revealed a very high degree of variation exists at the within vineyard scale and may outweigh in some cases broader mesoclimatic and geological factors. For this reason, selective harvest of high quality wine grapes is often conducted and based on subjective field sensory analysis (taste). This is an established practice in many wine growing regions. But the relationships between these subjective judgments to principle soil and grapevine physiological characteristics are not well understood. To move toward greater understanding of the physiological factors related to field sensory evaluation, physiological data was collected over the 2007 and 2008 growing seasons in a selectively harvested premium production Napa Valley estate vineyard, with a history of selective harvesting based on field sensory evaluation. Data vines were established and remained as individual study units throughout the data gathering and analysis phase, and geographic information systems science (GIS) was used to geographically scale physiological and other data at the vineyard level. Areas yielding grapes with perceived higher quality (subjective analysis) were characterized by vines with 1) statistically significantly lower (P grape berry diameter (R2 = 0.616 in 2007 and 0.413 in 2008) and similar strong correlations existed for berry weight (R2 = 0.626 in 2007 and 0.554 in 2008). A trained sensory panel performed a sensory analysis and characterized fruit using and a multivariate, principal components, analysis (PCA). This approach indicated that grapes from vines with lowest midday leaf water potential at veraison (grapes from vines of > -1.5 MPa were characterized by vegetal flavors and astringent and bitter seeds and skins. Data from vines were grouped into vines experiencing MD at veraison of -1.5 MPa and subjected to single factor analysis of variance. This analysis revealed statistically significant differences (P less than 0.05) in many of the above

    Nitrogen is an important element for grapevine and winemaking, which affects plant development, grape juice fermentation and has a potential effect in modulating wine quality. The aim was to study the influence of foliar applications of riboflavin (vitamin B2) to vineyard on grape nitrogen composition. This vitamin has a reported capacity to protect different plant species, but its application to favor grape and grape juice quality had not previously been studied. This work reports the oenological properties and the effect on amino acid concentration of grape juices obtained from grapes treated with riboflavin at two different doses compared to control. Results showed that probable alcohol, malic acid, color intensity and hue had significant differences when the riboflavin treatments were applied. Most of the amino acids presented the highest concentrations when the lowest riboflavin dose was used. These results are promising in terms of fermentation development and grape juice nitrogen composition. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The study investigates the pollution with heavy metals of grapes and soil. The grapes nourish from the respective soil, with all existing substances: either nutrients or toxic materials. This link, between grapes and soil, made mandatory to focus on observing the level of toxic materials in both samples grapes and land. The aim of this research is to analyze the level of Cd and Pb in Vitis vinifera L. grape fruits and soil, by flame atomic absorption spectrometry (FAAS method. The grapes and the soil used in this work were sampled from the Murfatlar City, a nonindustrial area, placed far from the car traffic pollution. Cd and Pb were quantified, after the chemical mineralization of the samples using nitric acid. It can be noticed that the values of cadmium and lead concentrations in grapes were lower than the recommendable maximum limit.

    The anthocyanins of Kyoho grape juice-making pomace, Cabernet Sauvignon grape winemaking pomace and their fresh skin were identified and quantified by high-performance liquid chromatography-tandem mass spectrometry, and the influence of processing on the anthocyanin profiles was investigated. Twenty-three and 16 anthocyanins were found in fresh skin of Kyoho and Cabernet Sauvignon grapes, respectively. Malvidin 3-(trans)-coumaroyl-5-diglucoside and malvidin 3-glucoside were the most abundant anthocyanin in fresh skin of Kyoho and Cabernet Sauvignon grapes, respectively. The cis and trans isomers of malvidin 3-coumaroyl-5-diglucoside are reported in Kyoho grape for the first time. In addition, the anthocyanin content of juice-making pomace of Kyoho grapes and winemaking pomace of Cabernet Sauvignon grapes was significantly lower than the fresh skin samples (p < 0.05). The percentage variation of non-acylated anthocyanins was lower than that of acylated anthocyanins in all pomace samples. Kyoho grape and Cabernet Sauvignon grape showed distinctive anthocyanin profiles. Juice-making pomace is a better source of anthocyanins for use in functional foods than winemaking pomace. © 2012 Society of Chemical Industry.

  16. Bone size and volumetric density in women with anorexia nervosa receiving estrogen replacement therapy and in women recovered from anorexia nervosa.

    2000-09-01

    Anorexia nervosa is associated with bone loss during adulthood, but may also delay skeletal growth and mineral accrual during growth. We asked the following questions. 1) Is anorexia nervosa associated with reduced bone size and reduced volumetric bone mineral density (vBMD)? 2) Is estrogen replacement therapy (ERT) or recovery from anorexia nervosa associated with normal bone size and vBMD? Using dual-energy x-ray absorptiometry, we measured bone size and vBMD of the third lumbar vertebra and femoral neck in a cross-sectional study of 161 female patients: 77 with untreated anorexia nervosa, 58 with anorexia nervosa receiving ERT, 26 recovered from anorexia nervosa, and 205 healthy age-matched controls. Results were expressed as the SD or z-score (mean +/- SEM). Deficits in vertebral body and femoral neck width in untreated women were -1.0 +/- 0.1 and -0.3 +/- 0.1 SD (P anorexia nervosa is due to reduced bone size and reduced vBMD. Although causality cannot be inferred in cross-sectional studies, the data are consistent with the view that malnutrition may contribute to reduced bone size, whereas estrogen deficiency may reduce vBMD. The use of ERT early in disease is a reasonable component of management if the chance of recovery appears remote.

  18. Peculiar enlargement of the nasopharynx in patients with anorexia nervosa

    Okamoto, K.; Ito, J.; Tokiguchi, S.; Kuwabara, G.; Nishihara, M.

    1995-01-01

    We examined the nasopharynx and brain in 17 patients with anorexia nervosa by CT and compared the findings with those of 44 normal subjects and of 5 patients of the same age with marked emaciation caused by various psychiatric disorders. An enlarged nasopharyngeal space with a flattened posterior wall and enlarged lateral pharyngeal recesses were demonstrated in all patients with anorexia nervosa whose weight was lowest at the time of the CT examination, and these CT features regressed or became normal quickly after they had gained some weight. This characteristic enlargement of the nasopharynx and lateral pharyngeal recesses was observed neither in the markedly emaciated patients (2 with schizophrenia, 1 with major depression, 1 with stupor and the other with an extremely unbalanced diet) nor in 44 normal subjects without emaciation. These features were therefore thought to be characteristic and of diagnostic significance. (orig.). With 5 figs., 3 tabs

  19. The Disjointed Historical Trajectory of Anorexia Nervosa Before 1970.

    Court, John P M; Kaplan, Allan S

    2016-01-01

    Responses in pre-modern eras to anorexia nervosa (as now understood) varied widely, from religious piety and sanctity through fear and superstition. While noting briefly the limited conceptualizations from pre-modern history this article is primarily focused from the late 19th century, commencing with helpful but tentative formulations of anorexia nervosa for early-modern medicine that were laid out, consistently between themselves, by Lesègue, Gull and Osler. Yet that promising biomedical advent was superseded for more than a half-century by deep, internal divisions and bitter rifts that festered between three medical disciplines: neurology; Freudian psychotherapy; and Kraepelinian biological psychiatry. Mid-20th century developments preceded the 1960-1980s' improved understanding of suffering and movement toward effective remediation introduced by Dr. Hilde Bruch.

  20. Blood-letting in anorexia nervosa: a case study.

    Morgan, J F; Lacey, J H

    2000-05-01

    Deliberate blood-letting has been characterized as an alternative to purging behavior in bulimia. We describe a female healthcare worker with an 8-year history of restrictive anorexia nervosa, who initially presented with anemia, using blood-letting, cold baths, and starvation to control her mental state. In contrast with the previous cases of bulimia, the aim of blood-letting in this case of anorexia nervosa was to achieve anemia. She compared the psychic correlates of anemia to emaciation, rather than to deliberate self-harm or purging. We note that mainstream 19th century psychiatry prescribed "baths, blood-letting and diet" as a treatment of "madness." Copyright 2000 by John Wiley & Sons, Inc.
