    <p>Abstract</p> <p>Background</p> <p>The characterization of three types of Marche (Italy) honeys (Acacia, Multifloral, Honeydew) was carried out on the basis of the their quality parameters (pH, sugar content, humidity) and mineral content (Na, K, Ca, Mg, Cu, Fe, and Mn). Pattern recognition methods such as principal components analysis (PCA) and linear discriminant analysis (LDA) were performed in order to classify honey samples whose botanical origins were different, and identify the most discriminant parameters. Lastly, using ANOVA and correlations for all parameters, significant differences between diverse types of honey were examined.</p> <p>Results</p> <p>Most of the samples' water content showed good maturity (98%) whilst pH values were in the range 3.50 – 4.21 confirming the good quality of the honeys analysed. Potassium was quantitatively the most relevant mineral (mean = 643 ppm), accounting for 79% of the total mineral content. The Ca, Na and Mg contents account for 14, 3 and 3% of the total mineral content respectively, while other minerals (Cu, Mn, Fe) were present at very low levels. PCA explained 75% or more of the variance with the first two PC variables. The variables with higher discrimination power according to the multivariate statistical procedure were Mg and pH. On the other hand, all samples of acacia and honeydew, and more than 90% of samples of multifloral type have been correctly classified using the LDA. ANOVA shows significant differences between diverse floral origins for all variables except sugar, moisture and Fe.</p> <p>Conclusion</p> <p>In general, the analytical results obtained for the Marche honeys indicate the products' high quality. The determination of physicochemical parameters and mineral content in combination with modern statistical techniques can be a useful tool for honey classification.</p

    BACKGROUND: The ChAdOx1 nCoV-19 (AZD1222) vaccine has been approved for emergency use by the UK regulatory authority, Medicines and Healthcare products Regulatory Agency, with a regimen of two standard doses given with an interval of 4-12 weeks. The planned roll-out in the UK will involve vaccinating people in high-risk categories with their first dose immediately, and delivering the second dose 12 weeks later. Here, we provide both a further prespecified pooled analysis of trials of ChAdOx1 nCoV-19 and exploratory analyses of the impact on immunogenicity and efficacy of extending the interval between priming and booster doses. In addition, we show the immunogenicity and protection afforded by the first dose, before a booster dose has been offered. METHODS: We present data from three single-blind randomised controlled trials-one phase 1/2 study in the UK (COV001), one phase 2/3 study in the UK (COV002), and a phase 3 study in Brazil (COV003)-and one double-blind phase 1/2 study in South Africa (COV005). As previously described, individuals 18 years and older were randomly assigned 1:1 to receive two standard doses of ChAdOx1 nCoV-19 (5 × 1010 viral particles) or a control vaccine or saline placebo. In the UK trial, a subset of participants received a lower dose (2·2 × 1010 viral particles) of the ChAdOx1 nCoV-19 for the first dose. The primary outcome was virologically confirmed symptomatic COVID-19 disease, defined as a nucleic acid amplification test (NAAT)-positive swab combined with at least one qualifying symptom (fever ≥37·8°C, cough, shortness of breath, or anosmia or ageusia) more than 14 days after the second dose. Secondary efficacy analyses included cases occuring at least 22 days after the first dose. Antibody responses measured by immunoassay and by pseudovirus neutralisation were exploratory outcomes. All cases of COVID-19 with a NAAT-positive swab were adjudicated for inclusion in the analysis by a masked independent endpoint review committee. The primary analysis included all participants who were SARS-CoV-2 N protein seronegative at baseline, had had at least 14 days of follow-up after the second dose, and had no evidence of previous SARS-CoV-2 infection from NAAT swabs. Safety was assessed in all participants who received at least one dose. The four trials are registered at ISRCTN89951424 (COV003) and ClinicalTrials.gov, NCT04324606 (COV001), NCT04400838 (COV002), and NCT04444674 (COV005). FINDINGS: Between April 23 and Dec 6, 2020, 24 422 participants were recruited and vaccinated across the four studies, of whom 17 178 were included in the primary analysis (8597 receiving ChAdOx1 nCoV-19 and 8581 receiving control vaccine). The data cutoff for these analyses was Dec 7, 2020. 332 NAAT-positive infections met the primary endpoint of symptomatic infection more than 14 days after the second dose. Overall vaccine efficacy more than 14 days after the second dose was 66·7% (95% CI 57·4-74·0), with 84 (1·0%) cases in the 8597 participants in the ChAdOx1 nCoV-19 group and 248 (2·9%) in the 8581 participants in the control group. There were no hospital admissions for COVID-19 in the ChAdOx1 nCoV-19 group after the initial 21-day exclusion period, and 15 in the control group. 108 (0·9%) of 12 282 participants in the ChAdOx1 nCoV-19 group and 127 (1·1%) of 11 962 participants in the control group had serious adverse events. There were seven deaths considered unrelated to vaccination (two in the ChAdOx1 nCov-19 group and five in the control group), including one COVID-19-related death in one participant in the control group. Exploratory analyses showed that vaccine efficacy after a single standard dose of vaccine from day 22 to day 90 after vaccination was 76·0% (59·3-85·9). Our modelling analysis indicated that protection did not wane during this initial 3-month period. Similarly, antibody levels were maintained during this period with minimal waning by day 90 (geometric mean ratio [GMR] 0·66 [95% CI 0·59-0·74]). In the participants who received two standard doses, after the second dose, efficacy was higher in those with a longer prime-boost interval (vaccine efficacy 81·3% [95% CI 60·3-91·2] at ≥12 weeks) than in those with a short interval (vaccine efficacy 55·1% [33·0-69·9] at <6 weeks). These observations are supported by immunogenicity data that showed binding antibody responses more than two-fold higher after an interval of 12 or more weeks compared with an interval of less than 6 weeks in those who were aged 18-55 years (GMR 2·32 [2·01-2·68]). INTERPRETATION: The results of this primary analysis of two doses of ChAdOx1 nCoV-19 were consistent with those seen in the interim analysis of the trials and confirm that the vaccine is efficacious, with results varying by dose interval in exploratory analyses. A 3-month dose interval might have advantages over a programme with a short dose interval for roll-out of a pandemic vaccine to protect the largest number of individuals in the population as early as possible when supplies are scarce, while also improving protection after receiving a second dose.

    Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)The phenolic composition of grapes and winemaking by-products (skins from grape marc, and lees) from Brazilian hybrid cultivars BRS Violeta (red) and BRS Lorena (white) was studied. Two vintages, five classes of phenolic compounds, and recovery yields using three dehydration techniques were considered: oven-drying at 50 degrees C (D-50); spray-drying (SD); and freeze-drying (FD). Recovery yields were higher using FD, although less expensive SD was a good alternative for Violeta lees. D50 caused great recovery reduction in Violeta but yielded similar results for Lorena. Violeta winemaking by-products were excellent sources of anthocyanins (mainly non-acylated and p-coumaroylated diglucosides), flavonols (mainly myricetin-based) and hydroxycinnamic derivatives (mainly caffeic-based). Lorena winemaking by-products contained lesser amounts of phenolic compounds, around a tenth of the values found in Violeta grapes for flavonols (mainly quercetin-based), hydroxycinnamic derivatives (mainly caffeic-based) and condensed tannins. Lorena cultivar contained small amounts of trans-resveratrol and its 3-glucoside, which were missing in Violeta cultivar. (C) 2014 Elsevier Ltd.

    Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Banana peel is an underused by-product that can be processed to obtain flour that is more easily stored for further uses. The extracts of banana peel flour exhibited a high total phenolic content (around 29 mg/g, as GAE) due to the occurrence of important amounts of flavonoid phenolics: highly polymerized prodelphinidins (around 3952 mg/kg), followed by decreasing lower contents of flavonol glycosides (mainly 3-rutinosides and predominantly quercetin-based structures, accounting for around 129 mg/kg), B-type procyanidin dimers and monomeric flavan-3-ols (jointly around 126 mg/kg). The high total phenolic content of extracts of banana peel flour is likely responsible for the very high antioxidant activity (mu M/g, as Trolox equivalents) measured by three different methods: FRAP, around 14 mu M/g; ABTS, around 242 mu M/g; and ORAC, around 436 mu M/g. All these results suggest the interest in going in depth of the good use of banana peel as a profitable source of bioactive phenolic compounds. (C) 2013 Elsevier Ltd.

    Occurrence Of Low Molecular Weight Phenolics In Vitis Vinifera Red Grape Cultivars And Their Winemaking By-products From São Paulo (brazil)

    The content of low molecular weight phenolic compounds present in winemaking by-products (skins from grape marc and wine lees) of red wine made from the Vitis vinifera grape cultivars Cabernet Sauvignon and Cabernet Franc in the state of São Paulo (Brazil) has been examined. The study was extended to two consecutive years and showed that winemaking by-products still contained high concentrations of interesting functional and bioactive phenolic compounds. In addition to original grape phenolics, the winemaking by-products contained new phenolics originated by the action of enzymatic (yeast mediated) and chemical reactions during winemaking, including formation of anthocyanin-derived pigments and hydrolysis products from flavonol glycosides and tartaric esters of hydroxycinnamic acids. A total of 19 anthocyanins, 9 pyranoanthocyanins, 18 flavonols, 7 hydroxycinnamic acid derivatives, and 3 resveratrol-based stilbenes were identified. Wine lees have been revealed as an interesting source of flavonol aglycones and pyranoanthocyanins. The best sample preparation technique prior to the extraction of phenolic compounds, with regard to the maintenance of phenolic compound profiles and concentrations, was freeze-drying. However, in the case of lees, spray-drying showed to be also effective in the preservation of phenolic compounds and is a less expensive technique. Oven-drying at 50. °C should be avoided if there is interest in using winemaking by-products for further purposes, since phenolic compound concentrations were strongly reduced by thermal degradation. © 2014 Elsevier Ltd.62500513Amico, V., Napoli, E.M., Renda, A., Ruberto, G., Spatafora, C., Tringali, C., Constituents of grape pomace from the Sicilian cultivar 'Nerello Mascalese' (2004) Food Chemistry, 88, pp. 599-607Babbar, N., Oberoi, H.S., Uppal, D.S., Patil, R.T., Total phenolic content and antioxidant capacity of extracts obtained from six important fruit residues (2011) Food Research International, 44, pp. 391-396Blanco-Vega, D., López-Bellido, F.J., Alía-Robledo, J.M., Hermosín-Gutiérrez, I., HPLC-DAD-ESI-MS/MS characterization of pyranoanthocyanins pigments formed in model wine (2011) Journal of Agricultural and Food Chemistry, 59, pp. 9523-9531Boulton, R., The copigmentation of anthocyanins and its role in the color of red wine: A critical review (2001) American Journal of Enology and Viticulture, 52, pp. 67-87Castillo-Muñoz, N., Fernández-Gonzalez, M., Gómez-Alonso, S., García-Romero, E., Hermosín-Gutiérrez, I., Red-color related phenolic composition of Garnacha Tintorera (Vitis vinifera L.) grapes and red wines (2009) Journal of Agricultural and Food Chemistry, 57, pp. 7883-7891Castillo-Muñoz, N., Gómez-Alonso, S., García-Romero, E., Hermosín-Gutiérrez, I., Flavonol profiles of Vitis vinifera red grapes and their single-cultivar wines (2007) Journal of Agricultural and Food Chemistry, 55, pp. 992-1002Cheng, V.J., Bekhit, A.E.A., McConnell, M., Mros, S., Zhao, J., Effect of extraction solvent, waste fraction and grape variety on the antimicrobial and antioxidant activities of extracts from wine residue from cool climate (2012) Food Chemistry, 134, pp. 474-482Cortés, S., Rodríguez, R., Salgado, J.M., Domínguez, J.M., Comparative study between Italian and Spanish grape marc spirits in terms of major volatile compounds (2011) Food Control, 22, pp. 673-680Ferrandino, A., Carra, A., Rolle, L., Schneider, A., Schubert, A., Profiling of hydroxycinnamoyl tartrates and acylated anthocyanins in the skin of 34 Vitis vinifera genotypes (2012) Journal of Agricultural and Food Chemistry, 60, pp. 4931-4945Hermosín-Gutiérrez, I., Castillo-Muñoz, N., Gómez-Alonso, S., García-Romero, E., Flavonol profiles for grape and wine authentication (2011) Progress in authentication of food and wine, pp. 113-129. , American Chemical Society, ACS Symposium Series, Washington, DC, S.E.

    No full text
    Hydrophilic and lipophilic extracts of ten cultivars of Highbush and Rabbiteye Brazilian blueberries (Vaccinium corymbosum L. and Vacciniumashei Reade, respectively) that are used for commercial production were analysed for antioxidant activity by the FRAP, ORAC, ABTS and β-carotene-linoleate methods. Results were correlated to the amounts of carotenoids, total phenolics and anthocyanins. Brazilian blueberries had relatively high concentration of total phenolics (1622-3457 mg gallic acid equivalents per 100 g DW) and total anthocyanins (140-318 mg cyanidin-3-glucoside equivalents per 100 g DW), as well as being a good source of carotenoids. There was a higher positive correlation between the amounts of these compounds and the antioxidant activity of hydrophilic compared to lipophilic extracts. There were also significant differences in the level of bioactive compounds and antioxidant activities between different cultivars, production location and year of cultivation. © 2014 Elsevier Ltd.
