    The effects of apple and lemon fiber addition on some properties of kefir were investigated. Five different kefirs were produced (A is control, B, C, D, E, F and G: contain 0.25 % apple fiber, 0.5 % apple fiber, 1 % apple fiber, 0.25 % lemon fiber, 0.5 % lemon fiber and 1 % lemon fiber, respectively) and stored for 20 days at 4±1 °C. pH, titratable acidity, dry matter, water activity, water holding capacity, viscosity, L, a and b values, sensorial analysis, total lactic bacteria, Lactococcus spp., Leuconostoc spp. and yeast counts of kefirs were determined at 1st, 10th and 20th days of storage. The addition of apple and lemon fiber enhanced rheological, microbiological and sensorial properties of kefirs (p<0.01). Apple and lemon fiber could be used for kefir production at a rate of 0.25 or 0.5 %.Istražen je utjecaj dodatka vlakana jabuke i limuna na neka svojstva kefira. U tu svrhu proizvedeno je pet različitih kefira (A je kontrolni, B, C, D, E, F i G: sadrže 0,25 % jabučnih vlakana, 0,5 % jabučnih vlakana, 1 % jabučnih vlakana, 0,25 % limunskih vlakana, 0,5% limunskih vlakana i 1 % limunskih vlakana), koji su bili pohranjeni 20 dana na 4±1 °C. pH, titriracijska kiselost, suha tvar, aktivnost vode, kapacitet zadržavanja vode, viskoznost, L, a i b vrijednosti, senzorska analiza, ukupni broj bakterija mliječne kiseline, Lactococcus spp., Leuconostoc spp. i broj kvasaca u kefiru određeni su 1., 10. i 20. dana skladištenja. Dobiveni rezultati upućuju na to da dodatak vlakana jabuke i limuna poboljšava reološka, mikrobiološka i senzorska svojstva kefira (p<0,01), te da se vlakna jabuke i limuna mogu koristiti za proizvodnju kefira do udjela od 0,25 % ili 0,5 %

    U ovoj studiji je istražena mogućnost zamjene stabilizatora mikrobnom transglutaminazom (MTG) u proizvodnji sladoleda sa smanjenim udjelom masti. Pri tom je također ispitivan utjecaj vremena dodavanja MTG (prije ili nakon toplinske obrade) na svojstva sladoleda. Proizvedeno je 5 različitih uzoraka sladoleda: A i C s 1 jedinicom MTG/g proteina, bez stabilizatora; B i D s 0,5 jedinica MTG/g proteina i 0,35 % stabilizatora, (smjesa karagenana (E 407), guar gume (E 412), ksantan gume (E 415) i natrijevog alginata (E 401)) i E (kontrola) s 0,7 % stabilizatora. MTG je dodavan uzorcima A i B nakon, a uzrocima C i D prije toplinske obrade. Svim uzorcima su određivani porast volumena, viskoznost, svojstva topljenja, pH, titracijska kiselost, suha tvar, udio masti i proteina, senzorska svojstva i mikrostruktura. Sukladno dobivenim rezultatima količina i vrijeme dodatka MTG značajno su utjecali na porast volumena, topljenje, viskoznost, osjet hladnoće, čvrstoću, glatkoću, punoću okusa u ustima, boju, izgled, okus, miris te na mikrostrukturu sladoleda (p<0,01). Također se pokazalo da se MTG može koristiti skupa sa stabilizatorima, no u tom slučaju se treba dodavati nakon toplinske obrade sladoledne smjese. Zaključno, uzorak B se prema rezultatima senzorske analize pokazao najsličnijim kontrolnom uzorku.In this study, the possibility of replacing stabilizers with microbial transglutaminase (MTG) enzyme in fat-reduced ice cream production was studied. In addition, the stage of adding (before or after the heat treatment) the MTG enzyme to ice cream was also investigated. Five different ice creams (A and C containing 1 unit MTG/g protein without stabilizer, B and D containing 0.5 unit MTG/g protein and 0.35 % stabilizer, which also consist of the mixture of Carrageenan (E 407), Guar gum (E 412), Xanthan gum (E 415) and Sodium alginate (E 401), and E (control) containing 0.7 % stabilizer) were manufactured. MTG has been added to samples A and B after heat treatment while it was added to C and D samples before the heat treatment. An experimental analysis related to the overrun, viscosity melting properties, pH, titratable acidity, dry matter, fat, protein, sensorial and microstructural properties of ice creams was carried out. According to the results, the amount and the adding stage of MTG significantly affected overrun, melting, viscosity, coldness, firmness, smoothness, mouth coating, color, appearance, taste, smell scores, and also microstructure of ice creams (p<0.01). Results also showed that MTG could be used together with other stabilizers after heat treatment in the production of ice cream. Moreover, our findings demonstrated that sample B was the closest to control in terms of sensorial properties

    Background: Atrial fibrillation (AF) and renal impairment share a bidirectional relationship with important pathophysiological interactions. We evaluated the impact of renal impairment in a contemporary cohort of patients with AF. Methods: We utilised the ESC-EHRA EORP-AF Long-Term General Registry. Outcomes were analysed according to renal function by CKD-EPI equation. The primary endpoint was a composite of thromboembolism, major bleeding, acute coronary syndrome and all-cause death. Secondary endpoints were each of these separately including ischaemic stroke, haemorrhagic event, intracranial haemorrhage, cardiovascular death and hospital admission. Results: A total of 9306 patients were included. The distribution of patients with no, mild, moderate and severe renal impairment at baseline were 16.9%, 49.3%, 30% and 3.8%, respectively. AF patients with impaired renal function were older, more likely to be females, had worse cardiac imaging parameters and multiple comorbidities. Among patients with an indication for anticoagulation, prescription of these agents was reduced in those with severe renal impairment, p&nbsp;&lt;.001. Over 24&nbsp;months, impaired renal function was associated with significantly greater incidence of the primary composite outcome and all secondary outcomes. Multivariable Cox regression analysis demonstrated an inverse relationship between eGFR and the primary outcome (HR 1.07 [95% CI, 1.01–1.14] per 10&nbsp;ml/min/1.73&nbsp;m2 decrease), that was most notable in patients with eGFR &lt;30&nbsp;ml/min/1.73&nbsp;m2 (HR 2.21 [95% CI, 1.23–3.99] compared to eGFR ≥90&nbsp;ml/min/1.73&nbsp;m2). Conclusion: A significant proportion of patients with AF suffer from concomitant renal impairment which impacts their overall management. Furthermore, renal impairment is an independent predictor of major adverse events including thromboembolism, major bleeding, acute coronary syndrome and all-cause death in patients with AF

    Clinical complexity and impact of the ABC (Atrial fibrillation Better Care) pathway in patients with atrial fibrillation: a report from the ESC-EHRA EURObservational Research Programme in AF General Long-Term Registry

    Background: Clinical complexity is increasingly prevalent among patients with atrial fibrillation (AF). The ‘Atrial fibrillation Better Care’ (ABC) pathway approach has been proposed to streamline a more holistic and integrated approach to AF care; however, there are limited data on its usefulness among clinically complex patients. We aim to determine the impact of ABC pathway in a contemporary cohort of clinically complex AF patients. Methods: From the ESC-EHRA EORP-AF General Long-Term Registry, we analysed clinically complex AF patients, defined as the presence of frailty, multimorbidity and/or polypharmacy. A K-medoids cluster analysis was performed to identify different groups of clinical complexity. The impact of an ABC-adherent approach on major outcomes was analysed through Cox-regression analyses and delay of event (DoE) analyses. Results: Among 9966 AF patients included, 8289 (83.1%) were clinically complex. Adherence to the ABC pathway in the clinically complex group reduced the risk of all-cause death (adjusted HR [aHR]: 0.72, 95%CI 0.58–0.91), major adverse cardiovascular events (MACEs; aHR: 0.68, 95%CI 0.52–0.87) and composite outcome (aHR: 0.70, 95%CI: 0.58–0.85). Adherence to the ABC pathway was associated with a significant reduction in the risk of death (aHR: 0.74, 95%CI 0.56–0.98) and composite outcome (aHR: 0.76, 95%CI 0.60–0.96) also in the high-complexity cluster; similar trends were observed for MACEs. In DoE analyses, an ABC-adherent approach resulted in significant gains in event-free survival for all the outcomes investigated in clinically complex patients. Based on absolute risk reduction at 1 year of follow-up, the number needed to treat for ABC pathway adherence was 24 for all-cause death, 31 for MACEs and 20 for the composite outcome. Conclusions: An ABC-adherent approach reduces the risk of major outcomes in clinically complex AF patients. Ensuring adherence to the ABC pathway is essential to improve clinical outcomes among clinically complex AF patients

    Impact of clinical phenotypes on management and outcomes in European atrial fibrillation patients: a report from the ESC-EHRA EURObservational Research Programme in AF (EORP-AF) General Long-Term Registry

    Background: Epidemiological studies in atrial fibrillation (AF) illustrate that clinical complexity increase the risk of major adverse outcomes. We aimed to describe European AF patients\u2019 clinical phenotypes and analyse the differential clinical course. Methods: We performed a hierarchical cluster analysis based on Ward\u2019s Method and Squared Euclidean Distance using 22 clinical binary variables, identifying the optimal number of clusters. We investigated differences in clinical management, use of healthcare resources and outcomes in a cohort of European AF patients from a Europe-wide observational registry. Results: A total of 9363 were available for this analysis. We identified three clusters: Cluster 1 (n = 3634; 38.8%) characterized by older patients and prevalent non-cardiac comorbidities; Cluster 2 (n = 2774; 29.6%) characterized by younger patients with low prevalence of comorbidities; Cluster 3 (n = 2955;31.6%) characterized by patients\u2019 prevalent cardiovascular risk factors/comorbidities. Over a mean follow-up of 22.5 months, Cluster 3 had the highest rate of cardiovascular events, all-cause death, and the composite outcome (combining the previous two) compared to Cluster 1 and Cluster 2 (all P &lt;.001). An adjusted Cox regression showed that compared to Cluster 2, Cluster 3 (hazard ratio (HR) 2.87, 95% confidence interval (CI) 2.27\u20133.62; HR 3.42, 95%CI 2.72\u20134.31; HR 2.79, 95%CI 2.32\u20133.35), and Cluster 1 (HR 1.88, 95%CI 1.48\u20132.38; HR 2.50, 95%CI 1.98\u20133.15; HR 2.09, 95%CI 1.74\u20132.51) reported a higher risk for the three outcomes respectively. Conclusions: In European AF patients, three main clusters were identified, differentiated by differential presence of comorbidities. Both non-cardiac and cardiac comorbidities clusters were found to be associated with an increased risk of major adverse outcomes

    A comparative study of physicochemical and organoleptic qualities of flavoured yogurts made from cow's and goat's milk and stored for 15 days [İnek ve keçi sütlerinden üretilen ve 15 gün süre ile depolanan meyveli / aromali yogurtlarin fizikokimyasal ve duyusal özelliklerinin belirlenmesi üzerine karşilaştirmali bir araştirma]

    The effects of 2 different types of milk (cow's and goat's milk). 4 types of flavouring (coffee, strawberry, cherry and peach) and 15 days of storage on the physical, chemical and organoleptic qualities of flavoured yogurts were investigated and the results summarised below. The results of the analysis indicate that different types of milk and flavouring had statistically significant effects (p0.05). The organoleptic evaluations, namely colour and appearance, texture and aroma (taste and smell), were affected significantly (p0.05). In an expert panel evaluation of all the samples, the cow's milk yogurts received higher ratings than the goat's milk yogurts. The strawberry yogurts were rated the best, followed by the peach, cherry and coffee varieties. This order of preference did not change according to the storage time

    Ischemia/reperfusion (I/R) causes formation of Reactive Oxygen Species (ROS) in tissues, in response to which injured cells improve a number of defense mechanisms including Glutathione S-Transferases (GSTs). The aim of this study was to investigate the expressions of GSTA1 and GSTP1 following Thioredoxin (Trx) and N-nitro-L-arginine methyl ester (L-NAME) treatment in a rat model of hepatic I/R model. A total of 50 Wistar rats were randomly allocated into 5 groups: sham (n = 10), control (I/R) (n = 10), Trx (n = 10), L-NAME (n = 10), and Trx+L-NAME (n = 10). With an exception to those in sham group, all rats were subjected to a hepatic ischemia process for an hour and then subsequent reperfusion. GSTA1 and GSTP1 expressions in the liver tissues were determined by immunohistochemical method. The GSTA1 expression was absent in sham group while varying degrees of expression occurred in other groups. The GSTA1 expression was significantly higher in Trx/L-NAME group compared to other groups (p 0.05). As a result, we think that GSTA1 expression may have increased in response to I/R as a part of the liver oxygen radical scavenging process
