Stability of Carotene and Phenols of Sea Buckthorn (Hippophae rhamnoides L.) Juice with Pomace during Storage

Sea Buckthorn (SB) juice is rich in biologically active compounds. It has considerable health benefits; thus, it can serve as functional food ingredient. The aim of this study was to determine and compare the total content of polyphenols, antioxidant capacity (FRAP), soluble solid content, pH value, β-carotene content and colour parameters (L*, a*, b*) in berry juice of cultivar 'Leikora' Sea Buckthorn (SB) (Hippophae rhamnoides L.). The treatment was made as control sample of Sea Buckthorn juice (C), and Sea Buckthorn juice with 0.5 % (P0.5); 1 % (P1); 2 % (P2) dried pomace of Sea Buckthorn. The samples were stored at room temperature for physicochemical analysis at interval of 2 months for a total period of 14 months.According to our results, the β-carotene (C to P2 was 3.71, 4.82, 5.49 and 6.52 mg 100 mL−1) as well as the antioxidant capacity of the samples increased with the growth of the pomace content. During storage, degradation occurred in the polyphenol content and antioxidant capacity, but the β-carotene content increased. The increase of the β-carotene content was 94.6 % (C) and 32.7 % (P0.5). The smaller reduction in antioxidant compounds was the higher the sample of pomace content is. The FRAP and total polyphenol values measured during storage confirm that the pomace has antioxidant effect. There is a close correlation between the two parameters, including a positive correlation (r=0.8614), which indicates that a significant part of the antioxidant capacity of buckthorn is due to the presence of different polyphenols

Miniaturized Protein Microarray with Internal Calibration as Point-of-Care Device for Diagnosis of Neonatal Sepsis

Neonatal sepsis is still a leading cause of death among newborns. Therefore a protein-microarray for point-of-care testing that simultaneously quantifies the sepsis associated serum proteins IL-6, IL-8, IL-10, TNF alpha, S-100, PCT, E-Selectin, CRP and Neopterin has been developed. The chip works with only a 4 μL patient serum sample and hence minimizes excessive blood withdrawal from newborns. The 4 μL patient samples are diluted with 36 μL assay buffer and distributed to four slides for repetitive measurements. Streptavidin coated magnetic particles that act as distinct stirring detection components are added, not only to stir the sample, but also to detect antibody antigen binding events. We demonstrate that the test is complete within 2.5 h using a single step assay. S-100 conjugated to BSA is spotted in increasing concentrations to create an internal calibration. The presented low volume protein-chip fulfills the requirements of point-of-care testing for accurate and repeatable (CV < 14%) quantification of serum proteins for the diagnosis of neonatal sepsis

Quality differences assessment in canned sardine (Sardina pilchardus) by fluorescence detection

5 páginas, 4 figuras, 2 tablas.-- This document is the Accepted Manuscript version of a Published Work that appeared in final form in Journal of Agricultural and Food Chemistry, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://dx.doi.org/10.1021/jf970056lChilled (0, 2, 6, 10, 13, and 15 days) and frozen (0, 0.5, 2, 4, 8, and 12 months) sardines were used to determine the influence of such storage times of fish over the quality of the final canned product. Traditional determinations of lipid quality (free fatty acids content, thiobarbituric acid index, and polyene index) were studied and compared with the formation of fluorescent compounds expressed as the ratio between fluorescence readings taken at two excitation/emission maxima (393/463 and 327/415 nm). No clear correlations were found between the common measurements of lipid deterioration and the time of storage prior to canning. Satisfactory correlations were found between the fluorescence ratio obtained from the filling medium of cans and the time of storage of the starting material (r = 0.90 and 0.91 in brine- and oil-canned samples, respectively). According to the present results, fluorescence detection of interaction compounds can provide a rapid and sensible method to assess quality differences in the final product as it relates to the quality of the raw material usedWe thank the Xunta de Galicia for financial support (Project XUGA 402 01B93).Peer reviewe

Is there a hesitation bias for ambiguous color terms?

Betz S, Davids R, Müller C, et al. Is there a hesitation bias for ambiguous color terms? In: Hoffmann R, ed. Elektronische Sprachsignalverarbeitung 2022: Tagungsband der 33. Konferenz Sonderborg, 2.-4. März 2022 . Studientexte zur Sprachkommunikation. Vol 103. Dresden: TuD; 2022.Recent endeavors have successfully tried to equip dialogue systems withhesitations [1][2]. Hesitations are useful when it comes to buying dialogue time orto support listeners in comprehension [2]. It has been found that hesitations further-more create a bias towards complicated concepts [3]. In addition, one particularhesitation, namely lengthening, has gotten comparably little attention in research,despite its subtlety enables it to buy dialogue time without degrading sound quality[4]. In this paper, we investigate whether the hesitation bias can be replicated inclick tasks with ambiguous and complex color terms as hard-to-describe entities,that have audio instructions with and without hesitations. We hypothesize that,analogous to the studies by Arnold [3], listeners will infer that the target referent isa complicated rather than a simple color term when the instruction contains a hes-itation. While our studies cannot replicate the hesitation bias, we provide valuableinsights into the interaction between hesitations and speech processing as well asmethodological considerations for future research

Early Postoperative Pain Trajectories after Posterolateral and Axillary Approaches to Thoracic Surgery: A Prospective Monocentric Observational Study

Less-invasive thoracotomies may reduce early postoperative pain. The aims of this study were to identify pain trajectories from postoperative days 0&ndash;5 after posterolateral and axillary thoracotomies and to identify potential factors related to the worst trajectory. Patients undergoing a posterolateral (92 patients) or axillary (89 patients) thoracotomy between July 2014 and November 2015 were analyzed in this prospective monocentric cohort study. The best-fitting model resulted in four pain trajectory groups: trajectory 1, the &ldquo;worst&rdquo;, with 29.8% of the patients with permanent significant pain; trajectory 2 with patients with low pain (32.6%); trajectory 3 with patients with a steep decrease in pain (22.7%); and trajectory 4 with patients with a steep increase (14.9%). According to a multinomial logistic model multivariable analysis, some predictive factors allow for differentiation between trajectory groups 1 and 2. Risk factors for permanent pain are the existence of preoperative pain (OR = 6.94, CI 95% (1.54&ndash;31.27)) and scar length (OR = 1.20 (1.05&ndash;1.38)). In contrast, ASA class III is a protective factor in group 1 (OR = 0.02 (0.001&ndash;0.52)). In conclusion, early postoperative pain can be characterized by four trajectories and preoperative pain is a major factor for the worst trajectory of early postoperative pain
