The paper presents un study regarding the comparative total antioxidant capacity of some fluids extracts of the soluble lipid compounds of Cerasus avium (L.) Moench. syn. Prunus avium (L.) var. sylvestris Ser fruits, popular named wild cherry, species undertaken aiming at exploiting the nutrient profiles and promoting the further development of these indigen phytopharmaceutical resources. For analysis, the photo-chemiluminescence method, ACL procedure, Analytik Jena AG, by comparing with the standard Trolox® solution, was used. Wild cherry fruits fluid extracts analyzed emphasize an increased total antioxidative capacity which may be attributed to the high level content of polyphenolic compounds and minerals content which sustains the possibility to use this valuable vegetal product for nutraceutical or comeceutical preparations.

UDK: 634.2:574.4]:502(497.6 “Konjuh“) The area of the protected landscape "Konjuh" is distinguished by quality forest ecosystems, featuring diverse fruit-bearing forest species, which contributes to the conservation of biodiversity of the protected landscape "Konjuh". The aim of the paper is to assess the state of biodiversity of fruit-bearing species in the forest ecosystems of the study area, with the emphasis on determining the genus richness as a basis for conservation (in/ex situ), breeding and economic use. During the vegetation season in 2015 and 2016, several relevés (phytosociological plot) were made in the Protected Landscape "Konjuh". The results of the research indicate the high level of variability for most of the species according to characteristics of biology, pomology, and ecology. The fruit trees, like the noble hardwood, are wild cherry, (Prunus avium L.), wild pear (Pyrus communis L.), wild apples (Malus sylvestris Mill.), Breccia (Torminalis clusii M. Roem.), Sorbus aria L. et all, Wild cherry, Vrapcarka (Prunus avium L.) is the most famous forest fruit grower, occurs as a single tree or in smaller groups (Noćajević, 2009). The benefits of fruit-bearing forest species are emphasized in the bloom and the fruiting time, when "decorated" forest provide a rich bee pasture and feeding nutriment for forest fauna (Orešković et al. 2006). Fruit-bearing Forest species are significant as the genera of the varieties and as a basis for the grafting for high-grade varieties. Also, they are important for humans from the aspect of ecology, nutrition, dietotherapy, pharmacology and bioenergy balance.

AbstractPhysiological balance between pro- and antioxidative processes is crucial for placentation and further development of fetus and placenta. Parameters of pro- and antioxidative profile may serve as markers of proper course of pregnancy. The aim of study was to assess whether the balance between pro- and antioxidative parameters during placentation phase in bovine placenta is maintained. Placental and blood samples were collected from healthy, HF, pregnant (2nd-3rd month) cows (n = 8) in slaughterhouse and in farm, respectively. Formylokinurenine and bityrosine content were measured spectrofluorimetrically in blood plasma and tissue homogenates while metabolites of lipid peroxidation, total antioxidant capacity, SH groups and activity of antioxidative enzymes (glutathione peroxidase and superoxide dismutase) were determined in examined tissues by spectrophotometry. Western blotting was used to confirm the presence of enzymatic proteins in placenta. Results: Local profile in tissues was more pronounced than general profile in blood plasma. Activities of antioxidative enzymes were significantly (p < 0.05) higher in 2nd compared to 3rd month of pregnancy in maternal part of placenta while prooxidant parameters showed opposite relationship. Obtained results showed significant differences when compared to data from non-pregnant animals or time of parturition. Further studies are necessary for elucidation of placentation phase in cows.

Abstract During a regular survey of declining forests in 2011, sudden dieback symptoms were observed on scattered wild cherry trees (Prunus avium) in a mixed deciduous forest stand, located in the flood plain area of the Rába River, in northwest Hungary. In this study, we correlated both soil conditions and presence of Phytophthora spp. to dieback of cherry trees. Two Phytophthora species, P. polonica and P. plurivora, were isolated from the rhizosphere soil of the dying trees. By contrast, only P. polonica was recovered from the necrotic tissues of symptomatic roots. Stem and root inoculation tests on cherry seedlings showed pathogenicity of both species, although P. polonica proved to be more virulent. This is the first report of natural infections of P. polonica.

Potential Use

To avoid use errors when handling medical equipment, it is important to develop products with a high degree of usability. This can be achieved by performing usability evaluations in the product development process to detect and mitigate potential usability problems. A commonly used method is cognitive walkthrough (CW), but this method shows three weaknesses: poor high-level perspective, insufficient categorisation of detected usability problems, and difficulties in overviewing the analytical results. This paper presents a further development of CW with the aim of overcoming its weaknesses. The new method is called enhanced cognitive walkthrough (ECW). ECW is a proactive analytical method for analysis of potential usability problems. The ECW method has been employed to evaluate user interface designs of medical equipment such as home-care ventilators, infusion pumps, dialysis machines, and insulin pumps. The method has proved capable of identifying several potential use problems in designs.
