Effects of heating process of soybeans on ruminal production of conjugated linoleic acids and trans-octadecenoic acids in situ
No full textThe effects of two thermal treatments of soybeans, i.e. roasting (150˚C dry heat) and extrusion (140-150˚C), on conjugated linoleic acids (CLA) and trans-octadecenoic acids (trans-C18:1) productions obtained throughout ruminal C18:2 biohydrogenation in cows were examined. Nylon bags containing raw, roasted or extruded soybeans were incubated in the rumen of dry fistulated cows, during 2, 4, 8, 16 or 24 hours. After incubation of 2-4 h, significantly greater amounts of linoleic acid (C18:2) remained in bags containing extruded and roasted soybeans than in those with raw soybeans, reflecting a lower biohydrogenation of C18:2 in both case. Furthermore, significant and marked accumulations of CLA and trans-C18:1 at a lesser extend were noticed in bags containing extruded soybeans compared to those with raw or roasted soybeans. By calculations of the efficiencies of the three reactions, an inhibition of the C18:2 isomerisation was evidenced with extruded and roasted soybeans, as well as an inhibition of the two reduction steps in presence of extruded soybeans. Consequently, the thermal treatment and the nature of heating process of fat are efficient ways to modulate the CLA and trans-C18:1 ruminal productions
Un enfoque diferente para las políticas europeas de inmigración
No full textThe author¿s starting point is that the European Union lacks a common policy on immigration and political asylum, in spite of such a policy first having been proposed five years ago. The author argues that migrations should be viewed as something that have always existed during humankind¿s history and should be seen as a means to avoid the dangers of an increasingly aged Europe, namely, a serious threat to its system of pensions and a clear comparative disadvantage with respect to the Unites States. Until now country-by-country regulation and overwrought and ungenerous immigration procedures have translated into a failure that has produced an... (Ver más) underground economy, social and labour dumping. This is evident with each successive amnesty granted. There is no indication the flow of irregular immigrants is going to decrease. This state of affairs will only change when the European Union possesses a ¿global and horizontal¿ legal framework that marks a pattern for European governments to follow and when the Council of Europe abandons the rule of unanimity and begins to adopt co-decision procedures with the Parliament.Parte el autor de que la Unión Europea carece de una política común de inmigración y asilo, a pesar de habérselo propuesto desde hace cinco años. El autor aboga por convertir las migraciones, algo consustancial a la historia de la humanidad, en factor para evitar los peligros que se ciernen sobre una Europa envejecida y en serio peligro de continuidad de sus programas de pensiones y en clara desventaja comparativa respecto de Estados Unidos. Hasta ahora la regulación país a país, los procedimientos alambicados de admisión han supuesto un fracaso que ha favorecido la economía sumergida, el dumping social y laboral, patente en las sucesivas amnistías.... (Ver más) No hay perspectivas de que los flujos irregulares vayan a menguar. Las cosas cambiarán solo cuando la UE disponga de un marco legislativo ¿global y horizontal¿ que marque un patrón a los gobiernos europeos, cuando el Consejo Europeo abandone la regla de la unanimidad y empiece a adoptar medidas en codecisión con el Parlamento
Effects of extruded soybeans on CLA concentration in milk
No full textConjugated linoleic acids are geometric and positional isomers of the linoleic acid (Bessa et al., 2000). Recent studies on animal models demonstrated that these intermediates of rumen biohydrogenation may improve health by anticarcinogenic, antiatherogenic, antiobesity and antidiabetic effects and immune system enhancement (Bauman et al., 2001; Pariza et al., 2000; Belury 2002; Peterson et al., 2002). So aim of this work was to study the possibility to increase CLA milk content by the use of a natural source of polyunsaturated fatty acids as extruded soybeans.......
Walter Benjamin in urbani labirint
No full textThe author proposes a new reading of Walter Benjamin's city centred cultural theorizings laid down especially in his seminal »Arcades Project«. Two basic concepts of Benjamin's are singled out: Flanerie and labyrinth. Although Benjamin derived his theory of urban culture form 19th century Paris both the concepts are not enshrined in this realm, but have a relevance for our time as well.Avtor predlaga novo branje na mesto osrediščenih kulturnih teoretizacij, ki jih je Walter Benjamin prikazal predvsem v svojem pomembnem projektu »arkade«. Izpostavljena sta dva osnovna Benjaminova pojma: flanerie in labirint. Čeprav je Benjamin svojo teorijo urbane kulture izpeljal iz Pariza devetnajstega stoletja, njegova pojma nista omejena na to področje, temveč sta pomembna tudi za naš čas
World Resurrection as an Utopian Idea in the Travelogue »Symphonies of the Adriatic, Italy, Paris and London« by Josip Kosor
No full textU radu se interpretira putopis »Simfonije Jadrana, Italije, Pariza i Londona« Josipa Kosora u ključu avangardne utopijske ideje obnove svijeta. Kosorov »transcendentni utopizam« (Oraić Tolić) interpretirat će se na primjeru specifičnoga, hibridnog putopisnog žanra i to interpretacijskim čitanjem dominanti koje uvjetuju njegovu utopijsku misao – estetika (pejzaž), duhovnost (umjetnost), moral (sloboda). Interpretacijom se u tom smislu želi dokazati da je Josip Kosor već na izmaku avangardno-ekspresionističkih strujanja u hrvatskoj književnosti ostao vjeran utopijskoj ideji o obnovi svijeta.In the paper is interpreted the travelogue »Symphonies of the Adriatic, Italy, Paris and London« by Josip Kosor in the key of the expressionist and utopian idea of the world. The beauty of the landscape, art, vision of messianic personalities, and finally the reflection of ethics as inseparable categories of beauty, encourage the author to reflect on the aesthetics and mysticism
Effects of pH and Concentrations of Linoleic and Linolenic Acids on Extent and Intermediates of Ruminal Biohydrogenation in Vitro
No full textThree experiments were conducted by in vitro incubations in ruminal fluid to investigate the effects of pH and amounts of linoleic and linolenic acids on the extent of their biohydrogenation, the proportions of conjugated linoleic acid (CLA) and trans-C18:1 as intermediates, and the ratio trans-10:trans-11 intermediates. The effects of pH and amount of linoleic acid were investigated in kinetic studies, and effects of the amount of linolenic acid were studied with 6-h incubations. With identical initial amounts of linoleic acid, its disappearance declined when the mean pH during incubation was under 6.0 compared with a mean pH over 6.5, and when the amount of linolenic acid increased from 10 to 180 mg/160-ml flask, suggesting an inhibition of the isomerization step of the biohydrogenation. Low pH decreased the ratio of trans-10:trans-11 intermediates. With initial amounts of linoleic acid increasing from 100 to 300 mg, the percentage of linoleic acid disappearance declined, but the amount that disappeared increased, without modification of the trans-10:trans-11 ratio, suggesting a maximal capacity of isomerization rather than an inhibition. Moreover, increasing initial linoleic acid resulted in high amounts of trans-C18:1 and an increase of C18:0 that was a linear function of time, suggesting a maximal capacity for the second reduction step of biohydrogenation. High amounts of initial linolenic acid did not affect the amounts of CLA, trans-C18:1, or the ratio trans-10:trans-11. Based on these experiments, a ruminal pH near neutrality with high amount of dietary linoleic acid should modulate the reactions of biohydrogenation in a way that supports CLA and trans-11C18:1 in the rumen
