Thermally Induced Isomerization of Trilinolein and Trilinoelaidin at 250 A degrees C: Analysis of Products by Gas Chromatography and Infrared Spectro…
2009
Accepted version of an article published in the journal: Lipids The original publication is available at www.springerlink.com, http://dx.doi.org/10.1007/s11745-009-3363-x The products formed by thermally induced isomerization of trilinolein and trilinoelaidin at 250 A degrees C were studied by infrared spectroscopy and gas chromatography. The triglycerides of the 9c12c and 9t12t fatty acids, linoleic and linoelaidic acid respectively, were subjected to thermal treatment under nitrogen in glass. The products were removed at regular intervals and analysed by infrared spectroscopy using a single reflectance attenuated total internal reflectance crystal accessory. Trans-esterification of the pr…
Thermal Induction of 9t12t Linoleic Acid: a New Pathway for the Formation of Conjugated Linoleic Acids
2009
Accepted version of an article published in the journal: International Journal of Engineering and Technology Published version available at: http://www.ijetch.org/papers/066.pdf Thermal induction of 9t12t fatty acid leading to the formation of Conjugated Linoleic Acids (CLA) has been demonstrated by subjecting glyceride, and methyl ester of the acid to heat treatment. Fifteen micro liter portions of the glyceride sample containing 9t12t fatty acid (trilinoelaidin) were placed in micro glass ampoules and sealed under nitrogen and then subjected to thermal treatment at 250oC. The glass ampoules were taken out at regular time intervals, and the contents were subjected to composition analysis b…
Characterization of field isolates of Trichoderma antagonistic against Rhizoctonia solani.
2010
The aim of the present study was to characterize sixteen isolates of Trichoderma originating from a field of sugar beet where disease patches caused by Rhizoctonia solani were observed. Use of both molecular and morphological characteristics gave consistent identification of the isolates. Production of water-soluble and volatile inhibitors, mycoparasitism and induced systemic resistance in plant host were investigated using in vitro and in vivo tests in both sterilized and natural soils. This functional approach revealed the intra-specific diversity as well as biocontrol potential of the different isolates. Different antagonistic mechanisms were evident for different strains. The most antag…
Anthosart Green Tool: Selecting Species for Green Infrastructure Design
2021
The environmental and economic costs of greenery depend on the planning criteria adopted and on the plants used. These costs can become more sustainable and can also be significantly lowered by using native flora and getting inspired by local plant communities. Nature-based solutions entail the use of species that co-occur naturally, thus replicating a model of coexistence consolidated by the evolutionary coherence of the biosphere. Planning, using and (re-)producing – getting inspired by natural ecosystems – may foster the dissemination of ecological awareness, with gardens, avenues, rooftops, walls and balconies seen as spaces available for the urban reconciliation with nature. The Anthos…
A Personalist Ontological Approach to Synthetic Biology
2015
Although synthetic biology is a promising discipline, it also raises serious ethical questions that must be addressed in order to prevent unwanted consequences and to ensure that its progress leads toward the good of all. Questions arise about the role of this discipline in a possible redefinition of the concept of life and its creation. With regard to the products of synthetic biology, the moral status that they should be given as well as the ethically correct way to behave towards them are not clear. Moreover, risks that could result from a misuse of this technology or from an accidental release of synthetic organisms into the environment cannot be ignored; concerns about biosecurity and …
Sabiedrības dihotomija varas attiecību ietvaros
2016
Maģistra darbs tiek veikts sociālās filozofijas jomā, tajā tiek apskatīti tēmas virsrakstā pieteiktie jautājumi, proti, sabiedrības dihotomija un varas attiecības. Kontekstā ar varas attiecībām pētījumā tiek apskatīta vara pēc būtības, tiek definēts varas jēdziens un tā interpretācija šajā pētījumā, kā arī tiek analizēta varas izcelsme indivīda veidošanās procesā. Papildus darbā tiek analizēta masu sabiedrība un pieminētā fenomena pētīšanas tradīcijas. Tiek pamatots masu sabiedrības jēdziens, definēta šā sabiedrības uzbūves modeļa vēsturiskā izcelsme un masu sabiedrības rīcības sekas kādas tā atstāj uz sevi un apkārtējo pasauli…
Lead concentrations in feathers and blood of common blackbirds (Turdus merula) and in earthworms inhabiting unpolluted and moderately polluted urban …
2006
9 pages; International audience; Despite the dramatic decrease of atmospheric lead (Pb) concentrations in urban areas of most industrialised countries, we hypothesised that urban common blackbirds (Turdus merula) may still be contaminated by Pb concentrations of toxicological concern due to transfer from soil through the food chain. We sampled blackbirds and earthworms, one of their main preys, in Besan?, a middle-size city of Eastern France (where atmospheric Pb concentrations decreased from 0.5 microg/m(3) in 1987 to nearly 0 in 2002) and in a rural reference site. Lead concentrations were determined in the tissues of the different functional groups of earthworms (anecic, epigeous and end…
Membrane Insertion and Biogenesis of the Turnip Crinkle Virus p9 Movement Protein
2010
ABSTRACT Plant viral infection and spread depends on the successful introduction of a virus into a cell of a compatible host, followed by replication and cell-to-cell transport. The movement proteins (MPs) p8 and p9 of Turnip crinkle virus are required for cell-to-cell movement of the virus. We have examined the membrane association of p9 and found that it is an integral membrane protein with a defined topology in the endoplasmic reticulum (ER) membrane. Furthermore, we have used a site-specific photo-cross-linking strategy to study the membrane integration of the protein at the initial stages of its biosynthetic process. This process is cotranslational and proceeds through the signal recog…
Biosynthesis of fungal melanins and their importance for human pathogenic fungi
2003
For more than 40 years fungi have been known to produce pigments known as melanins. Predominantly these have been dihydroxyphenylalanine (DOPA)-melanin and dihydroxynaphthalene (DHN)-melanin. The biochemical and genetical analysis of the biosynthesis pathways have led to the identification of the genes and corresponding enzymes of the pathways. Only recently have both these types of melanin been linked to virulence in some human pathogenic and phytopathogenic fungi. The absence of melanin in human pathogenic and phytopathogenic fungi often leads to a decrease in virulence. In phytopathogenic fungi such as Magnaporthe grisea and Colletotrichum lagenarium, besides other possible functions in …
Birth weight, cardiometabolic risk factors and effect modification of physical activity in children and adolescents: pooled data from 12 internationa…
2020
Abstract Objectives Low and high birth weight is associated with higher levels of cardiometabolic risk factors and adiposity in children and adolescents, and increases the risk of cardiovascular diseases, obesity, and early mortality later in life. Moderate-to-vigorous physical activity (MVPA) is associated with lower cardiometabolic risk factors and may mitigate the detrimental consequences of high or low birth weight. Thus, we examined whether MVPA modified the associations between birth weight and cardiometabolic risk factors in children and adolescents. Methods We used pooled individual data from 12 cohort- or cross-sectional studies including 9,100 children and adolescents. Birth weigh…
