Composition of the essenthial oil of Petagnaea gussonei (Sprengel) Rauschert, a relict species from Sicily (Southern Italy).
2008
The essential oil from leaves, stems and roots of Petagnaea gussonei (Sprengel) Rauschert ( = Petagnia saniculifolia Guss.), endemic to the Nebrodi Mountains (Sicily, Italy), has been analysed by the gas chromatography–mass spectrometry (GC–MS) system on two fused-silica capillary columns of different polarities. A total of 94 components were identified. Quantitative and qualitative differences were found among the analysed parts. The principal compounds from the leaves oil were found to be (w/w%) germacrene D (19.9%), γ-muurolene (7.96%) and caryophyllene oxide (6.85%), while in the oil from stems hexadecanoic acid (23.40%), germacrene D (18.50%) and (Z,Z)-9,12-octadecadienoic acid (13.20%…
Chemical Composition, Antioxidant Properties and Antimicrobial Activity of the Essential Oil of Murraya Paniculata Leaves from the Mountains of Centr…
2012
The essential oil of Murraya paniculata L leaves from the mountains of the Central Region of Cuba, obtained by hydrodistillation, was analyzed by gas chromatography-mass spectrometry. Eighteen compounds, accounting for 95.1% of the oil were identified. The major component was β-caryophyllene (ca. 30%). The antioxidant activity of essential oil was evaluated against Cucurbita seed oil by peroxide, thiobarbituric acid and p-anisidine methods. The essential oil showed stronger antioxidant activity than that of butylated hydroxyanisole and butylated hydroxytoluene, but lower than that of propyl gallate. Moreover, this antioxidant activity was supported by the complementary antioxidant assay in…

Phytoseiid mites from the Basilicata region (Southern Italy): species diversity and redescription of Typhloseiulus arzakanicus (Arutunjan) with a key…
2017
A survey of phytoseiid mites was carried out in the Basilicata region (Southern Italy) between 1976 and 2014 on wild and cultivated plants. A total of 38 species belonging to eleven genera and two subgenera were found on 59 plant species. The most common species was Euseius finlandicus (Oudemans) (39%) followed by Typhlodromus (Typhlodromus) exhilaratus Ragusa (32.2%), Kampimodromus aberrans (Oudemans) (27.1%), Typhlodromus (Anthoseius) cryptus (Athias-Henriot) (23.7%). Typhloseiulus arzakanicus (Arutunjan), found for first time in Italy, is redescribed here, while the male of this species is described for the first time. A dichotomic key of the species belonging to the genus Typhloseiulus …

Some Previously Relevant Aspects of Academic Life: Venia Legendi and the Status of a Private Docent in the World and in Riga Polytechnicum (1862–1896)
2021
The study examines the status of a private docent, the academic position which was introduced across the world in the 18th century and which also existed in Latvia from the second half of the 19th century until the end of World War II. The status of the private docent as it used to be understood in Latvia is compared with other countries, mainly considering German-type universities. Definition of the terms «venia legendi» and «private docent» providing examples of academic activity of the lecturers of Riga Polytechnicum (RP) allow considering these concepts from various perspectives in order to make their meaning and usage in the previous centuries transparent for the users in the 21st cent…
Chemical Composition, In Vitro Bioaccessibility and Antioxidant Activity of Polyphenolic Compounds from Nutraceutical Fennel Waste Extract
2021
Fennel (Foeniculum vulgare Mill.) waste contains a broad range of bioactive molecules, including polyphenols, which have poor bioaccessibility during gastrointestinal digestion. This work aimed to investigate the bioaccessibility of total phenolic compounds and the antioxidant capacity during simulated gastrointestinal digestion using two nutraceutical formulations based on non-acid-resistant (NAR) and acid-resistant (AR) capsules containing aqueous-based extracts from fennel waste. Moreover, to obtain a comprehensive investigation of the polyphenolic constituents of the fennel waste extract, a high-resolution mass spectrometry (Q-Orbitrap) analysis was performed. Notably, chlorogenic acids…

Population Decline of the Capercaillie Tetrao urogallus aquitanicus in the Central Pyrenees
2020
El seguimiento a largo plazo de las aves amenazadas es esencial para estimar las tendencias poblacionales e identificar las posibles causas de declive, siendo particularmente importante en el caso de las aves alpinas que habitan en areas montanosas en los limites de su area de distribucion. Analizamos la tendencia poblacional del urogallo en los Pirineos centrales espanoles a partir de investigaciones realizadas entre 2000 y 2017. Encontramos un declive significativo de la poblacion (alrededor del 58%) en el numero de aves contadas en las areas de exhibicion (lek). la mayoria de los urogallos habitan bosques de coniferas de pino negro con una cobertura elevada de arandano y rododendro en el…
Digenean parasites of the bivalve mollusc Pisidium amnicum in a small river in eastern Finland
1998
The host-parasite relationship between digeneans and a semelparous population of the mollusc. Pisidium amnicum Müller in a small river in eastern Finland was studied during 1992/1993. The parasite prevalence of the population was high. The total prevalence was 45.6% in 1992 (n = 790) and 47.5% in 1993 (n = 160). The dominant digenean, Bunodera luciopercae (34.2% in 1992, 35.0% in 1993), had highest prevalences in July/August and in winter. Two other species, Palaeorchis crassus (7.8% in 1992, 7.5% in 1993) and Phyllodistomum elongatum (4.7% and 5.0%), were rare during the winter. The prevalence of B. luciopercae increased as clams aged, while the other species were most common in middle-siz…
