Effect of Germacrene-Rich Essential Oil of Parentucellia latifolia (L.) Caruel Collected in Central Sicily on the Growth of Microorganisms Inhabiting…
2022
In the present study, the chemical composition of the essential oil from aerial parts of Parentucellia latifolia (L.) Caruel collected in Central Sicily was analyzed by gas chromatography and gas chromatography–mass spectrometry. The results showed the presence of sesquiterpene hydrocarbons, with germacrene D and germacrene B accounting, respectively, for 59.2% and 24.3% of the total oil. Different colonies of bacteria and fungi frequently affect cellulosic objects such as books stored in libraries and museums. The antibacterial and antifungal activity against some microorganisms infesting historical-artistic craftsmanship was determined, demonstrating that the essential oil was particular…

Chemical composition and antimicrobial activity of the essential oil from aerial parts of Micromeria fruticulosa (Bertol.) Grande (Lamiaceae) growing…
2007
The essential oil of aerial parts of Micromeria fruticulosa (Lamiaceae) growing wild in Southern Italy was obtained by hydrodistillation and analysed by GC and GC–MS. Sixty-one compounds, representing 91.3% of the oil, were identified. The major components were γ-terpinene (14.5%), β-caryophyllene (12.6%), p-cymene (8.9%), α-pinene (8.2%) and β-bisabolene (7.2%). The essential oil showed action mainly against Gram-positive bacteria. Copyright © 2007 John Wiley & Sons, Ltd.
Identification of Brassicadiene, a Diterpene Hydrocarbon Attractive to the Invasive Stink Bug Bagrada hilaris, from Volatiles of Cauliflower Seedling…
2020
Brassicadiene, a novel tricyclic diterpene hydrocarbon, was identified by a combination of mass spectrometry, microchemical tests, and analysis of NMR spectra. The compound constitutes >90% of the volatile organic compounds produced by cauliflower seedlings, Brassica oleracea var. botrytis. The invasive stink bug Bagrada hilaris is strongly attracted to brassicadiene, providing a mechanism for this herbivore, which specializes on cruciferous plants, to locate its hosts in a nutrient-rich and vulnerable stage.

Lastentarhanopettajaopiskelijoiden kokemuksia erilaisista pedagogisista lähestymistavoista koulutuksen sisällöissä
2014
Varhaiskasvatussuunnitelman perusteissa (2005) erilaiset pedagogiset lähestymistavat on nostettu omaksi luvukseen. Varhaiskasvatuksen ammattilaisilta voidaan siis odottaa aiheen tuntemusta. Tässä tutkimuksessa selvitettiin lastentarhanopettajaopiskelijoiden kokemuksia erilaisten pedagogisten lähestymistapojen käsittelystä koulutuksen sisällöissä. Kyseisistä lähestymistavoista tutkimukseen valittiin Reggiolainen lähestymistapa, Steinerpedagogiikka, Freinet-pedagogiikka sekä Montessoripedagogiikka. Tutkimuksessa haettiin vastauksia seuraaviin tutkimuskysymyksiin; Miten riittävänä opiskelijat kokivat saamansa tiedon määrän koskien erilaisia pedagogisia lähestymistapoja? Missä ja mitä tietoa op…
Peer selection and influence : Students’ interest-driven socio-digital participation and friendship networks
2020
Digital technologies have been increasingly embedded in students’ everyday lives. Interest-driven socio-digital participation (ISDP) involves students’ pursuit of interests mediated by computers, social media, the internet, and mobile devices’ integrated systems.ISDPis likely to intertwine closely with young people’s social networks that has been scarcely studied quantitatively. To close this gap, the present paper investigated students’ peer selection and influence effects of the intensity of their ISDP and friendship networks. We collected two-wave data by administering a peer nomination to trace students’ friendship networks with peers and a self-reported questionnaire to examine student…
Natural Ingredients of Transdermal Drug Delivery Systems as Permeation Enhancers of Active Substances through the Stratum Corneum
2023
In recent years, significant progress has been made in transdermal drug delivery systems, but there is still a search for enhancers that can improve the absorption of active substances through the stratum corneum. Although permeation enhancers have been described in the scientific literature, the use of naturally occurring substances in this role is still of particular interest, because they can offer a high level of safety of use, with a low risk of skin irritation, and high efficiency. In addition, these ingredients are biodegradable, easily available, and widely accepted by consumers due to the growing trust in natural compounds. This article provides information on the role of naturally…
