The Sicilian taxa of Genista sect. Voglera and their phytosociological framework

2012

The phytosociological role of taxa of Genista sect. Voglera in the vegetation context of Sicily is here examined. It was carried out on plant communities characterised by the Sicilian endemics G. aristata, G. madoniensis and G. cupanii. These taxa and their floristic settlement have been examined from the biogeographical point of view. Basing on our results, the popu- lations of G. madoniensis are to be referred to a new association named Cisto salvifolii- Genistetum madoniensis, ascribed to the class Cisto-Lavanduletea. Multivariate analysis shows a clear ecological differentiation of G. madoniensis with respect to the other Sicilian species. Instead, its habitus and ecology are closer to …

Lavandula spp. (Lavender): In Vitro Culture, Regeneration of Plants, and the Formation of Essential Oils and Pigments

1991

Lavandula species are of great interest due to their content of essential oils, which are important to the perfume, cosmetic, flavoring and pharmaceutical industries. They also have numerous other applications, including their uses as ornamental and melliferous plants.

Screening of microalgae and LED grow light spectra for effective removal of dissolved nutrients from cold-water recirculating aquaculture system (RAS…

2019

Popularity of recirculating aquaculture systems (RAS) is increasing. Because of the high water recirculation rate, dissolved nutrients originating from fish feed are concentrated enough in RAS wastewater (WW) to enable growth of primary producers, e.g. microalgae. This study evaluated nitrate-nitrogen (NO3-N) and phosphate-phosphorus (PO4-P) removal efficiency of ten temperate zone freshwater microalgae species during their exponential growth phase in unfiltered RAS WW at 17 ± 0.5 °C. Growth and nutrient uptake efficiency of six green and four non-green microalgae strains were compared between WW and reference growth medium in batch monocultures. The effect of three different LED grow light…

Kotimaisen 2010-luvun lavarunouden kentillä ja laidoilla : havainnointeja lavarunouden teoriasta, arvoista ja keinoista

2014

Kotimainen lavarunous elää 2010-luvulla vahvimmin Poetry slam -kilpailuissa, Helsinki Poetry Connection -runoryhmittymän toiminnassa ja tapahtumissa sekä runoiltojen open mic -osuuksissa. Lavarunous on omien runojen esittämistä esiintymiskonteksti huomioon ottaen ja siihen panostaen, mikä erottaa lavarunouden oleellisesti runonlausunnasta ja -luennasta. Lavarunoudella on erittäin vahvat yhteydet musiikkiin, stand-up–komiikkaan ja rap-lyriikkaan. Tässä kirjallisuuden pro gradu -työssä tarkastelen suomalaisen tämänhetkisen lavarunouden historiaa, estetiikkaa ja poetiikkaa. Pyrin määrittelemään lavarunouden käsitettä Julia Novakin ja Susan B. A. Somers-Willettin teorioihin ja määritelmiin peil…

Biomolecular characterization of wild sicilian oregano: phytochemical screening of essential oils and extracts, and evaluation of their antioxidant a…

2013

An extensive survey of wild Sicilian oregano was made. A total of 57 samples were collected from various sites, followed by taxonomic characterization from an agronomic perspective. Based on morphological and production characteristics obtained from the 57 samples, cluster analysis was used to divide the samples into homogeneous groups, to identify the best biotypes. All samples were analyzed for their phytochemical content, applying a cascade-extraction protocol and hydrodistillation, to obtain the non volatile components and the essential oils, respectively. The extracts contained thirteen polyphenol derivatives, i.e., four flavanones, seven flavones, and two organic acids. Their qualitat…

Biological properties of extracellular vesicles and their physiological functions

2015

The authors wish to thank Dr R Simpson and Dr D Taylor for critical reading of the manuscript and acknowledge the Horizon 2020 European Cooperation in Science and Technology programme and its support of our European Network on Microvesicles and Exosomes in Health & Disease (ME-HaD; BM1202 www.cost.eu/COST_Actions/bmbs/Actions/BM1202). In the past decade, extracellular vesicles (EVs) have been recognized as potent vehicles of intercellular communication, both in prokaryotes and eukaryotes. This is due to their capacity to transfer proteins, lipids and nucleic acids, thereby influencing various physiological and pathological functions of both recipient and parent cells. While intensive invest…

Production of reactive oxygen intermediates by human macrophages exposed to soot particles and asbestos fibers and increase in NF-kappa B p50/p105 mR…

1999

Alveolar macrophages (AM) play a decisive role in the immunologic defense system of the lung and in inflammatory pulmonary pathomechanisms. AM and blood monocytes (BM) were exposed to chrysotile B, soot FR 101, and Printex 90 (P 90). We evaluated the reactive oxygen intermediate (ROI) release of AM and BM after particle exposure. ROI release was measured by chemiluminescence. Thirty-minute exposure caused a significant (up to 2.5-fold) increase in ROI release of AM (100 micrograms/10(6) cells) compared with control experiments (p0.01). Identical exposure conditions for BM resulted in a similar reaction pattern (maximum 2.2-fold increase in ROI release; p0.05). After a 90-min particle exposu…

Background In models of COPD, environmental stressors induce innate immune responses, inflammasome activation and inflammation. However, the interaction between these responses and their role in driving pulmonary inflammation in stable COPD is unknown. Objectives To investigate the activation of innate immunity and inflammasome pathways in the bronchial mucosa and bronchoalveolar lavage (BAL) of patients with stable COPD of different severity and control healthy smokers and non-smokers. Methods Innate immune mediators (interleukin (IL)-6, IL-7, IL-10, IL-27, IL-37, thymic stromal lymphopoietin (TSLP), interferon γ and their receptors, STAT1 and pSTAT1) and inflammasome components (NLRP3, NA…
