A novel SP-1 site in the human interleukin-1β promoter confers preferential transcriptional activity in keratinocytes
1996
To investigate the mechanisms of transcriptional activation of interleukin-1beta (IL-1beta) in non-monocytic cells, we constructed a series of reporter plasmids with the bacterial chloramphenicol acetyltransferase gene linked to various parts of the human IL-1beta promoter and performed transient transfection experiments. We identified a promoter segment that activates transcription most efficiently in keratinocytes. Electrophoretic mobility shift assays (EMSA) with a 43-mer oligonucleotide derived from the functionally identified cis-acting element revealed specific complexes. By competition analysis with transcription factor consensus sequence oligonucleotides and by immunosupershift, tra…
Moduli DSSC integrati nel vetromattone per la costruzione di pannelli traslucidi fotovoltaici multifunzionali
2012
La proposta illustrerà i primi risultati ottenuti nell’ambito di una ricerca, tutt’ora in corso presso il Dipartimento di Architettura dell’Università degli Studi di Palermo, finalizzata ad indagare le problematiche connesse all’integrazione del vetromattone con sistemi di produzione di energia rinnovabile, in particolare, di terza generazione (DSC-Dye Syntetized solar cell - celle fotovoltaiche organiche/ibride). I principali campi di investigazione che si illustreranno saranno connessi alle: tecniche ed i processi di deposizione delle celle sul vetromattone per la costruzione dei moduli, alla scelta del loro migliore posizionamento ed all’analisi delle ricadute, in termini di valutazione …
Reviewing the identity of the Maltese Polypodium (Polypodiaceae) – new evidence from morphology and flow cytometry
2020
The first record of Polypodium from Gozo (Maltese Islands) was described as a new endemic taxon, Polypodium vulgare subsp. melitense, based on its unique set of morphological characters. It was treated as a novelty and designated as a subspecies of P. vulgare mainly due to the lack of paraphyses, the presence of 10–16 annular cells, and a mean spore length of 64 μm. The fern was reassessed by us employing a more rigid morphological analysis and the application of flow cytometry. The absence of paraphyses was confirmed, but the number of annular cells (5–11) and the spore length (70–79 μm) differed from the previous study. These and other morphological traits, the phenology (leaf-shedding in…
Comparison of the effects of chloral hydrate and trichlorethanol on the EEG of the isolated perfused rat brain.
1973
An isolated perfused rat brain preparation was used to compare the effects of chloral hydrate and its metabolite trichloroethanol on the EEG. The concentrations of chloral hydrate and trichloroethanol in the perfusion medium ranged from 1.5 to 5.5 mM. 5, 10, 15, and 30 min after the beginning of the perfusions EEG-recordings were taken. The recordings were evaluated both by a descriptive method and by a simple quantitative appraoch, counting the waves with an amplitude greater than 50 microvolts and averaging this value for a period of 1 sec. The following results were obtained: Both drugs exhibited CNS depressant activity. Between 5 and 10 min of perfusion the effect of trichloroethanol wa…
Interaction of inflammation, thrombosis, aspirin and enoxaparin in CNS experimental antiphospholipid syndrome
2008
Experimental antiphospholipid syndrome (eAPS) induced by immunization with beta(2)-glycoprotein I (beta(2)-GPI) causes behavioral hyperactivity. We assessed the role of thrombotic and inflammatory perivascular factors and standard APS therapies for CNS manifestations. Groups of mice (n=10 per group) were immunized once with beta(2)-GPI (eAPS) or adjuvant (controls) and treated daily from 1 month after immunization with either sham injections, aspirin (1.2 mg/kg) or enoxaparin (1 mg/kg) for 3 months. Serum antiphospholipid antibodies (aPL) and brain levels of tissue necrosis factor-alpha (TNF-alpha) and prostaglandin E (PGE) were then measured by ELISA and thrombin inhibitors by immunoblot. …
Interés taxonómico de los caracteres micromorfológicos en el género Chaenorhinum (DC.) Rchb. (Plantaginaceae)
2017
TEMA: El objeto de la tesis se enmarca en un tema más amplio en el que el grupo de investigación trabaja, en el que se analizan los caracteres morfológicos y los procesos de especiación de las Antirrhineae del Viejo Mundo, junto con sus implicaciones en la conservación de las especies amenazadas. OBJETIVOS: 1. Profundizar en el conocimiento morfológico de las especies ibéricas perennes y así contrastar los tratamientos previos: • Grupo de Chaenorhinum origanifolium; • Grupo de Chaenorhinum macropodum; • Grupo de Chaenorhinum villosum; • Especies gipsófilas de Chaenorhinum. 2. Sentar las bases morfológicas para la diferenciación de los táxones conflictivos o dudosos del género Chaenorhinum, …
Martian zeolites as a source of atmospheric methane
2016
The origin of the martian methane is still poorly understood. A plausible explanation is that methane could have been produced either by hydrothermal alteration of basaltic crust or by serpentinization of ultramafic rocks producing hydrogen and reducing crustal carbon into methane. Once formed, methane storage on Mars is commonly associated with the presence of hidden clathrate reservoirs. Here, we alternatively suggest that chabazite and clinoptilolite, which belong to the family of zeolites, may form a plausible storage reservoir of methane in the martian subsurface. Because of the existence of many volcanic terrains, zeolites are expected to be widespread on Mars and their Global Equival…
New records of Characeae for Sicily (Italy)
2018
During the last year, the first two authors continued their survey of the scarcely known Characeae flora of the island of Sicily: plants were collected in different periods, habitats and areas of the island, and identifications – made on fresh material – were based mainly on Mouronval et al. (2015). We had the opportunity to include here some results deriving from the visit in Sicily made by Klaus van de Weyer in March 2018. Roman Romanov identified some specimens and revised some identifications. Data for Sicily are basically limited to more than one hundred years old reports; data for the national Flora have been completed with recent reports for Sardinia (cf. the work made by Ralf Becker…
