The Synapse-Like Interaction between Chloroplast, dictyosome, and Other Cell Compartments during Increased Ethylene Production in Leaves of Rye (Seca…

2000

Rye (Secale cereale L.) plants were treated with an ethylene releaser ethephon (2-chloroethylphosphonic acid) in concentration of 4×10−2 M. We studied electron microscopically, if and how chloroplasts interact with well-documented sites of ethylene production/binding, i.e., with endoplasmic reticulum, dictyosomes, mitochondria, plasma membrane, and tonoplast. During the sharp increase of ethylene synthesis in mesophyll cells of rye leaves, the direct local continguity of chloroplast envelope or envelope protrusions with the above mentioned cell compartments was typical. Moreover, a large number and diversity of versatile chloroplast-dictyosome associations were conspicuous, in which both th…

Effects of Exercise on the Airways

2012

In the last ten years, the effects of exercise on bronchial epithelial cells and inflammatory cells in the airways have been studied in detail, and such new information has been combined with previous knowledge on bronchial reactivity and asthma evoked by exercise in asthmatic patients and athletes. The resulting picture is very complex, and the potential clinical consequences are often contradictory, suggesting the opportunity to define different phenotypes of exercise-associated airway changes (Lee & Anderson, 1985; Haahtela et al., 2008; Moreira et al., 2011a). Studies in asthmatic athletes in the 90’ had began to explore the possibility that airway inflammation might be involved in exer…

Enhanced steatosis by nuclear receptor ligands: a study in cultured human hepatocytes and hepatoma cells with a characterized nuclear receptor expres…

2010

Steatosis is the first step in the development of non-alcoholic fatty liver disease (NAFLD). However, the mechanisms involved in its pathogenesis are not fully understood. Many nuclear receptors (NRs) involved in energy homeostasis and biotransformation constitute a network connecting fatty acids, cholesterol and xenobiotic metabolisms; therefore, multiple NRs and their ligands may play a prominent role in liver fat metabolism and accumulation. In this study we have attempted to gain insight into the relevance of the NR superfamily in NAFLD by investigating the steatogenic potential of 76 different NR ligands in fatty acid overloaded human hepatocytes and hepatoma cells. Moreover, we have d…

LOMO sapiens: de la photographie

2015

Une des questions les plus fréquentes, dans les recherches sur la photographie, est liée à la valeur de médiation de l’image et donc au rapport qu’elle entretient avec la soi-disant réalité. D’un côté, la certitude de la présence devant l’objectif de ce que nous voyons représenté, une copie du monde excluant la nécessité d’un code pour être comprise, de l’autre, l’imposition d’un point de vue situé dans le temps et l’espace qui, par ces choix obligés, porte en soi le germe d’une stratégie de la communication. La sémiotique devient ainsi l’instrument pour analyser ces stratégies, pour rechercher des signifiés plus ou moins cachés, en démontant l’évidence supposée de l’image photographique. D…

Alpha1-antitrypsin heterozygosity plays a positive role in attainment of longevity.

2007

Genes involved in cardiovascular diseases (CVD) play an opposite role in human longevity. The alpha1-antitrypsin (AAT) is a serine-protease inhibitor required for the prevention of proteolytic tissue damage, by neutrophil elastase. The role of AAT in CVD has not been definitively assessed and its effect on longevity has not yet fully been studied. To clarify these points, we have studied the distribution of AAT allele variants in 3 cohorts: 127 young patients affected by acute myocardial infarction (AMI), 255 young controls and 143 centenarians from Sicily. The Z allele frequency was most frequent in centenarians (13.3%), intermediate in healthy young controls (3.1%) and less frequent in AM…

Il capitolo descrive le strutture epigee della pianta arborea. Vengono passate in rassegna le caratteristiche morfologiche e descrittive della chioma, della struttura scheletrica (tronco e branche), delle foglie, delle gemme, di germogli e rami, di fiore e infiorescenze, di frutto e seme.

PIANTE AROMATICHE E MEDICINALI: L’ ENTOMOCENOSI DEL CAPPERO IN SICILIA

2005

Guilds of herbivore insects of medicinal and aromatic plants are generally composed by poliphagous insects that only occasionally are present at high infestation levels. In this paper the main insect pests observed on Capper spinosa (L.) in Sicily are described. The key pests of this crop are Capparimyia savastani (Martelli) – (Diptera: Tephritidae), Asphondylia gennadii (Marchal) (Diptera: Cecidomyiidae), and, the painted bug Bagrada hilaris (Burmeister) (Heteroptera: Pentatomidae). Infestations of other insect pests are also occasionally recorded as the case of the southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae), in the island of Ustica; the cabbage butterfly, P…

An Updated Checklist of the Genus Capparis L. (Capparaceae) in Vietnam, including a New Species from Hon Tre Island

2022

The Indochinese Peninsula is a main center of speciation of Capparis, but the taxonomic treatment of the genus is still critical in this area. With regard to Vietnam, a discordant number of species was recorded by different authors during the last century, whereas various new species have been recently described. An updated checklist of the intrageneric taxa occurring in the country is here presented, including a new species from the island of Hon Tre, Khanh Hoa Province. The genus comprises in Vietnam 37 species, 9 subspecies and 3 varieties, all belonging to Capparis sect. Monostichocalyx. The study area, with 10 endemic species, is confirmed as one of the hotspots of the genus. Three lec…
