Amyloid-Beta Induces Different Expression Pattern of Tissue Transglutaminase and Its Isoforms on Olfactory Ensheathing Cells: Modulatory Effect of In…
2021
Abstract Alzhèimer Disease (AD) is characterized by protein aggregates in the brain, including amyloid-beta (Aβ), a substrate for tissue transglutaminase (TG2). We assessed the effect of full native peptide of Aβ (1–42), the fragments (25–35 and 35–25) on TG2 expression and its isoforms (Long and Short) on mouse Olfactory Ensheathing Cells (OECs). The levels of cytoskeletal proteins, Vimentin and Glial Fibrillary Acid Protein, were also studied. The effect of the pre-treatment with Indicaxanthin on cell viability, total Reactive Oxygen Species, superoxide anion and apoptotic pathway activation was assessed. Since Nestin is co-expressed in pluripotent stem cells with cyclin D1, their levels …
Changes in enzymes involved in photosynthesis and other metabolic processes in the fruit of Opuntia ficus-indica during growth and ripening
2011
The aim of this study was to investigate changes in the abundance of a number of enzymes in the peel, core and seeds of fruits of Opuntia ficus-indica (L.) Miller during development. The enzymes studied were phosphoenolpyruvate carboxylase (PEPC; EC: 4.1.1.31), ribulose-1,5-bisphosphate carboxylase/oxygenase (RUBISCO; EC: 4.1.1.39), aldolase (EC: 4.1.2.13), pyruvate, orthophosphate dikinase (PPDK; EC: 2.7.9.1), phosphoenolpyruvate carboxykinase (PEPCK; EC: 4.1.1.49) and aspartate aminotransferase (AspAT; EC: 2.6.1.1). To detect these enzymes, antibodies specific for each enzyme were used to probe Western blots of sodium dodecyl sulphate polyacrylamide gels. Fruit weight increased throughout…
Il ficodindia, stato attuale e prospettive della coltura e dell’uso dei suoi frutti
2015
Il ficodindia continua ad essere una realtà importante in alcune zone semi-aride della Sicilia, arrivando sui mercati anche con la denominazione di origine protetta e, in diversi casi, con la produzione biologica. Negli ultimi venticinque anni il modello italiano è stato largamente utilizzato come punto di riferimento tecnico in tutti i nuovi impianti diffusi ormai in Nord Africa o in California, Cile, Argentina, Sud Africa e nel Vicino Oriente. Tentativi di diffusione esistono anche in India, mentre nel Corno d’Africa c’è ormai una produzioni stabile e importante su diverse migliaia di ettari. Questa specie continua ad avere un ruolo fondamentale, se non insostituibile, nelle regioni semi-…

CO2 FLUXES OF OPUNTIA FICUS-INDICA MILL. TREES IN RELATION TO WATER STATUS
2013
Gas exchange pattern in O. ficus-indica(OFI), refers to the Crassulacean Acid Metabolism (CAM); trees have nocturnal stomata opening, so net CO2 uptake and water loss occur during the cooler part ofthe 24-hour cycle. Succulent cladodes skip severe periods of drought through their water storer tissue (parenchyma). To study carbon fluxes in stress and no stress conditions, an experiment was carried out on 3-year-old irrigated and non-irrigated OFI potted trees; whole tree gas exchange was measured continuously with a balloon system made up by a portable Infrared Gas Analyzer. Continuous measurements(nighttime) during the summer season were useful to assess differences in carbon uptake under s…
Effect of mucilage edible coating on fresh-cut nectarine cultivar ‘Big Bang’
2022
The mucilage (OFI) obtained from cladodes of cactus pear (Opuntia ficus-indica) is useful to produce natural edible coatings to improve the shelf life of fruits. Edible coatings could be used to extend the shelf life of fresh-cut for products. The aim of this study was to evaluate the effect of (OFI) on quality of ‘Big Bang' nectarine slices. After cutting, nectarine slices were dipped in three different solutions: 1) distilled water, mucilage, glycerol (MC); 2) distilled water, mucilage, glycerol, Tween 20 (TW); 3) distilled water as control (CTR) and were stored for 3, 5, 7 and 12 days at 5°C and 90% RH, in polyethylene terephthalate (PET) packages under passive modified atmosphere condit…
Ficodindia
2022
Lo studio degli alberi e la scienza delle coltivazioni distinguono un’Arboricoltura generale da un’altra speciale. Classificazione dottrinaria, questa, ormai consolidata. Pur essendo entrambe dettate dagli stessi principi teorici, trattano in modo complementare ed integrato le modalità tecniche delle loro applicazioni pratiche. Il volume Arboricoltura speciale, pubblicato da Edagricole, colma finalmente un’esigenza molto sentita dal mondo accademico e dal sistema mediatico di informazione pubblica, di crescente importanza, sempre più attento al recupero delle funzioni degli alberi nel mondo in cui viviamo ficus-indica L. (Mill.) (OFI), comunemente nota come ficodindia, appartiene alla famig…

Fruit productivity and carbon gain of Opuntia ficus-indica (L.) Mill. trees
2012
Opuntia ficus-indica (OFI) tree and orchards efficiency has been poorly studied, in terms of relation between orchard lay out, light interception, and cropping efficiency. Apparently, there is no other way to increase orchard production than increasing the number either of trees ha-1 or fertile shoots tree-1, considering that a fruit count higher than 6-7 cladode-1 reduces fruit harvest size. The first option requires a reduction of unit tree size and canopy volume. The second option implies the use of large trees that often reduce their efficiency 12-15 years after planting. In 15-year-old OFI trees spaced 6 5 m apart trained to a globe and 2.5-3.0 m high, stem area index (SAI) calculated …
