Influence of ATPase activity on PPi dependent H+-transport in tonoplast vesicles of Acer pseudoplatanus

1994

Abstract Tonoplast H + -ATPase and H + -pyrophosphatase (H + -PPase) were previously characterized in Acer pseudoplatanus cells (A. Pugin et al., Plant Sci., 73 (1991) 23–34; A. Fraichard et al., Plant Physiol. Biochem., 31 (1993) 349–359). The present study concerns the relationships between these two enzymes in vitro. ATP and PPi hydrolysis were additive and the inhibition of one did not affect the activity of the second one. ATP and PPi H + -transports were also additive. The H + -PPase inhibition did not change ATP-dependent H + -transport but H + -ATPase inhibition inhibited the PPi dependent H + -transport. Because H + -PPase was reported to transport H + and K + into the vacuole (Dav…

Marine alien species in Italy: A contribution to the implementation of descriptor D2 of the marine strategy framework directive

2019

A re-examination of marine alien species or Non Indigenous Species (NIS) reported in Italian Seas, until December 2018, is provided, focusing on establishment success, year of first record, origin, potential invasiveness, and likely pathways, in particular. Furthermore, their distribution is assessed according to the marine subregions outlined by the European Union (EU) Marine Strategy Framework Directive: Adriatic Sea (ADRIA), Ionian Sea and Central Mediterranean Sea (CMED), and Western Mediterranean Sea (WMED). In Italy, 265 NIS have been detected with the highest number of species being recorded in the CMED (154 species) and the WMED (151 species) subregions, followed by the ADRIA (143) …

Analysis of Polymorphism C558T of MAL (TIRAP) in Mediterranean Spotted Fever

2014

Analysis of Polymorphism C558T of MAL (TIRAP) in Mediterranean Spotted Fever M. Bova1, L. Scola1, C. Colomba1, L. Vaccarino1, P. Di Gangi1, G. Santini1, G. Giammanco1, C. R. Balistreri1, D. Lio1, L. Titone Lanza Di Scalea1 1University of Palermo, Palermo, Italy Background: In our previous studies, we have demonstrated that cytokine polymorphisms, such as IFNγ +874T/A or IL-17 SNP (7488T/C), might interfere with R. Conorii infection control. In addition, we have reported that +896A/G TLR4 SNP is a component of a genetic background that might influence the clinical outcome of Boutonneuse fever (Mediterranean spotted fever, MSF). The +869G allele, that attenuates receptor signaling, was actual…

Cytokinin affects nitrate reductase expression through the modulation of polyadenylation of the nitrate reductase mRNA transcript

1993

Abstract Cytokinin (CK) and low-intensity light effects in modulating nitrate reductase (NR) activity, NR protein and NR encoding mRNAs were studied in tobacco cell suspension cultures. NR activity was strikingly enhanced by CK in dark- as well as in light-grown cells whereas it was less affected by light alone. NR protein accumulation was stimulated by the hormone in the light only; then a CK light-dependent regulation of NR activity was suggested. Light enhanced the steady-state levels of hybridisable total NR mRNA and a light-inductive effect was also observed after transfer from dark to light; this effect was dependent on sucrose supply and was enhanced in CK-supplied cells. NR poly(A) …

Experimental Validation of a Novel Method for Harmonic Mitigation for a Three-Phase Five-Level Cascaded H-Bridges Inverter

2019

In modern high-power electrical drives, the efficiency of the system is a crucial constraint. Moreover, the efficiency of power converters plays a fundamental role in modern applications requiring also a limited weight, such as the electric vehicles and novel more electric aircraft. The reduction of losses pushes for systems with a dc bus and a high number of dc/ac converters, widespread in the vehicle, not burdened by a too expensive data processing system. The purpose of this article is to concur to reduce losses by proposing an innovative selective harmonic mitigation method based on the identification of the working areas where the reference harmonics present lower amplitudes. In partic…

Cadmium binding proteins induced in exposed freshwater crayfish Procambarus clarkii.

1989

This work describes results on the characterization of cadmium binding proteins (Cd-BPs) obtained from cadmium exposed freshwater crayfish Procambarus clarkii. After acclimation to laboratory conditions, induction of Cd-BPs was achieved by water exposure at a concentration of 100 micrograms Cd/L during 2, 15, and 30 d. In accordance with the method followed by Engel and Brouwer, in each case two midgut glands were minced and homogenized in Tris-HC1 buffer with PMSF to prevent protease activity and DTT to maintain reducing conditions. The homogenate was centrifuged, heat treated, applied to a column of Sephadex G-75, and eluted with the same buffer (pH 8.6). Absorbances of the fractions coll…

Performance evaluation of CHCP hybrid seawater desalination plants

2007

There are many ways to improve efficiency and reduce fresh water cost in desalination plants, like the integration of two or more desalination systems into a hybrid mechanical/thermal lay-out. Most common results that could be achieved by hybrid systems are savings in pretreatments, overall cost reduction and significant primary energy savings, especially when cogeneration unit are concerned. In this paper a small size (2000 m 3 /day) thermal desalination system (MEE) is coupled with a single-stage seawater reverse osmosis (SWRO) system; the system is fed by a natural gas (NG) reciprocate engine, where heat is recovered both from exhaust gases and from the cooling jacket water circuit.
