Photoinduced lethal and sublethal toxicity of retene, a polycyclic aromatic hydrocarbon derived from resin acid, to coregonid larvae
2004
A comparative investigation on the acute phototoxicity of retene to vendace (Coregonus albula) and whitefish (C. lavaretus), both having pelagial larvae in spring, was conducted. To test the concept of early warning of sublethal biomarkers in relation to lethality to posthatch stages, we examined the effects of ultraviolet-B (UV-B) and retene on the levels of cytochrome P4501A (CYP1A) and heat shock protein 70 (HSP70) by exposing the animals to elevated levels of these factors for 48 and 72 h, respectively. Whereas UV-B and retene on their own were not lethal, simultaneous retene and UV-B exposure caused very high mortality to both species. The median lethal concentration (LC50; i.e., the c…
On the use of composite indicators for mobile communications network management in smart sustainable cities
2020
Beyond 5G networks will be fundamental towards enabling sustainable mobile communication networks. One of the most challenging scenarios will be met in ultra-dense networks that are deployed in densely populated areas. In this particular case, mobile network operators should benefit from new assessment metrics and data science tools to ensure an effective management of their networks. In fact, incorporating architectures allowing a cognitive network management framework could simplify processes and enhance the network&rsquo
Parametri sierologici e cellulari della specie alloctona Procambarus clarckii
2011
Procambarus clarkii è un animale d’acqua dolce originario del Centro-Sud degli Stati Uniti e del Nord-Est del Messico. Questa specie rientra nella lista delle 100 specie invasive più pericolose al mondo (Delivering Alien Invasive Species Inventories for Europe) in quanto presenta una serie di caratteristiche biologiche, che la rendono una minaccia per la biodiversità. In Sicilia la sua presenza è stata registrata per la prima volta nel 2003 nella riserva naturale “Lago Preola e Gorghi Tondi”, Mazara del Vallo (TP). Allo scopo di conoscere meglio la biologia di questa specie, su esemplari di P. clarkii provenienti dalla riserva di Trapani, abbiamo esaminato i tipi emocitari ed alcune attivit…
Prognostic value of HSP27 in head and neck squamous cell carcinoma: a retrospective analysis of 57 tumours.
2006
Background: The aims of the present study were to assess the prevalence of HSP27 expression in oral squamous cell carcinoma (OSCC) and to verify whether HSP27 can be considered to be a marker of prognosis in patients with OSCC. Materials and Methods: The immunohistochemical expression of HSP27 was evaluated in 57 OSCC, who received standard treatment and monitoring. After grouping for HSP27 expression, OSCCs were statistically analysed for the variables age, gender, histological grading, TNM, staging and survival rate. Univariate and multivariate analyses were performed. Results: HSP27 was found to be reduced in 31 OSCC and was normally expressed in 26 OSCC. The pattern and intensity of HSP…
Voice traffic bicasting enhancements in mobile HSPA network
2014
This paper discusses methods for improving the effectiveness of delivering voice traffic over High-Speed Downlink Packet Access (HSDPA) network by employing transmission diversity with Single-Frequency Dual-Cell (SF-DC) Aggregation that is part of the Multiflow specification. SF-DC Aggregation allows the user to be served at the same time by two different cells. The enhancements discussed in the paper capitalize strongly on the availability of the composed Channel Quality Indication (CQI) feedback at both serving cells. According to the results obtained from the network simulations, the ability to select the better channel for each voice transmission significantly decreases the required tra…
